Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field related to insulin pump, in particular to a temperature monitoring system and method. BACKGROUND

[0002] Insulin pump is a portable medical device for insulin injection. The insulin injected by the insulin pump during operation has different storage temperatures according to different types. Generally, it can be maintained for about 28 days when the temperature is not more than 30 degrees Celsius. When the temperature is lower than 0 degrees Celsius, the activity of insulin will be destroyed. When the temperature is higher than 30 degrees Celsius, the activity of insulin will be reduced. Under high temperature conditions, insulin preparations are easy to decompose and lose effectiveness.

[0003] At present, the existing insulin pump does not install a temperature monitoring module, so it cannot monitor the temperature of the insulin in the insulin pump. When the patient uses the insulin pump for insulin injection, the insulin may be inactivated or at risk of inactivation due to the temperature exceeding the range, so that the patient injects ineffective insulin and cannot achieve the expected blood sugar lowering effect, which will have a great impact on the patient's body.

The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0047] As Figure 1 , Figure 4As shown, the temperature monitoring system 100 provided by an embodiment of the present application comprises a liquid storage device 10, a piston 20, a push rod 30 and a signal transmission module.

[0048] The liquid storage device 10 is used for containing insulin (not shown in the figure), and the piston 20 is movably installed in the liquid storage device 10. The piston 20 is provided with a temperature sensor 101, which is used for detecting the temperature of the insulin in the liquid storage device 10. The push rod 30 can push the piston 20, so that the piston 20 extrudes the insulin in the liquid storage device 10 and discharges the insulin from the liquid storage device 10, that is, when the temperature monitoring system 100 works, the control of discharging the insulin from the liquid storage device 10 can be realized by controlling the push rod 30 to push the piston 20. It should be noted that the temperature monitoring system 100 is specifically applied to an insulin pump (not shown in the figure), and the driving of the push rod 30 can be manually driven or realized by using a telescopic motor or other telescopic driving member, which will not be described here.

[0049] In the present application, the signal transmission module is installed on the piston 20 and / or the push rod 30, and the signal transmission module can be signal-connected with the temperature sensor 101 under the driving of the piston 20 and / or the push rod 30, so that the temperature data measured by the temperature sensor 101 can be transmitted to the signal transmission module. It should be noted that the signal transmission module of the present application is specifically arranged on the piston 20 and the push rod 30.

[0050] The signal transmission module comprises a temperature sensor circuit (not shown in the figure) and a signal receiving circuit (not shown in the figure). The temperature sensor circuit is installed in the piston 20 and electrically connected with the temperature sensor 101. The signal receiving circuit is installed in the push rod 30 and can receive the temperature data measured by the temperature sensor 101. When the temperature monitoring system 100 of the present application works, whether the temperature sensor circuit and the signal receiving circuit are powered on can be used to control whether the temperature data measured by the temperature sensor is transmitted. It should be noted that the main power source for supplying power to the temperature sensor circuit and the signal receiving circuit in the temperature monitoring system 100 of the present application can be arranged in the push rod 30, which will not be described here.

[0051] As Figure 2As shown, in an embodiment, the piston 20 of the embodiment is provided with a first connecting contact 41, and the push rod 30 is provided with a second connecting contact 42 matched with the first connecting contact 41; and the push rod 30 can drive the second connecting contact 42 to contact the first connecting contact 41, so as to power on and work the temperature sensor circuit and the signal receiving circuit. In this way, the embodiment of the temperature monitoring system 100 working time, the temperature sensor circuit and the signal receiving circuit whether to power on control, so that when the push rod 30 drive the second connecting contact 42 and the first connecting contact 41 contact, the temperature monitoring system 100 only work and transmit the temperature data measured by the temperature sensor 101, and realize the monitoring of the temperature of the insulin in the liquid reservoir, which can reduce the power consumption. It should be noted that the installation position of the first connecting contact 41 on the piston 20, and the installation position of the second connecting contact 42 on the push rod 30, can be specifically set according to the use requirement that the second connecting contact 42 can contact the first connecting contact 41 when the push rod 30 pushes the piston 20, which will not be described here. Of course, the number of the first connecting contact 41 and the second connecting contact 42 is two, and the first connecting contact 41 and the second connecting contact 42 are both set as metal contacts, so that when the first connecting contact 41 and the second connecting contact 42 contact, the temperature sensor circuit and the signal receiving circuit can be powered on and work.

[0052] As can be seen from the above, when the temperature monitoring system 100 of the embodiment works, the temperature data detected and obtained by the temperature sensor 101 can be controlled to be transmitted by specifically cooperating the push rod 30 and the piston 20. It should be noted that the cooperation between the push rod 30 and the piston 20 specifically refers to the cooperation relationship between the push rod 30 and the piston 20 when the push rod 30 pushes the piston 20 to move in the liquid reservoir 10, which will not be described here.

[0053] Specifically, when the push rod 30 pushes the piston 20 to move in the liquid reservoir 10, the temperature sensor 101 can detect the temperature of the insulin in the liquid reservoir 10 and transmit the measured temperature data to the signal transmission module, so as to facilitate the subsequent retransmission and use of the temperature data; and when the push rod 30 is not cooperated with the piston 20, the signal transmission module is disconnected with the temperature sensor 101, which can reduce the running power consumption of the temperature monitoring system 100.

[0054] As Figure 3As shown, in another embodiment, the piston 20 is equipped with a signal transmitter 410, and the push rod 30 is equipped with a signal receiver 420 to match the signal transmitter 410. Through the cooperation between the signal transmitter 410 and the signal receiver 420, the temperature sensor circuit and the signal receiving circuit are energized and operate. This specifically implements another embodiment of controlling whether the temperature sensor circuit and the signal receiving circuit are energized when the temperature monitoring system 100 is working, so that the temperature monitoring system 100 only operates and transmits the temperature data measured by the temperature sensor when the signal transmitter and the signal receiver are in cooperation, thereby monitoring the temperature of insulin in the reservoir. It should be noted that the signal transmitter 410 and the signal receiver 420 in this embodiment can specifically be configured as metal coils, and the two metal coils can be passively connected via NFC contacts to energize and operate the temperature sensor circuit and the signal receiving circuit.

[0055] In one embodiment, the temperature monitoring system 100 further includes a protective film 50 disposed on the side of the piston 20 facing the insulin, used to separate the insulin from the piston 20. This not only protects the temperature sensor 101 on the piston 20 but also prevents contamination of the insulin due to direct contact with the piston 20. It should be noted that the protective film 50 is installed inside the reservoir 10, completely isolating the insulin within the reservoir 10 to prevent insulin from intruding into the location of the piston 20. Alternatively, the temperature sensor 101 can pass through the protective film 50 and directly contact the insulin inside the reservoir 10, or it can be isolated to one side of the protective film 50. Specifically, the protective film 50 can be a heat-conducting element, enabling the temperature sensor 101 to accurately detect the insulin temperature.

[0056] A reservoir connector 11 is connected to the reservoir 10, allowing insulin within the reservoir 10 to be discharged through the reservoir connector 11. This facilitates the connection between the reservoir 10 and the infusion set (not shown) when the temperature monitoring system 100 is used with the insulin pump. Specifically, the reservoir connector 11 can be located at the middle position of the end of the reservoir 10 furthest from the piston 20, allowing insulin within the reservoir 10 to be discharged through the reservoir connector 11 under the pushing force of the piston 20.

[0057] The temperature monitoring system 100 of this application also includes a reservoir 60, in which the reservoir 10 is detachably installed to meet the usage requirements of the temperature monitoring system 100 in an insulin pump.

[0058] In one embodiment, the temperature monitoring system 100 further includes a detection sensor (not shown). The detection sensor can detect whether the liquid reservoir 10 is installed inside the liquid reservoir compartment 60 and generate a feedback signal. This allows the temperature monitoring system 100 to use this signal as a basis to control the signal connection between the temperature sensor 101 and the signal transmission module, thereby reducing the power consumption of the temperature monitoring system 100. It should be noted that the detection sensor in this embodiment can specifically be a through-beam laser sensor, a proximity switch, etc., installed inside the liquid reservoir compartment 60, which will not be elaborated upon here.

[0059] It is understandable that when a signal transmitter 410 is installed on the piston 20 and a signal receiver 420 is installed on the push rod 30, if the aforementioned detection sensor detects that the reservoir 10 is installed in the reservoir compartment 60 and generates a feedback signal, the signal transmitter 410 and the signal receiver 420 cooperate to energize and operate the temperature sensor circuit in the piston 20 and the signal receiving circuit in the push rod 30, and receive the temperature data detected and obtained by the temperature sensor 101. Conversely, if the detection sensor does not detect that the reservoir 10 is installed in the reservoir compartment 60, the signal transmitter 410 will not cooperate with the signal receiver 420, causing the temperature sensor circuit and the signal receiving circuit to be de-energized and stop working. In other words, only when the detection sensor detects that the reservoir 10 is installed in the reservoir compartment 60 will the temperature sensor 101 connect to the signal transmission module and realize the detection of the insulin temperature in the reservoir 10, thereby reducing power consumption.

[0060] Additionally, it should be noted that the push rod 30 of this application also includes a power supply to power the temperature sensor 101 and the signal transmission module, thereby meeting the requirements of the temperature monitoring system 100 for monitoring the insulin temperature within the reservoir 10 during operation. Of course, the aforementioned power supply can be a disposable portable power source or a rechargeable power source, which will not be elaborated upon here.

[0061] like Figure 5 As shown, this application also claims protection for a temperature monitoring method, which includes the following steps:

[0062] A temperature monitoring system 100 is provided, and the temperature monitoring system 100 is configured as described above.

[0063] Acquire the temperature data detected and obtained by temperature sensor 101;

[0064] The acquired temperature data was compared with the reference temperature range for insulin.

[0065] Based on the comparison results, it was determined whether the insulin in reservoir 10 was effective.

[0066] The step of "acquiring the temperature data detected and obtained by the temperature sensor 101" is achieved by controlling the signal connection between the signal transmission module and the temperature sensor 101.

[0067] In summary, the temperature monitoring system and method of this application can detect the temperature of insulin in the reservoir 10, thereby determining whether the insulin in the insulin pump equipped with the temperature monitoring system has been inactivated due to temperature. This allows patients to intuitively judge whether the insulin is effective, ensuring that the insulin selected and injected into the body can lower blood sugar and meet the patient's needs.

[0068] The technical features of the above embodiments can be combined in any way. 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.

[0069] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
