Description

Technical Field

[0001] This invention relates to the field of abdominal lavage technology, and particularly to an abdominal lavage device. Background Technology

[0002] In laparoscopic surgery, peritoneal irrigation is an indispensable core auxiliary procedure. Its main purpose is to remove pus, inflammatory exudate, and various contaminants from the abdominal cavity, dilute the bacterial load, and reduce toxin absorption, thereby lowering the incidence of postoperative complications such as infection, abdominal adhesions, and abscess recurrence, and creating a clean environment for postoperative healing. It is suitable for various conditions such as purulent peritonitis, abdominal abscess, and gastrointestinal perforation.

[0003] Currently, peritoneal lavage in clinical practice involves simultaneous lavage and evacuation. During lavage, the lavage solution is heated to a temperature close to that of the human body, and then the lavage tubing is connected to a laparoscopic trocar or a special lavage needle to irrigate the abdominal cavity. During evacuation, an electric negative pressure suction device and a drainage tube are used to guide the lavage solution from the abdominal cavity into a disposable negative pressure suction bag or drainage bottle. Normal operation requires frequent coordination between physicians and nurses (e.g., changing the lavage solution and suction bag, adjusting the flow rate of the lavage tubing and the drainage tube, and adjusting the lavage angle, etc.), making the entire peritoneal lavage operation quite cumbersome and labor-intensive.

[0023] This invention proposes an abdominal irrigation device.

[0024] like Figures 1 to 5The abdominal lavage device shown includes a controller, a housing 1, and a drainage lavage tube 5. The housing 1 contains a lavage mechanism, a suction mechanism, and a transport mechanism 3. The lavage mechanism includes a storage tank 12, a first liquid pipe 13, and a first infusion pump 14. The storage tank 12 holds the solution. One end of the first liquid pipe 13 is connected to the storage tank 12, and the other end is connected to the drainage lavage tube 5. The first infusion pump 14 is located within the first liquid pipe 13. The housing 1 also contains an injection space 11, which contains several waste bottles and several test bottles. The transport mechanism 3 is located within the injection space 11. The suction mechanism includes a second liquid pipe 15 and a second infusion pump 16. One end of the second liquid pipe 15 is connected to the drainage lavage tube 5. The other end of the flushing tube 5 and the second liquid tube 15 are connected to a waste bottle or test bottle at a preset position in the injection space 11. The second infusion pump 16 is installed in the second liquid tube 15. The controller is electrically connected to the first infusion pump 14, the second infusion pump 16 and the transport mechanism 3 respectively. The controller is used to control the transport mechanism to send one waste bottle or one test bottle into the preset position each time. The controller is also used to control the first infusion pump 14 and the second infusion pump 16 respectively when the drainage flushing tube 5 is connected to the abdominal cavity to be flushed, so as to drive the solution in the storage tank 12 to flow through the first liquid tube 13 and the drainage flushing tube 5 to flush the abdominal cavity. The flushed solution is then input into the waste bottle or test bottle located in the preset position through the drainage flushing tube 5 and the second liquid tube 15.

[0025] By integrating the flushing and aspiration mechanisms and then using the transport mechanism 3 to move the waste bottle and the test bottle, the collection of drained fluid is automated. Staff only need to judge the amount of solution based on the actual situation of the patient's laparoscopic images, send a sufficient amount of solution into the storage tank 12, and insert the drainage flushing tube 5 into the patient's body. This automates the infusion, aspiration, and bottling processes, reducing the workload of peritoneal cleaning and allowing medical staff to focus more on the patient, thus effectively improving the quality of medical care.

[0026] Specifically, the bottom of the box 1 is equipped with casters with brakes, which makes it easy to move and fix the position of the box 1 according to the actual surgical situation.

[0027] Specifically, waste bottles are used to store solutions discarded after rinsing; test bottles are used to store solutions used for testing. Generally, the number of waste bottles in box 1 is higher than the number of test bottles.

[0028] Specifically, the controller is used to acquire a first set flow rate and a second set flow rate, control the flow rate of the first infusion pump 14 according to the first set flow rate, and control the flow rate of the second infusion pump 16 according to the second set flow rate; the first infusion pump 14 and the second infusion pump 16 are started according to the operation information. Both the first set flow rate and the second set flow rate are manually input information.

[0029] Specifically, a flow sensor is installed in the second liquid pipe 15. The flow sensor is electrically connected to the controller. The flow sensor is used to detect the real-time flow of the second liquid pipe 15 and send it to the controller.

[0030] The drainage and flushing tube 5 includes a main pipe 51, an inlet pipe 52, and an outlet pipe 53. The inlet pipe 52 and the outlet pipe 53 are both located inside the main pipe 51. The inlet pipe 52, the outlet pipe 53, and the main pipe 51 are arranged in parallel. One end of the main pipe 51 is respectively opened with an outlet 55 and a suction port 54. One end of the inlet pipe 52 is connected to the outlet 55, and the other end of the inlet pipe 52 is connected to the end of the first liquid pipe 13 away from the liquid storage tank 12. One end of the outlet pipe 53 is connected to the suction port 54, and the other end of the outlet pipe 53 is connected to the end of the second liquid pipe 15 away from the preset position.

[0031] Specifically, the inlet pipe 52 and the first liquid pipe 13, as well as the outlet pipe 53 and the second liquid pipe 15, are all connected by connecting hoses, which facilitates the normal use of the drainage and flushing pipe 5.

[0032] Specifically, the end of the main pipe 51 away from the first liquid pipe 13 is a closed end, and the suction port 54 is located at the closed end; the outlet 55 includes multiple openings, and each opening is located on the side wall of the main pipe 51. The openings are arranged sequentially at intervals along the length of the main pipe 51, which can effectively increase the rinsing area.

[0033] A receiving basket 17 is provided on the outside of the housing 1, and one side of the filling space 11 is connected to the receiving basket 17. A transport channel 2 is provided in the filling space 11, and one end of the transport channel 2 is connected to the receiving basket 17. Each waste liquid bottle and each test bottle is located at the end of the transport channel 2 away from the receiving basket 17. A preset position is located within the transport channel 2. A transport mechanism 3 is located above the transport channel 2 and is used to drive the waste liquid bottles or test bottles to move along the extension direction of the transport channel 2. The transport mechanism 3 moves each waste liquid bottle and each test bottle through the transport channel 2, and the arrangement of the transport channel 2 ensures the accuracy of the movement path of each waste liquid bottle and each test bottle. The receiving basket 17 facilitates the unified collection of each waste liquid bottle and each test bottle after filling with liquid.

[0034] The transport channel 2 is provided with a first slide 21, a second slide 22 and a third slide 23 respectively. One end of the first slide 21 is connected to the receiving basket 17. The end of the first slide 21 away from the receiving basket 17 is connected to one end of the second slide 22 and one end of the third slide 23 respectively. The second slide 22 and the third slide 23 are symmetrically arranged along the first slide 21. The third slide 23 is used to hold a number of waste liquid bottles. The second slide 22 is used to hold a number of test bottles. The preset position is located at the point where the first slide 21 is connected to the second slide 22 and the third slide 23 respectively.

[0035] Specifically, limiting blocks 24 are provided at the end of the second slide 22 away from the first slide 21 and at the end of the third slide 23 away from the first slide 21, which facilitates the arrangement and alignment of each waste liquid bottle and each test bottle.

[0036] Specifically, a loading port is provided on the outer wall of the housing 1, located on the side of the housing 1 opposite to the receiving basket 17. This facilitates medical personnel in feeding waste bottles and test bottles into the injection space 11.

[0037] The transport mechanism 3 includes a track 31, an electrically controlled slide 32, and a driver. The track 31 is positioned above the first slide 21, and the first slide 21 and the track 31 are arranged parallel to each other. The extension path of the track 31 passes between the second slide 22 and the third slide 23. The electrically controlled slide 32 is slidably connected to the track 31. The driver is located on the side of the electrically controlled slide 32 away from the track 31. The electrically controlled slide 32 is used to drive the driver to slide along the slide rail. The controller is electrically connected to the driver and the electrically controlled slide 32 respectively. The controller is used to control the driver and the electrically controlled slide 32 according to the start and sampling commands respectively, so as to send one of the test bottles in the second slide 22 or one of the waste liquid bottles in the third slide 23 into the preset position. When the controller receives the start information, the electronically controlled slide 32 slides along the track 31 and, through the driver, sequentially sends the waste liquid bottle closest to the preset position in the second slide 22 into the preset position; when the controller receives the sampling command, after the current waste liquid bottle or the current test bottle has finished being filled, the test bottle closest to the preset position in the third slide 22 is sent into the preset position.

[0038] Specifically, both the startup information and the sampling instructions are manually entered.

[0039] The driver includes a first mounting base 33, a servo motor, a first limiting rod 35, and a second limiting rod 36. The first mounting base 33 is located on the side of the electrically controlled slide 32 away from the track 31, and the servo motor is located on the side of the first mounting base 33 away from the receiving basket 17. One end of the first limiting rod 35 is connected to the second limiting rod 36, and the first limiting rod 35 is perpendicular to the second limiting rod 36 and parallel to the track 31. The output end of the servo motor passes through the first mounting base 33 and drives the second limiting rod 36 to the side near the first mounting base 33. The controller is electrically connected to the servo motor and is used to control the servo motor when the motor is in operation. When the control slide 32 drives the second limit rod 36 to the working point of the waste liquid bottle or the detection bottle to be moved, it controls the servo motor to drive the second limit rod 36 to rotate to a horizontal state, and rotates the second limit rod 36 to a position behind the waste liquid bottle or the detection bottle to be moved. The controller is used to control the servo motor to drive the second limit rod 36 to rotate to a vertical state when the control slide 32 drives the second limit rod 36 to send the waste liquid bottle or the detection bottle to be moved to the preset position, and then controls the control slide to drive the second limit rod 36 in the vertical state to move to the working point of the next waste liquid bottle or the next detection bottle to be moved. The servo motor drives the second limit rod 36 to rotate according to the working state of the second limit rod 36. When the second limit rod 36 pushes the waste liquid bottle or the detection bottle, the second limit rod 36 is in a horizontal state; when the second limit rod 36 does not push the waste liquid bottle or the detection bottle, the second limit rod 36 is in a vertical state, to avoid the second limit rod 36 from accidentally colliding with the waste liquid bottle or the detection bottle during the displacement process. When the second limiting rod 36 pushes the waste liquid bottle or the test bottle to be moved into the preset position, the first limiting rod 35 can play a lateral auxiliary limiting function to ensure that the waste liquid bottle or the test bottle to be moved enters the preset position.

[0040] Specifically, a first color layer is provided at the mouth of the waste liquid bottle, and a second color layer is provided at the mouth of the test bottle. A camera 18 is also installed within the injection space 11, and a controller is electrically connected to the camera 18. The camera 18 acquires identification images of the second slide 22 and the third slide 23 within the injection space 11 and sends them to the controller. The controller divides the identification images into a first region including the third slide 23 and a second region including the second slide. The controller identifies the number of each first color layer within the first region. When the number of each first color layer is less than or equal to a first set data, the controller issues first supplementary information. The controller also identifies the number of each second color layer within the second region. When the number of each second color layer is less than or equal to a second set data, the controller issues second supplementary information. By acquiring images within the injection space 11 through the camera 18, and based on the fixed shooting position of the camera 18, the identification images are divided into a first region including the third slide 23 and a second region including the second slide 22. Supplementary information is issued by identifying the number of first color layers in the first region and the second feature data in the second region, so that medical personnel can replenish the waste liquid bottle and the test bottle. For example, if the first set data is 2, when the number of the first color layer in the third slide 23 is less than 2, the controller sends a first supplementary message to the staff so that the medical staff can add a sufficient number of waste liquid bottles to the third slide.

[0041] Specifically, both the waste liquid bottle and the test bottle are cylindrical flexible bottles of the same size. The first and second color layers are different colors. The outer wall of the waste liquid bottle is attached to the inner wall of the third slide 23, and the outer wall of the test bottle is attached to the inner wall of the second slide 22.

[0042] Specifically, the controller acquires the working points on track 31 and determines at least one actual position based on the number of each first color layer and each working point. It then controls the driver to sequentially enter each actual position according to the distance of the electronically controlled slide from the nearest preset position, driving the second limit rod 36 to rotate horizontally towards the third slide rail 23. This allows the electronically controlled slide, in conjunction with the second limit rod 36, to sequentially deliver the waste liquid bottles corresponding to each actual position into the preset position. The actual positions are the working points determined based on the number of waste liquid bottles in the third slide rail 23, and the number of working points is greater than or equal to the number of actual positions.

[0043] Specifically, the camera 18 is located on the top side of the liquid injection space 11, and the camera 18 and the transport mechanism 3 are spaced apart on their movement paths. The camera 18 is a wide-angle camera, which ensures both the normal operation of the transport mechanism 3 and the shooting effect of the camera 18.

[0044] Each waste liquid bottle is arranged sequentially along the inner limit block 24 of the third slide 23, starting from the limit block 24. The diameter of the waste liquid bottle is determined, allowing us to determine the drop position of the second limit rod 36 between adjacent bottles. Then, based on the angle between the third slide 23 and the track 31, and the length of the track, we can determine the associated drop positions and their corresponding work points. Finally, based on the number of waste liquid bottles (i.e., the number of the first color layer) and each work point, we can determine which work points are the actual locations. Similarly, the drop position of the second limit rod 36 in the second slide 22 is the same as its drop position in the third slide 23.

[0045] The horizontal height of the end of the first slide 21 near the receiving basket 17 is lower than that of the end of the first slide 21 near the second slide 22. A second mounting base 37 is also provided between the second slide 22 and the third slide 23. An electrically controlled telescopic rod 38 and a push plate 34 are respectively provided on the side of the second mounting base 37 facing the first slide 21. The electrically controlled telescopic rod 38 is located between the push plate 34 and the first mounting base 33, and the output end of the electrically controlled telescopic rod 38 is connected to the push plate 34. A controller is electrically connected to the electrically controlled telescopic rod 38. After the waste liquid bottle or test bottle located in the preset position is filled with liquid, the controller controls the electrically controlled telescopic rod 38 to drive the push plate 34 to push the filled waste liquid bottle or test bottle into the first slide 21. The cooperation of the electrically controlled telescopic rod 38 and the push plate 34 sends the filled waste liquid bottle or test bottle into the first slide 21. With the help of the inclined first slide 21, the waste liquid bottle or test bottle slides into the receiving basket 17.

[0046] Specifically, a receiving tank is set in the preset position. The receiving tank can not only facilitate the positioning of the waste liquid bottle or test bottle that enters the preset position, but also ensure the stability of the waste liquid bottle or test bottle when filling it with liquid.

[0047] The test bottle includes a first bottle body and a first rubber sealing layer, the first rubber sealing layer being disposed at the bottle opening of the first bottle body; the waste liquid bottle includes a second bottle body and a second rubber sealing layer, the second rubber sealing layer being disposed at the bottle opening of the second bottle body.

[0048] Specifically, the body color of the first rubber sealing layer is the same as the second color layer, and the body color of the second rubber layer is the same as the first color layer.

[0049] A liquid injection mechanism 4 is also provided between the transport channel 2 and the transport mechanism 3. The liquid injection mechanism 4 includes a linear motor 41, a third mounting base 42, a connecting pipe 43, a needle 44, and a telescopic hose. The linear motor 41 is located on one side of the transport channel 2 and is arranged vertically. The connecting pipe 43 is located above the preset position and is arranged vertically. The output end of the linear motor 41 is connected to the connecting pipe 43 through the third mounting base 42. The needle 44 is located at the end of the connecting pipe 43 near the preset position. One end of the telescopic hose is connected to the end of the connecting pipe 43 away from the needle 44, and the other end of the telescopic hose (not shown in the figure) is connected to the end of the second liquid pipe 15 away from the drainage flushing pipe 5. The controller is electrically connected to the linear motor 41. The controller is used to control the linear motor 41 to drive the needle 44 through the first rubber sealing layer to connect to the first bottle body, or drive the needle 44 through the second rubber sealing layer to connect to the second bottle body, when the waste liquid bottle or the test bottle enters the preset position. The linear motor 41 drives the needle 44 to insert into the waste liquid bottle or test bottle located in the preset position, so that the waste liquid passes through the outlet pipe 53, the second liquid pipe 15, the telescopic hose, the connecting pipe 43 and the needle 44 in sequence and enters the waste liquid bottle or test bottle located in the preset position.

[0050] The liquid injection mechanism is located directly above the preset position, and the movement paths of the liquid injection mechanism and the transport mechanism 3 are spaced apart. This can prevent the second limit rod 36 from contacting the liquid injection mechanism when pushing the waste liquid bottle or test bottle into the receiving tank, thus ensuring the normal operation of the liquid injection mechanism and the transport mechanism 3.

[0051] The work process is as follows: Step 1: Medical staff input the first and second set flow rates into the controller; Step 2: The controller determines the first supplementary information and the second supplementary information based on the recognized image. Step 3: Medical staff replenish the waste liquid bottle according to the first supplementary information, and replenish the test bottle according to the second supplementary information; Step 4: Medical staff input startup information into the controller; Step 5: The controller controls the electronically controlled slide 32 to move the driver to the actual point closest to the preset position, and then controls the servo motor in the driver to drive the second limit rod 36 to rotate to a horizontal state in the direction of the third slide 23; then the electronically controlled slide 32 drives the second limit rod 36 to send the waste liquid bottle closest to the preset position into the receiving tank. Step 6: The controller controls the linear motor 41 to drive the needle to be inserted vertically into the waste liquid bottle, and the controller sends operation information to the first infusion pump 14 and the second infusion pump 16. Step 7: Drive the first infusion pump 14 according to the first set flow rate and drive the second infusion pump 16 according to the second set flow rate. The solution in the storage tank 12 enters the abdominal cavity to be rinsed through the first liquid pipe 13 and the inlet pipe 52, and then enters the waste liquid bottle located in the receiving tank through the outlet pipe 53, the second liquid pipe 15, the telescopic hose, the connecting pipe 43 and the needle 44. Step 8: According to the preset capacity and the second set flow rate, after the waste liquid bottle located at the preset position is filled with liquid, first control the second infusion pump 14 to turn off and stop the infusion, then control the linear motor 41 to drive the needle away from the waste liquid bottle located at the preset position; then the electric telescopic rod 38 drives the push plate 34 to move towards the first slide 21, push the filled waste liquid bottle or test bottle into the first slide 21 and slide it into the receiving basket 17; Specifically, the preset capacity is the capacity of the test bottle or the waste liquid bottle, and the capacity of the test bottle and the waste liquid bottle is the same.

[0052] Step 9: The electrically controlled telescopic rod drives the push plate 34 away from the first slide rail 21 and away from the preset position; the servo motor drives the second limit rod 36 to rotate upward to the vertical position; Step 10: Execute steps 5 to 9 and obtain the real-time flow rate of the second liquid tube until the real-time flow rate is zero, at which point all waste liquid storage and recycling will be completed. When medical staff determine that sampling is needed for testing based on laparoscopy, step 11 is executed, and the medical staff inputs the sampling command to the controller. The controller controls the electronically controlled slide 32 to move the driver to the actual point closest to the preset position. Then, the controller controls the servo motor in the driver to drive the second limit rod 36 to rotate upward to the second slide rail 22 to a horizontal state. Then, the electronically controlled slide 32 drives the second limit rod 36 to send the test bottle closest to the preset position into the receiving groove. After replacing the waste liquid bottle with the test bottle in steps 6 to 9, steps 6 to 9 are executed to complete the sampling operation, and then step 10 is executed.
