Abstract
Description
Technical Field
[0001] The utility model relates to the field of pneumatic tourniquets, and more specifically, to a pneumatic tourniquet. Background Art
[0002] Pneumatic tourniquet is a commonly used device in limb trauma surgery. It can significantly reduce intraoperative wound bleeding, thereby making the surgical field clear, easy to identify various tissues, and facilitating surgical operations.
[0003] After searching, no relevant patents were found.
[0004] When the existing pneumatic tourniquet is inflated, the gas will flow back when the pressure ball is released, causing gas leakage, resulting in the loss of gas in the airbag, resulting in poor bandaging effect. Therefore, it is necessary to add an inflation mechanism to help solve the above problem.
[0005] Therefore, a pneumatic tourniquet is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the above defects of the prior art, the utility model provides a pneumatic tourniquet to solve the problems raised in the above background technology.
[0007] To achieve the above object, the utility model provides the following technical solution: a pneumatic tourniquet, comprising a tourniquet body, one side of which is equipped with an inflation mechanism, the inflation mechanism comprising an airbag, and the airbag is arranged inside the tourniquet body.
[0008] A monitor housing is arranged above the tourniquet body, a display screen is fixedly mounted on one side above the monitor housing, and an operation button is arranged on the right side of the upper side of the monitor housing close to the display screen.
[0009] Preferably, an inflation tube is fixedly connected to one side of the airbag, a pressing ball is fixedly installed at one end of the inflation tube, the outer wall of the inflation tube is movably connected to a regulator shell, the inside of the regulator shell is movably connected to a regulating ball, and the other side of the airbag is fixedly connected to a deflation tube, and a soft plug is snap-fitted into the inside of the deflation tube.
[0010] Preferably, the adjusting ball and the adjusting device housing form an adjusting structure, and the adjusting device housing is narrow in the front and wide in the back.
[0011] Preferably, a left fixed wing is fixedly connected to one side of the tourniquet body, and a rough surface is sewn on one side of the surface of the left fixed wing.
[0012] Preferably, a right fixing wing is fixedly connected to the other side of the tourniquet body, and a hook surface is sewn on one side of the surface of the right fixing wing by needle and thread.
[0013] Preferably, the hook surface and the hairy surface form a fixed structure.
[0014] Preferably, a patch is provided on one side of the tourniquet body, and the patch is distributed parallel to the tourniquet body.
[0015] Technical effects and advantages of the utility model:
[0016] 1. Compared with the prior art, the pneumatic tourniquet, through the structural design of the inflation mechanism, can control the air intake speed by adjusting the position of the adjusting ball when the pneumatic tourniquet is in use. When the adjusting ball is adjusted to a wider position of the regulator housing, the inflation speed is faster. Conversely, when the adjusting ball is adjusted to a narrower position of the regulator housing, the inflation speed is slower. When inflation is not required, the adjusting ball is rolled to the narrowest end of the regulator housing so that the adjusting ball squeezes the inflation tube, thereby avoiding the phenomenon of gas backflow leakage.
[0017] 2. Compared with the prior art, the pneumatic tourniquet, through the structural design of the patch, monitor housing, display screen and operation button, can monitor the wound skin temperature, finger / toe pulsation and pulse oxygen reading through the patch when the pneumatic tourniquet is used, and can display the cuff pressure value in real time and record the waveform through the monitor and display screen. It can also record the duration of inflation, the number and time of relaxation intervals, and control its function options through the operation button. BRIEF DESCRIPTION OF THE DRAWINGS
