Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a treatment device for shaving pubic hair in patients with pubic lice. Background Technology

[0002] Pubic lice is a common parasitic infection. Treatment relies on the application of antiparasitic drugs and the physical removal of the parasite. Currently, in clinical and personal care settings, general-purpose shaving tools are commonly used to remove pubic hair. However, in practice, these tools are too simplistic, only capable of cutting and completely lacking consideration for the immediate collection, containment, and disinfection of contaminants. The shaved pubic hair, along with the lice and eggs attached to it, easily disperses or adheres to blades, sinks, and the environment, becoming a source of secondary infection or environmental pollution. Disposing of shaved pubic hair is a challenging problem in both medical and home settings. Therefore, there is an urgent need for a shaving device that can automatically collect and contain contaminants to meet practical needs. Summary of the Invention

[0003] The present invention aims to provide a processing device for pubic hair removal in patients with pubic lice, so as to solve the problem that the current shaving devices cannot collect and store the pubic hair after shaving.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A device for shaving pubic hair in patients with pubic lice includes a power unit, a storage unit, and a shaving unit; The power unit is connected to the tail end of the storage unit. The power unit is equipped with a drive component to generate suction and draw air from the storage unit. The storage section is equipped with a fixed frame, which is equipped with a filter assembly to intercept pubic hair. The head end of the storage section is equipped with a one-way valve to prevent backflow. The bottom of the storage section is equipped with an auxiliary assembly, which is driven by a drive assembly to deliver medicine to the scraping section. The bottom surface of the scraping section is equipped with several blades for scraping pubic hair. The scraping section is equipped with a flow guide, which is connected to one end of the connecting tube and the other end of the connecting tube is connected to the head end of the storage section for sucking the scraped pubic hair into the storage section.

[0005] Furthermore, the drive assembly includes a miniature brushless fan and a control terminal disposed in the inner cavity of the power unit. The miniature brushless fan is controlled by the control terminal, which includes a battery and a control panel.

[0006] Furthermore, the auxiliary components include a medicine storage cylinder and a piston that is slidably disposed inside the medicine storage cylinder. The medicine storage cylinder is used to store the medicine liquid. The tail end interface of the medicine storage cylinder is connected to one end of the air pipe. The air pipe is located at the bottom of the power unit and communicates with the inner cavity of the power unit. The head end interface of the medicine storage cylinder is connected to one end of the medicine delivery pipe. The other end of the medicine delivery pipe communicates with the cavity of the scraping part. The bottom surface of the scraping part is provided with several micro-holes, which communicate with the cavity for discharging the medicine liquid.

[0007] Furthermore, the power unit has several vent holes that communicate with the inner cavity of the power unit to discharge air. A threaded sleeve is fitted onto the power unit, and the threaded sleeve engages with the threads on the surface of the power unit.

[0008] Furthermore, a guide block is provided in the inner cavity of the power unit to guide the airflow to the vent hole, and sealing sleeves are provided at the interfaces at both ends of the medicine storage cylinder and the connection points of the air pipe and the medicine delivery pipe.

[0009] Furthermore, the filtration assembly includes a pre-filter and a post-filter mounted on a fixed frame. The pre-filter is made of medical-grade HEPA material, and the front section of the post-filter is cured with disinfectant, while the rear section is filled with an activated carbon layer.

[0010] Furthermore, the mounting bracket is equipped with several diagonal braces.

[0011] Furthermore, the one-way valve includes a fixed shaft fixedly installed in the storage section and two sets of baffles rotatably installed on the fixed shaft. A spring plate is provided on the fixed shaft. The spring plate is released from the baffles to close the baffles at the interface of the storage section.

[0012] The principles and beneficial effects of the technical solution are as follows: This invention provides a device for shaving pubic hair in patients with pubic lice. 1. The negative pressure suction generated by the drive component of the power unit removes pubic hair. After the scraping part removes the pubic hair, the suction at the opening of the guide shroud draws the pubic hair into the guide shroud and then transports it to the storage part through the connecting pipe. It is intercepted by the filter component and thus stored in the storage part for collection, preventing the scraped pubic hair from scattering and causing pollution. After use, the one-way valve automatically closes, thereby sealing the interface of the storage part and achieving sealing. 2. The medicine storage cylinder can store the medicine liquid. Part of the gas discharged from the drive component enters the medicine storage cylinder through the air pipe, thereby pushing the piston to move. The medicine is pushed into the scraping part through the medicine delivery pipe and finally sprayed out through the micro-hole, realizing the simultaneous scraping and medicine application. 3. By rotating the threaded sleeve, its position on the power unit is adjusted, thereby covering the vent hole part, changing the number of working vent holes, changing its exhaust speed, thereby adjusting the pressure inside the power unit, and thus changing the air pressure entering the trachea, adjusting the piston movement speed, and thus adjusting the drug delivery rate. 4. The pre-filter intercepts pubic hair and dander, collecting them in the storage section. The post-filter disinfects and deodorizes the gas passing through the pre-filter, ensuring that the gas discharged from the power unit is clean and odorless, thus guaranteeing the safety and comfort of the device.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figures 1-9 As shown, a treatment device for shaving pubic hair in patients with pubic lice includes a power unit 1, a storage unit 2 and a shaving unit 3; The power unit 1 and the storage unit 2 are connected at their tail ends by a threaded structure. The power unit 1 is equipped with a drive assembly to generate negative pressure suction and draw air from the storage unit 2. The storage section 2 is equipped with a fixing frame 201, which is equipped with a filter assembly to intercept pubic hair and allow gas to pass through. The head end of the storage section 2 is equipped with a one-way valve to prevent backflow. In the initial state, the one-way valve is closed. When the drive assembly generates negative pressure suction, the one-way valve is opened by suction, thereby allowing pubic hair and dander to enter the storage section 2. The bottom of the storage section 2 is equipped with an auxiliary assembly that can store medicine. The auxiliary assembly is driven by the drive assembly. Part of the gas discharged by the drive assembly pushes the internal moving parts of the auxiliary assembly to move, which is used to deliver medicine to the scraping section 3. The bottom surface of the scraping section 3 is provided with several blades for scraping pubic hair. A guide hood 302 is provided on the scraping section 3. The opening of the guide hood 302 is located above the scraping section 3 and is in the same direction as the scraping direction to attract most of the pubic hair. A through groove is provided on the scraping section 3, which is connected to the inside of the guide hood 302 to attract dandruff and scraped fine pubic hair. The guide hood 302 is connected to one end of the connecting pipe 301. The diameter of the connecting pipe 301 gradually decreases near the guide hood 302. By reducing the cross-sectional area, the airflow velocity is increased, so that a greater suction force can be generated at the opening of the guide hood 302. At the same time, the connecting pipe 301 is Z-shaped, so that the scraping section 3 and the storage section 2 are not on the same axis, which facilitates the scraping operation. The other end of the connecting pipe 301 is connected to the head end of the storage section 2 through a threaded structure to draw the scraped pubic hair into the storage section 2.

[0015] The storage section 2 and scraping section 3 of this device are disposable sterile consumables, and are equipped with two caps that are threaded to fit the interface of the storage section 2. To use, remove them from the sterile packaging bag, connect the connecting tube 301 to the storage section 2, and then connect the storage section 2 to the power section 1 to complete the assembly of the device. Open the drive component inside the power section 1, adjust it to a suitable negative pressure suction, and hold the main body consisting of the power section 1 and storage section 2 with one hand. The pubic hair can then be scraped off using the blade at the bottom of the scraping section 3. When scraping the pubic hair, the scraping section 3 squeezes the hair, forcing it to lie flat in the scraping direction in front of the opening of the guide hood 302. Once the pubic hair is cut by the blade, it is immediately sucked into the guide hood 302 by suction. Skin flakes and fine pubic hair are sucked into the guide hood 302 through the through-slot of the scraping section 3, and then transported to the storage section 2 through the connecting tube 301. After being intercepted by the filter component, they remain inside the storage section 2. The gas carrying pubic hair can pass through the filter assembly, enter the power unit 1, and then be discharged. This allows the device to collect pubic hair while scraping it, preventing it from scattering and requiring subsequent cleaning. After scraping, the drive assembly continues to draw in negative pressure for a period of time, allowing any remaining pubic hair and dander in the guide shroud 302 and connecting pipe 301 to enter the storage unit 2. After stopping the drive assembly, the one-way valve resets, sealing the opening of the storage unit 2 to prevent leakage. The power unit 1 can then be removed from the storage unit 2 for disinfection. The connecting pipe 301 can then be removed from the storage unit 2, and the scraping unit 3 can be discarded. By screwing the caps that match the threads at both ends of the storage unit 2, the entire storage unit 2 can be sealed, effectively preventing it from becoming a secondary source of infection or environmental pollution. Furthermore, the user does not need to collect and process the pubic hair separately afterward, making the device more convenient to use.

[0016] In this embodiment, the drive assembly includes a miniature brushless fan 101 disposed within the inner cavity of the power unit 1 and a control terminal. The miniature brushless fan 101 is controlled by the control terminal, which includes a battery and a control panel. Powered by the battery, no external wires are required, avoiding interference with operation and facilitating use. The rotational speed of the miniature brushless fan 101 can be controlled via the control panel, thereby generating appropriate negative pressure suction to attract pubic hair.

[0017] In this embodiment, the auxiliary component includes a medicine storage cylinder 202 and a piston 2021 slidably disposed inside the medicine storage cylinder 202. The medicine storage cylinder 202 is used to store the medicine liquid. The tail end interface of the medicine storage cylinder 202 is connected to one end of the air pipe 103. The air pipe 103 is disposed at the bottom of the power unit 1 and communicates with the inner cavity of the power unit 1. The head end interface of the medicine storage cylinder 202 is connected to one end of the medicine delivery pipe 303. The other end of the medicine delivery pipe 303 communicates with the cavity 304 of the scraping part 3. The bottom surface of the scraping part 3 is provided with a plurality of micro holes 305, which communicate with the cavity 304 for discharging the medicine liquid. When adding medication to the drug reservoir 202, its front end is connected to a syringe containing the medication, thereby pushing the medication into the drug reservoir 202. Most of the gas discharged by the miniature brushless fan 101 is discharged outside the power unit 1, and a portion of the gas enters the drug reservoir 202 through the air pipe 103, pushing the piston 2021 to move and squeeze the medication. The medication then enters the cavity 304 of the scraping unit 3 through the delivery tube 303, and is finally sprayed out through the micro-hole 305 onto the patient's skin surface, achieving simultaneous scraping and medication application, reducing the burden on medical staff.

[0018] In this embodiment, the power unit 1 has several vent holes 104, which communicate with the inner cavity of the power unit 1 to discharge air. A threaded sleeve 102 is fitted onto the power unit 1, and the threaded sleeve 102 engages with the threads on the surface of the power unit 1. By rotating the threaded sleeve 102, its position on the power unit 1 is adjusted, thereby partially covering the vent holes 104, changing the number of working vent holes 104, and thus changing the exhaust speed per unit time. When the threaded sleeve 102 covers more vent holes 104, the exhaust efficiency decreases, while the efficiency of the airflow generated by the micro brushless fan 101 remains unchanged, resulting in increased pressure in the inner cavity of the power unit 1. Consequently, the air pressure entering the trachea 103 is not high, and the piston 2021 moves faster, resulting in a larger dose of medication per unit time. Conversely, when the threaded sleeve 102 covers fewer vent holes 104, the dose of medication decreases, thereby adjusting the medication rate to adapt to the operating speed of different medical personnel.

[0019] In this embodiment, a guide block 105 is provided in the inner cavity of the power unit 1 to guide the airflow to the vent hole 104. Sealing sleeves 2022 are provided at the connection points between the interfaces at both ends of the medicine storage cylinder 202 and the air pipe 103 and the delivery pipe 303. The guide block 105 guides the airflow to the inner wall of the power unit 1, allowing it to be better discharged from the vent hole 104. When the connecting pipe 301 and the power unit 1 are connected to the storage unit 2, the delivery pipe 303 and the air pipe 103 are aligned with the interfaces at both ends of the medicine storage cylinder 202. Moving the sealing sleeves 2022 on both ends of the interfaces allows them to cover the connection points between the interfaces at both ends of the medicine storage cylinder 202 and the air pipe 103 and the delivery pipe 303, thereby reducing gaps, improving sealing, and preventing gas or liquid leakage.

[0020] In this embodiment, the filtration assembly includes a pre-filter 2011 and a post-filter 2012 mounted on a mounting frame 201. The pre-filter 2011 is made of medical-grade HEPA material, and the front section of the post-filter 2012 is cured with a disinfectant, while the rear section is filled with an activated carbon layer. The medical-grade HEPA material pre-filter 2011 effectively intercepts pubic hair and dander. The disinfectant cured in the front section of the post-filter 2012 is a solid quaternary ammonium salt polymer, which can effectively disinfect microorganisms in the gas. The disinfected gas then passes through the activated carbon layer in the rear section of the post-filter 2012 for adsorption and purification, eliminating odors, so that the gas finally discharged from the power unit 1 is odorless and free of chemical residues.

[0021] In this embodiment, the fixing frame 201 is provided with a number of inclined rods 2013, which are staggered and distributed on the inner wall of the storage section 2. They can hook the pubic hair that enters the storage section 2, so as to avoid a large amount of pubic hair from gathering on the filter component, affecting the breathability and causing the suction effect to deteriorate.

[0022] In this embodiment, the one-way valve includes a fixed shaft 2031 fixedly disposed within the storage section 2 and two sets of baffles 203 rotatably disposed on the fixed shaft 2031. A spring plate 2032 is disposed on the fixed shaft 2031. The spring plate 2032 is disengaged from the baffles 203, which is used to seal the baffles 203 at the interface of the storage section 2. When negative pressure suction is generated, the two sets of baffles 203 are driven by the suction to rotate around the fixed shaft 2031 and squeeze the spring plate 2032, thereby opening the interface of the storage section 2 and allowing pubic hair to enter. When the negative pressure stops, under the action of the spring plate 2032, the two sets of baffles 203 rotate back and close the interface of the storage section 2 again, achieving preliminary automatic sealing and preventing the leakage of pubic hair and dander stored inside the storage section 2, which would lead to environmental pollution.
