Automatically-adjustable oxygen inhaling device

Abstract

The invention discloses an automatically-adjustable oxygen inhaling device. The automatically-adjustable oxygen inhaling device comprises a base, an oxygen control mechanism, a humidification mechanism, a finger-clip-type oximeter and a breathing mask. A respiratory rate sensor is arranged on the breathing mask. The oxygen control mechanism comprises a control bottle mounted on the base. A first oxygen inlet and an oxygen discharge adjusting port are arranged on the control bottle. A rectangular box covering the oxygen discharge adjusting port is fixed to the outer side of the control bottle.A first oxygen outlet is arranged at the upper end of the rectangular box. A piston, a threaded tube, a stepping motor and a screw are arranged in the control bottle. The screw rotates to drive the threaded tube and the piston to move in a control tube. The humidification mechanism comprises a humidification box, an ultrasonic atomizer, a temperature and humidity sensor and a heater. A second oxygen inlet, a second oxygen outlet, a water adding inlet and a water discharge outlet are arranged on the humidification box. Distilled water is stored in the humidification box. The automatically-adjustable oxygen inhaling device has the advantages of simple structure and high practicably.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatically adjustable oxygen inhalation device. Background technique [0002] Oxygen infusion is a commonly used clinical nursing technique and rescue treatment. The relative humidity of the currently used medical oxygen is only about 3% when it is connected to the terminal. Direct inhalation will cause serious damage to the respiratory tract. Therefore, it must be humidified before entering the human body to avoid dry oxygen from irritating the respiratory mucosa. , improve oxygen therapy effect and patient comfort. The oxygen inhalation device can continuously provide oxygen for the patient. The existing oxygen input method is to directly connect the oxygen to the patient's mouth and nose, but the existing oxygen inhalation device cannot automatically adjust the oxygen supply. When the blood oxygen concentration of the patient reaches saturation Oxygen supply ne...

Problems solved by technology

The relative humidity of the currently used medical oxygen is only about 3% when it is connected to the terminal. Direct inhalation will cause serious damage to the respiratory tract. Therefore, it must be humidified before entering the human body to avoid dry oxygen from irritating the respiratory mucosa. , improve oxygen therapy effect and patient comfort

The oxygen inhalation device can continuously provide oxygen for the patient. The existing oxygen input method is to directly connect the oxygen to the patient's mouth and nose, but the existing oxygen inhalation device cannot automatically adjust the oxygen supply. When the blood oxygen concentration of the patient reaches saturation Oxygen supply needs to be continued, and the oxygen does not stop. Only when the nurse cuts off the oxygen flow will it be terminated. This method cannot deliver oxygen in real time according to the actual condition of the patient's body, which will lead to excessive delivery and waste of oxygen, and increase the workload of medical staff.
