- a first signal analyzer or a spectrum analyzer may be used to monitor the concentration of ingredients in the tissue through monitoring an induced signal from the tissue.
- the induced signal may not be from the ingredient itself
- the induced signal may also be from an aggregate of the ingredient with some other specific component, such as
- Aggregate ingredient (to be measured)+specific component.
- glucose and hemoglobin are used as an example.
- HbAlc (precursor) HbAlc

- a subject adaptor works better with an extruded tissue, such as a finger or toe. If there is a cone-shaped guide inside the subject adaptor, it guides the finger to anchor at the top of the cone-shaped guide in operation.

- U.S. applications Ser. Nos. 10/123,124 and 10/207,610
- There is a need to repeatedly measure the most important physiological parameters, such as blood sugar, blood oxygen and cholesterol, in order to monitor the variations thereof For such a purpose, it is provided with a first signal generator in the tissue, for example, a radio-isotope in the tissue emits a signal such as .alpha., .beta., .gamma. particles. Also, the signal can be an electromagnetic wave (visible light, UV, IR, X-ray, microwave) from outside the tissue. After the tissue is irradiated, absorption, scattering, fluorescence, etc., are induced in the tissue. A first signal analyzer or a spectrum analyzer may be used to monitor the concentration of ingredients in the tissue through monitoring an induced signal from the tissue. The induced signal may not be from the ingredient itself The induced signal may also be from an aggregate of the ingredient with some other specific component, such as
-
- In the invention, glucose and hemoglobin are used as an example.
-
- Before hemoglobin and glucose become a compound HbAlc, there is an intermediate stage of aggregate HbAlc (precursor). As the concentration of Hb is somewhat stable, the concentration of glucose in the blood may be figured out from the signal of HbAlc (precursor).
- To fix the tissue at the same position for sequential measurements, a subject adaptor is invented. The subject adaptor works better with an extruded tissue, such as a finger or toe. If there is a cone-shaped guide inside the subject adaptor, it guides the finger to anchor at the top of the cone-shaped guide in operation. To secure the finger in a stretched position and at the right angle, soft pads both above and below the finger can be used. These soft pads could be replaced with one or more elastic membranes which are stretched to wrap around the finger and hold the finger smoothly and softly so that no blood circulation is interfered. These pads or membranes can be in a concaved slot. The above entire structure is called the subject adaptor. One or more springs can be used to hold the subject adaptor to improve its adaptability.
- To keep the finger at the same position as the last measurement, a method to sense the position information of the finger is needed, and then this position information is used to move the finger back to the same relative position with respect to the first signal analyzer. Here a few remote sensing methods to sense the position of the finger are disclosed.
- The position of the finger is detected by changing signal intensity of a second signal by using a second signal generator and a second signal analyzer, and the second signal generator and the second signal analyzer can be mounted on the same side of the finger. The second signal generator generates and outputs the second signal to the finger. In this way, the second signal analyzer collects a scattered light from the finger. This scattered light changes along the finger due to natural marker such as a nail and a skin border. There will be a huge scattering light fluctuation due to irregular and anatomical structure. Or an artificial marker may be put somewhere along the finger which can be dark color, light reflection, or irregular surface, and all artificial markers will change the scattering light of the second signal significantly to be used to identify the position of the finger.
- The second configuration can be that the second signal generator and the second signal analyzer are at the opposite directions of the finger. The second signal generator and the second signal analyzer may rotate around the finger. A horizontal position is shown in
FIGS. 3 and 4 . When the finger tip starts to block the signal output from the second signal generator to enter the second signal analyzer, the position of the finger is known. - Further, using a see through window, this method uses image or direct eye contact to see the position of the finger, and then adjust the position of the finger to the same position as the last measurement. This structure is especially useful for a clamp like finger adaptor that has the first signal generator and the first signal analyzer, such as pulsatile oxygenometer that is used for measuring oxygen concentration in the blood. On the clamp, a see through window can be opened, so that the finger can be seen when the clamp is applied to the finger. There are scales on the see through window along side with the finger, so that where the finger is can be seen when the next measurement to make sure that the finger is at the same position according to the scale is made. This see through window is at the top of the clamp and is corresponding to the tip of the finger. When the clamp is put on the finger, where the finger tip is can be seen clearly. Because the first signal generator and the first signal analyzer are away from the finger tip, this see through window will not interfere with the mechanism of measuring the oxygen content. What needs to be done is cover this see through window with signal blocking cover, so that, no leaking signal will enter the clamp to interfere with readings of the finger adaptor.
- To improve the precision of positioning the finger, a patient's palm may be placed on a flat pad, so that the finger does not rotate due to incorrect posture.

FIGS. 1 and 2 respectively are a cross-sectional view and a top view of a first embodiment of the apparatus for monitoring a signal in situ of the present invention. The apparatus comprises a subject adaptor 1 for securing a subject for repeated measurements during repeated insertions. The subject adaptor 1 comprises aconcaved slot 2, multiplesoft pads 4, and a cone-shapedguide 5. Theconcaved slot 2 is made with a mold in the shape of an extruded tissue, here afinger 3. Theconcaved slot 2 and thefinger 3 are complementary in shape. Thesoft pads 4 are located inside theconcaved slot 2 and both above and below thefinger 3 so as not to interfere with signals. The cone-shapedguide 5 is located at the distal end inside theconcaved slot 2 to insure the correct position of thefinger 3. The apparatus further has afirst signal generator 6 and afirst signal analyzer 7. Thefirst signal generator 6 is positioned under thefinger 3, for generating a signal to be transmitted to a fixed position of thefinger 3 via a hole through the subject adaptor 1 and one of thesoft pads 4. Thefirst signal analyzer 7 is positioned opposite to thefirst signal generator 6 with respect to thefinger 3, for receiving and analyzing an induced signal from the fixed position of the finger 3 (i.e. for receiving and analyzing an induced signal from thefinger 3 in situ). Thefirst signal generator 6 and thefirst signal analyzer 7 are connected together in order to fix their relative position. The position of thefirst signal generator 6 and thefirst signal analyzer 7 may be exchanged. Therefore, thefirst signal analyzer 7 may be positioned under thefinger 3, and thefirst signal generator 6 may be positioned opposite to thefirst signal analyzer 7 with respect to thefinger 3. With the help of the cone-shapedguide 5, thefinger 3 can be fixed in order to make a new measurement on the fixed position of thefinger 3 where previous measurements were made. Thereby, repeated measurements, i.e. the so-called “monitoring,” could be made on the fixed position of thefinger 3 during repeated insertions of thefinger 3. It is pointed out in the invention that the induced signal used for composition analysis of a special ingredient is generated by the ingredient-making chemical actions with other ingredients in blood. - To improve the precision of positioning the
finger 3, a patient's palm may be placed on a flat pad, so that thefinger 3 does not rotate (nor tilt) due to incorrect posture to improve position fixing ability. Aposition fixing device 8 is disclosed. Theposition fixing device 8 uses a remote sensing tool to detect the position of the subject, and comprises a movingcomponent 9 to define the position of thefinger 3 precisely. The movingcomponent 9 is movably mounted on the subject adaptor 1. In the first embodiment of the apparatus, a terminal of the movingcomponent 9 is attached with asecond signal generator 10, asecond signal analyzer 11, and thefirst signal analyzer 7 as described above, and is positioned above thefinger 3 and moves relatively to thefinger 3. An opposite terminal of the movingcomponent 9 is attached with thefirst signal generator 6, and is positioned under thefinger 3. Besides, when the position of thefirst signal generator 6 and the position of thefirst signal analyzer 7 are exchanged, a terminal of the movingcomponent 9 above thefinger 3 is attached with thesecond signal generator 10, thesecond signal analyzer 11, and thefirst signal generator 7, and thefirst signal generator 6 is attached to the opposite terminal of the movingcomponent 9 under thefinger 3. Thesecond signal generator 10 generates a second signal, such as light, etc., to be transmitted to amarker 12. Themarker 12 can be a natural one such as an edge, a nail and skin border, or a wrinkle of thefinger 3, etc., or an artificial one painted or pasted on thefinger 3. When the second signal reflected from themarker 12 is detected by thesecond signal analyzer 11, the second signal informs the apparatus of the position of themarker 12. The apparatus then knows the precise position of thefinger 3 and thereby thefirst signal analyzer 7 attached to the movingcomponent 9 is moved to the position of the last measurement. In this way, the position of thefinger 3 may be positioned more precisely. - At the same time when the
second signal generator 10 is moving along thefinger 3, the second signal detected by thesecond signal analyzer 11 is recorded as a monitor to detect the rotation or tilt of thefinger 3 to further improve theposition fixing device 8. At the first measurement the second signals detected by thesecond signal analyzer 11, is recorded, this recorded second signals are compared with the second signals recorded for the following measurements. If significant difference between the second signals of the first measurement and the second signals of the following measurement is determined, thefinger 3 at the following measurement is not at the same position as the first measurement. - The moving
component 9 may be driven by a computer controlled motor. A computer saves a position of the last measurement and an original relation between the position of the last measurement and themarker 12. Thesecond signal analyzer 11 and the computer controlled motor are electrically connected to the computer via wired or wireless connection. Once, thesecond signal analyzer 11 detects a relation between the position of thefinger 3 and themarker 12, the computer compares the original relation and the relation detected by thesecond signal analyzer 11, and then the computer will instruct the computer controlled motor where to go. - With reference to
FIGS. 3 and 4 , a second embodiment of the present invention is same as the first embodiment ofFIGS. 1 and 2 . But, the movingcomponent 9 is only attached with thefirst signal generator 6 and thefirst signal analyzer 7. Thesecond signal generator 10′ and thesecond signal analyzer 11′ are around the tip of the finger, and at lateral position of the finger. Themarker 12 is the finger tip. In the second embodiment, thesecond signal generator 10′ and thesecond signal analyzer 11′ are mounted on two opposite sides of the cone-shapedguide 5, and are respectively positioned at two opposite sides of the finger tip. When thefinger 3 moves into theconcaved slot 2 and thefinger 3 blocks the signal output from thesecond signal generator 10′, the position of thefinger 3 is detected and known. Therefore, the movingcomponent 9 attached with thefirst signal generator 6 and thefirst signal analyzer 7 can be moved to the position of the last measurement of thefinger 3. - With reference to
FIGS. 5 and 6 , the subject adaptor 1 may be aclamp 16. The remote sensing tool further comprises a see throughwindow 13, such as a transparent window, withscales 14 mounted on an upper cover of theclamp 16 and anopaque cover 15, so that thefinger 3 may be fixed at the same position of the last measurement according to the see throughwindow 13 and thescales 14. Thefirst signal generator 6 is mounted on a lower cover of theclamp 16, and thefirst signal analyzer 7 is mounted on the upper cover of theclamp 16. Theopaque cover 15 is mounted on the upper cover of theclamp 16 and near the see throughwindow 13, and theopaque cover 15 is not transparent to the signals. After thefinger 3 is fixed at a right position, thisopaque cover 15 is closed to block the light from entering the inside of theclamp 16. This secures the accuracy of the measurements. In the third embodiment, theopaque cover 15 is a sliding lid.
