Abstract

The invention discloses a medical pumping device which comprises a shell, a gas pressurizing device and a medicine bag. According to the technical scheme, the gas pressurizing device is arranged to inject gas into the pressurizing bin arranged in the shell, the medicine bag is placed in the pressurizing bin, and after the medicine bag is squeezed by the gas blown out by the gas pressurizing device, medicine in the medicine bag is sprayed out through a medicine outlet nozzle. Blood pressure is resisted in a gas pressurization mode, the mode that liquid is pressed into blood vessels through atmospheric pressure and hydrostatic pressure in the prior art is replaced, the hydrostatic pressure does not need to be used for counteracting the blood pressure any more, hydraulic pressure difference does not need to be manufactured any more, and medicine does not need to be hung at a high position any more. The shell is arranged, the gas pressurizing device and the medicine bag are contained in the shell, and the shell can be carried by the patient and even fixed to the arm of the patient, so that space constraint of the infusion device to the patient during infusion is relieved, and the patient does not need to be infused at a fixed position any more.

Description

technical field [0001] The invention relates to the technical field of liquid pressurization devices, in particular to a medical pumping device. Background technique [0002] Intravenous infusion refers to the method of injecting a large amount of liquid, electrolyte or blood into the human body through the vein. Usually, intravenous infusion is to use the principle of atmospheric pressure and hydrostatic pressure to inject a large amount of sterile liquid, electrolyte, and medicine into the body through the vein. Chinese people often say drip. Most of the existing intravenous infusion methods are to pour the medicinal liquid into the medicine bottle or the medicine bag, and hang the medicine bottle or the medicine bag on a high place, and inject the medicine liquid into the inside of the blood vessel by utilizing the combined action of the atmospheric pressure and the hydrostatic pressure. In this infusion method, the medicinal liquid must be suspended at a high place to b...
