Description
Technical Field
The invention relates to a medical apparatus, in particular to a multifunctional pressurizing jaw support.
Background
It is well known that in conventional anesthesia clinics, emergency rooms, intensive care units, clinicians are often faced with under-jaw and pressure assisted ventilation, such as: 1. during the anesthesia induction period, when the drugs with respiratory depression and upper respiratory tract obstruction completely play a role, spontaneous breathing of the patient completely disappears, and in the process, an anesthesiologist needs to hold the lower jaw of the patient, so that the respiratory tract is ensured to be unobstructed and mask pressurization assisted ventilation is performed. The anesthesiologist can complete the process of pressurizing and supporting the lower jaw by the mask in the anesthesia induction period about three minutes through supporting the lower jaw by one hand and supporting the lower jaw by two hands. If the head and the face of the patient are too large, another anesthesia nurse is needed to carry out air sac assisted ventilation when the anesthesia doctor holds the lower jaw with both hands, or mechanical ventilation is carried out when the anesthesia doctor holds the lower jaw with both hands so as to ensure sufficient oxygen supply and ventilation. 2. In the recovery period of anesthesia tube drawing, respiratory depression and upper respiratory tract obstruction are easy to occur to patients due to residual actions of anesthetics and muscle relaxants, anesthetists need to hold the lower jaw of the patients to ensure the upper respiratory tract to be smooth, and even a mask is needed to pressurize and assist ventilation to ensure oxygen supply and sufficient ventilation. 3. Under the condition of keeping spontaneous breathing general anesthesia, when the operation stimulus and the anesthesia depth are not matched and the anesthesia depth is relatively too deep, respiratory depression occurs to a patient, and an anesthesiologist is required to carry out transitional mandible support, mask pressurization auxiliary ventilation or mask pressurization mechanical ventilation. 4. In emergency and intensive care units, patients mechanically ventilated using a ventilator are prone to cases of conscious or unconscious partial respiratory depression, upper respiratory obstruction, anxiety due to intolerance, accidental tube drawing, etc. during the period of ventilator withdrawal, due to illness state, sedative analgesic use, residual muscle relaxation effect, etc., and then re-intubation and under-jaw pressurization assisted ventilation may need to be performed after evaluation. 5. In pre-hospital and intra-hospital rescue, such as respiratory cardiac arrest, coma, poisoning, seizures, cerebral apoplexy, and the like, patients may have respiratory depression, upper respiratory tract obstruction, high muscular tension, and the like, artificial auxiliary ventilation is laborious, and an operator is easy to feel tired of hands and arms, and needs to replace the operator to continue mask pressurization auxiliary ventilation.
In all of the above clinical scenarios, the clinician is required to perform pressure assisted ventilation or mechanical assisted ventilation of the mandibular or mandibular mask for several minutes or even tens of minutes. However, no mandibular support capable of replacing the doctor to perform mask pressurization ventilation in the above-mentioned situations exists in the market at present.
