[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Please see Figures 1 to 6This utility model discloses a medical drainage tube device comprising a drainage tube 100, a locking assembly 200, an external connecting tube 120, a flushing assembly 300, a negative pressure drainage connector 130, a effusion bag 140, and a flushing channel 150. The drainage tube 100 has a retractable corrugated drainage tube 110 in its middle portion. The flushing channel 150 is located on the inner wall of the drainage tube 100, and a corrugated flushing channel 151 is located in its middle portion. The locking assembly 200 is located on the outside of the retractable corrugated drainage tube 110. The external connecting tube 120 is located on the side of the drainage tube 100 and communicates with the flushing channel 150. The flushing assembly 300 is connected to the external connecting tube 120. The effusion bag 140 is connected to one end of the drainage tube 100, and the negative pressure drainage connector 130 is connected to the drainage tube 100.

[0025] The retractable corrugated drainage tube 110 can be extended and shortened to meet the need to change the length of the drainage tube 100. At the same time, since the middle part of the flushing channel 150 is a corrugated flushing channel 151, it can also change with the length of the retractable corrugated drainage tube 110. The locking component 200 can limit the extension and shortening of the retractable corrugated drainage tube 110. The flushing component 300 and the flushing channel 150 meet the need to flush the inside of the drainage tube 100, avoiding the accumulation of liquid that may block the drainage tube 100 and cause poor drainage effect, and preventing corrosive liquid in the accumulated liquid from corroding the inner wall of the drainage tube 100. The negative pressure drainage connector 130 is provided to facilitate the quick connection of the negative pressure drainage device and improve the drainage efficiency.

[0026] It is worth noting that the above-mentioned negative pressure drainage device is a conventional negative pressure drainage device, and its working principle will not be elaborated here.

[0027] Furthermore, when a patient needs drainage using a medical drainage tube device of this utility model, firstly, the nursing staff adjusts the drainage tube 100 to a suitable length according to the thickness of the patient's abdominal fat, using the cooperation of the retractable corrugated drainage tube 110 and the locking component 200. Then, the drainage tube 100 is inserted into the area of ​​the patient's abdomen that needs drainage. The negative pressure drainage device is connected to the negative pressure drainage connector 130, and the fluid in the patient's abdomen is drained into the fluid bag 140. If the patient's fluid is viscous or contains corrosive liquid, the protective cap 121 on the external tube 120 is removed, and the flushing component 300 is connected to the external tube 120. The flow rate of the saline solution is adjusted by the flow rate regulator 330 and flushed through the flushing channel 150 to rinse the viscous fluid at the drainage site, avoiding blockage at the drainage site and diluting the corrosive fluid at the drainage site.

[0028] In this embodiment, the locking assembly 200 includes: a sleeve 210, an elastic element 220, and a locking block 230. The sleeve 210 is disposed on the outside of the retractable corrugated drainage tube 110, and the rear side of the sleeve 210 is fixedly disposed on the drainage tube 100. A plurality of first locking protrusions 211 are provided on the rear inner wall of the sleeve 210. The elastic element 220 is fixedly disposed on the front end of the sleeve 210. The locking block 230 is threadedly connected to the sleeve 210 and the elastic element 220. A plurality of second locking protrusions 221 are provided on the inner wall of the locking block 230.

[0029] The first locking protrusion 211 and the second locking protrusion 221 limit the length change of the retractable corrugated drainage tube 110. When the elastic element 220 is not subjected to external force, it is in an open state, meaning the second locking protrusion 221 does not contact the retractable corrugated drainage tube 110 and cannot provide a locking function. When the elastic element 220 is subjected to external force, it is in a closed state, meaning the second locking protrusion 221 contacts the retractable corrugated drainage tube 110 and provides a locking function. When the caregiver needs to change the length of the drainage tube 100, the locking block 230 is fully screwed into the sleeve 210, and the elastic element 220 returns to its original position under elastic action. In the open state, the retractable corrugated drainage tube 110 is released from its locked state at the end near the second locking protrusion 221. Medical staff stretch the retractable corrugated drainage tube 110 to a suitable length, and then screw the locking block 230 onto the elastic member 220. The elastic member 220 is subjected to external pressure and changes from the open state to the closed state. The second locking protrusion 221 contacts the retractable corrugated drainage tube 110 and plays a locking role. Since the rear side of the sleeve 210 is fixedly set on the drainage tube 100, the first locking protrusion 211 always plays a locking role. The length of the retractable corrugated drainage tube 110 can only be changed from the end near the second locking protrusion 221.

[0030] In this embodiment, the external tube 120 is connected to the drainage tube 100 through the flushing channel 150. A protective cover 121 is provided on the top of the external tube 120, and the protective cover 121 is threadedly connected to the top of the external tube 120. The flushing assembly 300 includes: a saline bag 310, a flushing tube 320, a flow rate regulator 330, and a flushing frame 340. One end of the flushing tube 320 is connected to the saline bag 310, and the other end of the flushing tube 320 is provided with a connecting thread. The flow rate regulator 330 is located in the middle section of the flushing tube 320, and the saline bag 310 is located on the flushing frame 340.

[0031] When the drainage tube 100 is blocked by viscous fluid or contains corrosive liquid, medical staff first place the saline bag 310 on the rinsing rack 340, then remove the protective cover 121, connect the rinsing tube 320 to the external tube 120, and adjust the flow rate of the saline through the flow rate regulator 330. The saline is used to dilute the viscous and corrosive fluid and drain it from the drainage tube 100 to ensure drainage effect. The protective cover 121 serves as a dustproof cover to prevent dust from entering the drainage tube 100 when the cleaning components are not working, thus avoiding secondary infection of the patient.

[0032] This medical drainage tube device includes a drainage tube 100, a locking assembly 200, an external connecting tube 120, a flushing assembly 300, a negative pressure drainage connector 130, a effusion bag 140, and a flushing channel 150. The drainage tube 100 has a retractable corrugated drainage tube 110 in its middle portion. The flushing channel 150 is located on the inner wall of the drainage tube 100, and its middle portion has a corrugated flushing channel 151. The locking assembly 200 is located on the outside of the retractable corrugated drainage tube 110. The external connecting tube 120 is located on the side of the drainage tube 100 and communicates with the flushing channel 150. The flushing assembly 300 is connected to the external connecting tube 120. The effusion bag 140 is connected to the drainage tube 100. One end of the tube is connected to the negative pressure drainage connector 130, which is connected to the drainage tube 100. The retractable corrugated drainage tube 110 can be extended and shortened to meet the need to change the length of the drainage tube 100, so that the whole device is in a suitable spatial position and will not affect the patient's later rehabilitation activities. The locking component 200 can limit the extension and shortening of the retractable corrugated drainage tube 110. The flushing component 300 can meet the need to flush the drainage tube 100 to avoid the accumulation of fluid blocking the drainage site and causing poor drainage effect. At the same time, it can also dilute the corrosive fluid at the drainage site and prevent the corrosive liquid in the fluid from damaging the inner wall of the drainage tube 100. The negative pressure drainage connector 130 is set to facilitate the quick access of the negative pressure drainage device and improve the drainage efficiency.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
