Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth one-to-one pairing mode is used for medical instrument data transmission, then data security and connection stability are improved, but operation complexity increases and transmission efficiency decreases
Solution Approach 1:
The patent applies universality by enabling the medical instrument to broadcast therapy data to multiple terminal devices simultaneously through Bluetooth broadcast mode, eliminating the need for separate one-to-one pairing for each device. This allows any terminal device to receive data without complex pairing procedures, significantly improving ease of operation while maintaining data transmission reliability through the standardized Bluetooth protocol
2Reliability
If Bluetooth one-to-one pairing mode is used for medical instrument data transmission, then connection stability is improved, but transmission efficiency decreases
Solution Approach 1:
The patent segments the data transmission process by using fixed-length Bluetooth data packets (31 bytes each) with structured AD Structures. The therapy data is divided into multiple packets that can be independently transmitted and received, allowing efficient batch broadcasting to multiple devices simultaneously without requiring individual connection handshakes, thereby improving transmission efficiency while maintaining connection stability
3Adaptability or versatility
If fixed-length Bluetooth data packets with invalid data complementation are used, then protocol compatibility is improved, but data transmission efficiency decreases
Solution Approach 1:
The patent changes the data packaging parameters by using fixed 31-byte Bluetooth packets with AD Structure formatting. Each packet includes a data length field, type field, and data field, with invalid data (0x00) used to complement packets when the actual data is shorter than 31 bytes. This parameter standardization ensures compatibility with the Bluetooth protocol while maintaining efficient data transmission through structured packet formatting

AI summary
The disclosure discloses a method and device for sending medical instrument data, and a method and device for receiving medical instrument data. The method for sending the medical instrument data is based on a Bluetooth protocol and includes: starting a Bluetooth module; acquiring therapy data; according to a data packet encapsulation method of a standard Bluetooth protocol, filling a data length of the therapy data into a data length Len segment of a Bluetooth data packet, setting a designated data type and filling the designated data type into a data type AD Type segment, coding the therapy data according to a preset coding rule, and then filling the coded therapy data into a data AD data segment, so that a broadcast data packet is formed; and broadcasting the broadcast data packet according to a preset period in a Bluetooth broadcast mode. According to the disclosure, pairing between a terminal device and a medical instrument does not need to be performed on the medical instrument, so that compared with a conventional medical instrument data transmission scheme, the method and device for sending and receiving the medical instrument data are simple in operation and applicable to various application scenarios.
