Description

Technical Field

[0001] This utility model relates to the field of exercise for radiotherapy patients, specifically an auxiliary exercise device for radiotherapy patients. Background Technology

[0002] Radiation therapy causes atrophy and fibrosis of the masticatory muscles, leading to difficulty opening the mouth. Prevention is key; patients should perform mouth-opening exercises during radiation therapy. Chinese utility model patent application number 202420371052.9 discloses a fully automatic mouth-opening exercise device for radiation therapy patients, comprising two closed rings hinged at their right ends. A sliding groove is formed on the upper surface of the right end of the lowermost closed ring. The left ends of both closed rings are flipped in opposite directions, and an arc-shaped incomplete toothed ring is fixedly connected to the right end of the uppermost closed ring.

[0003] The aforementioned fully automatic mouth-opening training device for radiotherapy patients, through its incomplete arc-shaped gear ring and gears, enables the incomplete arc-shaped gear ring to rotate downwards or upwards when the power shaft rotates forwards or backwards, achieving the effect of automatic opening and closing of two closed rings. This facilitates mouth-opening training for users. Furthermore, the included display controller allows users to easily preset training time, opening frequency, and angle, assisting patients in scientifically and accurately completing mouth-opening training courses and improving overall practicality. However, a defect was discovered during use: a horizontal block 3 is located at the front end of its closed ring, such as... Figure 1 As shown, the front end of the transverse block 3 has a boss 31, and the rear end of the transverse block 3 is fixedly connected to the front end of the closing ring 32. In use, the patient bites on the transverse block. Because the width of the transverse block is relatively small, when the patient bites, the transverse block only contacts a few teeth on the upper and lower sides, which is very uncomfortable; although there is a rubber pad, it is very thin and has very limited softness. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an auxiliary exercise device for radiotherapy patients. This auxiliary exercise device can increase the contact area with the patient's upper and lower teeth, and can increase softness and comfort, effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary exercise device for radiotherapy patients, comprising a malleable biting part, wherein the biting part has an arc-shaped structure and a groove that runs through the left and right sides at the front and rear middle positions;

A through hole that coincides with the screw hole is provided on the horizontal block. A fastening bolt that matches the screw hole is screwed from the outside to the inside at the through hole.

[0007] As a preferred technical scheme, the holding part comprises a silica gel block, and a moldable metal rod is arranged in each of the silica gel blocks on the two sides of the groove.

[0008] As a preferred technical scheme, vertical cutting surfaces of the silica gel blocks on the two sides of the groove are in an upper-convex arc structure.

[0009] As a preferred technical scheme, a connecting rib is further arranged between the metal rod and the lower fixing block.

[0010] As a preferred technical scheme, the rear end of the fixing block is further provided with a limiting structure matched with the front end of the closed ring.

[0011] As a preferred technical scheme, the limiting structure comprises clamping blocks fixed to the left and right sides of the rear end surface of the fixing block.

[0012] As a preferred technical scheme, the inner surface of the clamping block is in sliding fit with the left and right side surfaces of the rear side of the horizontal block.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] like Figures 2 to 4 As shown, an auxiliary exercise device for radiotherapy patients includes a malleable biting part 1 with an arc-shaped structure and a through groove 11 at the front-to-back center. A fixing block 2 is fixed to the bottom surface of the biting part 1 in a front-to-back direction. A blind hole 21, which engages with the front protrusion 31 of a horizontal block 3, is embedded on the front side of the bottom of the fixing block 2. A screw hole 22 is located at the center of the fixing block 2. A through hole 33, which overlaps with the screw hole 22, is provided on the horizontal block 3. A fastening bolt 34, which engages with the screw hole 22, is screwed into the through hole 33. The fixing block 2 and the horizontal block 3 are thus fixedly connected together.

[0027] The biting part 1 includes a silicone block 12, and a malleable metal rod 13 (iron rod) is inserted into the silicone block 12 on both sides of the groove 11.

[0028] The silicone blocks 12 on both sides of the groove 11 have an upward-convex arc-shaped structure in their vertical cross-section, which helps to protect the patient's mouth.

[0029] A connecting rib 23 is also fixed (welded) between the metal rod 13 and the fixing block 2 (metal block) below it to enhance the strength.

[0030] In use, the bite-holding part 1 is installed on the horizontal block 3 of the mouth-opening exerciser mentioned in the background art (a bite-holding part 1 is installed on the upper side of the upper horizontal block 3, with the groove 11 of the bite-holding part 1 facing upwards; a bite-holding part 1 is installed on the lower side of the lower horizontal block 3, with the groove 11 of the bite-holding part 1 facing downwards). The groove 11 facilitates the interlocking and occlusion of the patient's teeth, and the bite-holding part 1 can be bent to change its shape and adjust the comfort of use. The silicone block 12 is relatively soft and can effectively improve the patient's bite comfort, while the metal rod 13 facilitates the changing shape of the silicone block 12. The bite-holding part 1 is fixedly connected to the horizontal block 3 by the fixing block 2 and the fastening bolt 34. The left and right width of the fixing block 2 is small, which facilitates the bending and adjustment of the curvature of the bite-holding part 1. Example 2

[0031] like Figure 5 As shown, the rear end of the fixing block 2 is also provided with a limiting structure that cooperates with the arc-shaped part of the closing ring 32. The limiting structure includes locking blocks 24 (rearwardly extending cuboids) fixed to the left and right sides of the rear end face of the fixing block 2.

[0032] The inner surface of the locking block 24 slides with the left and right sides of the closing ring 32 behind the horizontal block 3.

[0033] When in use, the locking block 24 can be locked at the front end of the closing ring 32 on the rear side, which helps to limit the fixing block 2 and improves the overall stability.
