Description

Technical Field

[0001] The utility model relates to the technical field of nuclear magnetic positioning tapes, in particular to a special gel tape for radiotherapy nuclear magnetic simulation positioning. Background Art

[0002] In radiotherapy, MRI simulation positioning requires positioning markers to determine the patient's treatment target area, which can then be integrated with the CT simulation positioning image to accurately determine the tumor target area. Currently, the marking materials used for MRI simulation positioning are vitamin pills. In actual operation, due to the large size of vitamin pills, when the scanning layer thickness is thin, the error in the isocenter marking is large. At the same time, when affixing positioning markers, ordinary medical tape is usually used to fix them. In actual operation, the radiotherapy technician uses scissors to tear out the medical tape and stick the vitamin pill to the skin surface. Different patients can reuse the same vitamin pill, which cannot ensure sterility and easily causes cross-infection between patients.

[0003] Therefore, there are many types of tapes used for radiotherapy, and cross positioning marks are set on the tapes to achieve positioning marking. For example, China's authorized patent (authorization announcement number: CN211705029U) discloses a medical tape specifically for radiotherapy. By setting printed cross positioning marks on the surface of the tape body, it is convenient for medical equipment to locate the area that needs treatment when the tape is attached to the patient. By setting easy-to-tear lines at equal intervals on the tape body, medical personnel can easily tear the tape body without the help of tools.

[0004] When medical staff need to use it, they need to lift one end of the tape with their fingers, tweezers or scissors, and then pinch the tape to tear it from the tearing point. It is easy for impurities to adhere to the lifted part, and wrinkles are easy to appear at the lifted part. Utility Model Content

[0005] The purpose of the utility model is to provide a special gel tape for radiotherapy nuclear magnetic simulation positioning to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A special gel tape for radiotherapy nuclear magnetic simulation positioning, comprising a winding tube and a release paper wrapped around the winding tube;

[0008] A plurality of equally spaced adhesive pieces are pasted on the release paper, each adhesive piece is provided with a silicone ball and a cross mark line, and the silicone ball is located at the intersection of the cross mark line;

[0009] A tearing portion is formed between two adjacent adhesive pieces;

[0010] A pinching portion is formed at a top corner of the adhesive piece, and the pinching portions of two adjacent adhesive pieces are staggeredly distributed along both sides of the length direction of the release paper.

[0011] The gel tape specially used for radiotherapy MRI simulation positioning as described above: a gap is formed between one end surface of the tearing portion and the opposite surfaces of the two adhesive members.

[0012] The gel tape specially used for radiotherapy MRI simulation positioning as described above: the notches at the ends of two adjacent tearing portions are staggeredly distributed along both sides of the length direction of the release paper.

[0013] The gel tape specially used for radiotherapy MRI simulation positioning as described above: the tearing portion is provided with a tearing opening at one end thereof facing the notch.

[0014] The special gel tape for radiotherapy MRI simulation positioning as described above: the tearing opening is arranged in a "V"-shaped structure.

[0015] The gel tape specially used for radiotherapy MRI simulation positioning as described above: the diameter of the silica gel ball is 2 mm.

[0016] The gel tape specially used for radiotherapy MRI simulation positioning as described above: the adhesive piece is provided with a diaphragm layer, a base fabric layer, an antibacterial layer, a sterile layer and a glue layer in sequence along the direction toward the release paper.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The silicone ball and cross-marking lines are used to locate the target area of ​​the radiotherapy tumor, improving the positioning accuracy. At the same time, the pinching part does not stick to the release paper, which makes it easy for the operator to quickly find the corner of the sticker and pinch the sticker with their fingers to tear it off. This effectively eliminates the problem of sticker deformation caused by fingers or other tools. At the same time, the pinching parts on two adjacent stickers are staggered, so that when the previous sticker is torn off, the second sticker will not be torn off, which effectively prevents waste.

[0019] Adding high molecular weight hydrogel to the antibacterial layer and the sterile layer can effectively block the adhesion of bacteria, fungi, etc. to tissue cells while maintaining the permeability of nutrients such as water, inorganic salts, amino acids, low-level sugars and lipids.
