Flexibility Debiotech’s
JewelPUMP™ is
made of two parts: one re-usable part (that contains the electronics with a
large display, vibration alarm, buzzer and programming capabilities, as well
as remote communication for distant programmation and control) and one
disposable part (with the reservoir and the pumping mechanism, as well as
batteries) for almost one week treatment. Reservoir filling is done only once
for 6 days and small air bubbles don’t need to be evacuated as they are retained in the
reservoir by a new type of filter. Once both parts are assembled together,
the entirely waterproof unit is attached to the skin with an adhesive patch
that contains an auto-inserted infusion cannula with no tubing which can be
changed every 3 days. The unit can be removed and reattached at will to the
existing adhesive patch, or to a new one at another location, enabling more
freedom for the patient. We also have another version of the re-usable
electronic part which includes bolus buttons directly on the pump, for a self
administration in the event the remote is not immediately available. Size The
JewelPUMP™ comes with an insulin reservoir capacity of 4.5ml (450 U),
representing a total volume in use of 22 cc and a total weight of 0.78oz
(22g, incl. battery). With such a small size (approx. 60x40x13mm), it can be
hidden under the clothes and makes the disease almost invisible. Size is
often perceived as a major issue for patients: pumps are heavy and
cumbersome. The JewelPUMP™ is up to four times smaller than today’s
conventional pumps, or about half the volume of existing patch pumps, while
containing over two times the amount of insulin on board, and therefore
represents a clear progress in patients’ daily life.
Precision The MEMS
technology used in the JewelPUMP™ allows a very tight control and
precision of the pumping mechanism. Each pump actuation delivers only 200
nanoliters of drug (0.02 U), and reproducibility is better than 5%, bringing
it very close to physiological delivery of insulin. This precise control may
also extend the use of pumps for children who have low need of insulin and
where injection must be especially well controlled. On the longer run, we are
also working here in Safety Safety is guaranteed
by several features: closed fluidic path at rest, anti-free-flow system,
permanent functional monitoring and immediate occlusion detection. In
addition to the safety features present on current insulin pumps, the
JewelPUMP™ is preventing air from entering the fluidic path, while also
being able to detect any malfunction or end of reservoir within few
actuations, a long time ahead of existing pumps. Affordability Unlike
other insulin pumps, the JewelPUMP™ does not require such a substantial
financial investment upfront as current pumps. Its design, with a permanent
part containing the electronics and a disposable part containing the
reservoir and the pumping mechanism, makes it affordable and attractive for
every patient: patients who are already on a pump therapy and want to improve
their quality of life, patients who want to start a pump therapy and patients
who don’t need a permanent supply of insulin (such as type
II patients) but who would like to benefit from a pump therapy. |
