Description

Technical Field

[0001] This application relates to the field of medical waste liquid treatment equipment technology, and in particular to a medical waste liquid collection and treatment device. Background Technology

[0002] Medical institutions generate large amounts of medical waste fluids during routine diagnosis, surgery, and laboratory tests. These waste fluids are complex in composition, often containing pathogens, toxic chemicals, heavy metals, and radioactive substances, posing direct or indirect infectiousness and hazards. Therefore, the safe and effective collection and treatment of medical waste fluids is a crucial step in controlling hospital infections, protecting the environment, and safeguarding personnel health.

[0003] In the collection of medical waste fluids, a necessary step is to connect the treatment device to the source of the waste fluid (such as diagnostic equipment or drainage pipes). This connection process requires quick and easy operation, and must ensure an absolutely secure and sealed connection to prevent leakage of hazardous waste fluids during collection or transportation.

[0004] However, existing medical waste collection devices often have shortcomings in the design of their connecting pipe structures. Some devices use traditional threaded tightening or flange bolt fixing methods, which, while providing a certain degree of sealing, are cumbersome and time-consuming, making them inefficient in situations requiring frequent connections or emergency handling. Other devices employ simple snap-fit ​​or plug-in structures to prioritize connection speed, but these structures often lack stability and are prone to loosening or detachment under accidental pulling or vibration, causing seal failure and potentially leading to dangerous waste leakage accidents, posing significant safety hazards to operators and the environment.

[0005] Therefore, existing technical solutions cannot simultaneously balance the convenience of connection operation and the reliability of connection status, and have core problems such as low operational efficiency and high leakage risk due to unreasonable connection structure.

[0006] Therefore, this utility model proposes a medical waste liquid collection and treatment device to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the medical waste liquid collection and treatment device, such as inconvenient connection operation when connecting to external connecting pipes, low reliability, easy leakage, incomplete waste liquid treatment process and poor purification effect, this utility model aims to provide a medical waste liquid collection and treatment device with improved structure that can effectively solve the above problems.

[0008] This application provides a medical waste liquid collection and treatment device with the following technical solution: a base plate; and a purification mechanism fixedly connected to the top of the base plate. The purification mechanism includes a second storage tank fixedly connected to the top left side of the base plate, a first storage tank fixedly connected to the top right side of the base plate, a support plate fixedly connected to the base plate, and a motor, a slow-release sterilizer, and a filter adsorption device fixedly connected to the support plate. The device also includes a fixing mechanism; Through the above technical solution: medical waste liquid is first collected into storage tank two, and under the coordination of the control device, it is transported by motor to the slow-release sterilizer for preliminary disinfection, and then treated by the filtration and adsorption device before entering storage tank one. The control device ensures full treatment throughout the process; the fixing mechanism achieves convenient and stable connection between the pipeline and storage tank two through the cooperation of components such as nuts and rotating rings.

[0009] Preferably, the fixing mechanism includes a fixing tube fixedly connected to the bottom right side of the storage tank, a connecting ring sleeved on the outside of the fixing tube, a rotating ring rotatably sleeved on the outside of the connecting ring, a limiting block slidably disposed on the inner wall of the connecting ring, and a connecting rod, a guide rod and a nut. By adopting the above technical solution, the fixing of the rotating ring and connecting ring is released by rotating the nut. Rotating the rotating ring pushes the limiting block into the fixed pipe under the guidance of the guide rod, completing the initial fixing. Then, rotating the nut fixes the position of the rotating ring and the connecting ring, so that the limiting block is continuously supported and restricted, thereby realizing the connection ring driving the pipeline to be conveniently fixed on the fixed pipe. Among them, the fixed pipe, connecting ring, rotating ring, limiting block, connecting rod, guide rod and nut cooperate with each other to ensure the stability of the connection.

[0010] Preferably, the inlet end of the motor is connected to the second storage tank, the inlet end of the slow-release sterilizer is connected to the outlet end of the motor, the inlet end of the filter adsorption device is connected to the outlet end of the slow-release sterilizer, and the outlet end of the filter adsorption device is connected to the first storage tank. The purification mechanism also includes a bracket and a control device. The bracket is fixedly connected to the support plate, and the control device is fixedly connected to the front top of the bracket and electrically connected to the motor. By adopting the above technical solution, in the purification unit, medical waste liquid is transported from storage tank two to the slow-release sterilizer by motor, and then flows through the filtration and adsorption device before entering storage tank one; the control device fixed on the support plate bracket is electrically connected to the motor, and by controlling the operation of the motor, it coordinates the various components to complete the orderly treatment of waste liquid, ensuring that the treatment process is stable and efficient.

[0011] Preferably, the control device is used to monitor the liquid level in the storage tank 2, and control the motor to start when the liquid level reaches a preset value; By adopting the above technical solution, the core function of the control device is to monitor the liquid level in storage tank 2. When the liquid level reaches the preset value, the motor will be automatically started. This will push the medical waste liquid from storage tank 2 into the slow-release sterilizer and the filter adsorption device in sequence, and finally into storage tank 1, so as to realize the automatic triggering and orderly operation of the waste liquid treatment process.

[0012] Preferably, one end of the connecting rod is rotatably connected to the inner wall of the rotating ring via a rotating shaft, and the other end of the connecting rod is rotatably connected to the limiting block via a connecting shaft; By adopting the above technical solution, one end of the connecting rod is rotatably connected to the inner wall of the rotating ring via a rotating shaft, and the other end is rotatably connected to the limiting block via a connecting shaft. When the rotating ring rotates, the connecting rod will move in conjunction with it, and the limiting block will be moved by means of the rotating connection structure at both ends, thereby realizing the locking or unlocking of the limiting block on the fixed tube, and providing transmission support for the fixing function of the fixing mechanism.

[0013] Preferably, a limiting ring groove is formed on the outer wall of the fixing tube, and one end of the limiting block is adapted to be inserted into the limiting ring groove; one end of the guide rod is fixedly connected to the inner wall of the connecting ring, and the other end of the guide rod is fixedly connected to the limiting block; By adopting the above technical solution, the limiting ring groove opened on the outer wall of the fixed pipe provides a suitable locking space for the limiting block. When one end of the limiting block is locked into the limiting ring groove, the initial positioning of the fixed pipe and the connecting ring can be achieved. One end of the guide rod is fixed to the inner wall of the connecting ring and the other end is fixed to the limiting block, which not only provides stable guidance for the movement of the limiting block, but also provides support for the limiting block, ensuring that the limiting block remains stable during the locking process, and ultimately helping the fixing mechanism to achieve a stable connection between the pipeline and the fixed pipe.

[0014] Preferably, the bottom end of the nut is externally threaded to the outer inner wall of the connecting ring, and the inner wall of the rotating ring is threaded to the nut. The nut is used to fix the relative position of the rotating ring and the connecting ring. By adopting the above technical solution, the nut can effectively fix the relative position of the rotating ring and the connecting ring by means of the double threaded connection between the bottom end and the outer inner wall of the connecting ring, and between the inner wall and the rotating ring. This fixation can maintain the locking state of the limiting block on the fixed pipe, thereby ensuring the stable connection of the fixing mechanism and providing a key guarantee for the solid connection between the pipe and the fixed pipe.

[0015] Preferably, a sealing gasket is fixedly connected to the outer periphery of the fixing tube, and the inner wall of the connecting ring is sealed and fitted with the sealing gasket; By adopting the above technical solution, the sealing gasket fixed to the outer periphery of the fixed tube can achieve a sealed fit with the inner wall of the connecting ring. This design can effectively block the gap at the connection between the fixed tube and the connecting ring. Through the sealing effect of the sealing gasket, the medical waste liquid transported in the pipeline can be prevented from leaking from the connection. While the fixed mechanism achieves a stable connection of the pipeline, it also provides an additional reliable sealing guarantee, ensuring the sealing and safety of the waste liquid treatment process.

[0016] Preferably, the device further includes a connecting pipe, one end of which is fixedly connected to the connecting ring; By adopting the above technical solution, one end of the connecting pipe in the device is fixedly connected to the connecting ring. With the help of the stable connection between the connecting ring and the fixed pipe, the connecting pipe can form a complete fluid channel with the fixed pipe. This connection method allows medical waste liquid to be smoothly transported from the storage tank through the fixed pipe and the connecting pipe to the subsequent processing components. At the same time, with the sealing effect of the sealing gasket, the continuity of waste liquid transportation is ensured and leakage problems are avoided during transportation, providing channel support for the smooth operation of the entire waste liquid treatment process.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model solves the problems of incomplete medical waste liquid treatment process, poor purification effect and low degree of automation in the prior art by setting up a purification mechanism consisting of storage tank two, motor, slow release sterilizer, filter adsorption device and storage tank one, and realizing automatic operation by control device. It achieves the technical effect of multi-stage deep purification of medical waste liquid such as disinfection, filtration and adsorption, effectively reducing the harm of waste liquid, realizing automatic treatment and improving work efficiency.

[0018] 2. This utility model, by setting up a fixing mechanism composed of components such as a fixed tube, connecting ring, rotating ring, connecting rod, limiting block and nut, uses rotation to drive multiple limiting blocks to achieve radial locking, which solves the problems of complex, time-consuming and labor-intensive connection operation and poor connection reliability of the connecting tube in the prior art, and achieves the technical effect of quickly and conveniently fixing the external connecting tube, and the connection is stable and not easy to loosen.

[0019] 3. This utility model solves the problem of insufficient sealing at the connection of the connecting pipe in the prior art, which easily leads to leakage of harmful waste liquid and poses safety hazards, by setting a sealing gasket at the connection of the fixing mechanism and using the structure of the rotating ring driving the limit block to clamp and the nut to lock, thereby applying a stable clamping force to the connection.

One end of the guide rod 36 is fixedly connected to the inner wall of the connecting ring 32, and the other end of the guide rod 36 is fixedly connected to the limiting block 38. The bottom end of the nut 39 is externally threaded to the outer inner wall of the connecting ring 32, and the inner wall of the rotating ring 33 is threadedly connected to the nut 39.

The device also includes a connecting tube 302, one end of which is fixedly connected to the connecting ring 32.

[0028] In a preferred embodiment, the inlet end of the motor 22 is connected to the bottom of the storage tank 27 via a pipe, the inlet end of the slow-release sterilizer 28 is connected to the outlet end of the motor 22 via a pipe, the inlet end of the filter adsorption device 25 is connected to the outlet end of the slow-release sterilizer 28 via a pipe, and the outlet end of the filter adsorption device 25 is connected to the top of the storage tank 26 via a pipe.

[0029] In a preferred embodiment, the control device 24 is equipped with a liquid level sensor, the probe of which extends into the storage tank 27. The control device 24 also includes a microprocessor electrically connected to the liquid level sensor and the motor 22.

[0030] As a preferred connection structure, the inner wall of the rotating ring 33 is evenly distributed with a plurality of connecting rods 35 that are rotatably connected by a rotating shaft 34. Correspondingly, the inner wall of the connecting ring 32 is evenly distributed with a plurality of limiting blocks 38 and guide rods 36. Each connecting rod 35 is rotatably connected to a limiting block 38 through a connecting shaft 37.

[0031] As a preferred guide structure, one end of the guide rod 36 is fixedly connected to the opposite side of the limiting block 38, and the other end of the guide rod 36 is fixedly connected to the inner wall of the connecting ring 32. The guide rod 36 is used to provide radial guidance when the limiting block 38 moves.

[0032] As a preferred locking method, the nut 39 has a double-threaded structure, with its external thread connected to the inner wall of the rotating ring 33, and its internal thread connected to the external thread on the outer inner wall of the connecting ring 32.

[0033] As a preferred sealing solution, two annular grooves are provided on the outer periphery of the fixing tube 31, and two sealing gaskets 301 are respectively embedded in the corresponding annular grooves. When the connecting ring 32 is sleeved, its inner wall is tightly pressed against the outer surface of the two sealing gaskets 301.

[0034] The implementation principle of this embodiment is as follows: A purification mechanism 2 is fixedly connected to the top of the base plate 1. The storage tank 27 in the purification mechanism 2 is fixed to the top left side of the base plate 1. The waste liquid first flows into the storage tank 27 fixed to the top left side of the base plate 1, where it temporarily collects the medical waste liquid. As the waste liquid accumulates in the storage tank 27, when the preset collection volume is reached, the control device 24 fixed to the front of the top of the support 23 accurately captures this signal and immediately issues an instruction to coordinate the start-up of each component. At this time, the motor 22 fixedly connected to the top left side of the support plate 21 starts to operate under the action of the control device 24. With its own power, it transports a certain amount of medical waste liquid collected in the storage tank 27 to the slow-release sterilizer 28, which is also fixed to the top of the support plate 21. The medical waste liquid undergoes preliminary disinfection treatment in the slow-release sterilizer 28, effectively killing some harmful microorganisms contained in the waste liquid and reducing its harmfulness. After initial disinfection, the medical waste liquid continues to flow to the filtration and adsorption device 25 fixed to the top right of the support plate 21. Under the action of the filtration and adsorption device 25, impurities in the waste liquid are effectively filtered and removed, and harmful chemicals contained in the waste liquid are also adsorbed, further improving the purification level of the waste liquid. After completing the filtration and adsorption treatment, the medical waste liquid will finally flow into the storage tank 26 fixed to the top right of the base plate 1 for temporary storage.

[0035] The bottom right side of storage tank 27 is fixedly connected to the fixing tube 31 of the fixing mechanism 3. When it is necessary to fix the connecting tube 302 to the fixing tube 31 at the bottom right side of storage tank 27, it is first necessary to release the two nuts 39 from the fixing of the rotating ring 33 and the connecting ring 32. Since the bottom of the nut 39 is threaded to the outer inner wall of the connecting ring 32, and the inner wall of the rotating ring 33 is threaded to the nut 39, loosening and unscrewing the nut 39 will release the locking state between the rotating ring 33 and the connecting ring 32. Subsequently, rotating the rotating ring 33 sleeved on the outside of the connecting ring 32 will cause the connecting rod 35 connected to the inner wall of the rotating ring 33 by multiple rotating shafts 34 to change angle as it rotates. Rotating ring 33 rotates and pushes connecting rod 35 to slide along the inner wall of connecting ring 32, pushing multiple limiting blocks 38 to move towards the inner wall of the limiting ring groove of fixed tube 31 under the guidance of connecting rod 36, until the near side of multiple limiting blocks 38 is precisely locked into the limiting ring groove of fixed tube 31, completing the initial fixation. When replacement is needed, rotating ring 33 in the opposite direction will cause rotating ring 33 to drive connecting rod 35 to rotate around the inner wall of connecting ring 32 as the fulcrum, causing the limiting blocks 38 to move away from the inner wall of 31 under the action of connecting rod 36, thus releasing fixed tube 31.

[0036] At this point, the connecting pipe 302 has achieved initial docking through the connection of its left side to the right side of the fixed pipe 31 and the fixation of its right side to the connecting ring 32. The two sealing gaskets 301 on the outside of the fixed pipe 31 are tightly fitted against the inner wall of the connecting ring 32, ensuring a tight seal at the connection. Finally, the two nuts 39 are rotated in the opposite direction to re-thread them between the inner wall of the rotating ring 33 and the outer inner wall of the connecting ring 32, fixing the relative position of the rotating ring 33 and the connecting ring 32. This, in turn, continuously applies an inward supporting force to the limiting block 38 through the connecting rod 35, ensuring that the limiting block 38 is stably engaged in the limiting ring groove of the fixed pipe 31. Ultimately, this achieves the effect of the connecting ring 32 driving the connecting pipe 302 to be conveniently and securely fixed to the right side of the fixed pipe 31.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
