Description

Oropharynx air duct

Technical Field

The utility model relates to an oropharynx air vent belongs to medical care apparatus field.

Background

Oropharynx air duct, also known as oropharynx breather pipe, it is a non-endotracheal tube nature does not have wound ventilation tube, can prevent tongue tenesmus, open the air flue rapidly, make the patient obtain effectual ventilation, oropharynx air duct is a simple and easy convenient supraglottic ventilation unit, prevent tongue tenesmus through pressing down the tongue body, support tongue palatal arch and uvula, separate tongue root and pharyngeal back wall, remove upper respiratory tract obstruction, keep the air flue unobstructed, tracheal cannula patient's general anesthesia induction period before mainly used operation, various stupor patients are because of the upper respiratory tract obstruction that tongue tenesmus leads to and establish interim air flue for the difficult air flue of other types during non-tracheal cannula, be anesthesia department, breathe internal medicine, the necessary air flue management appurtenance of clinical departments such as ICU and emergency department.

The traditional fixing method comprises the following steps: the adhesive fixing bands are fixed on both sides of the cheek in a crossed way. However, this method has the following problems and disadvantages: after the adhesive fixing band is wetted, the viscosity is reduced and is easy to fall off, moreover, because the adhesive fixing band is tightly attached to the skin, hairs of patients are easy to be stuck to cause uncomfortable feeling, even some patients are allergic to the adhesive fixing band, and allergic dermatitis or ulceration is easy to occur at the sticking part. This problem is very annoying to medical workers. For these reasons, clinicians have developed an improved method of attachment by making a small hole in each side of the oropharyngeal airway flange and passing a bandage through the two small holes to attach the bandage around the back of the patient's neck, but this method still has the disadvantage that long-term entanglement can cause discomfort to the patient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at serving the shortcoming that traditional oropharynx air vent fixed effect is not good and arouse the patient discomfort easily for the customer, and then provide an ability self fixed oropharynx air vent.

The utility model discloses a solve the technical scheme that above-mentioned technical problem took and be:

an oropharynx air vent, it includes: flange, bite block, jaw internal fixator, pharyngeal flexion;

the flanges are two semicircular objects which are respectively arranged at the top end of the left side of the tooth pad, are perpendicular to the upper and lower parts of the tooth pad and are smooth in edge, and are arranged outside the lips of the patient and used for fixing the oropharynx air duct;

the jaw internal fixator comprises two semicircular objects which are respectively arranged at a tooth pad and a pharynx bending connection point, are vertical to the tooth pad and have smooth edges; the jaw internal fixator is attached to the internal structure of the oral cavity and arranged in the oral cavity of a patient to play a role in fixing the oropharynx air duct through occlusion of the upper jaw and the lower jaw.

Compared with the prior art, the utility model following beneficial effect has:

the utility model can be fixed at the mouth and the pharynx of a person without harm; the defect that the traditional single-flange oropharynx air duct needs to be fixed externally is overcome, and the defects of easy allergy, easy falling and the like are overcome; simplify the clinical operation steps.

Detailed Description

The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are easily implemented by those having ordinary skill in the art to which the present invention pertains. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In addition, for the purpose of more clearly describing the present invention, parts not connected with the present invention will be omitted from the drawings.

As shown in fig. 1-3, the utility model provides an oropharyngeal airway, including: a flange 1, a bite block 2, a jaw internal fixator 3 and a pharyngeal flexure 4; the flanges 1 are two semicircular objects which are respectively arranged at the top end of the left side of the bite block, are vertical to the upper part and the lower part of the bite block and are smooth in edge; the flange 1 is arranged outside the lips of the patient and used for fixing the lips; the bite block 2 is a hollow elliptic cylinder with a left connecting flange 1, a right connecting jaw internal fixator 3 and a pharyngeal bend 4; the tooth pad 2 is arranged in the middle of teeth, so that the teeth are occluded due to the contraction of facial muscles of a person in a coma state, and the tooth pad 2 is fixed; meanwhile, the bite block 2 can also prevent biting the tongue; the jaw internal fixator 3 is two semicircular objects which are respectively arranged at the connection point of the bite block 2 and the pharyngeal bend 4, are vertical to the bite block 2 and have smooth edges, and the semicircular objects below the bite block 2 are relatively small so as to adapt to the oral cavity structure of a human body; the jaw internal fixator 3 is arranged in the oral cavity of a patient; when a person is in a coma, the upper jaw and the lower jaw are closed due to the contraction of facial muscles, so that the fixing function on the jaw internal fixator 3 is realized; the pharyngeal bend 4 is an arc-shaped tube which is connected to the right side of the bite block and has smooth edge; is arranged in the oral cavity of a patient, and the inward bend of the tongue fixes the tongue in the lower jaw to prevent the tongue from biting and falling backwards.

The utility model discloses a theory of operation: fully utilizes the physiological characteristics of the human body, and can close the upper jaw and the lower jaw to bite the occlusal joint when the human body is in an anesthesia or coma state; patient's lip is fixed the edge of a wing 1 in the oral cavity outside, and tooth interlock bite-block 2, and internal fixation ware 3 in the jaw is carried to upper and lower jaw, thereby it is right the utility model provides a pair of oropharynx air duct plays good fixed action to make the crooked 4 stable fixed tongues of pharynx, prevent to appear stinging the unexpected emergence such as tongue and tongue tenesmus initiation machinery stifling.

As an example, the purpose of the device is; can be fixed at the mouth and the pharynx of a person without harm; the defect that the traditional single-flange oropharynx air duct needs to be fixed externally is overcome, and the defects of easy allergy, easy falling and the like are overcome; simplify the clinical operation steps.
