Abstract
The utility model discloses a diversified capsule type endoscope signal reception antenna, including flexible circuit board, plane helical antenna, signal amplifier, wire, antenna signal selector, the flexible circuit board be divided into four and thickness and be 0.2mm, each flexible circuit board openly all is equipped with 15x15cm's plane helical antenna, each plane helical antenna's positive center all is connected with signal amplifier, signal amplifier comprises the miniaturized circuit board and moulds plastics with low pressure and fix on the helical antenna of plane, four signal amplifier all connect with the wire and put through on the antenna signal selector. Compared with the prior art, the beneficial effect of the utility model: low cost, broadband, increase receiving antenna's gain, small, simple to use, it is convenient to overhaul, not influenced by the human motion and has solved the single shortcoming of signal reception directionality.
Description
Technical field
The utility model relates to medical Instrument field, particularly relates to a kind of multi-faceted capsule endoscopic signal receiving antenna.
Background technology
Capsule endoscopic is taken pictures in human body by microcam, and view data is launched in body through coding radio signal.Externally receive viewdata signal by reception antenna, and through demodulation, decoded back view data, finally carry out process by the software systems of specialty and diagnose.
Capsule endoscopic transmitting in human body is weak, and signal is large through the decay of tissue, and cause external Signal reception unstable, the error rate is high; And capsule moves in vivo and do not have rule, sense is poor.The aerial array that existing highly sensitive external reception antenna is made up of the antenna of multiple lump shape, or adopt disposable can arbitrarily bioadhesive patch sensing probe composition aerial array.But these two kinds of modes affect by human motion and the directivity of Received signal strength is single, and cost is high, inconvenient maintenance.
Utility model content
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of low cost, broadband, the gain of increase reception antenna, volume is little, use is simple, maintenance multi-faceted capsule endoscopic signal receiving antenna easily.
for achieving the above object, the technical solution of the utility model is:a kind of multi-faceted capsule endoscopic signal receiving antenna, comprise flexible PCB, flat helical antenna, signal amplifier, wire, aerial signal selector, described flexible PCB is divided into four pieces and thickness is 0.2mm, each block flexible PCB front is equipped with the flat helical antenna of 15x15cm, the center of each flat helical antenna is all connected with signal amplifier, signal amplifier is made up of minitype circuit board and is fixed on flat helical antenna with low-pressure injection molding, and four block signal amplifiers all connect with wire and are switched on aerial signal selector.
As preferably, the signal reception of described flexible PCB is unaffected when bending 120 ° arbitrarily.
As preferably, described flat helical antenna is made of copper.
As preferably, be connected and fixed with low-pressure injection molding between described aerial signal selector and wire.
compared with prior art, the beneficial effects of the utility model:low cost, broadband, the gain of increase reception antenna, volume is little, use is simple, and maintenance is convenient, does not affect by human motion and solves the single shortcoming of Signal reception directivity.
Accompanying drawing explanation
fig. 1 is front view of the present utility model.
Embodiment
As shown in Figure 1, a kind of multi-faceted capsule endoscopic signal receiving antenna, comprise flexible PCB 1, flat helical antenna 2, signal amplifier 3, wire 4, aerial signal selector 5, described flexible PCB 1 is divided into four pieces and thickness is 0.2mm, each block flexible PCB 1 front is equipped with the flat helical antenna 2 of 15x15cm, the center of each flat helical antenna 2 is all connected with signal amplifier 3, signal amplifier 3 is made up of minitype circuit board and is fixed on flat helical antenna 2 with low-pressure injection molding, four block signal amplifiers 3 all connect with wire 4 and are switched on aerial signal selector 5.The signal reception of described flexible PCB 1 is unaffected when bending arbitrarily 120 °.Described flat helical antenna 2 is made of copper.Be connected and fixed with low-pressure injection molding between described aerial signal selector 5 and wire 4.Flexible PCB 1 of the present utility model is respectively used to cover human body surrounding, flat helical antenna 2 is for receiving the signal of the capsule endoscope in human body, and flat helical antenna 2 can receive multi-band signal, even if capsule endoscope towards at people's variation in vivo, appoint and can receive its signal sent, solve the restriction of single antenna directivity, and the signal reception of flexible PCB 1 is unaffected when bending arbitrarily 120 °, even if carrier is kept in motion also do not affect the reception of signal, the signal that flat helical antenna 2 receives is amplified by signal amplifier 3, flat helical antenna 2 signal strength signal intensity of which position is differentiated again best by aerial signal selector 5, select the signal in this direction of continuous reception again, between flat helical antenna 2 and signal amplifier 3, between signal amplifier 3 and wire 4, fix with low-pressure injection molding between wire 4 and aerial signal selector 5, make each parts stable connection, four pieces of flexible PCBs 1 are provided separately, make convenient maintenance and replacement.The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection range of the present utility model.
