Detailed description of the invention
This utility model relates to a kind of for keeping the clip retention of sensor device, and according on the other hand, relates to a kind of device comprising the vital sign for monitoring bio of described clip retention and described sensor device.In the embodiment illustrated hereinafter, described sensor device corresponds to luminescence unit and optical detecting unit.Two parts are all incorporated in clip retention.
Fig. 1 shows according to the device 10 of one side of the present utility model for the vital sign of monitoring bio.In shown monitoring device 10, sensor device is incorporated in clip retention 12, and described clip retention will be supported on biological body office.In the illustration of FIG. 1, sensor device 36 is incorporated in two arms of clip retention 12, and therefore itself invisible from shown visual angle (but only schematically indicating its position by Reference numeral 36 in FIG).Described sensor device comprises radiative luminescence unit, and with after the body part reciprocal action of biology detects the optical detecting unit of launched light at launched light.Specifically, Fig. 1 shows the ear clip by being gripped to people's ear.
Shown device can be used for coming non-invasively measuring blood oxygen saturation (SpO2), heart rate and/or breathing rate by the photo-plethysmographic method summarized in introducing portion.According to the main application of monitoring device of the present utility model be blood oxygen concentration monitoring field.For this reason, luminescence unit along the direction of described tissue with HONGGUANG and infrared spectrum utilizing emitted light.This light organize therewith in blood reciprocal action.After this reciprocal action, catch described light by photodetector (photoelectric detector).The change of blood oxygen saturation can cause the change of blood color, and this can obtain, if especially employ the light of two kinds of different wave lengths by assessing the light detected.
Existing monitoring device in this field has the optics (luminescence unit and optical detecting unit) being fixed to sensor holder usually, and described sensor holder is supported on body office (normally ear or finger).But, for this fixedly, need extra parts, such as covering, screw etc.Usually, described optics to be inserted in sensor holder and to cover by extra cladding element, so that by described sensor element from the sealing of biological body part.This has following shortcoming: need more to bother and therefore more complicated and more expensive packaging technology when manufacturing described device.Such as, and existing clip retention comprises multiple part usually, spring etc.Therefore clean described sensor holder or monitoring device is more difficult to, because dust can enter into the gap between different piece.In addition, the service life of this sensor holder can be limited, because the fault of single part just can destroy this device.Device 10 of the present utility model overcomes these shortcomings by the one-body molded clip retention 12 comprised as shown in Figure 2.
Respectively illustrate this utility model of the example based on ear clip blood oxygen concentration sensor below, described ear clip blood oxygen concentration sensor is intended to be used in Ren Erchu.But this utility model is not limited to use in this application.Other application can comprise for referring to that people place or people's other body part any (such as toe, nose or nostril) place support the clip retention of sensor device.Except blood oxygen concentration, also may from organize reciprocal action after detect light-output breathing rate and/or heart rate.
Be integrated according to clip retention of the present utility model, be namely made up of single entirety, or in other words, be unitary elements.Clip retention 12 is formed by the material of elastically deformable, and described material is out of shape by deformation force is applied to it.When discharging described power, clip retention 12 returns to its original shape (relaxed state).Clip retention 12 comprises two arm section 14a and 14b, its each substantially along the longitudinal axis 15a and 15b extend.Each arm section comprises actuation part 16, coupling part 18, hinge fraction 20 and contact portion 22.Clip retention 12 also comprises the bridge section 24 of connection two arm sections 14a, 14b.Bridge section 24 is connected to described two arm sections at coupling part 18 place of two arm sections 14a, 14b.If actuation force to be applied to the actuation part 16 of two arm sections 14a, 14b, then described arm section is pivoted relative to each other around the pivotal point (pivot axis) in the region of bridge section 24.In other embodiment of the present utility model, described pivotal point also can in other position.
If bridge section 24 is provided for the functions of pivoting making two arm section 14a, 14b pivotables when performing actuation force to actuation part 16.Described bridge section forms bridge joint hinge.For this reason, make use of the elastic deformability of described material.Preferably, bridge section 24 is with the form molding of circle segment, and its direction along contact portion 22 is open.This allow to distribute rightly be applied to two actuation parts actuation force to provide hinge function.In addition, the region that can receive body part increases.
When actuation force is applied to actuation part 16, clip retention 12 is in release conditions, and contact portion 22 separately.In other words, arm section 14a, 14b are pivoted relative to each other, because the elastic deformation due to actuation force of bridge joint hinge.Then body part can be received between arm section, or more specifically, is received between its contact portion 22.Usually, described actuation force is by using the people of monitoring device or by monitoring device being applied to patient doctor with it or nursing staff is applied to actuation part 16.If the body part of biology to be received between arm section 14a, 14b and release to the actuation force on actuation part 16, then perform clamping force via two contact portions 22 to described body part, this deformable material due to clip retention 12 is wanted to return to its original shape and is caused.Then described clip retention clamps or clips to described body part.
Usually, different people (adult, baby etc.) has the ear-lobe of different size.Therefore, when clip retention 12 is applied to ear-lobe, it can not guarantee the parallel alignment of the contact portion 22 of arm section usually.But this parallel alignment of contact portion 22 may be necessary, to guarantee good optical path and sensor reading accurately.Optical pickocff is interfered photo effect usually.When based on when carrying out transmissivity measurement through body part to the light of another arm section 14b from an arm section 14a (or contact portion 22), this is even more important.This utility model by providing hinge fraction 20 and overcoming this defect between the actuation part 16 and contact portion 22 of two arm sections 14a, 14b.Therefore, the luminescence unit be incorporated in the contact portion 22 of the first arm section 14a or supported by it aligns with the optical detecting unit supported in the contact portion 22 being incorporated into the second arm section 14b or by it.Hinge fraction 20 provides the motility that contact portion 22 and actuation part 16 are pivoted relative to each other.Therefore, it is possible to make two contact portions 22 adjust its orientation (relative to each other and relative to body part) based on the shape of the body part between it and/or thickness, namely each contact portion 22 deflects into separately and contacts with body part.On the one hand, the arm hinge in hinge fraction 20 allows the body part of the different size between compensation two arm sections 14a, 14b.On the other hand, comfortable wearing degree can be improved, because the power being applied to body part is equally distributed.
In general, clip retention 12 because of herein is provided three pivotal points 25, two in arm section (hinge fraction 20) and one in bridge section 24.These pivotal points 25 also can be called virtual pivot.Mechanical stress caused by open and close clip retention 12 can be dispersed on three pivotal points 25.
Fig. 3 a and 3b respectively illustrates the execution of actuation force 26 on the actuation part of two arm sections and power distribution, and the stress namely in material, which results in the elastic deformation of two arm sections and bridge section.
Can find out in fig. 3 a, the applying of actuation force 26 result in the distortion of bridge section (comparing the power distribution in the region of bridge section), arm section is separated, is namely pivoted relative to each other.Fig. 3 a shows release conditions.Described bridge section provides hinge function.Hinge fraction in described arm section is stressless.When discharging actuation force 26, arm section body part in-between performs clamping force 28.
Fig. 3 b shows clamped condition, and wherein body part (not shown) is received between described two arm sections.Can find out, described deformable material is also subject to stress in the hinge fraction of arm section.Compared with there is the design of two rigid arm sections, according to sensor holder of the present utility model because herein is provided the parallel alignment more or less of two arm sections.Which results in the alignment (from luminescence unit to optical detecting unit) of optical path.Therefore, the impact that can affect the surround lighting of measurement quality negatively can be reduced.In addition, and be applied to by all stress compared with a single pivoting member, described material owing to being subject to less stress by stress dispersion on three different pivotal points.As a result, can material aging be reduced, and the service life of parts can be increased.In addition, make it possible to provide higher users'comfort due to the clamping force more balanced in whole contact portion.
Fig. 4 illustrates in greater detail the contact portion 22 of the arm section of clip retention with profile.Sensor holder before this has usually needs independent/extra cladding element to carry out the shortcoming of covering sensor device relative to tissue.This covers separately has following shortcoming: assembling process is more complicated, and therefore more expensive, and the clean of sensor holder becomes more difficult, because dust may penetrate in the small―gap suture between different piece.This problem makes chamber 32 overcome with the barrier film 30 be separated with the contact surface 34 that the tissue of biology contacts by this utility model by providing.Chamber 32 is used as assembling space, and is received in wherein at least partially by sensor device 36.Usually, sensor device 36 (or part of sensor device) is connected to external process devices or energy source by cable channel 38.Cable channel 38 extends generally through whole arm section, and is connected to the cable originating in actuation part office.
