Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is for to the claimed further instruction that the invention provides.
Description of drawings
Accompanying drawing consists of the part of this description, is used for helping further to understand the present invention.These accompanying drawings illustrate preferred implementation of the present invention, and are used for illustrating principle of the present invention with description, in the accompanying drawing:
Fig. 1 is the sketch map according to the real-time testing agency of the injecting systems of embodiment of the present invention; And
Fig. 2 is the A-A cutaway view of real-time testing agency among Fig. 1.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the real-time testing agency of injecting systems of the present invention comprises: the frame that is made of front mounting plate 7 and rear installing plate 8; Actuating device is arranged on the frame, is used for transmitting the driving force from motor, has the moving component of the syringe 9 that promotes injecting systems; And condition checkout gear, be arranged on and state on the frame, change in resistance occurs in response to the change in location of moving component, detect the engagement of actuating device and the injection volume of syringe 9 by change in resistance.
Wherein, frame comprises front mounting plate 7 and rear installing plate 8, and condition checkout gear is specially sliding type rheostat 4, and the two ends of sliding type rheostat 4 are separately fixed on front mounting plate 7 and the rear installing plate 8.
As shown in Figure 2, sliding type rheostat 4 comprises: main body 42; Its two ends are separately fixed on front mounting plate 7 and the rear installing plate 8; Slide plate 41 can slide with respect to main body 42; And circuit board 43, be converted into the variation of magnitude of voltage for the change in resistance that will slide type rheostat 4.
Wherein, the bottom of main body 42 has opening 421 along the longitudinal direction, slide plate 41 be contained in the main body 42 and can be in main body 42 relative sliding, and slide plate 41 has the opening 421 of main body of passing 42 and the teat 411 that stretches out downwards.
As shown in Figure 1, actuating device comprises: leading screw 3, and it is rotated by driven by motor, and the two ends of leading screw 3 are separately positioned on front mounting plate 7 and the rear installing plate 8; Screw 6 is with leading screw 3 engagements, as the moving component of pushing syringe 9; Retainer 5 is fixed together with screw 6, and leading screw 3 can be arranged in the retainer 5; And power transmission shaft 2, an end of power transmission shaft 2 and retainer 5 are fixing, are fixed with termination 1 on the sleeve pipe of the other end, and termination 1 is resisted against on the syringe 9, and the plunger of pushing syringe 9 is injected.
As shown in Figure 2, the top of retainer 5 has groove 51, and the teat 411 of the slide plate 41 of sliding type rheostat 4 is arranged in the groove 51, therefore, drives slide plate 41 relative sliding in main body 42 by retainer 5.
The real-time testing agency of injecting systems of the present invention further comprises central control unit and the alarm device (not shown) that connects with sliding type rheostat 4.The change in resistance of sliding type rheostat 4, be converted into the variation of magnitude of voltage through circuit board 43 after, pass to central control unit, controlled the running of motor by central control unit.Alarm device leading screw 3 and screw 6 engagement appears when unusual or syringe 9 arrive predetermined near-space and during empty position to medical personnel or patient's warning.
The operation principle of the real-time testing agency of injecting systems of the present invention is described below in conjunction with accompanying drawing.
Motor rotation, drive leading screw 3 rotations, the screw 6 that is engaged with is converted into rectilinear motion with rotatablely moving of leading screw 3, screw 6 drives the retainer 5 that is fixed together with it and moves, and then retainer 5 drive power transmission shafts 2 move, the plunger of termination 1 pushing syringe 9 of power transmission shaft 2 other ends carries out normal injection.Simultaneously, when retainer 5 moves, owing to be provided with the teat 411 of slide plate 41 in the groove 51 of retainer 5, thus promote slide plate 41 relative sliding in main body 42 of sliding type rheostat 4, so that the resistance of sliding type rheostat 4 changes.This change in resistance is converted into the variation of magnitude of voltage by the circuit board 43 of sliding type rheostat 4, and then the variation of this magnitude of voltage is passed to central control unit.
If the injecting systems run duration, leading screw 3 engagement occurs unusually with screw 6, and then the resistance of sliding type rheostat 4 does not change, and then controls motor by central control unit, makes it to shut down; Simultaneously, alarm device sends to medical personnel or patient with this situation by sound or optical signal.
In addition, if syringe 9 arrives predetermined near-space position, then the resistance of sliding type rheostat 4 reaches a certain setting value of master control programme, and this moment, alarm device was sounded or light alarm, notified medical personnel's medicinal liquid to inject soon.When the piston of syringe 9 has been shifted root onto, the medicinal liquid in the syringe is empty, then resistance value of reaching the limit of of sliding type rheostat 4, and then control motor by central control unit, make it to shut down, this moment, alarm device was sounded or optical signal, notified medical personnel's medicinal liquid to inject.
As can be seen from the above description, the invention provides a kind of real-time testing agency that is used for injecting systems simple in structure, with low cost, have following advantage: the ruuning situation to the actuating device of injecting systems detects in real time; Injection volume to syringe detects in real time, so that medical personnel or patient can know the ruuning situation of actuating device and the level condition in the syringe in real time, and understands syringe and whether arrives predetermined near-space and empty position.
The above is preferred implementation of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
