Device, system and method for sublingual delivery

A sublingual delivery device comprising:

• a device body having a proximal end and a distal end, said device body comprising:
• a delivery button configured to operate the sublingual delivery device;
• an ampoule carrying liquid comprising an ampoule seal;
• a threaded rod configured to push the ampoule seal towards the proximal end of the device body;
• a joints mechanism configured to convert vertical motion of the delivery button to horizontal motion of the threaded rod;
• an adjustment knob configured to set the volume of liquid to be delivered by the sublingual delivery device by adjusting a rotation degree of the knob, said adjustment knob located at the distal end of said device body;
• and
• a mouthpiece made of a biocompatible material configured to be placed into and have a shape that conforms to the shape of a mouth of a user, said mouthpiece located at the proximal end of said device body, and said mouthpiece surrounding a hollow needle configured to penetrate the ampoule and deliver liquid from the ampoule into the mouth of the user;
• wherein said joints mechanism comprises a ring arm, left and right vertical arms, and left and right arms, said ring arm connected to the left and right arms via a first corresponding joint, and said left and right arms are connected to the left and right vertical arms via a second corresponding joint,
• wherein actuation of the delivery button is restricted to a linear movement in a vertical direction, and when the delivery button is pressed vertically downwards, the left and right vertical arms are pushed down, thereby pulling the left and right arms down and towards the proximal end of the device body, which in turn pulls the ring arm towards the proximal end of the device body, to thereby pull the threaded rod towards the proximal end of the device body,
• further wherein the entire joints mechanism is encapsulated within the device body.
