User Manual

DHG-HEALTHCARE.COM

The Dyna-Form® Mercury Advance is a pressure relieving mattress suitable for use with patients at VERY HIGH RISK of pressure ulcer damage.
Offering high levels of patient comfort, this unique system has the facility to “step up” to that of a dynamic mattress when clinically required. Similarly, the mattress’s function can be downgraded as the patient’s condition improves.
These features make it particularly beneficial for use within the patient’s home or palliative care environment and help reduce logistic and decontamination costs. The clinical benefits of a single system are equally applicable to those of a modern hospital setting. A higher maximum weight capacity, up to 40 stone / 254kg, allows the product to meet the modern challenges of those heavier clients. All component parts are interchangeable and replaceable, maximising product life and reducing environmental impact.

Introduction

The Mattress consists of a foam head cell and series of 14 transverse air cells, each containing a unique foam profiled insert, which are in turn held within a foam U Core, all protected by a vapour permeable waterproof cover. The single head end cell and the formers consist of foam only. The transverse cells are arranged into alternate pairs of A and B cells which are filled and emptied in sequence.
In Static Mode, the mattress attains the pressure reducing properties of the Dyna-Form Mercury static foam mattress (details available on request), whilst in Alternating Mode the mattress is able to offer similar properties to a pressure relieving dynamic system.
The digital Control Unit controls a Control Unit that allows air to flow into, or out of the air cells as required according to the operating mode selected. It also maintains the air pressure within the mattress at the required level and controls the action of the audible/visual Audible Warning system in the event of mains supply failure or over or under inflation pressure. A CPR Valve located at the Control Unit end of the umbilical hose permits the rapid deflation of the Mattress in an emergency.

Indications/Contraindications for Use

2.1 Intended Use
Dyna-Form Mercury Advance is a mattress replacement system designed to offer pressure relief and prevention of pressure ulcers to patients spending the majority of their time in bed.
The intended patient population is for individuals aged between Paediatric – Geriatric with a body weight of >10kg.
2.2 Contraindications
The Dyna-Form Mercury Advance should not be used for patients with unstable fractures, gross oedema, burns or intolerance to motion.

Quick Reference Guide

(Frequently used functions)
This is a quick reference guide for the Dyna-Form Mercury Advance System Product Code MAT1210001

A red indicator light signals a warning, notifying that an immediate response is required.
An orange indicator light signals that a particular mode has been selected or to notify of a necessary service that does not require immediate or prompt action.
Power Switch Audible Warning Reset
The power switch simply switches the mains power to the Control Unit on and off.
When the Control Unit detects an Audible Warning condition, this can be silenced (see page 5) and re-set by switching the Control Unit off and then back on again.

CPR Valve
Please ensure that the CPR connector is always placed fully home, prior to inflating the mattress.
NB: The mattress will NOT inflate properly should this not be the case.
The CPR connector is only to be used in the event of a clinical emergency for priority use.
However, disconnecting this function will cleverly deflate air rapidly from the mattress in readiness for transport / static mode.

LED Mode Settings
This symbol when illuminated (The green indicator light) is used to indicate that the equipment is on or ready for use.
When a patient requires a true dynamic function or indeed more pressure in the cells, as they may be uncomfortable or feel as though the support surface is too soft or unstable, then please select a “High” setting (pressure 26mmHg). This must only be used by a trained clinician as often too high pressures can further agitate certain patient conditions.

When a patient requires less pressure in the cells, as they may be uncomfortable or indeed hyper sensitive to cell movement or indeed if the patient is still reddening further, then please select a “Low” setting (pressure 18mmHg). This must only be used by a trained clinician.

This function is used to silence the Audible Warning. The LED will remain lit if the Audible Warning has been silenced previously, however a fault is still detected. Refer to the power switch in order to re-set fully. If the Audible Warning continues to sound  repeatedly, along with an illuminated light, then an engineer must be called.

This symbol indicates an “Audible Warning Failure”.
Please see troubleshooting guide below for how to re-set.

This symbol when illuminated indicates a Service is required.
DHG recommends an annual service. The service light will illuminate every 8760 hours of operation (one continuous year running).

Note: Please ensure (when available) that all securing straps on the base of the mattress are secured onto the MOVING PARTS of the bed frame.
For shut down procedure, see 4.2 Control Unit section.

Installation

5.1 Mattress (This is the applied part type BF)
The device should only be installed and used by a clinician or a trained lay operator. A lay operator shall be considered trained once they have fully read this user manual.
The temperature of the Control Unit may have decreased or increased, whilst in storage or during transportation, beyond the limits of the allowable operating temperatures. Do not use the Control Unit until it has been at room temperature (c.20°C) for at least two (2) hours. This time is required for all components of the Control Unit to reach the normal, recommended operating temperature. Place the Dyna-Form Mercury Advance Mattress directly on to the bed platform ensuring that the Blue multi-stretch waterproof cover is on top and that the umbilical hose is located at the lefthand corner at the foot end of the bed.
Note: The umbilical hose can be located inside the cover under the “Open Here for Air Inlet” printed in the bottom left hand corner of the mattress.
Typically, the mattress user will be placed in a supine position on the mattress.
Wipe the mattress down before covering the mattress with a loose-fitting sheet.
Static Mattress Use
The Dyna-Form Mercury Advance Mattress can be used as a pressure reducing mattress for patients at High Risk of pressure ulcer damage without the need to attach the Control Unit.

Alternating Mattress Use
If / When required, the Dyna-Form Mercury Advance Mattress can be used as an alternating mattress system by attaching the Dyna-Form Mercury Advance Control Unit system.
No other system should be attached to the mattress as the design settings and internal air pressure properties of the Dyna-Form Mercury Advance Control Unit) are specific to this mattress only.

The Dyna-Form® Mercury Advance is a replacement mattress system and should NOT be placed on top of any existing mattress.
The startup time from static to dynamic mode is immediate.
5.2 Control Unit
Hang the Control Unit onto the footboard. The mounting hooks swivel to suit the thickness of the footboard or rail. Connecting the Umbilical Hose to the Control Unit , place the supplied 3-pin electrical plug into the wall outlet and switch on:
(a) Open the zip located at the bottom left hand side of the mattress and pull out the Blue Umbilical hose.
(b) Attach the Blue Umbilical Hose to the Control Unit by connecting the air connector at the end of the Umbilical Hose to the air inlet connector at the bottom left hand side of the Control Unit. Ensure that the Red CPR Release button is located on top of the Air Inlet connector after connection is complete.
(c) Re-close the zip as far as possible without clamping the Blue Umbilical Hose to ensure the mattress and air cells are sealed within the cover.
(d) Shut down is the reverse of items a, b & c above.
The expected operator position of the control unit is from the foot end of the bed. The expected position of the user, under normal use, is centrally placed on the mattress in the supine, side lying or prone position.

Operation

Attach the supplied mains cable to the Control Unit by inserting the “kettle” type connector into the recess located on the left-hand side of the Control Unit. The mains cable has been designed specifically as a removable part to aid in easy replacement should it become damaged in use.
Power cables not supplied by Direct Healthcare Group are not recommended for use with this Control Unit.
The mains plug should be turned off and removed from wall socket as a means of isolation.
Plug the mains cable into a suitable 230v mains socket and switch on the Control Unit using the on/off switch.
After the Control Unit has been turned on both the “High “and the “Low” lights will flash together intermittently until the Control Unit has attained its initial operating pressure. Once the Control Unit has attained its initial operating pressure the “Low” light will stay on constantly and the mattress is ready for use.

6.1 Low / High Settings
The Dyna-Form Mercury Advance Mattress, in Alternating Mode, has two pressure settings. The initial setting that the control unit will revert to upon set up is “Low”. The “Low” comfort setting is ideal for the lighter patient or those who feel discomfort when on a normal alternating air type mattresses system. However, for patients with existing pressure damage or those at Very High Risk, it is recommended that dependant on the clinical judgement of the clinician, the “High” setting is activated by pressing the +/- button once, which is located on top of the Control Unit.
In “High” Mode the Control Unit attains more of the characteristics of an alternating air mattress system whilst still utilising the advantages of the static foam inserts. Repeatedly pressing the ‘mode’ button enables the Low & High modes to be selected in turn.

6.2 CPR Deflation
The CPR system consists of a manually operated button located on the Air Inlet connector  attached to the Control Unit. By pressing the Red Button, which will release the connector locking system, the user can remove the connector unit which will deflate the mattress air system back to that of a static foam mattress.
Note: After a short period as the Mattress deflates the ‘Low Pressure’ Audible Warning is activated and can be cancelled by switching the Control Unit off.

6.3 Troubleshooting
For assistance (if needed) in setting up, using or maintaining the Mercury Advance System, or to report unexpected operation or events, please contact Direct Healthcare Group on the contact details on the reverse of this manual.
6.4 Fire Evacuation System (If Applicable)
The Dyna-Form Mercury Advance can be fitted with an optional fire evacuation system. In the event of an evacuation occurring, the following steps should be taken to provide the safest possible transport of the user:

1. The Dyna-Form Mercury Advance Fire Evac system has clearly marked instructions on the foot and head for ease of use.
2. Open the zips at the shortest ends of the mattress (head end and foot end) to gain access to the Fire Evac harness system.
3.  Pull out harnesses from the mattress and remove the patient securing straps.
4. Place patient securing straps around both the mattress and the patient, adjust the straps accordingly to ensure the patient is secure.
5. Drag both the mattress and the patient on the floor to an area of safety.

Transportation

To change the location of the mattress, remove the Umbilical Cord and allow the mattress to return to its Static Mattress form. Switch off the Control Unit using the on/off switch and disconnect the electrical supply cable from the mains socket. The mattress can now be moved to a new location where it must immediately be reconnected to the mains electrical supply and the Control Unit switched back on. Once the Mattress has been refilled, the ‘Alternating’ mode will automatically revert back to the Low setting and should be reselected to High should this be desired by the clinician.
Warning: The Mattress will not ‘alternate’ when disconnected from Control Unit and /or the mains electrical. Also, refer to environmental conditions section at rear of this manual.
