Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an abdominal drainage device for general surgical care. Background Technology

[0002] General surgery is a clinical discipline that primarily treats diseases of the liver, biliary tract, pancreas, gastrointestinal tract, anorectal tract, vascular system, thyroid and breast tumors, as well as other diseases caused by surgery. It is the largest specialty in the surgical system. Patients generally require nursing care after general surgery, which includes abdominal drainage. Abdominal drainage devices are usually used during abdominal drainage.

[0003] A general surgical abdominal drainage device is a medical device that drains intra-abdominal fluid, blood, pus, etc., to the outside of the body through siphon or negative pressure suction. Its core structure includes a drainage tube and a negative pressure drainage device. Some high-end models, such as the Weilang brand multi-functional drainage tube, are also equipped with a drug filling seat, a flushing and blockage removal seat, and an air filter. The design of the gap between the inner and outer tubes creates continuous negative pressure, which can not only avoid tissue damage caused by the adsorption of the single lumen tube, but also dilute viscous drainage materials with physiological saline and prevent blockage.

[0004] Current abdominal drainage devices typically involve inserting a puncture needle into the patient's body, then using a negative pressure mechanism in conjunction with a drainage tube to extract accumulated fluids and drain them into a drainage bag. However, after surgery, when multiple abdominal lavages are required, it is often necessary to remove part of the drainage device from the patient, treat the wound, and then disinfect the removed device before reassembling it for continued drainage. This process is overly cumbersome. Furthermore, manual disinfection can be difficult due to the viscosity of the patient's bodily fluids, potentially leading to incomplete disinfection and infection risks. Additionally, after drainage, the extracted fluids sometimes need to be tested, but current drainage devices struggle to sample these fluids. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an abdominal drainage device for general surgical care, in order to solve the technical problems that when performing abdominal lavage and continuing abdominal drainage on a patient, it is necessary to remove the drainage device, clean the patient's abdominal cavity, disinfect the drainage device, and reassemble it before use. Manual disinfection may lead to incomplete disinfection and the risk of infection. Furthermore, when it is necessary to perform laboratory tests on the patient's body, the existing drainage device is difficult to sample.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an abdominal drainage device for general surgical nursing, comprising a main body, a motor disposed inside the main body, a suction mechanism disposed at the output end of the motor, a connecting pipe disposed on one side of the suction mechanism, a liquid collection mechanism disposed at the bottom end of the main body, a disinfection mechanism disposed at the top end of the main body, a driving mechanism disposed between the disinfection mechanism and the liquid collection mechanism, a sampling mechanism disposed on one side of the main body, the disinfection mechanism comprising a disinfection box and a heating module, the disinfection box being fixedly connected to the main body by bolts and a plate, the heating module being fixedly installed between the disinfection box and the main body, the driving mechanism comprising pulleys, spring rods, a driving disc, and engaging grooves, wherein one set of pulleys is fixedly connected to the output end of the motor, and another set of pulleys is fixedly connected to multiple sets of spring rods on one side, the driving disc being located outside the multiple sets of spring rods, and multiple sets of engaging grooves being formed inside the driving disc, with a chamfered top on the engaging grooves.

[0007] By adopting the above technical solution, this invention, equipped with a heating module and a dynamic flushing system, can automatically disinfect and sterilize the drainage pipe. The drive mechanism, with its drive disc and crank, pulls the connecting pipe, and with the tightening device, periodic pipe deformation enhances the flushing effect of the disinfectant, ensuring thorough cleaning. A motor-driven peristaltic pump generates negative pressure, achieving stable and continuous fluid extraction. The peristaltic tube design avoids the efficiency reduction caused by blockages in traditional drainage methods. Furthermore, the collection tank features a narrow-bottomed, framed recovery port design to prevent liquid splashing. Centralized treatment of disinfected waste reduces the risk of environmental pollution and minimizes the chances of medical staff coming into contact with contaminants. A test tube is placed inside the sampling cup, which rotates via a damping shaft. With the cooperation of a baffle and a limiting block, it allows for the direct acquisition of body fluid samples during drainage without interrupting the drainage process, simplifying the testing procedure. Furthermore, the baffle prevents the sampling mechanism from being contaminated, thus solving the technical problem that manual disinfection may lead to incomplete disinfection and the risk of infection, as well as the difficulty of sampling with existing drainage devices when it is necessary to test the patient's body fluids.

[0008] Furthermore, a tensioning mechanism is provided on one side of the main body. The tensioning mechanism includes a movable rod, a movable roller, a tensioning spring, and a tensioning groove. The tensioning groove is opened on the outer side of the main body. The movable rod is rotatably connected to the main body and is located inside the tensioning groove. Both ends of the movable rod are rotatably connected to the movable roller. The movable rod and the main body are elastically connected by the tensioning spring.

[0009] The drive mechanism also includes a crank and a movable sleeve. The crank is fixedly connected to the drive disc, and the other end of the crank is rotatably connected to the movable sleeve. One end of the movable sleeve is movably connected to the connecting pipe. The drive mechanism also includes a fixed shaft and a belt. Two sets of pulleys are rotatably connected by the belt. One set of pulleys and the drive disc are both rotatably connected to the fixed shaft, and the fixed shaft supports the pulleys and the drive disc.

[0010] By adopting the above technical solution, when the drive disc rotates, it will drive the crank to rotate synchronously, thereby causing the movable sleeve to pull the connecting tube. When the crank rotates to the bottom of the drive disc, the connecting tube will be in a taut state. At this time, the connecting tube will enter the tensioning groove of the tensioning mechanism. The tensioned connecting tube will fit tightly with the movable rod, and the tensioned connecting tube will press the two sets of movable rollers, thereby causing the movable rod to tilt up at the other end through the lever principle, thus making the entire connecting tube taut. This causes the diameter inside the connecting tube to deform. After the connecting tube is taut, the disinfectant will pass through the connecting tube to better disinfect and clean the residual body fluid inside, thereby thoroughly disinfecting the connecting tube.

[0011] Furthermore, the extraction mechanism includes a drive shaft, a protective shell, a rotating frame, extrusion wheels, a peristaltic tube, and a discharge tube. The protective shell is fixedly connected to the main body by bolts and plates. The drive shaft is fixedly connected to the output end of the motor. One end of the drive shaft passes through the protective shell and is fixedly connected to the rotating frame. The outer side of the rotating frame is rotatably connected to multiple sets of extrusion wheels. The peristaltic tube is fixedly installed inside the protective shell and is located between the extrusion wheels and the protective shell. One end of the peristaltic tube is fixedly connected to the connecting pipe, and the other end of the peristaltic tube is fixedly connected to the discharge tube.

[0012] By adopting the above technical solution, when the motor is powered on, the output end of the motor will drive the extraction mechanism to start working. The drive shaft is driven by the motor to rotate, and the rotating frame is driven by the drive shaft to rotate together. Multiple sets of squeezing wheels are installed on the rotating frame. At this time, the squeezing wheels will rotate synchronously with the rotating frame, squeezing the peristaltic tube. The body fluid inside will be extracted from the patient's body through negative pressure. The body fluid then enters the extraction mechanism through the connecting tube, and then enters the discharge tube through the peristaltic tube.

[0013] Furthermore, the liquid collection mechanism includes a collection port, a collection tank, a baffle, and a torsion spring. The collection tank is movably connected to the main body and is located at the bottom of the main body. The collection port is located at the top of the collection tank and has a cross-section that is wider at the top and narrower at the bottom. One side of the collection port is rotatably connected to the baffle. The baffle is elastically connected to the collection port via the torsion spring. The liquid collection mechanism also includes a collection tank handle, collection tank rollers, and a slide rail. The collection tank handle is fixedly installed on the top of the collection tank. Multiple sets of collection tank rollers are fixedly connected to the bottom of the collection tank. A slide rail is provided at the bottom of the main body.

[0014] By adopting the above technical solution, the body fluid will fall into the recovery port at the top of the collection mechanism after passing through the discharge tube. It will then flow directly into the recovery box, thereby realizing the extraction of body fluid from the patient. After disinfection is completed and the drainage device is not used temporarily, the user can pull the collection box handle to pull the recovery box out from the main body, dispose of the waste liquid inside the recovery box, disinfect the recovery box, align the collection box rollers at the bottom of the recovery box with the slide rail inside the main body, and then place the recovery box into the main body.

[0015] Furthermore, the disinfection mechanism also includes an extraction tube and a fixing head. One end of the extraction tube is located inside the disinfection box, and the other end of the extraction tube passes through the heating module and the main body and is fixedly connected to the fixing head.

[0016] By adopting the above technical solution, a threaded sleeve is provided on the connector at the end of the pipe. Therefore, the connecting pipe and the fixed head can be fixedly connected by the threaded sleeve engaging with the external thread on the outer wall of the fixed head, so that the disinfection mechanism can be connected to the connecting pipe.

[0017] Furthermore, the sampling mechanism includes a sampling cup, a sampling handle, and a test tube. The sampling cup is rotatably connected to the main body via a damping shaft. One side of the sampling cup is fixedly connected to the sampling handle. The sampling cup has a groove inside that matches the size of the test tube. The test tube is placed inside the sampling cup. The sampling mechanism also includes a limiting block, which is fixedly installed inside the recovery port. The top of the limiting block has an inclined surface, and the limiting block serves to limit the position of the baffle.

[0018] By adopting the above technical solution, the user only needs to push or pull the sampling handle to rotate the sampling cup via the damping shaft at the bottom of the cup. After rotating the sampling cup inward, the cup will press against the baffle and rotate along with it until the baffle contacts the limiting block. At this point, the test tube will stop just below the discharge tube. The body fluid extracted from the patient will drip into the test tube along the discharge tube. After obtaining a sample, the user can pull the sampling handle to rotate the sampling cup outward, making it easier for the user to pick up the test tube and perform tests on the patient's body fluid. The baffle will then reset under the elastic action of the torsion spring.

[0019] In summary, the present invention has the following main beneficial effects:

[0020] 1. This invention, by equipping a heating module and a dynamic rinsing system, can automatically complete the disinfection and sterilization of the drainage pipe. The drive mechanism, with the cooperation of the drive disc and crank, pulls the connecting pipe, and with the tightening device, the periodic pipe deformation enhances the rinsing effect of the disinfectant, ensuring thorough cleaning without dead corners.

[0021] 2. This invention generates negative pressure by driving a peristaltic pump with a motor, achieving stable and continuous extraction of body fluids. The peristaltic tube design avoids the efficiency reduction problem caused by blockage in traditional drainage. The collection tank adopts a cross-section with a narrow upper frame and a narrow lower recovery port to prevent liquid splashing. The waste liquid after disinfection is centrally treated, reducing the risk of environmental pollution and reducing the chance of medical staff coming into contact with pollutants.

[0022] 3. This invention allows for the direct acquisition of bodily fluid samples during drainage by placing a test tube inside the sampling cup, which rotates via a damping shaft, and in conjunction with a baffle and a limiting block. This eliminates the need to interrupt the drainage process, simplifies the testing procedure, and prevents contamination of the sampling mechanism by the baffle. This solves the technical problem that manual disinfection may result in incomplete disinfection and the risk of infection, and that existing drainage devices struggle to collect samples when testing the patient's bodily fluids.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of the present invention will now be described.

[0039] An abdominal drainage device for general surgical nursing, such as Figure 1-13 As shown, it includes a main body 1, a motor 2 inside the main body 1, an extraction mechanism 3 at the output end of the motor 2, a connecting pipe 4 on one side of the extraction mechanism 3, a liquid collection mechanism 5 at the bottom inside the main body 1, a disinfection mechanism 6 at the top inside the main body 1, a drive mechanism 8 between the disinfection mechanism 6 and the liquid collection mechanism 5, and a sampling mechanism 9 on one side of the main body 1. First, the user can move the main body 1 to any position by pushing the handle and the casters, push the main body 1 to the side of the patient who needs drainage, and then turn on the power.

[0040] Furthermore, the disinfection mechanism 6 includes a disinfection box 601 and a heating module 603. The disinfection box 601 is fixedly connected to the main body 1 by bolts and plates. The heating module 603 is fixedly installed between the disinfection box 601 and the main body 1. The disinfectant solution enters the heating module 603 after passing through the extraction tube 602. The heating module 603 is electrically connected to the motor 2. After the motor 2 enters the rapid rotation mode, the heating module 603 starts to be powered on to heat the disinfectant solution that has passed through the heating module 603.

[0041] Furthermore, the drive mechanism 8 includes pulleys 802, spring rods 803, a drive disc 804, and engaging grooves 805. One set of pulleys 802 is fixedly connected to the output end of the motor 2, and another set of pulleys 802 is fixedly connected to multiple sets of spring rods 803 on one side. The drive disc 804 is located outside the multiple sets of spring rods 803, and multiple sets of engaging grooves 805 are formed inside the drive disc 804. The top of the engaging grooves 805 is chamfered. When the motor 2 increases its rotation speed, the pulleys 802 connected to its output end will... The belt 808 drives another set of pulleys 802 to rotate rapidly. Therefore, the spring rod 803 installed on one of the pulleys 802 will be stretched by the centrifugal force of the spring inside the spring rod 803 under the rapid rotation of the pulley 802, until the spring rod 803 is engaged in the engagement groove 805. One end of the engagement groove 805 is chamfered to facilitate the entry of the spring rod 803. Therefore, the pulley 802 can drive the drive disc 804 to rotate synchronously.

[0042] In the example, the extraction mechanism 3 includes a drive shaft 301, a protective shell 302, a rotating frame 303, a squeezing wheel 304, a peristaltic tube 305, and a discharge tube 306. The protective shell 302 is fixedly connected to the main body 1 by bolts and plates. The drive shaft 301 is fixedly connected to the output end of the motor 2. One end of the drive shaft 301 passes through the protective shell 302 and is fixedly connected to the rotating frame 303. The outer side of the rotating frame 303 is rotatably connected to multiple sets of squeezing wheels 304. The peristaltic tube 305 is fixedly installed inside the protective shell 302 and is located between the squeezing wheel 304 and the protective shell 302. One end of the peristaltic tube 305 is fixedly connected to the connecting pipe 4, and the other end of the peristaltic tube 305 is fixedly connected to the discharge tube 306.

[0043] When motor 2 is energized, its output will drive the extraction mechanism 3 to start working. The drive shaft 301 is rotated by motor 2, and the rotating frame 303 is rotated together with the drive shaft 301. Multiple sets of squeezing wheels 304 are installed on the rotating frame 303. The squeezing wheels 304 will rotate synchronously with the rotating frame 303, squeezing the peristaltic tube 305. The body fluid inside will be extracted from the patient's body through negative pressure. The body fluid then enters the extraction mechanism 3 through the connecting tube 4, and then enters the discharge tube 306 through the peristaltic tube 305.

[0044] In the example, the liquid collection mechanism 5 includes a collection port 501, a collection box 502, a baffle 503, and a torsion spring 507. The collection box 502 is movably connected to the main body 1 and is located at the bottom of the main body 1. The collection port 501 is opened at the top of the collection box 502 and has a cross-section that is wider at the top and narrower at the bottom. One side of the inside of the collection port 501 is rotatably connected to the baffle 503. The baffle 503 is elastically connected to the collection port 501 through the torsion spring 507. The liquid collection mechanism 5 also includes a collection box handle 504, a collection box roller 505, and a slide rail 506. The collection box handle 504 is fixedly installed on the top of the collection box 502. Multiple sets of collection box rollers 505 are fixedly connected to the bottom of the collection box 502. A slide rail 506 is opened at the bottom of the main body 1.

[0045] After passing through the discharge tube 306, the body fluid will fall into the collection port 501 at the top of the collection mechanism 5. After passing through the collection port 501, it will flow directly into the collection box 502, thereby realizing the extraction of body fluid from the patient. After disinfection is completed and the drainage device is not used temporarily, the user can pull the collection box handle 504 to pull the collection box 502 out from the main body 1. After the waste liquid inside the collection box 502 is treated and the collection box 502 is disinfected, the collection box roller 505 at the bottom of the collection box 502 is aligned with the slide rail 506 inside the main body 1, and the collection box 502 can be placed into the main body 1.

[0046] In the example, the disinfection mechanism 6 also includes an extraction tube 602 and a fixing head 604. One end of the extraction tube 602 is located inside the disinfection box 601, and the other end of the extraction tube 602 passes through the heating module 603 and the main body 1 and is fixedly connected to the fixing head 604. A threaded sleeve is provided on the connector at the end of the tube 4. Therefore, the connecting tube 4 and the fixing head 604 can be fixedly connected by the threaded sleeve engaging with the external thread on the outer wall of the fixing head 604, so that the disinfection mechanism 6 is connected to the connecting tube 4.

[0047] In the example, a tensioning mechanism 7 is provided on one side of the main body 1. The tensioning mechanism 7 includes a movable rod 701, a movable roller 702, a tension spring 703, and a tension groove 704. The tension groove 704 is opened on the outer side of the main body 1. The movable rod 701 is rotatably connected to the main body 1 and is located inside the tension groove 704. Both ends of the movable rod 701 are rotatably connected to the movable roller 702. The movable rod 701 and the main body 1 are elastically connected by the tension spring 703. The drive mechanism 8 also includes a crank 8. 06 and movable sleeve 807, crank 806 is fixedly connected to drive disk 804, the other end of crank 806 is rotatably connected to movable sleeve 807, one end of movable sleeve 807 is movably connected to connecting pipe 4, drive mechanism 8 also includes fixed shaft 801 and belt 808, two sets of pulleys 802 are rotatably connected by belt 808, one set of pulleys 802 and drive disk 804 are both rotatably connected to fixed shaft 801, and fixed shaft 801 plays a supporting role for pulleys 802 and drive disk 804;

[0048] When the drive disc 804 rotates, it drives the crank 806 to rotate synchronously, which in turn causes the movable sleeve 807 to pull the connecting pipe 4. When the crank 806 rotates to the bottom of the drive disc 804, the connecting pipe 4 will be in a taut state. At this time, the connecting pipe 4 will enter the tensioning groove 704 of the tensioning mechanism 7. The tensioned connecting pipe 4 will fit tightly with the movable rod 701, and the tensioned connecting pipe 4 will press the two sets of movable rollers 702, which will cause the other end of the movable rod 701 to lift up through the lever principle, thereby tauting the entire connecting pipe 4 and deforming the internal diameter of the connecting pipe 4. After the connecting pipe 4 is taut, the disinfectant will pass through the connecting pipe 4 to better disinfect and clean the residual body fluid inside, thus thoroughly disinfecting the connecting pipe 4.

[0049] In the example, the sampling mechanism 9 includes a sampling cup 901, a sampling handle 902, and a test tube 9040. The sampling cup 901 is rotatably connected to the main body 1 through a damping shaft. One side of the sampling cup 901 is fixedly connected to the sampling handle 902. The sampling cup 901 has a groove inside that matches the size of the test tube 904. The test tube 904 is placed inside the sampling cup 901. The sampling mechanism 9 also includes a limiting block 903. The limiting block 903 is fixedly installed inside the recovery port 501. The top of the limiting block 903 has an inclined surface. The limiting block 903 serves to limit the position of the baffle 503.

[0050] The user only needs to push or pull the sampling handle 902 to rotate the sampling cup 901 via the damping pivot at the bottom. After rotating the sampling cup 901 inward into the main body 1, the sampling cup 901 will press against the baffle 503 and drive the baffle 503 to rotate together until the baffle 503 contacts the limiting block 903. At this time, the test tube 904 will just stop below the discharge tube 306. The body fluid extracted from the patient will drip down the discharge tube 306 into the test tube 904. After obtaining a sample, the user can pull the sampling handle to rotate the sampling cup 901 outward into the main body 1, which makes it easier for the user to pick up the test tube 904 and thus facilitate the user to test the patient's body fluid. The baffle 503 will return to its original position under the elastic action of the torsion spring 507.

[0051] The working principle of this invention is as follows: When in use, the user can first move the main body 1 to any position by pushing the handle and the caster wheel. After pushing the main body 1 to the side of the patient who needs drainage, the power is turned on to energize the electrical components inside the main body 1.

[0052] At this point, medical staff first insert a puncture needle into the patient's body at the location where drainage is needed, and fix the position of the puncture needle and drainage tube. Then, they take out the connecting tube 4, which is made of elastic rubber material. The end of the connecting tube 4 is equipped with a connector, and the connector is tapered. Therefore, after connecting the connector to the drainage tube, the tapered connector can fit tightly with the drainage tube, thereby ensuring that the body fluid in the patient's body will not flow out and avoiding the possibility of infection.

[0053] After the connector and drainage tube are installed, start the motor 2 to power it. The output of the motor 2 will drive the extraction mechanism 3 to start working. The drive shaft 301 is rotated by the motor 2. One end of the drive shaft 301 is inserted into the protective shell 302 and fixedly connected to the rotating frame 303. Therefore, the rotating frame 303 will be rotated together with the drive shaft 301. Multiple sets of extrusion rollers 304 are installed on the rotating frame 303. At this time, the extrusion rollers 304 will rotate synchronously with the rotating frame 303.

[0054] When the squeezing wheel 304 rotates with the rotating frame 303, it will squeeze the peristaltic tube 305. The squeezed peristaltic tube 305 forms a sealed structure with the patient's body through the connecting tube 4. After the peristaltic tube 305 is squeezed, the body fluid in the patient's body will be extracted through negative pressure. At this time, the body fluid enters the extraction mechanism 3 through the connecting tube 4, and then enters the discharge tube 306 through the peristaltic tube 305.

[0055] After passing through the discharge tube 306, the body fluid will fall into the recovery port 501 at the top of the collection mechanism 5. Since the cross-section of the recovery port 501 is a conical structure with a larger top and a smaller bottom, it prevents the body fluid flowing out of the discharge tube 306 from falling outside the collection mechanism 5. The body fluid will flow directly into the recovery box 502 after passing through the recovery port 501, thereby realizing the extraction of body fluid from the patient's body.

[0056] When it is necessary to sample the patient's body fluids, a test tube 904 can be placed in the sampling cup 901 in the sampling mechanism 9. The sampling cup 901 has a cavity that matches the size of the test tube 904, so the test tube 904 will move along with the sampling cup 901.

[0057] During sampling, the user only needs to push or pull the sampling handle 902 to rotate the sampling cup 901 via the damping pivot at the bottom of the sampling cup 901. After rotating the sampling cup 901 inward into the main body 1, the sampling cup 901 will press against the baffle 503 and drive the baffle 503 to rotate together until the baffle 503 contacts the limiting block 903. At this time, the test tube 904 will just stop below the discharge tube 306. The body fluid extracted from the patient will drip down the discharge tube 306 into the test tube 904. After obtaining a sample, the user can pull the sampling handle to rotate the sampling cup 901 outward into the main body 1, which makes it convenient for the user to pick up the test tube 904 and thus facilitate the user to test the patient's body fluid. The baffle 503 will be reset under the elastic action of the torsion spring 507.

[0058] After the drainage is completed, the drainage device needs to be disinfected. The connecting tube 4 is removed and connected to the disinfection mechanism 6. Since the connector at the end of the connecting tube 4 is provided with a threaded sleeve, the connecting tube 4 and the fixing head 604 can be fixedly connected by the threaded sleeve engaging with the external thread on the outer wall of the fixing head 604, so that the disinfection mechanism 6 is connected to the connecting tube 4.

[0059] At this time, the user can control the output end of the motor 2 to rotate rapidly, so that the extraction mechanism 3 can quickly extract the disinfectant liquid inside the disinfection box 601. After the disinfectant liquid passes through the extraction tube 602, it will enter the heating module 603. The heating module 603 is electrically connected to the motor 2. After the motor 2 enters the rapid rotation mode, the heating module 603 will start to be powered on to heat the disinfectant liquid that has passed through the heating module 603.

[0060] The heated disinfectant enters the connecting pipe 4, passes through the extraction mechanism 3, and is then discharged into the collection mechanism 5. As the extraction speed of the extraction mechanism 3 increases at this time, the disinfectant will spray out from the discharge pipe 306. However, the outlet of the discharge pipe 306 is aligned with the baffle 503, so the sprayed disinfectant will be blocked by the baffle 503 and then flow into the recycling tank 502.

[0061] Furthermore, after the motor 2 increases its rotation speed, the pulley 802 connected to its output end will drive another set of pulleys 802 to rotate rapidly via the belt 808. Therefore, the spring rod 803 installed on one of the pulleys 802 will overcome the elastic force of the spring inside the spring rod 803 through centrifugal force under the rapid rotation of the pulley 802, causing the length of the spring rod 803 to be stretched until the spring rod 803 is engaged in the engagement groove 805. One end of the engagement groove 805 is chamfered to facilitate the entry of the spring rod 803. Therefore, the pulley 802 can drive the drive disc 804 to rotate synchronously.

[0062] When the body fluids in the patient's body are extracted as described above, the output end of the motor 2 will also drive the pulley 802 to rotate. However, the speed of the motor 2 is not enough to make the spring rod 803 overcome the elastic force of its internal spring. Therefore, the spring rod 803 will not be engaged in the engagement groove 805, so the drive disc 804 will not rotate synchronously with the pulley 802.

[0063] When the drive disc 804 rotates, it will drive the crank 806 to rotate synchronously, thereby causing the movable sleeve 807 to pull the connecting pipe 4. When the crank 806 rotates to the bottom of the drive disc 804, the connecting pipe 4 will be in a taut state.

[0064] At this time, the connecting tube 4 will enter the tensioning groove 704 of the tensioning mechanism 7. After being tensioned, the connecting tube 4 will fit tightly with the movable rod 701, and the tensioned connecting tube 4 will press the two sets of movable rollers 702, so that the movable rod 701 will be lifted by lever principle, thereby making the connecting tube 4 as a whole tensile, and thus causing the diameter inside the connecting tube 4 to deform.

[0065] After the connecting tube 4 is tightened, the disinfectant will better disinfect and clean the residual body fluid inside the connecting tube 4, thus thoroughly disinfecting the connecting tube 4.

[0066] After the crank 806 rotates to the top of the drive disc 804, the connecting pipe 4 will enter a relaxed state. At this time, the movable rod 701 will be reset under the elastic action of the tension spring 703. Then, the connecting pipe 4 will continuously switch between the tension and relaxation states under the rotation of the crank 806. Under the rinsing of the disinfectant, it is ensured that there is no residual body fluid inside the connecting pipe 4.

[0067] After disinfection is completed and the drainage device is not used for the time being, the user can open the side door on one side of the main body 1, pull the collection tank handle 504 to pull the recovery tank 502 out of the main body 1, treat the waste liquid inside the recovery tank 502, disinfect the recovery tank 502, align the collection tank roller 505 at the bottom of the recovery tank 502 with the slide rail 506 inside the main body 1, and then put the recovery tank 502 into the main body 1.

[0068] The above structure solves the technical problem that when performing abdominal lavage and continuing abdominal drainage on a patient, the drainage device needs to be removed before the patient's abdominal cavity is cleaned, and then the drainage device needs to be disinfected and reassembled before it can be used. Manual disinfection may lead to incomplete disinfection and the risk of infection. Furthermore, when the patient's body needs to be tested, the existing drainage device is difficult to sample.
