Description
Technical Field
The invention relates to a medical instrument used for tracheal intubation operation, in particular to a tracheal intubation with sputum suction and medicine injection functions and a tracheal intubation component consisting of the tracheal intubation and other components, which can realize the collection of endotracheal anesthesia, cleaning, inflammation diminishing and sputum samples.
Technical Field
At present, the establishment of artificial respiration channels through the operation of endotracheal intubation is the most effective, mature and most commonly used technical means for emergency treatment and rescue and nursing of critical patients. The trachea cannula is a key surgical instrument for establishing an artificial respiratory pipeline in the trachea cannula operation, and is a necessary medical instrument in the first aid and critical patient rescue and protection processes.
Patients who carry out tracheal intubation are mostly critical patients under emergency situations, sputum is easily produced by the patients, and the sputum spitting function of the patients is very low. Meanwhile, as the patient cannot spit by himself during the establishment of the artificial respiration channel, the sputum of the patient is greatly increased due to the stimulation of the inserted artificial respiration channel to the tracheal mucosa of the patient. At present, during the endotracheal intubation, a sputum suction tube is manually inserted at certain intervals to suck and clean sputum generated at the throat part of a patient. This causes discomfort to the patient and injury to the tracheal mucosa of the patient due to the insertion of the sputum-aspirating tube for many times, and also causes a great deal of work and difficulty for the nursing of medical care personnel, and causes many physical and psychological injuries to the patient and family members.
Usually, the sputum produced by the patient needs to be removed from the air bag to the Murphy's eye end of the artificial respiration channel in the patient and from the air bag to the external end of the patient.
Sputum from an air bag in a patient body to the Murphy's eye end is inserted into the sputum suction tube through the artificial respiration channel to be removed, the sputum suction tube is relatively easy to insert, and the risk of injury to the respiratory mucosa of the patient is relatively low.
Sputum in the artificial respiration channel of the patient from the air bag to the external end of the body needs to be cleared by inserting a sputum suction tube between the artificial respiration channel and the respiratory tract of the human body. The sputum suction pipe is difficult to insert due to the limitation of the artificial respiration channel and the human respiratory tract, and the risk of stimulation and damage to the human respiratory tract mucous membrane during intubation is greatly increased.
In addition, such patients often experience complications during the establishment of the artificial respiratory tract, such as choking, nausea, vomiting, throat infection, etc. These complications can be very detrimental to patient control and, in severe cases, can be directly life threatening to the patient. In order to reduce the uncomfortable reactions and infection probability of cough, nausea and vomiting of a patient and reduce intubation complications, medical staff often injects narcotic drugs, anti-inflammatory drugs, cleaning fluids and the like to the glottis of the trachea, and the drug injection nursing means is proved to be effective at present, but no instrument capable of conveniently and effectively realizing the function exists in current clinical operation.
Also, such patients are often clinically analyzed by sputum sampling assays. Can cause the pollution of sputum sample because of sputum and external mutual contamination often clearing away patient's sputum and sample process, cause the influence to the accuracy of sputum chemical examination analysis.

firstly, extruding a first sputum suction tube and a straight tube with an inflation channel and a drug injection channel in the tube wall by using precision extrusion equipment, then processing and forming an accommodating groove and inlets and outlets of the inflation channel and the drug injection channel on the tube wall of the straight tube, and then bending the straight tube by using bending and shaping equipment to prepare an arc-shaped intubation main body;
forming the air bag and the bag bodies of the two medicine injection bags by using a balloon blowing forming machine;
a first sputum suction pipe is embedded in the accommodating groove of the intubation main body, and the air bag and the bag bodies of the two medicine injection bags are combined at corresponding positions on the intubation main body, so that the inlet of the first sputum suction pipe is positioned between the two medicine injection bags;
the capsule body of the medicine injection capsule is provided with small medicine injection holes.
