Description

Technical Field

[0001] The present application relates to the technical field of storage of liquid injections for intravenous medication, and in particular to an intelligent storage device for liquid injection bottles and a method for monitoring the status of medicines. Background Art

[0002] The storage of injectable drugs requires strict environmental control and precise quantity management. Due to the special working mode of the intravenous preparation center, a large number of syringe bottles need to be unpacked for short-term storage. However, the entire cabinet material of the current medicine storage cabinet is relatively hard, and the internal space is not reasonably set up. Glass ampoules will break after a slight collision. If not discovered in time, it is easy to cause occupational injuries such as sharp injuries. The leaked liquid medicine is also easy to contaminate other drugs, and it is impossible to monitor the breakage of drugs. If the generated drug stains are not cleaned in time, the iron storage cabinet will rust, which is not conducive to drug storage. At the same time, due to the large number of drugs used every day, the existing medicine storage cabinets have a single function and cannot accurately monitor the number of drugs, which makes it difficult to count the number of drugs. This may also lead to insufficient replenishment of the number of drugs in the storage cabinet, affecting work efficiency. In addition, the current medicine storage cabinets have a single function and cannot effectively manage drug batch numbers and expiration information, which can easily lead to drug waste or failure due to improper storage.

[0031] Below, in conjunction with the accompanying drawings, a liquid injection bottle intelligent storage device and a drug status monitoring method provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0032] Example 1:

[0033] The first embodiment of the present application provides a liquid injection bottle intelligent storage device, referring to Figure 1 The intelligent storage device for liquid injection bottles includes a micro pressure sensor, a control mechanism, a display mechanism, a water immersion sensor, a drug information management system, a drug intelligent storage cabinet, an alarm device and a buffer device; the drug information management system includes an input module and a storage module, the buffer device includes a mesh buffer pad layer and a cross-shaped buffer partition, the mesh buffer pad layer is arranged at the bottom of the drug intelligent storage cabinet, a slot is arranged in the mesh buffer pad layer, and the cross-shaped buffer partition is embedded in the slot, the micro pressure sensor and the water immersion sensor are both arranged at the bottom of the drug intelligent storage cabinet, the micro pressure sensor and the water immersion sensor are respectively connected to the control mechanism, the control mechanism is respectively connected to the display mechanism and the alarm device, the input module is connected to the storage module, and the storage module is connected to the display mechanism; the input module is used to enter the batch number information and expiration date information of the liquid injection bottles stored in the drug intelligent storage cabinet, and the storage module is used to store the batch number information and expiration date information of the liquid injection bottles The batch number information and expiration date information of the bottles are stored, and the display mechanism is used to display the batch number information and expiration date information of the liquid injection bottles; the micro pressure sensor is used to monitor the pressure at the bottom of the smart medicine storage cabinet in real time to generate a pressure detection signal, and transmit the pressure detection signal to the control mechanism, the control mechanism is used to confirm the current number value of the liquid injection bottles stored in the smart medicine storage cabinet according to the pressure detection signal and transmit the current number value of the liquid injection bottles to the display mechanism, and the display mechanism is also used to display the current number value of the liquid injection bottles; the water immersion sensor is used to detect liquid leakage in the smart medicine storage cabinet in real time, and generate a liquid leakage signal when liquid flow is detected, and transmit the liquid leakage signal to the display mechanism through the control mechanism for display, and the water immersion sensor is also used to transmit the liquid leakage signal to the alarm device through the control mechanism to trigger the alarm signal through the alarm device.

[0034] In some embodiments, the control mechanism is a PLC controller, and the liquid medicines stored in the same smart medicine storage cabinet are of the same type. The micro pressure sensor can detect the total weight of all liquid injection bottles placed in the smart medicine storage cabinet in real time and generate a pressure detection signal. The control mechanism processes and analyzes the pressure detection signal transmitted by the micro pressure sensor. The control mechanism calculates the number of liquid injection bottles stored in the smart medicine storage cabinet based on the total weight and unit mass of the same type of medicines, and displays the number of liquid injection bottles on the display mechanism. There is no need to manually count and modify the quantity, which reduces errors and is also conducive to inventory. This precise medicine quantity monitoring function can ensure the continuity of medicine supply and avoid medical inconvenience and waste of resources caused by out-of-stock or backlogs.

[0035] In some embodiments, the micro pressure sensor is a ZCL504 micro weighing sensor with a working pressure of 0-30kg. It is connected to a PLC controller, and the same type of medicine is placed in the smart medicine storage cabinet, and its total weight and single weight are measured, and then transmitted to the PLC controller through the circuit. The PLC controller uses the total weight divided by the unit mass of the medicine to calculate the number of the same type of medicine in the smart cabinet, and then transmits it to the display mechanism. The display mechanism can update the number of medicines in the storage cabinet in real time.

[0036] It should be noted that the batch number and expiration date information of the drug are entered through the input module in the drug information management system, the storage module stores this information, and the display mechanism is used to display the drug information. The drug name, batch number, expiration date, and quantity can all be displayed through the display mechanism, so that the staff can reasonably arrange the order of drug use, reduce the waste of expiring drugs, and improve the utilization rate of medical resources.

[0037] In some embodiments, the mesh cushion layer inside the smart medicine storage cabinet is surrounded by 1 cm thick foam rubber, and the cross-shaped buffer partition is made of EVA material, which divides the cabinet into four independent spaces. This buffer device can significantly reduce the damage caused by the disorderly placement of scattered medicines inside the medicine box, reduce the waste of medicine resources and occupational hazards, and the buffer partition is cross-shaped and embedded in the slot to divide the cabinet into storage compartments with 4 independent spaces, reducing the movement of individual medicines and reducing collisions.

[0038] Through this setting, this application improves the existing medicine bottle storage cabinet to make it more intelligent, thereby improving the efficiency of the intravenous preparation center staff, providing more accurate services to the clinic, and ensuring the safety of patients' medication.

[0039] Reference Figure 1It can be understood that the drug information management system also includes an expiring drug judgment module, which is respectively connected to the display mechanism and the storage module. The storage module is used to send the expiration information corresponding to the liquid injection bottle to the expiring drug judgment module. The expiring drug judgment module is also used to judge in real time whether the expiration date of the liquid injection bottle is near the expiration date based on the expiration date information, generate a warning signal when the expiration date of the liquid injection bottle is near the expiration date, and transmit the warning signal to the display mechanism for display on the display mechanism.

[0040] It should be noted that the near expiration date is set according to the expiration date of the liquid injection bottles stored in the smart medicine storage cabinet, and is not specifically limited in this embodiment of the present application.

[0041] It should be noted that the near-expiry drug judgment module of the drug information management system regularly checks the expiration date of drugs. When the drugs are close to their expiration date, the display mechanism displays a warning message to remind staff to give priority to the use of near-expiry drugs.

[0042] It should be noted that during normal use, the water immersion sensor is in standby monitoring status. When the drug is damaged and liquid leaks and contacts the water immersion sensor, the water immersion sensor will send the detected signal to the control mechanism. The control mechanism triggers the alarm device to issue an alarm message and records the damage of the drug in the drug information management system. The staff will clean up the leaked liquid and damaged drugs in time according to the alarm information to prevent contamination of other drugs, and analyze the relevant information of the damaged drugs to check whether there are batch problems or other potential risks.

[0043] In some embodiments, the display mechanism is a 7-inch KD-01X170E series embedded capacitive touch display. Through the information management system, the settings of the input module and storage module are completed to determine the entry format, storage method and expiring drug judgment criteria of the relevant display information.

[0044] In some embodiments, the sensitivity of the water immersion sensor is calibrated and initialized. The water immersion sensor is a WLS-1S water immersion sensor, which uses the principle of liquid conductivity for monitoring. When the medicine in the smart medicine storage cabinet is damaged, the liquid flows, thereby causing the two-pole probe of the water immersion sensor to be turned on. The water immersion sensor outputs a signal, which is transmitted to the PLC controller through the circuit. The PLC control mechanism feeds back to the display mechanism and the alarm device, and the alarm device triggers an alarm reminder.

[0045] It should be noted that by setting up an expiring drug judgment module, drug damage and leakage can be discovered in a timely manner, drug contamination and storage environment deterioration can be avoided, and the safety of the entire drug storage can be ensured.

[0046] It can be understood that the control mechanism is provided with a data processing module and a drug weight-quantity conversion module. The data processing module is used to confirm the total weight value of the liquid injection bottles stored in the drug intelligent storage cabinet based on the pressure detection signal, and the drug weight-quantity conversion module is used to convert and calculate the total weight value and the unit mass of the liquid injection bottles to obtain the current quantity value of the liquid injection bottles stored in the drug intelligent storage cabinet.

[0047] It should be noted that by setting up a data processing module and a drug weight-quantity conversion module in the control mechanism, accurate drug quantity monitoring in the smart drug storage cabinet can be achieved. The accurate drug quantity monitoring function can ensure the continuity of drug supply and avoid medical inconvenience and waste of resources caused by shortages or backlogs.

[0048] It is understandable that the shell of the smart medicine storage cabinet is made of polymer insulating lightweight material.

[0049] It should be noted that the shell of the medicine smart storage cabinet is made of a polymer insulating lightweight material to prevent the liquid injection bottles in the medicine bottle smart storage cabinet from colliding with the shell, thereby preventing the bottles from breaking and leaking the liquid injection.

[0050] In some embodiments, the water immersion sensor, the micro pressure sensor, the control mechanism, and the display mechanism are all connected to the wiring terminals, and the wiring terminals are connected to the DC output module outside the cabinet of the intelligent medicine storage cabinet. The wiring terminals have 4 negative terminals, 4 positive terminals and a DC input terminal. The DC output module includes a 24V DC output, a ground wire, a live wire terminal and a neutral wire terminal. The 24V DC output of the DC output module is connected to the DC input terminal of the wiring terminal, and the ground wire, the live wire terminal and the neutral wire terminal are connected to the power supply. The power supply input terminals of the water immersion sensor, the micro pressure sensor, the control mechanism and the display mechanism are respectively connected to the 4 positive terminals of the wiring terminal, and the power supply output terminals of the water immersion sensor, the micro pressure sensor, the control mechanism and the display mechanism are respectively connected to the 4 negative terminals of the wiring terminal. The four CAN lines of the control mechanism are respectively connected to the water immersion sensor and the micro pressure sensor, and the serial port line of the control mechanism is connected to the display mechanism.

[0052] In some embodiments, the display mechanism is mounted on an outer wall of a cabinet formed by a combination of multiple layers of medicine storage shelves.

[0053] In the present application, the batch number information and expiration date information of the liquid injection bottles stored in the smart medicine storage cabinet are input through the input module, the batch number information and expiration date information of the liquid injection bottles are stored through the storage module, and the batch number information and expiration date information of the liquid injection bottles are displayed through the display mechanism; the pressure at the bottom of the smart medicine storage cabinet is monitored in real time by a micro pressure sensor to generate a pressure detection signal, and the pressure detection signal is transmitted to the control mechanism, so that the control mechanism confirms the current number value of the liquid injection bottles stored in the smart medicine storage cabinet according to the pressure detection signal; the current number value of the liquid injection bottles is transmitted to the display mechanism through the control mechanism and displayed on the display mechanism; the liquid leakage in the smart medicine storage cabinet is detected in real time by the water immersion sensor, and a liquid leakage signal is generated when liquid flow is detected, the liquid leakage signal is transmitted to the display mechanism through the control mechanism and displayed on the display mechanism, the liquid leakage signal is transmitted to the alarm device through the control mechanism, and the alarm signal is triggered by the alarm device. Through this method, the present application realizes accurate monitoring and effective management of drug quantity, expiration date and damage through the collaborative work of multiple sensors and intelligent management systems, thereby ensuring the storage quality and safety of injectable drugs.

[0054] Example 2:

[0055] Reference Figure 2 , Figure 2 A drug status monitoring method provided by an embodiment of the second aspect of the present application is shown. The method is also applied to a liquid injection bottle intelligent storage device and is executed by the liquid injection bottle intelligent storage device. The liquid injection bottle intelligent storage device includes a micro pressure sensor, a control mechanism, a display mechanism, a water immersion sensor, a drug information management system, a drug intelligent storage cabinet, an alarm device and a buffer device. The drug information management system includes an input module and a storage module. The buffer device includes a mesh buffer pad layer and a cross-shaped buffer partition. The mesh buffer pad layer is provided at the bottom of the drug intelligent storage cabinet. A slot is provided in the mesh buffer pad layer. The cross-shaped buffer partition is embedded in the slot. The micro pressure sensor and the water immersion sensor are both provided at the bottom of the drug intelligent storage cabinet. The micro pressure sensor and the water immersion sensor are respectively connected to the control mechanism. The control mechanism is respectively connected to the display mechanism and the alarm device. The input module is connected to the storage module. The storage module is connected to the display mechanism. The drug status monitoring method includes the following steps:

[0056] Step S110, input the batch number information and expiration date information of the liquid injection bottle stored in the smart medicine storage cabinet through the input module, store the batch number information and expiration date information of the liquid injection bottle through the storage module, and display the batch number information and expiration date information of the liquid injection bottle through the display mechanism.

[0057] In this step, the batch number and expiration date information of the drug are entered through the input module in the drug information management system, the storage module stores this information, and the display mechanism is used to display the drug information. The drug name, batch number, expiration date, and quantity can all be displayed through the display mechanism, so that the staff can reasonably arrange the order of drug use, reduce the waste of expiring drugs, and improve the utilization rate of medical resources.

[0058] In step S120, the pressure at the bottom of the smart medicine storage cabinet is monitored in real time by a micro pressure sensor to generate a pressure detection signal, and the pressure detection signal is transmitted to the control mechanism so that the control mechanism confirms the current number of liquid injection bottles stored in the smart medicine storage cabinet based on the pressure detection signal.

[0059] Step S130: The current quantity value of the liquid injection bottles is transmitted to the display mechanism through the control mechanism and displayed on the display mechanism.

[0060] In some embodiments, the control mechanism is a PLC controller, and the liquid medicines stored in the same smart medicine storage cabinet are of the same type. The micro pressure sensor can detect the total weight of all liquid injection bottles placed in the smart medicine storage cabinet in real time and generate a pressure detection signal. The control mechanism processes and analyzes the pressure detection signal transmitted by the micro pressure sensor. The control mechanism calculates the number of liquid injection bottles stored in the smart medicine storage cabinet based on the total weight and unit mass of the same type of medicines, and displays the number of liquid injection bottles on the display mechanism. There is no need to manually count and modify the quantity, which reduces errors and is also conducive to inventory. This precise medicine quantity monitoring function can ensure the continuity of medicine supply and avoid medical inconvenience and waste of resources caused by out-of-stock or backlogs.

[0061] In some embodiments, the micro pressure sensor is a ZCL504 micro weighing sensor with a working pressure of 0-30kg. It is connected to a PLC controller, and the same type of medicine is placed in the smart medicine storage cabinet, and its total weight and single weight are measured, and then transmitted to the PLC controller through the circuit. The PLC controller uses the total weight divided by the unit mass of the medicine to calculate the number of the same type of medicine in the smart cabinet, and then transmits it to the display mechanism. The display mechanism can update the number of medicines in the storage cabinet in real time.

[0062] In step S140, the liquid leakage in the smart medicine storage cabinet is detected in real time through the water immersion sensor, and a liquid leakage signal is generated when the liquid flow is detected. The liquid leakage signal is transmitted to the display mechanism through the control mechanism and displayed on the display mechanism. The liquid leakage signal is transmitted to the alarm device through the control mechanism and the alarm signal is triggered through the alarm device.

[0063] In some embodiments, the sensitivity of the water immersion sensor is calibrated and initialized. The water immersion sensor is a WLS-1S water immersion sensor, which uses the principle of liquid conductivity for monitoring. When the medicine in the smart medicine storage cabinet is damaged, the liquid flows, thereby causing the two-pole probe of the water immersion sensor to be turned on. The water immersion sensor outputs a signal, which is transmitted to the PLC controller through the circuit. The PLC control mechanism feeds back to the display mechanism and the alarm device, and the alarm device triggers an alarm reminder.

[0064] In some embodiments, the display mechanism is a 7-inch KD-01X170E series embedded capacitive touch display. Through the information management system, the settings of the input module and storage module are completed to determine the entry format, storage method and expiring drug judgment criteria of the relevant display information.

[0065] In one possible implementation, the shell of the smart medicine storage cabinet is made of a polymer insulating lightweight material.

[0066] It should be noted that the shell of the medicine smart storage cabinet is made of a polymer insulating lightweight material to prevent the liquid injection bottles in the medicine bottle smart storage cabinet from colliding with the shell, thereby preventing the bottles from breaking and leaking the liquid injection.

[0067] In one possible implementation, the intelligent storage device for liquid injection bottles also includes multi-layer medicine storage shelves, each layer of which is equipped with multiple intelligent medicine storage cabinets arranged side by side, and the number of micro pressure sensors, water immersion sensors and buffer devices corresponds to the number of intelligent medicine storage cabinets.

[0068] In some embodiments, the display mechanism is mounted on an outer wall of a cabinet formed by a combination of multiple layers of medicine storage shelves.

[0069] Reference Figure 3 It is understood that the drug information management system further includes an expiring drug judgment module, which is connected to the display mechanism and the storage module respectively. After the batch number information and expiration date information of the liquid injection bottle are stored in the storage module in step S110, the following steps are included but are not limited to:

[0070] In step S111, the expiration date information corresponding to the liquid injection bottle is sent to the expiring drug judgment module through the storage module, so that the expiring drug judgment module can judge in real time whether the expiration date of the liquid injection bottle is near the expiration date based on the expiration date information, generate a warning signal when the expiration date of the liquid injection bottle is near the expiration date, and transmit the warning signal to the display mechanism for display on the display mechanism.

[0071] In this step, the near-expiry drug judgment module of the drug information management system regularly checks the expiration date of the drug. When the drug is close to the expiration date, the display mechanism displays a warning message to remind staff to give priority to the near-expiry drug.

[0072] It should be noted that by setting up an expiring drug judgment module, drug damage and leakage can be discovered in a timely manner, drug contamination and storage environment deterioration can be avoided, and the safety of the entire drug storage can be ensured.

[0073] It should be noted that during normal use, the water immersion sensor is in standby monitoring status. When the drug is damaged and liquid leaks and contacts the water immersion sensor, the water immersion sensor will send the detected signal to the control mechanism. The control mechanism triggers the alarm device to issue an alarm message and records the damage of the drug in the drug information management system. The staff will clean up the leaked liquid and damaged drugs in time according to the alarm information to prevent contamination of other drugs, and analyze the relevant information of the damaged drugs to check whether there are batch problems or other potential risks.

[0074] Reference Figure 4 It is understood that the drug status monitoring method also includes but is not limited to the following steps:

[0075] Step S121, obtain the unit mass of the liquid injection bottles stored in the smart medicine storage cabinet, and transmit the unit mass to the control mechanism so that the control mechanism confirms the current number of liquid injection bottles stored in the smart medicine storage cabinet based on the unit mass and pressure detection signal.

[0076] Exemplarily, the micro pressure sensor is a ZCL504 micro weighing sensor with a working pressure of 0-30kg. It is connected to a PLC controller. The same kind of medicine is placed in the smart medicine storage cabinet, and its total weight and single weight are measured. Then, the information is transmitted to the PLC controller through the circuit. The PLC controller divides the total weight by the unit mass of the medicine to calculate the quantity of the same kind of medicine in the smart cabinet, and then transmits it to the display mechanism. The display mechanism can update the quantity of medicines in the storage cabinet in real time.

[0077] Reference Figure 5 It is understood that the control mechanism is provided with a data processing module and a medicine weight-quantity conversion module. The data processing module confirms the total weight value of the liquid injection bottles stored in the medicine smart storage cabinet based on the pressure detection signal. The control mechanism in step S120 confirms the current quantity value of the liquid injection bottles stored in the medicine smart storage cabinet based on the unit mass and the pressure detection signal, including but not limited to the following steps:

[0078] It should be noted that by setting up a data processing module and a drug weight-quantity conversion module in the control mechanism, accurate drug quantity monitoring in the smart drug storage cabinet can be achieved. The accurate drug quantity monitoring function can ensure the continuity of drug supply and avoid medical inconvenience and waste of resources caused by shortages or backlogs.

[0079] Step S122: The total weight value and the unit mass are converted and calculated by the medicine weight-quantity conversion module to obtain the current quantity value of the liquid injection bottles stored in the medicine intelligent storage cabinet.

[0080] The storage of injectable drugs requires strict environmental control and precise quantity management. Due to the special working mode of the intravenous preparation center, a large number of liquid injection bottles need to be unpacked and stored for a short period of time. However, the current medicine storage cabinet is made of a relatively hard material and the internal space is not reasonably set up. Glass ampoules will break after a slight collision. If not discovered in time, it is easy to cause occupational injuries such as sharp injuries. The leaked liquid medicine is also easy to contaminate other drugs, making it impossible to monitor drug breakage. If the generated drug stains are not cleaned in time, the iron storage cabinet will rust, which is not conducive to drug storage. At the same time, due to the large number of drugs used every day, the existing medicine storage cabinets have a single function and cannot accurately monitor the number of drugs, which makes it difficult to count the number of drugs. This may also lead to insufficient replenishment of the number of drugs in the storage cabinet, affecting work efficiency. In addition, the current medicine storage cabinets have a single function and cannot effectively manage drug batch numbers and expiration information, which can easily lead to drug waste or failure due to improper storage.

[0081] Therefore, the liquid injection bottle intelligent storage device provided in the embodiment of the present application inputs the batch number information and expiration date information of the liquid injection bottle stored in the intelligent medicine storage cabinet through the input module, stores the batch number information and expiration date information of the liquid injection bottle through the storage module, and displays the batch number information and expiration date information of the liquid injection bottle through the display mechanism; monitors the pressure at the bottom of the intelligent medicine storage cabinet in real time through a micro pressure sensor to generate a pressure detection signal, and transmits the pressure detection signal to the control mechanism, so that the control mechanism confirms the current number value of liquid injection bottles stored in the intelligent medicine storage cabinet according to the pressure detection signal; transmits the current number value of liquid injection bottles to the display mechanism through the control mechanism and displays it on the display mechanism; detects liquid leakage in the intelligent medicine storage cabinet in real time through a water immersion sensor, and generates a liquid leakage signal when liquid flow is detected, transmits the liquid leakage signal to the display mechanism through the control mechanism and displays it on the display mechanism, transmits the liquid leakage signal to the alarm device through the control mechanism and triggers the alarm signal through the alarm device. Through this method, the present application realizes accurate monitoring and effective management of drug quantity, expiration date and damage through the collaborative work of multiple sensors and intelligent management systems, thereby ensuring the storage quality and safety of injectable drugs.
