Ringer’s solution control device with linear and precise flow rate control

 

 

Client / Market

• Hospital and clinic requiring precise flow rate control (fields requiring precise injection of ringer’s solution e.g. anticancer drug injection, etc.)

 

Necessity of this Technology

• When injecting the ringer’s solution, a cheap disposable precise flow rate controller is provided for linear flow rate control.
• Existing flow controller cannot control the flow rate precisely resulting in parabolic flow pattern with control wheel operation and accurate flow rate estimation and control was impossible. Therefore, an expensive infusion pump was used for treatment that requires precise injection such as cancer treatment. However, precise flow rate control is also difficult with this device, and due to its expensive price, it could not be popularized.
• The device enables cheap and disposable tool for precise linear flow rate control to overcome the problems in cost and controllability of existing fluid treatment.

 

Technical Differentiation

• Realized a cheap, disposable flow rate controller with accurate linearity control
• Contributed to expansion of treatment of symptoms that can be treated with fluid treatment and improvement of treatment effect
• Realized the concept of flow rate controller with satisfactory price and performance
• Existing method of controlling the flow rate with the rotary controller uses a circular flow channel and linear flow rate control is fundamentally impossible. Therefore, for each treatment and for every flow rate adjustment, the flow rate change has to be checked every time.
• Linear flow rate control is a function that is not even guaranteed in an expensive infusion pump.
• This invention adopts a linear movement structure for the flow rate controller to enable precise linear flow rate control, and since it is disposable, the pricecompetitiveness has been secured

 

Excellence of Technology

• Unlike existing apparatus that uses a rotary controller for the ringer’s solution pass through, by using a worm gear that enables linear movement in the flow rate controller, the nonlinearity and possibility of error in the process of the rotary movement are fundamentally eliminated.
• In the invented flow rate controller, the flow rate controller that moves linearly by the rotor moves to show the travel range of the ringer’s solution and how the flow path area changes.
• Linearly changing flow path area and travel route enables linear flow rate control.
• Has worked for KIMM from 2004 to present, and invented 17 technologies (1,780 million won as fixed payment + running royalty) during the period
• During the same period, 136 patents were applied and 93 were registered.
• Received the 2007 Korea Intellectual Property Office’s Patent Award (The Most Excellent Researcher Award) and commissioner’s prize from Korea Intellectual Property Office in 2014
