Description

Blood-permeable tourniquet

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to tourniquet is passed through to blood.

Background

An arteriovenous fistula is an operation treatment for arteriovenous fistula short circuit, the method is to open an outer side hole on an artery, the far end of a vein is connected with the outer side hole of the artery, the artery is divided into two parts, one part of the two parts is continuously supplied to a palm, the other part of the two parts directly flows back from the vein through a broken end of the vein to arterialize the vein, when a patient has thorough blood, blood is drained from the artery end, the blood flows back from the vein end, when dialysis is finished, a puncture point needs to be pricked by a tourniquet, the tourniquet is loosened every 30min, 1h and 2h, and the tourniquet is gradually loosened to achieve the aim of hemostasis.

At present tourniquet commonly used adopts the bandage to cover the point of puncture, and the bandage passes through the magic and pastes fixedly, and during the use, the pressure of point of puncture relies on patient's subjective judgement or nurse's experience to judge completely, and the too loose of tourniquet tie can not reach hemostasis purpose, and the tension probably causes closed fistula again, and the patient can't dialyse once more after closing the fistula, needs the operation to make the internal fistula clear again, and the elasticity operating procedure of tourniquet is complicated simultaneously, and the process of elasticity, patient need other people to assist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tourniquet is passed through to blood to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model adopts the following technical scheme: the blood permeable tourniquet comprises a tourniquet body, wherein two ends of the tourniquet body are fixed through magic tapes, a hemostasis block is arranged in the middle of the tourniquet body, a hemostasis layer is adhered to one side, corresponding to a wound of a patient, of the hemostasis block, a plurality of pressure sensors are arranged on one side, close to the hemostasis layer, of the hemostasis block, a display screen is arranged on one side, far away from the wound of the patient, of the hemostasis block, and the display screen is connected with the pressure sensors;

the tourniquet has the intermediate layer, the intermediate layer internal fixation has a plurality of oppression gasbags, the mouth that loses heart of a plurality of oppression gasbags switch on through disappointing pipeline, just the mouth that loses heart of disappointing pipeline extends to the tourniquet is outside, it is equipped with the snuffle valve to lose heart, the inflation inlet of a plurality of oppression gasbags switch on through the gas tube, the inlet end of gas tube extends to tourniquet external connection has the gas bag.

The utility model discloses improve on the basis of original tourniquet, through aerifing, exhausting to the oppression gasbag and adjust the elasticity of tourniquet, make the pressure size of puncture point visual through the pressure sensors who adds, display screen simultaneously, be convenient for adjust the elasticity of tourniquet, do not need patient's subjective judgement or nurse's experience to judge simultaneously, the too loose of avoiding the tourniquet to prick can not reach hemostasis purpose, the drawback of closed fistula probably is caused again to the tension.

Preferably, the hemostatic layer is medical gauze.

Preferably, the air leakage pipeline and the air inflation pipeline are made of plastic hoses.

Preferably, the number of the pressure sensors is at least two, the pressure sensors are all connected with the controller, and the controller is connected with the display screen, so that the pressure detection of the puncture area is more accurate.

The utility model has the advantages that:

the utility model discloses a tourniquet is passed through to blood, the elasticity process is simple, and the patient can independently accomplish, does not need other people to assist, and the elasticity of tourniquet is through the monitoring of pressure sensors for the elasticity degree of puncture point is visual, does not need patient subjective judgement or nurse experience to judge, and the too loose of avoiding the tourniquet to tie reaches the hemostasis purpose, and the tension probably causes the drawback of closed fistula again.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the blood permeable tourniquet of the utility model comprises a tourniquet 1, two ends of the tourniquet are fixed by magic tapes 2, a hemostatic mass 3 is arranged in the middle of the tourniquet 1, a hemostatic layer 31 is adhered to the side of the hemostatic mass 3 corresponding to a wound of a patient, a plurality of pressure sensors 32 are arranged on the side of the hemostatic mass 3 close to the hemostatic layer 31, a display screen 33 is arranged on the side of the hemostatic mass 3 away from the wound of the patient, and the display screen 33 is connected with the pressure sensors 32;

tourniquet 1 has

intermediate layer

11, 11 internal fixation of intermediate layer has a plurality of oppression gasbags 12, a plurality of the disappointing mouth of oppressing gasbags 12 through disappointing pipeline switch-on, just the disappointing mouth of disappointing pipeline extends to 1 outside of tourniquet, disappointing mouthful and being equipped with the valve that loses heart, a plurality of inflation mouths of oppressing gasbags 12 through the inflation duct switch-on, the inlet end of inflation duct extends to 1 external connection in tourniquet has inflatable air bags 4.

Tourniquet 1 is divided into two by hemostatic mass 3, two sections tourniquets 1 are all fixed in the both sides of hemostasis piece 3, in use, twine tourniquet 1 on patient's arm, two sections tourniquets 1 are through the magic subsides closure, guarantee simultaneously that tourniquet 31 covers on patient's puncture point, pressure sensor 32 monitoring tourniquet 1 between tourniquet 31 and the hemostasis piece 3 this moment applys the pressure for the puncture point, the pressure value of pressure sensor 32 monitoring shows through display screen 33, supply patient or nurse to judge the elasticity of tourniquet 1, aerify oppression gasbag 12 through aerifing gasbag 4 when pressure is too little, thereby increase tourniquet 1 and apply the pressure for the puncture point, when too big or need relax tourniquet 1, release the gas in the oppression gasbag 12 through the release valve.

As a preferable scheme of the above embodiment, the hemostatic layer 31 is made of medical gauze.

As a preferable solution of the above embodiment, the air-release duct and the air-inflation duct are made of plastic hoses, so that the air-release duct and the air-inflation duct can be bent.
