Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically a suction tube connection pipe flushing device. Background Technology
[0002] Maintaining a patent airway and correcting hypoxia in critically ill patients, establishing an artificial airway is a common clinical practice during the process of improving their ventilation. Timely and effective removal of respiratory secretions is crucial in the management of artificial airways, and suctioning plays a vital role in this process. Currently, integrated suctioning systems that combine fluid collection, flushing, and fixation simplify the suctioning procedure, accelerate clinical procedures, and offer high safety.
[0003] A device that combines liquid storage, rinsing, and fixing functions, such as Figure 1 As shown, the reservoir 1 contains 500ml of 0.9% sodium chloride injection solution (i.e., flushing solution). After the suctioning procedure (the sputum in the suction tube will also enter the connecting pipe connected to the suction tube, causing sputum to adhere to the inner wall of the connecting pipe), the suction tube is removed from the connecting pipe and discarded. The connecting pipe is then connected to the flushing port 6 (which has a second cap 61 on the upper side, and must be opened when connecting the pipe). The negative pressure suction of the negative pressure device connected to the connecting pipe causes the liquid in the reservoir 1 to enter the connecting pipe and flush the inner wall of the connecting pipe. When the flushing solution is insufficient, 500ml of liquid can be added at once through the water inlet 5 (which has a first cap 51 on the top, and must be opened when adding liquid). After flushing, the fixing cylinder 100 with the upper opening is inserted to fix the connecting pipe so that the connecting pipe is not easily detached. The hook 13 can be easily and conveniently hung on the side of the bedside table drawer, on the ICU pendant, bed rail, or other convenient locations for medical staff to operate.
[0004] The above-mentioned equipment combines liquid storage, rinsing, and fixing. Its disadvantage is that the liquid storage bottle 1 is a one-piece structure, which cannot be disinfected and reused after cleaning the connecting pipes. It must be discarded directly, resulting in increased costs. Utility Model Content

A detachable top cover 2 is provided on the top. Notches 12 are recessed downwards on the front and rear side plates of the housing 1A. Vertical hooks 13 are provided at the left and right ends of the rear outer surface of the housing 1A. A transparent bag 3 is located below the top cover 2. The bag 3 is also a rectangular parallelepiped with an open top, and its opening is fixedly connected to the inner top surface of the top cover 2 (the inner top surface of the top cover 2, i.e., the bottom surface of the top cover 2, and the opening of the bag 3 are heat-fused together). Vertical graduations 31 are also provided on the outer surface of the bag 3. The top cover 2 has a water inlet 5 on one side of the top. A first cover 51 is detachably attached to the upper side of the water inlet 5 (connected to the outer wall of the water inlet 5 by a flexible connector (not visible) to prevent the cover from being lost). A rinsing port 6 is provided on the top cover 2 on one side of the water inlet 5. A second cover 61 is provided on the top of the rinsing port 6 (connected to the outer wall of the rinsing port 6 by a flexible connector (not visible) to prevent the cover from being lost). A rinsing tube 8 extending into the bag body 3 is fixedly connected to the bottom of the rinsing port 61 (the liquid in the bag body 3 will enter the rinsing tube 8). A horizontal controllable pressure port 7 is also provided on one side of the rinsing port 61. A plug 71 is detachably attached to the outer port of the controllable pressure port 7 (connected to the outer wall of the controllable pressure port 7 by a flexible connector (not visible) to prevent the plug from being lost).
[0027] The connecting part between the top cover 2 and the left and right sides of the shell 1 is provided with a buckle cover part 4, which comprises a vertical rectangular frame 41, the vertical rectangular frame 41 is bent in the middle position to form a vertical part 42 and a horizontal part 43 towards the top cover 2, the bottom of the vertical part 42 (on the horizontal bar) is rotatably sleeved with a first sleeve 44, the bottom of the first sleeve 44 is provided with a fixed plate 45, the fixed plate 45 is fixedly connected with the shell 1A by a rivet 46, the inner end of the horizontal part 43 (on the horizontal bar) is fixedly sleeved with a second sleeve 47, and the upper surface of the top cover 2 is further embedded with an arc-shaped groove 21 matched with the second sleeve 47, when the rectangular frame 41 is buckled, the second sleeve 47 is just clamped into the arc-shaped groove 21.

[0032] In use, the top cover 2 can be separated from the shell 1A, and the shell 1A can be retained later (only the top cover 2 part is thrown away, together with the attached parts including the bag body 3, the water inlet 5, the flushing port 6, the flushing pipe 8), which avoids waste of materials. The gap 12 is beneficial to the balance of the air pressure inside and outside the shell 1A, and the hook 13 is convenient for hanging the shell 1A (which can be easily hung on the bedside cabinet drawer edge, ICU tower, bed rail, etc. for convenient operation of medical staff). The flushing liquid (sterilized water for injection) can be stored in the bag body 3, the shell 1A and the bag body 3 are both transparent structures, and the bag body 3 is provided with a scale, which is convenient for the staff to observe the capacity of the flushing liquid. By opening the first buckle cover 51 and the second buckle cover 61, the flushing liquid can be easily injected through the water inlet 5, the flushing port 6 is convenient for connecting pipeline connection, and by opening the plug 71, the right opening of the controllable pressure port 7 can be blocked by hand, and the size of the negative pressure can be controlled by the plugging area.
[0033] Specifically, after the sputum suction tube is pulled off from the connecting pipe and discarded, the connecting pipe is connected with the upper end of the flushing port 6, and the inner wall of the connecting pipe is flushed by the negative pressure suction effect of the negative pressure device connected by the connecting pipe. The flushing device is replaced every 24 hours, the top cover 2 is opened, the top cover 2 is discarded together with the attached parts (the water injection port 5, the flushing port 6, the flushing pipe 8 and the bag body 3), and the shell 1A can be used again after disinfection, so that the waste of materials is reduced.
