Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an upper limb stabilizer and a radial artery compression component. Background Art
[0002] Coronary atherosclerotic heart disease (hereinafter referred to as coronary heart disease) is an important disease that affects human health. Percutaneous coronary intervention (PCI) is one of the important treatments for coronary heart disease. The principle of percutaneous coronary intervention is to puncture a peripheral artery (radial artery in the hand or femoral artery in the thigh), insert an arterial sheath, insert an angiographic guidewire through the sheath, and then send the coronary artery guidance catheter to the coronary artery opening through the angiographic guidewire. After the catheter is in place, the guide wire for treatment is sent through the inner lumen of the catheter through the tortuous blood vessels to the distal end of the blood vessel to establish a track, and then the balloon for dilating the blood vessels and the stent for further treatment are sent through the guidewire. After the operation is completed and the above-mentioned catheter guidewire is withdrawn from the body, the puncture wound of the blood vessel needs to be compressed with an elastic bandage or a professional compressor to stop bleeding.
[0003] At present, most of the clinical coronary interventions are performed through the radial artery approach (TRA). Compared with the traditional percutaneous coronary intervention through femoral artery puncture, radial artery puncture has the advantages of less trauma, fewer bleeding complications and less pain for patients. However, since the radial artery and the brachial artery on the path are relatively small compared with the axillary artery, some patients are prone to hematoma of the radial artery or brachial artery after radial artery intervention, which leads to swelling of the forearm. Some patients may even develop compartment syndrome, and severe cases may even lead to ischemic necrosis of the forearm and serious complications. Although there are currently a variety of radial artery compressors invented for radial artery puncture, it is found in clinical applications that these radial artery compressors do not prevent and treat upper limb swelling caused by hematoma of the brachial artery path on the radial artery puncture path.
[0004] Therefore, how to solve the technical problem that the radial artery compressor in the prior art cannot prevent and treat upper limb swelling caused by transradial artery puncture has become an important technical problem that people in this field need to solve. Summary of the invention
[0005] The purpose of the present invention is to provide an upper limb stabilizer and a radial artery compression assembly, which solves the technical problem that the radial artery compression device in the prior art cannot prevent and treat upper limb swelling caused by puncture through the radial artery. The preferred technical solutions among the many technical solutions provided by the present invention can produce many technical effects as described below.
[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] Preferably, the first pressing member and the second pressing member both include a bracket, a knob penetrating the bracket and connecting belts arranged on both sides of the bracket, the knob is slidably locked with the bracket and the lower end of the knob extends through the lower part of the bracket to abut and press against the corresponding position of the upper limb.
[0009] Preferably, the knob comprises a screw rod and a pressing plate, the screw rod is threadedly connected to the bracket, and the pressing plate is connected to the lower part of the screw rod and performs vertical lifting and lowering movement with the screw rod.
[0010] Preferably, the cooling member comprises a bag body and a cooling material filled in the bag body, the bag body extends to the lower part of the first pressing member and the second pressing member, and a through hole for the knob to pass through is preset on the bag body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] The upper limb stabilizer provided by the present invention can perform targeted pressure application at the position of the brachial artery by arranging a first pressure piece, a second pressure piece and a cooling piece. When puncturing via the radial artery approach, the risk of upper limb bleeding can be greatly reduced by adding a compression point at the position of the brachial artery, and the stability of the system can be increased.

When the present invention is worn on the upper limb of the human body, the first pressing member 1 and the second pressing member 2 can both be pressed at the position of the brachial artery 4 of the upper limb. In this way, the present invention can perform targeted pressure pressing at the position of the brachial artery 4, and when puncturing through the radial artery 13, by adding a compression point at the position of the brachial artery 4, The risk of upper limb bleeding is greatly reduced and the stability of the system is increased. When the compression point of the radial artery 13 fails, the first compression member 1 and the second compression member 2 at the brachial artery 4 can effectively and temporarily strengthen the compression of the upper limb vein, which can greatly prevent the occurrence of upper limb hematoma. Moreover, by adding a cooling member 3 between the second compression member and the second compression member 2, the upper limb can be cooled and iced, which can significantly prevent and reduce the scope of upper limb hematoma and play a role in reducing swelling and treating swelling, thereby solving the technical problem that the radial artery compressor in the prior art cannot prevent and treat upper limb swelling caused by puncture through the radial artery approach.
[0032] Embodiment 2:
[0033] Reference Figure 2-5Based on Example 1, this embodiment further limits the structures of the first pressing member 1 and the second pressing member 2. In this embodiment, the upper limb stabilizer at least includes a first pressing part 1, a second pressing part 2 and a cooling part 3 arranged in parallel, and the cooling part 3 is arranged between the first pressing part 1 and the second pressing part 2.

With such an arrangement, the connecting belt 7 can connect and fix the bracket 5 to the upper limb of the human body, and the user can adjust the knob 6 to make the knob 6 perform vertical lifting and lowering movements relative to the bracket 5, and the lower end of the knob 6 can abut and press against the corresponding position of the upper limb with different forces, that is, the user can adjust the pressing force on the corresponding position of the upper limb by adjusting the knob 6, which is convenient to use and adjust.
[0034] Furthermore, the knob 6 includes a screw rod 8 and a pressing plate 9, the screw rod 8 is threadedly connected to the bracket 5, the pressing plate 9 is connected to the lower part of the screw rod 8 and moves vertically up and down with the screw rod 8. With such a configuration, the user rotates the adjustment screw rod 8 to drive the pressing plate 9 to move vertically up and down relative to the bracket 5. After the pressing plate 9 is in contact with the corresponding position of the upper limb, the screw rod 8 and the bracket 5 are locked by threads, and the knob 6 is in contact with the upper limb by setting the pressing plate 9 at the bottom, which can increase the contact and pressing area between the knob 6 and the corresponding position of the upper limb, and the force is evenly applied and has a better pressing effect. Among them, the lower part of the pressing plate 9 can be stacked with a buffer layer to avoid rigid contact between the pressing plate 9 and the upper limb, which is uncomfortable to wear. The material of the buffer layer can be, but is not limited to, silicone, latex or rubber.
[0035] It should be noted that the purpose of the sliding locking between the knob 6 and the bracket 5 is to enable the user to adjust the vertical sliding of the knob 6, and to lock and fix the knob 6 and the bracket 5 after the lower part of the knob 6 abuts against the upper limb. This can be achieved through various sliding locking mechanisms, such as the threaded connection between the screw 8 and the bracket 5 mentioned above, or it can be achieved by matching a slide groove and a plurality of card slots, that is, a vertical slide groove can be provided on the hole wall of the bracket 5 for the knob 6 to slide freely vertically, and a plurality of card slots are arranged in parallel along the length direction of the slide groove, and a card head is provided on the side wall of the knob 6, which can be respectively inserted into each card slot for locking and fixing, that is, after the lower part of the knob 6 abuts against the upper limb, the user can rotate the knob 6 to lock and fix the card head with the corresponding card slot.
