Description

Specification Title: A method and system for the management of special drugs

[0001] Embodiments of the present invention relate to the field of smart medical care, and in particular, to a method and system for managing special drugs.

[0002] Hospitals are an important place to save lives and promote humanitarianism. In order to prevent sudden disasters such as mine disasters and earthquakes, the demand for special drugs for a large number of critically ill patients, or for strategic considerations, the hospital will strategically reserve or store some special drugs. However, due to poor management or other reasons in some hospitals, it is not known that the storage environment of these special drugs has become bad, and even where they are stored, so that the quality of the products after storage in the long room is deteriorated, and it is urgent to use them. Some role.

[0003] In order to solve the above problems, the method used in the industry is to manage the special medicines by positioning, that is, through some positioning technology, the storage place of the special medicines can be obtained, so that the storage environment becomes bad and moved to New place to store. Currently, Global Positioning (Global Positioning)

System, GPS) and Radio Frequency Identification (RFID) are two kinds of typical positioning technologies. The industry has GPS or RFID into the hospital for special drug management.

[0004] However, these two positioning technologies have inherent limitations for the management of special drugs in hospitals. Taking GPS as an example, its satellite signal is easily blocked by obstacles such as buildings in the hospital and cannot be accurately located. In some hospitals, the floor space is huge, the buildings are relatively high, and special drugs that need to be positioned to relatively small sizes are needed. Obviously unrealistic, while RFID technology is suitable for the positioning of small-sized objects, but the RFID signal is also more susceptible to environmental interference, and can not reflect the actual movement of the label, for example, a special medicine from a Local handling (there is illegal handling). To another location, RFID does not reflect this process. Finally, even if the two positioning methods can be targeted to the storage of special medicines, the hospital's relevant management personnel may still be unaware of the environment in which the storage location becomes bad.

[0005] Therefore, new technologies are needed to overcome the above-mentioned deficiencies in the management of special drugs.

Embodiments of the invention

[0040] In order to make the objects, technical solutions and beneficial effects of the present invention more clear, the following The present invention will be further described in detail. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0041] Embodiments of the present invention provide a system for managing a special drug, the system comprising a positioning server, an electronic tag fixed on a special drug outer package, and at least three interconnected and synchronized base stations; Transmitting an ultra-wideband pulse signal to the at least three base stations; the base station is configured to receive an ultra-wideband pulse signal sent by the electronic tag, and send an engraving of receiving the ultra-wideband pulse signal to the positioning server The positioning server is configured to locate a special medicine to which the electronic label is fixed according to a positioning algorithm and an engraving of each of the at least three base stations to receive the ultra-wideband pulse signal, where the special medicine storage place is located If the environmental parameters exceed the standard, an alarm message is sent to the central server. Embodiments of the present invention also provide corresponding methods for managing specific drugs. The details are described below separately.

Referring to FIG. 1, FIG. 1 is a schematic diagram of an implementation process of a method for managing a special drug according to Embodiment 1 of the present invention. The method mainly includes the following steps S101 to S103:

[0043] S101. The electronic tag sends an ultra-wideband pulse signal to at least three base stations.

[0044] The so-called special drug is a relative concept, which does not necessarily refer to an expensive drug; in fact, in the embodiment of the present invention, there are special requirements such as strategic reserve, large reserve, or high storage environment requirements. All drugs can be considered as special drugs. Of course, in the actual application scenario, each hospital can also treat any drug as a special drug according to its own needs, thereby managing by using the technical solution provided by the present invention.

[0045] In an embodiment of the invention, the electronic tag is attached to a special drug that is managed by the hospital. The electronic tag can transmit an Ultra Wide Band (UWB) pulse signal periodically without direction or in any direction. It should be noted that “fixed” here means that the electronic label is attached, mounted or soldered in various manners on the outer packaging of the special medicine to be managed, and it is not easy to fall off naturally from the outer packaging of these special medicines. Once it has been artificially removed from these special medicine packagings in a destructive manner, the electronic label will issue an alarm message. As for the special drug outer packaging, it may be a bottle or a box directly loaded with the special medicine, or an outer packaging box for storing the special medicine. The invention has no limitation on the form of the outer packaging of the special medicine. The at least three base stations of the embodiments of the present invention may be deployed in any jurisdiction of the hospital, and the specific location is limited to the ultra-wideband pulse signal of sufficient strength to be transmitted by the electronic tag fixed on the special medicine. [0046] It should be noted that the electronic tag transmits an ultra-wideband pulse signal to at least three base stations. In theory, a wireless communication signal that transmits information in any frequency band of 500 MHz in the spectrum of 3.1 GHz to 10.6 GHz can be called an ultra-wideband pulse signal. In the embodiment of the present invention, the ultra-wideband pulse signal may be a signal carried by an electronic tag occupying any frequency band of 500 MHz in 3.1 GHz to 10.6 GHz, and a non-sinusoidal narrow pulse of nanosecond order is used for the ultra-wideband pulse signal. Transmit data, with frequency bandwidth (500 MHz), multi-channel, low power consumption, low interference, high safety factor and coexistence with existing spectrum, that is, it will not interfere with existing and future ultra-wideband communication applications. It can not only achieve high-precision positioning of special medicines with small sizes in hospitals, but also enhance the stability of positioning.

[0047] It should be noted that, in the embodiment of the present invention, at least three base stations are interconnected and synchronized, and the interconnection method may be a wired network interconnection or a wireless network interconnection, where the wireless network includes a WiFi network, a 3G network, a 4G network, and One of the 5G networks. As for the synchronization between the base stations, any one of the at least three base stations may send a synchronization pulse to the at least two base stations directly or through the base station directly connected by the data exchange device, thereby completing the base station and the other at least two base stations. Synchronization between.

[0048] S102. The base station receives the ultra-wideband pulse signal sent by the electronic tag, and sends the engraving of the ultra-wideband pulse signal to the positioning server.

[0049] In the embodiment of the present invention, the positioning server may be deployed in a building of a hospital, for example, a positioning server is deployed every two floors in a building. The positioning server may directly connect to one of the at least three base stations or the plurality of base stations, or the positioning server may connect one of the at least three base stations or the plurality of base stations through the data switching device.

[0050] In the embodiment of the present invention, the positioning server connects one of the at least three base stations or the plurality of base stations through the data switching device, and includes the following four connection modes:

[0051] Manner 1: The base station and the base station are connected by a network cable, and one or more base stations are connected to the data distribution port of the router through a network cable, and the data distribution port of the router is connected to the positioning server through the network cable;

[0052] Manner 2: a network cable is connected between the base station and the base station, and one or more base stations are connected to the data distribution port of the switch through the network cable, and the data distribution port of the switch is connected to the positioning server through the network cable;

[0053] Method 3: The optical connection is used between the base station and the base station, and one or more base stations are connected to the input end of the optical transceiver through the optical fiber, and the output end of the optical transceiver is connected to the positioning server through the network cable;

[0054] Method 4: A fiber connection is used between the base station and the base station, and one or more base stations are connected to the optical fiber through the optical fiber. The input end of the transceiver, the output end of the optical transceiver, is connected to the positioning server through a network cable.

[0055] For the case where the positioning server is directly connected to one of the at least three base stations or the plurality of base stations, the base station transmitting the address of receiving the ultra-wideband pulse signal to the positioning server may be: at least two of the at least three base stations The base station transmits the engraving of the ultra-wideband pulse signal respectively sent by the electronic tag to any one of the three base stations, and the engraving of each of the base stations to receive the ultra-wideband pulse signal is directly sent to the positioning server, or And each of the at least three base stations directly sends the engraving of the ultra-wideband pulse signal sent by the electronic tag to the positioning server; and the positioning server connects one of the at least three base stations or the plurality of base stations through the data switching device. In this case, the base station transmitting the address of receiving the ultra-wideband pulse signal to the positioning server may be: at least two of the at least three base stations transmitting the engraving of the ultra-wideband pulse signal sent by the respective receiving electronic tags to the three base stations. Any one of the base stations, each of which will be each The engraving of the base station receiving the ultra-wideband pulse signal is sent to the positioning server through the data exchange device, or each of the at least three base stations sends the engraving of the ultra-wideband pulse signal sent by the respective receiving electronic tag to the positioning through the data exchange device. server.

[0056] S103. The positioning server locates the special medicine with the electronic label fixed according to the positioning algorithm and the engraving of each of the at least three base stations receiving the ultra-wideband pulse signal, and the environmental parameter of the special medicine storage place exceeds the standard, to the center. The server sends an alarm message.

[0057] In the embodiment of the present invention, the positioning server calculates the actual coordinate of the special medicine with the electronic label fixed by using a positioning algorithm according to the engraving of each of the at least three base stations receiving the electronic tag to transmit the ultra-wideband pulse signal. Thereby positioning these special drugs. As for the positioning algorithm, it can be one of the Time Of Arrival (TOA) algorithm and the Time Difference Of Arrival (TDOA) algorithm, or it can be other positioning algorithms.

[0058] It should be noted that, in the embodiment of the present invention, the actual coordinate of the managed special medicine may be the actual two-dimensional coordinates of the managed special medicine, or may be the actual medicine to be managed. The three-dimensional coordinates, which depend on how many base stations are used to transmit the ultra-wideband pulse signals transmitted by the respective electronic tags that are fixed by the managed special drugs for the same managed special drug. For example, if the engraving of the ultra-wideband pulse signals transmitted by the respective receiving electronic tags transmitted by the three base stations is used, the positioning server calculates the actual two-dimensional coordinates of the managed special drugs, if Four or four Each of the above base stations receives the engraving of the ultra-wideband pulse signal transmitted by the electronic tag, and the positioning server calculates the actual three-dimensional coordinates of the managed special drug; a typical embodiment uses four or four Each of the above base stations receives the engraving of the ultra-wideband pulse signal transmitted by the electronic tag to calculate the actual coordinate of the managed special drug.

[0059] It should be noted that, in the embodiment of the present invention, the positioning server stores various special medicines to store standard environmental parameters or safety environment parameters, and the electronic label has the ability to collect environmental parameters of the special medicine storage place. For example, electronic tags can have built-in temperature sensors and humidity sensors. With these temperature sensors and humidity sensors, electronic tags can collect actual environmental parameters such as temperature and humidity of a particular drug storage site, and then pass ultra-wideband pulse signals or other forms. The signal transmits the actual environmental parameters such as temperature and humidity of the place where these special drugs are stored to the positioning server. After receiving the actual environmental parameters of these special drugs, the positioning server compares it with the standard environmental parameters or safety environment parameters of the special drug. Once the comparison result is exceeded, for example, the actual temperature of the storage site exceeds the storage standard. If the temperature and/or the implemented humidity of the storage place exceeds the storage standard humidity, etc., the central server sends an alarm message to indicate that the environment in which the special drug is stored is bad.

The method for managing a special medicine as exemplified in FIG. 1 further includes: receiving, by a central server connected to the positioning server, an actual environmental parameter of the special medicine storage place, the alarm information sent by the positioning server, and collecting the positioning. The positioning information of the server for positioning the special medicine to which the electronic label is fixed. In the embodiment of the present invention, the central server may be a server located in a central monitoring room of the hospital, or a server deployed outside the hospital and managing the upper-level organization of the hospital, and the central server may be connected by wire or wirelessly. The positioning server connection in the hospital is used to collect the positioning information of the positioning server for positioning the special medicine with the electronic label fixed, so that the relevant personnel of the hospital can retrieve or query when needed.

[0061] In one embodiment of the present invention, the method for managing a hospital special medicine as exemplified in FIG. 1 further includes: querying a terminal connected to the central server to inquire about storage location and status information of a special medicine to which the electronic label is fixed. . The query terminals can be connected to the central server by wire or wirelessly, and can be a fixed terminal such as a personal computer (PC) or a mobile terminal such as a smart phone or a tablet. By querying the human-computer interaction interface provided by the terminal, the hospital related personnel can input the number or identity information of the special medicines managed in the hospital, and the specific medicine can be inquired. Store location and status information, for example, where in the hospital, the current temperature of the storage location, humidity, and other environmental parameters.

[0062] As can be seen from the method for special drug management illustrated in FIG. 1 above, the positioning server can select a special drug to which the electronic tag is fixed according to the positioning algorithm and the engraving of the ultra-wideband pulse signal by each of the at least three base stations. The positioning is performed, and when the environmental parameter of the special drug storage place exceeds the standard, the alarm information is sent to the central server. Since an electronic tag fixed to a special drug transmits an ultra-wideband pulse signal, it has a frequency bandwidth, a multi-channel, a low power consumption, is not susceptible to interference, has a high safety factor, and can coexist with an existing spectrum. Therefore, on the one hand, Compared with the existing GPS positioning, the technical solution provided by the present invention is not easily affected by environmental interference, and even a special medicine with a small size in a hospital can be highly accurately positioned; on the other hand, because it is fixed to a special The electronic label of the medicine is to transmit the ultra-wideband signal, and the positioning server can track and locate the special medicine. Therefore, compared with the RFID positioning technology, the technical solution provided by the invention can know the special medicine in the hospital. Where and where the actual environmental parameters of the place of storage are, so that it can be managed more effectively.
