5 results about "Nasal passage" patented technology

Compositions for use in preventing or treating an infection of the nasal passages, sinuses, or both of a subject are described. The compositions include one or more peptoid compounds in an amount effective to prevent or treat the infection in the nasal passages, sinuses, or both. The compositions include the one or more peptoid compounds in an amount effective to inhibit one or more pathogenic bacteria, pathogenic fungus, or pathogenic virus in the nasal passages, sinuses, or both, while having relatively little or no activity against commensal bacterial species, commensal fungal species, commensal viral species, or any combination thereof, in the nasal passages, sinuses, or both of the subject.

A patient interface may include a dual chamber cushion assembly having a nasal chamber and an oral chamber. The nasal chamber may be arranged to deliver pressurized breathable gas to a patient's nasal passages, and the oral chamber may be arranged to deliver pressurized breathable gas to the patient's oral passages. The nasal chamber may be pressurized to a different level than an oral chamber to promote nasal breathing. An air passage may fluidly connect the nasal chamber and the oral chamber so that pressurized breathable gas may flow from the nasal chamber to the oral chamber.

This invention discloses a traditional Chinese medicine nasal inhalation powder for facial meridian clearing and nasal closure, and its preparation method. The powder is prepared from the following raw materials in parts by weight: 5-10 parts musk, 12-17 parts angelica dahurica, 15-20 parts peppermint, 7-12 parts black sedge, 12-17 parts pearl, 15-20 parts asarum, and 10-30 parts soapberry. This traditional Chinese medicine nasal inhalation powder and its preparation method for facial meridian clearing and nasal closure exhibit multi-target synergistic effects. The effects of this invention are remarkable. The formula is scientific, with the various herbs working together. Musk and Asarum are the principal herbs, which have a strong effect of opening the orifices, refreshing the mind, dispelling wind and cold. Angelica dahurica and Gleditsia sinensis are the assistant herbs, which dispel wind and dry dampness and open the nasal passages. Zaocys dhumnades dispels wind and unblocks the meridians. Peppermint is cooling and dispersing. Pearl detoxifies and promotes tissue regeneration. Together, they assist the principal and assistant herbs in their effects. This combination can not only quickly relieve facial muscle spasms and numbness, but also improve local microcirculation and promote the recovery of nerve function. Nasal administration is fast-acting and takes effect by utilizing the rich vascular network and olfactory nerve pathway of the nasal mucosa.

This invention provides a topical Chinese medicine ointment that is fast-acting and effective in preventing and treating allergic rhinitis. The drug composition in this invention can quickly clear nasal passages, clear heat and detoxify, reduce inflammation and swelling, and stop nasal discharge, thereby relieving symptoms and reducing the possibility of recurrence. The topical application of this Chinese medicine ointment is easier to adhere to, and it does not have the side effects of Western medicine hormones. It can fundamentally protect the nasal mucosa, reduce the invasion of allergens, improve symptoms, and reduce the recurrence rate.

This invention discloses an ENT drug delivery device and system in the field of medical device technology. The device includes a drug delivery catheter assembly comprising a main tube segment, a daughter tube segment, and a terminal drug delivery device. The daughter tube segment has several joint units distributed along its axial direction, which are hinged to each other. Each joint unit contains an angle sensor. A grip handle is detachably connected to the drug delivery catheter assembly and contains an electric infusion pump and a flow sensor. The grip handle is detachably connected to a support plate. A central processing unit (CPU) is also located inside the grip handle and is connected to the flow sensor, angle sensor, and electric infusion pump. This invention utilizes a multi-degree-of-freedom independently adjustable structure formed by spherical hinges, combined with a serpentine structure, to allow the atomized drug delivery direction to be independently adjusted in pitch and rotation angles based on the bending posture of the daughter tube segment. This effectively covers laterally hidden lesions such as deep nasal passages, pharyngeal recesses, and the surface of the tympanic membrane, eliminating drug delivery blind spots.
