Description
Technical field:
This utility model relates to a kind of sampling apparatus of swallowing, and specially refers to a kind of sampling apparatus swallowed of pill formula, is used for collection liquid in the digestive tract of animal or human's body.
Background technology:
U.S. Pat 5395366 discloses a kind of pill formula sampling apparatus, comprise that a sampling storehouse that is used for store sampled liquid, piston that is used to produce parital vacuum, one are used for the spring of driven plunger motion, a controlling organization that is used for the control piston motion, this device is used at the animal alimentary canal collection liquid.This device utilizes the energy drives piston of compression spring, and piston moves to the other end from the end that the sampling storehouse has one-way valve, and the liquid outside the parital vacuum that produces when motion will install sucks the sampling storehouse.This device has the following disadvantages: at first, the maximum shortcoming of described device is a complex structure.Because this device utilizes the motion of piston to produce parital vacuum and samples, piston is to an end motion time, must discharge gas, therefore design a steam vent especially in described device, this steam vent is blocked with a departing stopper, when sampling, piston utilizes air pressure that stopper is extruded, when action is carried out, if stopper can not break away from, then can't sample, reliability reduces.In addition, utilize the thrust of spring to make the piston motion, for overcome friction and air discharge etc., need bigger power to drive, the driving mechanism that control energy is big is controlled in requisition for consuming more energy, the controlling organization of described device needs bigger electric current to control, and has also increased the volume of controlling organization when increasing energy.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reliability height of sampling, the energy expenditure miniature sampling apparatus of digestive tract suction-type low, simple in structure are provided.
The technical solution of the utility model be this device comprise the back that is tightly connected constitute the shell of enclosed cavity, hole, controlling organization, actuating unit, the movable mechanism that is communicated with this cavity respectively arranged on the outer casing end and be fixed on outer casing end on the relative movable mechanism of through hole on sharp object, before the movable mechanism motion, movable mechanism is fixedlyed connected with controlling organization; In the cavity of shell, air bag is housed, inlet end at air bag has the open pore that is communicated with and stretches out air bag with air bag, sealing-plug is arranged in the hole, after in the air bag controlling organization being housed, inwall interference fits with shell, actuating unit and movable mechanism are housed in the hole of controlling organization, on controlling organization, have through hole to be communicated with, on the through hole of the sampling end of shell, have out or airtight mechanism with the air bag on controlling organization both sides.
Work process of the present utility model is as follows: after air bag is inflated fully, this device is swallowed digestive tract, controlling organization is after receiving the control signal that begins to sample, the fixedlying connected between movable mechanism and the controlling organization of breaking, actuating unit drives the movable mechanism motion, the sharp object that is fixed on the movable mechanism relative with through hole on the outer casing end punctures air bag, air in the air bag is discharged from the through hole of an end rapidly, air bag shrinks rapidly, the rapid contraction that is positioned at the air bag of sampling storehouse one end produces parital vacuum, is arranged in the outer liquid of device and is inhaled into the sampling storehouse.
This utility model compared with prior art has following technique effect:
1, sampling reliability height.Because air bag is discharged gas from being punctured, this gas is directly discharged from through hole, does not have ventilation
The problem that the hole can not be opened, reliability is improved.
2, energy expenditure is low.Puncture the needed power of air bag and be far smaller than the needed power of driven plunger, corresponding control
The also corresponding minimizing of mechanism's energy needed.
3, simple in structure.Owing to utilize the contraction of air bag to replace the motion of piston, can avoid complicated piston mechanism design,
Omit elements such as spring, piston, sealing ring, made structure simpler.
