Flow-adjustable mechanical automatic infusion instrument

Abstract

The invention discloses a flow-adjustable mechanical automatic infusion instrument which comprises an infusion bag (1), an infusion tube (2) and an infusion needle (3). The infusion bag (1) is arranged in a sealed air pressure bag (4), the infusion tube (2) connected with the infusion bag (1) penetrates out of the air pressure bag (4) and then is connected with the infusion needle (3), the air pressure bag (4) is communicated with an airbag (5), and a mechanical speed adjusting device (6) is arranged on the infusion tube (2). The flow-adjustable mechanical automatic infusion instrument has the advantages that the flow-adjustable mechanical automatic infusion instrument is convenient to use and practical, reliable in work and free of power consumption, the air pressure bag and the mechanical speed regulating device can be reused, cost is low, infusion speed is adjustable, and the control precision is high.

Description

technical field [0001] The invention relates to an infusion system, in particular to a flow-adjustable mechanical automatic infusion instrument. Background technique [0002] Infusion is a method commonly used clinically to replenish body fluids or infuse drugs. There are mainly three ways of infusion: vein, artery and intraosseous. [0003] The traditional infusion bottle is hung on the infusion stand or other hooks, and then the infusion needle is inserted into the patient's body for infusion. In order to maintain the pressure of the infusion during the infusion, the height of the infusion bottle must always be higher than the infusion needle. There are following deficiencies in this method: [0004] First: When the hanging height of the infusion bag is not enough or the amount of liquid in the infusion bag becomes less, blood backflow is likely to occur due to insufficient pressure difference. If the blood backover time is not found in time and blood clots will form in t...

AI Technical Summary

Problems solved by technology

[0004] First: When the hanging height of the infusion bag is not enough or the amount of liquid in the infusion bag becomes less, blood backflow is likely to occur due to insufficient pressure difference. If the blood backover time is not found in time and blood clots will form in the infusion tube, it is necessary to replace the infusion tube and re-insert the needle Infusion, the harm to the patient is great;

[0005] Second, when the infusion speed needs to be accelerated due to rescuing critically ill patients, the pressure can only be manually increased to adjust the infusion speed, which is inconvenient to operate, time-consuming and laborious;

[0006] The third infusion requires the patient's position to be relatively fixed in order to maintain a relatively stable fluid input rate. If the patient needs to move, the appropriate height of the infusion bag must be maintained, which also brings a lot of inconvenience; Hold the infusion bottle high to maintain the pressure difference required for the infusion, which is extremely inconvenient and has poor reliability

[0007] Fourth, especially in wartime or when encountering emergencies, there will be a large number of wounded and sick who need infusion or transfer while infusion. Due to environmental constraints, it is very inconvenient to hang the infusion bag, and it is impossible to equip so many nurses. Unable to meet medical needs
