Embodiment Construction

[0014] First of all, the infusion tube used in this device has only a single hole at the end inserted into the infusion bottle 2 for the output of medicinal liquid, without the additional air inlet design used in traditional hanging infusion; the bottom of the infusion bottle 2 is connected with a glass tube 10 . When leaving the factory, after the physiological saline is packed in the infusion bottle 2, a stopper can be used to plug the glass tube 10 mouthfuls to prevent the liquid from flowing out.

[0015] The device consists of a compressed air bottle 1 and an ordinary infusion bottle 2. Compressed air bottle 1 bottleneck design has an air inlet 7 and an air outlet 8. The air compressor injects air into the compressed air bottle 1 through the air inlet 7, so that the compressed air bottle 1 is filled with compressed air.

[0016] Unplug the stopper of the glass tube 10 at the bottom of the infusion bottle 2, and connect the air outlet 8 of the compressed air bottle 1 with...

Abstract

An air-compressing transfusion device relates to a method to realize a transfusion course by compressing an air bottle to provide a transfusion bottle with an invariable air pressure to press a medical liquid in the transfusion bottle into a blood vessel. The transfusion device is applied to a field hospital and the circumstances that due to a limited condition, the transfusion bottle could not be hung highly or a wounded person need carrying by an improvised stretcher. The device does not need a power supply and is a mechanical structure of a pure pressure principle. Nowadays the compressed air is frequently used, and the method and the device can be performed very conveniently. A plurality of disadvantages during the traditional transfusion course is effectively solved.

Description

technical field [0001] The invention relates to a medical transfusion device, especially the method of pressing the medicinal liquid in the transfusion bottle into the blood vessel by providing a constant pressure to the transfusion bottle through a compressed air bottle to realize the transfusion process, which is suitable for field hospitals or transporting the wounded on a simple stretcher During the process, the infusion bag cannot be hung high due to limited conditions. Background technique [0002] At present, when infusion is generally performed in the hospital, the infusion bottle or the infusion bag is hung on the infusion stand, so that the gravity of the medicinal liquid itself and the effect of atmospheric pressure can be used to make the medicinal liquid flow into the blood vessel smoothly. However, in some special occasions, the basic medical conditions and facilities are difficult to meet, such as the field hospital next to the battlefield, the stretcher that ...
