Description

Technical Field

[0001] The utility model relates to the technical field of hemostasis, and more specifically to a peripheral blood collection and compression hemostasis device. Background Art

[0002] Peripheral blood collection is a common medical operation, mainly used to obtain blood samples from patients for various tests and analyses. This process is crucial for diagnosis, monitoring disease status, and evaluating treatment effects. A compression hemostasis device is a medical device used to stop bleeding after blood collection or intravenous injection. After peripheral blood collection, a compression hemostasis device is generally required to stop bleeding.

[0003] Publication No. CN215129462U discloses a pressurized hemostatic patch for venous puncture. After a nurse punctures a patient's vein, the nurse needs to use a hemostatic patch to stop bleeding at the puncture site. However, most traditional hemostatic patches for venous puncture are pressed manually, and the manual pressing method cannot keep the force relatively stable, which will cause extreme discomfort to the patient and seriously aggravate the patient's pain. Through the cooperation of an elastic rope, a movable plate, an extrusion rod and a spring, the nurse sticks the hemostatic patch to the puncture site of the patient's body through an adhesive layer. While sticking the hemostatic patch, the elastic rope is stretched. The elastic rebound of the elastic rope can drive the movable plate downward to compress the spring. The elastic rebound of the spring can reversely squeeze the pressure plate, thereby pressurizing the hemostatic pad, and then pressurizing the patient's puncture site, thereby improving the hemostatic effect of the hemostatic patch and solving the problem that the traditional hemostatic patch for venous puncture cannot pressurize the hemostatic patch independently according to the needs of the patient.

[0004] Although the hemostatic patch can provide stable pressure to stop bleeding during use, it is inconvenient to adjust the pressure of the hemostatic patch when used by different patients or when the amount of bleeding at the blood drawing point is different. Too low pressure may easily lead to poor hemostasis effect, while too high pressure may easily cause discomfort to the patient. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, the utility model provides a peripheral blood collection and compression hemostasis device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A peripheral blood collection and compression hemostasis device comprises two sterile connecting belts, the top surfaces of the two sterile connecting belts are provided with a plurality of vent holes, and an adjusting hemostasis mechanism is arranged between the two sterile connecting belts;

[0008] The adjustable hemostasis mechanism includes a fixed sleeve, which is fixed between two sterile connecting belts. A threaded hole is provided on the top surface of the fixed sleeve, a threaded column is arranged inside the threaded hole, a fixed knob is fixedly connected to the top of the threaded column, a movable shell is arranged at the bottom of the fixed knob, a connecting block is fixedly connected between the fixed knob and the movable shell, and sterile cotton is arranged inside the movable shell.

[0009] Preferably, the bottom of the threaded column passes through the fixing sleeve and extends into the threaded hole, and the threaded column is threadedly connected to the threaded hole.

[0010] Preferably, the movable shell is slidably connected to the inner wall of the fixed sleeve, and the sterile cotton is slidably connected to the inner wall of the movable shell.

[0011] Preferably, the bottom of the two sterile connecting tapes are both provided with double-sided adhesive tape, and the bottom of the double-sided adhesive tape is provided with a non-stick paper layer.

[0012] Preferably, an alcohol storage film is fixedly connected to the top of the inner wall of the movable shell, and the alcohol storage film is arranged on the top of the sterile cotton.

[0013] Preferably, connection grooves are provided on both side surfaces of the inner wall of the movable housing, an elastic member is fixedly connected to the inner wall of the connection groove, and one end of the elastic member is fixedly connected to one side of the sterile cotton.

[0014] Preferably, the double-sided adhesive is made of polyester film, and the non-stick paper layer is made of polyethylene.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting an adjustable hemostasis mechanism, the sterile cotton is used to press the hemostasis point to stop bleeding, and by rotating the fixed knob, the fixed knob drives the threaded column to rotate, so that the threaded column moves inside the threaded hole, thereby driving the moving shell to move through the connecting block, so that the pressure between the sterile cotton and the skin is adjusted. Compared with the prior art, the pressure of the sterile cotton can be adjusted through the adjustment mechanism, so that the sterile cotton can achieve a sufficient hemostasis effect without causing discomfort to the patient. It has higher applicability and will not cause discomfort to the patient due to excessive pressing pressure. At the same time, both hands are freed, and there is no need to manually press for a long time to stop bleeding;

[0017] 2. By pressing the fixed knob and the fixed sleeve, the sterile cotton and the movable shell can squeeze the alcohol storage film, so that the elastic part produces elastic deformation. When the alcohol storage film breaks and the alcohol penetrates into the sterile cotton, the elastic part will rebound and restore the sterile cotton to its original position. The alcohol will be squeezed out when used, which can effectively avoid the problem of alcohol volatilization. The alcohol is always in a sealed state before use to prevent alcohol volatilization from affecting the hemostatic effect. BRIEF DESCRIPTION OF THE DRAWINGS
