Specific embodiment
Below in conjunction with attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
When carrying out clinical care, the case where frequently encountering patient unconscious (also just like patient's paralysis when
It waits).Patient is difficult to swallow saliva by itself at this time, and which results in salivas to accumulate in the oral cavity of patient, and into one
Step can overflow the growth for either nourishing bacterium in the oral cavity from mouth.Meanwhile saliva outflow also influences whether the individual of patient
Image
Therefore, it is necessary to the saliva in patient oral cavity is discharged.It in the related technology, is nursing staff manually by patient mouthful
Saliva in chamber is discharged, but the time that this mode consumes is relatively more, is especially nursed simultaneously in a nursing staff more
When a patient, it is more likely that certain patients can be forgotten.
In view of this, this application provides clinic saliva drawing devices, as shown in Figs 1-4, comprising: by water-absorbing material
Made mouthpiece 103, negative pressure suction device 101；
Negative pressure suction device 101 includes the switch of extractor and control extractor working condition, extractor and mouthpiece 103
Connection；
Switch is electrically connected with extractor, for when getting action signal, control extractor to work.
It should be noted that the effect of mouthpiece 103 is the saliva collected in patient mouthful, water-absorbing material system is used
At, have better suction-operated to water (saliva), mouthpiece 103 by patient oral cavity saliva absorption after, just
The moisture in mouthpiece 103 can be attracted out by negative pressure suction device 101, and then pass through the discharge of negative pressure suction device 101
Mouthful saliva out will be attracted to be discharged, or after being previously stored in storage box, concentrate discharge.
Driving negative pressure suction device 101 (mainly extractor) work is switch, which can be by user's hand
Dynamic driving, such as user's Manual press, and then switch is made to get action signal；It can also be through timer driving,
That is, timer generates action signal at every predetermined time；It can also be by other sensors, be such as arranged on patient's bed
Displacement sensor control generation action signal, that is, after displacement sensor gets the signal of patient sending movement, generate dynamic
Make signal.
The generating mode of above-mentioned three kinds of action signals is suitable for different scenes, as push switch is preferably made by nursing staff
With nursing staff can generate action signal by push switch at a distance.Specifically, can be as in the same ward
Each patient configures clinic provided herein saliva drawing device, and will be each clinical with saliva drawing device
Switch is all disposed within an a small range (range that nursing staff can control), and is switched and all distinguished by way of conducting wire
It is electrically connected with respective extractor, and then nursing staff uses saliva in the clinic that this small range can control each patient
Drawing device.But this mode still needs to be nursed by nursing staff, if nursing staff is outgoing for a long time, can lead
Cause the clinical saliva that can not be drawn in patient mouthful with saliva drawing device.
For another example, the case where generating action signal is triggered using timer, such situation can accomplish to automatically process substantially, meter
When device timing time can be adjusted as the case may be.Such as every 20 minutes generation one-off signals, and then by opening
Close control extractor work.Such mode is suitble to the case where unmanned nursing for a long time.But such mode, the timing time of timer
Bad determination be easy to cause absorption number excessively frequent, or draws the very few situation of number and occur.As such, it can be that meter
When device with nursing staff, manually mode is combined.I.e. timer is electrically connected with switch, is acted for generation at predetermined time intervals
Signal, and, switch the control extractor work after getting user or action signal that timer is issued.
Preferably, clinic provided herein saliva drawing device further includes the water that 103 surface of mouthpiece is arranged in
Level sensor, water level sensor are electrically connected with switch, for when detecting that water level signal is more than predetermined threshold, generation movement to be believed
Number.
There is certain limitation by timer either nursing staff's manual operation.It determines when that absorption should be controlled
Can be by water level sensor for device work controls.Specifically, being at least level sensor set by 103 surface of mouthpiece
The comparing section (such as comparator) of the probe portion of device, water level sensor can be set in other positions.Detected by water level sensor
Water level signal amplitude and oral cavity in water level (saliva liquid level) it is highly relevant, height of water level is higher, then the signal that generates is (real
Border detect signal) amplitude it is higher.And the actually detected signal of generation is transferred to an input pin of comparator, is compared
Another pin of device is electrically connected with standard signal generator, which can generate standard signal, comparator into
And the amplitude size of more actually detected signal and standard signal, also, when the amplitude of actually detected signal is above standard signal
Amplitude when (that is, detect water level signal be more than predetermined threshold when) generate action signal.Such mode for generating action signal
It is relatively reasonable, it can ensure that only patient mouthful by the intraoral liquid level of real-time monitoring patient come trigger switch movement
It just will do it absorption after having put aside certain saliva in chamber, not will cause and draw the excessive or very few situation of number.
