Specifically, as shown in Figure 4 and Figure 5, the 1st set temperature value range relevant to medical fluid, for example be set as being less than
30 DEG C and the corresponding value for setting duration, such as it is set as 3 hours, these data are all recorded in record media controller
In.In addition, the 2nd set temperature value range relevant to medical fluid, is, for example, less than the value of 60 DEG C and corresponding setting duration,
Such as 0.1 second, the setting data of these other devices also will record in record media controller.Use is contained in anti-misuse portion
In the liquid crystal display device 60 for reminding user's injecting assembly 10 unusable.So, if when by temperature sensor 231
When the temperature sensed is more than 30 DEG C, processor 27 will receive the signal, and processor 27 starts timer 232, works as timing
When the time that device 232 records is more than 3 hours, processor 27 controls display device, it is made to show that injecting assembly 10 is unusable
Warning remind.
In addition, if another timer 232 starts when the temperature that temperature sensor 231 senses is more than 60 DEG C, when
When the time of another timer 232 record is more than 0.1 second, processor 27 controls liquid crystal display device 60 and issues corresponding warning
It reminds.That is, substantial processor 27 can issue immediately when the temperature that temperature sensor 231 senses is more than 60 DEG C
Above-metioned instruction.While showing warning on liquid crystal display device 60, processor 27 can also issue another instruction, forbid power supply
It powers for injecting motor 27, therefore injecting assembly 10 would be at the state that can not be injected.
Only in the state that syringe 12 is installed on 10 second housing 21 of injecting assembly, the temperature measured is higher than above-mentioned
When the 1st (or according to setting, adding the 2nd) set temperature range, or under the uninstalled state of syringe 12, inspection
When the temperature measured is higher than above-mentioned 2nd set temperature range, processor 27 just will start timer 232.Therefore, it injects
Syringe 12 is removed from injecting assembly 10 and is put into refrigerating chamber preservation by complete medical fluid, and before the next use, injecting assembly 10
Placement is taken care of at room temperature, and under this state, the temperature of only injecting assembly 10 has been more than the 1st set temperature range, therefore is counted
When device 232 be unable to run.
The syringe 12 of installation can contact detection switch 30, and detection switch 30 is mounted on detection switch 30 and is located at the first connection
It in portion and/or second connecting portion, is controlled it by processor 27, when installing syringe 12, detection switch 30 will
Conducting.Processor 27 will receive corresponding signal, judge that syringe 12 has been installed at this time.As long as the temperature one of measurement
Denier is more than the 1st set temperature range, it will be able to start timer 2321 immediately.
When syringe 12 from injection control assembly 20 on remove, removed the injecting assembly 10 of syringe 12 during keeping
(during this, detection switch 30 is disconnected), as long as the temperature of injecting assembly 10 is no more than the 2nd set temperature range, would not open
Dynamic timer 232.When the display devices such as liquid crystal display device 60 give a warning prompting, user will will infuse according to warning prompt
Emitter 12 is removed from second housing 21.The detection switch 30 installed on second housing 21 disconnects, and removes syringe 12, processor 27
Corresponding signal will be received, judges that syringe 12 is removed from second housing 21 at this time.
Processor 27 further includes warning releasing portion, and alerting in releasing portion has a warning releasing button 40.In processor 27
In the state of judging that syringe 12 is removed from second housing 21, warning releasing button 40 is pressed, warning prompt will disappear,
And release the instruction for forbidding powering for injecting motor 27.If syringe 12 is not removed from second housing 21, warning locking, even if
Pressing the warning warning of releasing button 40 will not be released from, and forbid the instruction powered for injecting motor 27 that can not also be solved
It removes.In this way, the case where being changed without syringe 12 and being injected appearance can be prevented.When injecting assembly 10 starts, outside second
After being packed into new syringe 12 on shell 21, central operation processor makes the judgement for having been charged into syringe 12, and timer 232 enters
Standby mode.Before injection, double-ended needle is inserted into 12 front end of syringe, injection needle is pierced into the internal of user.Then, it presses
The lower injection button 26 connecting with processor 27 drives injecting motor 27 to work, the motion bar 29 interlocked with this by processor 27
It is pushed forward into.The back side of the front end contact gasket of motion bar 29, and released forward with certain pushing.Finally, syringe
The medical fluid of gasket moving distance corresponding amount in 12 enters the internal of user by injection needle injection.In injecting assembly 10
Record media controller in store dose each time and the program for acting injecting assembly 10, by by bet
Button 26, program of the central operation processor log in record media controller are penetrated, the medical fluid of 1 component of degree n n just passes through note
Syringe needle is penetrated to be pushed out from syringe 12.After liquid medicine injection, injection needle is removed, then takes syringe 12 from second housing 21
Under, in the next use before, syringe 12 is placed in refrigerator cold-storage room and is saved.And injecting assembly 10 then needs to place at room temperature
Keeping.Syringe 12 in use, be mounted on the second housing 21 of injecting assembly 10 by next time again.
Multifunctional injector 12 according to an embodiment of the present invention, it is aobvious by installing temperature controller, dosage in second housing 21
Show device 24, metering adjuster 25 and processor 27, processor 27 is when temperature controller and/or dose display 24 send warning signal
Injection button 26 is disabled, which can be avoided user using the medical fluid of failure, while be also convenient for user's realization
Accurate dosage injection, extends the service life of multi-functional injection device.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
It should be regarded as protection scope of the present invention.
