Surgical Tourniquet System

Working principle: Through controlling air pressure in hemostasia cuffs, inflatable cuffs can compress limbs, and then occlude blood flow, so that bleeding can be stopped.

Main composition: Host machine, extension airway tube, and hemostasia cuffs.

Working condition

Power supply: 220 V ± 22 V, 50 Hz ± 1 Hz

Environment temperature: 5℃ - 40℃

Relative humidity: 30% - 70%

Atmospheric pressure: 700 hPa – 1060 hPa

Input power: 18 VA


Storage and transport condition

Environment temperature: -10℃ - 40 ℃

Relative humidity: ≤93%

Atmospheric pressure: 500 hPa – 1060 hPa

Working pressure

Pressure set: 3 kPa - 100 kPa; Step value: 1 kPa; Tolerance: ± 2 kPa

Working time

Time set: 1 min - 600 mins; Step value: 1 min; Tolerance: ± 3 s

Memory function

Memorize the parameters set in last surgery automatically.

Voice prompt function

a) Five "Di-di-di" alarms remind operators at 10 mins, 5 mins and 1 min before the surgery completed.

b) Continual "di" reminds operators the completion at the end of the surgery.

c) In case air pressure in hemostasia cuff exceeds ± 5 kPa of the set value over 2 mins, continual "di" reminds operators.

Insurance function

a) Ladderlike deflation: Deflate ladderlikely at the end of the surgery or on pressing “Deflation” button, in order to prevent sudden heart and brain ischemia

b) Pressure maintenance in power failure: Machine can maintain the pressure in hemostasia cuffs even if sudden power off, so as to go on surgery smoothly and ensure patients’ safety.

Automatic compensation function

Detect air pressure in hemostasia cuffs in real time while working, and adjust the over-pressure and under-pressure resulted from squeezing cuffs, so as to ensure stable pressure value.


Package, storage and transport

Adopt carton for transport package. Package carton includes rain-proof set and soft pad. Packed machine should be stored in room-temperature, dry, no corrosive gas and good ventilation rooms. General vehicles are available. Prevent severe vibration, collision and the rain, and avoid exposure in transport.
