Fig. 2: gas pressure sensor is realized the design of 5 kinds of different requirement with 5 diverse ways.

Fig. 3: the design that is switch: left side figure is used for closing, and the right figure is used for out.

Specify implementation procedure

Liquid level step-down slowly when having an intravenous drip, liquid level is low during to certain position, and pick off is known and is produced signal; Amplify signal, drive remote controller then, remote controller sends signal; Receptor is received signal, receptor shows signal and send prompting sound then, and pass to this patient's nurse to signal.Come if the nurse is busy, or other reason can not in time come at once, so liquid level slowly become lower, liquid level drops to and syringe needle low spot at ordinary times or a little again; Pick off perceives signal again, amplifies signal, drives remote controller then; Remote controller sends signal, and receptor is received signal, then receptor shows signal and send prompting sound; And pass to this patient's nurse to signal, clamp tube for transfusion simultaneously or no longer let liquid level descend, so just can not blood back through other way.

Each device architecture and performance:

1. sensor-based system:

Realization can be used various pick offs to the perception of liquid level, and can use various methods to realize, its main function is the position that drops to regulation when liquid level, and pick off can become the signal of telecommunication to perceptual signal, amplifies the signal of telecommunication then.Be example below with the gas pressure sensor, gas pressure sensor is when liquid level change, and liquid also and then changes the gas pressure in the gas sensor, and gas is directly proportional to cell pressure and sensor output voltage.Be to realize 5 kinds of different requirement with 5 diverse ways below with gas pressure sensor,

1. many transfusion bottles or Pig are put together, open when injection transfusion bottle or Pig that the very first time uses, and other transfusion bottle or Pig are closed; When first transfusion bottle or Pig had been beaten, sensor senses arrived, concurrent feed signals; Let first transfusion bottle or Pig close, let second transfusion bottle or Pig open, continuously work like this; Disposable a plurality of transfusion bottles or the Pig beaten beaten soon when last transfusion bottle or Pig and to be finished, and system can aut sign gives responsible this patient's nurse; And receptor sends prompting sound, closes syringe automatically.

2. work as transfusion bottle or Pig and beaten soon, only remaining 3-5 minute thing, sensor senses arrives; System can give the nurse who is responsible for this patient by aut sign; If the nurse does not come, transfusion bottle or Pig liquid level drop to and syringe needle low spot at ordinary times or a little more so, and system can notice again be responsible for this patient's nurse; Receptor sends prompting sound, and system closes tube for transfusion automatically.

3. work as transfusion bottle or Pig and beaten soon, only remaining 3-5 minute thing, sensor senses arrives, and system's meeting aut sign is given responsible this patient's nurse, and receptor sends prompting sound, and system closes tube for transfusion automatically.

4. when transfusion bottle or Pig had been beaten, injection had just left transfusion bottle or Pig, and sensor senses arrives, and system can give the nurse who is responsible for this patient by aut sign, and receptor sends prompting sound, and system closes tube for transfusion automatically.

5. work as transfusion bottle or Pig and beaten soon, only remaining 3-5 minute thing, sensor senses arrives, and system's meeting aut sign is given responsible this patient's nurse, and receptor sends prompting sound.

2. switching system:

The main effect of switch is to open or turn off tube for transfusion, can be wired or wireless, and switch can be designed to various switches, realizes it with various methods, is example outside tube for transfusion, to nip off flow liquid below:

1. close design: owing to will outside tube for transfusion, nip off flow liquid is to use very big power, so directly nipping off flow liquid with electric magnet will use very big electric current, if with basic difficult can the realization of battery powered, so done following design.Because Magnet is big more to the nearlyer suction of attraction distance of ferrum, tube for transfusion is pressed tightly more, and the pressure that needs is also big more; So can realize it; Earlier dig a u shape groove to one side of a cylinder ferrum, the horizontal iron plate in the centre of u type groove is loaded onto the lamellar tie rod at the cylindrical ferrum other end.Do a cylinder that magnetic force is not had effect again; Be placed on Magnet on one side of cylinder; On cylinder, above Magnet, make a call to a big hole, can let tube for transfusion pass through, making a call to a duck eye from Magnet and the very little cylinder position of cylinder iron phase mutual effect; Electric magnet is set up in outside at this duck eye, lets the movable axis of electric magnet aim at duck eye.Let tube for transfusion pass big hole, be placed on cylinder ferrum in the cylinder, because the movable axis of electric magnet passes duck eye under the effect of spring; Blocking cylinder ferrum is gone over by attraction; When giving electromagnetism ferroelectric, electric magnet shrinks back, and cylinder ferrum is gone over by attraction; Flatten tube for transfusion, reached the effect of turning off.

2. open design: method is the same, makes Magnet into spring, earlier spring compression, flattens tube for transfusion, lets the movable axis of electric magnet block cylinder ferrum, and electric magnet shrinks back when giving electricity, and spring rebounds, and tube for transfusion has not had the pressure conducting, the purpose that reaches out.

3. computing remote controller:

The effect of computing remote controller is to get fixed threshold values, compares the voltage and the threshold values of input, if identical output high level with threshold values makes remote controller and switch activated, realizes the purpose that you set.

4. reception transponder:

The effect that receives transponder is the coded signal remote controller, shows, and is forwarded to information on patient nurse's the mobile phone or receptor, and send prompting sound and stored record.

5. mobile phone or receptor:

The effect of mobile phone or receptor is to receive, and receives the signal that transponder sends.
