The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.
As Fig. 1, shown in Fig. 2, the utility model discloses a kind of medicinal liquid aspirator, comprise microscope carrier 10, suction module, self-clamping module, photo module and control module (not shown).
Suction module comprises that peristaltic pump 21, the first needle set 22, the second needle set 23, ampoule bottle 24 and mother liquid multi-cavity bottle 25, the first needle sets 22 and second needle set 23 one end are connected with peristaltic pump 21, and the other end is connected with ampoule bottle 24 and mother liquid multi-cavity bottle 25 respectively.
Self-clamping module is positioned on microscope carrier 10, comprises cylinder 31 and gripper jaw 32, and cylinder 31 is controlled opening and closure of gripper jaw 32, and gripper jaw 32 is provided with U-shaped groove 33.
Photo module comprises camera 41 and backlight plate 42, and camera 41 and backlight plate 42 are positioned at the two ends of gripper jaw 32, backlight plate 42 vertical with U-shaped groove 33 and with the sight line of camera 41 on same axis.This structure is conducive to light and sees through gripper jaw 32, facilitates camera 41 imagings.
Control module is provided with vision program and trace routine, and vision program is used for according to the height of the graphical analysis aspiration medicinal liquid gathering, and trace routine is used for analyzing medicinal liquid suction ratio and controls peristaltic pump 21 actions.
The operation principle of this utility model is: the first needle set 22 on peristaltic pump 21 is inserted in ampoule bottle 24, first image that camera 41 gathers ampoule bottle 24 is to control module, the vision program analysis of control module goes out the liquid level of current ampoule bottle 24 herb liquids to the bottle height at the end, and saves as total height.Then control module sends a signal that starts aspiration medicinal liquid to peristaltic pump 21.The medicinal liquid that the first needle set 22 on peristaltic pump 21 extracts in ampoule bottle 24, and by the second needle set 23, medicinal liquid is delivered in mother liquid multi-cavity bottle 25.Camera 41 gathers image to control module on one side, the trace routine of control module is analyzed current ampoule bottle 24 herb liquids to the bottle residual altitude at the end, trace routine deducts residual altitude by total height and obtains suction height, suction height asks ratio to calculate with total height, the ratio obtaining is exactly current suction ratio, Zong send a signal that stops suction at once peristaltic pump 21 when the aspiration medicinal liquid of suction ratio and setting is identical with medicinal liquid capacity, the medicinal liquid being drawn into be exactly current needs the medicinal liquid extracting.
The suction precision of this medicinal liquid aspirator is high, and speed is fast.Following analyzing examples:
If picking rate frame each seconds 15 of camera, every frame need to be used 66 milliseconds, and the image analysis calculation time is 20ms; Peristaltic pump adopts 485 communications, and the baud rate of communication is 9600 b/s, and stop signal needs the data of 6 bytes, and the communication time that used is 6 ms; The speed of peristaltic pump suction is that 15ml is per minute, and the medicinal liquid of every millisecond of suction is 0.00025 ml.The time that suction 10ml medicinal liquid needs only needs 40s, and the speed of suction is compared and is significantly increased with weighting manner.
Minimum error is analyzed as follows: when collecting last image, remaining medicinal liquid is that total medicinal liquid deducts the medicinal liquid that needs suction just.To peristaltic pump work, stopping the needed time is: the time=26ms of time+peristaltic pump communication of graphical analysis, the medicinal liquid pumping out is 26ms * 0.00025ml/ms=0.0065ml more.So minimum error is 0.0065ml.
Maximum error is analyzed as follows: when gather last image time, during last the image suction ratio that infinite approach has needed, last image acquisition time also can cause the many extracting liquids of peristaltic pump, so to actual peristaltic pump dwell time, the time of the many suctions of peristaltic pump is: image acquisition time+graphical analysis time+peristaltic pump communication time=92ms, the medicinal liquid of many suctions is 92ms * 0.00025ml/ms=0.023ml.
From analyzing above: the medicine bottle of 10ml specification of take is example, and according to maximum Error Calculation, error ratio is 0.023ml/10ml * 100%=0.23%, suction precision is 99.77%, and when medicine bottle is with a higher standard, ratio of precision regular meeting improves accordingly thereupon.
The above; it is only the preferably specific embodiment of this utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
