Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, and specifically refers to a brachial artery compression fixator. Background Technique
[0002] With the development of interventional cardiology, clinical interventional therapy has rapidly become an effective diagnostic method and treatment means. Minimally invasive interventional surgeries in vascular surgery and neurosurgery, when dealing with some complex diseases, such as patients with aortic dissection, carotid artery stenosis or occlusion, and lower extremity artery stenosis or occlusion, especially some patients with vascular anatomical morphological variations, need to use brachial artery puncture as the surgical approach. Currently, there is no special arm fixation and compression hemostasis device after brachial artery puncture in clinical practice. After brachial artery puncture, patients often have involuntary arm bending, which will increase the occurrence of bleeding at the puncture site, subcutaneous congestion, and postoperative complications such as brachial artery pseudoaneurysm. The immobilization of the arm restricts the activities of patients, greatly prolongs the bed rest and upper limb immobilization time after interventional surgery, and increases the probability of deep vein thrombosis after surgery.
[0003] Currently, there are only compression hemostasis devices applied to the femoral artery and radial artery on the market, but the femoral artery and radial artery hemostasis devices cannot be applied to the brachial artery because the elbow joint of the upper limb has a large range of activities, and the size and fixation method of the femoral artery and radial artery compression hemostasis devices do not conform to the elbow joint. Clinically, elastic bandages are currently only used for compression hemostasis, which has various defects, and the main clinical manifestations are as follows:
[0004] 1. The compression intensity of the elastic bandage varies, and too tight compression will lead to upper limb ischemia, even finger tip ischemia necrosis, upper limb venous return disorder, and swelling; too loose compression cannot effectively stop bleeding, resulting in upper limb hematoma, massive bleeding, and even brachial artery pseudoaneurysm, hemorrhagic shock, etc.
[0005] 2. Most patients need anticoagulant or antiplatelet treatment after brachial artery puncture point approach surgery. The elastic bandage cannot restrict the activities of the upper limb. After the operation, many patients' involuntary upper limb activities cause ineffective compression hemostasis, resulting in delayed bleeding at the puncture point and the occurrence of pseudoaneurysm.
[0006] Therefore, a brachial artery compression fixator is proposed to solve the current deficiencies. Content of the Utility Model
[0007] The technical problem to be solved by the utility model is to overcome the above-mentioned technical defects and provide a brachial artery compression fixator.
[0008] To solve the above-mentioned technical problem, the technical solution provided by the utility model is a brachial artery compression fixator: including an elbow support and a limit plate;
[0009] The elbow rest is of a rectangular structure. A plurality of limiting plates are arranged in parallel and at intervals inside the elbow rest. A plurality of elastic bands are connected to one side of the elbow rest, and the other ends of the elastic bands are connected with hook parts of Velcro. The other end of the elbow rest is connected with an elastic breathable band, and the other end of the elastic breathable band is connected with a loop part of Velcro that can be movably connected with the hook part of Velcro;
[0010] A breathable sponge cushion layer is arranged on the inner side of the elbow rest.
[0011] As an improvement, the elbow rest is sewn from a double-layer flexible material, and the limiting plates are sewn inside the elbow rest.
[0012] As an improvement, the limiting plates are rectangular, and the limiting plates are arranged along the length direction of the elbow rest and their two ends extend to the two ends of the elbow rest.
[0013] As an improvement, the number of the limiting plates is three.
[0014] As an improvement, it further includes an identification area, and the identification area is arranged on the side of the elbow rest away from the breathable sponge cushion layer.
[0015] The advantages of the present utility model compared with the prior art are as follows:
[0016] 1. Through the cooperation between the elbow rest and the limiting plates, the wrapping and fixation of the patient's arm can be realized. At the same time, the phenomenon of involuntary arm bending of the patient can be avoided. And through the setting of the elastic bands, the elastic breathable band and Velcro, it is convenient to wear and the adjustment of the fixation tightness can be realized;
[0017] 2. The fixing band has a simple structure and is convenient to use. At the same time, it is convenient to cooperate with a hemostatic device. While realizing the compression hemostasis of the patient, the phenomenon of involuntary arm bending of the patient after brachial artery puncture can be avoided, the safety after the operation is improved, the time of the patient staying in bed and the upper limb being immobilized after the interventional operation is shortened, and the probability of postoperative deep vein thrombosis is reduced.

[0029] Combined with the attached Figures 1-5As shown in the figure, a brachial artery compression fixator includes an elbow rest 1 and a limiting plate 2;
[0030] Specifically, the elbow rest 1 is of a rectangular structure and is sewn from double-layer flexible materials. During implementation, the elbow rest 1 can effectively wrap the patient's arm. At the same time, it can ensure the comfort of the patient's arm during compression. At the same time, the elbow rest 1 is made of breathable materials, which can ensure breathability while realizing the compression and fixation of the arm, avoiding stuffiness at the arm.
[0031] Similarly, the elbow rest 1 can also be made of hard materials with a semi-circular cross-section and is adapted to the arm, realizing the wrapping and fixation of the arm while preventing involuntary arm bending after the patient's brachial artery puncture.
[0032] A plurality of limiting plates 2 are arranged in parallel and at intervals inside the elbow rest 1. The limiting plates 2 are sewn inside the elbow rest 1 to realize the fixed setting of the limiting plates 2 inside the elbow rest 1. At the same time, the limiting plates 2 are made of hard materials. In this embodiment, the limiting plates 2 are made of metal materials.
[0033] Specifically, the limiting plate 2 is rectangular, and the limiting plate 2 is arranged along the length direction of the elbow rest 1 and its two ends extend to both ends of the elbow rest 1. During specific implementation, through the setting of the limiting plate 2 inside the elbow rest 1, while ensuring the curling of the elbow rest 1 in the transverse direction, the curling of the elbow rest 1 in the longitudinal direction can be avoided, and thus, while wrapping and fixing the arm, the phenomenon of involuntary arm bending after the patient's brachial artery puncture can be prevented.
[0034] The number of the limiting plates 2 can be set according to actual situations. In this embodiment, the number of the limiting plates 2 is 3. At the same time, the middle limiting plate 2 is located in the middle of the elbow rest 1, and the other two limiting plates 2 are located on both sides of the middle limiting plate 2 and are symmetrically arranged. During specific implementation, there is a certain distance between adjacent limiting plates 2, which can facilitate the wrapping of the elbow rest 1 around the arm. At the same time, through the fitting setting of the limiting plates 2 and the arm, the straight-line fixation of the arm can be realized.
[0035] A plurality of elastic bands 3 are connected to one side of the elbow rest 1. The plurality of elastic bands 3 are arranged along the length direction of the elbow rest 1, and the plurality of elastic bands 3 are arranged in parallel and at intervals;
[0036] The other end of the elastic band 3 is connected to a hook part 4 of a magic tape. The other end of the elbow rest 1 is connected to an elastic breathable band 5, and the other end of the elastic breathable band 5 is connected to a loop part 6 of a magic tape that can be movably connected to the hook part 4 of the magic tape;
[0037] In specific implementation, the connection between the hook part 4 of the Velcro and the elbow rest 1 is realized through the elastic band 3. While wrapping the patient's arm, the adjustment of the wrapping tightness can be achieved to ensure the comfort of the fixator when fixing the patient's arm. At the same time, the connection between the loop tape 6 of the Velcro and the elbow rest 1 is realized through the elastic breathable band 5. And through the cooperation with the elastic band 3, the wrapping of arms with different thicknesses can be achieved, and at the same time, the use requirement of adjusting the tightness can be met. Moreover, through the cooperative setting of the hook part 4 of the Velcro and the loop tape 6 of the Velcro, it is convenient for the fixator to be worn and removed on the patient's arm.
[0038] A breathable sponge cushion layer 7 is provided inside the elbow rest 1. The breathable sponge cushion layer 7 is adapted to the elbow rest 1. When wrapping the patient's arm, the breathable sponge cushion layer 7 contacts the patient's arm, which can ensure the comfort of its use.
[0039] It further includes an identification area 8. The identification area 8 is arranged on the side of the elbow rest 1 away from the breathable sponge cushion layer 7. During implementation, the identification area 8 can be used to identify patient information and the start time of compression, which is convenient for medical staff to view the information.
[0040] When the present utility model is specifically implemented, the elbow rest 1 wraps the patient's arm. At this time, the limiting plate 2 located in the middle position in the elbow rest 1 is correspondingly arranged with the elbow of the patient's arm. At the same time, the limiting plates 2 on both sides are in contact with both sides of the arm. Meanwhile, through the cooperative setting of the hook part 4 of the Velcro and the loop tape 6 of the Velcro, the wrapping and fixing of the fixator on the arm can be realized. And during the use process, through the connection at different positions between the hook part 4 of the Velcro and the loop tape 6 of the Velcro, and in cooperation with the settings of the elastic band 3 and the elastic breathable band 5, the adjustment of the fixing tightness can be achieved.
[0041] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose of the present utility model, they design similar structural manners and embodiments to this technical solution without creative efforts, which shall fall within the protection scope of the present utility model.
