[0058] Example 2

[0059] This embodiment 2 provides an infusion detection device, including any infusion detection circuit in the above-mentioned embodiment 1.

[0060] The device further comprises a housing 9, wherein the infusion detection circuit is partially located inside the housing 9 and partially exposed outside the housing 9. For example, in some specific embodiments, the connection contacts 121 in the external charging component 12 and the keys connected to the key circuit 8 are exposed on the outer surface of the housing 9. Figure 5 As shown, in a specific embodiment, the infusion detection device obtains electrical energy from the outside through the bidirectional wireless charging coil 15 in its circuit, and is charged in a non-contact manner. The infusion detection device is connected to the external device through the connection contacts on the outer surface of the shell 9, and the external device is charged in a contact manner.

At this time, the main control module 2 can control the connection and disconnection between the external charging component 12 and the charging chip 16 according to the power status of the device obtained from the power management module 13.

[0061] In a specific use process of the infusion detection device, the battery 11 in the infusion detection circuit can first obtain electrical energy from an external charging device through a bidirectional wireless charging coil 15 via a charging chip 16, and then further power other components such as the main control module 2, the weight detection component 3, and thermistor 6 in the detection circuit. The weight detection component 3 is further connected to the external infusion device through a connecting mechanism 31, obtains the weight change data of the infusion liquid from the external infusion device and uploads it to the main control module 2. When the main control module 2 obtains the weight change of the infusion liquid, it further uploads this message to the external platform through the short-distance communication component 21. The external platform is managed by medical staff, and the staff can make notes and presets in advance on the infusion time of each external infusion device, the type of medicine of the infusion liquid, etc. through the external platform. When the main control module 2 detects that the infusion liquid in the external infusion device is about to run out or has been exhausted, it sends a warning message to the external platform to prompt the medical staff to deal with it immediately. It can effectively save the patrol time of medical staff and improve the efficiency of nursing.

[0062] While the main control module 2 sends a warning message to the external platform, the prompt module in the detection circuit will also work at the same time. The prompt module can be a prompt alarm device that can emit light, vibration or buzzer. By emitting light, sound, and / or vibration alarms, the device can not only prompt the remote medical staff, but also the patient who is currently receiving an infusion and the medical staff on site, thereby further improving the degree of cooperation between medical staff.

[0063] In an actual application process, in addition to detecting the weight change of the infusion liquid through the weight detection component 3 and uploading it to the main control module 2, it also includes a thermistor 6 that can sense temperature changes. By connecting the infusion device, it detects the temperature change of the infusion liquid and uploads the temperature change to the main control module 2. When the main control module 2 analyzes and finds abnormal changes, it further reports to the external platform; it also includes an acceleration sensor 5. The acceleration sensor 5 senses the acceleration of the infusion device, such as shaking, and uploads the acceleration data to the main control module 2. When the main control module 2 analyzes and finds abnormal conditions such as the imbalance of the infusion device, it can further report to the external platform. This allows medical staff to remotely pay attention to more types of abnormal conditions, and can more comprehensively ensure the safety of patients during the infusion process.

[0064] In an actual use process, the infusion detection device can further interact with other external devices such as infusion auxiliary devices, and perform contact charging of the external device through the external charging component 12 in the infusion detection circuit, or perform contactless charging of the external device through the bidirectional wireless charging coil 15. Such a design allows the infusion detection device to be used in conjunction with other auxiliary devices for infusion, which can further improve the intelligence of infusion detection.

[0065] When the external device is connected to the infusion detection device via the connection contacts, and the infusion detection device itself is charged contactlessly with the external charging device, the main control module 2 sets the level of the control pin on the corresponding connection contact, so that the external charging device can charge the external device and the battery 11 inside the infusion detection device alternately.

[0066] The battery 11 is connected to a power management module 13, which can monitor the current power consumption in real time and reflect the power status through the power indicator component 14. Among them, the power indicator component 14 can be an indicator light or an indicator screen. The detection circuit also includes a key circuit 8 and a key connected to the key circuit 8. The user can turn on or off the main control module 2 by pressing or toggling the key 81, and can also turn on or off the external charging function of the detection device, that is, control the connection between the external charging component 12 and the charging chip 16. It should be noted that this embodiment does not limit the specific number of keys 81, and there can be multiple keys, which are used to control the switch of the main control module and the switch of the external charging function.

[0067] When the infusion detection device is charging an external device, the power management module 13 will manage the remaining power of the battery 11 for the detection device's own operation and the power distribution of the detection device for charging external devices. In the main control module 2, a power warning value can be preset in the power management module 13 in advance. When the power management module 13 detects that the remaining power in the battery 11 is lower than the power warning value, the connection between the external charging component 12 and the charging chip 16 is disconnected, and the charging of the external device is stopped. The remaining power is used for its own operation. This allows the detection device to still maintain its own operation priority during use, and can prioritize the normal operation of the main function when the power is low.

[0068] In actual applications, the external platform can realize real-time monitoring of the weight data of the infusion liquid in the external infusion device. One external platform can correspond to multiple infusion detection devices and monitor the consumption of the infusion liquid in multiple infusion devices in real time. The staff can understand the consumption of the infusion liquid in each infusion device through the external platform in real time. When the infusion is about to be completed, the medical staff can receive feedback in time and carry out follow-up nursing work, which can effectively reduce the workload of medical staff in monitoring the patient during the infusion process.

[0069] This embodiment provides an infusion detection device, which acquires the weight data of the infusion liquid in the external infusion device by setting a weight detection component and uploads it to an external platform, so that the staff can remotely manage the infusion status of the patient on the external platform, which can effectively reduce the workload of medical staff and improve work efficiency. At the same time, the power module in the detection device can perform intelligently controlled wired or wireless charging for external devices, which can broaden the use scenarios of the infusion detection device.

[0070] The above is a specific description of the preferred implementation of the present application, but the invention of the present application is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent modifications or substitutions without violating the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
