Single-ball air pressurizer for use in rapid infusion

Abstract

The invention discloses a single-ball air pressurizer for use in rapid infusion. The single-ball air pressurizer consists of a pressure ball, a one-way air inlet valve and a one-way air outlet valve, wherein the pressure ball is made of rubber; the one-way air inlet valve and the one-way air outlet valve are arranged at the two ends of the pressure ball respectively; an air filter is further arranged at the inlet of the one-way air inlet valve; an air outlet joint is further arranged at the outlet of the one-way air outlet valve. By adopting the pressurizer, the air outlet joint can be inserted into an air inlet tube of an infusion set conveniently, and the inside of an infusion bottle is pressurized by operating the pressure ball. The pressurizer is simple in structure and low in price. When the inside of the infusion bottle is pressurized by using the pressurizer, the pressurizer can be operated conveniently, rapidly and efficiently, so that the workload of medical personnel is reduced greatly. The air filter is further arranged on the one-way air inlet valve, so that pollution of air on liquid medicaments is lowered at a certain degree.

Description

technical field [0001] The invention relates to a pressurizing device, in particular to a single-ball air pressurizer for rapid transfusion. Background technique [0002] In clinical practice, some patients need rapid and high-dose infusion according to the needs of treatment. However, due to the limitations of objective conditions such as the patient's blood vessels and injection needles, conventional infusion devices often fail to meet the requirements. To achieve the above goals, medical staff often use Use the needle tube to inject air into the infusion bottle to increase the pressure in the bottle and increase the infusion speed. Utilizing the needle tube to pressurize the infusion bottle, this method is likely to cause problems such as leakage, uneven drip speed, troublesome operation, and high labor intensity. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of single...
