The proposed pump is currently being used on the market as the PlexiPulse*, which has already met UL544
standards. Other pumps, however, which are not presently UL listed, may be substituted in the future.
This manual will deal with two models of the PlexiPulse® pump. These models can be differentiated by the color
of the Power button located on the front face of the pump case. These models will be referred to throughout this
manual as a “Red Button Unit” or a “Green Button Unit”.
The PlexiPulse® pump is to be used with PlexiPulse® wraps only.

| INTRODUCTION |
The PlexiPuise® pump is a pneumatic compression device designed to increase blood flow in non-ambulatory or resting
patients.
— The veins in the calf and foot provide a natural pump that, when compressed, push blood back toward the heart.
The PlexiPulse® pump helps this natural calf and foot pump circulate blood throughout the system when the
normal circulatory process is disabled due to surgery, injury, or disease.
The PlexiPulse® pump is connected by tubing to individual inflatable calf wraps and foot wraps that can be
operated together or independently. Each calf and foot wrap is designed to provide a comfortable fit around the
calf and foot, with an air bladder that squeezes “all around” the soleal sinus in the calf and venous plexus in the
arch as well as collateral veins in both the calf and foot.
Location (one or both calves, one or both feet, or one or both calf and foot combination), frequency, and intensity
of pulsation, as well as duration of air bladder inflation is controlled by a microprocessor and monitored by a
pressure feedback system built into the pump, ensuring the patient will receive the desired pulsation intensity.
INDICATIONS
The PlexiPulse® pump is indicated for patients who would benefit from a pneumatic compression device that
would heip to:
e Prevent Deep Venous Thrombosis (DVT).
e Prevent venous stasis.
e Enhance arterial circulation.
« Reduce post-operative pain and swelling.
e Reduce edema.
e Reduce wound healing time.
e Treat and assist healing of cutaneous ulceration.
e Reduce compartmental pressures.
e Reduce the need for anticoagulant medications.
CONTRAINDICATIONS
Patient conditions for which the PlexiPulse* pump is contraindicated include:
e Presumptive evidence of congestive heart failure.
e Suspected pre-existing DVT.
8/95 1-1 Introduction

SAFETY TIPS
Do Not Walk in Foot Wrap - Foot wraps must always be removed before a patient is allowed to walk.
Regular Skin Assessments - Skin condition should be assessed regularly, particularly for:
- e Vascularly compromised patients.
e Diabetics with reduced feeling in extremities.
Liquids - Avoid spilling liquids on any part of the pump case. If spills do occur:
e Clean liquid from case wearing rubber gloves or other electrical insulators to avoid shock.
e Check operation of controls and other components in area of spill.
e Perform applicable troubleshooting procedures. See the Troubleshooting and Maintenance chapters of this
manual for more information.
NOTE: Liquids remaining on the electronic controls can cause corrosion which may cause the electronic components
to fail. Component failures may cause the unit to operate erratically, possibly producing potential hazards
to patient and staff.

| FEATURES |
The PlexiPulse® All-In-One System
_ The PlexiPulse® All-in-One system offers a therapeutic edge in foot and leg compression. The system can
accommodate any of the following PlexiPulse® wraps with just one pump; the user can even use different wraps
on the left and right side at the same time.
e Foot Wrap - Helps provide excellent proximal DVT prophylaxis by squeezing “all around” the venous plexus in
the arch and collateral veins of the foot.
e Calf Wrap - Shown with numerous products to help provide good distal and proximal DVT prophylaxis.
» Combo Wrap - A combination of both therapies may provide the most aggressive DVT prophylaxis.
e Custom Wrap - Helps provide compression therapy for under cast and other specialized uses.
Individualized Patient Therapy
When prescribed, the PlexiPulse® pump can be adjusted to provide pulsation therapy that is customized in
location (one or both sides), frequency, intensity, and duration to meet individual patient needs. The ranges of
adjustment, as well as the “standard” pulsation settings, are listed below:
« Location of Pulsation - Left, Right, or Both sides - “standard” is Both sides.
e Frequency of Pulsation (Cycle Time) - 20 to 60 seconds - “standard” is 20 seconds.
e Intensity of Pulsation (Pressure Settings) - 1 to 5 - “standard” is 3.
e Duration of inflation (Hold Time) - 1 to 5 seconds - “standard” is 2 seconds.
“Ramping-Up” to Desired Impulse Pressure
The PlexiPulse® pump begins pulsation at an intensity (pressure) less than that selected, and “ramps-up" to the
desired amount of pressure over a period of approximately 2-3 minutes. “Ramping-Up” helps to improve patient
compliance by increasing comfort.
Pressure Feedback
The intensity of pulsation (inflation pressure of the air bladder in the disposable wrap) is automatically monitored
and adjusted to ensure the patient receives the desired pulsation intensity. If the disposable wrap is loose, air
bladder pressure is increased; if the disposable wrap is tight, air bladder pressure is decreased.
Pressure feedback and the resulting automatic compensation help to avoid the incidence of skin breakdown,
patient discomfort, reduced therapy, and constant alarming, common in other extemal pneumatic compression
devices.
Microprocessor Control Panel
The PlexiPulse* pump has a user-friendly, menu-driven, control panel which provides prompts to lead the user
through selection and operation of the pump functions. See the Quick Reference Guide and Operating
Instructions sections of this manual for more information.

PATIENT PLACEMENT |
Before beginning patient placement, personnel should familiarize themselves with the procedures outlined in the
Quick Reference Guide and Operating Instructions chapters of this manual as well as the procedures listed
_ below:
NOTE: The procedures described below are for placement of the PlexiPulse® pump in a hospital environment where
property ground three-prong outlets are provided. Before a PlexiPulse® pump can be placed in a home
environment, outlets in the home must be checked for proper grounding. If the home outlet to be used is not
a property ground three-prong outlet, a Patient’s Assumption of Risks form must be obtained from the KCI
Legal Department and a properly grounded UL-listed two-prong adapter must be used.
1. Hang the PlexiPulse® pump case on footboard of bed using adjustable hanging arms located on each side of
the pump case.
2. Apply disposable wrap(s) as shown below:
Right/Left Foot Wrap Instructions
@ Position foot over disposable as shown. Fold
first flap over top of foot.
© Fold second flap (with hook-and-loop patch)
comfortably over top of first flap and secure.
© Wrap back strip comfortably over heel and
secure.
Universal Calf Wrap Instructions
@ Position Calf Wrap behind calf as shown. Fold
first flap over top of leg.
FOOT AND CALF WRAPS
© Fold second flap (with hook-and-loop patch)
comfortably over top of first flap and secure.
Custom Wrap Instructions
@ Wrap extremity with stretch cotton several times.
© Using a Custom Wrap (part #235502), partially inflate bladder (two-thirds to three-quarters) by blowing air
into tubing. Kink tube to prevent leakage. This will help ensure there is enough room for the bladder to
inflate.
Place bladder in location of desired compression, ensuring red spigot is easily accessible.
Wrap cast material around the bladder and under the red connector several times to help build up the
base and to help prevent pain at the connector.
Finish the cast.
