Description

Technical Field

[0001] This utility model relates to the field of medical consumables technology, specifically a medical positioning film that is easy to demold and disassemble. Background Technology

[0002] In radiotherapy, medical positioning membranes are a special type of plastic consumable used to assist in positioning and fixing the patient's body position. As an important auxiliary tool in radiotherapy, they can help improve the accuracy and treatment effect of radiotherapy, while reducing damage to normal tissues. In addition, medical positioning membranes also have a certain degree of plasticity. They can be softened in hot water and stretched and shaped at will to adapt to the body shape and needs of different patients.

[0003] Currently, existing medical positioning films typically use multiple Latin-type clips to fix the position after the consumables are placed on the patient. However, considering the large number of clips, after accurate positioning, each clip needs to be removed to disassemble the consumables, which is cumbersome and makes it difficult for medical staff to quickly demold and remove the consumables. Therefore, a medical positioning film that is easy to demold and disassemble is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a medical positioning film that is easy to demold and disassemble, in order to solve the problem mentioned in the background art that the existing medical positioning film is cumbersome to disassemble and is not conducive to medical staff quickly demolding and disassembling the consumables.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A medical positioning membrane that is easy to demold and disassemble includes a limiting frame, a support plate fixedly connected to the lower left side of the limiting frame, a flip plate abutting above the support plate, rotating rollers fixedly connected to the front and rear ends of the right side of the flip plate, a movable square fixedly connected to the left side of the flip plate, an inner plate fixedly connected to the upper inner side of the movable square, a limiting slide plate slidably connected to the lower inner side of the movable square, a guide rod fixedly connected to the top of the limiting slide plate and slidably connected to the inner plate, a long handle fixedly connected to the top of the guide rod, a spring sleeved on the outside of the guide rod, a pin block fixedly connected to the bottom of the limiting slide plate, limit strips fixedly connected to both sides of the limiting slide plate, and the top of the spring and the bottom of the inner plate fixedly connected together.

[0007] Preferably, the limiting clamping frame has a "U" shaped structure, and a positioning film body is clamped inside the limiting clamping frame. The width of the positioning film body is equal to the width of the limiting clamping frame.

[0008] Preferably, the right half of the rotating roller is disposed in a square groove structure opened on the left end face of the limiting clamping frame, and the limiting clamping frame and the rotating roller are rotatably connected together.

[0009] Preferably, the connection between the flap and the movable frame forms an "L" shape, and the movable frame and the limiting strip are slidably connected together, with a total of two limiting strips.

[0010] Preferably, the bottom end of the spring and the top end of the inner plate are fixedly connected together, and a total of 6 pin blocks are provided, which are located inside the movable frame.

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

[0012] In this invention, the medical positioning membrane, which is designed with a rotating roller, a flip plate, a movable frame, an inner plate, a guide rod, a long handle, a limiting slide plate, a limiting strip, a pin block, and a spring, facilitates the installation and removal of the membrane. When assisting patients in positioning for radiotherapy, the membrane, under the connection and constraint of the support plate and the limiting frame, utilizes a spring-loaded positioning structure composed of the rotating roller, flip plate, movable frame, inner plate, guide rod, long handle, limiting slide plate, limiting strip, pin block, and spring. This replaces the commonly used Latin-type buckles for installation and removal, enabling the medical positioning membrane to be easily disassembled and removed during actual use. This allows medical personnel to quickly remove medical consumables, improving their usability. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A medical positioning membrane that is easy to demold and disassemble includes a limiting frame 1. A support plate 2 is fixedly connected to the lower left side of the limiting frame 1. A flip plate 4 is abutted above the support plate 2. Rollers 3 are fixedly connected to the front and rear ends of the right side of the flip plate 4. A movable square frame 5 is fixedly connected to the left side of the flip plate 4. An inner plate 6 is fixedly connected to the upper inner side of the movable square frame 5. A limiting slide plate 9 is slidably connected to the lower inner side of the movable square frame 5. A guide rod 7 is fixedly connected to the top of the limiting slide plate 9 and slidably connected to the inner plate 6. A long handle 8 is fixedly connected to the top of the guide rod 7. A spring 12 is sleeved on the outside of the guide rod 7. A pin block 11 is fixedly connected to the bottom of the limiting slide plate 9. Limit strips 10 are fixedly connected to both sides of the limiting slide plate 9. The top of the spring 12 is fixedly connected to the bottom of the inner plate 6.

[0021] like Figure 1 and Figure 3 As shown, the limiting clamp frame 1 has a "U" shaped structure. The positioning membrane body 13 is clamped inside the limiting clamp frame 1. The width of the positioning membrane body 13 is equal to the width of the limiting clamp frame 1. When the positioning membrane body 13 is stretched for body positioning, the limiting clamp frame 1 serves to limit the positioning membrane body 13 at the side. The right half of the rotating roller 3 is set in the square groove structure opened on the left end face of the limiting clamp frame 1. The limiting clamp frame 1 and the rotating roller 3 are rotatably connected together. This structure facilitates the flipping and adjustment of the spring-loaded positioning structure, so as to make it easier for medical personnel to more accurately align the multi-hole base and fix the consumables.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the connection between the flip plate 4 and the movable frame 5 forms an "L" shaped structure. The movable frame 5 and the limiting strip 10 are slidably connected together. There are two limiting strips 10. When the pin block 11 moves up and down, the sliding connection between the limiting strip 10 and the movable frame 5 can play a guiding and auxiliary role. The bottom end of the spring 12 is fixedly connected to the top end of the inner plate 6. There are six pin blocks 11. The pin blocks 11 are set inside the movable frame 5. The multiple pin blocks 11 are set one-to-one with the holes and slots on the multi-hole base, which is conducive to the spring-loaded positioning structure being able to accurately connect to the multi-hole base by plugging.

[0023] Workflow: The medical consumables of this invention require use in conjunction with a multi-hole base fixed to a CT bed (the arrangement of the multiple slots on the multi-hole base and the arrangement of the pin blocks 11 must be consistent). Before use, the consumables need to be fully softened in hot water. Before radiotherapy, this medical positioning film is used to position and fix the patient's body. As the medical personnel remove the softened medical positioning film from the hot water and place it on the patient, they simultaneously pull the long handle 8 upwards according to the patient's body shape, causing the multiple pin blocks 11 to retract into the movable frame 5. The movable frame 5 is then flipped and adjusted using the flip plate 4 and the rotating roller 3 to ensure alignment with the slots for subsequent fixation. First, stretch the positioning membrane body 13 outwards until it is fully stretched and aligned with the slot. Then, firmly grasp the long handle 8 and use the flip plate 4 and rotating roller 3 to reset and flip the movable square frame 5. Then, release the long handle 8, and the spring 12 will begin to rebound and reset. Under the guidance of the limiting strip 10, the limiting slide plate 9 with the pin block 11 will pop outwards. The pin block 11 will be inserted into the multi-hole base on the CT bed, thereby fixing the medical positioning membrane. When the radiotherapy position is completed and the molded medical positioning membrane needs to be removed, pull up the long handle 8. The guide rod 7 will stretch the limiting slide plate 9, the limiting strip 10 and the pin block 11 upwards. The pin block 11 will separate from the multi-hole base, thereby assisting medical personnel to quickly remove the medical positioning membrane.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
