Description
Technical field
This utility model relates to detection of gas flow rate technology, especially one can be effectively improved accuracy of detection and not to gas
Use the air-flow sensing device producing impact.
Background technology
Oxygen uptake, as the Therapeutic Method of a kind of routine, uses widely clinically, and different patient's oxygen absorbed differences are very
Greatly.Currently, in domestic hospitals, patient's oxygen uptake is all that the mode using timing is charged, owing to not having suitable air-flow sensing dress
Put, it is impossible to realize the most automatically but also accurately different patient's various oxygen uptake processes carried out timing, nursing staff can only be relied on artificial
Record, the oxygen time causing the oxygen time of record to actually occur with patient has bigger difference, causes unreasonable charges,
Cause charge dispute and doctor-patient dispute, can not review whether patient requires strict oxygen uptake according to doctor's advice.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, to provide a kind of normal suction neither affecting patient
Oxygen, can automatically, accurately detect again patient's whether oxygen uptake and the accurate air-flow sensing device of detection oxygen flow.
The technical solution adopted in the utility model is such that including airflow line, flow sensing chip and circuit board；Institute
State flow sensing chip to be connected with described circuit board；Through hole, described flow sensing chip is offered on described airflow line sidewall
And circuit board is placed in described through hole, and flow sensing chip is towards in airflow line；The institute being connected on described circuit board
State power line and holding wire and draw described airflow line by described through hole；It is filled with close between described circuit board and described through hole
Sealing.
Preferably, described flow sensing chip exposes in airflow line from described through hole.
Preferably, described flow sensing chip is positioned at the described through hole opening part towards airflow line.
Preferably, described flow sensing chip is heat type flow quantity induction chip.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Flow sensing chip in this utility model is that the thermal field change caused by detection air-flow obtains data on flows,
As long as patient's oxygen uptake, even if tiny flow quantity also has gas flowing and thermal field can be brought to change, the therefore stream in this utility model
Amount induction chip can accurately detect different flow state and transmit signal, the range of flow width of detection.
Flow sensing chip in this utility model is positioned at airflow line sidewall, is not provided with in gas circuit, thus without shadow
Ring the normal oxygen uptake of patient；Such mounting means will not reduce gas passage area, thus reduce gas flow and cause detection
Error；Also will not form pressure loss, reduce gas pressure.Therefore flow detection precision is higher.

Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As it is shown in figure 1, one embodiment of this utility model includes airflow line 1, flow sensing chip 2 and circuit board 3；Institute
State flow sensing chip 2 to be connected with described circuit board 3.
Offering through hole 6 on described airflow line 1 sidewall, described flow sensing chip 2 and circuit board 3 are placed in described logical
In hole 6, and described flow sensing chip 2 is towards in airflow line, and in such airflow line 1 during circulated gases, gas causes gas
Thermal field change in flow tube road, described flow sensing chip 2 just can change by perception thermal field, data on flows detected.In the present embodiment
Flow sensing chip 2 select heat type flow quantity induction chip, this chip is existing product, is become by the detection thermal field that causes of air-flow
Change and obtain data on flows.The power line and the holding wire 5 that are connected to described circuit board 3 draw described gas flow tube by described through hole 6
Road 1；It is filled with fluid sealant 4 between described circuit board 3 and described through hole 6.
In a preferred embodiment, it is recommended that by described flow sensing chip 2 at described through hole 6 to airflow line 1
Inside expose, see Fig. 2.
In a further advantageous embodiment, it is recommended that described flow sensing chip 2 is positioned over described through hole 6 towards gas flow tube
Opening part in road 1, sees Fig. 3.
Both mounting means are all more beneficial for flow sensing chip and carry out thermal field perception, and to oxygen flowing shadow in pipeline
Ringing less, the mounting means of especially Fig. 3 embodiment can reduce the impact on oxygen flowing to greatest extent.
During use, this utility model device is installed between medical oxygen terminal and oxygen supply gas circuit, in other words oxygen from
Source of the gas flows out, and first flows through the airflow line in this utility model device, then then flows into medical oxygen end, and patient is by even
It is connected on the oxygen uptakes such as the oxygen inhalation apparatus in medical oxygen terminal or respirator.When patient's oxygen uptake, oxygen flows from airflow line 1
Crossing, oxygen flowing produces thermal field change, and flow sensing chip 2 transmits flow signal to circuit board 3, warp after thermal field change being detected
Circuit board 3 is exported by holding wire 5 after being converted to the signal of telecommunication of on-off model or other forms.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
