Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a silica gel steel wire reinforced trachea cannula capable of being directly connected with end-expiratory carbon dioxide monitoring.
Background
The trachea cannula is a technique that a special trachea catheter is placed into a trachea through a glottis and is called as trachea cannula, the technique can provide optimal conditions for unobstructed airways, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like, and the emergency trachea cannula technique becomes an important measure in the rescue process of cardiopulmonary resuscitation and critical patients accompanied with respiratory dysfunction. The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely applied, most effective and most rapid means in respiratory tract management, is a basic skill which must be mastered by medical staff, and plays a vital role in rescuing the life of a patient and reducing the fatality rate;
Indication of emergency endotracheal intubation:
firstly, the spontaneous respiration of a patient is suddenly stopped;
secondly, the requirement of ventilation and oxygen supply of the body can not be met, and mechanical ventilation is needed;
thirdly, the patient who can not automatically clear the secretion of the upper respiratory tract and the reflux or bleeding of the content in the stomach sometimes has aspiration;
fourthly, patients with upper respiratory tract injury, stenosis, obstruction, tracheoesophageal fistula and other influences on normal ventilation exist;
acute respiratory failure;
⑥, central or peripheral respiratory failure;
Therefore, the auxiliary or breath control of the tracheal intubation connected with a breathing machine is an important technology which is very commonly used in emergency treatment, intensive care units and general anesthesia operations;
However, the tracheal cannula has the following defects when in use: the breathing tube can not be directly connected with a connector monitored by end-expiratory CO2, and the breathing tube can be connected with the connector monitored by end-expiratory CO2 through an exhaust hole of an elbow in a respirator threaded tube set, so that for infants (especially infants less than 1 year old) and newborns (especially premature infants) with mechanical ventilation through trachea cannula, the small elbow greatly increases invalid cavities during ventilation, and hypercapnia of children patients with type II respiratory failure or laparoscopic surgery and the like is aggravated, and a series of hazards are generated;
Reason (mechanism): the tidal volume of infants and newborns is very small, and is (6-8) ml/kg, and calculated as 7ml/kg for a newborn with a weight of 2.5kg, and the tidal volume is 2.5 × 7-17.5 ml. Whereas the anatomical void space is 30% and 5.25ml, the effective alveolar ventilation in tidal volume is only 17.5 x 70%, i.e. 12.25 ml. However, the exhaust hole of the elbow is connected with the joint monitored by the end-tidal CO2, so that the dead space is increased by about 10ml, namely, the dead space amount is changed to 3 times of the original dead space amount. Children with type II respiratory failure have hypercapnia; children with laparoscopic surgery have difficulty correcting (still uncorrectable by increasing tidal volume and respiratory rate) hypercapnia due to CO2 pneumoperitoneum moving up the diaphragm, reduced lung volume, reduced alveolar ventilation, and CO2 uptake into the blood from the peritoneum. However, the dead space is increased by about 10ml by connecting the exhaust hole of the elbow with a connector monitored by end-tidal CO2, and the expired waste gas remained in the elbow during expiration can be repeatedly inhaled during the next inspiration, so that the arterial blood CO2 level is further increased, and a series of hazards (serious respiratory acidosis, electrolyte disorder, arrhythmia, nervous system inhibition, increased surgical bleeding and the like) caused by hypercapnia are aggravated.
