Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically, it relates to a device for applying a protective agent to the vulva of cancer patients undergoing radiotherapy. Background Technology

[0002] In the process of radiotherapy for gynecological tumors, in order to reduce the damage of radiotherapy to the skin of the vulva, it is usually necessary to apply a protective agent.

[0003] However, existing application methods have many shortcomings. Traditional manual application makes it difficult to ensure the evenness of the protective agent application, easily resulting in excessive or insufficient application in certain areas, affecting the protective effect. Moreover, manual application makes it difficult to precisely control the amount of protective agent used, potentially leading to waste or inadequate protection. In addition, some existing application tools have poor versatility, cannot adapt well to the complex structure of the vulva, and their rough shapes may cause discomfort or even injury to patients during operation; furthermore, some existing application tools are extremely difficult to disassemble, causing considerable inconvenience for internal cleaning after use. Therefore, it is necessary to develop a specialized application device for vulvar protective agents used in gynecological tumor radiotherapy to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 6As shown, a vulvar protectant applicator for radiotherapy in cancer patients includes a reservoir 5 and an applicator shell 9. The upper end of the reservoir 5 is provided with a control mechanism, which includes a threaded cap 4. The inner side of the threaded cap 4 is provided with threads, which correspond to the threads on the outer periphery of the upper end of the reservoir 5 and are threadedly connected to it.

[0027] The lower end of the coating housing 9 has a roller groove 20 inside, and the coating housing 9 is equipped with a coating mechanism, which includes a coating roller 15. The coating roller 15 corresponds to the roller groove 20 and is movably connected with it.

[0028] In this design, the roller application method results in a more uniform application surface and a larger application area, increasing application efficiency and adaptability. At the same time, the rounded shape design addresses the technical problem that the surface may cause discomfort or even damage to patients during operation.

[0029] like Figures 1 to 6 As shown, in a specific embodiment, a first threaded sleeve 3 is fixedly sleeved at the center position of the threaded cap 4, and a threaded rod 2 is threadedly sleeved inside the first threaded sleeve 3. A control knob 1 is fixedly connected to the upper end of the threaded rod 2, and a piston 10 is fixedly connected to the lower end of the threaded rod 2. The outer diameter of the piston 10 corresponds to the inner diameter of the liquid storage tank 5 and is slidably sealed with it.

[0030] In this setup, by rotating the control knob 1, the piston 10 is pushed down, and the protective agent inside the storage tank 5 is sent into the diversion channel 13 through the conduit 11.

[0031] like Figures 1 to 6 As shown, in a specific embodiment, the shaft at one end of the applicator roller 15 is movably connected to the applicator housing 9. The applicator housing 9 has a flow channel 13 inside, and a liquid outlet channel 14 is provided at the lower end of the flow channel 13. The lower opening of the liquid outlet channel 14 corresponds to the surface of the applicator roller 15.

[0032] In this setup, as the applicator roller 15 rotates, the liquid is evenly applied to the surface of the applicator roller 15 through the liquid outlet channel 14.

[0033] like Figures 1 to 6 As shown, in a specific embodiment, a magnetic plug 19 is fixedly connected to one end of the coating shell 9, and a quick-release cover 17 is provided at one end of the magnetic plug 19 of the coating shell 9. A magnetic insertion hole 16 is opened on the inner side of the quick-release cover 17, which corresponds to the magnetic plug 19 and is magnetically inserted with it. A sealing plug 18 is fixedly connected to the inner side of the quick-release cover 17, which corresponds to one end opening of the diversion channel 13 and is sealed with it. A shaft hole is opened at the lower inner end of the quick-release cover 17, which corresponds to the shaft of one end of the coating roller 15 and is movably sleeved with it.

[0034] Furthermore, this design incorporates a multi-section, quick-disassembly structure, facilitating thorough cleaning of the internal structure after use.

[0035] like Figures 1 to 6 As shown, in a specific embodiment, a viewing window 6 is provided on the tank body of the liquid storage tank 5, a transparent plate is fixedly installed inside the viewing window 6, liquid level scale is printed on the transparent plate, and a bendable and shaping hose 7 is fixedly connected to the lower end of the liquid storage tank 5, and a conduit 11 is installed inside the bendable and shaping hose 7.

[0036] In this setup, when using this device, the bendable shaping hose 7 is bent to a suitable angle as needed.

[0037] like Figures 1 to 6 As shown, in a specific embodiment, the lower end of the bendable and shaping hose 7 is fixedly connected to a connector 21. The connector 21 has a receiving groove inside, and a self-closing valve 12 is fixedly installed in the receiving groove. The connector 21 also has a liquid channel inside, and the upper end of the liquid channel is connected to the conduit 11. The upper end of the coating shell 9 has a mounting hole, and a second threaded sleeve 8 is fixedly fitted inside the mounting hole. The inner thread of the second threaded sleeve 8 corresponds to the thread on the outer side of the connector 21 and is threadedly fitted with it. The lower end of the liquid channel inside the connector 21 corresponds to the upper opening of the diversion channel 13.

[0038] In this configuration, the self-closing valve 12 only opens when liquid pressure is generated at the upper end. This design is intended to prevent the protective agent in the storage tank 5 from continuously flowing down due to gravity, thereby achieving better control of the liquid flow rate.

[0039] The implementation principle of the vulvar protective agent applicator for radiotherapy in cancer patients in this embodiment is as follows:

[0040] This invention employs a roller application method, resulting in a more uniform application surface and a larger application area, thus increasing application efficiency and adaptability. Furthermore, its smooth, rounded design addresses the technical issue of potential discomfort or even injury to patients during operation. Additionally, its multi-section, quick-disassembly design facilitates thorough cleaning of the internal structure after use.

[0041] When using this equipment, the flexible shaping hose 7 is bent to a suitable angle according to the requirements. Then, by rotating the control knob 1, the piston 10 is pushed down, and the protective agent inside the storage tank 5 is sent into the diversion channel 13 through the conduit 11. When the application roller 15 rotates, it is evenly applied to the surface of the application roller 15 through the liquid outlet channel 14. The self-closing valve 12 will only open when liquid pressure is generated at the upper end. It is designed to prevent the protective agent in the storage tank 5 from continuously flowing down due to gravity, so as to achieve better control of the liquid flow.
