Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a cross positioning sticker for radiotherapy. Background Art

[0002] Radiotherapy is a form of treatment that uses ionizing radiation. Its principle is to use the energy generated by radiation to destroy the chromosomes of cells, stop the cells from growing, and thus eliminate cancer cells that can divide and grow rapidly. It is a direct or auxiliary treatment for cancer. Before radiotherapy, position the patient so that the laser cross forms a projection at the appropriate position on the patient's body surface. Use a scratching fluid or a cross positioning sticker to mark the cross line at the projection of the laser cross. Use the cross line to establish a reference system for radiotherapy positioning, and finally determine the patient's target area through CT scanning. The cross positioning stickers commonly used in clinical practice are mainly cross-shaped adhesive tapes or adhesive strips that are torn off and pasted into a cross shape. For example, a radiotherapy body surface cross positioning line protective sticker with application number CN201820052342.1 includes a release paper layer and a cross-shaped marking line protective layer. The marking line protective layer includes a transparent protective film layer and an adhesive layer, and the center of the adhesive layer is hollowed out in a cross shape. The above common types of cross positioning stickers have the following shortcomings in actual applications:

[0003] When the cross positioning sticker is pasted, wrinkles or edge folding may occur easily during the pasting process because the protruding four sides are soft, which affects the flatness of the cross positioning sticker and makes subsequent positioning inconvenient. Utility Model Content

[0004] The utility model aims to provide a cross positioning sticker for radiotherapy, so as to solve the problem that the existing cross positioning sticker proposed in the above background technology is not convenient for fast and accurate sticking and use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cross positioning patch for radiotherapy, comprising a centering patch and a packaging structure arranged on the outside of the centering patch, the edge of the centering patch is fixedly provided with four crease edges, and cross edge stickers are fixedly provided on the four crease edges, a centering hemisphere is fixedly provided in the middle of the centering patch, and four cross positioning lines are fixedly provided on the periphery of the centering hemisphere, and the four cross positioning lines extend to the four cross edge stickers respectively, and a plurality of evenly distributed elliptical air holes are opened on the surface of the cross edge sticker, and a first bonding layer is fixedly provided on the bottom of the centering patch.

[0006] Preferably, the cross-edge sticker comprises a sterile non-woven fabric and a transparent protective film fixedly arranged on the outside of the sterile non-woven fabric, a second bonding layer is fixedly arranged on the inside of the sterile non-woven fabric, and a peeling base film is adhered to the inside of the second bonding layer; the sticker is easy to use.

[0007] Preferably, ruler scales are provided on both sides of the cross positioning line, and the cross positioning line is set to red; the positioning is accurate and eye-catching.

[0008] Preferably, the packaging structure includes a bottom paper plate and a packaging film matching the bottom paper plate; when the cross positioning sticker is not in use, it can be sealed and packaged, is not easy to get dirty and wrinkled, and has high flatness after pasting.

[0009] Preferably, the first bonding layer and the second bonding layer are both made of self-adhesive material; the bonding is stable and easy to tear off.

[0010] Preferably, the thickness of the centering sticker is set at 0.1-0.3 mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The cross positioning sticker is composed of a centering sticker and four cross side stickers. When in use, the cross sticker can be centered by the centering sticker, and then the cross side stickers are stretched and flattened in sequence to form a cross shape. The pasting is smooth and smooth, and it is not easy to have edge wrinkles or stick to each other. The flatness is high after pasting. The surface of the cross sticker is provided with a red cross positioning line to make it coincide with the laser cross, which can improve the accuracy of positioning and is easy to use.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-3The utility model provides a cross positioning sticker for radiotherapy, comprising a centering sticker 1 and a packaging structure arranged outside the centering sticker 1, four fold edges 6 are fixedly arranged on the edge of the centering sticker 1, and cross edge stickers 2 are fixedly arranged on the four fold edges 6, a centering hemisphere 5 is fixedly arranged in the middle of the centering sticker 1, and four cross positioning lines 3 are fixedly arranged on the periphery of the centering hemisphere 5, and the four cross positioning lines 3 extend to the four cross edge stickers 2 respectively. A plurality of evenly distributed elliptical air holes 7 are opened on the surface of the cross edge sticker 2, a first bonding layer 10 is fixedly arranged on the bottom of the centering sticker 1, and ruler scales 4 are arranged on both sides of the cross positioning line 3, and the cross positioning line 3 is set to red, and the packaging structure comprises a bottom sticker board 8 and a packaging film 9 matching the bottom sticker board 8;

[0019] When in use, make the centering hemisphere 5 coincide with the center of the cross projection, then press the centering sticker 1 to stick and fix it, then turn over the cross side sticker 2 in turn, tear off the peeling base film 14 from the bottom of the cross side sticker 2, stretch and flatten the cross side sticker 2, and stick and fix the cross side sticker 2. After sticking, the elliptical air holes 7 can be used to increase the air permeability of the cross sticker, so that the local part of the patient is not prone to stuffiness, and it is comfortable to use.

[0020] See also Figure 1 and Figure 2 Further, the cross-edge sticker 2 includes a sterile non-woven fabric 12 and a transparent protective film 11 fixedly arranged on the outside of the sterile non-woven fabric 12, a second laminating layer 13 is fixedly arranged on the inside of the sterile non-woven fabric 12, a peeling bottom film 14 is pasted on the inside of the second laminating layer 13, the first laminating layer 10 and the second laminating layer 13 are both made of self-adhesive materials, and the thickness of the centering sticker 1 is set at 0.1-0.3mm;
