Description

Optical measuring device, optical measuring system and optical measuring method

technical field

The present invention relates to an optical measuring device, an optical measuring system and an optical measuring method, in particular to an optical measuring device, an optical measuring system and an optical measuring method for measuring the accommodating space of a syringe.

Background technique

People with type 1 diabetes secrete significantly less insulin than ordinary people, so insulin must be supplemented frequently. The insulin of type 2 diabetics can still maintain the daily requirement of normal people, so they can control their blood sugar goals through diet control or oral hypoglycemic drugs. However, as the patients grow older, the amount of insulin secreted by type 2 diabetic patients gradually decreases. Therefore, most elderly type 2 diabetic patients also need to be treated with insulin.

There are two ways to inject insulin. The first way is an insulin pump, which uses a microneedle implanted under the skin and a continuous blood glucose meter for monitoring and recording. It is suitable for type 1 and late type 2 diabetes patients. Generally, diabetic patients will choose the second method, using insulin medicine and a syringe (or insulin pen), to inject manually by themselves. Users can set the injection dose of the insulin pen and inject it directly into the subcutaneous tissue, but they need to record the injection dose by themselves for home medical follow-up care and outpatient follow-up treatment. In addition, because insulin preparations have storage and expiry date issues, they should be stored at 2 to 8°C when unopened; after opening, they must also be kept at 25 to 30°C, which can be stored for 4 to 6 weeks.

Therefore, diabetic patients need additional assistance in recording and managing injection doses. Specifically, diabetic patients need to clearly understand the time and dosage of their own injections, so as to avoid the danger of too much or too little insulin injection. In addition, it is also important to ensure that the insulin dosage is maintained within the storage temperature for use, so as to avoid patients injecting deteriorated insulin dosage.

The photo-sensing element is arranged on the opposite side of the light source element and receives the light emitted by the light source element. The transmission element is connected to and drives the light sensing element to measure the accommodating space of the syringe. Therefore, the light sensing element can dynamically measure the accommodating space of the syringe.

The processor controls the light source element and the transmission element and receives a sensing signal of the light sensing element, and calculates a measurement result of the accommodating space of the syringe according to the sensing signal. In addition, the display can display the measurement results, so that diabetic patients can know the injection dose and injection time in a timely manner. In addition, the display can display the last injection time and injection dose before use, so as to avoid repeated injections or forgotten injections.

Detailed ways

The direction of the present invention discussed here is an optical measuring device, an optical measuring system and an optical measuring method thereof. In order to have a thorough understanding of the present invention, detailed steps and structures will be presented in the following description. It is evident that the practice of the invention is not limited to specific details familiar to those skilled in the relevant art. In other instances, well-known structures or steps are not described in detail in order to avoid unnecessarily limiting the invention. The preferred embodiments of the present invention will be described in detail as follows, but in addition to these detailed descriptions, the present invention can also be widely implemented in other embodiments, and the scope of the present invention is not limited, and the scope of the patent claims thereafter is allow.

Hereinafter, the embodiments of the present invention are described in detail with reference to the accompanying drawings. The "embodiment", "this embodiment", "other embodiment" and so on mentioned in the description mean that the specific characteristics, configurations, or characteristics included in the embodiment of the present invention are described. The expression "in this embodiment" appearing in various places in the specification does not necessarily all refer to the same embodiment. When used in this specification, terms such as "measure", "receive", "calculate", "record", "judge", "transmit" or the like refer to the actions of a computer or computer system, or similar electronic computing devices or Processing, which manipulates or transforms data of a physical (such as electronic) quantity in a computer system's registers or memories into other similar physical quantities expressed in a computer system's memory, registers, or other such information storage, transmission or display means data. In addition, the elements described in the application claims of the present invention and the description of the invention are singular unless the number is specifically indicated. If the quantifier indicating an element is unity, the quantifier includes one unit or at least one unit. If there are multiple quantifiers to indicate a component, the quantifiers include more than two units.

In the embodiment shown in FIG. 1 , the optical measurement device 100 includes a body 9 , a light source element 10 , a light sensing element 20 and a transmission element 30 . In this embodiment, the body 9 includes at least one fixing slot 95 , which can receive and fix the syringe 90 . The optical measuring device 100 further includes a spring device (not shown in the figure), which is arranged in the fixing groove 95 and can be used to abut a syringe 90, so that the syringes 90 of different lengths are stably fixed in the fixing groove 95. one end. The light source element 10 is selected from the group consisting of laser and fluorescent lamps to provide a parallel light source or to form a parallel light source by a plurality of point light sources through filters. Since the light source element 10 is disposed on the fixing groove 95 or one side of the syringe 90 , part of the parallel light source will be blocked by some components of the syringe 90 and cannot reach the opposite side of the syringe 90 to be received by the light sensing element 20 . The "one side" mentioned here can mean that the light source element 10 is arranged on one side of the fixing groove 95 or that the light source element 10 is arranged on one side relative to the syringe 90. At this time, the light source element 10 can be used with or without contact. The mode is set on one side of the syringe 90.

As shown in FIG. 2 , the syringe 90 includes a plunger 91 and a housing 92 . The piston 91 is driven by the piston rod 93 so that the piston 91 can move back and forth. The piston 91 and the housing 92 form an accommodating space 94 , and the injection medicine is stored in the accommodating space 94 . In this embodiment, the syringe 90 is an insulin syringe, so the medicine stored in the accommodating space 94 is insulin. In order for the patient to understand the amount of medicine stored in the accommodating space 94 of the syringe 90 , the material of the casing 92 is generally designed to be transparent. In contrast, the material of the piston 91 and the piston rod 93 is designed to be opaque or opaque. As shown in the embodiment of FIG. 2 , when the light source element 10 provides a parallel light source (as shown by the arrow), the piston 91 and the piston rod 93 will block the light, so that the parallel light source cannot reach the other side of the syringe 90 .

As shown in the embodiment of FIG. 2, the light sensing element 20 is arranged on the opposite side of the light source element 10 (the other side relative to the syringe 90), and receives the light emitted by the light source element 10, because the piston 91 and the piston The rod 93 will shield the light, so the parallel light source of the light source element 10 cannot be received by the light sensing element 20 . In short, the light from the light source element 10 can only be measured when the light sensing element 20 is displaced to a position other than the piston 91 and the piston rod 93 . When the light sensing element 20 measures the light, the junction position between the piston 91 and the accommodating space 94 can be obtained according to the displacement distance of the light sensing element 20, and then the volume of the accommodating space 94 can be calculated to automatically obtain the remaining medicine. dose. In this embodiment, the light sensing element 20 is generally designed to receive a specific wavelength of the light emitted by the light source element 10 . In addition, in this embodiment, the light sensing element 20 can be designed as a corresponding light source sensing element in response to different light source elements 10, so the light sensing element 20 can be selected from photodiodes, photoelectric crystals, photoresistors, charge-coupled elements, and A group composed of complementary metal oxide semiconductors.

In the embodiment shown in FIG. 2 , the light sensing element 20 is connected to the transmission element 30 . The transmission element 30 includes a screw 31 and a motor 32 . The motor 32 is connected to and drives the screw rod 31. Since the light sensing element 20 is arranged on the transmission element 30, the light sensing element 20 will advance or retreat along the axial direction (X direction) of the screw rod 31, so that the transmission element 30 is connected and The light sensing element 20 is driven. Therefore, the motor 32 can directly or indirectly drive the light sensing element 20. Here, "directly" means that the light sensing element 20 is arranged on the motor 32; and "indirectly" here means that the light sensing element is arranged on the receiving motor 32. driven components. In this embodiment, the motor 32 is selected from the group consisting of a stepping motor, an AC motor, a DC motor, an ultrasonic motor and a linear motor, preferably a stepping motor. Since the minimum step size of the stepping motor is about 0.5 to 20 microns, the present invention can provide a more precise resolution of about 0.5 to 20 microns. This is because the displacement of the light sensing element 20 in the X direction is between 0.5 and 20 microns, and the effective injection length of a general insulin syringe is 36 mm, which is divided into 300 units, and the smallest unit is about 120 microns. Therefore, The resolution provided by the present invention allows the smallest units to be identified. Through this design, the transmission element 30 can be connected to and precisely drive the light sensing element 20, and accurately measure the junction position between the accommodating space 94 and the piston 91, so as to provide accurate recording of the remaining dose.

In the embodiment shown in FIG. 2 , in order to measure two syringes 90 , the present invention provides two sets of light source elements 10 , and light sensing elements 20 are also arranged on both sides of the screw 31 . However, the present invention may also include only one set of light source elements 10 , and a single light sensing element 20 is disposed on one side of the light source element 10 for accurate measurement. In the embodiment shown in FIG. 2 , the light source element 10 can be a parallel light source or a parallel light source formed by a plurality of point light sources through filters. Compared with the embodiment shown in FIG. 3 , the light source elements 10a, 10b can be a point light source or a plurality of point light sources selected from the group consisting of light emitting diodes (LEDs), halogen lamps and cold cathode lamps. The liquid contained in the accommodating space 94 will produce scattered light after being irradiated by the light source element 10a. Therefore, the light source element 10a does not have to be disposed close to the accommodating space 94 or a plurality of point light sources to make the accommodating space 94 bright. Since the light source element itself usually generates heat, the temperature of the light source element is not conducive to the preservation of the medicament (such as insulin) stored in the accommodating space 94 . Through the design of the light source element 10 a , the light source element 10 a does not have to be adjacent to the accommodating space 94 , and light can also enter the accommodating space 94 surrounded by the casing 92 . After the scattered light enters the accommodating space 94 , the light will be reflected in the casing 92 of the accommodating space 94 , so the accommodating space 94 will be in the form of light transmission, which is helpful for the light sensing element 20 to measure. In addition, in the embodiment shown in Fig. 3, the present invention sets two kinds of light source elements 10a and light source elements 10b, but in other variant embodiments (not shown in the figure), the present invention can also only set a single light source element 10a, a single light sensor Measuring element 20 and transmission element 30.

The sectional view of the sectional line A-A' of the embodiment in FIG. 2 is shown in FIG. 4 . The light source element 10 is disposed on both sides. The transmission element 30 includes a mover 33 in addition to the motor 32 and the screw 31 shown in FIG. 2 . The mover 33 includes a threaded portion 331 and a body portion 332 . The threaded portion 331 is threaded to the screw 31 , and the body portion 332 is connected to the threaded portion 331 , so the body portion 332 can move together with the threaded portion 331 . Since the light sensing element 20 is disposed on one side of the body portion 332 , the light from the light source element 10 will pass through the syringe 90 and be received by the light sensing element 20 . Generally speaking, the signal of the light sensing element 20 can be transmitted by wires, but the present invention belongs to dynamic measurement, and the wires may hinder the displacement path, so as shown in FIG. The metal dome 333 can contact the bump 41 under the printed circuit board 40 to be electrically coupled, so as to transmit the signal of the light sensing element 20 . In addition, when the screw 31 is driven by the motor, the mover 33 may be affected by the screw 31 to rotate. In order to avoid the above-mentioned rotation effect, because the printed circuit board 40 is fixed on the mover 33 without displacement, when the metal dome 333 interferes When the bump 41 is turned, the bump 41 will exert a positive force on the mover 33 through the metal elastic piece 333 to prevent the mover 33 from rotating. As shown in the embodiment of FIG. 4, the transmission element 30 further includes a wheel shaft 35, and the wheel shaft 35 is arranged under the mover 33. Specifically, the wheel shaft 35 is arranged under the body portion 332 of the mover 33 for the mover 33. Sliding is not limited by friction, so the bottom of the mover 33 can form a low friction contact surface or metal surface to facilitate the mover 33 to slide.

As shown in FIG. 5 , which is a top view of another embodiment, an optical measuring device 100' includes a light source element 10', a light sensing element 20' and a transmission element 30'. In this embodiment, the light source element 10' is a point light source selected from the group consisting of light emitting diodes (LEDs), halogen lamps and cold cathode lamps. Since the mover 33' connects the light source element 10' and the light sensing element 20', when the motor 32' of the transmission element 30' is driven, the light source element 10' and the light sensing element 20' will move in the X direction or in the opposite direction together. Measurements are made while shown in Figure 5. As shown in FIG. 5 , when the mover 33 ′ moves to a region other than the piston 92 and the piston rod 93 , the light emitted by the light source element 10 ′ will pass through the casing 92 and be received by the light sensing element 20 ′. However, the above-described embodiment may be changed into a modified embodiment as shown in FIG. 6 . In a variant embodiment, the positions of the light source element 10' and the light sensing element 20' can be interchanged, so the light is emitted from the middle (indicated by the arrow), and this design can reduce the use of point light sources and achieve energy saving. In addition, it can avoid the high sensitivity of the light sensing element 20 ′ in FIG. 5 from detecting the light emitted by other groups of light source elements 10 ′.

The sectional view of the section line B-B' of the embodiment of Fig. 5 is shown in Fig. 7. In the embodiment shown in Fig. 7, the mover 33' of the transmission element comprises a threaded part 331', a body part 332' and a wing part 333 '. The threaded portion 331 ′ is screwed to the screw 31 , and the light sensing element 20 ′ is disposed on one side of the body portion 332 ′, and the light source element 10 ′ is disposed on the side of the wing portion 333 ′ opposite to the light sensing element 20 ′. Therefore, the light source element 10 ′ and the light sensing element 20 ′ can be connected by the mover 33 ′, and can move forward and backward as a whole along the X direction. In the embodiment shown in Fig. 7, although two sets of light sensing elements 20' and light source elements 10' are shown, the present invention may only contain one set of light sensing elements 20' and light source elements 10' to achieve the functions of the present invention . As shown in the embodiment of Figure 7, the transmission element further includes a wheel shaft 35, and the wheel shaft 35 is arranged under the mover 33'. Down, so that the mover 33' slides without being limited by friction. Therefore, the bottom of the mover 33' can form a low-friction contact surface or metal surface to facilitate the slide of the mover 33'.

As shown in FIG. 7 , the upper surface 34 ′ of the mover 33 ′ is provided with a metal elastic piece 334 ′, and the metal elastic piece 334 ′ can resist the bump 41 under the printed circuit board 40 and be electrically coupled. When the screw rod 31 is driven by the motor, the mover 33' may be affected by the screw rod 31 to rotate. In order to avoid the above-mentioned rotation effect, because the printed circuit board 40 is fixed on the mover 33' without displacement, when the metal dome 334 When the bump 41 collides, the bump 41 will exert a positive force on the mover 33 ′ through the metal elastic piece 334 ′, so as to prevent the mover 33 from rotating. At the same time, the bump 41 and the metal dome 334 ′ can transmit the signal of the printed circuit board 40 to the mover 33 ′ through the electrical connection of the two, so as to prevent the displacement path of the mover 33 ′ from being restricted by the circuit.

In addition, as shown in another embodiment of FIG. 8 , the optical measurement device 100 a includes a light source element 10 , a light sensing element 20 a and a transmission element 30 a. In this embodiment, the transmission element 30a includes a toothed belt 31a and a motor 32a. As shown in FIG. 9 , the motor 32a has a drive shaft 322a, and a gear 323a is provided at one end of the drive shaft 322a, and the gear 323a is detachably engaged with the toothed belt 31a. As shown in Figure 8, since the photosensitive element 20a is arranged on the motor 32a and the toothed belt 31a is fixed on the body 9, when the motor 32a is driven, the motor 32a can be displaced on the toothed belt 31a so that it is set on the toothed belt 31a. The light sensing element 20a on the motor 32a is displaced and measured. Specifically, in the embodiment shown in Figure 10, the motor 32a is connected to the body portion 332 of the mover 33, and the light sensing element 20a is arranged on one side of the body portion 332, so when the motor 32a is connected to the toothed belt When moving on 31a, the light sensing element 20a can be driven by the motor 32a to move. However, in another embodiment as shown in FIG. 11 , the optical measurement device 100b includes a light source element 10 , a light sensing element 20a and a transmission element 30b. The transmission element 30b includes a toothed belt 31a and a motor 32b. Since the light sensing element 20a is disposed on the toothed belt 31a, when the motor 32b drives the toothed belt 31a, the motor 32b does not move but the toothed belt 31a moves. As the toothed belt 31a moves, the light sensing element 20a disposed on the toothed belt 31a will be simultaneously driven to perform dynamic measurement. Specifically, as shown in the embodiment of FIG. 12 , the motor-driven toothed belt 31 a is connected to the main body 332 of the mover 33 , and the light sensing element 20 a is disposed on one side of the main body 332 . When the position of the motor is fixed and the motor drives the toothed belt 31a to move relatively, since the light sensing element 20a moves synchronously with the body part 332 and the toothed belt 31a, the light sensing element 20a can move dynamically for measurement. Compared with the embodiment of FIG. 10 and the embodiment of FIG. 12 , the motor 32b can be fixed on one side, so that the power lines of the motor 32b will not interfere with each other due to displacement. In addition, the motors 32a, 32b of the embodiment of FIG. 12 and the embodiment of FIG. 10 are selected from the group consisting of stepping motors, AC motors, DC motors, ultrasonic motors and linear motors.

As shown in another embodiment of FIG. 13 , the optical measurement device 130 includes a body 131 , a light source element 132 , a light sensing element 133 and a transmission element 134 . In this embodiment, the body 131 includes at least one support portion 1311 , and the support portion 1311 can support the above-mentioned syringe 90 . In this embodiment, the supporting portion 1311 can form a fixing groove for supporting the syringe 90, so the fixing groove is not limited to a solid groove, but can be a hollow groove as described in the embodiment of FIG. 13 .

In the embodiment shown in FIG. 14 , the transmission element 134 includes a screw 1341 and a motor 1342 , and the motor 1342 drives the screw 1341 . In addition, the transmission element 134 further includes a mover 33a, as shown in FIG. 15 . The mover 33a of the transmission element 134 includes a threaded portion 331a, a body portion 332a, a first rib 333a and a second rib 333b. In the embodiment of FIG. 15 , the body portion 332 a includes a through hole 334 , and the body 131 (refer to FIG. 13 ) further includes a fixing rod 1312 . The fixing rod 1312 passes through the through hole 334, and the threaded portion 331a is threaded to the screw rod 1341 (refer to FIG. 13 ). When the mover 33a moves, the mover 33a is constrained by the fixed rod 1312 and the screw rod 1341, so when the mover 33a moves along the axial direction (x) of the screw rod 1341, the mover 33a will not rotate arbitrarily. In other embodiments (not shown), the screw rod 1341 and the threaded portion 331a can be replaced by a combination of a toothed belt and a motor.

As shown in FIG. 15 , the body portion 332a includes a first end 3321 and a second end 3322 . A first protruding rib 333 a protrudes from a side of the first end 3321 , and a second protruding rib 333 b protrudes from a side of the second end 3322 , and the first protruding rib 333 a is disposed opposite to the second protruding rib 333 b. In this embodiment, since the light source element 132 is disposed on the second rib 333b, and the light sensing element 133 is disposed on the first rib 333a, the light source element 132 corresponds to the light sensing element 133 .

The activation sensor can determine whether to transmit the activation signal to the processor 520 according to the state of the optical measurement system 500 (eg, the position of the syringe). Specifically, the activation sensor of the sensor 600 can detect whether the optical measurement system 500 is maintained in a condition suitable for measurement. Generally speaking, a closed and dark environment is conducive to optical measurement, such as the cover body and the optical measurement device 510. The measurement will only be performed when the body is closed. At this time, the start sensor of the sensor 600 is a limit switch (limit switch), which can be used to detect a small stroke and control the switch. The start sensor of the sensor 600 can be used according to different Designed to be set on the cover or body respectively. Therefore, when the cover and the body are closed, the activation sensor of the sensor 600 can be triggered. In other embodiments, even if the cover and the body are closed, if no syringe 90 is placed in the fixing slot 95 , the transmission element will not be driven. Therefore, in this embodiment, when the cover is opened, the syringe 90 is inserted into the body from above the body. Referring again to the embodiment of FIG. 13 , the syringe 90 is inserted into the fixing groove of the body 131 through the installation hole 1313 of the body 131 , so the syringe 90 can also be placed into the body 131 laterally.

In this embodiment, the activation sensor (not shown in the figure, such as a limit switch) of the sensor 600 can be arranged on the push rod 1314 or on the body 131 opposite to the push rod 1314, so that when the push rod 1314 and the body 131 When the activation sensor of the sensor 600 is touched, the transmission element 134 will drive the light source element 132 and the light sensing element 133 to measure the syringe 90 . In addition, in the embodiment shown in FIG. 17, the sensor 600 may include a photo interrupter, and the photo interrupter may be activated according to the position of the light sensing element 133 (such as the position of the mover) to determine whether The return signal is transmitted to the processor 520 , which can prevent the light sensing element 20 from moving beyond the measurement range or idling at the end of the screw 31 . Specifically, the interruption sensor is used to define an effective measurement range, and can be disposed on one side of the accommodating space 94 (for example, disposed outside the piston rod 93 of the syringe 90 ). The interruption sensor is mainly divided into two elements (light-emitting element and light-receiving element), so the interruption sensor can be set in two ways of transmission type and reflection type, and the interruption sensor can be arranged outside the piston rod 93 of the syringe 90 to perform Sensing, for example, in the transmissive embodiment, for example, in the transmissive embodiment, when the mover 33 moves between the light-emitting element and the light-receiving element to block the light-receiving element from receiving the signal, the mover will receive the signal and turn back. In the reflective embodiment, when the mover 33 moves to the sensing position of the light-emitting element and the light-receiving element to reflect the light signal of the light-emitting element to the light-receiving element, the mover will receive the signal and turn back.

In addition, the button 610 of the optical measurement system 500 can be used by the user to transmit a user instruction to the processor 520 .

The present invention provides an optical measuring method, which can use the light source element 10 , the light sensing element 20 and the transmission element 30 as described in the embodiment of FIG. 2 . This optical measurement method utilizes the transmission element 30 to drive the light sensing element 20, so that the light sensing element 20 moves and measures at the same time, and directly finds the junction position between the accommodating space 94 and the piston 91, which can be achieved by means of multiple averages. reduce mistakes. If during moving measurement, light sensing element 20 all detects light from beginning to end, then judge that there is no syringe 90 in the fixed groove 95, do not measure; If light sensing element 20 all can't detect light from beginning to end, then judge The syringe has been used up and the user is prompted to replace it. In this optical measurement method, the driving method of the transmission element 30 is simple, so no complicated design is required.

When carrying out the above-mentioned optical measurement, since the motor drive and the optical detection are carried out at the same time, it is very likely that the displacement error caused by the overspeeding of the motor displacement will occur. Therefore, the present invention provides another optical measurement method, using the implementation shown in Figure 2 The light source element 10 , the light sensing element 20 and the transmission element 30 are described as examples. The flow chart of the optical measuring method of the present invention is shown in Figure 18, comprises the following steps: In step 1410, preset a measuring distance, this preset measuring distance is at least two of the length of filling or remaining accommodating space 94 One-third, execute step 1420; in step 1420, drive the light sensing element 20 from one end of the accommodating space 94 to the measurement distance, and define the transmission direction as positive (in this embodiment, the X direction The opposite direction of the positive direction), and the opposite direction of the positive direction is the negative direction (in this embodiment, the X direction), wherein each time the measurement distance is 1/2 of the previous measurement distance, step 1430 is executed; in step 1430 In step 1440, if the light from the light source element 10 is received, the light sensing element 20 is forwardly driven to 1/2 of the previous measurement distance; and, in step 1450, if no light from the light source element 10 is received, drive the light sensing element 20 in the negative direction to 1/2 of the previous measurement distance . In the embodiment shown in FIG. 19 , step 1410 further includes step 1411 of driving the light sensing element 20 to one end of the accommodating space 94 (specifically, the fixed end or the piston end of the syringe). Step 1411 also includes setting a label 96 at the fixed end of the accommodating space 94, and driving the light sensing element 20 to the label 96 in step 1412; step 1411 also includes judging whether the light sensing element 20 receives the light source In the step 1413 of the light emitted by the component 10, for example, when the received signal changes from signal to no signal, it can be determined that the light has reached one end (fixed end or piston end) of the accommodating space 94 . Step 1411 is to utilize the syringe 90 itself to define a measurement reference point first, and the advantage of this is that if the measurement reference point cannot be found, the measurement will not be performed (there is no syringe 90 placed in the fixed groove 95), and further the syringe 90 can be prevented. False detection due to different placement or orientation.

In addition, the light receiving judging step 1430 of the present invention further includes a step 1460: preset a threshold value, at this time, the judgment value is the number of times the transmission element 30 moves repeatedly, and when the judgment value is greater than the threshold value, the transmission element 30 stops ( does not start). In other embodiments, the light reception judging step 1430 may also include step 1470: set the transmission element 30 to have a step range, and the judgment value at this time is the measured distance of the transmission element 30, if the measured distance is less than the step range , the transmission element 30 stops (does not start).

A specific example of the above steps is shown in Figure 20. In this embodiment, a label 96 is arranged at the fixed end of the accommodating space 94, and the label 96 can shield the light emitted by the light source element 10, so that the light sensing element 20 cannot receive The light emitted by the light source element 10; however, in other embodiments, because the needle itself can also shield the light emitted by the light source element 10, there is no need to set any label 96; in addition, if the light sensing element 20 reaches the accommodating space 94 piston end, because the piston itself also shields the light emitted by the light source element 10; therefore when the light sensing element 20 can receive and cannot receive the light emitted by the light source element 10, the present invention determines that the light sensing element 20 is located at one end (fixed end or piston end) of the accommodating space 94 . In this embodiment, the light sensing element 20 is moved forward by a unit of a first measurement distance (not limited to the measurement distance in FIG. 20 ) from the fixed end of the accommodating space 94, and no light is detected at this time ( marked as 0), because the piston 91 shields the emitted light from the light source element 10 . Therefore, the photo-sensing element 20 is driven in the negative direction (X direction) to half of the first measuring distance unit (the second measuring distance). At this time, the light sensing element 20 receives the light from the light source element 10 (marked as 1), so the light sensing element 20 moves the light sensing element 20 forward to one-half of the second measuring distance unit (the third measuring distance). At this time, the light sensing element 20 receives the light from the light source element 10 (marked as 1), so the light sensing element 20 moves the light sensing element 20 forward to one-half of the third measurement distance unit ( fourth measurement distance). The above-mentioned steps are repeatedly and accurately obtained for the boundary position between the piston 91 and the accommodating space 94 , and then the medicament content ΔV in the accommodating space 94 is accurately calculated. Wherein the above-mentioned times of repeated movement can be preset as a threshold value, and if the judgment value is greater than the threshold value, the transmission element 30 stops (does not start). In addition, in other embodiments, the transmission element 30 can also be set to have a step range, and if the measured distance of the transmission element 30 is smaller than the step range, the transmission element 30 stops (does not start).
