[0021] Specific implementation mode three: combination figure 1 with Figure 7 To explain this embodiment, this embodiment also includes a pressure indicator 10, which is arranged in the tank body 1-1. The pressure indicator 10 is composed of a transparent tube 10-1 and a piston 10-2, and the piston 10-2 is arranged in the transparent tube. In 10-1, a scale is provided on the outer surface of the transparent tube 10-1. The tank body 1-1 can be made of plastic. The pressure indicator 10 is fixed in the tank body 1-1. After the tank body 1-1 is inflated, the pressure inside the tank body 1-1 increases, causing the piston 10-2 to move inward. Push forward, otherwise exit outward. The scale on the front of the piston is the pressure value in the tank. Others are the same as the first or second embodiment.

Abstract

The invention discloses a pneumatic device for intravenous infusion, relates to a pneumatic device and aims to solve the problems that the conventional intravenous infusion needs an infusion bottle bracket for hanging an infusion bottle, which is inconvenient for a patient who needs to move. A spring and a plug are arranged inside a spring seat; an opening baffle sheet is fixed at the outermost end of the spring seat; and a sealing gasket is fixed on the inner side of the opening baffle sheet and is matched with the plug. A cylinder is fixed on a base; an overhead valve is fixed on the base inside the cylinder; a plastic gasket base is fixed on an outer wall of the overhead valve; a plastic gasket is arranged on the plastic gasket base; one end of an air outlet adapter is communicated with the overhead valve; internal threads are formed on an inner wall of the cylinder; and the internal threads of the cylinder are matched with external threads of a tank body. The pneumatic device has the inflation pressure of 0.6 to 1 MPa and the inflation capacity of 500 to 600 cubic centimeters, can be used for 2,000ml of liquid medicine for intravenous infusion, and has the advantages of convenient carrying, high safety, easy disinfection and convenient replacement.

Description

Technical field [0001] The invention relates to a pneumatic device. Background technique [0002] The current intravenous drip requires a hanging bottle holder to hang the infusion bottle. Some modern hospitals have pre-installed a suspension for hanging the infusion bottle on the ceiling of the ward. Patients often have to sit on a bed or chair during infusion. on. It is very inconvenient for patients who need to move. It is convenient and convenient to go to the bathroom, eat in the dining room, take a walk in the hospital, etc. You can often see someone holding a bottle to accompany the patient in and out. For severe patients, patients who need to replenish a large amount of liquid medicine in time, in order to ensure the pressure of the infusion, it is often necessary to raise the infusion bottle on the hanging bottle holder to obtain a faster infusion rate. In recent years, someone invented a pressurized infusion device to replace the bottle holder, but due to many problem...
