The specific embodiment
Below in conjunction with specific embodiment, illustrate, but therefore do not limit protection scope of the present invention.
Embodiment mono-:
As depicted in figs. 1 and 2, the embodiment of the present invention provides a kind of electrode retaining collar for Breast electrical impedance fault imaging, comprise insulation shell 1, be distributed in the electrod-array 2 of insulation shell 1 and be arranged at the circuit board 4 in insulation shell 1, described electrod-array 2 is connected with described circuit board 4, described circuit board 4 is provided with joint 5 that just can be for convenience detach without aid, that is to say and can be connected with external equipment is detachable, the size that detects position according to patient's chest with handled easily person is changed electrode retaining collar.For example: described joint 5 can be the REDEL P of lemo company series Self-locking connector.
Described insulation shell 1 comprises circular shell 11 and the handle 12 being made into integration with described circular shell 11.In the present embodiment, being shaped as of circular shell 11 is circular, but in addition can make as required shape conversion.By handle 12, be convenient to user and operate, improved application flexibility.Described joint 5 is installed on described handle 12 ends, and this joint 5 can make user according to the size of patient's chest, change flexibly the electrode retaining collar of different size.
Shown in Fig. 3, described electrod-array 2 consists of 16 electrodes 21 that are distributed in circular shell 11.And the medial wall of described circular shell 11 is distributed with a plurality of fairleads 111, fairlead 111, except be convenient to go between 3 connection electrode 21 and circuit board 4, also has when adhesive electrode is on the circular shell 11 of insulation shell 1 and plays the role of positioning.As shown in Figure 4, described electrode 21 is arc-shaped flaky electrode, and is pasted on the circular shell 11 at fairlead 111 places, guarantees that the lead-in wire 3 being connected with described circuit board 2 is fully in electrical contact simultaneously.
As shown in Figure 5, integrated for the electrod-array 2 of signals collecting and excitation, the difference amplifier 8 being connected with described electrod-array 2 by switch a6, the current source 9 being connected with described electrod-array 2 by switch b7 and the acquired signal of transmitting described difference amplifier 8 with control the joint 5 of the pumping signal of current source 9 on described circuit board 4.That is to say that described switch a6, switch b7, difference amplifier 8, current source 9 and joint 5 are integrated on circuit board 4.By joint 5, be connected with main frame 10, this main frame 10 cuts out and processes acquired signal with gauge tap a6 and switch b7's.For the ease of circuit board 4, install and facilitate circuit trace, the shape of described circuit board 4 is similar to the shape of insulation shell 1, the length requirement of lead-in wire 3 that simultaneously also makes to be integrated in 21, each device on circuit board 4 and electrode is shorter, thus the impact between the spuious circuit of the system that greatly reduces.
In the present embodiment, described switch a6 and switch b7 are multiselect switch.And described electrode retaining collar by switch a6 and switch b7 respectively signals collecting and the signal of control electrode array 2 encourage, wherein switch a6 is connected with difference amplifier 8, switch b7 is connected with current source 9; Acquired signal is exported by joint 5 by difference amplifier 8, and current source 9 is also connected with joint 5.
The use procedure of electrode retaining collar described in the embodiment of the present invention is briefly as follows: first according to custodial person's udder size, select electrode retaining collar, then by joint 5 and external equipment as: main frame 10 is connected, cover is put on measurand breast again, user operating host 10 starts gauge tap a6 and closing of switch b7 carried out signals collecting and excitation, thus acquired signal rear and joint 5 outputs by difference amplifier 8.
Embodiment bis-:
As shown in Figure 6 and Figure 7, the embodiment of the present invention provides the difference of the technical scheme described in a kind of electrode retaining collar for Breast electrical impedance fault imaging and the embodiment of the present invention one to be: the medial wall of described circular shell 11 be distributed with a plurality of openings 111 ', described electrode 21 is for there being the pellet electrode of radian, and by described opening 111 ' be fixed on described circuit board 4.And other structures are all identical with embodiment mono-, do not repeat them here.
In the present embodiment, the medial wall of described circular shell 11 be distributed with a plurality of openings 111 ', described electrode 21 is by described opening 111 ' be welded on described circuit board 4, effective like this impact of having avoided the spuious circuit of system that causes because of lead-in wire.
As shown in Figure 8, the one side that described electrode 21 contacts with measurand is arcwall face, be horizontal plane, and the length of the Length Ratio horizontal plane of its arcwall face is long away from the one side of measurand.Therefore, the pellet electrode that electrode in the present embodiment 21 adopts be shaped as prismatoid, to play the fixedly position-limiting action between electrode 21 and circular shell 11.
Foregoing is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
