Portable vein infusion apparatus

Abstract

The invention discloses a portable vein infusion apparatus capable of realizing 24-hour working per day on the basis of air pressure application and mechanical quantitative infusion. According to the portable vein infusion apparatus, air pressure, a peristaltic pump and a mechanical clock technology are used; infusion powder is provided by compressed gas; an escapement regulator is linked with a gear speed change mechanism for limiting and regulating the rotating speed of a peristaltic motor to control the infusion speed; the work pulse of a peristaltic metering motor is weakened by a pulse damper for improving the infusion quality; the accidental blood loss in the infusion process is prevented by a one-way clutch. The portable vein infusion apparatus has the advantages that the structure is simple and stable; the work is reliable; the antijamming capability is high; the operation is convenient; the size is small; the weight is light; the concealing performance is high; the requirements of battlefield rescue, field curing, daily treatment middle and long-term storage, mobile infusion treatment and 24-hour working per day can be better met; meanwhile, the portable vein infusion apparatus is particularly suitable for special vein infusion treatment such as oxidation prevention and keeping in a dark place.

Description

technical field [0001] The invention relates to a portable venous infusion device, in particular to the technical field of a portable venous infusion device based on gas pressure and mechanical flow control for battlefield rescue, field rescue and daily treatment. Background technique [0002] At present, common venous infusion sets mainly include conventional venous infusion sets and electric venous infusion sets. Conventional venous infusion sets use potential energy as the power of infusion. The liquid must be placed at a certain height relative to the infused person. The potential energy of the liquid itself is converted into kinetic energy, which overcomes the venous pressure and the resistance of the infusion line and enters the human vein. Control the infusion speed and complete the intravenous infusion. The existing problems are: it needs a large working space, and it is difficult to infuse fluids while moving, which cannot meet the needs of field rescue and battlef...

AI Technical Summary

Problems solved by technology

The existing problems are: a large working space is required, and infusion is difficult during movement, which cannot meet the needs of field rescue and battlefield rescue.

The existing problems are: first, the peristaltic pump needs a large torque to work, and the weight and volume of the required motor, reducer and battery system are large, which is inconvenient to carry; second, it is very inconvenient to charge and replace the battery in the field or in the field, and the battery self-discharges The characteristics make it unsuitable for long-term combat readiness storage; the third is that the complex motor speed control system has low reliability; the fourth is that the motor control system is vulnerable to strong magnetic field and electric field interference, and is not suitable for modern warfare
