Portable universal life support system for field emergency treatment

Abstract

The invention discloses a portable universal life support system for field emergency treatment. The portable universal life support system comprises a life support system host which is quickly positioned on a stretcher through a stretcher fixing device, wherein the life support system host comprises a host shell and an infusion device; a host main bracket is fixedly arranged inside the host shell; a mechanical ventilation module and a breathing module are positioned inside the host main bracket; the mechanical ventilation module is used for providing mixed oxygen for a patient and can avoid the situation that gas exhaled by the patient cannot be discharged; the breathing module is communicated with the mechanical ventilation module, is used for performing breathing treatment on the patient and can ensure that the patient inhales autonomously; a power supply module for supplying power to the whole device is arranged inside the host main bracket; and a system control module is arranged above the host main bracket. According to the portable universal life support system disclosed by the invention, infusion treatment and breathing treatment on the patient can be realized, the patient can be continuously and normally subjected to breathing treatment, and normal breathing of the patient is not influenced even if the device fails.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more particularly to a portable universal life support system for field emergency treatment. Background technique [0002] In modern clinical medicine, ventilator, as an effective means to artificially replace the function of spontaneous ventilation, has been widely used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. [0003] A ventilator is a breathing 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 air sourc...

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 gas exhaled by the patient cannot be discharged due to the single expiratory channel, which will affect the personal safety of the patient.

[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 alpine environment will supply the patient with damp and cold air for breathing, which will cause 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 host 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 rapid first aid in the field

[0012] 6) During the field transportation, the vibration of the breathing module causes the control of the turbine speed to be unstable, which further leads to the instability of the flow rate or pressure of the mechanical ventilation, which may reduce the comfort of the patient when 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
