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.

Pulsation Therapy
1. When tuming the pump on or after silencing the alarm, pulsation
always begins at a lower amount of pressure than was selected, —
and then “ramps-up" to the selected amount of pressure over a
period of approximately 2-3 minutes. “Ramping-up” helps
maximize patient comfort.
2. As pulsation is provided, inflation pressures for each side are
monitored. With pressure feedback, the pump will automatically
adjust its output to provide the amount of pressure selected,
compensating for a disposable wrap that is too loose or too tight.
3. If pressure oddities (i.e., disconnected external wrap, kinked
hose, a damaged wrap, or an open disposable wrap) are
detected for 5 consecutive cycles, pulsation will continue while
an audible alarm will sound.
NOTE: The alarm can be temporarily silenced by pressing either
the “А”, “В”, “С”, or “Alarm Silence” button. The unit will
“ramp-up”, perform approximately 5 cycles, and then alarm
again if the abnormality has not been corrected. Refer to
the Alarm Procedures section of this chapter for more
information.
Additionally, if a unit malfunction is detected, an audible
alarm will sound and the unit will stop pulsing. If turing
the pump off and on and reconnecting the tubing does not
resolve the abnormality, contact your local sales
representative or NuTech® Customer Service (800)
446-6303.
