Description
Technical field
The present invention relates to Blood pressure monitor, relate in particular to a kind of dust arrester and method of Blood pressure monitor.
Background technology
Monitor is patient care equipment conventional in medical institutions, the vital sign that this equipment can real-time monitoring patient, once that patient vital signs occurs is abnormal, equipment will send warning with the form of sound and vision, to notify medical personnel.Wherein, blood pressure is one of the most frequently used in patient care and most important vital sign.Can be comparatively fast and understand accurately the current physiological conditions of patient by monitoring of blood pressure.
Well-known be the electronic device of life-time service due to static or air-flow, easily by airborne dust, covered, serious meeting causes security risk.Especially Blood pressure monitor, owing to there being gas flow, easily takes airborne dust in gas circuit to, stop up valve or affect life-span of pump, and simply to require equipment to use in some low developed areas in clean environment be unpractical.
As shown in Figure 1, because blood pressure monitoring needs long-time use.Each blood pressure measurement all must start inflator pump at least one times, and blood pressure cuff is charged to appointment air pressure, starts inflator pump 105 at every turn and all can cause ambient air to form once in the gas circuit of blood pressure system.In general, a blood pressure measurement can be divided into inflation and two stages of venting.As Fig. 1, aeration phase, inflator pump 105 starts, and air-flow can enter inflator pump 105 by the inflation action of inflator pump 105, and then gas enters entire body 104 by inflator pump 105, finally enters cuff 101; In the venting stage, inflator pump 105 cuts out, and venting valve 103 is opened, and air-flow flows out from cuff 101, through entire body 104, from valve 103 outflows.Repeatedly measuring, in inflation and two continuous alternation procedures of stage of venting, dust can enter above-mentioned parts, life-time service with air-flow, under dust can be piled up in these parts, when dust arrives certain degree more, likely cause the reverse gas leakage of inflator pump 105, or the valve 103 that causes exitting stops up, thereby further cause blood pressure measurement inaccurate, or even cannot carry out normal blood pressure measurement, thus Blood pressure monitor cannot normally be worked, bring certain security risk.
