Novel mechanical infusion and pressurization device and pressurization method

Abstract

The invention discloses a novel mechanical infusion and pressurization device and a pressurization method. The novel mechanical infusion and pressurization device comprises a bottom housing and an upper cover movably connected with the bottom housing, wherein a mechanical pressurization part is arranged in the bottom housing, a base plate is arranged above the mechanical pressurization part, the mechanical pressurization part comprises a base and a top seat which vertically arranged, the base consists of two base cross beams arranged side by side, and the top seat consists of two top seat cross beams arranged side by side. A fixed pin shaft and a movable pin shaft are arranged between the base cross beams, and a fixed pin shaft and a movable pin shaft are also arranged between the top base cross beams. A shear fork structure is arranged between the base and the top seat, one end of the shear fork structure is connected with the fixed pin shaft, the other end of the shear fork structure is connected with the movable pin shaft, and a spring is arranged between the fixed pin shaft and the movable pin shaft. The novel mechanical infusion and pressurization device contracts through the spring and drives the movable pin shaft connected with the spring to move, the shear fork structure upwards move immediately, the top seat cross beams perform upward jacking, an infusion bag is extruded by the base plate and housing, and liquid flows out.

Description

technical field

[0001] The invention relates to the research field of medical equipment, in particular to a novel mechanical infusion pressurizing device and a pressurizing method. Background technique

[0002] Various public health emergencies such as outdoor adventures, traffic accidents, natural disasters, and states of war often produce more or less trauma to the population, which in turn leads to hypovolemic shock in the wounded and sick. Shock is a syndrome manifested when the effective circulating blood volume in the human body is insufficient and the tissue is in a state of hypoperfusion. It can occur in many diseases, especially in severe trauma, and is one of the most common complications of severe trauma and an important cause of death. The common features of shock are: sudden onset and rapid development, generally severe trauma can lead to massive bleeding or a large amount of plasma extravasation into the interstitial space, a significant decrease in cardiac ou...
