Specific embodiment
Detailed content and its specific embodiment of the invention are further illustrated with reference to the accompanying drawing.
Shown in Figure 1, infusion/urine collection bag flow velocity of the invention precisely detects warning device, including gravity sensor 1,
Acceleration transducer 7, control and detection module 2, signal projector 3, signal receiver 6, computer 5, battery 4, the gravity pass
Sensor 1, acceleration transducer 7, signal projector 3 are connect with the control with detection module 2 respectively, the signal projector 3
It is connected by signal receiver 6 with computer 5, battery 4 is connected with gravity sensor 1 and acceleration transducer 7；The control and inspection
Survey module 2, gravity sensor 1, acceleration transducer 7, the infusion of the composition of signal projector 3, urine collection bag testing agency, the signal
Receiver 6 and the infusion of the composition of computer 5, urine collection bag alarm mechanism；The infusion, urine collection bag testing agency and infusion bottle, urine collection bag
It is connected and is mounted in ward, the infusion, urine collection bag alarm mechanism is mounted on nurse's duty room.
The signal projector 3 is wireless signal transmitter, and the signal receiver 6 is wireless signal receiver.
The control and detection module 2 is 51 single-chip microcontrollers.
There are three LED light in the control and detection module 2, green light indicates normal together, and amber light indicates that flow velocity is too fast
Or it is excessively slow, red light, which lights, indicates that infusion is near completion or urine collection bag will be filled.
The gravity sensor 1 is tension sensor, is directly connected with infusion bottle, urine collection bag.

Infusion of the invention/accurate the detection method of urine collection bag flow velocity, including be infused whether complete detection, urine collection bag whether
The detection filled and infusion flow rate is accurately measured, the detection method whether completed of being infused is:
The gravity sensing formula of gravity sensor 1 are as follows: G=mg
Wherein, G is gravity, and m is quality, and g is gravity coefficient；On the earth, g is approximately equal to 9.8 every kilogram of newton；
By controlling the initial weight value common with the infusion bag of the input different size of detection module 2 and transfusion liquid, urine collection bag
Initial weight value, the variation of 1 real-time detection weight difference of gravity sensor；G=| Gi-Gn |, wherein Gi is initial weight value,
Gn is real-time weight value；G is the absolute value of the difference of Gi and Gn；
The initial weight value that the infusion bag and transfusion liquid of input control and detection module 2 are common is greater than actual weight Mg.
In general, when infusion is near completion, can also remnant has not been beaten in perfusion tube liquid therefore controlling
It is greater than actual weight when making the weight common with the input different size infusion bag of detection module 2 and transfusion liquid, typically larger than
Actual weight Mg.In this way, when judging whether that infusion is completed, when the difference between initial weight value Gi and real-time weight value Gn
Absolute value be equal to initial weight value Gi when, be judged to being infused completions, and actually also infusion segment liquid in perfusion tube after
Continuous infusion not will cause infusion and complete the hidden danger generated.
The detection method whether urine collection bag is filled is:
The initial weight value of the urine collection bag of input control and detection module 2 is less than actual weight Lg.In this way, judging that urine collection bag is
It is not no when filling, when the absolute value of the difference between the initial weight value and real-time weight value of urine collection bag is equal to urine collection bag initial weight
When value, it is judged as that urine collection bag is filled, and actually urine collection bag is not completely filled up also, prevents urine collection bag urine from overflowing.
The method for accurately measuring infusion flow rate is:
T is interval timer, by V=g/T calculates the variation speed of the real-time weight value of infusion bag and transfusion liquid jointly
Degree, it can accurately measure infusion flow rate；When V > 5ml/min is to be judged as flow velocity when infusion flow rate is greater than 5 milliliters per minute
It is too fast, when V < 2ml/min is to be judged as that flow velocity is excessively slow when infusion flow rate is less than 2 milliliters per minute；And transmit a signal to letter
Number transmitter.
From kinematic angle, the original definition formula of acceleration are as follows: a=V/T, that is, velocity function is to the time
Speed.That is: when the time infinitely in short-term, the increment of speed is exactly acceleration a, and unit is m/s2.Acceleration is used to judge detection dress
Set whether violent displacement occurs for the short time, when acceleration transducer judges that detection device is horizontally or vertically waiting directions
Violent acceleration, at this point, infusion bag may acutely shake.All directions acceleration is decomposed into horizontal and vertical add by the present invention
Speed, the in this way present invention only need the acceleration of determined level and vertical direction it may determine that whether infusion bag occurs acutely to tremble
It is dynamic.Acceleration usually has the acceleration of all directions, this direction is decomposed into horizontal and vertical two with acceleration transducer
The acceleration in direction.Horizontal acceleration and normal acceleration are set as Km/s with detection module in control2, K be it is described control with
The initial value of detection module input.
Value Km/s is set with the first of detection module when acceleration a is greater than given control2When, be judged as that acceleration is too fast, i.e., it is defeated
Liquid bag, urine collection bag, which generate, acutely to be shaken.At this point, interrupting the signal of the calculating infusion flow rate of real-time transmission.Control and detection mould
Signal is transmitted to signal projector by block.
The foregoing is merely preferred embodiments of the invention, are not intended to restrict the invention, for the technology of this field
For personnel, the invention may be variously modified and varied.All any modification, equivalent substitution, improvement and etc. made for the present invention,
It should all be included in the protection scope of the present invention.
