Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Fig. 1 is the internal structure schematic diagram that trace plays water liquid-drop machine, and as shown in Figure 1, trace plays water liquid-drop machine 10 and has shell 13, volume-adjustment unit, injecting unit and bullet water unit.
Injecting unit comprises button 11, push rod 12, piston 21, piston rod 19, air cavity 22 and dropper 31.Piston rod 19 is fixedly connected on the below of push rod 12, piston 21 is connected with piston rod 19, piston 21 moves reciprocatingly under the promotion of piston rod 19 in air cavity 22, dropper 31 for directly draw and receiving medical liquids, for removably connecting between dropper 31 and air cavity 22.
Connected mode between push rod 12 and thread depth regulating block 14 as shown in Figure 2, push rod 12 has outstanding key 122, thread depth regulating block 14 has keyway accordingly, can slide up and down between key 122 and keyway.
Volume-adjustment unit comprises thread depth regulating block 14, slide block 15, spring part 16, and limited block 17.Thread depth regulating block 14 is threaded with outer casing inner wall, is moved up and down in shell 13 by screw thread, regulating the distance between limited block 17, for being fixedly connected with between slide block 15 with push rod 12, and not being connected between slide block 15 with shell 13.Limited block 17 is fixedly connected with between shell, and push rod penetrates the hole in the middle of limited block 17.Slide block movement cannot will be moved downward by stopping to limited block 17 again, after release button, at spring part 16 by slide block 15 fight back, and the original position thus drive push rod 12 moves back.Rotate thread depth regulating block 14 with the stroke of adjusting slider 15, thus regulating piston expellant gas volume, be also the medicine liquid volume that air cavity 22 can suck.
Play water unit and comprise inclined-plane 121 and Billiard apparatus 18.Inclined-plane 121 is arranged on one end of the close piston rod of push rod 12.As shown in Figure 3, Billiard apparatus 18 comprises Billiard apparatus shell 181 to the structure of Billiard apparatus 18, and the impact block 182 of motion in Billiard apparatus shell 181, is connected to the trip rod 183 of impact block 182 front end by rotating shaft 184.Impact block 182 front end has groove, rotating shaft 184 is arranged in groove, and groove side mask has barrier 185, and Billiard apparatus shell 181 position corresponding to groove has corresponding breach, when trip rod 183 turns left in the direction of the arrow, trip rod 183 is moved in breach.The direction that the direction of breach and groove increases towards the thickness on inclined-plane 121, the i.e. opposite direction of push rod 12 direction of motion during injecting fluid.Be connected with Billiard apparatus shell 181 inside by Billiard apparatus spring inside impact block 182.Under original state, the Billiard apparatus spring of impact block 182 inside is in relaxed state, and impact block 182 is in the front end of Billiard apparatus shell 181, and trip rod 183 extends over inclined-plane 121 Transverse to the length of stretching out.When push rod 12 as shown in Figure 1 moves downward, drive inclined-plane 121 to move downward, as shown in Figure 1, trip rod 183 can be promoted in shell 181 when inclined-plane 121 moves downward, the Billiard apparatus spring of compression impact block 182 inside.When inclined-plane 121 continues the end moving downward inclined-plane, the Billiard apparatus spring of impact block 182 inside promotes trip rod 183 and clashes into push rod 12, thus push rod 12 is vibrated, vibrate and be transmitted to the front end of dropper 31 by the outer wall of air cavity 22 thus the microlayer model of the front end being adsorbed on dropper 31 is shaken.
When release button 11, push rod 12 moves upward, and drives inclined-plane 121 to move upward.The thickness on inclined-plane 121 is less than the height of Billiard apparatus shell 181, be greater than the length that trip rod 183 trails, when trip rod 183 is encountered in the thickness on inclined-plane 121, trip rod 183 upwards rotates, as shown in Figure 4, now trip rod 183 can not stop the motion on inclined-plane 121.After push rod 12 moves upward end, trip rod 183 restPoses.
In order to ensure that trip rod 183 still can recover the original state launched when trace bullet water liquid-drop machine 10 laterally uses, in rotating shaft 184, torque spring can be installed, apply torsion contrary with the direction of arrow in Fig. 3 position to trip rod 183.
The use procedure that trace plays water liquid-drop machine is as follows:
First volume aspirated is regulated, turn knob 11, push rod 12 is driven to rotate, push rod 12 connects drive thread depth regulating block 14 by key and rotates in shell 13, thus it is mobile in shell 12 to promote slide block 15, because slide block 15 is fixedly connected with push rod 12, therefore the distance between adjusting slider 15 and limited block 17, can the distance that moves up and down of regulating pushing rod 12, i.e. the distance that moves up and down in air cavity 22 of piston 21, thus the volume of the medicinal liquid regulating air cavity 22 can be drawn by dropper 31.
Draw medicinal liquid, after regulating volume aspirated, after button is subject to downward power, promotion push rod 12 and slide block 15 move downward, thus promotion piston 21 discharges the air in air cavity 22.Soak into the liquid by dropper 21, release button 11, push rod pops into position by spring part 16, thus drives piston upwards, is sucked by medicinal liquid in dropper 31.
Drip medicinal liquid, to drip to eye.The liquid outlet of dropper 31 is made to be suspended from above eye, press the button 11, push rod 12 drives piston 21 that medicinal liquid is released air cavity 22, when push rod 12 moves downward, inclined-plane 121 is driven to move downward, compressed by trip rod 183 in Billiard apparatus shell 181, the spring now in Billiard apparatus shell 181 is in compressive state.When inclined-plane 121 continues to move downward, when trip rod 183 arrives the end on inclined-plane, the Billiard apparatus spring of impact block 182 inside promotes impact block and outwards moves, promote the front end impact push rod 12 of trip rod 183, thus push rod 12 is vibrated, vibrate and be transmitted to the front end of dropper 31 by the outer wall of air cavity 22 thus the microlayer model of the front end being adsorbed on dropper 31 is shaken.
A window can be opened in the position that shell 13 is corresponding with thread depth regulating block 14, mark corresponding scale to show the volume of imbibition.The mask method of scale is specific as follows: the volume of imbibition according to the pitch of screw thread on thread depth regulating block 14, can converse the displacement after rotation one circle.Thus calculating the stroke of slide block 15, the stroke of slide block 15 is equal with the distance that piston 21 moves downward, and the internal diameter according to air cavity 22 can calculate expellant gas volume.Known, the move distance of expellant gas volume and thread depth regulating block 14 is linear.The scale of imbibition volume can be marked out according to this linear relationship.
