Abstract
The utility model belongs to the technical field of electromagnetic sensors and relates to a patient respiratory rhythm monitoring device based on an electromagnetic sensor. The monitoring device comprises the electromagnetic sensor and an inductance measuring meter, wherein the electromagnetic sensor adopts a coil, which is shaped like the periphery of a gear and is formed in a manner that a conducting wire is coiled into a circle; and two terminals of the coil are connected with the input terminal of the inductance measuring meter. The sensor is fixed at the chest of a human body; and with the expansion and contraction of the chest muscles during respiration, the sensor expands and contracts, so as to reflect the respiratory rhythm of the human body to be detected from the measured inductance value. The utility model further provides a monitoring device adopting a gear-shaped hollow core as the electromagnetic sensor. The utility model has simple structure and low cost, and is sensitive, quick and efficient in detection.
Description
Technical field
This utility model belongs to the electromagnetic transducer technical field, relates to patient respiration rhythm and pace of moving things monitoring device.
Background technology
Under normal person's quiescent condition, the rhythm and pace of moving things of breathing is even and neat substantially.Under the pathological state, tend to occur the variation of various respiratory rhythms.Breathing under the pathological state comprises that Cheyne-Stokes respiration, meningitic breathing, inhibition are breathed and the sample of sighing is breathed, and they can show visibly different respiratory rhythm, thereby can judge the residing pathological state of patient according to different respiratory rhythms.
Present stage China's patient respiration rhythm and pace of moving things monitoring technology along with the aggravation of progress of science and technology and economic globalization process, China has obtained in respiratory rhythm Study on Monitoring Technology and application facet and has developed rapidly.Monitoring technology trends towards high-techization, seriation, tachymeter, portability day by day.
At present, the domestic respiratory variations that can monitor patient with AUTOMATIC MONITOR OF RESPIRATORY RHYTHM, but this type of cost is higher, and the checkout gear complexity.
The utility model content
The purpose of this utility model provides a kind of patient respiration rhythm and pace of moving things monitoring device simple in structure, with low cost.This utility model adopts following technical scheme:
A kind of patient respiration rhythm and pace of moving things monitoring device based on electromagnetic transducer, comprise the electromagnetic transducer, the inductance measuring meter that are used to place the human body front, the coil as outer peripheral gear shape of described electromagnetic transducer for being made around a circle by a conductor loop, two terminals of coil link to each other with the input of inductance measuring meter.
Monitoring device of the present utility model, coil preferably can stretch; Its diameter is between 10-100mm.
This utility model provides a kind of patient respiration rhythm and pace of moving things monitoring device based on electromagnetic transducer with identical inventive concept simultaneously, comprise the electromagnetic transducer, the inductance measuring meter that are used to place the human body front, described electromagnetic transducer comprises that a periphery is the hollow of gear shape, be wound with at least one turn coil along the gear shape periphery thereon, two terminals of coil link to each other with the input of inductance measuring meter.
Monitoring device of the present utility model, the hollow of described gear shape hollow for stretching; Coil diameter is 10-100mm, and number of turns is between 1-20000.
The monitoring device of the patient respiration rhythm and pace of moving things of electromagnetic transducer according to claim 1 is characterized in that the diameter of coiling is between 0.001mm-10mm
Patient respiration rhythm and pace of moving things monitoring device of the present utility model, pick off is made of the gear shape coil, can stretch, during use, be placed on the patient front, because the expansion and the contraction of chest muscle cause the expansion and the contraction of pick off, thereby are reflected the rhythm and pace of moving things of tested human body respiration by the inductance value that records when breathing.Has advantage simple in structure, with low cost, highly sensitive.
Description of drawings
Fig. 1 is the monitoring device structured flowchart of the patient respiration rhythm and pace of moving things based on electromagnetic transducer of the present utility model.
Specific implementation method
Below in conjunction with drawings and Examples this utility model is elaborated.
Embodiment 1
Fig. 1 is the measuring device structured flowchart that draws according to embodiment of this utility model.It is made of electromagnetic transducer 1,2 two major parts of inductance measuring meter.Electromagnetic transducer 1 is the coil that is enclosed the likeness in form outer peripheral gear that forms by the lead system of holding, and two terminals links to each other with the input of inductance measuring meter.Because the character of lead itself, coil can outwards or inwardly stretch.
Electromagnetic transducer 1 is the coil of similar gear-like, and this coil is a hollow, and its manufacture method is that coiling forms on the hollow that a gear shape can be stretched.Hollow can by the soft or hard appropriateness can figuration again can abduction or in the material of nylon, rubber of contracting and so on make.Also can be made by duroplasts, each turning point (position 3) bottom profile of tooth is by two sections hinged forming of plastics.The coil diameter of this electromagnetic transducer is 10-100mm, and number of turns can be between 1-20000; The diameter of coiling can be between 0.001mm-10mm.
Measurement of mutual inductance instrument 2 can use commercial electric impedance analyzer (for example Agilent 4284, homemade measurement of mutual inductance instrument etc.); During measurement, this type of electromagnetic transducer can be positioned over the chest of human body to be measured, two terminals of coil link to each other with the input of inductance measuring meter, judge by the inductance value that measures whether patient's to be measured respiratory rhythm is stable.By experiment or emulation, according to the chest muscle expansion and the size of shrinking, measure the different induction value of this pick off, make a healthy table by demarcation, when the inductance value that records was in dangerous scope, inductance measuring meter was reported to the police.
Measuring method specifically may further comprise the steps:
(1) this type of electromagnetic transducer is positioned over the breast portion of human body to be measured;
(2) inductance value of measurement electromagnetic transducer;
Inductance measuring meter judges according to the data that measure whether patient's respiratory rhythm is in the middle of the danger, the data of storing in the inductance measuring meter can be by experiment or emulation obtain.
