Abstract

The utility model discloses a sleeve ribbon type pressure-limiting vein tourniquet which uses a sealed bag with 200 mm to 300 mm length and 30 mm to 50 mm width to be tied on the four limbs of the body, and the manual balloon inflation is used to engorge the superficial vein. The enwrapping force of the seal bag is limited to 70 mmHg by a pressure-limiting valve. The rapid decompression of the seal bag is completed by a knob type release valve. The utility model can make venous engorgement become absolutely reliable, convenient, and effective.

Description

Sleeve ribbon type presure-limiting vein tourniquet

The vein tourniquet is a kind of medical supplies.Venipuncture when being used for medical-therapeutic treatment of human body.With the shallow table venous of its ligation extremity proximal part, the compressing vein makes the shallow table venous engorgement of distal end, is beneficial to venipuncture.Tourniquet commonly used at present in the medical treatment all is a root rubber pipe.The technology of this root rubber pipe of ligation is simple on extremity, and can the degree of tightness that prick suitable, depend on the experience of user fully.Because reach the compressing vein, and do not oppress tremulous pulse, pressure must be suitably.Cross loose tension and all can influence puncture success rate.In addition, the degree of degree of tightness also is subjected to the influence of patient's body constitution and fat or thin situation.Rubber tube is inconvenient, incomplete as tourniquet in a word.

This utility model provides a kind of reliably vein tourniquet easily.The easy to perform that the venous engorgement operation is become, reliable and stable.

Operation principle of the present utility model and basic structure are as follows: the band made from a wide gummed cloth replaces original rubber tube, the long 300-400mm of this cuff, wide 30-50mm, a root rubber flexible pipe is equipped with in the end, the back side of cuff is stained with woven silk and colludes cover, and the other end is stained with a woven silk and colludes.Rubber hose links through a triple-use valve and a rubber balloon.During use, cuff is needed the hemostatic position around patient's (descend) limb of going up, can regulate easily that braided wires is colluded and silk colludes and overlaps the position of colluding with according to patient's bodily form size.Then, press balloon and in the sealing cuff, be pressed into air, make the inflation of sealing cuff, produce pressure to oppress shallow table vein.When the air pressure in the cuff reached 70mmHg, the triple-use valve automatically pressure limiting made pressure be no more than the bottom line of this human body artery systolic pressure, does not cause the tremulous pulse pressurized to be closed.At this moment, the vein distal end will flow into for the blood flow that comes in a steady stream owing to tremulous pulse, and venous return is obstructed and fill, and makes venipuncture become and be easy to that after puncturing successfully, the patient makes the air pressure of cuff release once the drain charge switch by triple-use valve at once.

Triple-use valve above-mentioned has following three effects: 1. when pressing balloon when cuff is inflated, it is a check valve, and air-flow is only flowed in cuff.2. automatically pressure limiting after pressure reaches 70mmHg in the cuff, it is a pressure limiting valve.3. when needing immediately air pressure to be released after puncturing successfully, it is a drain charge valve.

Accompanying drawing is the example of a cuff formula pressure limiting tourniquet.Among the figure: 1. the sealing band of gas 2. woven nylon yarns made of gummed cloth collude cover 3. woven nylon yarns and collude 4. rubber tubes, 5. triple-use valves, 6. rubber balloons

Claims

A kind of vein pressure limiting tourniquet is made up of the band of gas, rubber balloon, rubber tube, triple-use valve, it is characterized in that the Pneumatic pipe cleaner in the balloon is crossed triple-use valve, rubber tube enters the band of gas.
