Description

Technical Field

[0001] This utility model relates to the field of brachial artery fixation technology, specifically to brachial artery fixation braces after cardiovascular interventional procedures. Background Technology

[0002] Cardiac interventional therapy is a novel diagnostic and treatment technique for cardiovascular diseases. It does not require open-chest surgery. Under the guidance of imaging methods, a catheter is inserted through a puncture of a superficial blood vessel and, with the aid of certain instruments, is delivered to the lesion site. Through specific cardiac catheterization techniques, it is a method for diagnosing and treating heart disease. It is a relatively advanced method for the diagnosis and treatment of heart disease, and its development is very rapid. It lies between medical treatment and surgical treatment. It is an invasive diagnostic and treatment method. After a cardiovascular interventional procedure, patients who have returned home usually need to have their brachial artery fixed to prevent bleeding and hematoma at the puncture site.

[0003] In some cardiovascular interventional procedures, the brachial artery is fixed using a cardboard box to prevent the elbow from bending. However, this method cannot be adjusted to provide a comfortable fit based on the length of the patient's upper and lower arm. Therefore, it does not meet the current needs. To address this, we propose a brachial artery fixation brace for cardiovascular interventional procedures. Utility Model Content

[0004] The purpose of this invention is to provide a brachial artery fixation brace after cardiovascular interventional procedures to solve the problem mentioned in the background art, where brachial artery fixation after cardiovascular interventional procedures usually involves using a cardboard box to fix the elbow joint and prevent bending, but it cannot be adjusted to a suitable comfort according to the length of the patient's upper arm and forearm.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brachial artery fixation brace after cardiovascular interventional surgery, comprising an upper arm seat and a forearm seat. A connecting groove is provided at the bottom end of one side of the upper arm seat, and one end of the forearm seat is slidably connected to the inside of the connecting groove. Slide rails are provided on both sides of the forearm seat, and sliders that are slidably connected to the slide rails are fixedly connected to both sides of the inner wall of the connecting groove. A strap is connected to one side of both the upper arm seat and the forearm seat. A pad is fixedly connected to the upper end of both the upper arm seat and the forearm seat. A groove is provided on the upper end of the forearm seat away from the pad and close to the upper arm seat.

[0006] Preferably, the upper arm seat has through slots on both sides near the lower arm seat and above the connecting slot, and pressing blocks are slidably connected inside the through slots on both sides.

[0007] Preferably, each of the two pressing blocks has a sliding groove on the side where they are close to each other, and a crossbar extending into the sliding groove is fixedly connected to the inner wall of the side where the two through grooves are close to each other. A limiting plate that is slidably connected to the sliding groove is fixedly connected to the end of the crossbar located inside the sliding groove.

[0008] Preferably, each of the two pressing blocks has a spring connected to the inner wall of the through groove on the side that is close to each other, and the spring is wound around the outer surface of the crossbar.

[0009] Preferably, the bottom ends of the two pressing blocks on the side closest to each other are each connected by a limiting block that extends through the connecting groove via a connecting rod.

[0010] Preferably, the groove and the connecting groove are connected in a continuous manner, and a plurality of isosceles trapezoidal limiting grooves are provided at equal intervals on both sides of the inner wall of the groove, and the limiting block is inserted into the corresponding limiting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes the pinching of the pressing blocks on both sides of the upper arm seat to cause them to slide closer along the outer surface of the crossbar, compressing the spring and causing the limiting block to disengage from its current limiting groove and move to the center of the groove. This releases the connection between the upper arm seat and the forearm seat. Then, the upper arm seat slides to one side of the forearm seat, allowing adjustment of the length between them. After adjustment, releasing the pressing of the pressing blocks releases the spring's elastic force, pushing the pressing blocks to move the limiting block away from each other and engaging it with the corresponding limiting groove, thus fixing the connection between the upper arm seat and the forearm seat. This allows for adjustment of the distance between the upper arm seat and forearm seat according to the patient's upper and lower arm lengths, improving patient comfort. After adjustment, the patient places their upper and lower arms on the soft pads provided by the upper and lower arm seats post-surgery, and then secures the arm with a strap to prevent elbow bending.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 3 This utility model provides an embodiment of a brachial artery fixation brace after cardiovascular intervention, including an upper arm seat 1 and a forearm seat 2. A connecting groove 101 is provided at the bottom end of one side of the upper arm seat 1. One end of the forearm seat 2 is slidably connected to the inside of the connecting groove 101. Slide rails 201 are provided on both sides of the forearm seat 2, and sliders that are slidably connected to the slide rails 201 are fixedly connected to both sides of the inner wall of the connecting groove 101. A strap 4 is connected to one side of both the upper arm seat 1 and the forearm seat 2. A soft pad 3 is fixedly connected to the upper end of both the upper arm seat 1 and the forearm seat 2. After the operation, the patient places the upper arm and forearm on the soft pad 3 of the upper arm seat 1 and the forearm seat 2, and then binds the arm tightly with the strap 4 to prevent the elbow joint from bending. A groove 202 is provided at the upper end of the forearm seat 2 away from the soft pad 3 and close to the upper arm seat 1.

[0016] On both sides of the upper arm base 1 near the lower arm base 2, and above the connecting groove 101, there are through grooves 102 that are connected to the connecting groove 101. Pressing blocks 6 are slidably connected inside the through grooves 102 on both sides. A sliding groove 601 is opened inside the side of the two pressing blocks 6 that are close to each other. A crossbar 7 extending into the sliding groove 601 is fixedly connected to the inner wall of the side of the two through grooves 102 that are close to each other. A limiting plate 8 that is slidably connected to the sliding groove 601 is fixedly connected to the end of the crossbar 7 that is inside the sliding groove 601. A spring 9 is connected between the side of the two pressing blocks 6 that are close to each other and the inner wall of the through groove 102. The spring 9 is wrapped around the outer surface of the crossbar 7. A limiting block 10 extending into the connecting groove 101 is connected to the bottom end of the side of the two pressing blocks 6 that are close to each other through a connecting rod.

[0017] By pinching the pressing blocks 6 on both sides of the upper arm seat 1, the pressing blocks 6 on both sides slide close to each other along the outer surface of the crossbar 7 and compress the spring 9, thereby causing the limiting block 10 to disengage from the current limiting groove 5 and move to the middle of the groove 202. Then the connection limit between the upper arm seat 1 and the forearm seat 2 can be released. Then, the upper arm seat 1 is slidably connected to the forearm seat 2 on one side, thereby adjusting the length between the upper arm seat 1 and the forearm seat 2.

[0018] The groove 202 is connected to the connecting groove 101. Several isosceles trapezoidal limiting grooves 5 are equally spaced on both sides of the inner wall of the groove 202. The limiting block 10 is inserted into the corresponding limiting groove 5. After the length between the upper arm seat 1 and the forearm seat 2 is adjusted, the pressing of the pressing blocks 6 on both sides is released. At this time, the spring 9 releases its elastic force, thereby pushing the pressing blocks 6 on both sides to move the limiting block 10 to the side away from each other, so that the limiting block 10 is inserted into the corresponding limiting groove 5, and the connection between the upper arm seat 1 and the forearm seat 2 is fixed. Thus, the distance between the upper arm seat 1 and the forearm seat 2 can be adjusted according to the length of the patient's upper arm and forearm, thereby improving the patient's comfort.

[0019] When using the brachial artery fixation brace after cardiovascular interventional surgery, by pinching the pressing blocks 6 on both sides of the upper arm seat 1, the pressing blocks 6 on both sides slide closer along the outer surface of the crossbar 7, compressing the spring 9, which in turn causes the limiting block 10 to disengage from the current limiting groove 5 and move to the middle of the groove 202. Then, the connection between the upper arm seat 1 and the forearm seat 2 can be released. Next, by sliding one side of the upper arm seat 1 to one side of the forearm seat 2, the length between the upper arm seat 1 and the forearm seat 2 can be adjusted. After adjustment, release the pressing blocks 6 on both sides. At this time, the spring 9 releases its elastic force, thereby pushing the pressing blocks 6 on both sides to move the limiting blocks 10 to the side away from each other, and making the limiting blocks 10 insert into the corresponding limiting grooves 5, connecting and fixing the upper arm seat 1 and the forearm seat 2. This allows the distance between the upper arm seat 1 and the forearm seat 2 to be adjusted according to the length of the patient's upper arm and forearm, improving the patient's comfort. After the upper arm seat 1 and the forearm seat 2 are adjusted, the patient places the upper arm and forearm on the soft pads 3 of the upper arm seat 1 and the forearm seat 2 after surgery, and then uses the straps 4 to tie the arm tightly and fix it, preventing the elbow joint from bending.
