Feeding system for treating liquid medical waste

A feeding system for treating liquid medical waste, the feeding system comprising a receiving container for storing liquid medical waste and a feeding container for accommodating a coagulant;

• the feeding container comprises a feeding container body, guide slots provided at the circumferential outer side of the lower portion of the feeding container body, an outlet provided at the lower end of the feeding container body, and a seal which seals the outlet;
• the receiving container comprises a receiving container body, a top cover provided at the upper end of the receiving container body and covers said upper end, and a feeding connector connected with the top cover, and the feeding connector is provided with a feeding channel communicating with the receiving container body, wherein guide lugs are provided at the side wall of the feeding channel, and the guide lugs are configured for mating with the guide slots and extending into the guide slots, such that the feeding container is rotatably mounted to the feeding channel;
• characterized in that:
• the feeding connector is provided with a plurality of splitting portions for cutting through the seal, which are arranged along the circumference of the feeding channel and are spaced apart from each other by a certain distance;
• the guide slots comprise a first translational slot, a skewed slot and a second translational slot, wherein the first translational slot and the second translational slot are parallel to each other, and the first end of the skewed slot is connected with the first translational slot, the second end of the skewed slot is connected with the second translational slot;
• wherein when the guide lugs are moving along the first translational slot, the splitting portions are spaced apart from the seal;
• when the guide lugs are moving along the skewed slot from the first end to the second end of the skewed slot, the feeding container is guided to move downward such that the splitting portions come into contact with the seal and then pierce the seal;
• when the guide lugs are moving along the second translational slot, the splitting portions cut the seal along the circumferential direction of the feeding channel to destruct the seal, such that the coagulant accommodated in the feeding container is enabled to flow into the receiving container body through the outlet;
• wherein the number of the splitting portions is at least three, and wherein a pair of adjacent splitting portions are spaced from each other by a first circumferential angle, and the other pairs of adjacent splitting portions are spaced from each other by a second circumferential angle, and a circumferential angle corresponding to the second translational slot equals to a third circumferential angle;
• wherein the first circumferential angle is greater than the third circumferential angle and the third circumferential angle is greater than the second circumferential angle, such that when the guide lugs have moved through the entire second translational slot, a majority of the periphery of the seal has been cut by the splitting portions along the circumferential direction of the feeding channel;
• and
• wherein when the feeding container is mounted to the feeding channel, there is a radial gap between the circumferential edge of the outlet and the splitting portions, wherein the radial gap is no less than 0.5 mm and no more than 2.0 mm.
