Background

Clinically, oxygen therapy is often used for critically ill patients who cannot breathe spontaneously. Because such patients are unable to breathe spontaneously, there are two clinical ways to promote patient respiration: firstly, invasive intubation is carried out on a patient, and oxygen is directly conveyed to a respiratory tract; and secondly, the oxygen mask is worn without intubation, oxygen is noninvasively conveyed to the respiratory tract of the patient, but the respiratory autonomous ability of the critically ill patient is weak, the normal flow of oxygen cannot meet the respiratory demand of the patient, the oxygen needs to be pressurized, and the oxygen is provided for the patient after the oxygen flow is increased. Clinically, there is adjustable oxygen flow respirator who comes into operation, however, this type of respirator purchase expense is high, and the popularization degree is low, and the ward of many hospitals does not also possess the ability of equipping with high flow respirator, can't satisfy patient's user demand. The high-flow respirator circulating in the existing market has high interface specificity, and needs to be connected with a matched pipeline produced by an original manufacturer for use, so that the cost of the pipeline is high, and the medical burden of a patient is increased.

The utility model discloses a but automatic pressure boost and adjustable gas flow's oxygen bag (CN201720113238.4) disclose following technical scheme: the oxygen bag, include dustcoat, spring, holding down plate, oxygen bag, gas outlet, can regulate and control the valve, give vent to anger the pipe four angles that the last demonstration of dustcoat are installed respectively the spring the lower extreme of spring is connected with the holding down plate, the below of holding down plate is equipped with the oxygen bag, the oxygen bag is located inside the dustcoat the below of oxygen bag is equipped with the gas outlet, the end of giving vent to anger of gas outlet with can regulate and control the one end of valve and connect, the other end of valve with give vent to anger the pipe connection. The utility model can automatically pressurize, i.e. the oxygen in the bag is difficult to be automatically output without needing manpower to extrude; the output volume of oxygen can be regulated and control, oxygen output volume can be adjusted according to the patient condition, has avoided patient too much or the problem of too little suction pure oxygen, has reduced the probability of medical hidden danger, the utility model has the advantages of labour saving and time saving, safety, convenient. However, the oxygen bag is not suitable for patients who are continuously clinically administered oxygen.

Aiming at the problems existing in the prior art: firstly, the existing supercharging respirator has high use cost and cannot be popularized and used; secondly, the oxygen delivery pipe on the existing respirator is too long, which affects the emergency treatment effect on the patient, and the joints of the delivery pipe cannot be matched with the joints of all the respirators; the existing oxygen delivery pipes are all reused, which may cause disease infection among patients and need to be disinfected regularly. The utility model provides an oxygen therapy device for critically ill patients, the oxygen therapy device can
