Description

Disposable suction tube

technical field

The utility model relates to the field of medical equipment, in particular to a disposable sputum suction tube.

Background technique

At present, the sputum suction tube used clinically generally adopts a flexible tube. One end of the flexible tube is a sputum suction tube with a bottom hole and a side hole, and the other end of the flexible tube is a connecting end. It is connected with the absorber, and then the suction end of the hose is inserted into the patient's respiratory tract, and the sputum is sucked out by the negative pressure of the absorber, which can suck out most of the sputum, but there are often secretions such as sputum remaining In the mouth, between the teeth, on the tongue coating, etc., the existing sputum suction tube cannot clean the mouth thoroughly, causing the growth and reproduction of bacteria, which greatly increases the chance of oral infection. Some use cotton balls to scrub, and after cleaning, a negative pressure device is needed It is sucked out, troublesome to operate, and repeated operation also brings misery and inconvenience to patient. The existing sputum suction tube has a single pressure, the pressure cannot be adjusted, and cannot meet the needs of different patients.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a disposable sputum suction tube includes a tube body 1, a spherical end 2 is provided at the front end of the tube body, and two mutually isolated sputum suction chambers 3 and spray nozzles are arranged symmetrically inside the spherical end 2. The water cavity 4, the outer wall of the hemisphere close to the sputum suction cavity is evenly distributed with suction holes 5 connected with the sputum suction cavity, and the bristles 6 are evenly distributed on the outer wall of the hemisphere close to the water spray cavity on the spherical end, the spherical end On the outer wall of the hemisphere close to the water spray chamber, spray holes 7 connected with the water spray chamber are evenly distributed. The first lumen 8 and the second lumen 9 which are isolated from each other are arranged in the pipe body. The front end of the first lumen 8 It communicates with the sputum suction chamber 3, the front end of the second lumen 9 communicates with the water spray chamber 4, and a connecting pipe 10 is arranged on the side wall of the rear part of the pipe body, and the front end of the connecting pipe 10 communicates with the rear end of the second lumen 9, The rear end of the connecting pipe 10 is connected with a syringe 11, through which the cleaning liquid can be injected into the connecting pipe 10, and then the cleaning liquid enters the water spray chamber 4 through the second lumen 9, and then sprays out through the spray hole 7, and then Brush your mouth with the bristles. The back end of the tube body is connected with a sputum storage bottle 12 which communicates with the sputum suction cavity. The sputum storage bottle 12 is provided with a negative pressure generator 24, which makes the sputum storage bottle 12 generate negative pressure, so that the sputum can pass through The sputum suction hole 5 enters the sputum suction cavity 3, and then enters the sputum storage bottle 12 through the first lumen 8 for collection.

A pressure regulating port 13 communicating with the first lumen 8 is opened on the side wall of the rear end of the pipe body, and a vertically arranged air pipe 14 is connected to the pressure regulating port 13, and a horizontally arranged air pipe 14 is arranged on the upper port of the air pipe 14. Adjusting tube 15, the middle side wall of the adjusting tube 15 is provided with a vent hole 16 communicating with the upper port of the venting tube, the regulating tube is provided with a stopper 17 that is sealingly and slidingly matched with the inner wall of the regulating tube, and the outer peripheral wall of the stopper 17 is covered with A sealing sleeve is provided, and the sealing sleeve makes the sealing between the stopper 17 and the regulating tube 15 good. One end of the regulating tube 15 is provided with a sealing end cover 18, and the other end of the regulating tube 15 is provided with an opening. The stopper 17 and the sealing end A stage clip 19 is connected between the covers 18, and the stage clip 19 can drive the stopper to move towards the opening end of the regulating pipe so that the stopper is positioned between the upper port of the vent pipe and the opening of the regulating pipe, so that the upper opening of the vent pipe can be blocked. The connection between the port and the opening of the regulating tube, the stopper 17 is fixed with a push rod 20 protruding from the opening of the regulating tube on the side wall away from the clip spring, when the negative pressure generator 24 starts to work, the first lumen Negative pressure is generated in 8, so that sputum enters the sputum suction chamber 3 through the sputum suction hole 5. At this time, the negative pressure in the first lumen 8 is the largest. When spraying cleaning liquid into the oral cavity through the spray hole 7, a brush is needed For scrubbing, the less negative pressure in the first lumen 8, the better, so as to avoid cleaning liquid being sucked away during scrubbing and affecting the cleaning effect, the stopper 17 can be driven towards the sealing end cap by pushing the push rod 20 direction sliding, so that the stopper 17 is separated from the vent hole 16, so that the vent hole 16 of the vent pipe will communicate with the opening of the regulating tube 15 to realize communication with the outside world, so that the first lumen 8 is the same as the outside world. The ventilation hole 16 is completely separated, and the negative pressure in the first lumen 8 is the smallest at this time, and only a small amount of cleaning liquid will enter the sputum suction cavity 3 through the sputum suction hole 5, which does not affect the scrubbing operation of the brush. When the push rod 20 is opened, the stopper 17 will move to the opening end of the adjustment tube under the elastic force of the compression spring 19, thereby blocking the communication between the upper port of the ventilation tube and the opening of the adjustment tube. At this time, the negative pressure in the first lumen 8 When it becomes larger, all the cleaning liquid can be sucked out, so that the oral cavity is cleaned thoroughly.

A guide rod 21 arranged horizontally is fixed on the inner side wall of the sealing end cover, and the compression spring is sleeved on the guide rod. A guide hole is provided in the stopper 17 to seal and slide with the guide rod. The end of the rod 21 away from the sealing end cap passes through the guide hole and extends to the opening of the regulating tube to fix the limit block 22. The guide rod 21 plays a guiding role on the block 17, so that the block runs smoothly and ensures that the block and the adjustment The sealing effect of the inner wall of the pipe 15 is good, and the limit block 22 can prevent the block 17 from detaching from the guide rod 21, so as to ensure the normal operation of the block.

The push rod is U-shaped, which is convenient for medical staff to operate. The middle side wall of the push rod is provided with a perforation 23 for the stopper to pass, so that the stopper can be prevented from affecting the movement of the push rod.

The bottom of the sputum storage bottle is provided with a sputum discharge pipe 25, and the sputum discharge pipe 25 is provided with a control valve, which facilitates the discharge of sputum and is convenient for centralized processing.
