When the inventor designs the present invention, the inventor first obtains the position information of the medical device to be searched, and then performs path planning based on the current position information of the searching person and the obtained position information of the medical device to be searched, and the searching person can find the medical device to be searched along the planned path, which is described in detail below.
Referring to fig. 1, an embodiment of the present invention discloses a path planning method for searching hospital equipment (hereinafter referred to as a path planning method), which may include steps 100 to 400.
Step 100: and receiving the in-hospital equipment searching request through the user side. The user terminal may be a desktop computer, a notebook computer, a smart phone, a tablet computer, or a specific user terminal, and in some embodiments, the user terminal may preferably be a terminal with certain portability or mobility, such as a smart phone and a tablet computer.
Step 200: and acquiring the position information of the equipment in the hospital.
Step 300: and acquiring the position information of the user side.
Step 400: and planning a path from the position of the user end to the position of the in-hospital equipment on a preset in-hospital map based on the position information of the user end and the position information of the in-hospital equipment.
In the concrete implementation of the present invention, a plurality of first radios may be provided in the yard, each device in the yard is provided with a second radio, and the position information of the device in the yard is calculated by a device having a calculation capability, such as a server or a user side, through the connection between the first radio and the second radio, and the device type and/or the device identifier of the device in the yard are/is acquired, so that the positioning of the device in the yard can be realized. It should be noted that the device identifier refers to an ID of the device in the hospital, and may be, for example, a serial number, and the device in the hospital and the device identifier are in a one-to-one correspondence relationship; the device type refers to the type of the in-hospital device, for example, the device type is a transfer monitor, a portable defibrillator, an infrared ear thermometer, a portable color Doppler ultrasound device, and the like, and thus the device type generally corresponds to a plurality of in-hospital devices.
Specific ways of in-hospital positioning several examples are tried below.
For example, the positioning of the devices in the hospital can be realized through the WIFI indoor positioning technology. In some embodiments the first wireless device and the second wireless device are connected via WIFI. When the in-hospital equipment is positioned, the in-hospital equipment is more accurately triangulated through a difference algorithm based on the wireless signal strength of the second wireless device and the three first wireless devices of the in-hospital equipment. Alternatively, the signal intensity of each location point of the huge amount may be recorded in advance, and the signal intensity of the second radio of the current in-hospital device may be compared with the huge amount data recorded in advance to determine the location information of the current in-hospital device.
For example, the invention can also realize the positioning of the devices in the hospital by the ultra-wideband UWB indoor positioning technology. The first and second radios in some embodiments are communication units that can receive and transmit very narrow pulses with nanosecond or subnanosecond range to transmit data. When the in-hospital equipment is located, anchor nodes and bridge nodes with known positions, which are arranged in advance, are used for communicating with the current in-hospital equipment and determining the position information of the in-hospital equipment by using a triangulation location technology, or alternatively, the signal strength of each position point of a huge amount can be recorded in advance, and the signal strength of a second wireless device of the current in-hospital equipment is compared with the data of the huge amount recorded in advance to determine the position information of the current in-hospital equipment.
For example, the invention can also realize the positioning of the devices in the hospital by the Bluetooth indoor positioning technology. In some embodiments the first wireless device and the second wireless device are connected via bluetooth. The indoor positioning technology of bluetooth is similar with the indoor positioning technology of WIFI, and what indoor positioning technology of bluetooth utilized is the signal intensity of bluetooth only, and what indoor positioning technology of WIFI utilized is the signal intensity of WIFI, no longer gives unnecessary here to the indoor positioning technology of bluetooth repeated description.
For example, the invention can also realize the positioning of the devices in the hospital by the RFID positioning and positioning technology. For example, in some embodiments, the first wireless device is an RFID reader, and the second wireless device is an RFID tag, and characteristic information of the RFID tag, such as received signal strength, and a device type and/or a device identification of a device in a hospital having the RFID tag, may be read by the RFID reader; and then the position of the RFID label or the in-hospital equipment with the RFID label is determined by adopting a neighbor method, a multi-edge positioning method, received signal strength and other methods.
For example, the present invention may also be implemented by an infrared indoor positioning technology to position the devices in the hospital, for example, the first wireless device is an optical sensor for receiving and sensing infrared rays, and the second wireless device is for emitting infrared rays; the in-hospital device transmits the modulated infrared rays through the second radio, the first radio arranged in the hospital receives the infrared rays and converts the infrared rays into electric signals, and the position of the in-hospital device can be calculated based on the electric signals.
In a specific embodiment, the existing technology or future indoor positioning technology can be selected according to requirements to obtain the position information of the equipment in the hospital, so that the equipment in the hospital can be positioned.
In practical situations, a user sometimes only needs to search for one medical device, and sometimes needs to search for multiple medical devices at the same time, and the present invention can be applied to a case where the user searches for one medical device, and can also be applied to a case where the user searches for multiple medical devices, so that in some embodiments, the in-hospital device search request in step 100 can be used to search for one in-hospital device needed by the user, and in other embodiments, the in-hospital device search request in step 100 can be used to search for multiple in-hospital devices needed by the user, which will be described in the following cases.
In some embodiments the in-home device lookup request in step 100 is for finding one in-home device desired by the user, and in some embodiments the in-home device lookup request includes one or both of information of the device type and the device identification.
In some implementations, the user side may have an input box as shown in fig. 2(a) for the user to input device identifiers, where each device identifier corresponds to a specific device, so that the user inputs the device identifier and then clicks the search to complete the input of the in-hospital device search request; an example of an input device identified as N22-001 is shown. Referring to fig. 3, a system diagram of a hardware implementation of the path planning method is shown, which may be referred to as a path planning system. The server and the like can regularly acquire the equipment information and the position information of the equipment in the hospital, wherein the equipment information comprises equipment types and/or equipment identifications and the like; thus, when the server receives the in-home device search request through the user side, the server finds the location information of the corresponding in-home device based on the device identifier included in the in-home device search request — for example, when the server receives the in-home device search request as illustrated in fig. 2(a), the server finds the location information of the device identifier N22-001. After the location information of the corresponding in-hospital device is found, since the location information of the user end can be obtained, a path from the user end location to the in-hospital device location is planned on a preset in-hospital map based on the location information of the user end and the location information of the in-hospital device, for example, a path from the user end location to the in-hospital device needed by the user is planned on the preset in-hospital map, so that the path is the shortest path or the path with the least time consumption, for example, still taking fig. 2(a) as an example, a shortest path from the user end to a device identifier N22-001 or the path with the least time consumption is planned. It should be noted that, in fig. 3, the path planning of step 400 is completed at the server, and then the server sends the path planning result to the user side for displaying, but it is understood that step 400 may also be completed at the user side, in which case, the server sends the acquired location information of the in-hospital device to the user side based on the device search request, and the user side completes the path planning based on the in-hospital device and the location information of the user side.
In some embodiments, the user terminal may have a selection box as shown in fig. 2(b) for the user to select the device type; the figure shows the user selecting the type of portable defibrillator. Similarly, the server and the like can acquire the equipment information and the position information of the equipment in the hospital at regular time; thus, when the server receives the in-home device search request through the user terminal, based on the device type included in the in-home device search request, the location information of the in-home device of the device type is found — for example, when the server receives the in-home device search request as illustrated in fig. 2(b), the server searches for the location information of the device type, which is the portable defibrillator. After the location information of the corresponding in-hospital device is found, the location information of the user terminal can be obtained, so that a path from the user terminal to the location of the in-hospital device is planned on a preset in-hospital map based on the location information of the user terminal and the location information of the in-hospital device, for example, a path from the user terminal to the in-hospital device required by the user is planned on the preset in-hospital map, so that the path is the shortest path or the path with the least time consumption. It should be noted that, since the device types may correspond to multiple pieces of in-hospital equipment at the same time, the server may find the location information of multiple pieces of in-hospital equipment of the same device type at the same time, so when performing path planning based on the location information of the user end and the location information of the in-hospital equipment, it may be to select one piece of in-hospital equipment closest to the user end to perform a path rule, for example, select one piece of in-hospital equipment closest to the user end to plan a path from the user end location to the user piece of in-hospital equipment on a preset in-hospital map, so that the path is the shortest path or the path with the least time consumption; or planning paths respectively reaching the in-hospital equipment according with the equipment types from the user end position on a preset in-hospital map, and then selecting a shortest or least time-consuming path as a final planned path.
The in-hospital device lookup request in step 100 may be used in some embodiments to lookup a number of in-hospital devices desired by the user, and in some embodiments the in-hospital device lookup request contains one or both of device type information and device identification.
In some implementations, the user side may have an interface as shown in fig. 4, the devices in the hospital of the same device type are displayed together, a check box is provided before the device identifier of the device in the hospital, when the check box is checked, it indicates that the device needs to be searched, the user checks the corresponding device in the hospital by checking one or more check boxes before the device identifier, and then clicks the search, thereby completing the input of the request for searching the device in the hospital; the user is shown checking for a transport monitor identified as N22-002 and a portable defibrillator identified as BD-001. Similarly, the server and the like can regularly acquire the device information and the position information of the devices in the hospital, wherein the device information comprises the device type, the device identification and the like; thus, when the server receives the in-home device search request through the user terminal, the server searches for the location information of the corresponding in-home device based on the device identifier included in the in-home device search request — for example, when the server receives the in-home device search request as illustrated in fig. 4, the server searches for the location information of the transit monitor having the device identifier N22-002 and the portable defibrillator having the device identifier BD-001. After the location information of the corresponding in-hospital device is found, the location information of the user terminal can be obtained, so that a path from the user terminal to the location of the in-hospital device is planned on a preset in-hospital map based on the location information of the user terminal and the location information of the in-hospital device, for example, paths from the user terminal to a plurality of in-hospital devices required by the user are planned on the preset in-hospital map in sequence, and the path is the shortest path or the path with the least time consumption.
In some embodiments, the user may select the device type to be searched by selecting the check box before the device type in fig. 4, and then click the search to complete the input of the in-hospital device search request. Similarly, the server and the like can acquire the equipment information and the position information of the equipment in the hospital at regular time; thus, when the server receives the in-home device search request through the user side, the position information of the in-home device of the device type is searched based on the device type contained in the in-home device search request. After the location information of the corresponding in-hospital device is found, the location information of the user terminal can be obtained, so that a path from the user terminal to the location of the in-hospital device is planned on a preset in-hospital map based on the location information of the user terminal and the location information of the in-hospital device, for example, paths from the user terminal to a plurality of in-hospital devices required by the user are planned on the preset in-hospital map in sequence, and the path is the shortest path or the path with the least time consumption. It should be noted that, since the device types may correspond to multiple in-home devices at the same time, when the user selects multiple device types to search, the server may search for location information of multiple in-home devices of the same device type for each device type, and therefore, when path planning is performed based on the location information of the user side and the location information of the in-home devices, an obtained path planning result is a path from the user side, and the path may pass through one device of each device type required by the user.
In some embodiments, the present invention further obtains location information of the user side in real time; when the user side is determined to reach one of the in-hospital devices required by the user, the position information of the remaining in-hospital devices required by the user is obtained again, and the path from the current position of the user side to the remaining in-hospital devices required by the user is planned again, so that the path is the shortest path or the path consuming the least time.
It will be understood by those skilled in the art that fig. 2 and fig. 4 are only examples of the user terminal receiving the device search request input by the user, and are not intended to limit the user terminal to receive the device search request input by the user only in these ways.
In an embodiment, the planning a path from a user end location to an in-hospital device location on a preset in-hospital map according to the present invention may include: and planning a path according to the elevator, the stairs and/or the current time contained in the path on a preset in-home map so as to enable the path to be the shortest path or the path with the least time consumption.
The medical staff can quickly search and retrieve the corresponding equipment according to the equipment information such as the equipment type, the equipment identification and the like, so that the medical staff can find the corresponding medical equipment as soon as possible, and the maintenance staff of the equipment department can find all the equipment at one time and formulate the optimal maintenance route.
