Description

Technical Field

[0001] This utility model relates to the field of radial artery postoperative care technology, and in particular to an arm restraint device after radial artery intervention. Background Technology

[0002] After radial artery intervention, patients need to lie flat and keep their arms naturally straight. During this period, patients need to avoid large movements of their arms, especially the wrist, to reduce the risk of vascular damage and bleeding.

[0003] Currently, the common practice is to use a grooved pillow to restrict the patient's arm movement. However, the pillow is easy to move on the mattress, and since it does not restrict the patient's forearm, the patient may unconsciously raise their forearm. Utility Model Content

[0004] The purpose of this invention is to provide an arm restraint device after radial artery intervention, thereby solving the aforementioned problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A radial artery interventional arm restraint device includes a headrest, an arm restraint cylinder, a telescopic rod, and a base plate. The arm restraint cylinder includes a pad and a U-shaped plate fixedly connected to the pad. The base plate is fixedly connected under the headrest. The extension direction of the U-shaped plate is perpendicular to the extension direction of the headrest. The base plate and the pad are movably connected by the telescopic rod. A strap is provided on the inner wall of the U-shaped plate at the end away from the headrest.

[0006] The beneficial effects of this utility model are as follows: because the patient's head is pressed on the headrest, the base plate is limited to be placed horizontally on the hospital bed, the base plate further limits the pad to be placed horizontally on the hospital bed, and the patient's forearm is limited to the U-shaped plate by the straps, the patient is ultimately unable to turn over and cannot raise the forearm. Using this device can keep the patient lying flat on the hospital bed and keep the arm naturally straight, reducing the risk of vascular damage and bleeding.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, it also includes a pin, and the telescopic rod includes a sleeve fixedly connected to one side of the base plate and an insert rod with one end slidably sleeved in the sleeve and the other end fixedly connected to the pad plate. The sleeve has an insertion hole corresponding to the pin, and the insert rod has multiple positioning holes spaced apart on its body corresponding to the insertion hole.

[0009] The further beneficial effects of the above are: by sliding the insert rod and adjusting the length of the insert rod extending out of the sleeve, the distance between the U-shaped plate and the headrest can be adjusted. After adjusting to a suitable distance and aligning the corresponding positioning hole with the insert hole, the pin is inserted into the insert hole and the corresponding positioning hole in sequence to lock the insert rod in the sleeve; the pin is easy to insert and remove, and the length of the telescopic rod is easy to adjust.

[0010] Furthermore, the sleeve is a square tube, and the corresponding insertion rod is a square rod.

[0011] The further beneficial effect of adopting the above is that the square surface has a large contact area, which avoids excessive stress concentration when the patient's upper arm presses on the telescopic rod, thus preventing the telescopic rod from breaking. Attached Figure Description

[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0015] Example 1 like Figures 1 to 2 As shown, a radial artery interventional arm restraint device includes a headrest 1, an arm restraint cylinder 2, a telescopic rod 3, and a base plate 4. The arm restraint cylinder 2 includes a pad 21 and a U-shaped plate 22 fixedly connected to the pad 21. The base plate 4 is fixedly connected to the bottom of the headrest 1. The extension direction of the U-shaped plate 22 is perpendicular to the extension direction of the headrest 1. The base plate 4 and the pad 21 are movably connected by the telescopic rod 3. A strap 23 is provided on the inner wall of the U-shaped plate 22 at the end away from the headrest 1.

[0016] The arm restraint device is placed on the hospital bed, and the patient is instructed to lie flat with their head resting on the headrest 1. The distance between the arm restraint cylinder 2 and the headrest 1 is adjusted using the telescopic rod 3. After adjusting to a suitable distance, the patient's forearm is placed in the U-shaped plate 22, and the back of the patient's wrist is tightly bound to the U-shaped plate 22 using the straps 23. Because the patient's head is pressed on the headrest 1, the base plate 4 is restrained and placed horizontally on the hospital bed. The base plate 4 is further restrained 21 and placed horizontally on the hospital bed. The patient's forearm is restrained by the straps 23 within the U-shaped plate 22. Ultimately, the patient cannot turn over, and the forearm cannot be raised. Using this device allows the patient to always lie flat on the hospital bed and keep the arm naturally straight, reducing the risk of vascular damage and bleeding.

[0017] In practice, the base plate 4 is laid flat on the bottom of the entire headrest 1.

[0018] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: It also includes pins 5. The telescopic rod 3 includes a sleeve 31 fixedly connected to one side of the base plate 4 and an insert rod 32 with one end slidably fitted inside the sleeve 31 and the other end fixedly connected to the pad plate 21. The sleeve 31 has an insertion hole 311 corresponding to the pin 5. The insert rod 32 has multiple positioning holes 321 spaced apart from the insertion hole 311 on its body. By sliding the insert rod 32, the length of the insert rod 32 extending out of the sleeve 31 is adjusted, thereby adjusting the distance between the U-shaped plate 22 and the headrest 1. After adjusting to a suitable distance and aligning the corresponding positioning holes 321 with the insertion holes 311, the pins 5 are inserted into the insertion holes 311 and the corresponding positioning holes 321 in sequence to lock the insert rod 32 inside the sleeve 31. The pins 5 are easy to insert and remove, making it easy to adjust the length of the telescopic rod 3.

[0019] The sleeve 31 is a square tube, and the corresponding insertion rod 32 is a square rod. This prevents the insertion rod 32 from rotating inside the sleeve 31, further ensuring that the pad 21 is always placed horizontally on the hospital bed. In practice, the insertion plate 32 is 10 cm wide and 0.5 cm thick, allowing the patient's arm to rest comfortably on it.

[0020] Example 3 This embodiment is a further improvement on embodiment 2, as detailed below: It also includes a U-shaped limiting ring 6, which is fixedly connected to the top of the pin 5. The U-shaped limiting ring 6 can be placed on the upper part of the patient's elbow joint to prevent horizontal swaying of the upper arm, thereby limiting the upper arm and further preventing arm swaying.

[0021] Strap 23 is a buckle-type strap. Buckle-type straps are easy to fasten and unfasten, saving time.

[0022] Example 4 This embodiment is a further improvement on embodiment 3, as detailed below: A raised pillow 13 is provided on the side of the headrest 1 closest to the telescopic rod 3. By placing the raised pillow 13 on the headrest 1, the headrest 1 is raised to meet the practical needs of different patients.

[0023] It also includes multiple inserts 7. The headrest 1 has a first adjustment groove 11 and a second adjustment groove 12 respectively on the inside of both sides. The multiple inserts 7 are movably inserted into the first adjustment groove 11 and the second adjustment groove 12. By inserting the inserts 7 into the first adjustment groove 11 and the second adjustment groove 12, the height of the front and back sides of the headrest 1 can be adjusted respectively, further fine-tuning the pillow surface height so that the pillow surface naturally conforms to the curve of the head and neck, making it more comfortable for the patient to lie flat.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
