specific Embodiment approach 1

[0027] Combine below figure 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10 In order to solve the above-mentioned technical problems, a kind of portable automatic respirator for emergency department, including box body 1, mask and valve device 2, airbag end valve device 3, through The box body 1 is equipped with other devices, the mask and the valve device 2 to control the discharge of the patient's exhaled gas and to control the pressure in the valve within a certain range to prevent the patient from breathing poorly due to the opposite direction of the pressure and the breathing direction during oxygen supply. The device 3 realizes the airflow control at the oxygen supply end and prevents the pressure in the airbag from being too high. The automatic oxygen supply adjustment device 4 adjusts the oxygen supply and the change curve of the oxygen supply according to the patients in different states, so as to realize the function of automatic oxygen supply to assist the patient's breathing. The ...

specific Embodiment approach 3

[0030] Combine below figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, and 10 illustrate this embodiment, and this embodiment will further describe Embodiment 1. The described mask and valve device 2 include a mask 2-1, a mask end valve body 2 -2, exhalation valve ball 2-3, exhalation valve spring 2-4, pressure safety valve 2-5, air intake valve 2-6, breathing pipe connector 1 2-7, mask end valve body 2-2 by three The exhalation valve ball 2-3 controls the discharge of exhaust gas exhaled by the patient, the intake valve 2-6 controls the oxygen in the breathing tube 3-1 to smoothly enter the mask 2-1 and supply it to the patient, and the pressure safety valve 2 -5 has a certain preload like the oxygen storage safety valve 3-8. When the oxygen introduced by the breathing tube 3-1 and the exhaust gas exhaled by the patient are carried out simultaneously, the internal pressure of the valve body 2-2 at the mask end will increase. And the patient's breathing is not smooth, at this time, the pr...

specific Embodiment approach 4

[0032] Combine below figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, and 10 illustrate this embodiment, and this embodiment will further illustrate Embodiment 1. The air bag end valve device 3 includes a breathing tube 3-1, a breathing tube connector 2 3-2, air bag end valve body 3-3, oxygen tank connector 3-4, oxygen storage inlet valve 3-5, air outlet valve 3-6, air bag 3-7, oxygen storage safety valve 3-8, oxygen storage safety valve The valve spring 3-9, due to the initial adjustment, completes the extrusion of the airbag 3-7 to different degrees, so that oxygen is pushed out from the airbag 3-7. At this time, the valve body 3-3 at the end of the airbag is composed of three sets of one-way valve bodies. The air outlet valve 3-6 controls the oxygen entering the breathing tube 3-1, the oxygen storage inlet valve 3-5 controls the positive pressure of the oxygen in the oxygen tank to enter the air bag 3-7, and the oxygen storage safety valve 3-8 passes through the oxygen storage with a c...

Abstract

A portable automatic respirator for the emergency department comprises a box body, a mask and valve device, an air bag end valve device and an automatic oxygen supply regulating device; other devices are installed through the box body; the mask and the valve device are used for controlling exhaust of exhaled air of a patient and controlling pressure intensity in the valve to be within a certain range to prevent poor breath of the patient due to the fact that the pressure intensity direction is opposite to the breath direction during oxygen suppl; the air bag end valve device achieves oxygen supply end air flow control and prevents the pressure intensity in an air bag from being too high; and the automatic oxygen supply regulating device is used for regulating the oxygen supply amount and the oxygen supply change curve according to patients in different states to achieve the function of automatically supplying oxygen to assist the patients in breathing. The portable automatic respirator is characterized in that the mask and the valve device are fixedly installed on the air bag end valve device, the air bag end valve device is fixedly installed on the box body, and the automatic oxygen supply regulating device is fixedly arranged on the box body.

Description

technical field [0001] The invention relates to a medical device, in particular to a portable automatic respirator used in an emergency department. Background technique [0002] With the development of science and technology, more and more high-end equipment has been introduced into our life and work. In the emergency department of the medical industry, it is usually necessary to provide oxygen to patients with weak breathing and difficulty breathing. Assist patients so that they can gradually maintain a normal breathing state with the assistance of equipment. The current level of intelligence and automation of simple ventilators on the market is not high, and when treating patients with different breathing intensities, medical staff need to judge their breathing conditions based on experience. Oxygen is supplied manually after the amount of oxygen supply is required, and the large ventilator has a complicated structure and cannot adapt to some special situations. Therefore,...
