Abstract

The invention relates to a medical instrument, particularly provides oxygen-supply resuscitation respiratory equipment, and aims at solving the problems that an existing oxygen inhaling device cannot achieve a smooth transition from the inhaling process to the exhaling process, and too much noise exists. For this purpose, the respiratory equipment comprises a needle valve assembly arranged between a main oxygen inhaling channel and an inner cavity, the needle valve assembly comprises a needle valve fixing seat, a needle valve sleeve which is embedded in the needle valve fixing seat in a sleeved mode, a needle valve matched in the needle valve sleeve in a sliding mode, a needle valve sealing ring which is embedded in the needle valve sleeve in a sealed and sleeved mode and a needle valve spring which is arranged between the top end of the needle valve sleeve and the top end of the needle valve, and multiple air inlets are formed in the needle valve sleeve. In the non-operating state, a piston valve abuts against the top end of the needle valve under the action of a piston valve spring and compresses the needle valve spring, and therefore the needle valve sleeve does not make contact with the needle valve sealing ring. Accordingly, by means of the needle valve, the smooth transition from the inhaling process to the exhaling process can be achieved, and the noise problem related to the prior art is eliminated.

Description

technical field [0001] The invention relates to a medical device, and specifically provides an oxygen supply resuscitation breathing device. 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 device that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] CN1069891A discloses a resuscitating oxygen inhalation device. The oxygen inhalation device is provided with a main oxygen inhalation channel and an auxiliary oxygen inhalation channel, which can not only realize the pure oxygen inhalation function, but also realize the oxy...
