In the utility model, the medical medicine trolley is a movable medicine storage cabinet or a storage device and is generally used for storing common medicines and rescue medicines. The medical medicine cart is movably arranged at a place where medicines are needed to be used, so that the medicines are convenient to clinically use.
In the illustrated embodiment, the medical drug substance is comprised essentially of the following structure: a console 12, drawers, article shelves, storage cabinets or boxes 21, universal wheels 11, etc. However, the medical drug of the present utility model is not limited to the configuration shown in the illustrated embodiment.
The medicines are generally required to be stored separately as needed. For example, the mental drugs and partial anesthetic drugs commonly used by anesthesiologists need to be taken from a warehouse managed by a special person according to the regulations of the national "rules for managing anesthetic drugs and mental drugs", the taker is responsible for managing and preserving during the use, and the partial drugs have more strict storage conditions, such as Aikesong (2-8 ℃ in dark place) and propofol (2-25 ℃), and the mental drugs should be strictly managed.
For some specific medical drug vehicles, for example, for the special anesthetic drug vehicle in an operating room, because of the need of temporarily storing anesthetic drugs and rescue drugs, the prior art solution is to install a password safe box in the drug vehicle, so that the security level is improved. The safety of the narcotics is improved to a certain extent by the built-in password safe box, but the password input and replacement operations are complex, and the proper preservation of the narcotics often flows in a form due to the default public password.
The medical medicine cart can properly store narcotics and perform classified authorization management on the medicines. Moreover, the medical drug cart can automatically collect the drug taking trace and automatically and synchronously use the record. In addition, the medical medicine trolley can automatically and electronically manage the stored medicines, and realize automatic early warning of low storage quantity.
Specifically, as shown in the figure, the medical drug cart of the present utility model comprises: a vehicle body 1, and a storage unit and a recording unit 5 provided on the vehicle body 1,
a weighing unit 6 is arranged in the storage unit, the weighing unit 6 weighs the medicines placed in the storage unit,
the recording unit 5 records the weighing result of the weighing unit 6,
wherein the storage units comprise a conventional storage unit 2, a refrigerated storage unit 3 and an encrypted storage unit 4.
In this patent, the storage unit refers to a storage space that can be opened and closed independently. That is, the medical drug cart of the present utility model may include one or more conventional storage units 2, one or more refrigerated storage units 3 (two refrigerated storage units located below the console are shown in fig. 1); and/or one or more encrypted storage units 4 (one encrypted storage unit 4 is shown in fig. 1). It will be appreciated that the medical drug cart of the present utility model may not include conventional storage units, but may include only the refrigerated storage unit 3 and the encrypted storage unit 4. For example, the storage units are all configured as encrypted storage units, wherein part of the encrypted storage units simultaneously have a refrigerating storage function.
The memory cells may be of any suitable construction, size and material. As long as a storage space can be provided. Structurally, the storage unit may be a storage cabinet, drawer, storage rack, or the like. Dividers such as partitions may be further provided within the cabinet or drawer to create a smaller compartment. Further, a storage unit may include multiple storage cabinets or multiple drawers, and may also include one or more storage cabinets, as well as one or more drawers. Advantageously, the storage unit has opening and closing means for doors, shutters or similar functions. For example, the outer panel of the drawer may be considered the opening and closing structure.
The conventional storage unit 2 is mainly used for storing common non-controlled medicines or rescue medicines and other non-medicinal products. The cold storage unit 3 is mainly used for storing medicines or other articles needing cold storage. The encryption storage unit 4 is used for storing controlled medicines. For example, the encryption storage unit 4 is used for temporarily storing narcotics. That is, the conventional storage unit is a storage unit having no refrigeration function and no encryption function. Even a conventional storage unit or a part of its storage area may not be provided with a lock and a weighing unit.
Advantageously, the refrigerating storage unit 3 is provided with a temperature-adjustable refrigerating system and a high-low temperature alarm function. And alarming when the temperature is too high or too low.
Preferably, each storage unit has a plurality of spaced-apart storage areas, at least part of which is provided with a weighing unit 6 at the bottom. A weighing unit may be provided at the bottom of each storage area, or only at the bottom of a portion of the storage areas. All weighing units are in communication connection with the recording unit. Can be directly connected in communication or indirectly connected in communication. For example, in one embodiment, all weighing units are connected by encoders to a control unit, which is connected to the recording unit.
In another embodiment, all weighing cells (typically a plurality of weighing cells) are each connected to the CAN bus, said registration cells being also connected to the CAN bus. Only one weighing unit CAN transmit data to the recording unit through the CAN bus at a time. Thereby simplifying the circuit structure and simplifying the layout of the circuit. And meanwhile, corresponding control software can be simpler.
It is understood that each memory cell may have one or more memory regions. Advantageously, each storage area stores only one type of medicament, so that the weight of the medicament stored in each storage area can be more easily automatically recorded and managed, and the amount of the stored medicament is determined based on the weight. Thus, the taking condition of the medicine or the drug is finally determined.
In the case where a plurality of medicines are stored in one storage area, if the medicines have different single weights, the weights of two or more medicines stored cannot be directly derived though the weights currently measured. However, the weight (change in weight) for each medicine taking can be calculated from each change in weight, and thus the medicine taking condition for a certain period of time can be further determined. However, if two medicaments have the same or substantially the same weight, other means are needed to assist in determining the medication usage, for example by adding bar code identification.
It should be noted that only a portion of the storage units may be weight monitored. That is, the weighing cells are provided only in part of the storage cells.
The weighing unit may employ any electronic weighing device as long as the electronic weighing device is capable of weighing and outputs a weighing result (weighing information) in an electronic form. Advantageously, the electronic weighing device outputs a digitized weighing result. For example, the weighing unit is an embedded electronic balance. The electronic balance can sensitively sense the weight of the liquid medicine or the medicine.
It will be appreciated that the medical drug cart will be provided with a plurality of weighing units to monitor the weight of a plurality of storage areas. If each storage area corresponds to one medicine, the weight and taking condition of various medicines can be monitored. Advantageously, the plurality of weighing cells are identical weighing cells.
Because the CAN bus has the characteristics of small line number (only two lines of CAN_H and CAN_L), no central processing unit (main control unit) is needed, the communication mode is flexible, and a plurality of electronic units CAN be connected. CAN is a shorthand for Controller AreaNetwork, chinese name controller area network. Specifically, the plurality of weighing units are connected with the recording unit 5 using a CAN bus to transmit weighing information of each weighing unit 6 to the recording unit 5. That is, the plurality of weighing units 6 and the recording unit 5 are both connected to the CAN bus.
Because the weighing cells are identical in physical structure, the CAN bus may have difficulty effectively identifying a particular weighing cell when communicating. For this purpose, in the present utility model, a plurality of weighing cells are serially connected in sequence using a hard wire other than the CAN bus. More specifically, each weighing cell 6 has a bus interface and two control interfaces (control interface a and control interface B). The bus interface of each weighing cell 6 is connected to a CAN bus. The weighing units 6 are sequentially connected in series through the control interfaces, wherein the control interface B of the former weighing unit is connected with the control interface A of the latter weighing unit, the control interface A of the first weighing unit is grounded, and the control interface B of the last weighing unit is suspended.
In this way, a plurality of weighing cells are physically distinguished in a simple manner. Thus, when addressing, it is possible to accurately correspond to a specific weighing cell; or can assign addresses to all weighing cells in an orderly fashion.
For example, the weighing cells can be assigned addresses in the following way.
Step S1: setting the control interfaces B of all weighing units high, detecting the voltage of the control interface A of each weighing unit, if the voltage of the control interface A is high, the weighing unit is always in the process of detecting the voltage of the control interface A, if the voltage of the control interface A is low (ground), the weighing unit detects whether a CAN message with an address value x is received or not, if not, the step S2 is switched to, if so, the step S3 is switched to, wherein x is an integer (binary number) which is greater than or equal to zero;
step S2: the weighing unit sets the own address value as x=0, and goes to step S4;
step S3: the weighing unit sets the own address value as x=x+1, and goes to step S4;
step S4: judging whether x is smaller than n or not, if not, ending address allocation, sending an address allocation ending command by the weighing unit through the CAN bus, informing other weighing units to enter a normal mode, and simultaneously entering the normal mode; if less than n, go to step S5, where n = the total number of weighing cells minus 1;
step S5: the weighing unit sets the control interface B thereof to be low, sends the address value of the weighing unit through the CAN bus, and then the weighing unit which completes the address allocation of the weighing unit checks whether the command of ending the address allocation is received or not, and if the command of ending the address allocation is not received, the weighing unit always detects the command; if so, entering a normal mode. The normal mode is a mode in which instructions are waited or access is made.
Each embedded electronic balance corresponds to a storage area, or weighing area. The tray of the embedded electronic balance is the bottom of the storage area. The stored medicine is directly placed on the tray of the embedded electronic balance. Advantageously, a corresponding recess may be provided in the tray, corresponding to the shape of the recess, for storing the medicine to be stored, for placing and protecting the corresponding medicine, preventing the medicine from being displaced or collided when the vehicle moves. For example, the recess is arranged to correspond to an ampoule, a penicillin bottle or a syringe. Further, for example, 10/20 ampoule bottles and penicillin bottles can be used as a weighing platform, and a weighing unit is arranged. For example, in fig. 4, the upper 5 storage areas, the middle 3 storage areas, and the lower 5 storage areas are shown. While in fig. 5, 2 storage areas on the right side are shown, and 3 storage areas on the right side.
The recording unit 5 may employ any suitable recording apparatus or device. For example, recording is performed using a flash memory, a hard disk, or the like. Advantageously, the recording unit 5 records the access information of the drug in real time and synchronizes said access information to a background system (e.g. an anesthesia information system, or a drug management system of the whole hospital, etc.). In a specific embodiment, the recording unit 5 records the usage of the drug in each syringe segment and the time point in real time. Advantageously, each piece of information recorded by the recording unit includes a weighing unit number (indicating what medicament is taken), a weighing result (indicating the amount taken) and a time (indicating the time taken). Thus, the medicine taking condition is accurately recorded. The weighing cell number can be understood as the ID number of the weighing cell, or the weighing cell address value below. The time may be the time of weighing or the time of recording. Advantageously, the time is the time at which the recording is made.
Preferably, each memory cell has an opening detection means 7. When the storage unit is opened, the opening detection device 7 triggers the corresponding weighing unit 6 to weigh, and sends the weighing result to the recording unit 5. It will be appreciated that the weighing unit may also always weigh in real time. However, the linkage mode of triggering weighing during opening is beneficial to saving electricity, prolonging the service life of the weighing unit and reducing the cost of the weighing unit.
The opening detection means 7 may be any suitable device or detection means, as long as it is capable of detecting the opening of the memory cell and emitting a detection signal. In one embodiment, the opening detection means 7 is a micro switch. When the storage unit is opened, namely when the opening and closing structural members of the storage unit deviate from the closing positions, the micro switch is in the closing position, so that a power supply circuit of the weighing unit is connected, the weighing unit works, and the weighing result is transmitted to the recording unit. When the storage unit is closed, the micro switch is in an off position to disconnect the power supply of the weighing unit, so that the weighing unit stops working. It will be appreciated that the opening detection means 7 may also be a photoelectric switch or the like.
The encryption storage unit 4 may be locked or locked in any way. For example, a coded lock, a special key, or the like may be employed. Advantageously, the locking can be performed by fingerprint, gesture encryption and voice recognition, the setting and modification are simple and convenient, and the modification process is automatically recorded and can be combined with the token.
Preferably, the encryption storage unit 4 is locked by a fingerprint lock 41. Therefore, when the input fingerprint is matched with the prestored fingerprint, the fingerprint lock can be opened, the encryption storage unit is opened, and medicines needing strict management are taken or put in. Such as narcotics and the like. Further, since the fingerprint lock is used for locking, the record of taking or putting in is corresponding to a specific operator, so that traceability is further improved, and possibility of mistaking and mistaking is reduced. It will be appreciated that for a fingerprint lock, a plurality of fingerprint passwords may be provided. That is, it is possible to set that a plurality of persons have authority to be able to turn on the encryption storage unit. This is also within the scope of the present utility model.
Preferably, the fingerprint lock 41 is linked with the opening detection device 7 corresponding to the encryption storage unit 4, and in the case that the fingerprint lock 41 is unlocked, the opening detection device 7 triggers the corresponding weighing unit 6 to weigh, and sends the weighing result to the recording unit 5.
Preferably, the medical drug cart further comprises a timer 8, the timer 8 triggers the weighing unit 6 to weigh at set time intervals, and sends the weighing result to the recording unit 5. The set time interval may be referred to as a first weighing time interval or a conventional weighing time interval, for example 1 hour, or 10 minutes. It will be appreciated that the weighing cell may also be operated and sensing weight in real time at all times. However, this approach affects the life of the weighing cell or will increase the cost of the weighing cell. Particularly because some embodiments of the present utility model will use multiple weighing cells to detect the weight of multiple different medications, the disadvantages of real-time weighing will be more pronounced.
Preferably, the medical drug cart further comprises an alarm unit for emitting an alarm signal when a specific situation occurs. The specific cases include, for example: the medical medicine car is damaged by violence, or the medicine weight is changed abnormally, or the temperature of the refrigerating area is abnormal, or the password is cracked by violence, or the electric quantity of the battery is lower than a set value, communication is abnormal, and the like.
