Description

Technical Field

[0001] This utility model relates to the field of flushing and suction technology, specifically a disposable flushing and suction device. Background Technology

[0002] This disposable rinsing device is specifically designed for feminine hygiene. It comes in sterile, individually packaged packaging and integrates gentle rinsing with safe suction. Its structure includes a reservoir pre-filled with saline or buffer solution, a low-flow nozzle, and an anti-backflow negative pressure device. By controlling the water flow intensity (typically ≤15kPa), it achieves gentle cleaning of the vaginal mucosa, avoiding the disruption of the vaginal microecology caused by traditional rinsing methods. The device uses medical-grade flexible materials (such as PP and TPE), and the contact surfaces are lubricated to reduce friction and irritation. The nozzle angle is ergonomically designed for precise coverage of the vulva and vaginal vestibule area.

[0003] Existing disposable irrigators can only rinse in one direction, making it difficult to thoroughly clean the edges of wounds or complex terrain. Lateral rinsing can lead to contaminant residue due to water flow dispersion. In addition, the lack of anti-contamination design can easily cause cross-infection. Furthermore, the lack of anti-slip structure in the press-type device often causes hand slippage, and uneven force may cause fluctuations in rinsing pressure, affecting the cleaning effect or causing damage. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a disposable flushing device, including a pressing head, the bottom of which is fixedly connected to an external threaded tube, and the surface of the external threaded tube is threadedly connected to a main body component.

[0005] The main component includes an internally threaded tube 1, a bottom flushing head is threadedly connected to the surface of the internally threaded tube 1, a water outlet is provided at the bottom of the bottom flushing head, an externally threaded tube 2 is fixedly connected to the bottom of the internally threaded tube 1, an internally threaded tube 2 is threadedly connected to the surface of the externally threaded tube 2, a side flushing head is fixedly connected to the bottom of the internally threaded tube 2, and a side flow port is provided on the surface of the side flushing head.

[0006] Through the above technical solution, the threaded connection between the external threaded tube at the bottom of the press head and the main component allows for quick disassembly and assembly, facilitating cleaning, disinfection, or replacement of parts, reducing the risk of cross-infection. The main component integrates a bottom rinsing head and a side rinsing head dual module, and through the water flow diversion design, it can simultaneously rinse and clean different areas, improving cleaning efficiency.

[0007] As a further improvement to the above solution, the second externally threaded pipe is concentric with the bottom flushing head, and the surface of the bottom flushing head is in contact with the surface of the side flushing head.

[0008] Through the above technical solution, the concentric layout of the external threaded tube and the bottom flushing head ensures that the water flow impacts the bottom of the wound vertically, reducing lateral fluid loss. The close contact between the bottom and the surface of the side flushing head forms a sealing barrier, preventing the flushing fluid from leaking and ensuring that the lateral water flow accurately covers the wound edge area, avoiding secondary contamination.

[0009] As a further improvement to the above scheme, the top of the internally threaded tube 2 is in contact with the bottom of the internally threaded tube 1.

[0010] Through the above technical solution, the end contact design between the internally threaded pipe II and the internally threaded pipe I shortens the fluid transmission path, reduces the friction loss along the pipeline, and strengthens the structural rigidity of the main components to prevent deformation or loosening during high-pressure flushing, thus ensuring flushing stability.

[0011] As a further improvement to the above solution, the output end of the externally threaded tube is located inside the pressing head.

[0012] The above technical solution optimizes the operator's hand position by embedding the output end of the external threaded tube into the pressing head. When pressing, the liquid is discharged directly through the hidden channel, avoiding the risk of liquid splashing or contamination caused by traditional exposed interfaces. At the same time, it simplifies the appearance of the device and improves the safety of use.

[0013] As a further improvement to the above solution, the materials of the pressing head, the bottom flushing head, and the side flushing head are medical-grade polyethylene.

[0014] The above technical solution uses medical-grade polyethylene material to make key components, which has the advantages of biocompatibility, chemical corrosion resistance and low cost, meets the hygiene requirements of single-use scenarios, and the material's flexibility can reduce the risk of mechanical damage to the cleaning area in case of misoperation.

[0015] As a further improvement to the above solution, the number of side outlets is set to several, and the several side outlets are distributed in a circumferential array on the top of the side flushing head, with the side outlets located below the water outlet.

[0016] Through the above technical solution, the circumferential array of side flow ports of the side rinsing head allows the lateral water flow to be evenly diffused. Combined with the bottom water outlet, it forms a progressive rinsing mode from bottom to top, which not only avoids damage to fragile tissues caused by high pressure direct spray, but also ensures thorough cleaning of the wound through multi-directional flow coverage.

[0017] As a further improvement to the above solution, a pressing plate is fixedly connected to the top of the pressing head, and an anti-slip groove is provided on the top of the pressing plate.

[0018] Through the above technical solution, the anti-slip groove on the top of the pressing plate increases the friction of the contact surface, which significantly improves the stability of operation. Especially in humid environments or when wearing gloves, it can still accurately control the pressing pressure and reduce the problem of interruption of rinsing or loss of pressure due to hand slippage.

[0019] As a further improvement to the above solution, the number of anti-slip grooves is set to several, and the several anti-slip grooves are evenly distributed on the surface symmetrically around the center of the top of the pressing plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention, by setting a bottom flushing head and a side flushing head, allows for direct cleaning of the cleaning area through the bottom flushing head, while the side flushing head connects the internally threaded pipe to the surface of the externally threaded pipe. When the flushing head is pressed, the cleaning fluid inside the flushing head enters the interior of the side flushing head through the water outlet, and then exits through the side outlet on the surface of the side flushing head. This enables cleaning of the surrounding area of ​​the cleaning area, increasing the practicality of the disposable flushing device.

[0022] This invention incorporates anti-slip grooves, which increase the frictional force of the fingers pressing the press head when it is pressed, thus preventing slippage during the pressing process. Attached Figure Description

Inside head 1, the inner threaded tube 31 is then threaded to the surface of the outer threaded tube 2. Pressing the outer threaded tube 2 causes the cleaning fluid to be discharged directly through the water outlet 33 at the bottom of the bottom flushing head 32, allowing direct rinsing of the cleaning area. The inner threaded tube 35 is then threaded to the surface of the outer threaded tube 34. When pressing head 1, the cleaning fluid inside pressing head 1 enters the interior of the side flushing head 36 through the water outlet 33, and then is discharged through the side outlet 37 on the surface of the side flushing head 36, allowing cleaning of the surrounding area of ​​the cleaning area.

[0033] The externally threaded pipe 34 is concentric with the bottom flushing head 32, and the surface of the bottom flushing head 32 is in contact with the surface of the side flushing head 36.
