Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a multifunctional pleuroperitoneal fluid drainage device for treating lung injury and a system thereof. BACKGROUND

[0002] Lung injury can be caused by trauma, infection and inflammation, etc., and trauma, infection (such as pneumonia, empyema), inflammation (such as ARDS) or hypoproteinemia can cause an increase in capillary permeability, and the inflammatory response after injury can cause an increase in pleural / abdominal effusion, forming pleural effusion or ascites. These effusions can occupy the chest cavity space, limit alveolar expansion, cause atelectasis and ventilation / blood flow imbalance, and increase the risk of respiratory failure.

[0003] In the prior art, drainage treatment can reduce the pressure on the lung tissue, improve respiratory function, and at the same time reduce the risk of lung infection by reducing the environment for bacterial proliferation. During the drainage process, the main reason for inaccurate control of the suction pressure or flow rate is inaccurate negative pressure parameter setting, and the second reason is that the nature of the effusion affects the suction process, such as the fact that infected effusion contains a large number of white blood cells, bacteria and inflammatory factors, and is easy to form purulent viscous liquid, which is prone to blockage, the flow resistance during the suction process is large, high negative pressure and long time suction are required, which leads to difficult pressure control; and fibrous protein deposition forms interstitial separation, causing multiple interstitial spaces between adjacent effusions, which causes the effusion in a specific interstitial space to be difficult to drain, other interstitial spaces to be normally drained, pressure system fluctuations to be affected, and negative pressure suction control difficulty to be increased.

[0004] Therefore, the present application provides a pleuroperitoneal fluid drainage device and system capable of maintaining stable suction pressure to reduce the risk of drainage pipeline blockage and continuously extract effusion in the patient's chest cavity. SUMMARY

[0005] To solve the above problems, the present application provides a multifunctional pleuroperitoneal fluid drainage device for treating lung injury and a system thereof, which can reduce the risk of drainage pipeline blockage, maintain stable suction pressure, and continuously extract effusion in the patient's chest cavity.

[0006] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows: a multifunctional pleuroperitoneal fluid drainage device for treating lung injury, comprising a drainage tube, a plurality of negative pressure tubes communicated with the drainage tube, a negative pressure machine for generating negative pressure suction force communicated with the end of the negative pressure tube away from the drainage tube, a plurality of flushing tubes for conveying flushing liquid communicated with the drainage tube, and a peristaltic mechanism for externally pushing the drainage tube, the peristaltic mechanism comprising a fixed groove body and a pushing wheel, the drainage tube being located in the fixed groove body, and the pushing wheel abutting against the drainage tube.

[0007] The fixed groove body is provided with an opening and closing mechanism near one side of the drainage tube, and the opening and closing mechanism is used for connecting the flushing pipe with the drainage tube based on the pressing of the pushing wheel.

[0008] Further, the peristaltic mechanism comprises a plurality of first rotating discs and second rotating discs, the first rotating discs and the second rotating discs are coaxially connected with driving members, the outer walls of the first rotating discs and the second rotating discs are fixedly connected with support rods, the pushing wheel is in rotational cooperation with the support rods, and the pushing wheel is located between the fixed groove body and the support rods.

[0014] When the extension block is located in the drainage tube, the torsional spring is in a natural stretching state, the shielding block closes the flushing pipe, and the closing plate is located between the shielding block and the branch pipe; when the extension block is pushed by the pushing wheel and located in the conversion chamber, the torsional spring is in a compressed state, and the shielding block and the closing plate are separated from the conversion chamber.

[0015] Further, one end of the extension block away from the center axis is provided with a matching hole, the conversion chamber is provided with a fixing pin for fixing the extension block, one end of the fixing pin away from the conversion chamber is fixedly connected with an electric push rod, and the electric push rod is electrically connected with a control panel.

If the real-time flow rate is inconsistent with the standard flow rate, the adjustment abnormal instruction is recorded. If the turbidity is less than the blockage value, the standby instruction is sent to the driving part corresponding to the first rotating disc and the second rotating disc.

[0043] The drainage tube 1 is in an S shape, a groove wheel (not shown in the figure) is coaxially and fixedly connected to the top of the first rotating disc 5, adjacent groove wheels are rotationally connected through chains, and the corresponding driving member of the second rotating disc 51 is used for converting the rotating direction of the second rotating disc 51.

[0044] The side of the fixed groove body 4 close to the drainage tube 1 is provided with an opening and closing mechanism, the opening and closing mechanism is used for making the flushing pipe 2 communicate with the drainage tube 1 based on the pressing of the pushing wheel 53. The opening and closing mechanism comprises a conversion chamber 41 fixedly connected with the fixed groove body 4, the conversion chamber 41 is respectively communicated with the drainage tube 1, the flushing pipe 2 and the negative pressure pipe 3; a center shaft 22 is rotationally matched in the center of the conversion chamber 41, a torsional spring is sleeved on the center shaft 22, one end of the torsional spring is fixedly connected with the conversion chamber 41. The other end of the torsional spring is fixedly connected with the center shaft 22, one side of the outer wall of the center shaft 22 is fixedly connected with a shielding block 21, the other side of the outer wall of the center shaft 22 is fixedly connected with an extension block 23, and the extension block 23 is located in the drainage tube 1; a sliding groove is opened in the shielding block 21, a closing plate 24 is slidably matched in the sliding groove, one end of the sliding groove away from the closing plate 24 is communicated with the atmosphere, the side of the closing plate 24 close to the flushing pipe 2 of the conversion chamber 41 is communicated with a branch pipe 31, one end of the branch pipe 31 away from the conversion chamber 41 is communicated with the negative pressure pipe 3, a one-way valve is communicated in the branch pipe 31, and the one-way valve can only make the air in the branch pipe 31 flow from the conversion chamber 41 to the inside of the negative pressure pipe 3; when the extension block 23 is located in the drainage tube 1, the torsional spring is in a natural stretching state, the shielding block 21 closes the flushing pipe 2, and the closing plate 24 is located between the shielding block 21 and the branch pipe 31; when the extension block 23 is pushed by the pushing wheel 53 and located in the conversion chamber 41, the torsional spring is in a compressed state, and the shielding block 21 and the closing plate 24 are separated from the conversion chamber 41.

[0045] The specific implementation process is as follows:

[0046] Firstly, the present scheme makes up for the phenomenon of reduced flow rate or blockage caused by the viscous adhesion and effusion in the drainage tube 1 by the double push of negative pressure suction and peristalsis mechanism, so as to ensure the stability of the control of the flow rate in the drainage tube 1.

[0047] During the movement of the first rotating disc 5 and the second rotating disc 51, the first rotating disc 5 and the second rotating disc 51 are driven to rotate by the driving members respectively, the first rotating disc 5 and the second rotating disc 51 drive the pushing wheel 53 to extrude the drainage tube 1 in the fixed groove body 4 through the supporting rod 52, the pushing wheel 53 extrudes and pushes the deformable drainage tube 1, so that the impurities possibly attached to the inner wall of the drainage tube 1 or the sediments retained therein are moved, thereby reducing the possible blockage of the drainage tube 1, so as to facilitate the subsequent stable control of the flow rate of the effusion in the drainage tube 1. The pushing force in the opposite direction in the drainage tube 1 is formed by the second rotating disc 51, the extrusion in the drainage tube 1 between the first rotating disc 5 and the second rotating disc 51 is counteracted, so as to reduce the possible adhesion of the adhesion in the drainage tube 1, so as to ensure the smoothness of the drainage tube 1.

[0048] At the same time, during the simultaneous rotation of the adjacent first rotating discs 5 through the chain, the drainage tube 1 is extruded and closed by the pushing wheel 53, so that the drainage tube 1 forms a relatively closed conveying section between the adjacent first rotating discs 5, and the direction of rotation of the second rotating disc 51 is controlled subsequently.

[0049] The direction of rotation of the second rotating disc 51 is adjusted by the corresponding driving member of the second rotating disc 51, which can form a liquid pushing force in the opposite direction of the first rotating disc 5 to form a reverse flushing in the drainage tube 1, so as to strengthen the cleaning of the residues on the inner wall of the drainage tube 1, or can form the same direction as the first rotating disc 5 to strengthen the conveying power in the conveying section to push the effusion to move quickly, thereby reducing the possible blockage in the conveying section.

[0050] During the normal conveying of the effusion in the conveying pipe, the blocking block 21 is pushed to abut against the side of the conversion chamber 41 close to the flushing pipe 2 by the elastic force of the torsion spring, at this time, the negative pressure suction force continuously generated in the negative pressure pipe 3 extracts the gap between the blocking block 21 and the conversion chamber 41 through the branch pipe 31, so that the air between the blocking plate 24 in the blocking block 21 and the conversion chamber 41 is continuously reduced, a negative pressure environment is formed between the blocking plate 24 and the conversion chamber 41, and the side of the sliding groove away from the blocking plate 24 is in communication with the atmosphere, the atmospheric pressure is used to press the blocking plate 24 tightly on the conversion chamber 41, so as to achieve the sealing effect of the blocking plate 24 on the flushing pipe 2.

[0051] When the peristaltic mechanism is started, the first rotating disc 5 or the second rotating disc 51 drives the pushing wheel 53 to rotate through the supporting rod 52, so that the pushing wheel 53 extrudes the drainage tube 1 to be attached to the inside of the fixed groove body 4. Since the extension block 23 is located inside the drainage tube 1, when the pushing wheel 53 abuts against the extension block 23, the extension block 23 rotates around the central shaft 22 to drive the shielding block 21 to move away from the conversion chamber 41 and approach the surface of the flushing tube 2, so that the closing plate 24 no longer closes the flushing tube 2, and the flushing liquid in the flushing tube 2 is automatically discharged into the drainage tube 1, thereby reducing the concentration of the accumulated liquid in the drainage tube 1, facilitating the subsequent drainage, and ensuring the smoothness of the pipeline.

[0052] In another embodiment, the end of the extension block 23 away from the central shaft 22 is provided with a matching hole 43, and the conversion chamber 41 is provided with a fixing pin 42 for fixing the extension block 23. The end of the fixing pin 42 away from the conversion chamber 41 is fixedly connected with an electric push rod, and the electric push rod is electrically connected with a control panel (not shown in the figure). When the extension block 23 continuously abuts against the pushing wheel 53 and moves to the farthest end, the fixing pin 42 coincides with the matching hole 43.

[0053] The specific implementation process is as follows: the starting condition of the electric push rod is controlled through the control panel, the electric push rod drives the fixing pin 42 to stretch and retract, the fixing pin 42 is inserted into the inside of the matching hole 43, the extension block 23 is fixed, the communication between the flushing tube 2 and the drainage tube 1 is continuously controlled, the consistency of the accumulated liquid in the drainage tube 1 is continuously adjusted, the smoothness of the drainage tube 1 is ensured, and the normal drainage is facilitated.

[0054] A multifunctional chest and abdominal fluid drainage system for treating lung injury, according to the system of the multifunctional chest and abdominal fluid drainage device for treating lung injury, a flow rate sensor is located in the flushing tube 2, and a turbidity sensor is located in the negative pressure tube 3. The flow rate sensor and the turbidity sensor are electrically connected with the control panel. The flow rate sensor is used to detect the real-time flow rate in the flushing tube 2, and the turbidity sensor is used to detect the turbidity of the accumulated liquid in the negative pressure tube 3.

[0055] The control panel is used to record and store the suction flow rate in the drainage tube 1 at the current time, the corresponding blockage value of the suction flow rate, the standard flow rate corresponding to different blockage values, the standard rotating speed corresponding to the first rotating disc 5 and the second rotating disc 51, compare the turbidity at the current time with the corresponding blockage value, if the turbidity is greater than or equal to the blockage value, obtain the corresponding standard flow rate and standard rotating speed based on the blockage value, send a starting instruction to the corresponding driving member of the first rotating disc 5 and the second rotating disc 51 based on the standard rotating speed, and compare the real-time flow rate with the standard flow rate for consistency. If the real-time flow rate is consistent with the standard flow rate, a normal adjustment instruction is recorded. If the real-time flow rate is inconsistent with the standard flow rate, an abnormal adjustment instruction is recorded. If the turbidity is less than the blockage value, a standby instruction is sent to the corresponding driving member of the first rotating disc 5 and the second rotating disc 51.

[0056] For example, first, by recording the suction flow rate under different flow conditions, while establishing the corresponding blockage value, standard flow and standard speed of different suction flow rates, to provide reference standards for subsequent blockage judgment; then the turbidity sensor detects the turbidity of the current time of the effusion to control the corresponding driving part of the first rotating disc 5 and the second rotating disc 51 to start, and the rotating wheel is used to extrude and push the drainage tube 1, which can reduce the possibility of blockage in the drainage tube 1; then the rotating wheel pushes the extension block 23 to open the flushing pipe 2, so that the flushing liquid in the flushing pipe 2 disperses the effusion in the drainage tube 1, reduces the viscosity of the effusion, and facilitates the subsequent continuous drainage.

[0057] At the same time, by comparing the real-time flow with the standard flow, by adjusting the normal instruction and the abnormal instruction record, the reference basis for subsequent power regulation of the negative pressure machine and regulation of negative pressure drainage is provided, so as to ensure the stability of the control of effusion flow rate in the drainage process.

[0058] In another embodiment, the control panel is also used to mark the turbidity sensor adjustment position based on the distribution position of the first rotating disc 5 or the second rotating disc 51, and the second rotating disc 51 is taken as the center, and the flow direction of the effusion in the drainage tube 1 is followed, wherein the turbidity detected by the turbidity sensor upstream of the second rotating disc 51 is the first comparison value, and the turbidity detected by the turbidity sensor downstream of the second rotating disc 51 is the second comparison value.

[0059] When the turbidity detected by the turbidity sensor upstream of the second rotating disc 51 is greater than or equal to the blockage value, the difference value between the first comparison value and the second comparison value is calculated, and the difference value is compared with the set start value, if the difference value is greater than the start value, the standby instruction is sent to the driving part corresponding to the second rotating disc 51; if the difference value is less than the start value, the reverse rotation instruction is sent to the driving part corresponding to the second rotating disc 51.

[0060] For example, in the process of adjusting the viscosity of the effusion in the drainage tube 1 by the communication of the flushing pipe 2 when the blockage occurs in the drainage tube 1, the first comparison value and the second comparison value corresponding to the adjacent first rotating disc 5 are compared, and the difference value is compared with the start value, to judge whether the flushing liquid discharged by the flushing pipe 2 disperses the effusion, so as to control the driving part corresponding to the second rotating disc 51, to form reverse flushing to strengthen the dispersion of the effusion in the drainage tube 1, thereby ensuring the stability of the subsequent drainage flow rate control.

[0061] The control panel is also used to send normal working instructions to the corresponding driving element of the first rotating disc 5 when the turbidity detected by the corresponding turbidity sensor upstream of the second rotating disc 51 is greater than or equal to the blockage value, and the control panel records the adjustment of normal instructions. If the control panel records the adjustment of abnormal instructions, the power adjustment instruction is sent to the corresponding negative pressure machine of the first rotating disc 5 based on the change value between the real-time flow and the standard flow.

[0062] When the turbidity detected by the corresponding turbidity sensor downstream of the second rotating disc 51 is greater than or equal to the blockage value, and the real-time flow is inconsistent with the standard flow, the real-time flow is compared with the standard flow. If the real-time flow is greater than the standard flow, the reverse rotation instruction is sent to the corresponding driving element of the second rotating disc 51, and the rotation speed of the corresponding driving element of the second rotating disc 51 is adjusted based on the change value between the real-time flow and the standard flow. If the real-time flow is less than the standard flow, the forward rotation instruction is sent to the corresponding driving element of the second rotating disc 51.

[0063] For example, during the discharge of the flushing liquid inside the flushing pipe 2, the negative pressure suction or the pushing wheel 53 has a corresponding influence on the flow rate inside the drainage tube 1, and the power of the corresponding negative pressure suction of the first rotating disc 5 is adjusted to maintain the stability of the flow rate inside the drainage tube 1, thereby ensuring the stability of the flow rate of the effusion discharged by the negative pressure pipe 3, and the influence of the flow rate of the effusion inside the drainage tube 1 on the subsequent flow rate inside the drainage tube 1.

[0064] For the corresponding turbidity sensor downstream of the second rotating disc 51, the real-time flow is compared with the standard flow, and the rotation direction of the second rotating disc 51 is controlled. When the second rotating disc 51 is in reverse rotation, the flow rate of the effusion inside the drainage tube 1 is slowed down to ensure the stability of the flow rate of the effusion inside the subsequent negative pressure pipe 3. When the second rotating disc 51 is in forward rotation, the flow rate of the effusion inside the drainage tube 1 is accelerated to ensure that the flow rate of the effusion during the subsequent suction process of the drainage tube 1 and the negative pressure pipe 3 is in a normal state, thereby facilitating the maintenance of the smoothness of the pipeline inside the drainage tube 1.

[0065] In other embodiments, the extension block 23 away from one side of the central shaft 22 is also fixedly connected with a pressure sensor for measuring real-time pressure data when the rotating wheel contacts the extension block 23, and the pressure sensor is electrically connected with the control panel.

[0066] The control panel is used to compare the real-time pressure data with the set rated value. If the real-time pressure data is greater than the rated value, the turbidity of the current position marker corresponding turbidity sensor is obtained, and the turbidity at the current time is compared with the corresponding blockage value. If the turbidity is greater than or equal to the blockage value, the delay start instruction is sent to the electric push rod. If the turbidity is less than the blockage value, the standby instruction is sent to the electric push rod. If the real-time pressure data is less than the rated value, the standby instruction is sent to the electric push rod.

[0067] For example, the contact between the rotating wheel and the extension block 23 is detected by the pressure sensor, and the starting of the electric push rod is controlled based on the current time turbidity and the size of the blockage value, so as to continuously control the continuous opening of the flushing pipe 2, and the accumulated liquid in the drainage pipe 1 is dispersed by the continuous flushing amount in the flushing pipe 2, so as to ensure the smoothness of the drainage pipe 1 and the negative pressure pipe 3, and reduce the influence of the high-viscosity accumulated liquid in the drainage pipe 1 on the drainage process.

[0068] When the turbidity detected by the turbidity sensor upstream of the second rotating disc 51 is greater than or equal to the blockage value, the difference value is less than the starting value, and the real-time pressure data is greater than the rated value, the control panel sends a stop instruction to the driving member corresponding to each first rotating disc 5 and the negative pressure machine, and sends a back-and-forth rotating instruction to the driving member corresponding to the second rotating disc 51.

[0069] For example, by sending a stop instruction to the driving member corresponding to the first rotating disc 5, the drainage pipe 1 is extruded and closed by the driving member, and then by sending a back-and-forth rotating instruction to the driving member corresponding to the second rotating disc 51, the inside of the drainage pipe 1 is flushed back and forth, so as to reduce the generation of attachments or sediments on the inner wall of the drainage pipe 1, thereby facilitating the smoothness of the drainage pipe 1.

Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
