A portable universal life support system for field emergency rescue

Abstract

The invention discloses a portable universal life support system for field emergency treatment, which comprises a life support system host quickly positioned on the stretcher through a stretcher fixing device, the life support system host includes a host shell and an infusion device; the inside of the host shell is fixed The host main frame is provided with a mechanical ventilation module for providing mixed oxygen for the patient and avoiding the situation that the patient’s exhaled gas cannot be discharged, and is connected with the mechanical ventilation module for respiratory treatment of the patient and can be positioned inside the main frame of the host computer. A breathing module to ensure the patient's self-inhalation, a power supply module for powering the device as a whole is installed inside the main frame of the host, and a system control module is installed above the main frame of the host. The invention can realize the transfusion therapy and respiratory therapy for the patient, and can ensure that the patient continues to perform the respiratory therapy normally, even if the device breaks down, the normal breathing of the patient will not be affected.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically relates to a portable universal life support system for field emergency rescue. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] The ventilator is a respiratory device designed for artificial mechanical ventilation for patients who need to provide respiratory support, respiratory therapy and emergency resuscitation. It usually uses a high-pressure...

AI Technical Summary

Problems solved by technology

[0006] 1) Dual-tube and electromechanical ventilation modules that support invasive ventilation usually include modules such as large-diameter inspiratory valves and safety valves, which are complex and increase weight, volume, and cost. Disadvantageous for small and lightweight portable general life support systems

Moreover, if the valve on the mechanical ventilation module is blocked, the patient's exhaled gas cannot be discharged due to the single exhalation channel, which will affect the patient's personal safety.

[0007] 2) The traditional breathing module only delivers the oxygen stored in the box to the patient through the oxygen tube and the breathing mask; however, when the power supply of the breathing module is interrupted or the breathing module fails, the patient cannot obtain oxygen through the portable life support system, and During this process, since the breathing mask is tightly fastened to the patient's face, the patient will not be able to inhale spontaneously in the event of a shortage of oxygen delivery, which poses a major safety hazard

[0008] 3) The current life support system usually does not have the infusion function, and the function is single

The air mixer in the prior art usually does not have the function of heating the mixed gas, and the ventilator in the high cold environment supplies the air for the patient to breathe because of this, causing discomfort to the patient

Moreover, the air and oxygen mixing method of the current air mixer is that the turbine extracts the gas in the oxygen mixing chamber, and the gas flows in the chamber for mixing. The mixing time is short, the degree of mixing is not sufficient, and the mixing efficiency is not high.

[0011] 5) At present, there is no fixing device on the market that can quickly disassemble and assemble the main unit and the stretcher. The fixing device is also relatively bulky and prone to fall off, which delays the time for first aid to patients and cannot be applied to quick first aid in the field

[0012] 6) During the field transportation, there is a situation where the breathing module bumps lead to unstable control of the turbine speed, which further leads to unstable mechanical ventilation flow rate or pressure, which may reduce the comfort of patients using mechanical ventilation, and may even reduce the impact of mechanical ventilation. Patient Outcome

[0013] 7) The current life support system has a complex structure, takes up a lot of space, and the product is heavy, which is not conducive to handling
