(Embodiment)
FIG. 1 is a diagram showing a configuration of a biological information measuring device according to the present embodiment. FIG. 1A shows a plurality of protective caps and a main body separately arranged, and FIG. It is a figure which shows a mode that the biosensor was mounted | worn. In the following description, an example of an apparatus for measuring blood sugar level by spotting a subject's blood on a biosensor will be described. However, the present invention is not limited to this, and the body fluid of the subject is spotted on the biosensor. If information can be measured, it can be similarly realized.

  As shown in FIG. 1, the biological information measuring device of the present embodiment includes a main body 2 having a sensor mounting portion 1 and a protective cap 3 that detachably covers the sensor mounting portion 1 of the main body 2. The protective cap 3 includes a sensor insertion port 5 for inserting the biosensor 4 into the sensor mounting portion 1, and a wall portion for guiding the biosensor 4 inserted into the sensor insertion port 5 toward the sensor mounting portion 1. 14 (see FIG. 3). Furthermore, the protective cap 3 has a sensor holding part 6 that can hold the biosensor 4 in a state of being inserted into the sensor insertion port 5. The main body 2 includes an input unit 7 capable of inputting measurement date and time, information on the person to be measured, and the like, and a display unit 8 for displaying contents input by the input unit 7 and measurement results.

  Although not shown, the main body 2 incorporates a battery that drives each component of the main body 2. The main body 2 is driven by this battery, and a blood glucose level measuring unit for measuring a blood glucose level from the blood of the measurement subject attached to the biosensor, and a memory for storing data measured by the blood glucose level measuring unit And a data transmission / reception unit for communicating the measurement data stored in the memory with an external device or the like.

  Here, an outline of blood glucose level measurement using this biological information measuring apparatus will be described. In the present invention, it is assumed that, in a medical institution, a staff has one biological information measuring device and measures a plurality of measured persons one after another. This is a situation that can occur in a hospital outpatient laboratory, in a hospital ward, or on a single floor.

  First, the staff attaches the protective cap 3 to the main body 2. Next, the biosensor 4 is inserted from the sensor insertion port 5 of the protective cap 3 and mounted on the sensor mounting portion 1 of the main body 2 to prepare for measurement as shown in FIG. For example, the blood sugar level measurement unit in the main body 2 detects that the biosensor 4 is mounted on the sensor mounting unit 1 and automatically enters a measurement standby state, and blood is spotted on the tip of the biosensor 4. Work to wait.

  When the preparation of the biological information measuring device is completed in this way, the staff or the subject himself / herself punctures the subject's fingertip with a puncture device or the like, and squeezes a small amount of blood from the skin. Then, the fingertip punctured by the measurement subject is brought into contact with the tip of the biosensor 4, and the squeezed blood is spotted on a spotting portion (not shown) of the biosensor 4.

  When the blood sugar level measuring unit detects that blood has been spotted on the spotting part, the blood sugar level measuring unit automatically measures the blood sugar level. The measured blood glucose level is sent to the memory and stored together with the information on the person to be measured input from the input unit or the like. At the same time, it is also sent to the display unit for display.

  When the staff sees the display unit and confirms that the blood glucose level has been measured normally, the staff removes the protective cap 3 and the biosensor 4 from the main body 2 and discards them in the disposal BOX or the like. At this time, the biological information measuring apparatus of the present embodiment is configured such that the protective cap 3 and the biosensor 4 are removed together. The operation at the time of removal will be described later.

  Thereafter, the staff attaches the protective cap 3 and the biosensor 4 to the main body 2 again in order to measure the next person to be measured. The above is the outline of measuring a plurality of subjects continuously.

  Here, attention is focused on spotting blood by bringing the fingertip of the measurement subject into contact with the biosensor 4. The biological information measuring device is held by the staff, and the biological information measuring device is brought close to the fingertip of the person to be measured so that the fingertip of the person to be measured and the biosensor 4 are in contact with each other. Move closer to the measuring device.

  However, when the staff is performing the measurement in the above-described situation, the relative position of the measurement subject's fingertip and the biosensor 4 is easily shifted due to a sudden balance, and the measurement subject's fingertip is positioned at the tip of the biosensor 4. May come out of contact with the main body 2 of the biological information measuring device. Then, since the fingertip of the measurement subject has already squeezed out blood by puncture or the like, if the main body 2 is in an exposed state, the exposed blood may adhere to the main body 2.

  When measurement is continued for the subsequent measurement subject while the blood is attached, the relative position of the measurement subject's fingertip and the biosensor 4 is similarly shifted so that the measurement subject's fingertip is separated from the wall surface of the main body 2. When contact is made, there is a possibility that the blood that has just adhered will adhere to the subject. At this time, since the measurement subject is in a state where the surface of the skin is damaged by puncture or the like, it is extremely dangerous if blood adhering to the surface enters the body.

  Therefore, the biological information measuring apparatus of the present embodiment includes a protective cap 3 that can be replaced for each measurement, and this protective cap 3 covers the wall surface of the surrounding main body 2 including the sensor mounting portion 1. I have to. By doing in this way, even if the fingertip of the person to be measured contacts the biological information measuring device, it is on the protective cap 3 that blood adheres. And since this protective cap 3 is replaced whenever the person to be measured changes, it is possible to prevent the adhesion of blood to other persons to be measured as described above.

  In order to obtain such an effect, the protective cap 3 must be formed so as to cover the range of the wall surface of the main body 2 that can be touched by the fingertip of the person to be measured. In the present embodiment, as shown in FIG. 1B, the range visible from the side surface on the biosensor 4 side is covered, and the end portion extends to the vicinity of the display unit 8.

  However, the range to be covered is an example, and a person skilled in the art can appropriately change the range as necessary. For example, the display unit 8 may be covered, the input unit 7 may be covered, or the end of the main body 2 opposite to the side where the biosensor 4 is mounted, that is, the entire main body 2 may be covered. good.

  At a minimum, it is necessary to cover the wall surface of the main body 2 around the sensor mounting portion 1. In addition, in a state where the protective cap 3 and the biosensor 4 are mounted on the main body 2, at least the spotted portion at the tip of the biosensor 4 must be exposed from the protective cap 3.

  Next, the specific structure of the protective cap 3, which is one of the features of the present embodiment, will be described in more detail with reference to FIGS. FIG. 2 is an enlarged view of the vicinity of the sensor mounting portion 1 of the main body 2 and a view showing the protective cap 3. FIG. 3 is a cross-sectional view of the inside of the protective cap 3 as viewed from the opening at the other end of the sensor insertion port 5. FIG. 4 is a cross-sectional view illustrating a state when the protective cap 3 and the biosensor 4 are attached to the main body 2. FIG. 5 shows an enlarged cross-sectional view of the protective cap 3 in the vicinity of the sensor insertion opening 5 and a diagram showing a state when the biosensor 4 is inserted into the sensor insertion opening 5. FIG. 6 is a diagram illustrating a state in which the protective cap 3 is pinched and a state in which the biosensor 4 is held by the sensor holding unit 6 at that time.

  First, the protective cap 3 is made of a flexible material, and both surfaces of the protective cap 3 facing the biosensor 4 are used as the sensor holding unit 6 described above. As shown in FIG. 2, the sensor holding unit 6 is provided with a pad 9 at a portion in contact with the biosensor 4 so as not to slip when the biosensor 4 is sandwiched. When the surface of the sensor holding part 6 of the protective cap 3 is difficult to slip or when such a material is applied, the pad 9 does not have to be provided as shown in FIG.

  Alternatively, instead of the pad 9, it may be processed so that the biosensor 4 does not slip by forming several grooves in a portion in contact with the biosensor 4 or roughening the surface.

  Further, the protective cap 3 has notches 10a and 10b provided on the side surface of the opening opposite to the sensor insertion port 5, and an engaging recess in one or both of the notches 10a and 10b ( In this embodiment, they are provided in the vicinity of both of the notches 10a and 10b, which are referred to as engagement recesses 11a and 11b, respectively, and an engagement protrusion (similarly) that engages with the engagement recess as shown in FIG. The main body 2 is provided with engaging protrusions 12a and 12b.

  Note that the back surface of the sensor holding portion 6 of the protective cap 3, that is, the outer surface of the protective cap 3 located on the opposite surface of the sensor holding portion 6, serves as a guide when the staff puts a finger and removes the protective cap 3. A grip 13 is provided so as to prevent a finger from slipping occasionally. The grip 13 may be a plurality of rod-shaped protrusions as shown in the figure, but any gripper that is processed on the surface so that the finger does not slip, such as a circular protrusion, may be used. good. If the grip 13 is provided on the back surface of the sensor holding part 6 in this way, the point of action of the force when the staff attaches the finger is in the vicinity of the sensor holding part 6, thereby holding the biosensor 4 more reliably. Is possible.

  Next, the sensor insertion port 5 provided at the tip of the protective cap 3 will be described with reference to FIGS. FIG. 3A shows the inside of the protective cap 3 as viewed from the direction of the opening at the other end of the sensor insertion port 5, that is, the notches 10a and 10b. And FIG.3 (b) has shown the cross-sectional perspective view cut | disconnected by the AA cross section in Fig.3 (a).

  As shown in FIG. 3, a wall portion 14 is formed inward from the sensor insertion opening 5. The wall 14 has two major roles. The first is a guide function for guiding the inserted end of the biosensor 4 toward the sensor mounting portion 1 of the main body 2 when the biosensor 4 is inserted into the sensor insertion port 5. This is particularly effective when there is a gap between the sensor insertion opening 5 and the sensor mounting portion 1 when the protective cap 3 is mounted on the main body 2.

  If the biosensor 4 is inserted into the sensor insertion port 5 with an angle in the vertical or horizontal direction with respect to the line direction connecting the sensor insertion port 5 and the sensor mounting unit 1, the sensor mounting unit 1 The biosensor 4 is continuously inserted toward the deviated position. However, the presence of the wall portion 14 prevents the end portion of the inserted biosensor 4 from reaching the wall portion 14. When the end portion of the biosensor 4 comes into contact with the wall portion 14, resistance is generated in the hands of the staff holding the biosensor 4 and the biosensor 4. At that time, the elastic biosensor 4 bends and its end faces toward the sensor mounting portion 1. Alternatively, the staff feels resistance and changes the angle at which the biosensor 4 is inserted, so that the end portion is directed toward the sensor mounting portion 1. In this way, the portion of the biosensor 4 that is attached to the sensor attachment portion 1 is guided to the sensor attachment portion 1.

  In order to obtain such an operational effect, the wall portion 14 needs to extend from the sensor insertion port 5 toward the sensor mounting portion 1. It is more effective to make the length longer as the gap between the sensor mounting portion 1 and the sensor insertion port 5 is larger. Or what is necessary is just to make it the length which just contacted the wall part 14 and the sensor mounting part 1, or was extended to the front irrespective of the magnitude | size of a clearance gap. On the other hand, the minimum length is defined by the size of the opening of the sensor insertion slot 5. That is, since the degree of freedom of the angle of the biosensor 4 with respect to the sensor insertion port 5 increases as the opening becomes larger, it is necessary to lengthen the wall 14 in order to regulate the direction.

  FIG. 4 illustrates a state of mounting the biosensor 4 described above. FIG. 4A shows a state in which the biosensor 4 starts to be inserted into the sensor insertion port 5, and FIG. 2 shows a state in which the sensor is mounted on the sensor mounting unit 1. As shown in FIG. 4A, even when the biosensor 4 has a large angle with respect to the sensor insertion port 5 at first, the biosensor 4 is guided to the wall portion 14 as shown in FIG. It is attached to the sensor attachment part 1.

  The second role of the wall portion 14 is to prevent blood flowing through the biosensor 4 from reaching the sensor mounting portion 1. That is, blood is blocked by the protective cap 3 that is exchanged for each measurement, thereby preventing blood from adhering to the sensor mounting portion 1 that cannot be easily exchanged. For example, when a large amount of blood comes out, for example, because the person to be measured greatly scratches the fingertip, the biosensor 4 does not fit in the spot of the biosensor 4 when it is spotted on the biosensor 4. May flow through.

  At this time, if the living body information measuring device is tilted and positioned below the fingertip of the person to be measured, blood overflowing from the tip portion flows through the biosensor 4 toward the sensor mounting portion 1. The wall portion 14 is formed so that the blood stops at the wall portion 14 of the sensor insertion port 5. Specifically, as shown in FIG. 5A, the end opening diameter of the wall 14 opposite to the sensor insertion port 5 is set to be substantially the same as or slightly larger than that of the biosensor 4. The opening diameter of the sensor insertion port 5 may be substantially the same as or slightly larger than that of the end portion of the wall 14, but it is easy to accept the biosensor 4 as shown in FIG. Thus, when the opening diameter is increased, the wall portion 14 is inclined (tapered) from the sensor insertion port 5 toward the other end.

  If the wall portion 14 is configured in this manner, as shown in FIG. 5 (b), the tip of the blood 15 advances by the surface tension and the degree of blood adhesion in the tip of the wall portion 14 or in the middle of reaching the tip. Stops and does not flow toward the sensor mounting portion 1 inside the wall portion 14. Furthermore, if the surface of the wall portion 14 is subjected to a hydrophobic treatment, blood can be prevented from flowing further into the wall portion 14 near the sensor insertion port 5.

  Fig.6 (a) is a figure which shows the state which applied the pressure to the grip 13 of the upper and lower surfaces of the protective cap 3 shown in FIG. This occurs when the staff puts one hand from the side of the protective cap 3 between the thumb and the other finger and pinches it with the thumb and the other finger. As shown in FIG. 6A, when the grips 13 on both the upper and lower sides of the protective cap 3 are pressurized from the outside, the notches 10a and 10b provided on the side surfaces start, and the side surfaces of the protective cap 3 bend outward. . As a result, the sensor holding portions 6 positioned on the upper and lower surfaces of the protective cap 3 bend inward.

  At this time, since the notches 10a and 10b are the starting points and the side surfaces of the protective cap 3 are bent outward, the engaging recesses 11a and 11b provided in the vicinity of the notches 10a and 10b are also moved to the outside. The engagement with the engagement projections 12a and 12b provided on the main body 2 is released. Then, since the engagement for fixing the main body 2 and the protective cap 3 is lost, the protective cap 3 can be detached from the main body 2 freely.

  If the material of the protective cap 3 includes an elastic material that returns to its original shape, and the pressure on the grip 13 is stopped even after the grip 13 is pressed and the side surface of the protective cap 3 is bent outward. The side surface may be restored to its original shape, and the engagement recesses 11a and 11b may return to the positions where they engage with the engagement projections 12a and 12b, so that the protective cap 3 can be attached to the main body 2 again. .

  FIG. 6B is a diagram showing a state in which the biosensor 4 is held by the sensor holding unit 6 when the protective cap 3 is removed. For the sake of understanding, the biosensor 4 is shown so that the biosensor 4 can be seen through the protective cap 3. However, as shown in FIG. Further, the biosensor 4 located inside the protective cap 3 may be seen through.

  As shown in FIG. 6 (b), when the protective cap 3 is removed together with the biosensor 4, the tip of the biosensor 4 spotted with blood is located completely inside the protective cap 3, and the protective cap 3 What is exposed from 3 is the portion mounted on the sensor mounting portion 1 of the main body 2 and its periphery.

  For this purpose, the dimensions of the protective cap 3 are mainly determined by the dimensions of the biosensor 4. That is, when the protective cap 3 and the biosensor 4 are attached to the main body 2, the spotted portion at the tip of the biosensor 4 is exposed from the protective cap 3, and when removing the protective cap 3 and the biosensor 4, The spotted portion of the biosensor 4 only needs to satisfy a relationship that fits in the protective cap 3.

  FIG. 6C is a diagram showing the positional relationship between the main body 2, the protective cap 3, and the biosensor 4 for determining the dimensions described above. If the opening end position of the protective cap 3 when the protective cap 3 is mounted on the main body 2 is the BB surface, the distance La from the BB surface to the end of the protective cap 3 on the sensor insertion port 5 side is: It must be shorter than the distance Lb from the BB surface to the end of the main body 2 on the sensor mounting portion 1 side plus the length Lc from the end of the sensor mounting portion 1 to the tip of the biosensor 4. This is because the spotted portion provided at the tip of the biosensor 4 must be exposed in order to spot the blood of the measurement subject.

  Furthermore, the distance Lb from the BB surface to the end of the main body 2 on the sensor mounting portion 1 side must be longer than the distance Ld from the end of the protective cap 3 on the sensor insertion port 5 side to the tip of the biosensor 4. Don't be. This is because the tip of the biosensor 4 is placed in the protective cap 3 when the protective cap 3 is removed and slid and the sensor holding part 6 provided near the opening end of the protective cap 3 holds the biosensor 4. Is necessary.

  Note that, as described above, even if the BB surface is set to a position that covers not the illustrated display unit 8 but the input unit 7, the display unit 8, and eventually the end of the main body 2, these distance conditions Anything that satisfies the above is acceptable.

  Next, the shape near the sensor mounting portion 1 of the main body 2 will be described with reference to FIG. FIGS. 7A, 7B, and 7C are enlarged views of the vicinity of the sensor mounting portion 1 of the main body 2. FIG. FIG. 7A has a guide portion 16 at the upper part of the sensor mounting portion 1 as in the other drawings. Although not shown, there is a similar guide portion 16 at a position facing the back side of the main body 2. The guide portion 16 is formed so as to be positioned immediately below the sensor holding portion 6 and the grip 13 when the protective cap 3 is attached to the main body 2. When the grip 13 is pressed from both sides by a staff finger, a space is created between the protective cap 3 and the wall surface of the main body 2 by the guide portion 16 so that the grip 13 is pushed downward (main body 2 side). .

  When the staff presses the grip 13 from both sides, the protective cap 3 is pushed downward by the amount created by the guide portion 16, and the entire protective cap 3 bends. Then, the side surface of the protective cap 3 is bent outward from the notches 10a and 10b, the engagement concave portions 11a and 11b and the engagement convex portions 12a and 12b are disengaged, and the protective cap 3 can be removed. In this state, the staff slides the protective cap 3 by sliding the grip 13 forward (in the direction of the sensor mounting portion 1). At this time, the guide unit 16 also functions as a guide for guiding the staff's finger in the sliding direction. Since this guide portion 16 is formed up to the sensor mounting portion 1, the finger that has been slid easily holds the biosensor 4 as it is.

  FIG. 7B shows another form of the guide portion 16, and a similar dent portion exists on the back surface. 7A differs from that shown in FIG. 7A in that the drop from the main body 2 to the guide portion 16 is not a step but an inclination. With such a shape, not only the same effect as the shape of FIG. 7A described above can be obtained, but also the staff finger can be more easily guided to the sensor mounting portion 1 and the biosensor 4 can be easily sandwiched. Become.

  FIG. 7C shows a shape in which the sensor mounting portion 1 is further protruded forward in accordance with the shape of the guide portion 16 in FIG. Thereby, the finger of the staff guided to the sensor mounting portion 1 by the guide portion 16 can more easily pinch the biosensor 4 more reliably. It should be noted that the same effect can be obtained by combining the shape of the guide portion 16 of FIG. 7B with the protruding shape of the sensor mounting portion 1 as shown in FIG. 7C.

  Finally, how the protective cap 3 and the biosensor 4 are removed after measuring the blood glucose level in the biological information measuring apparatus according to the present embodiment will be described with reference to FIG. First, the staff places one hand from the side of the protective cap 3 and sandwiches the grips 13 provided on both sides of the protective cap 3 with the thumb and other fingers. Then, a force is applied to the fingers sandwiching the grip 13, and the grip 13 is pushed down to the main body 2 side. Then, the engagement concave portions 11a, 11b and the engagement convex portions 12a, 12b are disengaged, and the protective cap 3 can be removed (FIG. 8 (a)).

  When the protective cap 3 is slid forward (in the direction of the sensor mounting portion 1) in the state as it is, the biosensor 4 does not move from the position as it is, and only the protective cap 3 is displaced. This is because the biosensor 4 is sandwiched between electrodes (not shown) in the sensor mounting portion 1, and the force is generated by a frictional force generated between the biosensor 4 and the sensor insertion port 5 of the protective cap 3. This is because the biosensor 4 is larger than the force for pulling out the biosensor 4 from the sensor mounting portion 1, and therefore the biosensor 4 does not attempt to be detached from the sensor mounting portion 1.

  When the end of the protective cap 3 reaches the sensor mounting portion 1 as shown in FIG. 8B, the staff's finger further pushes down the grip 13 and holds the biosensor 4 via the sensor holding portion 6. I can do it. As a result, the force generated by the staff's finger is directly transmitted to the biosensor 4. Then, it becomes possible to apply a force larger than the force for holding the biosensor 4 by the electrode of the sensor mounting portion 1 described above, thereby bringing the protective cap 3 and the biosensor 4 together as shown in FIG. Can be removed. The staff only has to discard the protective cap 3 and the biosensor 4 as they are to the disposal BOX or the like.

  Thus, since the tip side where the blood of the removed biosensor 4 is spotted is covered with the protective cap 3, the measurement subject and the staff do not touch the blood attached to the removed biosensor 4, Can be discarded.

  As described above, according to the biological information measuring device of the present embodiment, the main body having the sensor mounting portion, the sensor mounting portion of the main body, and the wall surface of the main body at least on the surface provided with the sensor mounting portion. A protective cap that detachably covers the whole, the protective cap including a sensor insertion port for inserting a biosensor into the sensor mounting portion, and the sensor mounting portion for inserting the biosensor inserted into the sensor insertion port. Because it has a wall part that guides in the direction of, cover the area to which the body fluid of the person to be measured can adhere with a protective cap, and replace this protective cap so that the body fluid does not adhere to other persons to be measured I can do it.

  In addition, the protective cap has a sensor holding part that can hold the biosensor inserted in the sensor insertion port, so when replacing the protective cap, hold the biosensor in the sensor holding part and remove it together. Therefore, it is possible to increase the work efficiency compared to removing the sensor holding part and the biosensor separately.

  In particular, since the place where the blood of the biosensor adheres is covered and removed by the sensor holding part, the concern for preventing adhesion to the surroundings can be relaxed, and the working efficiency is improved.

The biological information measuring apparatus according to the present invention comprises a body having a sensor mounting portion for mounting the biosensor, of the body wall, and a protective cap covering a portion of the wall containing the sensor mounting portion, the protective cap is formed biosensor is penetrable through hole the protective cap, through hole, a sensor insertion port to insert the biosensor a one opening of the through hole, the sensor mounting an other opening When the protective cap is attached to the main body, the through hole is inserted into the sensor when the protective cap is attached to the body, which is defined by the opposite opening located on the part side and the wall part between the sensor insertion opening and the opposite opening. The biosensor inserted from the mouth is guided in the direction of the sensor mounting portion by passing through the opposite opening through the wall, and the opening diameter of the sensor insertion opening is larger than the opening diameter of the opposite opening. like Since, useful as a device or the like that body fluid of the subject is attached to the other of the subject without measuring the multiplayer.
