Description
Technical field
The present invention relates to capsule endoscope technical fields, and in particular to a kind of sampling system based on needle tubing and vacuum technique
System.
Background technique
Before the present invention proposes, the Chinese invention patent of Publication No. CN 1820798A " release by capsule type digestive tract medicine
Put and sampling apparatus ", disclose a kind of using spring while the capsule system that is sampled and released the drug, in the design, utilize bullet
Spring pushes piston motion to generate temporary low pressure, sucks extraneous air-liquid from thieff hatch by pressure difference.Thieff hatch is a kind of " introversive
Check valve ", sampling front and back is closed state.The deficiency of the design is: sampling pool independence and integrality are insufficient.
The Chinese patent " digestive canal sampler " of 201453300 U of Publication No. CN, discloses a kind of adopting for pneumatic type
Sample capsule system.After the system is triggered, fuse easy fuse release spring, and thimble is pushed to puncture air bag.Air bag is deflated from the right
Gas vent sprays.Deflated balloon, the contraction process of left end air bag generate low pressure and absorb body fluid by thieff hatch.It is arranged at thief hatch
There is switch, by plug, spring and filament composition.Before sampling, plug is in the open state under the elastic force effect of spring, filament pine
It relaxes.During sampling carries out, air bag pulls filament constantly to the right, and gradually filament is straightened.Filament overcomes spring, pulls plug, will
Thieff hatch is blocked, and sampling terminates.This design uses pneumatic mode, and triggering is completed by spring.The design has the disadvantage that: the
One, sampling pool is sealed by the air bag of expansion before sampling, but actually air bag can still be contacted with the external world.Second, before sampling terminates
Plug is in pop-up state, is unfavorable for the intake and movement of capsule.
