Technical Field

The invention relates to the technical field of medical instruments, in particular to a negative pressure suction device for surgical nursing in obstetrics and gynecology department.

Background

The aspirator is used for aspirating and removing the contents of hemorrhage, exudate, pus and thoracic organs in the operation, so that the operation is clear, and the pollution chance is reduced. The principle of the suction apparatus is very simple, namely, the negative pressure state of the suction head is manufactured by a certain method, so that substances outside the suction head can be extruded to the suction head by atmospheric pressure, and the suction effect is achieved. The suction apparatus can not be used for clearing accumulated blood or accumulated liquid, holding the broken end of a ruptured blood vessel, sucking phlegm in clinical emergency, induced abortion in gynecological operation and the like in surgical operation. The suction apparatus can be divided into the following parts according to the difference of power sources: an independent electric suction apparatus and a centralized control suction apparatus.

At present, there are some defects in current gynaecology with operation nursing negative pressure suction apparatus in the use, for example, current gynaecology is with operation nursing negative pressure suction apparatus generally relies on the vacuum pump to provide the suction power source, directly relies on the electric energy promptly, just can not continue to use the suction apparatus when emergency power failure, the life safety that leads to patient easily receives certain threat, and has also increased medical personnel's the degree of difficulty of performing the operation, when emergency power failure, the suction apparatus negative pressure disappears simultaneously, the inside liquid of suction tube flows back easily.
