This utility model discloses an anti-clogging pipeline for a venous chamber in a blood purification tubing system. The anti-clogging pipeline includes a filter bag, an inlet pipe, and an outlet pipe. The inlet pipe is connected to the inlet end of the filter bag, and the outlet pipe is connected to the outlet end of the filter bag. A filter screen is provided at the outlet end of the filter bag or at the port of the outlet pipe near the filter bag. When the venous chamber is clogged, the anti-clogging pipeline is connected in parallel with the venous chamber to avoid interruption or termination of treatment, allowing treatment to continue. This also helps to save medical equipment and reduce treatment costs.

This invention relates to the field of queue management technology for Ethernet switching chips, specifically to a method for managing the probabilistic random drop of packets in a queue, applied to multi-service queue management in Ethernet switching chips. The method configures drop thresholds, sampling periods, prediction step sizes, congestion change rate thresholds, and target drop ratios for each service queue; calculates the congestion change rate and predicted queue length based on the real-time average queue length and its historical sequence, and determines the direction of threshold adjustment accordingly; determines the adjustment step value based on the deviation between the actual drop ratio and the target drop ratio, and updates the minimum and maximum drop thresholds. When packets are enqueued, a pseudo-random number is generated using a linear feedback shift register, and combined with the congestion change rate to generate a dynamic comparison threshold to complete the random drop judgment. This invention can improve queue congestion response speed and reduce hardware storage resource consumption.

The utility model discloses a hand and foot universal warmer paste which comprises a warmer paste body and a finger leaking seam, and the finger leaking seam is formed in the side portion of the warmer paste body. The heat generation device convenient replacement assembly comprises a material storage groove and a heat generation device body, the material storage groove is formed in the warmer pad body, the heat generation device body is movably installed in the material storage groove, and the heat generation device convenient replacement assembly further comprises a limiting silica gel strip. And a limiting silica gel strip is movably inserted into the material storage groove in the warmer pad main body in a penetrating manner. According to the heat generating device, the heat generating device body can be quickly mounted and dismounted in the storage tank, so that the heat generating device body can be conveniently replaced after losing efficacy, the whole warmer pad is prevented from being discarded, the pollution to the environment is reduced, and meanwhile, the production cost is saved.
