Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram that spring top bead matches with nut and locates.
The specific embodiment
In this utility model, take horn-like inlet pipe mouth one end is forward direction, and oppositely (hand-operated clamping handle one end) is backward.
As depicted in figs. 1 and 2, intravenous injection flow controller of the present utility model comprises caliper, caliper comprises hinged two halves slit bamboo or chopped wood, the two halves slit bamboo or chopped wood of pin joint rear side is as hand-operated clamping handle 13 for user hand-held, and the two halves slit bamboo or chopped wood of pin joint front side forms right clamping body 1 and left clamp 6 and for clamping hose of infusion apparatus.
The middle part of left and right clamp 6,1 is arranged with arcuate groove, and the arcuate groove on left and right clamp 6,1 is oppositely arranged and surrounds hose of infusion apparatus clamping chamber 12; Left clamp 6 or the right clamping body 1 of hose of infusion apparatus clamping chamber 12 1 sides are provided with infrared sensing emitter 2, be provided with infrared sensing receptor 10 corresponding with infrared sensing emitter 2 on the right clamping body 1 of hose of infusion apparatus clamping chamber 12 opposite sides or left clamp 6;
Left clamp 6 or right clamping body 1 are provided with electric control gear (electric control gear is prior art, and figure does not show) and display module 11 are set, and electric control gear connects respectively described display module 11, infrared sensing emitter 2 and the infrared sensing receptor 10 of arranging.
The corresponding through hole 14 that is provided with up/down perforation on the left clamp 6 at hose of infusion apparatus clamping 12 rears, chamber and right clamping body 1, on left clamp 6 or right clamping body 1, (Figure 1 shows that on right clamping body 1) in through hole 14 places and be provided with miniature clockwise and anticlockwise motor 3, the main shaft of miniature clockwise and anticlockwise motor 3 is connected with leading screw 4 by shaft coupling 15, and leading screw 4 stretches out right clamping body 1 or left clamp 6 along through hole 14; On right clamping body 1 or left clamp 6, in through hole 14 positions, be fixedly connected with locating piece 16, spherical bearing 7 is installed on locating piece 16, slidably connect nut 8 in spherical bearing 7, nut 8 is threaded on described leading screw 4; In spherical bearing 7, be provided with spring top bead 9, spring top bead 9 and described nut 8 outer surface phase crimping.
Nut 8 outer surfaces are pressed on spring top bead 9 top, the rotation friction when force of sliding friction between the decorative pearl on top of an official cap and nut 8 is greater than leading screw 4 and rotates in nut 8 and between nut 8.
The front central of described left clamp 6 and right clamping body 1 surrounds horn-like inlet pipe mouth 17, and horn-like inlet pipe mouth 17 is connected with hose of infusion apparatus clamping chamber 12.Thereby more easily hose of infusion apparatus is put into hose of infusion apparatus clamping chamber 12 by horn-like inlet pipe mouth 17 in use.Described electric control gear is PLC or single-chip microcomputer or integrated circuit.
Described miniature clockwise and anticlockwise motor 3, spring top bead 9, electric control gear, display module 11, infrared sensing emitter 2 and infrared sensing receptor 10 are set are prior art, its concrete structure no longer describes in detail.
In shown in Fig. 1, infrared sensing emitter 2 and miniature clockwise and anticlockwise motor 3 are arranged on right clamping body 1, and spring top bead 9 is arranged on left clamp 6 by locating piece 16, display module 11 and infrared sensing receptor 10 are set and are also arranged on left clamp 6.
During use, operator (medical personnel or patient) clamps hand-operated clamping handle 13 with hands, make left and right clamp 6,1 open, drive leading screw 4 away from spherical bearing 7, cause now miniature clockwise and anticlockwise motor 3 does not drive leading screw 4 rotation, therefore can there is not relative motion with nut 8 because of rotation in leading screw 4, but overcome the frictional force of spring top bead 9 between nut 8 and drive nut 8 to move with leading screw 4 and right clamping body 1, now nut 8 outer rims are slided in spherical bearing 7 inner rings, thereby the horn-like inlet pipe mouth 17 of left and right clamp 6,1 is opened.After horn-like inlet pipe mouth 17 opens, transparent hose of infusion apparatus can be clamped in the hose of infusion apparatus clamping chamber 12 between left and right clamp 6,1.Then operator manually compresses left and right cramping body (because leading screw 4 does not rotate, so leading screw 4 still drives nut 8 together to move axially), completes the clamping to hose of infusion apparatus.
After clamping hose of infusion apparatus has moved, opening power, arranges flow by display module 11 is set.Electric control gear receives the distance signal that infrared sensing receptor 10 sends, and (when hose of infusion apparatus clamping chamber 12 is more than or equal to the cross section of hose of infusion apparatus, flow is 100% to be converted into flow in hose of infusion apparatus; After left and right clamp 6,1 clamps, hose of infusion apparatus clamping chamber 12 dwindles, thereby compression hose of infusion apparatus diminishes the fluid flow in it.Those skilled in the art have the ability to draw voluntarily the open degree distance signal of the given left and right clamp of infrared sensing receptor 10 6,1 and the relation between flow by test, and be preset in electric control gear, the distance signal that electric control gear can be sent according to infrared sensing receptor 10 calculates the flow in hose of infusion apparatus).The size of the actual flow value after the flow value that electric control gear is relatively set and its conversion, thereby miniature clockwise and anticlockwise motor 3 forward or reverse of corresponding control, make leading screw 4 in the interior rotation of nut 8, thereby make left and right clamp 6,1 close to each other or away from, the flat degree that final regulating transfusion device flexible pipe is pressed, makes actual flow value equate with setting flow value.Reach the automatic control to fluid flow size.In this process, by miniature clockwise and anticlockwise motor 3, drive leading screw 4 rotations, can not overcome the frictional force of nut 8 under the pressure on top surface effect of spring top bead 9, nut 8 can not rotate and can not axially move, leading screw 4 can only rotate in nut 8, make leading screw 4 and nut 8 have displacement to axial, thereby automatically regulate the opening degree of left and right clamp 6,1, thereby realize the automatic control to fluid flow size.
Display module 11 is set and in use shows uninterrupted in good time, very easy to use.Electric control gear can also be controlled and coordinate display module and drip off alarm at liquid, very safe.
