Description

Technical Field

[0001] The present application relates to the field of medical supplies, and in particular to a radiotherapy body surface marking film. Background Art

[0002] To ensure that the radiotherapy process for cancer patients proceeds smoothly, it is necessary to draw a cross mark on the skin of the radiation area with skin ink after positioning as a reference point for radiotherapy irradiation, namely the radiotherapy positioning skin mark.

[0003] Due to many factors such as bathing, wiping, and clothes rubbing against the patient's body, the radiotherapy marking lines on the patient's body surface are often blurred or even completely lost. Inaccurate and unclear radiotherapy markings will directly affect the treatment effect of tumor patients.

[0004] At the same time, some patients are allergic to skin ink, and the radiotherapy time is long, the skin ink is easy to fall off or even disappear, so that the radiotherapy is interrupted. For this reason, during radiotherapy, the marking line needs to be redrawn every few days. After repeated drawing, the marking line will become thicker and even deviate from the original positioning point, affecting the accuracy of radiotherapy.

[0005] With regard to the above-mentioned related technologies, the inventors believe that currently before radiotherapy, a cross mark needs to be drawn on the skin of the irradiated area with skin ink after positioning as a reference point for radiotherapy irradiation, namely, radiotherapy positioning skin marking. Drawing skin ink on the body surface increases the risk of skin allergies in patients, has cumbersome steps, complicated operations, and increases positioning errors. Utility Model Content

[0006] In order to reduce the possibility of skin allergy to ink, optimize the doctor's operating steps, simplify the radiotherapy positioning process, and reduce positioning errors, the present application provides a radiotherapy body surface marking film.

[0007] The present application provides a radiotherapy body surface marking film, which adopts the following technical solution:

[0008] A radiotherapy body surface marking film comprises a covering adhesive layer, one side of the covering adhesive layer is fixedly connected to a body surface marking layer, and a marking line is arranged on the body surface marking layer.

[0009] By adopting the above technical solution, the marking line is set on the body surface marking layer, and the body surface marking layer is fixed on the covering adhesive layer, and then the covering adhesive layer adheres and fixes the body surface marking layer to the patient's skin surface. Under the prompt of the laser light positioning line, the marking line on the body surface marking layer is relatively overlapped with the laser light positioning line, which facilitates the positioning of the body surface marking layer, reduces the possibility of skin allergy to ink, optimizes the doctor's operating steps, simplifies the radiotherapy positioning process, and reduces positioning errors.

[0010] Optionally, a sweat-absorbent and breathable layer is provided between the coating adhesive layer and the body surface marking layer, and the sweat-absorbent and breathable layer is fixedly connected to the coating adhesive layer.

[0011] By adopting the above technical solution, a sweat-absorbent and breathable layer is provided between the covering adhesive layer and the body surface marking layer, so that the sweat-absorbent and breathable layer can ventilate and absorb sweat at the patient's pasting position, thereby improving the physical feeling when the film is pasted on the patient's skin.

[0012] Optionally, the sweat-absorbent breathable layer is made of a polysilane film.

[0013] By adopting the above technical solution, the polysilane film has excellent properties such as hydrophobicity, low dielectricity, chemical stability and biocompatibility, so that the sweat-absorbent and breathable layer between the covering adhesive layer and the body surface marking layer plays a role in sweat-absorbent and breathable.

[0014] Optionally, a toughness layer is provided between the covering adhesive layer and the body surface marking layer, and the toughness layer is fixedly connected to the body surface marking layer.

[0015] By adopting the above technical solution, by setting a toughness layer between the coating adhesive layer and the body surface marking layer, the toughness of the entire film can be improved, so that the overall tensile effect of the film is better, the use time of the film is extended, and the damage caused during use and the occurrence of inaccurate positioning can be reduced.

[0016] Optionally, the tough layer is made of thermoplastic polyurethane elastomer rubber.

[0017] By adopting the above technical scheme, the thermoplastic polyurethane elastomer rubber has the characteristics of excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance, which plays a role in ensuring the elasticity of the body film and improving the service life of the overall film.

[0018] Optionally, the tough layer is located on a side of the sweat-absorbing and breathable layer close to the body surface marking layer, and the tough layer is fixedly connected to the sweat-absorbing and breathable layer.

[0019] Optionally, the marking line includes a horizontal marking line and a vertical marking line that are relatively vertically arranged, and the intersection point of the horizontal marking line and the vertical marking line is the marking point.

[0020] By adopting the above technical solution, the marking line is formed into a marking horizontal line and a marking vertical line, so that the marking point where the marking horizontal line and the marking vertical line form the intersection is relatively overlapped with the intersection of the laser light positioning line, thereby improving the alignment accuracy.

[0021] Optionally, the marking line is a red line.

[0022] By adopting the above technical solution and setting a red marking line, the overall marking line is made more eye-catching, which makes it easier for medical staff to mark the marking line by aligning it with the laser light positioning line.

[0023] Optionally, the laminating adhesive layer, the sweat-absorbing and breathable layer, the toughness layer and the body surface marking layer form a composite film, and the thickness of the composite film is 0.5 cm.

[0024] Optionally, the composite film is a circular structure, and the marking point is located at the center of the composite film.

[0025] By adopting the above technical solution, the composite film composed of the covering adhesive layer, the sweat-absorbing and breathable layer, the toughness layer and the body surface marking layer is formed into a circular structure, which can better adapt to the patient's movements and reduce the occurrence of wrinkles or shedding on the body surface.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By forming the marking line on the body surface marking layer, and the body surface marking layer is fixed to the patient's skin surface through the coating adhesive layer, it is reduced to use skin ink to draw directly on the skin of the radiation area. Under the prompt of the laser light positioning line, the marking line on the body surface marking layer is relatively overlapped with the laser light positioning line, which facilitates the positioning of the body surface marking layer, reduces the possibility of skin allergy to ink, optimizes the doctor's operating steps, simplifies the radiotherapy positioning process, and reduces the positioning error.

[0028] 2. When the patient is positioned for radiotherapy, the body film or vacuum pad is first positioned, and then the body film or vacuum pad is pasted on the skin under the guidance of the laser light positioning line. By using the radiotherapy body surface marking film provided by this application, the patient can bathe and exercise normally during radiotherapy, which relieves the psychological pressure of the patient during radiotherapy.

[0035] To ensure that the radiotherapy process for cancer patients proceeds smoothly, it is necessary to draw a cross mark on the skin of the radiation area with skin ink after positioning as a reference point for radiotherapy irradiation, namely the radiotherapy positioning skin mark.

[0036] Due to many factors such as bathing, wiping, and clothes rubbing against the patient's body, the radiotherapy lines marked on the patient's body surface are often blurred or even completely lost.
