Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of with the real-time self-checking function of bubble circuit
Infusion pump systems.
Background technique
It is well known that in infusion process, if there is a certain number of bubbles mix in blood, it is possible to cause heart
Embolism generates damage to patient safety, it could even be possible to jeopardizing the life of patient.Current infusion pump generallys use bubble sensing
Device has bubble-free to detect in perfusion tube.It, can be to patient the problem of there are also in terms of some reliabilities but during practice
Generate certain potential risk.For example,
1) during producing air bubble sensor, it is possible to the rosin joint that the short time can not be detected occur, it is possible to have
A certain proportion of bad air bubble sensor flows in user hand, generates risk to the safety of patient；
2) bubble detection circuit may also be interfered and generate wrong report or not report bubble (due to technology, at present
Mobile phone of the infusion pump to short distance, nuclear-magnetism, the resistance that electric knife etc. generates high-frequency electromagnetic interference is strong)；
3) device of signal processing circuit itself may also damage, it is also possible to cause to report or do not report bubble by mistake；
4) there are also an installation site problems for single isolated bubbles sensor.If air bubble sensor is mounted in pump housing upstream, bubble
Sensor can also be achieved obstruction and air emptying function in detection other than bubble detection function.But within the scope of certain temperature, with
Multiple pump pieces in the pump housing of infusion pump constantly squeeze medical fluid, and some small bubbles will be precipitated in medical fluid, and the bubble of upstream passes
Sensor can not detect the minute bubbles of these precipitations；If after air bubble sensor is put into pump housing downstream, can detecte above-mentioned stingy
Bubble, but be originally placed on upper obstruction that pump housing upstream has concurrently and emptying detection function and can only just design by blocking in special detection and arranging
Empty sensor is realized, will increase a little costs.
Producer reinforces production process control and exfactory inspection, can improve the reliability of bubble detection to a certain extent.Portion
Man, subsidiary factory provides startup self-detection function, can improve the reliability of bubble detection again.But this does not prevent running device
Damage, also not preventing interference, (infusion pump requires at present and electric knife, nuclear-magnetism, the equipment such as mobile phone keep certain distance could just
It is often used), so there are also certain wrong report situations for current bubble detection, threaten to patient safety.
In summary, there is inconvenient and reliability in the infusion pump systems, it is therefore necessary to be changed in practice
Into.

10.The first bubble sensor 3, the second air bubble sensor 4 are ultrasonic bubble sensor.
Utility model works principle:
Because first bubble sensor 3, first switch 8, the first signal processing module 5 it is corresponding with the second air bubble sensor 4, the
Two switches 9, the working principle of second signal processing module 6 are similar, here with first bubble sensor 3, first switch 8, first
Signal processing module 5 is illustrated.
The first bubble that is switched on or switched off to control that controller 12 can control first switch 8 detects signal generator 51
Detection signal whether be issued to the first transmitter 31 of first bubble sensor 3.When being not provided with first switch 8, control
Device 12 still can be controlled by being arranged first bubble detection signal generator 51 will test signal be sent to first bubble sensing
The first transmitter 31 of device 3, only first bubble detection signal generator 51 restarting need the time, and bubble detection may
Postponed.And it is provided with first switch 8, first bubble, which is only turned off, when disconnecting first bubble detection signal generator 51 passes
The input of sensor 3 does not stop the work of first bubble detection signal generator 51, can save first bubble detection signal hair
The starting time that raw device 51 is reworked ensures the bubble detection of higher flow rate.
The bubble of normal detection perfusion tube 11: controller 12 can instruct first bubble detection signal generator 51 to send detection
Signal is to the first transmitter 31 of first bubble sensor 3, and then first bubble sensor 3, first bubble detection circuit 52 be just
Bubble regime can be detected, and will test result and feed back to controller 12；If there is bubble, controller 12 can pass through
Indicator light 10 and voice guard 7 issue alarm signal, otherwise work on.
When self-test (whether system detection air bubble sensor works normally): the first signal processing module can be in work operation
On-line self-diagnosis is carried out by the control of controller, to guarantee the first signal processing module in any condition, keeps bubble detection
Otherwise ability can issue alarm signal, remind operator's processing.The instruction of controller 12 disconnects first switch 8, first bubble
It detects signal generator 51 and stops sending detection signal to the first transmitter 31 of first bubble sensor 3, then first bubble
Detection circuit 52 will test signal and feed back to controller 12；If it is bubble regime, then entire link is normal, can detect
Bubble；Otherwise illustrate there is exception in entire link, cannot detect bubble, then controller 12 passes through indicator light 10 and sound
Alarm 7 issues alarm signal.Because the time that self-test is spent is very short (less than 1 millisecond), it is possible to be inserted at work
Self-test, realizes real-time self-test not and influences system and work on.After the completion of self-test, controller 12 can instruct control first switch 8 and connect
Logical, if 11 position of perfusion tube of first bubble sensor 3 does not occur bubble, first bubble detects the signal of signal generator 51
The first receiver 32 can be reached through the first transmitter 31 of first bubble sensor 3, can continue to work normally；If the first gas
When bubble occurs in 11 position of perfusion tube of bubble sensor 3, the first receiver 32 of first bubble sensor 3 does not receive the first hair
The signal of emitter 31, then controller 12 is alarmed by indicator light 10 and voice guard 7.The frequency of self-test can as needed into
Row setting.
In addition, the first bubble sensor 3 of the infusion pump systems, the second air bubble sensor 4 are separately positioned on the upper of the pump housing 1
11 surface of perfusion tube of trip and downstream, the first bubble sensor 3 of upstream can carry out detecting obstruction and perfusion tube 11 simultaneously
Whether (medical fluid be finished, bottle empty) is emptied.When upper obstruction (perfusion tube 11 in 1 upstream of the pump housing blocks) occurs, due to pump
Body 1 constantly takes the medical fluid of 1 upstream of the pump housing away, and when upper obstruction does not have medical fluid to add in the upstream infusion tube 11 of the pump housing 1, perfusion tube
11 are inhaled flat and generate gap with first bubble sensor 3, and the signal for being transmitted to first bubble sensor 3 at this time is cut off, the
One bubble detection circuit 52 will bubble up state, and controller 12 issues alarm after perceiving this problem in time.Emptying detects
Infusion pump systems detect whether that infusion is completed automatically, and after the completion of infusion, first bubble sensor can detect very long bubble.Pump
The upstream setting first bubble sensor 3 of body 1 can detect medical fluid emptying state in time.The second sensor 4 in downstream can be examined
It measures multiple pump pieces in the pump housing and constantly squeezes medical fluid and some small bubbles are precipitated.
1 upstream and downstream of the pump housing is respectively arranged an air bubble sensor and additionally aids after exception occurs in a bubble sensor wherein, another
Air bubble sensor can also work on, to guarantee the rescue or treatment of patient, can continue to carry out.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
