Self-adaptive portable constant pressure infusion apparatus

Abstract

The invention discloses a self-adaptive portable constant pressure infusion apparatus which comprises a working air bag (8), a controlling system (6) and a flow velocity adjusting mechanism. An air inlet pipe is arranged on the working air bag (8) and is provided with a pressure sensor (3) and an air discharging valve (4). The controlling system (6) is electrically connected with the pressure sensor (3) and the air discharging valve (4) respectively. The flow velocity adjusting mechanism comprises a flow velocity sensor (5) and a flow adjusting valve, and the flow velocity sensor (5) and the flow adjusting valve are controlled by the controlling system (6). The working air bag (8) and an infusion bag are both placed in a cavity (7) with a fixed size, and the flow velocity sensor (5) and the flow adjusting valve are both arranged on an infusion tube of the infusion bag. The self-adaptive portable constant pressure infusion apparatus can achieve real-time monitoring of the infusion process, safely and effectively finish the infusion process, is low in manufacturing and using cost, and is suitable for being adopted widely.

Description

technical field [0001] The invention relates to an infusion set, in particular to an adaptive portable constant pressure infusion set. Background technique [0002] At present, gravity infusion is mainly used for infusion, that is, the position of the infusion bag must be at a certain height from the needle, and the liquid is pressed into the human body by atmospheric pressure and liquid column pressure. Its main shortcoming and deficiency are: when first aid, rescue or hospital are busy, special person or support frame is needed to place the infusion bag at a certain height, which is not only limited by space but also wastes manpower and material resources, which is very inconvenient. [0003] In order to solve the problem of space limitation and waste of manpower, the existing improved technology starts from the principle of infusion, hoping to realize the infusion and blood transfusion of the wounded and sick in any environment, no need to be equipped with corresponding m...

Problems solved by technology

Its main disadvantages and shortcomings are: in emergency, rescue or when the hospital is busy, a special person or a support frame is required to place the infusion bag at a certain height, which is not only limited by space but also wastes manpower and material resources, which is very inconvenient

[0003] In order to solve the problem of space limitation and manpower waste, the existing improved technology starts from the principle of infusion, and expects to realize the infusion and blood transfusion of the wounded and sick in any environment without the need for corresponding manpower or brackets, but the problem of the existing technology is that the mechanism is too complicated, The cost is high, and there is no flow rate monitoring device in the system, and the process stability is poor
