It is used to place the patient's tongue in the patient's mouth and open the patient's tongue to form a ventilation channel between the tongue and the posterior wall of the pharynx. When the upper airway of the patient is obstructed, the pharyngeal insertion part of the mouth support glossopharyngeal body 2 is placed in the patient's oral cavity, which can quickly establish an airway and ensure the patient's ventilation safety. When the upper airway of the patient is obstructed, if the patient breathes spontaneously, it is only necessary to place the flue insertion part of the mouth-supporting glossopharyngeal body 2 into the patient's oral cavity to relieve the obstruction, and oxygen inhalation or no oxygen inhalation depends on the condition. If the patient is not breathing spontaneously, mechanical ventilation equipment, such as anesthesia machine, ventilator and simple breathing apparatus, should be used to implement assisted ventilation for the patient. Most patients with upper airway obstruction have reduced tidal volume or even no spontaneous breathing. They need oxygen inhalation, or even need to inhale oxygen and implement assisted ventilation at the same time, otherwise the oxygen demand cannot be met.

Oxygen inhalation mask body 1 is required for both oxygen inhalation and non-invasive assisted breathing. Oxygen inhalation mask body 1 can produce the maximum concentration of oxygen inhalation effect from the minimum oxygen flow rate; oxygen inhalation mask body 1 can provide a sealed environment for the patient's nose and mouth, which Non-invasive assisted breathing provides the necessary conditions. In order to facilitate oxygen inhalation and prevent the oxygen mask body 1 from falling off, and at the same time, in order to fix the mouth support glossopharyngeal body 2 and prevent the mouth support glossopharyngeal body 2 from coming out, a mask connecting part is provided at the end of the mouth support glossopharyngeal body 2 21. The pharyngeal body connecting port 11 is provided in the oxygen inhalation mask body 1, and the mask connecting portion 21 and the pharyngeal body connecting port 11 are matched in size and shape, so that when the mask connecting portion 21 is embedded in the pharyngeal body connecting port 11, it can be The mouth brace tongue and pharynx body 2 is temporarily fixedly connected with the oxygen inhalation mask body 1 . When the oxygen inhalation mask body 1 and the mouth support glossopharyngeal body 2 are connected as a whole, to prevent the oxygen inhalation mask body 1 and the mouth support glossopharyngeal body 2 from falling off, it is only necessary to connect the oxygen inhalation mask body 1 or the mouth support glossopharyngeal body 2. Body 2 can be fixed. For example, the oxygen inhalation mask body 1 can be fixed on the patient's head and face with the most common headband in the hospital. In this way, an efficient oxygen supply can be provided to the patient through the oxygen inhalation mask body 1 , and the upper airway obstruction of the patient can be relieved through the mouth-supporting glossopharyngeal body 2 .

Different patients have different oropharynx depths. In order to meet the needs of different patients, the length of the mouth brace body 2 can be adjusted, and the length of the pharynx body 2 can be adjusted by using a retractable rod or other methods. As shown in FIG. 1 , FIG. 2 and FIG. 3 , the length adjustment mechanism 3 is used for the implementation of length adjustment. The length adjustment mechanism is located between the pharynx insertion part and the mask connecting part 21 . The length adjustment mechanism 3 can appropriately adjust the length of the mouth support glossopharyngeal body 2 to adapt to the deep oral cavity of different patients.

There are many options for the length adjustment mechanism 3, and the embodiment of FIG. 3 is described in detail here. The length adjusting mechanism includes a first adjusting arm 31 for connecting the mask connecting portion 21 and a second adjusting arm 32 for connecting with the pharyngeal tract insertion portion;

A sliding sleeve 321 is provided on the second adjusting arm 32 , the first adjusting arm 31 can be sleeved in the sliding sleeve 321 to slide, and also includes a sliding sleeve for locking the positions of the first adjusting arm 31 and the second adjusting arm 32 locking mechanism.

The sliding locking mechanism includes an adjusting tooth 311 arranged on the first adjusting arm 31 and an elastic fixing strip 322 arranged on the sliding sleeve 321 and can abut against the adjusting tooth 311. An adjustment arm 31 is distributed in the length direction, the elastic fixing strip 322 can swing on the sliding sleeve 321 , and when the elastic fixing strip 322 swings, the elastic fixing strip 322 can be separated from the adjusting tooth 311 .

In the embodiment of the present invention, the elastic fixing clips 322 are naturally held in the adjusting clips 311 when there is no force. When the length of the mouth brace glossopharyngeal body 2 needs to be adjusted, the pulling second adjusting arm 32 is adjusted downward, because the inclination direction of the adjusting tooth 311 is downward, and the elastic fixing strip 322 is lifted up by force and enters the next level adjusting tooth 311 until the adjustment ends. Since the mouth-supporting glossopharyngeal body 2 is subjected to upward force during normal use, it only needs to be adjusted downwards during adjustment, and the second adjustment arm 32 needs to be moved to the upper limit when the adjustment is completed. In this way, the length adjustment mechanism 3 can appropriately adjust the length of the mouth-supporting glossopharyngeal body 2 to adapt to the depth of the oral cavity of different patients, so as to achieve the best use effect, so that the patient can quickly re-establish the breathing channel when the upper airway is blocked, and Assisted breathing is provided for the patient through the oxygen inhalation mask body 1 . In a specific implementation, the end of the first adjusting arm 31 is further provided with limit teeth 312 , the direction of the limit teeth 312 is opposite to the direction of the adjustment teeth 311 and the limit teeth 312 are higher than the adjustment teeth 311 .

Further, as shown in Figure 1, Figure 2 and Figure 6, in order to meet the anesthesia requirements of patients undergoing gastroscopy and upper respiratory tract examination, the mouth support glossopharyngeal body 2 is provided with a tooth opening ring 22, and the teeth support The inner diameter of the open ring 22 is greater than 10 mm. Through the tooth-opening ring 22, the mouth-pulling glossopharyngeal body 2 can be fixed by cooperating with the patient's teeth. The fixing principle of the tooth opening ring 22 is as follows: the middle part of the tooth opening ring 22 is provided with a depression, the outer side of the depression is provided with a tooth baffle 221, and the patient's teeth are bitten in the corresponding depression, so as to prevent the mouth support glossopharyngeal body 2 from being in the patient's mouth. Pharyngeal slip. At the same time, an operation tool insertion port 220 is provided in the middle of the tooth opening ring 22. The operation tool insertion port 220 can prevent the upper and lower teeth of the patient from occluding. During bronchoscopy and gastroscopy, expensive instruments enter the patient's mouth through the operation tool insertion port 220. Avoid tooth closure and bite of expensive instruments caused by the patient's involuntary resisting action.

In order to facilitate the use in gastroscopy and bronchoscopy, as shown in FIG. 7 , the pharyngeal insertion part of the mouth-supporting glossopharyngeal body 2 is a flat arc-like section, and the middle of the arc-like section forms the glossopharyngeal pharynx The airway 23 has a ventilation cavity 230 in the glossopharyngeal airway 23 . The advantage of setting the mouth support glossopharyngeal body 2 as an oblate shape is to minimize the occupation of the space in the oral cavity, and the oral cavity space is rich in width and narrow in height, and the oblate glossopharyngeal airway 23 can In the case of not occupying height, the ventilation area of the same size can be achieved, which saves space for gastroscope or bronchoscope and is convenient for surgeons to operate. Of course, in order to make the upper and lower shapes of the mouth-supporting glossopharyngeal body 2 more consistent and increase the aesthetics of the appearance, as shown in FIG. It is arranged in a structure similar to the oblate glossopharyngeal airway 23 , and the mouth brace glossopharyngeal body 2 is provided with a corresponding ventilation cavity. The glossopharyngeal airway 23 is communicated with the operation tool insertion port 220, and the operation tool enters the glossopharyngeal airway 23 through the operation tool insertion opening 220, and is then inserted into the patient's oral cavity.

As shown in FIG. 4 , the oxygen inhalation mask body 1 is provided with an oxygen inhalation tube 12 . In some patients with upper airway obstruction, such as: patients with upper airway obstruction just after extubation of anesthesia, although the upper airway obstruction can be relieved through mouth support of the glossopharyngeal body 2, the patient retains spontaneous breathing, but the oxygen demand is still insufficient. By having the oxygen inhalation tube 12, a high-concentration airflow can be provided in the mask, so as to improve the oxygen supply of the patient and increase the safety. A cassette switch 120 is provided on the oxygen inhalation tube 12 .

Further, the oxygen inhalation mask body 1 is provided with a respirator connecting pipe 13 and a respirator pipe blocking body 130 matching the respirator connecting pipe 13, and the joint of the respirator connecting pipe 13 and the oxygen inhalation mask body 1 forms a pharynx. When the mask connecting part 21 is embedded in the pharyngeal body connecting port 11, the respirator connecting pipe 13 communicates with the inner cavity of the oxygen inhalation mask body 1 through the connecting part through hole passing through the mask connecting part 21. When the patient has apnea or severely insufficient tidal volume, such as induction of general anesthesia, the patient needs to be provided with assisted breathing through a ventilator. The arrangement of the respirator connecting pipe 13 provides convenience for connecting the oxygen inhalation mask body 1 to the respirator. At present, all respirators, including anesthesia machines, ventilators, and simple respirator, have the same interface specifications, which is more convenient. The purpose of setting the matching respirator tube blocking body 130 is: when the patient only needs to inhale oxygen and does not need a mask to assist breathing, the respirator tube blocking body 130 can be used to block the respirator connecting tube 13 to avoid oxygen entering the oxygen inhalation mask body 1 . The flow escapes quickly, increases the oxygen concentration in the oxygen inhalation mask body 1, improves the oxygen inhalation treatment effect, and increases the safety.

In order to improve the efficiency of gastroscopy and upper respiratory tract examination, avoid uninterrupted examination when upper respiratory tract obstruction or respiratory depression occurs in patients during anesthesia, and ensure that patients can perform assisted breathing.
