Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a post-operative arm bracket. Background Art

[0002] Coronary stenting is a coronary interventional treatment technology developed on the basis of percutaneous intraluminal coronary angioplasty. After the tubular stent loaded on the PTCA balloon is delivered to the lesion through the radial artery, the balloon-type stent is expanded by pressurization and opened at the lesion. The stent is made of human-compatible, stainless steel memory alloy and has strong supporting capacity. After the stent is opened, the balloon can be deflated and withdrawn from the body. The stent will always remain at the lesion blood vessel to ensure the patency of the blood vessel and increase the blood supply to the myocardium.

[0003] After coronary stent surgery, the radial artery needs to be pressed to stop bleeding. During the process, the patient's arm needs to be placed flat on the bed. Since the bleeding time is relatively long, the patient's arm cannot be moved, which makes the patient's arm extremely uncomfortable and there is obvious soreness and swelling. Some patients even have swelling in the arms and backs of their hands. At present, in order to improve the comfort of patients, a layer of cotton wool is generally placed under the patient's arm to achieve the purpose of raising the patient's arm. However, the existing stent has a narrow force surface, and the patient's arm will generate pressure when placing it, and the arm cannot be cushioned. In addition, the length of the patient's arm is different, which is not convenient for patients to use in many aspects. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art, that is, the existing support has a narrow force-bearing surface, pressure is generated when the patient's arm is placed, the arm cannot be cushioned, and the lengths of patients' arms are different, making it inconvenient for patients to use it in many ways. A postoperative arm support is proposed to solve the shortcomings of the prior art, that is, the existing support has a narrow force-bearing surface, pressure is generated when the patient's arm is placed, the arm cannot be cushioned, and the arm lengths of patients are different, making it inconvenient for patients to use it in many ways.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A postoperative arm support, comprising: a base, a top of the base is rotatably connected to a threaded rod, an outer wall of the threaded rod is slidably connected to a sliding sleeve, an outer wall of the sliding sleeve is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a main board for supporting the arm;

[0007] A threaded sleeve, the threaded sleeve is threadedly connected to the outer wall of the threaded rod for adjusting the height of the mainboard, a spring is fixedly connected between the threaded sleeve and the sliding sleeve, the spring sleeve is arranged on the outer wall of the threaded rod, the outer wall of the threaded rod is sleeved with a damper, the top and bottom of the damper are respectively fixedly connected to the bottom of the sliding sleeve and the top of the threaded sleeve, and the spring is located inside the damper;

[0008] An extension mechanism is located on one side of the main board and is used to extend the main board.

[0009] Furthermore, the extension mechanism includes two support plates, both of which are fixedly connected to one side of the main board, an L-shaped connecting plate is rotatably connected between the two support plates, and one side of the L-shaped connecting plate is fixedly connected to a secondary plate;

[0010] A fixing component is located on the top of one of the support plates and is used to fix the rotated auxiliary plate.

[0011] Furthermore, the fixing assembly includes a plurality of card slots, and the plurality of card slots are all opened at the top of the L-shaped connecting plate, wherein the inner wall of one of the card slots is slidably connected with a card rod, and the other end of the card rod slides through one of the support plates and is fixedly connected with a fixing ring, and a tension spring is fixedly connected between the fixing ring and one of the support plates.

[0012] Furthermore, a telescopic rod is rotatably connected to the bottom of the main board, and a telescopic end of the telescopic rod is rotatably connected to the outer wall of the threaded sleeve.

[0013] Furthermore, a limiting ring for limiting the height is fixedly connected to the top of the threaded rod.

[0014] Furthermore, a soft pad is provided on the bottom inner wall of the mainboard.

[0015] In the present application, when in use, the bracket is first placed at the position where the patient needs to be placed, and then the threaded rod is rotated to make the threaded sleeve rise, thereby driving the spring and the damper sleeve to rise synchronously, thereby driving the telescopic rod and the main board to rise, and adjusting the height of the bracket. After adjusting the height of the bracket to a comfortable position for the patient, the patient can place the handle on the cushion to support the patient's handle. The pressure generated when the patient is placed will cause the main board to press down and slide, thereby driving the sleeve to slide, driving the telescopic rod to rotate and contract, the sliding of the slider drives the spring to contract, and the damper performs a damping effect, buffering the pressure of the patient's arm to avoid excessive pressure during placement affecting the patient. When the length of the main board needs to be extended, the card rod is pulled out of the card slot, so that the fixing ring rises, the tension spring is stretched, and then the L-shaped connecting plate is rotated to drive the sub-plate to rotate, so that the main board can be extended. After the rotation is completed, the card rod is released, the tension spring contracts, and the card rod is pulled into the card slot to fix the L-shaped connecting plate.

[0016] In the utility model, the postoperative arm support can buffer the patient's handle when it is placed through the arrangement of the sliding sleeve, the threaded sleeve, the damper and the spring, so as to avoid excessive pressure during placement to affect the patient, thereby affecting the recovery state of the patient's arm;

[0017] In the utility model, the postoperative arm support can extend the main board through the cooperation of the L-shaped connecting plate and the auxiliary board, so as to be suitable for patients with different arm lengths, facilitate the multi-directional application of the patients, and increase the practicality of the support;

[0018] In the utility model, the sliding sleeve, the threaded sleeve, the damper and the spring provide buffering for the patient's handle when it is placed, so as to avoid excessive pressure on the patient when placed; the L-shaped connecting plate and the auxiliary plate extend the main plate, which is suitable for patients with different arm lengths, is convenient for the patient's multi-directional use, and increases the practicality of the bracket.
