Description

Technical Field

[0001] The utility model relates to the technical field of hemostats, in particular to an arterial hemostat with a venous indwelling needle protection device. Background Art

[0002] Arterial puncture is a common clinical procedure used to obtain arterial blood samples or monitor arterial blood pressure. When performing arterial puncture, doctors need to follow strict operating specifications to reduce the occurrence of complications. Since arteries are the main channels for blood flow, if arterial damage causes bleeding, it will cause a large amount of blood loss and endanger life. Therefore, it is necessary to compress the artery to quickly control bleeding and prevent further loss. When blood accumulates inside the tissue or body cavity, it will compress the surrounding tissue, causing tissue ischemia and hypoxia, and in severe cases, it may cause tissue necrosis.

[0003] During the anesthesia process, the anesthesiologist often places the arterial and venous catheters in parallel when performing arterial puncture due to the limitation of the surgical site or body position of the patient. When the arterial puncture fails or the arterial catheter needs to be removed at the end of the operation, using the existing arterial hemostat to press the arterial puncture point will not only cause skin or tissue compression to the patient due to the compression of the venous catheter, but also cause the vein to be blocked or blocked, affecting the infusion of drugs, thus endangering the patient's life; if the conventional method is used, the arterial puncture point is manually pressed with gauze or cotton balls, which is not only time-consuming and labor-intensive, but also affects the progress of clinical nursing work. Therefore, the utility model provides an arterial hemostat with a venous catheter protection device to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0013] Furthermore, the second support spring is fixedly connected between the sliding block and the inner control groove, a plurality of the second support springs are provided, and the pressing block is fixedly provided at one end of the sliding block away from the second support spring;

[0014] Through the above technical solution, the second support spring can always push the sliding block toward one end of the inner control groove, so that the positioning top cone can always remain exposed from the upper fixing plate.

[0015] Furthermore, a plurality of the positioning top cones are slidably disposed at the inner upper end of the sliding block, and a plurality of the first supporting springs are respectively fixedly connected between the plurality of the positioning top cones and the inner part of the sliding block;

[0016] Through the above technical solution, the positioning top cone can be extended and retracted inside the sliding block. When the positioning top cone is extended, it will be stuck in the inside of the buckle hemostatic bandage, thereby fixing the position of the adjustment mechanism. When the positioning top cone is retracted, the adjustment mechanism and the buckle hemostatic bandage are released, which facilitates the adjustment of the position.

[0017] Furthermore, the upper fixing plate is fixedly arranged at the upper end of the inner fixing frame, and the plurality of positioning top cones are all arranged through the upper end of the upper fixing plate;

[0018] Through the above technical solution, it is achieved that the upper end of the upper fixed plate is extended in the normal state, and when the pressing block is pressed, the pressing block will drive the sliding block to move, so that the opening of the upper fixed plate and the top of the positioning top cone are misaligned, and then the positioning top cone will be pressed into the lower end of the upper fixed plate.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes an arterial hemostat with a venous indwelling needle protection device. An absorbent gelatin sponge and a venous indwelling needle protection frame are arranged on the buckle hemostatic bandage. When performing arterial puncture, the use of the absorbent gelatin sponge can quickly and effectively press the artery to achieve the hemostatic function. At the same time, the built-in venous indwelling needle protection frame can be stably supported in a specific position to ensure that the vein is properly protected. This improved design not only greatly reduces the operation steps and the required effort, but also significantly improves the overall use effect of the hemostat.

[0021] 2. The utility model proposes an arterial hemostat with a venous indwelling needle protection device. The venous indwelling needle protection frame arranged inside can be firmly embedded in the buckle hemostatic bandage when the positioning top cone is extended, which significantly enhances the fixing effect. In addition, the protection frame is equipped with an adjustment mechanism and can be accurately adjusted to the desired position. During the adjustment process, by applying pressure to the pressing block, the sliding block is driven to move smoothly, so that the opening of the upper fixing plate is misaligned with the top of the positioning top cone, and then the positioning top cone is lightly pressed into the lower end of the upper fixing plate, thereby releasing the fixation between the adjustment mechanism and the buckle hemostatic bandage, which provides convenience for flexible adjustment of the position.
