Description
This utility model relates to a kind of human internal organ monitoring device, specifically, is a kind of device that detects breathing function.
The patient that the DE of asthma, bronchitis and lung tissue lowers, can declare with the expiration situation and distinguish its state of an illness, for example, someone shields to live after suctioning gas slightly, reuse power is breathed out gas, survey the situation that its expiration peak speed value (PEF) just can reflect its pulmonary function, health status is good more, and the peak speed value of then exhaling is big more; Expiration peak speed value is also relevant with sex with the year order, the postadolescent maximum, and childhood and old age are all less, male's ratio women's is big, expiration peak speed value PET (liter/minute) is lower than normal value must go to a doctor immediately below 20%, it serves to show the clinical meaning of PET value, but it ties up to the expiration peak that uses at present speed pH-value determination pH device the tube port of export of exhaling the detection thin slice is set, with its passing of being exhaled distance represent to exhale size of peak speed value, though it is structurally very simple, but precision is relatively poor, and easily causes the subjective error of reading.
The purpose of this utility model provides a kind of certainty of measurement height, digital pocket expiration peak speed pH-value determination pH device.
This utility model is to realize like this, it comprises the expiration tube and becomes the casing that can load and unload connection with it, be characterized in: be positioned at plant place of this expiration tube in this casing and establish wind wheel and wind wheel test the speed infrared detector and the shaping amplifying unit, frequency one voltage conversion unit, peak value holding unit, A/D converting unit and the LCDs that connect this infrared detector after having and connect with circuit successively; And the delayed latch signal element that connects this shaping amplifying unit and A/D converting unit.
Casing in above-mentioned this utility model can be single body structure or casing comprises fixed part and become the side of rotatable connection to close portion with the one side, and the case face of this fixed part is established LCDs, and this side is closed portion and become the connection of removably planting with this expiration tube; And the fixed part in the casing and side are closed rotatable bracing between portion and are included in this side and close the joint face of portion and establish rotating shaft, offer with suitable the inserting the hole and insert the rear, hole at this of rotating shaft at the joint face of this fixed part and establish the locking plate that connects mutually with this rotating shaft; The conjugation tube that tube and bore outside the plant bracing of casing is provided with in this casing match with bore in this expiration port of export of exhaling, and in this conjugation tube, establish wind wheel and at its tube wall this infrared detector is installed.
The utility model has the advantages that: 1, certainty of measurement height, convenient reading shows the subjective error of eliminating reading with numeral; 2, carry, easy to use; 3, layer of structure is clearly demarcated, is easy to produce and maintenance.
