Description of drawings
Accompanying drawing 1 is the automatic infusion pump sketch map.
Among the figure: control panel 1, door closure 2, installing plate 3, pressure transducer 4, press block 5, peristaltic tablet 6, pipe clamp 7, tube seat 8, chuck 9, gas bubble detection 10, foil gauge 11, snap close 12, hinge 13, door closure concave surface 14, half round cut 15, extrude bar 16, dead bolt 17, pipe pressing plate 18, semicircle groove 19, semicircle notch 20, liquid crystal display 21, function button 22, press down liquid device 23.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment essentiality content of the present utility model is described in further detail:
As shown in drawings: a kind of automatic infusion pump, its profile is the case and bag shape with handgrip, the panel left side of infusion pump is control panel 1, the right side is door closure 2, be installing plate 3 in the door closure 2, installing plate 3 is provided with pressure transducer 4, pressure block 5, peristaltic tablet 6, gas bubble detection 10, pipe clamp 7 and presses down liquid device 23.First tube for transfusion is embedded in the installing plate 3 upper end pipe clamps 7, embed again in the tube seat 8 in the gas bubble detection 10, then tube for transfusion is embedded in the pipe clamp 7 at peristaltic tablet two ends about in the of 6, then tube for transfusion is put into the foil gauge 11 of pressure transducer 4 and the tube seat 8 between the pressure block 5, because foil gauge 11 interior flexible devices, so foil gauge 11 can telescopic moving, and is comparatively tight with the attaching of tube for transfusion, and be not subjected to the interference effect of the factors such as door closure distortion, hinge be loosening.Liquid in the tube for transfusion produces deformation to pressure transducer 4 foil gauges 11, and the size of deformation quantity has been reacted the size of pressure in the pipeline, finally through infusion pump systems infusion process is detected.Tube for transfusion is placed in the tube seat 8 that presses down liquid device 23 of its lower end through the tube seat 8 of pressure transducer 4, when door closure is opened, is provided with tightening device because pressing down in the liquid device 23, tube for transfusion can be compressed so press down the handle of liquid device 23, makes the medicinal liquid cutout in the pipe; And when door closure was closed, the extrude bar 16 in the door closure 2 was passed handle to the left, and the tube for transfusion of this moment opens, and medicinal liquid is just along the tube wall drip.Door closure 2 inner concaves designs is for gas bubble detection 10, pressure transducer 4 etc. arranges the space, and situation produces even if door closure distortion, hinge be loosening etc., all can interference effect pressure transducer 4 and the normal operation of gas bubble detection 10.The half round cut 15 of door closure 2 upper and lower sides is to allow tube for transfusion pass through when door closure 2 closure.During door closure 2 closure, the semicircle groove 19 of door closure 2 interior pressure tube plates 18 just in time fastens tube for transfusion, and respectively there is a semicircle notch 20 on both sides, pressure tube plate 18 centre, and this notch 20 interlocks with the chuck 9 on peristaltic tablet 6 both sides, makes tube for transfusion closely attach peristaltic tablet 6.Door closure 2 is connected with installing plate 3 by hinge 13, and the dead bolt 17 of door closure 2 interlocks with the snap close 12 on the installing plate 2.Control panel 1 is provided with LCDs 21 and function button 22.
