Description

[0002] In modern clinical medicine, respiratory equipment, as an effective means of artificially replacing the self-ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. It occupies a very important position in the field of modern medicine. Respiratory equipment is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. During the use of oxygen, in order to ensure the comfort of the patient after inhalation, it is usually humidified, and the existing general humidifier uses oxygen to pass through an oxygen inhaler filled with pure water to increase the humidity of the oxygen.

[0003] Although this method is simple, its effect on oxygen humidification is very limited. Although it can control the size of the ventilation volume, it cannot control the degree of oxygen humidification very well. The mixing uniformity of moisture and oxygen at different stages will be different. Oxygen with lower humidity will have a smaller effect, and oxygen with higher humidity will cause the oxygen concentration to decrease, which will cause the patient to have difficulty breathing and may be accompanied by bacterial growth. In addition, the existing oxygen humidification structure will produce a certain amount of noise after the bubbles burst, which will have an adverse effect on the patient's rest. Therefore, in order to solve the above problems, the present application provides a respiratory oxygen humidification device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] The upper section of the mixing bottle is provided with an airflow secondary mixing section.

[0008] Preferably, the primary mixing section comprises: two Bernoulli tubes arranged opposite to each other, the two Bernoulli tubes are fixedly connected to the air inlet and the water mist inlet respectively, and the oxygen and the water mist are mixed at the front end of the Bernoulli tubes.

[0009] Preferably, the secondary mixing section includes a fan blade rotating at a middle position of the mixing bottle.

[0010] Preferably, a driving member is fixedly connected to the bottom of the mixing bottle, and the driving member is transmission-connected to the fan blades via a transmission assembly.

[0012] Preferably, the secondary mixing section further comprises a funnel piece fixedly connected to the top of the mixing bottle, and the height of the middle position of the funnel piece is lower than the height of the side edge.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] Bernoulli tubes are provided at both the air inlet and the water mist inlet to form a primary mixing section, which can accelerate the airflow and enhance the convection effect of the two. At the same time, a secondary mixing section composed of fan blades and funnels is provided in the mixing bottle to perform secondary mixing of oxygen and water mist, thereby achieving uniform mixing of water mist and oxygen. Compared with the prior art, this method increases the comfort level of oxygen inhalation and reduces the risk of infection.

[0015] By setting up a humidifier, the size of the water mist can be controlled, and adding a valve can improve the control accuracy. At the same time, using a humidifier for humidification can effectively reduce noise and improve the patient's experience. BRIEF DESCRIPTION OF THE DRAWINGS
