Description

A kind of novel radial artery tourniquet

Technical field

This utility model relates to a kind of medical supplies, especially a kind of novel radial artery tourniquet.

Background technology

After trans-radial coronary arteriography, needing that patient's wrist place is left to wound stops blooding, this just need to use tourniquet wound is carried out to hemostasis by compression, use traditional radial artery tourniquet, in the process of compressing, thereby medical personnel need certain interval of time just to remove to unscrew a briquetting reduces the compressing of briquetting to blood vessel gradually, in preventing collapsing blood, reduce the generation of ecchymosis, use traditional radial artery tourniquet, because need medical personnel's on the scene adjusting in good time, the restriction of patient's active receiving, medical personnel's workload is large simultaneously, the ceaselessly time of the seeing line item of going forward side by side, particularly when patient is more, medical personnel easily make mistakes in unrest, in addition medical care in the time unscrewing completely by rule of thumb, accurate not.

Utility model content

This utility model is intended to address the above problem, and a kind of novel radial artery tourniquet is provided, it can automatically reduce gradually briquetting to the compressing of blood vessel without medical personnel, patient's activity is unrestricted, simultaneously can accelerate blood coagulation, its technical scheme adopting is as follows:

A kind of novel radial artery tourniquet, is characterized in that, comprising: mainboard, fixing band, putting part, rubber cushion blocks, motor, the main gear that drives, can clutch gear, pull bar, limiting plate, draw ring, from driving gear, bull stick, hands handle, rotating cylinder, depression bar, briquetting, cooling paster, intervalometer and the control panel that timer parameter can be set, described fixing band is provided with VELCRO, described putting part, rubber cushion blocks and motor all with mainboard Joint, described master drives gear and is connected with the rotating shaft of motor, described can clutch gear with main drive that gear is meshed and with the bottom Joint of pull bar, described limiting plate and pull bar Joint, described draw ring is connected with limiting plate, described pull bar passes putting part and is slidably connected with putting part, on described pull bar, be set with spring, described spring can clutch gear and the inwall of putting part between, described from drive gear with can clutch gear be meshed and with bull stick and rotating cylinder Joint, described handle and bull stick detachable connection, described rotating cylinder and mainboard are rotationally connected, and described depression bar is threaded with rotating cylinder, described depression bar bottom and briquetting Joint, described cooling paster is fixed on briquetting bottom surface, and described intervalometer is electrically connected with motor.

On technique scheme basis, also comprise buzzer, described buzzer is electrically connected with intervalometer.

On technique scheme basis, described draw ring is rotationally connected by hinge and limiting plate.

On technique scheme basis, the cross section of described bull stick is square.

On technique scheme basis, described briquetting is made up of the hard plastic bed of material on top and the soft rubber layer of lower floor.

The utlity model has following advantage: can automatically reduce gradually briquetting to the compressing of blood vessel without medical personnel, patient's activity is unrestricted, simultaneously can accelerate blood coagulation.

Detailed description of the invention

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As depicted in figs. 1 and 2, the novel radial artery tourniquet of the one of the present embodiment, is characterized in that, comprising: mainboard 1, fixing band 2, putting part 3, rubber cushion blocks 4, motor 32, the main gear 29 that drives, can clutch gear 28, pull bar 26, limiting plate 25, draw ring 23, from driving gear 22, bull stick 21, handle 20, rotating cylinder 40, depression bar 41, briquetting, cooling paster 12, intervalometer 31 and the control panel 34 that timer parameter can be set, described fixing band 2 is provided with VELCRO, described putting part 3, rubber cushion blocks 4 and motor 32 all with mainboard 1 Joint, described master drives gear 29 and is connected with the rotating shaft of motor 32, described can clutch gear 28 with main drive that gear 29 is meshed and with the bottom Joint of pull bar 26, described limiting plate 25 and pull bar 26 Joints, described draw ring 23 is connected with limiting plate 25, described pull bar 26 passes putting part 3 and is slidably connected with putting part 3, on described pull bar 26, be set with spring 27, described spring 27 can clutch gear 28 and the inwall of putting part 3 between, described from drive gear 22 with can clutch gear 28 be meshed and with bull stick 21 and rotating cylinder 40 Joints, described handle 20 and bull stick 21 detachable connections, described rotating cylinder 40 is rotationally connected with mainboard 1, described depression bar 41 is threaded with rotating cylinder 40, described depression bar 41 bottoms and briquetting Joint, described cooling paster 12 is fixed on briquetting bottom surface, it should be noted that the effect because of low temperature with acceleration blood coagulation herein, therefore cooling paster 12 can accelerate blood coagulation, described intervalometer 31 is electrically connected with motor 32.

Preferably, also comprise buzzer 34, described buzzer 34 is electrically connected with intervalometer 31.
