Exhaust-free infusion device

Abstract

The invention relates to an exhaust-free infusion device. The exhaust-free infusion device comprises a bottle stopper puncture device, a drop bucket with a dropper, a liquid medicine filter and an intravenous infusion needle which are serially connected by an infusion conduit, wherein a flow regulator is also arranged outside the infusion conduit between the drop bucket and the liquid medicine filter; a liquid guiding cover is arranged in the middle of the drop bucket; the liquid guiding cover is in interference fit with the inner wall of the drop bucket; the surface of the liquid guiding cover is provided with a liquid guiding groove which is downward extended; a liquid guiding column is arranged in the space formed by the liquid guiding cover and the lower part of the drop bucket; and the liquid guiding column is adhesively fixed with an outlet of the drop bucket and is communicated with a lower-part infusion conduit. A liquid medicine with the air cannot appear in the infusion conduit, so the 'bubble exhaust' operation of the infusion is saved. The exhaust-free infusion device has a reasonable structure, is convenient to operate and use, reduces the labor intensity of medical workers, saves nursing time, is time-saving and labor-saving, ensures that the infusion is safer, and is an ideal exhaust-free infusion device.

Description

technical field [0001] The invention belongs to the class of medical instruments, in particular to an exhaust-free infusion set. Background technique [0002] We know that disposable infusion sets are commonly used medical devices, which generally include bottle stopper piercers, drip funnels, liquid flow regulators, liquid medicine filters, and intravenous infusion needles, which are connected in series by infusion catheters. The medicinal liquid flows in through the cork puncturer, drips out from the dropper, flows into the infusion set through the outlet of the dropping funnel, and enters the human body through the medicinal liquid filter and the intravenous infusion needle. In the initial stage of infusion, since the inside of the catheter is empty, the liquid medicine can move down quickly when entering the catheter. Intermittent in the middle and sandwiched air. With the increase of the liquid medicine in the catheter, due to the effect of friction and surface tensio...

AI Technical Summary

Problems solved by technology

In this way, the medicinal liquid is wasted, the efficacy of the medicine is reduced, and the labor intensity of the medical staff is increased, which wastes a lot of working time.

However, the current infusion set and drip funnel do not have the function of avoiding exhaust at the initial stage of infusion.
