Embodiment 1:
In Fig. 2; A kind of microsample valve is equipped with valve core rod 502 in the valve body 501, valve core rod 502 upper ends are provided with the upper valve core 505 that is sealed and matched with upper valve base 504; Valve core rod 502 lower ends are provided with the bottom spool 509 that is sealed and matched with lower valve base 510, and spring 506 also is installed on the valve core rod 502.Spring 506 in this example makes upper valve core 505 and upper valve base 504 be in normally off, and user is the patient of row anesthesia postoperative xerostomia for example, through the mode of sucking; Then to overcome spring force descending for upper valve core 505; Open between spool 505 and the upper valve base 504, this moment can liquid make-up, but as continue to suck; Then form between bottom spool 509 and the lower valve base 510 and be sealed and matched; Need stop to suck the back and wait to suck once more behind the valve core reset and could continue liquid make-up, thereby realize micro-controllably liquid make-up, even and if microsample valve deviate from also and can not pollute sheet.In this example with moisturizing profit lip but the patient who is not suitable for a large amount of moisturizings again is an example; But the device in this example also can be used for the treatment of comfort type; For example replenish milk or a spot of liquid glucose to baby; Also need can be used to the some diseases of slow release treatment, for example need the oral ulcer of slow release treatment etc.
Embodiment 2:
Shown in Fig. 3, Fig. 4; A kind of microsample valve is equipped with valve core rod 502 in the valve body 501, valve core rod 502 upper ends are provided with the upper valve core 505 that is sealed and matched with upper valve base 504; Valve core rod 502 lower ends are provided with the bottom spool 509 that is sealed and matched with lower valve base 510, and spring 506 also is installed on the valve core rod 502.Position near lower valve base 510 on valve body 501 is provided with flexible bags 511; Be provided with a plurality of chutes 508 on the valve body 501 in flexible bags 511; Strut 512 is installed in the chute 508; Strut 512 lower ends are connected with chute 508 lower ends or flexible bags 511, and the other end passes through block 507 or directly is connected with valve core rod 502.
Be normally off between described lower valve base 510 and the bottom spool 509.
In this example, by the structure of flexible bags 511 and strut 512, thereby the microsample valve in this example can have the more control mode.For example, through backing down bottom spool 509, can open the sealing between lower valve base 510 and the bottom spool 509,504 formation are sealed and matched with upper valve base to drive upper valve core 505 until valve core rod 502.Thereby realize micro-liquid make-up.The perhaps mode through sucking is shunk flexible bags 511, and it is up then to make strut 512 push valve core rod 502, thereby opens the sealing between lower valve base 510 and the bottom spool 509, drives upper valve cores 505 until valve core rod 502 and forms with upper valve base 504 and be sealed and matched.Thereby the microsample valve in this example has more purposes; For example can be used for needs according to continuing to change the occasion of also constantly exerting pressure liquid make-up for flexible bags 511 with changing; The slow release treatment in the motion for example is in case this external pressure stops or excessive then valve is ended.
By lower valve base 510 is normally closed structure, normally closed thus structure, the pressure of spring make between lower valve base 510 and the bottom spool 509 for being sealed and matched, can be used in the application of pressure-bearing, for example externally be positioned at elevatedly, be used for the container of storaging liquid.
In this example; Also adopted the design of lower valve base 510 internal diameters greater than upper valve base 504 internal diameters, the benefit of this design is to back down easily bottom spool 509 being applied to some special occasions, and because upper valve base 504 internal diameters are less; Controlled the flow of liquid, to realize trace circulation.Guide holder 503 can make the operation of valve core rod 502 more smooth-going.
