Description

Technical Field

[0001] This invention relates to the field of drainage nursing technology, and in particular to a drainage device for use in ICU nursing care. Background Technology

[0002] Drainage devices used in ICU (Intensive Care Unit) nursing are medical devices used to drain excess fluid and gas from a patient's body cavities. These include various drainage tubes, drainage bags, and water-seal bottles. Their main functions are to maintain intracavitary pressure balance, prevent the spread of infection, promote the absorption of inflammation, and aid patient recovery. During nursing care, it is essential to keep the device sealed, unobstructed, and properly secured, and to observe and accurately record the drainage fluid.

[0003] A drainage and nursing device, as disclosed in CN116474182A, includes: a support assembly for supporting the drainage and nursing device; a lifting assembly located at the upper end of the support assembly; a fluid guiding assembly located at the upper end of the lifting assembly; and an inlet pipe located at one end of the fluid guiding assembly. The lifting assembly includes a buoyancy rod with a buoyancy ball at its lower end, a rotating shaft at the top of one end of the buoyancy rod, a second gear movably connected to the outside of the rotating shaft, an arc-shaped groove at the end of the second gear away from the buoyancy rod, and an L-shaped support rod at the top of one end of the buoyancy rod and at the bottom of the second gear. The component includes a protective cover, an internally rotatably connected drainage groove, a rocker arm rotatably connected to one end of the protective cover, a first rotating shaft located in the middle of the rocker arm, a telescopic sleeve located on one side of the rocker arm, the telescopic sleeve rotatably connected to the drainage groove via a second rotating shaft, a connecting rod rotatably connected to the side of the rocker arm away from the telescopic sleeve, and an elastic element rotatably connected to the bottom of the rocker arm.

[0050] Each collection bottle 32 is provided with a docking port at the top, which is used to dock the drainage tube 34.

[0051] Specifically, the connecting bottle opening includes a connecting pipe 2, which is located at the top of the collection bottle 32 and is fixedly connected to it. The connecting pipe 2 is a vertical tube, and a first magnetic ring is coaxially fixed inside the top tube. A rubber sealing ring 35 is fixedly sleeved on the drainage tube 34, and a second magnetic ring is coaxially fixed inside the rubber sealing ring 35. The first and second magnetic rings are magnetically attracted to each other, and the rubber sealing ring 35 is used to seal the connecting pipe 2.

[0052] Two vertically placed support plates 18 are fixed to the top of the mobile box 1, one in front of the other and parallel to each other. The notch at the top of the mobile box 1 is located between the two support plates 18. A bending mechanism for bending the drainage tube 34 is installed between the two support plates 18, and the bending mechanism is driven by the first loading frame 6 through a transmission assembly.

[0053] Specifically, the bending mechanism includes two hinged bending plates 25, which are connected by a tie rod 27. Two horizontally positioned slide rods 23, each extending horizontally in the front-to-back direction, are placed between the two support plates 18. The two slide rods 23 are positioned one above the other and are slidably connected to both support plates 18. The tie rod 27 is located between the two slide rods 23 and is parallel to them.

[0054] Two bending plates 25 correspond one-to-one with two sliding rods 23, and the end of each bending plate 25 away from the pull rod 27 is rotatably connected to the corresponding sliding rod 23.

[0061] The transmission components include a rack 11 and a gear 10. The rack 11 is fixed vertically to the left side frame of the first loading frame 6. Specifically, several connecting rods 12 are fixedly arranged between the rack 11 and the left side frame of the first loading frame 6. The gear 10 is coaxially and fixedly connected to the winding reel 9. The rack 11 and the gear 10 mesh with each other.

[0063] Specifically, the reset assembly includes a first spring 24. Two limiting grooves 21 are formed on each of the two support plates 18 in the vertical direction. The two limiting grooves 21 on the same support plate 18 are arranged one above the other. The openings of the two upper limiting grooves 21 are horizontally opposite each other, and the openings of the two lower limiting grooves 21 are horizontally opposite each other.

[0064] Each limiting slide groove 21 has a limiting slider 22 installed in a limiting sliding position.

[0066] Two first springs 24 on the same support plate 18 are located between two limit sliders 22.

[0067] The drainage tube 34 can be detachably installed onto the two bending plates 25 via a fastener.

[0068] Specifically, the fastening element includes a first strap 26 and a second strap 28 for securing the drainage tube 34 to the two bent plates 25. Each of the two bent plates 25 has a first strap 26, with both movable ends of each first strap 26 passing through the corresponding bent plate 25. A second strap 28 is provided on the pull rod 27, with both movable ends of the second strap 28 passing through the pull rod 27. The hinge point of the two bent plates 25 is located between the two movable ends of the second strap 28.

[0069] The drainage tube 34 has a built-in control valve.

[0070] Working principle: When using this drainage device for ICU critical care, push the mobile box 1 to the patient's bedside. Then, insert the drainage tube 34 into the connecting tube 2 at the top of the collection bottle 32 in the first loading frame 6. At the same time, make the rubber sealing ring 35 coaxially contact the connecting tube 2. Under the magnetic attraction of the first magnetic ring and the second magnetic ring, the rubber sealing ring 35 abuts against the opening of the connecting tube 2, thereby sealing the connecting tube 2.

[0071] Next, the drainage tube 34 is aligned vertically with the right end faces of the two bent plates 25, and secured to the two bent plates 25 using two first binding straps 26 and one second binding strap 28. The securing process involves making the first binding strap 26 perpendicular to the drainage tube 34, with its two movable ends passing through the bent plates 25 and engaging until the drainage tube 34 is tightly bound. Two through holes are provided on the bent plates 25, each corresponding to one of the two movable ends of the first binding strap 26. The drainage tube 34 is positioned between the two through holes, with both movable ends of the first binding strap 26 passing through their respective through holes. The process of the second binding strap 28 tightening the drainage tube 34 is the same as with the first binding strap 26, except that the through hole is located on the pull rod 27. Further details will not be elaborated upon here.

[0072] Next, the other end of the drainage tube 34 is inserted into the human body. Then, the control valve on the drainage tube 34 is opened, and the tissue fluid in the human body flows into the corresponding collection bottle 32 through the drainage tube 34.

[0073] At this point, as the amount of tissue fluid in collection bottle 32 increases, the reading on pressure sensor 7 also increases. Simultaneously, the level of tissue fluid in collection bottle 32 gradually rises. Medical personnel can determine and record the outflow of tissue fluid using the scale 33 and the reading on pressure sensor 7 to facilitate monitoring of the patient's condition.

[0074] When the tissue fluid in the collection bottle 32 has been collected to a certain amount, medical staff can close the control valve on the drainage tube 34. Then, the electric push rod 5 is activated, and the telescopic axis of the electric push rod 5 retracts downward, driving the first loading frame 6 to move down through the notch into the moving box 1.

[0075] As the first loading frame 6 moves downward, it drives the rack 11 to move downward simultaneously. At the same time, due to gravity, the rubber sealing ring 35 disengages from the connecting pipe 2.

[0076] As rack 11 moves downward, it gradually comes into contact with gear 10 and, upon contact, pushes gear 10 to rotate. Gear 10 drives winding wheel 9 to rotate, and winding wheel 9 rotates clockwise to wind up pull rope 13. Pull rope 13 pulls rotating frame 29 to the left, and rotating frame 29 drives pull rod 27 to the left. Pull rod 27 pulls two bending plates 25 from a vertical "I" position to a V position. During this process, the two bending plates 25 bend drainage tube 34, thereby preventing residual tissue fluid in drainage tube 34 from flowing out.

[0077] It should be noted that the opening of the drainage tube 34 was not removed from the connecting tube 2 before it was bent to a completely closed position. This process can be achieved by using a matching connecting tube 2, taking advantage of the characteristics of the bending process of the drainage tube 34 itself.

[0078] When the two bending plates 25 bend the drainage tube 34, the ends away from the pull rod 27 move closer to each other. At this time, the two sliding rods 23 slide closer and drive the corresponding limiting slider 22 to compress the connected first spring 24.

[0079] When the telescopic shaft of the electric push rod 5 retracts downward, it drives the follower plate to move downward. The follower plate drives the transmission shaft 39 to move downward synchronously, and the transmission shaft 39 pushes the two swing arms 37 to rotate downward. The two swing arms 37 pull the second loading frame 16 to slide to the left through the corresponding fixed shaft 17 and the extension plate 15. During this process, the second loading frame 16 drives the connecting block 36 to stretch the second spring 40. Before the first loading frame 6 and the collection bottle 32 inside the first loading frame 6 are completely slid into the moving box 1, the second loading frame 16 is never crossed with the notch.

[0080] When rack 11 moves down to disengage from gear 10, second loading frame 16 slides directly above the notch. Prior to this, first loading frame 6 and the collection bottle 32 within it have already slid completely into moving box 1. At this point, under the elastic force of first spring 24, pull rope 13 is released from winding reel 9, and two bending plates 25 change from a V-shape to an I-shape. Drainage tube 34 changes from a bent state to a vertical state and is finally inserted into the connecting pipe 2 at the top of collection bottle 32 within second loading frame 16. After drainage tube 34 is inserted into connecting pipe 2, rubber sealing ring 35 covers connecting pipe 2, and the first magnetic ring and second magnetic ring attract each other.

[0081] Afterwards, medical staff open the control valve on the drainage tube 34 to continue draining tissue fluid. During this process, medical staff can open the box door 3, take out the old collection bottle 32 from the first loading frame 6, and put in the new collection bottle 32.

[0082] When the collection bottle 32 in the second loading frame 16 has collected enough tissue fluid, the medical staff closes the control valve on the drainage tube 34. At this time, the electric push rod 5 is activated again, and its telescopic shaft extends upward. During this process, the drive shaft 39 pushes the two swing arms 37 to rotate upward. Simultaneously, under the elastic force of the second spring 40 and the pushing force of the two swing arms 37, the second loading frame 16 drives the collection bottle 32 to slide back to the right.

[0083] Simultaneously, the telescopic shaft of the electric push rod 5 pushes the first loading frame 6 upward and eventually passes through the notch. During this process, the rack 11 contacts the gear 10 and pushes the gear 10 to rotate in the opposite direction. The gear 10 drives the winding reel 9 to wind the pull rope 13 in the opposite direction, and the two bending plates 25 rotate again from the "I" position to the V position. The drainage tube 34 is bent again, and at the same time, as the second loading frame 16 slides back, it is removed from the connecting pipe 2 of the collection bottle 32 inside the second loading frame 16.

[0084] When rack 11 moves upward and disengages from gear 10, the first loading frame 6 completely protrudes from the notch. At this time, the two bending plates 25 return from the V-shape to the I-shape, and the drainage tube 34 is reinserted into the connecting pipe 2 of the collection bottle 32 inside the first loading frame 6. Afterward, medical personnel can reopen the control valve on the drainage tube 34 to continue draining the tissue fluid.

[0085] To reduce the workload of medical staff, a microcomputer system can be installed inside the mobile box 1, and the control valve can be replaced with a solenoid valve. This allows the solenoid valve, electric actuator 5, and pressure sensor 7 to be electrically connected to the microcomputer system, thereby enabling automatic control through the microcomputer system.

[0086] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
