Non-suspension closed infusion bottle

Abstract

The invention relates to a non-suspension closed infusion bottle. The non-suspension closed infusion bottle comprises a cuboid bottle body, two parallel and symmetric piston pieces are installed in the bottle body, the two piston pieces and a pair of inner side walls of the bottle body are identical in size and parallel, the bottle body is divided into three parallel sealed spaces through the two piston pieces, the sealed spaces on the two sides are liquid storage cavities, and the sealed space in the middle is a pressure cavity. In the pressure cavity, a compressed spring is installed between the two piston pieces. A control valve communicated with outside air is arranged at the top end of the pressure cavity. Liquid outlet ends are formed at the bottom ends of the liquid storage cavities, an infusion pipe is installed at the liquid outlet ends, and a speed regulator is further arranged on the infusion pipe. By means of the infusion bottle, infusion can be achieved without the need of suspension, liquid in the bottle is kept clean in the infusion process, and air pollution is effectively prevented.

Description

technical field [0001] The invention relates to a medical product, in particular to an infusion bottle. Background technique [0002] At present, the commonly used infusion bottle is a hanging infusion bottle. During use, the infusion bottle is placed at a high place, and the liquid enters the blood vessel through the action of gravity. Enter the infusion bottle to balance the air pressure in the bottle; this kind of infusion bottle has the following defects: first, each infusion needs to be suspended at a high place, which is troublesome for medical staff to operate and has a large safety hazard; When there are too many people, the hanging position of the infusion bottle is tense, which affects the efficiency of hospital infusion and treatment; thirdly, the infusion bottle is suspended at a high place, which restricts the normal activities of the patient and makes it inconvenient to perform other activities during the infusion; if the infusion time is too long and needs t...
