GENERAL INFORMATION
CAUTION: United States Federal law restricts this device to sale by or on the order of a physician or physician’s
designated licensed healthcare practitioner
NOTES: Use this tourniquet system according to the policies in your practice setting. The following information on
intended use, precautions, contraindications, and adverse effects are offered as a guide to assist in this process
INTENDED USE
This device is intended to be used only with a Delfi BFR Tourniquet Cuff by a physician or physician’s designated licensed
healthcare practitioner to preoperatively and/or postoperatively exert enough pressure on the arterial blood flow in a
patient’s extremity to reduce or totally occlude blood flow into the limb.
INDICATIONS FOR USE
This device is indicated for use on patients for whom a physician or physician’s designated licensed healthcare
practitioner has indicated preoperatively and/or postoperatively blood flow restricted therapy.
The target treatment group shall be drawn from those patients who require or may require perioperative procedures to
affect the structure or function of limbs and/or to treat or mitigate diseases associated with limb anatomy or physiology.
A physician or physician’s designated licensed healthcare practitioner may indicate treatment with the Delfi PTS for BFR
for patients who may be unable to withstand the stresses of high load therapies (e.g. persons recovering from injury,
persons with chronic health conditions, or persons suffering from other musculoskeletal conditions).
NOTES: Physician or physician’s designated licensed healthcare practitioner include but not limited to: physiotherapists
and surgeons, physiotherapy clinics, sports teams with resident physiotherapists/athletic trainers/physicians.
CONTRAINDICATIONS
Delfi recommends that users regularly review published medical literature for factors that warrant careful consideration
before prescribing blood flow restriction techniques. The current list of contraindications has been developed through
current research on blood flow restriction therapy, as well as through the well-established risks for tourniquet use in
surgery which are also contraindicated for use in blood flow restriction. The listed contraindications are:
Cardiovascular disease:
•Unstable and/or severe hypertension
•Compromised vascular circulation (e.g. peripheral vascular disease)
•Hypercoagulable states (blood clotting disorders)
•Varicose veins in the indicated limb for BFR intervention
•Atherosclerotic vessels causing poor blood circulation
•IV drug use in the indicated limb for BFR intervention
Musculoskeletal injury:
•Recent muscle trauma or crush injuries
•Postsurgical excess swelling
•Open fractures
•Skin graft in which all bleeding points must readily be distinguished
•Secondary or delayed procedures after immobilization
•Post-traumatic lengthy hand reconstruction

GENERAL INFORMATION
6GENERAL INFORMATION
1
•Direct peripheral nerve injury
Other factors:
•Uncontrolled diabetes mellitus
•Sickle cell disease or trait (relative contraindication, see Precautions in Use under Section 1 General Information)
WARNINGS
This device is not indicated for use on patients during surgery.
Caution should be exercised when prescribing BFR therapy for patients with compromised cardiac function including
silent myocardial ischemia or left ventricular dysfunction.
If serious adverse effects are seen while performing BFR therapy, the intervention should be stopped. The physician or
physician’s designated practitioner shall use their discretion throughout use of the BFR therapy to identify any serious
adverse effects which may require the patient to stop the therapy. Such serious adverse effects include but are not
limited to excessive limb swelling or signs of nerve injury.
This product is subject to wear and deteriorates with use. It is essential to inspect this device before each use. Refer to
Utilization under Section 3 BFR Cuff Utilization. If the cuff fails to pass inspection, it is no longer usable and must be
discarded. Use of a damaged cuff could result in one or more of the following events: loss of cuff pressure; release of the
cuff from around the patient’s limb; movement of the cuff on the patient’s limb; excessive leakage of the cuff pressure; or
pinching of tissue under the cuff.
The cuff should only be connected to a tourniquet instrument known to be in an operable condition. Refer to Section 4
Maintenance for information on testing and maintenance.
PRECAUTIONS IN USE
Delfi recommends that users regularly review published medical literature for factors that warrant careful consideration
before performing blood flow restricted techniques. The following clinical conditions have been cited in publications as
factors that should be carefully considered before performing blood flow restricted therapy and/or for which there is not
sufficient clinical evidence to be a listed contraindication:
Cardiovascular conditions:
•Coronary heart disease
•Existing or at increased risk for venous thromboembolism
•At increased risk of hemorrhagic stroke
•At increased risk of exercise induced rhabdomyolysis
•At increased risk of atrial fibrillation or heart failure
•Prior use of medications known to increase blood clotting risk
•Induration/Marfan syndrome
•Vascular endothelia dysfunction
•Prior Hemophilia
•Cardiopulmonary conditions
•Silent myocardial ischemia
•Left ventricular dysfunction

GENERAL INFORMATION
7GENERAL INFORMATION
1
Musculoskeletal conditions:
•Existing compartment syndrome
•Open soft tissue injuries
•Extremity infections
Patient considerations:
•Pediatric patients
•History of smoking
•Pregnancy
•Dehydration
•History of cancer
System Handling:
•The tourniquet system must be well calibrated and in operable condition. Accessories should be checked regularly
for leaks and other defects.
•The tourniquet cuff must never be punctured; therefore, any sharp objects which may be used near the system
must be handled with care.
•When cleaning, carefully follow the cleaning and assembly instructions for the tourniquet cuff and instrument.
Patient Considerations:
•Prolonged ischemia may lead to temporary or permanent damage to tissues, blood vessels, and nerves. Tourniquet
paralysis may result from either excessive or insufficient pressure. Prolonged tourniquet time can also produce
changes in the coagulability of the blood with an increase in clotting time.
•When using a tourniquet on patients with sickle-cell disease or trait, severe post-use pain may result in the applied
limb which may be caused by sickling of cells. Test for hemoglobin type and level before using a tourniquet on
patients with sickle cell disease or trait. When the tourniquet is used for these patients, closely monitor the patient’s
PO2 and pH since sickling is dependent on oxygen tension and pH.
Application and Use:
•Select the proper cuff size to allow for the overlap recommended by Delfi Medical Innovations Inc. Refer to the Cuff
Size guide under Section 3 BFR Cuff Utilization. Too much or too little overlap may cause cuff rolling and telescoping,
unexpected release of the cuff from the limb, and/or undesired pressure distribution on the limb.
•The skin under the tourniquet cuff may be protected from mechanical injury by smooth, wrinkle free application of
the cuff Follow the Delfi’s recommendation for limb protection material under the cuff; refer to the Application
guide under Section 3 BFR Cuff Utilization. In general, a limb protection sleeve designed specifically for the cuff
provides the best protection.
•The tourniquet cuff must be applied in the proper location on the limb. Tourniquet pressure and the time the
tourniquet is inflated on the limb should both be minimized. There is additional potential risk to superficial nerves
in unprotected areas; never apply a tourniquet over an area where major nerves may be directly compressed
against bone (e.g. peroneal nerve near the proximal head of the fibula). Never apply a tourniquet over the joints of
the limb. Do not readjust an already inflated cuff by rotating it because this produces shearing forces which may
damage the underlying tissue.
•Limb Occlusion Pressure (LOP) is defined in the medical literature as the minimum pressure required to stop the
flow of arterial blood into the limb distal to the tourniquet cuff, at a specific time in a specific tourniquet cuff applied
to a specific patient’s limb at a specific location. For each patient, the tourniquet pressure should be set to a
percentage of the LOP as recommended by the supervising physician or physician’s designated licensed health care
practitioner.

GENERAL INFORMATION
8GENERAL INFORMATION

•Observe the cuff during inflation and periodically while inflated to ensure the cuff is not migrating on the limb. If the
tourniquet cuff migrates on the limb during use, deflate and reapply the cuff. Inflate the cuff and observe for
migration. If migration persists, replace the cuff.
•In case of incomplete or improper inflation, the tourniquet cuff must be fully deflated before cuff reinflation.
•The deflated cuff and any underlying limb protection material should be completely removed as soon as tourniquet
pressure is released and the prescribed blood flow restriction therapy protocol is complete.
ADVERSE EFFECTS
Possible adverse effects which may occur from performing blood flow restriction techniques using a pneumatic
tourniquet include bruising at the site of the cuff, numbness, cold feeling, venous thrombus, fainting/dizziness, delayed
onset muscle soreness, increased perceived exertion/pain/discomfort, stiffness, weakness, skin discoloration, exercise-
induced rhabdomyolysis. Symptoms of tourniquet paralysis are motor paralysis and loss of sense of touch, pressure, and
proprioceptive responses.

GENERAL DEVICE FUNCTION
The Personalized Tourniquet System for Blood Flow Restriction (PTS for BFR) and Accessories provide temporary
reduction of arterial blood flow for a predetermined length of time. The system is designed to assist a trained and
licensed physician or physician’s designated healthcare practitioner in the treatment for the structure and function of a
patient’s limb(s) by reducing blood flow to a patient’s extremities combined with or without muscle activation, to
stimulate biological processes which reduce muscular atrophy and increase muscle strength.
The Delfi PTS for BFR has the capability of determining a patient’s Personalized Tourniquet Pressure (PTP) as a
percentage of the patient’s Limb Occlusion Pressure (LOP) by automatically measuring LOP. The PTS for BFR maintains
the cuff pressure at the pressure set-point for the time period(s) required for a BFR therapy session.
The Delfi PTS for BFR has the capability of measuring the patient’s Limb Occlusion Pressure (LOP) and recommend a
Personalized Tourniquet Pressure (PTP) based on the LOP for use during a BFR therapy session.
LOP is the lowest pressure required for a specific cuff to stop the flow of blood in the extremity of a specific patient at a
specific time and location. It is personalized to the patient and accounts for patient’s physiology, limb characteristics, cuff
properties and cuff application. PTP is a personalized pressure that is a percentage of the LOP. The percentage of LOP
used for PTP depends on the BFR therapy prescribed by the physician or physician’s designated licensed healthcare
practitioner.
There are two types of BFR therapy: standard “BFR”, and “Cyclic BFR”.
Standard BFR therapy involves restricting arterial blood flow into an extremity of a patient while the patient performs
low-intensity movements (aerobic or resistive). BFR rehabilitation may involve the patient performing exercise
repetitions for a number of repetition sets (sets) for strength gain, or may involve the patient performing walking or
cycling exercise for a longer duration for increasing the patient’s endurance. Owens Recovery Science (ORS), a leader in
BFR rehabilitation, recommends strength protocols with 30 reps, 15 reps, 15 reps, and 15 reps (REPs) with 30 seconds
rest periods in between (Rest Time). Typically, strength protocols require 6-8 minutes and endurance protocols require
15-20 minutes of inflated time (Inflation Time). ORS recommends setting PTP to 50% or 80% of LOP when performing BFR
rehabilitation on an upper limb or lower limb, respectively.
Cyclic BFR (C-BFR) therapy involves the cyclical application of arterial restriction or occlusion, and reperfusion of a
patient’s extremity. PTP, duration at which the cuff is inflated (Inflated Time) and deflated (Deflated Time), and the
number of inflation cycles (Inflation Cycles) may be adjusted based on the prescription of the physician or physician’s
designated licensed healthcare practitioner. During C-BFR, the patient may perform low-intensity exercise or may remain
inactive.
Delfi PTS for BFR provides twelve selectable BFR protocols for BFR or C-BFR therapies. Six of these protocols are based on
ORS recommendations with restricted adjustment capabilities. The remaining six protocols are fully customizable within
the instrument’s limits.
