Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy equipment, in particular to an open-hole head and neck radiotherapy mask. Background Art

[0002] During radiotherapy for head and neck tumors, in order to achieve precise radiotherapy effects, it is necessary to fix the head and neck with a thermoplastic film to avoid head displacement during treatment and affect the treatment effect. The specific process is generally to apply the heated positioning film material to the patient's head and neck, the heating temperature is about 65-70°C, and the positioning film material is used to fit the contour of the patient's head and neck by its fluidity, and then let it stand for about 15 minutes, the thermoplastic film is formed, and after the forming is completed, it is removed and the production is completed. After the thermoplastic film is formed, the surface is filled with a large number of air holes of about 0.2cm*0.2cm for breathing. Conventional thermoplastic film masks have a strong sense of oppression on the patient's head and neck. Patients generally report varying degrees of discomfort. For younger patients and those with low compliance, they even resist thermoplastic film masks. At the same time, the structural stability of conventional thermoplastic films is low, and they are prone to deformation during the course of treatment, affecting the accuracy of treatment.

[0017] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0019] like Figure 1 and Figure 2 As shown, a specific embodiment of the utility model provides an open-hole head and neck radiotherapy mask, which is used to fix the head during radiotherapy, has high comfort and high structural strength; specifically includes a mask body 100, and the mask body 100 is provided with a clearance opening 110 corresponding to the human mouth, nose and eyes; the mask body 100 is provided with stress-bearing holes 120 arranged at intervals corresponding to the edge of the human face; the mask body 100 is provided with reinforcing ribs 130 arranged at intervals above the mask body 100, and each reinforcing rib 130 is adapted to the curvature of the mask body 100 and fits with the upper surface of the mask body 100; the outer edge of the mask body 100 is provided with a connecting portion 140, and the connecting portion 140 is detachably connected to the base 200.

[0020] like Figure 1 and Figure 2 As shown, through the above-mentioned settings, the present embodiment presets a clearance opening 110 on the mask body 100, and the clearance opening 110 is set corresponding to the patient's eyes, mouth and nose areas, so as to ensure that the patient can breathe smoothly and reduce the patient's discomfort as a whole during wearing; in order to ensure the overall structural strength of the mask body 100, the present embodiment sets the force-bearing holes 120 on the outside of the mask body 100, and the reinforcing rib 130 structure is designed to strengthen the force-bearing points of the mask. The reinforcing rib 130 structure is along the mask body 100 to prevent the mask body 100 from deforming. On the premise of ensuring that the mask is stable and not deformed, the comfort is improved and the compliance of radiotherapy is guaranteed; when in use, the mask body 100 needs to be connected to the base 200, and the base 200 supports the patient's neck area. A head and neck accommodating space is formed between the mask body 100 and the base 200. The mask body 100 is detachable and separable from the base 200 to achieve convenient disassembly and assembly, thereby improving the convenience of use.

[0021] As mentioned above, the mask body 100 is worn on the patient's face when in use, and a flexible contact pad 300 is provided on the inner side of the mask body 100 corresponding to the yield opening 110; when the flexible contact pad 300 contacts the patient's eyes and mouth and nose area, the comfort of the mask body 100 after being fixed can be improved.

[0022] like Figure 1 and Figure 2 As shown, in order to further improve the structural strength of the mask body 100, a plurality of stress protrusions 150 arranged at intervals and vertically arranged are provided on the outer side of the mask body 100 in this embodiment. By providing the stress protrusion 150 structure, deformation of the outer side of the mask body 100 can be avoided.

[0023] As mentioned above, the mask body 100 needs to be connected to the base 200. In order to ensure the position accuracy of the connection, the present embodiment provides spaced connection protrusions 160 on the outer edge of the mask body 100, and the connection protrusions 160 are inserted into the positioning holes provided on the surface of the base 200. The connection protrusions 160 can be inserted into the positioning holes to achieve positioning connection; at the same time, the present embodiment also provides a plurality of fixing buckles 400 on the upper surface of the base 200 corresponding to the outer edge of the mask body 100. The fixing buckle 400 structure can further fix the mask body 100 after the base 200 and the mask body 100 form a positioning connection.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, an elastic support pad 500 for supporting the human neck is provided at the bottom of the base 200, and the elastic support pad 500 is fixed to the inner bottom of the base 200 by Velcro. After the base 200 is connected to the mask body 100, the elastic support pad 500 at the inner bottom of the base 200 can support the patient's neck, and the support pad is connected to the base 200 by Velcro, which is convenient for disassembly.
