Description
Technical field
This utility model relates to a kind of pulse blood oxygen instrument, especially a kind of fingernail formula pulse blood oxygen instrument that can switch the direction of screen display interface.
Background technology
Pulse blood oxygen instrument is to measure in the blood percentage ratio that is accounted for whole combinative hemoglobin (Hb) capacity by the capacity of the bonded oxygenated blood red eggs of oxygen (HbO2), and promptly the concentration of blood oxygen in the blood is the important physiological parameter of respiratory circulatory system.The disease of many respiratory systems can cause the minimizing of blood oxygen saturation in the blood of human body; Damage that the automatic regulatory function of body that is caused by anesthesia in addition is not normal, major operation wound and some medical examination cause etc.; All possibly cause patient's oxygen supply generation problem and reduce the blood oxygen saturation of human body; Symptoms such as the render patients appearance is dizzy, unable, vomiting, weight person is entail dangers to life then.Therefore the blood oxygen saturation situation of in time understanding patient helps to cure cattle in time pinpoints the problems, and in the clinical treatment field crucial meaning is arranged.In addition, existing fingernail formula pulse blood oxygen instrument volume is little, low in energy consumption, easy to use, is easy to carry, and inserts in the finger cot type photoelectric sensor as long as will point during measurement, and display screen will directly show the oximetry value of surveying.Clinical experiment shows to have higher accuracy and repeatability.Therefore fingernail formula pulse blood oxygen instrument has environmental protection, pacifies characteristics such as individual, convenient, accurate.
Test the blood oxygen saturation of self for ease whenever and wherever possible, so much human is accustomed to all fingernail formula pulse blood oxygen instrument is carried, is provided with to be worn over always and makes things convenient for immediate observation on the finger.All need pulse blood oxygen instrument to possess the function of automatic switchover display screen, so that user is observed from different perspectives or changed hands and wear observation.In the prior art; The existing technology that can solve the display interface automatic switchover; The technology that adopts ball switch to judge switching is also arranged in these technology; Wherein ball switch also is the steel ball switch, and the pearl switch is connecting or disconnecting of control circuit or signal through the principle of pearl rolling contact guide pin.In simple terms, just as turning on or to turn off electric light the same, the metallic plate electric light of switch touching the inside is just bright, just leaves and closes, and ball switch also is to utilize similar principle.Utilize the rolling of the globule in the switch, make the route of advancing, just can produce the effect of conducting or not conducting with the touching or the change light of metal terminal.But these switching modes judge whether need switch display interface with the employing acceleration sensor, all have a deficiency, are exactly when gradient is between 0 °-15 °, just can not sense.When the gradient of pulse blood oxygen instrument was spent less than 15, frequent switch or not switching will appear in display interface, thereby user just must rotate blood oxygen appearance significantly and can make the direction of display interface accurately show, thus make operate inconvenient.
The utility model content
The purpose of this utility model is exactly in order to overcome the deficiency that above-mentioned display interface direction is switched, to provide a kind of display interface direction to switch accurately pulse blood oxygen instrument simple in structure.
The technical scheme that this utility model is adopted to achieve these goals is:
A kind of fingernail formula pulse blood oxygen instrument with display interface automatic switchover; It is characterized in that comprising microprocessor, be used to survey detector, power supply, display screen and the control display interface direction change-over switch of pulse and blood oxygen saturation; Said power supply connects detector, microprocessor and display screen respectively; Microprocessor connects detector and display screen, and said control display interface direction change-over switch connects power supply and microprocessor.
According to the fingernail formula pulse blood oxygen instrument that display interface automaticallyes switch that has that is provided in this utility model, it is characterized in that said microprocessor has comprised blood oxygen module, meter step module and driver module.
The fingernail formula pulse blood oxygen instrument that display interface automaticallyes switch that has according to being provided in this utility model is characterized in that said microprocessor also comprises the automatic switching module.
This utility model also specialized designs a kind of control display screen direction change-over switch, this switch is made up of two ball switch that are obliquely installed, said each ball switch and horizontal sextant angle be 15 spend to 60 the degree.
According to the control display screen direction change-over switch that is provided in this utility model, it is characterized in that said each ball switch and horizontal sextant angle are preferably 15 degree.
This utility model is through increasing the switch of the accurate switching displayed of an ability interface direction on existing pulse blood oxygen instrument; Thereby user can change hands arbitrarily and wear; Swing is pointed arbitrarily; When having overcome existing pulse blood oxygen instrument rotation amplitude and spending less than 15, the deficiency that display interface frequently switches or do not switch is used convenient.Secondly this utility model is used through adopting two ball switch, and employing acceleration transducer price is cheaper, performance is more stable compared with having now.
Description of drawings
Fig. 1 is this utility model structured flowchart.
Fig. 2 control display screen direction Switch structure sketch map.
Fig. 3 is the ball switch structural representation.
Among the figure: 1-ball switch, 2-Metal Ball, 3-first pin, 4-second pin.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing, but this utility model is not limited in following embodiment this utility model.
As shown in Figure 1: a kind of fingernail formula pulse blood oxygen instrument with display interface automatic switchover; Comprise microprocessor, be used to survey detector, power supply, display screen and the control display interface direction change-over switch of pulse and blood oxygen saturation; Said power supply connects detector, microprocessor and display screen respectively; Microprocessor connects detector and display screen, and said control display interface direction change-over switch connects power supply and microprocessor.Said microprocessor has comprised blood oxygen module, meter step module and driver module, and said microprocessor also comprises the automatic switching module.
Like Fig. 2, shown in 3: Fig. 2 is a control display screen direction Switch structure sketch map, and Fig. 3 is single ball switch structural representation.This control display screen direction change-over switch is to be obliquely installed ball switch by two to constitute.Ball switch 1 is 15 with horizontal sextant angle; And but two free rolling Metal Ball 2 are housed all in two ball switch 1; First pin 3 at the two ends of two ball switch 1 and second pin 4; Wherein first pin 3 is connected on the housing of ball switch 1, and second pin 4 passes ball switch 1 housing and is communicated with ball switch is interior.During actual production, the angle between ball switch 1 and the level can be spent between 60 degree 15 according to actual needs and regulated arbitrarily, and the quantity of Metal Ball 2 also can increase and decrease in right amount.
The operation principle of this switch is to utilize Metal Ball 2 in the ball switch 1 according to the incline direction of whole instrument; Then to rolling on one side, when being rolled into second pin, Continuity signal then; This sampling instrument just can be judged and whether carried out tangent screen according to signal conduction situation and setting in advance.The control display screen direction change-over switch of this utility model adopts two ball switch to constitute, and has overcome existingly to utilize a ball switch to control separately and can not solve the whole instrument angle of inclination in 15 ° the time, the deficiency that screen does not switch or frequently switches.
