A highly effective tourniquet

Abstract

This utility model provides a high-efficiency tourniquet, relating to the field of tourniquet technology. It includes a tourniquet body, a connecting collar, a first connecting member, a second connecting member, a vertical rod, a first auxiliary member, a second auxiliary member, and a third auxiliary member. By rotating the vertical rod, the first connecting member is coiled around its outer surface. As the first connecting member moves, the first auxiliary member moves closer to the vertical rod. This causes the third auxiliary member to shift, separating the toothed part from the blocking ring. At this point, the tourniquet body, located between the toothed part and the blocking ring, can be pulled, causing it to adhere tightly to the patient's wound. Then, the vertical rod can be released, eliminating the external tension on the third auxiliary member. This causes the toothed part to move back towards the blocking ring, thus preventing further movement of the tourniquet body and effectively stopping bleeding from the wound.

Description

Technical Field

[0001] This utility model relates to the field of tourniquet technology, and in particular to a high-efficiency tourniquet. Background Technology

[0002] An emergency tourniquet is a medical device used for first aid. It is typically made of medical-grade polymer materials such as natural rubber or special rubber, and is long, flat, and highly elastic. Inflatable tourniquets are characterized by a wide compression area, uniform pressure, and the ability to measure, display, and adjust pressure at any time using a connected pressure gauge. They are easy to operate and have a high level of safety. There are two types: electrically inflatable and manually inflatable. Electrically inflatable tourniquets are mainly used in operating rooms, but are inconvenient to carry. Manually inflatable tourniquets can be inflated manually, have a pressure display device, are easy to carry, and can monitor pressure. They can be used for pre-hospital emergency care, patient transport, and examinations.

[0003] While snap-on tourniquets are convenient to connect into a loop, the tightening method is inconvenient, leading to over-tightening (which can cause skin and limb necrosis) or poor tightening (resulting in ineffective hemostasis). Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a highly efficient tourniquet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency tourniquet, comprising a tourniquet body, a connecting collar being sleeved through one end of the tourniquet body, a first connecting member being sleeved through the inside of the connecting collar, a second connecting member being provided on one side of the first connecting member, a vertical rod being sleeved through the center of the first connecting member, a first auxiliary member being sleeved through one end of the first connecting member, and a second auxiliary member and a third auxiliary member being provided on one side of the first auxiliary member.

[0006] Preferably, a first limiting member and a second limiting member are fixedly connected to one side of the second connector, and a through groove is provided on one side of the vertical rod. The first connector passes through the space between the first limiting member and the second connector, passes through the interior of the through groove, and also passes through the space between the second limiting member and the second connector.

[0007] Preferably, the upper end of the first auxiliary component has an auxiliary groove, a screw is provided through one side of the first auxiliary component, a hook is fixedly connected to one side of the first auxiliary component, the interior of the auxiliary groove is sleeved with one end of the first connecting component, and the screw passes through the interior of the first auxiliary component and is threadedly connected to the second connecting component.

[0008] Preferably, the lower end of the second auxiliary component is fixedly connected to a first extension component, a round rod is fixedly connected to the inner wall of the first extension component, and a blocking ring is provided on the inner side of one end of the second auxiliary component.

[0009] Preferably, a second extension is fixedly connected to one side of the third auxiliary component, one end of the third auxiliary component is sleeved with a hook, and a toothed component is fixedly provided at the other end of the third auxiliary component. The toothed component corresponds to the blocking ring component. The second extension is located inside the first extension and passes through the outer surface of the round rod.

[0010] Preferably, one end of the tourniquet body is sleeved through the toothed part and the blocking ring part.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, rotating the vertical rod causes the first connecting member to coil around the outer surface of the vertical rod. As the first connecting member changes, it causes the first auxiliary member to move closer to the position of the vertical rod. At this time, the first auxiliary member causes the third auxiliary member to shift, and the third auxiliary member causes the second extension member to rotate along the circular rod, thereby causing the toothed member and the blocking ring to separate. At this time, the tourniquet body located between the toothed member and the blocking ring can be pulled, causing the tourniquet body to fit tightly against the patient's wound. Then, the vertical rod can be released, and the external pulling force on the third auxiliary member disappears, causing the toothed member to move closer to the blocking ring again. Thus, under the mutual cooperation of the toothed member and the blocking ring, the tourniquet body is prevented from moving again, thereby effectively stopping the bleeding of the wound.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1-5 As shown, a high-efficiency tourniquet includes a tourniquet body 1. A connecting collar 2 is sleeved through one end of the tourniquet body 1. A first connecting member 3 is sleeved through the inside of the connecting collar 2. A second connecting member 4 is provided on one side of the first connecting member 3. A vertical rod 5 is sleeved through the center of the first connecting member 3. A first auxiliary member 6 is sleeved through one end of the first connecting member 3. A second auxiliary member 7 and a third auxiliary member 8 are provided on one side of the first auxiliary member 6.

[0022] Furthermore, a first limiting member 41 and a second limiting member 42 are fixedly connected to one side of the second connecting member 4. A through groove 51 is provided through one side of the vertical rod 5. The first connecting member 3 passes through the space between the first limiting member 41 and the second connecting member 4. The first connecting member 3 passes through the interior of the through groove 51. The first connecting member 3 also passes through the space between the second limiting member 42 and the second connecting member 4. The presence of the first limiting member 41 and the second limiting member 42 is used to limit the first connecting member 3 and prevent the first connecting member 3 from detaching from the side of the second connecting member 4.

[0023] Furthermore, an auxiliary groove 61 is provided through the upper end of the first auxiliary component 6, a screw 62 is provided through one side of the first auxiliary component 6, and a hook 63 is fixedly connected to one side of the first auxiliary component 6. The interior of the auxiliary groove 61 is sleeved through one end of the first connecting component 3. The screw 62 passes through the interior of the first auxiliary component 6 and is threadedly connected to the second connecting component 4. The presence of the screw 62 is used to fix the first auxiliary component 6 to the side of the second connecting component 4. The auxiliary groove 61 is used to fix the first connecting component 3 to the side of the first auxiliary component 6. The presence of the hook 63 facilitates the connection between the third auxiliary component 8 and the first auxiliary component 6.

[0024] Furthermore, the lower end of the second auxiliary component 7 is fixedly connected to the first extension component 71, and the inner wall of the first extension component 71 is fixedly connected to the round rod 72. A blocking ring 73 is provided on the inner side of one end of the second auxiliary component 7. The presence of the round rod 72 facilitates the rotation of the second extension component 81 along it.

[0025] Furthermore, a second extension 81 is fixedly connected to one side of the third auxiliary component 8. One end of the third auxiliary component 8 is sleeved with the hook 63, and a toothed component 82 is fixedly provided at the other end of the third auxiliary component 8. The toothed component 82 corresponds to the blocking ring component 73. The second extension 81 is located inside the first extension 71 and passes through the outer surface of the round rod 72. One end of the tourniquet body 1 passes through and is sleeved between the toothed component 82 and the blocking ring component 73. The mutual cooperation between the toothed component 82 and the blocking ring component 73 is used to limit the tourniquet body 1.

[0026] Working principle: When it is necessary to stop bleeding from a patient's wound, firstly, place the second connector 4 on the opposite side of the wound and align the tourniquet body 1 with the front and top of the wound. Then, rotate the vertical rod 5 to coil the first connector 3 around the outer surface of the vertical rod 5. As the first connector 3 moves, it will cause the first auxiliary component 6 to move closer to the position of the vertical rod 5. At this time, the first auxiliary component 6 will cause the third auxiliary component 8 to shift, and the third auxiliary component 8 will cause the second extension 81 to rotate along the round rod 72, thereby causing the toothed groove to... When component 82 separates from the blocking ring component 73, the tourniquet body 1 located between the toothed component 82 and the blocking ring component 73 can be pulled. This causes the tourniquet body 1 to adhere tightly to the patient's wound. Then, the vertical rod 5 can be released. At this time, the external pulling force on the third auxiliary component 8 disappears, causing the toothed component 82 to move closer to the blocking ring component 73. Thus, under the cooperative action of the toothed component 82 and the blocking ring component 73, the tourniquet body 1 is prevented from moving again, thereby effectively stopping the bleeding of the wound.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
