Description

Technical Field

[0001] This utility model relates to the field of medical hemostasis technology, and in particular to a tourniquet that is not easily loosened. Background Technology

[0002] During hemodialysis, an arteriovenous fistula (AVF) puncture is required to establish a circulatory pathway for hemodialysis. The AVF puncture needle is relatively large, resulting in a significant wound after puncture. After removal, prolonged pressure with gauze is necessary to stop the bleeding. Due to the extended pressure, an elastic bandage is typically used to secure the gauze around the arm. However, prolonged use of a tourniquet with a regular elastic bandage can lead to AVF thrombosis, potentially obstructing blood flow, slowing hematoma resolution, and even causing complications such as hemangiomas. Conversely, insufficient pressure or too short a duration of bandaging can lead to massive bleeding. Therefore, strict control of pressure time and force is crucial.

[0003] As per existing technology, patent document CN214632602U discloses a hemostatic bandage, including a bandage body with a main body segment. A display panel is located on one side of the main body segment. The main body segment includes a timer, a bleeding sensor, a pressure monitor, and an alarm. The bandage body and the main body segment are detachably connected. Lugs are located on both sides of the main body segment. The bandage body includes a first band and a second band, with snaps on one side of each band for engaging with the lugs. This hemostatic bandage can effectively quantify the bandaging pressure and time of an arteriovenous fistula, prolonging its use and effectively preventing complications. However, because the detachable connection between the lugs and the band is achieved through snaps, the snaps are easily subjected to external forces during use, causing the locking pin to easily detach from the mounting hole, thus affecting the accuracy and stability of the bandaging pressure. Utility Model Content

[0004] The purpose of this invention is to provide a tourniquet that is not easily loosened, thereby improving the stability of the connection between the compression element and the bandage assembly and avoiding affecting the accuracy and stability of the bandaging pressure.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include: Tourniquets that are not easily loosened include: A compression member for applying pressure to a hemostatic point and a bandage assembly for wearing, wherein a connecting assembly for connecting the compression member and the bandage assembly is provided; The connecting assembly includes a connecting ring respectively disposed on both sides of the compression member, and each of the two connecting rings has a sleeve ring movably disposed in its inner cavity. The two sleeve rings are respectively disposed at both ends of the strap assembly. The connecting ring includes an upper baffle fixedly connected to the pressing member, a lower baffle fixedly connected to the surface of the pressing member opposite to the upper baffle, and a side baffle movably connected to the upper baffle that can engage with one side of the lower baffle.

[0006] As a preferred technical solution, the upper baffle, lower baffle and side baffle form a receiving cavity that can accommodate the collar.

[0007] As a preferred technical solution, a groove is provided on one side of the upper baffle, and a protrusion is integrally formed on the side of the side baffle away from the lower baffle, and one side of the protrusion is rotatably connected to the inner wall of the groove.

[0008] As a preferred technical solution, the inner cavity of the groove is provided with a torsion spring, and the two pins of the torsion spring are respectively fixedly connected to the upper baffle and the side baffle.

[0009] As a preferred technical solution, a limiting rod is inserted inside the torsion spring, and the two ends of the limiting rod are respectively fixedly connected to two protrusions.

[0010] As a preferred technical solution, the strap assembly includes a first strap and a second strap respectively disposed on both sides of the compression member, one end of the first strap is fixedly connected to one of the collars, and one end of the second strap is fixedly connected to the other collar.

[0011] As a preferred technical solution, the other end of the second strap is integrally formed with a limiting ring that matches the first strap, a pin is fixedly connected to the second strap, and a pin hole that matches the pin is opened on the first strap.

[0012] As a preferred technical solution, the pin holes are distributed equidistantly on the first strap.

[0013] This utility model has at least the following beneficial effects: The beneficial effect of this utility model is that by moving the collar towards the compression member to the maximum extent, and then pressing the side baffle into the receiving cavity to the maximum extent, the collar can be removed, thus completing the disassembly of the bandage assembly. The connection component enables a detachable connection between the compression member and the bandage assembly, which not only facilitates the individual replacement of the bandage assembly, but also improves the stability of the connection between the compression member and the bandage assembly. This effectively prevents the bandage assembly from loosening due to external force collisions when wearing the tourniquet, thereby helping to ensure the effectiveness of the tourniquet in the future.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 The present invention provides a tourniquet that is not easily loosened, comprising: a compression member 1 for compressing the hemostatic point, a strap assembly 2 for wearing, and a connecting assembly 3 for connecting the compression member 1 and the strap assembly 2. The connecting assembly 3 is provided on both sides of the compression member 1. The connecting assembly 3 includes a connecting ring 31 respectively provided on both sides of the compression member 1. The inner cavity of each of the two connecting rings 31 is provided with a sleeve ring 32. The two sleeve rings 32 are respectively provided at both ends of the strap assembly 2. The connecting ring 31 includes an upper baffle 311 fixedly connected to the compression member 1. A lower baffle 312 opposite to the upper baffle 311 is fixedly connected to the surface of the compression member 1. A side baffle 313 that can engage with one side of the lower baffle 312 is movably connected to the upper baffle 311.

[0018] It should be noted that the aforementioned compression element 1 can intuitively, quantitatively, and display the hemostasis time and pressure, enabling the applied pressure to achieve effective hemostasis. It can also record the pressure of each effective hemostasis and provide a pressure quality control range for reference, which can then be used for the next hemostasis. The structure and working principle of the compression element 1 are consistent with the prior art (such as the main body of the patent with publication number CN214632602U), so it will not be described in detail in this technical solution.

[0019] The upper baffle 311, lower baffle 312, and side baffle 313 form a receiving cavity that can accommodate the collar 32. The upper baffle 311, lower baffle 312, side baffle 313, and collar 32 work together to achieve a movable connection between the pressing member 1 and the strap assembly 2.

[0020] The upper baffle 311 has a groove 314 on one side, and the side baffle 313 away from the lower baffle 312 has a protrusion 315 integrally formed on one side. One side of the protrusion 315 is rotatably connected to the inner wall of the groove 314 via a pivot. By using the groove 314 and the protrusion 315 together, the side baffle 313 can rotate around the pivot towards the inner cavity of the receiving cavity, so that the collar 32 can be removed from the connecting ring 31 later.

[0021] The groove 314 has a torsion spring 316 inside, and the two pins of the torsion spring 316 are fixedly connected to the upper baffle 311 and the side baffle 313 respectively. Under the elastic action of the torsion spring 316, the side baffle 313 can always be engaged with the lower baffle 312, and can automatically reset the side baffle 313.

[0022] The torsion spring 316 has a limiting rod 317 inserted inside it, and the two ends of the limiting rod 317 are fixedly connected to two protrusions 315 respectively. The limiting rod 317 can limit the torsion spring 316 and effectively prevent the torsion spring 316 from bending and deforming.

[0023] The strap assembly 2 includes a first strap 21 and a second strap 22 respectively located on both sides of the compression member 1. One end of the first strap 21 is fixedly connected to one of the loops 32, and one end of the second strap 22 is fixedly connected to the other loop 32. The first strap 21, the second strap 22, and the limiting ring 23 are all made of safe, non-irritating, soft, and elastic silicone material, which is easy to clean and disinfect. By using the first strap 21 and the second strap 22 together, the compression member 1 can be worn on the arm to fix the cotton gauze.

[0024] The second tourniquet 22 has an integrally formed limiting ring 23 at its other end, which is adapted to the first tourniquet 21. A pin 24 is fixedly connected to the second tourniquet 22, and a pin hole 25 adapted to the pin 24 is provided on the first tourniquet 21. The use of the limiting ring 23, pin 24, and pin hole 25 facilitates the connection between the first tourniquet 21 and the second tourniquet 22, which helps to improve the wearing efficiency of the tourniquet that is not easy to loosen.

[0025] The tourniquet 25 has multiple pin holes 25 evenly distributed on the first bandage 21. The pins 24 are inserted into the cavities of the pin holes 25 at different positions, so that the tourniquet that is not easy to loosen can be used for patients with different arm circumferences.

[0026] The working principle of this utility model is as follows: When it is necessary to replace the strap assembly 2, press the side baffle 313 into the receiving cavity with force, so that the side baffle 313 drives the protrusion 315 and the limiting rod 317 to rotate synchronously around the pivot. The torsion spring 316 is compressed under force until the side baffle 313 rotates to the maximum extent, so that the collar 32 can be taken out from the gap between the upper baffle 311 and the lower baffle 312. Align the collar 32 on the replaced first strap 21 and second strap 22 with the corresponding side baffle 313 and press it into the receiving cavity with force, so that the collar 32 is placed in the receiving cavity, thereby completing the connection operation between the pressure member 1 and the strap assembly 2.

[0027] The following data apply to tourniquet pressure (kPa), compression time (minutes), and compression frequency (release interval) for different patients: 1. For general patients: apply pressure of 40-45 kPa for 60-120 minutes, and release pressure every 30 minutes. 2. For patients with poor coagulation function: the pressure should be 35-40 kPa, the compression time should be 90-150 minutes, and the pressure should be released every 30 minutes; 3. Elderly patients: Pressure should be 38-43 kPa, compression time should be 60-90 minutes, and release every 20 minutes; For pediatric patients: apply pressure of 25-30 kPa for 30-60 minutes, and release pressure every 15 minutes.

[0028] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
