Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a locking compression hemostat. Background Technology
[0002] A compression hemostat achieves hemostasis by applying appropriate pressure to the bleeding site to stop blood flow and promote blood clotting. It typically consists of a compression component, a fixation device, and an adjustment device. The compression component acts directly on the bleeding site, the fixation device secures the hemostat to the body, and the adjustment device allows for adjustment of the pressure and position as needed.
[0003] Common compression hemostatic devices are wristband-type structures. The core structure of the adjustment device is a screw and a knob. The compression component is a pressure block located at the bottom of the screw. By rotating the knob, the height of the screw can be adjusted, thereby adjusting the pressure of the pressure block at the bottom on the wound, thus achieving the purpose of hemostasis.
[0004] Because conventional compression hemostats do not have a locking mechanism on their adjustment devices, and the screw is not unidirectional and does not have a locking function, there is a possibility of the pressure unexpectedly loosening, which reduces the hemostatic effect. Utility Model Content
[0005] In view of the above problems, the purpose of this utility model is to provide a locking compression hemostat, which aims to solve the above technical problems.
[0006] The present invention adopts the following technical solution:
[0007] The locking compression hemostat includes a housing with wing plates at both ends. The wing plates have long grooves for connecting a wristband. The housing contains a fixing sleeve with a square guide hole. A matching square pressure sleeve is located in the square guide hole. An adjusting tube is rotatably mounted on the top of the housing. The adjusting tube has threads on both the inside and outside. The lower middle part of the adjusting tube is screwed into the square pressure sleeve. A pressure tube is also screwed into the center of the adjusting tube. The bottom of the pressure tube contacts the inside of the square pressure sleeve.
[0008] Furthermore, the center of the square pressure sleeve is a circular hole, and the side wall of the circular hole has an internal thread. The adjusting tube is screwed into the circular hole of the square pressure sleeve.
[0009] Furthermore, the top of the regulating tube and the top of the pressure tube are both folded outward to form an operating ring, and the outer periphery of the operating ring has friction grooves.
[0010] Furthermore, the bottom of the pressure tube is not sealed.
[0011] Furthermore, the neck of the regulating tube has a ring plate, and the top of the fixing sleeve has a corresponding ring groove, with the ring plate located within the ring groove.
[0012] The beneficial effects of this utility model are as follows: The product structure is designed with an adjusting tube and a pressure tube. The pressure tube is screwed into the adjusting tube. By rotating the adjusting tube, the square pressure sleeve can move downward under the guidance of the square guide hole, thereby achieving pressure hemostasis on the wound. At the same time, while keeping the adjusting tube stationary, rotating the pressure tube allows the pressure tube to press against the bottom of the square pressure sleeve. In this way, the square pressure sleeve can be prevented from retracting due to the loosening of the adjusting tube, which would cause pressure loss and affect the hemostatic effect.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0019] like Figure 1-4 As shown, the locking compression hemostat provided in this embodiment includes a housing 1, with wing plates 2 at both ends of the housing 1. The wing plates 2 have long grooves 21 for connecting a wristband. The housing 1 has a fixing sleeve 3 inside, and a square guide hole 31 inside the fixing sleeve 3. A matching square pressure sleeve 4 is placed inside the square guide hole 31. An adjusting tube 5 is rotatably provided on the top of the housing 1. The adjusting tube 5 has threads on both the inside and outside. The lower middle part of the adjusting tube 5 is screwed into the square pressure sleeve 4. A pressure tube 6 is also screwed into the center of the adjusting tube 5. The bottom of the pressure tube 6 contacts the square pressure sleeve 4.
[0020] This product is used with a wristband 8. Both ends of the wristband connect to the long slots 21 on the box's wing plates. As shown in the illustration, one end of the wristband is fixed, while the other end is adjustable and can be secured with Velcro. Before use, first unscrew the pressure tube (unscrew it to a certain height; it does not need to be removed from the adjustment tube). Then, rotate the adjustment tube. Because the adjustment tube is threaded into the square pressure sleeve, and the square pressure sleeve mates with the square guide hole of the fixed sleeve, the square pressure sleeve moves upwards during the rotation of the adjustment tube until it reaches the highest position. In the illustration, the tops of the adjustment tube 5 and the pressure tube 6 are both folded outwards to form operating rings 7, and the outer circumference of the operating rings 7 has friction grooves to facilitate the rotation of the adjustment tube and the pressure tube.
[0021] Then, put on the wristband and fasten it, ensuring the square pressure sleeve is aligned with the puncture point (which usually has hemostatic cotton or similar material). Rotate the adjusting tube clockwise. Similarly, guided by the square guide hole, the square pressure sleeve moves downwards until it applies appropriate pressure to the puncture point. Next, continue rotating the pressure tube clockwise until the bottom of the pressure tube touches the bottom of the square pressure sleeve, thus locking it in place. Generally, because the adjusting tube applies pressure to the puncture point through the square pressure sleeve, there is some resistance to rotation. Therefore, you can directly twist the pressure tube inside the adjusting tube until it cannot be rotated any further, at which point the bottom of the pressure tube touches the bottom of the square pressure sleeve. Alternatively, you can hold the operating ring at the top of the adjusting tube 5 with one hand and rotate the operating ring at the top of the pressure tube with the other hand. In the illustration, the diameter of the operating ring at the top of the pressure tube is smaller than the diameter of the operating ring at the top of the adjusting tube, so the rotation will not interfere with each other.
[0022] In this embodiment, the center of the square pressure sleeve 4 is a circular hole with internal threads on the sidewall of the circular hole. The adjusting tube 5 is screwed into the circular hole of the square pressure sleeve 4. When the pressure tube rotates to its lowest position, it exerts pressure on the square pressure sleeve. At this point, the pressure tube and the adjusting tube are a threaded, integral structure. The adjusting tube can only rotate and cannot move up or down. For example, as shown in Figure 3, the neck of the adjusting tube 5 has a ring plate 51, and the top of the fixing sleeve 3 has a corresponding annular groove 32. The ring plate 51 is located within the annular groove 32, thus limiting its rotation. Therefore, even if the adjusting tube accidentally loosens and tends to rotate, the square pressure sleeve will not move upwards due to the limiting effect of the pressure tube. Ultimately, the adjusting tube, the pressure tube, and the square pressure sleeve form a single unit, preventing pressure release caused by reverse loosening.
[0023] Finally, the bottom of the pressure tube 6 is not closed. The pressure tube, the square pressure sleeve, the adjusting tube, etc. can all be made of transparent material, so that it can be seen from the outside whether there is any bleeding inside.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
