Automatic respirator

Abstract

The invention discloses an automatic respirator. The automatic respirator comprises an air pump, an expandable air bag, a mask and a control module; an air inlet of the air pump is connected with an air source or an oxygen source at the same time, an air outlet of the air pump is connected to the expandable air bag, and the expandable air bag is connected to the mask through a respiratory tube and is made of an elastic thin-wall material; a pressure control valve is connected between the expandable air bag and the mask, a valve is arranged between the expandable air bag and the air pump, and the pressure control valve is connected to the signal input end of the control module and connected to the valve through the signal output end of the control module. By means of electric operation, the automatic ventilation function is provided, after pressure of the expandable air bag reaches a certain value, the pressure control valve can be triggered to be switched on, and air in the air bag input air to the pressure control valve to achieve the automatic ventilation function of the air bag. Enough tidal volume and needed respiratory rate can be ensured, respiration parameters are made to be precise, the tidal volume and needed respiratory rate can be adjusted, and inconvenient operation during human assistance respiratory is avoided.

Description

technical field [0001] The invention belongs to medical equipment, and specifically designs an automatic respirator used for first aid of patients' pre-hospital breathing. Background technique [0002] When a patient suddenly has apnea, the doctor needs to immediately use the first aid method of assisted breathing. During the hospitalization process, there are large and mature ventilators available, but in the pre-hospital first aid, the simple breathing airbag currently used in clinical Rescue is a very common and useful instrument, which is composed of a spherical airbag connected with a breathing mask. It is light and easy to carry, and is used to provide external tidal volume when spontaneous breathing stops. The disadvantage is that this first aid instrument is manual and requires experienced doctors In order to provide a good rescue for the patient, the left hand needs to hold the breathing mask, and the right hand needs to press the airbag. While rescuing, it is neces...

Problems solved by technology

[0004] The present invention aims at the above-mentioned technical defects existing in the existing air bag respirator, and provides a new type of air bag type automatic respirator, which replaces the previous manual air supply mode or mechanical extrusion air bag mode with automatic air bag air supply, without manual pressing The airbag, the airbag can automatically ventilate to provide the patient with the required tidal volume, relieve the inconvenience and fatigue of the medical staff during the rescue process, and solve the problem that the simple breathing airbag cannot provide accurate quantified tidal volume and frequency. At the connection between the breathing tube and the mask A buckle structure is added to prevent the breathing tube from slipping off from the mask or automatic breathing device during operation
