Description
Technical field:
This utility model relates to a kind of miniature releasing device of swallowing, and specially refers to the miniature releasing device of swallowing of a kind of pill formula, is used for the digestive tract h substance at animal or human's body, as medicine or food or label.
Background technology:
A kind of device at digestive tract assigned address h substance has been proposed in U.S. Pat 4425117, this device is divided into two cells, a movable mechanism that can move under the pressure effect of compression spring is arranged in first Room, a pin is arranged in the movable mechanism end; Second cell be around foraminate medicine holding bin, drug pack is put into medicine holding bin in tiny balloons; Being equipped with a fixed dam in the interposition of this device separates two cells.When this device arrives the digestive tract assigned address, the external world sends electromagnetic wave signal, be arranged in the coil and the oscillating circuit induction outer signals of this device case and produce faradic current, release movement is triggered by institute's faradic current, movable mechanism travels forward under the spring pressure effect, and at certain position, the broken baffle plate of acupuncture also punctures the balloon that medicine is housed, under the contraction of balloon, drug release.There is following shortcoming in this device, and at first, the release of medicine depends on the aperture that balloon is broken by acupuncture, if balloon interior pressure is big inadequately, then drug releasing rate is slower; Secondly, the passage that medicine discharges in install is the aperture on the shell circumferential wall, medicine discharges the leakage that depends on aperture from medicine holding bin, and these apertures may be blocked by the material in the digestive tract, do not have suitable impressed pressure, medicine might can't go out by small hole leaking, when particularly the outer wall of medicine holding bin closely contacts with digestive tract, medicinal liquid may can only discharge in the storage warehouse, discharges not thorough; In addition, because the release channel of described device is the aperture on the shell circumferential wall, owing to have aperture on the shell wall, coil in the housing can only twine at an end of shell, the coiling length of coil is short, and inductive effects is poor, the signal coupling efficiency is low, causes the reliability of controlling organization low.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of miniature releasing device of swallowing thorough, simple in structure fast that discharges is provided.
In order to realize the purpose of above-mentioned utility model, the technical solution of the utility model is that this device comprises the shell that is tightly connected, controlling organization is housed in the cavity that shell constitutes, by the movable mechanism of controlling organization control, drive actuating unit, the storage capsule of movable mechanism motion, the hole that is communicated with cavity is arranged on the shell end relative with storage capsule, before the h substance, movable mechanism is fixedlyed connected with controlling organization; In the cavity between controlling organization and the piston position-limit mechanism is arranged, actuating unit and controlling organization end in contact, movable mechanism is housed on the actuating unit, piston is contained between position-limit mechanism and the storage capsule, with piston area be fixed with sharp object on the right movable mechanism, during material in discharging storage capsule, the fixedlying connected between movable mechanism and the controlling organization of breaking, actuating unit drives movable mechanism to storage vessel motions, sharp object punctures piston and storage capsule, and movable mechanism and piston seal compress.
Work process of the present utility model is as follows: controlling organization is after receiving control signal, controlling organization disconnect with movable mechanism between fixedly connected, the actuating unit that drives the movable mechanism motion is started working, movable mechanism under the driving of actuating unit to the storage capsule end motion, sharp object continues to puncture storage capsule after puncturing piston, the material rapid release under the effect of the elastic contractile force of storage capsule that is encapsulated in the storage capsule comes out, movable mechanism promotes piston and moves forward under the effect of actuating unit, d/d material discharges by the through hole that is positioned at the outer casing bottom end.
This utility model compared with prior art has following technique effect:
1, discharges fast thoroughly.In this utility model, after sharp object punctures storage capsule, d/d material rapid release under the effect of the elastic contractile force of storage capsule comes out, movable mechanism promotes piston and moves forward, under the promotion of piston, d/d material discharges by the through hole that is positioned at outer casing bottom, discharges thoroughly.
2, simple in structure.Because the spacer between storage capsule and the sharp object is a piston rather than the fixing baffle plate of isolating, the piston assembling is more simple, and piston also has the function that the promotion material is discharged.
