Be compared with the prior art, the beneficial effect that the present invention has is: built-in infusion process table in infusion set, control unit control medical pump comes work according to the setup parameter of transfusion table, according to patient's body constitution and drug type, make infusion flow rate from slowly to fast or near slowly, process is finished automatically, need not manual adjustment, reduce medical personnel's workload, convenient and reliable.Transfusion speed can accurately be controlled, and improves the effect of transfusion and input medicine, reduces or avoids transfusion and input medicine complication, reduces poisonous side effect of medicine.Such as in input during anesthetis, can prevent from patient's cental system, blood circulation or respiratory system caused to cause damage; When the input insulin, avoid the various sequela that cause that hypoglycemia causes.Be provided with user interface, in infusion process, can adjust infusion parameter at any time, to make things convenient for needs of medical treatment.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Fig. 2 is transfusion speed adjustment process figure in the specific embodiment of the invention.
The specific embodiment
A kind of variable speed infusion device as shown in Figure 1 comprises TIP 1, control unit 3, medical pump 5.Control unit 3 is provided with timing module 7, memory module 6, and is provided with user interface 2 and output interface 4.Store the infusion process table in the memory module 6.User interface 2 is connected with TIP 1, is used to receive operator's control instruction.Medical pump 5 is infusion pump, syringe pump, anesthesia pump, analgesic pump, insulin pump or nutrition pump, and medical pump 5 receives the control signal of output interface 4 outputs of control units, changes transfusion speed to human body by changing running parameter.
The infusion method of said apparatus is described in order to the infusion process of holder monarch drug thing below, and it may further comprise the steps:
A) control unit 3 reads the parameter in a transfusion stage of infusion process table.
Built-in infusion process table in the memory module 6 of infusion set, this infusion process table is divided into seven transfusion stages to the infusion process of ritodrine medicine, and each transfusion stage comprises persistent period and two parameters of infusion flow rate of transfusion.As shown in Table 1.
Table one:
| Transfusion stage numbering | The transfusion persistent period (min) | Infusion flow rate (ml/h) |
| 1 | 10 | 15 |
| 2 | 10 | 30 |
| 3 | 10 | 45 |
| 4 | 10 | 60 |
| 5 | 10 | 75 |
| 6 | 10 | 90 |
| 7 | When unlimited | 105 |
After entering the special-purpose infusion mode of ritodrine, control unit reads the parameter in first transfusion stage of the infusion process table that is stored in the memory module 6.
B) control unit 3 is given medical pump 5 according to the speed parameter output control signal in the transfusion stage of reading, and medical pump is infused to the patient, and the time parameter in the transfusion stage that while control unit 3 bases read starts timer and picks up counting.
Control unit 3 is according to the speed parameter in first transfusion stage, and the rotating speed of control ritodrine infusion pump makes infusion flow rate remain on 15ml/h, and starts timing module 7 timing, makes for the first transfusion stage continue 10min.
C) when timer timing during to the setting value of time parameter, control unit reads the parameter in the next one transfusion stage of infusion process table, and repeats step b).
By above step can control infusion set when carrying the ritodrine medicine according to from carrying out to fast speed slowly, both reduced workload, also guarantee the degree of accuracy of regulating.
Further, in infusion process, under any flow velocity, can pass through TIP 1 input control order, change infusion flow rate, thereby satisfy different needs of medical treatment.As described in the step b), when control unit 3 detects the control instruction of user interface 2, then give medical pump 5, as increasing or reduce transfusion speed, keep current transfusion speed, stop transfusion etc., and stop the timing of timing module 7 according to the speed parameter of control instruction output control signal.For increasing or reducing infusion flow rate, can carry out according to Fig. 2.
When needs are changed medicine bottle or suspended transfusion, can pass through control panel 1 input control order.When control unit 3 detected the time-out transfusion control instruction of user interface 2, the output control signal stopped medical pump 5 operations, and the timing of time out module 7.Subsequently, when control unit detected the recovery transfusion control instruction of user interface 2, the output control signal started medical pump 5 operations, and startup timing module 7 continues timing.
Should be noted that to be provided with other different parameters in the infusion process table, such as the amount of infusion in each stage.In each transfusion stage, control unit writes down the amount of infusion in this transfusion stage, when the amount of infusion setting value in the amount of infusion arrival infusion process table in this transfusion stage, control unit reads the parameter in the next one transfusion stage of infusion process table again, enters next transfusion stage.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
