Abstract
The utility model discloses a controllable liquid pump which is mainly composed of a ball-shaped pump, a prefill valve and a suction valve. The controllable liquid pump is characterized in that the prefill valve and the suction valve are positioned on the same axial line. The utility model has the advantages of artful design and reasonable mechanical structure. For the prefill valve and the suction valve are designed on the same longitudinal axial line, the two valves are reversely opened simply and reliably, the two valves are synchronous all the time with the same size, and the function of the liquid under the pressure of negative direction is improved. The controllable liquid pump effectively overcomes the defect that the increase of operating time and the trouble of the patient operating control are caused by the design of operation which makes contrast existing in the sizes of opening.
Description
Technical field:
This utility model relate to a kind of need with hydraulic control also can be implanted in controlled liquid pump in the intravital medical apparatus and instruments, particularly relate to the suction valve and the prefill valve of the controlled liquid pump of this kind.
Background technology:
Be implanted in the intravital medical apparatus and instruments existing, the unlatching of suction in the controlled liquid pump and topping up valve because operational design makes the size of unlatching exist difference, thereby brings the prolongation of operating time, has increased patient and has operated trouble in the control.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, is convenient to the controlled liquid pump of patient's operation.The technical scheme that its technical problem that solves this utility model adopts is, a kind of controlled liquid pump mainly is made up of ball pump, prefill valve and suction valve, and its characteristics are: prefill valve and suction valve are positioned on the same axis.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, this utility model is skillfully constructed, reasonable mechanical structure because prefill valve and suction valve are designed on same longitudinal axis, makes the reverse unlatching of two valves more simple and reliable, make the unlatching of two valves synchronous all the time, size is consistent, has improved liquid function under negative pressures, has certain popularization value.
Description of drawings:
Below in conjunction with drawings and Examples this utility model is described in further detail.
Fig. 1 is the cutaway view of this utility model structure;
Fig. 2 is the vertical view of this utility model structure.
The specific embodiment:
Among the figure, the prefill valve of this controlled liquid pump and suction valve design are on same longitudinal axis, and the upper end is a suction valve 60, and the lower end is a prefill valve 50, and the bottom of controlled liquid pump is a ball pump 70, and control knob 40 is arranged in the middle of three connection tubes 10,20,30.The valve design globulate plug 80 of prefill valve, an end of ball plug is made sphere, makes it under the thrust and spring 51 effects of fluid pressure or axostylus axostyle, reliably the valve of opening and closing prefill valve.And the other end of ball plug can embed in the small end of tapered coil spring 51, stablizes and reliable duty thereby make spring be in one all the time, and makes spring keep stable to the pressure of ball plug, helps the service life of pressurize valve.When ball pump 70 is squeezed, liquid in the ball pump is through certain liquid road, the ball plug 80 that makes the prefill valve 50 of lower end under the pressure of liquid moves down and the prefill valve valve open, the liquid connection tube 20,30 of can directly flowing through enters required apparatus, and the liquid in the ball pump by connection tube 10 through the liquid road and non-resistance ground is additional in ball pump.When pressing control knob 40 axostylus axostyle 90 is moved down, open the valve (its valve is to combine as a whole with axostylus axostyle) of suction valve at once and promote ball plug and open the valve of prefill valve simultaneously, make liquid in the whole system under negative sense hydraulic pressure, by connection tube 20,30, behind controlled liquid pump, flow through connection tube 10, return former reservoir.This shows that the valve of being opened two valves by axostylus axostyle 90 is comparatively direct, and has adopted the mechanical type way of contact fully, thereby be to be in state fully reliably, the service life of also greatly having improved controlled liquid pump.Because control knob is arranged in the middle of three connection tubes, make connection tube play certain protective role in addition to it.Got rid of other factors and cause to control knob operation out of control, the performance of controlled liquid pump is affected.
