Automatic Pneumatic Tourniquet

The automatic pneumatic tourniquet is a specialized hemostatic device commonly used in orthopedic limb surgeries. It functions by applying pneumatic pressure to the base of the limb to occlude blood flow, thereby significantly reducing bleeding at the surgical site and providing a clearer operative field.

Basic Structure and Hemostasis Principle

Core Components: Main unit, pneumatic tourniquet cuff, and power cord.
Operating Mechanism:A microcomputer precisely controls air pressure; the cuff compresses the limb to block blood flow.
Dual-channel Models:Capable of alternating inflation to minimize neuromuscular damage during prolonged use.

Primary Clinical Applications

Orthopedic Limb Surgeries:Fracture reduction and internal fixation, arthroscopy, and amputation.
Soft Tissue Surgeries: Excision of limb masses or cysts; exploration and repair of nerves, tendons, and blood vessels.
Other Procedures: Bone grafting and replantation of severed limbs or digits.

Strict Contraindications

Contaminated wounds older than 6 hours; skin damage or edema at the application site.
Patients with severe hypertension, thromboangiitis obliterans, venous thrombosis, or severe arteriosclerosis.
Use on patients with blood disorders requires careful clinical assessment.

Routine Maintenance

Avoid direct contact with water; disconnect the power supply before cleaning.
Inspect the cuff and tubing for damage or air leaks prior to each use.
When not in use for extended periods, unplug the device and store it in a dry, dust-free environment away from direct sunlight.
