Detailed description of the invention
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with drawings and the specific embodiments, this utility model is described further.
A kind of Novel injection pump as shown in Figures 1 to 5, comprises the ingredients such as housing 1, motor 2, propulsive mechanism, displacement transducer.Described motor 2, propulsive mechanism and displacement transducer are installed in the inside of housing 1.Housing 1 outside is provided with the position of displacement transducer the needle stand be connected with external system at corresponding motor 2.
The top of housing 1 is provided with feed tube 6 and a drain pipe 7, is equipped with non-return mechanism 8 in the tube chamber of described feed tube 6, drain pipe 7, is provided with liquid reservoir between the mouth of pipe in case inside one end of described feed tube 6, drain pipe 7 and propulsive mechanism piston 4.
The "T"-shaped check-valves that described non-return mechanism 8 comprises a disk body 8-1 and is arranged on disk body 8-1, described disk body 8-1 is provided with the water hole 8-2 of a central through hole and some up/down perforations, and described water hole 8-2 is distributed on around central through hole.The dash pad 8-3 that "T"-shaped check-valves is made up of an an elastomeric material and connecting rod 8-4 is formed, and connecting rod 8-4 runs through disk body 8-1, and its one end is connected with dash pad 8-3, and the other end is provided with the spacing preiection 8-4 that a diameter is greater than central through hole.Described dash pad 8-3 is stuck in disk body side (disk body water outlet side), and its area need cover whole water hole 8-2, as shown in Figure 4.
Described feed tube 6 is docked by mouthpiece 6-1 and connection tube 6-2 and forms, and drain pipe 7 is docked by mouthpiece 7-1 and connection tube 7-2 and forms, and described mouthpiece and butt tube are spliced to form the groove blocking non-return mechanism disk body 8-1 in its junction, as shown in Figure 3.Housing 1 end is provided with a mount pad 5, and described connection tube is by screwed on mount pad 5, and mount pad 5 is provided with in the position of corresponding feed tube, the drain pipe mouth of pipe tube chamber being communicated to described liquid reservoir.As shown in Figure 2 and Figure 3, the symmetrical configuration of described feed tube 6 and drain pipe 7, non-return mechanism 8 then puts upside down setting in liquid inlet and outlet pipe, and direction is contrary.
Described propulsive mechanism comprises screw rod 3, be enclosed within the sliding sleeve on screw rod 3 and be arranged on the piston 4 on sliding sleeve top, and described sliding sleeve is connected with screw rod 3 by screw thread, retrains by position-limit mechanism, and when bolt rotary, sliding sleeve only can move forward and backward on screw rod 3.Piston 4 is arranged on the top of sliding sleeve, screw rod 3 bottom by shaft coupling with the output shaft of motor 2 be connected.
During the work of this utility model syringe pump, drive screw rod 3 to rotate by motor 2, thus it is movable to order about piston.In piston 4 advance process, the effect of liquid body pressure, in drain pipe 7, the dash pad 8-3 of non-return mechanism 8 digs, and the medicinal liquid in liquid reservoir is extruded by drain pipe 7.And the dash pad 8-3 in feed tube 6 is adjacent to disk body 8-1 under hydraulic action, avoid the situation occurring to flow backwards.Piston 4 retreats, and by suction function, in feed tube 6, dash pad is dug, and medicinal liquid enters liquid reservoir, and drain pipe 7 is under non-return mechanism effect, also can not produce refluence.
