Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an arm placement rack for a deep tumor hyperthermia treatment bed. Background Technology

[0002] Currently used deep hyperthermia systems (endophytic field tumor hyperthermia systems) in clinical practice require precise targeting of the tumor site during treatment to avoid damage to surrounding healthy tissues. Therefore, patients must keep both upper limbs raised throughout the treatment, placing them outside the treatment area. The treatment bed also lacks support for the patient's upper limbs. Furthermore, since deep hyperthermia treatment typically lasts around 60 minutes, patients often experience muscle tension or nerve compression in their upper limbs after treatment, leading to significant soreness and discomfort, increasing their suffering. Additionally, some elderly patients have limited upper limb raising ability, or patients with frozen shoulder are unable to raise their arms. This lack of support prevents the use of deep hyperthermia for the upper limbs. Utility Model Content

[0003] The purpose of this invention is to provide an arm placement frame for a deep hyperthermia treatment bed for tumors. By setting a multi-directionally adjustable arm placement frame at the head of the treatment bed, it can provide support for the patient's upper limbs during treatment and adapt to the differences in arm length and joint mobility of patients of different body types, thus avoiding muscle tension or nerve compression.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A deep hyperthermia treatment bed arm placement frame for tumors includes a treatment bed body and an upper limb bending adapter bracket. There are two upper limb bending adapter brackets, which are slidably installed below one end of the treatment bed body. Each upper limb bending adapter bracket includes a first support arm and a second support arm. The first support arm is slidably connected to the treatment bed body, and the other end of the first support arm is rotatably connected to the second support arm.

[0006] An arm support bracket is installed on the outside of a first support arm and a second support arm. The arm support bracket includes two sliding collars and two arm supports. The arm supports are installed on the top of the sliding collars, and the two sliding collars are respectively slidably installed on the outside of the first support arm and the second support arm.

[0007] Furthermore, a sliding groove is provided at the bottom of one end of the treatment bed, and a slider is slidably installed inside the sliding groove. A second deflection motor is fixed at the bottom of the slider. The output end of the second deflection motor is fixed to one end of the first support arm, and a first deflection motor is fixed to the other end of the first support arm. The output end of the first deflection motor is fixed to one end of the second support arm.

[0008] Furthermore, a ball shaft is fixed to the top of the sliding collar, and a bushing is fixed to the bottom of the arm support. The ball shaft is located inside the bushing, and the bushing is rotatably connected to the ball shaft.

[0009] Furthermore, the bottom of the sliding collar is threadedly connected to a threaded knob, and a locking plate is rotatably mounted on the top of the threaded knob. The locking plate is located at the bottom of the inner side of the sliding collar.

[0010] Furthermore, limit rings are fixed to the outer ends of both ends of the first support arm and the second support arm.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This utility model uses a sliding groove and a slider to link together, and combines a second deflection motor to control the horizontal deflection of the first support arm and the first deflection motor to control the vertical deflection of the second support arm, forming a multi-dimensional adjustment that can adapt to the patient's shoulder width, shoulder flexion range and hand flexion range. It also supports the forearm and forearm through the arm support, significantly improving the upper limb support adaptability during treatment.

[0013] This invention uses a bushing that links with a ball joint and an elastic support cloth to adaptively wrap the elbow. While ensuring support stability, it allows the patient's upper limb to make minor adjustments, avoiding discomfort caused by stiffness due to a completely fixed upper limb position during treatment.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1 to 4 As shown, a deep hyperthermia treatment bed arm placement frame for tumors includes a treatment bed 1 and an upper limb bending adapter bracket 2. There are two upper limb bending adapter brackets 2, which are slidably installed below one end of the treatment bed 1. The upper limb bending adapter bracket 2 includes a first support arm 21 and a second support arm 22. The first support arm 21 is slidably connected to the treatment bed 1, and the other end of the first support arm 21 is rotatably connected to the second support arm 22.

[0022] Arm support 3 is installed on the outside of the first support arm 21 and the second support arm 22. The arm support 3 includes two sliding collars 31 and two arm supports 32. The arm supports 32 are installed on the top of the sliding collars 31. The two sliding collars 31 are respectively slidably installed on the outside of the first support arm 21 and the second support arm 22.

[0023] In use, the patient lies on the treatment bed 1 with their head facing the side where the upper limb flexion adapter 2 is installed. The patient raises their arm to a comfortable position that does not interfere with deep heat therapy. The upper limb flexion adapter 2, installed at one end of the treatment bed 1, is then slid down to the patient's forearm. The angle between the first support arm 21 and the second support arm 22 is adjusted according to the patient's raised arm position to accommodate the range of elbow flexion. The patient's forearm and forearm rest on the arm rests 32 installed above the first and second support arms 21 and 22, respectively. The elastic support fabric 33 is elastic and can... The arm support 32 is designed to accommodate the bending angles of the first support arm 21 and the second support arm 22 while also providing support for the patient's elbow. The sliding collar 31 has the function of sliding and rotating on the first support arm 21 and the second support arm 22, which can adjust the position and installation angle of the arm support 32 to accommodate more arm positions. The elastic support cloth 33 can also be adjusted according to the position of the arm support 32. Through the arm support 32 and the elastic support cloth 33, the patient's arm can be better supported and adapted to different positions, ensuring the patient's comfort during treatment.

[0024] Please refer to the following: Figure 2 and Figure 3As shown, a sliding groove 11 is provided at the bottom of one end of the treatment bed 1. A slider 25 is slidably installed inside the sliding groove 11. A second deflection motor 24 is fixed at the bottom of the slider 25. The output end of the second deflection motor 24 is fixed to one end of the first support arm 21. A first deflection motor 23 is fixed to the other end of the first support arm 21. The output end of the first deflection motor 23 is fixed to one end of the second support arm 22.

[0025] As described above, the upper limb flexion adapter 2 slides under the treatment bed 1 through the cooperation of the slider 25 and the slide groove 11. At the same time, the first support arm 21 and the second support arm 22 can be deflected in the horizontal direction based on the treatment bed 1 by the second deflection motor 24. Combined with the overall sliding of the upper limb flexion adapter 2 and the vertical angle deflection between the first support arm 21 and the second support arm 22 controlled by the first deflection motor 23, the first support arm 21 and the second support arm 22 can be deflected at a large range of angles at the head of the treatment bed 1 to adapt to the arm position of different patients during treatment. The arm rests 32 and elastic support cloths 33 installed on the first support arm 21 and the second support arm 22 provide support, ensuring the upper limb comfort of the patient during treatment.

[0026] Please refer to the following: Figure 3 and Figure 4 As shown, a ball shaft 35 is fixed to the top of the sliding collar 31, and a bushing 34 is fixed to the bottom of the arm support 32. The ball shaft 35 is located inside the bushing 34, and the bushing 34 is rotatably connected to the ball shaft 35. A threaded knob 37 is threadedly connected to the bottom of the sliding collar 31, and a locking plate 36 is rotatably installed on the top of the threaded knob 37. The locking plate 36 is located at the bottom of the inner side of the sliding collar 31.

[0027] In the above description, the connection between the sliding collar 31 and the arm support 32 is made possible by a bushing 34 and a ball bearing 35. The bushing 34 can deflect at any angle above the ball bearing 35. This allows for slight adjustment of the angle of the arm support 32 after the positions and angles of the first support arm 21 and the second support arm 22 are fixed, thus accommodating slight movements of the patient's upper limb and achieving optimal support. Simultaneously, the sliding collar 31 is fitted on the outside of the first support arm 21 and the second support arm 22, allowing it to slide on the outside of these arms, thereby adjusting the arm support 32. The position of the 2nd support arm allows it to adapt to the upper limb size of different people. Since the first support arm 21 and the second support arm 22 are cylindrical, the sliding collar 31 can also rotate on the outside of the first support arm 21 and the second support arm 22, thereby changing the installation angle of the arm support 32. When used together with the first support arm 21 and the second support arm 22, which can change the deflection angle, it can provide all-round support for the patient's upper limb at the head of the treatment bed 1. The sliding collar 31 can be fixed by rotating the threaded knob 37 to push the clamping plate 36 to press against the outside of the first support arm 21 and the second support arm 22.

[0028] Furthermore, limit rings 26 are fixed to the outer sides of both ends of the first support arm 21 and the second support arm 22. The limit rings 26 can restrict the sliding path of the sliding collar 31, ensuring that the arm support 32 always slides within the set range and will not detach from the first support arm 21 and the second support arm 22.

[0029] The working principle of this utility model is as follows: Through the cooperation of slider 25 and slide groove 11, two upper limb bending adaptation brackets 2 are slid horizontally along the head end of the treatment bed to the patient's forearm area and match the patient's shoulder width. Then, the second deflection motor 24 drives the first support arm 21 to deflect horizontally, and the first deflection motor 23 drives the second support arm 22 to deflect vertically, changing the horizontal deflection angle of the first support arm 21 and the vertical bending angle between the first support arm 21 and the second support arm 22 to match the extension angle of the patient's shoulder and the bending angle of the patient's elbow. At the same time, the sliding collar 31 drives the two arm supports 32 to move to different positions of the first support arm 21 and the second support arm 22. Simultaneously, the sliding collar 31 is rotated to drive the arm supports 32 to deflect at an angle, thereby achieving the optimal position and angle for supporting the patient's forearm and forearm. After adjustment, the sliding collar 31 is fixed by rotating the threaded knob 37. During the support process, the arm supports 32 can also generate a small amplitude full-angle rotation between the bushing 34 and the ball shaft 35 to adapt to the fine adjustment after the patient's arm is extended.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
