Description

[Technical Field]

[0001] This invention relates to the technical field of tourniquets, and in particular to a tourniquet device that is easy to operate. [Previous Technology]

[0002] Note that conventional tourniquet devices mostly involve wrapping a tourniquet around a wound to achieve hemostasis. However, this method of tightening a tourniquet is only suitable for small wounds; it is ineffective for larger wounds. To address this, manufacturers have developed an adjustable tourniquet. This involves securing the tourniquet to the wound and then tightening it further using a buckle, adjusting the tightness as needed to achieve hemostasis. However, this method requires manual tightening, which expends considerable effort, resulting in low efficiency and difficulty in controlling the force applied, leading to the tourniquet being too loose or too tight. [Summary of the Invention]

[0003] The main objective of this invention is to provide a tourniquet device that allows for fine adjustment of the tightness of the webbing by rotating a rocker arm, thereby achieving hemostasis and being easy to operate.

[0014] Please refer to Figures 1 to 7. The present invention is a tourniquet device, comprising:

[0015] The hemostatic seat 1 is generally U-shaped and has a seat window portion 10 and a first side portion 11 and a second side portion 12 provided on both sides of the seat window portion 10. The seat window portion 10 has a plurality of windows 100. The first side portion 11 and the second side portion 12 have corresponding first pivot holes 110 and second pivot holes 120, respectively, and the first side portion 11 and the second side portion 12 are laterally connected to a recording portion 13.

[0016] The drive shaft 2 has a shaft 20 and a first joint 21 and a second joint 22 provided at both ends of the shaft 20. The shaft 20 is provided with a groove 200 and a first pivot hole 110 passing through the first side 11 and a second pivot hole 120 passing through the second side 12. The first joint 21 and the second joint 22 are respectively exposed on the outer surfaces of the first side 11 and the second side 12. The first joint 21 has a joint groove 210. The joint groove 210 and the second joint 22 have a first joint hole 211 and a second joint hole 220 respectively.

[0017] The webbing 3 has a fixed end 30 and a free end 31 at both ends. The fixed end 30 is fixed to the seat window 10. The free end 31 is wound out to form an adjustable annular space 32 and then passes through any window 100 of the seat window 10 into the hemostatic seat 1. It then winds into the groove 200 of the drive shaft 2 and is rotatably connected to the drive shaft 2.

[0018] The rocker arm 4 has a third connection hole 40 at one end that corresponds to the first connection hole 211 of the connection groove 210. The first connection hole 211 and the third connection hole 40 are passed through the first connection member 41 so that the rocker arm 4 is connected to the connection groove 210 of the first connection part 21.

[0019] The gear assembly 5 includes a gear 50, a pivot 51, an elastic member 52, a second set of connectors 53, and a pivot member 54. The gear 50 has a fourth set of connector holes 500 corresponding to the second set of connectors 22. After the second set of connectors 22 of the drive shaft 2 passes through the fourth set of connector holes 500, the second set of connectors 53 passes through the second set of connector holes 220 of the second set of connectors 22, so that the gear 50 and the second set of connectors 22 of the drive shaft 2 are rotatably connected. The end face of the gear 50 has a plurality of tooth grooves 501. One end of the pivot 51 is pivotally connected to the second side portion 12 through the pivot member 54, and the other end has teeth 510 that mesh with each tooth groove 501. One end of the elastic member 52 is connected to the pivot 51, and the other end is connected to the second side portion 12. The elastic member 52 causes the pivot 51 to pivot up and down.

[0020] This invention provides a tourniquet device for animals. After the annular space 32 of the webbing 3 is placed around the animal's wound, the rocker arm 4 is rotated to drive the transmission shaft 2 and the gear 50 to rotate synchronously. By rotating the transmission shaft 2, the annular space 32 of the webbing 3 is gradually tightened to stop the bleeding of the animal's wound. The time of hemostasis can be recorded in the recording part 13 of the tourniquet seat 1. It is worth mentioning that when the gear 50 rotates, its tooth grooves 501 and the teeth 510 of the pivot member 51 interlock to fix the tightness of the annular space 32 of the webbing 3. The pivot member 51 forms an up-and-down pivot by means of the elastic member 52. Therefore, no matter how the gear member 50 rotates, the teeth 510 of the pivot member 51 and the tooth grooves 501 of the gear member 50 can always maintain the interlocking relationship, avoiding the transmission shaft 2 from spinning freely. When removing or replacing the webbing 3, move the pivot 51 to disengage the gear engagement between the pivot 51 and the gear 50, then pull the webbing 3 out of the groove 200 and the seat window 10. If emergency treatment by medical personnel is required, the webbing 3 can be cut directly with a tool (e.g., scissors) to achieve the effect of quickly removing the webbing 3.

[0021] With the above-described structure, the present invention can finely adjust the tightness of the annular space 32 of the webbing 3 simply by turning the rocker arm 4. The operation is easy and there is no need to tie the webbing 3. The webbing 3 will not get tangled with the fur of the animal's limbs, which can greatly reduce the animal's discomfort.

[0022] Furthermore, conventional tourniquets are all used to tighten the hemostatic area once. If the tightness of the tourniquet needs to be adjusted, it is necessary to loosen the tourniquet and then re-wrap it by hand, which is quite inconvenient. However, in this case, if the tightness of the annular space 32 of the webbing 3 needs to be adjusted, it is only necessary to move the pivot 51 to disengage it from the gear 50, pull the webbing 3 out of the groove 200 and the seat window 10, and then turn the rocker arm 4 to tighten the annular space 32 of the webbing 3 again. It is not necessary to re-wrap it by hand like conventional tourniquets, which is much easier to operate.

[0023] In summary, the structure disclosed in the "tethering device" of this invention has an unprecedented innovative structure, so its "novelty" is beyond doubt. Furthermore, the invention can improve the efficiency of conventional structures, thus it also has "progressiveness". It fully complies with the provisions of the Patent Law of our country concerning invention patent applications. Therefore, we hereby file a patent application with your office in accordance with the law, and earnestly request your office to grant the patent right in this case as soon as possible.
