Patent Application

The present invention relates to a vibrative anesthesia device for pain reducing, particularly to a vibrative anesthesia device, which reduces pain caused by injection by means of vibration, for example, during anesthesic injection in the oral cavity.
Comfort and pain reducing for patients are of principal importance in the field of medical safety. Transmission of stimuli by a variety of peripheral nerves can effectively reduce pain feeling of patients.
Peripherial nerves of the human body are different in nature, therefore the feeling transmitted by them are also different. Peripheral nerves for transmitting temperature and pain are very tiny, non-isolated and of low signal density, while peripheral nerves for transmitting pressure and vibration are thicker, isolated and of high signal density. Therefore, when pain and vibration occur at the same time, vibration signals transmitted by the isolated nerves will control the pain feeling transmitted by non-isolated nerves. At this time patient feels almost only the vibration, while the pain feeling is reduced. Patient feels even painless. That is the “Gate Control Theory”.
By the Gate Control Theory for inhibiting pain, surface anesthesia is not necessary. A device for pain reducing by means of vibrative anesthesia generates high-frequency-vibration, and furthermore stimulates peripheral nerves to transmitte vibration, and prevent pain feeling from being tranmitted to the brain, thus comfort and savety of a patient is upgraded.
Taiwan Utility Model Patent Bulletin No. M443510 disclosures a “Handheld Device for Pain Reducing” for reducing pain feeling of a patient. However, this device has following disadvantages: 1. high production costs, since the structure of the device is complicated; 2. fields of application are limited, due to the that ring-shape it can only be used for injection on a flat surface, but not for injection in an oral cavity or at bumpy parts.
The main object of the present invention is to provide a vibrative anesthesia device for pain reducing, which has a simple structure and is usable in an oral cavity, wherein pain reducing or even painless feeling of a patient are achieved.
For achieving above object, a vibrative anesthesia device for pain reducing of the present invention comprises: a grip for hand gripping; an electrical component set inside of said grip, with a protruding cable; a vibration component, connected with the cable of the electrical component, usable for setting in oral cavity; with vibration generated by the vibration component, so that pain reducing or painless feeling are archieved.
It is preferred that the grip has a control switch for starting or dosing the vibration component.
The control switch can control the amplitude and/or frequency of the vibration component, so that the controller can adjust the amplitude and/or frequency according to a using situation.
For easy operating the electrical component is a battery.
It is preferred that the vibration component comprises: a case, having a predetermined shape; and a driver, set inside of the case, electrically connected with that electrical component; by choosing different shapes of case, different requirements are satisfied.
The ease has an elliptic shape, which is appropriate for setting in an oral cavity.
The grip has a duct, which coates the cable outsides, for protecting said cable.
Said duct is a rigid body, for easy controlling of the location of the vibration component.
Said duct is as a flexible body, for easy operating.
Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the present invention.
As shown in
The grip 1 for hand gripping, having a control switch 11 for starting or closing the vibration component 3, wherein the control switch 11 can control the amplitude and/or frequency of the vibration component 3, thus it is easy for user to adjust the amplitude and/or frequency.
Owing to easy operating the electrical component 2 is a battery, a protruding cable 21 is used for electrical connection with the vibration component 3. Besides, the electrical component 2 can also be a rechargeable power device for using charger (not shown), or an external power supply device, as alternative for the user according to the requirements.
As shown in
In practice, setting the vibration component 3 between gums and lips, then starting the vibration component 3 for patient to feel vibrative, thereafter by anesthetical injection pain reducing or painless feeling is achieved. Therein the grip 1, electrical component 2 and the vibration component 3 are simple, light structured, easily to use, therefore producing and material costs are saved.
While preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments, which do not depart from the spirit and scope of the invention.
