Distributing device for infusion tube on infusion set

Abstract

The invention discloses a diversion device of an infusion tube on an infusion device. The diversion device comprises a diversion base, the diversion base includes an annular hub part, multiple spokesare arranged on the outer wall of the hub part, multiple ferrules are arranged at the outer ends of the spokes, and slots are formed in the inner ends of the hub part, spokes and ferrules respectively; a circular turntable is inserted in a slot of the diversion base, an arc groove is formed in the outer water of the turntable, a positioning column is inserted in the hub part of the diversion base,and a check ring is arranged on the outer wall of the lower end of the positioning column and abuts against the lower end face of the hub part of the diversion base; a vertical spline shaft arrangedon the upper end face of the positioning column penetrates through the turntable and is fixedly sleeved with a shaft sleeve, and the shaft sleeve abuts against the upper end face of the hub part of the diversion base. The structure is simple, and during infusion, a bottle stopper puncture device can be prevented from being pulled out of a suspended bag; switching can be achieved, and infusion is carried out through one suspended bag.

Description

Technical field: [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a diverting device for an infusion tube on 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...

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 cut-off and diversion device
