Embodiment one:
The injection device of present embodiment comprises syringe pump and syringe, and syringe pump comprises syringe installation position and the push-pull mechanism that is used for injector-actuated, and syringe pump also comprises the syringe size recognition device, is used to discern the size of syringe.
As depicted in figs. 1 and 2, syringe pump comprises syringe installation position 10, push-pull mechanism and syringe size recognition device.Syringe installation position 10 comprises two inclined-planes 11 that are used to support syringe, two inclined-planes can form a V-type groove, comprise that also the cylindrical shell that is used for syringe carries out fixed injection fixed bit 12, this injection fixed bit 12 is arranged on an end of the close push-pull mechanism of syringe installation position 10, for example be designed to a draw-in groove structure, be used to block the shelves limit of back end of syringe, avoid that the syringe of syringe moves with push rod in the injection process.Push-pull mechanism is used for the push rod of injector-actuated, and syringe is injected automatically.When syringe is placed on the syringe installation position 10 of syringe pump, syringe pump detects the size identification signal of returning from syringe by detecting unit 40, and detected size identification signal judged output is carried out signal to push-pull mechanism or other and is used for actuator that injection process is controlled according to judged result.
This utility model is mainly discerned the diameter and/or the length of syringe.As shown in Figure 1, during the diameter of identification syringe, the detecting unit 40 that is used to discern syringe diameter is arranged on the inclined-plane, and specifically being provided with highly as required of detecting unit 40 decided.When a certain syringe was placed on the inclined-plane 11, if detecting unit 40 does not detect the size identification signal of returning from syringe, then this syringe can't be by the identification authentication; If the diameter of syringe just in time makes syringe be pressed on the detecting unit 40 or and detecting unit 40 between distance within the specific limits, then detecting unit 40 can detect the size identification signal of returning from syringe, and this syringe is by the identification authentication.Angle between two inclined-planes 11 can be provided with as required, and angle is more little, and detection sensitivity is high more, and accuracy of identification is higher.
As shown in Figure 2, during the length of identification syringe, be arranged on the detecting unit 40 that on the inclined-plane 11 at least two are used to discern injector length and keep different distances respectively with between the injection fixed bit 12.When a certain syringe is placed on syringe installation position 10, if what cylindrical shell linked to each other with syringe needle one corrects and is pressed on one or more detecting unit 40, perhaps and the distance between the detecting unit 40 within the specific limits, these detecting units 40 can detect the size identification signal of returning from syringe, if detect the threshold values that the quantity of the detecting unit 40 of size identification signal equals to preset, then this syringe can be by the identification authentication.When for example using the length of a certain syringe of three detecting units, 40 identifications, default threshold values can be two detecting units 40, if do not have detecting unit 40 to detect the size identification signal or only have a detecting unit 40 to detect the size identification signal, the length that shows this syringe is too small, can't be by the identification authentication; If three detecting units 40 all detect the size identification signal, show that the length of this syringe is excessive, can't be by the identification authentication; If two detecting units 40 detect the size identification signal, show that the length of this syringe meets the requirements, by the identification authentication.Decide as required the quantity and the position of detecting unit 40, and the spacing between a plurality of detecting units 40 is more little, and detection sensitivity is high more, and accuracy of identification is higher, and the distance that for example can be provided with between each detecting unit 40 is 0.5mm.
