Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of hand-held probe that is used for impedance or resistance detection.
Background technology
Measuring bio-impedance, resistance or current potential all needs to use electrode, and in order to form the loop, electrode has two usually, one of them conductive area is bigger, is fixed on organism body surface somewhere, often is called reference electrode, another is placed on needs sites measured, often is called exploring electrode.The relevant patent of existing exploring electrode need be fixed on organism surface by adhesive tape mostly, the electrical quantity that detects a series of positions if desired is then quite loaded down with trivial details, as the novel a kind of acquiring biological electric signals electrode ZL00244894.7 of practicality, a kind of body surface bio electricity of utility model detecting electrode ZL 92242524.8.Also have in actual the use and use sucker to fix exploring electrode, but sucker is all opaque, be not easy sucker is fixed on accurately on the position, organism surface is a lot of local uneven in addition, be not suitable for sucker and fix.The medical exploring electrode terminal 96249238.8 of utility model can detect the electrical quantity of finger position easily by a finger ring, but finger ring will be pointed both sides and link together by the finger ring that conducts electricity, sometimes need to detect respectively the electrical quantity of finger both sides, finger ring is just no longer suitable.
Summary of the invention
The purpose of this utility model is to provide a kind of hand-held probe that is used for impedance or resistance detection, and the head of metallic conductor is equipped with cylindric sponge or the foam that has adsorbed conducting liquid in its ingredient, for the detection of the signal of telecommunication provides cushioning effect.When the reference electrode that is fixed on the organism body surface that this utility model and have big conductive area is used, when hand-held probe contact organism, a loop can be formed between reference electrode and the hand-held probe, thereby impedance, the resistance of organism can be measured.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: it comprises metallic conductor, sponge, insulating sleeve, insulation crust.The cylindrical metal conductor forms through bending, short end of metallic conductor links to each other with the sponge of absorption conducting liquid, insulating sleeve is enclosed within outside metallic conductor short a section and the sponge, insulation crust is enclosed within metallic conductor a section than length, the sweep that metallic conductor is insulated outside sleeve and the insulation crust covering covers insulating paint or cabinet, be positioned at the long end of metallic conductor of insulation crust, draw with lead.
The useful effect that the utlity model has is: it is suitable for hand-held the use, is used to measure bio-impedance, resistance; Electrode has a handle, and handle top also has a pit, is fit to thumb or forefinger and is placed on that counter electrode applies certain strength or obtains certain hands sense on the pit; The head of electrode is equipped with cylindric sponge or the foam that has adsorbed conducting liquid, for the detection of the signal of telecommunication provides cushioning effect.
Description of drawings
Fig. 1 is a structural principle cutaway view of the present utility model;
Fig. 2 is the vertical view of this utility model Fig. 1.
Among the figure: 1, metallic conductor, 2, sponge, 3, insulating sleeve, 4, insulation crust, 5, screw, 6, nut, 7, conducting terminal, 8, lead.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As accompanying drawing 1, shown in Figure 2, comprise metallic conductor 1, sponge 2, insulating sleeve 3, insulation crust 4, screw 5, nut 6, conducting terminal 7, lead 8.Cylindrical metal conductor 1 forms through bending, short end of metallic conductor 1 links to each other with the sponge 2 of absorption conducting liquid, insulating sleeve 3 is enclosed within outside metallic conductor 1 short a section and the sponge 2, insulation crust 4 is enclosed within metallic conductor 1 a section than length, the sweep that metallic conductor 1 is insulated outside sleeve 3 and insulation crust 4 coverings covers insulating paint or cabinet, be positioned at the long end of metallic conductor 1 of insulation crust 4, draw with lead 8.
The outside that described metallic conductor 1 is insulated the sweep outside sleeve 3 and insulation crust 4 coverings has the pit that can let go and refer to.
Angle between the part of described cylindrical metal conductor 1 bending is 90-180 °.
During use, to be fixed on the testee body surface and connect relevant checkout equipment with the supporting reference electrode of this electrode, to fill in the insulating sleeve again behind a certain amount of conducting liquid of sponge taking-up absorption, the tester holds the insulation crust of hand-held probe, forefinger or thumb are placed on metallic conductor knee recess top, resistance or impedance that the position that hand-held probe sponge and testee need be tested contacts and just can measure this position.
The above-mentioned specific embodiment is used for this utility model of explaining; rather than this utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to this utility model is made all fall into protection domain of the present utility model.
