Abstract
The integrated gas path device of a kind of sphygomanometer, comprising: integrated gas circuit, filter.Described integrated gas circuit connects aerating device, means of deflation, outside cuff interface unit, filter respectively; Described filter comprises valve body 11, valve body 12 and spool 2, and valve body 11 is connected with integrated gas circuit, and valve body 12 is connected with pressure sensor component.Described integrated gas circuit adopts flexible material global formation.Described spool 2 adopts hard material to make, and spool has the hole of diameter range between 0.05mm to 0.15mm.The integrated gas path device of this utility model replaces original complex pipeline, reduces the interference that sphygomanometer is subject in gas replenishment process, thus obtains desirable pressurization value and pulse signal, and blood pressure measurement accuracy is high; Simplify number of assembling steps simultaneously, in installation process, avoid the connection of multiple flexible pipe and threeway hard tube (or four-way hard tube) pipeline, improve production efficiency.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly for measuring the sphygomanometer of human blood-pressure.
Background technology
Sphygomanometer in the market generally adopts flexible pipe to add threeway hard tube (or four-way hard tube) gas circuit, aerating device, means of deflation, pressure sensor component, outside cuff interface unit is linked together.This connected mode pipeline is complicated, there is the rough situation of tube wall at flexible pipe and hard tube contact position in pipeline, sphygomanometer exists larger interference in gas replenishment process, affects the judgement of sphygomanometer to pressurization value, cause the on the low side or higher situation of pressurizeing of sphygomanometer pressurization, finally cause measurement data inaccurate.
Summary of the invention
The purpose of this utility model is, makes up the deficiency that flexible pipe adds threeway hard tube (or four-way hard tube) gas circuit, provide a kind of can the integrated gas path device of significantly noise reduction for sphygomanometer.
The technical scheme that this utility model provides is as follows:
The integrated gas path device of a kind of sphygomanometer, comprising: integrated gas circuit, filter.Described integrated gas circuit connects aerating device, means of deflation, outside cuff interface unit, filter respectively; Described filter comprises valve body 11, valve body 12 and spool 2, and valve body 11 is connected with integrated gas circuit, and valve body 12 is connected with pressure sensor component.Described integrated gas circuit adopts flexible material global formation.Described spool 2 adopts hard material to make, and as plastics, glass or metal, spool has the hole of diameter range between 0.05mm to 0.15mm.
The integrated gas path device of this utility model replaces original complex pipeline, reduces the interference that sphygomanometer is subject in gas replenishment process, thus obtains desirable pressurization value and pulse wave signal, and blood pressure measurement accuracy is high; Simplify number of assembling steps simultaneously, in installation process, avoid the connection of multiple flexible pipe and threeway hard tube (or four-way hard tube) pipeline, improve production efficiency.
accompanying drawing illustrates:
Fig. 1 is that system realizes block diagram.
Fig. 2 is filter structure chart.
Fig. 3 for not use integrated gas path device, the jamming pattern of sphygomanometer gas replenishment process.
Fig. 4 is after using integrated gas path device, the jamming pattern of sphygomanometer gas replenishment process.
detailed description of the invention:
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1 and Figure 2, the integrated gas path device of a kind of sphygomanometer, comprises integrated gas circuit, filter, and described integrated gas circuit connects aerating device, means of deflation, outside cuff interface unit, filter respectively; Described filter comprises valve body 11, valve body 12 and spool 2, and valve body 11 is connected with integrated gas circuit, and valve body 12 is connected with pressure sensor component.Described integrated gas circuit adopts flexible material global formation.Described spool 2 adopts hard material to make, and as plastics, glass or metal, spool has the hole of diameter range between 0.05mm to 0.15mm.
Shown in Fig. 3, for not using integrated gas path device, to the jamming pattern that pulse wave signal causes in sphygomanometer gas replenishment process.Curve 1 is the pressurization value in electric sphygmomanometer gas replenishment process, and curve 2 is the composite signal of pulse wave signal and interfering signal, can find out, electric sphygmomanometer pressurization value is bigger than normal, and pulse wave signal is disturbed seriously.
Shown in Fig. 4, after using integrated gas path device, to the jamming pattern that pulse wave signal causes in sphygomanometer gas replenishment process.Curve 1 is the pressurization value in electric sphygmomanometer gas replenishment process, and curve 2 is the composite signal of pulse wave signal and interfering signal, can find out, electric sphygmomanometer pressurization value is normal, and the most of interfering signal of filtering simultaneously, obtains more satisfactory pulse wave signal.
Although this utility model with preferred embodiment openly as above; but they are not for limiting this utility model; anyly be familiar with this those skilled in the art; not departing from the spirit and scope of this utility model; can make various changes or retouch from working as, what therefore protection domain of the present utility model should define with the claims of the application is as the criterion.
