Technical Field

The utility model belongs to the technical field of the endotracheal tube technique and specifically relates to a tracheal catheter external member device that can go atomizing and pipe wall fan spout injection medicine simultaneously.

Background

In modern medicine, general anesthesia is increasingly used in clinic, comfort and safety of general anesthesia are widely accepted and accepted by anesthetists and patients, the proportion of general anesthesia is increased year by year, and more than 80% of general anesthesia is used in developed areas and partial three-level hospitals in China. The effective respiratory channel establishment and respiratory control of the tracheal intubation general anesthesia can solve the oxygen supply of patients to the maximum extent, especially long-time operation becomes a necessary choice, and the comfort and safety of the general anesthesia operation are ensured.

However, general anesthesia with endotracheal intubation has certain disadvantages in some aspects, both short-term and long-term, and patients with general anesthesia surgery, particularly elderly, obese, chronic obstructive pulmonary disease, airway hyperresponsiveness and prolonged mechanical ventilation, have pulmonary complications such as atelectasis, pulmonary inflammation and infection, and airway hyperresponsiveness and spasm induced by tracheal tube stimulation to airway sometimes occur, which cause some overt and potential risks and complications, increasing perioperative mortality.

Because the tracheal catheter is inserted into the glottis and the air passage, the patient can be very difficult to tolerate in the waking period or the patient needs to take the tracheal catheter to a diseased region for respiratory support, the stimulation of the catheter to the upper part, the lower part and the throat of the glottis often causes the patient to be extremely uncomfortable and uncomfortable, thereby causing the heart rate to be greatly increased, the blood pressure to be greatly increased, the stimulated trachea can induce airway hyperreaction and even asthma attack to cause certain cardiovascular and respiratory system complications, the increase of the blood pressure in the waking period is easy to induce the secondary bleeding of wound surfaces, particularly, the sudden increase of the blood pressure can induce the risk of secondary bleeding of hemostasis points in special operations such as brain surgery, nasal cavity surgery and the like, the consequences are very serious, meanwhile, the tracheal catheter is also very unsafe for the patient with cardiovascular and respiratory system diseases and is easy to induce cardiovascular and cerebrovascular accidents, while the number of the patients with heart and lung diseases in non-heart surgery is very large, along with the aging acceleration and the, the number of operations that such patients undergo is also increasing; the difficulty of patients requiring long-term tracheal tube breathing support in a monitoring room is self-evident, many patients and families choose to give up treatment due to the difficulty of placing tracheal tubes, and patients who have a similar tracheal tube treatment experience also have psychological shadows. In clinical practical work, the adverse reflection of the tracheal catheter inserted into the airway is inhibited by frequent drug sedation, but the use of the drug not only increases the cost and the metabolic burden of organs, but also is not favorable for disease observation and recovery, inhibits the cough reflection of patients, is not favorable for sputum excretion and autonomous functional exercise of the lung, and has more defects. For the continuous development of modern medicine, the ERAS quick rehabilitation concept is rapidly promoted, for the arrangement of an operating room, the operation is more and more, the turnover efficiency is also improved, the increase of general anesthesia also discovers that the number of postoperative atelectasis of patients is increased, the atelectasis is particularly common in the elderly patients, the obese patients and the like, the whole rehabilitation and the prognosis are directly influenced, complications and death rate are increased, the occurrence of atelectasis can be effectively reduced by timely and effectively atomizing and sucking the medicaments such as bronchiectasis and the like into the lung in the perioperative period, particularly in the early period, and the lung function recovery is promoted, the measure forms expert consensus and guidance in the surgical fields such as thoracic surgery in recent years, and the like, therefore, the invention provides a multifunctional tracheal catheter set device which can simultaneously atomize and suck oxygen and can also inject local medicaments through a tracheal catheter to relieve the reaction of the patients on the tracheal cannula, and simultaneously has no bacteria requirement in the operation, the head of a patient often needs to be wrapped or covered by a heavier dressing sheet, and in addition, the head of the patient is in a special body position of partial operation such as lying on side, lying prone and the like, the firmness of the fixation of the traditional adhesive plaster can be directly influenced by oral secretion and facial grease secretion, the adhesive plaster has no stickiness after being soaked by the secretion, the tracheal catheter is easy to shift and even separate, fatal risks are caused to the operation safety, the medicine injection on the tube wall of the tracheal catheter can be influenced by the change of the position of the catheter, the dosage and the effect are influenced, so that the tooth cushion matched with the tooth cushion is designed to be very necessary for strengthening the firmness of the tooth cushion, the tooth cushion can play an obvious and stable role for the patient needing to take the tube to a ward for respiratory support, the nursing workload can be effectively reduced, and the occurrence of adverse events such as unconscious tube drawing and the like of the patient under the condition of accidental separation of.
