TECHNICAL FIELD

[0001] The utility model belongs to waste liquid treatment technical field, especially related to a continuous blood purification waste liquid treatment and discharge device. BACKGROUND

[0002] Continuous renal replacement therapy (CRRT) is an important treatment method for critically ill patients, and its core is to maintain the vital signs of patients through continuous blood purification process. However, the waste liquid treatment generated in the CRRT process has always been a problem to be solved. The traditional CRRT waste liquid treatment method usually directly pours the waste liquid into the sewage pool or toilet bowl. Although this method is simple, it has many pollution risks.

[0003] Firstly, the CRRT waste liquid may contain a large amount of pathogens, drug residues and other harmful substances. If these substances are not properly treated, they may cause serious pollution to medical personnel and the environment. The traditional pouring method lacks effective splash-proof measures. In the moment of opening the waste liquid bag or cutting the bag opening, the waste liquid is easy to splash, causing uncontrollable pollution risk. In addition, the odor and pollutants generated during the waste liquid pouring process may also have a negative impact on the medical environment. In view of these problems, a new type of continuous blood purification waste liquid treatment and discharge device is proposed. SUMMARY

[0004] The utility model provides a continuous blood purification waste liquid treatment and discharge device in view of the deficiency of prior art, and the specific technical scheme is as follows:

[0005] The utility model provides a continuous blood purification waste liquid treatment and discharge device, including the mobile seat of the handling pool is supported, can move in time according to actual needs, the splash-proof slope of low in front high in back is set up in the handling pool, its bottom is connected with the waste pipe of exhaust and is equipped, is used for the discharge of CRRT waste liquid, the upper edge of handling pool is provided with the dirt-proof cover that can be buckled, its opposite handling pool's one side is provided with the lower pressure buckle of the triangular section and is extended and is equipped with the dirt-proof fence of the inboard of both ends to it, can avoid the splash of waste liquid with the lower pressure buckling of dirt-proof cover, the bottom wall of handling pool is embedded with a plurality of upper cutters corresponding with lower pressure buckle, its upper edge is provided with the blade edge, can complete the discharge of waste liquid with the lower extrusion of dirt-proof cover waste liquid bag.

[0006] As a preferred technical scheme of the utility model, the dirt-proof cover is connected with the handling pool through the hinge, and a plurality of downward extending flexible extrusion cones are uniformly arranged on the inner side of the lower pressure buckle of the dirt-proof cover, which realizes directional extrusion and blasting in cooperation with the upper cutter, and is used for harmless treatment of waste liquid bag breaking.

[0007] As an optimal technical scheme of the utility model, the upper cutter includes a rotatable turntable embedded in the inner wall of the treatment pool, and two pairs of opposite shunt knives are staggered on the turntable, which can rotatably guide the flow direction of waste liquid and efficiently guide the waste liquid.

[0008] As an optimal technical scheme of the utility model, the treatment pool is connected with the waste discharge pipe and is provided with a detachable slow-release net on the cover, which is a hollow structure screen and is provided with a plurality of filter holes, can guide the discharge of waste liquid and intercept the waste liquid bag, and is used for instant collection of the waste liquid bag.

[0009] As an optimal technical scheme of the utility model, the waste discharge pipe is an h-shaped structure, and a bend is arranged in the waste discharge pipe, which can avoid that the flow of waste liquid is too large and overflows the treatment pool.

[0010] As an optimal technical scheme of the utility model, the material of the treatment pool is 304 stainless steel, and the material of the anti-fog cover is transparent PVC, which can be pressed to instantly view the treatment of waste liquid.

[0011] The utility model has the advantages of:

[0012] 1. effectively prevent waste liquid from splashing, and reduce the pollution risk: in the traditional CRRT waste liquid treatment mode, splashing is easy to occur when the waste liquid is poured or the bag opening is cut, which causes medical staff to contact the waste liquid containing pathogenic bacteria and harmful substances, and there is a serious pollution and infection risk. The device can effectively inhibit the splashing of waste liquid through the cooperative design of the anti-splashing slope, the anti-pollution cover and the pressing buckle. The front-low and rear-high design of the anti-splashing slope can guide the stable flow of waste liquid, and the buckling of the anti-pollution cover and the mechanical extrusion of the pressing buckle ensure that the waste liquid bag will not accidentally splash when being treated. This design greatly reduces the infection risk of medical staff, and also avoids the pollution of waste liquid to the environment.

[0013] 2. improve the treatment efficiency and reduce the secondary pollution: the traditional treatment mode needs manual opening of the waste liquid bag or pouring of the waste liquid, and the operation process is not only low in efficiency, but also may cause secondary pollution due to improper operation. The device can automatically complete the extrusion and discharge of waste liquid through the mechanical design. The upper cutter embedded in the bottom wall of the treatment pool cooperates with the pressing buckle of the anti-pollution cover to quickly and efficiently complete the discharge of waste liquid, reduce the time and frequency of manual operation. At the same time, the mobility of the treatment pool makes it can be flexibly deployed according to the actual demand, which further improves the treatment efficiency.

[0014] 3. Reduce the pollution of medical waste liquid to the environment: CRRT waste liquid contains harmful substances such as drug residues and pathogens. The traditional dumping method may cause these substances to enter the sewage system or the environment, causing secondary pollution. However, the device is designed with a pollution-proof cover and a pollution-proof fence to ensure that the waste liquid does not leak or splash during the treatment process, better controlling the flow of waste liquid and reducing pollution to the environment. At the same time, the waste pipe of the device directly guides the waste liquid to the designated discharge channel, avoiding the possibility of waste liquid spreading to non-treatment areas.

[0015] 4. Improve the medical environment and protect the health of medical staff: In the traditional treatment method, the waste liquid may produce odors or pollutants when it is poured, which may have a negative impact on the medical environment and the health of medical staff. However, the device is designed with a pollution-proof cover and a pollution-proof fence to effectively isolate the waste liquid and odors, reducing the impact on the medical environment. In addition, the mechanical operation of the device reduces the direct contact of medical staff with waste liquid, further protecting the health of medical staff.

[0016] 5. Save resources and reduce processing costs: The design of the device has high versatility and flexibility, and the treatment pool can be moved and deployed according to actual needs to adapt to different usage requirements. At the same time, the mechanical design of the device reduces the need for manual operation, reducing labor costs. The reusable and cleanable design of the treatment pool also reduces the use of disposable consumables, further reducing processing costs.

[0017] In summary, the continuous blood purification waste liquid treatment and discharge device effectively solves the pollution problem in the treatment of CRRT waste liquid through its innovative mechanical design. It not only reduces the risk of infection for medical personnel, but also reduces the pollution of medical waste liquid to the environment, improving processing efficiency and safety. At the same time, its flexibility and economy make it an ideal choice for medical institutions to treat CRRT waste liquid, providing a more efficient and environmentally friendly solution for medical waste management.
