Suction type anesthesia tube with function of assisting oral cavity expansion

Abstract

The invention relates to the technical field of inhalation type anesthesia tubes, and discloses an inhalation type anesthesia tube with an oral cavity expansion assisting function, which comprises a breathing mask and an oxygen delivery tube, and a breathing follow-up oral cavity expansion mechanism is arranged in the breathing mask; the breathing follow-up oral cavity expansion mechanism comprises a first supporting block, a second supporting block, a first box body, a transverse plate, an air bag, a shielding plate, an air supply pipe and an exhaust hole, after a patient is anesthetized, air exhaled by the patient enters the first box body to enable the air bag to deform, deformation generated in the horizontal direction of the air bag pushes a connecting rod to move rightwards, and the connecting rod is separated from the transverse plate; when a patient exhales, gas entering the first box body is directly shot out of a breathing mask through an exhaust hole, a connecting rod moves rightwards to push a first supporting block on a first pushing rod to rotate, the first supporting block and a second supporting block are relatively away from the upper jaw and the lower jaw of the patient, and the phenomenon is avoided that the patient is damaged in the long-time operation process, the oral cavity is always in a closed state, so that the upper lip and the lower lip are bonded.

Description

technical field [0001] The invention relates to the technical field of inhalation anesthesia tubes, in particular to an inhalation anesthesia tube with the function of assisting oral cavity expansion. Background technique [0002] Inhalation anesthesia is to mix anesthesia gas and oxygen together, introduce the mixed gas into the nasal cavity of the patient through the anesthesia tube, and the patient enters the anesthesia state by inhaling the air containing the anesthesia gas. On the patient's face, keep the mask close to the patient's face. During the operation, the patient is deeply anesthetized and remains under anesthesia. The patient's mouth is always closed. Due to the lack of support for the patient's mouth in the existing breathing mask, after one end After a long period of surgery, the upper and lower lips of the patient are glued together. During the postoperative recovery recovery stage, when the patient opens his mouth for the first time, the glued upper and lo...

[0002] Inhalation anesthesia is to mix anesthesia gas and oxygen together, introduce the mixed gas into the nasal cavity of the patient through the anesthesia tube, and the patient enters the anesthesia state by inhaling the air containing the anesthesia gas. On the patient's face, keep the mask close to the patient's face. During the operation, the patient is deeply anesthetized and remains under anesthesia. The patient's mouth is always closed. Due to the lack of support for the patient's mouth in the existing breathing mask, after one end After a long period of surgery, the upper and lower lips of the patient are glued together. During the postoperative recovery recovery stage, when the patient opens his mouth for the first time, the glued upper and lower lips will cause the epidermis of the lip to tear , increase the postoperative pain of patients, therefore, it is urgent to propose an inhalation anesthesia tube with the common function of mouth expansion
