Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a lumbar support auxiliary device. Background Art
[0002] During radiotherapy (abbreviated as RT), patients are required to maintain a stable treatment position for a long time. For patients with thin stature, especially when treating tumors involving the waist area, they often face a significant technical challenge. Due to the patient's body shape, the waist area is prone to being suspended during radiotherapy. The suspended waist not only increases the patient's physical burden, but is also prone to position deviation due to factors such as breathing and muscle tension, which in turn causes positioning errors and reduces the accuracy of radiotherapy. Utility Model Content

[0008] In at least one embodiment, a protective film is disposed directly above the coil spring, and two sides of the protective film are respectively connected to two ends of the bottom plate.
[0009] In at least one embodiment, the lower surface of the bottom plate is provided with several anti-slip stickers.

[0019] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.
[0020] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.
[0021] like Figures 1 to 4As shown, the lumbar support auxiliary device of the embodiment of the present application includes a base plate 1 and a spreading mechanism 2. The spreading mechanism 2 is horizontally mounted in the middle area of the base plate 1 and is arranged parallel to the width direction of the base plate 1. The spreading mechanism 2 includes a support seat 21, a rotating shaft 22 and a coil spring 23. Two support seats 21 are provided, and are respectively arranged on the two side edges of the base plate 1 opposite to each other. The rotating shaft 22 can pass through the support seat 21 and be rotatably arranged between the two support seats 21. The outer surface of the support seat 21 is penetrated by an internal threaded connection with a fixing bolt 24 for limiting the rotation of the rotating shaft 22; the coil spring 23 is sleeved on the outer surface of the rotating shaft 22, the inner end of the coil spring 23 is fixedly connected to the outer surface of the rotating shaft 22, and the outer end of the coil spring 23 is fixedly connected to the base plate 1 directly below the rotating shaft 22.
[0022] Among them, the lumbar support auxiliary device in this embodiment can be set to three specifications: small, medium and large, so that it can be used according to the body shapes of different patients. When in use, the width of the lumbar support auxiliary device should be selected to be less than or equal to the width of the patient's body, so as to facilitate subsequent medical staff to fix the patient's position.
[0023] In order to facilitate medical personnel to rotate the rotating shaft 22 , a butterfly handle 25 is fixedly connected to one end of the rotating shaft 22 .
[0024] The width of the coil spring 23 is equal to the length of the rotating shaft 22. By arranging in this way, the contact area between the patient and the coil spring 23 can be increased, and the formation of pressure sores can be effectively prevented.
[0025] A protective film 3 is arranged just above the coil spring 23, and the two sides of the protective film 3 are detachably connected to the two ends of the bottom plate 1 by Velcro. The design of the protective film 3 not only protects the coil spring 23 from external pollution and damage, but also has a certain air permeability, avoiding the discomfort that may be caused by the coil spring 23 contacting the skin for a long time. At the same time, the protective film 3 can be detached and cleaned, which is convenient for repeated use, improving the practicality and economy of the device.
[0026] In addition, several anti-slip stickers 4 are provided on the lower surface of the base plate 1. The design of the anti-slip stickers 4 increases the friction between the device and the radiotherapy frame, preventing the device from sliding due to slight movement of the patient during radiotherapy, and further improving the stability and safety of radiotherapy.
[0027] The method of using the waist support auxiliary device is as follows: first, the medical staff places the waist support auxiliary device in the suspended area below the patient's waist, and then adjusts the opening degree of the expansion mechanism 2 according to the actual body shape of the patient. The specific operation is to hold the butterfly handle 25 and rotate the shaft 22 clockwise or counterclockwise. Since the coil spring 23 has an elastic restoring force, after the coil spring 23 is unfolded and contacts the patient's body, tighten the fixing bolt 24 to lock the position of the shaft 22. At this time, the flexible support of the coil spring 23 gently lifts the patient's waist, effectively avoiding the situation where the waist is suspended in the air, reducing the patient's physical burden and discomfort, and ensuring that the coil spring 23 of the expansion mechanism 2 remains stable during radiotherapy. During treatment, medical staff can regularly check whether the patient's body position is stable. If necessary, they can adjust the opening degree of the coil spring 23 again to ensure the accuracy of radiotherapy.
[0028] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
