Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical surgical auxiliary device technology, specifically to a lateral decubitus lower limb embedded positioning device. Background Technology
[0002] Lateral decubitus positioning is a common patient placement method suitable for various medical scenarios, including surgery, examination, and treatment. Currently, in various lateral decubitus surgical procedures, many hospitals do not have dedicated lower limb lateral decubitus pads, often using cotton blankets to elevate the upper lower limb, while some hospitals use homemade soft pillows. However, the inventors of this application have observed through clinical work that existing lateral decubitus positioning requires multiple cotton blankets or soft pillows, which is cumbersome and affects the efficiency of surgical procedures. If used improperly, the upper lower limb may slip and shift during surgery, causing accidental damage to the patient's nerves, muscles, and other tissues. At the same time, lateral decubitus positioning makes it more difficult to effectively warm the patient's lower limb, increasing the incidence of hypothermia and deep vein thrombosis. Utility Model Content
[0003] To address the existing problems of requiring multiple blankets or soft pillows for lateral decubitus positioning, which is cumbersome and affects the efficiency of surgical procedures, and the possibility that improper use may cause the upper lower limb to slip and shift during surgery, resulting in accidental damage to the patient's nerves, muscles and other tissues, as well as the difficulty in effectively warming the lower limb after lateral decubitus positioning, which increases the incidence of hypothermia and deep vein thrombosis, this utility model provides a lateral decubitus lower limb embedded positioning device.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A lateral lower limb embedded positioning device includes a grooved support frame and an air supply duct. The grooved support frame includes a top support plate, a first support side plate, and a second support side plate. The first and second support side plates are fixedly connected to the two opposite long sides of the top support plate. The surface of the grooved support frame is covered with memory foam, and the surface of the memory foam is covered with a leather sleeve. The air supply duct is tightly wrapped with the memory foam and the leather sleeve at the corner connection between the inner surface of the top support plate and the first or second support side plate. The wall of the air supply duct is provided with multiple air supply holes. One end of the air supply duct is a closed end, and the other end is an open end used as an air inlet. The leather sleeve is provided with multiple ventilation holes opposite to the air supply duct.
[0006] Compared with existing technologies, the lateral decubitus lower limb embedded positioning device provided by this utility model allows the patient to first place one lower limb in the groove of the groove-shaped support frame, and then place the other lower limb on the support top plate of the groove-shaped support frame. This lateral decubitus positioning is more standardized, simple, convenient, safe and effective, and can meet the needs of various lateral decubitus surgical positioning. It keeps the patient's lower limb in a functional position and can effectively prevent pressure injury and nerve damage. Then, the open end of the air supply pipe is connected to the hot air pipe of the external heating device. The hot air heated by the heating device is delivered to the air supply pipe through the hot air pipe. Then, the air passes through multiple air supply holes on the air supply pipe, memory foam and ventilation holes on the leather sleeve to effectively warm the patient's lower limb (the lower limb in the groove of the groove-shaped support frame), reducing the incidence of intraoperative hypothermia and deep vein thrombosis. Therefore, the lateral decubitus lower limb embedded positioning device provided in this application can greatly shorten the lateral decubitus positioning time, put the patient in a comfortable and correct surgical position, effectively improve the success rate of surgery, reduce the occurrence of complications, and effectively warm the patient's lower limbs, reducing the incidence of intraoperative hypothermia and deep vein thrombosis. It has high clinical applicability.
[0007] Furthermore, the grooved support frame is made of acrylic material in one piece.
[0008] Furthermore, the grooved support frame has a length of 63-65cm, a width of 33-35cm, and a height of 18-20cm.
[0009] Furthermore, the diameter of the air supply duct is 5-6 cm, and the air supply duct is made of tubular sponge. Attached Figure Description
