Description

Technical Field

[0001] The present invention relates to the technical field of medical waste liquid separation, and particularly 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 originate from multiple medical places such as wards, operating rooms, laboratories, delivery rooms, etc., including but not limited to various waste waters, excreta, pharmaceutical waste liquids, surgical waste liquids, etc.;

[0003] In the prior art, the waste liquid is mostly guided into the interior of the collection cylinder by means of negative pressure and then the liquid is separated from the tissue fragments. The negative pressure extraction is carried out by two one-way pipes connected to the cylinder body for input and output. The air inside the filter cylinder is pumped out through the output pipe, and then the waste liquid from the outside is introduced into the cylinder body through the output pipe. However, in actual use, the connection between the input pipe and the output pipe and the cylinder body is usually inconvenient. When it is necessary to disassemble and connect the input pipe and the output pipe, it takes a long time. Especially 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

[0004] 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 art.

[0006] As a further solution of the present invention, absorbent cotton is arranged inside the port below the output pipe.

[0007] As a further solution of the present invention, a receiving member is provided below the adsorption cotton. The receiving member is located below the cover plate. Two extension edges are fixedly connected to the side wall of the receiving member. Positioning edges are provided below both of the two extension edges, and both of the two positioning edges are fixedly connected to the ports located below the output pipe.

[0008] 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 near the top end of the round rod. Two positioning grooves are vertically formed in the top end of the cover plate.

[0009] As a further solution of the present invention, the bottom end of the round rod extends into the interior of the cylinder body. A rotating ring is slidably connected to the bottom end of the round rod. The rotating ring is rotatably connected to the cover plate. A plurality of scraping rods are rotatably connected to the bottom end of the rotating ring.

[0010] As a further solution of the present invention, a pressing member is slidably connected to the receiving member. Through holes are formed in both the receiving member and the pressing member. The pressing member is located above the adsorption cotton. The bottom end of the pressing member is located below the receiving member and is provided with a through hole. A plug rod is provided on one side of the through hole. The end of the plug rod is wedge-shaped. The plug rod is slidably connected to the cover plate. A third spring is fixedly connected between the plug rod and the cover plate. A push rod is fixedly connected to the side wall of the rotating ring. The push rod is bent. When the push rod rotates 90 degrees following the rotating ring, the plug rod can be moved to one side to contact the through hole and press down the through hole.

[0011] As a further solution of the present invention, sealing grooves are formed in the bottoms of the collar rings, and sealing strips are arranged inside the sealing grooves.

[0012] As a further solution of the present invention, a plurality of blocking members are fixedly connected to the inner wall of the cylinder body, and the blocking members are used for supporting the filter frame.

[0013] As a further solution of the present invention, a handle is arranged on the filter frame.

[0014] As a further solution of the present invention, a discharge end is arranged at the bottom end of the cylinder body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In the present invention, when connecting and disconnecting the input pipe and the output pipe, by pulling up the driving rod, the pressing piece is rotated to the vertical state to avoid blocking the insertion of the input pipe and the output pipe. After the input pipe and the output pipe are inserted into the inner part of the collar, the driving rod is released, and after the pressing piece rotates to the horizontal state, the connecting edge is pressed down to be closely attached to the collar. Then, after the driving rod descends to the limit, the collar is directly pressed down to the position where it fits the port. At this time, the collar, the connecting edge and the port will form a seal under the action of the downward pressure to complete the connection. When disassembling, only the driving rod needs to be pulled up and then the input pipe and the output pipe are taken out. The process of disassembly and connection is simple, takes a short time, and does not affect normal work.

[0017] Before connection, the collar is pushed above the limiting ring under the action of the first spring. At this time, it is convenient for the direct insertion of the input pipe and the output pipe, and can initially limit the input pipe and the output pipe to prevent the input pipe and the output pipe from detaching from the collar under the action of the flexibility and toughness of the pipeline. Moreover, the collar is close to the upper part, which is convenient for the direct connection of the short-distance joints of the input pipe and the output pipe to the collar without the need to laboriously insert it downward and avoid detaching from the hands of the operator. When the driving rod descends, the pressing of the connecting edge by the pressing piece causes it to descend to a sealed state while being close to the collar, which can avoid slackness and also make the joint part less exposed to form protection. When disassembling, the input pipe and the output pipe are directly pushed upward by the collar to facilitate removal.

[0018] When the input pipe sucks the external waste liquid into the inside of the cylinder, the amount of the waste liquid is not constant and is sucked intermittently. When the amount of the waste liquid decreases and the suction port of the input pipe cannot be immersed in the waste liquid, the suction of the waste liquid will be intermittent and accompanied by bubbles. Then, the waste liquid sucked into the cylinder by the input pipe will also spread intermittently to the surrounding area, which easily causes the output pipe to directly suck away the moisture or a small amount of tissue fragments in the waste liquid discharged by the input pipe when pumping out the air inside the cylinder. By providing the adsorption cotton, the moisture in the gas flowing into the output pipe can be blocked, thereby avoiding the potential hazards caused by the direct discharge of medical waste liquid.

DETAILED DESCRIPTION

[0040] See also Figures 1 - 19 The 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.

[0041] like Figure 1 , Figure 2 , Figure 4 as well as Figures 6 - 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.

[0042] Connection work of input pipe 1 and output pipe 2:

[0043] First pull the drive rod 8 upward to the highest point (i.e. Figure 1the state shown in the figure, at this time the second spring 9 is in a state of being stretched to the limit;

[0044] When the input pipe 1 or the output pipe 2 is not connected, the pressing piece 10 is in the state as shown in Figure 6 , Figure 7 , Figure 9 , and Figure 10 shown in the figure, that is, at this time the bottom end of the pressing piece 10 is in a vertically downward state, so that it will not be blocked by the pressing piece 10 when the input pipe 1 and the output pipe 2 are inserted subsequently. At this time, the input pipe 1 can be directly inserted into the collar 6 inside the limiting ring 5. At this time, the bottom end of the connecting edge 19 will be in contact with the top end of the collar 6 (as shown in Figure 11 shown in the figure). At this time, the input pipe 1 can be preliminarily restricted by the collar 6 and the limiting ring 5 with an inner diameter equal to the diameter of the connecting edge 19, so that the joint of the input pipe 1 will not become loose. Since the parts above the joints of the input pipe 1 and the output pipe 2 are pipes, and the pipes have flexibility and toughness, the restriction of the input pipe 1 by the collar 6 and the limiting ring 5 can prevent the joints of the input pipe 1 and the output pipe 2 from detaching from the collar 6 and the limiting ring 5 under the action of the ductility of the pipes;

[0045] When both the input pipe 1 and the output pipe 2 are inserted into the inside of the collar 6, release the upward pull on the driving rod 8 so that the driving rod 8 can descend to the limit under the elastic reset action of the second spring 9. During the descent of the driving rod 8, the end parts at both ends thereof will rotate and slide along the inside of the notch 32 on the pressing piece 10. At this time, the pressing piece 10 will change from the state shown in Figure 7 to the state shown in Figure 8 shown in the figure, and during the rotation of the pressing piece 10, it will not be blocked by the connecting edge 19 and the collar 6 (that is, the collar 6 is located below the connecting member 11). At this time, the bottom end of the pressing piece 10 will be in a horizontal state after rotating ninety degrees (as shown in Figure 12 shown in the figure). After the pressing piece 10 rotates ninety 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 descend while maintaining a horizontal state;

[0046] When the bottom wall of the pressing piece 10 in the 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 member 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 limiting 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 end of the port 31. At this time, the port 31, the collar 6 and the connecting edge 19 form a seal in the pressed state (as shown in Figure 12 shown in the figure), thereby completing the connection of the input pipe 1 and the output pipe 2;

[0047] Then, the air inside the cylinder 4 can be pumped out through the output pipe 2. At this time, the input pipe 1 can suck the waste liquid into the inside of the cylinder 4 through negative pressure. The setting of the filter frame 12 can separate the waste liquid from the tissue fragments. When it is necessary to take out the filter frame 12 inside the cylinder 4, just open the cover plate 3.

[0048] Disassembly of the input pipe 1 and the output pipe 2:

[0049] Lift the drive rod 8 upward to the extreme. During this process, the first spring 7 will push the collar 6 upward, thereby pushing the input pipe 1 and the output pipe 2 upward to a position close to the top of the limit ring 5, facilitating the removal of the input pipe 1 and the output pipe 2. During the upward movement of the drive rod 8, the connecting edge 19 will first remain in contact with the pressing piece 10 so that the pressing piece 10 will not immediately rotate from the horizontal state to the vertical state. When the collar 6 rises a small distance, the pressing piece 10 will rotate ninety degrees to the vertical state. At this time, the drive rod 8 continues to drive the connecting member 11 to slide upward inside the limit ring 5. At this time, the pressing piece 10 will also release the block on the connecting edge 19. At this time, just pull out the input pipe 1 and the output pipe 2 upward. After the input pipe 1 and the output pipe 2 are pulled out, just release the drive rod 8 and let it drop to the extreme.

[0050] When the present invention connects and disassembles the input pipe 1 and the output pipe 2, by pulling up the drive rod 8, the pressing piece 10 is rotated to the vertical state 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, release the drive rod 8. After the pressing piece 10 rotates to the horizontal state, press down the connecting edge 19 until it fits tightly with the collar 6. Then, after the drive rod 8 drops to the extreme, directly press down the collar 6 to a position where it 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 pressing force to complete the connection. When disassembling, just pull up the drive rod 8 and then pull out the input pipe 1 and the output pipe 2. The disassembly and connection processes are simple, time-consuming, and do not affect normal work.

[0051] Before connection, the collar 6 is pushed above the limiting ring 5 under the action of the first spring 7. At this time, it is convenient to directly insert the input pipe 1 and the output pipe 2, and can initially limit the input pipe 1 and the output pipe 2 to prevent the input pipe 1 and the output pipe 2 from detaching from the collar 6 due to the flexibility and toughness of the pipeline. Moreover, with the collar 6 close to the upper part, it is convenient for the short-distance joints of the input pipe 1 and the output pipe 2 to be directly connected to the collar 6 without the need to laboriously insert it downward and avoid detaching from the hands of the operator. When the driving rod 8 descends, the pressing piece 10 presses down on the connecting edge 19 so that it descends to be sealed while being close to the collar 6. While avoiding slackness, it can also make the joint part less exposed to form protection, and when disassembling, the input pipe 1 and the output pipe 2 can be directly pushed upward by the collar 6 to facilitate removal.

[0052] An absorbent cotton 13 is arranged inside the port 31 below the output pipe 2.

[0053] As Figure 4 , Figures 16 - 19 shown, by arranging the absorbent cotton 13 inside the port 31 below the output pipe 2, the moisture contained in the air can be filtered. When the input pipe 1 sucks the external waste liquid into the interior of the cylinder 4, the amount of the waste liquid is not constant and is sucked intermittently. When the amount of the waste liquid decreases and the suction port of the input pipe 1 cannot be immersed in the waste liquid, the suction of the waste liquid will be intermittent and accompanied by bubbles. Then, the waste liquid sucked into the interior of the cylinder 4 by the input pipe 1 will also spread intermittently to the surroundings, which easily causes the output pipe 2 to directly suck away the moisture or a small amount of tissue fragments in the waste liquid discharged by the input pipe 1 when pumping the air inside the cylinder 4 to the outside. However, the arranged absorbent cotton 13 can block the moisture in the gas flowing into the interior of the output pipe 2, thereby avoiding the hidden danger caused by the direct discharge of medical waste liquid.

[0054] A receiving member 20 is arranged below the absorbent cotton 13. The receiving member 20 is located below the cover plate 3. Two extension edges 21 are fixedly connected to the side wall of the receiving member 20. Below each of the two extension edges 21, a positioning edge 22 is arranged. Both of the two positioning edges 22 are fixedly connected to the port 31 below the output pipe 2.

[0055] As Figure 4 , Figure 5 , Figures 16 - 19As shown, when the adsorption cotton 13 is installed inside the port 31, it is located above the receiving member 20. Then, align the extension edge 21 above the receiving member 20 to the middle position between the two positioning edges 22. At this time, directly push the receiving member 20 upward. When the extension edge 21 rises above the positioning edge 22, rotate the receiving member 20 so that the extension edge 21 can move above the positioning edge 22. At this time, directly lower the receiving member 20 so that the bump below the extension edge 21 enters the fixing groove above the positioning edge 22; the bump and the fixing groove are not specifically described, and they are used for positioning when the extension edge 21 fits with the positioning edge 22, so that the extension edge 21 and the receiving member 20 will not rotate.

[0056] 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 end of the round rod 14. Two positioning grooves 16 are vertically formed at the top end of the cover plate 3.

[0057] As Figure 1 、 Figure 4 、 Figure 6 and Figure 15 As shown, when the driving rod 8 is at the lowest position, that is, when the second spring 9 is not stretched, the positioning plate 15 is inside the lower positioning groove 16. When it is necessary to pull up the driving rod 8, first rotate the round rod 14 to make the positioning plate 15 rotate out of the lower positioning groove 16, and then the driving rod 8 can be pulled up. When the driving rod 8 is pulled up to the limit, rotate the round rod 14 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 collar 6 without continuously pulling the driving rod 8.

[0058] The bottom end of the round rod 14 extends into the inside of the cylinder body 4. A rotating ring 17 is slidably connected to the position of the bottom end of the round rod 14. The rotating ring 17 is rotatably connected to the cover plate 3. A plurality of scraping rods 18 are rotatably connected to the bottom end of the rotating ring 17.

[0059] As 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 scraping rods 18 to rotate. When the scraping rods 18 rotate, they can scrape off the tissue fragments attached to the inner wall of the cylinder body 4 that diffuse out along with the water vapor at the bottom end of the input pipe 1, and then directly make them fall into the inside of the filter frame 12. When the driving rod 8 moves up and down, the round rod 14 can slide inside the rotating ring 17.

[0060] A pressing member 23 is slidably connected to the receiving member 20. Through holes are provided in both the receiving member 20 and the pressing member 23. The pressing member 23 is located above the adsorption cotton 13. The bottom end of the pressing member 23 is located below the receiving member 20 and is provided with a through hole 24. A plug rod 25 is provided on one side of the through hole 24. The end of the plug rod 25 is wedge-shaped. The plug rod 25 is slidably connected to the cover plate 3. A third spring 26 is fixedly connected between the plug rod 25 and the cover plate 3. A push rod 27 is fixedly connected to the side wall of the rotating ring 17. The push rod 27 is bent. When the push rod 27 rotates 90 degrees following the rotating ring 17, the plug rod 25 can be moved to one side to contact the through hole 24 and press down the through hole 24.

[0061] As Figure 4 , Figure 5 , Figure 15 , Figures 17 - 19 shown, after the receiving member 20 is installed on the port 31 through the extension edge 21 and the positioning edge 22, the through hole 24 is on one side of the plug rod 25, and the pressing member 23 is slidably connected to the adsorption cotton 13 and the receiving member 20. When the round rod 14 rotates, the push rod 27 will rotate towards the plug rod 25. After the bent part of the push rod 27 rotates to contact the plug rod 25, it will push the plug rod 25 to slide along the cover plate 3 and compress the third spring 26. At this time, the wedge-shaped part at the end of the plug rod 25 will contact the bottom wall of the through hole 24 and then press down the through hole 24. At this time, the pressing 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 carried out. When the round rod 14 resets, the push rod 27 can be separated from the plug rod 25 and then the plug rod 25 resets.

[0062] Sealing grooves 28 are provided at the bottom of the collar 6, and sealing strips are provided inside the sealing grooves 28.

[0063] As Figures 10 - 14 shown: When the collar 6 contacts the top of the port 31, the top end of the port 31 will directly insert into the sealing groove 28 and contact the sealing strip, thereby enhancing the sealing performance. The top end of the collar 6 can also selectively be provided with a sealing strip to enhance the sealing effect.

[0064] A plurality of blocking members 29 are fixedly connected to the inner wall of the cylinder body 4, and the blocking members 29 are used to support the filter frame 12.

[0065] A handle is provided on the filter frame 12.

[0066] As Figure 2 and Figure 3 shown, the filter frame 12 is supported by a plurality of blocking members 29 distributed in a ring on the inner wall of the cylinder body 4, so that the filter frame 12 can be directly lifted out from the inside of the cylinder body 4 for convenient taking.

[0067] The bottom end of the cylinder body 4 is provided with a discharge end 30.

[0068] As Figure 2 shown, a plug plate is arranged inside the discharge end 30. When it is necessary to remove the waste liquid inside the cylinder body 4, the plug plate can be directly opened.
