Description

Butt joint equipment

Technical Field

The utility model relates to a docking device for docking with a waste collection device for collecting and treating waste materials generated in a medical process in a waste collection and treatment system.

Background

In the implementation of a particular surgical procedure, liquid, semi-solid and solid waste of the type that inevitably includes body fluids, such as blood, and perfusion solutions introduced to the surgical site during the procedure, and solid and semi-solid waste generated during the procedure includes tissue fragments and small pieces of surgical material that may remain in the body site. Ideally, the waste material, once generated, is collected so that it does not contaminate the surgical site or become 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 and disposal systems available for medical personnel to collect waste generated during a procedure after the procedure has been performed or after the procedure has been performed. The principle is mainly that the waste generated at the operation site is sucked into a specific collection container by the 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, thereby drawing waste through the tubing that the surgical site contacts into a specific collection container.

In medical waste collection and treatment systems, waste material is collected in a waste collection container connected to a vacuum source, which is typically mounted on a wheeled portable trolley for easy transport. Generally, during the pumping process, when the storage volume of the waste collection container reaches a predetermined volume, it is necessary to empty the waste collection container, and earlier prior art methods pushed the waste collection device to a docking station and emptied and cleaned. The waste collection unit, when docked to the docking station, begins to empty and once empty the waste collection container is cleaned by the cleaning system by sterilisation and cleaning. In a series of medical procedures, each procedure requires emptying, and the frequent operation of pushing the waste collection device to the docking station each time causes inconvenience to the user and affects the medical schedule. Therefore, in response to this technical drawback, a transfer device has been developed specifically for transporting waste of a waste collection device to a docking station, i.e. a docking device for specifically transporting waste in a waste collection device, which device typically comprises two connectors for docking with two connectors of a waste collection device to form a fluid path communication, one for transferring waste of the waste collection device to the docking device and the other for cleaning a waste collection container of the waste collection device.

Since the joints in the prior art can only move in the directions up, down, front, back, left and right at most, the correct directions can only be four directions, up, down, left and right, and the joints of the docking equipment can only be inserted by moving back and forth after being aligned up, down, left and right. In the prior art, a structure for realizing six-direction movement of a butt joint device end to a joint needs a support capable of moving in four directions, the support needs a plurality of elastic parts and a plurality of structural parts to be changed, in addition, a stepping motor realizes the movement in the other two directions, the structure is complex, the equipment cost is high, the insertion of the joint can be realized only after the butt joint device and the waste collection device are aligned very accurately, namely, the butt joint of the butt joint device and the waste collection device needs to be aligned before being contacted, the operation of matching a plug with a socket can be carried out, the alignment can not be continued after the plug is contacted with the socket, the structure not only is complex in alignment operation, but also the complexity and the cost of the equipment are increased.
