Abstract
The utility model discloses a kind of flow sensor mounting devices for ventilator, including ratio valve housing adapter, sebific duct, sealing ring, mixed gas module adapter, the inlet end of ratio valve housing adapter and the outlet side of ratio valve housing are fixed and are connected, it docks and is connected with the gas input of flow sensor in the outlet side of ratio valve housing adapter, outer surface at the docking of ratio valve housing adapter and flow sensor, which is arranged, is sealed with sebific duct, the inlet end of mixed gas module adapter is arranged with sealing ring, the inlet end of mixed gas module adapter is plugged in the inner conical surface of the gas output end of flow sensor and is sealed by sealing ring.The soft sealed connection in the both ends of flow sensor reduces it always not by the extruding of external force, to mating requirement at work, ensure the long-term normal work of flow sensor, enable the adjusting fast reaction of front end flow proportion valve, lag time shortens, and improves the reliability of ventilator.
Description
Technical field
The utility model relates to ventilator technical fields, install more particularly to a kind of flow sensor for ventilator
Device.
Background technique
Flow sensor on ventilator is a kind of sensor for measuring gas flow, and the reaction time is fast, performance
Well, therefore it is very convenient.Modern ventilator, can be very square using the size of integrated circuit control proportioning valve on-load voltage or electric current
Just realization controls the ventilator air oxygen air-flow set by flow proportion valve output to the timing of air-flow, constant volume, level pressure
Amount proportion and uninterrupted.Empty oxygen mixer is the important component of ventilator, the oxygen concentration of output gas to patient is adjustable model
It is trapped among 21%~100%, to reach scheduled concentration, then is obtained by adjusting air and the oxygen flow of front end input, because
This, the flow sensor of front end need to timely feedback the flow number measured so as to the oxygen of host adjustment flow proportion valve input and
Air mass flow reaches the empty oxygen ratios of needs.
Flow sensor main body used in ventilator is plastic part, and both ends are the conical surface, and traditional connection type is hard close
Envelope, there is extruding between face and face, require height to matched component processing, and breakage is also easy after long-term work aging and is split,
Cause the inaccuracy of measurement.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of novel flow for ventilator
Installation device of sensor effectively avoids the breakage of flow sensor, can ensure the long-term normal work of flow sensor in ventilator
Make.
The utility model is to solve above-mentioned technical problem by following technical proposals:
The utility model provides a kind of flow sensor mounting device for ventilator, it is characterized in that comprising ratio
Example valve housing adapter, sebific duct, sealing ring, mixed gas module adapter, the inlet end of the ratio valve housing adapter
It fixes and is connected with the outlet side of ratio valve housing, the outlet side of the ratio valve housing adapter and the flow sensor
Gas input docking and be connected, the appearance surface cover at the docking of the ratio valve housing adapter and the flow sensor
If being sealed with the sebific duct, the inlet end of the mixed gas module adapter is arranged with the sealing ring, mixed gas module switching
The inlet end of head is plugged in the inner conical surface of the gas output end of the flow sensor and is sealed by the sealing ring.
Preferably, the sebific duct is silicone rubber tube.
Preferably, the internal diameter of the sebific duct is less than the inner conical surface smallest end of the gas input of the flow sensor.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get the utility model respectively compared with
Good example.
The positive effect of the utility model is:
The inlet end of the flow sensor of the utility model and outlet side can allow its inlet end by soft sealed connection
With outlet side at work always not by the extruding of external force, the mating requirement to match therewith is accordingly reduced, has ensured flow
The long-term normal work of sensor enables the adjusting fast reaction of front end flow proportion valve, and lag time shortens, improves and exhale
The reliability of suction machine.
Detailed description of the invention
Fig. 1 is the exploded view of the flow sensor mounting device of the utility model preferred embodiment.
Fig. 2 is the assembling figure of the flow sensor mounting device of the utility model preferred embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of flow sensor mounting devices for ventilator comprising ratio
Example valve housing adapter 2, silicone rubber tube 3, sealing ring 5, the mixed gas module adapter being installed on sky oxygen mixing module 7
6, the inlet end of the ratio valve housing adapter 2 and the outlet side of ratio valve housing 1 are fixed and are connected, proportioning valve peace
The outlet side for filling seat adapter 2 docks and is connected with the gas input of the flow sensor 4, ratio valve housing switching
First 2 and the flow sensor 4 docking at outer surface be arranged and be sealed with the silicone rubber tube 3, the mixed gas module adapter 6
Inlet end be arranged with the sealing ring 5, the inlet end of the mixed gas module adapter 6 plugs the gas of the flow sensor 4
It is sealed in the inner conical surface of output end and by the sealing ring 5.
Moreover, the internal diameter of the silicone rubber tube 3 is less than the inner conical surface smallest end of the gas input of the flow sensor 4.It can
It is close directly ratio valve housing adapter 2 and 4 inlet end of flow sensor are closely joined together by silicone rubber tube 3
It secures and leans on.
The flow sensor installation of the utility model improves design simply, can be ignored in cost, flow is given to pass
The use environment of one safety and stability of sensor avoids external force from squeezing adverse effect caused by flow sensor, has ensured flow
The normal work of sensor improves the reliability of ventilator.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the protection scope of the utility model.
