Description

Technical Field

[0001] This utility model relates to the field of cardiothoracic surgery technology, specifically to a cardiothoracic surgery nursing device to prevent dislodgement of drainage fluid. Background Technology

[0002] Cardiothoracic surgery is a medical specialty that treats diseases of the chest (including diseases of the heart, lungs, esophagus, chest wall, etc.). After cardiothoracic surgery, such as heart surgery or lung surgery, it is often necessary to place a chest drainage tube to drain accumulated blood, fluid, or air, in order to promote healing and prevent infection.

[0003] Patent CN213219701U discloses a cardiothoracic surgery anti-reflux drainage device, comprising a sealed bottle body. The inner cavity of the bottle body is divided into two airtight, independent effusion chambers and a water-seal chamber. A drainage tube is connected to the top of the effusion chamber. A connecting tube is provided at the top of the bottle body, connecting the effusion chamber and the water-seal chamber. A water-seal tube is provided in the water-seal chamber, and the top of the water-seal tube is connected to the connecting tube. An expansion section is provided on the water-seal tube, and an exhaust port is provided at the top of the water-seal chamber. This drainage device prevents effusion from refluxing into the pleural cavity through the drainage tube during drainage. Furthermore, the expansion section on the water-seal tube, positioned above the fluid level, can store some of the aspirated saline solution when the negative pressure in the pleural cavity is too high, creating a buffer effect. This prevents saline solution from easily entering the effusion chamber and causing saline loss, thus avoiding the problem of the saline solution level falling below the bottom of the water-seal tube after saline loss, and further preventing outside air from entering the pleural cavity.

[0004] However, the aforementioned drainage device still has the following problems in actual use:

[0005] During the use of drainage devices, the drainage tube may accidentally dislodge while the patient is active or unconscious, leading to problems such as wound infection, hematoma formation, and pneumothorax. The connection between the existing drainage tube and drainage bag is usually fixed by inserting and friction, which has low fixation strength and a high probability of dislodgement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cardiothoracic surgery nursing anti-dislodgement drainage device to solve the problem that the drainage tube and drainage bag are currently fixed only by friction, which leads to easy dislodgement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cardiothoracic surgery nursing anti-dislodgement drainage device, comprising a drainage bag, two inlet and outlet tubes installed on the upper end of the drainage bag, a drainage tube matched with the inlet and outlet tubes, and a plug installed at the front end of the inlet and outlet tubes. The upper surface of the inlet and outlet tubes is provided with an insertion hole. The outer wall of the plug is slidably connected to the inner wall of the insertion hole. The inner wall of the insertion hole is provided with several alignment openings. The bottom surface of each of the several alignment openings is connected to a squeezing component. The end of the drainage tube near the plug is connected to several anti-dislodgement components. The several anti-dislodgement components are respectively located in the several alignment openings, and the lower ends of the several anti-dislodgement components are respectively matched with the several squeezing components.

[0008] Furthermore, a hanging opening is provided at the end of the alignment port near the extrusion component, and the end of the anti-detachment component near the extrusion component matches the hanging opening.

[0009] Furthermore, the anti-detachment component includes an L-shaped rod and a hook. The side wall of the L-shaped rod is fixedly connected to the outer wall of the drainage tube near the plug end. The lower end of the L-shaped rod is fixedly connected to one end of the hook. The outer wall of the L-shaped rod is slidably connected to the inner wall of the alignment opening. The outer wall of the hook is slidably connected to the inner wall of the hanging opening. The bottom surfaces of both the L-shaped rod and the hook are matched with the squeezing component.

[0010] Furthermore, the bottom surface of the alignment port is provided with several spring holes, and the lower end of the extrusion assembly is located within several spring holes.

[0011] Furthermore, the extrusion assembly includes a top plate and several push springs. The upper surface of the top plate abuts against the bottom surface of the L-shaped rod and the hook. The side wall of the top plate is slidably connected to the inner wall of the alignment opening. The bottom surface of the top plate is fixedly connected to the upper ends of several push springs. The lower ends of several push springs are respectively fixedly connected to the inner walls of several spring holes.

[0012] Furthermore, the height of the compressed spring should not exceed the height of the spring hole, and the natural rebound height of the spring should not be less than the height between the upper surface of the top plate and the hanging opening.

[0013] Furthermore, a positioning plate is fitted and fixedly connected to the outer wall of the drainage tube near the plug end, and the bottom surface of the positioning plate abuts against the upper surface of the inlet and outlet tubes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of anti-dislodgement drainage device for cardiothoracic surgery uses an alignment port inside the insertion hole of the drainage bag inlet / outlet tube, a squeezing component inside the alignment port, and an anti-dislodgement component on the outside of the drainage tube. When medical staff drain the drainage tube for cardiothoracic surgery patients, they can insert the plug of the drainage tube into the insertion hole and then use the anti-dislodgement component to fix the plug in the alignment port. This solves the problem that the drainage tube and drainage bag are currently fixed by friction alone, which makes them prone to falling off. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 A cardiothoracic surgical nursing anti-dislodgement drainage device includes a drainage bag 1, two inlet and outlet tubes 2 installed on the upper end of the drainage bag 1, a drainage tube 3 matched with the inlet and outlet tubes 2, and a plug 9 installed at the front end of the inlet and outlet tubes 2. The upper surface of the inlet and outlet tubes 2 is provided with a socket 21. The outer wall of the plug 9 is slidably connected to the inner wall of the socket 21. The inner wall of the socket 21 is provided with a plurality of alignment openings 22. The bottom surface of each of the plurality of alignment openings 22 is connected to a squeezing component. The end of the drainage tube 3 near the plug 9 is connected to a plurality of anti-dislodgement components. The plurality of anti-dislodgement components are respectively located in the plurality of alignment openings 22, and the lower ends of the plurality of anti-dislodgement components are respectively matched with the plurality of squeezing components.

[0023] This utility model discloses a cardiothoracic surgery nursing anti-dislodgement drainage device, which is structurally similar to existing cardiothoracic surgery nursing anti-dislodgement drainage devices, such as the cardiothoracic surgery anti-reflux drainage device disclosed in patent announcement number CN213219701U. Figures 1 to 4 As shown, when medical staff drain a cardiothoracic surgery patient through the drainage tube 3, they only need to insert the plug 9 of the drainage tube 3 into the socket 21, and then fix the plug 9 in the alignment port 22 through the anti-dislodgement component. At this time, the plug 9 and the drainage tube 3 can be fixed by the anti-dislodgement component and the alignment port 22, thus solving the problem of easy dislodgement caused by fixing by friction alone.

[0024] like Figure 2 and Figure 3 As shown, the end of the alignment port 22 near the extrusion assembly has a hanging port 23, and the end of the anti-detachment assembly near the extrusion assembly matches the hanging port 23.

[0025] More specifically, by setting the hanging port 23, the connectivity of the anti-detachment component can be increased firstly; secondly, after the anti-detachment component is inserted into the alignment port 22, it can be rotated again to lock the anti-detachment component into the hanging port 23, thereby achieving double fixation between the drainage tube 3 and the inlet / outlet tube 2 through the anti-detachment component, thus making the fixation more stable.

[0026] like Figure 4 As shown, the anti-detachment component includes an L-shaped rod 5 and a hook 6. The side wall of the L-shaped rod 5 is fixedly connected to the outer wall of the drainage tube 3 near the plug 9. The lower end of the L-shaped rod 5 is fixedly connected to one end of the hook 6. The outer wall of the L-shaped rod 5 is slidably connected to the inner wall of the alignment port 22. The outer wall of the hook 6 is slidably connected to the inner wall of the hanging port 23. The bottom surfaces of both the L-shaped rod 5 and the hook 6 are matched with the extrusion component.

[0027] More specifically, after inserting the plug 9 of the drainage tube 3 into the alignment port 22, the bottom surfaces of the L-shaped rod 5 and the hook 6 will first press against the top of the squeezing assembly. Then, continue to press down on the L-shaped rod 5 and the hook 6, pressing down the squeezing assembly together. After that, manually rotate the drainage tube 3 slightly to one side. While the drainage tube 3 is rotating, the L-shaped rod 5 and the hook 6 will rotate together. When the hook 6 rotates to the position of the hanging port 23, it cannot continue to rotate due to the obstruction of the inner wall. Then, release the hand pressing the drainage tube 3. At this time, the squeezing assembly lacks pressure from above and will instantly push the L-shaped rod 5 and the hook 6 upward together. At this time, the hook 6 will be inserted into the hanging port 23, thus completing the connection and fixation between the L-shaped rod 5 and the hook 6 and the inlet / outlet tube 2.

[0028] Furthermore, because the hook 6 protrudes into the hanging opening 23, and because of the upper pressure of the squeezing component, a double limit is achieved, which can greatly improve stability and reduce the probability of falling off.

[0029] like Figure 2 and Figure 3 As shown, the bottom surface of the alignment port 22 is provided with several spring holes 24, and the lower end of the extrusion assembly is located in several spring holes 24.

[0030] More specifically, by providing spring holes 24, the extrusion assembly can be supported and stored, while also reducing the external space occupied by the extrusion assembly.

[0031] like Figure 4As shown, the compression assembly includes a top plate 7 and several push springs 8. The upper surface of the top plate 7 abuts against the bottom surface of the L-shaped rod 5 and the hook 6. The side wall of the top plate 7 is slidably connected to the inner wall of the alignment opening 22. The bottom surface of the top plate 7 is fixedly connected to the upper ends of the push springs 8, and the lower ends of the push springs 8 are respectively fixedly connected to the inner walls of the spring holes 24. The height of the push springs 8 after compression is not greater than the height of the spring holes 24, and the natural rebound height of the push springs 8 is not less than the height between the upper surface of the top plate 7 and the hanging opening 23.

[0032] More specifically, when the L-shaped rod 5 and hook 6 are pressed down, the L-shaped rod 5 and hook 6 will press the top plate 7 down, and when the top plate 7 descends, it will push and compress several push springs 8; after the hook 6 is rotated to align with the hanging opening 23, the drainage tube 3 is released, and the push springs 8, lacking the pressure from above, will push the top plate 7 upward, which in turn can push the L-shaped rod 5 and hook 6 upward together until the hook 6 enters the hanging opening 23 and stops.

[0033] like Figure 1 and Figure 4 As shown, a positioning piece 4 is fitted and fixedly connected to the outer wall of the drainage tube 3 near the plug 9, and the bottom surface of the positioning piece 4 abuts against the upper surface of the inlet / outlet tube 2.

[0034] More specifically, by setting the positioning piece 4, medical staff can more intuitively understand that the plug 9 is inserted into the correct position, and then start rotating the drainage tube 3.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
