Description

  The present invention relates to a biological sample measuring apparatus for measuring biological samples such as blood glucose level and lactic acid level.

A conventional biological sample measuring apparatus has the following configuration.
That is, the conventional biological sample measuring apparatus includes a main body case having a long second direction (longitudinal direction) perpendicular to the first direction with respect to the first direction (width direction, short direction), and the second direction of the main body case.

  In the above configuration, the measurer first grasps the opposite side (second end side) of the first end of the main body case, and measures the ID data of the measurer, patient ID data, sensor ID data by the data reading unit. To read. Next, the measurer attaches the sensor to the sensor attachment unit, and then punctures the patient's finger. As a result, for example, blood sugar level is measured by introducing blood or the like that has oozed from the patient's finger into the sensor.

JP-T-2002-521692

However, the conventional biological sample measuring apparatus has the following problems.
That is, in the above conventional configuration, the sensor mounting portion is provided on the first end side of the main body case, but the display portion is also provided on the first end side. As a result, the first end side was heavier than the second end side, and the weight balance of the device was biased.

  Therefore, it becomes difficult to accurately contact the sensor mounted on the first end side with the puncture portion of the patient. For this reason, the measurer operates the sensor so as to scoop out blood that has exuded from the puncture portion of the finger, or operates the sensor so as to press the blood exuding from the puncture portion. There is a case. In such a case, for example, the blood glucose level may not be measured appropriately, so that the sensor needs to be replaced and the measurement operation described above must be repeated again. Therefore, the conventional configuration is inconvenient for the measurer.

  Accordingly, an object of the present invention is to provide a biological sample measurement device that is easy to use.

  In order to achieve the above object, the biological sample measurement device of the present invention includes a main body case, a data reading unit, a sensor mounting unit, a display unit, and a finger contact groove. The main body case has a long second direction orthogonal to the first direction with respect to the first direction. The data reading unit is provided on the first end side serving as one end in the second direction in the main body case. The sensor mounting portion is provided on the second end side which is the other end in the second direction in the main body case. The display unit is provided on the surface of the main body case on the first end side. The finger contact groove is provided closer to the sensor mounting portion than the display portion on the back side of the main body case, and is formed along the first direction of the main body case. The weight on the second end side from the finger contact groove in the main body case is lighter than the weight on the first end side from the finger contact groove in the main body case.

  Here, the first and second directions are, for example, a width direction (short direction) and a vertical direction (longitudinal direction) perpendicular to this when using a biological sample measuring apparatus having a substantially rectangular parallelepiped shape in hand. Means.

Here, the sensor mounting portion is provided on the opposite side (second end side) to the display portion in the main body case, and the finger contact groove along the first direction from the display portion on the back surface of the main body case to the sensor mounting portion side. Is provided. Then, the weight on the second end side of the main body case from the finger pad groove is made lighter than the weight on the first end side of the main body case with reference to the position of the finger contact groove.
As a result, the operation of bringing the sensor attached to the sensor attachment portion into contact with the puncture portion of the patient holds the second end side of the lighter body case while holding the first end side of the heavy body case. This can be performed stably by approaching the puncture portion of the patient. As a result, the operation of bringing the sensor into contact with the puncture portion of the patient can be easily performed in a stable state. Therefore, the sensor is not operated so as to scoop the blood in the puncture part or the sensor is operated so as to be pressed against the blood in the puncture part. For example, the blood sugar level can be measured in a short time. An easy-to-use biological sample measuring apparatus that can be appropriately implemented can be obtained.

  According to the present invention, for example, it is possible to obtain an easy-to-use biological sample measuring apparatus capable of appropriately measuring blood glucose levels in a short time. Such an effect should be very highly evaluated in a department that needs to measure biological samples appropriately from many patients in a short time, such as a hospital.

  As shown in FIGS. 2 to 5, the main body case 1 has a shape in which the longitudinal direction (second direction) is longer than the width direction (first direction). On one end side (first end side) in the second direction of the main body case 1 (right side in FIG. 2), for example, a data reading unit 3 such as a barcode reader is provided. Furthermore, a sensor mounting portion 4 is provided on the other end side (second end side) (left side in FIG. 2) of the main body case 1 in the second direction.

  Further, as shown in FIGS. 2 and 3, a vertically long rectangular display unit 5 is provided on the surface of the main body case 1 on the first end side. Further, as shown in FIGS. 4 and 5, a measurer's finger abuts along the width direction of the main body case 1 from the display portion 5 on the back side of the main body case 1 to the sensor mounting portion 4 side. A finger contact groove 6 is provided.

  In the present embodiment, in the main body case 1, the weight from the finger contact groove 6 to the second end side (sensor mounting portion 4 side) and the weight from the finger contact groove 6 to the first end side (display portion 5 side) are used. It is lighter than that. This is because a relatively heavy configuration such as the display unit 5 is disposed on the first end side from the finger contact groove 6 of the main body case 1.

  Returning to FIG. 2 and FIG. 3, the description is continued. The operation unit 7 is disposed at a position on the front surface side corresponding to the finger contact groove 6 provided on the back surface side of the main body case 1. In addition, a sensor discharge lever 9 for discharging the sensor 8 (see FIG. 13) to the outside of the sensor mounting unit 4 is disposed between the operation unit 7 and the sensor mounting unit 4.

  As shown in FIGS. 4 and 5, a battery cover 10 that is opened and closed when the battery 15 is inserted and removed is disposed between the finger contact groove 6 and the data reading unit 3 on the back surface side of the main body case 1. ing. Inside the battery lid 10, a battery storage unit in which the battery 15 is loaded is provided. Between the battery lid 10 and the data reading unit 3, rubber legs 11 for preventing slipping are disposed. Further, similarly, a rubber leg 12 for preventing slipping is disposed between the finger contact groove 6 and the sensor mounting portion 4.

  In the above configuration, in the present embodiment, as shown in FIG. 4, the gravity center position 1 </ b> A of the main body case 1 is set from the finger contact groove 6 to the data reading unit 3 side (first end side).

  As is clear from FIG. 3, the horizontal width of the main body case 1 is the largest in the display portion 5 and gradually decreases from the display portion 5 toward the sensor mounting portion 4 side. That is, the lateral width on the sensor mounting portion 4 side is set to be the smallest.

  FIG. 6 is an electrical control block diagram of the biological sample measurement device. As is well known, a connection terminal 2 a to the cradle 2, a data reading unit 3, a sensor mounting unit 4, and a display unit 5 are connected to the control unit 13. However, a measurement unit 14 is provided between the sensor mounting unit 4 and the control unit 13. In FIG. 6, reference numeral 15 denotes a battery arranged in the main body case 1 on the inner surface side of the battery lid 10, and reference numeral 16 denotes a recording unit arranged in the main body case 1 for measuring blood sugar levels and the like. To record.

  A procedure for measuring a patient's blood glucose level in a hospital, for example, using the biological sample measuring apparatus having the above configuration will be described with reference to FIGS.

  Specifically, first, the measurer (nurse or the like) operates the operation unit 7 to display the sample measurement start screen on the display unit 5 (S1 in FIG. 7).

Next, as shown in FIG. 8, the ID displayed by the barcode on the name tag 17 of the measurer (nurse).
The data 18 is read by the data reading unit 3 (S2 in FIG. 7). The ID data 18 is recorded in the recording unit 16.

  Next, as shown in FIG. 9, the data reading unit 3 reads the ID data 20 displayed as a barcode on the wristband 19 fitted to the patient's hand (S3 in FIG. 7). The ID data 20 is recorded in the recording unit 16.

  Next, as shown in FIG. 10, the measurer (nurse or the like) uses the ID data 22 displayed in a barcode on the sensor bottle 21 in which a plurality of sensors 8 (see FIG. 13) are stored. 3 (S4 in FIG. 7). The ID data 22 is recorded in the recording unit 16.

  When reading the ID data 18, 20, and 22 shown in FIGS. 8 to 10, as shown in FIGS. 11 and 12, the measurer (nurse or the like) puts the middle finger 23 into the finger contact groove 6. The operation unit 7 is operated in a state where the sensor mounting unit 4 side of the main body case 1 is gripped in the contact state.

  Here, as described above, the center of gravity position 1A of the main body case 1 is closer to the data reading unit 3 than the finger contact groove 6 as shown in FIG. For this reason, during the operations shown in FIGS. 8 to 10, a slight load is applied to the hands of the measurer (nurse or the like). However, in the present embodiment, the operation unit 7 is in a state where the middle finger 23 of the measurer (nurse or the like) is in contact with the finger contact groove 6 and the sensor mounting unit 4 side of the main body case 1 is gripped. Will be operated. Thereby, since the measurer (nurse or the like) can operate in a stable state with respect to the operations shown in FIGS. 8 to 12, the load during the operation can be reduced as compared with the conventional case.

  When the above operation is completed, the measurer (nurse or the like) operates the operation unit 7 to display the ID data 18, 20, and 22 read from the recording unit 16 on the display unit 5. Then, it is confirmed whether or not the operation so far is properly performed (S5 in FIG. 7).

  Next, the measurer (nurse or the like) takes out one sensor 8 (see FIG. 13) from the sensor bottle 21, and attaches it to the sensor mounting portion 4 as shown in FIG. Specifically, the sensor 8 is mounted on the sensor mounting portion 4 so that the electrode portion provided at the end of the sensor 8 is inserted into the sensor mounting portion 4 (S6 in FIG. 7).

  Here, the insertion of the sensor 8 into the sensor mounting portion 4 and the subsequent operation have the first end side (that is, the display portion 5 side) of the main body case 1 as shown in FIG. Done in state. Specifically, for example, as shown in FIG. 13, the measurer (nurse or the like) places the back side of the first end side of the main body case 1 on the palm and puts the middle finger 23 in the finger rest groove 6. Each operation is performed in the state. That is, each operation after mounting the sensor 8 on the sensor mounting portion 4 is performed in a state where the measurer has the end portion (first end) opposite to the reading operation of the ID data 18 and the like described above. The

  Now, for example, FIG. 13 shows a scene where the blood glucose level of a patient is to be measured from blood 26 that has oozed out from the puncture portion 25 of the index finger 24 of the patient. In addition, as a pre-stage of this blood glucose level measurement, a measurer (nurse or the like) performs a puncture operation on the puncture portion 25 of the patient's index finger 24 using a puncture device (not shown), thereby Then, blood 26 is allowed to flow out from puncture portion 25.

  In this state, as shown in FIG. 13, the measurer (nurse or the like) brings the end of the sensor 8 opposite to the electrode portion into contact with the blood 26 (S7 in FIG. 7).

  At this time, in order to accurately measure the blood glucose level, attention should be paid to the operation of the sensor 8 so as to scoop the blood 26 of the puncture portion 25, or the sensor 8 to be pressed against the blood 26 of the puncture portion 25. Do not operate it. That is, it is important that the sensor 8 is brought into contact with the blood 26 in the puncture portion 25 so that the blood 26 is sucked into the sensor 8 by capillary action at the blood introduction portion of the sensor 8.

  In the present embodiment, the configuration as described above is employed so that such a delicate operation of bringing the sensor 8 into contact with the blood 26 of the puncture portion 25 can be easily performed.

  That is, in the present embodiment, the sensor mounting portion 4 is provided on the second end side of the main body case 1, and the main body case 1 is positioned closer to the sensor mounting portion 4 side than the central portion on the back side of the main body case 1. Finger contact grooves 6 formed along the lateral direction are provided. Then, the weight of the main body case 1 from the finger contact groove 6 to the second end side is made lighter than the weight of the finger contact groove 6 to the first end side. In other words, the biological sample measurement device of the present embodiment is configured such that the position of the center of gravity of the main body case 1 is disposed closer to the first end where the display unit 5 is disposed.

  For this reason, the operation of bringing the sensor 8 mounted on the sensor mounting portion 4 into contact with the patient's puncture portion 25 is performed with the light weight of the main body case 1 in the state where the first end side of the heavy main body case 1 is held. This can be done with the second end side approaching the patient's puncture portion 25.

  Therefore, a delicate work for bringing the sensor 8 into contact with the puncture portion 25 of the patient can be performed more easily than before. Such an effect should be highly evaluated in departments (for example, hospitals) that need to measure biological samples appropriately from many patients in a short time.

  When blood 26 is spotted on the end of the sensor 8 by such an operation, measurement is started in the measurement unit 14 in FIG. 6 (S8 in FIG. 7). Then, after 10 seconds, the measurement result is displayed on the display unit 5 (S9 in FIG. 7).

  The measurement result is recorded in the recording unit 16 in a state associated with the ID data 18, 20, and 22 described above.

  Next, the measurer (nurse or the like) operates the sensor discharge lever 9 toward the left side of FIG. 13 (outward of the second end side of the main body case 1) to move the sensor 8 from the sensor mounting portion 4 to the main body. Discard outside the case 1 (S10 in FIG. 7).

  Next, a measurer (nurse or the like) operates the operation unit 7 to display the ID data 18, 20, 22 and measurement data recorded in the recording unit 16 on the display unit 5 (see FIG. 7). S11), the measurement of the blood glucose level is completed (S12 in FIG. 7).

  After that, when the main body case 1 is mounted on the cradle 2 as shown in FIG. 1, the above-described ID data 18, 20, and 22 are transmitted via the communication window 27 provided on the back surface of the main body case 1 shown in FIG. The measurement data is transferred to the cradle 2 (S13 in FIG. 7). Then, the transferred ID data 18, 20, 22 and measurement data are transferred from the cradle 2 to a host computer in the hospital (S14 in FIG. 7).

  As described above, the biological sample measuring apparatus according to the present embodiment uses the finger rest groove 6 that is touched when the measurer holds the apparatus by hand as the reference position, and the heavy objects such as the display unit 5 and the battery 15 are arranged. The weight balance between the one end side and the second end side where the sensor mounting portion 4 on which the sensor 8 is mounted is arranged is optimized.

  That is, it is configured so that it can be stably operated with the first end side having the center of gravity during the operation of attaching blood or the like to the sensor 8 that requires a delicate operation.

  This eliminates the need for the measurer to hold the lighter side and attach blood or the like to the end of the heavier side, so that a device that is easier to use than before can be obtained.
