Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a vacuum shaping pad used for tumor radiotherapy. Background Art

[0002] During radiotherapy, maintaining a stable and secure patient position is crucial to ensure treatment accuracy and minimize damage to surrounding normal tissue. Existing vacuum-shaped cushions are typically integrally molded and have a single exhaust port. While these cushions provide effective patient positioning, they still need to be improved in terms of ease of use, patient comfort, and positioning accuracy. For example, positioning is limited for patients with soft tissue sarcomas in the arm, who require elevated arms for beam placement but whose shoulders and necks cannot withstand such elevation.

[0003] Therefore, there is an urgent need to develop a vacuum shaping pad that is more efficient, comfortable and easy to use. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and provide a vacuum shaping pad for tumor radiotherapy.

[0005] The specific technical solutions adopted in this utility model are as follows:

[0010] Preferably, the left cavity, the middle cavity and the right cavity are further provided with a plurality of foldable indentations, through which the supports therein are fixed to avoid local accumulation of the supports resulting in reduced shaping effect.

[0011] Preferably, the sealing strip is made of polyvinyl chloride.

[0012] Preferably, the gas charging and discharging port is an air valve.

[0013] Preferably, the sealing cover is a screw-mouth cover.

[0014] Preferably, the inflation and deflation ports are connected to an external vacuum pump to achieve inflation and deflation of the left cavity, the middle cavity and the right cavity.

[0015] Preferably, a scale is fixed on one side of the neck extension area for judging whether the vacuum shaping pad is leaking during use, and a scale buckle matching the scale is fixed on the other side; by measuring the total circumference of the user's neck and the vacuum shaping pad at a fixed point, it is judged whether the vacuum shaping pad is completely fitted to the neck, thereby judging whether the vacuum shaping pad is leaking.

[0016] Furthermore, the scale is a tape measure.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The vacuum shaping cushion provided by this utility model adopts a three-chamber separation structure, which is divided into a left cavity, a middle cavity, and a right cavity by a dividing edge. Each cavity is filled with a support and independently evacuated, and the vacuum state is quickly adjusted. It is suitable for independent shaping of each partition, improving adaptability and efficiency. Styrene plastic is used as a support to ensure that the vacuum shaping cushion fits the patient's body shape tightly and provides stable support.

[0019] (2) Each cavity of the vacuum shaping pad provided by the present invention is also provided with a foldable indentation, which cooperates with a non-return channel to ensure that the support inside the cavity does not collapse during support positioning, avoids the reduction of the plastic effect caused by local accumulation of the support, and improves the positioning stability of the overall vacuum shaping pad.

[0020] (3) The neck extension area of the vacuum shaping cushion provided by the present invention is also equipped with a scale and a matching scale buckle to measure the fit between the patient and the vacuum cushion, thereby preventing the vacuum cushion from moving during use and causing the radiation to deviate from the irradiation area. While the model is fixed, it can also be combined with a headrest according to individual conditions to further reduce positioning errors and adapt to different patient positions.

[0022] In the figure: bed board positioning point 1, scale 2, scale buckle 3, neck extension area 4, sealing cover 5, inflation and deflation port 6, foldable indentation 7, left cavity 8, middle cavity 9, right cavity 10, dividing edge 11, sealing strip 12. DETAILED DESCRIPTION

[0023] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features of the various embodiments of the present invention may be combined accordingly, provided that there is no conflict between them.

[0024] like Figure 1 As shown in FIG. , as a preferred embodiment of the present invention, this embodiment provides a vacuum shaping cushion for tumor radiotherapy. The vacuum shaping cushion comprises, from left to right, a left cavity 8, a middle cavity 9, and a right cavity 10. The left cavity 8, the middle cavity 9, and the right cavity 10 are independent of each other, with a dividing edge 11 provided between the left cavity 8 and the middle cavity 9, and between the middle cavity 9 and the right cavity 10. A neck extension area 4 extends upward from the middle cavity 9 to secure the user's neck.

[0025] Because the vacuum shaping cushion is a commonly used device for positioning during tumor radiotherapy, the left cavity 8, the middle cavity 9, and the right cavity 10 all require support. In this embodiment, the support is made of polystyrene plastic particles. Polystyrene plastic particles have excellent fluidity and shaping ability. After being adjusted to a position that suits the patient's body shape, they can be fixed by vacuuming. Of course, those skilled in the art may also use other polymer particles as needed.

[0026] In this embodiment, the left cavity 8, the middle cavity 9 and the right cavity 10 of the vacuum shaping pad are all made of soft pads made of polyvinyl chloride (PVC). This material has good flexibility and durability, and can also ensure a good sealing state during the vacuuming process.

[0027] In the device provided by the present invention, the peripheries of the left cavity 8, the middle cavity 9 and the right cavity 10 are respectively provided with sealing strips 12 for preventing air leakage. In this embodiment, the sealing strips 12 are all made of polyvinyl chloride (PVC).

[0028] In order to prevent the polystyrene plastic particles filled in the left cavity 8, the middle cavity 9, and the right cavity 10 from being locally accumulated during use, which would reduce the plastic effect, in this embodiment, a plurality of foldable indentations 7 are provided on the left cavity 8, the middle cavity 9, and the right cavity 10. The foldable indentations 7 can further partition and fix the polystyrene plastic particles in each cavity.

[0029] The device provided by the present utility model is that the left cavity 8, the middle cavity 9 and the right cavity 10 are connected to the external vacuum pump through the inflation and deflation ports 6, so as to realize the inflation and deflation of the left cavity 8, the middle cavity 9 and the right cavity 10. Each inflation and deflation port 6 is provided with a sealing cover 5 for sealing. In this embodiment, the inflation and deflation port 6 adopts an air valve. When the vacuum pump inflates the cavity, compressed air enters through the hollow part of the air valve. There is a spring in the air valve. When the air pressure is large enough, the spring is compressed, the air valve opens, and air enters the cavity. When the inflation stops, the spring in the air valve automatically returns to its original position, closes the air valve, and prevents air from flowing back from the cavity. When deflation is required, just press the hole in the middle of the air valve. A matching spiral nozzle cover is provided on the outside of the air valve to prevent air leakage.

[0030] like Figure 1 As shown, in the device provided by the present invention, two bed board positioning points 1 are respectively set at the top of the neck extension area 4 and the bottom of the middle cavity 9, and the vacuum shaping pad is fixed to the corresponding position of the treatment bed through the bed board positioning points 1.

[0031] To determine if there are any leaks during use, this embodiment also features a scale 2, which can be a tape measure, on one side of the neck extension 4. A scale buckle 3, which matches the scale 2, is secured to the other side of the neck extension 4. The total circumference of the user's neck and the vacuum shaping cushion is measured at a fixed point to determine if the cushion fits the neck perfectly. If the total circumference measured during treatment is consistent with the initial total circumference, the cushion is considered leak-free.

[0032] The above-described embodiment is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Persons skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent substitution or equivalent transformation falls within the scope of protection of the present invention.
