Description

Infusion apparatus capable of adjusting dropping number

Technical Field

The utility model relates to the technical field of infusion apparatus, in particular to an infusion apparatus capable of adjusting the number of drops.

Background

Infusion is one of the basic methods currently used to treat disease. In the process of carrying out infusion treatment on patients by using an infusion apparatus in hospitals, the proper intravenous drip speed needs to be selected according to medicines and the illness states of the patients. At present, in each large hospital ward, nursing work for the transfusion condition of a patient is an essential part for daily work of nurses. The infusion apparatus is also called an infusion pump, and is a medical apparatus for infusion as the name suggests. The traditional infusion method is that liquid in a bottle or an infusion bag is suspended at a high position, the liquid flows into a vein through an infusion leather tube by utilizing the action of gravity, the flow rate is manually adjusted by a clamp arranged on the leather tube, and the adjustment index is the dropping speed in a dropper. Infusion is a highly specialized medical technique for delivering a large amount of sterile liquid, dielectric medium and medicine into the body from blood vessels, and is also the most common treatment method in clinic. The number of infusion drops (i.e., the speed at which they are usually administered) is adjusted according to the type of fluid, the type of disease, the age and physical condition of the patient. The existing transfusion regulator is generally assembled with a disposable transfusion device into a whole and cannot be reused, the structure of the transfusion regulator is that a wedge-shaped groove is formed in a fixing seat, a transfusion tube penetrates through the wedge-shaped groove, a rotary regulating wheel is arranged in the groove, the transfusion tube is pushed and contracted or retreated to loosen the transfusion tube before the regulating wheel, approximate flow is regulated, and if accurate dropping number is to be obtained, a transfusion nurse is required to regulate the transfusion regulator through counting of a stopwatch.

At present, because the adjusting distance between wedge-shaped groove and the rotation regulating wheel of current infusion regulator is shorter, the swiveling wheel is great with transfer line area of contact, and the accurate infusion of adjusting is very difficult, need adjust many times repeatedly sometimes and can obtain satisfied infusion speed to patient has lost the infusion in order to can soon a little when carrying out the infusion, often can not consider that doctor's advice holds in the palm privately and adjusts the infusion regulator, is unfavorable for patient's recovery very much.
