  • Conventional technology having an oxygen concentration controllable device having an expiratory inspiratory valve complex and a storage tube for use in a spontaneously breathing patient using a tracheal tube or a mask.
  • oxygen is supplied to a spontaneously breathing patient using a tracheal tube by inserting an oxygen supply catheter into the tracheal tube or placing a mask or similar object over the tracheal tube opening and supplying oxygen to it.
  • the tube was connected.
  • an oxygen supply tube was connected directly to the mask.
  • Nasal catheterization was common in patients who did not use them.
  • the amount of oxygen delivered to the patient is less than or equal to the amount of oxygen that flowed during the inspiratory phase and the amount of oxygen that flowed during other times. The element is not used and is wasted.
  • re-inhale a portion of the breath in patients with masks, re-inhale a portion of the breath.
  • the amount of oxygen actually supplied to the patient was significantly lower than that indicated by the oxygen flow meter, and the oxygen concentration in the inspired air could not be adjusted, making it particularly difficult to inhale high oxygen concentrations.
  • Some oxygen inhalers use the bench lily effect, but a high flow rate of oxygen is required to increase the oxygen concentration in the intake air.
  • the oxygen concentration in the intake air can be adjusted appropriately from 21% to 100% with a relatively low flow rate of constantly flowing oxygen. It is economical to supply oxygen to patients without waste. There is almost no respiratory resistance. Light and small device, structure Is simple, can be mass-produced at low cost, and can be disposable. The usage is simple. Does not re-inhale expiration. Even if the tube comes off or the oxygen supply is stopped, the air supply is guaranteed and it is extremely safe. There is no device that satisfies all of these characteristics. Structure and function of the oxygen supply device of the present invention
  • the oxygenator places an exhalation-inspiratory valve complex at the patient's end (proximal end), where exhalation is expelled directly to the outside via a flow valve (expiratory valve).
  • the inspired air enters through another one-way valve (inspiratory valve) and is supplied to the patient.
  • the inspired air is the one in which the oxygen concentration is set in the respiratory tract, that is, the oxygen and the atmosphere are separated at a specified ratio on both the proximal and distal sides, and are mixed after being inhaled.
  • Oxygen concentration setting is adjusted by adjusting the flow rate from the oxygen supply source.
  • a smaller-diameter oxygen supply tube is installed inside the storage tube, and its opening is located near the intake valve.
  • the patient's opposite end (distal end) of the respiratory tract is released and fills the respiratory tract, and any excess oxygen is released into the atmosphere without resistance.

Abstract

Un dispositif d'alimentation en oxygène fournit de l'oxygène en concentration optimale à un patient, sans perte, il élimine l'aspiration de l'expiration et offre peu de résistance à la respiration, et il peut ajuster avec précision une concentration d'oxygène d'inspiration entre 21 et 100 % avec de l'oxygène d'un débit relativement faible. Une valve d'expiration et d'inspiration combinées est disposée sur une extrémité (extrémité proximale) du dispositif d'alimentation en oxygène du côté du patient, de sorte que l'expiration puisse être évacuée à l'extérieur par une valve anti-reflux (valve d'expiration), et un tube d'alimentation en oxygène de petit diamètre présentant une ouverture près d'une valve d'inspiration dans un tube de stockage de gaz, dont une extrémité (extrémité distale) située à l'opposé du patient est ouverte, est prévu de manière à faire s'écouler de l'oxygène provenant du tube, ainsi qu'un gaz présentant un rapport oxygène/air défini par un gaz se trouvant dans le tube de stockage de gaz, à travers une valve anti-reflux (valve d'inspiration).
