Abstract
The invention discloses a tracheal intubation unit with a fed medicine check device. The tracheal intubation unit comprises a tracheal catheter, an inflating catheter, a medicine feeding catheter, a connection port, a body entering port and the fed medicine check device, wherein the fed medicine check device comprises a fed medicine check valve joint, a check tube and a check elastic head; the inner diameter of the check tube is larger than the diameter of the medicine feeding catheter, the check elastic head comprises a base, and the diameter of the base is equal to the maximum diameter of the check elastic head, smaller than the diameter of the check tube and larger than the diameter of a round hole in a raised strip. The physical principle of the tracheal intubation unit with the fed medicine check device is that under propulsion of pressure of a water column of a syringe, liquid medicine in the syringe flows into the tracheal catheter through the fed medicine check device. After medicine injection, the check elastic head moves to the raised strip under the action of gravitative pressure of a liquid, the base of the check elastic head is tightly connected with the raised strip, and a sealing structure is formed to intercept liquid backflow.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a straight tracheal intubation tube. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called endotracheal intubation. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. . [0003] In actual use, the tracheal intubation includes a drug dosing catheter and an inflatable catheter, and the dosing catheter is used to add drugs for the convenience of treatment after successful intubation. However, during the process of adding the drug, the drug is pushed to be added due to the effect of pressure. After the liquid is added, the liquid is easily refluxed due to the strong internal pressure, resulting in the failure of the drug addition, affecting the results of the dru...
