Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a pneumatic brachial artery hemostatic compressor. Background Technology
[0002] Brachial artery puncture interventional surgery has become a routine procedure for the diagnosis and treatment of cardiovascular and cerebrovascular diseases. Effective hemostasis at the puncture site after the procedure is crucial to avoiding complications such as hematoma and pseudoaneurysm. Currently, commonly used hemostasis methods in clinical practice include manual compression, mechanical compression devices (such as radial artery hemostats), and sandbag fixation. Traditional local compression devices only apply local pressure to the joint, but the elbow joint can still flex and extend, leading to changes in the compression point and affecting the hemostasis effect. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a pneumatic brachial artery hemostatic compressor.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic brachial artery hemostatic compressor, comprising: an air cushion, which has a rectangular structure when unfolded, for covering the upper and lower arm regions of the patient's arm, and a compression part is provided in the middle region of the air cushion corresponding to the position of the brachial artery, with a distance between the front end of the compression part and the front end of the air cushion; a connecting strap, fixed to one side edge of the air cushion along the circumferential direction of the air cushion; a pressing airbag, connected to the air cushion through an air tube, for inflating the air cushion to compress the brachial artery; a pressure gauge, set on the surface of the air cushion, for real-time monitoring of the internal pressure of the air cushion; and an air valve, set between the air tube and the pressing airbag, for controlling the air pressure of the inflated air cushion; wherein, after inflation, the air cushion compresses the brachial artery by covering the upper and lower arms, and the connecting strap is fixed around the arm in a circumferential direction to restrict elbow flexion; after the compression part is inflated, the air cushion naturally forms an operating area at the front end of the lower arm for the fingers to enter.
[0005] As a preferred technical solution of this utility model, the front and back sides of the connecting strap are respectively provided with a hook and loop surface and a hook and loop stud surface, which are used to fix the strap around the arm by the hook and loop surface and the hook and loop stud surface.
[0006] As a preferred embodiment of this utility model, the surface of the airbag is provided with a first connector and a second connector, which are respectively connected to the air tube and the pressure gauge.
[0007] As a preferred embodiment of this utility model, the air valve is a knob-type regulating valve, used for manual control of inflation and depressurization.
[0008] As a preferred technical solution of this utility model, the air cushion is made of transparent TPU material.
[0009] Compared with the prior art, the beneficial effects of this utility model are: the compression part and the front end of the air cushion are left with a distance, and the operating area is automatically formed after inflation. Through the coordinated design of the air cushion and the operating area, the brachial artery can be compressed, and the fingers can be inserted for operation. Moreover, part of the air cushion is located on the upper arm and the other part is located on the lower arm, which can avoid elbow bending and keep the arm in a fixed position. When inflated, the compression part accurately corresponds to the brachial artery position. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] like Figure 1-4The illustrated pneumatic brachial artery compression device includes: an air cushion 1, which unfolds into a rectangular structure to cover the upper and lower arm regions of the patient's arm. A compression section 2 is located in the middle of the air cushion 1 corresponding to the brachial artery, with a gap between the front end of the compression section 2 and the front end of the air cushion 1 (to create an operating area 8 during inflation, providing space for finger insertion); a connecting strap 3, fixed to one edge of the air cushion 1 along its circumferential direction; a compression bladder 4, connected to the air cushion 1 via an air tube 5, used to inflate the air cushion 1 to compress the brachial artery with the compression section 2; a pressure gauge 6, located on the surface of the air cushion 1, used to monitor the internal pressure of the air cushion 1 in real time; and an air valve 7, located between the air tube 5 and the compression bladder 4, used to control the inflation of the air cushion 1. The pressure is maintained; wherein, after inflation, the air cushion 1 compresses the brachial artery by covering the upper and lower arms, and the connecting strap 3 is fixed around the arm in a circumferential manner to restrict elbow flexion; after the compression part 2 is inflated, the air cushion 1 naturally forms an operating area 8 at the front end of the lower arm (there is a gap between the inner arm and the outer arm of the palm in the operating area 8, which allows the fingers to insert the tube). In this embodiment, the air cushion 1 is made of transparent TPU material; the compression part 2 expands when the air cushion 1 is inflated, or the compression part 2 itself is made of flexible silicone. It only compresses the brachial artery when the air cushion 1 is inflated. It should be noted that before using the hemostatic compression device, one or more layers of gauze need to be placed at the brachial artery in advance. The compression part 2 acts on the gauze to indirectly compress the brachial artery, rather than directly contacting the arm.
[0018] The compression part 2 and the front end of the air cushion 1 are separated by one end. After inflation, the operating area 8 is automatically formed. Through the coordinated design of the air cushion 1 and the operating area 8, the brachial artery can be compressed, and the fingers can be inserted for operation. Moreover, part of the air cushion 1 is located on the upper arm and the other part is located on the lower arm, which can prevent the elbow joint from bending and keep the arm in a fixed position. When inflated, the compression part 2 is precisely aligned with the brachial artery position.
[0019] The connecting strap 3 has a hook and loop fastener 9 and a hook and loop fastener 10 on its front and back sides, respectively, for wrapping around the arm and fixing it by the hook and loop fastener 9 and the hook and loop fastener 10. In this embodiment, an elastic band can be partially provided at the end of the connecting strap 3 that is connected to the air cushion 1.
[0020] The surface of the airbag is provided with a first connector 11 and a second connector 12, which are respectively connected to the air tube 5 and the pressure gauge 6.
[0021] The air valve 7 is a knob-type regulating valve 13, used for manual control of inflation and depressurization. The knob-type regulating valve 13 is existing technology and will not be described in detail in this application. It is the same as the inflation principle on the market. Alternatively, the air valve 7 can also be a one-way valve, allowing the airbag to flow unidirectionally towards the air cushion 1. At the same time, a pressure relief valve is added between the air valve 7 and the air cushion 1, so that the air can be released through the pressure relief valve after use.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
