Description

Technical Field

[0001] The utility model belongs to the technical field of hemostasis, and in particular relates to a radial artery puncture compression hemostasis bracelet. Background Art

[0002] The radial artery is the most commonly used site for arterial puncture. The radial artery at the wrist is in the longitudinal groove between the radial flexor carpi tendon and the lower end of the radius. The radial artery pulsation can be felt above and below the radial styloid process. Because this artery is superficial and relatively fixed, puncture and catheterization are relatively easy.

[0003] After radial artery puncture, compression is required to stop bleeding. The time for compression to stop bleeding is generally 10-15 minutes, mainly to avoid subcutaneous congestion after arterial puncture. Due to the high arterial pressure, arterial puncture will cause local bleeding and swelling, so compression to stop bleeding is necessary in time.

[0004] Manual compression hemostasis is currently the most commonly used clinical method. This method requires long-term compression hemostasis, which increases the workload of medical staff. With the development of medical equipment, manual methods are gradually replaced by mechanical compression. Mechanical compression includes pneumatic compression, clamp compression, and squeezing. However, overly tight compression by mechanical methods will cause blood flow in the hands to slow down and skin temperature to drop. Secondly, the compression body of mechanical compression is a fixed body that cannot be disassembled or replaced. After bleeding occurs at the puncture site, the compression body is easily infected, posing an infection risk. Summary of the invention

[0005] The utility model aims to design a radial artery puncture compression hemostasis bracelet, which can replace the soft pad at the compression block, gradually increase the pressure by twisting, and increase the long grooves on the inner surface of the bracelet to relieve squeezing and prevent the blood flow from slowing down.

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

[0007] The radial artery puncture compression hemostasis bracelet is characterized in that: the compression hemostasis bracelet comprises a first belt body, a second belt body and a hemostasis compression part. The first belt body and the second belt body are connected to form a bracelet, and the hemostasis compression part compresses and stops bleeding at the radial artery puncture site. The inner surfaces of the first belt body and the second belt body are longitudinally provided with a plurality of long grooves. The hemostasis compression part comprises a fixed body, and the fixed body is installed with an adjusting bolt. Screwing the bolt drives the compression plate to press against the puncture site, and a replaceable soft pad is installed at the compression plate.

[0008] Furthermore, an internal thread is provided in the middle of the fixing body, the external thread of the adjusting bolt cooperates with the internal thread, a knob is provided on the top of the adjusting bolt, and the extrusion pressure of the material is adjusted in a spiral manner to achieve a fine-tuning function.

[0009] Furthermore, a timer is installed on the knob, and the compression time is usually about 5 minutes, which can be used for countdown.

[0010] Furthermore, a limiting circular plate is provided at the bottom of the adjusting bolt, and a limiting circular plate groove is provided in the compression plate, so that the limiting circular plate of the adjusting bolt can rotate in the limiting circular plate groove.

[0011] Furthermore, a through hole is provided at the bottom of the compression plate, and an insert is provided at the top of the soft cushion, and the insert of the soft cushion can be inserted into the through hole.

[0012] Furthermore, the soft cushion is made of silicone material and has a frustum or hemisphere shape.

[0013] The above technical solution can achieve the following beneficial effects:

[0014] The plurality of longitudinal grooves on the first belt body and the second belt body of the utility model are conducive to blood flow when the wrist is squeezed by the bracelet, which can reduce the slowdown of blood flow in the hand and prevent the skin temperature from dropping.

[0015] The replaceable soft pad adopted by the utility model solves the infection problem. After the patient uses the compressor, the used soft pad is removed and a new soft pad is installed when it is used again, which meets the hospital infection risk control requirements.

[0016] The overall design of the structure of the utility model is reasonable. The knob bolt easily drives the compression plate to rotate, which will damage the puncture site. Therefore, a structure is designed in which the limiting circular plate can rotate in the limiting circular plate groove. The rotation of the knob bolt does not affect the compression plate, so that the compression plate can only move up and down but will not rotate. BRIEF DESCRIPTION OF THE DRAWINGS
