Problems solved by technology

[0004] The air circuit of the existing common ventilator is complex, and the machine is large in size, which is not easy to move and carry
In addition, since the gas is delivered to the pipeline through the fan, and the gas needs to be pressurized, the noise will also increase accordingly.

Embodiment Construction

[0021] In order to make the principles, characteristics and advantages of the present invention clearer, the following description will be made in conjunction with specific embodiments and with reference to the accompanying drawings.

[0022] refer to figure 2 , a portable ventilator provided by an embodiment of the present invention includes a casing 10 , a fan 20 , an air outlet pipe 30 and a control circuit board 40 .

[0023] Wherein the fan 20 has a built-in micro motor 21, and the fan 20 is connected with the outlet pipe 30 for delivering gas to the outlet pipe;

[0024] Because it is a portable device, the volume of the ventilator is relatively small, so a micro motor is used.

[0025] In a specific embodiment, since a relatively large air pressure is generated during use, the micromotor needs to run at a high speed, so the micromotor adopts a motor with an air dynamic pressure bearing, and the noise is small when it is running at a high speed, so that the user (patie...

Abstract

The invention discloses a portable respirator comprising a housing, a blower fan, an air outlet pipe and a control circuit board; the blower fan is connected with the air outlet pipe so as to convey air to the air outlet pipe; an air pressure and flow rate monitoring device is arranged in the housing; the air outlet pipe outlet is provided with an airway, and connected with the air pressure and flow rate monitoring device, thus detecting output air pressure and flow rate; the air pressure and flow rate monitoring device is connected with the control circuit board, and used for sending obtained electric signals to the control circuit board; the control circuit board can adjust the output air flow rate and air pressure according to the received signal. The portable respirator employs a more compact internal structure and miniature parts, and the airway components are simple, thus obvious reducing the equipment volume; the portable respirator is easy to move, easy to carry, and more economical and suitable; in addition, various damping and noise reduction measures are carried out, thus effectively controlling respirator working noises.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a portable ventilator. Background technique [0002] Non-invasive ventilation therapy includes continuous positive airway pressure (CPAP, Continuous Positive Airway Pressure), bilevel positive airway pressure (BiPAP, Bilevel Positive Airway Pressure) and automatic positive airway pressure (APAP, Automatic Positive Airway Pressure). Among them, CPAP is the most commonly used. The basic principle is to give a certain positive pressure to the upper airway from beginning to end through a nasal mask or an oral and nasal mask throughout the process of exhalation and inhalation, so that it remains open and does not collapse. Apnea and hypopnea due to airway collapse are thereby avoided. Non-invasive ventilation therapy can achieve very satisfactory results as long as the patient can tolerate it and the pressure is appropriate, and can eliminate snoring, shortness of breath an...
