Description

Technical Field

[0001] The utility model relates to a safety device, in particular to an emergency evacuation and anti-dumping safety device for a breast tumor radiotherapy bed, belonging to the technical field of treatment bed protection. Background Art

[0002] The breast tumor radiotherapy system includes a treatment couch that can be switched between upright and horizontal positions; the patient wears a breast immobilization device in the upright position to complete the imaging scan. Before treatment, the patient stands on the pedal at the end of the treatment couch in an upright position and inserts the breast immobilization device into the positioning hole of the treatment couch. The treatment couch is then flipped to a horizontal position and placed above the treatment machine head. The patient needs to wear the breast immobilization device during imaging scans and treatment, and needs to perform imaging scans and treatment in a prone position to obtain better images and more accurate radiotherapy. The patient is in an upright position before treatment. In order to prevent the breast immobilization device from failing and causing breast displacement, the patient stands on the treatment couch in an upright position, and the treatment couch is flipped to switch the patient to a prone position. The anti-tilt device of the treatment couch is a protective device that is used when the equipment fails to work properly during treatment and the treatment couch cannot be flipped, requiring medical staff to assist the patient in evacuating the treatment couch.

[0003] Currently, the treatment bed is in a horizontal position on the treatment device. If the medical staff or patient mistakenly operates the handle to jam the head of the treatment bed, the treatment bed will be stuck when the treatment bed is turned over according to the normal treatment procedure, resulting in the treatment bed being unable to be turned over as expected, and there is also the possibility of damage to the treatment equipment. When the treatment bed is in an upright position, if the medical staff or patient mistakenly operates the handle to extend the safety device, the treatment bed cannot be placed on the treatment device when the treatment bed is turned over according to the normal treatment procedure, which will also affect the patient's treatment. Utility Model Content

[0004] The purpose of the present utility model is to provide an emergency evacuation anti-tip safety device for a breast tumor radiotherapy couch in order to solve the above-mentioned problem. The device can prevent the couch from getting stuck and affecting its flipping due to misoperation. At the same time, the couch can be smoothly flipped onto the treatment device without being blocked, ensuring smooth treatment and preventing safety accidents caused by misoperation of the device.

[0005] The utility model achieves the above-mentioned object through the following technical solutions: a breast tumor radiotherapy bed emergency evacuation anti-dumping safety device includes a fixed block, the fixed block is provided with a protective mechanism, the protective mechanism includes a sliding member, a sliding member slides on the fixed block, the sliding member is provided with a limiting groove, the internal sliding connection of the sliding member is connected to the limiting member, the limiting member is fixedly connected to a fixing member that slides with the fixed block, an elastic member is clamped between the limiting member and the sliding member, and the limiting member is provided with a breaking groove.

[0006] Preferably, the limiting member is a plastic block with an inclined end portion.

[0007] Preferably, a pushing mechanism is installed on the fixed block, and the pushing mechanism includes a movable groove and a sliding rod. The fixed block is provided with a movable groove, and a sliding rod fixed to the fixed block is provided at the movable groove. A movable block slides on the sliding rod, and a limit pin is provided on the movable block, and the limit pin is inserted into the interior of the limit groove.

[0008] Preferably, there are two sliding rods, and the two sliding rods are cylindrical structures.

[0009] Preferably, the cross section of the disconnecting groove is a triangular structure, and the disconnecting groove is located at the bottom of the limiting member.

[0010] Preferably, the cross section of the sliding member is L-shaped, and the moving groove on the sliding member is located at the bottom of the moving block.

[0011] Preferably, a driving mechanism is installed on the fixed block, and the driving mechanism includes a fixed seat and a movable slot. A fixed seat is fixedly connected to the outside of the fixed block, a driving plate is rotatably connected to the fixed seat, a push rod is rotatably connected to the driving plate, the push rod is rotatably connected to the moving block, a movable slot is provided on the fixed block, a connecting rod located at the movable slot is rotatably connected to the fixed block, and the connecting rod is rotatably connected to the driving plate.

[0012] Preferably, the driving mechanism further includes a handle, and the driving plate is fixedly connected to the handle.

[0013] The beneficial effects of the present invention are as follows: when the driving mechanism is turned, the pushing mechanism is driven to move. Since the limiting groove on the sliding member is arranged obliquely and becomes lower from left to right, when the pushing mechanism moves to the right, the limiting pin cooperates with the limiting groove to drive the sliding member to extend outward from the fixed block, thereby limiting the position of the treatment bed and preventing the treatment bed from tipping over. When the treatment bed is flipped toward the treatment device by the flipping mechanism, the inclined portion of the limiting member can be pressed and retracted into the inside of the fixed limiting member, without affecting the placement of the treatment bed. If the driving mechanism is misoperated and causes the limiting member to extend and block the treatment bed, the limiting member will be disconnected from the disconnection groove when the flipping mechanism flips the treatment bed, thereby avoiding safety accidents.

[0023] As a technical optimization solution of the present utility model, the pushing mechanism 3 includes a movable groove 301 and a slide rod 302. The fixed block 1 is provided with a movable groove 301, and the movable groove 301 is provided with a slide rod 302 fixed to the fixed block 1. A movable block 303 slides on the slide rod 302, and a limit pin 304 is provided on the movable block 303. The limit pin 304 is inserted into the inside of the limit groove 402. When the movable block 303 is driven by the driving mechanism 2 to a point outside the fixed block 1, the movable block 303 extends out of the outside of the fixed block 1, thereby limiting the treatment bed and preventing it from flipping.

[0024] As a technical optimization solution of the present invention, two slide rods 302 are provided, and the two slide rods 302 are cylindrical structures, which enables the moving block 303 to move on the slide rods 302 and ensures the stability of the moving block 303 when moving.

[0025] As a technical optimization solution of the present invention, the cross-section of the disconnection groove 406 is a triangular structure, and the disconnection groove 406 is located at the bottom of the limiter 403. When the driving mechanism 2 is misoperated and causes the limiter 403 to extend and block the treatment bed, the limiter 403 will disconnect from the disconnection groove 406 when the flip mechanism flips the treatment bed, thereby avoiding safety accidents.

[0026] As a technical optimization solution of the present invention, the cross section of the sliding member 401 is L-shaped, and the moving groove 301 on the sliding member 401 is located at the bottom of the moving block 303 .

[0027] As a technical optimization solution of the present utility model, the driving mechanism 2 includes a fixed seat 201 and a movable groove 202. The fixed seat 201 is fixedly connected to the outside of the fixed block 1. The fixed seat 201 is rotatably connected to the driving plate 205. The driving plate 205 is rotatably connected to the push rod 204. The push rod 204 is rotatably connected to the moving block 303. The fixed block 1 is provided with a movable groove 202. The fixed block 1 is rotatably connected to a connecting rod 203 located at the movable groove 202. The connecting rod 203 is rotatably connected to the driving plate 205.

[0028] As a technical optimization solution of the present invention, the driving mechanism 2 further includes a handle 206 , and the handle 206 is fixedly connected to the driving plate 205 .

[0029] When the present invention is used, the patient wears the breast fixation device and stands on the pedal of the treatment bed. The treatment bed is flipped over by the flip mechanism and is close to the treatment bed. At this time, the patient is in a prone position to receive treatment. When the treatment bed is close to the treatment device, the limiting member 403 can be squeezed into the interior of the sliding member 401. Since the end of the limiting member 403 is inclined, as the treatment bed descends, the limiting member 403 continues to move into the interior of the sliding member 401, and the elastic member 405 (preferably a spring) is squeezed and contracted, and the sliding member 401 also contracts a certain distance. When the treatment bed is completely fitted with the treatment device, the elastic member 405 pops out the limiter 403. The extended portion of the limiter 403 is an inclined surface. Even if the limiter 403 is in the extended state, when the treatment bed is flipped to the horizontal position, the limiter 403 will be pushed into the fixed block 1 to avoid safety accidents. The limiter 403 is made of a material with lower strength such as ABS, and has a disconnection groove 406 at the bottom. When the handle 206 is misoperated and causes the limiter 403 to extend and block the treatment bed, the limiter 403 will be disconnected from the disconnection groove 406 when the flip mechanism flips the treatment bed, thereby avoiding To avoid safety accidents, since the limiter 403 is located at the front end of the bed, only a small force is needed to prevent the bed from tipping over during emergency evacuation of the patient. When the limiter 403 accidentally extends out to block the flipping of the treatment bed due to misoperation, the force of the flipping mechanism is sufficient to break the limiter 403. The design of the disconnection groove 406 ensures that the patient weighing less than 150 kg will not break when evacuating from the rear end of the treatment bed. However, the mechanism for flipping the treatment bed (such as the bedside steel pipe of the treatment bed) is sufficient to break the disconnection groove. The treatment bed needs to be fixed during treatment. At this time, the handle 206 can be turned to the right. The driving plate 205 is driven to rotate, causing the connecting rod 203 to rotate clockwise, thereby pulling the push rod 204 to move to the right. After the push rod 204 moves to the right, the moving block 303 moves to the right on the slide rod 302. After the moving block 303 moves, it drives the limit pin 304 to move. Since the limit slot 402 on the sliding member 401 is set at an angle and becomes lower and lower from left to right, when the moving block 303 moves to the right, the limit pin 304 cooperates with the limit slot 402 to drive the sliding member 401 to extend out of the outside of the fixed block 1, thereby limiting the treatment bed and preventing the treatment bed from tipping over.
