Especially, the utility model is equipment which is applied to water perfusion for an endoscope in the urinary surgery. The utility model is characterized in that the utility model comprises a liquid pump, an overflow valve and a flow capacity controller for a liquid pump, wherein, the flow capacity controller for a liquid pump comprises a flow capacity regulator connected with the liquid pump, and switch power supply which can make alternating current converted to direct current; the overflow valve is connected with the liquid pump by a water inlet pipe and a water outlet pipe; the flow capacity regulator is a potentiometer which is connected between the switch power supply and the liquid pump. The utility model has the advantages of simple structure, lower manufacture cost and operation cost, easy control for flow capacity, convenient use and operation, safety, reliability and long service life.
Description
Technical field:
This utility model relates to a kind of Medical injection pump, and it belongs to medical auxiliary equipment, particularly a kind of equipment that is applied to the water filling of Urology Surgery endoscope.
Background technology:
The charge pump that uses at present is to adopt rotary extrusion type spinning vacuum principle both at home and abroad, utilizes the motor rotation, drives swiveling wheel, the extruding silica gel tube forms negative pressure, and cleaning solution is extracted out from container, be filled into endoscope's tract, be transported to stone location, equal to make by oneself a liquid pump.Regulate flow with endoscope's switch during operation technique, need sometimes to stop.The rotation of motor is a constant speed, in order to change rotating speed of motor and to stop, need adding a pressure transducer, thereby according to the variation of flow in the operation, changes rotating speed of motor and stop.Therefore there is following defective in above-mentioned charge pump: the service life of the silica gel tube that is often pushed is short; Pressure transducer itself just compares at the end service life; Because device structure link complexity, using method is more complicated also, is not easy to grasp, and is not easy operation.
Summary of the invention:
It is a kind of simple in structure that the purpose of this utility model is to provide, and operational approach is simple, and flow-control is flexible, the Medical injection pump of long service life.
The purpose of this utility model is achieved in that
A kind of Medical injection pump is characterized in that it comprises a liquid pump, overflow valve and liquid pump volume control device; Described liquid pump volume control device comprises that one is connected the flow regulator on the liquid pump and alternating current is converted to galvanic Switching Power Supply; Described overflow valve is connected with liquid pump by the water inlet pipe outlet pipe.
Described flow regulator is a potentiometer, and described potentiometer is connected between Switching Power Supply and the liquid pump.
Between described liquid pump and flow regulator, also be provided with a display that is used to show fluid flow.
This utility model is simple in structure, and manufacturing and operating cost are all lower; Flow-control is easy, use and easy to operate, and safe and reliable, long service life.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is the A-A cutaway view of this utility model accompanying drawing 1
Accompanying drawing 3 is the syndeton sketch map between this utility model overflow valve and the liquid pump
Accompanying drawing 4 is a work system block diagram of the present utility model
The specific embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2,3,4 below, this utility model be further detailed:
In the present embodiment, this utility model is by a liquid pump 1, overflow valve 5 and liquid pump volume control device; Described liquid pump volume control device comprises that one is connected the flow regulator 7 on the liquid pump 1 and alternating current is converted to galvanic Switching Power Supply 4.Described flow regulator 7 is a potentiometer, described potentiometer is connected between Switching Power Supply 4 and the liquid pump 1, after the alternating current process Switching Power Supply 4 of 220V, to become the DC voltage of 12V, utilize knob to regulate the size that potentiometer changes DC voltage, thereby realize changing the purpose of motor speed.Regulative mode is simple to operate like this, easily control.Between described liquid pump 1 and flow regulator 7, also be provided with a display that is used to show fluid flow.The display 6 that shows fluid flow can be a D.C. voltmeter, the magnitude of voltage that shows directly is converted into flow shows.Also be provided with a display lamp 9 at Switching Power Supply 4 places.Described overflow valve 5 is connected with liquid pump 1 with outlet pipe 52 by water inlet pipe 51.Shown in the accompanying drawing 1,2 is outlet; 3 is electric fuse, and 8 is switch.
Work process of the present utility model is as follows:
As shown in accompanying drawing 3: in the time of normal the use, flushing liquor sucks liquid pump 1 from water inlet 53, after liquid pump 1 pressurization, enter overflow valve 5 from the B mouth, when outlet diminishes or closes, liquid pump 1 is also in work, water inlet that does not stop and water outlet, pressure and flow are constant, and pressure is upwards pushed valve body C open, water forms the A---liquid pump---B---circulation of D---F---A by flowing back in the liquid pump 1 under the outlet D warp that leads to outlet pipe 52.When outlet was opened, valve body C will block towards the outlet D of outlet pipe 52 because gravity sets back, current by water inlet through A to liquid pump, after liquid pump pressurizes, flow to water exit end B again, again from outlet 54 outflows.
Provided the operation principle block diagram of this utility model in the operation application process in the accompanying drawing 4.Described endoscope is connected the water side of overflow valve 5, and spilling water directly enters the flushing liquor container by pipeline.
