Abstract

The invention discloses a hollow clip for spraying medicine on ear electrodes and a method of using the same. The hollow clip is used to prevent the electrodes from being ineffective due to spraying of anti-inflammatory drugs on the electrodes, and placing the ear electrodes that need to be sprayed with anti-inflammatory drugs into the In the hollow clip, the function of spraying anti-inflammatory drugs on non-electrode positions is realized. The method avoids poor electrode contact and smears anti-inflammatory drugs, has the advantages of simple and reliable device, low manufacturing cost, good process controllability, and quick operation, etc., and is used to solve the clinical situation of ear infection caused by using ear electrodes. The coating position is small, but the effective spraying position can be guaranteed to be more than 80%.

Hollowed-out clamping die for spraying medicine on ear electrode and using method of hollowed-out clamping die

Technical Field

The invention relates to the technical field of biological manufacturing and clinical medicine, in particular to a hollow clamping die for spraying medicine on ear electrodes and a using method thereof.

Background

The ear electrode is mainly used for inserting a tiny electrode into the ear of a patient to enable the electrode to be attached to nerves in the ear, and the tail end of the electrode is connected with equipment such as a hearing aid, so that the patient can better receive auditory information and feed back the auditory information to the brain. Such ear electrodes have been used in clinical medicine, but there is a symptom that inflammation is caused in part of the ears of patients due to insertion of the electrodes. The main manifestation is that the electrode can be well contacted with the ear of a patient, but can be inflamed due to the influence of foreign matters.

In the traditional method, in order to avoid ear inflammation, an anti-inflammatory drug is required to be directly coated on a tiny ear electrode, but the coated anti-inflammatory drug forms an isolation layer to cover the surface of the electrode, so that the electrode cannot be contacted with the nerve in the ear.

Therefore, it is an urgent need to provide a device and method for spraying a drug onto a specific position of an ear electrode without affecting the contact between the electrode and the nerve.

Preferably, the first clamping plate and the second clamping plate are movably connected through a hinge structure.

The invention also provides a using method of the hollow clamping die in the technical scheme, namely a method for spraying medicine on the ear electrode by using the hollow clamping die, which comprises the following steps:

(1) placing the ear electrode into a hollowed clamping die, enabling the hollowed part of the hollowed groove to correspond to the part of the ear electrode needing to be sprayed with the pesticide, and then clamping the hollowed clamping die;

(2) placing the anti-inflammatory drugs in a spraying machine, adjusting the pressure of the spraying machine, and then starting spraying to spray the hollow parts on the two surfaces of the hollow clamping die;

(3) after the spraying is finished, the hollowed-out clamping mold is opened after the anti-inflammatory drug is solidified, the ear electrode is taken out, and then the drug spraying is finished.

According to the technical scheme, compared with the prior art, the invention discloses the hollow clamping die for spraying the medicine on the ear electrode and the using method thereof, and the hollow clamping die has the following beneficial effects:

the method uses the hollowed clamping die to cover the position of the electrode, avoids poor contact of the electrode and coats the anti-inflammatory drug, has the advantages of simple and reliable device, low manufacturing cost, good process controllability, quick operation and the like, can realize quick spraying of the anti-inflammatory drug to the specific position of the ear electrode, and is suitable for clinical medical staff to use.
