[0022] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0023] like Figures 1 to 4 As shown, in order to solve the problem of particles being unable to be fixed and easily falling off during the treatment of basal cell carcinoma, and being unable to control the radiation dose and solve the problem of radiation protection, the utility model provides a basal cell carcinoma radiation portable particle patch, including a particle bin layer 3, a lead sheet protective layer 1, a skin-like coating 6, a double-sided adhesive layer 2, a silicone gel layer 4 and other structures, with rectangular, square or circular shapes. The following is a detailed introduction using a rectangular structure as an example. The four corners of the rectangular portable particle patch are rounded to prevent the sharp corners of the lead sheet from causing scratches, punctures and other injuries to the skin, and also to make the portable particle patch more beautiful.
[0024] The particle bin layer 3 of the portable particle patch is a compressed cotton sheet with a thickness comparable to the particle diameter. The compressed cotton sheet is breathable, water-permeable, and absorbent, which can prevent patients from skin ulcers caused by long-term application. An array of particle bins 5 with a spacing of 5mm and a row spacing of 6.8mm is arranged in the center of the compressed cotton sheet, with a total of 21 particle bins 5. The particle bin 5 is a rectangular through groove with a length of 4.2mm and a width of 0.5mm. The particles are cylinders with a diameter of 0.8mm and a height of 4.5mm. The volume of the particle bin 5 is smaller than the volume of the particles to better fix the particles so that the particles will not move or shake in the particle bin 5. A blank edge slightly larger than the width of the particle radiation radius is left around the particle bin 5 array to avoid particle radiation spillage during the use of this portable particle patch. The particle bin 5 array can adjust the radiation dose according to the patient's condition, thereby increasing or decreasing the number of iodine-125 radioactive particles. The control of iodine-125 radioactive particles can be precisely adjusted, and the operation is more convenient and quick.
[0025] One side of the particle storage layer 3 has a medical double-sided adhesive layer 2. This layer 2 adheres to one side of the particle storage layer 3, forming a spatial groove with the other. The double-sided adhesive layer 2 secures the radioactive particles at the bottom of the groove, preventing them from moving. The other side of the double-sided adhesive layer 2 adheres to the lead sheet protective layer 1, providing a bond between the lead sheet protective layer 1 and the particle storage layer 3.
[0026] The lead sheet protective layer 1 is a lead sheet with a thickness of 0.25-0.5mm. The specific thickness can be determined according to the radiation dose required for treatment, so that the lead sheet protective layer 1 can completely block the overflow of particle radiation. Due to the characteristics of lead, it can isolate particle radiation very well and protect the radiation damage to patients or others caused by radiation in non-treatment areas. The lead sheet is very soft and can easily deform with the unevenness of the skin to fit closely to the skin. The outside of the lead sheet protective layer 1 is covered with a skin-like coating 6, which is both beautiful and practical and avoids the harm of exposed lead sheet to the human body. The lead sheet protective layer 1, the particle bin layer 3 and the skin-like coating 6 are consistent in size, which is beneficial to the discharge of water vapor on the skin surface and avoids skin ulcers caused by long-term application.
[0027] The double-sided adhesive layer 2 on the other side of the particle bin layer 3 is a medical breathable film. The edge of the medical breathable film is bonded to the edge of the particle array of the particle bin layer 3, with a bonding width of 5-15mm. The unbonded area is separated by a release paper 7. This makes it convenient for doctors to open the particle bin 5 and load the required number of iodine-125 radioactive particles according to the radiation dose required for the condition. After the particles are loaded, the release paper 7 is torn off and the medical breathable film is bonded to the particle bin layer 3 to form a closed space in the particle bin 5, where the particles are sealed and stored. In this way, the particles are fully fixed in the groove and will not shake or shift in space. The other side of the double-sided adhesive layer 2 is bonded with a silicone gel layer 4. The silicone gel layer 4 is a medical patch with strong adhesive properties that can ensure repeated use. The silicone gel layer 4 is not afraid of sweating and water on the patient's skin and has good water and adhesive properties. This ensures that the patient can re-attach the patch after removing the portable particle patch and can repeat the operation many times. The surface of the silicone gel layer 4 is covered with a release paper 7. When in use, the release paper 7 can be peeled off to apply the patch, which is convenient and practical. There are two types of silicone gel layers 4. One is a complete bonding surface, so that the entire patch can be adhered to the skin surface; the other is hollowed out in the middle of the patch, and only silicone gel is present around the portable particle patch to adhere to the skin surface. This design is based on the consideration that when the patient's skin surface is intact, the first type of patch can be applied; when the patient's skin is ulcerated, the second type of silicone gel layer 4 can be used, which is convenient for the doctor to disinfect and treat the patient's ulcerated skin surface. The treatment will not be interrupted because the patient uses the portable particle patch for radiation treatment, and it is conducive to continuous radiation treatment of the affected area, achieving better treatment results and allowing patients to have a better treatment experience.
[0028] The present invention also has a second set of solutions, which is an improvement on the first set of solutions. The second set of solutions has the same structure as the particle bin layer 3, double-sided adhesive layer 2, lead sheet protective layer 1, and skin-like coating 6. Only on the side of the particle bin layer 3 that contacts the skin, a layer of medical breathable film has been streamlined and removed, leaving only a layer of medical silicone gel layer 4 that contacts the skin. One side of this silicone gel layer 4 is bonded to the particle bin layer 3 by 5-15mm, and the remaining unbonded part is separated by release paper 7 to facilitate the doctor to open the particle bin 5 and load the required radioactive particles. After placing the required particles, the release paper 7 is torn off, and the silicone gel layer 4 is fully bonded to the particle bin 5 to complete the loading of the radioactive particles. The other side of the silicone gel layer 4 is covered with release paper 7. After peeling off this layer of release paper 7, the portable particle patch can be applied to the skin surface of the affected area for treatment.
[0029] The method of using the portable particle patch of the utility model is as follows:
[0030] 1. Take out the basal cell carcinoma radiation-carrying particle patch, open the particle layer and the dressing layer to expose the particle compartment 5, load the required particles, press the particles tightly so that they fit on the bottom adhesive layer, tear off the release paper 7, and fully bond the dressing and the particle patch together to form a complete patch.
[0031] 2. Choose different types of portable particle patches based on the temperature, humidity, and health of the patient's skin. If the temperature is very high and the humidity is high, you can choose the second set of patches to keep the patient's skin dry and breathable, and long-term application will not cause skin ulcers. If the temperature is low, the air is dry, and the patient's skin is intact, you can choose the first set of patches for lamination; if the patient's skin is already ulcerated, you can choose a silicone gel layer 4 with a hollowed-out center and laminated around the edges. This will not delay the anti-inflammatory and antibacterial treatment of the patient's ulcerated skin, and can also provide uninterrupted radiation therapy to the patient's affected area.
[0032] 3. Peel off the bottom layer of release paper 7, and align the particles with the cancerous spots on the patient's skin according to the position of the particles in the particle chamber 5, and then stick them.
[0033] 4. The silicone gel layer 4 has good adhesion properties after multiple laminations. The patient can remove the portable particle patch by himself during bathing or cleaning and operate it. After completion, the patient can also apply it on the skin surface by himself, which brings great convenience to the patient's life and effectively saves valuable doctor resources.
[0034] 5. When the patient removes the dressing to perform other operations, the dressing can be placed in a lead box to avoid radiation damage to the patient or family members.
[0035] The beneficial effects of the utility model are:
[0036] 1. Combining particles with dressings is a novel innovation that is convenient and practical. It can accurately grasp the radiation dose and control the duration of radiation. It is also more convenient to operate and more flexible.
[0037] 2. The cotton pad in particle chamber 5 is made of compressed cotton. Its breathable, water-permeable and water-absorbing properties have a good protective effect on the patient's skin when applied for a long time, making it less likely for the patient's skin surface to ulcerate.
[0038] 3. There are double-sided tapes on the top and bottom of the cotton pad of particle bin 5, which can be combined with the groove of particle bin 5 and the double-sided tape to form a closed space, which has a good fixing effect on the particles and prevents the particles from shaking and displacement.
[0039] 4. The particle chambers are arranged in an array of 5 to make the particle radiation more uniform and the radiation treatment of the patient's area more accurate and efficient.
[0040] 5. There are blank spaces around the particle chamber 5 array, which can effectively prevent the spillover of particle radiation and provide beneficial radiation protection for patients and others.
[0041] 6. The full coverage of the lead sheet can provide a good radiation isolation for particle radiation, avoiding unnecessary radiation damage caused by particle radiation.
[0042] 7. The skin color protective film of the lead sheet is both beautiful and avoids the harm of lead pollution to the human body.
[0043] 8. The silicone gel layer 4 can ensure that it remains sticky even when the skin sweats or comes into contact with water, maintains a good fit with the skin, and can be reused many times.
[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
