Plastic rigid visual tracheal catheter core

Abstract

The invention relates to a plastic rigid visual tracheal catheter core. The plastic rigid visual tracheal catheter core comprises a steel pipe, an adjusting shaft, a traction guide wire and a tractionguide wire elbow pipe, wherein the steel pipe is of a hollow structure; the traction guide wire penetrates through the steel pipe; the adjusting shaft comprises a first adjusting shaft, a second adjusting shaft, a third adjusting shaft and a tail end adjusting shaft; the tail end adjusting shaft, the first adjusting shaft, the second adjusting shaft and the front end of the steel pipe are connected end to end; the third adjusting shaft is connected to the rear end of the steel pipe through the traction guide wire elbow pipe; an adjusting handle is arranged at the rear end of the third adjusting shaft; the front end of the traction guide wire is connected with the tail end adjusting shaft; the rear end of the traction guide wire is connected with the adjusting handle. The plastic rigid visual tracheal catheter core provided by the invention has the beneficial effects that the tracheal catheter core is provided with an adjusting shaft structure and the position of a catheter in a trachea of a patient is adjusted through controlling the traction guide wire and the aim of accurately putting the catheter into the trachea of the patient is realized; the plastic rigid visual tracheal catheter core is safe to use and accurate in positioning; a sleeve can be used for realizing positioned injection of a drug and accurate positioned drug administration is realized under the cooperation of a photographing device, so that the treatment effect is improved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a plastic hard visible trachea tube core. Background technique [0002] Endotracheal intubation is one of the medical devices that must be used in rescue of respiratory arrest and general anesthesia in clinical operations. When implementing endotracheal intubation, it is necessary to use a variety of intubation tools to make the endotracheal tube accurately enter the patient's glottis and reach the trachea. In the prior art, copper wires, aluminum wires and hard plastics are mostly used in catheters as plastic supports for soft catheters. Although these catheter cores are adjusted to the required shape outside the patient's mouth, when the catheter enters the patient's mouth, It is easy to deform and differ from the original design, resulting in the inability to accurately enter the patient's trachea. Using a variety of intubation appliances not only delays valuable operation tim...

Problems solved by technology

In the prior art, copper wires, aluminum wires and hard plastics are mostly used in catheters as plastic supports for soft catheters. Although these catheter cores are adjusted to the required shape outside the patient's mouth, when the catheter enters the patient's mouth, It is easy to deform and differ from the original design, resulting in inability to accurately enter the patient's trachea

Using a variety of intubation appliances not only delays valuable operation time, but also may cause iatrogenic infection, and even medical accidents, endangering the lives of patients

In addition, the intubation site will cause discomfort to the patient, and in severe cases, it will cause redness, swelling or inflammation.
