Abstract
Abstract A device useful in the injection of an anesthetic into the peribulbar region of the eye. The device includes a needle assembly functionally integrated with a flange shaped to provide pressure to the desired region. The device in combination with a syringe and needle allows the injection of anesthetic under pressure and directed toward the peribulbar region of the eye, adequately distributing the anesthetic throughout the peribulbar space more efficiently.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
A device for delivering peribulbar anesthesia comprising: a) a syringe assembly comprising: a needle hub including a proximal end, a distal end, and first threaded connector means therebetween; a hollow needle having a length of 0.5 to 0.75 inches attached to the distal end of said needle hub; and a syringe barrel including a plunger assembly attached to the proximal end of said needle hub; and b) a flange releasably attached to said syringe assembly comprising: a semi-circular skin-contacting side including means for transmitting sufficient pressure to space between the inferior orbital ridge and the lower eyelid of a patient to prevent the deposit of anesthetic throughout tissue in said space; a semi-circular syringe-receiving side; and a portion defining a tunnel between said skin-contacting side and said syringe-receiving side, said portion including second threaded connector means for engaging said first threaded connector means, wherein said proximal end of said needle hub is located proximal of said syringe-receiving side and said distal end of said needle hub is located proximal of said skin-contacting side.
Claim 2
Independent Claim
173 words
A device for delivering peribulbar anesthesia comprising: a) a syringe assembly comprising: a needle hub including a proximal end, a distal end, and first threaded connector means therebetween; a hollow needle having a length of 0.5 to 0.75 inches attached to the distal end of said needle hub; and a syringe barrel including a plunger assembly attached to the proximal end of said needle hub; and b) a flange releasably attached to said syringe assembly comprising: a semi-circular skin-contacting side including means for transmitting sufficient pressure to space between the inferior orbital ridge and the lower eyelid of a patient to prevent the deposit of anesthetic throughout tissue in said space; a semi-circular syringe-receiving side; and a portion defining a tunnel between said skin-contacting side and said syringe-receiving side, said portion including second threaded connector means for engaging said first threaded connector means, wherein said proximal end of said needle hub is located proximal of said syringe-receiving side and said distal end of said needle hub is located proximal of said skin-contacting side.
Claim 3
Independent Claim
228 words
A method of delivering peribulbar anesthesia to a patient comprising the steps of: a) providing a device for delivering pefibulbar anesthesia comprising: i) a syringe assembly comprising: a needle hub including a proximal end, a distal end, and first threaded connector means therebetween; a hollow needle having a length of 0.5 to 0.75 inches attached to the distal end of said needle hub; and a syringe barrel including a plunger assembly attached to the proximal end of said needle hub; and ii) a flange releasably attached to said syringe assembly comprising: a semi-circular skin-contacting side including means for transmitting sufficient pressure to space between the inferior orbital ridge and the lower eyelid of a patient to prevent the deposit of anesthetic throughout tissue in said space; a semi-circular syringe-receiving side; and a portion defining a tunnel between said skin-contacting side and said syringe-receiving side, said portion including second threaded connector means for engaging said first threaded connector means, wherein said proximal end of said needle hub is located proximal of said syringe-receiving side and said distal end of said needle hub is located proximal of said skin-contacting side; and b) injecting anesthetic into the peribulbar region of a patient while simultaneously applying pressure to space between the inferior orbital ridge and lower eyelid of said patient to prevent the deposit of anesthetic throughout tissue located in said space.
Claim 4
