Disc is equipped with the groove 10 matched with wedge block 9, and first piston 2, which moves downward, can make wedge block 9 stick into groove 10 simultaneously in fact
The fixation of existing piston, the right end of piston cylinder 1 are equipped with a second piston 11 that can be moved left and right, defeated through having in second piston 11
One end of liquid pipe 12, perfusion tube 12 is connected to piston cylinder 1, and the other end is fixed with spray head 13.
In order to realize that the present apparatus facilitates the driving that is equipped with for holding and facilitating first gear 8, the left end of the piston cylinder 1 is set
There is hollow grip 14, handle 14 and piston cylinder 1 constitute a gun-shaped structure, and first gear 8 is mounted in the cavity of handle 14, the
The left side of one gear 8 is coaxially fixed with the thumb wheel 15 for being placed in 14 outside of handle, is realized by trackwheel 15 to the first tooth
The driving of wheel 8,8 warp beam of first gear are rotatably installed on the inner wall of 14 cavity of handle.
In order to realize that wedge block 9 can be moved downward and can be resetted upwards, the lower part of 1 cylinder wall of piston cylinder is equipped with one
Vertical through slot, wedge block 9 are placed in through slot, and the lower half portion of wedge block 9 stretches out the outside of piston cylinder 1 and is equipped with a level
Through-hole 16, a guide rod 17 that can be moved left and right is equipped on the left of through-hole 16, the right end of guide rod 17 is wedge shape, and guide rod 17 moves right
Dynamic to can be achieved in its wedge-shaped part insertion through-hole 16 and wedge block 9 is moved down, the bottom of wedge block 9, which is equipped with, can make it upwards
The second pressure spring 18 resetted.
For convenience of the operation of the present apparatus, the outside of the guide rod 17 is equipped with shell 19, and the lower end of shell 19 is hinged with one
Driving lever 20, the upper end of driving lever 20 are placed in lower end in shell 19 and stretch out shell 19, and the left side of guide rod 17 is equipped with the first of lower ending opening
Rectangular channel 21, the upper end of driving lever 20 are placed in the first rectangular channel 21, and the second rectangular channel 22 of lower ending opening is equipped on the left of guide rod 17,
A support rod 23 that is vertical and being fixed on shell 19, the second rectangle left cell wall and support rod are equipped in second rectangular channel 22
It is equipped with third pressure spring 24 between 23, can realize that 20 upper end of driving lever drives guide rod 17 to move right and press by stirring 20 lower end of driving lever
The trend that tight third pressure spring 24 resets it can flexible potential energy.
In order to realize that second piston 11 can be moved left and right and can be fixed, the right end of the second piston 11 is coaxially fixed with
Two male-pipes 25, the right part of piston cylinder 1 are fixed with block plate 26, and 25 screw thread spinning of the second male-pipe is defeated on block plate 26
Liquid pipe 12 runs through the second male-pipe 25, by the spinning of the second male-pipe 25 and block plate 26, so that can adjust the through screw thread
Two pistons 11 protrude into the length in piston cylinder 1, to adjust each spray value.
For the ease of observing piston cylinder capacity, the piston cylinder can be set to transparence, and on the cylinder body of piston cylinder
Setting graduation mark facilitates observation.
The specific work process of the utility model is: the anaesthetic being already equipped with is loaded in bottle by the present apparatus when in use
And be mounted at inlet, it needs to move left and right second piston 11 according to patient at this time, leads to when automatic second piston 11 in left and right
It crosses and screws the realization of the second male-pipe 25, the second male-pipe will move under itself self-locking with the screw thread on block plate 26
The second piston 11 for moving suitable position is fixed.
It pulls piston rod 4 that first pressure spring 7 is compressed to left end at this time and makes it have the trend elastic potential energy of rebound,
While pulling piston rod 4 first piston 2 is moved to the left, then this process first piston 2 squeezes wedge block 9 and makes it downwards
Mobile, wedge block 9 squeezes the second pressure spring 18 and makes it have the trend and elastic potential energy of rebound during this, when first piston 2
Move to groove 10 it is corresponding with 9 pairs of wedge block when wedge block 9 launch under the action of the bounce of the second pressure spring 18 into groove 10
It realizes the fixation to first piston 2, makes the right side of first piston 2 be moved to feed liquor when groove 10 and the cooperation of wedge block 9
Mouthful anaesthetic can flow into piston cylinder 1 through inlet at this time in left side, first piston 2 is not able to rotate, can by conventional sliding slot with
Sliding block cooperates to realize.
Due to moving left and right for second piston 11, so that space in piston cylinder 1 increases or reduces, first piston at this time
2 distances for being moved to second piston 11 increase, therefore distance increases accordingly when the first 7 reset movement of pressure spring, to realize the first pressure
Spring 7 can guarantee in compression the pressing force of left and right so that anaesthetic smoothly stable can be extruded out of piston cylinder 1, so
The fixed position in the left end of first pressure spring 7 need to move left and right cooperate second piston 11 to move left and right so as to cause piston cylinder 1
Interior spatial variations.
Since the left end of the first pressure spring 7 is contacted with the right end end face of spool gear 6, by stirring thumb wheel, the rotation band of thumb wheel
It moves first gear 8 to rotate, first gear 8 engages spool gear 6 and rotates, and spool gear 6 rotates so that before and after on the first male-pipe 5
It is mobile, to realize the movement to the left end of the first pressure spring 7.
After operation more than completion, it is inserted into the position that patient needs to anaesthetize through spray head 13, pulls driving lever 20, driving lever 20 at this time
Upper end be moved to the left to through the first rectangular channel 21 drive guide rod 17 move right, guide rod 17 moves right to third pressure spring 24
The trend and elastic potential energy of rebound are compressed and are made it have, while the right end of guide rod 17 squeezes the through-hole of 9 lower end of wedge block
16, and be pressed down against under the action of 17 right end inclined-plane of guide rod through wedge block 9, so that the upper end of wedge block 9 is detached from groove
10, be detached from moment realize that the anaesthetic of piston cylinder 1 is squeezed under the reset response of the first pressure spring 7, thus realize anaesthetic from
Spray head 13 sprays, and first piston 2 moves right in the process, when the right end of first piston 2 passes through inlet by inlet
It is blocked, with persistently moving to right for first piston 2, when arc panel 3 moves to inlet, arc panel 3 continues to seal inlet
It is stifled, realize that inlet is by sealed condition always in 2 extrusion process of first piston.
The significant benefit of the present apparatus: the present apparatus stores medical fluid by moving left and right second piston 11 to realize in piston cylinder 1
Capacity converts to meet the needs of different patients are to different medical fluids, simultaneously as mobile second piston 11 makes in piston cylinder 1
Volume change so as to cause the first pressure spring 7 reset distance change, due to the first pressure spring 7 reset distance increase will lead to extruding after
The insufficient pressure when phase, therefore the left end fixed point of the first pressure spring 7 is subjected to corresponding change to guarantee when increasing 1 volume of piston cylinder
First pressure spring 7 still is able to meet the lasting extrusion to its inside anaesthetic, so that the present apparatus is more efficient and rational when in use.
The utility model is novel, clever structure, practical, by adjusting second piston come regulating piston cylinder body
Product, so that the capacity for realizing that anaesthetic rifle once sprays is adjustable；The first pressure spring fixed bit is adjusted after completing piston cylinder volume and adjusting
It sets to meet the anaesthetic in the piston cylinder after volume tune and remain to stable be forced out.
