[0011] In reference to the figure 1 , the adjustable body monitoring system 1 comprising a main body 2 adapted to measure a physiological quantity of a user. The main body 2 may comprise a control unit, the control unit comprising a microprocessor and a memory. The main body 2 may preferably comprise one or more microneedles, at least one microneedle being configured to measure a body analyte. The microneedles may be covered, at least in part, by an enzyme capable of reacting specifically with a body analyte. A microneedle may also comprise an electrode, making it possible to connect the microneedle to the control unit. The main body may also comprise a display unit, for example a screen, allowing the user to read a value representative of the detection of the body analyst.

[0012] The system comprises a wristband configured to surround a limb of the user. The wristband comprises a first strap 4 mounted on the main body 2 and a second strap 5 mounted on the main body 2. Each of the straps is mounted on the main body at one end of the strap. A strap may be mounted fixed, or by a connection allowing rotation between the main body 2 and the strap.

[0013] The first strip 4 comprises a one-dimensional network of notches 10. A notch 6 may be a recess in the strip or an opening passing through the strip. The one-dimensional network of notches 10 has a pitch p. The step p is defined as the distance along the strap between two notch centers 6. The pitch p is preferably equal between each of the adjacent notches 6 relative to the first strip 4.

[0014] The second strap 5 comprises attachment means 7 configured to be removably fixed in one of the notches 6. The attachment means 7 can be implemented by a projection of a shape complementary to the notch 6, or passing through the notch 6, by a pin-type buckle clasp, by a single or double folding buckle clasp, by a clip clasp, or by any other attachment means known to those skilled in the art.

[0015] The first strip 4 comprises a first face 8. The first face 8 comprises a plurality of markers 9. Each marker 9 is formed by a relief and / or a variation of a color reflected by the first face 8 on the surface of the marker 9 relative to the remainder of the first face 8. A portion of each marker 9 is arranged at a distance less than or equal to the pitch p of a notch 6. This notch 6 is said to be “associated” with said marker 9 and vice versa. A notch 10 may be associated with a single marker 9, or not be associated with a marker, and a marker is associated with a single notch. A portion of the marker 9 associated with a notch 6 is preferably arranged at a distance less than half the pitch p of the associated notch 6, so as to form a first one-dimensional network 11 of markers 9. Two adjacent markers 9 of the first one-dimensional network 11 of markers 9 have different shapes and / or different colors reflected by the first face 8, and / or identical main orientations in the frame of reference of the first strap 4. Thus, the arrangement of the different markers allows a user to precisely control the tightening or loosening of the bracelet surrounding the user's limb. "Main orientation" means the direction of an axis of the marker carried by the largest dimension of the marker.

[0016] The first strap 4 preferably comprises a second face 12, opposite the first face 8. According to the embodiment of the invention, the first face 8 may be the face suitable for use opposite the user's limb, or the face suitable for being visible once the bracelet is adjusted to the user's limbs. Each notch 6 forms, in this embodiment of the invention, an opening passing through the first strap 4. The second face 12 comprising a plurality of markers 9, each marker 9 being formed by a relief or a variation of a color reflected by the second face 12 on the surface of the marker 9, relative to the rest of the second face 12. A part of each marker 9 is arranged at a distance less than or equal to the pitch p of a notch 6 associated with said marker 9, and preferably at a distance less than half the pitch pof the associated notch 6, so as to form a second one-dimensional network 13 of markers. Two adjacent markers 9 of the second one-dimensional network 13 of markers have different shapes and / or different colors reflected by the second face 8, and / or identical main orientations in the reference frame of the first strap 4. Indeed, the tightening of the device 1 can be controlled by the user according to the evolution of the markers 9 of the first face 8, while the loosening of the device 1 can be controlled by the user according to the evolution of the markers of the second face 12 opposite the first face 8.

[0017] A notch 6 may be preferentially associated both with a marker 9 associated on the first face 8 and with a marker 9 associated on the second face 12. Said associated markers 9 then have identical shapes and / or identical colors reflected by the first face 8 and by the second face 12, and / or identical main orientations in the reference frame of the first strip 4.

[0018] The first one-dimensional network 11 of markers and / or the second one-dimensional network 13 of markers has(have) at least two markers 9, the markers 9 having different shapes and / or different colors reflected by the first face 8 and / or by the second face 12, and / or different main orientations in the reference frame of the first strap 4, the markers 9 being arranged periodically in the first one-dimensional network 11 of markers and / or the second one-dimensional network 13. Thus, it is possible to simplify the manufacture of the bracelet by limiting the number of different markers while allowing the tightening and / or loosening of the length of the first strap 4 to be controlled.

[0019] According to a preferred embodiment, the notches and associated markers on each of the faces are identical. This is particularly advantageous because it makes the notches and markers visible to the wearer regardless of how the watch is put on the wrist. Indeed, the wearer must be able to put on his watch whether he is left-handed or right-handed, with the strap therefore oriented differently. This is illustrated in the figures 2 And 3 .

[0020] On the figures 2 And 3the strap 4 of the bracelet 3 is presented in two different ways to the user U. It can be seen that the user U can visualize, depending on the way in which the system is installed on his wrist PO, either the first face 8 or the second face 12 and therefore the markers and notches of the face that they are presented to him in order to correctly install the system on his wrist, that is to say insert the attachment means 7 (a buckle for example) into a notch 6, 10. In particular, on the figure 2 , it is the first face 8 which is presented to the user U while on the figure 3 This is the second side that is presented to the user U. Besides the fact that the bracelet can be easily installed indifferently on the left arm or the right arm, it allows the bracelet to be changed without worrying about any direction of installation. No matter how, the user will be able to install the device on his wrist and will always have the markers and notches in view.

[0021] According to one embodiment, the first and second array of markers 9 are identical, and each marker 9 is attached to the notch 6, 10 with which it is associated, each marker 9 associated with each consecutive notch being different. This is illustrated in the figures 4a, 4b et 4c . on the figure 4a , the notch 6, 10 is rectangular and the associated marker is triangular and is formed by relief (the hatched part represents an opening while the non-hatched part represents a relief). On the figure 4b , notch 6, 10 is rectangular and the associated marker is a circle (the hatched part represents an opening while the unhatched part represents a relief). On the figure 4c , notch 6, 10 is ovoid and the associated marker is a circle (the hatched part represents an opening while the non-hatched part represents a relief). We note that on the figures 4a, 4b et 4c markers are located on either side of notch 6, 10 but we can consider a marker 9 on one side of notch 6, 10.

[0022] According to one embodiment, the first and second marker arrays are identical, and the marker is constituted by a shape given to the notch such that at least each consecutive notch has a different shape. This is illustrated in the figures 4d et 4ewhere it is the shape of the notch as such which makes it possible to distinguish each adjacent one. Those skilled in the art understand that any shape can be given to a notch provided that two adjacent notches are different.

[0023] Additionally, this allows the wearer to properly adjust the bracelet simply.
