Description

A type of tracheal intubation with drug addition, sputum suction and temperature measurement

technical field

The invention relates to the technical field of medical devices, in particular to a tracheal intubation tube of a drug-adding, sputum-suction, and temperature-measuring type.

Background technique

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. .

Emergency tracheal intubation technology has become an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. Endotracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and fastest methods in respiratory management. It is a basic skill that medical personnel must master proficiently. to a vital role. And be able to suck out secretions or foreign bodies in the trachea in time, prevent foreign bodies from entering the respiratory tract, keep the respiratory tract unobstructed, carry out effective manual or mechanical ventilation, and perform effective artificial or mechanical ventilation Physiological anatomy of the throat and prevent patients from hypoxia and carbon dioxide retention. , Whether the patient can be transported safely and the prognosis of the patient.

Artificial airway, the use of orotracheal intubation is quick and convenient, and it is more commonly used in the rescue of breathing and cardiac arrest, but it is difficult to fix the orotracheal intubation. Infected, leading to premature extubation and weaning. Appropriate sedation or changing the intubation method for such patients can ensure timely weaning. Nasotracheal intubation is effective and convenient, and it can be tolerated by conscious patients. It is easy to fix, does not affect oral care and eating, and will not cause malnutrition and electrolyte imbalance due to prolonged use. It is a non-invasive method. However, nasotracheal intubation has a large dead space in the airway, which can easily lead to poor drainage of sputum, formation of sputum plugs, and even blockage of the lumen.

During the postoperative care, it is necessary to keep the tracheal tube unobstructed, suck out oral and tracheal secretions in time, pay attention to aseptic operation when suctioning, and strictly separate the oral and tracheal suction tubes. The suction tube and oxygen tube should not exceed 1/2 of the inner diameter of the endotracheal tube, so as not to block the airway. Each time you suck up sputum, do one tube and one glove at a time, and the suction tube stays in the airway for less than 15 seconds.

Keep the airway moist, the concentration of oxygen inhalation should not be too high, generally 1-2 liters per minute is appropriate, and the oxygen inhalation needle is inserted halfway into the endotracheal tube. When the sputum is viscous, inhale it every 4 hours by nebulization, or drip humidification solution into the trachea, 2-5ml each time, no more than 250ml in 24 hours.

The air bag should be tight enough to deflate every 4 hours for 5-10 minutes, and the oropharynx and endotracheal secretions should be sucked up before deflation. Tracheotomy should be considered after the endotracheal tube is retained for 72 hours to prevent the air bag from pressing the tracheal mucosa for a long time, causing mucosal ischemia and necrosis.

In contrast, tracheotomy has small dead space, good fixation, patient tolerance, easy aspiration of sputum, no impact on eating and oral care, and few complications. It is an ideal ventilation method. Tracheotomy is advisable for those who need mechanical ventilation for a long time or those who are in a coma, and those with a lot of sputum and poor sputum discharge.

Sputum suction device: It is mainly used for routine suction and tracheotomy for the wounded and sick, and it is generally electric. It has the characteristics of small size, light weight, great attraction, compact structure, easy to carry, low cost, durable and so on.

There is a sputum suction tube on the sputum suction device, which is used for suctioning sputum and secretions. , The sputum suction tube is routinely disinfected, and the sputum suction device and the sputum discharge tube are disinfected with disinfectant for reuse. The sputum suction device is an indispensable and important tool for preventing and treating the patient's airway obstruction and rescuing suffocation.

Endotracheal intubation refers to the insertion of a special endotracheal tube through the mouth or nose into the patient's trachea. It is a technique for intratracheal anesthesia and rescue of patients, and it is also the most reliable means to keep the upper airway open. Tracheal or endobronchial intubation is a safety measure in administering anesthesia.

Endotracheal intubation has the function of keeping the airway open, easy to remove secretions in the trachea and bronchi; it is convenient to implement assisted breathing and artificial respiration; the anesthesiologist can stay away from the operation area, especially suitable for craniocerebral, maxillofacial, facial features and neck operations; it can reduce respiratory failure The patient's airway dead space is convenient for oxygen inhalation and assisted breathing

Endotracheal intubation plays an important role in the success of the operation. It can ensure the smooth breathing of the patient during the operation and facilitate supplies. At the same time, in order to reduce the stimulation of the trachea to the human body during the operation, it is necessary to occasionally administer medication and clean the trachea of sputum. .
