Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to an automatic T-tube connection and anti-slip device for drainage bags. Background Technology

[0002] T-tubes are widely used in clinical practice, mainly during biliary tract surgery. After biliary tract surgery, a T-tube needs to be placed for drainage, such as after choledochotomy for common bile duct stones, choledochoenterostomy, or biliary tumor resection. After the T-tube is placed, a sterile drainage bag needs to be connected to observe the drainage fluid. This includes observing the amount and characteristics of the drainage fluid, such as how many milliliters of bile are discharged each day, whether there is bleeding in the drainage fluid, and whether there is distended bile, etc.

[0003] However, in the current technology, medical staff need to manually connect the T-tube and the drainage tube. Specifically, the T-tube and the drainage tube are inserted together, then the connection is wrapped with gauze, and finally the gauze is fixed with medical tape. This operation is very troublesome, and because the operating procedures of different medical staff cannot be effectively guaranteed, it will also lead to the problem of unreliable fixation. If the connection is dislodged when the patient gets up or moves, the drainage fluid will leak out, causing pollution to the patient's surrounding environment and increasing the corresponding cleaning work.

[0004] Furthermore, if the drainage bag is positioned above the abdominal T-tube wound while the patient is moving around, the fluid in the drainage bag may flow back, which could lead to an infection risk for the patient.

[0005] Therefore, an automatic T-tube connection and anti-slip device for drainage bags was proposed to solve the above problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an automatic T-tube connection to the drainage bag anti-slip device that allows for rapid connection of the T-tube to the drainage bag, prevents backflow of the collected liquid in the drainage bag, and provides an alarm when the collected liquid backflows, thereby solving the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an automatic T-tube connection and anti-slip device for drainage bags, comprising an outer shell column, a T-tube, a drainage bag tube, and a drainage bag, wherein a T-tube is inserted into an insertion port at the upper end of the outer shell column, and a drainage bag tube is inserted into an insertion port at the lower end of the outer shell column, and a drainage bag is fixedly connected to the bottom end of the drainage bag tube; an automatic connection component is provided inside the outer shell column, and the automatic connection component includes an anti-backflow infection component;

[0010] The automatic connection component includes a cube block 401, which is fixedly connected to the inner cavity of the outer shell column 1. The inner cavity of the cube block is symmetrically provided with inner arc plates, and convex balls are fixedly connected to the inner arc plates at equal intervals. Outer arc plates are provided on the outer side of the inner arc plates, and concave holes are opened at equal intervals on the inner surface of the outer arc plates.

[0011] The anti-backflow infection component includes an auxiliary cavity, in which a U-shaped block is slidably connected in the vertical channel of the auxiliary cavity, and in which a magnetic sealing block is slidably connected in the horizontal channel of the auxiliary cavity.

[0012] As an improvement, the cube block is provided with a first flow port and a second flow port. A drive motor is symmetrically fixedly connected to the inner cavity surface of the cube block. The bottom end of each drive motor is fixedly connected to a gear through a shaft. A first auxiliary rod is fixedly connected to one side of each drive motor. A first rack is slidably connected to the bottom end of each first auxiliary rod. The first rack is fixedly connected to the inner arc plate.

[0013] As an improvement, a second auxiliary rod is fixedly connected to the other side of each drive motor, and a second rack is slidably connected to the bottom end of each of the second auxiliary rods. The second rack is fixedly connected to the outer arc plate.

[0014] As an improvement, a cylindrical cavity is fixedly connected to the upper end face of the cube block, and telescopic rods are symmetrically fixedly connected to the inner wall of the cylindrical cavity. A third convex arc block is fixedly connected to the outer end of each telescopic rod.

[0015] As an improvement, the bottom of the auxiliary cavity is symmetrically provided with push switches, all of which are located on the bottom surface of the herringbone block. A rope is fixedly connected to the middle of the upper surface of each herringbone block. A guide auxiliary hole rod is fixedly connected to the inner wall of the auxiliary cavity. The rope slides through the guide auxiliary hole rod. A spring is fixedly connected to each magnetic sealing block. The end of the spring away from the magnetic sealing block is fixedly connected to the upper inner wall of the auxiliary cavity.

[0016] As an improvement, a buzzer and an electronic switch are fixedly connected to the upper end of the outer shell column.

[0017] As an improvement, the convex ball is adapted to the concave cavity.

[0018] As an improvement, the auxiliary cavity is divided into a transverse cavity and a vertical cavity.

[0019] As an improvement, water is placed in the auxiliary cavity between the spiral block and the magnet sealing block.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides an automatic T-tube connection to a drainage bag anti-slip device, which has the following beneficial effects:

[0022] 1. By setting up an automatic connection component, it differs from the existing technology where medical staff insert the T-tube and drainage bag tube together, then wrap the connection with gauze, and finally use medical tape to fix the gauze. This avoids the problem of insecure fixation due to different medical staff's operating procedures. When the patient gets up or moves, the connection may detach, causing drainage fluid to leak out, polluting the patient's surrounding environment, and increasing the subsequent cleaning work.

[0023] 2. By setting the convex ball on the inner arc plate, the concave hole on the outer arc plate, and the convex point on the third convex point arc block, the stability of fixing the T tube and the drainage bag tube can be effectively guaranteed, and the T tube and the drainage bag tube fixed under the action of external force can be effectively prevented from loosening.

[0024] 3. When the switch is pressed, the water in the auxiliary cavity moves, indirectly causing the water to move against the two magnetic sealing blocks in the transverse channel of the auxiliary cavity. The opposing magnetic sealing blocks will gradually block the first and second diversion ports. At this time, the fluid in the drainage bag cannot flow back into the T tube through the drainage bag tube. That is, by setting up the anti-backflow infection component, the backflow of fluid in the drainage bag can be avoided when the patient is walking and moving around, because the drainage bag is higher than the wound position of the abdominal T tube. This reduces the patient's risk of infection.

[0025] 4. By setting the push switch and buzzer, after the loop block moves away from the push switch, the push switch is no longer pressed. At this time, the buzzer, which is electrically connected to the push switch, will emit a buzzing sound to provide an alarm reminder. Attached Figure Description

[0042] Example

[0043] Please refer to Figures 1 to 10 As shown:

[0044] To address the problems mentioned in the technical solutions, this application provides an automatic T-tube connection and anti-slip device for drainage bags, comprising an outer shell column 1, a T-tube 2, a drainage bag tube 3, and a drainage bag 301. The T-tube 2 is inserted into the upper end of the outer shell column 1, and the drainage bag tube 3 is inserted into the lower end of the outer shell column 1. The bottom end of the drainage bag tube 3 is connected to and fixed with the drainage bag 301. An automatic connection component is provided inside the outer shell column 1, and the automatic connection component includes an anti-backflow infection component.

[0045] The automatic connection assembly includes a cube block 401, which is fixedly connected to the inner cavity of the outer shell column 1. Inner arc plates 408 are symmetrically arranged within the inner cavity of the cube block 401. Convex balls 409 are fixedly connected to each inner arc plate 408 at equal intervals. Outer arc plates 412 are arranged on the outer side of the inner arc plates 408. Inner recesses 413 are equidistantly formed on the inner surface of the outer arc plates 412. A first flow inlet 402 and a second flow inlet 403 are formed on the cube block 401. Drive motors 404 are symmetrically fixedly connected to the inner surface of the cube block 401. Gears 405 are fixedly connected to the bottom of each drive motor 404 via shafts. A first auxiliary rod 406 is fixedly connected to one side of the drive motor 404. A first rack 407 is slidably connected to the bottom end of the first auxiliary rod 406. The first rack 407 is fixedly connected to the inner arc plate 408. A second auxiliary rod 410 is fixedly connected to the other side of the drive motor 404. A second rack 411 is slidably connected to the bottom end of the second auxiliary rod 410. The second rack 411 is fixedly connected to the outer arc plate 412. A cylindrical cavity 414 is fixedly connected to the upper end face of the cube block 401. Telescopic rods 415 are symmetrically fixedly connected to the inner wall of the cylindrical cavity 414. A third protruding arc block 416 is fixedly connected to the outer end of each telescopic rod 415.

[0046] The anti-backflow infection component includes an auxiliary cavity 501, a herringbone block 503 slidably connected in the vertical channel of the auxiliary cavity 501, a magnetic sealing block 505 slidably connected in the horizontal channel of the auxiliary cavity 501, a push switch 502 symmetrically arranged at the bottom of the inner cavity of the auxiliary cavity 501, the push switches 502 are all located on the bottom surface of the herringbone block 503, a rope 504 is fixedly connected to the middle of the upper surface of the herringbone block 503, a guide auxiliary hole rod 506 is fixedly connected to the inner wall of the auxiliary cavity 501, the rope 504 slides through the guide auxiliary hole rod 506, a spring 507 is fixedly connected to the magnetic sealing block 505, the end of the spring 507 away from the magnetic sealing block 505 is fixedly connected to the upper inner wall of the auxiliary cavity 501, and a buzzer 508 and an electric control switch 509 are fixedly connected to the upper end of the outer shell column 1.

[0047] in:

[0048] The automatic connection component can connect the T tube 2 and the drainage bag tube 3 together, so that the fluid drained from the T tube 2 can be transferred to the drainage bag 301 through the drainage bag tube 3. Medical staff do not need to manually connect the T tube 2 and the drainage bag tube 3. At the same time, the component can effectively ensure the stability of the connection and prevent the connection between the T tube 2 and the drainage bag tube 3 from loosening due to external force.

[0049] The anti-backflow infection component mainly prevents the backflow of fluid in the drainage bag tube 3 when the drainage bag tube 3 is higher than the wound position of the abdominal T tube 2, thereby reducing the risk of infection and ensuring the normal operation of the drainage work. Except for the buzzer 508 and the electric control switch 509, the other components in the anti-backflow infection component are all in a set and are arranged symmetrically.

[0050] The outer shell column 1 has through insertion interfaces at both the upper and lower ends. The upper insertion interface is mainly used for the insertion of T tube 2, and the lower insertion interface is mainly used for the insertion of drainage bag tube 3.

[0051] The first transfer port 402 connects the auxiliary cavity 501 on the cube block 401 with the cylindrical cavity 414; the drive motor 404 and the electric control switch 509 are electrically connected and controlled by an external system; the gear 405 is adapted to the first rack 407 and the second rack 411.

[0052] The convex sphere 409 is compatible with the concave cavity 413;

[0053] The telescopic rod 415 is electrically connected to the electric control switch 509 and is controlled by an external system.

[0054] The auxiliary cavity 501 is divided into a transverse cavity and a vertical cavity;

[0055] There is an electrical connection between the press switch 502 and the buzzer 508. When the press switch 502 is not pressed, the buzzer 508 will emit a buzzing sound to remind the patient to pay attention to the location of the drainage bag tube 3 and the abdominal T tube 2 at the wound site.

[0056] Water is placed in the auxiliary cavity 501 between the loop block 503 and the magnetic sealing block 505;

[0057] The guide auxiliary hole rod 506 is mainly used for the movement of the rope 504 to prevent the rope 504 from rubbing directly in the auxiliary cavity 501 during movement;

[0058] Spring 507 is mainly used for resetting the magnetic blocking block 505.

[0059] The electric control switch 509 controls the on / off state of the overall device circuit through an external control system.

[0060] The working principle of all the content in the above embodiments is as follows:

[0061] In the initial state: T-tube 2 and drainage bag tube 3 are not inserted into the first diversion port 402 and the second diversion port 403, the push switch 502 is pressed by the loop block 503, the third convex arc block 416 is not in contact with T-tube 2, the drainage bag tube 3 is not clamped by the inner arc plate 408 and the outer arc plate 412, the magnetic sealing block 505 does not block the first diversion port 402 and the second diversion port 403, and the spring 507 is not stretched.

[0062] Sub-process:

[0063] The following is the working process of the automatic connection component:

[0064] Summary: After inserting the T-tube 2 and drainage bag tube 3 into the upper and lower insertion interfaces of the outer shell column 1, the electric control switch 509 is turned on, and the T-tube 2 and drainage bag tube 3 will be quickly fixed. The fluid flowing through the T-tube 2 will enter the drainage bag tube 3 through the first diversion port 402 and the second diversion port 403 with the assistance of the inner wall of the cube block 401, thereby collecting the fluid in the patient's abdomen into the drainage bag 301 connected to the drainage bag tube 3;

[0065] In practical use, the T-tube 2 is inserted into the upper end connector of the outer shell column 1, and the drainage bag tube 3 is inserted into the lower end connector of the outer shell column 1. During insertion, the T-tube 2 will be inserted into the column cavity 414. At this time, the third protruding arc block 416 will be located in the inner cavity of the T-tube 2, and the drainage bag tube 3 will be sandwiched between the inner arc plate 408 and the outer arc plate 412. At this time, the electric control switch 509 is turned on. The electric control switch 509 will start the drive motor 404 and the telescopic rod 415 through the external control system. The started drive motor 404 will rotate with the fixedly connected gear 405. (See reference...) Figure 6 The rotating gear 405 causes the first rack 407 and the second rack 411 to move towards each other with the assistance of the first auxiliary rod 406 and the second auxiliary rod 410. When the first rack 407 and the second rack 411 move towards each other, the outer arc plate 412 gradually approaches the inner arc plate 408, clamping the drainage tube 3 between them. During this clamping, the convex ball 409 moves into the inner concave cavity 413. At this time, the elastic drainage tube 3, with the assistance of the convex ball 409 and the inner concave cavity 413, is firmly positioned between the inner arc plate 408 and the outer arc plate 412, thus fixing the drainage tube 3. Furthermore, when the inner arc plate 408 and the outer arc plate 412 clamp the drainage tube 3, the telescopic rod 415 also retracts. (See reference...) Figure 7 , Figure 8When the telescopic rod 415 retracts, it will bring the third convex arc block 416 closer to the inner wall of the T tube 2. Finally, the T tube 2 will be fixed by the pull of a set of third convex arc blocks 416. That is, through the setting of the automatic connection component, it is different from the existing technology where medical staff insert the T tube 2 and the drainage bag tube 3 together, then wrap the connection with gauze, and finally use medical tape to fix the gauze. This avoids the problem of unreliable fixation due to the inability to effectively guarantee the operation standards of different medical staff. When the patient gets up or moves, the connection part may detach, causing drainage fluid to leak out, polluting the patient's surrounding environment, and increasing the corresponding cleaning work and other subsequent problems.

[0066] Furthermore, by setting the convex ball 409 on the inner arc plate 408 and the concave hole 413 on the outer arc plate 412, as well as setting the convex point on the third convex point arc block 416, the stability of fixing the T tube 2 and the drainage bag tube 3 can be effectively guaranteed, and the T tube 2 and the drainage bag tube 3 fixed under the action of external force can be effectively prevented from loosening.

[0067] Please refer to the above work process. Figures 3 to 8 .

[0068] The following is the working process of the anti-backflow infection component:

[0069] Furthermore, initially, when the outer shell column 1 is in a normal vertical position, the press switch 502 is pressed by the herringbone block 503. Further, if the drainage bag 301 is higher than the wound location of the abdominal T-tube 2 when the patient is moving, the outer shell column 1 will tilt and invert to a certain extent. At this time, the herringbone block 503 in the auxiliary cavity 501 will move away from the press switch 502. The press switch 502 will then push the water in the auxiliary cavity 501 to move, thereby causing the two magnetic... When the magnetic sealing block 505 moves, the spring 507 will be stretched. The magnetic sealing blocks 505 moving in opposite directions will gradually block the first diversion port 402 and the second diversion port 403. At this time, the fluid in the drainage bag 301 cannot flow back into the T tube 2 through the drainage bag tube 3. That is, by setting up the anti-backflow infection component, the backflow of fluid in the drainage bag 301 can be avoided when the patient is walking and moving around, because the drainage bag 301 is higher than the wound position of the abdominal T tube 2. This reduces the patient's risk of infection.

[0070] Furthermore, after the loop block 503 moves away from the press switch 502, the press switch 502 is no longer pressed. At this time, the buzzer 508, which is electrically connected to the press switch 502, will emit a buzzing sound to provide an alarm reminder. Further, when the patient realizes this and adjusts the outer shell column 1 back to its normal vertical position, the loop block 503 will pull the magnetic blocking block 505 back to its initial state through the rope 504. That is, the magnetic blocking block 505 will no longer block the cube block 401 and the first diversion port 402. The loop block 503 will resume pressing the press switch 502. At this time, the buzzer 508 will stop buzzing and alarming. The fluid flowing out of the T tube 2 can then pass through the cube block 401 and the first diversion port 402 and flow into the drainage bag 301 through the drainage bag tube 3, thus completing the collection of the fluid.

[0071] Please refer to the above work process. Figures 1 to 4 , Figure 9 , Figure 10 .

[0072] Overview:

[0073] By using an automatic connection component, the cumbersome connection steps of existing technologies are avoided. This also prevents problems such as insecure fixation due to inconsistent operating procedures among different medical staff, which could lead to the connection detaching when the patient gets up or moves, causing drainage fluid leakage, contaminating the patient's surrounding environment, and increasing subsequent cleaning work. At the same time, the anti-backflow infection component prevents backflow of fluid from the drainage bag 301 when it is higher than the wound position of the abdominal T tube 2 when the patient is moving around, thereby reducing the patient's risk of infection.
