Description
Technical field
The present invention relates to connecting and disconnecting, and the device of minipill positioning signal source is provided by power supply in the magnetic field control minipill.The invention belongs to medicine equipment ancillary technique field.
Background technology
Development along with microelectronics, micromachining technology, be used for the mini-medical apparatus of medical diagnosis on disease and disease treatment and the focus that device has become research, the micro device that wherein has a class to be used for disease of digestive tract diagnosis and treatment is called as " minipill ", as wireless endoscope, the miniature drug release device of alimentary canal etc.This minipill all need provide the energy with minicell in inside usually; But, because the restriction of minicell capacity requires ability energized when pill is sent into alimentary canal usually.Aspect switch, all there are big, the baroque deficiency of volume in present existing tongue tube or other magnetic switchs, are difficult to satisfy the requirement of minipill.Therefore, need a kind of microswitch devices that can satisfy minipill.
On the other hand, it is the important step that influences its using value that minipill is accurately located, and this needs to possess positioning signal source in the minipill.If, will increase energy consumption at the inner active positioning signal source (as transmitted radio signal etc.) that uses of minipill; And the magnetic orientation technology is a kind of location technology of maturation, and it provides positioning signal source with permanent magnet, not consumed energy.Therefore, adopting magnetic orientation is one of prioritization scheme of minipill location, main thought is to utilize magnetic field sensor to detect the permanent magnet space magnetic field to distribute, realize magnetic orientation according to magnetic dipole space magnetic field distributed model again, and then reach micro device Kinematic Positioning in the body and follow the tracks of its movement locus.
Summary of the invention
Goal of the invention is at the demand of minipill switch and positioning signal source, the purpose of this invention is to provide a kind of magnetic switch device that is used for the connecting and disconnecting of minipill internal electric source, and utilize this magnetic switch device to provide positioning signal source for the magnetic orientation of minipill.
Technical scheme the invention provides a kind of magnetic switch device that is used for the connecting and disconnecting of minipill internal electric source, partly is made up of action permanent magnet, switch movable contact, lead, the spacing telecontrol equipment of action permanent magnet, controlling magnetic field, power supply and operating circuit etc.The action permanent magnet is positioned at stopping means, relative two sides in its removable space, one side is fixed with power supply, another side is that controlling magnetic field produces the position, the action permanent magnet is fixed with switch movable contact in the pole surface relative with the electromagnetism pole plate of power supply, and switch movable contact and power supply are drawn lead respectively and tapped into operating circuit.
Wherein, controlling magnetic field can adopt permanent magnet, also can adopt hot-wire coil or other that mode of stationary magnetic field can be provided; Its polarity and locus should guarantee that it is opposite to the attraction direction of action permanent magnet to active force and battery pole plates that the action permanent magnet produces, and the intensity in magnetic field should make the action permanent magnet can drive switch contact reliably to break away from battery pole plates.
The action permanent magnet is the positioning signal source of minipill magnetic orientation, and material is ferromagnetic materials such as neodymium iron boron, and shape and size should adapt to the space that minipill is allowed utilization.
Magnetic switch operation principle of the present invention: when no extraneous controlling magnetic field, utilize the power of attracting each other between action permanent magnet and battery pole plates that switch movable contact and battery pole plates are communicated with, switch connection, power supply is powered to minipill; When extraneous controlling magnetic field is arranged, controlling magnetic field produces attraction direction opposite effect power between a direction and action permanent magnet-battery pole plates to the action permanent magnet, make the action permanent magnet drive switch movable contact and break away from battery pole plates, switch disconnects, and battery stops minipill being powered.
Technique effect the invention provides the device that utilizes external magnetic field control minipill internal power switch to be switched on or switched off, its biggest advantage is that the positioning signal source with minipill internal power switch and minipill magnetic orientation combines, solved the mains switch of minipill inside on the one hand, can be when pill be sent into alimentary canal energized, make the additive decrementation of battery in the pill be reduced to minimum; On the other hand, this magnetic switch device has been eliminated because of being positioned at the energy resource consumption of pill inside again for the location of minipill provides positioning signal source.Simultaneously,, also saved volume, reduced because of designing the pill cost of miniature magnetic switch because micro power switch and positioning signal source are united two into one.In addition, adopt the present invention can make the pill assembling simpler, for the practicability and the small lot test manufacture of pill are laid a good foundation.
