Description

Technical Field

[0001] The utility model relates to the technical field of oropharyngeal ventilator equipment, in particular to a stable multifunctional oropharyngeal ventilator. Background Art

[0002] The existing conventional oropharyngeal ventilation tubes generally have the following problems in clinical use:

[0003] First, the stability after fixation is poor, the bite under the wing edge is easily damp and difficult to fix, and the risk of the oropharyngeal airway falling out is high; especially for mentally ill patients who are agitated and have a tendency to bite their tongue (the oropharyngeal airways used clinically are fixed in a straight line with two points).

[0004] Secondly, the comfort level is poor. Clinically, adhesive tape or cotton tape is commonly used for fixation. The disadvantages are as follows: the bite under the wing edge is easily damp and irritates the skin; the method of wrapping cotton tape or adhesive tape around the bite and tying knots to fix it is easy to rub the lip mucosa, and even damage the mucosa and leave obvious marks; the cotton tape is fixed behind the neck, which is affected by pressure, friction, and shear force, increasing the risk of pressure injury; adhesive tape fixation is prone to cause allergies.

[0005] Then, the use process requires high patient cognition, self-awareness, and cooperation. Ordinary oropharyngeal ventilators are often used to maintain upper airway patency in patients under general anesthesia or patients with retroglossia, assist comatose patients in oropharyngeal suction, and are used as dental pads to prevent biting of tracheal intubation during the recovery period. However, when encountering special patients (mental disorders, cognitive disorders, delirium) who are extremely uncooperative and unable to communicate effectively, ordinary oropharyngeal ventilators often cannot meet clinical needs. Utility Model Content

[0006] The utility model aims to solve the problems of poor stability, poor comfort and single function of the existing conventional oropharyngeal ventilator after being fixed in clinical use, and proposes a stable multifunctional oropharyngeal ventilator.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A stable multifunctional oropharyngeal ventilator is designed, comprising an oropharyngeal ventilator and a silicone four-head belt, wherein the oropharyngeal ventilator and the silicone four-head belt are used in conjunction with each other, and are characterized in that:

[0009] The oropharyngeal ventilation tube includes an integrated ventilation bite inner core, a wing, a positioning column, a gel cheek support pad and a pharyngeal bend. The integrated ventilation bite inner core includes a ventilation interface and a reinforcement inner ring. The ventilation interface is fixedly installed on the upper part of the reinforcement inner ring. The reinforcement inner ring is arranged in the middle of the wing through intermittent plug-in connection. Four positioning columns are fixedly installed on the upper part of the wing. The side of the wing is fixedly installed with a gel cheek support pad. The lower part of the wing is fixedly connected and installed with a bite. The lower part of the bite is fixedly connected and provided with a pharyngeal bend.

[0010] The silicone four-head band includes a rectangular grid surface and four silicone bands, four silicone bands are fixedly installed on both sides of the rectangular grid surface, and a plurality of clamping holes are opened at equal intervals on the four silicone bands;

[0011] The plurality of the locking holes and the four locking columns are installed in coordination with each other for use.

[0012] Preferably, the flange is intermittently matched with the reinforced inner ring to prevent swallowing and excessive insertion.

[0013] Preferably, the width of the occlusal portion of the bite that contacts the teeth is sufficient to contact two to three teeth, and the occlusal pressure of the teeth can be evenly distributed to the contacted teeth.

[0014] Preferably, the pharyngeal curvature is entirely placed in the patient's oral cavity, with the concave surface fitting against the tongue surface, and the depth can reach the posterior pharynx.

[0015] Preferably, the gel cheek support pad is a soft elliptical sphere, which is placed outside the corner of the mouth and can fill the gap between the wing edge and the cheek at the corner of the mouth to prevent the pharyngeal curvature from shaking left and right in the oral cavity and improve stability.

[0016] Preferably, the flange is a white oval solid plastic sheet with a thickness greater than 1.5 mm.

[0017] Preferably, the inner core of the integrated ventilation bite can enhance the hardness of the bite to prevent the patient from biting the tube body, and can seamlessly connect the ventilation interface to ensure effective ventilation.

[0018] The utility model provides a stable multifunctional oropharyngeal ventilator, which has the following beneficial effects:

[0019] First, after inserting the oropharyngeal ventilation tube of the present design, the ventilation effect of directly connecting a simple respirator on the premise that the airway has been opened is better than that of a simple respirator connected to a mask. Moreover, directly connecting a simple respirator on the premise that the airway has been opened is simpler and more labor-saving for medical staff to open the airway with one hand than with a simple respirator connected to a mask.

[0020] Secondly, fixation above the flange surface also prevents oral moisture from wetting the fixation band, keeping the fixation band and the skin clean and dry;

[0021] Then, the rectangular grid surface of the four-head fixation belt is supported on the patient's head, the force-bearing surface is evenly distributed, and there are hair intervals for protection, which disperses the pressure and friction; the widened flanges on the left and right sides can reduce the contact area between the fixation belt and the cheek, and the area where the skin on the outer edge of the cheek contacts the four-head strap can be protected with gauze or a thin cotton pad to avoid damage to the skin due to shear force. At the same time, a silicone four-head strap is used for fixation, which reduces the irritation of the tape to the skin and causes adverse reactions such as allergies.

[0022] Then, four rectangular elastic bands are pressed down from the wing edge to fix the tube. Not only is the stability stronger than that of ordinary oropharyngeal ventilation tubes, but the tightness of the bands can be adjusted according to the degree of cooperation of the patient, which takes into account the personalized needs while ensuring the safety of the tube. It is especially suitable for the treatment of mental disorder patients with tongue biting in the acute stage. BRIEF DESCRIPTION OF THE DRAWINGS
