Described transfusion done state detecting unit 2 adopts capacitance level transducer or photoelectric level transducer, the installation form of its sensor can be to be contained in sensor folder upper (as shown in Figure 4), also can be mounted in tube for transfusion draw-in groove both sides, when use, sensor is clipped on tube for transfusion, or tube for transfusion is stuck in sensor draw-in groove, in the time that liquid level drops to sensor position, send a signal to Single-chip Controlling unit and carry out corresponding actions.
As shown in Figure 4, described transfusion done state detecting unit 2 adopts capacitance type liquid level to detect principle, the structure of its capacitance sensor is, two electrode slices, the 31 use Copper Foils of Detection capacitance are made, each electrode slice 31 semicirculars in shape, symmetry is fixed on the folder end inner side of sensor folder 32, when use, is clamped on the input tube for transfusion of multichannel order transfer valve 8 tops.
Described alarm unit 4 is provided with wireless transmitter module 10, and this wireless transmitter module 10 is with to call out the wireless receiving module that extension set is connected supporting with the head of a bed of hospital calling system, thereby plays the effect of controlled in wireless calling system with alarm.
The input of described Single-chip Controlling unit 1 connects manual switchover button 6, and for manual switchover transfusion path, manual switchover has precedence over automatic switchover.
The input of described Single-chip Controlling unit 1 connects multichannel order and switches transfusion device selector switch 7, for selecting multichannel order to switch the specification of transfusion device, and the commuting angle when determining that corresponding motor rotation is switched.
The input of described Single-chip Controlling unit 1 connects alert locations selector switch 9, for determining which transfusion path carries out alarm while infusing end.
Shown in Fig. 3, be the guidance panel schematic diagram of many bottles of continuous transfusion automatic sequence switch, taking four bottles as example.On and off switch and power supply indicator, battery capacity indication lamp, charging indicator light belong to power supply unit 5; Manual switchover button 6, for manual switchover transfusion path, manual switchover has precedence over automatic switchover.Multichannel order is switched transfusion device selector switch 7, for selecting multichannel order to switch the specification of transfusion device, and the commuting angle when determining that corresponding motor rotation is switched.Alert locations selector switch 9, for determining which transfusion path carries out alarm while infusing end.The installation form of the sensor of transfusion done state detecting unit 2 can be to be contained on sensor folder, as shown in Figure 4, also can be mounted in tube for transfusion draw-in groove both sides, when use, sensor is clipped on input tube for transfusion, or tube for transfusion is stuck in sensor draw-in groove, in the time that liquid level drops to sensor folder position, alarm lamp is glittering, signal is passed to the corresponding actions of Single-chip Controlling unit 1 with control step electric-motor drive unit 3 and alarm unit 4 simultaneously.Transfusion display lamp is used to indicate transfusion state, illustrates that corresponding path infuses while lighting.The motor output shaft of step motor drive unit 3 is connected with multichannel order transfer valve 8.
The operation principle of these many bottles of continuous transfusion automatic sequence switch is: in the time that the liquid level in the tube for transfusion of infusing drops to the position at transfusion done state detecting sensor place, transfusion done state detecting unit outputs signal to Single-chip Controlling unit, the setting value that Single-chip Controlling unit switches transfusion device selector switch according to multichannel order is sent corresponding pulse signal to step motor drive unit, the position that certain orientation drives the Spool rotating certain angle of " multichannel order transfer valve " to connect to next bottle of transfusion path is pressed according to this pulse signal in step motor drive unit, continue the transfusion of next bottle, Single-chip Controlling unit sends signal to alarm unit according to the setting value of alert locations selector switch and reports to the police in the time that the transfusion of corresponding transfusion path finishes.The initial position of these many bottles of continuous transfusion automatic sequence switch be the 1st bottle when transfusion corresponding position, corresponding with it, corresponding position when the initial position of the spool of " multichannel order transfer valve " is also the 1st bottle of transfusion.Transfusion, always since the 1st bottle, is then switched to the order such as the 2nd bottle, the 3rd bottle successively.
Operating procedure: with 4 bottles of continuous transfusions, adopting four bottles of continuous transfusion automatic sequence switch He Si road orders to switch transfusion device is example, and the first step, all hangs up properly 4 bottles of liquid; Second step, the bottle plug puncture unit that Jiang Si road order is switched on 4 road tube for transfusions of transfusion device inserts respectively in the bottle stopper of 4 bottles; The 3rd step, is clipped in 4 tunnel input tube for transfusions respectively on 4 transfusion done state detecting sensor folders above or is stuck in sensor draw-in groove; The 4th step, for patient's venipuncture starts transfusion; The 5th step, switches multichannel order transfusion device selector switch and alert locations selector switch and is located at respectively the position of " 4 "; The 6th step, power-on switch makes it to enter duty; The 7th step, in the time that 4 bottles of liquid are all infused end, alarm unit is reported to the police, now, and powered-down switch, for patient pulls out pin, whole infusion process finishes.
For the situation of 4 bottles of continuous transfusions, if by traditional mode, nurse must go to ward 5 times altogether, the operation 5 times of changing dressings, if with sequentially switching transfusion device in four bottles of continuous transfusion automatic sequence switch He Si roads, only need prevent or cure a disease room 2 times of nurse, operates 2 times, briefly, can save manpower 60%, nursing efficiency improves greatly, and nurse's labor intensity reduces greatly, and patient satisfaction is also bound to improve.
