Other are similar to Fig. 3 or close, and for example the shape area of multiple electrodes piece composition is not comprising any one skull suture in cranium brain
Situation of half or the shape of more than half etc. is belonged to, distribution shape and the measurand of the electrode slice in the fixing band
In the range of the shape of at least one skull suture on skull is not matched that.
In addition, as shown in figure 4, in the application other embodiments, fixing device 10 can include：First fixing band, 11 He
Second fixing band 12, wherein, the description of the first fixing band 11 can be found in the description in the last period in detail, and the second fixing band 12 is half
Ring-type, and the two ends of the second fixing band 12 are each attached in the first fixing band 11, and the fixation at the two ends of the second fixing band 12
Position is located at both sides relative in the first fixing band 11 respectively.
In the embodiment of the present application, several electrode slices can be provided with the second fixing band 12, it is also possible to be not provided with
Whether electrode slice, specifically arranged, can unrestricted choice according to actual needs.When electrode slice is provided with the second fixing band 12,
The distribution shape of the electrode slice in the distribution shape of the electrode slice in the second fixing band 12 and the first fixing band 11 is differed, i.e., often
The distribution shape of the electrode slice in bar fixing band shape phase respectively from the different skull suture on the skull of the measurand
Matching.Wherein, the situation description of the mating shapes is referring particularly to above-mentioned situation about showing such as Fig. 2.
In disclosure other embodiments, according to actual needs, fixing device 10 can also include more fixing devices,
But it is connected between a plurality of fixing band, forms the space of a skull that can accommodate the measurand.
In addition, in order to improve the comfortableness when wearing, aforementioned all fixing bands can be elastic webbing, so use
When, the electrode slice on the inside of fixing band can be caused to be in close contact with the skin of measurand.
In the disclosed embodiments, electrode slice 20 can be mutually fixed with fixing band in the way of selecting to paste, it is also possible to selected
The mode of suture is sewn to electrode slice 20 in fixing band.
The fixing device that the embodiment of the present disclosure is provided when in use, fixing band can be fixed to the skull of measurand
On, and several electrode slices in fixing band are fitted with skull suture, and the position of the two arrays of electrodes piece in fixing band 11
Put and can fit with the squamous suture of people respectively.
When some electrode slice in fixing band is used as emitter stage, electricity can be launched into skull by skull suture
Magnetostatic wave signal, when some electrode slice in fixing band is used as receiving pole, can be received in skull by skull suture and be passed
Defeated electromagnetic wave signal.
As the main load unit of skull suture is collagen fiber, the bony structures of skull are compared, skull suture is to electromagnetic wave
The degree that obstruction degree is hindered to electromagnetic wave less than skull.So, when some electrode slice in fixing band is made as emitter stage
Used time, the electromagnetic wave signal intensity entered in cranial cavity after transmitting are larger；When some electrode slice in fixing band is used as receiving pole
During use, the electromagnetic wave signal intensity sent from cranial cavity is received larger.
Therefore, when the detection means is for detecting to cerebral edema, the electromagnetic wave signal for detecting is stronger, and then makes
The result that measured according to electromagnetic wave signal accurately, can really react the situation of intracranial edema.
On the basis of said apparatus embodiment, the embodiment of the present disclosure additionally provides a kind of cerebral edema signal detecting method.
As shown in figure 5, the method is comprised the following steps：
Step S101：By at least one electrode slice on the first predeterminated position in aforementioned cerebral edema signal supervisory instrument and electricity
Magnetostatic wave signal discharger is connected.
First predeterminated position is the transmitting position in the detection means, before the step is carried out, can be by the first default position
The all electrode slices put are connected by controlling switch with electromagnetic wave signal discharger, and then in this step, Ke Yitong
Cross controlling switch at least one electrode slice on the first predeterminated position is connected with electromagnetic wave signal discharger.
Step S102：By at least one electrode slice on the second predeterminated position in the cerebral edema signal supervisory instrument and electricity
Magnetostatic wave signal reception device is connected.
Second predeterminated position is the receiving position in the detection means, in the same manner, before the step is carried out, can be pre- by second
If all electrode slices on position are connected by controlling switch with electromagnetic wave signals receiver, and then in this step, can
At least one electrode slice on the second predeterminated position to be connected with electromagnetic wave signals receiver by controlling switch.
Step S103：Control the electromagnetic wave signal discharger to launch on the electrode slice on first predeterminated position
Electromagnetic wave.
Due to the shape of a skull suture on the distribution shape of the electrode slice in fixing band and the skull of the measurand
Shape matches, so when detection means is worn on the head of measurand, can pass through to adjust the position of detection means
So that the position of the electrode slice of the first predeterminated position is corresponding with the position of a skull suture on the skull of measurand, you can
So that the position of the line of the central point of multiple electrodes piece is located in skull suture, and then electrode slice is fitted in along skull suture
On the skin of measurand.
As the main load unit of skull suture is collagen fiber, the bony structures of skull are compared, skull suture is to electromagnetic wave
The degree that obstruction degree is hindered to electromagnetic wave less than skull.So, when the electrode slice on the first predeterminated position is taken as emitter stage
During use, the electromagnetic wave signal intensity entered in cranial cavity after transmitting is larger.
Step S104：Control to receive on electrode slice of the electromagnetic wave signals receiver from second predeterminated position
Electromagnetic wave.
In the same manner, when the electrode slice on the second predeterminated position is taken as receiving pole to be used, receive what is sent from cranial cavity
Electromagnetic wave signal intensity is larger.
Therefore, when being detected to cerebral edema using the method, the electromagnetic wave signal for detecting is stronger, and then causes root
The result measured according to electromagnetic wave signal is accurate, can really react the situation of intracranial edema.
The above is only the specific embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
