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.
Claims2
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.

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.
