Background

In the practice of certain surgical procedures, liquid, semi-solid and solid waste of the type including, in particular, body fluids such as blood, and infusion solutions introduced to the surgical site during the procedure, are inevitably produced, and in addition, solid and semi-solid waste produced during the procedure includes fragments of tissue and small pieces of surgical material that may remain in the body site. Ideally, the waste, once generated, is collected so as not to contaminate the surgical site, nor be a biohazard to the operating room or other site where the surgical procedure is performed.

In the prior art, there are a variety of waste collection systems available for medical personnel to collect waste generated during surgery or after surgery has been performed. The principle is mainly that the waste generated at the operation site is sucked into a specific collecting container by a suction force generated by a vacuum source. That is, after the system is activated, the suction force generated by the vacuum source reaches the surgical site, drawing waste into a specific collection container through the tubing that the surgical site contacts.

For example, the neptrene medical waste collection facility of prior art, the history of which is available in the prior art, see fig. 1. Fig. 1 is a schematic structural diagram of a medical waste collection facility of prior art, the medical waste collection facility 1 comprising a mobile unit 11, a vacuum source 12, a consumable cassette 14 and a waste collection tank 13.
