Description

  The present invention relates to a blood component measuring apparatus for measuring a component such as glucose from blood collected through a blood introduction path in a test piece mounted on a tip mounting portion.

  For diabetics, daily management by measuring changes in blood glucose levels is recommended. The blood glucose level is measured by providing a measuring section such as a test paper impregnated with a reagent that is colored according to the amount of glucose in the blood, supplying blood to the test paper to cause coloration, and determining the degree of coloration. A blood glucose meter that obtains and displays a blood glucose level by optical measurement has been put into practical use (see, for example, Patent Document 1 and Patent Document 2). The test paper is provided on a disposable test piece, and the test piece is mounted on the tip mounting portion of the blood glucose meter. A blood glucose meter using an electrochemical sensor has also been put into practical use.

  When collecting blood of a diabetic patient, first, the skin (for example, finger, palm, etc.) is punctured with a predetermined puncture device, and a small amount of blood is drained after the puncture. Next, the test piece is attached to the blood glucose meter, the spotted portion at the tip of the test piece is brought into contact with the blood ball, and blood is introduced to the test paper by capillary action through a small diameter passage.

  On the other hand, the recent blood glucose meter is measured by medical staff for multiple patients who are admitted to a medical facility, in addition to personal use for diabetic patients themselves to measure blood glucose on a daily basis. There is a request for in-hospital use.

Utility Model Registration No. 3135393 (FIGS. 2 and 8) US Patent No. 7077328

  By the way, many diabetic patients and the like are elderly people, and there are cases where fingers are handicapped due to complications of diabetes. In addition, even if the fingers are not handicapped, there are some patients who cannot handle the blood glucose meter well when their fingertips shake due to psychological factors or the like when they are unaccustomed to the operation. In particular, since a blood ball obtained by puncture is very small, it is not always easy for a diabetic patient to bring this portion into contact with a spotted portion of a test piece. Further, when the work is performed with the hand trembling, even if the spotted part contacts the blood ball, sufficient blood may not be impregnated in the test paper. In such a case, since the blood glucose meter is not correctly measured, the measurement is performed again by performing puncture after replacing the test piece.

  According to an investigation conducted by the inventor of the present application, if both arms are in the free state in the air, the hand becomes unstable and it is difficult to bring the spotted part into contact with the blood ball. It was found that there are many patients who have stable hands.

  However, if the wrist is placed on the table, the degree of freedom of movement of the wrist is suppressed, the direction of the blood glucose meter cannot be set appropriately, and eventually the patient who is difficult to contact the spotted part with the blood ball There were many. That is, as shown in FIG. 16, the blood ball 900 obtained by puncture in one hand (hereinafter referred to as the left hand) is kept facing upward so as not to drop, but the blood glucose meter 901 held by the right hand and the test The piece 902 is directed obliquely upward (see the arrow in FIG. 16), and it is difficult to apply the tip spotted portion 903 to the blood ball 900.

  Even when the spotting operation is performed in the air, as shown in FIG. 17, if the blood ball 900 is set substantially upward, the blood glucose meter 901 is brought closer to the blood ball 900 from above or obliquely from above. The blood drop 900 and the spotted portion 903 of the test piece 902 become blind spots by the blood glucose meter 901 and the right hand, resulting in poor visibility and difficult spotting operation. Since the spotted portion of the test piece is an operation target portion at the time of blood glucose measurement, visibility during operation is required, and visibility is also required for state confirmation when placed on a table.

  Furthermore, even for medical professionals who are familiar with blood glucose meter operations, bringing a spotted part into contact with a minute blood ball is a work that requires attention, especially for a large number of patients. When performing the measurement, it is desirable that each measurement process be performed as simply as possible, and it is desirable to ensure the visibility of the spotted portion.

  Furthermore, it is desirable that unnecessary external force is not applied to the test piece attached to the blood glucose meter when the table is placed.

  In addition, it is desirable that when the table is placed, the spotted portion can be spotted with blood after the spotted part has been brought close to the blood ball in advance.

  The present invention has been made in consideration of such problems, and it is possible to easily and surely contact a spotted portion of a test piece with a blood ball obtained by puncture to suppress measurement errors. An object of the present invention is to provide a blood component measuring device that can be used.

  The blood component measurement device according to the present invention is a blood component measurement device to which a test piece is attached, wherein a tip mounting portion to which the test piece is attached and a blood introduction path in the test piece attached to the tip mounting portion. And a monitor for displaying the results obtained by the measurement unit and the predetermined control unit, with the display surface of the monitor on the upper side and the opposite side on the lower side. The center axis of the test piece is directed obliquely downward toward the tip when the monitor is placed on a horizontal surface with the display surface of the monitor facing upward.

  In this way, when placed on a horizontal surface, the center axis of the test piece is directed obliquely downward toward the tip side, so that the spotted portion of the test piece points in the direction of the blood ball. It becomes easy, the spotting part of a test piece can be contacted easily and reliably with respect to the blood ball obtained by puncture, and a measurement error can be suppressed.

  Further, the blood component measuring device according to the present invention is a blood component measuring device to which a test piece is attached, wherein blood is introduced into a tip attaching portion to which the test piece is attached, and the test piece attached to the tip attaching portion. A measuring unit that measures a component of blood collected through a path, and a monitor that displays a result obtained by the measuring unit and a predetermined control unit, the display surface of the monitor being on the upper side and the opposite side And the center axis of the test piece is directed obliquely downward toward the distal end with reference to an extension line of the display surface of the monitor in a side view.

  In this way, by setting the center axis of the test piece to be directed obliquely downward toward the tip side with reference to the extension line of the display surface of the monitor, the spotted portion of the test piece is in the direction of the blood ball. The spotted portion of the test piece can be easily and reliably brought into contact with the blood ball obtained by puncturing, and measurement errors can be suppressed.

  The angle between the extension line and the central axis may be 10 ° to 40 °. According to such an angle setting, the spotted portion of the test piece points the direction of the blood ball more correctly.

  A main portion provided with the monitor, and a relay portion provided between the main portion and the tip mounting portion, and an upper surface of the relay portion may be set substantially parallel to the central axis. . In such a relay part, a space for providing several mechanisms related to the tip mounting part is ensured in a suitable direction, and by providing the relay part, the central axis of the test piece is directed obliquely downward toward the tip side. Easy to make. In addition, by setting the upper surface of the relay portion substantially parallel to the central axis of the test piece, the orientation of the test piece can be easily grasped visually.

  An ejector lever may be provided on the upper surface of the relay portion to remove the attached test piece by performing an extrusion operation toward the distal end side. As a result, the ejector lever moves along the upper surface, and it becomes easy to operate, and the movement space of the ejector lever can be secured.

  In the top view, the relay part may be continuous and concave from the main part and narrow toward the tip side. As a result, the relay portion becomes moderately thin and has a concave shape, so that it is easy to grip with the fingertip. Moreover, since the relay part is close to the tip mounting part, the mounted test piece can be stabilized by gripping the relay part.

  The main part may have a substantially constant thickness in the vertical direction, and the main part and the relay part may be connected by a continuous curved surface having a concave bottom surface in a side view. It is easy to put a finger on such a concave and continuous curved surface, and it is easy to grasp the blood component measuring device.

  When the test piece is mounted on the tip mounting portion and placed on a horizontal plane with the display surface of the monitor facing upward, the distance between the tip spotted portion of the test piece and the horizontal plane is 3 mm to 30 mm. Also good. As a result, while placing the finger or palm on which the blood ball is formed on the table, the blood glucose meter can be moved close to the blood ball while being placed on the table, so that blood spotting can be performed. Blood glucose measurement can be easily performed even for a handicapped patient. Moreover, when placing on the table, the visibility of the spotted part is good, and the state can be confirmed.

  When the monitor is placed on a horizontal plane with the display surface facing upward, the distance between the highest point on the lower surface and the horizontal plane may be 3 mm to 20 mm. As a result, an appropriate gap is ensured for putting a finger when it is placed on the table, making it easier to grip.

  When the test piece is mounted on the tip mounting portion and placed on a horizontal plane with the display surface of the monitor facing upward, the test piece may be separated from the horizontal plane. Thereby, unnecessary external force is not applied to the test piece.

  The blood component measuring apparatus according to the present invention has a shape in which the center axis of the test piece is directed obliquely downward toward the distal end when placed on a horizontal surface (in other words, an extension line of the display surface of the monitor). As a reference, the center axis is oriented obliquely downward toward the tip side), so that the spotted portion of the test piece can easily point in the direction of the blood ball, and the blood ball obtained by puncture On the other hand, the spotted portion of the test piece can be contacted easily and reliably, and measurement errors can be suppressed.

  Hereinafter, embodiments of the blood component measuring apparatus according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 1, 2, and 3, the blood glucose meter (blood component measuring device) 10a according to the present embodiment has a test piece 12 attached to the tip. First, the test piece 12 will be described.

  As shown in FIG. 4, the test piece 12 includes a base tube 14, a flange 16 that covers one of the base tubes 14, a conical protrusion 18 that protrudes from the flange 16, and a test paper that is attached to the back surface of the flange 16. And 20. The base tube 14 is provided with a plurality of slits 14a (see FIG. 1). In the center of the protrusion 18, a straight blood introduction path 24 that communicates from the spotted portion 22 at the tip to the test paper 20 is provided. Examples of the material of the test paper 20 include polyethersulfone. Examples of the reagent impregnated in the test paper 20 include color formers such as glucose oxidase (GOD), peroxidase (POD), 4-aminoantipyrine, and N-ethyl N- (2-hydroxy-3-sulfopropyl). It is done. The reagent may contain a predetermined buffer. The blood introduction path 24 is generally provided on the central axis C of the test piece 12. The center axis C of the test piece 12 is a direction in which the spotting portion 22 of the test piece 12 faces and is a straight line passing through the tip of the spotting portion 22.

  The test piece 12 is a so-called disposable product, and is packaged in an individual package (not shown) and sterilized in advance. The blood introduction path 24 is set to have a sufficiently small diameter so that blood is sucked up by capillary action, and introduces the blood in contact with the spotting portion 22 to the test paper 20. As the test piece 12, a conventional product can be applied as it is.

  Returning to FIG. 1 to FIG. 3, the blood glucose meter 10 a according to the present embodiment includes a tip mounting portion 30 to which the test piece 12 is mounted and a blood introduction path 24 in the test piece 12 mounted to the tip mounting portion 30. A measuring unit 32 for measuring the coloration of the test paper 20 by the blood components collected in this manner, a liquid crystal monitor 34 for displaying the result measured by the measuring unit 32 via a control unit (microcomputer or the like) 33, It has an ejector lever 36 for removing the test piece 12 mounted by pushing out toward the distal end side, an operation button group 38, an auxiliary function button 40, and a cap 39 for protecting the distal end mounting portion 30. The blood glucose meter 10a has a smooth shape with no corners as a whole. Since it becomes complicated, the cap 39 is omitted except for FIG. The measurement unit 32 can employ various mechanisms according to the component detection method of the test piece 12.

  The blood glucose meter 10a is used in a hospital where a medical staff measures a plurality of patients admitted to a medical facility, and is provided with a data recording / calling function for each patient and a button therefor. It is slightly larger than the personal use blood glucose meter 10c (see FIG. 13). Of course, the blood glucose meter 10a can be used for personal use without any special modification.

  The tip mounting portion 30 has a cylindrical shape since the test piece 12 is mounted, and the test piece 12 can be easily and stably mounted by inserting the base tube 14 (see FIG. 4).

  The blood glucose meter 10a is controlled by an internal control unit 33, and continuously projects and receives light on the test paper 20 by the measurement unit 32 constituted by optical means, and a predetermined color based on the coloration is obtained. The blood sugar level is obtained by calculation and displayed on the monitor 34. When the color reaction of the test paper 20 is not observed or insufficient, a predetermined error display is performed. The control procedure of blood glucose level measurement by the blood glucose meter 10a is basically the same as that of the blood glucose meter according to the prior art.

  The monitor 34 includes a blood glucose level display unit 34a that displays a blood glucose level, and an auxiliary display unit 34b that displays time and other information. The blood glucose level display unit 34a can display a three-digit number and a predetermined character display (for example, “OK”). Since some diabetics have weak visual acuity, the monitor 34 is set sufficiently large in consideration of visibility. The monitor 34 is at least a liquid crystal display surface.

  The operation button group 38 is collectively provided on the base end side, and includes a power button 38a, movement buttons 38b and 38c, selection buttons 38d and 38e, and an LED display unit 38f. The movement buttons 38b and 38c have functions such as moving an item displayed on the monitor 34 or scrolling the screen along with the movement. The selection buttons 38d and 38e have functions such as selecting a function displayed on the monitor 34 corresponding to each position. The LED display unit 38f has a function of notifying the state of the blood glucose meter by turning on and blinking in various colors by the LED.

  The ejector lever 36 is provided on the upper surface 46a in the vicinity of the distal end mounting portion 30 and is a round lever having a size suitable for placing a finger. The ejector lever 36 has a flat portion 36a on the proximal end side and a protruding portion 36b on the distal end side. And have. The ejector lever 36 is movable along the upper surface 46a. The flat portion 36a is provided with a plurality of horizontal stripes to prevent slipping. The protrusion 36b has a width and a height suitable for applying a fingertip. The ejector lever 36 is elastically biased toward the base end side by a moderately weak elastic body. When the finger is pushed and pushed out to the front end side, the ejector lever 36 moves parallel to the axial direction of the cylindrical tip mounting portion 30. The test piece 12 can be pushed out in conjunction with the internal ejector mechanism and removed from the tip mounting portion 30. Moreover, according to such a structure, the dirt can be easily wiped off.

  The auxiliary function button 40 is a button used for a function specific to hospital use.

  Next, the shape of the blood glucose meter 10a will be described. For convenience of explanation, the display surface of the monitor 34 is on the upper side, and the opposite side is on the lower side. However, the direction of the blood glucose meter 10a at the time of use and storage is not limited to this.

  The housing of the blood glucose meter 10a is mainly configured by combining an upper housing 42a provided with a monitor 34 and an operation button group 38 and a lower housing 42b constituting a lower portion. When the blood glucose meter 10a is placed on the table T, a small protrusion 43 is provided in a portion of the lower housing 42b that contacts the table T.

  The blood glucose meter 10a is divided into a main part 44 provided with the monitor 34 and the operation button group 38 and a relay part 46 provided between the main part 44 and the tip mounting part 30 in a top view (see FIG. 2). can do. The relay portion 46 is configured to be continuous and concave from the main portion 44 and narrow toward the distal end side, and the distal end mounting portion 30 is provided on the distal end surface.

  The main part 44 is provided with a monitor 34 and has a certain width, but is wide enough to be gripped by human hands. The main portion 44 has a substantially constant width in the length direction (the direction of arrow A in FIGS. 2 and 3) when viewed from the top (see FIG. 2) and substantially constant in the vertical direction when viewed from the side (see FIG. 3). It is easy to grip. Further, the blood glucose meter 10a has a bilaterally symmetric shape and can be easily grasped by either the right hand or the left hand.

  In addition to the main part 44, the blood glucose meter 10a can also hold the relay part 46. As shown in FIG. 5, the relay part 46 is continuous and concave from the main part 44 and narrows toward the distal end side, and is moderately thin and concave. . Further, since the relay part 46 is close to the tip mounting part 30, the mounted test piece 12 can be stabilized by gripping the relay part 46.

  The relay unit 46 has a space in which several mechanisms related to the tip mounting unit 30 (for example, a measurement unit 32 for the test paper 20, an ejection mechanism of the test piece 12, a mechanism for holding the tip mounting unit 30, etc.) are suitable. In addition, by providing the relay portion 46, the central axis C of the test piece 12 can easily be directed obliquely downward toward the tip side. Moreover, the upper surface 46a of the relay part 46 is set substantially parallel to the central axis C of the test piece 12, and it is easy to visually grasp the orientation of the test piece 12.

  Further, an ejector lever 36 is provided on the upper surface 46a of the relay portion 46, and the ejector lever 36 operates along the upper surface 46a, which makes it easy to operate, and provides a space for moving the ejector lever 36. It can be secured.

  In a side view (see FIG. 3), the display surface of the monitor 34 is the upper side, the opposite side is the lower side, and the center axis C is obliquely downward toward the tip side with reference to the extension line L of the display surface of the monitor 34. Oriented. In other words, when the monitor 34 is placed on a horizontal table T (horizontal plane) with the display surface facing upward, the central axis C of the test piece 12 is directed obliquely downward toward the distal end side. At this time, the angle θ1 formed by the extension line L and the central axis C is 27 °, and the angle θ2 formed by the extension line L and the table T is 7 °. Further, the test piece 12 mounted on the tip mounting portion 30 is separated from the table T, and no unnecessary external force is applied to the test piece 12.

  The lower surface of the main portion 44 and the lower surface of the relay portion 46 are connected by a continuous curved surface 50 that is concave in a side view. A finger hooking projection 52 is provided in the vicinity of the base end side when viewed from the curved surface 50. The finger hooking protrusion 52 has a low triangular shape in a side view, forms a smooth substantially circular arc together with the curved surface 50, and has a space enough for one finger to enter. It is easy to put a finger on such a curved surface 50 and to easily hold the blood glucose meter 10a.

  The distance H1 between the spotting part 22 and the table T in the blood glucose meter 10a is 13 mm, and the distance H2 between the highest point P on the lower surface and the table T is 11 mm. The highest point P is a part of the curved surface 50.

  Since the spotting part 22 is a part to be operated at the time of blood glucose measurement, visibility at the time of operation is required, and visibility is also required for status confirmation when it is placed on the table T. Although it is preferable to keep the spotting part 22 away from the table T, it is not rational to make it leave wastefully. Furthermore, as will be described later (see FIGS. 8 and 9), there is a preferable range of the distance H1 in consideration of the spotting operation with the blood glucose meter 10a placed on the table T. From such a viewpoint, the distance H1 may be set in the range of 3 mm to 30 mm, preferably in the range of 9 mm to 14 mm.

  When grasping the blood glucose meter 10a placed on the table T, it is desirable that there is an appropriate gap between the highest point P and the table T for inserting a finger, and the distance H2 is in the range of 3 mm to 20 mm. Preferably, it may be set in the range of 7 mm to 12 mm.

  Next, the usage method of the blood glucose meter 10a comprised in this way is demonstrated.

  First, the blood glucose meter 10a is turned on, the cap 39 is removed, the test piece 12 is pushed together with the case of the individual package into the tip mounting portion 30 until a click is felt, and then only the case is removed. As a result, the test piece 12 is mounted on the tip mounting portion 30. After the test paper 20 is detected, the measurement unit 32 displays “OK” on the monitor 34 and automatically shifts to the blood glucose measurement mode. Further, puncture is performed with a predetermined puncture device, and a blood ball 60 is provided on the fingertip (hereinafter, referred to as the left index finger).

  As shown in FIG. 6, the patient performs a spotting operation in which the spotting portion 22 of the test piece 12 is brought into contact with the blood ball 60 in a state where the blood glucose meter 10 a is held with the right hand. At this time, the left and right wrists or the vicinity thereof are placed on the table T and stabilized.

  As is apparent from FIG. 6, when the left and right wrists are normally placed on the table T, the back of each hand is obliquely outward, the left index finger is inward, and the blood glucose meter 10a is held by the palm of the right hand. The portion 44 is oriented obliquely inward. Then, since the relay portion 46 is bent by θ1 (= 27 °) with respect to the main portion 44, the protrusion 18 and the central axis C of the test piece 12 are inward and substantially horizontal, and the blood ball 60 is directed. To do. At this time, the blood ball 60 on the left hand side and the spotting part 22 on the right hand side are approaching inward, and there is nothing to block from the patient's line of sight, so that the visibility is good.

  Next, as shown in FIG. 7, a spotting operation is performed with the right hand and the left hand approaching substantially horizontally with both wrists placed on the table T.

  The operation at this time is simple, for example, by simply twisting both wrists inward, and can be performed stably with the wrists placed on the table T. Therefore, even if the fingers are inconvenient or unfamiliar with the operation of the blood glucose meter 10a, the small blood ball 60 and the spotting portion 22 are correctly brought into contact with each other without shaking the fingertips, and reliable spotting is achieved. Action is taken. Since the protrusion 18 and the central axis C are in contact with the blood ball 60 oriented, the blood ball 60 is prevented from adhering to the periphery of the spotting portion 22, the side surface of the protrusion 18, or the flange 16. it can.

  As shown in FIG. 8, in order to perform a more reliable spotting operation, the blood glucose meter 10a is placed on the table T, while one finger 68 (for example, index finger) on which the blood ball 60 is formed is placed on the table T. Alternatively, the blood glucose meter 10a may be brought close to the head while being placed on the head.

  As described above, the distance H1 from the table T of the spotting portion 22 is 13 mm. On the other hand, when one finger 68 is placed on the table T, the height of the blood ball 60 is generally in the range of 3 mm to 20 mm, usually about 5 mm to 14 mm, and even if it is not initially 13 mm, the orientation of the finger 68 and Since the height can be adjusted in such a range, it is easy to match the height to the spotting portion 22, and the spotting portion 22 is easily spotted on the blood ball 60. At this time, since the finger 68 and the blood glucose meter 10a are directly placed on the table T, they are extremely stable, and a reliable spotting operation is performed.

  Further, as shown in FIG. 9, one finger 69 (for example, the middle finger) adjacent to the finger 68 on which the blood ball 60 is formed may be placed on the table T, and the finger 68 may be placed thereon. When the two fingers 68 and 69 are placed on the table T, the height of the blood ball 60 on the upper finger 68 varies depending on how the fingers are assembled, how the fingers are placed, etc., and is generally in the range of 5 mm to 30 mm, usually 9 mm to Since the orientation and height of the finger 68 can be adjusted in such a range even if it is about 20 mm and not initially 13 mm, it is easy to match the height with respect to the spotting portion 22, The spotting part 22 can be easily spotted on the blood ball 60. At this time, since the blood glucose meter 10a is directly placed on the table T, it is extremely stable. The finger 68 is placed on the finger 69, is reasonably stable, and a reliable spotting operation is performed.

  That is, when only one finger 68 is placed on the table T (see FIG. 8), the stability is improved, and when two fingers 68 and 69 are placed on the table T (see FIG. 9), the spot 22 Since the height can be easily adjusted, any one of the spotting operations may be performed according to the patient's familiarity.

  However, when three or more fingers (for example, the index finger, middle finger, and ring finger) are placed on the table T, the top finger (index finger) becomes unstable even if it is a healthy person, and the fingers are inconvenient. The patient may become quite unstable, and it may be difficult to perform the spotting operation. Therefore, the distance H1 from the table T to the spotting portion 22 is preferably set in a range of 3 mm to 30 mm, preferably in a range of 9 mm to 14 mm, which is a height corresponding to one finger or two fingers. It is.

  Of course, as a method of using the blood glucose meter 10a, the spotting operation may be performed in the air without using the table T when there is no concern about shaking the hand.

  Next, when a correct spotting operation is performed, the blood ball 60 is sucked into the blood introduction path 24 by capillary action, and a sufficient amount of the test paper 20 is impregnated, and a color reaction is exhibited according to the blood sugar level by the reagent. The measurement unit 32 observes the color reaction of the test paper 20, and when the color reaction is stable, the control unit 33 obtains a blood sugar level by a predetermined calculation based on the color reaction and displays it on the monitor 34. At the same time, the buzzer notifies the end of the measurement. During the observation of the color reaction and the calculation of the blood glucose level, the scheduled time until the end of the measurement may be displayed on the monitor 34 to indicate the progress of the measurement.

  Thereafter, as post-processing, the test piece 12 is covered with a cover of the individual package, the ejector lever 36 is operated, the test piece 12 is removed together with the cover, the power is turned off, and the tip mounting portion Put cap 39 on 30.

  The operation method shown in FIGS. 6 to 9 is a case of personal use in which the patient himself / herself performs blood glucose measurement. However, as shown in FIG. 10, even when the medical worker 62 operates the blood glucose meter 10a for in-hospital use. Good. As is clear from FIG. 10, when the medical worker 62 performs a spotting operation on the patient 64 sleeping on the bed 63, the relay unit 46 is bent downward with respect to the main unit 44. Even when the portion 46 is angled to some extent, the main portion 44 is substantially horizontal, and the medical worker 62 can hold the blood glucose meter 10a in an easy posture with the elbows lowered, and the palm 66 has the blood balls 60 and dots. The wearing part 22 does not become a blind spot and is excellent in visibility. Therefore, in the blood glucose meter 10a, even in such in-hospital use, the spotted portion 22 can be easily and reliably brought into contact with the blood ball 60, and measurement errors can be suppressed.

  As described above, according to the blood glucose meter 10a according to the present embodiment, when placed on the horizontal table T, the center axis C of the test piece 12 is directed obliquely downward toward the distal end side. (In other words, with the extension line L of the display surface of the monitor 34 as a reference, the center axis C is directed obliquely downward toward the tip side), so that the spotted portion of the test piece is a blood ball. This makes it easier to direct the direction of the point, and the spotted portion 22 of the test piece 12 can be easily and reliably brought into contact with the blood ball 60 obtained by puncturing, thereby suppressing measurement errors.

  The angle θ1 formed by the extension line L and the central axis C may be 10 ° or more, preferably 15 ° or more in order for the spotting portion 22 to point the direction of the blood ball 60 more correctly. On the other hand, when the angle θ1 is increased, the relay unit 46 is excessively downward, so that the visibility of the spotting unit 22 is deteriorated when the blood glucose meter 10a is gripped and placed, or the sense of stability is impaired. There is a concern that the wearing part 22 may not be oriented in the direction of the blood ball 60 or the test piece 12 may come into contact with the table T during placement. Therefore, the angle θ1 may be 40 ° or less, preferably 30 ° or less. After all, the angle θ1 is set in the range of 10 ° to 40 °, preferably in the range of 15 ° to 30 °, taking into consideration the influence on the dimensions of each part.

  Next, blood glucose meters 10b, 10c, and 10d according to modifications will be described. Regarding the blood glucose meters 10b to 10d, the same portions as those of the blood glucose meter 10a are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 11, the blood glucose meter 10 b according to the first modification is obtained by changing the tip mounting portion 30 of the blood glucose meter 10 a to a tip mounting portion 72 so that the test piece 70 can be mounted. As shown in FIG. 12, the test piece 70 has a thin and thin plate shape, and a blood introduction path 74 is provided on the central axis C. As the test piece 70, a conventional product can be applied as it is.

  Unlike the blood glucose meter 10a, the blood glucose meter 10b measures the blood glucose level based on the current value obtained by the electrochemical sensor instead of the optical means in the measurement unit 32.

  In the blood glucose meter 10b, like the blood glucose meter 10a, the central axis C of the test piece 70 is directed obliquely downward toward the distal end, and the angle θ1 formed by the extension line L and the central axis C is 27 °. Is set to

  As shown in FIGS. 13 and 14, the blood glucose meter 10c according to the second modification is for personal use, and has fewer buttons in the operation button group 38 than the blood glucose meter 10a. There is no function button 40 and it is small. The monitor 76 that displays the blood glucose level is smaller than the monitor 34.

  Since the blood glucose meter 10c is smaller than the blood glucose meter 10a, the angle θ1 formed by the extension line L and the central axis C is 18 °, the angle θ2 is 5 °, H1 is 10 mm, and H2 is related to the dimensions of each part. It is set to 7 mm.

  As shown in FIG. 15, the blood glucose meter 10 d according to the third modification has a small and thin shape suitable for carrying, has no portion corresponding to the relay unit 46, and has a tip mounting portion 30 on the tip end surface 78. Is provided. The tip end surface 78 has a shape inclined obliquely in a side view (a side view is omitted), and the center axis C of the test piece 12 is directed toward the tip with reference to the extension line L of the display surface of the monitor 80. It is directed diagonally downward.

  In the blood glucose meters 10b to 10d according to the first to third modifications, the central axis C of the test piece 12 (or the test piece 70) is based on the extension line L as in the blood glucose meter 10a. It is directed diagonally downward toward the tip side. Therefore, in any case of hospital use or personal use, the spotting portion 22 of the test piece 12 (or the test piece 70) can be easily oriented in the direction of the blood ball 60, and the blood ball 60 obtained by the puncture can be directed. The spotting part 22 can be contacted easily and reliably, and measurement errors can be suppressed.

  The blood glucose meters 10a to 10d measure the blood glucose level as a characteristic of the sample, but are not limited to this, and can also be applied as a device (blood component measuring device) that measures hormone concentration, cholesterol concentration, and the like.

  The blood component measuring apparatus according to the present invention is not limited to the above-described embodiment, but can of course adopt various configurations without departing from the gist of the present invention.
