Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a suction device with anti-aspiration function. Background Technology

[0002] A suction device is used to remove bleeding, exudate, pus, and contents from thoracic organs during surgery, making the surgical procedure clearer and reducing the chance of contamination. The principle of a suction device is very simple: by creating a negative pressure state at its suction head, atmospheric pressure forces the material outside the suction head towards it, thus achieving the "suction" effect.

[0003] Whether it's clearing accumulated blood or fluid during surgery, holding the severed ends of ruptured blood vessels, suctioning sputum in emergency situations, or performing gynecological abortions, suction devices are indispensable. Over the years, many different types of suction devices have emerged. Based on their power source, they can generally be divided into: independent electric suction devices and centrally controlled suction devices.

[0004] When medical staff perform surgery on patients, they use a suction head to aspirate the bleeding and pus generated during the operation into a fluid collection bottle. Currently, existing suction devices do not have an anti-aspiration function. When the liquid level in the collection bottle is higher than the negative pressure suction port of the negative pressure tube, the liquid collected in the collection bottle is very likely to be accidentally aspirated into the negative pressure equipment used to create a negative pressure environment for negative pressure suction, which can easily damage the negative pressure equipment and cause great inconvenience to medical staff in their negative pressure suction work during surgery.
