Description

[Technical field]

[0001] The invention relates to the technical field of medical instruments, and in particular to a filter for filtering foreign matter in urine. [Background technology]

[0002] At present, when using external urine collectors (negative pressure drainage devices) on the market, when urine containing foreign matter is discharged into the catheter, the foreign matter in the urine, such as shredded paper towels, fluff, hair, and stone particles, will block the catheter or urine pump, and the urine cannot be discharged in time, causing urine leakage and overflow, increasing the burden of nursing and causing discomfort to the patient. It will cause the patient's lower body skin to become red and even rotten, increasing the patient's pain and causing trouble for nursing work, especially increasing the difficulty of patient recovery. [Summary of the invention]

[0003] The utility model aims to solve the above problems and provides a filter with a simple structure for filtering foreign matter in urine.

[0004] To achieve the above purpose, the utility model provides a filter, which includes a filter box, a sealing gasket, a filter screen and a filter box cover plate, the filter screen and the filter box cover plate form a certain angle, and the filter screen is located in the filter box.

[0005] The filter box includes a filter box body, a fixed end and a pagoda joint. The filter box body is a rectangular parallelepiped, a cube or an irregular body with one side open. The fixed end is provided with a slot. One end of the pagoda joint is a urine inlet port, and the other end is a urine discharge port.

[0006] The fixed end is provided with a fixing cap, a buckle is arranged inside the fixing cap, and the buckle matches with a slot on the filter box.

[0007] The filter screen is a thin flat plate with round holes, and the diameter of the round holes is 0.2-0.6CM.

[0008] The filter box cover plate is a transparent panel.

[0009] The filter also includes screws and nuts.

[0010] Compared with the prior art, the filter structure of the utility model has the following beneficial effects: in the utility model, urine containing foreign matter flows into the filter box, and the urine can be discharged smoothly through the filter net. Foreign matter in the urine, such as shredded paper towels, fluff, hair, stone particles, etc., is filtered in the box. Through the transparent cover, the foreign matter inside and the color of urine during urination can be observed, which is convenient for nursing staff to understand the patient's physical condition in time and disassemble and clean it by themselves. It avoids host failure caused by blockage, reduces maintenance costs, improves usage efficiency, and at the same time observes whether the urine color is normal to seek medical help.

Brief Description of the Drawings

[0011] Figure 1 It is an exploded view of the utility model.

[0012] Figure 2 It is an exploded plan view of the utility model. [Specific implementation method]

[0013] The following examples are provided to further explain and illustrate the present invention and do not constitute any limitation to the present invention.

[0014] like Figure 1 , Figure 2 As shown, a filter of the utility model includes a filter box 1, a sealing gasket 2, a filter screen 3 and a filter box cover plate 4. The filter screen 3 can be perpendicular to the filter box cover plate 4, or the filter screen 3 can also be not perpendicular to the filter cover plate 4, and is designed to have a certain tilt angle, which is greater than 30 degrees. The filter screen 3 and the filter cover plate 4 can be split designs or integrally formed. In this embodiment, the filter screen 3 and the filter cover plate 4 are integrally formed, and the filter screen 3 is perpendicular to the filter box cover plate 4. The filter screen 3 is located in the filter box 1. The sealing gasket 2 is located between the filter box 1 and the filter box cover plate 4 to avoid leakage and seepage during urination.

[0015] like Figure 1 , Figure 2 As shown, the filter box 1 includes a filter box body 11, a fixed end 12 and a pagoda joint 13. The filter box body 11 is a rectangular parallelepiped or a cube or an irregular body with an open side, and is used to temporarily store foreign matter such as shredded paper towels, fluff, hair, stone particles, etc. after filtering. The fixed end 12 is provided with a card slot 121, and one end of the pagoda joint 13 close to the filter screen 3 is a urination port, and the other end is a urine inlet port. The fixed end 12 is installed with a fixing cap 5, and a buckle 51 is provided in the fixing cap 5. The buckle 51 cooperates with the card slot 121 provided on the fixed end 12. In this embodiment, the fixed end 12 and the fixing cap 5 are connected by a buckle, and can also be threaded.

[0016] like Figure 1 , Figure 2 As shown, the filter screen 3 is a thin flat plate with a plurality of small round holes with a diameter of 0.2-0.6CM, which can filter most of the foreign matter such as shredded paper towels, fluff, hair, stone particles, etc. The shape of the thin flat plate of the filter screen 3 corresponds to the internal structure of the filter box body 11. The filter box cover 4 is a transparent panel, which can be used to observe the filtered foreign matter in the filter box, facilitate cleaning and washing, ensure the normal operation of the urinator, and observe whether the urine color is normal during urination to pay attention to the patient's physical condition.

[0017] like Figure 1 , Figure 2 As shown, the filter also includes screws 6 and nuts 7, which play a role in fastening the filter.

[0018] In the utility model, urine containing foreign matter flows into the filter box body, and the urine can be discharged smoothly through the filter net. Foreign matter in the urine, such as shredded paper towels, fluff, hair, stone particles, etc., is filtered in the box body. Through the transparent cover, the foreign matter inside and the color of urine during urination can be observed, which is convenient for nursing staff to understand the patient's physical condition in time and disassemble and clean it by themselves. It avoids host failure caused by blockage, reduces maintenance costs, improves usage efficiency, and at the same time observes whether the urine color is normal to seek medical help.

[0019] Although the present invention is disclosed through the above embodiments, the protection scope of the present invention is not limited thereto. Without departing from the concept of the present invention, any deformation, replacement, etc. made to the above components shall fall within the scope of the claims of the present invention.
