Abstract

The invention discloses an infusion apparatus puncture joint. The infusion apparatus puncture joint comprises a base and a puncture head, and is characterized in that an air inlet channel and a liquidoutlet channel are formed in the puncture joint, wherein a one-way air inlet assembly is arranged on the air inlet channel, an air inlet of the air inlet channel is located in the base, and an air outlet of the air inlet channel is located in the puncture head; the liquid outlet channel comprises a liquid inlet section, a liquid storage cavity and a liquid outlet section; a liquid inlet of the liquid inlet section is located in the puncture head, and a liquid outlet of the liquid inlet section communicates with the liquid storage cavity; and a liquid inlet of the liquid outlet section communicates with the liquid storage cavity, and a liquid outlet of the liquid outlet section is located in the base. The infusion apparatus puncture joint has an air filtering function so as to remove air in liquid medicine entering a catheter, and meanwhile can be conveniently recycled, and the stability of inserting connection with a bottle cap of a medicine bottle is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, more specifically to a puncture joint of an infusion set. Background technique [0002] An infusion set is a device for delivering medicinal liquid to a patient. The structure of the current infusion set is generally composed of a venous needle, a protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip pot, a precision filter device, a bottle stopper puncturer, and an air intake pipe air filter. Under the action of atmospheric pressure during work, the liquid in the bottle flows into the drip funnel along the thinner infusion hose, and when the water column pressure of the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. [0003] In the prior art, the bottle stopper piercer of the infusion set does not have the function of air filtration, so that the medical solution entering the catheter of the infusi...
