Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable breast bracket for radiotherapy. Background Art

[0002] Radiation therapy is a treatment method that uses high-energy radiation, such as X-rays or other forms of ionizing radiation, to kill cancer cells or stop them from growing and dividing. In the breast cancer treatment room, the patient lies on the treatment bed and raises or moves their hands outward to avoid compressing the breast.

[0003] Publication number CN212651240U retrieved discloses a breast support for radiotherapy, which relates to the field of medical device technology. By relatively fixing the patient's hands, the distortion of the body is reduced, and the displacement of the irradiated part is avoided, thereby achieving precise treatment of the affected part and reducing damage to normal parts. The specific scheme is: comprising a horizontal bed, the horizontal bed is provided with a head groove and two chest grooves, and the horizontal bed is provided with two hand positioning rods at one end close to the head groove. The hand positioning rods are closer to the end of the horizontal bed relative to the head groove. The horizontal bed is provided with a sliding track for the movement of the hand positioning rods, and the two hand positioning rods move synchronously in the same direction relative to the center point of the sliding track. The breast support for radiotherapy provided by the utility model effectively prevents the patient from twisting the body due to the asynchronous swinging of the hands by synchronously driving the arms to move, thereby improving the treatment effect. The breast support for radiotherapy can be used for patients of different body shapes and has a wider range of applications.

[0004] This patented technology has significant advantages when used. However, when the patient lies flat on his back with his hands raised backward, there is a gap between his arms and the bed. The arms hanging in the air will cause soreness, numbness and fatigue, which will make him uncomfortable during the treatment. Therefore, we propose an adjustable breast support for radiotherapy to solve the existing problem. Utility Model Content

[0005] The purpose of the utility model is to address the problems existing in the background technology and to provide an adjustable breast bracket for radiotherapy.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adjustable breast bracket for radiotherapy, comprising a support plate and a bracket structure, wherein a screw hole is provided inside the support plate, and symmetrically distributed bracket structures are provided on both sides of the upper end of the support plate, and the bracket structure comprises a mounting tube, an adjusting rod slidably inserted into the mounting tube, and a bracket sleeve located at the upper end of the adjusting rod, a screw is provided at the upper end of the mounting tube, a support ring is provided at the opening of the mounting tube, a spring is provided at the lower end of the support ring that is sleeved on the outside of the adjusting rod, a piston is provided at the lower end of the adjusting rod that is slidably inserted into the mounting tube, a rotating seat is provided at the upper end of the adjusting rod, a universal ball is provided at the lower end of the bracket sleeve, a rubber ball is provided on one side of the mounting tube, an air intake valve is provided at one end of the rubber ball, and an exhaust valve is provided at one end of the rubber ball.

The support ring and the fixing ring support the upper and lower ends of the spring, and the fixing ring moves with the adjusting rod, so that the elastic supporting force of the spring acts on the adjusting rod.

[0010] Preferably, the lower end of the universal ball is rotatably mounted inside the rotating seat, and a damping sleeve is provided between the universal ball and the rotating seat. The damping sleeve applies resistance to the universal ball when the universal ball rotates inside the rotating seat, and although the rotation is difficult, a good stability effect is maintained after the rotation.

[0011] Preferably, a latex pad is provided on the inner wall of the upper end of the bracket sleeve, which provides a soft and elastic support condition for the hand when placed, thereby improving the comfort of the hand when placed.

[0012] Preferably, one end of the rubber ball is penetrated by a delivery pipe, and one end of the delivery pipe is penetrated by the interior of the lower end of the mounting tube. Gas sucked by the rubber ball through the air inlet valve enters the interior of the delivery pipe through the delivery pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The support plate of the utility model supports the bracket structure, and the bracket sleeve is adjusted in angle inside the rotating seat through the universal ball. The inside of the mounting cylinder is pressurized by pressing the rubber ball, and the piston is pushed upward by the pressure. The spring is forced to contract and the height of the adjusting rod is adjusted. When the patient lies flat on the bed, the suspended arm is supported by the bracket sleeve, and the hand is more comfortable during radiotherapy for breast cancer. The bracket sleeve can be adjusted in angle and height. During use, the bracket sleeve can be adjusted according to the patient's physical condition, and it is flexible to use.
