Abstract
The utility model relates to a breath sensor which is composed of three conductive electrodes which are insulated mutually and elastic insulated materials which are filled among the electrodes. The utility model can obtain the relevant information generated in the process of breath by the mutual position variation among the electrodes. The utility model has high detection sensitivity and anti-jamming ability, without disturbing the natural breath process. The utility model is widely used for monitoring a baby's breath, people's breath obstacle in sleeping, and the critical patients. The utility model can become a new breath sensor applied to the clinic medicine and the home health. Meanwhile, the utility model can be used for the breath monitoring operation in the physiology, the medicine research, and the special operating environment, and becomes a universal sensor for obtaining the breath signal.
Description
The invention belongs to the medical monitoring checkout gear, be specifically related to a kind of pick off with electronics method monitoring respiratory.
The pick off that is used for Respiratory Care at present has four classes.The first kind adopts heat sensitive sensor detecting breathing air-flow, obtains the signal of telecommunication relevant with respiratory.Second class adopts thoracic impedance variation in the electrode detector respiratory, obtains associated electrical signals.The 3rd class adopts the elastoresistance band that ties up to breast abdominal part periphery, obtains the resistance change signal relevant with respiratory.The 4th class adopts the elasticity inductance band that ties up to breast abdominal part periphery, inspection and the relevant displacement signal of respiratory mesothorax abdomen perimeter change.In actual applications, all there is weak point in aforesaid way.Signal is influenced by ambient temperature easily in first kind device, and the minor variations of sensing station can cause very big error.The second class device can't discern because the invalid breathing that upper respiratory tract obstruction causes.The 3rd class device has very big null offset.The 4th class device is subjected to the electromagnetic interference of environment easily, and is on the low side to the useful signal detection sensitivity simultaneously.
The object of the invention is to propose a kind of new scheme at above-mentioned four kinds of defectives that device exists in Respiratory Care, and is sensitive, monitor respiratory accurately, easily, answers the need of clinical medicine treatment monitoring and family health care.
Help to illustrate that sketch map of the present invention is as follows.
Fig. 1. electric capacity respiration pickup structure.(1)-and conductive electrode, (2)-conductive electrode, (3)-conductive electrode, (4)-rubber-like insulant, (5)-circuit board, (6)-and lead, (7)-lead, (8)-dc source, (9)-insulating barrier, (10)-and insulating barrier, (11)-lead, (12)-lead, (13)-lead.
Fig. 2. there is the electric capacity respiration pickup of soft bag shape sheath the outside.
(14)-softish bag shape sheath.
Capacitor breathsensor is by conductive electrode (1), (2) of three mutual insulatings (3) and be filled in and have flexible insulating materials (4) and directly between (1) and (2) Circuit board (5) and the lead (6) that links to each other with (5) with (1), (2), (3) binding (7) consist of with the dc source (8) that links to each other with (5). Electrode (1), (2), (3) Be that the metal forming of 0.01MM-1.0MM is made by thickness, or made by wire netting, or Made by conductive rubber. Be filled in and have flexible insulation material between (1) and (2) Material is chemical synthetic fiber. Be filled between (1) and (2) and have flexible insulation Material thickness is between 0.5MM-100MM. (1) and (2) by insulating barrier (9) and (10) contact with conductive electrode (3). Conductive electrode (3) cover conductive electrode (1), (2) and have flexible insulating materials (4) and insulating barrier (9), (10) outside. Electricity Link between road plate (5) and conductive electrode (1), (2), (3) lead (11), (12), (13) length is between 1MM-100MM. In (1), (2), (3), (4) outside The bag shape sheath that a softness is arranged is from each of outer protection capacitor breathsensor Part.
Electric capacity respiration pickup of the present invention detects the radial displacement relevant with respiratory, by the variation generation signal of telecommunication relevant with respiratory of distance between conductive electrode (1) and (2), by lead (6), (7) output.Have very high detection sensitivity, good capacity of resisting disturbance, very little to splanchnocoel pressure, not disturbance general breathing process, output is the signal of telecommunication that almost concerns with the splanchnocoel volume-variation.Be widely used in the infant breathes monitoring, critical patient's Respiratory Care, the sleep-respiratory monitoring, general breath signal source becomes the novel respiration pickup of a class that is applied to clinical medicine and family health care.
