Abstract

The invention discloses a transfusion apparatus composed of a transfusion pump and a disposable transfusion device provided with a needle. The transfusion apparatus is characterized in that a pump door is arranged on the housing; a plate-shaped wrench is arranged on the outer side of the pump door; a first column is fixed to the wrench; the first column is provided with a jack; a pump door switch is arranged on the inner side of the pump door; one end of the pump door switch is provided with a hooked piece, and the other end of the pump door switch is inserted in the jack; a first spring is arranged between the pump door switch and the wrench; the housing is internally provided with a locking slot, and the hooked piece matches the locking slot; the housing is internally provided with a liquid stopping clip; a second spring is arranged between the liquid stopping clip and the housing; the liquid stopping clip is composed of a tail part, a body part and a head part; a step is fixedly formed at the portion, corresponding to the body part of the liquid stopping clip, of the housing; and a second column and a third column are arranged on the inner side of the pump door. The transfusion apparatus is simple is structure, is convenient to operate, and is higher in accuracy, safety and reliability for infusion.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an infusion device for intravenous injection. Background technique [0002] Intravenous infusion is a common way of administration in clinical treatment. According to the nature of the drug and the constitution of the patient, the speed of intravenous infusion is also different. At present, the common infusion set widely used clinically mainly relies on the pressure of the liquid level difference to infuse liquid into the recipient, and relies on the nursing staff to observe with the naked eye and manually adjust the wheel clamp to control the infusion speed. Ordinary infusion sets lack functions such as blockage alarm, bubble alarm, and control of drug infusion accuracy, which increases the burden of clinical care. The infusion pump is an instrument that can accurately control the number of infusion drops or the infusion flow rate to ensure that the drug can enter the patient's ...
