The invention relates to the technical field of medical data monitoring and early warning, in particular to a dynamic monitoring and early warning system for abnormal function of Eustachian tube. The system is characterized in that a data acquisition module acquires time sequence data of various eustachian tube state parameters such as tympanic chamber vibration, pharyngeal vibration and tympanic chamber air pressure, when a human body is yawn or swallowed, the eustachian tube is opened, the larger the opening is, the stronger the vibration of the tympanic membrane and the pharyngeal is, and the transmission decibel to an external auditory canal is increased, so that a eustachian tube opening section positioning module analyzes the characteristics to determine the auditory canal opening section; the opening amplitude of the Eustachian tube is accurately obtained, and an opening section is accurately cut out; after the Eustachian tube is opened, the air pressure in the tympanic chamber approaches and tends to the external auditory canal air pressure, the health index analysis module divides an approaching section and a leveling section in an opening section based on the air pressure change consistency, analyzes the air pressure change correlation by fusing multi-aspect information, and obtains health indexes by combining section length difference and air pressure difference characteristics; and finally, monitoring and early warning are performed on the Eustachian tube of the monitored object based on the health indexes in a monitoring and early warning module.

The utility model discloses a novel anti-drop ear ventilation pipe, which comprises a pipe body with an external auditory canal end and a tympanic chamber end, a through channel is arranged in the pipe body, the inner side wall of the pipe body axially extends towards the tympanic chamber end to form a bending part, and when the tympanic chamber end of the pipe body is implanted into a tympanic membrane, the tympanic membrane is inserted into the tympanic chamber end of the pipe body. And the bending part can be bent towards the periphery of the tube body so as to enlarge the contact surface with the inner side of the tympanic membrane. The ventilation pipe can be better fixed to the tympanic membrane after the bending part with the extension bending performance is expanded and unfolded, the ventilation pipe is effectively prevented from falling off, the surface of the pipe body is provided with the silver ion coating with the antibacterial characteristic, the antibacterial effect is achieved, the pipe body is provided with the cutting edge, the tympanic membrane can be cut open conveniently, the ventilation pipe is arranged, and the ventilation pipe is convenient to use. And the use experience of the user can be better improved.

This invention provides a biodegradable Eustachian tube support and a biodegradable Eustachian tube support system. The biodegradable Eustachian tube support includes a connected Eustachian tube receiving portion and a middle ear receiving portion. The Eustachian tube receiving portion, when in an expanded state without external force, is tubular and has a hollow, through-hole cavity. After implantation into the Eustachian tube, the Eustachian tube receiving portion is in the expanded state to open the Eustachian tube. The middle ear receiving portion includes a linear base structure. When not subjected to external force, the base structure itself forms a three-dimensional winding shape in space. After implantation into the tympanic cavity, the base structure forms the three-dimensional winding shape, filling the area of ​​the tympanic cavity adjacent to the Eustachian tube to maintain communication between the tympanic cavity and the Eustachian tube, while preventing the Eustachian tube receiving portion from sliding. Both the Eustachian tube receiving portion and the base structure are made of biodegradable materials.

The utility model discloses a tympanic cavity ventilation drainage tube which comprises a tube body, a through hole is formed in the tube body in the axial direction in a penetrating mode, two limiting parts are arranged at one end of the tube body in the radial direction in an extending mode, the two limiting parts are symmetrically arranged along the axis of the tube body, the two limiting parts can be folded towards each other, and the tube body is in a conical shape. The outer diameter of the pipe body is gradually increased in the axial direction in the direction away from the limiting part. The tympanic cavity ventilation drainage tube can reduce the possibility that the tympanic cavity ventilation drainage tube falls off from the tympanic membrane and falls into the tympanic cavity or falls out of the external auditory canal, and therefore use safety is improved.

The utility model relates to the technical field of medical equipment, in particular to a tympanic membrane ventilation pipe. The device is suitable for tympanic membrane catheterization. The tympanic membrane ventilation pipe comprises an inner claw, a pipe body and an outer claw, the pipe body is a hollow pipe, the two ends of the pipe body are fixedly connected with one end of the inner claw and one end of the outer claw respectively, and the other ends of the inner claw and the outer claw are free ends; the free end is made of memory alloy, is in a straightened state at the temperature of 0 DEG C and is in a bent state at the temperature of 20-40 DEG C. The structure is newly innovated, and an existing traditional indwelling catheter structure is changed. And the free ends of the inner claw and the outer claw are bent in a normal-temperature state through the memory alloy. The bending state of the inner claw and the outer claw achieves multi-point and internal and external bidirectional fixation, the bending state of the inner claw and the outer claw increases the supporting area and the supporting firmness, multi-point firm fixation of the eardrum in the ear is ensured, internal and external bidirectional fixation is achieved through bidirectional fixation of the inner claw and the outer claw, and the risk that the eardrum falls out of the auditory meatus and falls into the tympanic chamber is thoroughly solved.

A collapsible medical device configured to be implanted in the tympanic chamber of a recipient is presented herein. More specifically, the medical device has a folded configuration having a physical size (physical footprint occupied by the device) / first form factor that enables insertion of the device through the recipient's ear canal (e.g., through an opening formed at the recipient's tympanic membrane). After the device is inserted into the tympanic chamber, the medical device is deployed from a folded configuration to an expanded configuration. In the expanded configuration, the medical device has a physical dimension (physical footprint occupied by the device) / second form factor greater than the physical dimension in the folded configuration. In some examples, the medical device is configured to be positioned against a projia of a recipient's ear adjacent to a tympanic chamber.
