Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an arm supporting device for radiotherapy. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioisotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy during the treatment of cancer, and about 40% of cancers can be cured by radiotherapy. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent, and it has become one of the main means of treating malignant tumors.

[0003] Currently, when positioning a tumor for radiotherapy, the patient needs to raise his hands above his head after lying on the radiotherapy bed to facilitate the operation of medical staff. However, since the positioning process is long, keeping the hands raised for a long time will not only cause poor blood circulation in the arms and numbness in the arms, but also cause discomfort to the patients.

[0004] In the prior art, in order to solve this problem, medical staff will add padding or clothing under the patient's arm to assist in raising the arm so that the patient's arm can get a certain support. However, this method has poor applicability, cannot be adjusted according to the patient's needs, and is inconvenient to use.

[0005] In addition, since drugs need to be injected after positioning and then scanned, and since the space of the radiotherapy bed is limited, after the patient lies on the bed, there is no suitable space to place the syringes and other instruments and drugs used to inject drugs. If they are forcibly placed on the radiotherapy bed, the radiotherapy bed will fall when it moves. Therefore, in the prior art, medical staff often let patients hold these instruments by themselves, which not only increases the burden on patients, but also has the risk of patients dropping them due to unstable hands.

[0043] There are two first limiting plates 601, which are respectively arranged on the left and right sides of the upper front end surface of the mounting seat 210 to improve the clamping stability.

[0044] The limiting block 603 is made of elastic material.

[0045] The working principle of the utility model is:

[0046] Before positioning, the medical staff can pull the storage box 401 out of the accommodating cavity 212 in the mounting seat 210 by the handle 402, put the relevant medicines and instruments into the storage box 401, release the handle, the spring 504 contracts, pull the connecting rod 503 and the connecting plate 501, and then pull the storage box 401 back into the accommodating cavity 212. When taking out the medicine, just take it out in the above method.

[0047] When positioning, the patient lies on the bed 1, and the medical staff shakes the hand wheel 211 to drive the screw 203 to rotate, so that the first slider 204 and the second slider 205 move toward each other, so that the first connecting rod 208 and the second connecting rod 209 drive the mounting seat 210 to rise to a suitable position. The patient is asked to raise both hands above the head and place them on the support pillow 301. The medical staff then adjusts the height to a comfortable height for the patient according to the patient's needs, and then the positioning work can be carried out.

[0048] When the support pillow 301 needs to be removed, the storage box 401 can be pulled out of the accommodating cavity 212 in the mounting seat 210 by the handle 402, so that the second limit block 603 no longer contacts the support pillow 301. At this time, the support pillow 301 is removed, the hand is released, the spring 504 contracts, and the connecting rod 503 and the connecting plate 501 are pulled to pull the storage box 401 back into the accommodating cavity 212. When the support pillow 301 needs to be installed, the storage box 401 can be pulled out of the accommodating cavity 212 in the mounting seat 210 by the handle 402, the support pillow 301 is placed on the mounting seat 210, the hand is released, the spring 504 contracts, the connecting rod 503 and the connecting plate 501 are pulled, and the storage box 401 is pulled back into the accommodating cavity 212, so that the limit block 603 contacts the support pillow 301, and the support pillow 301 is pressed tightly in cooperation with the first limit plate 601.
