Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a general surgery pressure tourniquet. Background Art

[0002] Pressurized tourniquets are a common medical device used in general surgery and other medical settings involving hemostasis. Currently, these commonly used pressurized tourniquets typically use an air pump or manual pump to inject gas into the balloon to inflate it, generating pressure at the site of bleeding. For example, patent CN215079195U uses an air pump, while patent CN218899582U uses a manual pressure pump.

[0003] However, these two existing methods have limitations in certain situations. Air pumps rely on an external power source and may not function properly in emergency situations, such as those outdoors where there's no power, thus hindering tourniquet use. While manual pressure pumps don't rely on a power source, they are typically bulky, occupying a considerable amount of space and making them difficult to carry. They also require considerable strength and space to operate, making them ineffective for quickly and effectively stopping bleeding in emergencies.

[0004] Therefore, in view of the shortcomings of existing pressurized tourniquets in outdoor emergency hemostasis scenarios, a new tourniquet pressurization method is needed that is not dependent on external power supply and is more convenient, easy to operate and easy to carry, so as to meet the emergency hemostasis needs in various complex environments. Utility Model Content

[0005] The utility model aims to provide a general surgery pressurized tourniquet, which realizes tourniquet pressurization by squeezing and expanding an air bag.

[0006] The utility model is realized through the following technical solutions:

[0007] A general surgery compression tourniquet, comprising:

[0008] a band body having a strap for securing the entire band body to the affected area;

[0009] an assembly plate, which is arranged on the binding strap, and is provided with a first through hole;

[0010] A pressurized plywood having an outer surface and an inner surface disposed opposite to each other in a thickness direction, a second through hole extending through the outer surface and the inner surface, the outer surface of the pressurized plywood being connected to the assembly plate, and an accommodating cavity being disposed within the pressurized plywood;

[0011] an expansion airbag disposed in the accommodating cavity;

[0012] An extrusion rod is disposed in the first through hole of the assembly plate and is configured to be movable in the first through hole. When the extrusion rod is squeezed toward the inflatable airbag, at least a portion of the inflatable airbag is exposed from the second through hole.

[0013] In one embodiment of the present invention, an inner wall of the first through hole is provided with an internal thread, and an outer wall of the extrusion rod is provided with an external thread connected to the internal thread.

[0014] In one embodiment of the present invention, the assembly plate is symmetrically provided with mounting holes on both sides of the first through hole.

[0015] In one embodiment of the present invention, the inner surface of the pressurized laminating plate is an arc-shaped surface that fits the curve of the human body.

[0016] In one embodiment of the present invention, gauze is further included, and gauze is provided on the inner surface of the pressurized laminating plate in an area other than the second through hole.

[0017] In one embodiment of the present invention, the gauze is arranged on the inner surface of the pressurized laminating plate by double-sided tape.

[0018] In one embodiment of the present invention, the second through hole is rectangular.

[0019] In one embodiment of the present invention, the diameter of the extrusion rod is greater than three quarters of the length of the second through hole.

[0020] The beneficial effects of the utility model are:

[0033] like Figures 1 to 4 The general surgery pressure tourniquet shown includes a band body, an assembly plate 2, a pressure laminating plate 3, an inflation airbag 4 and an extrusion rod 5. The band body has a band 1 for fixing the entire band body to the affected area; the assembly plate 2 is arranged on the band 1, and the assembly plate 2 is provided with a first through hole 21; the pressure laminating plate 3 has an outer surface 31 and an inner surface 32 arranged opposite to each other along the thickness direction, and a second through hole 33 is provided on the pressure laminating plate 3 that passes through the outer surface 31 and the inner surface 32. The outer surface 31 of the pressure laminating plate 3 is connected to the assembly plate 2, and the interior of the pressure laminating plate 3 is provided with an accommodating cavity; the inflation airbag 4 is arranged in the accommodating cavity; the extrusion rod 5 is arranged in the first through hole 21 of the assembly plate 2, and the extrusion rod 5 is configured to be able to move in the first through hole 21. When the extrusion rod 5 is squeezed toward the inflation airbag 4, at least a portion of the inflation airbag 4 is exposed from the second through hole 33.

[0034] In this embodiment, the general surgery pressurized tourniquet comprises multiple components, including a band body, an assembly plate 2, a pressurized laminating plate 3, an inflatable airbag 4, and an extrusion rod 5. These components work together to achieve hemostasis. Specifically, the band body's strap 1 secures the entire tourniquet to the affected area, ensuring it does not shift during use. The extrusion rod 5 moves within the first through-hole 21 of the assembly plate 2, squeezing the inflatable airbag 4, extruding it from the second through-hole 33 of the pressurized laminating plate 3, thereby achieving precise pressure control and hemostasis. The inflatable airbag 4 is housed within the accommodating cavity of the pressurized laminating plate 3. This layout protects the airbag and makes the overall structure more compact.

[0035] First, the present invention does not rely on an external power source, which is very critical in emergency situations such as those encountered outdoors where there is no power supply. By squeezing the inflatable airbag 4, at least a portion of the inflatable airbag 4 is exposed from the second through hole 33 to achieve pressurization of the tourniquet, thus avoiding the problem of being unable to use the air pump due to lack of power. Secondly, compared with a manual pressure pump, the method of squeezing the inflatable airbag 4 of the present invention is more convenient and easy to operate, and can even be operated with one hand in actual operation, which is very important for the injured who need to stop bleeding quickly in an emergency. In addition, the innovative design of the squeezing inflatable airbag 4 of the present invention can be integrated into the tourniquet, making the entire structure more compact and lightweight, not taking up extra space, and convenient to carry during outdoor activities, thereby improving the portability and practicality of the tourniquet.

[0036] In this embodiment, the inner wall of the first through hole 21 is provided with an internal thread, and the outer wall of the extrusion rod 5 is provided with an external thread connected to the internal thread, that is, the extrusion rod 5 is installed in the first through hole 21 via a threaded connection. First, the threaded connection allows the extrusion rod 5 to move precisely within the first through hole 21. The user can precisely control the degree of compression of the extrusion rod 5 on the inflatable airbag 4 by rotating the extrusion rod 5 according to actual needs, thereby achieving precise adjustment of the pressure applied to the tourniquet, ensuring the hemostatic effect while avoiding excessive or insufficient pressure that may adversely affect the injured person. Second, the threaded connection provides strong connection stability. During use, the extrusion rod 5 is not prone to loosening or displacement, thereby ensuring the reliability and stability of the tourniquet during use and ensuring that it can continuously and effectively apply pressure to the affected area to stop bleeding. In addition, the threaded design makes operating the extrusion rod 5 relatively simple and convenient. The user only needs to rotate the extrusion rod 5 to squeeze the inflatable airbag 4, without the need for other complicated operating steps. Even in an emergency, the operation can be performed quickly and accurately. Therefore, this design provides a more precise, stable and convenient operation method for the use of general surgery pressure tourniquet, which helps to improve the use effect and safety of the tourniquet.

[0037] In this embodiment, the assembly plate 2 is symmetrically provided with mounting holes 22 on either side of the first through hole 21. Correspondingly, two mounting holes 22 (not shown) can be similarly symmetrically provided at corresponding positions on the bandage 1. In this manner, the assembly plate 2 can be mounted on the corresponding positions of the bandage 1 using bolts and nuts. This bolt-and-nut connection provides a strong fastening force, ensuring that the assembly plate 2 will not easily loosen or fall off during use, thereby ensuring the stability and reliability of the entire tourniquet structure. This connection method is relatively simple to operate, and when the assembly plate 2 needs to be installed or replaced, it can be easily disassembled and assembled, improving ease of use.

[0038] In this embodiment, the inner surface 32 of the pressure-applying plate 3 is a curved surface that conforms to the curves of the human body. First, this curved surface design can better adapt to the curves of different parts of the human body. When the tourniquet is fixed to the affected area, the inner surface 32 of the pressure-applying plate 3 can closely adhere to the human skin, ensuring that the pressure applied by the inflatable airbag 4 is evenly distributed across the hemostatic area, improving the hemostatic effect. Compared with a flat design, a curved surface can reduce localized pressure concentration and reduce the risk of damage to the skin and tissue. Second, the tightly fitting curved surface increases the friction between the tourniquet and the body, preventing the tourniquet from shifting or sliding during use, ensuring that the tourniquet remains stably fixed to the affected area and continuously and effectively exerts its hemostatic effect. Furthermore, a good fit can improve patient comfort. During the hemostatic process, patients may need to wear a tourniquet for an extended period of time. If the inner surface 32 of the pressure-applying plate 3 does not conform well to the body's curves, this can cause discomfort or even pain. The curved surface design can reduce this discomfort, making it easier for patients to accept and cooperate with treatment. Therefore, designing the inner surface 32 of the pressure-bonding plate 3 as an arc-shaped surface that fits the curve of the human body is a scientific and reasonable design, which can significantly improve the hemostatic effect, stability and patient comfort of the general surgery pressure tourniquet, and has important clinical application value.

[0039] In this embodiment, the general surgery pressure tourniquet also includes gauze 6, which is provided on the inner surface 32 of the pressure-bonded plate 3 in the area other than the second through hole 33. Preferably, the gauze 6 is provided on the inner surface 32 of the pressure-bonded plate 3 by double-sided tape 7. First, the gauze 6 is soft and breathable and can directly contact the wound or skin, avoiding friction and damage that may be caused by direct contact between the pressure-bonded plate 3 and the affected area; at the same time, the gauze 6 can absorb blood and tissue fluid exuded from the wound, keeping the area around the wound clean and dry, helping to prevent infection and promote wound healing. Secondly, the gauze 6 is fixed to the pressure-bonded plate 3 by double-sided tape 7, so that the gauze 6 can be easily replaced. When the gauze 6 is contaminated by blood or other contaminants, a new gauze 6 can be promptly replaced to keep the tourniquet clean and hygienic. In addition, this fixing method also facilitates the separate cleaning and disinfection of the gauze 6, which is conducive to the reuse of the tourniquet. In addition, the double-sided tape 7 can ensure that the gauze 6 is firmly attached to the inner surface 32 of the pressurized laminating plate 3 and will not shift or fall off during use. This ensures that the gauze 6 always maintains a good fit with the human skin, thereby better playing its protective and hemostatic role.

[0040] In this embodiment, the second through hole 33 is rectangular, and the diameter of the extrusion rod 5 is greater than three-quarters of the length of the second through hole 33. When the extrusion rod 5 compresses the inflatable airbag 4, the larger diameter of the extrusion rod 5 provides a larger contact area with the inflatable airbag 4, thereby ensuring more uniform pressure distribution on the airbag. This uniform pressure distribution helps achieve better hemostasis and reduces damage to surrounding tissue caused by excessive local pressure.

[0041] In this embodiment, the ends of the bandage 1 are provided with a Velcro surface (not shown) and a Velcro hook surface (not shown). First, the Velcro design makes the tourniquet fastening and adjustment very convenient and quick. During use, the bandage 1 only needs to be wrapped around the affected area and then the Velcro surface and hook surface are gently pressed together to complete the fixation. The operation is simple and can be completed quickly even in an emergency. At the same time, by adjusting the Velcro's contact position, the tightness of the tourniquet can be easily adjusted to suit the needs of different patients and different parts of the body. Second, the Velcro has a strong adhesive force, which ensures that the tourniquet will not easily loosen or fall off during use, thereby ensuring the stability and reliability of the hemostatic effect. Moreover, the Velcro's adhesive force can maintain its good performance after multiple uses, extending the lifespan of the tourniquet. In addition, the Velcro material is relatively soft and will not cause irritation or damage to the patient's skin, improving the patient's comfort. Compared with traditional fixing methods such as buttons or laces, Velcro fits better to the human skin and reduces the discomfort and pain caused by the fixing device. Therefore, providing Velcro fleece and Velcro hook surfaces at both ends of the bandage 1 of the general surgery pressure tourniquet is a very practical and effective design, which not only facilitates use and adjustment, improves the stability and reliability of the hemostatic effect, but also increases the comfort of the patient.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
