Abstract
This present invention provides a delivery device that could be used to delivery discreet small volume of expensive biotechnology treatments to specific areas of the oral cavity, or other tissues. The present invention also provides a method of using the device disclosed herein to deliver biotechnology treatments and/or therapeutic agents to specific areas of the oral cavity, or other tissues. In one embodiment, the treatments and/or therapeutic agents are delivered to the interproximal area between and around the teeth.
Claims15
A device for delivering therapeutic agents to a subject, comprising
- a) a peristaltic pump driven by a motor, wherein the peristaltic pump comprises a peristaltic pump head and a pneumatic piston;
- b) a liquid reservoir which is connected to a mixing chamber via pump tubing, wherein the mixing chamber is located above said pneumatic piston and the pump tubing passes through the peristaltic pump head;
- c) a spring which is connected to a shaft of the pneumatic piston;
- and
- d) an outlet channel for dispersing aerosolized therapeutic agents out of the device,
- wherein the peristaltic pump delivers liquid from the liquid reservoir to the mixing chamber via the pump tubing, said liquid is aerosolized in the mixing chamber during a power stroke of the pneumatic piston and delivered to the subject, the peristaltic pump is connected to the motor via a reduction gear and a conversion gear, wherein said reduction gear is articulated with said conversion gear and the conversion gear comprises a smaller diameter gear-set close to an axle of the conversion gear, wherein said smaller diameter gear-set articulates with a gear-tooth section on the shaft of the pneumatic piston.
A device for delivering therapeutic agents to a subject, comprising
- a) a peristaltic pump driven by a motor, wherein the peristaltic pump comprises a peristaltic pump head and a pneumatic piston;
- b) a liquid reservoir which is connected to a mixing chamber via pump tubing, wherein the mixing chamber is located above said pneumatic piston and the pump tubing passes through the peristaltic pump head;
- c) a spring which is connected to a shaft of the pneumatic piston;
- and
- d) an outlet channel for dispersing aerosolized therapeutic agents out of the device,
- wherein the peristaltic pump delivers liquid from the liquid reservoir to the mixing chamber via the pump tubing, said liquid is aerosolized in the mixing chamber during a power stroke of the pneumatic piston and delivered to the subject, the pneumatic piston is drawn back against the spring and then released, thereby generating a power stroke by the reflection of the compressed spring, and when the pneumatic piston is being drawn back, a valve located in the mixing chamber is closed and a valve located outside the mixing chamber is opened to allow air to enter into a chamber above the pneumatic piston.
