Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the invention only in a schematic way, and thus show only the components that are relevant to the invention, and the directions and references (e.g., upper, lower, left, right, etc.) may be used only to help describe the features in the drawings. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the claimed subject matter is defined only by the appended claims and equivalents thereof.
Example 1
As shown in fig. 1-5, a washable disposable negative pressure drainage device comprises a negative pressure ball 1, a pipette 2 and a cleaning tube 3, wherein a one-way valve 4 is fixed at the front end of the negative pressure ball 1, an outlet of the one-way valve 4 is communicated with the inside of the negative pressure ball 1, an inlet of the one-way valve 4 is communicated with the pipette 2, a liquid discharge port 101 is formed at the rear end of the negative pressure ball 1, a first plug 9 is plugged in the liquid discharge port 101, the cleaning tube 3 is sleeved outside the pipette 2, a cleaning channel 5 is formed between the inner peripheral wall of the cleaning tube 3 and the outer peripheral wall of the pipette 2, the rear end of the cleaning tube 3 is fixed on the pipette 2 and seals the rear end of the cleaning channel 5, and a liquid inlet 301 communicated with the cleaning channel 5 is formed on the outer peripheral wall of the rear end of the cleaning tube 3.
The cleaning device further comprises a cleaning bag 6, the cleaning bag 6 is communicated with the liquid inlet 301 through a pipeline 7, and a switch valve 8 is arranged on the pipeline 7; when the ooff valve 8 is closed, through the setting of wasing bag 6, can be in advance with wasing the liquid medicine storage in wasing bag 6, when needs wash the wound, open ooff valve 8, then can suitably manual extrusion wash bag 6, make the washing liquid medicine get into and wash passageway 5, increase the velocity of flow of wasing the liquid medicine, improve the cleaning performance to the wound.
