Description

TRANSMITTER FOR TRANSMITTING SENSOR DATA
The invention relates to a transmitter for transmitting sensor data as measured by a sensor that is connectable to said transmitter, for example a glucose sensor, said transmitter comprising connecting means for mechanically connecting to said sensor and at least one electrical contact for providing an electrical connection with said sensor. Said transmitter may in particular be a transmitter that is worn on the body of a person during use of the transmitter and sensor.
Such a transmitter is known per se. Said known transmitter and sensor each comprise at least one and for example three electrical contacts for providing an electrical connection there between when the sensor is connected to the transmitter. The applicant has found however that the electrical connection between the sensor and transmitter may fail, for example due to the at least one electrical contact of the transmitter being moved out of its normal location, which may be caused by the sensor exerting a force thereon. lt is an object of the invention to improve the transmitter of the type described in the preamble, for example by reducing the chance and preferably preventing that the electrical connection between the sensor and transmitter fails.
This object is met by a transmitter of the type described in the preamble that in accordance with the invention comprises at least one guiding and/or blocking element for guiding a movement of the sensor with respect to the transmitter during connecting to and disconnecting from the transmitter in at least one direction and/or orientation and/or for blocking a movement of the sensor with respect to the transmitter when connected to the transmitter in at least one direction.
The applicant has found that said sensor may in particular exert a force on the at least one electrical contact of the transmitter during connecting to and disconnecting from the transmitter and/or when the sensor is connected to the transmitter in use of the transmitter and sensor. This may be due to said sensor not being connected to or disconnected from the transmitter in a correct direction and/or orientation and/or due to relative movement between the transmitter and sensor when these are worn on the body of a person due to movements of that person. Said at least one guiding and/or blocking element may guide the movement of the sensor with respect to the transmitter during connecting to and disconnecting from the transmitter in at least one direction and/or may block a movement of the sensor with respect to the transmitter when connected to the transmitter in at least one direction, thereby reducing the chance that said sensor exerts a pressure on said at least one electrical contact and therefor reducing the chance that said at least one electrical contact is moved out of its normal position.
Said at least one guiding and/or blocking element may in particular be an additional element of said transmitter in addition to the connecting means. In other words, although the connecting means may provide blocking of the movement of the sensor with respect to the transmitter in an axial direction away from said transmitter to keep the sensor connected to the transmitter which is the inherent function of the connecting means and optionally also in other directions, the at least one guiding and/or blocking means may provide additional blocking of the relative movement between the sensor and transmitter. The at least one guiding and/or blocking element may in particular block the movement of the sensor with respect to the transmitter in at least one direction other than said axial direction away from said transmitter, for example in a direction tilted with respect to said axial direction and/or in a rotational direction with respect to said axial direction.
The sensor is preferably guided in an axial direction towards said transmitter during connecting thereto and preferably guided in an axial direction away form said transmitter during disconnecting therefrom. The sensor is preferably guided during connecting and disconnecting in such a manner that the sensor is in a correct, i.e. desired, orientation with respect to the transmitter, in particular with respect to a surface thereof comprising said connecting means. The sensor is preferably guided during connecting and disconnecting in such a manner that the sensor is aligned with respect to the connecting means.
By connecting the sensor to the transmitter in a correct direction and/or orientation and/or by maintaining the sensor in a correct position and/or orientation when it is connected to the transmitter, the chance of moving the at least one electrical contact out of its normal position is at feast reduced and preferably prevented.
In an embodiment the at least one guiding and/or blocking element protrudes with respect to a surface of said transmitter, said surface being the surface that comprises said connecting means.
During connecting and disconnecting the sensor to and from the transmitter said sensor may contact the protruding guiding and/or blocking element and may thereby be guided in a desired direction and/or orientation. When the sensor is connected to the transmitter the protruding guiding and/or blocking element overlaps part of said sensor and may thereby prevent said sensor from moving with respect to the transmitter, in particular prevent movement of the sensor in the direction of said protruding guiding and/or blocking element
Said protruding at least one guiding and/or blocking element preferably protrudes substantially orthogonal with respect to said surface.
Said at least one guiding and/or blocking element preferably protrudes substantially in the axial direction of the transmitter, i.e. in the longitudinal direction of the transmitter which is the direction of connecting and disconnecting the sensor to and from the transmitter.
Said surface comprising said connecting means may for example be a surface comprising for example two receiving openings and preferably at least one receiving opening of a respective recess for receiving for example a snap fit connector of the sensor.
Said protruding at least one guiding and/or blocking element is preferably located at an edge zone of said surface, wherein said at least one guiding and/or blocking element protrudes from said surface. Said edge zone may in particular be one of the edge zones that extends substantially parallel to the skin of the person wearing the transmitter during use of the transmitter and in particular be the edge zone that is furthest away from the skin out of said two parallel edge zones, i.e. the upper edge zone. Because said at least one guiding and/or blocking element protrudes with respect to this upper edge zone a tilted movement of the sensor part that extends outside of the surface of the transmitter comprising the connection means in an upward direction, i.e. away from the skin of the person, is substantially blocked by the at least one guiding and/or blocking element, while a tilted movement of the outward extending part of the sensor in the direction of the skin is allowed to some extend and allows the transmitter and sensor assembly to have some flexibility with respect to the skin. It is especially the tilted movement in the upward direction of the outward extending part of the sensor, resulting in a tilted movement in the downward direction of the part of the sensor that extends inside of the transmitter, that may cause said at least one electrical connection of the transmitter to be pressed out of its normal location, and which may thus be prevented by said at least one guiding and/or blocking element. Because said at least one guiding and/or blocking element protrudes with respect to this upper edge zone a rotational movement of the sensor with respect to the transmitter about the axial axis that extends in the axial direction may be prevented as well, which rotational movement may otherwise also cause said at least one electrical connection of the transmitter to be pressed out of its normal location.
Said at least one guiding and/or blocking element may preferably extend along a substantial part and preferably the entire length of said edge zone or, if a plurality of guiding and/or blocking elements are provided, said guiding and/or blocking elements may be distributed along a substantial part and preferably the entire length of said edge zone.
Said protruding at least one guiding and/or blocking element can alternatively be seen as an extended part of an upper surface of the transmitter, said upper surface being the surface that extends parallel to the lower surface that is in contact with the body of the person in use of the transmitter, and which extended part extends beyond or protrudes with respect to said surface comprising the connecting means. Said surface comprising the connecting means extends substantially orthogonal with respect to the upper surface and in particular substantially orthogonal between the lower and upper surface.
Said protruding least one guiding and/or blocking element may provide an additional advantage of protecting the part of the sensor that extends out of the surface of the transmitter comprising the connecting means and/or may provide an additional advantage of not having the outward extending part of the sensor being taped onto the body of the person, thereby reducing at least one tape and thereby the inconvenience of removing that tape from the body.
Practically the at least one guiding and/or blocking element comprises a guiding and/or blocking surface.
Said guiding and/or blocking surface may be the surface that guides and/or contacts the sensor during connecting and/or disconnecting to and from the transmitter and/or may block the movement of the sensor with respect to the transmitter when connected thereto. If said at least one guiding and/or blocking element comprises is arranged at the upper end zone of the surface as described above, or, in other words, if the upper surface of the transmitter comprises said extended or protruding part, the guiding and/or blocking surface thereof may be the lower surface of the at least one guiding and/or blocking element, i.e. the surface facing towards the skin of the person wearing the transmitter and sensor assembly during use.
In an embodiment of the transmitter according to the invention the shape of the guiding and/or blocking surface is adapted to the shape of a surface of the sensor that extends substantially parallel to and is facing towards the guiding and/or blocking surface during connecting to and disconnecting from the transmitter and/or when the sensor is connected to the transmitter.
As a result of the corresponding shapes guiding the sensor during connecting and disconnecting to and from the transmitter and/or blocking the movement thereof when being connected to the transmitter may effectively take place.
Said surface of the sensor that extends substantially parallel to and is facing towards the guiding and/or blocking surface during connecting to and disconnecting from the transmitter and/or when the sensor is connected to the transmitter may alternatively be referred to as the surface of the sensor that is guided by the guiding and/or blocking element during connecting to and disconnecting from the transmitter and/or is blocked by the blocking element in the connected condition.
For example, the guiding and/or blocking surface may comprise a substantially concave area adapted to a convex area of the sensor. Such a sensor having a convex area is a sensor that is available on the market and according to this embodiment the shape of the guiding and/or blocking surface is adapted thereto.
In an embodiment of the transmitter according to the invention the at least one guiding and/or blocking element is an integral part of the transmitter.
As described above, said the at least one guiding and/or blocking element may for example be defined by an extended part of the upper surface of the transmitter and may therefor for example be an integral part of the upper surface of the transmitter.
In an embodiment of the transmitter according to the invention the at least one guiding and/or blocking element has a length that is chosen such that the sensor is guided by the guiding and/or blocking element before it contacts the electrical contacts of the transmitter during connecting. 5 An advantage thereof is that the sensor is already aligned with respect to the transmitter before it contacts the at least one electrical contact of the transmitter, such that the risk that the at least one electrical contact is moved out of its normal location is at least reduced and this is preferably prevented. As a result hereof, the sensor is also still guided when it no longer contacts the at least one electrical contact of the transmitter during disconnecting.
Depending on the sizes and/or configuration of the sensor and transmitter used the skilled person would know how to choose the length of the at least one guiding and/or blocking element such that the above is achieved.
In an embodiment of the transmitter according to the invention the at least one guiding and/or blocking element has a length that is chosen such that a distance between a front end of the at least one guiding and/or blocking element and a contact part of the electrical contacts is longer than a distance between a front end of the sensor and a surface of the sensor that is guided by the guiding and/or blocking element during connecting to and disconnecting from the transmitter,
This way it may be achieved that the sensor is already aligned with respect to the transmitter before it contacts the at least one electrical contact of the transmitter during connecting and still after the contact with the at least one electrical contact is lost during disconnecting.
The frond end of the at least one guiding and/or blocking element and the front end of the sensor are defined here in the direction of connecting the sensor and transmitter to each other, wherein the front ends are the ends that face each other during connecting.
The distance between the front end of the sensor and the surface of the sensor that is guided by the guiding and/or blocking element during connecting to and disconnecting from the transmitter is more in particular defined between the front end of the sensor and the frond end of said surface that is guided.
The frond end of the sensor may be defined by a protruding part of the sensor.
Said protruding part of the sensor may comprise at least one electrical contact of the sensor.
The invention also relates to an assembly of a transmitter as described above in any one or more of the above described embodiments and/or having any one or more above described features, alone or in any suitable combination, and a sensor, wherein the sensor comprises second connecting means arranged for cooperating with the connecting means of the transmitter, wherein said sensor is mechanically connectable to the transmitter by means of said connecting means and said second connecting means, wherein the sensor comprises at least one second electrical contact and wherein in a connected condition in which the sensor is mechanically connected to the transmitter the at least one second electrical contact contacts a corresponding at least one electrical contact of the transmitter.
In an embodiment of the assembly according to the invention the at least one guiding and/or blocking element has a length that is chosen such that the sensor is guided by the guiding and/or blocking element before it contacts the at least one electrical contact of the transmitter during connecting and as explained above thereby also after it no longer contacts the at least one electrical contact of the transmitter during disconnecting.
In an embodiment of the assembly according to the invention the at least one guiding and/or blocking element has a length that is chosen such that a distance between a front end of the at least one guiding and/or blocking element and a contact part of the electrical contacts is longer than a distance between a front end of the sensor and a surface of the sensor that is guided by the guiding and/or blocking element during connecting to and disconnecting from the transmitter.
Further and/or alternative features of the assembly will be apparent from the embodiments of the transmitter according to the invention.
Advantage(s) of such an assembly will be apparent for the skilled person from the above provided description describing the transmitter according to the invention.

In the following description same parts are referred to by the same reference signs. If a figure contains reference signs that are not discussed in greater detail in the corresponding figure description, this reference is discussed in preceding or subsequent figure descriptions.
Figures 1 - 8 show a transmitter 1 according to a first embodiment of the invention for transmitting sensor data as measured by a sensor 20 that is connectable to said transmitter 1.
Figures 1-3 and 8 show the transmitter 1 and sensor 20 in a disconnected state and figures 4-7 show the transmitter and sensor 20 in a connected state. The sensor 20 is in this example a glucose sensor that is available on the market. The transmitter 1 may in particular be a transmitter 1 that is worn on a body of a person.
The transmitter 1 comprises first connecting means 2, which are in this embodiment embodied as recesses that are able to receive corresponding snap fit second connecting means 21 of the sensor 20. The first connecting means 2 and second connecting means 21 are provided for mechanically connecting the transmitter 1 and sensor 20 to each other. In a connected state in which the transmitter 1 and sensor 20 are mechanically connected to each other as shown in figures 4-7 first electrical contacts 3 of the transmitter 1 are in contact with second electrical contacts 22 of the sensor 20, as is best visible in figures 6 and 7. It is noted that for the sake of simplicity the first electrical contacts 3 of the transmitter 1 are not shown in figures 1 — 4. It is further noted that the lower side of the transmitter 1 as shown in for example figure 2 is in use covered by a cover, but this cover is not shown in the figures to able to show the inside of the transmitter 1. All electronics and other features arranged inside the transmitter 1 are not shown for the sake of simplicity. As is best visible in figures 6 and 7, if the sensor 20 moves in a rotational direction about the longitudinal axis L of the transmitter 1 as shown by the arrow in figure 7 or in a tilted direction with respect to said longitudinal axis L as shown by the arrows in figure 6 the sensor 20 may exert a force on the first electrical contacts 3 of the transmitter 1 and may thereby push the first electrical contacts 3 out of their normal position. Due to this the electrical contact between the first electrical contacts 3 and second electrical contacts 22 may decrease or get lost. The sensor 20 comprises protruding elements 23 that fit into recesses 4 of the transmitter 1 to prevent relative movement between the sensor 20 and transmitter 1 during use, but the applicant has found that this might not be sufficient to overcome this problem,
In accordance with the invention the transmitter 1 comprises in this embodiment one guiding and/or blocking element 5 for guiding a movement of the sensor 20 with respect to the transmitter 1 during connecting to and disconnecting from the transmitter 1 in at least one direction and/or orientation and/or for blocking a movement of the sensor 20 with respect to the transmitter 1 when connected to the transmitter in at least one direction. In particular, the guiding and/or blocking element 5 guides the sensor 20 to move in a substantially longitudinal direction during connecting and disconnection in such an orientation that the sensor 20 is aligned with respect to the transmitter 1, such that for example the second connecting means 21 are aligned with respect to the first connecting means 2 and the protruding part 24 of the sensor 20 comprising the electrical contacts 22 is aligned with respect to an opening 6 of the transmitter 1 through which said protruding part extends when connected. In particular, the guiding and/or blocking element 5 may prevent or at least reduce relative movement of the sensor 20 with respect to the transmitter lin a rotational direction about the longitudinal axis L as shown in figure 7 and in a tilted direction with respect to the longitudinal axis L wherein the outward extending part of the sensor 20 that extends out of the transmitter 1 when connected thereto cannot move or only very slightly move in an upward direction, i.e. in the direction of the upper side of the transmitter 1, which is defined here as the side of the transmitter 1 that comprises the guiding and/or blocking element 5. In other words, movement of the outward extending part of the sensor 20 in the direction of the guiding and/or blocking element 5 is prevented or at least reduced. With reference to figures 6 and 7, relative movement of the sensor 20 with respect to the transmitter 1 in the direction of the arrows is prevented or at least reduced. With reference to figure 6, relative movement of the sensor 20 with respect to the transmitter 1 in a direction opposite to the arrows, i.e. when the outward extending part of the sensor 20 moves away from the guiding and/or blocking element 5 is allowed to a small extend, allowing the connected sensor 20 and transmitter to have some relative movement in this direction when attached to the body of the person. Movement in this direction results in the protruding part 24 of the sensor 20 moving away from the first electrical contacts 2 and will thus not result in the first electrical contacts being moved out of their normal position and can thus be allowed.
It is noted that optionally the protruding elements 23 and corresponding recesses 4 as described above may be omitted if the guiding and/or blocking element 5 is provided.
As is shown in the figures the guiding and/or blocking element 5 protrudes with respect to a surface 7 of said transmitter 1, said surface 7 being the surface 7 that comprises said first connecting means 2 or at least the receiving openings of the recesses 2. The surface 7 further comprises said opening 6 via which the protruding part 24 of the sensor 20 is inserted as described above. In particular the guiding and/or blocking element 5 is formed by an extending or protruding part of the upper surface 8 of the transmitter 1, which extends or protrudes beyond the surface 7. The guiding and/or blocking element 5 is thereby located at an upper edge of the surface 7. The guiding and/or blocking element 5 is in this embodiment thus an integral part of the transmitter 1. The upper surface 8 of the transmitter 1 is defined here as the surface that is not in contact with the body of the person in use of the transmitter 1 but opposes the surface that is in contact with the body. The surface 7 of the transmitter is defined here as the front surface of the transmitter 1.
A surface 9 of the transmitter 1 that faces the sensor 20 during connecting and disconnecting and that is adjacent or even in contact with the sensor 20 when connected thereto defines a guiding and/or blocking surface 9 and is adapted to the shape of the surface 25 of the sensor 20 that extends substantially parallel to and is facing towards the guiding and/or blocking surface 9 during connecting to and disconnecting from the transmitter 1 and/or when the sensor 20 is connected to the transmitter 1. In this embodiment, because the sensor 20 has a convex area or surface, the guiding and/or blocking surface 9 comprises a substantially concave area or shape.
Figure 8 shows the transmitter 1 and sensor 20 when these are about to be mechanically connected. In the situation shown in figure 8 the protruding element 24 of the sensor 20 is inserted into the opening 6 of the front surface 7 of the transmitter 1. As is shown in this figure 8, the guiding and/or blocking element 5 has a length that is chosen such that when the protruding part 24 of the sensor 20 extends into a space or area 10 of the transmitter 1 where the first electrical contacts 3 are present the guiding and/or blocking element 5 and in particular the guiding and/or blocking surface 9 thereof contacts the sensor 20, such that the sensor 20 is aligned with respect to the transmitter. As a result of the sensor 20 being aligned with respect to the transmitter when the protruding part 24 of the sensor extends into said area 10, the risk of pressing the first electrical contacts 3 out of their normal position is at least reduced. It is preferred that the guiding and/or blocking element 5 has at least a length that is chosen such that when the protruding part 24 of the sensor 20 is inserted that far into opening 6 of surface 7 that it is able to contact the first electrical contacts 3 and in particular a part 11 thereof that extends into the direction where the protruding part 24 is located in the connected condition the sensor 20 is guided and thereby aligned by the guiding and/or blocking element 5, such that the sensor 20 is at least aligned when it is able to contact the first electrical contacts 3. As a result of the sensor 20 being aligned with respect to the transmitter when the protruding part 24 is able to contact the first electrical contacts 3, the risk of pressing the first electrical contacts 3 out of their normal position is at least reduced. Part 11 in particular extends in an upward direction, i.e. in the direction of the upper surface 8 of the transmitter 1. Part 11 may be referred to as a contact part of the first electrical contacts 3. The length of the guiding and/or blocking element 5 may in particular be substantially equal to or only slightly smaller than the length of the protruding part 24 of the sensor 20. More in particular and as shown in figure 8, the length of the guiding and/or blocking element 5 may be approximately 7 mm, wherein the length of the protruding part 24 of the sensor 20 is about 8.6 mm. The distance between the area 10 where the first electrical contacts 3 are present and the opening 6 of the front surface 7 is about 6.5 mm. Part 11 is located at 1.35 mm from the entrance of area 10, such that the distance between the front part of the guiding and/or blocking element 5 and part 11 of the first electrical contacts 3 is about 13.5 mm. Because the length of the protruding part is about 8.6 mm it is thus already guided and thus aligned by the guiding and/or blocking element 5 before it is able to contact the part 11 of the first electrical contacts. it will be clear for the skilled person that the above described sizes are indicative only and not limiting, as long as the sizes are chosen such that the sensor 20 is already guided and thus aligned by the guiding and/or blocking element 5 before it is able to contact the first electrical contacts 3 of the transmitter 1 during connecting and until the sensor 20 no longer contacts the first electrical contacts 3 of the transmitter during disconnecting.
It is noted that the invention is not limited to the shown embodiments but also extends to variants within the scope of the appended claims.
