Description

Technical Field

[0001] This invention relates to the field of medical and nursing device technology, specifically to a drainage device for thoracic surgery to prevent dislodgement. Background Technology

[0002] After thoracic surgery, residual fluid, blood, or gas often remains in the pleural cavity. To prevent this accumulation from affecting wound healing and respiratory function, closed thoracic drainage is commonly used clinically. The drainage device typically includes a drainage bottle, connecting tubing, and an interface for connecting to the patient's chest drainage tube. During nursing care, the drainage bottle must be placed below the patient's chest cavity and reliably connected to the patient via tubing. However, existing drainage devices have some shortcomings in use: 1. Unstable drainage bottle fixation: Drainage bottles are often simply placed on the floor or hung beside the bed, making them prone to tipping over or slipping when the patient moves, the bed is adjusted, or they are accidentally touched, leading to drainage fluid leakage, environmental contamination, and even the risk of retrograde infection from the drainage tube. 2. Easy loosening of tubing connections: The tubing connecting the patient's chest drainage tube to the drainage bottle, especially the connection near the patient's body, is often secured with a simple plug or tape. When patients turn over, get up, or get out of bed, the tubing can easily be pulled, causing the connections to loosen, leak air, or break completely. This not only affects the drainage effect but can also lead to pneumothorax or subcutaneous emphysema in severe cases. 3. Inconvenient component adjustment and storage: Drainage devices sometimes need to be suspended in different positions or temporarily used to store drainage fluid collection bags, lacking flexible and stable auxiliary suspension or placement structures. Therefore, we propose a thoracic surgical nursing anti-dislodgement drainage device to solve the above problems. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Figures 1-10 As shown, the present invention provides a drainage device for thoracic surgery nursing to prevent dislodgement, including a loading platform 1 and a silicone protective plate 9. The top of the loading platform 1 is provided with a drainage bottle 4 for storing accumulated fluid, and the drainage bottle 4 is detachable and replaceable. An infusion tube 8 is fixedly connected between the drainage bottle 4 and the silicone protective plate 9. The device is characterized in that: a fixed clamping plate 5 is symmetrically slidably connected to the outside of the loading platform 1, which can move towards the center and clamp the drainage bottle 4; a rotating frame 11 is symmetrically rotatably connected to the outside of the loading platform 1, and a hanging hook 14 is vertically slidably connected inside the rotating frame 11; an elastic bandage 19 is symmetrically fixedly connected to the outside of the silicone protective plate 9, and a first Velcro 20 and a second Velcro 25 that can be adhered to each other are fixedly connected to the outside of the elastic bandage 19; a connecting tube 10 is fixedly connected to the outside of the silicone protective plate 9, and an infusion tube connector 24 that can extend into the inside of the connecting tube 10 is fixedly connected to one end of the infusion tube 8; a rotating clamping assembly is provided on the outside of the connecting tube 10 to quickly clamp and fix the infusion tube connector 24.

[0022] It should be noted that in this embodiment, the entire device is based on the loading platform 1 and the silicone protective plate 9. The loading platform 1 is used to support and fix the core collection component, the drainage bottle 4, and is securely clamped by an adjustable fixing plate 5, ensuring that the drainage bottle 4 will not tip over when moved or accidentally touched. The rotating frame 11 and its internal height-adjustable storage hook 14 together constitute a flexible suspension system, allowing the device to be easily fixed in different positions such as hospital beds and IV stands, and its height can be adjusted as needed. The silicone protective plate 9 is used to conform to the patient's chest wall; the elastic bandage 19, the first Velcro 20, and the second Velcro 25 installed on it work together to comfortably and securely fix the silicone protective plate 9 to the patient's body. The key anti-dislodgement function is reflected in the tubing connection: the infusion tube 8 is inserted into the connecting tube 10 fixed on the silicone protective plate 9 through the infusion tube connector 24 at its end, and is quickly mechanically locked by the rotating snap-fit ​​assembly, thereby creating a secure and closed drainage channel from the patient's chest cavity to the drainage bottle 4 that is not easy to loosen.

[0023] The loading platform 1 has a storage slot 3 on its outside. A knob 2 is rotatably connected to the outside of the loading platform 1. The connecting end of the knob 2 extends into the inside of the storage slot 3 and is fixedly connected to a third threaded rod 18. The third threaded rod 18 is rotatably connected to the storage slot 3, and the fixed snap-fit ​​plate 5 is threadedly connected to the third threaded rod 18.

[0024] It should be noted that in this embodiment, rotating the knob 2 drives the third threaded rod 18, which in turn drives the fixed clamping plate 5, which is threadedly connected to the third threaded rod 18, to slide within the storage slot 3. This structure allows for easy one-handed operation, enabling the fixed clamping plate 5 to reliably clamp or release the drainage bottle 4, thus completing the quick installation, disassembly, and secure fixing of the drainage bottle and effectively preventing it from shaking or tipping over.

[0025] The inner bottom of the rotating frame 11 is fixedly connected to a first threaded rod 12, and the outer side of the rotating frame 11 is threadedly connected to a second threaded rod 13. Both the first threaded rod 12 and the second threaded rod 13 have fitting grooves 15 on their outer sides that can fit together. The storage hook 14 is fixedly connected to the top of the second threaded rod 13.

[0026] It should be noted that in this embodiment, the hook 14 is fixed to the top of the second threaded rod 13, which is threadedly connected to the rotating frame 11. Rotating the second threaded rod 13 allows it to extend or retract relative to the first threaded rod 12, thereby changing the height of the hook 14. The engaging grooves 15 provided at the ends of the first threaded rod 12 and the second threaded rod 13 increase friction when they are engaged, helping to prevent the hook from rotating and sliding down on its own after suspending a heavy object, thus ensuring height stability.

[0027] A square snap-fit ​​groove 17 is provided on the outer side of the first threaded rod 12 that is in contact with the second threaded rod 13. A square snap-fit ​​block 16 is fixedly connected to the outer side of the second threaded rod 13 that is in contact with the first threaded rod 12. The square snap-fit ​​block 16 and the square snap-fit ​​groove 17 are slidably connected.

[0028] It should be noted that, in this embodiment, the function of this structure is to prevent the second threaded rod 13 from slipping (idling) relative to the first threaded rod 12 during rotational adjustment. The square locking block 16 can only slide within the square locking groove 17 and cannot rotate relative to it, thereby ensuring that the rotational movement of the second threaded rod 13 can be accurately and smoothly converted into the linear lifting and lowering movement of the hook 14, achieving stepless height adjustment and preventing loosening.

[0029] On the other side where the first hook and loop fastener 20 and the second hook and loop fastener 25 are attached, an auxiliary hook and loop fastener is fixedly connected. An elastic rod 21 is symmetrically fixedly connected to the outside of the silicone protective plate 9. An auxiliary bandage 22 is fixedly connected to the outside of the elastic rod 21. The auxiliary bandage 22 can be attached to the auxiliary hook and loop fastener.

[0030] It should be noted that in this embodiment, auxiliary hook and loop fasteners are provided on the back of the first hook and loop fastener 20 and the second hook and loop fastener 25, which work in conjunction with the elastic rod 21 and auxiliary bandage 22 connected to the silicone plate 9. After the main fixation (elastic bandage 19 and hook and loop fasteners) is completed, the auxiliary bandage 22 can be wrapped around other parts of the body (such as the shoulder) and attached to the auxiliary hook and loop fasteners of the silicone plate 9. This structure provides additional fixation points, which can better distribute the pulling force from the infusion tube 8, prevent the silicone plate 9 from shifting, and is particularly suitable for patients with high activity levels, improving the overall stability and comfort of wearing the device.

[0031] The connecting pipe 10 is externally fixedly connected to a fixing clamping pipe 23, and the fixing clamping pipe 23 has an annular groove 29 inside, and a waterproof gasket 26 is fixedly connected inside the annular groove 29.

[0032] It should be noted that in this embodiment, a fixing clamping tube 23 is fixed to the outside of the connecting tube 10, and a waterproof gasket 26 is installed in the annular groove 29 inside the clamping tube 23. When the infusion tube connector 24 is inserted, its end will tightly abut against the waterproof gasket 26. The function of this structure is to ensure the sealing of the connection between the infusion tube connector 24 and the connecting tube 10 (and thus the patient's chest drainage tube), prevent air or liquid leakage, and maintain the negative pressure environment and hygiene of the drainage system.

[0033] The rotating latching assembly includes a storage latching block 27, a circular wheel block 281, and an elliptical block 282; The storage block 27 is symmetrically and fixedly connected to the outside of the fixed card tube 23, the round wheel block 281 is rotatably connected to the inside of the storage block 27, and the elliptical block 282 is fixedly connected to the outside of the round wheel block 281.

[0034] It should be noted that in this embodiment, the storage block 27 is fixed to the fixed locking tube 23, and contains a rotatable wheel block 281, on which an elliptical block 282 is fixed. These components together form the basis of a latching locking mechanism. The rotation of the wheel block 281 will drive the elliptical block 282 to rotate synchronously, and its elliptical shape is the key to achieving latching and unlocking.

[0035] The infusion tube connector 24 has a circular snap-fit ​​groove 30 on its outside, which can snap into the elliptical block 282. The end of the infusion tube connector 24 has a square sliding groove 31 symmetrically provided, and the circular wheel block 281 can slide between the square sliding groove 31. The end of the infusion tube connector 24 can abut against the waterproof gasket 26.

[0036] It should be noted that in this embodiment, the square sliding groove 31 on the infusion tube connector 24 accommodates the round wheel block 281, and the circular locking groove 30 accommodates the rotated elliptical block 282. During operation, the infusion tube connector 24 is inserted until it contacts the waterproof gasket 26 for sealing, and then rotated approximately 90 degrees. This rotational action drives the round wheel block 281 and the elliptical block 282 to rotate via the square sliding groove 31, causing the long axis end of the elliptical block 282 to engage with the circular locking groove 30, forming a mechanical self-locking mechanism. This structure achieves a quick and secure "insertion-rotation-locking" connection, effectively resisting axial tension and preventing the tubing from accidentally detaching due to pulling. This is the core anti-detachment function of the present invention.

[0037] The top of the drainage bottle 4 is fixedly connected to the drain pipe 6 and the vent pipe 7. The infusion pipe 8 is connected to the drain pipe 6, and the infusion pipe 8 is connected to the infusion pipe connector 24.

[0038] It should be noted that in this embodiment, the drainage bottle 4, drain tube 6, infusion tube 8, infusion tube connector 24, and connecting tube 10 are connected in sequence to form a closed fluid drainage channel from the patient's chest cavity to the drainage bottle. The vent tube 7 is used to expel gas from the bottle and maintain appropriate pressure balance within the system, which is a key component to ensure the effectiveness and safety of closed chest drainage.

[0039] A non-slip silicone pad is fixedly connected to the side of the fixing plate 5 that contacts the drainage bottle 4. It should be noted that, in this embodiment, It should be noted that in this embodiment, the drainage bottle 4 is prevented from sliding or rotating under the clamping of the fixing plate 5; at the same time, the elasticity of the silicone pad can buffer the clamping force, avoid direct contact of the hard plate causing indentations, scratches or even cracks on the surface of the drainage bottle 4, and improve the safety and reliability of the fixation.

[0040] In summary, this anti-dislodgement drainage device for thoracic surgery nursing is used by first suspending the device at a suitable height beside the bed using the hook 14. Rotate knob 2 to loosen the fixing plate 5, insert the drainage bottle 4, and then rotate knob 2 in the opposite direction to clamp the drainage bottle. Attach the silicone shield 9 to the drainage tube outlet on the patient's chest. Wrap the patient's body with the elastic bandage 19 and secure it using the first Velcro 20 and second Velcro 25. If necessary, use the auxiliary bandage 22 for further fixation. Connect the patient's chest drainage tube to the connecting tube 10 on the silicone shield 9. Insert the infusion tube connector 24 at the end of the infusion tube 8 into the fixing clamping tube 23 until it touches the waterproof gasket 26, then rotate the infusion tube connector 24 approximately 90 degrees. Rotate the elliptical block 282 to engage the circular locking groove 30, completing the connection. The orientation of the device can be adjusted by rotating the rotating frame 11, and the height of the hook 14 and the entire device can be adjusted by rotating the second threaded rod 13. When the drainage bottle needs to be replaced, simply rotate knob 2 to loosen the retaining plate 5 and remove it. When the patient connection needs to be disconnected, rotate the infusion tubing connector 24 in the opposite direction approximately 90 degrees to unlock it and then pull it out.
