AI Technical Summary
Existing chest drainage tubes are difficult to clamp quickly during use, which can easily lead to fluid backflow and infection. Frequent clamping can also cause tube breakage. Tilting the water seal bottle can cause gas backflow. Existing rolling switches are prone to accidental activation, resulting in unstable opening and closing.
A switch for a chest drainage tube was designed, comprising a cylinder, a support, a column, and a horizontal tube. Quick closure is achieved by inserting the column into the horizontal tube for plugging or threaded connection. Combined with a rubber sleeve and a raised edge structure, a seal and stable connection are ensured.
It enables rapid and stable closure of the drainage path, avoids liquid leakage and infection, prevents accidental activation, enhances connection stability, prevents detachment, and provides a visual display of the switch status.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a switch for a chest drainage tube. BACKGROUND
[0002] The chest closed drainage is to place one end of a drainage tube into a chest cavity and connect the other end to a water seal bottle at a lower position, so as to discharge the accumulated gas and liquid in the chest cavity, so that the lung tissue is re-expanded to restore the function. As a treatment method, the chest closed drainage is widely applied to the drainage of hemopneumothorax, pneumothorax and empyema and post-thoracotomy, and plays a very important role in the treatment of diseases. When the water seal bottle needs to be replaced, a hemostat is used to clamp the drainage tube to prevent gas from entering the pleural cavity, and then the water seal bottle is replaced. However, the clamping of the drainage tube by the hemostat has the following problems: first, when the drainage liquid backflows in the normal use process, it is often difficult to quickly and conveniently clamp the drainage tube; second, if the clamping is frequent, the drainage tube is easily broken, which causes the gas to enter the chest cavity and causes complications such as pneumothorax; third, when the patient is drained, the water seal bottle is easily tilted during the process of passing through a bed, getting on and off a bed, walking and the like, which causes the chest gas or liquid to flow back to the chest cavity, so that the patient is infected again. In addition, some use a rolling switch for infusion on the drainage tube, which improves the response speed, but is easy to be accidentally touched, which causes the switch to be accidentally opened or closed, so the utility model discloses a switch for a chest drainage tube. SUMMARY

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] Example 1:
[0031] like Figure 1 As shown, this embodiment provides a switch for a chest drainage tube, including a cylindrical body 1. A bracket 2 is fixedly installed inside the cylindrical body 1, and a column 3 is fixedly installed on the bracket 2. The bracket 2 can support the column 3 without affecting the internal communication of the cylindrical body 1. A horizontal tube 4 is provided on one side of the column 3.
[0032] In this embodiment, a retaining ring 5 is fixedly installed on the inner wall of the cylinder 1, and a first protruding edge 6 is provided at the end of the horizontal tube 4 located on one side inside the cylinder 1.
[0033] In this embodiment, the diameter of the column 3 on the side away from the horizontal tube 4 gradually increases.
[0034] In this embodiment, the horizontal tube 4 is provided with a second protruding edge 7.
[0035] In this embodiment, an annular mounting plate 10 is fixedly installed on one side of the cylinder 1, and a connecting pipe 11 is fixedly installed on the end of the horizontal pipe 4 located on the outside of the cylinder 1 and on the mounting plate 10 respectively. The connecting pipe 11 is a tapered pipe, which allows the drainage pipe to be easily inserted into the connecting pipe 11. Several evenly arranged third protrusions 8 are provided on the connecting pipe 11.
[0036] In this embodiment, a rubber sleeve 9 is fitted around the outer periphery of the horizontal tube 4. One side of the rubber sleeve 9 is fixedly connected to the outer periphery of the second convex edge 7, and the other side of the rubber sleeve 9 is fixedly connected to the outer periphery of the cylinder 1.
[0037] When using this device, if it is necessary to close the drainage tube and replace the water seal bottle, by holding the second protruding edge 7 and pushing the horizontal tube 4 into the cylinder 1, the column 3 inside the cylinder 1 is inserted into the horizontal tube 4, blocking the end of the horizontal tube 4. This allows the outer circumference of the column 3 to fit tightly against the inner wall of the horizontal tube 4, enabling quick and convenient clamping of the drainage tube and effectively closing the drainage path. In addition, in the event of sudden changes in patient movement or water seal bottle position, this device can quickly close the drainage path, preventing backflow of drainage fluid due to untimely clamping of the drainage tube, effectively reducing the chance of pleural infection. Furthermore, the switch for pleural drainage tubes described in this invention can also be used in medical tubing such as abdominal drainage tubes, pelvic drainage tubes, gastrointestinal decompression tubes, and urinary catheters.
[0038] Example 2:
[0039] like Figure 2 As shown, this embodiment provides a switch for a chest drainage tube, the structure of which is roughly the same as that of Embodiment 1, except that: in this embodiment, the inner thread of the cylinder 1 is provided, and the corresponding outer thread is provided on the horizontal tube 4.
[0040] In this embodiment, the diameter of the end of the cylinder 1 away from the horizontal tube 4 gradually decreases.
[0041] In this embodiment, the horizontal tube 4 is marked on the side near the second convex edge 7.
[0042] In this embodiment, the drain tube is switched on and off by means of the interaction between the internal thread of the cylinder 1 and the external thread on the horizontal tube 4. The drain path is opened and closed by rotating the horizontal tube 4. This method allows for quick and convenient use while locking the cylinder 1 and the horizontal tube 4 through the threaded connection, preventing changes in the current use state due to accidental contact and affecting normal use, thus providing an anti-accidental contact effect.
[0043] The above description is merely the preferred embodiments of the present application and the explanation of the technical principles applied. It should be understood by those skilled in the art that the scope of the application involved in the present application is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by the combinations of the above technical features or equivalent features without departing from the inventive concept.
