Description

A transfer bed for brachytherapy positioning treatment of gynecological tumors

technical field

The invention relates to the technical field of medical devices, in particular to a transfer bed for brachytherapy positioning treatment of gynecological tumors.

Background technique

Gynecological tumor brachytherapy includes radiotherapy for cervical cancer. Cervical cancer is a common tumor in gynecology. Backloading therapy is one of the important methods for the treatment of cervical cancer. Gynecological afterloading therapy is to put the applicator without radioactive source into the vagina and uterine cavity, start the afterloading machine in a well-protected control room far away from the treatment room, and send the radioactive source into the container for treatment. Return the source to the source tank. The patient needs to take the lithotomy position on the gynecological examination bed. The medical staff will put the selected applicator into the patient's treatment site and fix it. The area to be aligned will be aligned through irradiation positioning. The aligned area will be displayed on the on the image processor, and then use the afterloading therapy device for treatment. During this process, the patient must remain in position and cannot move, and the applicator must be kept still;

Brachytherapy for gynecological tumors (such as putting the source applicator without radioactive source into the vagina and uterine cavity, in a well-protected control room far away from the treatment room, start the post-installation machine, send the radioactive source into the container for treatment, and the treatment is completed Putting the radioactive source back into the storage tank at the time) is one of the important methods for the treatment of cervical cancer at present. During the treatment process, the patient must keep the body position and the applicator must be kept still. Therefore, in order to facilitate the transfer of the patient, a transfer bed for the transfer of the patient is designed, which is very convenient and practical, and not only reduces the labor intensity of the staff. , and further prevent the patient from causing secondary injury during the transfer process.

The working principle and beneficial effects of the above technical solution are: when the transfer bed needs to be moved, the T-shaped block 12 will slide up and down on the inner wall of the shock absorbing box 11 when the road surface is uneven, and Shock absorbing spring one 141 squeezes, and the shock absorbing spring two 142 compresses accordingly, further making the slide bar 4 slide inside the rectangular plate 5, thereby shock-absorbing the transfer bed;

By setting up a shock absorbing mechanism, it is possible to prevent the transfer bed from bumping and causing harm to the patient due to the uneven road surface during the transfer process, and by setting and installing shock absorbing spring 1 141 and shock absorbing spring 2 142, the shock absorbing effect is improved , to further reduce the harm of vibration to the patient, and solve the technical problem that the existing transfer bed is easy to cause bumps during the transfer process when the patient is in operation.

Example 2

On the basis of Embodiment 1, the front and rear ends of the fixed plate 6 are provided with a number of limit rods 7, and the fixed plate 6 is provided with a number of concave grooves 8; The top end is fixedly installed on the bed board 10 , and the slider one 9 is slidably connected to the concave groove 8 .

The working principle and beneficial effects of the above-mentioned technical solution are as follows: when the medical personnel need to transfer the patient to another transfer bed, the medical personnel first set the limit rod 7 on the transfer bed where the patient is located to the limit position corresponding to the other transfer bed. slots, and then the bed board 10 on the transfer bed where the patient is located is docked with the concave groove 8 on another transfer bed through slider one 9, and then the medical staff pushes the bed board 10 to transfer the patient to another transfer bed. bed, so as to realize the transfer of patients, which is very convenient and practical, and at the same time reduces the secondary injury to patients.

The working principle of the above technical solution is: when the medical personnel need to fix the transfer bed, firstly, by starting the drive motor 58, the drive motor 58 drives the driving wheel 59 to rotate, and the rotation of the 59 drives the driven wheel One 551 and the second driven wheel 552 rotate, and the second driven wheel 552 rotates to drive the second fixed block 60 to rotate, so that the second fixed block 60 rotates, and contacts and fixes the place through the second opening 53; When the personnel needs to recover the fixed block 2 60, the drive motor 58 is rotated counterclockwise to recover the fixed block 2 60, and the roller 64 moves upward in the arc-shaped groove 65;

When the drive motor 58 is damaged or unable to run, the medical personnel can start the battery 2 66, and the battery 2 66 energizes the electromagnetic coil 67, and the energization of the electromagnetic coil 67 makes the iron core 68 energized and has a Magnetism, under the action of magnetism, drives the adjustment rod 70 to move to the right, thereby stretching the return spring 3 413, further making the concave iron block 71 contact with the iron core 68, and the adjustment rod 70 moves to the right The movement causes the connecting rod three 72 to rotate accordingly, so that the bottom end of the connecting rod three 72 drives the connecting rope 73 to move to the left, and then drives the mounting bar 62 to move upwards, and further makes the fixing block two 60 to be recovered upwards. When it needs to be fixed again, it is only necessary to turn off the second battery 66 so that the adjusting rod 70 will loosen the connecting rope 73 under the reset action of the return spring 3 413 , thereby fixing the fixing block 60 .

The beneficial effects of the above technical solution are: by setting the ground fixing device 51, it is beneficial for the medical staff to fix the transfer bed, prevent the transfer bed from slipping under the action of the moving wheel 2, and further reduce the secondary damage to the patient; A plurality of sets of driven wheels are set, which increases the distance of the gear transmission, makes the fixing process of the fixing block 2 60 to the ground more gentle, prevents the fixing from being carried out too fast, increases the vibration of the transfer bed, and further protects the fixing device 51; By setting the auxiliary fixing device, it is beneficial for the medical staff to fix the rotating bed when the drive motor 58 cannot be used, which is very convenient and practical. Under normal circumstances, the fixed block 2 60 is reset, which reduces the loss of electric energy, further meets the requirements of users, and increases the diversity of the transfer bed.
