Problems solved by technology

[0004] However, the liquid outlet of the dripping funnel in the above-mentioned patent document is a through hole formed in the lower part of the dripping funnel, that is, the lower liquid port formed on the plane of the smooth transition of the lower part of the drip funnel, and the lower liquid port draws the soft rubber by suction. The base is adsorbed on the lower part of the dropping funnel, and the entire surface of the soft rubber base is in full contact with the lower liquid port and the bottom surface of the infusion set, with strong suction

Abstract

The invention discloses a drip device for transfusion and infusion sets. The drip device comprises a drip chamber, a connecting tube arranged between the drip chamber and a lower infusion tube, and a safety valve comprising a hard rubber part and a soft rubber base; the outer side wall of the soft rubber base is matched with the inner side wall of the hard rubber part to seal the open end of the hard rubber part; the axial length of the soft rubber base is smaller than that of the hard rubber part; a solution feeding channel is formed between the outer side wall of the hard rubber part and the inner side wall of the drip chamber; the length of a part of the connecting tube extending into the drip chamber is slightly greater than the distance from the closed end of the soft rubber base to the open end of the hard rubber part; and the closed end of the soft rubber base closes a tube orifice at the part of the connecting tube extending into the drip chamber. The invention solves a problem that a safety valve in a drip device for transfusion and infusion sets is adsorbed to the bottom of a drip chamber and hardly floats again in the prior art, and provides a drip device for transfusion and infusion sets, wherein the safety valve of the drip device easily floats again.

Description

technical field [0001] The invention relates to a medical device, in particular to a drip device for a blood transfusion set. Background technique [0002] The infusion set is mainly used to deliver medicinal liquid or blood to a patient, and its structure mainly includes an insertion needle, an upper infusion tube, a drip funnel, a lower infusion tube, a regulating switch and an injection needle. When the infusion device with the above structure is used to infuse a patient, medical personnel are required to check the infusion situation at any time, especially when infusion is given to some old people or children. The needle is pulled out. If the liquid has been exhausted, but the infusion needle is still in the human body, then due to the negative pressure in the infusion tube, the patient's blood will flow back to the infusion tube or air will enter the patient's body through the infusion set, thus causing injury or even death to the patient . [0003] In order to solve...
