When encountering blood scab and other difficult cleaning material, still can pass through the reverse rotation sealing sleeve, enhances the water pressure of shower nozzle port, promotes the cleaning effect.

The application discloses a posterior naris filling device with a ventilation tube, which comprises a blind end, a ventilation tube body and a filling capsule body, wherein the filling capsule body is fixedly arranged in the blind end and covers three fourths of the surface of the blind end; a ventilation hole is arranged in the region of the blind end which is not covered by the filling capsule body; and the rear end of the blind end is communicated with the ventilation tube body. The posterior naris filling device with the ventilation tube is inserted into the nasal cavity and the nasal meatus or the inferior nasal meatus, the filling capsule body fills the posterior naris, the ventilation tube body supplies air to the rear end of the nasal cavity of the patient through the ventilation hole of the blind end, the pain of the patient during the filling process and after the filling is reduced, the blind end is adapted to the shape of the nasopharynx and is fixed by the filling capsule body, and the blind end is not easy to move with the swallowing activity, so that the patient can also breathe through the nose after the filling, the discomfort after the filling is greatly reduced, and the treatment effect and the comfort of the hemostasis by filling are greatly improved.

This utility model discloses a device for nasopharyngeal ventilation, belonging to the field of medical device technology, to solve the problem of pressure sores easily caused by prolonged insertion of a nasopharyngeal airway. The device includes an airway body and an airbag. The airway body includes an airway outlet connector located at the end of the airway body inserted into the patient's pharynx. The airbag is located at the other end of the airway body and arranged around it. The airbag includes a fixed end and a supporting end. The fixed end is fixedly connected to the other end of the airway body, and the supporting end extends radially outward along the airway body. This nasopharyngeal ventilation device provides flexible protection for the patient's lip skin, thereby preventing pressure sores.

This utility model discloses a nasopharyngeal irrigation spray nozzle, including a main structure, a pressing component disposed on the main structure, and a sprayer connected to the outer periphery of the pressing component. The sprayer can be rotated relative to the pressing component to adjust its angle. By applying pressure to the pressing component, the pressing component absorbs nasopharyngeal irrigation solution within the bottle and then sprays it out through the sprayer into the patient's nasal cavity. The nasopharyngeal irrigation spray nozzle of this utility model allows for angle adjustment by rotating the sprayer relative to the pressing component, facilitating easier insertion of the sprayer's nozzle into the patient's nasal cavity, thereby better spraying the medication into the nasal cavity of a lying patient.

The utility model discloses a novel anti -slip nasopharyngeal airway, including flexible double -layer air pipe and nasal cavity air bag, and the inflatable cavity is formed between the outer layer and the inner layer of air pipe, and the center of inner layer is the air pipe line that penetrates before and after, and the air pipe is completely flattened and is in flat shape when not being inflated, and is circular pipe shape when being full of air, and the front end surface of air pipe is equipped with elastic sleeve, and elastic sleeve sleeve connects air inlet joint, and nasal cavity air bag movable sleeve connects the position of air pipe outside near air inlet joint. The utility model adopts the inflatable double -layer air pipe that has the set shape after being full of air, and designs the auxiliary guide rod of specific shape to guide the double -layer air pipe into the nasopharynx of patient, and the probability of rubbing contact with the nasal mucosa of patient is smaller when guiding into the nasopharynx of patient, and the occurrence of the damage hemorrhage condition is avoided.

The application discloses a non-contact nasopharyngeal tissue hardness measuring endoscope, and relates to the technical field of nasopharyngeal detection equipment. The non-contact nasopharyngeal tissue hardness measuring endoscope comprises an endoscope body, a probe body and a host control unit; the probe body is an elongated instrument capable of entering the nasopharynx through the nasal cavity, and an optical observation module and a micro-displacement detection module are coaxially integrated on the front end of the probe body in the axial direction; the non-contact mechanical excitation module further comprises a hemispherical porous micro-nozzle and an excitation control unit; the hemispherical porous micro-nozzle is rotatably buckled with the front end of the probe body; the micro-nozzle comprises a hemisphere, the micro-displacement detection module is axially inserted into the middle part of the hemisphere; a spherical shell-shaped air groove is formed in the interior of the hemisphere, and a micro-pore communicating with the air groove is formed on the spherical surface of the hemisphere; the micro-pores are arranged in an annular layered and optical axis staggered manner, so that the biopsy positive rate is significantly improved, the pathological false negative rate is reduced, and the clinical diagnosis adaptability is improved.
