Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
Special instruction: " front end ", " rear end " of the present invention is corresponding with " left end ", " right-hand member " in Fig. 1 respectively.
As shown in Figure 1, 2, 3, a kind of department of pediatrics special nutrient fluid injection device, including equipped with the heating chamber 1 of water, hermetically passing
The injection tube 2 in described heating chamber 1 and the heater 4 being arranged in heating chamber 1 and temperature sensor 3, described heater 4 is
Electrical heating wire, described injection tube 2 includes that cylinder 21, the piston 22 being arranged in described cylinder 21 and one end are with described piston 22 even
Connecing the piston rod 23 that the other end stretches out in outside cylinder 21, cylinder 21 front end is provided with liquid outlet 211, and liquid outlet 211 is used for and stomach tube
Connecting, described liquid outlet 211 is provided with out liquid switch 25, and injection tube 2 all passes through when outwards exporting nutritional solution or draw nutritional solution
Liquid outlet 211, described piston rod 23 is driven by actuating device 5 by servomotor 6 and moves along cylinder 21 axis direction, described in watch
Take motor 6 to be connected with PLC 8 by servo-driver 7, described heater 4 and temperature sensor 3 and PLC 8
Connect.It can be rectilinear movement that piston rod 23 moves along cylinder 21 axis direction, it is also possible in rotary moving, described actuating device 5
Can be the gear & rack structure matched, it is also possible to be the screw-nut structure matched, or the transmission knot of other forms
Structure.Owing to the speed of injection nutritional solution is very slow, therefore the present invention combines this feature and have employed a kind of simple in construction, easy to make
Actuating device 5, concrete structure is as follows:
As shown in Figure 1, 2, piston rod 23 uses mode in rotary moving, is provided with for supporting piston in the rear end of cylinder 21
Bar 23 and the bracer 24 with piston rod 23 threaded engagement, described actuating device 5 includes that coaxial sleeve is located at servomotor 6 and exports
