Description

Technical Field

[0001] This invention relates to the field of empyema treatment technology, and more specifically to an empyema treatment device. Background Technology

[0002] Empyema refers to a purulent infection caused by pathogens invading the pleural cavity, resulting in the accumulation of purulent exudate within the cavity. Treatment for empyema typically involves immediate initiation of antibiotics and drainage of the infected pleural effusion. Due to the high incidence of complications and mortality, antibiotic treatment should not be delayed due to diagnostic examinations or effusion drainage. However, empirical treatment often lacks precision, and definitive treatment should be based on results such as pus culture or mNGS. Drainage of the pleural effusion in empyema can effectively control the source of infection. A chest drainage tube is usually placed under ultrasound or CT guidance. If the effusion is large or freely flowing, a blind puncture drainage tube can be placed bedside. However, the drainage tube is easily contaminated by pus and blood. The blockage is caused by fluid or fibrin debris. Under normal circumstances, the pH value in the human pleural cavity is mostly alkaline (around 7.60), while in patients with empyema, the pH value can be lowered (usually less than 7.20) due to the local metabolic activity of pathogens and inflammatory cells. Adjusting the pH value in the pleural cavity (such as intrapleural lavage and drainage with sodium bicarbonate) can effectively shorten the treatment cycle of empyema. If the condition does not improve after the use of antibiotics and closed pleural drainage, it is recommended to administer fibrinolytic agents into the pleural cavity. If the above treatments fail to relieve the condition, thoracoscopic surgery is often required.

[0003] Chest drainage tubes are widely used in the diagnosis and treatment of empyema. Common drainage tubes include traditional silicone tubes, balloon catheters, central venous catheters, pigtail catheters, 16F gastric tubes, abdominal drainage tubes, and even self-made chest drainage tubes. The main functions of these tubes are obtaining empyema specimens, regularly draining and lavaging pleural effusion. Their clinical functions are relatively limited, but they carry the risk of exogenous infection. Some tubes have drawbacks such as numerous complications and susceptibility to blockage. Furthermore, none of them have the function of monitoring intrapleural pH, failing to effectively cover the entire process of empyema development and progression, including diagnosis, precise treatment, efficacy monitoring, and prognostic assessment. This results in a heavy disease burden for empyema patients and cannot effectively improve mortality rates. Therefore, developing a fully functional treatment device for empyema is imperative. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes a treatment device for empyema to solve the above problems.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] The present invention provides a treatment device for empyema, comprising:

[0007] A docking box is provided with a lid that can be axially rotated on its top. A pair of first connectors are symmetrically inserted through the bottom of the docking box with the rotation axis of the lid as the center. Multiple pairs of second connectors are inserted through the lid. The docking box and the lid can be rotated relative to each other so that the inner ends of two first connectors can be connected with the inner ends of any pair of second connectors. Each second connector is provided with a connecting pipe at its outer end.

[0008] The main body has a partition strip in its middle, which divides the interior of the main body into two pipes. One end of the main body is connected to two branch pipes, and the two branch pipes are connected to the outer end of the first connector. The other end of the main body is an insertion end. A monitoring pipeline is provided on the outside of the main body. One end of the monitoring pipeline is located at the insertion end and is equipped with a monitoring probe, and the other end is connected to a pH monitor.

[0009] Furthermore, the second connector is provided with at least three pairs, one of which is a self-cleaning connector, and the other two self-cleaning connectors are respectively connected to a water injection device and a negative pressure suction device via connecting pipes.

[0010] Furthermore, there is a notch between the partition strip and the extension end of the main body. Hinges are rotatably connected to both sides of the port of the extension end. The hinges are connected to the extension end through elastic elements to provide elastic force that allows the two hinges to separate and extend outward. The two hinges can be closed by rotating inward. A control mechanism is provided in the docking box to drive the two hinges to rotate inward and close.

[0011] Furthermore, the partition strip has a traction channel along its length. The control mechanism includes a ring seat, a control sleeve, and a traction rope. The ring seat is installed at the bottom of the inner cavity of the docking box. The top of the ring seat has arc-shaped protrusions on both sides corresponding to the two self-cleaning connectors. The control sleeve is located at the bottom of the box cover, and a control block is slidably inserted into its bottom. Rollers are connected to both sides of the control block by support rods. The rollers are located above the ring seat. A first spring is connected between the control block and the control sleeve to provide elastic force to push the control block so that the rollers abut against the top of the ring seat. The traction rope is located in the traction channel. One end of the rope slides through the bottom of the docking box and connects to the control block. The other end is located at the notch and forks into two support ropes. The two support ropes are respectively connected to the inner sides of the two hinges.

[0012] Furthermore, a limit block is provided on the edge of the hinge, and a sealing plug is provided on the inner side of the hinge.

[0013] Furthermore, the docking box has side openings on both sides, and sealing rings are slidably fitted on the inner ends of the two first connectors. A second spring is connected between the sealing ring and the bottom wall of the docking box, and a lever is provided on the side wall of the sealing ring that slides out of the corresponding side opening.

[0014] As can be seen from the above technical solution, the present invention provides a treatment device for empyema:

[0015] 1. When treating patients with empyema, only one puncture point needs to be created for the main tube to be inserted. During subsequent treatment, the main tube can be switched with different treatment devices by rotating the docking box and the box cover. This allows the main tube to be used for multiple treatment methods, making switching convenient and facilitating the identification of the various equipment tubes. The internal passage of the main tube is divided into two by the partition strip, enabling the main tube to simultaneously perform the functions of delivery and aspiration.

[0016] 2. Water is injected into one of the main pipes through the water injection device, and the negative pressure suction device is used to draw water from the other pipe of the main pipe to flush and clean the pus adhering to the inner wall of the main pipe and other pipes, so as to ensure that the pus extracted in the subsequent sampling is in real time.

[0017] 3. The control mechanism utilizes the relative rotation of the docking box and the box cover to move the drive roller to the top of the arc protrusion, thereby lifting the traction rope by squeezing the control block. This achieves the sealing of the insertion end port while the first joint is docked with the self-cleaning joint, improving the efficiency of the pipeline cleaning operation.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] like Figure 1-5 As shown, this embodiment provides a treatment device for empyema, including a docking box 1 and a main tube 2.

[0032] Please see Figure 1 and Figure 2The top of the docking box 1 is axially rotatable and equipped with a cover 11. The bottom edge of the cover 11 is provided with an annular groove. The top of the side wall of the docking box 1 is annular and rotatably embedded in the annular groove. A pair of first connectors 12 are symmetrically arranged at the bottom of the docking box 1 with the pivot of the cover 11 as the center. Multiple pairs of second connectors 13 are arranged on the cover 11. The docking box 1 and the cover 11 can be rotated relative to each other so that the inner ends of two first connectors 12 can be connected to any pair of second connectors 13. Each second connector 13 is provided with a connecting pipe 131 at its outer end. Each connecting pipe 131 is connected to the corresponding device.

[0033] like Figure 2 and Figure 4 As shown, the docking box 1 has side openings 14 on both sides. A sealing ring 15 is slidably fitted onto the inner ends of the two first connectors 12. The inner ring of the sealing ring 15 has a sealing ring. A second spring 151 connects the sealing ring 15 to the bottom wall of the docking box 1. When the first connector 12 and the second connector 13 are docked, the second spring 151 provides an elastic force to push the sealing ring 15 towards the second connector 13, so that the sealing ring 15 can surround the outer side of the connection between the first connector 12 and the second connector 13, improving the sealing effect and preventing leakage. In addition to preventing leakage, the sealing ring 15 also serves as a limiting device, preventing the docking box 1 and the cover 11 from rotating after the first connector 12 and the corresponding second connector 13 are connected. This also prevents the first connector 12 and the corresponding second connector 13 from shifting or misaligning. The side wall of the sealing ring 15 is provided with a lever 152 that slides out of the corresponding side opening 14. When switching the connection between the first connector 12 and the second connector 13, pressing the lever 152 will disengage the sealing ring 15 from the second connector 13, allowing the docking box 1 and the cover 11 to continue rotating.

[0034] A partition strip 21 is provided in the middle of the main body 2, which divides the interior of the main body 2 into two parts of the pipeline. One end of the main body 2 is connected to two branch pipes 22 respectively, and the two branch pipes 22 are respectively connected to the outer end of the first connector 12. The other end of the main body 2 is the insertion end 23, which is used to penetrate the patient's chest cavity. A monitoring pipeline 24 is provided on the outside of the main body 2. One end of the monitoring pipeline 24 is located at the insertion end 23 and is equipped with a monitoring probe 241, and the other end is connected to a pH monitor.

[0035] In practical use, the insertion end 23 of the main tube 2 is inserted into the patient's chest cavity. The monitoring probe 241 of the monitoring tube 24 enters the chest cavity along with the main tube 2 to monitor the internal pH value. Each pair of second connectors 13 is connected to the corresponding device through the connecting tube 131 to correspond to different treatment methods. According to the treatment needs, the docking box 1 and the box cover 11 are rotated relative to each other, so that the two first connectors 12 switch between each pair of second connectors 13 to match and connect the corresponding treatment device.

[0036] When treating patients with empyema, this invention only requires creating one puncture point for the main tube 2 to be inserted. During subsequent treatments, the docking box 1 and the box cover 11 are rotated relative to each other to switch the docking of the main tube 2 with different treatment devices, so that the main tube 2 can be used for multiple treatment methods. The switching is convenient and it is easy to distinguish and identify the pipes of each device. Furthermore, the partition strip 21 divides the internal passage of the main tube 2 into two, so that the main tube 2 can simultaneously perform the functions of delivery and aspiration.

[0037] During treatment, multiple sampling tests are required to determine the type and proportion of pathogenic bacteria. If anaerobic bacteria are predominant, oxygen therapy is necessary; if aerobic bacteria are predominant, oxygen desiccation is required to eliminate the corresponding pathogens. However, during drainage, pus already adheres to the inner walls of the main tubes (such as tube 2). The state of pathogenic bacteria in the pus within these tubes is not the same as the real-time state of pathogenic bacteria in the pus within the pleural cavity. Subsequent pleural cavity pus samples will carry away this adhered pus, causing the pus within the tubes to mix with the retrieved pleural cavity pus samples. This mixing can easily lead to inaccurate test results, making it impossible to develop a targeted and effective treatment plan.

[0038] Therefore, preferably, the second connector 13 is provided with at least three pairs to ensure the basic treatment needs. One pair of the second connectors 13 is a self-cleaning connector. The two self-cleaning connectors are respectively connected to a water injection device and a negative pressure suction device through the connecting pipe 131. The water injection device injects water into one of the pipes of the main body 2, and the negative pressure suction device draws water from the other pipe of the main body 2 to flush and clean the pus adhering to the inner wall of the main body 2 and other pipes, so as to ensure that the pus extracted in the subsequent sampling is in real time.

[0039] In addition, the second pair of second connectors 13 are respectively connected to oxygen supply equipment and negative pressure suction equipment through connecting pipe 131 to perform oxygen supply or oxygen extraction treatment, drainage and pus treatment, and sampling operation. The second pair of second connectors 13 are assigned to the above-mentioned operations mainly to reduce the number of external pipelines and facilitate management. Of course, according to actual needs, multiple pairs of second connectors 13 can also be used to correspond to each operation.

[0040] The third pair of second connectors 13 are connected to external irrigation equipment through connecting pipe 131 for sodium bicarbonate irrigation. A certain amount of sodium bicarbonate is prepared according to the pH value measured by the pH monitor. The irrigation equipment is used to irrigate the patient's pleural cavity with sodium bicarbonate. Since pathogens usually prefer an acidic environment, maintaining the pH value in the pleural cavity above 7 is beneficial to eliminate pathogens to a certain extent.

[0041] It should be noted that the pH monitor, water injection equipment, negative pressure suction equipment, oxygen delivery equipment, and irrigation equipment mentioned above are all existing technology products and do not require further elaboration.

[0042] like Figure 3 and Figure 5 As shown, further, a notch 25 is provided between the baffle strip 21 and the end of the insertion end 23 of the main tube 2. Hinges 26 are rotatably connected to both sides of the port of the insertion end 23. The hinges 26 are connected to the end of the insertion end 23 via elastic members 261 to provide elastic force that allows the two hinges 26 to separate and extend outwards. The elastic members 261 can be made of elastic silicone. The two hinges 26 can be rotated inwards to seal the port of the insertion end 23. A control mechanism 3 is provided inside the docking box 1 to drive the two hinges 26 to rotate inwards. When cleaning the tubing before sampling, the control mechanism 3 drives the two hinges 26 to rotate inwards to seal the port of the insertion end 23, allowing some of the liquid in the main tube 2 to be drawn out through the notch 25 from the other part of the tubing, preventing the cleaning liquid from draining into the pleural cavity, thus preventing the cleaned pus from returning to the patient's pleural cavity. Simultaneously, it increases the water pressure inside the main tube 2, improving the cleaning effect.

[0043] Preferably, the edge of the hinge 26 is provided with a limiting block 262 to prevent the hinge 26 from rotating excessively into the port of the insertion end 23, which would cause a sealing gap. The inner side of the hinge 26 is provided with a sealing plug 263 to improve the sealing effect.

[0044] like Figures 2-5As shown, specifically, the partition bar 21 has a traction channel 211 opened along its length inside. The control mechanism 3 includes a ring seat 31, a control sleeve 32, and a traction rope 33. The ring seat 31 is installed at the bottom of the inner cavity of the docking box 1. The ring seat 31 is annular and its center is located on the rotation axis of the box cover 11. The top of the ring seat 31 is provided with arc-shaped protrusions 311 on both sides corresponding to the two self-cleaning connectors. The arc-shaped protrusions 311 are smoothly connected to the top of the ring seat 31. The control sleeve 32 is located at the bottom of the box cover 11, and a control block 321 is slidably inserted into its bottom. Rollers 323 are connected to both sides of the control block 321 through support rods 322. The rollers 323 are located above the ring seat 31. A first spring 34 is connected between the control block 321 and the control sleeve 32 to provide elastic force. Pushing the control block 321 causes the roller 323 to abut against the top of the ring seat 31. When the docking box 1 and the box cover 11 are rotated relative to each other so that the first connector 12 is connected to the self-cleaning connector, the roller 323 will move to the top of the arc protrusion 311, so that the control block 321 is pressed into the control sleeve 32. The traction rope 33 is located in the traction channel 211. One end of the rope slides through the bottom of the docking box 1 and is connected to the control block 321. The other end is located at the notch 25 and is forked with two branch ropes 331. The two branch ropes 331 are respectively connected to the inner side of the two hinges 26. When the control block 321 is pressed into the control sleeve 32, the traction rope 33 will be lifted by the control block 321, and then the two hinges 26 will be rotated inward and gathered through the branch ropes 331, thereby sealing the port of the insertion end 23. The control mechanism 3 utilizes the relative rotation between the docking box 1 and the box cover 11 to drive the roller 323 to move to the top of the arc protrusion 311, thereby pulling the traction rope 33 by squeezing the control block 321. This achieves the simultaneous sealing of the insertion end 23 port when the first connector 12 is docked with the self-cleaning connector, thus improving the efficiency of the pipeline cleaning operation.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
