The results described in this document are for a device that can be used for liquids. The device can include a accommodation facility, wherein the accommodation facility includes a front end and an engine, and the configuration of the front end can be connected with the syringe. The engine can be set to be connected to the drive tube in operation,At least a portion of the drive tube is configured as an opening to respond to the engine at the first end of the housing. One or more engines and drive pipes may be alternately fixed in the accommodation. The head end of the drive tube may be configured to butt with the syringe piston included herein, directly facing an assembly for fluid scattering. The apparatus may include a housing，wherein the housing includes a first end and a motor，where the first end is configured to be able to a syringe. The motor may be configured to be operatively connected to a drive tube，Wherein at least a portion of the drive tube is configured to extend from and retreat into an opening in the first end of the housing in response to the motor. One or more engine and drive tubes may be of the recirculating type for housing use. A first end of the drive tube may be confirmed to be coupled to a piston of the syringe.Las realizaciones incluidas en este documento están dirigidas hacia un aparato que puede usarse para dispensar un fluido.
