Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that spring top bead matches with nut the enlarged diagram located.
Detailed description of the invention
In the present invention, with horn-like inlet pipe mouth one end for forward direction, oppositely (hand-operated clamping handle one end) is for backward.
As depicted in figs. 1 and 2, intravenous injection flow controller of the present invention comprises caliper, caliper comprises hinged two halves slit bamboo or chopped wood, two halves slit bamboo or chopped wood on rear side of pin joint is as hand-operated clamping handle 13 for user hand-held, and two halves slit bamboo or chopped wood on front side of pin joint 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; The hose of infusion apparatus clamping left clamp 6 of side, chamber 12 or right clamping body 1 are provided with infrared sensing emitter 2, correspondingly with infrared sensing emitter 2 on the right clamping body 1 of hose of infusion apparatus clamping chamber 12 opposite side or left clamp 6 are provided with infrared sensing receptor 10;
Left clamp 6 or right clamping body 1 are provided with electric control gear (electric control gear is prior art, figure do not show) and arrange display module 11, and electric control gear connects respectively and describedly arranges display module 11, infrared sensing emitter 2 and infrared sensing receptor 10.
The corresponding through hole 14 being provided with up/down perforation on the hose of infusion apparatus clamping left clamp 6 at rear, chamber 12 and right clamping body 1, on left clamp 6 or right clamping body 1, (Figure 1 shows that on right clamping body 1) is provided with miniature clockwise and anticlockwise motor 3 in through hole 14 place, 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; Right clamping body 1 or left clamp 6 are fixedly connected with locating piece 16 in through hole 14 position, locating piece 16 are provided with spherical bearing 7, slidably connect nut 8 in spherical bearing 7, nut 8 is threaded on described leading screw 4; Be provided with spring top bead 9 in spherical bearing 7, spring top bead 9 crimps mutually with described nut 8 outer surface.
Spring top bead 9 pushes up pressure nut 8 outer surface, and the force of sliding friction between the decorative pearl on top of an official cap and nut 8 is greater than rotation friction when leading screw 4 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 and hose of infusion apparatus clamp chamber 12 and be connected.Thus 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, arrange display module 11, infrared sensing emitter 2 and infrared sensing receptor 10 and be 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, arrange display module 11 and infrared sensing receptor 10 is also arranged on left clamp 6.
During use, operator (medical personnel or sufferers themselves) clamps hand-operated clamping handle 13 with hands, left and right clamp 6,1 is made to open, drive leading screw 4 away from spherical bearing 7, because now miniature clockwise and anticlockwise motor 3 does not drive leading screw 4 and rotates, therefore can not there is relative motion because of rotation with nut 8 in leading screw 4, but the frictional force overcome between spring top bead 9 with nut 8 drive nut 8 to move with leading screw 4 and right clamping body 1, now nut 8 outer rim is slided in spherical bearing 7 inner ring, thus 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, therefore leading screw 4 still drives nut 8 together to move axially), completes the clamping to hose of infusion apparatus.
After the action of clamping hose of infusion apparatus completes, opening power, arranges flow by arranging display module 11.Electric control gear receives the distance signal that infrared sensing receptor 10 sends, and the flow being converted in hose of infusion apparatus (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%; After left and right clamp 6,1 clamps, hose of infusion apparatus clamping chamber 12 reduces, thus compression hose of infusion apparatus, the fluid flow in it is diminished.Those skilled in the art have the ability by testing the relation between the open degree distance signal of the left and right clamp 6,1 drawn voluntarily given by infrared sensing receptor 10 and flow, and be preset in electric control gear, enable electric control gear calculate flow in hose of infusion apparatus according to the distance signal that infrared sensing receptor 10 sends).Electric control gear compare the flow value of setting and its convert after the size of actual flow value, thus corresponding control miniature clockwise and anticlockwise motor 3 forward or reverse, leading screw 4 is rotated in nut 8, thus make left and right clamp 6,1 close to each other or away from, final regulating transfusion device flexible pipe, by the flat degree of pressing, makes actual flow value equal with setting flow value.Reach the automatic control to fluid flow size.In the process, leading screw 4 is driven to rotate by miniature clockwise and anticlockwise motor 3, the frictional force of nut 8 under the pressure on top surface effect of spring top bead 9 can not be overcome, 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, thus automatically regulate the opening degree of left and right clamp 6,1, thus 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 control to coordinate display module and drip off alarm at liquid, very safe.
