Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, and more specifically to a novel brachial artery compression hemostat. Background Art
[0002] With the development of interventional cardiology, percutaneous coronary angiography / intervention has become a common clinical method for the diagnosis and treatment of coronary heart disease. The femoral artery, radial artery or brachial artery of the human body are the necessary access routes for interventional diagnosis and treatment. If the local compression or displacement after puncture or sheath removal is improper, it may cause complications such as bleeding, hematoma, arteriovenous fistula or pseudoaneurysm at the puncture site, which will lead to serious consequences if not discovered in time. In particular, the brachial artery access route, although not a commonly used interventional access in clinical practice, is still an important choice for interventional operations in extreme cases such as severe stenosis, occlusion, and twisting of the radial artery or femoral artery. On the other hand, during the compression and hemostasis of the brachial artery, the patient's elbow joint is more likely to bend and move, resulting in the displacement of the compression surface of the arterial compression hemostat. If the compression position is not adjusted in time, it is easy to cause a series of vascular complications such as bleeding and hematoma at the puncture site.
[0003] However, there is currently no mature compression hemostat specifically for the brachial artery. In clinical practice, a conventional radial artery compressor is used to compress the brachial artery puncture site. However, if the patient is obese and has relatively thick arms, it is difficult to use a radial artery compressor for hemostasis. In addition, most of the existing radial artery compressors are fixed to the puncture area by adhesive tape. If the compression site is not suitable, the tape must be torn off when the hemostat needs to be moved. The firmness of the torn tape will be greatly reduced when it is pasted again, which seriously affects the fixation effect. Furthermore, due to the large range of motion of the elbow joint, the compressor is easily displaced. Without a specially designed fixing device, the compression hemostasis effect is easily affected.

[0022] When using the brachial artery compression hemostat of the utility model, the patient's elbow joint can be placed in the elbow joint fixing cavity of the elbow joint protector, so that the first positioning part 11 is attached to one side of the patient's elbow joint. Taking the right arm elbow joint as an example, this side is the outside of the elbow joint, and the second positioning part 12 is attached to the other side of the patient's elbow joint (the inside of the elbow joint). The first ends of the first positioning part 11 and the second positioning part 12 are fixed to the elbow joint using the second connecting belt 14, and fixed by bonding the first Velcro 17 and the second Velcro 18. The second ends of the first positioning part 11 and the second positioning part 12 are fixed to the elbow joint using the third connecting belt 15, and fixed by bonding the third Velcro 19 and the fourth Velcro 20.

[0024] A joint hole 33 is provided at the bottom bend of the elbow joint protector 10. The joint hole 33 can reduce the restriction of the elbow joint protector 10 on the elbow joint and improve the adaptability of the elbow joint protector 10 to the elbow joint.
[0025] The elbow joint protector can be made of plastic, and its shape is adapted to the outer contour of the human elbow joint, so as to play a good role in fixing and positioning the elbow joint.
[0026] Specifically, Figure 3 As shown, the compressor 16 includes a base plate 21, a threaded hole 22 arranged in the middle of the base plate 21, a stud 23 passing through the threaded hole 22 and screwed to the threaded hole 22, a pressure plate 24 fixed to the first end of the stud 23, and a knob 25 fixed to the second end of the stud 23.
[0027] Preferably, in order to achieve a better compression effect, the pressing plate 24 is a disc-shaped pressing plate 24, and the bottom surface of the disc-shaped pressing plate 24 is provided with an elastic pad 26, and the elastic pad 26 gradually protrudes from the edge to the middle in a spherical arc shape. The shape of the elastic pad 26 is adapted to the anatomical shape of the brachial artery at the elbow joint, which is conducive to accurate hemostasis of the brachial artery, while ensuring the comfort and experience of the patient. The elastic pad 26 can be made of silicone, or other materials with suitable flexibility, and no excessive restrictions are made here.
[0028] To facilitate the sliding adjustment of the base plate 21 and the compressor 16 on the first connecting belt 13, a first strip hole is provided on the first side of the base plate 21 for the first connecting belt 13 to pass through, and a second strip hole is provided on the second side of the base plate 21 for the first connecting belt 13 to pass through.
