In order to realize that wedge block 10 can be moved downward and can be resetted upwards, the lower part of 1 cylinder wall of piston cylinder is equipped with one
A vertical through slot, wedge block 10 are placed in through slot, and the lower half portion of wedge block 10 stretches out the outside of piston cylinder 1 and is equipped with one
Horizontal through-hole 18,18 side of through-hole left side are equipped with a guide rod 19 that can be moved left and right, and the right end of guide rod 19 is wedge shape, guide rod 19
Moving right can be achieved in its wedge-shaped part insertion through-hole 18 and wedge block 10 is moved down, and the bottom of wedge block 10 is equipped with can
Make the second pressure spring 20 that it is resetted upwards.
For convenience of the operation of the present apparatus, the outside of the guide rod 19 is equipped with shell 21, and the lower end of shell 21 is hinged with one
Driving lever 22, the upper end of driving lever 22 are placed in lower end in shell 21 and stretch out shell 21, and the left side of guide rod 19 is equipped with the first of lower ending opening
Rectangular channel 23, the upper end of driving lever 22 are placed in the first rectangular channel 23, and the second rectangular channel 24 of lower ending opening is equipped on the left of guide rod 19,
A support rod 25 that is vertical and being fixed on shell 21, the second rectangle left cell wall and support rod are equipped in second rectangular channel 24
It is equipped with third pressure spring 26 between 25, can realize that 22 upper end of driving lever drives guide rod 19 to move right and press by stirring 22 lower end of driving lever
The trend that tight third pressure spring 26 resets it can flexible potential energy.
In order to realize that second piston 12 can be moved left and right and can be fixed, the right end of the second piston 12 is coaxially fixed with outer
Screwed pipe 27, the right part of piston cylinder 1 are fixed with block plate 28, and 27 spinning of male-pipe is on block plate 28, and perfusion tube 13 is through outer
Screwed pipe 27 is protruded into piston cylinder 1 by the spinning of male-pipe 27 and block plate 28 so that can adjust second piston 12 through screw thread
Length, to adjust each spray value.
For the ease of observing 1 capacity of piston cylinder, the piston cylinder 1 can be set to transparence, and in the cylinder body of piston cylinder 1
Upper setting graduation mark facilitates observation.
The specific work process of the utility model is: the anaesthetic being already equipped with is mounted in bottle simultaneously by the present apparatus when in use
It is mounted at inlet, needs to move left and right second piston 12 according to patient at this time, pass through when automatic second piston 12 in left and right
The realization of male-pipe 27 is screwed, the screw thread on male-pipe 27 and block plate 28 will be moved into properly under itself self-locking
The second piston 12 of position is fixed.
It pulls piston rod 4 that first pressure spring 6 is compressed to left end at this time and makes it have the trend elastic potential energy of rebound,
While pulling piston cylinder 1 first piston 2 is moved to the left, then this process piston cylinder 1 squeezes wedge block 10 and makes it downwards
Mobile, wedge block 10 squeezes the second pressure spring 20 and makes it have the trend and elastic potential energy of rebound during this, when piston cylinder 1 is transported
Move that wedge block 10 launches under the action of the bounce of the second pressure spring 20 into groove 11 when corresponding with 10 pairs of wedge block to groove 11
It realizes the fixation to piston cylinder 1, makes the right side of first piston 2 be moved to inlet when groove 11 and the cooperation of wedge block 10
Left side at this point, anaesthetic can flow into piston cylinder 1 through inlet, piston cylinder 1 is not able to rotate, and can pass through conventional sliding slot and sliding block
Cooperation is to realize.
Due to moving left and right for second piston 12, so that space in piston cylinder 1 increases or reduces, first piston at this time
2 distances for being moved to second piston 12 increase, therefore distance increases accordingly when the first 6 reset movement of pressure spring, to realize the first pressure
Spring 6 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 6 need to move left and right cooperate second piston 12 to move left and right so as to cause piston cylinder 1
Interior spatial variations.
Since the left end of the first pressure spring 6 is contacted with the right end end face of disk 5, make the top on turntable 8 by rotating turntable 8
Bar 9 squeezes the edge cam 7 on disk 5, and mandril 9 squeezes disk 5 while sliding in the cambered surface of edge cam 7, so that circle
Disk 5 moves right, and needs to extract inserted link 17 out of turntable 8 blind hole 16 before rotating turntable 8, when rotation turntable 8 moves
The fixation realized to turntable 8 is reinserted in the blind hole 16 on 8 corresponding position of turntable through inserted link 17 after to suitable position.
After operation more than completion, it is inserted into the position that patient needs to anaesthetize through spray head 14, pull driving lever 22 at this time is to dial
The upper end of bar 22 is moved to the left to drive guide rod 19 to move right through the first rectangular channel 23, and guide rod 19 moves right to third pressure
Spring 26 is compressed and is made it have the trend and elastic potential energy of rebound, while the right end of guide rod 19 squeezes 10 lower end of wedge block
Through-hole 18, and be pressed down against under the action of 19 right end inclined-plane of guide rod through wedge block 10, so that the upper end of wedge block 10 is de-
From groove 11, realize that the anaesthetic of piston cylinder 1 is squeezed under the reset response of the first pressure spring 6 in disengaging moment, to realize
Anaesthetic is sprayed from spray head 14, and first piston 2 moves right in the process, will when the right end of first piston 2 passes through inlet
Inlet is blocked, with persistently moving to right for first piston 2, when arc panel 3 move to inlet be arc panel 3 continue by into
Liquid mouth blocks, and realizes 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 12 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 12 makes in piston cylinder 1
Volume change so as to cause the first pressure spring 6 reset distance change, due to the first pressure spring 6 reset distance increase will lead to extruding after
The insufficient pressure when phase, therefore the left end fixed point of the first pressure spring 6 is subjected to corresponding change to guarantee when increasing 1 volume of piston cylinder
First pressure spring 6 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.
