Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a drainage and anti-backflow waste discharge device for hemodialysis rooms. Background Art

[0002] Hemodialysis is one of the kidney replacement treatment methods for patients with acute and chronic renal failure. The sewage generated during hemodialysis is discharged into a dedicated sewer through a drain pipe. However, liquid is likely to overflow at the drain outlet, polluting the surrounding environment. Moreover, bacteria and microorganisms existing in the drain pipe can enter the drain pipe through the bottom end of the drain pipe, affecting the hygiene of the drain pipe.

[0003] In the prior art, a Chinese patent with the publication number of CN208785414U discloses a drainage isolator for a dialysis machine, which is installed between the drain pipe of the dialysis machine and the sewer. It has a funnel and a fixing seat. The funnel is installed below the end of the drain pipe outlet, and the fixing seat is installed at the inlet of the sewer. The funnel and the fixing seat are detachably connected; the floating ball is a table tennis ball; the fixing seat includes a universal joint and a fixing wing. The inner pipe of the universal joint is inserted into the sewer, and a fixing wing is arranged at the lower end of the outer part of the universal joint. The fixing wing is placed around the water inlet of the sewer. The utility model is installed between the end of the dialysis machine catheter and the drain outlet, is transparent and visible, and has functions of anti-splash blocking, air anti-pollution blocking and odor blocking, so that the drain pipe of the dialysis machine is not directly connected to the drain pipe, and there is an air separation between them, avoiding the upward pollution of bacteria along the drain pipe and the sewer pipe.

[0004] When the patent is actually used, the following defects exist: in the patent, only a table tennis ball is used for plugging, so the sealing performance is insufficient. Because the weight of the table tennis ball is light, slight vibration can cause the table tennis ball to displace, so there will be a situation of back leakage, and the bottom of the funnel cannot be effectively plugged. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a drainage and anti-backflow waste discharge device for hemodialysis rooms.

[0006] To achieve the above object, the utility model provides the following technical solution: a drainage and anti-backflow waste discharge device for hemodialysis rooms, including an end cover. A connecting ring is arranged at the bottom of the end cover. A drainage funnel is detachably connected to the bottom of the connecting ring. A sealing groove is arranged in the drainage funnel. A sealing block is arranged in the sealing groove. A connecting rod is fixedly connected to the outside of the sealing block. The connecting rod is fixedly connected to the top cover. A corrugated sleeve is fixedly connected between the connecting ring and the top cover. An adsorption assembly is arranged between the connecting ring and the end cover.

[0007] By adopting the above technical solution, when drainage is required, simply pull down the connecting ring, which drives the drainage hopper to move downward, causing the sealing block to move away from the sealing groove, thereby achieving drainage. After drainage is completed, move the connecting ring upward, and then let the sealing block be clamped in the sealing groove to achieve sealing, avoiding the backflow of waste water and bacteria. Moreover, the entire process is convenient and fast for manual operation. In addition, by pulling the operating connecting ring, the sealing block can be firmly clamped with the sealing groove.

[0008] In a further setting of the present utility model, a filter cartridge is fixedly connected to the top of the end cover, and the end cover communicates with the inside of the filter cartridge, and a filter element is fixedly connected inside the filter cartridge.

[0009] By adopting the above technical solution, harmful substances are filtered through the filter element, and the filter element can adopt microporous membranes, ultrafiltration membranes, nanofiltration membranes, etc.

[0010] In a further setting of the present utility model, a fixing ring is fixedly connected to the outside of the end cover.

[0011] By adopting the above technical solution, the fixing ring is used to install the adsorption component.

[0012] In a further setting of the present utility model, the adsorption component includes a first magnet ring fixedly connected to the top of the fixing ring, a second magnet ring fixedly connected to the bottom of the fixing ring, and an iron ring fixedly connected to the outside of the connecting ring.

[0013] By adopting the above technical solution, when discharging waste water, pull down the connecting ring. Since the connecting ring and the top cover are connected by a corrugated sleeve, the connecting ring can be smoothly pulled down, causing the iron ring to no longer adsorb to the first magnet ring and adsorb to the second magnet ring below at the same time. After draining, push the connecting ring upward to make the sealing block be clamped and sealed in the sealing groove again. At this time, the iron ring adsorbs and fixes to the first magnet ring again. Therefore, through the sealing cooperation between the sealing block and the sealing groove, the backflow of waste water and bacteria can be avoided.

[0014] In a further setting of the present utility model, a rubber sleeve is sleeved on the outside of the sealing block, and the sealing groove fits with the outside of the sealing block.

[0015] By adopting the above technical solution, the sealing performance can be improved.

[0016] In a further setting of the present utility model, the sealing block is spherical, square or conical.

[0017] By adopting the above technical solution, the sealing block in the present utility model is spherical.

[0018] In a further setting of the present utility model, the corrugated sleeve can also be replaced by a rubber sleeve.

[0019] By adopting the above technical solutions, the pulling operation of the connecting ring can be realized.

[0020] The beneficial effects of the present utility model are as follows: Compared with the prior art, in the present utility model, when draining water, only need to pull the connecting ring downward, so that the connecting ring drives the drain hopper to move downward, thereby making the sealing block away from the sealing groove, so as to realize drainage. Then, after draining, move the connecting ring upward, and then make the sealing block snap into the sealing groove to realize sealing, avoiding the back-seepage of waste water and bacteria. Moreover, the whole process is convenient and fast for manual operation. In addition, by pulling the connecting ring, the sealing block can be firmly snapped into the sealing groove.

A connecting rod 6 is fixedly connected to the outside of the sealing block 5. The connecting rod 6 is fixedly connected to the top cover 7. The sealing block 5 is used to seal the sealing groove 13 to prevent the backflow of waste water and bacteria. And through the resistance of the connecting rod 6, the sealing block 5 can be firmly clamped in the sealing groove 13. A corrugated sleeve 12 is fixedly connected between the connecting ring 4 and the top cover 7. The corrugated sleeve 12 can also be replaced by a rubber sleeve. The function of the corrugated sleeve 12 is to facilitate the telescopic adjustment of the connecting ring 4 and the drainage hopper 3 when pulling the connecting ring 4.
