Description

  The present invention relates to a disposable sheet structure for sticking to an optical biological measurement sheet such as a blood oxygen saturation measurement sheet.

  Conventionally, for example, as a device for measuring blood oxygen saturation in arteries, two types of light are emitted from a light emitting unit to the artery through the skin, and the light is received by a light receiving unit disposed on the skin surface opposite to the light emitting unit. In addition, there is a so-called optical biological measurement sensor that measures oxygen saturation in blood by a change in light during that time (see, for example, Patent Document 1).

  Such a sensor is used, for example, to determine how much blood is supplied from the heart by mounting the device on a fingertip or earlobe when suffering from myocardial infarction.

  As a specific structure, a rectangular resin film release sheet is detachably attached to the lower surface of the center narrow sensor sheet, and a constant width is fixed to the lower surface of the center narrow sensor portion of the sensor sheet. The light emitting part and the light receiving part are disposed with the element action surface as the lower surface while maintaining a gap. The light emitting unit is provided with a red LED and an infrared LED adjacent to each other, and the light receiving unit is provided with a light receiving sensor for receiving light from these light emitting units.

  The light emitting element and the light receiving element in the light emitting part and the light receiving part are fixed to the upper surface of the sensor sheet with a strip-shaped fixing tape with the element action surface as the lower surface.

  The light emitting unit and the light receiving unit are electrically connected to the biological information monitor via a cable.

  In actual use, first, a portion having a flat and constant thickness, for example, a portion to be measured such as a fingertip or an earlobe, is selected as the optical biometric sensor mounting portion.

  Next, a narrow-center sensor sheet from which the sensor release sheet has been peeled off is attached to this portion, for example, the fingertip of the index finger, by bending from the narrow center portion.

  In this state, the light emitting part and the light receiving part are located on the finger back and finger pad surfaces of the fingertip, respectively, and especially when the central narrow part of the substantially gourd type is bent, no folding folds are generated. The part and the light receiving part are in close contact with the fingertip in a state of being opposed to each other with the fingertip part interposed therebetween.

  When the light emitting unit and the light receiving unit are energized in this way, the two types of light emitted from the light emitting unit pass through the tip tissue of the index finger, optically react with hemoglobin in the artery, and analyze the wavelength received by the light receiving unit. By doing this, blood oxygen saturation can be measured.

JP 2000-237170 A

An optical biological measurement sensor is configured and used as described above, but a sensor sheet having a light emitting / receiving unit is used to adhere to a measured part of a specimen, usually a specimen skin surface. After use, it will be discarded and, as a rule, will not be reused for different specimens.
However, since the optical biometric sensor is expensive, it is economically disadvantageous to dispose of it for each measurement. Therefore, a used sheet is used between the optical biometric sensor and the specimen. Intervening technology is considered. Then, by discarding only this disposable sheet after the measurement, the optical biometric sensor can be used many times because it does not directly contact the specimen skin surface, which is economically advantageous.
However, it is extremely difficult to mount the sensor sheet, which constitutes an optical biometric sensor with a disposable sheet interposed therebetween, to the measurement site accurately and with good adhesion. This is because the quality factor of sticking to the measurement site is primarily a disposable sheet that is not visible from the outside, so that the positions of the light emitting part and the light receiving part are closely attached to the measurement site position through the disposable sheet. This is because it is difficult to accurately face each other.
As one of the reasons, when using a blood oxygen saturation measurement sensor having a measurement site as a fingertip, the sensor sheet provided with a light emitting / receiving portion at the fingertip portion must be folded in two.

  However, since the disposable sheet is pasted on the lower surface of the sensor sheet in advance, the folding position or the folding in the case of folding the disposable sheet that is not visible from the outside so that the light emitting and receiving part is accurately opposed at the fingertip However, there has been a problem that the work for ensuring the adhesion of the disposable sheet is extremely difficult.

It is configured in a shape having a narrow portion, and further, on one surface of the release sheet, each marker is abbreviated to correspond to the light emitting portion position marker and the light receiving portion position marker displayed on the surface of the sensor sheet. By displaying the sticking light emitting part marker and sticking light receiving part marker to match, there is a great economic advantage because the optical biometric sheet can be used many times just by replacing the disposable sheet, When the disposable sheet that is integrally bonded to the optical biometric sheet is directly bonded to the test specimen, the sticking light emitting / receiving part marker that is substantially the same as the sensor sheet is displayed at the corresponding position. While visually recognizing the light emitting / receiving position marker and the center folding curve displayed on the sheet from the front side, the disposable sheet can be adhered to the measured portion accurately and closely.
Therefore, there is an effect that the light emitting / receiving portion having the action surface facing downward can be accurately positioned on the measurement target portion while being visually recognized from the back side and can be directly attached to the measurement target portion via the disposable sheet.

Since the sticking fold line and the center fold curve coincide with each other, it is possible to accurately determine the position to be folded in the disposable sheet, and it is possible to measure the exact facing position of the light emitting and receiving part It has the effect.

  According to the invention of claim 4, the sensor cord base connected to the light receiving and emitting part of the sensor sheet when the disposable sheet is integrally attached to the sensor sheet is located at one end of the release sheet. Since the code marker is displayed, the code marker is also displayed on the release sheet, so that the appropriate position for attaching the optical biometric sheet can be more accurately disposed on the measurement target portion via the release sheet. Thus, there is an effect that accurate biological data can be obtained by the optical biological measurement sheet.

  Further, according to the invention of claim 5, the light emitting / receiving portion position marker and the bi-fold position marker displayed on the front side of the sensor sheet are formed on the surface of the belt-like fixing sheet for fixing and protecting the light emitting / receiving portion to the sensor sheet. Since the display of each marker is easy to see and the display can be easily created, there is an effect that the disposable sheet can be attached more accurately.

  An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view showing an optical biometric sheet and a disposable sheet connected to a biological monitor, FIG. 2 is a plan view showing the optical biometric sheet, and FIG. FIG. 4 is a cross-sectional view taken along the line II of the optical biological measurement sheet shown in FIG. 2, and FIG. 5 is an XX cross-sectional view of the optical biological measurement sheet shown in FIG.

Before explaining the sticking disposable sheet S used for the optical biometric sheet A of the present invention, the optical biometric sheet will be described in detail.
The optical biometric sheet for integrally attaching the sticking disposable sheet S of the present invention will be described while exemplifying the blood oxygen saturation measuring sheet A as a sensor sheet.

  As shown in FIGS. 1, 2, 4, and 5, the blood oxygen saturation sheet A is a substantially rectangular sensor sheet 11 having a narrow central portion 10 formed by recessing both side edges of the central portion. And a sensor release sheet 12 adhered to the lower (back side) surface of the sheet 11, and a rectangular central longitudinal direction to fix the light receiving unit 13 and the light emitting unit 14 to the upper (front side) surface of the sheet 11. The fixed tape 15, and the light emitting unit 14 and the light receiving unit 13 disposed so as to be positioned at the left and right outer positions of the central narrow portion 10 between the sensor sheet 11 and the fixed tape 15.

  The sensor sheet 11 is made of a substantially transparent material, such as a resin film, and a sensor release sheet 12 made of a resin film is detachably attached to the back surface thereof.

  The light emitting unit 13 and the light receiving unit 14 are respectively composed of a light emitting element 13a and a light receiving element 14a. The light emitting element 13a is composed of two types of light emitting elements, that is, two types of red light LEDs (light emitting elements) approximating blood color and red. It is composed of external light LEDs (light emitting elements) and emits light having different wavelengths. That is, red light having a wavelength of 660 nm emitted from the red light LED passes through or is absorbed by oxygenated hemoglobin and reduced hemoglobin in the blood, and is received by the light receiving element and calculated as a red signal amount, while the infrared light LED emits light. Infrared light having a wavelength of 800 nm to 940 nm passes through or is absorbed by oxygenated hemoglobin and reduced hemoglobin in blood, is received by a light receiving element and is calculated as an infrared signal amount, and blood is calculated from the ratio of these red signal amount and infrared signal amount. It is possible to measure the arterial oxygen saturation (SpO2: Percutaneous Oxygen Saturation).

  In addition, the light emitting / receiving portions 14 and 13 are disposed on the surface of the sensor sheet 11 at positions spaced apart from each other at the left and right outer positions of the central narrow portion 10, and the working surfaces of the light receiving and emitting portions 14 and 13 are also provided. Is on the surface side of the sensor sheet 11, that is, downward. Then, when the sensor sheet 11 is folded in two on the fingertip portion and mounted, the light emitting portion 13 and the light receiving portion 14 are disposed and configured so as to face each other with the fingertip portion interposed therebetween. .

  The light emitting / receiving elements 14 a and 13 a are fixed from the outer surface of the sensor sheet 11 via a belt-like fixing tape 15.

  The fixing tape 15 is composed of an upper fixing tape 15a and a lower fixing tape 15b, and adheres the back surface of the upper fixing tape 15a and the surface of the lower fixing tape 15b, and further folds the fixing tape 15b in the width direction. The light emitting / receiving portions 14 and 13 are sandwiched between the upper and lower lower fixing tapes 15b and 15b. The front and back surfaces of the lower fixing tape 15b are configured to be capable of being adhered. In the figure, 15c is an opening formed in the lower fixing tape to transmit light from the light emitting / receiving sections 14 and 13, and 15b 'is an adhesive layer formed on the front and back surfaces of the lower fixing tape, respectively. The adhesive layer is made of a material that can transmit light transmitted from the light emitting and receiving units 14 and 13.

  What is important is that the sensor sheet 11 is made of a substantially transparent material, for example, a transparent resin film, and is configured such that light having a predetermined wavelength is transmitted from the light emitting / receiving portions 14 and 13 on the upper surface (front surface) side. .

  A sensor cord C for conducting to the biological monitor M is connected to the light emitting / receiving units 14 and 13.

  In the blood oxygen saturation sheet A configured as described above, in the normal conventional method, when the sensor release sheet 12 attached to the lower surface of the sensor sheet 11 is peeled off, the lower surface of the sensor sheet 11 is measured. Since the adhesive 11a which can be stuck on the part is applied, the sensor sheet 11 is stuck on the part to be measured through the adhesive 11a.

  At this time, for example, when the measurement site is the tip of the index finger F, as shown in FIG. 9, the center narrow portion 10 is folded in half around the center narrow portion 10 so that the center narrow portion 10 is the tip F1 of the index finger F. The sensor sheet 11 is attached so that the two halves of the sensor sheet 11 are positioned on the finger pad F2 and the finger back F3 of the tip F1 of the index finger F, respectively.

  The normal blood oxygen saturation sheet A is affixed to the tip of the index finger F in a folded manner as described above, and light emitted from the light emitting unit 14 having a predetermined wavelength is transmitted through the blood of the index finger F and the light receiving unit. The light is received at 13, and the received light data is analyzed to measure blood oxygen saturation.

  When these conventional blood oxygen saturation sheets are attached to the index finger, they must be disposed of and discarded to avoid so-called reuse.

  Therefore, by using the disposable sheet S of the present invention shown in FIG. 1, FIG. 3, and FIG. 6, the same blood oxygen saturation sheet A can be reused many times in the portion to be measured.

Disposable sheet S, the sheet A for the backside optical biometric and freely affixed to the front surface, the back surface is constructed by bonding the exfoliation sheet 22 releasably. An adhesive is applied to the back surface of the disposable sheet S so that it can be attached to a measurement site, and a release sheet 22 is attached to the surface of the disposable sheet S so as to be peelable.

Moreover, the outer shape of the disposable sheet S is formed into a shape having a central narrow portion 20 that substantially matches the outer shape of the sensor sheet 11 of the blood oxygen saturation sheet A, which is a transparent material. When the disposable sheet S and the sensor sheet 11 are overlapped with the same outer shape, the adhesive release sheet 22 is attached so as to correspond to the light emitting part position marker 16 and the light receiving part position marker 17 displayed on the upper surface of the sensor sheet 11. On the back side, substantially the same sticking light emitting part marker 26 and sticking light receiving part marker 27 are displayed.
In addition, the code | symbol 16a in a figure is the light emission part position marker line displayed on the surface of the sheet | seat 11 for sensors in order to perform the horizontal alignment of the light emission part position marker 16 of the sheet | seat 11 for sensors, 17a is a light-receiving part. This is a light receiving portion position marker line displayed on the surface of the sensor sheet 11 in order to align the position marker 17 in the longitudinal direction.
26a is a sticking light emitting part marker line displayed on the back surface of the sticking release sheet 22 in order to align the sticking light emitting part marker 26 in the longitudinal direction, and 27a is a longitudinal alignment of the sticking light receiving part marker 27. It is the sticking light-receiving part marker line displayed on the back side of the sticking release sheet 22 for performing.

  Furthermore, on the back surface of the release sheet 22, a sticking fold line 22 a is displayed at the center. This sticking fold line 22 a corresponds to a position corresponding to the central folding line 11 b displayed on the surface of the sensor sheet 11 when the disposable sheet S is stacked on the sensor sheet 11, that is, a fold corresponding to a two-fold portion of the disposable sheet S. It is displayed in the line part. The disposable sheet S is made of a transparent material. When the disposable sheet S is pasted on the upper surface of the release sheet 22, the sticking folding line 22 a printed on the back surface of the release sheet 22, the sticking light emitting part marker 26, sticking. The light receiving portion marker 27 can be visually recognized from the outside through the transparent disposable sheet S from the surface of the release sheet 22.

  In addition, on each marker 26, 27, etc. on the back surface of the release sheet 22, a disposable sheet is printed from the front side of the disposable sheet S that is integrally attached to the sticking release sheet 22 by printing the use instructions of true reverse characters. The usage instructions for S can be easily read. In addition, the disposable sheet S integrally attached to the sticking release sheet 22 naturally uses a translucent or transparent polyethylene resin sheet, polyurethane resin sheet, or the like, so that the sticking fold line 22a on the back of the sticking release sheet 22 is obtained. Each marker 26, 27, each marker line 26a, 27a, etc. is configured to be easily transmitted and visible from the outside.

  Further, when the sensor sheet 11 is stacked on the surface of the disposable sheet S, the sheet is accurately stacked if the corresponding markers and marker lines of the respective sheets are aligned with reference to the central narrow portion 10 of each sheet. Although this is mainly possible in the right-and-left direction, it is only possible to overlap each sheet and the sensor sheet 11 with each other.

  However, since it is a sheet of translucent material, it is difficult to match the outline accurately. Therefore, a horizontal line L for matching the vertical edge line 11 ′ of the sensor sheet 11 is displayed in advance on the upper and lower edge portions of the back surface of the disposable sheet S, and the sensor sheet 11 is vertically moved along the horizontal line L. By aligning the edge line 11 ', the vertical alignment of the sheets S and 11 can be performed easily and accurately.

  Note that the horizontal line L may be a simple horizontal line, or as shown in FIG. 6, a black belt is used so that it is easy to see visually when the upper and lower edge lines 11 'of the translucent sensor sheet 11 are aligned. It is good. Moreover, the horizontal line L of the black belt of the sticking release sheet 22 is continuous with the right edge. The portion corresponding to the central narrow portion 10 of the sensor sheet 11 is cut out of the horizontal lines L of the left and right and upper and lower black belts so that the left and right upper and lower edge lines 11 ′ of the central narrow portion 10 can be easily matched. ing. In the figure, L1 is an arrow marker displayed for recognizing the code marker 25.

[how to use]
The disposable sheet S is configured as described above, and its usage will be described. 6 to 11 are perspective views showing the procedure for using the optical biological measurement sheet and the discard sheet.

  As shown in FIGS. 6 and 7, first, the sensor release sheet 12 attached to the lower surface of the sensor sheet 11 is peeled off. The sensor sheet 11 is attached to the upper surface of the disposable sheet S through the adhesive 11a on the lower surface of the sensor sheet 11.

  When the sheets 11 and S are stacked and pasted, the outer shape of the disposable sheet S and the outer shape of the sensor sheet 11 are matched.

  That is, the outer shapes of the central narrow portion 10 and the pasting central narrow portion 20 formed on each sheet 11 and S are matched.

  As shown in FIG.8 and FIG.9, after making each sheet | seat 11 and S into a sticking state by overlapping each other in this way, the sticking peeling sheet 22 of the lower surface of the disposable sheet S is peeled, and it is in a to-be-measured part. Fold it to the tip F1 of an index finger F and paste it.

  That is, the light emitting portion position marker 16 and the light receiving portion of the sensor sheet 11 are folded in half from the central folding line 11b of the sensor sheet 11 and attached to the front end F1 of the index finger F via the lowermost disposable sheet S. The position marker 17 is positioned on either the finger pad F2 or the finger back F3 of the index finger F, respectively.

  Further, the sensor code C is positioned at the position of the code marker 25 in order to attach and attach the sensor sheet 11 to the index finger F accurately.

  In this way, the sensor sheet 11 can be folded in two on the front end F1 of the index finger F and can be adhered accurately and closely.

  Next, the light emitting unit 13 and the light receiving unit 14 are energized to emit red LED light and infrared LED light from the light emitting unit 13, and the light receiving unit 14 receives these lights and analyzes the difference in wavelength with the biological monitor M. To measure oxygen saturation in the blood.

  After completion of the measurement, as shown in FIG. 10, the disposable sheet S attached integrally with the sensor sheet 11 is peeled off from the tip F <b> 1 of the index finger F, and then the ears for peeling the disposable sheet S from the sensor sheet 11. 28 is peeled off, only the disposable sheet S is disposed of, and the remaining sensor sheet 11 is re-adhered with the same prescription as described above, with the outer shape again attached and reused.

  However, since the sensor sheet 11 does not come into direct contact with the portion to be measured, the sensor sheet 11 can be used a plurality of times through the disposable sheet S, and there is no sanitary problem.

  As shown in FIG. 11, a sensor release sheet 12 is adhered to the adhesive surface of the sensor sheet 11 and stored as it is until the next time the blood oxygen saturation sheet A is used.

  For the light emitting element of the light emitting part, two types of light emitting elements were used so as to be able to emit two wavelengths. For example, when measuring mixed venous oxygen saturation, a light emitting part emitting one wavelength is used. It is configured to have two light receiving units, and the single wavelength light emitted from this light emitting unit is received by the two light receiving units, and the mixed venous oxygen saturation is calculated from the difference between the received lights. Also in the apparatus to measure, this sticking disposable sheet structure can be applied.

  As described above, some of the embodiments of the present invention have been described in detail with reference to the drawings. However, these are merely examples, and various embodiments can be made based on the knowledge of those skilled in the art including the aspects described in the section of the disclosure of the invention. The present invention can be implemented in other forms that have been modified or improved.
