Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a waste collection device and a waste liquid collection and treatment system. Background Art

[0002] During certain surgical procedures, liquid, semi-solid and solid wastes are inevitably generated, such as human body fluids such as blood, perfusion solutions introduced into the surgical site during the operation, human tissue fragments, small pieces of surgical materials, and other solid and semi-solid wastes generated during the operation. These wastes need to be collected in a timely manner to avoid contaminating the surgical site and becoming biohazardous materials in the operating room or other places where the surgical procedure is performed. In the prior art, a vacuum source is usually used to generate suction force to suck the waste generated at the surgical site into a specific collection container. That is, after the system is started, the suction force generated by the vacuum source reaches the surgical site, thereby sucking the waste into a specific collection container through the pipeline in contact with the surgical site.

[0003] In a medical waste collection and treatment system, waste materials are collected in a waste collection container connected to a vacuum source. The waste collection container is generally mounted on a portable trolley with wheels for easy movement and transportation. Generally speaking, during the suction process, when the storage volume of the waste collection container reaches a predetermined volume, the waste collection container needs to be emptied. The early prior art practice is to push the waste collection device to a docking station and empty and clean it. After the waste collection unit is docked to the docking station, it begins to be emptied. Once emptied, the waste collection container is cleaned by a cleaning system through disinfection and cleaning. In a series of medical processes, each process needs to be emptied. The frequent operation of pushing the waste collection device to the docking station each time brings a lot of inconvenience to the user and affects the progress of medical treatment. Therefore, in response to this technical defect, a transfer equipment has been developed that is specifically used to transport waste from a waste collection device to a docking station, that is, a docking equipment that is specifically used to transport waste from a waste collection device. The equipment usually includes two connectors that dock with two connectors of the waste collection device to form a liquid circuit connection, one liquid circuit is used to transfer the waste from the waste collection device to the docking equipment, and the other liquid circuit is used to clean the waste collection container of the waste collection device.

[0004] In an example of a prior art system, a docking device generally includes two connectors and two connectors of a waste collection device. The main method of automatic docking is to roughly match the positions of the docking device and the waste collection device first. When the two are roughly connected, the two connectors at the end of the docking device are moved in up, down, front, back, left, and right directions at most by an actuable component at the end of the docking device to align the two connectors of the docking device with the two connectors of the waste collection device. Since the connectors in the prior art can only be moved in up, down, front, back, left, and right directions at most, the correction directions can only be up, down, left, and right directions. After being aligned up, down, left, and right, the connectors of the docking device can be inserted by moving forward and backward. In the prior art, the structure for realizing the six-direction movement of the docking device end connector requires a bracket that can move in four directions. This bracket requires multiple elastic components and multiple structural components to realize it, and a stepper motor is used to realize the movement in the other two directions. The structure is complex and the equipment cost is high. In addition, the docking device and the waste collection device must be very accurately aligned before the connector can be inserted. That is, the docking heads of the docking device and the waste collection device need to be aligned before contact in order to perform the plug-to-socket operation, and the plug cannot continue to align after contacting the socket. This structure not only makes the alignment operation complicated, but also increases the complexity and cost of the equipment. At the same time, due to the low fault tolerance, under the premise of misalignment, the two connectors of the docking device and the two connectors of the waste collection device will cause damage to the connector when they are docked. Summary of the invention

When the suspension joint 167 is not connected to the collection end joint 165, the suspension joint 167 is in the initial position; in the process of connecting the docking end joint, the suspension joint 167 can be suspended and moved relative to the trolley joint fixing plate 163 and guide the docking end joint and the collection end joint 165 to align and connect accordingly. Specifically in this embodiment, there can be two collecting end joints 165 and two butt end joints, one of the collecting end joints 165 is used to discharge the waste in the waste collection container, and the other collecting end joint 165 is used to introduce cleaning liquid for cleaning the waste collection container. The two collecting end joints 165 and the two butt end joints are connected one by one. Correspondingly, there are also two floating joints 167, which respectively guide the two butt end joints to connect with the two collecting end joints 165.

[0049] Specifically, the trolley joint fixing plate 163 can be fixedly connected to the trolley main frame 13 by a fastener 168 .

[0050] Specifically, the trolley docking part 16 also includes a suspension joint fixing part 169, and the suspension joint 167 includes a suspension port 171 and a suspension guide 172. The suspension joint fixing part 169 is fixed to the trolley joint fixing plate 163, and the suspension joint fixing part 169 includes a positioning part 1691 extending into the matching space 161. The suspension guide 172 is sleeved on the collection end joint 165 and penetrates the suspension joint fixing part 169 to form a guide for the docking end joint of the docking device 30; the suspension port 171 is fixedly connected to the suspension guide 172, and the suspension port 171 can be floatably matched with the mounting hole of the suspension joint fixing part 169 to engage with the suspension joint fixing part 169 in the initial state. The suspension joint 167 can be floatably arranged in the mounting hole formed by the suspension joint fixing part 169, so that the suspension joint 167 can swing within a certain range in any direction relative to the trolley joint fixing plate 163, thereby achieving the guidance and position correction of the docking end joint. When the docking end connector of the docking device 30 is not connected, the suspension port 171 is engaged with the suspension connector fixing piece 169, and the suspension connector 167 is in the initial position; during the process of connecting the docking end connector, the suspension port 171 moves relative to the suspension connector fixing piece 169, and guides the docking end connector to align with the corresponding collection end connector 165 and complete the engagement to form a cleaning passage or a waste discharge passage.

[0051] Specifically, a first elastic member 175 is provided between the floating joint fixing member 169 and the floating joint 167 to reset the floating joint 167 so as to reset the floating port 171 from a movable state to a state of engagement with the floating joint fixing member 169. Specifically, the two ends of the first elastic member 175 abut against the floating joint fixing member 169 and the floating port 171, respectively. The first elastic member 175 may be a compression spring. When the docking end connector of the docking device 30 is not connected and the floating joint 167 is in an initial position, the first elastic member 175 is in an initial state, that is, the first elastic member 175 is not compressed or is only slightly compressed; when the floating joint 167 floats during the process of connecting the docking end connector, the first elastic member 175 is compressed; when the docking end connector is removed, the elastic force accumulated by the compression of the first elastic member 175 restores the floating joint 167 to its initial state.

[0052] Specifically, two mounting holes may be provided on the trolley joint fixing plate 163 to respectively install two suspension joint fixing members 169, thereby correspondingly providing two suspension joints 167, and respectively connecting two collecting end joints 165 through the two suspension joints 167. Specifically, the trolley joint fixing plate 163 includes a flat plate 1631 and a guide plate 1633, and the two guide plates 1633 are respectively connected to both ends of the flat plate 1631 and extend toward one side of the flat plate 1631. The mounting holes are provided on the flat plate 1631.

[0053] Specifically, the collecting end joint 165 and the floating joint 167 are fixedly connected to form a whole, and the outer walls of the collecting end joint 165 and the floating joint 167 can be integrally formed or connected by threads.

[0054] Specifically, the floating joint fixing member 169 includes a fixing top 1693, and the fixing top 1693 is fixedly connected to the trolley joint fixing plate 163. Specifically, a limiting portion 1695 is formed at the junction of the fixing top 1693 and the positioning portion 1691, and the limiting portion 1695 abuts against one side surface of the trolley joint fixing plate 163, and the other side surface of the trolley joint fixing plate 163 is provided with a first clamping member 176 that abuts against the trolley fixing plate 163 and clamps the fixing top 1693 of the floating joint fixing member 169, so that the fixing top 1693 is fixedly connected to the trolley joint fixing plate 163 through the limiting portion 1695 and the first clamping member 176. The first clamping member 176 can be specifically a clamping spring. Specifically, a matching hole 1696 is formed on the fixed top 1693, and the matching hole 1696 is a tapered hole with a larger top and a smaller bottom, or the inner side wall of the matching hole 1696 is an inclined plane, that is, at least part of the inner side wall of the matching hole 1696 faces away from the matching space 161, and the size of the matching hole 1696 gradually decreases. A cavity 1697 connected to the matching hole 1696 is formed in the positioning portion 1691, and the first elastic member 175 is accommodated in the cavity 1697, and one end of the first elastic member 175 abuts against the fixed top 1693. A first card slot 1699 for accommodating the first card connector 176 is formed on the floating joint fixing member 169.

[0055] Specifically, the suspension port 171 includes a mating surface for mating with the mating hole 1696 of the suspension joint fixing member 169, and the mating surface is a conical surface or an inclined plane, that is, the mating surface faces the matching space 161, and the mating surface is at least partially inclined. The mating surface of the suspension port 171 can fit with the inner surface of the mating hole 1696, and can also be separated from the mating hole 1696 as the suspension port 171 floats.

[0056] Specifically, the suspension guide 172 includes a sleeve portion 1720 and a guide end 1721 for guiding the docking end connector, one end of the sleeve portion 1720 is connected to the collecting end connector 165, and the guide end 1721 is connected to the other end of the sleeve portion 1720. The guide end 1721 is provided with a guide port 1722, which can be a conical hole, or the inner side wall of the guide port 1722 is a plurality of inclined planes, that is, the guide port 1722 is a bell mouth structure, which can be an arc surface or a conical surface. In this way, the guide port 1722 can guide the docking end connector of the docking device 30 during docking, so as to facilitate the position alignment during docking. One end of the suspension guide 172 extends from one end of the suspension joint fixing member 169 into the matching space 161, and the suspension guide 172 also includes a limiting edge 1725 that cooperates with the positioning portion 1691 to limit the upward floating range of the suspension joint 167 during floating, and the limiting edge 1725 is provided on the outer side wall of the guide end 1721. In this embodiment, the outer diameter of the limiting edge 1725 is greater than the outer diameter of the positioning portion 1691. When the suspension guide 172 moves upward to abut against the positioning portion 1691, the positioning portion 1691 can prevent the suspension guide 172 from continuing to move upward. Specifically, a chamfer 1726 is formed at one end of the guide end 1721 away from the limiting edge 1725. Specifically, the diameter of the position where the aperture of the guide port 1722 is the smallest can range from 40 mm to 60 mm. In this way, the size of the guide port 1722 is larger, so the tolerance space is larger. In addition, the diameter of the floating joint 167 ranges from 30 mm to 38 mm, and the inner diameter of the positioning portion 1691 ranges from 50 mm to 70 mm. In this way, the floating joint 167 can have a larger tilt angle range before completing the docking, and the floating joint 167 can be more conveniently guided to the docking.

[0057] Specifically, the suspension guide 172 further includes an outer tube 1727, which is connected to the outer wall of the guide end 1721 and sleeved outside the guide end 1721 to form a gap with the guide end 1721. One end of the first elastic member 175 abuts against the gap between the outer tube 1727 and the guide end 1721.

[0058] Specifically, a second clamping member 178 is provided on one side surface of the suspension port 171, which abuts against the suspension port 171 and clamps the suspension guide 172.

The suspension guide 172 is provided with a second clamping groove 1728 for accommodating the second clamping member 178.

[0059] Please refer to Figures 6 to 8In this embodiment, the docking device 30 includes a drainage station body 32 and a mating head 34, and the mating head 34 is disposed on one side of the drainage station body 32. The mating head 34 is used to mate with the trolley docking portion 16 of the waste collection device 10. Specifically, the mating head 34 is inserted into the mating space 161 of the trolley docking portion 16 to achieve preliminary alignment of the docking device 30 and the waste collection device 10.

[0060] In this embodiment, a drainage station guide 321 is further provided on the drainage station body 32. Two drainage station guides 321 are respectively provided on both sides of the drainage station guide part 321 to cooperate with the two sides of the trolley housing 12 respectively, so as to guide the docking device 30 in the process of the mating head 34 of the docking device 30 entering the mating space 161. Specifically, a second anti-collision part 323 is further provided on the side facing each other of the two drainage station guides 321. The second anti-collision part 323 can be a collision-proof roller to prevent the trolley housing 12 from being damaged by collision during docking. Specifically, a rounded corner 324 is formed at one end of the drainage station guide 321 away from the drainage station body 32 to better achieve guidance.

[0061] Specifically, a magnetic member 325 is further provided on the drainage station body 32. Specifically, the magnetic member 325 is provided on one side of the mating head 34. When the docking device 30 contacts the waste collection device 10, the magnetic member 325 is adsorbed together with the magnetic stopper 126 of the waste collection device 10, and at this time, the mating head 34 has completely entered the mating space 161.

[0062] Specifically, the drainage station body 32 includes a drainage station shell 327 and a drainage device disposed inside the drainage station shell 327 .

[0063] In this embodiment, the mating joint part 34 includes a butt joint 341 and an actuating assembly 343. The butt joint 341 is connected to the actuating assembly 343, which is disposed in the mating joint part 34 and can move freely in a specific direction, thereby driving the butt joint 341 to move to dock with the collecting end joint 165. When the mating joint part 34 is aligned with the trolley docking part 16, the actuating assembly 343 is actuated to make the butt joint 341 contact with the suspension joint 167, and the butt joint 34 makes the suspension joint 167 suspend and move to guide the butt joint 341 to engage with the collecting end joint 165. In this embodiment, one butt joint 341 is docked with one collecting end joint 165 to form a waste discharge passage for transporting waste in the waste collection container, and the other butt joint 341 is docked with the other collecting end joint 165 to form a passage for cleaning the waste collection container, which is used to transport the cleaning liquid for cleaning the waste collection container. Specifically, one of the docking end connectors 341 is connected to a cleaning interface on the drainage station body 32 for injecting cleaning liquid; the docking device 30 also includes a suction pump (not shown in the figure), which is used to connect to one of the docking end connectors 341 and discharge the waste sucked by the docking end connector 341 through the discharge connector on the drainage station body 32. Specifically, the actuating component 343 can be a pneumatic pump or a stepper motor, or other retractable components or mechanical structures. In this embodiment, a pneumatic pump is preferably used, which can reduce the circuit components of the docking device 30, thereby reducing circuit failures and reducing the potential risks of complex circuits to the equipment. Another point is that the speed and force of the pneumatic pump during the pushing process are more conducive to the guiding effect of the suspension connector 167 on the docking end connector 341.

[0064] Specifically, one end of the butt joint connector 341 that is butt jointed with the collection end connector 165 is provided with a rounded corner to guide the butt joint connector 341 and the suspension connector 167 during the butt joint process, thereby facilitating the butt joint.

[0065] In this embodiment, the mating head 34 further includes a mating head housing 345, and the butt end connector 341 and the actuating assembly 343 are both disposed in the mating head housing 345. The mating head housing 345 includes a front panel 3452 and side panels 3454 connected to both sides of the front panel 3452, and the rear end of the mating head housing 345 opposite to the front panel 3452 is connected to the liquid discharge station body 32.

[0066] In this embodiment, the mating head 34 also includes a mating plate 347, on which two guide bayonet holes 3471 are provided, and the butt-end joint 341 can pass through the guide bayonet holes 3471 accordingly. Specifically, the two guide bayonet holes 3471 are respectively used to pass through the two butt-end joints 341. Preferably, the guide bayonet holes 3471 are approximately U-shaped, with an inner end thereof being an arc surface, and a side end 3473 being a wedge-shaped structure, so that the opening width from the front end to the inner end of the guide bayonet holes gradually decreases. Such a structure enables the floating joint 167 to gradually align with the guide bayonet holes 3471 without causing a collision during the process of pushing the mating head 34 into the mating space 161 of the trolley docking part 16.

[0067] Specifically, an elastic hanging hole 3477 is provided on the adapter plate 347 .

[0068] Specifically, the adapter plate 347 is further provided with a first magnetic switch 3479 and a second magnetic switch 3480 , and the first magnetic switch 3479 and the second magnetic switch 3480 are both provided at the rear end of the adapter plate 347 (ie, the end away from the guide bayonet 3471 ).

[0069] In this embodiment, the mating joint part 34 further includes a cover plate 349, which is movably disposed above the mating plate 347. When the mating joint part 34 is pushed into the mating space 161, the waste collection device 10 pushes the cover plate 349 to stagger the cover plate 349 and the mating plate 347; after the mating joint part 34 is separated from the mating space 161, the cover plate 349 can be reset to a position that blocks the mating plate 349 and the butt joint 341.

[0070] Specifically, a slide groove is provided on the cover plate 349 , and guide rails 3481 slidably arranged in the slide groove are provided on both sides of the adapter plate 347 to guide the movement of the cover plate 349 .

[0071] Specifically, a second elastic member (not shown) is provided between the adapter plate 347 and the cover plate 349, and the second elastic member is used to provide an elastic force to automatically reset the cover plate 349 after the adapter head 34 is separated from the adapter space 161. More specifically, during the process of pushing the adapter head 34 into the adapter space 161, the elastic member is gradually stretched, and after the adapter head 34 is separated from the adapter space 161, it retracts and releases the elastic force. Specifically, an elastic member hanging portion 3491 is provided on the cover plate 349, and the two ends of the second elastic member are respectively connected to the elastic member hanging portion 3491 and the elastic member hanging hole 3477 on the adapter plate 347.

[0072] Specifically, the cover plate 349 is further provided with a first magnetic element 3493 and a second magnetic element 3494. The first magnetic element 3493 is provided at the rear end of the cover plate 349 (i.e., the end of the cover plate 349 facing away from the trolley docking portion 16), and the second magnetic element 3494 is provided at the front end of the cover plate 349 (i.e., the end of the cover plate 349 facing the trolley docking portion 16). When the first magnetic switch 3479 senses the first magnetic element 3493, it indicates that the docking device 30 and the waste treatment device 10 are ready to dock. When the second magnetic switch 3480 senses the second magnetic element 3493, it indicates that the docking head 34 has completely entered the docking space 161, and the actuating assembly 343 can start working for docking.

[0073] In this embodiment, the mating joint part 34 further includes a moving plate 351 , on which the docking end joint 341 is disposed. The actuating assembly 343 drives the moving plate 351 to move up and down, thereby driving the docking end joint 341 to move and dock with the collecting end joint 165 .

[0074] In this embodiment, the matching head 34 further includes a matching base plate 353, a support column 354 and a guide column 355, and the movable plate 351 is located between the matching base plate 353 and the matching plate 347. The support column 354 and the guide column 355 are fixed relative to the matching base plate 353, the matching plate 347 is fixedly connected to the support column 354, and the movable plate 351 is movably arranged on the guide column 355. Specifically, one end of the guide column 355 is also connected to the matching plate 347. The end of the support column 354 and the guide column 355 connected to the matching plate 347 is provided with a buffer pad 356, so as to reduce vibration and silence the movable plate 351 when it rises to a position close to the matching plate 347. Among them, one end of the support column 354 located between the two guide bayonet holes 3471 is connected to the matching head housing 345, and one end of the remaining support columns 354 is connected to the matching base plate 353.

[0075] Specifically, a bushing 3552 is sleeved on the guide post 355 to reduce the friction between the moving plate 351 and the guide post 355 when the moving plate 351 moves up and down.

[0076] In this embodiment, the fitting head 34 further includes a sensor bracket 357, on which a first sensor 3571 and a second sensor 3573 are arranged at intervals. A sensor block 3511 is provided on the movable plate 351, and the first sensor 3571 and the second sensor 3573 are used to sense the sensor block 3511. When the first sensor 3571 senses the sensor block 3511, the collection end connector 165 and the docking end connector 341 are successfully docked; when the work of the liquid discharge station body 32 is completed, the actuating assembly 343 drives the movable plate 351 and the docking end connector 341 to descend, and the first sensor 3571 and the sensor block 3511 are separated until the second sensor 3573 senses the sensor block 3511, indicating that the movable plate 351 and the docking end connector 341 have returned to their initial positions. The first sensor 3571 and the second sensor 3573 may be photoelectric sensors. When the first sensor 3571 senses the sensor block 3511, the first sensor 3571 lights up, and when the second sensor 3573 senses the sensor block 3511, the second sensor 3573 lights up. It can be understood that the sensor bracket 357 may also be omitted, and the first sensor 3571 and the second sensor 3573 may be disposed on other structures (such as the mating head housing 345), as long as the first sensor 3571, the second sensor 3573 and the mating plate 347 are relatively fixed.

[0077] In this embodiment, the mating head 34 further includes a charging port 359 for charging the waste collection device 10 through the charging receiving portion 162 of the trolley mating head 16. Specifically, the charging port 359 can be a wireless charging port, which can be charged by simply contacting or approaching the charging receiving portion 162.

[0078] In this embodiment, please refer to Fig. 9 and Fig.10 The outer side wall of the butt joint 341 is provided at the step portion 3411, one end of the butt joint 341 passes through the movable plate 351, the step portion 3411 abuts against one side of the movable plate 351, and the clamping member 3413 is clamped on the butt joint 341 and held on the other side of the movable plate 351, thereby fixing the butt joint 341 on the movable plate 351. Specifically, a gasket 3415 is further provided between the step portion 3411 and the movable plate 351, and between the clamping member 3413 and the movable plate 351. Specifically, the clamping member 3413 may be a retaining spring, and the gasket 3415 may be a polytetrafluoroethylene gasket.

[0079] In this embodiment, please refer to Fig.11 and Fig.12When the matching joint part 34 has not yet entered the matching space 161 of the trolley joint 16, the floating joint fixing part 169 is located on one side of the matching joint part 34, and the cover plate 349 is covered on the matching plate 347. Then the matching joint part 34 gradually extends into the matching space 161 of the trolley joint 16, and when the trolley joint fixing plate 163 contacts the cover plate 349, as the matching joint part 34 moves into the matching space 161, the trolley joint fixing plate 163 gradually pushes the cover plate 349 to move relative to the matching plate 347; in this process, the floating joint 167 gradually enters the guide bayonet 3471 until the collecting end joint 165 is roughly aligned with the docking end joint 341, and the guide bayonet 3471 guides the entry of the floating joint 167, and at this time, the positioning part 1691 of the floating joint fixing part 169 cooperates with the guide bayonet 3471 of the matching plate 347 to achieve preliminary positioning. Next, please refer to Fig.13 and Fig.14 , and then start the actuating assembly 343. The actuating assembly 343 is activated to make the butt-end joint 341 contact the floating joint 167, and make the floating joint 167 float to guide the butt-end joint 341 to engage with the collecting end joint 165.

[0080] In this embodiment, since the positioning part 1691 is arranged on the floating joint fixing part 169, after the positioning part 1691 is positioned with the guide bayonet 3471, the floating space of the floating joint 167 has no infinite position relationship with the adapter plate 347 and the guide bayonet 3471, and the floating space of the floating joint 167 will not be limited, so that the fault tolerance space during docking is large, and the floating joint 167 will not get stuck during the docking process. Before the docking is completed, the floating space of the floating joint 167 in the horizontal direction is related to the distance between the inner surface of the floating joint fixing part 169 and the outer surface of the floating guide 172, and the floating space of the floating joint 167 in the vertical direction is related to the distance between the bottom surface of the floating joint fixing part 169 and the limiting edge 1725 of the floating guide 172; the larger these two distances are, the larger the floating space is. The specific distances can be set according to the actual size of the equipment and the average value of the commonly used site conditions. The floating space can be completely unrestricted by the adapter part 34 of the drainage station. If necessary, a very large range of floating can be achieved by increasing these two distances.
