Description

Technical Field

[0001] The present invention relates to the field of postoperative body fluid transfer, and more specifically to a postoperative nursing device for hepatobiliary surgery. Background Art

[0002] Hepatobiliary surgery mainly studies hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of the Chinese people. During the recovery care after hepatobiliary surgery, patients need to drain bile, secretions and other body fluids accumulated in the body cavity through drainage tubes to prevent accumulation in the body cavity or surgical field, secondary compression symptoms, infection or tissue damage.

[0003] During the postoperative drainage care process, it is necessary to observe the color of the patient's drainage fluid by colorimetric observation. The Chinese invention patent application CN110251742A discloses a postoperative nursing device for hepatobiliary surgery. By setting a diversion mechanism, drainage fluid of different periods can be stored, which is convenient for nursing staff to observe the drainage fluid and timely judge the patient's postoperative nursing and recovery status;

[0004] Although it is possible to collect drainage fluid from different time periods, this collection method is to collect at fixed intervals within a predetermined time. When the properties of the liquid change, the time period collection method will mix together different liquids that belong to the same time period but are discharged in batches. The liquid may undergo changes in physical or chemical properties during the discharge process, such as density, viscosity, pH value, component concentration, etc. If collected by time period, the liquids in different time periods may have greatly different properties, and these liquids with different properties will still be mixed together, which will cause deviations in the monitoring data. Summary of the invention

When the properties of the liquid change, the time period collection method will mix together different liquids that belong to a time period but are discharged in batches.

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] In the above solution, by setting the timing body fluid collection unit, the body fluid discharged from the drainage tube and entering the conical liquid storage tank through the first pipeline is monitored by the flowmeter, and the flow rate of the body fluid discharged from the drainage tube each time can be obtained. When there is a change in the flow rate, the timing of the drainage tube discharging liquid each time can be known. Then, through the third pump body, the body fluid discharged from the drainage tube and entering the conical liquid storage tank each time can be pumped and discharged into the syringe through the syringe, and then discharged into the sample storage tube through the syringe, so that the liquid discharged each time can be collected separately, which can help the nursing staff analyze the property changes of each batch of discharged liquid more accurately, ensure that the properties of the liquid discharged in each batch are independent, facilitate the analysis of whether there are abnormalities, clearly master the component changes of each liquid discharge, help the doctor make more accurate treatment decisions. At the same time, for the case of intermittent liquid discharge, collecting according to the liquid discharge timing can better reflect the periodicity and volatility of each liquid discharge, help analyze the law of liquid discharge and whether there are abnormal fluctuations, while collecting in time periods often cannot effectively capture this intermittent change, and may smooth the irregular liquid discharge, thus ignoring potential abnormalities.

[0020] By setting the cleaning liquid supply unit and the in-tank scraping unit, the inside of the conical liquid storage tank and the residues adhering to the inner wall can be cleaned, avoiding the residues from being mixed into the subsequent collected body fluid, resulting in data errors or cross-contamination and affecting the analysis results, improving the purity and accuracy of the analysis, reducing data errors. At the same time, cleaning the inside of the conical liquid storage tank and the residues adhering to the inner wall can keep the inside of the container unobstructed, ensure the smooth discharge of the body fluid, and avoid the delay or incomplete discharge of the liquid discharge caused by blockage.

[0021] By setting up a residue cleaning unit, motor 2 is controlled to work and drive the plate to descend, so that the hollow rotating tube can extend between two adjacent columns. While motor 2 drives the hollow rotating tube to rotate, pump body 1 pumps the cleaning liquid in the liquid storage tank into the hollow rotating tube. The cleaning liquid is sprayed out from the nozzle that rotates with the hollow rotating tube to perform all-round flushing of rod body 1, column, scraper blade 1 and scraper blade 2, which helps to remove residues attached to the outer surfaces of rod body 1, column, scraper blade 1 and scraper blade 2. In this way, comprehensive cleaning can be achieved, avoiding cleaning dead corners or missing parts in the conical liquid storage tank, and avoiding pollution or biosafety risks caused by incomplete cleaning of residues in the conical liquid storage tank.

[0048] like Figures 1 to 11As shown, an embodiment of the present invention provides a postoperative care device for hepatobiliary surgery, including a box body 1, a plurality of openings 11 opened on multiple sides of the box body 1, and a plurality of door bodies 12 respectively engaged in the multiple openings 11, an interface 2 for connecting to a drainage tube is fixedly connected to one side of the box body 1, and a timed body fluid collection unit 3 is also connected inside the box body 1.

[0049] The opportunistic body fluid collection unit 3 includes a support plate 31 fixedly connected to the inner wall of the box body 1, a conical liquid storage tank 32 fixedly connected to the inside of the support plate 31, a cover body 321 clamped at the opening 11 of the conical liquid storage tank 32, a flow meter 33 fixedly connected to the upper end of the cover body 321, a pipe 34 connecting the flow meter 33 with the interface 2, a pump body 35 fixedly connected to the lower end of the conical liquid storage tank 32 and connected to the output end of the conical liquid storage tank 32, a three-way pipe 36 fixedly connected to the output end of the pump body 35, a liquid storage box 37 clamped on the inner bottom wall of the box body 1 and connected to one of the pipe openings of the three-way pipe 36, a two-axis movable platform 39 connected to the inner wall of the box body 1, a needle tube 40 fixedly connected to the Y-axis movable end of the two-axis movable platform 39, a pipe 2 38 connecting the needle tube 40 with the other pipe opening of the three-way pipe 36, and a sample liquid storage component 4 connected to the inner wall of the box body 1.

[0050] The sample liquid storage assembly 4 includes a frame 42 slidably connected to the inner wall of the box body 1, an axial driving part 41 connected to the inner bottom wall of the box body 1 and used to drive the frame 42 to move, a rotating adjustment part 43 fixedly connected to the inside of the frame 42, a rotating rod 44 rotatably connected to the inner side wall of the frame 42, a disk 45 fixedly connected to the outside of the rotating rod 44, and a sample storage tube 46 inserted into the inside of the disk 45, and the output shaft of the rotating adjustment part 43 is fixedly connected to one end of the rotating rod 44.

[0051] By adopting the above technical solution, one end of the drainage tube is connected to the interface 2, and the two-axis mobile platform 39 can drive the needle tube 40 to move up and down (Z-axis movement) and forward and backward (Y-axis movement). After the needle tube 40 is adjusted to a suitable position, the axial driving part 41 (an axial displacement driving mechanism composed of a servo motor, a screw rod, etc., used to drive the frame 1 42 to move in the X-axis direction, which belongs to a mature existing technology and is not repeated here) drives the frame 1 42 to move in the X-axis direction, so that the sample storage tube 46 can be located directly below the needle tube 40. When the body fluid is discharged from the patient's body and flows in the drainage tube, the body fluid is discharged from the drainage tube and enters the pipe 1 34, and is discharged from the pipe 1 34 through the flow meter 33 (which can be When a flow meter suitable for low flow rate and intermittent discharge is selected, such as a turbine flow meter or an ultrasonic flow meter, which can provide relatively stable measurement even when the flow rate changes greatly and is a mature existing technology and will not be described in detail here, the flow meter 33 can monitor the flow change of the body fluid. The flow meter 33 must be equipped with a data acquisition system (a data acquisition module composed of chips, circuit boards, etc. When the flow fluctuates (such as when the discharge starts or stops), the flow meter 33 outputs data to the system, and the system can record these fluctuations and generate corresponding data. For example, the data of the flow meter 33 can be analyzed in combination with the timestamp of each discharge to confirm the timing and volume of each discharge.

[0052] This method can provide detailed drainage volume and cycle data to help determine whether the drainage is normal. Chips, circuit boards, etc. all belong to mature existing technologies and will not be elaborated here. Body fluid enters the conical liquid storage tank 32 through the flowmeter 33. When the pump body three 35 operates, it can pump out the body fluid in the conical liquid storage tank 32 and pump it into the pipeline two 38. The body fluid is discharged from the pipeline two 38 and enters the syringe 40. At this time, the two-axis moving platform 39 can drive the syringe 40 to move downward and make the syringe 40 enter the sample storage tube 46. The body fluid is discharged from the syringe 40 and stored in the sample storage tube 46. After the drainage is completed, the two-axis moving platform 39 drives the syringe 40 to rise and withdraw it from the sample storage tube 46. At this time, the rotation adjustment part 43 (a mechanism composed of a servo motor, gear transmission, etc. for driving the rotating rod 44 to rotate. This driving method belongs to a mature driving method and will not be elaborated here) drives the rotating rod 44 to rotate, drives the disc body 45 to rotate, moves another adjacent empty sample storage tube 46 to directly below the syringe 40 and waits for the next drainage action. When all the sample storage tubes 46 on a disc body 45 are filled with liquid, the two-axis moving platform 39 adjusts the height of the syringe 40 to move it above the other disc bodies 45. It should be noted here that each position for placing the sample storage tube 46 on the disc body 45 is sequentially marked. This can facilitate the recording of each drainage storage. (When the flowmeter 33 detects the body fluid discharged from the drainage tube, the data acquisition system records the drainage time. At the same time, since each disc body 45 is marked, body fluids of different batches are sequentially discharged into the sample storage tubes 46 at different marked positions. Since the marks are also in sequence, the data acquisition system can not only record the drainage time but also record the mark of each drainage. This is convenient for the nursing staff to know the drainage time of the body fluid in the sample storage tube 46 at this position by retrieving the data of the data acquisition system when observing or detecting the body fluid in the sample storage tube 46). Therefore, the timing body fluid collection unit 3 can collect each discharged liquid separately, which can help the nursing staff more accurately analyze the property changes of each batch of drained fluid, ensure that the properties of each batch of discharged fluid are independent, facilitate the analysis of whether there are abnormalities, clearly master the component changes of each drainage, help the doctor make more accurate treatment decisions. At the same time, for the case of intermittent drainage, collecting at the drainage timing can better reflect the periodicity and volatility of each drainage, help analyze the law of liquid discharge and whether there are abnormal fluctuations (which can be analyzed by analyzing the drainage time interval and drainage law).

[0058] By adopting the above technical scheme, each time the liquid is discharged and the pump body 35 draws the body fluid from the conical liquid storage tank 32, the pump body 1 54 can pump the cleaning liquid in the liquid storage tank 55 into the rotary joint 52, and the cleaning liquid enters the hollow rotating tube 532 from the rotary joint 52 and is sprayed out from the nozzle 534. At the same time, the motor 1 678 can drive the connecting part 676, the plug block 675 and the rotating seat 674 to rotate. The rotation of the rotating seat 674 can drive the rod body 1 61 and the multiple columns 62 to rotate. When the multiple columns 62 rotate, the body fluid adhered to the inner wall of the conical liquid storage tank 32 is scraped off by the scraper blade 1 63 and the scraper blade 2 645 respectively. At the same time, when the rotating seat 674 rotates, the inclined top block 2 6741 on one side of the rotating seat 674 can contact the inclined top block 1 322, and the inclined top blocks The surface cooperation enables the rotating seat 674 to move along the rod body 2 671 in the direction of the spring 2 673. When the rotating seat 674 rises and squeezes the spring 2 673, it also moves outside the plug 675. The rise of the rotating seat 674 can also drive the rod body 1 61 and multiple columns 62 to rise. When the multiple columns 62 located in the conical end area of ​​the conical liquid storage tank 32 rise, the distance between the multiple columns 62 and the inner wall of the conical end area of ​​the conical liquid storage tank 32 becomes larger. At this time, the spring 1 643 can push the sleeve 644 to move in the direction of the scraper blade 2 645, so that the scraper blade 2 645 moves toward the inner wall of the conical end area of ​​the conical liquid storage tank 32, so that the scraper blade 2 645 can be close to the inner wall of the conical end area of ​​the conical liquid storage tank 32, thereby achieving complete cleaning of the inner wall of the conical end area of ​​the conical liquid storage tank 32.

[0059] After cleaning, the cleaning liquid can be pumped into the three-way pipe 36 by the pump body 35. The connection between the three-way pipe 36 and the pipeline 2 38 and the liquid storage tank 1 37 must be provided with valves. When the valve at the connection between the three-way pipe 36 and the liquid storage tank 1 37 is opened, the cleaning liquid after cleaning can be discharged into the liquid storage tank 1 37. When the valve at the connection between the three-way pipe 36 and the pipeline 2 38 is opened, the cleaning liquid after cleaning can enter the pipeline 2 38 and be discharged from the needle tube 40, so as to clean the inside of the pipeline 2 38 and the needle tube 40. Some special valves for storing cleaning liquid can be provided on the tray 45. The sample storage tube 46 can control the valve through the circuit board, which is also a mature existing technology and will not be described here. By cleaning the residues inside the conical liquid storage tank 32 and adhering to the inner wall, it is prevented that the residues may be mixed into the body fluids collected subsequently, causing data errors or cross contamination, affecting the analysis results, improving the purity and accuracy of the analysis, reducing data errors, and cleaning the residues inside the conical liquid storage tank 32 and adhering to the inner wall at the same time, it can keep the inside of the container unobstructed, ensure that the body fluids can be discharged smoothly, and avoid drainage delays or incomplete discharge caused by blockage.

[0060] like Figure 2 , Figure 4 and Fig. 9 As shown, one end of the plate body 51 is slidably connected to the inner wall of the box body 1, and a residual cleaning unit 7 is also connected to the inside of the box body 1, and the residual cleaning unit 7 includes a screw rod 71 screwed inside the plate body 51 and rotatably connected to the inner wall of the box body 1 at both ends, a guide rod 72 movably inserted inside the plate body 51 and fixedly connected to the inner wall of the box body 1 at both ends, a bracket 2 73 integrally formed on one side of the plate body 51, a motor 2 74 fixedly connected to one side of the bracket 2 73, a gear 2 76 rotatably connected to one side of the plate body 51 and fixedly connected to the outside of the inner tube of the rotary joint 52, a gear 1 75 rotatably connected to one side of the plate body 51 and fixedly connected to the output shaft of the motor 2 74, and the gear 1 75 is meshed with the gear 2 76, the rotary joint 52 is fixedly connected to one side of the bracket 2 73, and a motor 3 77 is fixedly connected to the upper end of the box body 1, and the output shaft of the motor 3 77 passes through the box body 1 and is fixedly connected to one end of the screw rod 71.

[0061] By adopting the above technical solution, after the driving component 67 drives the telescopic scraper 64 to scrape and clean the inner wall of the conical liquid storage tank 32, the driving component 67 drives the rod body 1 61 and the multiple columns 62 to rotate and reset, and then the motor 3 77 works to drive the screw rod 71 to rotate, and the rotation of the screw rod 71 can drive the plate body 51 to move. When the screw rod 71 rotates to drive the plate body 51 to descend, the plate body 51 descends to make the hollow fixed tube 531 extend into the interior of the conical liquid storage tank 32, and at the same time, the hollow rotating tube 532 extends between two adjacent columns 62, and the motor 2 74 works to drive the gear 1 75 and the gear 2 76 to rotate, and the gear 2 76 rotates to drive the inner tube of the rotary joint 52 and the hollow rotating tube 532 Rotate, at this time, the pump body 54 can pump the cleaning liquid in the liquid storage tank 55 into the rotary joint 52, and the cleaning liquid enters the hollow rotating tube 532 from the rotary joint 52, and is sprayed out from the nozzle 534 that rotates with the rotation of the hollow rotating tube 532, so as to perform all-round flushing on the rod body 1 61, the column 62, the scraper blade 1 63 and the scraper blade 2 645, which helps to remove the residues attached to the outer surfaces of the rod body 1 61, the column 62, the scraper blade 1 63 and the scraper blade 2 645. In this way, comprehensive cleaning can be achieved, avoiding the existence of cleaning dead corners or missing parts in the conical liquid storage tank 32, and avoiding pollution or biosafety risks caused by incomplete cleaning of the residues in the conical liquid storage tank 32.

[0062] like Figure 2 and Fig.10 As shown, the outer surface of the conical liquid storage tank 32 is fixedly connected to an ultrasonic transducer 9, the inner wall of the box body 1 is fixedly connected to an ultrasonic generator 8, and the ultrasonic generator 8 is connected to the ultrasonic transducer 9, one side of the ultrasonic transducer 9 is connected to a conductive frame 10, and the other end of the conductive frame 10 is sleeved on the outside of the second pipe 38, and the second pipe 38 includes a steel wire 382 (the steel wire 382 forms a spiral shape in the hose, which is usually used for high-pressure transportation and applications requiring strong tensile strength, and is suitable for occasions with high flexibility and pressure resistance requirements), an inner layer 383 that wraps the steel wire 382 (the inner layer 383 is the part of the pipeline that is in direct contact with the transportation medium, mainly To play the role of corrosion resistance, wear resistance, and prevention of liquid or gas leakage, the optional materials are rubber, plastic, TPU, etc.), the outer layer 381 wrapped outside the inner layer 383 (the outer layer 381 mainly provides resistance to wear, environmental pollution, UV radiation and chemicals. It protects the steel wire 382 and the inner layer 383 from damage by the external environment and increases the service life of the hose. The optional materials are rubber, polyurethane, polyester or nylon braiding, etc.), and one end of the steel wire 382 passes through the inner layer 383 and the outer layer 381 and is fixedly connected to the conductive frame 10, and the steel wire 382 passes through the inner layer 383 and extends into the cavity inside the inner layer 383.

[0063] By adopting the above technical solution, the ultrasonic generating part 8 generates a high-frequency electrical signal and outputs it to the ultrasonic transducer part 9. The ultrasonic transducer part 9 converts the electrical signal into mechanical vibrations. These vibrations are transmitted to the conical liquid storage tank 32 to form ultrasonic waves. When cleaning the conical liquid storage tank 32, the ultrasonic waves can improve the cleaning effect. At the same time, the ultrasonic waves can also be transmitted to the steel wire 382 inside the pipe 2 38 through the conductive frame 10. The ultrasonic waves transmitted through the steel wire 382 will generate high-frequency vibrations and tiny cavitation effects in the pipe. This effect can effectively prevent particles or sediments in body fluids from adhering to the inner wall of the pipe. When the cleaning liquid flows in the pipe 2 38, the cleaning efficiency of the cleaning liquid on the inside of the pipe 2 38 can also be improved, especially for sediments with strong adhesion and thin films on the pipe wall. At the same time, continuous vibration can keep the inside of the pipe clean, reduce the risk of blockage caused by long-term accumulation, and reduce the adhesion between the liquid and the pipe wall, so that the liquid flows more smoothly in the pipe, thereby improving the transportation efficiency.

[0064] like Figure 2 , Figure 4 and Figure 5 As shown, a feed trough is provided inside the cover body 321, and one end of the flow meter 33 is connected to the feed trough, a viscosity sensor 13 is fixedly connected to the inner wall of the feed trough, a liquid storage tank 15 is fixedly connected to one side of the support plate 31, and a pump body 16 is fixedly connected to one side of the outer surface of the liquid storage tank 15, a liquid discharge head 14 is fixedly connected to the cover body 321, and the output end of the pump body 16 is connected to the liquid discharge head 14 through a pipeline, and the input end of the pump body 16 extends into the liquid storage tank 15.

[0065] By adopting the above technical solution, the viscosity of the body fluid discharged from the pipe 1 34 and about to fall into the conical liquid storage tank 32 can be detected by the viscosity sensor 13. By detecting the viscosity of the body fluid, when the viscosity of the body fluid is high, the pump body 16 can pump the diluent in the liquid storage tank 15 (physiological saline can be used, which is compatible with hepatobiliary fluid or peritoneal fluid, can dilute the liquid, reduce its viscosity, and has little effect on the properties of hepatobiliary fluid or peritoneal fluid, and will not interfere with subsequent liquid component detection) into the conical liquid storage tank 32, thereby diluting the body fluid, avoiding blockage when the body fluid is transported through the pipe 2 38, and improving the stability and continuity of the body fluid transportation.

[0066] The workflow of the technical solution provided by the present invention is as follows:

[0067] One end of the drainage tube is connected to the interface 2, and the two-axis moving platform 39 can drive the needle tube 40 to move up and down to move it to a suitable position. The axial driving part 41 drives the frame 1 42 to move in the X-axis direction, so that the sample storage tube 46 can be located directly below the needle tube 40. The body fluid is discharged from the drainage tube and enters the pipeline 1 34. When it is discharged from the pipeline 1 34 and passes through the flow meter 33, the flow meter 33 can monitor the flow change of the body fluid. The body fluid enters the conical liquid storage tank 32 through the flow meter 33, and the pump body 35 can work to pump the body fluid in the conical liquid storage tank 32. The body fluid is discharged from the second pipe 38 and enters the needle tube 40. At this time, the two-axis moving platform 39 can drive the needle tube 40 to move downward and make the needle tube 40 enter the sample storage tube 46. The body fluid is discharged from the needle tube 40 and stored in the sample storage tube 46. After the discharge is completed, the two-axis moving platform 39 drives the needle tube 40 to rise and draw it out of the sample storage tube 46. The rotating adjustment part 43 drives the rotating rod 44 to rotate, drives the disk 45 to rotate, and moves another adjacent empty sample storage tube 46 to the bottom of the needle tube 40 and waits for the next discharge action.

[0068] After each discharge and pump body 35 pumps the body fluid out of the conical liquid storage tank 32, pump body 1 54 can pump the cleaning fluid in the liquid storage tank 55 into the rotary joint 52, and the cleaning fluid enters the hollow rotating tube 532 from the rotary joint 52. At the same time, the driving component 67 drives the telescopic scraper 64 to scrape and clean the inner wall of the conical liquid storage tank 32. After the driving component 67 drives the telescopic scraper 64 to scrape and clean the inner wall of the conical liquid storage tank 32, the driving component 67 drives The rod body 1 61 and the plurality of columns 62 rotate and reset, and then the motor 3 77 works to drive the screw rod 71 to rotate, and the rotation of the screw rod 71 can drive the plate body 51 to move. When the screw rod 71 rotates and drives the plate body 51 to descend, the plate body 51 descends to make the hollow fixed tube 531 extend into the interior of the conical liquid storage tank 32, and at the same time, the hollow rotating tube 532 extends between two adjacent columns 62, and the motor 2 74 works to drive the gear 1 75 and the gear 2 76 to rotate, and the gear 2 76 rotates to drive the rotation The inner tube of the joint 52 and the hollow rotating tube 532 rotate, and at this time, the pump body 1 54 can pump the cleaning liquid in the liquid storage tank 55 into the rotating joint 52, and the cleaning liquid enters the hollow rotating tube 532 from the rotating joint 52, and is sprayed out from the nozzle 534 that rotates with the rotation of the hollow rotating tube 532, and the rod body 1 61, the column 62, the scraper 1 63 and the scraper 2 645 are washed in all directions, and the cleaning liquid in the conical liquid storage tank 32 can be cleaned by the pump body The three 35 is drawn into the three-way pipe 36, and the connection between the three-way pipe 36 and the pipe 2 38 and the liquid storage tank 1 37 must be provided with a valve. When the valve at the connection between the three-way pipe 36 and the liquid storage tank 1 37 is opened, the cleaning liquid after cleaning can be discharged into the liquid storage tank 1 37; when the valve at the connection between the three-way pipe 36 and the pipe 2 38 is opened, the cleaning liquid after cleaning can enter the pipe 2 38 and be discharged from the needle tube 40, thereby cleaning the pipe 2 38 and the inside of the needle tube 40.
