The present disclosure describes devices for intranasal drug delivery to targeted regions and sub-regions of a nasal cavity of a subject, including the turbinates. The devices may have a housing with a dispensing element, and a positioning or trigger element coupled to the housing that positions the dispensing element within the nasal channel and limits its depth of insertion. The dispensing element may comprise a side opening for dispensing a composition. Devices of the present disclosure may provide a convenient and effective way to deliver compositions intranasally to the targeted regions and subregions while limiting off-target delivery.

A catheter assembly for use in septoturbinatoplasty procedures. The catheter has a shaft and a primary balloon which comprises a base for positioning against the nasal floor, a roof opposed from the base and a side surface extending therebetween for bearing against a nasal septum and / or an inferior turbinate. The base has a width greater than the roof in a direction transverse to the axis of the shaft. The balloon can be inserted into a patients nasal cavity and inflated to realign the patient's septum and / or treat the turbinate.

The utility model relates to the technical field of medical instruments, and provides a turbinate blood taking needle guard which comprises a three-edged needle, and an inner sleeve used for fixing the three-edged needle is arranged on the outer side of the three-edged needle in a sleeved mode. According to the turbinate blood taking needle sleeve, a three-edged needle inserted into the inner sleeve can be more conveniently fixed through the clamping plate in the inner sleeve, the three-edged needle can be more conveniently replaced, the three-edged needle is driven by the inner sleeve to slide in the outer sleeve, the exposed length of the three-edged needle is adjusted, and due to the fact that tail thorns on the inner sleeve are clamped through the adjusting ring, the tail thorns can be conveniently fixed and replaced. When the adjusting ring slides on the outer sleeve, the inner sleeve can be driven to slide to a proper distance in the outer sleeve, and the adjusting ring can be fixed on the outer sleeve through the fixing assembly on the adjusting ring, so that the outward leakage length of the three-edged needle is fixed, and the distance of the three-edged needle in the outer sleeve through the inner sleeve can be checked through the visual window. The convenience of adjusting the push-out distance of the three-edged needle by the whole needle sleeve is improved.

A device for obliterating the posterior nasal nerve for the treatment of chronic rhinitis, comprising: a radio frequency module comprising a first probe; a laser module comprising a second probe; and a main unit comprising a first power controller and a second power controller, the first power controller and the second power controller being electrically connected to the radiofrequency module and the laser module, respectively, the first power controller setting the output power of the radiofrequency module to 15 watts and applying radiofrequency energy to the anterior, middle, and posterior parts of the inferior turbinate and to the upper, inner, and lower parts of the posterior end of the turbinate in the nasal cavity of a human body by means of the first probe to reduce the volume of the inferior turbinate and ablate the neurovascular structure therein, the second power controller setting the output power of the laser module to 2 watts and applying laser energy to the posterior nasal nerve by means of the second probe to ablate the posterior nasal nerve tissue.

Doxycycline injections improve the appearance of cosmetically significant lower eyelid festoons and malar edema, as well as of the jowls. The doxycycline is also useful for reducing edema of turbinates, the nasal concha or conchae shell-shaped networks of bones, vessels, and tissue within the nasal passageways that are responsible for warming, humidifying, and filtering the air as it is inhaled. The doxycline, in a concentration preferably of greater than 10 to 20 mg / ml, preferably in combination with a local anesthetic and optionally with a vasoconstrictor such as epinephrine and a pH buffering agent, is injected into the subcuticular space at the site of swelling. The high viscosity limits the spread of the doxycycline to the area to be treated. The resulting sclerosis prevents fluid accumulation. The doxycline also decreases swelling due to fat, by causing a decrease in lipomas.

Devices and methods for more effective cryoablation of a posterior nasal nerve. The cryoablation tip of the device is paddle-shaped, with broad, flat, overall rectangular outline with notches on the sides to create a metacentric outline. One side of the cryoablation tip is conductive, while the opposing side is highly non-conductive. Corner portions of the tip are also non-conductive. Intermediate portions of the side-edge surfaces conductive, and are configured as recesses or notches in the side edge. In use, the system will be inserted into the nasal cavity of a patient, with conductive surfaces of the cryoablation tip disposed in contact with portions of the turbinate lining overlying a posterior nasal nerve, and operated to cool those portions to ablate the posterior nasal nerve. The insulative portion of the cryoablation tip protects remaining surrounding tissue from cryoablation.

A septum support or nasal splint that is insertable within a nasal cavity of a patient to maintain a position of a septum of the patient includes a base and a first side member that is positioned on a first side of the base and that extends upward from the base. The first side member is configured to contact the septum of the nasal cavity. The septum support also includes a second side member that is positioned on a second side of the base and that extends upward from the base. The second side member is configured to contact a turbinate of the nasal cavity so as to reinforce the first side member. A lower end of the second side member is securely connected to the base or first side member and an upper end of the second side member is not attached to the first side member.

The invention discloses a deep ice while-drilling anti-vibration gas separation, enrichment and fusion detection device and method, and belongs to the technical field of polar region deep ice drilling. The deep ice while-drilling anti-vibration gas separation, enrichment and fusion detection device is mainly composed of a multi-gas enrichment end, a flow guide plate set, a sensor circuit board and an outer side vibration reduction structure. Wherein the separation and enrichment chamber can realize efficient enrichment and separation of target gas by simulating a turbinate structure of a mouse and a gas separation function. A flow guide structure designed by simulating the nasal cavity of a dog is utilized to guide gas to form vortex, so that the contact time of the gas and the sensor can be prolonged, and the detection sensitivity and accuracy are improved; the outer side vibration reduction structure simulates a sunflower marrow structure and a V-shaped structure of leech epidermis, the contact time can be prolonged, impact energy can be absorbed, the vibration reduction effect is achieved, and the stability and accuracy of a detection system are improved; according to the fusion detection method, multiple types of sensors are used for detecting the target gas, data fusion and dynamic error compensation are achieved, and the detection accuracy and the system stability are improved.
