  • Publication number: 20240207524
    Abstract: A one-step anesthetic buffering carpule is advantageously disposed within a syringe so as to provide a pH-raising buffer that mixes with the carpule anesthetic just prior to injection. A puncture unit is disposed within a rubber plunger containing the buffer. The puncture unit is manually actuated to detach a rubber plunger seal so as to mix the buffer with the anesthetic.

  • Patent number: 11260177
    Abstract: A dental anesthetic buffer system has a carpule having a first end and a second end, a capsule at least partially disposed within the carpule proximate the first end so as to fluidly seal the first end, and a membrane disposed proximate the second end so as to fluidly seal the second end. A liquid anesthetic is contained within the carpule between the first end and the second end. A liquid buffer is contained within the capsule. An activator is disposed proximate the buffer and extends from the carpule first end. The activator is manually moved from a first position to a second position so as to release the buffer from the capsule and combine the buffer with the anesthetic.

  • Patent number: 10493206
    Abstract: A dental anesthetic buffer assembly advantageously attaches to carpule-loaded syringe in the same manner as a standard disposable needle. The dental anesthetic buffer assembly, however, incorporates a pH-raising buffer that advantageously dissolves into and mixes with the carpule anesthetic during injection, in lieu of pre-mixing the buffer and anesthetic prior to injection.
