Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a limb trauma hemostasis device. Background Art

[0002] At present, the tourniquets used in hospitals are mostly rubber tubes, which are tied to the proximal end of the patient's limb wound to compress and stop bleeding. However, the rubber tube often breaks after being tied, and needs to be tied again, which is easy to cause secondary damage to the patient's limbs, making it very inconvenient to use.

[0003] The existing patent CN215384316U is a trauma hemostasis device for emergency department. After wrapping gauze on the patient's wound, the proximal compression block can be moved downward by rotating the threaded rotating rod and under the pushing action of the threaded through hole, so that the proximal compression block gradually approaches the proximal part of the wound and compresses and tightens it, which effectively improves the hemostasis effect and can also effectively prevent the gauze from breaking apart. The auxiliary tight hoop can make the hemostasis device firmly cover the patient's limbs to prevent the hemostasis device from falling off the limbs, and can also ensure the compression and tightening effect of the proximal compression block, greatly improving the hemostasis effect.

[0004] However, in the process of using an existing patented trauma hemostasis device for emergency department, when the device is put on the patient's limb, the auxiliary tight hoop can only slide on the clamp and cannot be limited after sliding, which causes the auxiliary tight hoop to loosen easily, resulting in the overall fixation of the device being unreliable. Utility Model Content

[0005] The purpose of the utility model is to provide a limb trauma hemostasis device, which solves the problem that when the device is put on the patient's limb, the auxiliary tight hoop can only slide on the clamping hoop, and the auxiliary tight hoop cannot be limited after sliding, which causes the auxiliary tight hoop to be easily loosened, thereby causing the overall fixation of the device to be unreliable.

[0006] To achieve the above-mentioned purpose, the utility model provides a limb trauma hemostasis device, including a fixed semi-ring and a pressing device, the fixed semi-ring is provided with an arc groove, and a through groove is provided on one side of the fixed semi-ring close to the arc groove, and the through groove runs through the arc groove. The pressing device is installed on the fixed semi-ring and also includes a limiting device, and the limiting device includes a limiting arc rod, an elastic card, a fixed card block and a top pressing assembly. The limiting arc rod is slidably installed on the semi-ring and is located in the arc groove. The elastic card is fixedly installed on the semi-ring and is located in the arc groove. The fixed card block is fixedly installed on the limiting arc rod and is clamped with the elastic card. The top pressing assembly makes the limiting arc rod contact with the elastic card by top pressing.

[0007] Among them, the top pressure assembly includes a top pressure block, a first spring and a pull rod, the first spring is fixedly mounted on the semi-ring and is located in the arc groove; the top pressure block is fixedly mounted on the first spring and is in top pressure contact with the limiting arc rod; a circular hole is provided on the side of the fixed semi-ring close to the first spring, the circular hole is connected with the arc groove, the pull rod passes through the circular hole and is fixedly connected to the top pressure block.

[0008] Wherein, the limiting arc rod also includes a fixing rod, and the fixing rod is fixedly mounted on the limiting arc rod and passes through the through slot.

[0009] Wherein, the pressing device comprises a second spring and a pressing block, the second spring is fixedly mounted on the fixed half ring; the pressing block is fixedly mounted on the second spring.

[0010] Wherein, the pressing device also includes a pressure assembly, which includes a fixed screw and a pressure cylinder. The fixed screw is fixedly installed on the fixed half ring and is located on a side of the fixed half ring close to the pressing block; the pressure cylinder is threadedly connected to the fixed thread.

[0011] The utility model provides a limb trauma hemostasis device. When in use, the device is put on the proximal end of the patient's limb trauma, and then the fixing rods on both sides drive the limiting arc rods on both sides to slide along the arc groove toward the outside of the fixed semi-ring until the limiting arc rod wraps the patient's limb. While the limiting arc rod slides, due to the pressing effect of the pressing block, the limiting arc rod slides on the elastic card and causes the elastic card to bend. When the limiting arc rod is adjusted, due to the clamping effect between the elastic card and the fixed clamping block, the limiting arc rod cannot move. At this time, the device is firmly fixed on the patient's limb. At this time, the pressing device presses the patient's limb trauma to stop bleeding, thereby achieving the limiting effect of the limiting arc rod after movement, and avoiding the overall loosening of the device.

DETAILED DESCRIPTION

[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a limb trauma hemostasis device according to the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the limiting device of the first embodiment of the utility model.

[0020] The utility model provides a limb trauma hemostasis device: it includes a fixed half ring 101 and a pressing device, and also includes a limiting device, the limiting device includes a limiting arc rod 104, an elastic card 105, a fixed card block 106 and a top pressure component, the top pressure component includes a top pressure block 107, a first spring 108 and a pull rod 109, the limiting arc rod 104 also includes a fixed rod 111, and the above-mentioned scheme solves the above-mentioned problem that when the device is put on the patient's limb, the auxiliary tight hoop can only slide on the clamp and the auxiliary tight hoop cannot be limited after sliding, which causes the auxiliary tight hoop to be easily loosened, thereby causing the overall fixation of the device to be unreliable. It can be understood that this scheme can also be used to solve the problem of hemostasis of patient limb trauma.

[0021] In this embodiment, the clamping effect of the elastic card 105 and the fixed clamping block 106 is used to achieve the limiting effect of the limiting arc rod 104 after movement, thereby preventing the entire device from loosening.

[0022] The limiting arc rod 104 is slidably mounted on the semi-ring and is located in the arc groove 102. The elastic card 105 is fixedly mounted on the semi-ring and is located in the arc groove 102. The fixed card block 106 is fixedly mounted on the limiting arc rod 104 and is engaged with the elastic card 105. The top pressing component makes the limiting arc rod 104 and the elastic card 105 contact with each other. The number of the limiting devices is two groups, which are symmetrically distributed on both sides of the fixed semi-ring 101. The limiting arc rod 104 is an arc-shaped structure. The elastic card 105 is an elastic metal. There are multiple groups of elastic cards 105, which are distributed in a ring at the bottom end of the arc groove 102. The fixed card block 106 is a block structure and is welded on the limiting arc rod 104. The limiting arc rod 104 is pressed by the pressing assembly so that when the limiting arc rod 104 moves outward along the arc groove 102, the fixed card block 106 can move on the elastic card 105. When the movement is completed, due to the clamping effect of the fixed card block 106 and the elastic card 105, the limiting effect of the limiting arc rod 104 after movement is achieved, thereby avoiding the loosening of the entire equipment.

[0023] Secondly, the first spring 108 is fixedly mounted on the semi-ring and is located in the arc groove 102; the pressing block 107 is fixedly mounted on the first spring 108 and is in pressing contact with the limiting arc rod 104; a circular hole 110 is provided on the side of the fixed semi-ring 101 close to the first spring 108, and the circular hole 110 is connected with the arc groove 102, and the pull rod 109 passes through the circular hole 110 and is fixedly connected with the pressing block 107. The pressing block 107 is driven by the elastic force of the first spring 108 to push the limiting arc rod 104, thereby achieving a pressing effect on the limiting arc rod 104. When the limiting arc rod 104 needs to be reset, the pull rod 109 is pulled outward along the circular hole 110, so that the pull rod 109 drives the pressing block 107 to disengage from the limiting arc rod 104, and the limiting arc rod 104 can be moved and reset.

[0024] Again, the fixing rod 111 is fixedly mounted on the limiting arc rod 104 and passes through the through slot 103. Each group of the limiting arc rods 104 is provided with a group of fixing rods 111 fixed thereon. Through the setting of the fixing rods 111, the limiting arc rods 104 can be better driven to move.

[0025] In this embodiment, when in use, the device is put on the proximal end of the patient's limb injury as a whole, and then the limiting arc rods 104 on both sides are driven by the fixed rods 111 on both sides to slide along the arc groove 102 toward the outside of the fixed semi-ring 101 until the limiting arc rods 104 wrap the patient's limb. While the limiting arc rods 104 slide, due to the pressing action of the pressing block 107, the limiting arc rods 104 slide on the elastic card 105 and cause the elastic card 105 to bend. When the limiting arc rods 104 are adjusted, due to the clamping effect between the elastic card 105 and the fixed clamping block 106, the limiting arc rods 104 cannot move. At this time, the device as a whole is firmly fixed on the patient's limbs, and the pressing device presses the patient's limb injury to stop bleeding, thereby achieving the limiting effect of the limiting arc rods 104 after movement, and avoiding the loosening of the device as a whole.

[0026] The second embodiment of the present application is:

[0027] See also Figure 3 ,in Figure 3 It is a schematic diagram of the overall structure of a limb trauma hemostasis device according to the second embodiment of the utility model. On the basis of the first embodiment, the limb trauma hemostasis device according to this embodiment also includes a pressing device, which includes a second spring 201 and a pressing block 202. The pressing device also includes a pressure assembly, which includes a fixed screw 203 and a pressure cylinder 204.

[0028] In this embodiment, the second spring 201 pushes the pressing block 202 so that the pressing block 202 presses the wound on the patient's limb to stop bleeding.

[0029] Among them, the second spring 201 is fixedly installed on the fixed semi-ring 101; the pressing block 202 is fixedly installed on the second spring 201, the number of the second spring 201 is two groups, and they are symmetrically distributed on both sides of the inner side of the fixed semi-ring 101, and the pressing block 202 is an arc-shaped structure. When the device is integrally mounted on the proximal end of the patient's limb injury, due to the elastic force of the second spring 201, the pressing block 202 is pressed and contacted with the patient's limb, so that the pressing block 202 presses the patient's limb injury to stop bleeding.

[0030] Secondly, the fixing screw 203 is fixedly mounted on the fixing half ring 101 and is located on one side of the fixing half ring 101 close to the pressing block 202; the pressure cylinder 204 is threadedly connected to the fixing thread, and the fixing screw 203 is welded to the inner middle part of the fixing half ring 101. A thread is provided inside the pressure cylinder 204. By rotating the pressure cylinder 204, the pressure is moved downward along the fixing screw 203 through the threaded connection, and the pressing block 202 is pushed to make closer contact with the patient's limb, thereby making the pressing effect of the pressing block 202 better.

[0031] In this embodiment, when the device is entirely sleeved on the proximal end of the patient's limb wound, the elastic force of the second spring 201 causes the pressing block 202 to press against the patient's limb wound, thereby causing the pressing block 202 to press on the patient's limb wound to stop bleeding.

[0032] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
