Sterilization Humidifier

Humidification of the air can cause wallpaper to peel or foster mold growth on furniture. The sterilization humidifier is an effective solution to this problem.

This device sterilizes the water and air by boiling it and spraying it with silver ions. It also minimizes microbial transmission by reducing the droplet size and power consumption.

Water Storage Reservoir

A humidifier has a water storage reservoir to store water. The water in the humidifier is used to generate and discharge hygienic moisture. In acute care hospitals, it is common practice to use sterile water in disposable oxygen humidifier reservoirs for the delivery of low-flow oxygen therapy. It is also a standard procedure to clean the disposable oxygen humidifiers weekly, using tap or sterile water. However, the contaminant-filled (mineral-laden) air from the humidifier reservoir can cause respiratory diseases and allergies. For the elderly and weakened patients, breathing volatile chemicals and allergens projected along with fine water droplets can be harmful to their health.

The present invention provides a method and apparatus for sterilizing the water in the reservoir of the humidifier. The apparatus includes a humidification unit 130 to receive a portion of the water in the reservoir, a spray port 130a for generating moisture, an electrode 150 installed to be immersed in the water of the reservoir, and a salt supply unit 160 for selectively supplying salt into the reservoir.

When a sensor of the humidifier detects that the water 121 has been in the reservoir 120 for a long time, e.g. by a sensor measuring the weight of the water or the water level, the electrical conductivity measurement unit 180 measures the conductivity of the water 121. If the measured electrical conductivity is lower than a first predetermined value, a saturated salt solution 165 having a 38% concentration of salt is supplied from the salt supply unit 160 into the reservoir 120 through a valve 168 (S150).

Reservoir Sterilization

The humidifier 100 according to the present invention senses that the water 121 stays in the reservoir 120 for a long time by a sensor measuring the weight of the reservoir or the water level. In this case, it is very likely that bacteria or germs propagate in the reservoir. Therefore, the humidifier 100 sterilizes the water 121 in the reservoir.

When the water level in the reservoir 120 falls below a predetermined height, a float control 48 opens a solenoid control valve 50 and a sterilant mixture from a sterilant supply cylinder 52 is fed into the reservoir through line 54. When the sterilant mixture in the cylinder 52 is at a high concentration, Top Fill evaporation Humidifier it forms hypochlorous acid in the reservoir 120. The hypochlorous acid has sufficient sterilizing power to kill bacteria and germs in the reservoir.

Alternatively, the control unit 190 can also measure the value of the measured electrical conductivity of the water in the reservoir 120. If the value of the electrical conductivity is less than a first predetermined value saturation stored in the salt supply unit 160, it supplies a saturated salt solution 165 into the reservoir 120 to maintain an amount of hypochlorous acid having enough sterilizing power in the reservoir 120.

In addition, a biochemical indicator is preferably installed in the reservoir 120 to indicate whether or not the disinfectant in the humidifier 100 has sufficiently killed microorganisms. The biochemical indicator is a FDA-cleared commercial preparation of spores (e.g. Geobacillus stearothermophilus for steam) intended specifically for the type of sterilization method used in each cycle.

Sterilization Method

Every day, hospitals perform a large number of surgical procedures. During these procedures, many medical instruments come in direct Top Fill evaporation Humidifier contact with the patient’s skin or mucus membranes. Inappropriate sterilization or disinfection of these devices can lead to the transmission of pathogens. Such pathogens include multidrug resistant bacteria (e.g. MRSA, VRE, extended spectrum b-lactamases, and metallo b-lactamase producers), fungal spores, viruses, and other pathogens.

A humidifier is a device that increases humidity in the air by spraying water particles into the atmosphere. It can also be used to irrigate wounds and help patients breathe easier. It is important to use a sterilized humidifier to prevent the spread of diseases and infections.

Humidifiers can contain pathogens, such as fungi and bacteria, in their water tanks. These microorganisms can cause respiratory problems and skin irritations in patients. To reduce the risk of these infections, humidifiers should be emptied and sterilized regularly.

A sterilized humidifier is a great way to improve the quality of air in your home. It can alleviate the symptoms of dry skin and throat, as well as other discomforts caused by winter weather. These devices can also reduce static electricity and cracks in walls or wallpaper. It’s important to choose a humidifier that has a low water warning indicator and shuts off automatically when it is empty.

Sterilization Device

A sterilization device that sprays hygienic moisture free from pathogens and bacteria. This device can fundamentally prevent infection with diseases such as influenza and tuberculosis by fundamentally destroying pathogens and bacteria without the need for excessive heat. This is a method that can be utilized to replace an autoclave, hydrogen peroxide vapor, radiation or ethylene oxide (EtO) gas sterilization methods. It is also a method that can be used to sterilize medical devices that cannot be sterilized using other methods due to their size, shape or material composition.

The humidifier 100 according to the present invention senses that water 121 stays in the water tank for a long time and supplies enough chlorine ions from the salt supply portion to make sterilized moisture whenever the electrical conductivity of the water measured by the water reservoir sensor is lower than the first predetermined value. This sterilization process is repeated when the water 121 in the reservoir is consumed by bacteria or pathogens.

It is important to sterilize medical devices that come into contact with sterile body tissues and fluids because any microbial contamination could lead to disease transmission. For this reason, it is essential to have reliable and effective sterilization methods for semi-critical and critical medical devices, such as duodenoscopes, bronchoscopes, cystoscopes/ureteroscopes. Sterilization validation is performed by using biological indicators to show that the sterilization process destroys the anticipated pre-sterilization bioburden and the resistant biological indicator populations.
