Description

Laryngeal mask with throat spraying device

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a take laryngeal mask of atomizer of throat.

Background

The number of asthma patients in China is nearly 3 million, which accounts for 1/10 of asthma population all over the world and is the first to live all over the world. The average age at which asthma occurs is 4 years of age, with about 20% of children presenting with symptoms within 1 year of age. The probability of occurrence of laryngeal spasm and bronchospasm during the surgical anesthesia of asthma patients is 0.17% -4.2%. When asthma and bronchospasm occur in operation of a patient, except for intravenous administration, the inhalation therapy can enable the medicine to directly act on the respiratory tract and the lung, the curative effect is direct, the side effect is low, and the most effective treatment mode for treating the asthma is provided. When asthma or bronchospasm occurs in the operation of a patient ventilated by the laryngeal mask, the therapeutic drug is sprayed in through the catheter, so that the therapeutic drug cannot go deep into the throat, the spraying effect is poor, and the drug cannot be well transmitted. There is a need for an improved laryngeal mask that provides an effective delivery path for medicaments to be dispensed into the larynx, thereby providing a guarantee for intraoperative dispensing of asthma treatment medications or prevention of bronchospasm.

The Chinese patent application: CN205903500U discloses a take two-chamber trachea cannula of spraying pipe, and it includes the main part pipe, and left branch pipe and right branch pipe are connected to main part pipe upper end, and main cuffed tube middle part is equipped with main cuffed tube, right branch pipe lower extreme is equipped with the flexion, is equipped with vice cuffed tube on the flexion. A left inflation tube is arranged in the tube wall of the left branch tube, the lower end of the left inflation tube is communicated with the main cuff and the auxiliary cuff, a right inflation tube is arranged in the tube wall of the right branch tube, the lower end of the right inflation tube is communicated with the main cuff and the auxiliary cuff, aluminum alloy wires distributed in a spiral shape are arranged on the inner wall of the main tube, and the aluminum alloy wires are positioned between the main cuff and the auxiliary cuff; the spraying device is characterized in that a spraying guide pipe made of food-grade plastics and connected with a spraying power device at the tail part is arranged in the pipe cavity of the bending part, and the top of the spraying guide pipe is provided with a spraying head capable of spraying plane mist-shaped small droplets. The drug delivery device can deliver and atomize the drug into the bronchial side wall at the far end of the tracheal cannula while artificial ventilation is carried out, so that the drug can be more easily insufflated into the bronchiole at the far end of a patient, and more ideal drug effect can be obtained. However, the administration device only aims at the stimulation between the prior tracheal catheter and the trachea which is in direct contact with the prior tracheal catheter to reduce the pain of the patient with the tracheal catheter, does not change the patient with asthma and bronchospasm, and can not solve the problems that the medicine can not be sent to the throat in time, the medicine spraying effect is poor and the like when the patient with laryngeal mask ventilation suffers from asthma or bronchospasm in the operation.

Retrieving the chinese patent application: CN2681760Y discloses a laryngeal mask, which is composed of a mask (an inflatable or deflatable rubber belt bag), an air duct, a mask inflation tube, and the like. One end of the vent pipe is connected with a cover, and the other end of the vent pipe is connected with a male connector. The cover is inflated or deflated through the cover inflation and deflation pipe, the inflation indicating bag and the inflation and deflation valve. The mask is contoured to the laryngo pharynx to fit within the laryngo pharynx. The inflated mask fills the laryngo pharynx and forms a seal. The central opening of the inner circle of the cover is an oval wide opening, has no separation band, faces to the laryngeal cavity, and is communicated with the ventilation tube so as to be beneficial to ventilation or the rubbing of the flexible bronchoscope. The device mainly provides a safe and convenient airway processing device which does not need to use a direct laryngoscope to assist the laryngoscope to be placed into a laryngeal tube, reduces the occurrence of the incomplete situation of cardiopulmonary reaction of a patient or oxygen inhalation of a breathing mask caused by tracheal intubation, but when the laryngeal mask ventilates the patient and asthma or bronchospasm occurs, therapeutic drugs are sprayed in the laryngeal mask through a catheter, the therapeutic drugs cannot go deep into the throat, the spraying effect is poor, and the drugs cannot be transmitted well. The laryngeal mask and the intubation tube are improved to provide an effective delivery path for the medicine sprayed into the larynx of the patient, thereby providing guarantee for spraying asthma treatment medicine or preventing the occurrence of bronchospasm during the operation.

In view of the above, there is a need for a laryngeal mask with a laryngeal spray device that can maintain the respiratory function of a patient and also address asthma or bronchospasm in the patient, and no report on such a novel laryngeal mask is available.
