Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to an oropharyngeal ventilation tube. Background Art

[0002] The oropharyngeal airway is a non-tracheal tube ventilation tube. It is simple to operate and easy to master. It is a medical device that can quickly open the trachea within seconds without special equipment. The oropharyngeal airway mainly includes a tube body and a wing. The inside of the tube body is the airway. The tube body includes a dental pad part and a pharyngeal bend part. When using it, choose a suitable catheter, assist the patient to take a supine position, tilt the head back, so that the mouth, pharynx, and throat are in a straight line; then the pharyngeal bend part is directly inserted close to the hard palate. The ideal position of the nasopharyngeal airway after placement is: after inserting from the patient's nasal cavity to the pharyngeal cavity, the pharyngeal end is 0.5cm outside the glottis. Such a position can support the posterior pharyngeal wall, thereby relieving upper airway obstruction and keeping the airway open. During the use of the oropharyngeal airway, the pharyngeal bend often fails to reach the root of the tongue, resulting in the inability to open the trachea; in addition, since the oropharyngeal airway requires a certain hardness, it is easy to cause damage to the throat during use, which leads to pharyngeal bleeding. Summary of the invention

[0003] The present invention is intended to provide an oropharyngeal ventilator to solve the problem in the prior art that the oropharyngeal ventilator cannot open the trachea because the pharyngeal curved portion does not reach the tongue root.

[0004] An oropharyngeal ventilation tube in the present scheme includes a wing and a tube body, one end of the tube body is fixedly connected to the wing; an air bag is wrapped on the outer wall of the tube body, the air bag is located at the end of the tube body away from the wing, the air bag is connected to the trachea, and the trachea is connected to an inflation cylinder.

[0005] The working principle and beneficial effects of this solution are as follows: when using, choose a suitable catheter, assist the patient to assume a supine position, tilt the head back, and make the mouth, pharynx, and larynx form a straight line; then directly insert the curved part of the pharynx close to the hard palate; after the tube body is inserted, inflate the air bag through the inflation tube, and after the air bag is inflated, the tongue is lifted to keep the respiratory passage open. At the same time, the air bag is propped up to reduce the direct contact between the tube body and the pharynx and larynx, and the air bag itself is relatively soft, which helps to avoid damage to the pharynx and larynx caused by the tube body.

[0006] Furthermore, an annular groove is provided at the end of the flange, and the groove extends into the wall of the tube body through the flange, and the groove extends to the end of the tube body away from the flange; a one-way air intake valve is provided on the tube body, the air intake end of the one-way air intake valve is connected to the air bag, and the air outlet end of the one-way air intake valve is connected to the airway of the tube body; two spacers are provided in the groove, and the spacer on the same side as the one-way air intake valve is provided with an opening for the one-way air intake valve to pass through, and there is a gap between the two spacers and the wall bodies on both sides of the groove; a through hole for the spacer to pass through is provided on the wall body between the groove and the airway of the tube body.

[0007] During the use of the oropharyngeal ventilation tube, sputum and other dirt are easily accumulated on the inner wall of the tube body, and a large amount of dirt is easily accumulated, which can easily lead to blockage of the airway of the tube body. By providing grooves, septa and one-way air inlet valves, the dirt in the airway of the tube body can be cleaned regularly. When in use, push the septum, and the ends of the two septa away from the flange pass through the through hole and are connected together to close the airway of the tube body. At the same time, the airbag is inflated by the inflation cylinder, and the gas in the airbag enters the airway of the tube body through the one-way air inlet valve. Under the action of the gas, the dirt moves along the airway toward the flange, thereby achieving the purpose of removing the dirt. In the process of removing dirt, oxygen can be delivered to the human body through the groove. Since there is a gap between the septum and the walls on both sides of the groove, the patient's normal breathing can be guaranteed.

[0008] Furthermore, the end of the flange is provided with a buckle cover that buckles with the groove. By providing the buckle cover, when the airway of the pipe body does not need to be decontaminated, the buckle cover can be used to keep the groove at one end of the flange closed, which is conducive to keeping the groove clean.

[0009] Furthermore, the tube body is provided with scales, through which the length of the tube body entering the pharynx and larynx of the patient can be intuitively seen, making the use safer and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following is further described in detail through specific implementation methods:

[0013] The reference numerals in the drawings of the specification include: flange 1, inflator 2, air tube 3, tube body 4, air bag 5, groove 6, one-way air inlet valve 7, buckle cover 8.

[0014] Embodiment 1:

[0015] Basically as attached Figure 1 As shown: an oropharyngeal ventilation tube 3, including a flange 1 and a tube body 4, one end of the tube body 4 is fixedly connected to the flange 1; an air bag 5 is wrapped on the outer wall of the tube body 4, the air bag 5 is located at the end of the tube body 4 away from the flange 1, the air bag 5 is connected to the trachea 3, and the trachea 3 is connected to the inflation cylinder 2.

[0016] When in use, select a suitable tube body 4, assist the patient to lie flat, tilt the head back, and make the mouth, pharynx and larynx form a straight line; then put the pharyngeal curved part of the tube body 4 directly into close to the hard palate; after the tube body 4 is put in, inflate the air bag 5 through the inflation tube 2, and after the air bag 5 is inflated, lift the tongue to keep the respiratory passage open.

[0017] Embodiment 2:

[0018] Basically as attached Figure 2 As shown: the difference from Example 1 lies in that: an annular groove 6 is provided at the end of the flange 1, and a buckle cover 8 which is buckled with the groove 6 is provided at the end of the flange 1; the groove 6 extends into the wall of the tube body 4 through the flange 1, and the groove 6 extends to the end of the tube body 4 away from the flange 1; a one-way air intake valve 7 is provided on the tube body 4, the air intake end of the one-way air intake valve 7 is connected to the air bag 5, and the air outlet end of the one-way air intake valve 7 is connected to the airway of the tube body 4; two spacers are provided in the groove 6, and the spacer on the same side as the one-way air intake valve 7 is provided with an opening for the one-way air intake valve 7 to pass through, and there is a gap between the two spacers and the wall bodies on both sides of the groove 6; a through hole for the spacer to pass through is provided on the wall body between the groove 6 and the airway of the tube body 4; and a scale is provided on the tube body 4.

[0019] The specific implementation process is as follows: Taking Example 2 as an example, when using, select a suitable tube body 4, assist the patient to take a supine position, tilt the head back, and make the mouth, pharynx, and larynx form a straight line; then the pharyngeal curved part of the tube body 4 is directly placed close to the hard palate. During the process of placing the tube body 4, the length of the tube body 4 placed in the pharynx and larynx can be intuitively understood through the scale on the tube body 4; after the tube body 4 is placed, the airbag 5 is inflated through the inflator 2. After the airbag 5 is inflated, the tongue is lifted to keep the respiratory passage unobstructed. After the oropharyngeal ventilation tube 3 has been used for a period of time, the buckle cover 8 is opened, and the diaphragm is pushed so that the ends of the diaphragm are connected together through the through holes on the wall and the airway is sealed. Then, the airbag 5 is inflated through the inflator 2, and the gas in the airbag 5 enters the airway of the tube body 4 through the one-way air inlet valve 7. Under the action of the gas, the dirt moves along the airway toward the flange 1, thereby achieving the purpose of removing the dirt. In the process of removing dirt, oxygen can be delivered to the human body through the groove 6. Since there is a gap between the partition and the walls on both sides of the groove 6, normal breathing of the patient can be guaranteed.
