The system that this utility model is used to clamp catheter also comprises cam clamping device etc. except the electromagnetism iron clamp.A kind of cam clamping device comprises a micro machine 11 as shown in Figure 4, and the lead that this micro machine 11 connects power end is in series with the normally opened contact 12 of described relay; One cam 13, the installing hole of this cam 13 are sleeved on the axle of described micro machine 11; One fixed stop 14, this block place a side of described cam 13, have catheter 16 to pass between this block 14 and the described cam 13.This micro machine 11 and fixed stop 14 all are fixed on the same installing plate.During operate as normal, hand switch 15 is got to the right, and when the normally opened contact 12 of relay moved, circuit was connected, and micro machine 11 rotating band moving cams 13 are just changeing (counterclockwise), goes to block 14 places and stops, thereby clamp catheter 16.When medical personnel receive the calling post processing, relay is resetted, the normally opened contact 12 of relay disconnects, medical personnel get to the left side with hand switch 15 and connect circuit, and at this moment, micro machine 11 obtains opposite polarity electromotive force, micro machine 11 therefore counter-rotating drives cam 13 counter-rotatings, unclamp the catheter 16 of clamping, again hand switch 15 is got to the right, finish resetting of cam clamping system.
In addition, as improvement, side at cam, shape in conjunction with cam is provided with a position limited inching switch 17, the normally-closed contact of this position limited inching switch (switch) A and B (series connection) insert in the power supply lead-in conductor of micro machine 11, be used for when cam 13 clamps catheter, cut off the power supply of motor, avoid motor idle running damage motor, the a pair of normally opened contact A and the C of this position limited inching switch 17 are serially connected in the circuit for reversing, be used for connecting the counter-rotating power supply when position limited inching switch 17 actions, as shown in Figure 4, the main-vision surface of cam 13 is an ellipse, when the left end of ellipse turns to when just compressing catheter 16, the right-hand member of cam (ellipse) is just pushed down position limited inching switch 17 and is made its action, and normally-closed contact AB disconnects, micro machine 11 dead electricity stalls; Normally opened contact AC closure is connected the circuit for reversing power supply, and this micro machine 11 is realized counter-rotating under the cooperation of hand switch 15, thereby this transfusion controller is resetted.This microswitch 17 also is fixed on the above-mentioned installing plate.
Because having adopted safe transfusion tube, the automatically controlled folder in the present embodiment is as the safe further guarantee of transfusion in fact.
Embodiment 2:
Introduced microprocessor on the basis of embodiment 1, the annexation block diagram of each module as shown in Figure 5.The core of present embodiment is a microprocessor, proximity transducer (photoelectric sensor, ultrasonic sensor or voltage sensitive sensor etc.) output signal is to microprocessor, the microprocessor output alarm signal is to alarm, the output call signal is to calling set, the output control signal is controlled the action of automatically controlled folder, microprocessor also is connected with the reservation port, is used for the function expansion of this transfusion controller.
Described automatically controlled folder is electromagnetism iron clamp or cam clamping device (as shown in Figure 4) etc.
In addition, the drive circuit between microprocessor or proximity transducer (or other pick offs) and the automatically controlled folder can adopt multiple mode.As follows:
As shown in Figure 6, this drive circuit adopts audion T as switching device, be in series with a resistance R and relay coil J between the colelctor electrode of audion T and the power supply vcc, input signal in is the output signal (level signal or pulse signal) of an output port of microprocessor, or the outputs level signals of proximity transducer, or the output signal of proximity transducer is through a pulse signal of pulse delay unit output, the state of the normally opened contact K of relay is as output, the normally opened contact K of relay can insert in as shown in Figure 4 the circuit (being relay normally open contact 12), is used to start micro machine.The normally opened contact K of relay can be connected in the circuit of electromagnetism iron clamp, is used to control the action of electromagnetism iron clamp.When signal in is high level (perhaps pulse signal positive pulse), audion T conducting, relay coil J invocation point, the actuating of relay, normally opened contact K closes, micro machine or the action of electromagnetism iron clamp; Otherwise as signal in is low level (voltage is zero or is negative), and then audion T ends, not conducting of circuit, and the relay coil dead electricity resets, and normally opened contact is opened, and can be used for controlling the action of electromagnetism iron clamp or cam clamping system thus.
Circuit as shown in Figure 7 is a simple signal amplification circuit, input signal in is the output signal (level signal or pulse signal) of an output port of microprocessor, or the outputs level signals of proximity transducer (in case of necessity through a non-output more behind the door), or the output signal of proximity transducer is through a pulse signal of pulse delay unit output, signal in connects the base stage of audion T, the colelctor electrode of audion T meets positive supply vcc by a resistance R, collector terminal is outfan out, outfan out can connect the micro machine or the electromagnetism iron clamp of cam clamping system, and as the positive power source terminal of this micro machine or electromagnetism iron clamp.Its operation principle is as follows, when signal in is a high level, and audion T conducting, output signal out is a low level, micro machine does not start, or the electromagnetism iron clamp is failure to actuate; Otherwise when signal in is a low level, audion T ends, and outfan out exports high level, and then micro machine starts, or the action of electromagnetism iron clamp.As seen, this circuit is that low level is effective, therefore, where necessary, at input in place or outfan out place add a not gate, make logic control relation more smooth and easy, then can use this circuit more expediently.
For described cam clamping system, its control signal (as signal in) preferably adopts impulse form because adopt pulse can realize micro machine in a setting-up time electric rotation, and if adopt the level form, then micro machine after startup always electric, influence service life of micro machine.For microprocessor, be easy to realize from pulse signal of an I/O port output; For the system that does not adopt microprocessor, then between signal of sensor and signal in, add a pulse generator and get final product.
