Cutoff deVice on infusion tube of infusion apparatus

Abstract

The inVention discloses a cutoff deVice on an infusion tube of an infusion apparatus. The cutoff deVice comprises a cuboid-shaped base, wherein a plurality of infusion tube through holes penetrating through the lower end face of the base are formed in the upper end face of the base, a grooVe channel communicated with the infusion tube through holes is formed in the front end face of the base, a front barrier strip is in inserted connection in the grooVe channel of the base, a grooVe opposite to the infusion tube through holes is formed in the back end face of the front barrier strip, a slidingblock is in inserted connection in the position, at the front side of the front barrier strip, of the grooVe channel of the base, a ' '-shaped front coVer is in inserted connection in the front end of the base, and the front coVer, the front barrier strip and the base are fixedly connected together through positioning pins; the sliding block abuts the end face of the inner side of the front coVer, a horizontal guiding grooVe is formed in the front end face of the front coVer, a stirring rod is formed on the sliding block, and the stirring rod is in inserted connection in the guiding grooVe ofthe front coVer and exposed to the front end face of the front coVer. The cutoff deVice on the infusion tube of the infusion apparatus has the adVantages that the structure is simple; when infusion is carried out, a bottle plug puncture deVice can be aVoided being pulled out of an infusion bag to achieVe switchoVer, so that infusion with single infusion bag is achieVed.

Description

Technical field: [0001] The invention relates to the technical field of medical instruments, in particular to a stopper on the infusion tube of an infusion set. Background technique: [0002] The infusion set is a common medical consumable. After aseptic treatment, a channel between the vein and the liquid medicine is established for intravenous infusion. Generally, it is composed of eight parts such as intravenous needle or injection needle, needle cap, infusion hose, liquid medicine filter, flow rate regulator, drip pot, bottle stopper piercer, and air filter. The current infusion set is generally equipped with only one cork piercer, and there are often multiple hanging bags during infusion. To replace the hanging bag, it is necessary to pull out the cork piercer from the empty hanging bag, and then insert it into a new hanging bag. However, the cork piercer is easily polluted during the pulling out process, so it is proposed whether multiple cork piercers can be equipped...

Problems solved by technology

The current infusion set is generally equipped with only one cork piercer, and there are often multiple hanging bags during infusion. To replace the hanging bag, it is necessary to pull out the cork piercer from the empty hanging bag, and then insert it into a new hanging bag. However, the cork piercer is easily polluted during the pull-out process, so it is proposed whether multiple cork piercers can be equipped with the corresponding hanging bags, so it is necessary to design a corresponding stopper
