Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a timed blood flow blocking device capable of increasing the success rate of radial artery puncture. Background Art

[0002] The first step in the coronary angiography procedure is to complete radial artery puncture. After anesthesia, the puncture needle is used to explore the radial artery. The operator touches the approximate location of the patient's radial artery with the fingertips, and then performs the puncture. If the operator fails to touch the radial artery on the right hand of a regular patient, the patient's left hand may need to be changed for puncture. The strength of the radial artery pulse directly affects the success of the puncture and the duration of the entire operation.

[0003] Research has found that by tying the patient's arm with a sphygmomanometer, inflating it to a pressure higher than the systolic pressure for 5 minutes, and then deflation, the radial artery can be dilated, which is medically known as long-term occlusion of blood flow-mediated dilation. However, the existing non-automatic mercury sphygmomanometers require a doctor or nurse to inflate the sphygmomanometer to about 150mmhg, blocking the patient's blood flow. The sphygmomanometer is released after 5 minutes, which is a complicated procedure and strictly delays the entire diagnosis and treatment time, bringing redundant work to clinicians and nurses.

[0004] Therefore, the utility model proposes a timed blood flow blocking device that can increase the success rate of radial artery puncture, thereby achieving the purpose of blocking blood flow, thereby enhancing the radial artery pulsation, and greatly increasing the operator's probability of successful surgery. Utility Model Content

[0005] The utility model provides a timed blood flow blocking device which can increase the success rate of radial artery puncture, and solves the problems of consuming diagnosis and treatment time and bringing redundant work to doctors and nurses in the prior application.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A timed blood flow blocking device capable of increasing the success rate of radial artery puncture comprises a double-sided cuff-type inflation device, wherein the double-sided cuff-type inflation device comprises a first cuff airbag and a second cuff airbag, wherein the first cuff airbag and the second cuff airbag are connected via a first inflation pipe, and one end of the first inflation pipe is connected to an air balloon; a timing device is installed on the first cuff airbag.

[0008] Furthermore, the airbag is connected to the first ventilation duct via a second inflation duct.

[0009] Furthermore, a gas control valve is provided on the second inflation pipe.

[0010] Furthermore, the first inflation pipe includes two horizontally arranged inflation pipes, one ends of the two horizontal inflation pipes are connected and communicated with each other through a vertical inflation pipe, and the middle part of the vertical inflation pipe is communicated with the second inflation pipe.

[0011] Furthermore, the first inflation pipe and the second inflation pipe are hollow rubber tubes.

[0012] Furthermore, the timing device is a timing alarm clock.

[0013] The beneficial effects of the utility model are:

[0014] The utility model can use one air balloon to inflate two cuff air bags at the same time, which greatly increases the operator's probability of successful operation. If the conventional right-hand puncture fails, the surgical process allows the option of changing the left hand to perform the operation; the timing device can accurately calculate the time of blocking blood flow to prevent excessive compression from causing hallucinations in patients.

[0015] The utility model can increase the success rate of puncture, reduce the operation time, and reduce the workload of doctors and nurses. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values.
