Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described in further detail:
As it is shown in figure 1, the utility model discloses a kind of ultrasonic blood shunt device based on capillarity, including reagent
Container, some capillary vessels, some piezoelectric ceramic pieces and some flexible clip；Described reagent container is cylindric, and one end is closed,
Other end opening；Described some capillary vessels are arranged on the tube wall of described reagent container, and one end turns on described reagent container,
The other end and extraneous conducting；The number of described flexible clip is identical with the number of described capillary vessel, and one_to_one corresponding is arranged on institute
State on capillary vessel, for whether controlling described capillary vessel and extraneous conducting；Described some piezoelectric ceramic pieces are arranged on institute
State on the outer wall of reagent container.
This utility model gives the method to set up of a kind of piezoelectric ceramics: piezoelectric ceramic piece has three, the most a piece of setting
In the end of described reagent container blind end, additionally two panels is correspondingly arranged on the sidewall on described reagent container both sides.
Piezoelectric ceramic piece can be fixed on the outer wall of reagent container in the way of using viscose glue.
