Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, to enable those skilled in the art referring to specification Text can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein are not precluded one or more The presence or addition of a other elements or combinations thereof.
As shown in Figure 1-3, a kind of infusion support with quantitative constant speed warning function of the present embodiment, including infusion support sheet Body, the tension sensor being set on the hook 3 of infusion support ontology, 2 harmony of the micro-control unit being set on infusion support ontology Light alarm module and the remote controler connected with the wireless communication of micro-control unit 2,
Tension sensor real-time monitoring is suspended on the weight of the infusion bottle on hook 3, and real-time Transmission is to micro-control unit 2；
Remote controler is used to set the medical fluid margin value and transfusion speed range of infusion bottle in infusion process；
Micro-control unit 2 monitors the medical fluid surplus and transfusion speed of infusion bottle in real time, when the medicine in infusion bottle When liquid surplus is more than the transfusion speed range of setting lower than the medical fluid margin value or transfusion speed of setting, micro-control unit 2 is controlled Sound and light alarm module processed issues sound and light alarm signal.
In one embodiment, infusion support ontology includes pedestal 9, the universal wheel 10 for being set to 9 bottom of pedestal, is set to bottom Upper loop bar 4 and lower 6 junction of loop bar is arranged in lower loop bar 6, the scalable upper loop bar 4 being plugged in lower loop bar 6 on seat 9 Elastic sleeve 5, the tray 8 being arranged on lower loop bar 6 and the pullover 1 that upper 4 top of loop bar is set.Upper loop bar 4 and lower loop bar 6 Between scalable connection, locking can be realized by elastic sleeve 5.Wherein, micro-control unit 2 is set to inside pullover 1, hook 3 It is set to 4 top of loop bar.Such as Fig. 2, sound and light alarm module includes the indicator light 7 and voice guard being arranged on lower loop bar 6 PWM controller is respectively connected between indicator light 7, voice guard and micro-control unit 2.Brake is provided on universal wheel 10.? In further preferred embodiment, remote controler is IR remote controller.The information that remote controler inputs is transferred to by common IO micro- Control unit 2.The measured value of tension sensor is passed in micro-control unit 2 (MCU) by IIC interface.
Reference figure, 4, monitoring method of the micro-control unit 2 to the medical fluid surplus of infusion bottle specifically: pass through pulling force first and pass Sensor measures the gross mass of infusion bottle and medical fluid therein, is denoted as m, and be transmitted to micro-control unit 2；After infusion starts, pulling force Sensor is by its measured value x real-time Transmission to micro-control unit 2, and medical staff is according to the different need of the different patients of all ages and classes It asks, judges amount of infusion, and utilize the medical fluid surplus y of remote controler setting infusion bottle, the calculation formula of medical fluid surplus y are as follows:
Wherein, m0For known infusion bottle quality, a is alarm threshold value；Here a is alarm threshold value, and alarm threshold value is arranged It is to alarm before the infusion operation of setting is completed, prevent showing for blood back after infrared remote control determines amount of infusion As ensure that the safety of patient.
Then micro-control unit 2 compares the y value being calculated with the medical fluid margin value of setting, if y value is less than or waits In the medical fluid margin value of setting, micro-control unit 2 controls sound and light alarm module and issues sound and light alarm signal；Otherwise continue medicine The monitoring of liquid surplus.For example, set medical fluid margin value as 1/3 using IR remote controller, i.e., 2/3 amount of a defeated bottle liquid medicine, by y value with 1/3 compares in real time, and as y≤1/3, micro-control unit 2 will send alarm command to PWM controller, and PWM controller controls again to be referred to Show 7 flashing red light of lamp, while controlling audible alarm and making a sound alarm, reminds patient and medical staff.It is not less than in y value and sets When fixed medical fluid margin value, indicator light 7 is in the long state that gives a green light, and audible alarm does not work.
In infusion process (before infusion does not complete), micro-control unit 2 simultaneously monitors transfusion speed in real time, method Specifically: micro-control unit 2 calculates real-time transfusion speed v, calculation formula are as follows:
Medical staff presets transfusion speed model using remote controler according to the different demands of the different patients of all ages and classes It encloses, when micro-control unit 2 compares the transfusion speed v being calculated with the transfusion speed range of setting, if v value is beyond setting Transfusion speed range, micro-control unit 2 control sound and light alarm module issue sound and light alarm signal, prompting carry out speed regulation processing； Otherwise continue transfusion speed monitoring.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited In specific details.
