Pre-flushing device of hemoperfusion device

Abstract

The invention discloses a pre-flushing device of a hemoperfusion device, and belongs to the technical field of medical instruments. Thepre-flushing devicecomprises a puncture component, a connecting component and a collecting component, wherein the puncture component is used for puncturing a flushing bag to enable a flushing fluid to flow out along an internal channel, a nut is arranged at one end of the puncture component, a threaded head is arranged at each of the two ends of the connecting component, the collecting component is at least provided with one threaded head, the threaded heads are matched with the nut, one end of the connecting component is communicated with the puncture component through a threaded head, the other end of the connecting component is communicated with the input end of a hemoperfusion device through a threaded head, and the collecting component is communicated with the output end of the hemoperfusion device through a threaded head. According to the pre-flushing device, the nut and the spiral head which are matched with each other are arranged between the puncture component and the connecting component, so that the whole pre-flushing device is good in leakproofness; and the input end and the output end of the hemoperfusion device do not make contact with the external environment while the connecting component does not need to be detached and discarded when pre-flushing is completed, so that operation steps are simplified, and the infection risk is greatly reduced.

Description

technical field [0001] The application relates to a pre-flushing device for a hemoperfusion device, which belongs to the technical field of medical instruments. Background technique [0002] Blood purification technology is more and more widely used in clinical practice, expanding from the traditional simple renal replacement therapy to the removal of inflammatory mediators, liver function replacement and other fields. The treatment method has developed from a single hemofiltration and perfusion to a combined blood purification method, including: hemofiltration combined with perfusion, plasma separation combined with hemoperfusion bilirubin adsorption, etc. [0003] Blood purification treatment requires strict aseptic operation due to direct contact with blood. At present, infusion sets are generally used for pre-flushing, and ordinary infusion tubes are used to insert into the input and output ends of the hemoperfusion device. There will be gaps at the connection of the inf...

Problems solved by technology

[0003] Blood purification treatment requires strict aseptic operation due to direct contact with blood. At present, infusion sets are generally used for pre-flushing, and ordinary infusion tubes are used to insert into the input and output ends of the hemoperfusion device. There will be gaps at the connection of the infusion tubes, which increases the risk of infection. And when the pre-flushing is completed, the entire infusion tube needs to be pulled out and discarded, and replaced with a tube that matches the instrument. When the infusion tube is pulled out for replacement, the connections will be exposed to the external environment again, and the risk of infection is greatly increased. The whole preflushing process requires the nurse to hold the hemoperfusion device, which increases the manpower consumption of the nurse
