Abstract
The utility model discloses an extrusion mechanism of an electronic micro infusion pump in the field of medical equipment. The extrusion mechanism comprises a housing, wherein the housing is connected with a liquid inlet tube; the liquid inlet tube is connected with a liquid outlet hose arranged in the housing; a rotating tray is arranged on the internal surface of the housing; a driving roller is arranged at the periphery of the rotating tray; a pressing board corresponding to the driving roller is arranged on the outer side of the housing; and the liquid outlet hose bypasses the rotating tray and is clamped between the pressing board and the driving roller corresponding to the pressing board. As the roller performs planet wheel rotation to uniformly extrude the liquid outlet hose, liquid medicine in the hose can creep to go forward, so as to perform continuous micro infusion; regulation and control of the extrusion output can be achieved by changing the rotating speed of the driving mechanism; and the extrusion mechanism is suitable for micro, adjustable and controllable infusion conditions.
Description
Technical field
This utility model relates to a kind of armarium, particularly a kind of infusion pump.
Background technology
Infusion pump is a kind of device that is used for output liquid, gas, at present used most infusion pumps are because the amount of liquid of each output is pre-set and changeless, like this, just can not regulate during actual the use according to practical situation (as transfusion time, patient is to the difference requirement of extrusion capacity in the unit interval).
The utility model content
The purpose of this utility model is to provide a kind of extrusion mechanism of electronics trace infusion pump, makes the medicine extrusion capacity unit interval to regulate and control, and can continue trace output.
For solving above technical problem, the extrusion mechanism of electronics trace infusion pump provided by the utility model, comprise housing, be connected with feed tube on the described housing, feed tube be arranged on the intravital fluid flexible pipe of shell and be connected, described shell inner surface is provided with rolling disc, described rolling disc periphery is provided with driving rolls, the corresponding pressing plate that is provided with of hull outside, described fluid flexible pipe with driving rolls walk around described rolling disc and be connected to pressing plate and the driving rolls corresponding with pressing plate between.
In the work, medicine enters extrusion mechanism from infusion pump through feed tube, the drive mechanism turn disc, the roller that is arranged on the rolling disc periphery is done the planet gear type rotation, extruding fluid flexible pipe, make the outlet of fluid flexible pipe can extrude the medicine of stable trace, and can be the extrusion capacity of may command medicinal liquid unit interval by the rotating speed of regulating driving mechanism, compared with prior art, the beneficial effects of the utility model are: make for the extrusion capacity trace of unit interval of medicine and adjustable, the pressing plate that is provided with the housing coupling makes roller in the process of extruding fluid flexible pipe, and the fluid flexible pipe can not be extruded housing.This utility model is applicable to be needed under trace and the regulatable transfusion condition.
As improvement of the present utility model, be provided with the rolling disc groove in the described housing, rolling disc is arranged in the rolling disc groove.Make the turn disc process convenient stable.
As further improvement of the utility model, described driving rolls has a plurality of, and evenly is arranged on the rolling disc periphery through bearing pin.Further strengthened squeezing effect.
As further improvement of the utility model, described rolling disc center is provided with the polygonal shaft hole that can be connected with drive motors.Be convenient to the drive mechanism turn disc.
