Abstract
It is not fixed firmly and leans on for solution electrocardiogram test instrument top electrode, the problem of being easy to fall off, the present invention provides a kind of electrocardiogram test instrument electrode fixing devices, including the air bag being connected with the electrode on conducting wire, it is characterized in that, it further include the tensile axis being connected to above air bag, for fixing the fixed ring of tensile axis above air bag, the air bag includes the air bag internal layer that air bag outer layer and variable volume degree are greater than air bag outer layer, closed first chamber is formed between the gentle intracapsular layer of air bag outer layer, air bag internal layer lower part contacts closed for second chamber with application on human skin, the tensile axis and air bag internal layer are tightly connected and air bag internal layer can be pulled to generate volume change, the tensile axis is equipped with the groove cooperated with fixed ring.
Description
Technical field
Invention is related to field of medical device, in particular to a kind of electrocardiogram test instrument electrode fixing device.
Background technique
Electrocardiogram test instrument is the detection common equipment and instrument of cardiac problems, and general electrocardiogram test instrument is solid using single layer air bag
It is scheduled on the skin of human chest, but due to testee's height is fat or thin or dry skin etc. is different, leads to air bag
Fixation is not sufficiently stable, and is often fallen off.
Summary of the invention
It leans on, be easy to fall off to solve the problems, such as that electrocardiogram test instrument top electrode is not fixed firmly, invention provides a kind of electrocardio and surveys
Instrument electrode fixing device is tried, the technical solution adopted is as follows:
A kind of electrocardiogram test instrument electrode fixing device, including the air bag being connected with the electrode on conducting wire, which is characterized in that also
Including being connected to tensile axis above air bag, above air bag for fixing the fixed ring of tensile axis, the air bag includes gas
Capsule outer layer and variable volume degree are greater than the air bag internal layer of air bag outer layer, are formed between the gentle intracapsular layer of air bag outer layer close
The first chamber closed, air bag internal layer lower part contact closed for second chamber, the tensile axis and air bag internal layer with application on human skin
It is tightly connected and air bag internal layer can be pulled to generate volume change, the tensile axis is equipped with the groove cooperated with fixed ring.
After air bag is contacted with human skin, air bag internal layer is driven by pulling up tensile axis, to make second chamber
Volume becomes larger, and first chamber volume becomes smaller, therefore second chamber pressure becomes smaller, and first chamber pressure becomes larger, pressure between the two
Strong official post obtains air bag and skin is fixed more firm firm.
Further, the air bag outer layer and stretching shaft connection place are equipped with sealing ring.
Advantageous effect of the invention is: can stablize electrode by this fixation device and fix, reduce the hair of obscission
It is raw, meanwhile, the position of tensile axis can be fixed by fixed ring, facilitate operation.
Detailed description of the invention
Fig. 1 is the fixed device overall structure diagram of electrocardiogram test instrument
Wherein, 1- tensile axis, 2- fixed ring, 3- air bag outer layer, 4- air bag internal layer, 5- first chamber, 6- second chamber,
7- sealing ring.
With reference to the accompanying drawing 1 and embodiment invention is described in further detail.
A kind of electrocardiogram test instrument electrode fixing device as shown in Figure 1, including the gas being connected with the electrode on conducting wire
Capsule, which is characterized in that further include be connected to tensile axis 1 above air bag, above air bag for fixing the fixation of tensile axis 1
Ring 2, the air bag include the air bag internal layer 4 that air bag outer layer 3 and variable volume degree are greater than air bag outer layer 3, outside the air bag
Closed first chamber 5 is formed between 3 gentle intracapsular layer 4 of layer, it is second that 4 lower part of air bag internal layer contacts closed with application on human skin
Chamber 6, the tensile axis 1 are tightly connected with air bag internal layer 4 and air bag internal layer 4 can be pulled to generate volume change, the stretching
Axis 1 be equipped with fix 2 rings cooperation groove.
In the present embodiment, sealing ring 7 is additionally provided on the outside of tensile axis 1 and air bag outer layer 2 for sealing outside tensile axis 1 and air bag
Gap between layer 2, prevents gas leak.
In fixed electrode process, after electrode and skin closure, second chamber 6 forms closed space, at this point, outward
It pulls tensile axis 1 that 4 volume of air bag internal layer is driven to become larger, also results in 3 volume of air bag outer layer and become smaller, so as to cause first chamber
Pressure becomes larger, and the pressure side of second chamber is small, and inside under the action of outer pressure difference, air bag is whole more firm with skin fixation,
After skin is fixed in conjunction with air bag, the position of tensile axis 1 is fixed using fixed ring 2, it is multiple to guarantee that tensile axis 1 will not generate
Position.
Described above is only the preferred embodiment of invention, it should be pointed out that: for those skilled in the art
For, under the premise of not departing from inventive principle, several improvement can also be made, these improvement also should be regarded as the protection model of invention
It encloses.
