As shown in Figure 4.2.2, open the outlet cover, take out the built-in Water Vessel, the built-in Water Vessel with water, (using distilled water or purified water) as shown in Figure 4.2.2And then put back the vessel and place the cover in the proper position.

Note
The Humidifier and Water Level Sensor should be placed securely onto the vessel to prevent the spill of water.
** Do not fill the vessel with tap water,** which may cause the malfunction of the Water Level Control the water tank and may eventually cause water to spill or leak.
water level should not be above the Highest Level of Vessel line (HLV).
The purpose of the water purification filter material is to remove the hard water scales and improve the water quality. The validity period of each placement is 10-12 months. Colorless, tasteless, and nontoxic, the filter material meets the National Sanitary Standard for Drinking Water & GB1499-1988 and can effectively improve water quality.

3.0 Nebulizer Installation

The external Nebulizer can be installed on the left side of the JorVet J1550 ICU Unit. Insert the power plug into the socket on ICU; insert the nozzle of Nebulizer into the port on the left side as shown in Figure 9.1.1.
Before nebulization, switch on the nebulizer by pressing the switch on the nebulizer and then turn to the operation panel of the ICU.

External Humidifier Installation (Optional J1550D1)

This External humidifier is helping the internal humidifier in our ICU to reach desired RH level more easily, especially in extremely dry environments or under high temperatures. The power plug should be plugged into two flat pins receptacle at the rear left corner on the back of the ICU unit, it will be regulated by the ICU motherboard with special rograms installed. (Note: Do not confuse this socket with another socket for nebulizer, which is next to this socket for a humidifier.) Remove the lid of the inlet at the back of the ICU, expose the portal, and connect the flexible hose from this humidifier to the ICU air inlet. The end with a large diameter is to the back portal of ICU and the end with a small diameter it to the top portal of the humidifier.

Take the water tank out of the base, take away the Valve cup, and fill the water tank with purified or distilled water. Close the Valve cup, and put the water tank on to the base carefully.

After the unit is plugged into either ICU power supply outlet or wall mains, you can start the machine. Rotate clockwise the controller to switch on the unit and the blue indicator lamp will be on. The unit starts working. Rotate the controller knob to adjust the volume of the vapor. Fog can be seen from the outlet port. If a warm vapor is needed, press the button below the power button to switch between the default cool mist mode and warm-mist mode.

Remarks
The “warm mist mode” will be needed when the ICU unit is set at “high temperature + high humidity”, like greater than 28°C + 60% RH, the warm mist will definitely help humidify more quickly.

Note
When LAC alarm can be seen on the humidity display panel, the external and internal humidifiers will both stop working. Fill water in the internal water tank to the maximum level and both of the humidifiers will start to work.
In certain cases, such as avian or other exotics, a desired environment of higher humidity and temperature is preferred. In order to achieve these levels, you must have increased temperature and increased humidity. For instance, at 100°F the humidity can not go beyond 50% relative humidity without the external humidifier.
The external humidifier is not necessary when using the unit on standard mammalian patient like canine and feline.

Nebulization

NOTE: NEVER RUN THE UNIT WHEN THERE IS NO WATER IN THE WATER BASIN.

USAGE WARNING
The treatment process should not exceed 20 minutes for every nebulizing, misuse would possibly cause Pulmonary edema.
To prevent superinfection, please pay close attention to the sterilization of nebulizer, ambient air, and all the related equipment.

Mechanism of Action
The animal respiratory system is an open system, where alveolus is the main air-exchanging place. The object sprayed out of the nebulizer is mainly the mixture of oxygen and medicine – oxygen-medicine aerosol. This kind of aerosol could improve oxygen metabolism and anoxic metabolism significantly; increase the oxygen reserve in organisms. The cavitation effect of compressed air could disperse the liquid medicine into gas phase and turn the liquid into fog form. The suspended particles will get deep into animal respiratory system and treat the focus of infection directly. The feature of air compressing nebulization technique is generating Big Fog Volume with Ultra Small Particle Size (0.5 -5µm); the even fog could go very deep into bronchus and the particles could settle down in deep respiratory system, achieves painless cure effect.

Tips
The smaller the particles are, the better curative effect the nebulization could achieve.
Normally the fog with bigger particles generated from traditional ultrasonic nebulizer would be easier to be observed, as the fog seems to be thicker.

Specialized Medical Nebulizer for Animal – Better Curative Effect
Air Compressor Nebulizer uses a high-pressure gas jet to convert the medicine solution into tiny particles and carry them into deep respiratory system. The size of droplet will affect the settlement site of medical fog.

DROPLET SIZE

|

SETTLEMENT SITE

---|---
1-5µm| Fine Bronchus, Alveolus
5-20µm| Bronchus
20-40µm| Upper Respiratory Tract mainly, Nose, Throat, etc.

The patented Energy Saving Low Noise Compressor (less than 25 decibels) generates high speed air jet from filtered clean air (by anti-bacterial cotton), the air stream disperses the medicine solution from the liquid cup into tiny particles and forms a medicine aerosol. The average size of droplet could reach 2.5µm minus, which could reach deep respiratory system like alveolus and fine bronchus. The medicine is nebulized evenly, no diluted needed, so there is no residues left almost and could achieve very high medicine utilization rate. This device is precisely made medical equipment with very low faulty rate and very good durability, could serve for 1000-1500 hours as minimum lifespan.

Operation Instructions

The nebulizer is easy to operate, please follow the simple steps as follows.
Install the nebulizer on the left side of ICU. Insert the power plug into the socket on the ICU.
Screw off the cup lid and nozzle; pour medicine liquid into the nebulizer cup.
Screw on the cup lid and nozzle, and put the nebulizer back.
Insert the nozzle of the Nebulizer into the port. Turn on the nebulizer by pressing the switch on the nebulizer. And then press Nebulize button on the control panel of ICU to switch on nebulization, the medical fog will be sprayed through grid and get into the ICU chamber. There are two stages of nebulization treatment timing, in which the basic time is 10 minutes. Once the nebulization process is started, the 10 minutes countdown mode starts automatically; pressing the “-” button on the nebulize adjustment button will turn it into 20 minutes mode, pressing the “+” will turn back to 10 minutes mode. Pressing Nebulize button again, on the main control panel when the nebulizing process is running, will switch the nebulizer off.

Tips
There is a hissing noise when nebulization starts, that’s generated from the high-speed airflow. The patented low noise air compressing technology ensures no vibration and no electronic noise when the nebulizer runs. The noise is much lower than the normal level of most air compressor nebulizers, which is around 85 decibels normally.
 When nebulization is ON, the ventilation fans will be turned off to ensure good nebulizing effects, and humidity and temperature control will be turned off too. The humidity alarm will not be triggered in nebulization mode, which will reset in 3 minutes after the nebulization function is turned off.

FUNCTIONS OF THE PRODUCT

1.2 Accurate Temperature Control – Being Equal Everywhere
Heating control adopts “dual duct and double circulation convection heating technology” to allow the temperature to rise quickly, and temperature shock is small to ensure the temperature of the ICU can raise evenly.

2.2 Accurate Humidity Control – Healthy and Balanced
Without being heated, high-frequency oscillation technology is adopted to produce mist. Compared to heating atomization, it can save 90% of energy. During atomization, large amounts of negative ions are released, and have static electricity reaction with smoke and dust in the air, and cause precipitation.

3.2 Negative Ion Generation – Truly Auxiliary Medical Effect
According to the data released by World Health Organization, negative-ion is called “air vitamin”, and an animal needs about 10 billion ecological negative-ions every day; our living environment can only provide about 0.1-2 billion ones. When the negative-ion concentration in the air is up to 400 ones/ cm³, it can satisfy our basic needs for survival; when the negative-ion concentration in the air is up to 1000-2000 ones/cm³, it can satisfy our basic needs of health; when the negative-ion concentration in the air is up to 5000-10,000 ones/cm³, it can Improve our immunity and antibacterial ability; and when the negative-ion concentration in the air is up to 300,000-500,000 ones/cm³, it can improve our natural healing ability, and many diseases can be healed without medication. Negative-ions play a significant role in improving the air quality of a treatment room while improving and maintaining the health of animals.
The JorVet ICU Unit provides a high concentration of negative-ion generator, and the following is the negative-ion test report:

II Principle of Operation

The negative ion generator boosts low voltage to negative high voltage DC through the voltage booster circuit. DC high voltage from the tip of carbon brush is used to produce high corona and lots of high-speed electrons are released. Since electrons cannot exist in the air for a long time (the life of existing electrons is “ns level”), they will be captured by oxygen molecules (02) in the air immediately, and then negative ions are formed; the working principle of which is the same as a natural phenomenon (negative ions are produced when there is thunder and lightning).

The above test report shows that:
The nearby negative-ion concentration of the JorVet J1550 ICU Unit is up to 6 million ones/cm
standard, which has reached the medical-level negative-ion emission standard. It is truly air purifying and is effectively helpful for the rehabilitation and recovery of pets.

4.2 Sterilization Function – Free form Cross-Contamination
A UVC ultraviolet ray is the one that truly has a germicidal effect, and C ultraviolet of which is easily absorbed by DNA of organisms, especially ultraviolet ray of 253.7nm, is the best. UV sterilizer mode is a purely physical method of disinfection, which is characterized by simple and convenient operation, high efficiency, no secondary pollution, easy for management and automation, etc.
The JorVet ICU Unit uses an ultraviolet sterilizer, which is characterized by strong radiation intensity, high stability, and high transmittance to quartz glass tube. The transmittance is of ≥87% and the radiation intensity is at 253.7-254µm and remains stable. Furthermore, high brightness mirror sterilization reaction chamber design is adopted. Compared with similar products from abroad, the sterilization strength increases by 18%-27%.

Generally, the bactericidal action of ultraviolet ray on bacteria and viruses can achieve a sterilization rate of 99%-99.9% in one to two seconds.
The broad spectrum of ultraviolet sterilization is considered the highest, and it can efficiently kill almost all bacteria and viruses.
The ultraviolet sterilizer has no secondary pollution. No chemicals will be added in ultraviolet sterilization, thus, water and its surrounding environment will not be polluted secondly. Furthermore, it will not change any ingredients in the water.
The operation of the ultraviolet sterilizer mode is safe and reliable: traditional disinfection technologies such as chloride or ozone, the disinfectants themselves are highly toxic and flammable substances, while there is no such potential safety hazard in ultraviolet sterilization system.

5.2 Nebulizer Treatment Function – Making the Treatment More Convenient
The JorVet ICU Unit is equipped with an external silent medical atomizer, and biomedical engineering research shows: when the atomized particles are about 10 microns, medicines can only deposit in the mouth and throat, when the atomized particles are about 3-6 microns, medicines can enter into the bronchus, and when the atomized particles are less than 2 microns, medicines can enter into the finest bronchus and alveoli. The JorVet J1550 ICU Unit can produce 0.5-4 micron atomized particles of medicine. Meanwhile, intelligent control quantity of atomization is provided for your selection, and the maximum atomizing volume is up to 0.5ml/min. The atomization in the ICU is even, and the inhalation effect of atomized medicines is obvious. The medical atomizer is characterized by low noise, which complies with pet ICU noise standard.

6.2 Oxygen Concentration Monitoring Systems – A Defense Line to Guard Life
An increase in carbon dioxide concentration is accompanied by a decrease in oxygen concentration. Being anoxic under low oxygen and high concentration of carbon dioxide for a long time will cause pulmonary edema, cerebral edema, metabolic acidosis, electrolyte imbalance, shock, hypoxic encephalopathy, etc. When the carbon dioxide concentration reaches 1000PPM, it will cause dizziness, drowsiness and reduced resistance to pets; when the carbon dioxide concentration reaches 2000-5000PPM, it will cause mild nausea, poor breathing, rapid heartbeat and electrolyte imbalance to pets, and seriously affect the health of pets and their postoperative rehabilitation; and when the carbon dioxide concentration is over 5000PPM, it will cause severe hypoxia, coma and even death.
The JorVet ICU Unit is equipped with a precise oxygen concentration monitor, which can monitor changes in oxygen concentration in the ICU. When the oxygen concentration falls below the set value, and cannot achieve the set value in three minutes, it will trigger the alarm system and start the intelligent ventilation system at the same time, being ventilated with the outside air and thus improve the air quality of ICU, which becomes the most important life line of defense for pets.

7.2 ICU Illumination Function – Creating Comfortable Therapeutic Environment
The JorVet ICU Unit uses ten-level LED lights adjustment, which can simulate various scenes similar to a warm home, dawn, dusk, twilight, etc., providing a cozy and comfortable therapeutic environment for pets.

8.2 Setting of Security Mechanism – No Worries in Use
The JorVet ICU Unit incorporates an intelligent alarm system, and is equipped with a corresponding fault display function, such as extreme temperature and excessive moisture alarm, lack-of-water alarm and main components fault warning lights.
The JorVet ICU Unit is equipped with intelligent switch power keys, dividing into three controls, i.e. Power-on, Start, and Power-off. This design is energy saving and safer to use.

9.2 Human Oriented Structural Design – Reasonable Operation, Clean and Convenient
All equipment components of the JorVet J1550 ICU Unit adopt integrated design. All components are integrated in control frame and completely separated from the control circuit. Only by disassembling the control rack, the whole machine can be disassembled to clean various components including fan, medical devices, heat sink, filter, etc. The operation is extremely convenient, easy for troubleshooting, maintenance and equipment cleaning.
The JorVet J1550 ICU Unit is equipped with two medical device import interface channels, thus external medical equipment (such as oxygen machine) can be connected into the ICU, meanwhile, the side access port adopts medical valve importing design, being convenient for providing IV fluid therapy.

 As shown in Figure 8.2.1-a, open the cover plate of the right Control Rack.
As shown in Figure 8.2.1-b and Figure 8.2.1-c, remove Water Level Sensors and humidifiers from the Water Vessel. Take out the Water Vessel.
As shown in Figure 8.2.1-d, empty the Vessel. Brush off the mineral substance such as water scale or verdigris on the Vessel, Water Level Sensors, and Humidifier. If the filter of the Humidifier fails to work, replace with a new filter.
Install Water Level Sensor and Humidifier, place the water vessel back and secure the cover plate.

Complete Cleaning and Maintenance

Remove and clean parts and assemblies periodically. Desired results are achieved only by cleaning after removal.

Steps for Disassembling Components
Remove four screws from the master control rack on the right to take down the right master control rack, (remove the left master control rack in the same way). See Figure 8.3.1.
 Remove power connection plugs on power cords on one side of the master control rack one by one. Note that plugs have different colors for each electrical component.
Warning: Do not remove control racks or electrical components from control racks immediately after shut down; give it some time to cool down. The heaters in control racks reach a high temperatures.
Remove control racks or contact heaters after a 30 minutes respite after shutdown.

Remove four screws in the fan box and take out the whole heater. Clean the fan. Try not to remove heat sinks from the fan, especially PTC heater bands that cannot be removed from heat sinks. See Figure 8.3.2.
Remove power connection plugs on power cords on one side of the master control rack one by one. Note that plugs have different colors for each electrical component.
Remove and clean filters behind the square plastic section inside the chamber. Take out the humidifier. If it is working normally, it is not necessary to clean the humidifier. For separate cleaning of the humidifier, it is not necessary to remove control racks. See the chapter of separate cleaning of the humidifier above. If the humidifier is definitely damaged or does not work after separate cleaning, remove the humidifier for cleaning and maintenance. See Figure 8.3.3.

As shown in Figure 8.3.3-a, open the cover plate of the Water Vessel of the humidifier, on the control rack.
 As shown in Figure 8.3.3-b, remove Humidifier from the Water Vessel and as shown in Figure 8.3.3-c, remove Water Level Sensors.
