Abstract

Abstract An anesthesia device comprising, a syringe having a barrel defining a chamber, a hollow needle at a distal end of the syringe, and a plunger for pumping fluid from the chamber through the needle. The device has a holding member having a wall with an inner diameter slightly larger than the outer diameter of the syringe barrel, an open proximal end, and an opening at a distal end of the holding member, with the wall defining a cavity to receive the syringe barrel. The device has an elongated cannula having a lumen, and a plurality of apertures in a distal portion of the cannula communicating with the lumen. The device has a hollow adapter secured to a proximal end of the cannula. The adapter receives a distal portion of the syringe with the needle received in the cannula lumen, and the holding member receives the syringe and attached cannula with the syringe barrel received in the holding member cavity, and with the cannula extending distally from the holding member opening. Alternatively, the holding member receives the syringe while the cannula is unattached to the syringe with the syringe barrel received in the holding member cavity, and with the syringe needle extending distally from the holding member opening.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 176 words
An anesthesia device, comprising: a syringe having a barrel defining a chamber, a hollow needle at a distal end of the syringe and having a sharp distal end, and means for pumping fluid from the chamber through said needle; a holding member having a wall with an inner diameter slightly larger than the outer diameter of the syringe barrel, an open proximal end, and an opening at a distal end of the holding member, with said wall defining a cavity to receive the syringe barrel; an elongated cannula having a lumen, and a plurality of apertures in a distal portion of the cannula communicating with said lumen; and a hollow adapter secured to a proximal end of the cannula, said adapter receiving a distal portion of the syringe with the needle received in the cannula lumen, and said holding member receiving the syringe and attached cannula with the syringe barrel received in the holding member cavity, with the cannula extending distally from the holding member opening, and with the adapter releasably received in the holding member.
Claim 2
Dependent Claim 176 words
An anesthesia device, comprising: a syringe having a barrel defining a chamber, a hollow needle at a distal end of the syringe and having a sharp distal end, and means for pumping fluid from the chamber through said needle; a holding member having a wall with an inner diameter slightly larger than the outer diameter of the syringe barrel, an open proximal end, and an opening at a distal end of the holding member, with said wall defining a cavity to receive the syringe barrel; an elongated cannula having a lumen, and a plurality of apertures in a distal portion of the cannula communicating with said lumen; and a hollow adapter secured to a proximal end of the cannula, said adapter receiving a distal portion of the syringe with the needle received in the cannula lumen, and said holding member receiving the syringe and attached cannula with the syringe barrel received in the holding member cavity, with the cannula extending distally from the holding member opening, and with the adapter releasably received in the holding member.
Claim 3
Dependent Claim 17 words
The device of claim 1 wherein the holding member has a distal annular shoulder defining said opening.
Claim 4
Dependent Claim 45 words
The device of claim 2 wherein the adapter has a proximal annular flange, with said flange having a larger diameter than the inside diameter of said shoulder, such that the flange engages against the shoulder when the cannula is fully inserted into the holding member.
Claim 5
Dependent Claim 41 words
The device of claim 1 wherein said syringe has a distal tip, and including a hub securing the needle to said tip, said hub extending through the holding member opening when the syringe only is fully inserted into the holding member.
Claim 6
Dependent Claim 22 words
The device of claim 1 wherein said holding member has an outwardly directed flange at a proximal end of the holding member.
