Description
Technical field
The present invention relates to a kind of high pressure oxygen injector, particularly a kind of high pressure oxygen injector that uses in the oral cavity anaerobium process for the treatment of belongs to technical field of medical instruments.
Background technology
In the patient of oral cavity infection, pathogenic bacterium mostly are anaerobe, and the ecological disturbance that is host and periodontal microorganism causes, and are that the main anaerobe that turns to gradually is main dysbacteriosis process comprising aerobe is arranged.Given this, widely apply anti-anaerobic agents such as metronidazole, tinidazole to become routine (local application or systemic administration) in the treatment of oral cavity infection, but along with the application of metronidazole in dental care is increasingly extensive, its toxic and side effects has discovery also the time.Related data shows that the hyperbaric oxygen condition has more application to explore, and has shown the curative effect that it is unique in clinical.To the oral cavity treatment of diseases, clinical research was done in the application of hyperbaric oxygen condition also someone, and demonstrated excellent curative.
When adopting traditional mask oxygen-inspiration, the periodontal pocket bag mouth is less, HBO arrives the amount at the dark bag bag end less than shallow bag, and the dark bag of the oxygen amount that arrives shallow bag increases, the inhibitory action that anaerobe and spirillum in the shallow bag are grown strengthens, and bacillus, shuttle shape bacterium and spirillum quantity reduce in the shallow bag, to the therapeutical effect enhancing of shallow bag periodontitis, and relatively poor for dark bag curative effect, use and limited to.And, the hyperbaric oxygentherapy of mask oxygen-inspiration formula also can cause a series of complication, be many wherein with the middle ear dysbarism, show as earplug, bulge of the ear, otalgia, middle otorrhagia and tympanum hematoma etc., though general favourable prognosis, do not cause sequela, but the patient need do the bulging cheek, action such as swallow, bring inconvenience to treatment.
Publication number is the Chinese patent of CN1923306, discloses a kind of respiratory tract high pressure oxygen spray drug administration system.Be made of hyperbaric oxygen source of the gas, medical liquid container and spray nozzle, the hyperbaric oxygen source of the gas communicates with medical liquid container by air inlet pipe, and medical liquid container communicates with spray nozzle by playpipe again.Air inlet pipe is provided with the trigger-type pressure switch, can form the instantaneous pressure air-flow, high pressure oxygen with high velocity air by air inlet pipe and medical liquid container, medicinal liquid in the medical liquid container is involved in high velocity air and is ground into droplet not of uniform size, atomize, form gas-liquid mixture with high pressure oxygen, gas-liquid mixture is under the promotion of pressure, enter spray nozzle through playpipe, further atomizing, and in patient's respiratory tract, spray, cooperate patient's deep breathing action to enter the deep of air flue fast, thereby throat and airway surface are carried out sufficient topical anesthesia, thereby reduce patient's misery and treatment time, for improving operation safety and patient satisfaction, reduce doctor-patient dispute and have great importance.But because it uses position is respiratory tract, and administering mode etc. can't satisfy the needs of oral cavity anaerobium treatment.
