As shown in fig. 1 and 2, the sensing electrode 121 according to the present disclosure may specifically be a working electrode of the glucose sensor 120, but the present embodiment is not limited thereto, and the sensing electrode 121 may be applied to monitoring electrodes of other physiological parameters, for example, uric acid detection sensors that can be used for detecting uric acid, cholesterol monitoring sensors that can be used for detecting cholesterol, and the like, and it is only necessary to replace the sensitive reagent in the sensing electrode 121 with a corresponding enzyme that specifically reacts with its target analyte. In addition, besides the dispensing of the sensing electrode 121, the method of positioning and identifying the dispensing location by machine vision in the present disclosure is also applicable during other manufacturing processes requiring automatic dispensing. In some examples, the dispenser 21 may dispense glucose-sensitive reagents. In other examples, the dispenser 21 may dispense something other than a glucose-sensitive reagent, such as a semipermeable membrane solution, or the like.

In the present embodiment, the dispensing apparatus 1 of the sensing electrode 121 according to the present disclosure may include a loading device 10, a dispensing device 20, a positioning device 30, and an identification device 40. The loading device 10 may be loaded with the sensing electrode 121 in a predetermined area. The dispensing device 20 may be provided on the loading device 10 and movable relative to the loading device 10, the dispensing device 20 having a photographing device (not shown) and a dispenser 21 for dispensing at least the sensing electrode 121 to form a sensing layer. The positioning device 30 may be configured to read a configuration file comprising electrode parameters and indicating a prescribed area, and move the drip coating device 20 to above the prescribed area according to the configuration file, whereby the photographing apparatus photographs the sensing electrode 121 to obtain an area image 31 comprising the sensing electrode 121. The recognition means 40 may be configured to acquire the area image 31 and recognize the electrode shape of the sensing electrode 121 in combination with the electrode parameters, acquire the center position of the electrode shape as a target coordinate according to the electrode shape, and control the drip coating device 20 to move above the target coordinate to perform a drip coating operation.

In the present disclosure, the sensor electrode 121 can be loaded by the loading device 10, the positioning device 30 controls the dispensing device 20 to move to a predetermined area loaded with the sensor electrode 121 to take a region image 31, and finally the recognition module recognizes the target position of the sensor electrode 121 in the region image 31 by machine vision and controls the dispensing device 20 to move to the target position to perform dispensing, in which case the dispensing apparatus 1 can perform a dispensing operation on the sensor electrode 121 by cooperative engagement between the devices, thereby enabling an improvement in the degree of automation of the dispensing operation.

In some examples, the dispensing device 1 may have an external device 3 and an operating device 2. Specifically, the external device 3 may include the positioning device 30 and the recognition device 40, and the operating device 2 may include the loading device 10 and the drip coating device 20.

In some examples, the external device 3 may include at least one of a computer, a mobile communication device, or a cloud server. In other examples, the positioning device 30 may be implemented as a computer program for positioning. In other examples, the identification means 40 may be embodied as a computer program for identification.

Fig. 3 is a schematic diagram showing the structure of the operation device 2 of the dispensing device 1 according to the embodiment of the present disclosure.

As shown in fig. 3, in the present embodiment, the loading device 10 may be loaded with the sensing electrode 121 in a predetermined area. Thus, the dispenser device 20 can dispense the sensor electrode 121 mounted on the loader 10. In some examples, the loading device 10 may be loaded with a drip coating device 20. In other examples, the loading device 10 may have a stand for supporting the drip application device 20. Thus, the drip coating device 20 can be arranged on the support of the loading device 10. Additionally, in some examples, the loading device 10 may be combined with a drip coating device 20. In this case, a good fit can be formed between the loading device 10 and the drip coating device 20, whereby the accuracy and stability of the drip coating operation can be improved.

Fig. 4 is a schematic diagram showing the structure of the sensing electrode array plate 12 of the dispensing apparatus 1 according to the embodiment of the present disclosure.

As shown in fig. 4, in some examples, the loading device 10 may be arranged with a sensing electrode array plate 12 including sensing electrodes 121. Thus, the sensing electrode 121 can be mass-dropped. In some examples, the sensing electrode array plate 12 may be made of a flexible substrate. In other examples, the flexible substrate may be composed of an insulating material. Specifically, the insulating flexible substrate material may be at least one of Polyimide (PI), polyethylene terephthalate (PET), parylene (Parylene), silicone, polydimethylsiloxane (PDMS), polyethylene glycol (PEG), or polytetrafluoroethylene resin (Teflon), polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene naphthalate (PEN), or the like. This allows the sensing electrode 121 to have both flexibility and insulation properties, and can reduce discomfort after implantation into the body.

In other examples, the sensing electrode array plate 12 may be made of a non-flexible substrate. Specifically, the inflexible substrate material may be ceramic, polymethyl methacrylate (PMMA), alumina, silica, or the like. In this case, the sensing electrode 121 may have excellent supporting performance. In addition, the sensing electrode 121 may be coupled with a rigid substrate, such as a rigid needle tip, and the sensing electrode 121 may be implanted in a body surface (e.g., shallow skin, etc.) without the need for an auxiliary implantation device (not shown), such as a needle assist device.

In some examples, the sensing electrode 121 may be formed on a flexible substrate, thereby forming the sensing electrode array plate 12. Additionally, in some examples, the flexible substrate may be a transparent substrate. In this case, the transparent substrate can highlight the shape and color of the sensing electrode 121, and thus, the reliability of recognition positioning by the positioning device 30 (described later) and the recognition device 40 (described later) can be improved.

In some examples, the sensing electrode 121 may be formed on the flexible substrate through a MEMS process, a photolithography process, an etching process, or the like. Thereby, the sense electrode array plate 12 can be mass-produced to mass-produce the sense electrodes 121.

In some examples, the loading device 10 is provided with a vacuum seat 11 having a plurality of holes 111 at a prescribed region, the vacuum seat 11 being for adsorbing the sensing electrode array plate 12 to fix the sensing electrode 121. In this case, the air pressure of the sensor electrode array plate 12 located at one side of the vacuum seat 11 will be smaller than the air pressure at the other side, whereby the sensor electrode array plate 12 can be stably fixed to the surface of the vacuum seat 11 by the air pressure.

In some examples, the holes 111 may be arranged at an edge of the vacuum seat 11. In this case, the edge of the sensing electrode array plate 12 can be adsorbed through the hole 111 arranged at the edge of the vacuum seat 11, whereby the influence of the negative pressure on the sensing electrode 121 in the sensing electrode array plate 12 can be reduced.

In other examples, the loading device 10 may have a clamp for clamping the sensor electrode array plate 12. Thereby, the sensor electrode array plate 12 can be further fixed, thereby improving the stability of the sensor electrode array plate 12 at the time of the dispensing operation.

In some examples, the loading device 10 may further include a vacuum pump for maintaining the vacuum seat 11. Thereby, the suction force of the vacuum chuck 11 to the sensor electrode array plate 12 can be adjusted by the vacuum pump.

In some examples, the loading device 10 may also have a reference portion for acquiring the coordinate information and the scale information in the area image 31 as a reference for the recognition device 40. In some examples, the reference may be a pattern on the sensing electrode array plate 12. In other examples, the reference may be a pattern on the vacuum seat 11. In this case, the positioning device 30 and the recognition device 40 can easily obtain the coordinate information and the scale information in the area image 31 from the reference portion, and thus, the recognition efficiency can be improved.

In some examples, a groove for guiding dispensing may be provided on the sensing electrode 121. In this case, the grooves can restrict the content of the dispensing by the dispenser 21, whereby the accuracy of the dispensing can be better controlled. In other examples, the groove may serve as a reference. Thereby, the positioning device 30 and the recognition device 40 can easily derive the coordinate information and the scale information in the area image 31 according to the size scale of the groove.

In some examples, the loading device 10 may be a closable space and the drip application device 20 may be disposed within the closed space. In this case, the closed space may be filled with an inert gas, whereby the possibility of oxidation reaction of the glucose-sensitive reagent with the components in the air can be reduced. In other examples, the drip coating device 20 may be filled with different composition, different pressure gases. Thus, a plurality of different dispensing environments can be manufactured, and thus, the dispenser can be adapted to different types of dispensing.

In this embodiment, the drip coating device 20 may be disposed on the loading device 10 and movable relative to the loading device 10.

In the present embodiment, the drip coating device 20 may have a photographing device and a drip coater 21 for performing drip coating at least on the sensing electrode 121 to form a sensing layer. In this case, the drip coating device 20 can photograph the region where the sensing electrode 121 is located by the photographing apparatus, and can drip-coat the sensing electrode 121 by the drip coater 21, whereby the efficiency of the drip coating device 20 can be improved.

In some examples, the capture device may be a miniature video camera, an optical camera, a digital camera, or the like. In some examples, the photographing device may be mounted at a side of the dispenser 21. In other examples, the photographing apparatus may be provided independently. Thereby, the photographing apparatus can be more flexibly manipulated. In addition, in some examples, the photographing device may be combined with the dispenser 21. Thereby, it is possible to provide a unified operation of the drip applicator 21 and the photographing device, thereby improving portability of the drip application device 20 operation. In other examples, the drip coating device 20 may have an Automated Optical Inspection (AOI) probe.

In some examples, the drip applicator 21 is configured to move in a horizontal direction and in a vertical direction. Thereby, the position of the dispenser 21 can be adjusted as needed. In some examples, the coordinates on the dispenser 21 closest to the nearest end of the sensing electrode 121 are the coordinates of the dispenser 21. Thereby, the accuracy of dispensing by the dispenser 21 can be improved. In other examples, the dispenser 21 may be needle-shaped (see fig. 3). Thus, micro-dispensing can be performed on the sensing electrode 121.

Fig. 5 is a schematic diagram showing an area image 31 captured by the drip coating device 20 of the drip coating device 1 according to the embodiment of the present disclosure.

As shown in fig. 5, in the present embodiment, the positioning device 30 may be configured to read a configuration file including electrode parameters and indicating a prescribed area. In this case, the execution content of the positioning device 30 can be further controlled by encoding the configuration file, whereby the positioning device 30 can be controlled by the configuration file encoded in advance. In some examples, the configuration file may be a location matrix file, an industrial coordinate file, a database file, an image data file, or a text file. In other examples, the dispensing device 1 may have translation means. In particular, the translation means may read the configuration file through a dedicated interface and reconstruct the logic of the configuration file, thereby enabling the positioning means 30 or the identification means 40 to execute the instructions in the configuration file. In this case, the translating device can translate various configuration files, thereby improving the compatibility of the dispensing device 1 to various configuration files and improving the flexibility of controlling the dispensing device 1. Additionally, in some examples, various types of configuration files may be read by way of a plug-in. Thus, the reading range of the configuration file can be enlarged.

In some examples, the translation device may be implemented by a translation program written based on a cross-platform computer programming language (python).

In the present embodiment, the positioning device 30 may move the drip coating device 20 to above a prescribed area according to the configuration file, so that the photographing apparatus can photograph the sensing electrode 121 to obtain the area image 31 including the sensing electrode 121. In some examples, the prescribed area may be an area where any one of the sensing electrodes 121 is located on the sensor array plate. Thereby, the region image 31 including the sensing electrode 121 can be completely acquired.

In some examples, the configuration file may include coordinate information to move the dispenser 21 to an initial position, as well as length, width, and spacing information between the sensing electrodes 121 of the array of sensing electrodes 121 in the sensing electrode array plate 12. In this case, the positioning device 30 and the recognition device 40 can control the dispensing device 20 to perform a dispensing operation one by one on each of the sensing electrodes 121 in the array of sensing electrodes 121 according to the configuration file, whereby the sensing electrodes 121 can be dispensed in batches.

In some examples, the array of sense electrodes 121 may be disposed on the sense electrode array plate 12 in a rectangular array. In other examples, the array of sensing electrodes 121 may be disposed on the sensing electrode array plate 12 in the form of a parallelogram, triangle, polygon, or circular array. Thus, different positioning methods can be set according to the shapes of the different arrays of the sensing electrodes 121.

In other examples, the configuration file may include coordinates of each of the sense electrodes 121 in the sense electrode array plate 12. Thereby, the positioning device 30 can accurately move the dispenser 21 to the position of each of the sensor electrodes 121. Additionally, in some examples, when the array of sense electrodes 121 is a rectangular array, the configuration file may include at least the coordinates of any of the four corners of the array of sense electrodes 121. Specifically, the positioning device 30 finds coordinates of any one of the four corners according to the configuration file, and sequentially positions and photographs the sensing electrodes 121 in the sensing electrode 121 array according to the length and width of the sensing electrode 121 array in the configuration file and the interval information between the sensing electrodes 121, so that the area images 31 of the sensing electrodes 121 can be obtained in batches.

In some examples, the dispensing device 1 may comprise a correction means that adjusts the distance between the dispenser 21 and the prescribed area based on the area image 31 captured by the photographing device such that the area image 31 comprises a complete image of the sensing electrode 121. This ensures that the region image 31 satisfying the requirements of the positioning device 30 is captured.

In the present embodiment, the recognition means 40 may be configured to acquire the area image 31 and recognize the electrode shape of the sensing electrode 121 in combination with the electrode parameters. In this case, the accuracy with which the recognition device 40 recognizes the electrode shape of the sensing electrode 121 can be adjusted by adjusting the electrode parameters in the configuration file, whereby the electrode shape of appropriate accuracy can be obtained as needed. Specifically, the recognition device 40 may be implemented as a machine vision program. In this case, the relevant morphological information can be obtained from the area image 31, converted into a digitized signal based on the pixel distribution, luminance, color, and other information of the area image 31, and subjected to various operations to obtain the target feature. In other examples, the positioning device 30 may also be implemented as a machine vision program.

In some examples, the electrode parameters may include at least one of a size, shape, or thickness of the sensing electrode 121. Thereby, the recognition means 40 can recognize the sensing electrode 121 in the area image 31 from the electrode parameters and perform fitting of the shape to obtain the electrode shape.

In the present embodiment, the recognition device 40 may acquire the center position of the electrode shape as the target coordinates from the electrode shape, and control the dripping device 20 to move above the target coordinates to perform the dripping operation.

In some examples, the identification device 40 may obtain coordinate information and scale information in the area image 31 from the area image 31. Thereby, the coordinates of each point in the area image 31 can be obtained.

In some examples, the dispensing apparatus 1 may further include monitoring means for monitoring the loading means 10, the dispensing means 20, the positioning means 30 and the identifying means 40, the monitoring means being for monitoring the execution states of the respective means and performing a pause, stop or reset operation on the means in an abnormal state. In this case, the monitoring device can automatically process the device in the abnormal state, whereby the stability of the dispensing apparatus 1 can be improved.

As shown in fig. 6, in some examples, the dispensing apparatus 1 may further include a laser cutting device for removing the sensing electrodes 121 on the sensing electrode array plate 12. In this case, the sensing electrode 121 on the sensing array plate can be cut after the completion of the dispensing, whereby the individual sensing electrode 121 can be conveniently formed, and thus the individual glucose sensor 120 can be obtained.

As described above, glucose sensor 120 may also include reference electrode 122 and counter electrode 123 (see fig. 6).

In this embodiment, the reference electrode 122 may be at a known and fixed potential difference with interstitial fluid or blood. In this case, the potential difference between the sensing electrode 121 and the tissue fluid or blood can be measured by the potential difference formed between the reference electrode 122 and the sensing electrode 121, thereby accurately grasping the voltage generated by the sensing electrode 121.

In addition, in the present embodiment, the sensing electrode 121, the reference electrode 122, and the counter electrode 123 are disposed in a dispersed manner, but the embodiment of the present disclosure is not limited thereto, and may include a side-by-side (parallel) arrangement.

In addition, in the present embodiment, the glucose sensor 120 is not limited to the planar type, but may be a linear type sensor having stacked electrodes or layered electrodes, and a glucose sensor 120 having coplanar electrodes in which electrodes are disposed on the same plane.

In the present embodiment, as described above, the glucose sensor 120 may include a plurality of contacts (contacts). The number of contacts is equal to the number of electrodes of glucose sensor 120. And leads (wires) are connected between the contacts and the electrodes.

In the present embodiment, as shown in fig. 6, there are three electrodes of the glucose sensor 120. Accordingly, glucose sensor 120 includes three contacts (contacts), contact 124, contact 125, and contact 126, respectively.

In this embodiment, the contact 124, the contact 125, and the contact 126 may each have a disc shape. In other examples, contacts 124, 125, and 126 may also be rectangular, oval, or other irregular shapes.

While the disclosure has been described in detail in connection with the drawings and embodiments, it should be understood that the foregoing description is not intended to limit the disclosure in any way.
