Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a blocking device for a tracheal cannula.
Background
The patient must have an artificial airway for continuous ventilator use for various reasons, such as respiratory failure, cerebral hemorrhage, after cardiac arrest, heart failure, etc.
Tracheotomy mainly refers to an operation of artificial ventilation by cutting a neck trachea, putting a plastic or metal catheter and connecting the plastic or metal catheter with other catheters, which is one of important measures for relieving upper respiratory tract obstruction and respiratory muscle paralysis patients. Such as 1) acute and chronic laryngeal obstruction, anoxia, asphyxia caused by laryngeal obstruction, laryngeal inflammation, tumor, foreign body, trauma or scar stenosis; 2) lower airway secretion obstruction; 3) a breathing machine is applied for a long time to assist breath absorption and preventive tracheotomy; 4) other factors are that some patients who need intratracheal anesthesia but can not be intubated through mouth and nose, and those who can not take out the foreign body in respiratory tract from throat, etc.
The tracheotomy procedure, which is now commonly used in the industry, comprises the following steps:
1) the body position is generally the supine position, a small pillow is arranged under the shoulder, the head is turned backwards, the trachea is close to the skin, the exposure is obvious, and the operation is facilitated; the assistant sits on the head side to fix the head and keep the middle position; sterilizing conventionally, and spreading sterile towel;
2) local anesthesia, namely, the central anterior cervical part, the upper part, from the lower edge of the thyroid cartilage to the suprasternal fossa, is infiltrated and anesthetized by lidocaine, and the anesthesia can be avoided for patients who are unconscious, critically ill or asphyxia;
3) incision, which is mainly a straight incision (a transverse incision can be used for general anesthesia patients), from the lower edge of the thyroid cartilage to the position close to the suprasternal fossa, and skin and subcutaneous tissues are incised along the anterior median line of the neck;
4) separating the tissues in front of the trachea, namely separating sternum hyoid muscles and sternum thyroid muscles along the midline by using a vascular clamp, exposing the isthmus of the thyroid gland, slightly separating the isthmus at the lower edge if the isthmus is too wide, pulling the isthmus upwards by using a small hook, and clamping, cutting and suturing the isthmus if necessary so as to expose the trachea. In the separation process, the two draw hooks are applied with force uniformly, so that the operation visual field is always kept at the midline, and the fingers are often used for probing whether the cricoid cartilage and the trachea are kept at the middle position;
5) after the trachea is determined, generally at the 2 nd to 4 th trachea rings, 1 to 2 trachea ring front walls are cut in an arc shape from bottom to top by a sharp blade to form a trachea front wall flap (the 4 to 5 ring cutting is performed by low-position tracheotomy), the trachea front wall flap is fixed under the skin after the trachea is inserted (the trachea cannula is pulled out after the operation, the trachea cannula is inserted favorably), and the blade tip is not inserted too deep so as to avoid puncturing the trachea rear wall and the esophagus front wall to cause tracheoesophageal fistula;
6) inserting a tracheal cannula, namely, expanding a tracheal incision by using a curved forceps or a tracheal incision expander, inserting the tracheal cannula which is proper in size and provided with a tube core, immediately taking out the tube core after inserting the outer tube, putting the inner tube into the tracheal cannula, completely sucking secretion, and checking whether bleeding exists or not;
7) and (4) wound treatment, namely, tying a belt on the tracheal cannula to the neck, and tying the tracheal cannula into a dead knot to be firmly fixed. The incision is not generally sutured to avoid causing subcutaneous emphysema, and finally an open gauze pad is arranged between the wound and the sleeve;
the patient through the tracheotomy operation all need block up this tracheal cannula for two or three days before pulling out tracheal cannula, can pull out until the patient can normally breathe, the air flue does not have the below such as obstruction. At present, in clinic, when a patient with tracheotomy needs to block the tracheal cannula, doctors take materials according to places, and manually make objects for blocking the tracheal cannula, so that time and labor are wasted each time, and the disinfection effect cannot be guaranteed; the comfort level of wearing the shoe is not good because the shoe is corrected while being worn; and the recovery process and effect of the patient are not good enough.
