Description

Oxygen humidifier for medical use and method of use thereof

The invention relates to a humidifying device, in particular to a medical oxygen humidifying device and its application method.

In normal breathing state, the air inhaled from the nasal cavity is heated and humidified by the nasal mucosa, and then enters the lungs through the upper respiratory tract to ensure that the respiratory tract can maintain the proper temperature and humidity. Once the patient cannot breathe normally, it is necessary to use a breathing circuit by inserting an endotracheal tube to supply oxygen to it through the breathing mechanism. Therefore, oxygen supply is one of many supporting measures for disease treatment. However, the humidity of the pure oxygen output by the breathing mechanism is extremely low, and it is difficult to heat and humidify the patient's own upper respiratory tract mucosa, so that it is easy to make the patient feel uncomfortable. It must cooperate with an oxygen humidification device to replace the role of the nasal mucosa to maintain The temperature and humidity of the patient's respiratory tract.

Referring to Fig. 1, an existing medical oxygen humidifier 1 includes a humidification cup 11 for filling a predetermined amount of water, an accommodating space that closes the humidification cup 11 and is provided with an output channel 121 and a cover 12 of an input channel 122, a tubular screen that is inserted into the input channel 122 of the cover 12 and extends toward the accommodating space of the humidification cup 11 13. A flow assembly 14 with a shaft arranged on a top edge of the tubular screen 13 to be located outside the humidification cup 11, an oxygen input joint connecting the flow assembly 14 and communicating the input channel 122 with the tubular screen 13 15, and a pressure gauge 16 located on the oxygen input joint 15.

When the existing medical oxygen humidifier 1 is actually used, oxygen is first introduced through the oxygen input joint 15, so that the oxygen flows through the tubular screen 13 through the input channel 122 of the cover 12 to reach the container. The water in the space, so that the water in the humidification cup 11 is atomized by oxygen, so that the atomized oxygen-containing water gas flows out from the output channel 121 of the cover 12 and is further introduced into the patient's lower respiratory tract middle.

Although the existing medical oxygen humidifier 1 can atomize water into oxygen-containing water vapor for supply to patients. However, in order to achieve the atomization effect of the water, the oxygen flow rate introduced from the oxygen input joint 15 must be sufficient to drive the atomized water through the air flow, generally the best effect is above 10L/min, but if the water level is insufficient, At this time, the atomization time is insufficient, and the atomized water particles are relatively large, which also reduces the humidification effect. Therefore, the existing medical oxygen humidifier 1 needs additional accessories such as the flow assembly 14 and the pressure gauge 16 . In addition, once the water in the humidification cup 11 stays for a period of time, it will easily become a breeding ground for bacteria, which will also cause adverse effects on the medical treatment of patients.

Another oxygen humidification method currently used in medical institutions is to obtain small molecule water vapor by means of ultrasonic waves through power supply. However, the system required for ultrasound is more complicated than the existing medical oxygen humidifier 1, and there are doubts about the safety of oxygen use under the use of electricity.

From the above description, it can be seen that improving the structure of the oxygen humidifier for medical use to provide oxygen-containing water gas to patients for treatment and at the same time solve the problem of bacterial growth is a subject to be broken through by the relevant technical personnel in the technical field to which this case belongs.

Therefore, the first object of the present invention is to provide a medical oxygen humidifier that solves the problem of bacterial growth while supplying oxygen-containing water gas to patients for treatment.

Therefore, the medical oxygen humidifier of the present invention includes a container, a semi-permeable membrane, a cover, a pressing plate, and a screen with a plurality of micropores. The container includes a bottom wall, and a surrounding wall extending upward from a peripheral edge of the bottom wall and defining an opening, and the bottom wall and the surrounding wall jointly define a lower space, and the surrounding wall is provided with a first through A hole and a second through hole farther away from the bottom wall relative to the first through hole. The semi-permeable membrane is arranged on a top edge of the surrounding wall of the container to cover the opening. The cover can openably close the lower space of the container and define an upper space together with the semi-permeable membrane. The cover includes a top wall and a surrounding wall surrounding the top wall. The cover is provided with a first through hole on the surrounding wall and a second through hole close to the top wall relative to the first through hole. The pressing plate is arranged in the upper space of the cover, and can move up and down between the first through hole and the second through hole of the cover and contact an inner surface of the surrounding wall. The screen is arranged in the lower space and spaced apart from the surrounding wall of the container and facing the first through hole of the container.

In addition, the second purpose of the present invention is to provide a kind of medical oxygen How to use the air humidifier.

The method for using the medical oxygen humidifier of the present invention is to use the above-mentioned medical oxygen humidifier and includes the following steps: a step (a), a step (b), and a step (c).

The step (a) is to introduce water from the first pipe member of the upper pipeline assembly, so that the water continuously flows into the upper space from the covered first through hole.

In the step (b), when the water level in the upper space rises so that the pressure plate moves upward, a first hyperbaric oxygen is introduced from the second pipe of the upper pipeline assembly, so that the first hyperbaric oxygen is automatically The covered second through hole is introduced into the upper space and pressurized towards the pressure plate, so that the pressure plate moves downward to force the water in the upper space to permeate through the semi-permeable membrane and filter out a water accumulated in the lower space towards the lower space. Purify water inside the screen.

The step (c) is after the step (b), and the introduction of the first hyperbaric oxygen is terminated when the water level of the purified water in the screen reaches a predetermined height, and the first pipe of the lower pipeline assembly A second high-pressure oxygen is introduced into the channel, so that the second high-pressure oxygen is introduced into the lower space from the first through hole of the container, passes toward the micropores of the screen, and impacts the purified water in the screen, so that the The purified water is atomized into an oxygen-containing water vapor flowing toward the second pipe member of the lower pipe assembly.

The effect of the present invention is: firstly introduce the water from the first pipeline of the upper pipeline assembly to accumulate water in the upper space; The first hyperbaric oxygen is introduced into the second pipeline, thereby The first hyperbaric oxygen pressurizes the press plate to force the water between the press plate and the semi-permeable membrane to permeate through the semi-permeable membrane and accumulate purified water toward the screen; when the purified water in the screen Stop the introduction of the first hyperbaric oxygen when the water level reaches a predetermined height and introduce the second hyperbaric oxygen into the first pipeline of the lower pipeline assembly, so that the second hyperbaric oxygen passes through the screen to face the screen The purified water inside is impacted, so that the purified water is atomized into the oxygen-containing water vapor and drawn out through the second pipeline of the lower pipeline assembly to be supplied to a patient, and at the same time, the problem of breeding bacteria is solved.
