Carrying out clinical care when, be frequently encountered by patient unconscious situation (also just like
The when that patient paralysing).Now patient is difficult to swallow saliva by self, which results in saliva
Liquid can accumulate in the oral cavity of patient, and can overflow from mouth further or in the oral cavity
Nourish the growth of antibacterial.Meanwhile, saliva outflow also influences whether the personal image of patient
Accordingly, it would be desirable to the saliva in patient oral cavity is discharged.In correlation technique, it it is nursing
Saliva in patient oral cavity is manually discharged by personnel, but the time that this mode consumes compares
Many, especially a nursing staff nurses multiple patient simultaneously when, it is more likely that can lose
Forget some patient.
In view of this, this application provides clinical saliva drawing device of using, as Figure 1-4,
Including: by the mouthpiece 103 made by water absorbing material, negative pressure suction device 101；
Negative pressure suction device 101 includes extractor and controls the switch of extractor duty, inhales

It should be noted that the effect of mouthpiece 103 is to collect the saliva in patient's mouth, it is adopted
Make with water absorbing material, water (saliva) is had the best adsorption, is sucking
After saliva in patient oral cavity is adsorbed by part 103, just can be by negative pressure suction device 101
Attract by the moisture in mouthpiece 103, and then by the outlet of negative pressure suction device 101
The saliva that attraction gone out is discharged, or after being stored in parcel tray, concentrates and discharge.
What driving negative pressure suction device 101 (mainly extractor) worked is switch, this switch
Can be by user manual actuation, such as user Manual press, and then make switch get
Actuating signal；Can also is that and driven by timer, i.e. timer is at every predetermined time
Generate actuating signal；Can also is that by other sensor, as being arranged on the position on patient's berth
Displacement sensor controls to generate actuating signal, i.e. displacement transducer gets patient and sends action
Signal after, generate actuating signal.

Clinic saliva drawing device, and each clinic switch of saliva drawing device is set
Put in a little scope (scope that nursing staff can control), and switch all passes through to lead
The mode of line electrically connects with respective extractor respectively, and then nursing staff is in this little scope
Just can control the clinic saliva drawing device of each patient.But, this mode still needs
Nursed by nursing staff, if nursing staff goes out for a long time, then clinic can be caused to use saliva
Liquid drawing device cannot draw the saliva in patient's mouth.
And for example, using timer to trigger the situation generating actuating signal, this kind of situation is the most permissible
Accomplishing to automatically process, the timing time of timer can be adjusted as the case may be.As often
Generated one-off signal every 20 minutes, and then worked by on-off control extractor.This kind of side
Formula is suitable for the situation of long-time unmanned nursing.But this kind of mode, the timing time of timer is bad
Determine, easily cause absorption number of times excessively frequent, or draw the situation generation that number of times is very few.
As such, it can be that the timer mode manual with nursing staff combines.I.e. timer and switch

Relatively portion (such as comparator) can be arranged on other positions.Water level detected by level sensor
The amplitude of signal and water level (saliva liquid level) height correlation in oral cavity, height of water level is the highest,
The amplitude of the signal (actually detected signal) then generated is the highest.And it is actually detected by generate
Signal is transferred to an input pin of comparator, another pin of comparator and standard signal
Maker electrically connects, and this standard signal maker can generate standard signal, comparator and then compare
The amplitude size of actually detected signal and standard signal, and, when the amplitude of actually detected signal
During the amplitude of signal of being above standard, (that is, detecting when water level signal exceedes predetermined threshold) generates
Actuating signal.The mode that this kind generates actuating signal is relatively reasonable, it is possible to by monitoring trouble in real time
The intraoral liquid level of person triggers switch motion, it is ensured that only put aside in patient oral cavity
Just can draw after certain saliva, not result in and draw the situation that number of times is too much or very few.
