Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an abdominal drainage device for general surgical care. Background Art

[0002] General surgery is a clinical discipline that uses surgery as the main method to treat liver, bile duct, pancreas, gastrointestinal, anorectal, vascular diseases, thyroid and breast tumors and trauma and other diseases. It is the largest specialty in the surgical system. Generally, patients need to be cared for after general surgery, including abdominal drainage. Usually, an abdominal drainage device is used for abdominal drainage.

[0003] The abdominal drainage device for general surgical nursing is a medical device that drains intra-abdominal fluid, blood, pus, etc. to the outside of the body through the principle of 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 Weilan brand multi-functional drainage tube, are also equipped with a dosing seat, a flushing and deblocking seat, and an air filter. The gap between the inner and outer sleeves is designed to form a continuous negative pressure, which can not only avoid damage to the tissue adsorbed by the single-lumen tube, but also dilute the viscous drainage material through saline flushing to prevent blockage.

[0004] The abdominal drainage device in the prior art is usually a puncture needle inserted into the patient's body, and then a negative pressure mechanism is used to cooperate with the drainage tube to extract the accumulated body fluids in the patient's body and discharge them into the drainage bag. However, when the patient needs to undergo multiple abdominal lavages after surgery, it is often necessary to first remove part of the drainage device from the patient and then treat the patient's wound. When it is necessary to continue abdominal drainage, medical staff also need to disinfect the removed drainage device and then assemble the drainage device. The overall operation is too cumbersome, and when manual disinfection is performed, the viscosity of the patient's body fluids may make it difficult to disinfect the inside of the drainage device, which may easily lead to incomplete disinfection and the risk of infection. After the patient is drained, it is sometimes necessary to test the body fluids extracted from the patient's body, but it is difficult to sample the patient's body fluids with the existing drainage device. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a peritoneal drainage device for general surgical nursing, so as to solve the technical problem that when performing peritoneal lavage on the patient and continuing peritoneal drainage, the drainage device needs to be removed to clean the patient's abdominal cavity, and then the drainage device needs to be disinfected and reassembled before use. Manual disinfection may lead to incomplete disinfection and the risk of infection. In addition, when the patient's experience needs to be tested, it is difficult to take samples with the existing drainage device.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A peritoneal drainage device for general surgical care, comprising a main body, a motor is arranged inside the main body, an extraction mechanism is arranged at the output end of the motor, a connecting pipe is arranged on one side of the extraction mechanism, a liquid collection mechanism is arranged at the bottom end of the main body, a disinfection mechanism is arranged at the top end of the main body, a driving mechanism is arranged between the disinfection mechanism and the liquid collection mechanism, a sampling mechanism is arranged on one side of the main body, the disinfection mechanism comprises a disinfection box and a heating module, the disinfection box is fixedly connected to the main body by the cooperation of bolts and plates, the heating module is fixedly installed between the disinfection box and the heating module, the driving mechanism comprises a pulley, a spring rod, a driving disc, and a clamping groove, wherein one group of the pulleys is fixedly connected to the output end of the motor, and one side of the other group of the pulleys is fixedly connected to multiple groups of spring rods, the driving disc is located outside the multiple groups of spring rods, and multiple groups of clamping grooves are provided inside the driving disc, and the top of the clamping groove is chamfered.

[0007] By adopting the above technical solution, the present invention is equipped with a heating module and a dynamic flushing system, which can automatically complete the disinfection and sterilization of the drainage pipe. The driving disc and the crank in the driving mechanism cooperate to pull the connecting pipe, and then cooperate with the tensioning device to enhance the flushing effect of the disinfectant through periodic pipe deformation, ensuring cleaning without dead angles. The motor drives the peristaltic pump to generate negative pressure to achieve stable and continuous body fluid extraction, and the peristaltic tube design can avoid the problem of efficiency reduction caused by blockage in traditional drainage, and the liquid collection box adopts a recovery port design with a frame on the top and a narrow bottom on the bottom to prevent liquid splashing. The waste liquid after disinfection is centrally treated to reduce the risk of environmental pollution and the chance of medical staff being exposed to pollutants. A test tube is placed in the sampling cup, and the sampling cup rotates through the damping shaft, and cooperates with the baffle and the limit block to support direct acquisition of body fluid samples during the drainage process without interrupting the drainage process, simplifying the laboratory operation steps, and the presence of the baffle prevents the sampling mechanism from being contaminated, thereby solving the technical problem that manual disinfection may lead to incomplete disinfection and the risk of infection, and when the patient's body fluid needs to be tested, the existing drainage device is difficult to sample.

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

[0009] The driving mechanism also includes a crank and a movable sleeve. The crank is fixedly connected to the driving disk, the other end of the crank is rotatably connected to the movable sleeve, and one end of the movable sleeve is movably connected to the connecting pipe. The driving mechanism also includes a fixed shaft and a belt. The two groups of pulleys are rotatably connected by belts, one group of the pulleys and the driving disk are both rotatably connected to the fixed shaft, and the fixed shaft plays a supporting role for the pulleys and the driving disk.

[0010] By adopting the above technical solution, when the driving disk rotates, the crank will be driven to rotate synchronously, so that the movable sleeve will pull the connecting tube. When the crank rotates to the bottom of the driving disk, the connecting tube will be in a tightened state. At this time, the connecting tube will enter the tightening groove of the tightening mechanism. The tightened connecting tube will fit tightly with the movable rod, and the tightened connecting tube will press the two sets of movable rollers, so that the movable rod will tilt the other end of the movable rod through the lever principle, so that the connecting tube as a whole is tightened, and the diameter inside the connecting tube is deformed. After the connecting tube is tightened, the disinfectant passing through the connecting tube will better disinfect and clean the residual body fluids inside, so that the connecting tube can be thoroughly disinfected.

[0011] Furthermore, the extraction mechanism includes a drive shaft, a protective shell, a rotating frame, an extrusion wheel, a peristaltic tube and a discharge pipe. The protective shell is fixedly connected to the main body by the cooperation of 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 groups of extrusion wheels. The peristaltic tube is fixedly installed inside the protective shell, and the peristaltic tube is located between the extrusion wheel and the protective shell. One end of the peristaltic tube is fixedly connected to the connecting tube, and the other end of the peristaltic tube is fixedly connected to the discharge pipe.

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

[0013] Furthermore, the liquid collecting mechanism includes a recovery port, a recovery box, a baffle and a torsion spring. The recovery box is movably connected to the main body, and the recovery box is located at the bottom end of the main body. The recovery port is opened at the top of the recovery box, and the cross-section of the recovery port is wide at the top and narrow at the bottom. One side of the interior of the recovery port is rotatably connected to the baffle, and the baffle is elastically connected to the recovery port through a torsion spring. The liquid collecting mechanism also includes a liquid collecting box handle, a liquid collecting box roller and a slide rail. The liquid collecting box handle is fixedly installed on the top of the recovery box, and multiple groups of liquid collecting box rollers are fixedly connected to the bottom of the recovery box. A slide rail is opened at the bottom end of the main body.

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

[0015] Furthermore, the disinfection mechanism also includes an extraction tube and a fixed 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 fixed head.

[0016] By adopting the above technical solution, a threaded sleeve is provided on the connecting head at the end of the connecting pipe, so that the threaded sleeve can cooperate with the external thread of the outer wall of the fixed head to fix the connecting pipe and the fixed head, so that the disinfection mechanism is 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 through a damping shaft. One side of the sampling cup is fixedly connected to the sampling handle. A groove matching the size of the test tube is provided inside the sampling cup. The test tube is placed inside the sampling cup. The sampling mechanism also includes a limit block, which is fixedly installed inside the recovery port, and a slope is provided on the top of the limit block, and the limit block serves to limit the baffle.

[0018] By adopting the above technical solution, the user only needs to push and pull the sampling handle to rotate the sampling cup through the damping shaft at the bottom of the sampling cup. After rotating the sampling cup toward the inside of the main body, the sampling cup will press against the baffle and drive the baffle to rotate together until the baffle contacts the limit block. At this time, the test tube will just stay below the discharge tube. At this time, the body fluid extracted from the patient's body will drip into the inside of the test tube along the discharge tube. After obtaining a part of the sample, the user pulls the sampling handle to rotate the sampling cup toward the outside of the main body, which makes it convenient for the user to take the test tube, and then facilitates the user to test the patient's body fluid, and the baffle will be reset under the elastic action of the torsion spring.

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

[0020] 1. The present invention is equipped with a heating module and a dynamic flushing system to automatically complete the disinfection and sterilization of drainage pipes. The driving disc and crank in the driving mechanism cooperate to pull the connecting pipe, and then cooperate with the tensioning device to enhance the flushing effect of the disinfectant through periodic pipe deformation, ensuring no dead corner cleaning;

[0021] 2. The present invention uses a motor-driven peristaltic pump to generate negative pressure, achieving stable and continuous body fluid extraction. The peristaltic tube design can avoid the efficiency loss caused by blockage in traditional drainage. The collection tank adopts a recovery port design with a cross-section that is narrow at the bottom and wide at the top to prevent liquid splashing. The waste liquid after disinfection is centrally processed, reducing the risk of environmental pollution and the chance of medical staff being exposed to pollutants.

[0022] 3. The present invention places a test tube in the sampling cup, and the sampling cup rotates through a damping shaft, and cooperates with the baffle and the limit block to support direct acquisition of body fluid samples during the drainage process without interrupting the drainage process, simplifying the test operation steps. The presence of the baffle prevents the sampling mechanism from being contaminated, thereby solving the technical problems that manual disinfection may lead to incomplete disinfection and the risk of infection, and that the existing drainage device is difficult to sample when the patient's body fluid needs to be tested.

[0038] The following describes an embodiment of the present invention based on its overall structure.

[0039] A general surgical nursing abdominal drainage device, such as Figure 1-13 As shown, it includes a main body 1, a motor 2 is provided inside the main body 1, an extraction mechanism 3 is provided at the output end of the motor 2, a connecting tube 4 is provided on one side of the extraction mechanism 3, a liquid collection mechanism 5 is provided at the bottom end of the main body 1, a disinfection mechanism 6 is provided at the top end of the main body 1, a driving mechanism 8 is provided between the disinfection mechanism 6 and the liquid collection mechanism 5, and a sampling mechanism 9 is provided 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 universal wheel. After pushing the main body 1 to the side of the patient who needs drainage, the power is turned on.

[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 the cooperation of bolts and plates. The heating module 603 is fixedly installed between the disinfection box 601 and the heating module 603. After the disinfectant passes through the extraction tube 602, it will enter the interior of the heating module 603. The heating module 603 is electrically connected to the motor 2. After the motor 2 enters the fast rotation mode, the heating module 603 starts to be energized for heating, thereby heating the disinfectant passing through the heating module 603.

[0041] Furthermore, the driving mechanism 8 includes a pulley 802, a spring rod 803, a driving disc 804, and a snap-fitting groove 805, wherein one set of pulleys 802 is fixedly connected to the output end of the motor 2, and one side of the other set of pulleys 802 is fixedly connected to multiple sets of spring rods 803, the driving disc 804 is located outside the multiple sets of spring rods 803, and multiple sets of snap-fitting grooves 805 are provided inside the driving disc 804, and the top of the snap-fitting groove 805 is provided with a chamfer, wherein when the motor 2 accelerates the rotation speed, the pulley 802 connected to its output end will The belt 808 drives the other set of pulleys 802 to rotate rapidly. Therefore, the spring rod 803 installed on one set of 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, so that the length of the spring rod 803 is extended until the spring rod 803 is stuck in the locking groove 805. One end of the locking groove 805 is chamfered to facilitate the entry of the spring rod 803, so that the pulley 802 can drive the driving disk 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, an extrusion wheel 304, a peristaltic tube 305 and a discharge pipe 306. The protective shell 302 is fixedly connected to the main body 1 by the cooperation of 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 groups of extrusion wheels 304. The peristaltic tube 305 is fixedly installed inside the protective shell 302, and the peristaltic tube 305 is located between the extrusion wheel 304 and the protective shell 302. One end of the peristaltic tube 305 is fixedly connected to the connecting tube 4, and the other end of the peristaltic tube 305 is fixedly connected to the discharge pipe 306.

[0043] When the motor 2 is powered, the output end of the motor 2 drives the extraction mechanism 3 to start working. The drive shaft 301 is rotated by the motor 2, and the rotating frame 303 is rotated together with the drive shaft 301. The rotating frame 303 is equipped with multiple sets of squeezing wheels 304. At this time, the squeezing wheels 304 will rotate synchronously with the rotating frame 303, squeezing the peristaltic tube 305. The negative pressure inside the peristaltic tube 305 will extract the body fluid from the patient's body. At this time, the body fluid enters the extraction mechanism 3 through the connecting tube 4, and then enters the discharge pipe 306 through the peristaltic tube 305.

[0044] In the example, the liquid collecting mechanism 5 includes a recovery port 501, a recovery box 502, a baffle 503 and a torsion spring 507. The recovery box 502 is movably connected to the main body 1, and the recovery box 502 is located at the bottom end of the main body 1. The recovery port 501 is opened at the top of the recovery box 502, and the cross-section of the recovery port 501 is wide at the top and narrow at the bottom. One side of the interior of the recovery port 501 is rotatably connected to the baffle 503, and the baffle 503 is elastically connected to the recovery port 501 through the torsion spring 507. The liquid collecting mechanism 5 also includes a liquid collecting box handle 504, liquid collecting box rollers 505 and a slide rail 506. The liquid collecting box handle 504 is fixedly installed on the top of the recovery box 502, and multiple sets of liquid collecting box rollers 505 are fixedly connected to the bottom of the recovery box 502. A slide rail 506 is opened at the bottom end of the main body 1.

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

[0046] In the example, the disinfection mechanism 6 further includes an extraction tube 602 and a fixed 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 fixed head 604. A threaded sleeve is provided on the connecting head at the end of the connecting pipe 4, so that the threaded sleeve can be matched with the external thread of the outer wall of the fixed head 604 to fix the connecting pipe 4 to the fixed head 604, so that the disinfection mechanism 6 is connected to the connecting pipe 4;

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

[0048] When the driving disk 804 rotates, the crank 806 is driven to rotate synchronously, so that the movable sleeve 807 pulls the connecting tube 4. When the crank 806 rotates to the bottom of the driving disk 804, the connecting tube 4 is in a tightened state. At this time, the connecting tube 4 enters the tightening groove 704 of the tightening mechanism 7. The tightened connecting tube 4 is tightly fitted with the movable rod 701, and the tightened connecting tube 4 presses the two sets of movable rollers 702, so that the movable rod 701 tilts the other end of the movable rod 701 through the lever principle, so that the connecting tube 4 is tightened as a whole, and the internal diameter of the connecting tube 4 is deformed. After the connecting tube 4 is tightened, the disinfectant passing through the connecting tube 4 can better disinfect and clean the residual body fluids inside, so that the connecting tube 4 can be thoroughly disinfected.

[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 via a damping shaft. One side of the sampling cup 901 is fixedly connected to the sampling handle 902. A groove matching the size of the test tube 904 is provided inside the sampling cup 901. The test tube 904 is placed inside the sampling cup 901. The sampling mechanism 9 also includes a limit block 903, which is fixedly installed inside the recovery port 501. The limit block 903 has an inclined surface on the top, and the limit block 903 serves to limit the baffle 503.

[0050] The user only needs to push and pull the sampling handle 902 to rotate the sampling cup 901 through the damping shaft at the bottom of the sampling cup 901. After the sampling cup 901 is rotated toward the inside of 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 limit block 903. At this time, the test tube 904 will just stay under the discharge pipe 306. At this time, the body fluid extracted from the patient's body will drip into the test tube 904 along the discharge pipe 306. After obtaining a part of the sample, the user pulls the sampling handle to rotate the sampling cup 901 toward the outside of the main body 1, so that the user can take the test tube 904 conveniently, and then facilitate the user to test the patient's body fluid, and the baffle 503 will be reset under the elastic action of the torsion spring 507.

[0051] The working principle of the present invention is as follows: when in use, the user can first push the handle and the universal wheel to move the main body 1 to any position, push the main body 1 to the side of the patient who needs drainage, and then turn on the power supply to energize the electrical components inside the main body 1;

[0052] At this time, the medical staff first uses the puncture needle to insert it into the position where drainage is required in the patient's body, and fixes the position of the puncture needle and the drainage tube, and then takes out the connecting tube 4, wherein the connecting tube 4 is made of elastic rubber material, and a connector is installed at the end of the connecting tube 4, and the connector is tapered, so after the connector is connected 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, avoiding infection analysis;

[0053] After the connector and the drainage tube are installed, the motor 2 is started and powered. The output end of the motor 2 drives the extraction mechanism 3 to start working, wherein 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 is rotated together with the drive shaft 301. A plurality of extrusion wheels 304 are installed on the rotating frame 303. At this time, the extrusion wheels 304 rotate synchronously with the rotating frame 303.

[0054] When the squeezing wheel 304 rotates along with the rotating frame 303, it squeezes 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 negative pressure inside the peristaltic tube 305 extracts the body fluid from the patient's body. 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 pipe 306, the body fluid falls into the recovery port 501 at the top of the liquid collecting mechanism 5. Since the recovery port 501 has a conical structure with a larger top and a smaller bottom, the body fluid flowing out of the discharge pipe 306 is prevented from falling outside the liquid collecting mechanism 5. The body fluid flows directly into the recovery box 502 through the recovery port 501, thereby achieving the extraction of body fluid from the patient.

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

[0057] When sampling, the user only needs to push and pull the sampling handle 902 to rotate the sampling cup 901 through the damping shaft at the bottom of the sampling cup 901. After the sampling cup 901 is rotated toward the inside of 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 limit block 903. At this time, the test tube 904 will just stay under the discharge pipe 306. At this time, the body fluid extracted from the patient's body will drip into the test tube 904 along the discharge pipe 306. After obtaining a portion of the sample, the user pulls the sampling handle to rotate the sampling cup 901 toward the outside of the main body 1, thereby making it convenient for the user to take the test tube 904 and further 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.

[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 a threaded sleeve is provided on the connector at the end of the connecting tube 4, the threaded sleeve can be matched with the external thread of the outer wall of the fixed head 604 to fix the connecting tube 4 to the fixed 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 inside the disinfection box 601. After the disinfectant 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 starts to be powered on to heat the disinfectant passing 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 liquid collecting mechanism 5. Since the extraction speed of the extraction mechanism 3 is now faster, the disinfectant will be sprayed out of 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 recovery tank 502.

[0061] After the motor 2 accelerates, the pulley 802 connected to its output end drives the other set of pulleys 802 to rotate rapidly through the belt 808. Therefore, the spring rod 803 installed on one set of pulleys 802 overcomes the elastic force of the spring inside the spring rod 803 by centrifugal force under the rapid rotation of the pulley 802, so that the length of the spring rod 803 is extended until the spring rod 803 is stuck in the engaging groove 805. One end of the engaging groove 805 is chamfered to facilitate the entry of the spring rod 803, so that the pulley 802 can drive the driving disk 804 to rotate synchronously.

[0062] When extracting body fluid from the patient, the output end of the motor 2 also drives the pulley 802 to rotate. However, the speed of the motor 2 is not enough to enable the spring rod 803 to overcome the elastic force of the spring inside it. Therefore, the spring rod 803 does not fit into the engagement groove 805, and the driving disc 804 does not rotate synchronously with the pulley 802.

[0063] When the driving disk 804 rotates, the crank 806 is driven to rotate synchronously, so that the movable sleeve 807 pulls the connecting tube 4. When the crank 806 rotates to the bottom of the driving disk 804, the connecting tube 4 is in a taut state.

[0064] At this time, the connecting tube 4 will enter the tightening groove 704 of the tightening mechanism 7. The tightened connecting tube 4 will fit tightly with the movable rod 701, and the tightened connecting tube 4 will press the two sets of movable rollers 702, so that the movable rod 701 will tilt up through the lever principle, so that the entire connecting tube 4 is tightened, and the inner diameter of the connecting tube 4 is deformed.

[0065] After the connecting tube 4 is tightened, the disinfectant passing through the connecting tube 4 can better disinfect and clean the residual body fluid inside, thereby completely disinfecting the connecting tube 4;

[0066] After the crank 806 rotates to the top of the driving disk 804, the connecting tube 4 enters a relaxed state. At this time, the movable rod 701 is reset under the elastic action of the tension spring 703. After that, the connecting tube 4 continuously switches between the tensioned and relaxed states under the rotation of the crank 806. Under the flushing of the disinfectant, it is ensured that there is no residual body fluid inside the connecting tube 4.

[0067] After the disinfection is completed and the drainage device is temporarily not used, the user can open the side door on one side of the main body 1 and pull the collection box handle 504 to pull the recovery box 502 out from the inside of the main body 1. After the waste liquid in the recovery box 502 is processed and the recovery box 502 is disinfected, the collection box roller 505 at the bottom of the recovery box 502 is aligned with the slide rail 506 inside the main body 1, and the recovery box 502 can be placed inside the main body 1.

[0068] The above structure can solve the problem that when the patient's abdominal cavity is washed and abdominal drainage is continued, the drainage device needs to be removed to clean the patient's abdominal cavity, and then the drainage device needs to be disinfected and reassembled before use. Manual disinfection may lead to incomplete disinfection and the risk of infection. In addition, when the patient's experience needs to be tested, the existing drainage device is difficult to sample.
