An infusion set exhaust device

Abstract

The invention discloses an exhaust device for an infusion set, comprising a drip hopper and an automatic exhaust valve. The automatic exhaust valve is installed at the inner bottom of the drip hopper, and there is no gap between the automatic exhaust valve and the bottom surface of the drip hopper, and the automatic exhaust valve is The valve includes a base and a plurality of exhaust catheters. The multiple exhaust catheters are evenly distributed on the base of the automatic exhaust valve. The multiple exhaust catheters and the liquid outlet at the upper end of the drip bucket are not on the same axis. Each exhaust catheter in the exhaust catheter is provided with 1 or 2 or 3 exhaust catheters, and the base of the automatic exhaust valve is provided with a hollow part and its lower part and the liquid outlet at the bottom of the drip hopper. The mouth is connected, the upper center of the hollow part of the base of the automatic exhaust valve is provided with a high platform, the invention can maximally remove the air that may enter the human body in the drip bucket, and improve the safety of infusion.

Description

technical field [0001] The invention belongs to the field of disposable medical instruments, in particular to an infusion set exhaust device in infusion sets. Background technique [0002] The infusion set currently used in clinical is generally mainly composed of a cork puncture device, a drip bucket, a hose, a flow regulator, and a joint. When the drug liquid is infused, it is necessary to turn the drip bucket upside down and squeeze the drip bucket to make the liquid flow from the bottom. When it rises up and reaches a certain height, put the drip bucket in order to discharge the air in the drip bucket. Improper operation, the liquid and gas in the drip hopper will be mixed into the hose, which will form bubbles and cause safety hazards. If the control is improper, it will cause the liquid level in the drip hopper to be too high or too low. According to the observation, the liquid level of the drip hopper is too low, which may cause the liquid and gas mixture to enter th...

Problems solved by technology

In this patent, due to the large space in the inner part of the base, it is easy to form air bubbles in the inner part of the base during the first exhaust, which may cause hidden dangers of entering the human body.

The principle is that the liquid flows out from the liquid inlet on the upper part of the dripping funnel of the infusion set, flows through the automatic exhaust valve, enters the inner part of the base through the exhaust, the exhaust on the catheter tube, and the liquid guiding groove, and finally flows to the outlet at the lower end of the dripping funnel. The liquid port enters the human body. Since the space inside the base is relatively large, when the liquid flows downward, the liquid flowing out from the exhaust and liquid guide grooves will flow to each method. , and then flow to the liquid outlet first, and part of the cavity inside the base is not filled, resulting in the accumulation of air bubbles
