Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
An improved method of administering local anesthesia to the gum surrounding a decayed tooth comprising injecting a local anesthesia into the gum surrounding a decayed tooth wherein the anesthesia is injected through a hypodermic syringe and needle, applying ultrasonic vibration to said hypodermic syringe and needle containing said local anesthesia by contacting said syringe and needle with an ultrasonic probe as said syringe and needle penetrate said gum, to increase the diffusion of said local anesthesia into said gum surrounding said decayed tooth, said increase in diffusion of said local anesthesia acting to reduce the amount of said anesthesia required to alleviate pain.
Claim 2
Dependent Claim
103 words
An improved method of administering local anesthesia to the gum surrounding a decayed tooth comprising injecting a local anesthesia into the gum surrounding a decayed tooth wherein the anesthesia is injected through a hypodermic syringe and needle, applying ultrasonic vibration to said hypodermic syringe and needle containing said local anesthesia by contacting said syringe and needle with an ultrasonic probe as said syringe and needle penetrate said gum, to increase the diffusion of said local anesthesia into said gum surrounding said decayed tooth, said increase in diffusion of said local anesthesia acting to reduce the amount of said anesthesia required to alleviate pain.
Claim 3
Dependent Claim
32 words
The method as described in claim 1 further including applying ultrasonic vibration to said decayed tooth to provide additional diffusion of the injected local anesthesia into the gum surrounding the decayed tooth.
Claim 4
Dependent Claim
35 words
The method described in claim 1 further including massaging the injection site of said gum with ultrasonic sound vibration to provide additional diffusion of the injected local anesthesia into the gum surrounding the decayed tooth.
