The utility model provides a disposable quantitative medicinal suction tube 4 head (hereinafter referred to as the suction tube 4 head) for quantitatively sucking gargle liquid medicine in an infusion bottle or an infusion bag 20, and the embodiment takes the connection of the suction tube 4 head and the infusion bag 20 as an example for explanation.

As shown in fig. 1, in a preferred embodiment of the present invention, the suction tube 4 comprises a liquid inlet tube 1 capable of being inserted into an infusion bag 20, a quantitative air bag 3 capable of containing a liquid medicine and fixedly connected to and communicated with the liquid inlet tube 1, and a suction tube 4 fixedly sealed and connected to the quantitative air bag 3 for sucking the liquid medicine. The liquid inlet pipe 1 is provided with a reflux valve 2 which only allows the liquid medicine to flow from the liquid inlet pipe 1 to the quantitative air bag 3, and the reflux valve 2 is arranged in the infusion bag 20 or outside the infusion bag 20.

Wherein, the quantitative gasbag 3 is located outside the infusion bag 20, and the quantitative gasbag 3 has the resilience, and preferred quantitative gasbag 3 is made by transparent rubber or transparent silica gel. The suction pipe 4 partially extends into the quantitative air bag 3, preferably, the inlet of the suction pipe 4 extends to the bottom of the quantitative air bag 3, and the suction nozzle of the suction pipe 4 is positioned outside the quantitative air bag 3, so that a patient can suck the liquid medicine in the quantitative air bag 3 through the suction nozzle conveniently.

When the quantitative air bag mouth washing device is used, a user squeezes the quantitative air bag 3 by hands to discharge air in the quantitative air bag 3, then the suction pipe suction nozzle 41 is closed, the hand squeezing the quantitative air bag 3 is released, liquid medicine in the infusion bag 20 enters the quantitative air bag 3 through the liquid inlet pipe 1 under the action of negative pressure of the quantitative air bag 3, the quantitative air bag 3 is recovered to an initial state, and the user sucks the liquid medicine in the quantitative air bag 3 through the suction pipe suction nozzle 41 to wash the mouth. When people suck the liquid medicine to rinse the mouth, the quantitative air bag 3 is shrunken due to the action of the negative pressure, and when the quantitative air bag 3 is communicated with the external atmosphere through the suction pipe and the suction nozzle 41, the quantitative air bag 3 is restored to the initial state. When the quantitative air bag 3 is extruded each time, the quantitative air bag 3 is stopped when being attached to the wall of the suction pipe 4, and the quantitative liquid medicine entering the quantitative air bag 3 is ensured each time when being extruded, for example, the quantitative liquid medicine entering the quantitative air bag 3 is 10mL when being extruded, the quantitative liquid medicine amount can be ensured to be 10mL each time, and the quantitative function is achieved.

In this embodiment, the suction nozzle 41 may be closed by squeezing the pipette 4 to expose the outside of the quantitative air bag 3 or by closing the suction nozzle 41 with a stopper 5. When the suction pipe 4 is tightly extruded, the part of the suction pipe 4 exposed outside the quantitative air bag 3 can be prolonged, and the hands of people are not directly contacted with the suction nozzle; when the stopper 5 is used to seal the pipette tip 41, the stopper 5 may be fixed to the pipette 4 by a flexible band or may be provided separately.

In another preferred embodiment, a straw cover 6 capable of covering the straw suction nozzle 41 is movably connected to the straw 4 or the quantitative air bag 3, and the stopper 5 is fixedly arranged inside the straw cover 6. The suction tube cover 6 can prevent saliva of people from splashing on the suction tube 41, and is more sanitary.

In another preferred embodiment, the quantitative air bag 3 is connected with an air outlet valve 7 which only allows air to flow from the inside of the quantitative air bag 3 to the outside atmosphere, for example, the air outlet valve 7 is arranged on the liquid inlet pipe 1 and close to the quantitative air bag 3, and the air outlet valve 7 only allows air to be discharged but not liquid to be discharged. After the air outlet valve 7 is arranged, the suction nozzle 41 is initially sealed by the plug 5, when the 4-head suction tube is used, people squeeze the quantitative air bag 3 by hands, air in the quantitative air bag 3 is discharged through the air outlet valve 7, so that negative pressure is generated in the quantitative air bag 3 to suck liquid medicine in the infusion bag 20 into the quantitative air bag 3, and after the use is finished, people cover the suction tube cover 6 and make the plug 5 seal the suction nozzle 41.

In another preferred embodiment, the quantitative air bag 3 is provided with a metering scale, thereby facilitating people to check the liquid medicine absorbed into the quantitative air bag 3 and ensuring the accuracy of medicine administration.

In another preferred embodiment, the straw 4 further comprises a connector 8 capable of being hermetically connected with the infusion bag 20 or the interface of the infusion bottle, and the connector 8 is sleeved outside the liquid inlet pipe 1 and is fixedly connected with the liquid inlet pipe 1. When the head of the suction tube 4 is connected with the infusion bag 20, the connector 8 is a rubber plug connected with the inner wall of the interface of the infusion bag 20; when the end of the suction pipe 4 is connected with an infusion bottle, the connector 8 is a rubber plug connected with the inner wall of the mouth of the infusion bottle or a cover connected with the outer wall of the mouth of the infusion bottle.
