Description
Technical field:
The present invention relates to Non-invasive intracranial pressure detector after a kind of hand-held decompressive craniectomy, belong to biomedical pressures detection field.
Background technology:
The clinical meaning detecting intracranial pressure after decompressive craniectomy is can observe therapeutic effect, judging prognosis, instruct anaphase.The technology detecting intracranial pressure at present is clinically divided into wound and the large class of noinvasive two.There is wound technical risk large, expensive.Atraumatic technique mainly contains: 1. retinal venous pressure or tremulous pulse platen press, 2. flash visual evoked potential method, 3. tympanum displacement method, 4. transcranial Doppler sonography method, 5. particular acupoint method etc.The shortcoming that these methods mainly exist: mostly 1. be indirect inspection, measurement error is comparatively large, and 2. need specific apparatus, survey bureau is greatly sex-limited, 3. repeatable poor.Therefore, be necessary to develop a kind of safety, moderate, reliability is high, limitation is little, the simple Non-invasive intracranial pressure detector of favorable repeatability, structure.
By literature search, the relevant open report of the measuring device identical with technical solution of the present invention is not found.
Summary of the invention:
The object of the invention is to the deficiency overcoming existing noninvasive detection device, Non-invasive intracranial pressure detector after a kind of hand-held decompressive craniectomy is provided.
Non-invasive intracranial pressure detector after hand-held decompressive craniectomy of the present invention; by protecting sheathing (1); be placed in the flexible measuring interface (2) of protecting sheathing (1) bottom; be placed in the measuring cell (3) on flexible measuring interface (2); be embedded in the battery handle (4) in protecting sheathing (1) outside; be placed in its in handle (4) built with the signal processing circuit board chamber (5) of signal processing circuit, be embedded in display screen (6) composition of protecting sheathing (1) top.Wherein, measuring cell (3) is that 3 acceleration transducers be equidistantly placed on flexible measuring interface (2) are formed.
During detection; the acceleration transducer be equidistantly placed on compliant interface (2) by 3 detects 3 groups of signals; after the isolation filter on signal processing circuit board, amplifying circuit process; compared by comparison circuit; converted accordingly by translation circuit again, then corresponding result is transferred to display screen (6) display being embedded in protecting sheathing (1) top.Isolation filter circuit, amplifying circuit, comparison circuit, translation circuit are controlled by the microcontroller on signal processing circuit board.Acceleration transducer (3), signal processing circuit board and display screen (6) are by the cell powers be contained on handle (4).
The device that the present invention selects market to buy is made according to a conventional method.
The invention has the advantages that: structure is simple, esy to use, safe and reliable, repeatable high, it is directly measured effectively can improve certainty of measurement.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is schematic block circuit diagram of the present invention.
Detailed description of the invention:
As shown in Figure 1; the checkout gear of Noninvasive intracranial pressure after hand-held decompressive craniectomy of the present invention; by protecting sheathing 1; be placed in the flexible measuring interface 2 bottom protecting sheathing 1; be placed in the measuring cell 3 on flexible measuring interface 2; be embedded in the battery handle 4 outside protecting sheathing 1, be placed in its in handle 4 built with the signal processing circuit board chamber 5 of signal processing circuit, the display screen 6 be embedded in above protecting sheathing 1 forms.Wherein, measuring cell 3 is that 3 acceleration transducers be equidistantly placed on flexible measuring interface 2 are formed.
In Fig. 2 schematic block circuit diagram; 3 acceleration transducers be equidistantly placed on compliant interface 2 detect 3 groups of signals; 3 groups of signals are after the isolation filter on signal processing circuit board, amplifying circuit process; enter comparison circuit to compare; then converted accordingly by translation circuit, be finally transferred to the display screen 6 be embedded in above protecting sheathing 1 and show.Microcontroller on signal processing circuit board controls the isolation filter circuit on signal processing circuit board, amplifying circuit, comparison circuit, translation circuit.Power supply provides electric energy to acceleration transducer, signal processing circuit board and display screen.
This device is as follows for detecting the process of intracranial pressure after decompressive craniectomy:
According to the situation of experimenter, embodiment is divided three classes:
1, postoperative Consciousness: experimenter gets clinostatism, the hand-held handle 4 of tester, the detection position of compliant interface 2 towards experimenter is put down naturally, compliant interface 2 and experimenter are detected after position touches, require experimenter's nictation, the pressure change of nictation is transmitted to the detection position of scalp surface, this signal detected by acceleration transducer 3, shown by display screen 6 after signal processing circuit process, namely complete one-time detection.
2, consciously postoperative but handicapped: experimenter gets clinostatism, the hand-held handle 4 of tester, the detection position of compliant interface 2 towards experimenter is put down naturally, compliant interface 2 and experimenter are detected after position touches, require that experimenter opens eyes, the pressure change of eye opening is transmitted to the detection position of scalp surface, this signal detected by acceleration transducer 3, shown by display screen 6 after signal processing circuit process, namely complete one-time detection.
3, postoperative unconscious: experimenter to be held in the position that tester requires, the hand-held handle 4 of tester one, the detection position of compliant interface 2 towards experimenter is put down naturally, compliant interface 2 and experimenter are detected after position touches, with another hands pressing detection position, consequent pressure change is transmitted to the detection position of scalp surface, this signal detected by acceleration transducer 3, shown by display screen 6 after signal processing circuit process, namely complete one-time detection.
