Description
Technical field
This utility model belongs to the gastrointestinal tract sampling equipment on the biologic medical, is specifically related to a kind of assimilating type gastrointestinal tract sampling microcapsule.
Background technology
Gastroenteropathy is a kind of common disease, and the main foundation of the diagnosis of gastroenteropathy at present is gastroscopy.Though gastroscopy can provide morphologic basis preferably, but medically can cause bleeding, the pathological changes of morphological change such as ulcer, swollen thing may for optimum, also may be for pernicious; lesion nature may for inflammatory disorders, also may be for malignant tumor etc., therefore lack the formulation that observation that biopsy draws materials can influence correct diagnosis and therapeutic scheme.Up to now, the gastric juice sampling all is in traditional interpolation type gastroscopy process clinically, extract a certain amount of gastric juice, and the sampling of intestinal juice just can't realize at all, and this is the difficult problem of puzzlement medical profession always.In recent years, because the fast development of MEMS science, the application of MEMS on biomedicine also obtained substantial progress.Because traditional interpolation type gastroscopy meeting brings very big misery to patient, and the trend that is replaced by the wireless capsule scope has been arranged.
The utility model content
The purpose of this utility model is to provide a kind of assimilating type gastrointestinal tract sampling microcapsule, it is simple in structure, reliable, control is convenient, draw Digestive system by physisorption, not only can not bring misery, and can guarantee the capacity of the Digestive system of absorption to the patient, can be by the external remote control device to human body alimentary canal location sampling, for the diagnosis of digestive tract disease provides more definite evidence.
Assimilating type gastrointestinal tract sampling microcapsule of the present utility model comprises microcapsule and remote control unit, microcapsule contains: adsorbing fiber, electromagnetic actuator device, power supply, magnetic switch, shell and sampling aperture, adsorbing fiber is in the front position in the shell, electromagnetic actuator device is in the middle section position in the shell, and power supply and magnetic switch are in the back-end location in the shell; The solenoid of described electromagnetic actuator device is connected with power supply, and power supply is connected with magnetic switch; A sampling aperture is arranged on the described shell, and the circumferential baffle plate by electromagnetic actuator device of sampling aperture blocks; The closure and the disconnection of described remote control unit control magnetic switch.
Described electromagnetic actuator device is made up of baffle plate, back-moving spring, armature, iron core, bobbin and solenoid, is with bobbin on the rear end of armature and the iron core, is wound with solenoid on the bobbin; Gapped between armature and the iron core, armature can move forward and backward, and iron core is fixed on the bobbin, and bobbin is fixed on the outer casing inner wall; The armature front end is fixed with baffle plate, and baffle plate can be with back-moving spring along with armature axially-movable together on the armature, and an end of back-moving spring is fixed on the baffle plate, and the other end is fixed on the bobbin.
Before magnetic switch is connected, back-moving spring is in free state, when remote control unit control magnetic switch and after it is connected, the electromagnetic force that electromagnetic actuator device produces makes iron core attractive to armature, because iron core is fixed on the bobbin, bobbin is fixed on the outer casing inner wall, and armature just is driven like this, the drive baffle plate back extreme direction in shell together axially moves, and back-moving spring is compressed.The baffle plate motion makes the sampling aperture open, and adsorbing fiber expands simultaneously, and adsorbing fiber just can be drawn to Digestive system like this, by the uptake that can control Digestive system turn-on time of control magnetic switch.
Described solenoid is the solenoid type solenoid, and bobbin is for falling " worker " font.
Described sampling aperture is taper sampling aperture, and is big more the closer to the outer surface of outer cover cross-sectional area, is easy to draw Digestive system like this.
In addition, this utility model is shorter sample time, adopts common button cell can meet the demands as power supply.
This utility model compared with prior art has following advantage and beneficial effect:
1) electromagnetic actuator device of the present utility model is simple in structure, and is reliable, and control is convenient feasible, and is very favourable to the volume microminiaturization of whole device;
2) this utility model relies on the physics hygroscopic effect of adsorbing fiber to draw Digestive system, not only can not bring misery to the patient, and can guarantee the capacity of the Digestive system of absorption;
3) remote control unit of the present utility model can be in the keying of the power supply of external control microcapsule, thereby realizes microcapsule location sampling in vivo.
