Technical Field

[0001] This invention relates to the field of infusion pump technology, and in particular to an infusion method, apparatus, equipment and medium of a cascaded infusion pump. Background Technology

[0002] With hospitals increasingly demanding more infusion pumps, the use of multiple infusion pumps in cascades is becoming more common. Currently, communication between multiple infusion pumps in cascaded operation relies on workstations. These workstations typically use wired connections for communication and infusion control. However, this method is limited by wiring connections, requiring the pumps to be located at workstations, which increases the cost of operating multiple infusion pumps in cascades. Therefore, reducing costs is a pressing issue that needs to be addressed when operating multiple infusion pumps in cascades. Summary of the Invention

[0003] In view of this, embodiments of this application provide a method, apparatus, equipment, and medium for cascaded injection pumps to solve the problem of high cost when multiple injection pumps are connected in series.

[0004] In a first aspect, embodiments of this application provide an infusion method using cascaded infusion pumps, wherein each infusion pump is provided with an infrared device above and below it, the infrared device being used to send and receive data, and the infusion method comprising:

[0005] The infusion pumps to be cascaded are obtained, and the infusion pump with the first physical position and the infusion pump with the last physical position are determined based on the heartbeat response packet received by the infrared device in each infusion pump.

[0006] The number of infusion pumps to be cascaded is determined based on the command packet containing physical location information sent by the first infusion pump and the command packet containing physical information received by the last infusion pump.

[0007] For any given infusion pump, if the infusion number of the infusion pump is less than the number, then after the infusion pump completes the infusion, an infusion command packet containing the infusion number is sent to the adjacent infusion pump.

[0008] The preset infusion number of the infusion pump that receives the infusion command packet is compared with the infusion number in the infusion command packet to obtain the comparison result;

[0009] If the comparison results are the same, the infusion pump that received the infusion command packet will start infusion.

[0010] Secondly, embodiments of this application provide an infusion device for cascaded infusion pumps, wherein each infusion pump is provided with an infrared device above and below it, the infrared device being used to send and receive data, and the infusion device comprising:

[0011] The acquisition module is used to acquire the infusion pumps to be cascaded, and to determine the infusion pump with the first physical location and the infusion pump with the last physical location among the infusion pumps to be cascaded based on the heartbeat response packet received by the infrared device in each infusion pump.

[0012] The determining module is used to determine the number of infusion pumps to be cascaded based on the command packet containing physical location information sent by the infusion pump with the first physical location and the command packet containing physical information received by the infusion pump with the last physical location.

[0013] The sending module is used to send an infusion command packet containing the infusion number to the adjacent infusion pump after the infusion pump has completed infusion if the infusion number of the infusion pump is less than the number of pumps.

[0014] The comparison module is used to compare the preset infusion number of the infusion pump that receives the infusion command packet with the infusion number in the infusion command packet to obtain the comparison result;

[0015] The infusion module is used to start infusion when the infusion pump that receives the infusion command packet starts infusion if the comparison results are the same.

[0016] Thirdly, embodiments of this application provide a computer device, the computer device including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the infusion method of the cascaded infusion pump as described in the first aspect.

[0017] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the infusion method of the cascaded infusion pump as described in the first aspect.

[0018] The advantages of this invention compared to the prior art are:

[0019] The process involves acquiring the infusion pumps to be cascaded, identifying the first and last infusion pumps based on the heartbeat response packets received by the infrared devices in each pump, and determining the number of pumps to be cascaded based on the command packets containing physical location information sent by the first pump and the command packets containing physical information received by the last pump. For any given pump, if the pump's infusion number is less than the number of pumps, after the pump completes infusion, it sends an infusion command packet containing the infusion number to the adjacent pump. The preset infusion number of the receiving pump is compared with the infusion number in the command packet. If the comparison results are the same, the receiving pump begins infusion. In this application, by installing an infrared device in the infusion pump for communication and autonomous cascading, the operation of the infusion pump does not require the establishment of a workstation to control the operation of the infusion pump, which reduces costs. In addition, the infrared device has strong anti-electromagnetic interference capability and can better receive the signals sent by each infusion pump, thereby improving the working efficiency of the infusion pump.

[0032] To illustrate the technical solution of the present invention, specific embodiments are described below.

[0033] See Figure 1 This is a schematic flowchart of an injection method using a cascaded injection pump according to an embodiment of the present invention, as shown below. Figure 1 As shown, the injection method of this cascade injection pump may include the following steps.

[0034] S101: Obtain the infusion pumps to be cascaded, and determine the infusion pump with the first physical position and the infusion pump with the last physical position among the infusion pumps to be cascaded based on the heartbeat response packet received by the infrared device in each infusion pump.

[0035] In step S101, the infusion pumps to be cascaded are obtained. The infusion pumps to be cascaded are multiple infusion pumps. Each infusion pump is equipped with an infrared device above and below it. The infrared device is used to receive or send infrared signal data. Based on the heartbeat response packet received by the infrared device in each infusion pump, the infusion pump with the first physical position and the infusion pump with the last physical position in the infusion pumps to be cascaded are determined. The infusion pump with the first physical position is the infusion pump that is arranged first according to the preset setting position, and the infusion pump with the last physical position is the infusion pump that is arranged last according to the preset setting position.

[0036] In this embodiment, the infusion pumps to be cascaded are obtained and arranged vertically relative to each other. The bottom infusion pump is designated as the first infusion pump in physical position, and the top infusion pump is designated as the last infusion pump in physical position. The first infusion pump in physical position sends an infrared signal through the infrared device above it. After the infrared device below the second infusion pump above the bottom infusion pump receives the corresponding infrared signal, the infrared device below the second infusion pump in physical position sends a corresponding infrared signal to the infrared device above the first infusion pump in physical position.

[0037] Based on the infrared signal, data packets are acquired from the corresponding infrared signal. These data packets may include heartbeat packets, command packets, and response packets. Response packets may include heartbeat response packets and command response packets. The heartbeat packet is used to determine whether the upper and lower infusion pumps are connected. If a heartbeat response packet corresponding to the heartbeat packet is received, it is determined that the upper and lower infusion pumps are connected. If no heartbeat response packet corresponding to the heartbeat packet is received, it is determined that the upper and lower infusion pumps are not connected. Based on the heartbeat response packets received by the infrared device in each infusion pump, the infusion pump with the first physical position and the infusion pump with the last physical position in the cascaded infusion pumps are determined. The bottom infusion pump is designated as the pump with the first physical position. The infrared device above the bottom infusion pump sends an infrared signal and receives the response infrared signal sent by the infrared device below the pump with the second physical position. The infrared device below the pump with the first physical position cannot receive response infrared signals sent by other infusion pumps. Based on the heartbeat response packets received by the infrared device in each infusion pump, the infusion pump with the first physical location and the infusion pump with the last physical location in the infusion pump to be cascaded are determined, so as to determine the number of infusion pumps to be cascaded based on the physical location of the infusion pumps.

[0038] Optionally, before determining the infusion pump with the first physical location and the infusion pump with the last physical location among the infusion pumps to be cascaded, based on the heartbeat response packets received by the infrared device in each infusion pump, the method further includes:

[0039] After controlling the infrared device on each infusion pump to send data packets, the header, tail, and length of the data packets received by each infusion pump are verified to obtain the verification result;

[0040] If the verification result is correct, the type of data packet is determined based on the packet header;

[0041] If the data packet type is a heartbeat packet, then the response packet received by the infrared device in each infusion pump is taken as the heartbeat response packet.

[0042] In this embodiment, after the infusion pumps to be cascaded are positioned relative to each other vertically, each infrared device is controlled to send an infrared signal containing a data packet. The data packet received by each infusion pump is verified to obtain a verification result. The data packet includes a header, a valid data length, and a tail. Here, the header can be a marker of the start position of the data packet, the valid data length can be the length of the data in the data packet, and the tail can be a marker of the end position of the data packet.

[0043] It should be noted that when verifying the data packets received by each infusion pump, the validity of the data packet is checked. This involves determining the validity of the packet header. If the header is valid, the length of the received data is obtained, and its validity is then checked. Understandably, the validity of the packet header can be verified using a preset header verification method. This preset header verification method can be set according to actual needs. The system can also determine if the length of the received data is greater than or equal to the maximum data packet length. If the received data length is greater than or equal to the maximum data packet length, the received data length is invalid; if the received data length is less than the maximum data packet length, the received data length is valid. The received data length can be the length of data received after the header validity is confirmed.

[0044] If the length of the received data is valid, then obtain the packet tail. Determine the validity of the packet tail. Specifically, if the length of the received data is valid, it means that the current data packet has been completely received. The packet tail can be identified from the received data, and its validity can be determined. If the packet tail is valid, the verification result is considered correct.

[0045] If the verification result is correct, the data packet type is determined based on the packet header. The packet header contains a message field indicating the data type. The data type indicated by the message field is used to determine the data packet type. If the data packet type is a heartbeat packet, then the response packet received by the infrared device in each infusion pump is taken as the heartbeat response packet.

[0046] In this embodiment, the connection between the infusion pumps is determined based on whether the corresponding heartbeat response packet is received. If the connection is established, infrared communication is performed. If the corresponding heartbeat response packet is not received, it is assumed that the connection between the infusion pumps is not established, and the corresponding heartbeat packet needs to be resent.

[0047] It should be noted that the heartbeat packets are sent periodically according to a preset time period to ensure a continuous connection between the infusion pumps.

[0048] Optionally, based on the heartbeat response packet received by the infrared device in each infusion pump, the infusion pump with the first physical location and the infusion pump with the last physical location in the cascaded infusion pumps are determined, including:

[0049] If the infrared device above the infusion pump receives a heartbeat response packet, but the infrared device below does not receive a heartbeat response packet, then the corresponding infusion pump is the infusion pump with the first physical location.

[0050] If the infrared device above the infusion pump does not receive a heartbeat response packet, but the infrared device below receives a heartbeat response packet, then the corresponding infusion pump is the one whose physical location is the last infusion pump.

[0051] In this embodiment, each infusion pump is equipped with an infrared device above and below it. Each infrared device is used to send and receive infrared signals. If both the infrared devices above and below the infusion pump can receive the corresponding infrared signal, the infusion pump is considered to be in the middle position in the cascade. If the infrared devices above and below the infusion pump only receive the infrared signal once, the infusion pump is considered to be the first or last in the cascade. If the infrared device above the infusion pump receives the infrared signal (i.e., a heartbeat response packet) but the infrared device below does not receive the infrared signal (i.e., a heartbeat response packet), the corresponding infusion pump is the first infusion pump in physical position. If the infrared device above the infusion pump does not receive the infrared signal (i.e., a heartbeat response packet) but the infrared device below receives the infrared signal (i.e., a heartbeat response packet), the corresponding infusion pump is the last infusion pump in physical position.

[0052] S102: Determine the number of infusion pumps to be cascaded based on the command packet containing physical location information sent by the first infusion pump and the command packet containing physical information received by the last infusion pump.

[0053] In step S102, after determining the first and last infusion pumps in physical location, the number of infusion pumps to be cascaded is determined. The first infusion pump sends a command packet containing physical location information. Each infusion pump can determine its own physical location based on the physical location of the previous infusion pump it receives. When the last infusion pump receives the command packet containing physical location information, it can determine the specific physical location of the last infusion pump, thereby determining the number of infusion pumps to be cascaded.

[0054] In this embodiment, each infusion pump sends its corresponding physical information to the next infusion pump whose physical location is next. The next infusion pump determines its physical location based on the received command packet containing the physical information. Specifically, the infusion pump at the first physical location begins sending command packets via its upper infrared device, communicating with the infrared device below the next infusion pump. When the infrared device below the next infusion pump receives the command packet sent by the first infusion pump via its upper infrared device, it parses the command packet to extract the corresponding physical location information, thereby determining the physical location of the next infusion pump. Then, the infrared device above the next infusion pump sends a command packet containing the physical location information to the next infusion pump, and so on, until the last infusion pump receives its corresponding command packet, thus determining the physical location of the last infusion pump.

[0055] Optionally, the number of infusion pumps to be cascaded is determined based on the command packet containing physical location information sent by the first infusion pump and the command packet containing physical information received by the last infusion pump, including:

[0056] For any infusion pump, a command packet containing physical location information is sent through an infrared device above the infusion pump. Based on the command packet, the physical information of the infusion pump that receives the command packet is determined.

[0057] After receiving a command packet containing physical location information, the last infusion pump in physical location determines the physical location information of the last infusion pump and obtains the number of infusion pumps to be cascaded based on the physical location information of the last infusion pump.

[0058] In this embodiment, for any infusion pump, a command packet containing physical location information is sent via an infrared device above the pump. Based on the command packet, the physical information of the receiving pump is determined. For example, the pump at the first physical location starts sending command packets via its upper infrared device, communicating with the infrared device below the next pump. When the infrared device below the next pump receives the command packet sent by the pump at the first physical location via its upper infrared device, it parses the command packet to extract the corresponding physical location information (i.e., the first physical location). The next pump's corresponding physical location is the second. The second pump then packages this physical location information into a command packet and sends it via its upper infrared device to the next pump, the pump at the third physical location. After the last pump receives the command packet containing its physical location information, its physical location is determined. Based on this physical location information, the number of pumps to be cascaded is calculated. When the last infusion pump receives a command packet containing physical location information from the previous infusion pump, it determines the physical location of the last infusion pump based on the physical location information in the parsed command packet. For example, when the last infusion pump receives a command packet from the third infusion pump, it determines that the last infusion pump is the fourth infusion pump. That is, the infusion pumps to be cascaded include 4 infusion pumps.

[0059] Optionally, after determining the number of infusion pumps to be cascaded, the method further includes:

[0060] Based on the physical information of each infusion pump, the number is sent sequentially to each infusion pump, so that each infusion pump knows the number of infusion pumps to be cascaded.

[0061] In this embodiment, after determining the number of infusion pumps to be cascaded, the number of infusion pumps to be cascaded is sequentially sent downwards from the last infusion pump in physical location, so that each infusion pump can obtain the number of infusion pumps to be cascaded. For example, if the number of infusion pumps to be cascaded is 4, the last infusion pump in physical location sends an infrared signal containing the number of pumps to be cascaded to the third infusion pump in physical location via the infrared device below. The third infusion pump in physical location receives the corresponding infrared signal via the infrared device above. After receiving the corresponding infrared signal, the third infusion pump in physical location sends an infrared signal containing the number of pumps to be cascaded to the second infusion pump in physical location via the infrared device below. The second infusion pump in physical location receives the corresponding infrared signal via the infrared device above. After receiving the corresponding infrared signal, the second infusion pump in physical location sends an infrared signal containing the number of pumps to be cascaded to the first infusion pump in physical location via the infrared device below. The first infusion pump in physical location receives the corresponding infrared signal via the infrared device above. The number of infusion pumps to be cascaded can be obtained from the four cascaded pumps.

[0062] S103: For any injection pump, if the injection number of the injection pump is less than the number of pumps, then after the injection pump completes the injection, an injection command packet containing the injection number is sent to the adjacent injection pump.

[0063] In step S103, for any infusion pump, if the infusion number of the infusion pump is less than the number of pumps, that is, the infusion pump is not the last pump to perform infusion, then after the infusion pump completes infusion, an infusion command packet containing the infusion number is sent to the adjacent infusion pumps so that the remaining infusion pumps can perform infusion according to the infusion command in the infusion command packet. The adjacent infusion pumps are the upper infusion pump and the lower infusion pump of the corresponding infusion pump. The infusion number is the infusion sequence number of the cascaded infusion pumps during the infusion process. For example, if the second infusion pump needs to start infusion after the first infusion pump in the cascaded infusion pumps has completed infusion, then the infusion number in the infusion command packet is 2. If the third infusion pump needs to perform infusion after the second infusion pump in the cascaded infusion pumps has completed infusion, then the infusion number in the infusion command packet is 3.

[0064] In this embodiment, after the cascaded infusion pumps are completed, a cascaded infusion pump is obtained, and each infusion pump communicates with each other via infrared signals. During infusion, a corresponding infusion order is set for each infusion pump, and infusions are performed sequentially according to this order until each infusion pump has finished infusion. For example, the infusion pump with the first infusion number starts infusion. After the first infusion pump array is completed, it sends an infusion command packet to the adjacent infusion pumps. When the infusion pump with the second infusion number receives the infusion command packet sent by the first infusion pump, the second infusion pump begins infusion.

[0065] It should be noted that the infusion sequence can be the same as or different from the physical positional order of the cascaded infusion pumps. For example, the physical positional order of the cascaded infusion pumps from bottom to top might be: first infusion pump, second infusion pump, third infusion pump, and fourth infusion pump. The infusion sequence from bottom to top could be: infusion pump number 1, infusion pump number 2, infusion pump number 3, and infusion pump number 1; or it could be: infusion pump number 2, infusion pump number 3, infusion pump number 1, and infusion pump number 4. That is, the connection of the cascaded infusion pumps according to their physical positional order is 1-2-3-4, but the connection according to the infusion sequence could be 1-2-3-4 or 2-3-1-4. In other words, the infusion sequence of the pump physically located as 1 might be 2.

[0066] S104: Compare the preset infusion number of the infusion pump that receives the infusion command packet with the infusion number in the infusion command packet to obtain the comparison result.

[0067] In step S104, during the cascaded infusion pump infusion process, each infusion pump infuses according to its corresponding infusion sequence. After each infusion pump completes its infusion, the system determines whether to proceed with the next infusion pump infusion sequence based on a preset infusion number in the infusion sequence. The preset infusion number of the infusion pump receiving the infusion command packet is compared with the infusion number in the infusion command packet to obtain a comparison result. This comparison result is used to determine whether the next infusion pump should proceed with infusion.

[0068] In this embodiment, the preset infusion number of the infusion pump receiving the infusion command packet is compared with the infusion number in the infusion command packet to obtain a comparison result. The preset infusion number is a pre-set infusion order for each infusion pump in the cascaded infusion pumps, and the infusion number is the infusion sequence number of the cascaded infusion pump during the infusion process. When comparing the preset infusion number of the infusion pump receiving the infusion command packet with the infusion number in the infusion command packet, it is determined whether the preset infusion number of the infusion pump receiving the infusion command packet and the infusion number in the infusion command packet are equal. If they are equal, the corresponding infusion pump starts infusion; if they are not equal, an infusion pump whose preset infusion number and the infusion number in the infusion command packet are found and infused.

[0069] S105: If the comparison results are the same, the infusion pump that received the infusion command packet will start infusion.

[0070] In step S105, if the comparison results are the same, that is, the preset infusion number of the infusion pump receiving the infusion command packet is the same as the infusion number in the infusion command packet, then the infusion pump corresponding to receiving the infusion command packet starts infusion.

[0071] In this embodiment, it is determined whether the comparison results are the same. If the comparison results are the same, the infusion pump that received the infusion command packet starts infusion. For example, if the preset infusion number of the infusion pump that received the infusion command packet is 2, and the infusion number in the infusion command packet is also 2, it is considered that one of the cascaded infusion pumps has completed infusion, and the second infusion pump starts infusion. The infusion pump with the second infusion sequence needs to perform infusion, that is, the infusion pump with the preset infusion number 2 starts infusion.

[0072] Optionally, after comparing the preset infusion number of the infusion pump receiving the infusion command packet with the infusion number in the infusion command packet and obtaining the comparison result, the method further includes:

[0073] If the comparison results are different, the infusion pump that received the infusion command packet sends an infusion command packet containing the infusion number to the adjacent infusion pump.

[0074] In this embodiment, if the comparison results are different, the infusion pump receiving the infusion command packet sends an infusion command packet containing the infusion number to the adjacent infusion pump until the preset infusion number of the infusion pump receiving the infusion command packet is the same as the infusion number in the infusion command packet. For example, the physical position order of the cascaded infusion pumps is 1-2-3-4 from bottom to top, that is, infusion pump 1, infusion pump 2, infusion pump 3 and infusion pump 4. According to the preset infusion order, the preset infusion number corresponding to each infusion pump is in the following order: infusion number 2, infusion number 3, infusion number 4 and infusion number 1. That is, the infusion number of infusion pump 1 is 2, the infusion number of infusion pump 2 is 3, the infusion number of infusion pump 3 is 4 and the infusion number of infusion pump 4 is 1. Infusion pump 4 begins infusion. After infusion is completed, infusion pump 2 begins infusion. Infusion pump 4 sends infusion command packet number 2 to infusion pump 3 via the infrared device below. After receiving the corresponding infusion command packet, infusion pump 3 compares the infusion number in the command packet with the infusion number in infusion pump 3. If the comparison result is different, infusion pump 3 sends infusion command packet number 2 to infusion pump 2 via the infrared device below. After receiving the corresponding infusion command packet, infusion pump 2 compares the infusion number in the command packet with the infusion number in infusion pump 2. If the comparison result is different, infusion pump 2 sends infusion command packet number 2 to infusion pump 1 via the infrared device below. After receiving the corresponding infusion command packet, infusion pump 1 compares the infusion number in the command packet with the infusion number in infusion pump 1. If the comparison result is the same, infusion pump 1 begins infusion.

[0075] The process involves acquiring the infusion pumps to be cascaded, identifying the first and last infusion pumps based on the heartbeat response packets received by the infrared devices in each pump, and determining the number of pumps to be cascaded based on the command packets containing physical location information sent by the first pump and the command packets containing physical information received by the last pump. For any given pump, if the pump's infusion number is less than the number of pumps, after the pump completes infusion, it sends an infusion command packet containing the infusion number to the adjacent pump. The preset infusion number of the receiving pump is compared with the infusion number in the command packet. If the comparison results are the same, the receiving pump begins infusion. In this application, by installing an infrared device in the infusion pump for communication and autonomous cascading, the operation of the infusion pump does not require the establishment of a workstation to control the operation of the infusion pump, which reduces costs. In addition, the infrared device has strong anti-electromagnetic interference capability and can better receive the signals sent by each infusion pump, thereby improving the working efficiency of the infusion pump.

[0076] See Figure 2 , Figure 2 This diagram illustrates the structural block diagram of the infusion device for a cascaded infusion pump provided in an embodiment of this application.
