Self-exhaust composite drip chamber assembly

Abstract

The invention discloses a self-exhaust composite drip chamber assembly which comprises an upper two-way device, a drip chamber and a lower two-way device. The lower two-way device is a composite lower two-way device comprising a composite lower two-way outer sheath and a composite lower two-way inner core. The composite lower two-way is attached to the outlet in the lower portion of the blow-molded drip chamber. A lower guide pipe connector on the composite lower two-way inner core is designed to be an inclined chamfer. The assembly depends on liquid surface tension and the adhesive force of the pipe wall of the lower two-way device, small bubbles are prevented from entering a lower guide pipe of an infusion set along with liquid medicine, safety hidden hazards caused by bubbles in the lower infusion guide pipe to patients are eliminated, medical disputes are reduced, labor intensity of nurses are greatly relieved, and work time and medical resources are saved.

Description

technical field [0001] The technology of the invention relates to the field of medical equipment, more specifically to a self-exhausting composite drip funnel assembly of a disposable infusion set. Background technique [0002] In the prior art, the patient hangs the medicine bottle on the infusion stand during infusion, and the nurse holds the cork puncturer of a common disposable infusion set and inserts it into the medicine bottle hanging upside down. The medicine liquid automatically flows into the infusion set tube by gravity, and the medicine When the liquid is dripped into the liquid dropper (Murphy's tube) of the ordinary disposable infusion set, due to the design defect of the ordinary disposable infusion set, a large number of fine air bubbles will be brought into the lower conduit (long tube) of the infusion set. Attached to the wall of the lower infusion tube, if these air bubbles are not discharged from the infusion tube, they may enter the patient's body along ...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the patient hangs the medicine bottle on the infusion stand during infusion, and the nurse holds the cork puncturer of a common disposable infusion set and inserts it into the medicine bottle hanging upside down. The medicine liquid automatically flows into the infusion set tube by gravity, and the medicine When the liquid is dripped into the liquid dropper (Murphy's tube) of the ordinary disposable infusion set, due to the design defect of the ordinary disposable infusion set, a large number of fine air bubbles will be brought into the lower conduit (long tube) of the infusion set. Attached to the wall of the lower infusion tube, if these air bubbles are not discharged from the infusion tube, they may enter the patient's body with the drug solution, causing vascular air embolism in the patient, causing life-threatening, or causing doctor-patient disputes

[0003] Therefore, whenever the nurse gives the patient the first infusion, it takes a lot of time to deal with the air bubbles in the wall of the infusion tube, and to discharge the downtube (long tube) of the infusion set upwards or downwards, which seriously affects the work efficiency of the medical staff.
