The working principle of the temperature controller of the multi-functional injection device according to the embodiment of the present invention is described in detail below.
In the case where injection control module 20 is coupled to injection module 10, a warning signal may be generated if the temperature sensed by temperature sensor 231 is not within a predetermined temperature range. In addition, in the event that injection control assembly 20 is not coupled to injection assembly 10, temperature sensor 231 does not measure a temperature within another specified range, which may still trigger timer 232 to operate or disable injection button 26.
Specifically, as shown in fig. 4 and 5, the 1 st set temperature range value associated with the liquid medicine is set, for example, to less than 30 ℃, and the corresponding set time period value is set, for example, to 3 hours, and these data are recorded in the recording medium controller. In addition, the 2 nd set temperature range value associated with the liquid medicine, for example, less than 60 ℃, and the corresponding set time period value, for example, 0.1 second, are also recorded in the recording medium controller. The anti-misuse portion includes a liquid crystal display device 60 for alerting the user that the injection assembly 10 is not usable. Thus, if processor 27 receives the signal when the temperature sensed by temperature sensor 231 exceeds 30℃, processor 27 starts timer 232 and when the time recorded by timer 232 exceeds 3 hours, processor 27 controls the display device to display a warning that injection assembly 10 is not usable.
In addition, if the other timer 232 is started when the temperature sensed by the temperature sensor 231 exceeds 60 ℃, the processor 27 controls the liquid crystal display device 60 to issue a corresponding warning when the time recorded by the other timer 232 exceeds 0.1 second. That is, when the temperature sensed by the temperature sensor 231 exceeds 60 ℃, the processor 27 issues the instruction substantially immediately. While the warning is displayed on the liquid crystal display device 60, the processor 27 issues another command to disable the power supply to the injection motor 27 so that the injection assembly 10 is in an inoperable state.
The syringe 12 is mounted to contact the detection switch 30. the detection switch 30 is mounted to the detection switch 30 at the first connection portion and/or the second connection portion, and is controlled by the processor 27 such that the detection switch 30 is turned on when the syringe 12 is mounted. The processor 27 receives a corresponding signal and determines that the syringe 12 is now mounted. The timer 2321 can be started immediately as soon as the measured temperature exceeds the 1 st set temperature range.
When injector 12 is removed from injection control assembly 20, and injection assembly 10 with injector 12 removed is in the on-stream condition (during which time detection switch 30 is open), timer 232 will not be started as long as the temperature of injection assembly 10 does not exceed the 2 nd set temperature range. When a warning is issued by a display device such as the liquid crystal display device 60, the user needs to remove the syringe 12 from the second housing 21 in accordance with the warning. The detection switch 30 mounted on the second housing 21 is turned off to remove the syringe 12, and the processor 27 receives a corresponding signal to determine that the syringe 12 has been removed from the second housing 21.
The processor 27 also includes an alert release portion having an alert release button 40. In a state where the processor 27 judges that the syringe 12 has been removed from the second housing 21, the warning release button 40 is pressed, the warning indication disappears, and the instruction to prohibit the supply of power to the injection motor 27 is released. If the injector 12 is not removed from the second housing 21, the warning lock is not released even if the warning release button 40 is pressed, and the instruction to prohibit the power supply to the injection motor 27 cannot be released. In this way, it is possible to prevent the occurrence of an injection without replacing the syringe 12. When the injection assembly 10 is activated and a new syringe 12 is loaded into the second housing 21, the central processing unit determines that the syringe 12 is loaded and the timer 232 enters a standby state. Prior to injection, a double ended needle is inserted into the forward end of the injector 12 and the injection needle penetrates the user's body. Subsequently, the injection button 26 connected to the processor 27 is pressed, the processor 27 drives the injection motor 27 to operate, and the movable rod 29 linked therewith is pushed forward. The foremost end of the movable rod 29 contacts the back surface of the gasket and is pushed forward with a certain push. Finally, the gasket inside the syringe 12 moves a corresponding amount of the medical fluid, which is injected into the body of the user through the needle. The amount of drug and the program for operating the injection assembly 10 are stored in the recording medium controller of the injection assembly 10 each time, and by pressing the injection button 26, the central processing unit runs the program recorded in the recording medium controller, and 1 dose of the drug solution is pushed out of the syringe 12 through the injection needle. After the injection of the medical solution, the injection needle is removed, the syringe 12 is removed from the second housing 21, and the syringe 12 is stored in a refrigerator before the next use. The syringe assembly 10 is stored at room temperature. For the next use, the syringe 12 is reinstalled on the second housing 21 of the injection assembly 10.
According to the utility model discloses multi-functional syringe 12, through installation temperature controller, dosage display 24, dosage regulator 25 and treater 27 in second shell 21, treater 27 forbids injection button 26 when temperature controller and/or dosage display 24 send warning signal, and this multi-functional syringe 12 can avoid the user to use the liquid medicine that became invalid, and the user of also being convenient for simultaneously realizes accurate dose injection, prolongs multi-functional injection device's life.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
