Problems solved by technology

With the different ages and body shapes of patients, the shape and length of the required oropharyngeal airway are also different. In the prior art, the airway is set as a fixed bend in order to meet the needs of different people as much as possible. However, setting the ventilation tube in a fixed curved shape makes it difficult for the oropharyngeal airway to better match the needs of patients of various sizes, which affects the comfort of patients

Embodiment 1

[0039] This embodiment relates to a kind of oropharyngeal airway, refer to figure 1 As shown, the oropharyngeal airway includes a flange plate 1, and also includes a vent tube 2 that is fixedly connected with the flange plate 1 and can extend into the patient’s oral cavity, and the vent tube 2 is set to follow the shape of the patient’s tongue. Curved and shaped to fit the patient's tongue.

[0040] In the oropharyngeal airway of this embodiment, the ventilation tube 2 can be bent and shaped according to the shape of the patient's tongue. The ventilation tube 2 can better fit the patient's tongue, thereby improving the patient's comfort and tolerance. The comfort is specifically, for example, reducing the foreign body sensation in the patient's oral cavity, making it easier for the patient to swallow, and the like.

[0041] A preferred structure of the oropharyngeal airway is as figure 1 As shown, the above-mentioned flange plate 1 is in the shape of a square plate. When in...

Embodiment 2

[0059] This embodiment relates to an oropharyngeal airway, and the oropharyngeal airway has approximately the same structure as the oropharyngeal airway in Embodiment 1. The difference lies in: in this embodiment, the support layer 221 of the ventilation tube 2 It includes a number of support tubes 5 connected in series, and the two adjacent support tubes 5 are hingedly connected so that the two adjacent support tubes 5 can rotate with each other to form the bending of the ventilation tube 2; A damping assembly is provided between two adjacent support tubes 5 for shaping the vent tube 2 .

[0060] For specific structure, refer to Image 6 with Figure 7 As shown, the cross-section of each section of support tube 5 is square, and two first ear plates 51 arranged oppositely are configured on the end face of each support tube 5, and the two first ear plates 51 are set as concave On the outer wall of the support tube 5 , hinge holes 501 are opened on the two first ear plates 51 ...

Embodiment 3

[0063] This embodiment relates to an oropharyngeal airway, which has approximately the same structure as the oropharyngeal airway described in Embodiment 1 or Embodiment 2. The difference lies in: in this embodiment, the plug-in The unit includes symmetrical insertion holes 201 opened on two opposite side walls of the ventilation pipe 2, and the insertion holes 201 on each side are arranged at intervals along the length direction of the ventilation pipe 2; The two inserting rods 6 on the edge plate 1, and the first elastic members 61 respectively connected with the two inserting rods 6, the two inserting rods 6 are driven by the first elastic members 61 and can be inserted into the two inserting rods correspondingly. In the connection hole 201; the plug-in unit also includes a driving rod 7 that is drivingly connected to the two plug-in rods 6, and a second elastic member 62 connected to the driving rod 7; the driving rod 7 can be driven by an external force to compress the sec...

Abstract

The invention provides an oropharyngeal airway. The oropharyngeal airway comprises a flange plate and further comprises a breather pipe which is fixedly connected with the flange plate and can extendinto an oral cavity of a patient, and the breather pipe is arranged to be capable of being bent and shaped according to the shape of the tongue of the patient so as to be attached to the tongue of thepatient. The oropharyngeal airway can effectively improve the comfort of the patient.

Description

technical field [0001] The invention relates to the technical field of oropharyngeal medical devices, in particular to an oropharyngeal airway. Background technique [0002] The oropharyngeal airway is used for patients with complete or partial upper airway obstruction after induction of anesthesia or unconscious patients who need dental pads. It can effectively improve ventilation, prevent patients from trismus, and improve rescue efficiency. Among them, the oropharyngeal airway mainly includes a flange plate and a ventilation tube fixed on the flange plate. The flange plate is used to block the outside of the patient’s lips to prevent the patient from swallowing the ventilation tube; the ventilation tube extends into the patient’s oral cavity. Inside, used to assist patient ventilation. With the different ages and body shapes of patients, the shape and length of the required oropharyngeal airway are also different. In the prior art, the airway is set as a fixed bend in or...
