Description

Arteriovenous fixed-point compression tourniquet

technical field

The utility model relates to a medical device for hemostasis, in particular to an arteriovenous fixed-point pressurized tourniquet.

Background technique

Generally, the total blood volume of an adult is about 4000 milliliters. If too much blood is lost in a short period of time, the tissues and organs will be in a state of severe ischemia, which will soon be life-threatening. Hemostasis is a basic operation that is often encountered and needs to be dealt with immediately during surgical operations. Whether hemostasis is timely and appropriate is crucial to the success of surgical operations. Compression hemostasis is the most commonly used method of hemostasis in surgery. Its principle is to shrink or close the vascular opening with a certain pressure, and then due to the slowing down of blood flow, platelets, fibrin, and red blood cells can quickly form thrombus to stop bleeding. Hemostasis requires pressurization of damaged blood vessels, and pressure on undamaged blood vessels may cause a series of complications such as numbness, pain, wound bleeding, and even necrosis of the affected limb. Some complications can be corrected by appropriate measures. Others cause irreparable permanent disabilities and bring undue pain to patients. During the surgeon's operation, the doctor often needs to press the patient's arteriovenous bleeding port with his hands, and the time required generally lasts for one to twenty minutes, which not only wastes precious medical time, but also often feels tired to the doctor. Hand pressing has uneven and unstable pressing force, which affects the hemostatic effect.

Contents of the invention

The purpose of the utility model is to accurately and stably pressurize and stop bleeding at the damaged point of blood vessels, and provide a new technical proposal of a fixed-point pressurized tourniquet for arteries and veins.

The technical scheme of the utility model: an arteriovenous fixed-point pressurized tourniquet, which is provided with a pressurizing device on the fixing device, is characterized in that the fixing device is to connect fixing belts at both ends of the tourniquet base, and the The pressurizing device is to connect the supporting seat on the base of the tourniquet, the center of the supporting seat is provided with a hole, and the side of the supporting seat is provided with a pressure groove communicating with the hole, and the gap in the hole of the supporting seat is matched to connect the sliding shaft, and the sliding shaft The bottom is fixedly connected to the hemostasis block, and the top of the sliding shaft is fixedly connected to the pressurized block. The pressurized block fits with the pressurized groove, and the locking device is connected to the pressurized device. The locking device is fixedly connected to the other end of the pressurized block. The small shaft is rotatably connected with an eccentric locking block, and the eccentric locking block is provided with a locking handle.

The tourniquet is a magic band.

The eccentric distance e of the eccentric locking block (4) is 1-5 mm.

The utility model relates to a compression hemostatic device, which is composed of a fixing device, a pressurizing device and a locking device. The device is fixed above the position where hemostasis is required through the fixing belt, and the pressure of the fixing belt on the fixing place is small, and the blood flow at the fixing place will not be affected. Align the hemostasis sheet with the position where hemostasis is needed, move the pressurized block up and down along the sliding groove, adjust the sliding shaft to drive the hemostatic sheet to expand and contract, realize the pressure adjustment of the hemostatic block to the place where hemostasis is required, and rotate the eccentric locking block Lock the handle so that the eccentric locking block locks the position of the hemostatic block on the support seat of the hemostatic block to achieve pressurization of the damaged blood vessels, and only the damaged blood vessels in the human body under the hemostatic pressure sheet are under pressure. Hemostasis, to achieve accurate hemostasis by pressurizing blood vessel damage points. The utility model has a compact structure and a regular shape. When the patient uses it, it is not suitable for collision to cause the compression to fail. The pressure is balanced and stable. The pressure is controllable and adjustable. The pressure can be stable and long-lasting, and the blood flow of the body under the fixed belt that does not need hemostasis will not be affected. The fixing belt of the present utility model should adopt magic belt, and magic belt has another name called sticky buckle belt, is a kind of connecting auxiliary material commonly used on the clothes, divides male and female two sides: one side is soft fiber, and the other side is the elastic fiber with barb . The male and the female are interlocked. Under the condition of a certain horizontal force, the elastic hook is straightened, loosened from the pile loop and opened, and the original hook shape is naturally restored after the external force is removed. The magic belt is used to fix the position flexibly and to adjust easily. The utility model can free doctors from the simple and repeated work of pressing to stop bleeding, and the pressing is stable and reliable, and the effect of stopping bleeding is improved. The utility model has the advantages of simple structure, reasonable design, compact structure, low production cost, simple operation, safe and reliable compression, adjustable and controllable compression force, stable structure and long service life, and can be widely used in arteriovenous hemostasis in surgical operations And arteriovenous hemostasis in trauma.
