Description

Improved negative pressure suction bottle

technical field

The utility model belongs to the technical field of medical aids, in particular to an improved negative pressure suction bottle.

Background technique

Negative pressure suction bottle is used to suck the contents of bleeding, exudate, pus, and chest viscera during the operation, so as to make the operation clear and reduce the chance of contamination. The principle of the suction bottle is very simple, that is, through the suction on the top of the suction bottle The head forms a negative pressure state inside the bottle body, so that the atmospheric pressure will squeeze the material outside the suction head to the suction head, thereby completing the "attraction" effect.

In clinical practice, the volume of the negative pressure suction bottle cannot be made large. When the drainage fluid is full, the doctor needs to remove the negative pressure fluid collection bottle, pour out the drainage fluid or replace a new drainage bottle, so the drainage process will be interrupted. Interruption is not only time-consuming and labor-intensive, but also may cause physical discomfort to the patient. If the suction bottle is full during the operation, the doctor will stop the operation to dump the sewage, and wait for the suction bottle after the operation is finished. The surgical operation can only be continued after the negative pressure is re-established; for the patient, this will undoubtedly lead to a delay in the operation time, an increase in the risk of the operation, and further increase the cost of the operation. Moreover, in the initial suction stage of the existing drainage bottle, there will be secretions with larger particles entering the drainage bottle along with the drainage fluid at the drainage end after the operation, which will easily cause blockage of the drainage tube and affect the suction effect.

In summary, there is an urgent need to design an improved negative pressure suction bottle that overcomes the above-mentioned problems.
