Embodiment 15
Medicine dissolving device as described above, the present embodiment are that rubber plug therein is described.
The inner wall of syringe, cross-sectional shape be it is uncertain, can be adjusted according to the case where practical application.Having
In the use process of body, in order to easy to process, syringe is generally pylindrical, and the cross section of inner wall is generally circular in cross section.The application
In, for the ease of embodiment is described, in the case where not illustrated, it is equal to default related syringe inner wall
For circle.But this does not represent the application and discloses only syringe cross section of inboard wall as circular shape, but by taking circle as an example,
The explanation of progress；When syringe inner wall is other shapes, can also be expanded according to situation described in this application, for example,
" diameter " of wherein rubber plug etc. is expanded as " size " etc..
As shown in Figure 12 and Figure 13,
A kind of rubber plug comprising piston 1 and piston support 2, the piston 1 and piston support 2 combine；Wherein, the work
The diameter of plug 1 is greater than/is less than the diameter of piston support 2.
In this way, when rubber plug is placed on inside medicine dissolving device, in piston 1 and piston support 2, the side that is only relatively large in diameter with it is molten
The inner wall of medicine device syringe 3 contacts, so that the contact area of rubber plug and 3 inner wall of syringe is small, the resistance that rubber plug is subject to when sliding is smaller.
In this way, the resistance that rubber plug is subject to when moving is small, rubber plug is driven to move back and forth the active force needed by pneumatic mode
It is smaller, so that the pressure for generating the gas of the active force is smaller, and then set to generating active force or compression, transmitting gas
The requirement of standby gas tightness also reduces；In this manner it is possible to increase the service life of equipment, the cost of equipment is reduced, with
And increase the applicability of equipment.
Embodiment 16
Rubber plug as described above, the present embodiment are different from place and are, as shown in figure 13, piston support 2 it is straight
Diameter is greater than the diameter of the piston 1.
In this way, only piston support 2 is contacted with the inner wall of medicine dissolving device syringe 3 when rubber plug is placed on inside medicine dissolving device, so that
The contact area of rubber plug and 3 inner wall of syringe is small, and the resistance that rubber plug is subject to when sliding is smaller.
In this way, the resistance that rubber plug is subject to when moving is small, rubber plug is driven to move back and forth the active force needed by pneumatic mode
It is smaller, so that the pressure for generating the gas of the active force is smaller, and then set to generating active force or compression, transmitting gas
The requirement of standby gas tightness also reduces；In this manner it is possible to increase the service life of equipment, the cost of equipment is reduced, with
And increase the applicability of equipment.
The piston 1 has jack 11, and the piston support 2 has plug 21, and the plug 21 is inserted into the jack 11,
The piston 1 and piston support 2 are combined.In this way, the plug 21 of the piston support 2 is inserted into the jack of the piston 1
In 11, it that is to say in insertion piston 1, play a supporting role to piston 1；Wherein, piston 1 is soft material composition, and elasticity is good, easily
Deformation occurs；Piston support 2 is constituted for hard material, is not susceptible to deformation, is played a supportive role.
Wherein, the material of the piston support 2 is plastics, in this way, it is at low cost, it is easy to process.
Embodiment 17
Rubber plug as described above, the present embodiment are different from place and are that as shown in figure 14,1 diameter of piston is slightly
2 diameters are supportted less than the piston, in this way, the piston supports 2 sides and the needle when rubber plug is assembled in medicine dissolving device syringe 3
Cylinder 3 inner walls fitting, the piston 1 have gap with 3 inner wall of syringe.
In this way, piston support 2 is bonded with 3 inner wall of syringe when driving the medicine dissolving device by pneumatic mode, reach close
Seal effect；In this way, syringe 3 is divided into former and later two spaces by piston support 2, it is fitted in syringe 3 between two spaces by piston support 2
It is sealed on wall；When being driven, it is washed into gas in the space at 3 rear portion of syringe, so that the air pressure in the space rises, from
And piston support 2 is driven to move forward (piston 1 also while moving forward), by the air or liquid in the space of 3 front of syringe
It squeezes out；Or the gas in the space at 3 rear portion of syringe is extracted, so that the air pressure in the space declines, lower than 3 front of syringe
Air pressure in space, piston support 2 moves backward (piston 1 also while moving forward) under the action of draught head, by outside air
Or liquid is pumped into the space of 3 front of syringe.
Wherein, the piston 1 has gap with 3 inner wall of syringe, in this way, the posture of rubber plug can be controlled,
Preventing piston support 2 from deflecting under the influence of air pressure, (once piston support 2 slightly deflects, the side of piston 1 will be with needle
3 inner walls of cylinder abut against, so that the deflection can not formally occur, would not also generate gap, and sealing can still be kept to imitate
Fruit).(in the case where piston support 2 is circular situation, if piston support 2 is rotated around one of diameter, this creates the terminal
Deflection, so that occurring gap between piston support 2 and 3 inner wall of syringe, being unable to reach the effect of sealing.)
Embodiment 18
Rubber plug as described above, the present embodiment are different from place and are, as shown in figure 15, the size of the piston 1
Slightly larger than the size that the piston supports 2 plugs 21, for wrapping up the plug 21 of piston support 2.In this way, the size of piston 1 is much smaller than
The size of piston support 2 is mainly used for wrapping up the plug 21 that piston supports 2, to prevent the plug 21 of piston support 2 from connecing with medical fluid
Touching, piston support on 2 plug 21, generally rough shape, the hiding bacterium having in large quantity of air are easy, if do not lived
