Introduction
3. Introduction
3.1 About this Manual
This manual is your introduction to the Hydroven®12 system.
You must read and fully understand this manual before using the system.
Use this manual to initially set up the system, and keep it as a reference for day-
to-day routines and as a guide to maintenance.
If you have any difficulties in setting-up or using the Hydroven 12 system,
contact your local Huntleigh sales representative, listed at the end of this
manual.
3.2 Intended Use
The intended use of this product is to manage the list of clinical conditions
detailed in the “Indications” section.
The Hydroven 12 system should be used as part of a prescribed plan of care
detailed in the “Indications” section.
3.3 About the Hydroven 12 system
The system comprises a pump and multi-chamber arm or leg garments. Optional
multi-chamber garment inserts can be used to increase the circumference of the
arm and leg garments.
The pump supplies air to inflate the chambers in the garments via connecting
tubes, allowing the application of controlled pressure to gently compress and/or
massage the limb.
The pump has three inflation modes:
• Sequential.
• Wave.
• LymphAssist®.
Sequential and Wave inflation are used for the treatment of wounds, chronic
venous insufficiency, and venous or dependency oedema. The gentle
compression of the limb increases the return of blood and excess fluids,
improves venous stasis and encourages the reabsorption of waste products.

9
Introduction
LymphAssist inflation is used where there is a requirement to move lymph
away from malfunctioning lymphatics. The gentle, rhythmic massage of the limb
throughout the LymphAssist cycle moves the skin in the direction of the lymph
flow and stimulates the lymphatic vessels, which carry proteins and waste
products.
The pump can also be set to “link” LymphAssist cycles with Sequential or Wave
cycles to treat patients with lympho-venous oedema.
A full technical description of the Hydroven 12 system can be found in the
Service Manual, part number SER0010, available from your local Huntleigh
sales representative.
3.4 Use Environment
Hydroven 12 is suitable for use in hospital, primary care and community
settings. It must not be used outdoors, or in any environment where it may
come into contact with water.

10

Garment and Insert Information
6. Garment and Insert Information
WARNING: Bags supplied with this equipment can present a
suffocation risk; to avoid the risk of suffocation, keep the bags
away from babies and small children.
The Hydroven 12 pump is designed to be used with Hydroven™ 12 garments,
which are available in two sizes for arms and four sizes for legs. Each length
arm and leg garment has a corresponding Hydroven 12 insert piece which
increases its circumference by 17 cm for arm garments and 19 cm for leg
garments.
The length of the tubeset is 140 cm from the pump connector to the foot/hand
end of the garment.
All garments (arm garments, leg garments and garment inserts) have multiple
chambers. Each chamber overlaps the adjacent chamber to provide smooth
and seamless pressure application, and prevent pressure voids or ridging to
the limbs. All garments have zip closures. When closed, the inflating chamber
section overlaps underneath the zip around the whole circumference of the limb
to prevent pressure voids and ridging of the skin underneath the zip section.
The leg garment (and leg garment insert) has a unique 5-chamber foot section
which provides fine application of pressure to the foot, promoting blood and
lymph movement.
Garment inserts are available for arm and leg garments to fit larger limbs. Once
connected to the garment and pump they are designed to inflate in sequence
with the garment to provide unique inflation capabilities for larger limbs.

Hydroven 12 System
7. Hydroven 12 System
The Hydroven 12 pump is designed for table-top use, with the controls situated
at the front of the pump. It comprises a moulded case with non-slip feet on the
base and rear cover, and an integral carry handle.

7.1 Garment Connections
There are two 12-way connectors on the front of the pump. They are covered
by a 2-part, hinged, rubber cover, which is secured to the pump by a strap. The
cover is fitted over both connectors when the pump is being cleaned to prevent
ingress of fluids.
The garments are connected to these two 12-way connectors, which are push-
fit and polarised to prevent incorrect orientation of the connectors. The following
pump/garment connections are possible:
• If two garments are used (either two arm garments, two leg
garments, or one arm/leg garment and one garment insert), one will
be connected to the upper connector and the other connected to the
lower connector. The two connections are interchangeable - both
garments will inflate at the same time and to the same pressure.
• If only one garment is used, it must be connected to the upper
connector and the rubber cover must be securely fitted to the lower
connector (folded as shown).
All garments (arm garments, leg garments and garment inserts) have multiple
chambers. The chambers are inflated in a pre-determined sequence, according
to the inflation modes detailed below. (Refer to “Inflation Modes”).
The inflation of the chambers follows a preset pressure gradient, but the
deflation of the chambers is effectively instantaneous.

17
Hydroven 12 System
7.2 Operating Modes
Refer to “Pump Controls and Indicators” for a description of the controls and
indicators on the pump.
The pump has the following three operating modes:
7.2.1 Standby
After the mains power supply has been switched on to the pump, the pump will
perform a short self-test and then go into Standby.
In Standby mode:
• The Run and Sleep mode indicators are extinguished.
• The pump shows the previously selected therapy settings.
• The pump is ready to start therapy. Press the Run/Standby button to
start therapy.
7.2.2 Sleep Mode
If the pump has been in Standby for 10 minutes without any of the buttons being
pressed, it then goes into Sleep mode to conserve power.
Note: The pump can be left in Sleep mode for long periods without
disconnecting the mains power.
In Sleep mode:
• Only the Sleep mode indicator on the control panel is illuminated.
• All other displays and indicators are extinguished.
• Press the Run/Standby button to put the pump into Standby.
7.2.3 Run Mode
The pump is in Run mode for the duration of the therapy session, while it is
inflating and deflating the garments.
In Run mode:
• The Run mode indicator will be illuminated.
• The pump automatically stops at the end of the selected therapy time
and the garments are deflated.
• The pump can be stopped during the therapy by pressing the Run/
Standby button.
Note: Loss of mains power will halt therapy.

18
Hydroven 12 System
7.3 Inflation Modes
The pump has the following three inflation modes:
7.3.1 Sequential Inflation
1. The first garment chamber starts to inflate.
2. When the first chamber has been inflated to the correct pressure, the second
chamber starts to inflate.
3. This sequence continues for all 12 chambers.
Note: In Sequential mode, all chambers are kept fully inflated while
subsequent chambers are inflated.
4. After the final chamber has been inflated, all chambers are then deflated
simultaneously.
5. The pressure in each chamber is less than the pressure in the preceding
chamber, and the pressure in the final chamber is set to 60% of the pressure
in the first chamber.
7.3.2 Wave Inflation
1. The first garment chamber starts to inflate.
2. When the first chamber has been inflated to the correct pressure, the second
chamber starts to inflate.
3. When the second chamber has been inflated to the correct pressure, the first
chamber starts to deflate and the third chamber starts to inflate.
Note: The patient may feel that more than one chamber is inflated at
any one time.
4. This sequence continues for all 12 chambers.
5. The pressure in each chamber is less than the pressure in the preceding
chamber, and the pressure in the final chamber is set to 60% of the pressure
in the first chamber.
Note: Wave inflation is also known as “peristaltic” inflation.

7.3.3 LymphAssist Inflation
Refer to the diagram below for the LymphAssist cycle.
Note: Chamber 1 is at the distal (foot/hand) end and chamber 12 is at
the proximal (thigh/shoulder) end.
1. On initial application, the LymphAssist therapy starts with a single peristaltic
Wave inflation from chamber 1 to chamber 12.
2. A LymphAssist cycle is comprised of the following sequence of inflations/
deflations, starting at chamber 12, then 11, 10, etc., down to chamber 1:
• There are 5 pulses where the chamber is inflated and
deflated. These are referred to as LymphAssist pulses.
• This is followed by a single “partial”-peristaltic Wave inflation of
part of the garment - between the next chamber and chamber 12.
For example, at chamber 5, the 5 LymphAssist pulses are followed by a
partial-peristaltic Wave inflation from chamber 6 to chamber 12.
