Description

Technical Field

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

[0002] Medical waste liquid refers to liquid waste generated during medical activities. These waste liquids may come from multiple medical places such as wards, operating rooms, laboratories, delivery rooms, etc., including but not limited to various types of wastewater, excrement, drug waste liquid, surgical waste liquid, etc. In the prior art, waste liquid is mostly guided into the interior of a collection tube by means of negative pressure to separate the liquid from tissue fragments, and negative pressure extraction is performed by two one-way pipes for input and output connected to the cylinder body, and the air inside the filter cylinder is extracted through the output pipe, and then the output pipe introduces waste liquid from the outside into the cylinder body. However, in actual use, the connection between the input pipe and the output pipe and the cylinder body is usually inconvenient, and it takes a long time to disassemble and connect the input pipe and the output pipe. In particular, when the input pipe and the output pipe need to be replaced multiple times, the long disassembly and connection time is likely to affect the efficiency of the normal operation. Summary of the invention

[0003] The purpose of the present invention is to provide a medical waste liquid separation and treatment device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a medical waste liquid separation and treatment device, comprising an input pipe and an output pipe, both of which are fixedly connected with connecting edges, and also comprising: a cover plate, on which ports for docking with the input pipe and the output pipe are opened; a cylinder, which is arranged below the cover plate and is detachably connected to the cover plate; two limit rings, which are symmetrically distributed about the cover plate and are respectively sleeved on the outside of the two ports, and the limit rings are fixedly connected to the cover plate; two sleeve rings, which are respectively slidably connected to the inside of the two limit rings, and the sleeve rings are connected to the limit rings A first spring is fixedly connected between the circles; a driving rod is located between the two limiting circles and is slidably connected to the cover plate, and a second spring is fixedly connected between the driving rod and the cover plate; four pressing plates, two of which form a group, and the two groups of pressing plates are respectively arranged at the left and right ends of the driving rod, and the pressing plates are all slidably connected to the driving rod and can rotate; four connecting members, two of which form a group, and the two groups of connecting members are respectively slidably connected to the two limiting circles, and the four pressing plates are respectively rotatably connected to the four connecting members; a filter frame is arranged inside the cylinder.

[0005] As a further solution of the present invention, adsorption cotton is arranged inside the port below the output pipe.

[0006] As a further solution of the present invention, a receiving part is provided below the adsorption cotton, and the receiving part is located below the cover plate. The side wall of the receiving part is fixedly connected with two extended edges, and positioning edges are provided below the two extended edges. The two positioning edges are fixedly connected to the port located below the output pipe.

[0007] As a further solution of the present invention, a round rod is rotatably connected to the driving rod, a positioning plate is fixedly connected to a position of the round rod near the top, and two positioning grooves are provided at the top of the cover plate in the vertical direction.

[0008] As a further solution of the present invention, the bottom end of the round rod extends to the inside of the cylinder, the bottom end of the round rod is slidably connected to a swivel, the swivel is rotatably connected to the cover plate, and the bottom end of the swivel is rotatably connected to a plurality of scraping rods.

[0009] As a further solution of the present invention, an extrusion piece is slidably connected to the receiving piece, and both the receiving piece and the extrusion piece are provided with through holes. The extrusion piece is located above the adsorption cotton, and the bottom end of the extrusion piece is located below the receiving piece and is provided with a through hole. An insertion rod is provided on one side of the through hole, and the end of the insertion rod is wedge-shaped. The insertion rod is slidably connected to the cover plate, and a third spring is fixedly connected between the insertion rod and the cover plate. A push rod is fixedly connected to the side wall of the rotating ring, and the push rod is bent. When the push rod rotates ninety degrees with the rotating ring, the insertion rod can be moved to one side to a position where it contacts the through hole and presses down the through hole.

[0010] As a further solution of the present invention, a sealing groove is provided at the bottom of each of the collars, and a sealing strip is provided inside each of the sealing grooves.

[0011] As a further solution of the present invention, a plurality of blocking members are fixedly connected to the inner wall of the cylinder, and the blocking members are used to support the filter frame.

[0012] As a further solution of the present invention, a handle is provided on the filter frame.

[0013] As a further solution of the present invention, a discharge end is arranged at the bottom end of the cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects: According to the present invention, when the input pipe and the output pipe are connected and disassembled, the pressing plate is rotated to a vertical state by pulling up the driving rod to avoid blocking the insertion of the input pipe and the output pipe. When the input pipe and the output pipe are inserted into the inside of the collar, the driving rod is loosened and the connecting edge is pressed down to a degree of close fit with the collar after the pressing plate is rotated to a horizontal state. Then, after the driving rod is lowered to a limit, the collar is directly pressed down to a position that fits with the port. At this time, the collar, the connecting edge and the port form a seal under the action of downward pressure to complete the connection. When disassembling, it is only necessary to pull up the driving rod and then pull out the input pipe and the output pipe. The disassembly and connection process is simple and short in time and does not affect normal work.

[0015] Before connection, the collar is pushed to the top of the limit ring under the action of the first spring, which can facilitate the direct insertion of the input pipe and the output pipe, and can preliminarily limit the input pipe and the output pipe to prevent the input pipe and the output pipe from being separated from the collar due to the softness and toughness of the pipe. The collar is close to the top, which can facilitate the direct connection of the short-distance joint of the input pipe and the output pipe with the collar without the need to insert it downward and avoid separation from the operator's hands. When the drive rod descends, the pressing piece presses down on the connecting edge so that it is close to the collar and descends to a seal. While avoiding looseness, it can also make the joint less exposed to form protection. When disassembling, the input pipe and the output pipe are directly pushed upward by the collar to facilitate removal.

[0016] When the input tube sucks the external waste liquid into the interior of the cylinder, the amount of waste liquid is not constant and is absorbed intermittently. When the amount of waste liquid decreases, the suction port of the input tube cannot be immersed in the waste liquid, and the suction of the waste liquid will be intermittent and accompanied by bubbles. Then the waste liquid sucked into the cylinder by the input tube will also spread to the surroundings intermittently, which will easily lead to the output tube directly sucking away the water or a small amount of tissue fragments in the waste liquid discharged by the input tube when the air inside the cylinder is sucked out. The adsorption cotton set can block the water in the gas flowing into the output tube, thereby avoiding the hidden dangers caused by the direct discharge of medical waste liquid.

[0019] Please refer to Figure 1-Figure 19The present invention provides a technical solution: a medical waste liquid separation and treatment device, comprising an input pipe 1 and an output pipe 2, both of which are fixedly connected with a connecting edge 19, a cover plate 3, a cylinder 4, two limiting rings 5, two sleeve rings 6, a driving rod 8, four pressing sheets 10, four connecting pieces 11 and a filter frame 12, the cover plate 3 is provided with a port 31 connected with the input pipe 1 and the output pipe 2; the cylinder 4 is arranged below the cover plate 3 and is detachably connected with the cover plate 3; the two limiting rings 5 ​​are symmetrically distributed with respect to the cover plate 3 and are respectively sleeved on the outside of the two ports 31, and the limiting rings 5 ​​are both fixedly connected with the cover plate 3; the two sleeve rings 6 are respectively slidably ... It is connected to the inside of the two limiting rings 5, and a first spring 7 is fixedly connected between the ring 6 and the limiting ring 5; the driving rod 8 is located between the two limiting rings 5 ​​and is slidably connected to the cover plate 3, and a second spring 9 is fixedly connected between the driving rod 8 and the cover plate 3; four pressing plates 10, two pressing plates 10 form a group, and the two groups of pressing plates 10 are respectively arranged at the left and right ends of the driving rod 8, and the pressing plates 10 are all slidably connected to the driving rod 8 and can rotate; four connecting members 11, two connecting members 11 form a group, and the two groups of connecting members 11 are respectively slidably connected to the two limiting rings 5, and the four pressing plates 10 are respectively rotatably connected to the four connecting members 11; the filter frame 12 is arranged inside the cylinder 4.

[0020] like Figure 1 , Figure 2 , Figure 4 as well as Figure 6-Figure 15 As shown, the cover plate 3 and the cylinder body 4 are detachably connected, and the two can be fixed by fasteners. The fasteners can be one or more of the prior art, which will not be described in detail here. The second spring 9 is arranged so that the driving rod 8 can be stretched when it is lifted and lowered along the cover plate 3, and the second spring 9 is at the bottom when it is not stretched. Connection work of input pipe 1 and output pipe 2: First pull the drive rod 8 upward to the highest point (i.e. Figure 1 The state shown), at this time, the second spring 9 is in a state of being stretched to the limit; When the input pipe 1 or the output pipe 2 is not connected, the pressing piece 10 is in the state as follows Figure 6 , Figure 7 , Fig. 9 ,as well as Fig.10 In the state shown, the bottom end of the pressing sheet 10 is in a vertical downward state, so that the subsequent input tube 1 and the output tube 2 will not be blocked by the pressing sheet 10 when they are inserted. At this time, the input tube 1 can be directly inserted into the ring 6 inside the limiting ring 5. At this time, the bottom end of the connecting edge 19 will fit with the top end of the ring 6 (as shown in FIG. Fig.11As shown), at this time, the input pipe 1 can be initially restricted by the collar 6 and the limiting ring 5 whose inner diameter is the same as the diameter of the connecting edge 19, so that the joint of the input pipe 1 will not be loosened. Because the part above the joint of the input pipe 1 and the output pipe 2 is a pipeline, and the pipeline has flexibility and toughness, the restriction of the input pipe 1 by the collar 6 and the limiting ring 5 can prevent the joint of the input pipe 1 and the output pipe 2 from being separated from the collar 6 and the limiting ring 5 due to the toughness of the pipeline; After the input tube 1 and the output tube 2 are inserted into the inner part of the collar 6, the upward pull on the driving rod 8 is released so that the driving rod 8 can be lowered to the limit under the elastic return action of the second spring 9. During the lowering process of the driving rod 8, the ends of both ends of the driving rod 8 will rotate and slide along the inner part of the notch 32 on the pressing plate 10. At this time, the pressing plate 10 will be Figure 7 The status changes to Figure 8 The state shown in the figure, and the pressing piece 10 will not be blocked by the connecting edge 19 and the ring 6 during the rotation process (that is, the ring 6 is located below the connecting member 11), and the bottom end of the pressing piece 10 will be in a horizontal state after rotating to 90 degrees (such as Fig.12 As shown), after the pressing piece 10 rotates to 90 degrees, it will be blocked by the side wall of the connecting member 11 and cannot continue to rotate. At this time, when the driving rod 8 continues to descend, it will drive the pressing piece 10 to maintain a horizontal state and descend; When the bottom wall of the pressing piece 10 in a horizontal state contacts the top of the connecting edge 19, it will continue to descend under the elastic reset of the second spring 9. At this time, the pressing piece 10, the connecting piece 11, the connecting edge 19 and the collar 6 will all descend. At this time, the first spring 7 will be pressed down, and the connecting edge 19 will remain in contact with the collar 6. At this time, the input pipe 1 and the output pipe 2 will descend inside the limit ring 5. When the driving rod 8 descends to the limit, the bottom end of the collar 6 descends to a position in contact with the top of the port 31. At this time, the port 31, the collar 6 and the connecting edge 19 form a seal in a compressed state (such as Fig.12 As shown), the input pipe 1 and the output pipe 2 are connected; Then, the air inside the cylinder 4 can be pumped out through the output pipe 2, and the input pipe 1 can pump the waste liquid into the cylinder 4 through negative pressure. The waste liquid and tissue fragments can be separated from the waste liquid by setting the filter frame 12. When the filter frame 12 inside the cylinder 4 needs to be taken out, the cover plate 3 can be opened; Disassembly of input pipe 1 and output pipe 2: The driving rod 8 is lifted upward to the limit. During this process, the first spring 7 will push the collar 6 upward, and then the input pipe 1 and the output pipe 2 are pushed upward to the position close to the top of the limiting ring 5, so as to facilitate the removal of the input pipe 1 and the output pipe 2. During the rising process of the driving rod 8, the connecting edge 19 will first maintain the fit with the pressing piece 10 so that the pressing piece 10 will not immediately rotate from the horizontal state to the vertical state. After the collar 6 rises a small distance, the pressing piece 10 will rotate ninety degrees to the vertical state. At this time, the driving rod 8 continues to drive the connecting piece 11 to slide up inside the limiting ring 5. At this time, the pressing piece 10 will also release the obstruction of the connecting edge 19. At this time, the input pipe 1 and the output pipe 2 can be directly pulled upward. After the input pipe 1 and the output pipe 2 are pulled out, the driving rod 8 can be directly released to make it drop to the limit. When the input pipe 1 and the output pipe 2 are connected and disassembled, the pressing piece 10 is rotated to a vertical state by pulling up the driving rod 8 to avoid blocking the insertion of the input pipe 1 and the output pipe 2. After the input pipe 1 and the output pipe 2 are inserted into the collar 6, the driving rod 8 is released, and the pressing piece 10 is rotated to a horizontal state and the connecting edge 19 is pressed down to a degree of close fit with the collar 6. Then, after the driving rod 8 is lowered to a limit, the collar 6 is directly pressed down to a position that fits with the port 31. At this time, the collar 6, the connecting edge 19 and the port 31 will form a seal under the action of downward pressure to complete the connection. When disassembling, it is only necessary to pull up the driving rod 8 and then pull out the input pipe 1 and the output pipe 2. The disassembly and connection process is simple, the time is short, and it does not affect normal work. Before connection, the collar 6 is pushed to the top of the limit ring 5 under the action of the first spring 7, which can facilitate the direct insertion of the input pipe 1 and the output pipe 2, and can preliminarily limit the input pipe 1 and the output pipe 2 to prevent the input pipe 1 and the output pipe 2 from being separated from the collar 6 due to the softness and toughness of the pipes. The collar 6 is close to the top, which can facilitate the direct connection of the short-distance joint of the input pipe 1 and the output pipe 2 with the collar 6 without the need to insert it downward and avoid separation from the operator's hands. When the driving rod 8 descends, the pressing piece 10 presses down on the connecting edge 19 so that it is close to the collar 6 and descends to a seal. While avoiding looseness, it can also make the joint less exposed to form protection. When disassembling, the input pipe 1 and the output pipe 2 are directly pushed upward by the collar 6 to facilitate removal.

[0021] The port 31 below the output tube 2 is provided with adsorption cotton 13 inside.

[0022] like Figure 4 , Figure 16-Figure 19As shown, by arranging adsorbent cotton 13 inside the port 31 below the output tube 2, the moisture contained in the air can be filtered. Because when the input tube 1 sucks the external waste liquid into the cylinder 4, the amount of waste liquid is not constant, but is absorbed intermittently. When the amount of waste liquid decreases, the suction port of the input tube 1 cannot be immersed in the waste liquid, and the suction of the waste liquid will be intermittent and accompanied by bubbles. Then, the waste liquid sucked into the cylinder 4 by the input tube 1 will also diffuse to the surroundings intermittently, which will easily lead to the output tube 2 directly sucking away the moisture or a small amount of tissue fragments in the waste liquid discharged by the input tube 1 when the air inside the cylinder 4 is sucked out. The adsorbent cotton 13 can block the moisture in the gas flowing into the output tube 2, thereby avoiding the hidden dangers caused by the direct discharge of medical waste liquid.

[0023] A receiving part 20 is provided below the adsorption cotton 13 , and the receiving part 20 is located below the cover plate 3 . The side wall of the receiving part 20 is fixedly connected to two extended edges 21 , and positioning edges 22 are provided below the two extended edges 21 . The two positioning edges 22 are fixedly connected to the port 31 located below the output pipe 2 .

[0024] like Figure 4 , Figure 5 , Figure 16-Figure 19 As shown, the adsorbent cotton 13 is located above the receiving part 20 when it is installed inside the port 31, and then the extended edge 21 on the receiving part 20 is aligned to the middle position of the two positioning edges 22. At this time, the receiving part 20 is directly pushed upward. When the extended edge 21 rises to above the positioning edge 22, the receiving part 20 is rotated so that the extended edge 21 can move to above the positioning edge 22. At this time, the receiving part 20 is directly lowered so that the protrusion under the extended edge 21 enters into the fixed groove above the positioning edge 22; the protrusion and the fixed groove are not described in detail. They are used to position the extended edge 21 and the positioning edge 22 when they are in contact, so that the extended edge 21 and the receiving part 20 will not rotate.

[0025] A round rod 14 is rotatably connected to the driving rod 8 , a positioning plate 15 is fixedly connected to a position near the top of the round rod 14 , and two positioning grooves 16 are formed at the top of the cover plate 3 along the vertical direction.

[0026] like Figure 1 , Figure 4 , Figure 6 and Fig.15As shown, when the driving rod 8 is at the bottom, that is, the second spring 9 is not stretched, the positioning plate 15 is inside the positioning groove 16 located below. When the driving rod 8 needs to be pulled up, the round rod 14 is rotated to make the positioning plate 15 rotate out from the inside of the positioning groove 16 below, and then the driving rod 8 can be pulled up. When the driving rod 8 is pulled up to the limit, the round rod 14 is rotated again to make the positioning plate 15 rotate into the upper positioning groove 16. At this time, the driving rod 8 will not drop, and then the input pipe 1 and the output pipe 2 can be inserted into the inside of the ring 6 without continuously maintaining the stretching of the driving rod 8.

[0027] The bottom end of the round rod 14 extends to the inside of the cylinder 4 , and a swivel 17 is slidably connected to the bottom end of the round rod 14 . The swivel 17 is rotatably connected to the cover plate 3 , and a plurality of scraper rods 18 are rotatably connected to the bottom end of the swivel 17 .

[0028] like Figure 2 , Figure 4 As shown, when the round rod 14 rotates following the positioning plate 15, it will drive the rotating ring 17 and the scraper rod 18 to rotate. When the scraper rod 18 rotates, it can scrape off the tissue fragments attached to the inner wall of the cylinder 4 that diffuse out along with the water vapor at the bottom end of the input pipe 1, and then make them fall directly into the filter frame 12. When the driving rod 8 is raised or lowered, the round rod 14 can slide inside the rotating ring 17.

[0029] An extrusion piece 23 is slidably connected to the receiving piece 20, and both the receiving piece 20 and the extrusion piece 23 are provided with through holes. The extrusion piece 23 is located above the adsorbent cotton 13, and the bottom end of the extrusion piece 23 is located below the receiving piece 20 and is provided with a through hole 24. An insertion rod 25 is provided on one side of the through hole 24, and the end of the insertion rod 25 is wedge-shaped. The insertion rod 25 is slidably connected to the cover plate 3, and a third spring 26 is fixedly connected between the insertion rod 25 and the cover plate 3. A push rod 27 is fixedly connected to the side wall of the swivel 17, and the push rod 27 is bent. When the push rod 27 rotates ninety degrees following the swivel 17, the insertion rod 25 can be moved to one side to a position where it contacts the through hole 24 and presses down the through hole 24.

[0030] like Figure 4 , Figure 5 , Fig.15 , Figure 17-Figure 19As shown, when the receiving member 20 is installed on the port 31 through the extended edge 21 and the positioning edge 22, the through hole 24 is on one side of the insertion rod 25, and the extrusion member 23 is slidably connected with the adsorption cotton 13 and the receiving member 20. When the round rod 14 rotates, the push rod 27 will rotate in the direction of the insertion rod 25. After the bent portion of the push rod 27 rotates to contact the insertion rod 25, it will push the insertion rod 25 to slide along the cover plate 3 and compress the third spring 26. At this time, the wedge-shaped portion at the end of the insertion rod 25 will contact the bottom wall of the through hole 24 and then press the through hole 24 downward. At this time, the extrusion member 23 will slide down along the receiving member 20 and compress the adsorption cotton 13. By compressing the adsorption cotton 13, it is possible to avoid containing more moisture inside after long-term adsorption, and by pressing down the adsorption cotton 13, drainage can be performed. When the round rod 14 is reset, the push rod 27 can be separated from the insertion rod 25 and the insertion rod 25 can be reset.

[0031] The bottom of the collar 6 is provided with a sealing groove 28 , and the inside of the sealing groove 28 is provided with a sealing strip.

[0032] like Figure 10-14 As shown, when the collar 6 contacts the top of the port 31, the top of the port 31 will be directly inserted into the sealing groove 28 and contact the sealing strip, thereby enhancing the sealing performance. The top of the collar 6 can also be selectively provided with a sealing strip to enhance the sealing effect.

[0033] A plurality of stoppers 29 are fixedly connected to the inner wall of the cylinder 4 , and the stoppers 29 are used to support the filter frame 12 .

[0034] The filter frame 12 is provided with a handle.

[0035] like Figure 2 and Figure 3 As shown, the filter frame 12 is supported by a plurality of stoppers 29 distributed in an annular shape on the inner wall of the cylinder 4, so that the filter frame 12 can be directly lifted upward from the inside of the cylinder 4 for easy removal.

[0036] The bottom end of the cylinder 4 is provided with a discharge end 30 .

[0037] like Figure 2 As shown, a plug plate is provided inside the discharge end 30, and when the waste liquid inside the cylinder 4 needs to be removed, the plug plate can be directly opened.
