Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, and in particular to an encrypted connection system and a cold compress device containing the same. Background Technology

[0002] Cold compress devices are widely used in sports rehabilitation, pain relief, and postoperative care. They achieve targeted cooling therapy through the circulation and conduction of cooled liquid. Cold compress devices typically consist of a main unit and application accessories. The main unit, as the control and power core, is responsible for cooling, driving liquid circulation, and adjusting treatment parameters. Application accessories include protective gear for the head, face, shoulders, waist, arms, and legs, which serve as treatment execution components and directly contact the body to achieve cooling conduction.

[0003] In existing cold compress devices, there is no effective authentication or encrypted communication mechanism between the main unit and application accessories. This allows unauthorized protective gear to be freely connected to the main unit and activated, leading to the following problems: First, unauthorized application accessories may cause temperatures to deviate from safe ranges due to material incompatibility (e.g., thermal conductive materials not meeting medical standards) or mismatched temperature conduction parameters (e.g., heat dissipation efficiency not matching the main unit's cooling power). This can result in reduced treatment effectiveness or even frostbite and other safety accidents for users. Second, the disorderly compatibility of third-party application accessories and their direct replacement of original manufacturer's dedicated application accessories will erode the original manufacturer's consumables market, affecting the manufacturer's R&D investment recovery and the sustainability of its business model. Third, the connection of unauthorized application accessories will introduce non-standard treatment parameters, leading to distorted data collection. Furthermore, the mixing of unauthorized application accessory usage records with original manufacturer data will cause data pollution, rendering data-based efficacy evaluation, user health analysis, and equipment optimization unreliable.

[0049] Example 1

[0050] Please see Figure 1 As shown, an embodiment of this utility model discloses an encrypted connection system 1 for establishing an encrypted connection mechanism between a host 22 and an application accessory 21, fundamentally solving the problems of medical risks, commercial infringement, and data interference inherent in existing cold compress devices 2. The encrypted connection system 1 includes an accessory module 11, a host module 12, and a processing module 13. The accessory module 11 is installed on the application accessory 21 and stores an ID number and a first password. The processing module 13 is connected to the accessory module 11 and reads and stores the ID number and the first password. The host module 12 is installed on the host 22 and connected to the processing module 13. It reads and identifies the ID number and calculates a second password, and reads the first password and compares it with the second password.

[0051] It is understood that the encrypted connection system 1 provided in this embodiment of the present invention, by constructing an architecture in which the accessory module 11 stores the ID number and the first password, the processing module 13 receives and stores the ID number and the first password, and the host module 12 reads the ID number and generates a second password and compares the first password with the second password for encryption, realizes dual authentication of the identity recognition and password verification between the application accessory 21 and the host 22, effectively prevents unauthorized accessories from accessing and using the device, and solves the problems of medical risks, commercial infringement and data interference caused by the lack of a security authentication mechanism between the host 22 and the application accessory 21 in the existing cold compress device 2.

[0052] Specifically, the accessory module 11 is located on the application accessory 21 of the cold compress device 2, and the accessory module 11 stores an unmodifiable unique ID number and a first password; wherein, the unique ID number is a chip-level identifier exclusive to each protective gear, and the first password is a key generated by an encryption algorithm that is consistent with the preset algorithm of the host module 12 through the unique ID number input before the protective gear leaves the factory.

[0053] More specifically, the application accessory 21 can be selected as protective gear for the head, face, shoulders, waist, arms, legs, etc., but should not be construed as a limitation of this utility model.

[0054] More specifically, in this embodiment of the invention, the unique ID number is a 20-bit digital identifier, and the first password is a 6-bit digital key obtained by performing a pairwise XOR operation on the four values ​​of the ID number.

[0055] Specifically, the host module 12 is integrated into the host 22 of the cold compress device 2. It is used to read the unique ID number stored in the processing module 13 through a preset signal transmission channel and verify the ID's legality. The host module 12 also has a built-in encryption algorithm unit 1241 and a comparison unit 1242. After the ID number is verified to be legal, the encryption algorithm unit 1241 performs real-time calculations on the read ID number to generate a second password, and the comparison unit 1242 compares and matches the second password with the first password. If the comparison result is correct, the host module 12 controls the cold compress device 2 to start the treatment function; if the comparison result is incorrect, the host module 12 refuses to start the treatment.

[0056] More specifically, the host module 12 can verify the legality of the ID by the following methods: first, comparing it with the list of legal IDs pre-stored in the host 22; second, verifying whether the number of digits of the ID number conforms to the preset 20-digit identifier.

[0057] Specifically, the processing module 13 establishes physical connections and data interaction channels with the host module 12 and the accessory module 11 respectively. The processing module 13 has a built-in password storage and comparison unit 1242 and a password reading unit 13222. The password reading unit 13222 is used to read the ID number and the first password stored in the accessory module 11 through the data reading channel. The password storage unit 13221 is used to receive and temporarily store the ID number and the first password.

[0058] Furthermore, please combine Figures 1 to 3 As shown, the processing module 13 includes an encrypted pipeline component 131 and a conversion processing component 132. The encrypted pipeline component 131 is connected to the host module 12 and the conversion processing component 132 respectively. The conversion processing component 132 is connected to the encrypted pipeline component 131 and the accessory module 11 respectively. The conversion processing component 132 is used to read and store the ID number and the first password.

[0059] Specifically, the encrypted pipeline assembly 131 not only serves as the cooling liquid circulation channel and inflation channel of the cold compress device 2, realizing the conduction of cooling liquid between the main unit 22 and the application accessory 21 and the inflation of the protective gear; it also serves as the carrier for signal and power transmission, and can be detachably connected to the main unit module 12 and the conversion processing assembly 132 respectively.

[0060] Specifically, the conversion processing component 132 is connected to the encrypted pipeline component 131 and the accessory module 11 respectively; the conversion processing component 132 has a built-in password storage unit 13221 and password reading unit 13222. The password reading unit 13222 reads the stored ID number and first password through the docking of the accessory module 11. The password storage unit 13221 is used to store the ID number and the first password comparison unit 1242.

[0061] Furthermore, please combine Figure 2 and Figure 3 As shown, the conversion processing component 132 includes a first connector 1321 and a circuit board 1322. The circuit board 1322 is disposed on the first connector 1321. The first connector 1321 is connected to the encrypted pipeline component 131 and the accessory module 11 respectively. The circuit board 1322 is used to read and store the ID number and the first password.

[0062] Specifically, the first connector 1321 is an adapter connector between the pipe and the fitting module 11. Its structure and the connector of the fitting module 11 form a male and female connector assembly, which can be detachably connected to the protective connection end of the encrypted pipe assembly 131 and the fitting module 11 respectively. The first connector 1321 has a reserved installation position inside, and the circuit board 1322 is fixedly embedded in the installation position. The circuit board 1322 is electrically connected to the encrypted pipe assembly 131 through wires.

[0063] Specifically, the circuit board 1322 integrates a power supply interface, a data transceiver interface, a data read interface, and a password storage chip. The power supply interface receives power from the host module 12 to maintain operation. The data read interface is activated after docking with the accessory module 11 and reads the ID number and first password of the accessory module 11. The password storage chip stores the read ID number and first password, and the data transceiver interface sends the ID number and first password to the host module 12.

[0064] Further, please refer to Figure 6 As shown, the circuit board 1322 includes a password reading unit 13222 and a password storage unit 13221; the password reading unit 13222 is used to read the ID number and the first password stored in the accessory module; the password storage unit 13221 is used to receive and store the ID number and the first password.

[0065] Specifically, by configuring the circuit board 1322 as a password reading unit 13222 that reads the ID number and the first password stored in the accessory module, and a password storage unit 13221 that receives and stores the ID number and the first password, the system achieves accurate reading and secure storage of the ID number and the first password, dynamic password generation based on the ID number to avoid the risk of static password leakage, efficient password comparison and verification, and targeted control of the number of times protective gear is used. At the same time, it improves the accuracy and security of the encryption verification process, prevents unauthorized protective gear from accessing the system by imitating static passwords, and supports the sustainable operation of the subscription system for supporting equipment and consumables.

[0066] Furthermore, the encrypted conduit assembly 131 includes an encrypted conduit 1311 and a power signal line 1312. The power signal line 1312 is embedded in the wall of the encrypted conduit 1311. The encrypted conduit 1311 is connected to the host 22 and the first connector 1321 respectively. The power signal line 1312 is electrically connected to the host module 12 and the circuit board 1322 respectively.

[0067] Specifically, the encrypted pipe 1311 is made of medical-grade low-temperature resistant and anti-aging material, which can be modified PVC. The two ends of the encrypted pipe 1311 are a protective gear connection end and a main unit connection end, respectively. The protective gear connection end is connected to the first connector 1321, and the main unit connection end is connected to the main unit 22. The inside of the pipe is a hollow structure and is used to realize the circulation of refrigerant liquid between the main unit 22 and the application accessory 21, as well as the inflation of the application accessory 21 by the main unit 22.

[0068] Specifically, one end of the power signal line 1312 extends to the protective connection end of the encrypted conduit 1311 and is soldered and fixed to the circuit board 1322 inside the first connector 1321; the other end extends to the host connection end of the encrypted conduit 1311 for establishing an electrical connection with the host module 12; the encrypted conduit assembly 131, through the power signal line 1312, simultaneously realizes the power transmission from the host module 12 to the circuit board 1322 and the data interaction between the host module 12 and the circuit board 1322.

[0069] More specifically, the metal power signal line 1312 is embedded inside the wall of the encrypted conduit 1311 to avoid contact with the cooling liquid. The wire material can be gold-plated copper wire, which can ensure low resistance, high corrosion resistance and signal transmission stability.

[0070] Furthermore, the accessory module 11 includes a second connector 111 and a label 112. The label 112 is disposed on the second connector 111. The second connector 111 is connected to the first connector 1321 and the application accessory 21 respectively. The label 112 is used to store the ID number and the first password.

[0071] Specifically, the second connector 111 is a dedicated docking component for the application accessory 21. Its structure is adapted to the first connector 1321 to form a male and female connector assembly. One end of the second connector 111 is fixedly connected to the interface of the application accessory 21, and the other end can be detachably docked with the first connector 1321. After docking, the encrypted pipe 1311 can be connected to the refrigerant liquid or gas filling channel of the application accessory 21, and at the same time, the data interaction between the tag 112 of the accessory module 11 and the circuit board 1322 is activated.

[0072] More specifically, the tag 112 is a passive or active tag with a built-in encryption chip, optionally an NFC tag. The tag 112 is fixedly embedded in a preset position inside the second connector 111. The chip of the tag 112 stores an ID number and a first password. The ID number is a unique ID number that cannot be modified, and the ID number corresponding to each protective gear is unique. For example, it can be in the format of 4 bytes FE997A44. The first password is a 6-byte key generated by the host 22 using the ID number of the protective gear through a pairwise XOR encryption algorithm before the protective gear leaves the factory. For example, it can be in the format of 67E33EBA84DD.

[0073] Furthermore, please combine Figure 1 and Figure 4 As shown, the host module 12 is an execution unit for encryption verification, including a third connector 121 and a main control board 124. The main control board 124 is located inside the host 22. The third connector 121 is connected to the host 22 and the encryption pipe 1311 respectively. The power signal line 1312 passes through the interior of the third connector 121 and protrudes to form a protrusion. The protrusion is electrically connected to the main control board 124.

[0074] Specifically, the main control board 124 integrates a password comparison chip, which is used to logically compare the first password with the second password to generate a correct or incorrect verification result. The correct verification result corresponds to a high-level signal, and the incorrect verification result corresponds to a low-level signal. The main control board 124 then determines whether to start treatment based on the signal.

[0075] Specifically, the third connector 121 is an adapter connector between the encrypted conduit 1311 and the host 22, and is fixedly installed at the host connection end of the encrypted conduit 1311. The third connector 121 has a wire through hole inside. After the metal power signal line 1312 embedded in the encrypted conduit 1311 passes through the through hole, its end point protrudes on the mating surface of the third connector 121 to form a protrusion, which is a metal contact.

[0076] More specifically, the interface between the third connector 121 and the host 22 is detachably connected. After connection, the protruding part contacts the conductive component at the interface of the host 22. In this embodiment of the present invention, the conductive component is the pin 123 of the fourth connector 122, so as to realize the electrical connection between the circuit board 1322 and the main control board 124, and provide a path for subsequent power supply and data transmission.

[0077] Further, please refer to Figure 6As shown, the main control board 124 includes an encryption algorithm unit 1241, a comparison unit 1242, and a counting unit 1243; the encryption algorithm unit 1241 is used to perform real-time calculations on the read ID number to generate the second password; the comparison unit 1242 is used to compare and match the first password and the second password; the counting unit 1243 is used to record the number of times each ID number is used.

[0078] Specifically, the main control board 124 is configured to include an encryption algorithm unit 1241 that performs real-time calculations on the read ID number to generate a second password, a comparison unit 1242 that compares and matches the first password with the second password, and a counting unit 1243 that records the number of times each ID number is used. This enables accurate reading and secure storage of the ID number and the first password, dynamic password generation based on the ID number to avoid the risk of static password leakage, efficient password comparison and verification, and targeted control of the number of times protective gear is used. At the same time, it improves the accuracy and security of the encryption verification process, prevents unauthorized protective gear from accessing the system by imitating static passwords, and supports the sustainable operation of the subscription system for equipment and consumables.

[0079] Furthermore, please combine Figure 1 and Figure 5 As shown, the host module 12 also includes a fourth connector 122 and a dotting pin 123. The dotting pin 123 is disposed on the fourth connector 122. The fourth connector 122 is connected to the host 22 and the third connector 121 respectively. The main control board 124 is electrically connected to the protruding part through the dotting pin 123.

[0080] Specifically, the fourth connector 122 is an interface component fixedly installed on the host 22. Its structure is adapted to the third connector 121 to form a male and female connector assembly. The outer surface of the fourth connector 122 is marked with a corresponding mark to the third connector 121 to ensure the correct docking direction.

[0081] Specifically, the dotting pin 123 is a metal conductive pin, which can be gold-plated copper pin, and is fixedly embedded inside the fourth connector 122. Its number is the same as the number of metal power signal lines 1312. When the third connector 121 and the fourth connector 122 are connected, one end of the dotting pin 123 is in close contact with the protrusion of the third connector 121, and the other end is electrically connected to the main control board 124 through the wire inside the host 22, thus forming a power supply circuit and a data communication circuit between the main control board 124, the dotting pin 123, the protrusion, the power signal lines 1312, and the circuit board 1322.

[0082] Furthermore, please combine Figure 4 and Figure 5As shown, the power signal line 1312 includes a power line 13121 and a signal line 13122. Both the power line 13121 and the signal line 13122 are embedded in the wall of the encrypted conduit 1311. Both the power line 13121 and the signal line 13122 are electrically connected to the main control board 124 and the circuit board 1322. The power line 13121 is used to supply power to the circuit board 1322, and the signal line 13122 is used to transmit signals between the main control board 124 and the circuit board 1322.

[0083] Specifically, the power cord 13121 includes two metal wires, namely a positive wire and a negative wire. One end of each wire is soldered to the power supply interface of the circuit board 1322, and the protruding part of the other end is respectively in contact with the pin 123 of the fourth connector 122, thereby electrically connecting to the main control board 124. This enables the main control board 124 to provide a stable operating voltage to the circuit board 1322, ensuring the password reading and storage of the circuit board 1322.

[0084] Specifically, signal line 13122 includes at least one metal wire. More specifically, it can be optionally configured as two wires, namely a transmitting wire and a receiving wire, or it can be optionally configured as a single multiplexed wire. Taking two wires as an example, the two wires are a transmitting wire and a receiving wire. One end of the transmitting wire is connected to the signal transmitting end of the main control board 124, and the other end is connected to the signal receiving end of the circuit board 1322. It is used to transmit signals sent by the main control board 124, such as password reading commands. One end of the receiving wire is connected to the signal transmitting end of the circuit board 1322, and the other end is connected to the receiving end of the main control board 124. It is used to transmit signals fed back by the circuit board 1322, such as the unique ID number of the protective gear and the first password.

[0085] For example, the signal line 13122 adopts a differential transmission design, which can further reduce the impact of external interference on signal transmission. The metal wires are all gold-plated copper wires, which can ensure the signal transmission rate and stability.

[0086] Example 2

[0087] The second embodiment of this utility model discloses a cold compress device 2. Please refer to [link / reference]. Figure 7 As shown, the cold compress device 2 includes an application accessory 21, a host 22, and an encrypted connection system 1 as described in Embodiment 1. The encrypted connection system 1 connects the host 22 and the application accessory 21 respectively, and is used to match and compare the application accessory 21 and the host 22.

[0088] Specifically, the application accessory 21 is a cold compress protective gear, including knee joint braces, elbow joint braces, etc., which has a cooling liquid flow channel and an inflation chamber inside, used to cooperate with the main unit 22 to achieve targeted cooling treatment; the main unit 22 is the core control unit of the cold compress device 2, which has a built-in cooling module, a liquid circulation pump and an inflation pump. The cooling module, the liquid circulation pump and the inflation pump are all electrically connected to the main control board 124 of the main unit module 12. The main control board 124 controls the opening or closing of the cooling module, the liquid circulation pump and the inflation pump to generate cooling liquid and drive its circulation, while inflating the protective gear to ensure that the protective gear fits the human body.

[0089] Specifically, please combine Figure 7 And the example provided in Example 1 Figures 1 to 6 As shown, the encrypted connection system 1 is detachably connected to the host 22 via the fourth connector 122 and to the application accessory 21 via the second connector 111, and is used to achieve dual authentication matching between the host 22 and the protective gear. The matching steps are as follows: First, the processing module 13 reads and stores the ID number and the first password of the application accessory 21; second, the host module 12 reads the ID number and verifies its legality, and calculates the second password; third, the host module 12 reads the first password and compares it with the second password; fourth, if the matching result is correct, the host module 12 controls the opening of the cooling module, the liquid circulation pump and / or the air pump. At the same time, the main control board 124 of the host 22 is also equipped with a counting unit 1243 to record the number of times each protective gear ID number is used. Each complete treatment cycle is counted as 1 use. When the number of uses reaches the host 22's preset upper limit value, which can be selected as 50 uses, the encrypted connection system 1 will reject the subsequent matching of the protective gear and prohibit the host 22 from starting treatment, so as to realize the subscription sales model of equipment and consumables.

[0090] Furthermore, the encrypted connection system 1 includes an accessory module 11, a host module 12, and a processing module 13. The accessory module 11 is located on the application accessory 21 and stores the ID number and the first password. The host module 12 is located on the host 22. The processing module 13 is connected to the host module 12 and the accessory module 11 respectively. The processing module 13 is used to read and store the ID number and the first password. The host module 12 is used to read and identify the ID number and calculate the second password. The host module 12 is also used to read the first password and compare and match it with the second password.

[0091] Specifically, the accessory module 11 includes a tag 112, which stores a unique ID number and a first password. Data reading access is only granted after the tag 112 is connected to the first connector 1321 of the processing module 13.

[0092] Specifically, the main control board 124 of the host module 12 sends an ID and first password reading instruction to the processing module 13 via signal line 13122, and receives the unique ID number and first password of the accessory module 11 from the circuit board 1322 of the processing module 13 via signal line 13122; the encryption algorithm unit 1241 of the host module 12 generates a second password based on the read ID number through pairwise XOR operation, and compares and matches it with the first password.

[0093] Specifically, after receiving and successfully recognizing the ID number, the main control board 124 of the host module 12 generates a second password and then reads the first password from the circuit board 1322 of the processing module 13. The first password and the second password are compared byte by byte. If the comparison is consistent, the main control board 124 of the host module 12 receives a "correct" signal. The main control board 124 controls the host 22 to start the cooling, liquid circulation and inflation functions. At the same time, the counting unit 1243 records the number of times the protective gear is used. If the comparison is inconsistent, or the ID number fails the legality verification, the main control board 124 of the host module 12 receives an "error" signal. The host module 12 immediately triggers an alarm, such as flashing LED lights, and controls the host 22 to enter a locked state. The host 22 needs to be unlocked by contacting the manufacturer through a special command and will refuse to start the treatment function.

[0094] The function of the cold compress device 2 provided in the second embodiment of this utility model is the same as that of the encrypted connection system 1 provided in the first embodiment, and will not be repeated here.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
