Description

Technical Field

[0001] This utility model relates to a medical auxiliary material, specifically, to a polymer radiotherapy positioning membrane that is easy to position. Background Technology

[0002] A radiotherapy positioning mold is a unique consumable used during radiotherapy. It is a special polymer plastic that deforms when placed in hot water at 60°C and hardens quickly after cooling. Utilizing this property, a mold can be made to fit the patient's body contour, fixing the patient to the bed and preventing movement during radiotherapy. Currently, there are many radiotherapy positioning molds on the market. For example, Chinese patent CN219630464U discloses a radiotherapy positioning mold comprising a thermoplastic film and a frame. In use, the thermoplastic film and frame are first immersed in hot water to soften the film, then shaped, and finally hardened. However, this positioning mold also has the following drawbacks: 1. When applied to the head and shoulder area, where the head and neck are concave, the natural deformation of the thermoplastic film makes it difficult to conform to the concave position, requiring manual pressing little by little. During manual pressing, the positioning film has already deformed, making it difficult to ensure that the pressing position is in a straight line; 2. During the shaping process, the side of the thermoplastic film without the frame tends to shrink inward, requiring careful manual pulling.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a polymer radiotherapy positioning membrane that facilitates positioning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A polymer radiotherapy positioning membrane for easy positioning, the radiotherapy positioning membrane is a head, shoulder and neck positioning membrane, the radiotherapy includes a thermoplastic membrane and a positioning frame set on the edge of the thermoplastic membrane, several sets of positioning strips are evenly arranged in the transition area between the head and the shoulder of the thermoplastic membrane, each set includes multiple positioning strips that are parallel to each other and evenly arranged, with gaps between two adjacent positioning strips, and two positioning strips are close to the positioning frame.

[0006] The positioning strip is made of the same material as the thermoplastic film, and it is a strip-shaped protrusion set on the upper side of the thermoplastic film.

[0007] The positioning strip is bonded to the upper side of the thermoplastic film. The positioning strip is a flexible, stretchable, strip-shaped protrusion.

[0008] At least one set of positioning strips near the shoulder of the thermoplastic film is connected by a transverse connecting strip, which is also a flexible and stretchable strip-shaped protrusion.

[0009] Three sets of positioning strips are provided on the upper side of the thermoplastic film.

[0010] The three sets of positioning strips are arranged from top to bottom, with the bottom set of positioning strips close to the shoulder.

[0011] The positioning frame includes an upper frame and a lower frame, with a thermoplastic film located between the upper and lower frames. The upper frame, thermoplastic film, and lower frame are fixedly connected. Several positioning posts are evenly arranged on the positioning frame, and each positioning post has a pull-out plate on its lower side.

[0012] A set of positioning strips is also provided on the lower side of the thermoplastic film corresponding to the open side of the positioning frame. The upper sides of each positioning strip are connected by a horizontal connecting strip, and a push-pull plate is provided on the upper side of the horizontal connecting strip.

[0013] Compared to existing technologies, the advantages of this invention are that it provides a simple and rationally designed polymer radiotherapy positioning membrane that facilitates positioning.

[0019] like Figure 1-2 As shown, a polymer radiotherapy positioning membrane for easy positioning is provided. The radiotherapy positioning membrane is a head, shoulder and neck positioning membrane. The radiotherapy includes a thermoplastic membrane 1 and a positioning frame 2 set on the edge of the thermoplastic membrane 1. Several sets of positioning strips 4 are evenly arranged in the transition area between the head and shoulder of the thermoplastic membrane 1. Each set includes multiple positioning strips 4 that are parallel to each other and evenly arranged. There is a gap between two adjacent positioning strips 4, and two positioning strips 4 are close to the positioning frame 2.

[0020] This easily positioned polymer radiotherapy positioning membrane has a simple and rational design, with multiple positioning strips between the head and shoulders to reduce the difficulty of shaping. In practical use, the radiotherapy positioning membrane is first softened by heating (currently, most are softened by immersion in hot water). Then, corresponding to the patient's head and shoulder positions, the radiotherapy positioning membrane is pressed downwards to fix the positioning frame to the medical bed. Finally, the radiotherapy positioning membrane is pressed to conform to the neck, and the open side of the positioning frame is adjusted. During the shaping process, the thermoplastic film can be pressed close to the neck by pressing the positioning strips between the head and shoulders.

[0021] In one embodiment, the positioning strip 4 is made of the same material as the thermoplastic film 1. The positioning strip 4 is a strip-shaped protrusion disposed on the upper side of the thermoplastic film 1, and the positioning strip 4 and the thermoplastic film 1 are integrally formed.

[0022] In one embodiment, the positioning strip 4 is bonded to the upper side of the thermoplastic film 1, and the positioning strip 4 is a flexible, stretchable strip-shaped protrusion. Specifically, it can be made of a polymer material such as rubber, which can change shape with the thermoplastic film.

[0023] In one embodiment, at least one set of positioning strips 4 near the shoulder of the thermoplastic film 1 are connected by a transverse connecting strip 5, which is also a flexible and stretchable strip protrusion for easy position reference.

[0024] In one embodiment, three sets of positioning strips 4 are provided on the upper side of the thermoplastic film 1.

[0025] In one embodiment, three sets of positioning strips 4 are arranged sequentially from top to bottom, with the bottommost set of positioning strips 4 close to the shoulder, and the bottommost positioning strips are connected by a transverse connecting strip.

[0026] In one embodiment, the positioning frame 2 includes an upper frame and a lower frame, with a thermoplastic film 1 located between the upper and lower frames. The upper frame, thermoplastic film 1, and lower frame are fixedly connected. A plurality of positioning posts are evenly arranged on the positioning frame 2, and each positioning post has a pull-out plate 3 on its lower side. During use, the positioning posts of the positioning frame 2 are inserted into corresponding insertion holes on the medical bed. Specifically, the positioning posts can be commonly used threaded posts (rotatably connected to the positioning frame), and the insertion holes can be threaded holes, with the positioning posts threadedly connected to the insertion holes.

[0027] In one embodiment, a set of positioning strips 4 is also provided on the lower side of the thermoplastic film 1 corresponding to the open side of the positioning frame 2 to prevent large-area curling of the edge of the thermoplastic film; the upper sides of each positioning strip 4 are connected by a transverse connecting strip 5, and a push-pull plate 6 is provided on the upper side of the transverse connecting strip 5. During the shaping process, the push-pull plate can be slowly pulled to drag the edge of the thermoplastic film. After the shaping is completed, the push-pull plate can be cut off with scissors.

[0028] The above embodiments can be combined with each other.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
