Cardiopulmonary resuscitation machine with high frequency ventilation function

Abstract

The invention discloses a cardiopulmonary resuscitator with high-frequency ventilation function, which comprises a plate-shaped base plate, a column arranged on the side of the plate-shaped base plate, a chest compressor arranged on the column, and a chest compressor installed on the top of the column or the plate-shaped base plate. It also includes high-frequency ventilation solenoid valve and high-frequency ventilation air source interface. The high-frequency ventilation solenoid valve is installed in the controller housing, and the high-frequency ventilation air source interface is installed on the controller housing; The air outlet of the high-frequency ventilation solenoid valve is connected to the high-frequency ventilation air source interface through a pipeline; the high-frequency ventilation solenoid valve is electrically connected to the press ventilation controller in the controller housing. The advantages are: the open high-frequency ventilation function is added on the basis of the traditional cardiopulmonary resuscitation machine; the two functions of intermittent positive pressure ventilation and open high-frequency ventilation can be switched on one cardiopulmonary resuscitation machine at the same time, which expands the scope of use and is suitable for Rescue of various respiratory failure and emergency suffocation patients.

Description

[0001] Technical field: [0002] The invention relates to a medical device, in particular to a cardiopulmonary resuscitator with high-frequency ventilation function. [0003] Background technique: [0004] Traditional cardiopulmonary resuscitation machines use intermittent positive pressure ventilation and chest compressions to perform cardiopulmonary resuscitation alternately at a certain ratio. The disadvantage is that intermittent positive pressure ventilation is closed ventilation and cannot be used for patients with open airways. Rescue; intermittent positive pressure ventilation will increase the airway and lung pressure, easily cause airway damage, cause a pressurization effect in the lungs, cause the alveoli to open and close repeatedly, generate shear force, and cause alveolar atrophy and inhalation at the end of expiration Excessive expansion of the terminal alveoli, causing lung tissue damage; increased lung pressure will cause increased thoracic pressure, resulting ...

Problems solved by technology

[0004] Traditional cardiopulmonary resuscitation machines use intermittent positive pressure ventilation and chest compressions to perform cardiopulmonary resuscitation alternately at a certain ratio. The disadvantage is that intermittent positive pressure ventilation is closed ventilation and cannot be used for patients with open airways. Rescue; intermittent positive pressure ventilation will increase the airway and lung pressure, easily cause airway damage, cause a pressurization effect in the lungs, cause the alveoli to open and close repeatedly, generate shear force, and cause alveolar atrophy and inhalation at the end of expiration Excessive expansion of the terminal alveoli, causing lung tissue damage; increased lung pressure will cause increased thoracic pressure, resulting in reduced thoracic venous return, which is not conducive to the rescue of critically ill patients with respiratory failure accompanied by hypovolemia and circulatory insufficiency; in the rescue of cardiopulmonary resuscitation During the process, when the patient resumes spontaneous breathing, the intermittent positive pressure ventilation cannot be synchronized with the patient's spontaneous breathing, resulting in man-machine confrontation; When the airway is not smooth, it is necessary to stop intermittent positive pressure ventilation and perform airway suction, which may easily cause hypoxemia in patients; the above-mentioned shortcomings cause the traditional cardiopulmonary resuscitation machine to have a single function and limited use
