Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a femoral artery hemostat. Background Technology

[0002] A femoral artery hemostat is a medical device used to stop bleeding after femoral artery puncture. It works by applying pressure to the puncture site using an adjustable pressure balloon or mechanical compression structure. By applying appropriate pressure to the femoral artery puncture site, the blood flow at the ruptured blood vessel is slowed down and stopped, while promoting blood coagulation, thereby achieving the purpose of hemostasis.

[0003] Mechanical compression is generally superior to pneumatic compression. In conventional mechanical compression, a screw is rotated, causing it to move up and down, while a pressure block at the bottom of the screw presses against the puncture site. However, the pressure block also rotates during screw rotation, and although there is hemostatic cotton at the puncture site below the pressure block, it can still cause discomfort to the patient during the procedure. Furthermore, the screw can loosen, affecting the compression effect. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a femoral artery hemostat, which aims to solve the above technical problems.

[0005] The present invention adopts the following technical solution:

[0006] The femoral artery hemostat includes a front housing and a rear housing, which are integrally formed by a connecting part. A strap is connected to the middle of the connecting part. A compression device is installed inside the front housing, and a support device is installed at the bottom of the rear housing. The front housing has a vertically arranged square groove. The compression device includes a square block located in the square groove. A pressure rod is located at the bottom of the square block. After the pressure rod passes through the bottom of the front housing, a pressure block is provided. The square block has a screw hole extending downward into the pressure rod. A matching screw is screwed into the screw hole. A limit member is between the neck of the screw and the front housing. After the top of the screw passes through the front housing, a first handle is fixed thereon.

[0007] Furthermore, the front side of the front housing has a guide groove, and the front wall of the square block has a positioning rod that extends out of the guide groove. The end of the positioning rod is screwed with a second handle.

[0008] Furthermore, a baffle is located at the end of the positioning rod, outside the second handle.

[0009] Furthermore, a handle is provided between the front housing and the rear housing and above the connecting part.

[0010] Furthermore, the support device includes a support rod and an arc-shaped pressure plate located at the end of the support rod.

[0011] The beneficial effects of this utility model are as follows: In this structure, the top of the pressure rod has a square block, and the front housing has a matching square groove. By rotating the screw, the square block and the pressure rod as a whole move up and down along the square groove, thereby driving the pressure block to move up and down. During operation, the screw will not have any height change, and the pressure block will not rotate, which improves the patient-friendly experience. Moreover, in the preferred structure, the square block is further locked by the positioning rod and the second handle to prevent loosening between the screw and the screw hole, ensuring a continuous and stable compression effect.

[0015] 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.

[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0017] like Figure 1-3 As shown, the femoral artery hemostat provided in this embodiment includes a front housing 1 and a rear housing 2, which are integrally formed by a connecting part 3. A strap 4 is connected to the middle of the connecting part 3. A compression device 5 is installed inside the front housing 1, and a support device 6 is installed at the bottom of the rear housing 2. The front housing 1 has a vertically arranged square groove 11. The compression device 5 includes a square block 51 located in the square groove 11. A pressure rod 52 is located at the bottom of the square block 51. After the pressure rod 52 passes through the bottom of the front housing 1, a pressure block 53 is provided. The square block 51 has a screw hole 54 extending downward into the inside of the pressure rod 52. A matching screw 55 is screwed into the screw hole 54. A limit member 56 is between the neck of the screw 55 and the front housing 1. After the top of the screw 55 passes through the front housing 1, a first handle 57 is fixed thereon.

[0018] In use, the hemostat is strapped to the leg using the straps. The support device at the bottom of the rear housing contacts the leg. In the illustration, the support device 6 includes a support rod 61 and an arc-shaped pressure plate 62 located at the end of the support rod 61. The arc-shaped pressure plate 62 can adapt to the shape of the leg surface. The pressure block at the bottom of the compression device 5 contacts the puncture site (with hemostatic cotton in the middle). By tightening the straps 4, the compression device 5 presses against the puncture site, and then the pressure is further adjusted. During operation, the first handle 57 is rotated, which in turn drives the screw 55 to rotate. Since the screw 44, the square block 51, and the pressure rod 52 are internally threaded, the square block 51 and the pressure rod 52 can move up and down as a whole under the limitation of the western groove, and the pressure block at the bottom of the pressure rod does not rotate.

[0019] In this structure, the limiting member 56 at the neck of the screw 55 limits the screw to rotate only, not to move up and down. For example, the limiting member can be a disc fixed to the neck of the screw, with a matching annular groove at the top of the front housing. The disc is located within the annular groove and does not affect the rotation of the screw. Alternatively, the limiting member can be a bearing, providing rotational support.

[0020] As a preferred structure, the front housing 1 has a guide groove 12 on its front side, and the front wall of the square block 51 has a positioning rod 58 extending through the guide groove 12. A second handle 59 is screwed onto the end of the positioning rod 58. After the square block moves to the target position, the positioning rod indicates the height position, and the threaded section at the end of the positioning tube allows for further locking of the square block by tightening the second handle, creating pressure between the second handle and the front housing. This prevents loosening between the screw and the screw hole, ensuring a continuous and stable pressure effect. When pressure needs adjustment, the second handle is loosened first, and then the first handle is rotated. In the diagram, a baffle 510 is also located at the end of the positioning rod 58, outside the second handle 59, which limits the movement of the second handle 59, preventing it from detaching from the positioning rod when loosened.

[0021] Finally, a handle 7 is provided between the front housing 1 and the rear housing 2, above the connecting part 3. The front and rear housings are connected by the connecting part and the handle. This increases structural strength, making it less prone to deformation, and also facilitates the direct placement and removal of the hemostat.

[0022] 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.
