Specific embodiment
Presently in connection with attached drawing, the present invention is described in detail.This figure is simplified schematic diagram, is only illustrated in a schematic way
Basic structure of the invention, therefore it only shows the composition relevant to the invention.
This application involves a kind of security protection pin electrode, which generally comprises grip part 3, protection department 9, needle-shaped electricity
Pole 4 and conducting wire；Wherein, the tail end of needle electrode 4 is arranged on grip part 3 and is electrically connected with conducting wire, which is mainly used for
Operator is hand-held to be held, and concrete shape can according to need selection, as long as can be held；It needle electrode therein and leads
Line can use needle electrode in the prior art and conducting wire, and the application has no excessive limitation, the other end and electricity of conducting wire to this
The electric signal that the needle electrode for being pierced into patient skin acquires is conveyed to electron detection device by sub- detection device connection, conducting wire.
Protection end in the pin electrode of the application includes that bottom 5, fixed side 6 and elastic sides 1, bottom 5 are usually arranged
There is one, and the bottom 5 and above-mentioned grip part 3 have mutual corresponding face；Elastic sides 1 have under the action of elastic stress
The tendency squeezed to fixed side 6, but elastic sides and fixed side can separate between each other；Fixed side and
Elastic sides can be set to one or more, that is, can have a fixed side and elastic sides cooperation, can also have
There are multiple fixed sides to be used cooperatively respectively with multiple elastic sides, the specific quantity that is arranged can carry out appropriate adjustment.
The application is provided with through-hole 10 in the bottom of protection department 9, should be by passing through for needle electrode 4, the head of needle electrode
End penetrates protection department across the through-hole 10 and is pierced by from the edge of the fixation side of protection department, and the tail end of needle electrode is fixed on
It on holding end, and is electrically connected with conducting wire, the head end of needle electrode 4 has run through entire protection department 9, and the head end of needle electrode 4
Top, i.e., the tip of entire needle electrode 4 have passed through protection department 9 and expose in the outside of protection department 9.When in use, expose
The skin that stylus electrode tip outside is pierced into patient detects, and user is the piercing that hand-held grip part 3 carries out pin electrode 4
Movement.
The needle electrode of the application is pierced by from the edge of the fixation side of protection department 9, that is, needle electrode position at this time
In the centre of fixed side and elastic sides, due to the oriented fixed extruding of side 6 under the action of elastic stress of elastic sides 1
Tendency, therefore, needle electrode 4 is resisted against on the fixed side by the elastic sides of the application protection department 9, that is, elastic sides
Elastic force needle electrode is pressed against on fixed side.It is mentioned here against or be pressed against there is no by needle electrode it is completely solid
Surely be pressed against on fixed side, even be pressed against or against state, needle electrode 4 equally can be in fixed side 6
It is slided between elastic sides 1, that is, needle electrode 4 still can be held 3 drive of end in this case and complete out needle and receipts
The movement of needle.In order to obtain this elastic force, it can also be provided with spring 7 before elastic sides and bottom, with the elastic force of spring 7
Needle electrode is resisted against on fixed side 6.
Connection can be destroyed between the protection department 9 and grip part 3 of the application, this, which can destroy connection, can use easily broken filament
Or other suitable forms are realized, as long as what both be can be realized destroys connection, and without concrete restriction, herein can
It destroys connection and refers to that the connection between grip part and protection department is slight, destructible, once this connection status is destroyed,
Originally the grip part and protection department being linked together are split up into two mutually independent parts.
It is provided with connecting line 2 between the protection department and grip part of the application, the effect of this connecting line 2 is limitation protection department
9 and the distance that is separated from each other both after mutual connection is destroyed of grip part 3, so that the two is unlikely to be completely dispersed.
The use process of the application are as follows:
Before use, being in original factory state, protection department and grip part at this time still maintains destructible connection, needle
The tip of shape electrode is passed through between the fixation side of protection department and elastic sides, and operator holds grip part, by needle electrode
Tip be pierced into the skin of patient, the other end of conducting wire is connected into upper electron detection device, to carry out electrode detection.
After the completion of detection, i.e., after use, operator holds grip part, and the tip of needle electrode is pulled out from patient skin
Out, it after tip being extracted, gently exerts oneself, destroys connection between tamper protection portion and grip part, so that grip part and protection
Portion is separated from each other.Operator holds holding end on the other hand, and another hand holds protection end, continues extraction needle electrode outward, needle-shaped
Electrode continues between fixed side and elastic sides to end motion is held, until the point of needle electrode under the action of extraction force
End by elastic sides and fixed side against position, the tip of needle electrode retracts to the inside of protection department at this time, and
Due to losing the undertaking or so of needle electrode main part, elastic sides under the action of elastic force directly tightly the be pressed against it is solid
Determine on side, the space for being originally used for needle electrode sliding is shut completely, needle electrode is completely enclosed within protection department at this time
Inside.Simultaneously as being provided between protection department and grip part with connecting line, this connecting line limits protection department and grip part
Between separated distance, needle electrode will not be made to pull out completely from the inside of protection department, as needed, the length of this connecting line
The generally 30%-70% of needle electrode length, how length of tube is not arranged, and is required to guarantee to be straightened that cut cannot completely in connecting line
When being further continued for elongation, the tip of needle electrode is not pulled out from the inside of protection department.
In order to avoid the tip of needle electrode is pulled out from the inside of protection department, present invention also provides another realities
Apply mode, that is, the lower part of needle electrode head end is provided with flange, the diameter of the flange is greater than the diameter of the through-hole, by
In there are this flanges 8, prevent needle electrode by the through-hole from being drawn out, that is, this flange 8 limits needle electrode
Tip is pulled out from protection department inside.
Since the tip of needle electrode is completely enclosed within inside protection department, it is difficult to touch the external world, therefore, the tip is not
Operator and other related personnel can be stabbed or be stabbed, there is very high safety.
Meanwhile one embodiment as the application, the application can also stick in setting on holding end or protection end
The pin electrode can be pasted directly on the skin of patient by the mucigel, thus eliminate and additionally tape by glue-line
The step of, it operates more easy.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
