Description

Technical Field

[0001] The invention belongs to the technical field of oxygen humidification, in particular to an oxygen humidification device for oxygen supply. Background Art

[0002] The respiratory department mainly treats a series of respiratory diseases such as bronchitis, pneumonia, emphysema, respiratory distress syndrome, bronchiectasis, pleural effusion, etc. With the aging of the population, various respiratory diseases that damage respiratory function are increasing, such as severe chronic obstructive pulmonary disease and cor pulmonale. These diseases often cause decompensated acute respiratory failure after infection or thoracic and abdominal surgery. In the process of treating patients in the respiratory department, the use of ventilators to deliver oxygen has become a routine treatment method.

[0003] However, oxygen itself is a dry pure gas. When the human body inhales it directly, it will feel dry and uncomfortable. Therefore, it is particularly important to humidify the oxygen before inhaling it. Although the existing oxygen humidification equipment has solved the problem of oxygen dryness to a certain extent, it still has many shortcomings.

[0004] After searching, in an oxygen humidification device for oxygen supply with announcement number CN221692459U, the utility model discloses an oxygen humidification device for oxygen supply, including a humidifier, wherein an atomization chamber and a mixing chamber are arranged inside the humidifier, and an oxygen inlet is fixedly connected to the upper wall of the humidifier near the left wall.

[0005] When the humidifier bottle of the above oxygen humidifier equipment is replaced, the original humidifier bottle is taken out after opening the top cover, and the connector is taken out together through the threaded connection with the humidifier bottle. Because the connector is connected to the humidifier by a long hose, it will not cause separation from the humidifier. The new humidifier bottle is opened and the connector is unscrewed from the original humidifier bottle, and the new humidifier bottle is inserted and tightened, and then installed in the shell. The pure water is deeply sterilized and disinfected by turning on the ultraviolet sterilization lamp to prevent the patient from inhaling contaminated water. The pure water can be heated by arranging an electric heating plate on the inner wall of the shell. The heated pure water is atomized and mixed with oxygen, which can effectively increase the temperature of the oxygen and improve the comfort of the patient when breathing oxygen. However, there are still some problems in specific use:

[0006] 1. The above oxygen humidification equipment does not have a drainage structure. When the device is in use, the water molecules in the oxygen will condense and easily flow back along the oxygen tube and block the oxygen tube. At the same time, the liquid blocking the oxygen tube is likely to spray toward the user's face through the flow of oxygen, causing discomfort to the user;

[0007] 2. The above oxygen humidification equipment does not have a humidity adjustment function. When using the device, since each user has a different degree of oxygen humidity acceptance, the same oxygen humidity is difficult to adapt to all users, which may cause some users to feel uncomfortable.

[0008] Therefore, in view of the above problems, an oxygen humidification device for oxygen supply is proposed. Summary of the invention

When the number of the three filter discs 55 located at the lower part of the third fixing hole 15 for air outlet is more, more humidity in the humidified oxygen can be adsorbed, so that the humidification degree of oxygen is reduced; when the number of the three filter discs 55 located at the upper part of the third fixing hole 15 is more, the content of water molecules in the humidified oxygen can be more, thereby achieving effective regulation of oxygen humidity, so that the device can be adapted to patients with different humidity requirements.

[0052] A method for using an oxygen humidification device during oxygen supply, which is used for the instructions for use of the above-mentioned oxygen humidification device during oxygen supply, is characterized in that it comprises at least the following steps:

[0053] Step 1, device installation: add an appropriate amount of pure water into the humidifying bottle 1, connect the bottle cap 4, and fix the humidifying bottle 1 through the fixing frame 3, then connect the oxygen supply tube 2 to the oxygen source, and then connect the recovery mechanism 6 to the oxygen tube;

[0054] Step 2, oxygen humidity adjustment: When the oxygen humidity content requirement is high, the three filter discs 55 in the adjustment structure 5 are adjusted to the upper part of the third fixing hole 15 according to the humidity content requirement, so as to reduce the contact between oxygen and the filter discs 55 and maintain the humidity content in the oxygen;

[0055] When the oxygen humidity content requirement is low, the three filter discs 55 in the adjustment structure 5 are adjusted to the lower part of the third fixing hole 15 according to the humidity content requirement, so as to increase the contact between the oxygen and the filter discs 55, filter out the water molecules in the oxygen through the filter discs 55, and reduce the humidity content in the oxygen;

[0056] Step 3, liquid recovery: The oxygen entering the humidification bottle 1 enters the semi-disc cavity shell 61 in the recovery mechanism 6 after humidification. The oxygen entering the semi-disc cavity shell 61 will collide with the baffle 64, causing the larger water molecules contained in the oxygen to condense in advance and fall downward and be collected in the collection bottle 67.

[0057] Working principle:

[0058] First, add a proper amount of pure water to the humidifying bottle 1, then connect the oxygen supply tube 2 to the oxygen source, connect the second connecting tube 63 in the recovery mechanism 6 to the oxygen tube, and finally, fix the humidifying bottle 1 to the card slot 34 in the connecting block 32 fixedly mounted on the wall or other objects through the card block 35 fixed at the rear of the fixing ring 36 of the humidifying bottle 1, and then it can be used;

[0059] During use, the humidity of oxygen can be controlled by adjusting the adjustment structure 5 according to the user's requirements for oxygen humidity. When the user needs a higher oxygen humidity content, the three filter discs 55 in the adjustment structure 5 can be adjusted as much as possible to the upper part of the third fixing hole 15 connected to the recovery mechanism 6 to increase the humidity of oxygen. When the user needs to reduce the humidity of oxygen, the three filter discs 55 in the adjustment structure 5 can be adjusted to the lower part of the third fixing hole 15 so that the three filter discs 55 can filter out water vapor in the humidified oxygen to reduce the content of water molecules in the oxygen.

[0060] Then, the oxygen enters the recovery mechanism 6 through the third fixing hole 15. In the semi-disc cavity shell 61 in the recovery mechanism 6, the oxygen will collide with the baffle 64, and cause the larger water molecules contained in the oxygen to condense and fall in advance and be collected in the collection bottle 67 at the bottom of the semi-disc cavity shell 61. The subsequent oxygen is discharged into the oxygen tube through the second connecting tube 63 to supply oxygen to the user.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
