Description

Drip cup

Technical Field

The utility model belongs to the technical field of medical and health equipment, concretely relates to drip cup.

Background

The infusion is one of the main measures of clinical treatment, and during the operation of intravenous infusion, a commonly used infusion tube is generally formed by connecting eight parts, namely an intravenous needle or an injection needle, a needle head protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip cup, a bottle plug puncture outfit, an air filter and the like. However, with the occurrence of some emergency situations, for example, when a patient is in a coma or sleepy state for transfusion, and medical staff and accompanying staff are not at the patient, when the liquid drops are over, the transfusion cannot be stopped in time, which may cause gas to enter the patient body and bring life risk to the patient; or when the pressure of the infusion tube is abnormal, a vein returns a large amount of blood through the infusion tube, and hemorrhagic shock can be caused in severe cases. The utility model provides a drip cup to solve the problem.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned phenomenon, the utility model provides a drip cup prevents that gas from getting into the internal possibility of patient along the transfer line when patient's infusion finishes, and the risk of a large amount of blood that return of vein when can preventing patient's infusion simultaneously has reduced the injury that emergency had taken for the patient when infusing.

A drip cup comprises a liquid inlet, an inlet kettle neck, an outlet kettle neck, a drip cup pipe body, a hollow floating block and a liquid outlet, wherein one end of the liquid inlet is connected with a liquid medicine bag, the other end of the liquid inlet is connected with the inlet kettle neck, the inlet kettle neck is connected with one end of the drip cup pipe body, the other end of the drip cup pipe body is connected with the outlet kettle neck, the outlet kettle neck is connected with a blood vessel of a patient through the liquid outlet, and the hollow floating block is arranged in the drip cup pipe body.
