Problems solved by technology

The inventor's previous Chinese patent 011209097.2 (disclosure date on February 13, 2002) discloses a kind of oxygen-spraying anesthesia laryngoscope with manual function. This patent improves the existing anesthesia laryngoscope, adding A device for manually spraying oxygen and medicine is developed, the purpose of which is to supply oxygen to the body through manual jet ventilation and to spray cardiopulmonary resuscitation drugs into the body during endotracheal intubation; however, the laryngoscope has problems in use The disadvantage is that a siphon phenomenon occurs in the liquid medicine pipe immediately after oxygen spraying. At this time, the manual valve designed on the throat handle can only close the oxygen but not the liquid medicine at the same time, so that the liquid medicine in the liquid medicine cylinder cannot be retained. Less than the purpose of continuous intermittent drug administration; meanwhile, there is also the defect that the gas medicine can not be controlled separately
And there is another kind of anesthesia laryngoscope that uses a two-position two-way valve to control the structure of the liquid medicine alone, but the liquid medicine is easy to produce liquid crystallization in the two-position two-way valve, which limits the sensitivity of the valve body and cannot reach the control of the medicine. In addition, there is another anesthesia laryngoscope that uses a two-position two-way valve to control oxygen alone, but its processing accuracy is difficult to achieve a good sealing effect, and it is not convenient for industrial production
