Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a vein hemostatic clamp. BACKGROUND

[0002] The technology of vein hemostasis after intravenous infusion mainly involves the following aspects: 1) correct needle removal technique: when removing the intravenous infusion needle, gentle operation should be adopted to avoid additional damage to the blood vessel. Immediately after needle removal, a sterile dressing is used to press the puncture point, and the pressing is continued until the bleeding stops. 2) local compression: appropriate local compression can effectively stop bleeding. The pressing time is 3-5 minutes, and for patients with poor blood coagulation function, the pressing time may need to be extended. 3) Because the injection needle is inserted obliquely into the patient's skin and the vein, the puncture point visible on the epidermis does not coincide with the puncture point on the vein, and the actual pressing point is not at the epidermal puncture point but at the vein puncture point. 4) Under normal circumstances, the blood pressure of the vein is 0.5-1.2 kPa. In order to ensure that the pressing force is moderate, it cannot be too light or too heavy, so as to avoid affecting blood circulation or failing to effectively stop bleeding. In addition, after infusion, the nurse needs to closely observe whether there is abnormal bleeding, swelling, etc. at the puncture site, and if abnormalities are found, they should be treated in a timely manner. Most patients and their families are not professional medical staff and cannot fully understand and accurately grasp the essentials of local compression hemostasis, such as position, force, duration of continuous and stable compression, etc. According to many studies and clinical reports, the incidence of bleeding, exudation, swelling, etc. at the puncture site after intravenous infusion varies, and generally, the incidence of these complications is about 10% to 30%.

[0003] By using a special vein hemostasis device (hemostatic clamp), the nurse can find the accurate pressing position, the hemostatic clamp provides a constant pressing force, and the continuous and stable pressing time is controllable, so that the incidence of pressing failure can be reduced.

[0004] The hand back vein puncture point hemostatic clamp with the authorization announcement number CN202761359U is disclosed, and according to the specification and drawings, the scheme is to adopt the structure of handle, shaft and clamp arm, open and close the clamp arm by using the lever principle, and apply pressure to the hemostatic point. However, the device is mainly divided into large, medium and small sizes, and the main difference is that the length and arc of the clamp arm are different, that is, the position of the pressure block cannot be moved, and the compression point and support point of the hand are also fixed. Therefore, the adaptability of the product is not good enough, which increases the cost of production and manufacturing. SUMMARY
