Technical field
It is that the purpose that reaches diagnosis is swallowed in animal or human's body that this utility model relates to a kind of, and the sampling apparatus of collection liquid in digestive tract specially refers to a kind of digestive tract sampling apparatus.
Background technology
Liquid in analysis and research human body or the animal alimentary canal can be understood the gastral health status of human body or animal accurately, carries out liquid sample in digestive tract, has important value for gastral metabolism status of research and relevant biochemical characteristic.U.S. Patent Publication is crossed a kind of pill formula sampling apparatus, and this device volume is little, in light weight, sampling convenience, no wound, no pain, no cross infection, and 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 steam vent especially in described device, this steam vent is blocked with 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, the technical scheme that provides a kind of reliability height of sampling, energy expenditure digestive tract low, simple in structure to sample microelectromechanicdevices devices.
The technical solution of the utility model is: the digestive tract sampling apparatus, comprise that body seal connects the back and constitutes enclosed cavity, it is characterized in that the right-hand member of shell is an exhaust end, be provided with exhaust hole, the shell left end is a sampling end, is provided with the sampling through hole, 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, controlling organization is housed in the air bag, actuating unit and removable broken bag apparatus are housed in the hole of controlling organization;
Described controlling organization is that controlling organization comprises heating resistor, power supply and remote-control gear, is provided with at least 1 through hole and is communicated with the air bag on controlling organization both sides on controll block; Described switching mechanism is, connects seal cover at sampling end spring one end, and end is fixedly connected in the sampling through hole in addition, and seal cover is sealed and matched with the sampling through hole, is connected with on the seal cover and flexibly connects line, flexibly connect line in addition end be connected with air bag; Described actuating unit is, on controlling organization, be provided with heating resistor, controlling organization is provided with recessed hole, connect spring in the hole, spring end in addition is connected with removable broken bag apparatus, and spring is provided with fusible broken string, and described removable broken bag apparatus is block, be connected with spring and fusible broken string, left end is provided with sharp object.Described air bag is that softish high resiliency organic material is made.
This utility model is to comprise that the back that is tightly connected constitutes the shell of enclosed cavity, is provided with sampling through hole and the steam vent that is communicated with this cavity at the shell two ends, be provided with controlling organization, actuating unit, removable broken bag apparatus in the capsule and be provided with relatively-movable sharp object, before removable broken bag apparatus motion, fixedly 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, fusible broken string between removable broken bag apparatus and the controlling organization fuses, under the effect of spring, drive removable broken bag apparatus motion, sharp object punctures air bag, air in the air bag is discharged from exhaust hole rapidly, air bag shrinks rapidly, end is because of the rapid contraction generation parital vacuum of air bag in addition to be positioned at the sampling storehouse, and the liquid in the digestive tract is inhaled in 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, the problem that does not exist passage not to be opened, and 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, the also corresponding minimizing of corresponding controlling organization 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, omitted elements such as spring, piston, sealing ring, make structure simpler.
