Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a device for removing a postoperative hemostat. Background Technology

[0002] Compression hemostasis is a common nursing measure in cardiology after coronary angiography or other interventional procedures involving arterial punctures. It achieves hemostasis at the puncture site by compressing the artery. Compression hemostasis is also an important emergency treatment for arterial bleeding caused by other injuries. The simplest compression hemostatic device is a tourniquet, which is typically a single band with a loop or D-ring at one end. To use it, one end of the tourniquet is first wrapped around the limb being compressed, then passed through the loop and secured with a Velcro fastener, or one end is wrapped around and passed through the D-ring for fixation. This type of tourniquet requires the band to always be passed through the loop or D-ring during application, and it needs to be removed for disassembly, making it somewhat cumbersome to use. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient device for removing postoperative hemostatic devices.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: a device for removing a postoperative hemostat, comprising a belt body and quick-release heads connected to both ends of the belt body. The quick-release heads are composed of a first shell and a second shell joined together, and the two are magnetically attracted to each other. The opposing sides of the first shell and the second shell are both stepped surfaces, and mutually cooperating arc-shaped abutment ridges and abutment grooves are provided at the steps.

[0005] The first housing is provided with a length adjustment mechanism. One end of the belt enters through the inlet at the top of the first housing, passes around the length adjustment mechanism, and exits through the outlet at the bottom of the first housing. The other end of the belt is connected to the top of the second housing.

[0006] Preferably, a magnetic layer is provided on the lower part of the opposite side of the first shell and the second shell, and magnetic adsorption is formed through the magnetic layer.

[0007] Preferably, the length adjustment mechanism consists of a first rotating shaft and a second rotating shaft arranged side by side inside the first housing. The belt body is S-shaped and passes around the first rotating shaft and the second rotating shaft. An adjustment component is provided at the second rotating shaft to control the switching between a unidirectional rotation state and a free rotation state of the second rotating shaft.

[0008] Preferably, the second rotating shaft includes a shaft body and a square column. The shaft body has a square hole extending along its length at its center. One end of the square column passes through the square hole and is in sliding fit with it. A return spring is provided between the inner end of the square column and the bottom of the square hole. The shaft body and the opposite end of the square column are each provided with a pin, which passes through the first housing and is in rotational fit with it.

[0009] The adjustment assembly includes a ratchet fixedly mounted on a square post and a pawl fixedly mounted inside the first housing and cooperating with the ratchet; a pressing head is provided at the outer end of the corresponding shaft pin of the square post.

[0010] Preferably, two annular ridges are provided on the outer side walls at both ends of the shaft, and the belt is located between the annular ridges.

[0013] Preferably, the top of both the first housing and the second housing is provided with a flexible rubber sleeve that is fitted over the belt body.

[0014] The beneficial effects of this invention are mainly reflected in its convenient and quick installation and disassembly, making it extremely easy to use. Specifically, during use, after the strap is wrapped around the limb requiring pressure, the first and second shells are joined together. Under magnetic adsorption, the first and second shells can be quickly positioned and assembled, forming a stable fixed relationship through the abutment ridge and abutment groove. Then, the user pulls the strap through the first shell to tighten it and adjust the pressure according to the required pressure. When worn, the reaction force applied to the first and second shells is mainly transmitted to the abutment ridge and abutment groove, and is a longitudinal force, ensuring reliable pressure. During disassembly, the first or second shell can be pushed laterally to quickly separate them, allowing for rapid removal of the invention. Attached Figure Description

[0019] This utility model relates to a device for removing a postoperative hemostatic device, used to achieve compression hemostasis at the postoperative puncture site or for emergency compression hemostasis of the limb, such as... Figure 1 As shown, this utility model includes a strap body 1 and quick-release heads 2 connected to both ends of the strap body 1. As the name suggests, the quick-release heads 2 are used to enable the strap body 1 to be put on quickly, adjust the pressure, and be removed quickly.

[0020] like Figure 1 As shown, the quick-release head 2 of this invention is composed of a first housing 3 and a second housing 4 joined together, and the two are magnetically attracted to each other. There are various specific ways to achieve this magnetic attraction. For example, a magnetic layer 7 can be provided on the lower part of the opposite side of the first housing 3 and the second housing 4, and magnetic attraction can be achieved through the magnetic layer 7. Alternatively, magnetic attraction blocks can be provided on the inner sidewalls of the opposite sides of the first housing 3 and the second housing 4, or magnetic attraction can be achieved by providing multiple pairs of small point magnets. The main function of the magnetic layer 7 is for the quick positioning and assembly of the first housing 3 and the second housing 4; it does not serve as a primary stress point after assembly.

[0021] To ensure stability under stress, this invention sets the opposing surfaces of the first shell 3 and the second shell 4 as stepped surfaces, and provides mutually cooperating arc-shaped abutment ridges 5 and abutment grooves 6 at the steps. Figure 1 As shown, the strap 1 is located at the top, and when it is tightened, the reaction force is supported by the resistance of the abutment 5 and the abutment groove 6, which greatly ensures the reliability when worn.

[0022] During use, the present invention involves wrapping the strap 1 around the limb requiring pressure, then joining the first shell 3 and the second shell 4. Under magnetic attraction, the first shell 3 and the second shell 4 can be quickly positioned and assembled, forming a stable fixed relationship through the abutment ridge 5 and the abutment groove 6. Next, the user pulls the strap 1, which passes through the first shell 3, to tighten the strap 1 and adjust the pressure according to the required pressure. When worn, the reaction force applied to the first shell 3 and the second shell 4 is mainly transmitted to the abutment ridge 5 and the abutment groove 6, and is a longitudinal force, ensuring reliable pressure. During disassembly, the present invention allows the first shell 3 or the second shell 4 to be pushed laterally; the two are only magnetically attracted laterally, allowing the first shell 3 and the second shell 4 to be quickly separated, thus enabling rapid removal of the present invention.

[0023] Of course, considering the need for rapid adjustment of the belt 1 to meet different pressure requirements, the first housing 3 of this invention is provided with a length adjustment mechanism. One end of the belt 1 enters through the inlet at the top of the first housing 3, passes around the length adjustment mechanism, and exits through the outlet at the bottom of the first housing 3. The other end of the belt 1 is connected to the top of the second housing 4.

[0024] The length adjustment mechanism can take many different structural forms. For example, it can be a D-ring buckle located inside the first housing 1, but in this case, an adjustment window usually needs to be opened on the side wall of the first housing 3. Alternatively, it can be, as... Figure 2 As shown, the length adjustment mechanism consists of a first rotating shaft 8 and a second rotating shaft 9 arranged side-by-side inside the first housing 3. The belt 1 is S-shaped and passes around the first rotating shaft 8 and the second rotating shaft 9. An adjustment component is provided at the second rotating shaft 9 to control the switching between a unidirectional rotation state and a free rotation state. That is, the first rotating shaft 8 is in a free rotation state, while the second rotating shaft 9 can switch between the two states.

[0025] like Figure 2 As shown, in the unidirectional rotation state, the second shaft 9 can rotate counterclockwise, allowing the belt 1 to be quickly pulled out from the lower end of the first housing 3, thereby increasing the compressive force of the belt 1. Since the second shaft 9 cannot rotate clockwise at this time, due to friction and the squeezing force between the two shafts, the belt 1 cannot be pulled upwards, ensuring stable compression. In free rotation, the second shaft 9 can rotate clockwise or counterclockwise, facilitating the upward withdrawal of the belt 1.

[0026] To achieve the above functions, such as Figure 3 As shown, the second rotating shaft 9 of this utility model includes a shaft body 10 and a square post 11. A square hole 12 extending along the length of the shaft body 10 is provided at the center of the shaft body 10. One end of the square post 11 passes through the square hole 12 and forms a sliding fit with the square hole 12. A return spring 13 is provided between the inner end of the square post 11 and the bottom of the square hole 12. A shaft pin 14 is provided at the opposite end of the shaft body 10 and the square post 11, and the shaft pin 14 passes through the first housing 3 and forms a rotational fit with the first housing 3.

[0027] To ensure positional stability between the shaft 10 and the belt 1, two annular ridges 18 are provided on the outer sidewalls at both ends of the shaft 10, and the belt 1 is located between the annular ridges 18. To improve the friction between the belt 1 and the shaft 10, an anti-slip layer is provided on the sidewall of the shaft 10 between the two annular ridges 18.

[0028] The adjustment assembly includes a ratchet 15 fixedly mounted on the square post 11 and a pawl 16 fixedly mounted inside the first housing 3 and cooperating with the ratchet 15. The cooperation relationship between the two is as follows: Figure 4 As shown in the figure. A pressing head 17 is provided at the outer end of the shaft pin 14 corresponding to the square column 11.

[0029] Under normal conditions, affected by the return spring 13, the ratchet 15 and the pawl 16 are opposite each other, and the second rotating shaft 9 cannot rotate clockwise (one-way rotation state). When the pressing head 17 is pressed, the square post 11 retracts, and the ratchet 15 disengages from the pawl 16, and the second rotating shaft 9 can rotate freely.

[0030] In addition, to further improve the stability of the connection between the first housing 3 and the second housing 4, a U-shaped buckle 19 is provided at the bottom of the first housing 3. The two ends of the buckle 19 are hinged to the first housing 3 and can swing to tighten the second housing 4. To ensure comfortable contact, a flexible rubber sleeve 20 can also be provided on the top of both the first housing 3 and the second housing 4, which is fitted over the belt body 1.
