Problems solved by technology

Increased trauma to the patient with risk of additional damage to the cochlea
The drug in the fluid reservoir requires a micropump to provide pressure to deliver the drug to the inner ear, and the micropump also needs to be implanted in the body, and the cost is relatively expensive

Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with accompanying drawing.

[0027] like figure 1 As shown, the middle ear repeated drug delivery device of the present invention includes a hollow pouch 1 and a connecting tube 2 connected below the pouch, and a one-way valve is provided at the connection between the pouch and the connecting tube; wherein, the The top of the pouch is open and a biological semipermeable membrane 11 is arranged at the opening, and a groove 12 is arranged laterally above the pouch to facilitate connection with the malleus handle. The middle ear repeated drug delivery device (including pouch and connecting tube, etc.) of the present invention adopts the same biocompatible material (such as silica gel, polyethylene, Teflon, etc.) as the external surface of the cochlear implant.

[0028] The bio-semipermeable membrane (collodion film, cellophane, etc.) provided at the opening above the pouch according to the present inv...

Abstract

The invention relates to the field of medical apparatuses in the otology department, in particular to a middle ear repeated dosing device and an artificial cochlea implanted electrode. The middle earrepeated dosing device comprises a hollow bag and a connecting pipe connected to the lower side of the bag. A check valve is arranged at the joint of the bag and the connecting pipe. An opening is formed in the upper side of the bag and provided with a biological semi-permeable film. The bag is placed between malleus and incus long crus. The upper side of the bag makes contact with a tympanic membrane. A groove is transversely formed in the upper side of the bag. The groove of the bag is clamped on a malleus handle. A quite safe, convenient and economical new technique method is created for relieving the cochlea electrode implanting traumatic reaction, conducting regeneration inducing and substituting on auditory nerve cells, optimizing the artificial cochlea implanting effect and improving the speech recognition ability of a patient.

Description

technical field [0001] The invention relates to the field of otological medical devices, in particular to a middle ear repeated drug delivery device and a cochlear implant electrode. Background technique [0002] Cochlear implantation has been widely used clinically. While opening the cochlear implant electrodes, injecting drugs, neurotrophic factors, genes and cells into the inner ear can reduce inner ear damage, promote inner ear nerve repair, supplement and induce auditory nerve cell regeneration . Thereby improving the effect of cochlear implantation and improving the speech recognition ability of patients. [0003] Since the U.S. FDA officially approved the application of multiconductor cochlear implants in adults in 1984, 300,000 deaf people around the world have regained their hearing through cochlear implants. Electrodes in the cochlea restore some hearing by direct electrical stimulation of the nerve tissue (spiral ganglion cells) near the electrode contacts. Ele...
