Negative Pressure Wound Therapy Owners and Operators Manual
Introduction
Thank you for purchasing the WoundPro® Apex Negative Pressure Wound Therapy System
(NPWT).
The Apex offers providers various options for NPWT. We are able to do this by using the
highest quality materials and advanced electronics. The custom battery system enables the
Apex to operate on battery power for 24 hours.
Please take the time to read the contents of this manual before using the system. If you have
questions about any WoundPro®product please call 1-800-669-4757.
Indications For Use
The WoundPro®Apex Negative Pressure Wound Therapy System may promote wound healing,
through the drainage and removal of infectious material and other fluids from the wound
site using continuous and/or intermittent negative pressure. Patients with chronic, acute,
traumatic, subacute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic
or pressure), flaps and grafts may benefit from the use of this device. The WoundPro Apex is
intended for use in a healthcare facility only.
Types of Wounds Indicated are:
●Diabetic/Neuropathic ulcers
●Pressure ulcers
●Chronic wounds
●Acute wounds
●Dehisced wounds
Contraindications For Use
The use of the Apex NPWT system is not recommended for patients with any malignancy of
the wound, untreated osteomyelitis, non-enteric or unexplored fistulas, and necrotic tissue
with the presence of eschar.
●The Apex NPWT system may be used after debridement of necrotic tissue and the
complete removal of eschar.
Never use the Apex NPWT system where there are exposed blood vessels, organs, or
exposed bone. Do not place the Apex dressings over anastomosis, sutured vessels, or
exposed nerves.
●In the cases of exposed blood vessels, organs or bone, they must first be covered with
a porous, non-adherent wound contact layer prior to initiating Negative Pressure to the
area.

www.accuromedical.com 5
Patient Risk Factors/Characteristics
to Consider
Patients at high risk for bleeding and hemorrhage: Certain patients are at high risk of bleeding
complications with or without the use of the Apex NPWT System. Patients that are at an increased
risk of bleeding (which, if uncontrolled, could be potentially fatal) include the following:
●Patients with weakened or friable blood vessels or organs in or around the wound as a
result of, but not limited to:
❍Suturing of the blood vessel/organ
❍Infection – infected wounds should be monitored closely and may require more
frequent dressing changes. The treating physician should determine if Apex NPWT
needs to be discontinued and what treatment steps need to be taken.
❍Trauma
❍Radiation
●Patients without adequate wound hemostasis
●Patients on anticoagulants or platelet aggregation inhibitors
●Patients without adequate tissue coverage over vascular structures.
●Patients with Vascular Anastomosis
●Patients with Osteomyelitis
●Patients with exposed organs, vessels, nerves, tendons, ligaments
●Sharp edges in the wound (i.e. bone fragments) which could puncture protective
barriers, vessels or organs, which could lead to bleeding.
If Apex NPWT has been prescribed for patients with an increased risk for bleeding/hemorrhage,
the patient should be closely monitored by the treating physician. This device should only be
used in a healthcare facility.
If active bleeding develops suddenly or in large amounts during Apex NPWT, immediately stop
therapy (DO NOT REMOVE THE DRESSING), take appropriate measures to stop the bleeding
and seek immediate medical assistance.
800cc Canister: The 800cc canister SHOULD NOT be used on patients with a high risk
of bleeding, or on patients unable to tolerate a large loss of fluid volume. When using this
canister monitoring capability should be taken into account as well as patient risk factor. This
canister is recommended for acute care use only.
Exposed Vessels/Organs and Sharp Edges: If there are any Exposed Vessels, Organs or
Sharp Edges in the wound, they must be completely covered and protected prior to the use of
Apex NPWT. Sharp edges must either be removed or covered prior to treatment.
MRI (Magnetic Resonance Imaging): The Apex NPWT unit is MR unsafe and should never be
taken into an MRI machine. The Apex unit was not designed for this and should be considered a
fire hazard. Replace the Apex Dressing with an approved dressing for use in an MRI machine.
Hyperbaric Oxygen Therapy: The Apex NPWT unit has not been tested for Hyperbaric
Oxygen Therapy and should be considered unsafe for use with Hyperbaric Oxygen Therapy.
Never take the Apex unit into a Hyperbaric Chamber. The Apex unit was not designed for this
and should be considered a fire hazard.

Precautions
Standard Precautions: Implement standard institutional protocol to reduce the risk of
transmission of bloodborne pathogens.
Continuous vs. Intermittent Apex Therapy: Research is constantly revealing the benefits
of both types of therapy in different cases. The patient’s treating physician should decide
which therapy mode is appropriate for the wound and the circumstances.
Patient size and Weight: Patient size and weight should be considered when prescribing
Apex NPWT. Fluid loss and dehydration should be closely monitored in all patients. Large wounds
in relation to the patient size and weight can have excessive fluid loss and lead to dehydration.
Monitor at risk patients closely. This device has not been evaluated for use in children and infants.
Bradycardia: The Apex NPWT MUST NOT be placed in proximity to the Vagus Nerve.
Circumferential Dressing Application: Caution should be taken when using these
dressings to ensure that the circulation distal to the dressing is not impaired.
System Components
Control Unit
The Control unit is the device that delivers the negative pressure. It is
composed of a pump, lithium ion batteries, software, user interface panel
and a number of sensors that monitor and adjust the vacuum pressure.
Canister Sets
The Apex uses either a 300cc standard canister or an 800cc
large capacity canister. In most cases the 300cc canister should
be used. Each canister set comes with the canister (either 300cc
or 800cc), five feet of dual lumen extension tubing, a patient
connector and slide clamp.
The canister comes with a coagulant built inside to reduce the risk of fluid spills. The coagulant
turns fluids it comes into contact with into gels. There is no discernable difference in the level
of fluid in the canister with coagulant when compared to a canister without coagulant.
The disposal of used canisters should be done in a manner that is consistent with state and
local requirements for medical waste. If you are unsure of your local and state requirements
contact the physician.
CAUTION: Do not use the 800cc canister on patients that are at high risk
of bleeding. Do not use it on patients that cannot tolerate large losses of fluid
volume including children and elderly patients. If considering the use of the 800cc
canister consider the size and weight of the patient, wound type, monitoring
capability and care setting. Generally this canister should be used in acute care
hospitals only.

Power Supply
Each Apex NPWT System comes with an external switching power supply. The power supply
is capable of handling: from 90 to 264Volts AC, from 0.8 to 0.4 Amps, at 47 to 63Hertz. The
power supply comes with several adapters for use with many standard outlets around the
world. Select the adapter that is suited for your outlet and attach it to the power supply. The
other end of the cable connects directly to the Apex control unit.
Dressing Kits
A variety of dressing kits are available for use with the WoundPro Apex. Select the dressing kit
based on the wound that is being treated. All dressing kits come with all required materials to
properly apply the dressing.
Clamp
A clamp is provided with the Apex
pump that allows you to attach the
pump to an IV pole or the head / foot
board of the bed. The clamp is easily
attached to or removed from the back
of the pump with the attached Philips
screw. Simply open the clamp by
turning the handle counter clockwise.
Next determine which direction you
want the clamp to face (side to side for pole mount, or up and down for footboard mount).

●Step 6 – Apply a thin strip of stoma paste (approximately 1”
long X 1/8” thick) on the periwound area where the drain leaves
the wound. Taper the ends of the stoma paste down to a paper
thin thickness. Lay the drain tube across the strip of stoma paste.
Apply a second thin strip of stoma past (approximately 1” long X
1/8” thick) over the top of the drain tube. Press drain tube into
stoma paste creating a seal around the drain tube.
[See Figure E]
●Step 7 – Cut a piece of transparent dressing 1-2 inches beyond
the wound border on each side. Create an airtight seal by
applying the transparent dressing starting with the side opposite
the tubing. Press the dressing down firmly around the entire
wound to ensure the wound environment is sealed. [See Figure
F]
●Step 8 – Monitor the dressing to ensure that the dressing
maintains a vacuum (dressing is contracted) and the volume
of exudate being removed from wound is within physician’s
expectation. Caution: If exudate volumes exceed physician’s
expectations notify physician immediately for further
instructions.
Applying the Foam Wound Dressing Set
●Step 1 – Debride any necrotic tissue and cleanse wound
and periwound area according to institution guidelines and
physician’s orders.
●Step 2 – Cut foam dressing to the shape of the wound. Care
should be taken to ensure that cut pieces of foam do not fall
into wound bed. [See Figure A]
●Step 3 – Place foam into wound bed. A proper fit will result
in wound area being completely covered with no foam
extending beyond the wound edges onto the periwound
area. [See Figure B]
●Step 4 – Cut a piece of transparent dressing 1-2 inches
beyond the wound border on each side. Apply skin prep to
the peri wound area and allow to dry until tacky. Create an
airtight seal by applying the transparent dressing over the
wound and peri wound area. [See Figure C]
●Step 5 – Gently pull up on the transparent dressing over the
center of the wound. Using scissors cut a small hole (between
½ to 1 inch round) over the center of the dressing.

●Step 6 – Remove the protective backing on the Suction Bell.
Apply the suction bell over the hole cut in the transparent fill
in step 4 above. Make sure that the hole is completely covered
with the suction bell.
[See Figure F]
●Step 7 – Slide the tubing clamp onto the Suction Bell tubing.
Attach the Suction Bell tubing to the Patient connector.
●Step 8 – Monitor the dressing to ensure that the dressing
maintains a vacuum (dressing is contracted) and the volume
of exudate being removed from the wound is within the
physician’s expectations. Caution: If exudate volumes exceed
physician’s expectations notify physician immediately for further
instructions.

●Attach the drain tubing to the patient connector on the
extension tubing, which is attached to the canister, by pushing the end of the patient
connector into the drain tube.
●Power up the pump.
●Adjust the setting on the pump as directed by physician.
❍Select either Continuous or Intermittent Mode.
❍Set the pressures and times as directed by physician.
●Open both the pinch clamp and the slide clamp.
●Press the power button to initiate negative pressure therapy. The dressing surface
should contract considerably when the pump is set to run. The system will immediately
start checking for leaks. If it determines there is a leak that it cannot overcome audible
and visual alarms will sound and display (see alarms section).
INFORMATION: Periodically check dressing to ensure that it is place and that the air
tight seal is intact. Check canister and determine volume of drainage.

Alarms
The Apex NPWT system monitors several functions and will alarm if it detects a change in
normal operation. There are both visual and audible alarms. Refer to the following explanation
of alarm conditions to correct the issue. If the problem persists contact Accuro Medical’s
customer service department.
Informational Alarms
Informational alarms are set off when either the battery power is low or the canister has
reached its full mark. The unit will continue to operate normally for a while to allow the
alarm condition to be corrected without interruption in therapy.
Low Power
(3 beeps every minute)
This alarm sounds when the battery has less than 10% of its usable life. When the battery
has less than 10% of its usable life left the battery symbol is displayed
●To fix this alarm, plug the Apex control unit into an outlet.
Canister Full
(3 beeps every minute)
This alarm sounds when the fluid level in the canister has reached its capacity.
●To correct this alarm condition pause the pump and then replace the canister.
Warning Alarms
Warning alarms are set off when a suction line is blocked or there is a vacuum leak, or
the unit is left in standby mode. These conditions affect the ability of the system to work
correctly. The system will stop working until the alarm reason is corrected. Warning alarms
must be addressed as quickly as possible.
Suction Line Blocked
(3 beeps every 5 seconds)
This alarm sounds when the system’s pressure sensor detects a change in the pressure
created by a blockage in the tubing or canister.
●To correct this alarm condition pause the pump and replace the canister and tubing.
