Abstract
The utility model relates to a two-purpose rotary and propelling syringe which is composed of a needle cylinder, a piston and a piston handle connected with the piston, wherein a hand wheel is fixedly connected with the piston handle. The utility model is characterized in that the piston handle is connected with a screwed sleeve, and the piston handle is a screw thread rod type piston handle which is engaged with the threaded sleeve. A groove is arranged on the piston handle, and digital scales are fixed in the groove. The utility model has the advantages of simple structure, flexible and convenient use, and accurate control of the injection velocity.
Description
Technical field:
This utility model relates to a kind of syringe, particularly relates to the dual-purpose syringe of a kind of rotating propulsion type.
Background technology:
At present the clinical syringe that generally uses is axial advance formula syringe, its shortcoming be when the injection drug liquid measure than greatly the time, must in addition permanent thrust, require great effort during operation; If the medicinal liquid of injection be need finish within a certain period of time the time, as to require the per minute requirement be 1 milliliter or 0.5 milliliter even still less the time, is difficult to control concerning the operator, do not reach the doctor's advice requirement, that is to say that injection speed can't accurately control.
Summary of the invention:
The purpose of this utility model is to provide a kind of rotating propulsion type dual-purpose syringe, and the piston handle axial advance is become rotary propelling by the interlock of screw thread phase, and is laborsaving to reach injection, and is easy to control injection speed, and it is simple in structure, and is flexible and convenient to use.
The technical solution of the utility model is achieved in that the dual-purpose syringe of a kind of rotating propulsion type, by syringe and piston and coupled piston handle, being fixedly connected with handwheel on piston handle forms, it is characterized in that: be connected with screw shell on the piston handle, piston handle is screw thread rod-type piston handle and screw shell engagement, have groove on piston handle, the groove internal fixation has digital calibration.
Good effect of the present utility model is: simple in structure, flexible and convenient to use, can accurately control injection speed.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described, as shown in Figure 1, the dual-purpose syringe of a kind of rotating propulsion type, by syringe 1 and piston 2 and coupled piston handle 4, be fixedly connected with handwheel 5 and form on piston handle 4, it is characterized in that: be connected with screw shell 3 on the piston handle 4, piston handle 4 is screw thread rod-type piston handle and screw shell 3 engagements, have groove 6 on piston handle 4, groove 6 internal fixation have digital calibration.
To hand on piston handle 4 during the medicinal liquid suction, and twitch piston 2 and draw medicinal liquid; If the injection drug liquid measure is less and need not control injection speed the time, can adopt pusher injection by conventional syringe, promptly directly propelling piston handle 4 makes it exert pressure for piston 2 to inject.When the injection drug liquid measure more maybe will be controlled injection speed, should adopt rotary propelling by the interlock of screw thread phase; Be the hand position that behind the aspiration medicinal liquid screw shell 3 is rotated to regulation, according to thread pitch rotation hand wheel 5 bolt type piston handle 4 progressive length that whenever rotate a circle as can be known, this length with numerical reference on bolt type piston handle 4.Be that injectable is laborsaving and be easy to control injection speed.
