Pneumatic Tourniquet System

Automatic pneumatic tourniquet system is a professional equipment used in medical surgery, mainly through the air pump to press the gas into the pressure cuff, generating uniform pressure effect on the blood vessels of the limbs, controlling the local blood flow, and realizing the bloodless operation environment during the operation.

Compared with traditional manual hemostatic devices, it has the advantages of easy operation, precise pressure and high safety.

Key Applications of Pneumatic Tourniquet System

Orthopaedic Surgery

•Extremity Procedures: Used in surgeries like fracture repositioning, joint replacements (e.g., knee, hip), and internal fixation to minimize bleeding and provide a clear surgical field.
•Amputations:Effectively controls bleeding during amputation surgeries, aiding surgical efficiency.
•Limb Deformity Corrections: Ensures a bloodless environment for successful limb deformity surgeries.

Plastic surgery

•Flap Transplantation:Helps minimize bleeding during skin flap transplantation or repair, ensuring a clear view for surgeons.
•Limb Reconstruction:Assists in scar repair and deformity corrections on limbs.

Hand Surgery

•Fine Hand Surgeries: Used in tendon and nerve repair, and reimplantation of severed fingers to provide a bloodless operating environment for precise procedures.
•Trauma Repair:Essential for controlling bleeding during hand trauma surgeries, stabilizing the patient for further interventions.

Vascular Surgery

•Repair & Reconstruction:Temporary blockage of blood flow during vascular repairs or transplants enables safer surgical interventions.
•Circulation Testing:Used for the tourniquet test to assess blood circulation in limbs.

Sports Medicine

•Arthroscopic Procedures:In knee and shoulder arthroscopy, it reduces intra-articular bleeding, improving the clarity of the surgical field.
•Injury Repair:Facilitates ligament and cartilage repairs, enhancing surgical outcomes.

Trauma Surgery

•Acute Trauma:Provides temporary hemorrhage control in severe limb trauma (e.g., car accidents), stabilizing the patient before surgery.
•Open Fracture Repair:Reduces bleeding during open fracture surgeries, ensuring optimal conditions for surgical repair.

Paediatrics

•Pediatric Limb Surgeries:The pneumatic system adjusts pressure for the unique needs of children’s limbs, ensuring safety and effectiveness during orthopaedic or hand surgeries. •Congenital Deformity Surgery:Aids in correcting congenital limb deformities with minimal bleeding.

Rehabilitation

•Ischemic Training:In rehabilitation, the tourniquet system is used for ischemic training, which promotes muscle recovery and enhances function by briefly restricting blood flow.

Emergency or Field medicine

•Temporary Haemostasis:Used in emergency settings to control severe bleeding from limb injuries, buying critical time for transport or further surgery.
•Battlefield First Aid:In disaster zones or on battlefields, the pneumatic tourniquet serves as a life-saving tool for controlling hemorrhage

Components of automatic pneumatic tourniquet

1. Control Host: the core part of the equipment, responsible for regulating the pressure, control time and monitor the operating status of the equipment.
Main Components:
Display, control panel, built-in pump system, safety alarm system

2. Pressure Cuff: a component in direct contact with the patient’s extremity used to apply uniform mechanical pressure to block local blood flow.

3. Connection Line: connects the main unit to the pressure cuff to transmit air pressure.
4. Power supply system: Provide the power support required for the operation of the equipment to ensure a long period of continuous work.

5. Accessories And Consumables
Common Accessories: replacement cuffs, cleaning kits, protective caps for line connections
Consumables: Cuffs and connecting tubes may need to be replaced periodically to ensure hygiene and reliable performance.

Guidelines for Using the Pneumatic Tourniquet System

Indications and Contraindications

•Indications:
Extremity surgeries (e.g., orthopaedics, hand surgery, plastic surgery).
Acute trauma hemorrhage control.
Limb ischemia pre-treatment or rehabilitation.
•Contraindications:
Severe peripheral vascular disease (e.g., atherosclerosis).
Limb infection or skin damage.
Severe hypertension or cardiovascular disease.
Coagulation disorders.
Read More

Pressure Setting

•Adjust Pressure:
Tailor pressure based on patient factors like age, limb thickness, and blood pressure:
Upper limb:systolic pressure +50-75 mmHg.
Lower limb: systolic pressure +100-150 mmHg.
For pediatric patients, reduce pressure.
•Avoid Excessive Pressure:
Excessive pressure can cause nerve damage, muscle ischemia, or skin necrosis.

Duration of Use

•Time Limits:
Adults: 60 minutes for upper extremities, 90 minutes for lower extremities.
Children: No more than 60 minutes.
•Intermittent Use:
For longer procedures, release the tourniquet intermittently (10-15 minutes every 60-90 minutes) to restore blood flow.

Tourniquet Placement

•Upper Extremity:
Place in the upper third of the arm, avoiding radial nerve compression.
•Lower Extremity:
Place in the upper third of the thigh, avoiding the inguinal region.
•Skin Protection:
Place a soft pad between the tourniquet and the skin to prevent direct pressure.
Read More

Postoperative Care

•Tourniquet Release:
Deflate slowly to prevent sudden blood pressure fluctuations.
•Limb Examination:
Assess circulation, nerve function, and skin condition in the distal limb.
•Monitor for Complications:
Watch for nerve injury, muscle ischemia, or skin damage.
Read More

Intraoperative Monitoring

•Monitor Pressure:
Continuously check the tourniquet pressure.
•Observe the Limb:
Check the distal limb’s color, temperature, and capillary refill.
•Patient Feedback:
Monitor for signs of discomfort such as pain or numbness.
