Description
MEDICAL DEVICE CONNECTION STATION
TECHNICAL FIELD
The present invention relates to a medical device connection station which is configured to transfer
medical data from a medical er device docked therewith to a remote server system.
BACKGROUND
Increasingly medical computer devices, such as electronically enabled drug ry devices, are
configured to record usage data that s to the usage of the device. In the e where the
medical er device is a drug delivery device, the usage data may include the: administered
dosage regimen, for e, the delivered quantity of a medicament; the associated delivery history;
the adherence to a predetermined dosage regimen. An example of such a drug ry device is
provided in WO 77441, , and WO 2007/088444, the
products pertaining to which are offered by Merck Serono SA under the RebiSmartTM and dT'VI
trademarks. In an alternate example a drug ry device may comprise a communications interface
for communication with an intermediate medical computer device whereon the usage parameters can
be transferred and recorded.
It is desirable to supply the recorded usage data to a server system, such that the data can be
permanently recorded on a database of the server system and subsequently analysed by a health
care professional if necessary. One such way of supplying the recorded data is to configure the above
drug delivery device to be dockable, for data transfer, with a connection station that is in
communication with the server system, wherein data exchange between the drug delivery device and
server system occurs via the connection station. It is advantageous to provide a connection station
with such functionality as opposed to incorporating the functionality in the drug delivery device for
reasons of approval by ing bodies in various ictions, for example, the federal food and
drug agency (FDA) in the US. Notably, drug delivery device incorporating new functionally may take
several years to receive approval, whereas a tion station that works with an approved drug
delivery device does not require such approval.
When using a connection station the drug delivery device is docked with the connection station and
thereafter and actuator may be depressed to effect initiation of a connection and a subsequent data
session between the connection station and server system.
A drawback with such ion of the connection station is that a user may forget to depress the
or, and thus the medical device is docked with the connection station without the required data
session. er, the user may find it difficult to depress the actuator. The aforementioned may be
exacerbated by certain medical conditions, such as Multiple Sclerosis, the conditions of which can
manifest as visual, motor, and sensory problems as well as cognitive problems.

A further drawback is that, for convenience of use, it is desirable to provide a docking interface
between the l computer device and connection station which es in a substantially vertical
direction. However, with such an ement, the g interface of the connection station is
exposed and can thus become contaminated with debris and dust.
A further drawback is that the process of docking the medical computer device with the connection
station and the subsequent sion of the or and initiation of the connection to the server
system delays start-up of the data session.
In certain conventional medical computer devices, a user interface is provided in the form of a display
means for display of the medical data and a user input device comprising selection keys for operation
of the l device. To analyse the medical data, a patient using the device takes the device to a
health care professional (HCP) who, using the user interface, s and views the medical data.
Thereafter, the HCP may manually enter the data into a remote server system wherein it is stored for
future analysis. A drawback with this system is that the HPC may incorrectly enter some of the
medical data into the server system. Moreover, the process of transporting the medical computer
device to the HCP for analysis of the medical data is burdensome on the patient as is entry of the
medical data into the server system by the HCP.
SUMMARY OF THE ION

necessary for the patient to have drug delivery device in their possession when traveling and a
terminal to interface with the server system cannot be guaranteed.
Various objects of the invention are achieved by:
a l device connection n according to claim 1, medical device connection station according
to claim 9;
a system to transfer medical data from a medical device to a server system according to claim 18;
a method of transferring medical data from a medical device to a server system according to claim 20;
a method of transferring medical data from a medical device to a server system according to claim 24;

a drug delivery device according to claim 32.
Disclosed herein is a medical device connection station comprising a body having a first portion of a
docking interface cavity to dock with a corresponding second portion of a docking interface of a
medical device, a control unit controlling a medical device communication interface for communication
with a docked medical device and controlling a server communication interface. The control unit is
configured e medical data from a docked medical device via the medical device communication
interface and is further ured to connect with and obtain a data n with the server system via
the server ication interface, and to y transfer the medical data to the server .
According to a first aspect of the invention, the medical device connection station r comprises a
lid connected to the body and movable between a first and second position, wherein in the first
position the lid prevents first portion of the docking interface from docking with the second portion of
the docking interface of the medical device, and wherein in the second position the first portion of the
docking interface is le to dock with the second portion of the docking interface.
According to a second aspect of the invention the server communication ace comprises a ar
network interface. Advantageously, the medical patient does not need to ort the medical
computer device to the medical practitioner for upload of the medical data to the server, rather upload
can be performed remotely via the cellular network interface. er, the medical computer device
is convenient to use for the HOP since it does not require an intermediate step of the HOP transferring
the medical data to the server system. Moreover, the medical computer device can be used in a range
of locations since the cellular network interface enables wireless communication over the land areas of
each cell. It is advantageous to provide a connection station with such cellular k data transfer
capability as opposed to incorporating this capability in a drug delivery device for reasons of approval
40 by gang bodies in various jurisdictions, for example, the federal food and drug agency (FDA) in

the US. Notably, drug delivery device incorporating new functionally may take several years to receive
approval, whereas a connection station that works with an approved drug delivery device may be
easier to obtain approval, if needed.
By using a medical device connection station to transfer the medical data, as opposed to the medical
device itself, the medical device can be made disposable and the connection n re-usable, such
that relatively expensive components like the ication interfaces and l unit are part of the
connection station. Further, a single connection station can be used by a ity of medical devices,
for example at a ent centre. Yet further, the size and weight of the medical device can be
reduced since the aforementioned components are part of the connection station. This is particularly
advantageous for medical devices that are carried by the patient as part of day to day use.
A dedicated docking connection station to transfer the medical data as opposed to a more general
device, such as a mobile phone, is more convenient to use since the user has merely to dock the
medical device with the connection station to ensure transfer of the medical data. Whereas, in the
example of a mobile phone, a user would need to install application specific software on the phone,
and each time data is transferred, ensure that there is a connection between the medical device and
mobile phone. Moreover, a more l device is inherently less secure.
The medical device connection station comprises a lid movement sensing unit which is configured to
sense movement of the lid between the first position and the second position and to thereby provide a
signal to the control unit, the control unit ured to receive the signal to initiate the connection to
the remote server system.
Advantageously, objects of the invention are solved since the lid is convenient to move from the first
and second position particularly for medical patients who suffer from l conditions with
ms that can exacerbate the difficulty in using such devices. Moreover, the l device
cannot be docked without initiating the connection between the server system and connection station.
The lid also prevents contamination of the docking interface with debris and dust. Moreover, the
connection station automatically ts to the server system when the lid is moved from the first
position to the second position such that when the medical device is uently docked, the
connection station is ready for data er to the server system. In this way the tion station is
convenient to operate and the time a user spends operating the connection station can be reduced.
The medical device communication interface may comprise an infra-red interface or other suitable
means to receive the medical data. For example, it may comprise a near field communication system.
The lid movement sensing unit may be mechanically actuated sing a switch unit and an
actuation member, the actuation member is configured to engage with and actuate the switch unit as

the lid is moved between the first and second position. The switch unit is configured to provide the
signal. Alternatively, the lid movement sensing unit may be light intensity or magnetic field ed.
The lid may be lly connected to the body. Alternatively it may be slideably, translateably or
flexibly connected to the body. For a pivotally connected lid, the actuation member of the lid
movement sensing unit may comprise a cam le to pivot with the lid to actuate the actuation
member, the actuation member being pivotally connected to the body. The lid and body may be
configured such that the lid entirely covers the first portion of the docking interface when in the first
on. The switch unit may advantageously be mounted on a circuit board arranged adjacent a base
of the body distal from the lid. The circuit board may comprise electronic components mounted directly
thereon for the s communications functions and control functions, including ss
telecommunications technology (WTT) (e.g a GSM processing chip), a SIM card slot and connector,
and ed or other forms of near field wireless communication with the medical device received in
the docking interface cavity. The infrared receiver / transmitter may be positioned on the circuit board
just below an ed transparent window formed in a base wall of the docking cavity.
The server communication interface of the tion station may comprise one or more of: a wireless
telecommunications technology (WTT) network interface, in particular a cellular phone network
interface, for e, a GSM, 3G or 4G enabled interface with a SIM card; a wired network interface,
such as a USB or RJ45 connection; a WLAN network interface, such as a IEEE 802.11 standard. In
the example of a WTT network interface the connection station is particularly advantageous since it
enables the transfer of the medical data in remote locations or for field nurses or other health care
personnel visiting patients.
The connection station may comprise a control module having a cryptographic algorithm to encrypt the
received medical data. The control unit may be configured to transfer the encrypted medical data to
the server system. In this way confidential medical data can be ly transmitted and stored.
The lid nt sensing unit may be ured to sense movement of the lid from the second
position to the first position and to thereby provide a further signal to the control unit, the control unit
configured to receive the further signal to ate the connection to the server system. Alternatively
or in addition, control unit may be configured to ate the connection to the server system after a
predetermined period of time. In this way the connection station is energy efficient.
The medical device may be a drug delivery device adapted for subcutaneous delivery of a
medicament or may be adapted for delivery by other means, for example, as an aerosol via an inhaler
or orally. The l data may be related to a dosage regimen of the medicament.

penetration depth and dosage, are obtainable by interface of the medical data ition unit with the
relevant hardware.
The medical device may also be configured to receive data from the tion station, or directly
from the server system via the connection station communication interface or other le
communication interface. The received data may be, for example, a software update, drug ation,
or a new treatment regimen.
Referring now to s 2 — 3, the tion station 10 has a body 14 that comprises a housing 16
consisting of a base 18 side wall 20 and top wall 22. The body 14 further comprises a first portion 24
of the docking interface configured to dock with the second portion 94 of the docking ace of the
medical device 6.
In the example the first portion 24 of the docking interface is arranged on the top wall 20 of the
housing 16 such that the medical device 6 can be conveniently docked in the vertical direction.
However, it may be arranged elsewhere on the housing 16, for example on a side wall 18.
The docking interface comprises any arrangement operable to constrain the medical device 6 in 3-
dimensions to the body 14. For this purpose the first and second ns of the docking interface may
be complementary in shape such that the one of the docking portions fits at least partially within the
other of the docking portions. In the example the first portion 24 of the docking interface comprise a
docking interface cavity 24 that extends between the top wall 22 and base 18 of the housing 16. The
docking interface cavity 24 comprises a bottom wall 28 and side wall 30. The second portion 94 of the
g interface comprises an end of the medical device 6 that is insertable into the docking interface
cavity 24. The side wall 30 of the g interface cavity 24 defines an oval-shaped n with two
parallel sides that correspond to the exterior shape of the medical device 6. It will be iated that
other shapes of medical device and thus docking interfaces can be used.
The docking interface may be shaped such that the l device can only be docked when
orientated correctly. For this e the docking interface may have a asymmetric profile. In the
example an asymmetric profile is embodied by the curvature of the sides of the medical device 6 being
non-symmetric. The second portion 94 and / or first portion 24 of the g ace may be tapered
to facilitate easier docking. In the example an end of the medical device is tapered for this purpose.
