Description

One utilizes single-chip microcomputer to monitor breathing equipment

Technical field

This utility model relates to one and utilizes single-chip microcomputer to monitor breathing equipment, relates to health care and health care field.

Background technology

Life is to breathe, and monitoring is breathed significant, very necessary.From detecting the methods of breathing, sound collector (mike) can be utilized to detect respiratory air flow, also can detect according to nasal cavity air pressure during breathing and humiture change, even judge breath state by arteriopalmus situation and blood containing indirect means such as oxygen analyses, relevant product is quite a few.But all there is many drawbacks, otherwise affect greatly by outside environmental elements, precision is low, False Rate is high, or device complicated, bulky, wear inconvenience.Hospital uses respirator usually, puts on breathing mask to patient, and this device is expensive, carry inconvenience, also needs to wear breathing mask, allow people feel stifling, very uncomfortable, and inconvenience is turned round, and is therefore difficult to promote the use of outside hospital.

Utility model content

This utility model is that one utilizes single-chip microcomputer to monitor breathing equipment, primarily of wire, circular foil member, cylinder blanket, fixed support, oval head clip, and single-chip microcomputer, buzzing, infrared transmitting tube, wireless module, power supply composition, whole device volume is little, can be worn on before nostril.

The technical solution of the utility model is: by a thin hard straight wire, (mutually touching conducting) is passed from the center of a circular foil member, two bottom center positions of a cylinder blanket are fixed at two ends, wherein wire is drawn in one end, cylinder blanket side-closed, two bottom surface air-flows are unimpeded, bore is similar to nostril size, 2 bottom center's points are all connected with cylinder blanket insulant, circular foil member diameter is less than the diameter of cylinder blanket, its edge and cylinder blanket inwall leave gap, air-flow can pass through, circular foil member can not be stuck, and weight comparatively I be free to slide along thin hard straight wire along with respiratory air flow.3 wire insulant are separately had to be fixed on cylinder blanket one bottom surface, lead-in wire is left in outside, three ends in inner side determine a plane, parallel with cylinder blanket bottom surface, three ends are touched in the same side and stop circular foil member, the insulant that opposite side is connected with cylinder blanket by another bottom center's point of cylinder blanket stops, circular foil member is limited between cylinder blanket one bottom surface and above-mentioned three end place planes.When circular foil member slidably reciprocates by air-flow drive, through the thin hard change that directly will be turned on or off wire and another three wires at sheet metal center.

In actual applications, for monitoring the respiratory air flow in user two nostril simultaneously, two said apparatus can be fixed together by connection bracket parallel connection, four wire correspondences of being drawn respectively by two devices connect, form four groups of wires, wherein will be connected to power electrode through this group wire of circular foil member center, another three components does not connect single-chip processor i/o port, just can monitor respiratory air flow, according to pre-set programs, also signal can be sent by support circuit, such as when time-out breathing is more than 10 seconds, or when there is asphyxia continuously, sound immediately, light alarm, or it is infrared, wireless signal such as grade.Meanwhile, respectively in the outside of whole device fix an oval head clip, when conveniently wearing, be clipped in both sides, nostril.

The beneficial effects of the utility model are, direct-detection respiratory air flow, methodological science, precisely reliable, and device is simple, with low cost, small volume, wear conveniently, and the suitability is strong, comfortableness good.

Detailed description of the invention

By a thin hard straight wire (1.), pass from the center of a circular foil member (2.), two bottom surfaces of a cylinder blanket (3.) are fixed on (4. in two ends, 5.) central point, wherein bottom surface 1(is 4.) one end extraction wire, the side-closed of cylinder blanket (3.), two bottom surfaces (4., 5.) air-flow is unimpeded, central point all insulate with cylinder blanket (3.) and is connected, circular foil member (2.) is relatively little, edge and cylinder blanket (3.) side inner walls leave gap, its weight comparatively I is free to slide along thin hard straight wire (1.) along with respiratory air flow.4. another 3 wires (6., 7., 8.) are fixed on enclosure bottom 1() central point is connected on insulant with cylinder blanket, these 3 wires extend to inside respectively but do not pass circular foil member (2.), three ends (A, B, C) determine a plane, with cylinder blanket bottom surface 2(5.) parallel, and can touch, stop that circular foil member (2.) is slided, opposite side is by cylinder blanket bottom surface 2(5.) insulant that is connected with cylinder blanket of central point stops, circular foil member (2.) can only be slided between this two plane.For improving device sensitivity, circular foil member (2.) sliding stroke should be limited in less scope, equidistant best results between three ends (A, B, C).

For while monitoring user two nostrils respiratory air flow, can be fixing by connection bracket (10.) parallel connection by two said apparatus, two devices draw four wires respectively, one to one after corresponding connection, again by four groups of conductor wire end (o, a, b, c) be connected to power electrode and single-chip processor i/o port respectively, as required can series resistance.When circular foil member (2.) slidably reciprocates in process by air-flow drive, the thin hard change be directly turned on or off between wire (1.) and another three wires (6., 7., 8.) will be made.With single-chip microcomputer monitoring o and a, o and b, break-make change between o and c, just can determine whether respiratory air flow, perform pre-set programs, also can be sounded by support circuit, light alarm, wireless signal.

Wearing for convenience, respectively in the outside of two devices fixing an oval head clip (9.), for being clipped in both sides, nostril.
