The invention relates to an electrostatic aerosol disinfection and sterilization method. The method includes the following steps: atomizing liquid water without any medicine to obtain atomized particles of liquid water; and carrying the atomized particles on Static electricity of a first polarity; transporting atomized particles with static electricity to a predetermined surface of an object to be disinfected, the objects to be disinfected have static electricity of a first polarity; when the atomized particles reach the object to be disinfected When the predetermined surface is changed, the electrostatic polarity of the object to be disinfected is changed, so that the object to be disinfected has static electricity of a second polarity, wherein the second polarity is opposite to the polarity of the first polarity. The present invention is capable of treating and slowing down various respiratory diseases caused by viruses, including new pneumonia that threatens people all over the world, greatly improves the effect of disinfection and sterilization, is not only safe and reliable, but also has simple operation and low cost.

Systems and methods are provided for anesthetizing a tympanic membrane of an ear. The systems are personalizable to ensure proper anesthetizing solution administration. The systems and methods may also be useful for administering a solution to the ear canal of a human patient and for maintaining the solution therein.

The present invention discloses an auxiliary visible light rod for multisource end-expiratory CO.sub.2 monitoring. The auxiliary visible light rod comprises a handle, a pump body, a medicine compartment, a rod body and a bracket. The handle is separately connected with the medicine compartment, the pump body and the rod body, and one end of the rod body is connected with a rod head. A lamp and an atomizing head are arranged in the rod head. A circuit tube is connected with the external wall of the rod body, one end of the circuit tube is connected with a display screen, and the other end of the circuit tube is connected with a camera in the rod head. The bracket sleeves the rod body and is fixed to the outer side of an oral cavity or a chin of a patient, and thus the stability of the rod body is improved.

A method of using nanoparticle (NP) spray to treat an infection in the respiratory system and far infrared radiation (FIR) to treat inflammation. The method uses a spray probe inserted into the airway of a patient to apply mSiO.sub.2 and FIR to a target site in the upper respiratory tract. FIR applied may be in the 3-10 μm range. The mSiO.sub.2 spray kills any organisms, including COVID-19 and FIR reduces inflammation resulting from infection. The treatment may be applied to intubated or spontaneously breathing patients and via the oral or nasal passages.

A nasal spray device can include housing having a sensor and a nozzle having a housing interface with a graphical image thereon. The sensor can be configured to sense movement of the graphical image when the nozzle moves relative to the housing, for instance during administration of medicine from the nasal spray device. The sensor can include an infrared proximity sensor that senses infrared reflectivity from the graphical image. The infrared proximity sensor can also be used to measure distance to a surface of a vial within the housing to thereby detect insertion of the vial into the housing.

Aspects and embodiments of the present invention generally include a device for patient self-administration of a prescribed medication. The total quantity of doses to be contained in the device, the quantity of prescribed medication comprising each individual dose, and the dosing schedule, collectively referred to as prescription parameters, are determined and controlled solely by a health care provider (HCP) such as the patient's physician. In accordance with a prescribed dosing schedule, the device makes available for administration the precise quantity of prescribed medication constituting an individual dose. Patient access to the medication as well as patient control of the device is limited solely to the aspects of the device necessary to administer the available dose; that is, the patient has no control over the prescription parameters utilized by the device; that is, the quantity of a dose, the availability of individual doses, the schedule at which the doses are made available to the patient, nor the prescribed medication itself which is contained in the device. Preferably, the device also has a monitored subassembly which detects and transmits relevant device information to a remote management system accessible to the HCP, including detected attempts to alter, access, control or otherwise tamper with the device beyond its prescribed use. Advantageously, HCPs may render sufficient oversight and control over the device and its use to mitigate the risks associated with patients self-administering potentially dangerous or abusable medication without direct, in-person supervision.

An assembly with a handpiece assembly configured to receive electromagnetic energy and fluid, and to selectively deliver the electromagnetic energy and/or the fluid to a target surface. The handpiece assembly includes a handpiece housing and a plurality of fluid lines extending through the handpiece housing. The plurality of fluid lines can transfer fluid from a proximal end of the handpiece assembly to a distal end of the handpiece assembly. A spray mixer can be positioned at the distal end that is coupled to fluid lines of the plurality of fluid lines. An air input port can be positioned at the proximal end that is configured to be coupled to an auxiliary air hose, and an air delivery channel can be coupled to the air input port, and can supply air to a tip of an exchangeable applicator that can be coupled to the distal end of the handpiece housing.

Apparatus and methods for delivering humidified breathing gas to a patient a provided. The apparatus includes a humidification system configured to deliver humidified breathing gas to a patient. The humidification system includes a vapor transfer unit and a base unit The vapor transfer unit includes a liquid passage, a breathing gas passage, and a vapor transfer device positioned to transfer vapor to the breathing gas passage from the liquid passage. The base unit includes a base unit that releasably engages the vapor transfer unit to enable reuse of the base unit and selective disposal of the vapor transfer unit. The liquid passage is not coupled to the base unit for liquid flow therebetween when the vapor transfer unit is received, by the base unit.
