Description

Technical Field

[0001] The invention relates to the field of packaging film pressing and recovery devices, in particular to a packaging film pressing and recovery device for a nuclide therapy applicator. Background Art

[0002] Radionuclide patch therapy is a common method for treating skin keloids. Commonly used radionuclide drugs are aqueous solutions of radionuclides such as phosphorus-32. These radionuclides release beta rays during the decay process, which act on fibroblasts in scar tissue, causing them to degenerate, destroy the original scar tissue, and gradually flatten the scar to achieve the purpose of treatment. Since beta rays can irradiate skin lesions with a depth of 3-4 mm, most of the energy is absorbed by the shallow lesions without causing damage to the deep tissue. It is a treatment method for skin keloids with a definite effect, safety, painlessness, and low recurrence. However, since these radionuclides are radioactive, they cannot be applied directly to the body surface, otherwise it will cause radioactive leakage and contamination, further leading to the loss of control of the radiation exposure range, causing normal tissues to be exposed to unnecessary radiation, resulting in treatment failure or causing a series of adverse reactions. Therefore, these radionuclide drugs must be sealed in a certain way to make a radionuclide applicator. The radionuclide applicator is then placed on the surface of the keloid before the tissue in the lesion area can be subjected to close-range radiotherapy.

[0003] The existing applicator is made by hand from a paper core and a plastic film wrapped around it. The production steps are: 1. First, cut the paper core according to the shape of the lesion area; 2. Then, use the water absorption of the paper core to drip the radioactive nuclide drug on the paper core; 3. Then dry the paper core; 4. Finally, use a plastic film to seal the paper core between two layers of plastic film. After the applicator is made, it is pasted on the skin lesion with medical tape, and the whole treatment process is completed. The patient can leave the hospital with the pasted applicator. Commonly used plastic films include thermoplastic film, PU film, etc. After the applicator is pasted on the skin lesion for a certain period of time, the patient removes the applicator by himself. At this time, the applicator is still radioactive, so it cannot be discarded at will, and must be stored in an appropriate container. When the follow-up visit is made, the applicator and the container will be returned to the hospital together and stored in a designated area by the hospital. After being stored for more than 10 half-lives of phosphorus-32, it can be treated as ordinary medical waste.

[0004] Existing applicator packages have the following disadvantages: 1. The packaging process is manual operation, and there is a possibility of loose packaging, which may cause leakage of radionuclide drugs; 2. The distance between the hand and the applicator is relatively close during operation, and the operator is exposed to a large radiation dose; 3. It takes a long time and the packaging efficiency is low.

[0005] At the same time, after the treatment, a container for the applicator needs to be prepared separately, which increases the workload of hospitals and doctors. The protective performance of such self-prepared containers varies, and there is a possibility of poor radiation protection and loss.

[0006] In order to solve the above problems, the present application proposes a radionuclide therapy applicator packaging film recovery device Summary of the invention
