Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.
As shown in fig. 1 and 2, the negative pressure flow diverter of the present embodiment comprises a negative pressure box 1 and a measuring bottle 3. The negative pressure box 1 is used for collecting and storing drainage liquid, and the metering bottle 3 is used for reading and recording the drainage value.
The negative pressure box 1 is composed of a top wall 11, a bottom wall 12 and a side wall 13 hermetically connected between the top wall 11 and the bottom wall 12, wherein the top wall 11 and the bottom wall 12 are both in a disc shape. The top wall 11, bottom wall 12 and side wall 13 form a sealed cavity 14. A spring 2 is arranged in the receptacle 14 of the vacuum cassette 1, the upper end of the spring 2 being supported on the top wall 11 and the lower end on the bottom wall 12. The side wall 13 is made of transparent material, so that the condition of accumulated liquid can be observed conveniently. The side wall 13 may be corrugated or non-corrugated, and may be in a contracted state under a certain external force, so that the negative pressure box 1 is in a negative pressure state.
A liquid inlet pipe 4 used for being connected with a stomach tube is arranged on the top wall 11 of the negative pressure box 1, and a liquid inlet valve 5 is arranged at the position of the liquid inlet pipe 4. The lower end of the side wall 13 of the negative pressure box 1 is provided with a liquid outlet pipe 6, and a liquid outlet valve 7 is arranged at the liquid outlet pipe 6. The arrangement of the liquid inlet valve 5 and the liquid outlet valve 7 is convenient for discharging accumulated liquid in the negative pressure box 1 without separating the negative pressure box 1 from the stomach tube.
