Description

Consumable box and waste collection equipment

Technical Field

The utility model relates to the technical field of waste collection equipment, in particular to a consumable box and waste collection equipment.

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, neptene waste collection equipment from prior art siox production, see fig. 1. Fig. 1 is a schematic diagram of a prior art waste collection equipment, the waste collection equipment 1 comprising a mobile unit 11, a vacuum source 12, a consumable cartridge 14 and a waste collection tank 13. In this solution, the tubing 15, which is in contact with the surgical site, is connected to the waste collection canister 13 by means of a removable consumable cassette 14. The mobile unit 11 may allow for more flexibility in the location of the waste collection device 1 during use. By using the disposable consumable cartridge 14, the device can be sterilized without any more, and only the waste collection tank 13 can be cleaned and sterilized, so that the pollution risk of waste can be avoided to the greatest extent. Referring to fig. 1, in the prior art, when the consumable cartridge 14 is used, it needs to be inserted into a corresponding consumable cartridge insertion hole of the waste collection device 1, and this method may cause the consumable cartridge 14 to accidentally drop during use, thereby causing pollution to an operating room and also polluting the waste collection device. In order to prevent the consumable cartridge 14 from falling off, the prior art provides a fixing structure of the consumable cartridge, and an operator needs to rotate the consumable cartridge 14 so that it can be fixed in the socket of the waste collection device 1. Also, after use, the operator is required to manually rotate the take-out consumable cartridge 14. This structure also requires the operator to manually lock the consumable cartridge 14, and also requires the operator to rotate to take out the consumable cartridge 14 when taking out the consumable cartridge 14.

Based on the above prior art, consumable cartridges are known which require sampling during use. The Chinese invention with publication number CN104874035B discloses a consumable box, wherein the part of a suction interface connected with a hose is in ultrasonic welding with a shell of a filter basket, and sampling cannot be opened. Further, as disclosed in chinese patent application publication No. CN110115632a, a consumable cartridge is provided, after the hose connected to the consumable cartridge is removed, the connection base can be unscrewed, and the operation of sampling the tissue in the filter basket can be realized.

To sum up, in the consumable box in the prior art, a part of the consumable box can not realize tissue sampling in the surgical liquid, or the suction hose needs to be pulled out during sampling, besides the sampling operation is troublesome, the risk of excessive exposure of waste liquid can be caused.
