[0038] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0040] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0041] It can be understood that the “connection” in the following embodiments should be understood as “electrical connection”, “communication connection”, etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0042] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0043] In the traditional business model, the drug circulation process is as follows: the doctor gives the order, then the nurse transcribes the order, and then sends it to the drug management system of the pharmacy department. The pharmacy department arranges the drugs according to the order, and then distributes them to the wards in batches and at different times. Finally, the nurse distributes the drugs to the patients according to the delivery order. In this model, the drug placement and distribution of the pharmacy department have a certain delay, which is prone to errors in the handover process with the nurses, and increases the workload of the pharmacy department when the drugs are expedited or returned. After applying the smart medicine cabinet management system, the business process changes from the traditional linear process to a star structure based on the smart medicine cabinet as the central process. In this model, the pharmacy department can grasp the drug inventory in the smart medicine cabinet in real time, replenish the inventory, recycle the returned drugs in time, etc.; after sending the order to the smart medicine cabinet management system, the nurse takes out the drugs for distribution according to the smart prompts of the smart medicine cabinet. This process eliminates some intermediate links in the traditional process, reduces the workload of the pharmacy department and nurses, and makes the drug supply more timely. At the same time, it clarifies the responsibilities and rights of the pharmacy department and ward nurses in the drug circulation process, and realizes the full traceability of the drug circulation process.

[0044] However, the purchase and maintenance costs of smart medicine cabinets are high, and there is also a problem of poor applicability in drug detection. The medicine bottle detection circuit provided in this application can effectively solve the above problems.

[0045] In one embodiment, Figure 1 As shown, a medicine bottle detection circuit is provided, comprising a light emitting device and a light receiving device arranged in a medicine bottle detection area; and also comprising a comparison circuit and a variable resistor circuit;

[0046] The light emitting device and the light receiving device cooperate to detect the missing state of the medicine bottle;

[0047] The first input end of the comparison circuit is connected to the light receiving device, the second input end is connected to the moving pin of the variable resistor circuit, and the output end is used to output the missing status signal of the medicine bottle; the first fixed pin of the variable resistor circuit is used to connect to an external power supply, and the second fixed pin is used for grounding.

[0048] Among them, the light emitting device can be any device in the art capable of emitting a light beam, such as an infrared emitting tube. The light receiving device can be any device or circuit in the art capable of generating a photoelectric effect based on a light beam, such as a circuit including a photodiode and a phototransistor. The medicine bottle detection area is an area for storing the detection device. The comparison circuit can be any circuit in the art with a voltage comparison function. The variable resistor circuit is used to provide a reference voltage to the comparison circuit.

[0049] Specifically, the light emitting device and the light receiving device are used together to detect the missing state of the medicine bottle. For example, a medicine bottle is arranged in the optical channel between the light emitting device and the light receiving device, and the medicine bottle is used to block the light beam to detect the presence of the medicine bottle.

[0050] The first fixed pin of the variable resistor circuit is used to connect an external power supply, the second fixed pin is used to ground, and the moving pin provides a divided voltage to the second input terminal of the comparison circuit, and the divided voltage is determined by the sliding position of the moving pin. The light receiving device is connected to the first input terminal of the comparison circuit to provide a detection voltage generated by the photoelectric effect. For general obstacles, the obstacles can completely block the light beam. For medicine bottles, due to the material of the medicine bottle, the light emitted by the light emitting device is refracted into the light receiving tube, resulting in the phenomenon that the light receiving device still receives part of the light beam even though the medicine bottle exists. The voltage value of the first input terminal of the comparison circuit is within a certain range. If the reference voltage is too small, the comparator may still output a signal indicating the absence of the medicine bottle in the presence of the medicine bottle. In this case, the reference voltage can be adjusted by the variable resistor circuit to detect the medicine bottle to prevent false detection. The voltage value of the first input terminal will be different according to the shape difference such as the size of the medicine bottle. The above variable resistor circuit can make the above medicine bottle detection circuit suitable for different types of medicine bottles.

[0051] The above medicine bottle detection circuit detects the medicine bottle through the light emitting device and the light receiving device, and adjusts the reference voltage output to the comparison circuit through the variable resistor circuit, thereby avoiding false detection. At the same time, the medicine bottle detection circuit can be adaptively adjusted to medicine bottles of different sizes through the variable resistor circuit, and has wide applicability.

[0052] In one embodiment, if Figure 2 As shown, the light emitting device includes a light emitting tube 111; one end of the light emitting tube is used to connect to an external power supply, and the other end is used to ground;

[0053] The light receiving device comprises a light receiving tube 113; one end of the light receiving tube 113 is used to connect to an external power supply VCC and to a first input end of a comparison circuit, and the other end is used to be grounded.

[0054] Specifically, since the light emitting tube is always powered on, it keeps emitting a light beam (such as infrared light, etc.), and when the light receiving tube receives the light beam emitted by the light emitting tube, its two ends can be connected. Therefore, when there is no medicine bottle between the light emitting tube and the light receiving tube, the voltage at the first input end of the comparison circuit is the power supply voltage of the external power supply. When the light receiving tube cannot receive the light beam emitted by the light emitting tube at all, the two ends of the light receiving tube are dielectric, and the first input end of the comparison circuit is grounded.

[0055] In one embodiment, if Figure 3 As shown, the light emitting device includes a light emitting tube 111; one end of the light emitting tube is used to connect to an external power supply, and the other end is used to ground;

[0056] The light receiving device comprises a light receiving tube 113; one end of the light receiving tube 113 is used to connect to an external power supply VCC and to a first input end of a comparison circuit, and the other end is used to be grounded.

[0057] Also includes a current limiting circuit;

[0058] One end of the light receiving tube is connected to an external power supply through a current limiting circuit.

[0059] Specifically, one end of the current limiting circuit is respectively connected to one end of the light receiving tube and the first input end of the comparison circuit, and the other end is connected to an external power supply for current limiting. In a specific embodiment, the current limiting circuit includes a current limiting resistor, one end of the current limiting circuit is respectively connected to one end of the light receiving tube and the first input end of the comparison circuit, and the other end is connected to an external power supply.

[0060] In one embodiment, if Figure 4 As shown, the light emitting device includes a light emitting tube 111; one end of the light emitting tube is used to connect to an external power supply, and the other end is used to ground;

[0061] The light receiving device comprises a light receiving tube 113; one end of the light receiving tube 113 is used to connect to an external power supply VCC and to a first input end of a comparison circuit, and the other end is used to be grounded.

[0062] Also includes a current limiting circuit;

[0063] Also includes capacitor C1;

[0064] One end of the capacitor C1 is connected to one end of the light receiving tube, and the other end of the capacitor C1 is connected to the other end of the light receiving tube.

[0065] Specifically, the capacitor C1 is used to stabilize the voltage across the light receiving tube. In a specific example, the voltage stabilizing capacitor may be a 0.1 μF capacitor.

[0066] In one embodiment, if Figure 5 As shown, it also includes a power indication circuit ( Figure 5 not shown);

[0067] The power indication circuit includes a light emitting diode D1, a resistor R1 and a capacitor C2; the anode of the light emitting diode D1 is used to connect to an external power supply, and the cathode is used to connect to one end of the resistor R1; the other end of the resistor R1 is used to be grounded; one end of the capacitor C2 is used to connect to an external power supply, and the other end is used to be grounded.

[0068] Specifically, the power indicator circuit is used to reflect the switching status of the power supply. When the power supply is on, the light emitting diode lights up. The resistor C1 is used for current limiting. The filter capacitor C2 is used for filtering.

[0069] In one embodiment, if Figure 6 As shown, it also includes a status indication circuit ( Figure 6 not shown);

[0070] The state indicating circuit comprises a light emitting diode D2 and a resistor R2; the anode of the light emitting diode D2 is used to connect to an external power supply, and the cathode is connected to one end of the resistor R2; the other end of the resistor R2 is connected to the output end of the comparison circuit.

[0071] Specifically, the status indication circuit is used to allow the user to judge the status of the medicine bottle from the indicator light (light emitting diode). The anode of the light emitting diode D2 is used to connect to an external power supply, and the cathode is connected to the output end of the comparator through a resistor R2. When the comparator outputs a low-level signal, the light emitting diode can light up. In this case, the first input end is the positive input end, and the second input end is the negative input end. When the light receiving tube cannot receive the light beam, the comparator outputs a low-level signal and the light emitting diode D2 lights up.

[0072] In one embodiment, a medicine bottle detection system is provided, such as Figure 7 As shown, it includes a processor and a plurality of missing detection modules; the missing detection module includes at least two medicine bottle detection circuits as any one of the above items;

[0073] Any medicine bottle detection circuit of the missing detection module is used to detect the missing state of the top of the medicine bottle, and the other medicine bottle detection circuit is used to detect the missing state of the bottom of the medicine bottle;

[0074] Each medicine bottle detection circuit is connected to the processor.

[0075] Among them, the missing detection module is used to detect the missing of the top and bottom of the medicine bottle. The type of processor is not limited, and can be equipped according to the actual application. It can be a general processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), an off-the-shelf programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc.

[0076] Specifically, the missing detection module includes at least two groups of medicine bottle detection circuits, any one of which is used to detect the top of the medicine bottle, and the other is used to detect the bottom of the medicine bottle. The detection result is characterized by a first state signal and a second state signal. It should be noted that the missing detection module also includes 3 groups of medicine bottle detection circuits, or 4 groups of medicine bottle detection circuits, as long as one group of medicine bottle detection circuits detects the missing state of the top of the medicine bottle, and another group of medicine bottle detection circuits detects the missing state of the bottom of the medicine bottle.

[0077] The processor can receive the first state signal and the second state signal by any means in the art. For example, it can be connected to each detection unit through a line to directly obtain the first state signal and the second state signal; for example, the first state signal and the second state signal can be forwarded to the processor through a wireless communication device. The missing state of the present application means that the corresponding part of the medicine bottle cannot be detected. The top missing state of the medicine bottle includes the top missing state and the top intact state. This is because the medicine will destroy its top to extract the liquid in the medicine bottle during use, and the medicine bottle will be taken out during use, resulting in the detection unit not being able to detect the top of the medicine bottle. The bottom missing state of the medicine bottle includes the bottom missing state and the bottom intact state. This is because the medicine will take out the medicine bottle during use, resulting in the detection unit not being able to detect the bottom of the medicine bottle. In summary, the state of the medicine bottle can be judged based on the bottom missing state and the top missing state of the medicine bottle. That is, when the top of the medicine bottle is missing or the bottom is missing, it can be determined that the medicine has been taken out; when the top of the medicine bottle is missing and the bottom is intact, it can be determined that the medicine is used (the top sealing cover of the medicine is discarded after use); when the top of the medicine bottle is intact or the bottom is intact, it can be determined that the medicine is brand new. In addition, the reference voltage output to the comparison circuit is adjusted by the variable resistor circuit to avoid false detection, so that the medicine bottle detection circuit can be adaptively adjusted for medicine bottles of different sizes, and has wide applicability.

[0078] In combination with the specific medicine bottle detection circuit, the fixed pin of its variable resistor circuit has been adjusted. If a brand new medicine is detected, for the medicine bottle detection circuit used to detect the top, the voltage of the first input terminal of the comparison circuit is greater than the voltage of the second input terminal. For the detection unit used to detect the bottom, the voltage of the first input terminal of the comparison circuit is greater than the voltage of the second input terminal. For example: when the first input terminal is the positive input terminal and the second input terminal is the negative input terminal, the processor receives two high-level signals.

[0079] If used medicines are detected, for the detection unit used to detect the top, the voltage of the first input terminal of the comparison circuit is less than the voltage of the second input terminal. For the detection unit used to detect the bottom, the voltage of the first input terminal of the comparison circuit is greater than the voltage of the second input terminal. Therefore, a corresponding level signal can be generated and given to the processor based on the actual voltage comparison of the first input terminal and the second input terminal. For example: when the first input terminal is a positive input terminal and the second input terminal is an inverting input terminal, the processor receives a high level signal and a low level signal.

[0080] If the medicine is taken out, for the detection unit for detecting the top, the voltage of the first input terminal of the comparison circuit is less than the voltage of the second input terminal. For the detection unit for detecting the bottom, the voltage of the first input terminal of the comparison circuit is less than the voltage of the second input terminal. Therefore, the corresponding level signal can be generated to the processor based on the actual voltage comparison of the first input terminal and the second input terminal. For example: when the first input terminal is the positive input terminal and the second input terminal is the negative input terminal, the processor receives two low-level signals.

[0081] The above-mentioned medicine bottle detection system detects the top missing state and the bottom missing state of the medicine bottle through two sets of medicine bottle detection circuits in the missing detection module, and transmits the detection results to the processor, so that the processor can obtain detection data on the medicine bottles in large quantities.

[0082] In one of the embodiments, a remote terminal is further included; the remote terminal is connected to the processor.

[0083] Specifically, the remote terminal obtains the detection data obtained by the processor, which makes it convenient for the back-end management personnel to understand the status of the medicine bottle in real time.

[0084] In one embodiment, further comprising a wireless communication device;

[0085] The remote terminal is connected to the processor via a wireless communication device.

[0086] Specifically, the processor transmits the detection data to the remote terminal via the wireless communication device.

[0087] In one embodiment, a medicine box is also provided, comprising a medicine box body, and a medicine bottle detection system as described in any one of the above items;

[0088] The medicine box body includes a plurality of accommodating cavities for accommodating medicine bottles; each accommodating cavity corresponds one-to-one to each missing detection module.

[0089] Specifically, the medicine box can be any medicine box for storing medicine bottles in the art. The medicine bottles in the accommodating cavity in the medicine box can be the same or different. In a specific example, the medicine box includes accommodating cavities of preset sizes for storing medicine bottles of various sizes. And each size of medicine bottle can use a corresponding variable resistor circuit to adjust a different reference voltage to avoid false detection. It should be noted that for the detection of medicine bottles, the size of the top and the bottom are also different, so the different medicine bottle detection circuits in each group of missing detection modules, and their variable resistor circuits also need to adjust different reference voltages.

[0090] In the description of this specification, the description with reference to the terms "some embodiments", "other embodiments", "ideal embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example.

[0091] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
