    FIELD OF THE INVENTION
    [001] The present invention relates to a detector device and method for clamping and positioning the detector device on a portion of a patient's body. HISTORY OF THE INVENTION
    [002] Psychophysiological parameter detection on the wrist for assessment of mental and physical health status, as described, for example, in Westerink, J. et al.: “Emotion measurement platform for daily life situations” (2009), relies heavily on correct and stable positioning of the detector. Within a human population, wrist circumference and shape vary by a large margin, making it impossible to produce one-size-fits-all wristband detector devices. As an example, the skin conductance detector bracelets. As an example, wristbands with a skin conductance sensor may comprise discrete voltage indicators, vitality wristbands, Q sensors or the like.
    [003] However, on the volar side of the wrist, the skin conductance is lower than in the standard palm position. For pulse blood volume measurements on the volar side of the wrist, the ideal position for the light source and photo detector is in close proximity to an artery. The wrist circumference and shape distribution for the human population cover a wide scope. A wristband device detector, therefore, cannot be a one-size-fits-all piece, but needs expert placement in ideal locations and customization of wristband size and shape. This is very expensive and complex for a conventional product. SUMMARY OF THE INVENTION
    [004] An object of the present invention is to provide a wristband-based detector device that can be easily and effectively customized to individual patient needs.
    [005] This objective is achieved by a detector device, according to claim 1, and by a fixing method, according to claim 11.
    [006] Consequently, a single wristband with integrated sensor(s) can be adjustablely attached to the signal processing unit at both ends. This ensures high accuracy of the position of the sensor(s) on the wristband with respect to the measurement position on the body.
    [007] According to a first aspect, the signal processing unit may comprise a user interface, so that a user or patient wearing the detector device can monitor and/or control the measurement or sensor functions.
    [008] According to a second aspect, which may be combined with the first aspect, the signal processing unit may comprise a data store for storing the measurement results. In this way, measurement results can be monitored for further evaluation of measurement trends.
    [009] According to a third aspect, which may be combined with the first or second aspect, the bracelet may comprise at least one marker for positioning the at least one detector in a predetermined measurement position of a wrist of the body. These facilities correct the positioning and tightness of the detector device wristband. According to an exemplary implementation, the predetermined measurement position can be located on the thumb side of the volar side of the wrist.
    [010] According to a fourth aspect, which can be combined with any of the first to fourth aspects, the bracelet can be adapted to be fastened on both sides of a wrist of the body by the adjustable clasp. This bilateral tightening option ensures correct placement of the electrode(s) and tight, yet fits the wristband snugly.
    [011] According to a fifth aspect, which can be combined with any of the first to fourth aspects, the wristband can be adapted to be inserted into the signal processing unit at one end of the wristband and to be fixed, in an adjustable manner. , on a button portion at the other end of the bracelet. These clamping options provide easy handling during positioning and tightening of the detector device.
    [012] According to a sixth aspect, which may be combined with any of the first to fifth aspects, an end of the bracelet may comprise a segmented portion with a predetermined segmented pattern for removing or adding pieces of the bracelet. The segmented pattern makes it easy to adjust the length of the bracelet by providing predetermined cut segments. The segments can be arranged as a cut pattern, from which the bracelet pieces can be cut, or they can already be separated from each other and can be added or removed piece by piece.
    [013] According to a seventh aspect, which may be combined with any of the first to sixth aspects, the bracelet may comprise at least one cavity to accommodate the at least one electrode. In this way, replacement of a detector (eg electrode) can be made easier by simply pressing on the recoil.
    [014] The realizations of the additional perks are set out below. BRIEF DESCRIPTION OF THE DRAWINGS

    [021] Figure 6 shows a flowchart of a procedure for positioning and tightening the detector device, according to the second embodiment. DESCRIPTION OF PREFERRED ACHIEVEMENTS
    [022] Several embodiments of the present invention will now be described based on a monitoring or detector device for measuring skin conductance in a pulse of a human or animal patient. Of course, the present invention can be used to measure other psycho or physiological parameter(s) either in the same or other portions of the body. It is evident to the person skilled in the art that the detector device, and in particular the wristband, can be adapted to the size and shape of other portions of the body, where the desired parameter can be measured.
    [023] The detector device with its electrodes can be positioned and tightened to the patient and monitors the patient's skin conductance. Skin conductance measurements can be used, for example, to determine if a patient is in a condition where ventilation can or should be changed to determine whether the ventilation change was successful. Of course, it is also possible to use it for other application and measurement parameters.
    [024] Figure 1 shows a schematic hand of a patient with preferred locations for measuring electrodes. In figure 1, a left hand is shown, but the same placement method applies to the right hand as well in a mirrored manner. The quality of a skin conductance signal largely depends on where the electrodes are located. On the volar side of the wrist, skin conductance is lower than the standard palm position. When studying a skin conductance as a function of the exact location on the volar side of the pulse, wide variation is found. Ideal is the region on the thumb side of the volar side of the wrist. The central region shows intermediate skin conductance values, while the little finger side gives the lowest skin conductance values. Since electrodes with a diameter of approximately 1 cm are required, and a wide wristband is not desirable, the ideal measurement positions 110, 120 are shown in figure 1.
    [025] More specifically, one place to get the best signal is on the wrist, with one electrode on the midline of the volar side of the wrist, at a distance of approximately 3-5 cm from the head, and another electrode is positioned close to the first. electrode perpendicular to that line on the thumb side. An ideal distance between the electrodes is 5 mm, with a minimum of 1 mm, and a maximum of 10 mm. This distance is measured from the outer ends of the electrodes at measurement positions 110, 112. Therefore, in an exemplary case, the electrodes may have a standard diameter of approximately 15 mm. So the spacing or distance between electrode centers can be approximately 20 mm.
    [026] In another embodiment, a grounding electrode can be positioned anywhere along the wristband and preferably be much larger than the active electrode. The active electrode is preferably circular, may have a diameter of 1 cm and may be positioned 2 cm from the center of the volar side of the wrist on the thumb side. As another option, the ground electrode can consist of a conductive fabric covering a large portion of the inside of the bracelet.
    [027] Skin conductance can be measured by measuring the voltage drop across two electrodes in a series circuit that contains a stable reference voltage source, a reference resistance that must be stable to thermal fluctuations, and the skin. contact by electrodes made of a conductive and skin-compatible or non-irritating or non-allergic material capable of connecting the electronic/ionic interface with little or no capacitive or resistive interference. The electrodes can be standard skin conductance electrodes as used by skin conductance specialists.
    [028] As another option, the measured skin conductance could be combined with other physiological parameters (such as SpO2, PetCO2, respiratory rate, respiration rate variability, etc.) and/or ventilatory settings to provide a final advice or indication or output. of control. The final recommendation can be in the form of a numerical value (e.g. 1 (e.g. relaxed) to 10 (e.g. serious discomfort)), a traffic light color (red-yellow/orange-green) or instruction message output as “ready to extubate”, “stop SBT”, “start an STB”, “reduce ventilation” or “increase ventilation”. For sure, this is likely to be just one of the possible uses. An alternative focus could be placed on exertion at work, and the prevention of diseases related to prolonged exertion, such as burnout, adrenal fatigue. An additional use could be aggression prevention for psychiatric patients, where the device provides early warning of rising anger...
    [029] Figure 2 shows the implant based on a wrist strap of the detector device with the upper coupling or coating raised. In order to position the electrodes in the above mentioned desired places or wrist measurement positions, the wrist strap 62, as depicted in Figure 2, could be used. This bracelet 62 contains the two electrodes (not shown) and has a length that is adjustable in two different places at both ends. From one side, an appropriate number of segments are removed from a segmented portion 63 (e.g., by cutting) to position the skin conductance sensor electrodes at the positions in Figure 1, and from the other side of the wristband, the excess part near the most ideal hole is cut to fit the bracelet on a person's wrist, so that the skin conductance electrodes are in a firm but comfortable position, touching the entire skin on the volar side of the wrist. Therefore, a procedure can be provided for tightening and positioning a detector wristband for a range of wrist sizes and shapes, whereby the double-sided clasp of the wristband ensures an optimal position of the electrode or sensor, which is maintained during outpatient use. . As an alternative option, the segments of the segmented portion 63
    [030] Skin conductance can be measured by measuring the voltage drop of two electrodes in a series circuit that contains a stable reference voltage generated from a voltage source 65 (e.g. battery) preferably 1.2 V (but not more than 5 V), a reference resistance of typical 3.3 MQ or 10 MQ, and human skin in contact by the two electrodes made of a conductive material, with a diameter of 1 cm. The electrical circuit or connections may be provided on a flexible circuit sheet 64 and may be protected by the casing, on which a user interface 61 may be arranged. The voltage is scaled up and digitized by an analogue-to-digital converter (not shown) with, for example, 12- to 16-bit accuracy, using a stable reference voltage of 3.0V.
    [031] Figure 3 shows a bottom view of a second embodiment with a non-adjustable wristband 62 with segmented pattern 63 at one end and one or two series of attachment holes at the other end, and a signal processing unit 71, which may comprise a user interface and data storage or memory. In addition, indentations 69 are provided on the wristband 62 to accommodate the sensing electrodes. Wristband 62 may be made of elastic with a hollow tunnel for electronic wiring between the sensing electrodes and the signal processing unit 71 with its user interface and data storage.
    [032] Figure 4 shows a perspective view of the detector device, according to the second embodiment, where the user interface 61 is shown with its control elements (for example, mechanical, optical and/or audio indication and/or control or similar). In addition, the button base attachment mechanism 68 is attached to the signal processing unit 71, which can be attached to a pair of holes provided in the wristband 62. In addition, the wristband 62 has a marker 67 which is positioned at the wearer in the middle of the volar side of the wrist. The wrist can then be placed on the table to arrange its position, and the bracelet is clamped on both sides of the wrist by the bilateral clamping mechanism with the segmented pattern 63 and the bracelet holes 62. This ensures an accuracy of at least 5 mm from the position of the detectors 66 on the wristband 62. The improvement could be achieved by providing a table of wrist circumferences and a recommended number of segments to cut or remove from the wristband 62. As an alternative option, the segments of the segmented portion 63 are already they can be separate from each other and can be added or removed piece by piece.
    [033] Figure 5 shows a perspective view of the detector device, according to the second embodiment, after positioning and tightening the wrist. As can be grouped from Fig 5, one end of the bracelet 62 is secured with the buttons of the button base attachment mechanism 68. Of course, another adaptive attachment mechanism with fasteners, flap locks or other locking mechanisms could be used to secure the wristband 62 to the signal processing unit 71. An additional stretch function of the wristband 62 can help provide a good fit. To achieve this, an elastic band can be provided in a tunnel of the wristband 62, which can be there next to a meandering electrical wiring of the flexible circuit sheet 64.
    [034] Figure 6 shows a flowchart of a procedure to position and tighten the detector device, according to the realizations.
    [035] In step S110, the detector electrodes 66 are placed in an ideal position on the volar side of the pulse, for example, as indicated by measurement positions 110, 120 of figure 1. Then, in step S120, the two sides or ends wristband 62 are wrapped around the wrist, and the signal processing unit 71 of the detector device is placed on top of the wrist. In step S130, the ideal wristband size for that person is marked, for example, by adding a mark to the cut pattern 63 and/or the wristband holes 62. Excess material is removed in step S140 with a knife or scissors . As already mentioned above, separate segments could be provided, as in a necklace. The segments may have a small opening on the inner side to allow easy removal: Then step S140 would be modified to remove excess segments or add missing segments needed for optimal size. On one side, the bracelet 62 is then inserted and fixed in the signal processing unit 71 of the bracelet 62 in step S150, as shown in figure 4. Finally, in step S160, the other side of the bracelet 62 is fixed in one or two buttons of the button base attachment mechanism 68, after placing the device on the wrist, as shown in figure 5. The wrist strap can be made of a rubber material, which offers a tight but comfortable fit and stretch ability , so that the detector device can fit well after fixing.
    [036] In summary, the present invention relates to a sensing device and method for tightening and positioning the sensing device with a wristband or wristband for a range of sizes and shapes of wrists or other portions of the body, so that the position of Optimal detection is achieved and maintained during ambulatory use, which provides a two-sided clasp of the bracelet. The wristband has a marker which is positioned by the wearer at a predetermined measurement position, for example in the middle of the volar side of the wrist. The wrist is then placed on the table to arrange its position, and the bracelet is tightened on both sides of the wrist. This ensures an accuracy of at least 5 mm of the position of detectors on the wrist strap.

The invention is not limited to the disclosed embodiments. Upon reading the present disclosure, other modifications will be apparent to those skilled in the art. Such modifications may involve other features, which are already known in the art and which can be used in addition to the features already described here or instead. In particular, other variable attachment mechanisms may be provided on either side or ends of the wristband 62. The detector device with bilateral attachment of the detector wristband may be adapted to measure skin conductance or other parameters in other portions of the body, for example, the ankle(s)...
