Benefits of technology

This new type of medicine injection device solves problems associated with previous designs such as difficulty piercing or instability during operation due to exposures to contaminants caused by contact before administered (the ear canal). Additionally, this technology prevents accidental disconnection while delivering drugs into the body for treatment purposes without causing damage.

Problems solved by technology

This patents discusses various techniques involving delivering medicines directly inside the middle part (the temporal binaural space) of the human body called the auditory canaliculum. These techniques involve inserting an oculus sheath catheter containing microsponger tubules within the nasophysistrichome without causing inflammation or injury from foreign objects such as metalloid residues present there. Another technique involves introducing certain chemical compounds like trioxacilline sulfate into these spaces where they act specifically against specific enzymes involved in brain function.

Embodiment 1

[0027] Such as Figure 1 to Figure 4 As shown, Embodiment 1 discloses a plug-type tympanic drug delivery device, comprising a tympanic drug delivery tube 1, the head end of which is provided with a puncture needle 2 for puncturing the tympanic membrane into the tympanic cavity, and the tympanic cavity drug delivery tube 1 The tail end is equipped with an earplug type positioning piece 3 for fixing at the entrance of the ear hole; With such arrangement, the puncture needle 2 is convenient for the head end of the tympanic cavity drug delivery tube 1 to smoothly puncture the tympanic membrane and enter the interior of the tympanic cavity. The earplug-type positioning part 3 can make the tympanic administration tube 1 fixed more stably, easy to operate, and the accuracy is also higher; the infusion connector 6 can be easily connected to a syringe to inject medicine, and the infusion connector 6 can be blocked by the sealing cover 7 when not in use.

Embodiment 2

[0038] Such as Figure 5 As shown, Embodiment 2 discloses a plug-type tympanic drug delivery device, which differs from Embodiment 1 in that the structure of the earplug-type positioning member 3 is different.

[0039] Such as Figure 5 As shown, in this embodiment 2, the earplug type positioning member 3 includes a positioning air bag 3.3, and an air bag positioning frame 3.4 is installed between the positioning air bag 3.3 and the tympanic administration tube 1, and the outer surface of the positioning air bag 3.3 is opened There are anti-skid grooves 4. In this way, the positioning airbag 3.3 can be adaptively deformed according to the earhole structure of different patients, and the applicability is better; at the same time, the anti-skid groove 4 provided on the outer surface of the positioning airbag 3.3 increases the stability of the positioning airbag 3.3 in contact with the inner surface of the patient's ear canal. The reliability of fixing the tympanic administrati...

Abstract

The present invention relates to an earplug type tympanic administration device. The earplug type tympanic administration device comprises a tympanic administration tube and is characterized in that ahead end of the tympanic administration tube is provided with a puncture needle for puncturing tympanic membranes to enter tympanic cavity and a tail end of the tympanic administration tube is provided with an earplug type positioning piece to be fixed at an earhole inlet; and the tail end of the tympanic administration tube is connected with an infusion connector and the infusion connector is provided with a sealing cover. The earplug type tympanic administration device has smart structure and reasonable design, the puncture needle is arranged at a head end of the tympanic administration tube, so that the tympanic administration tube can more smoothly puncture the tympanic membranes to enter the tympanic cavity; a part, close to the tail end, of the tympanic administration tube is provided with the earplug type positioning piece which can enable fixing of the tympanic administration tube to be more stable, convenient to operate and also higher in accuracy; and the tail end of the tympanic administration tube is connected with the infusion connector, so that the infusion connector can be conveniently connected with an injector to inject medicines, and the infusion connector can beplugged by the sealing cover when not used.
