Abstract
The utility model relates to a self-controlled electronic analgesia transfusion pump which comprises a shell body, a power supply, an electron controlling device and an electro motor. The electron controlling device is a device which can set and control the rotating times and time of the electric motor in unit time, the rotating axis of the electric motor is connected with a gear change mechanism and drives a camshaft, the top of the camshaft is provided with three convex wheels which synchronously control three brakes, the three convex wheels are respectively a liquid inlet convex wheel, a liquid crushing convex wheel and a liquid outlet convex wheel, the three brakes are respectively a liquid inlet brake, a liquid crushing convex brake and a liquid outlet brake, the closing and communication of the liquid outlet brake as well as the crushing function of the liquid crushing brake fulfill the automatically conveying and infusing of the drug liquids; thereby, the utility model is characterized in that the outputs are accurately controlled; the utility model can be give to the patients to fulfill the self-control on the condition of the dosages which are set beforehand by the medical persons according to the individual pain requirements of the patients.
Description
Technical field
This utility model belongs to the medical devices field, the specifically a kind of automatic control electronics analgesia infusion pump that can automatically, accurately control the medicinal liquid input.
Background technology
Patient's postoperative because affected part pain needs pain relieving, is obtained better effect in order to make pain relieving, adopts low dose of input mode for a long time, and the medicinal liquid that import is directly inputted to painful area.Present employed equipment is a kind of mechanical infusion pump, utilizes tension force that medicinal liquid is slowly extruded, though this mechanical type infusion pump is simple in structure, owing to structural reason, the medicinal liquid output is inhomogeneous, also difficult grasp the, the difficult oneself's control of patient.
Summary of the invention
Task of the present utility model is the defective that exists at above-mentioned mechanical type infusion pump, propose a kind of by the pain individual demand situation of medical worker according to patient, by setting dosage in advance, the output precise control can be transferred to the automatic control electronics analgesia infusion pump that the sufferer oneself controls.
The purpose of this utility model is achieved in that automatic control electronics analgesia infusion pump of the present utility model comprises housing, power supply, electronic-controlled installation and motor, above-mentioned electronic-controlled installation is one can set and be controlled at motor number of revolutions and the device of time in the unit interval, the turning cylinder of above-mentioned motor is connected with speed change gear, drive a camshaft, three locks of three cam Synchronization Control are arranged on camshaft, above-mentioned three cams are respectively the feed liquor cams, squeeze liquid cam and fluid cam, three locks are respectively the feed liquor locks, squeeze liquid lock and fluid lock, three cams with respect to the corner ordering relation of lock separately are: when the feed liquor cam is in protruding position, the fluid cam just can be in recess, squeezes the liquid cam and is satisfying above-mentioned two condition lower cam positions extruding; When the fluid cam is in protruding position, squeeze liquid cam recess, feed liquor cam recess; Feed liquor lock and fluid lock can be by spring and inside and outside two structures that semi-closed structure combines.
What automatic control electronics analgesia infusion pump of the present utility model used is a kind of medicinal fluid bag, and this medicinal fluid bag has an elongated outlet tube, and its medicinal liquid is in vacuum state.During use, the outlet tube of medicinal fluid bag is put into automatic control electronics analgesia infusion pump, and be under the control of feed liquor lock, crowded liquid lock and fluid lock, the direction of the medicinal fluid bag output mouth of pipe is consistent with the direction of fluid lock.When the feed liquor cam was in protruding position, the feed liquor lock cut out tube for transfusion, and at this moment, the fluid cam just can be in recess, and the tube for transfusion conducting at fluid sluice gate place is squeezed the liquid cam and is in protruding position, squeezes the liquid lock tube for transfusion is flattened, and medicinal liquid is injected into patient's affected part from tube for transfusion; When the fluid cam was in protruding position, the fluid lock cut out tube for transfusion, avoided medicinal liquid to reflux, and squeezed the liquid cam this moment and was in recess, and the feed liquor cam is in recess, and tube for transfusion restores, and medicinal liquid flows into tube for transfusion from medicinal fluid bag.
Three cams on its camshaft of automatic control electronics analgesia infusion pump of the present utility model are subjected to Electric Machine Control, number of times and the time that motor rotates in the unit interval can accurately be controlled and be set in to electronic-controlled installation, therefore realize the predefined dosage of pain individual demand situation of medical worker easily according to patient, the output precise control, and can transfer to the automatic control electronics analgesia infusion pump that the sufferer oneself controls.
Description of drawings
Fig. 1 is the structural representation of automatic control electronics analgesia infusion pump of the present utility model.
Fig. 2 is that feed liquor cam of the present utility model, crowded liquid cam and the synchronous turned position of fluid cam concern sequential schematic.
Fig. 3 is the structural representation of feed liquor lock of the present utility model and fluid lock.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, automatic control electronics analgesia infusion pump of the present utility model comprises housing 1, power supply 2, electronic-controlled installation 13 and motor 3, above-mentioned electronic-controlled installation 13 is one can set and be controlled at motor number of revolutions and the device of time in the unit interval, the turning cylinder of above-mentioned motor 3 is connected with speed change gear 4, this speed change gear is the secondary transmission of a worm and gear and gear train, through speed change rear drive one camshaft 7, three locks of three cam Synchronization Control are arranged on camshaft 7, above-mentioned three cams are respectively feed liquor cams 5, squeezing liquid cam 8 and 10, three locks of fluid cam is respectively feed liquor lock 6, squeeze liquid lock 9 and fluid lock 11.The outlet tube 12 of medicinal fluid bag is in feed liquor lock 6, squeezes under the control of liquid lock 9 and fluid lock 11.
As shown in Figure 2, feed liquor cam 5, squeeze liquid cam 8 and fluid cam 10 synchronous turned positions and concern that sequential schematic represents that when feed liquor cam 5 was in protruding position, fluid cam 10 just can be in recess, squeeze liquid cam 8 and finish protruding under above-mentioned two conditions and push satisfying; When fluid cam 10 is in protruding when position, squeeze liquid cam 8 recess, feed liquor cam 5 recess are finished the feed liquor of tube for transfusion.
As shown in Figure 3, feed liquor lock 6 and fluid lock 11 can be the structures that is combined by spring 16 and interior semi-closed structure 15 and outer semi-closed structure 14.This structure has elasticity, and it is more reliable to make that feed liquor lock 6 and fluid lock 11 block tube for transfusion 12, better effects if.
