Abstract

The invention relates to an arterial blood gas collection device for preventing iatrogenic injury, which comprises a sleeve, an inner cylinder, a needle cylinder piston, a piston push rod, a needle head, a sealing device and a needle sleeve, the needle head comprises a first tip and a second tip, and a needle head lug boss is arranged on the outer peripheral surface of the side wall of the needle head; a first spring is arranged between the end face of the inner cylinder and the second fixing support. A second spring is arranged between the needle sleeve and the second fixing bracket; the needle cylinder piston is arranged in the inner cylinder; the inner cylinder is arranged in the sleeve; the needle cylinder piston is made of a material capable of permeating air, the material of the needle cylinder piston is self-sealing porous polyethylene, and partially saponified polyvinyl alcohol, polyacrylate, acrylic acid-vinyl ester, polyethylene oxide and / or cellulose polymer are mixed in the self-sealing porous polyethylene; the porosity of the self-sealing porous polyethylene ranges from 15% to 40%; the average pore size ranges from 5 [mu] m to 20 [mu] m.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an arterial blood gas collection device for preventing iatrogenic injury. Background technique [0002] Blood gas analysis has very important clinical significance for patients with respiratory diseases. Arterial blood gas shows the two physiological functions of respiration and metabolism, and the composition of arterial blood is consistent throughout the body, and arterial blood is necessary to correctly evaluate blood oxygen content. Normal blood gas and acid-base balance is an important aspect of the stable internal environment of body fluids, which the body depends on for healthy survival. Blood gas analysis can directly reflect the pulmonary ventilation function and its accompanying acid-base balance regulation state. Blood gas analysis provides a reliable basis for the diagnosis and treatment of respiratory failure, monitoring for acid-base imbalance, hypoxia and ...
