A pathogen examination unit includes a working side, two non-working sides, and an entrance side. The working side of the pathogen examination unit may include a panel that is positioned between two users, such as between a healthcare worker and a patient. In some cases, the pathogen examination unit places one user, such as the healthcare worker, inside the pathogen examination unit, which reduces the number of surfaces and objects that must be disinfected between patients.

In an example, a ventilator includes an outer container containing liquid, an inverted container submerged in the liquid to provide inverted container space between a closed top and an inner container liquid level; gas supply line to supply breathing gas to the inverted container space; and inhalation line having an inlet in the inverted container space to provide breathing gas to patient. The inverted container moves upward from a first elevation when the inverted container space reaches a hydrostatic delivery pressure and volume of the inverted container space increases. The inverted container stops moving upward and the gas supply line stops supplying when the inverted container reaches a second elevation above the first. Based on a breath demand signal or preset timing, the inhalation line opens to permit flow of breathing gas to the patient at the hydrostatic delivery pressure, lowering the inverted container due to lost buoyancy resulting in sinkage.

A device to provide sterilized and purified breathable air and to disinfect exhaled air and includes a housing having a first and second opening. The housing includes at least one partition having a plurality of holes, and within the housing such that a plurality of compartments is formed between the first opening and the second opening, and at least one ultraviolet (UV) light source positioned in each of the plurality of compartments. The UV light source is UVC LED lights to emit UVC light of a predefined wavelength within the plurality of compartments to sterilize and purify the air while flowing through the housing. The device includes a mask fluidically coupled to the second opening of the housing using a flexible second pipe to provide the purified air. The device includes one-way valves at the second opening of the housing, and two one-way valves at the outlets of the mask.

An incentive spirometer medical device having a mouth piece protected by an enclosure when not in use and being able to be operated by one hand to open to access the mouth piece.

An apparatus for the treatment of a liquid that includes a chamber having at least one inner surface, the chamber adapted for passage of a fluid therethrough. The chamber is at least 80 percent enclosed. The apparatus also includes an optional ultraviolet-transmissive tube disposed within the chamber and also adapted for the passage of the liquid therethrough. The apparatus further includes an ultraviolet lamp disposed within the chamber and, optionally, within the ultraviolet-transmissive tube. A reflective material is interposed between the chamber and the transmissive tube. The reflective material is adapted so as to reflect at least a portion of light emitted by the ultraviolet lamp, wherein the reflective material is at least 80 percent reflective.

A portable device for the decontamination of a breast. The aim of the device is to reduce the risk of mastitis, even when the patient has a medicament incompatibility. For this purpose, the invention includes a decontamination unit which decontaminates the breast at least by means of a physical method.

A protective assembly having a protective sheath assembly with a tubular catheter body with a proximal and distal end, and at least one connection fitting at the proximal end; and a holding device assembly with a housing, an introducer tip, a retention device. The tubular catheter body provided graduated marks or a moveable marker to identify depth of penetration. The protective assembly can deliver anesthetic to a tract, and serve as a protective sheath for medical devices.

A method of using ultraviolet (UV) radiation to treat an infection in the respiratory system and far infrared radiation (FIR) to treat inflammation. The method uses a light probe inserted into the airway of a patient to apply UV radiation and FIR to a target site in the upper respiratory tract. The UV radiation applied may be broad-spectrum UV radiation or UVC radiation in the 222 nm range. FIR applied may be in the 3-10 μm range. The UV radiation kills any organisms, including COVID-19 and FIR reduces inflammation resulting from infection and subsequent UV treatment. The treatment may be applied to intubated or spontaneously breathing patients and via the oral or nasal passages.

In an example, a ventilator includes an outer container containing liquid, an inverted container submerged in the liquid to provide inverted container space between a closed top and an inner container liquid level; gas supply line to supply breathing gas to the inverted container space; and inhalation line having an inlet in the inverted container space to provide breathing gas to patient. The inverted container moves upward from a preset minimum elevation when the inverted container space reaches a hydrostatic delivery pressure and volume of the inverted container space increases. The inverted container stops moving upward and the gas supply line stops supplying when the inverted container reaches a preset maximum elevation. Based on a breath demand signal or preset timing, the inhalation line opens to permit flow of breathing gas to the patient at the hydrostatic delivery pressure, lowering the inverted container due to lost buoyancy resulting in sinkage.
