Description

A kind of intelligent transfusion system

Technical field

The present invention relates to medical instruments field, particularly relate to a kind of intelligent transfusion system.

Background technology

Transfusion, particularly venous transfusion is the conventional means in the medical treatment, and the used transfusion device of infusing adopts packed form or bottled form mostly, adopts based on the input mode of gravity sample introduction or external syringe pump and realizes transfusion.In the process of transfusion, medical personnel or patient will nurse the residue situation of the medicinal liquid of transfusion device inside at any time, in order to avoid because of the medicinal liquid deficiency, in time do not change dressings or stop injection and cause accident.And because existing transfusion system, often need the professional health care personnel to stop transfusion or change liquid operation, therefore, in the numerous hospital of patient, develop a kind of intelligent infusion set of automatization, for the workload that reduces medical personnel located either, improve medical care efficient and alleviate patient's psychological burden significant.

Summary of the invention

The objective of the invention is the deficiency at existing infusion techn, a kind of intelligent transfusion system is provided.It is characterized in that this transfusion system only need set infusion program simply and can finish all infusion process automatically before transfusion, and finish prerequisite for alert service closing on transfusion, be used for reminding finishing of medical personnel's transfusion.

For achieving the above object, the present invention realizes by the following technical solutions: transfusion system is made up of drug solution storage device, conduit, transfusion device, fluid-delivery valve, liquid level sensor, controller and alarm.The liquid level information of its operation principle for providing based on liquid level sensor, transfusion device and fluid-delivery valve are carried out the control of program by controller, realization comprises the control that transfusion time, flow velocity and stream switch, and drug solution is intelligently imported patient's vein realize therapeutic effect to realize sampling device.

Drug solution storage device of the present invention can be plastic bag, also can be vial, and namely the file layout of drug solution can be packed or bottled form.

Conduit of the present invention can be elastic macromolecular material conduit, also can be the conduit of hard.For example can be silica gel tube, also can be PEEK pipe or polyfluortetraethylene pipe.

Infusion pump of the present invention can be the gravity transfusion device, also can be external pump transfusion device.When adopting the gravity transfusion device, packed or bottled drug solution can be hung on the fixing rack platform, and when adopting pump use transfusion device, need first drug solution is installed in the syringe, devices such as reuse syringe pump are infused.

Fluid-delivery valve of the present invention can be one or more electromagnetic valve group, controls the break-make of different streams respectively.The control of different electromagnetic valves is carried out by controller, and when a certain medication infusion, then the stream of other kinds medicine is in off state.

Liquid level sensor of the present invention can be optical pickocff, also can be electrochemical sensor, is used for the surplus of monitoring drug solution.More specifically, liquid level sensor can place the drug solution storage device, also can place the infuse front end of injection position close to the patient, and its purposes is whether the drug solution in this stream of perception will soon have flowed.

Controller of the present invention is made of single chip machine controlling circuit, and the signal that is used for liquid level sensor is obtained carries out acquisition process, and the sequencing work of control transfusion device and fluid-delivery valve.

Alarm of the present invention can be voice guard or visual alarm, is used for informing that transfusion closes to an end, and then stops transfusion by medical personnel or patient.

This cover intelligent transfusion system that the present invention proposes, can realize the whole transfusion process of intelligent control, adopt pre-set working procedure, whole infusion process need not patient or the real-time manual monitoring of medical personnel located either, greatly increase work efficiency, have extremely important using value and meaning in the medical diagnosis field.

Specific embodiments

The following examples will give further instruction to the present invention, but not thereby limiting the invention.

The system of a kind of intelligent transfusion system forms as shown in Figure 1, its operation principle is the drug solution that is stored in the medicament storage device, be connected with infusion pump by conduit, infusion pump further enters medicine at last in patient's body and realizes therapeutic effect by the conduit fluid-delivery valve of flowing through.Wherein, liquid level sensor monitor at any time drug solution surplus and with this information instantaneous transmission to controller, controller can be controlled the flow velocity of infusion pump on the one hand, can or close according to the unlatching of electromagnetic valve in the medicament level information control different pharmaceutical stream on the other hand, thus program finish the transfusion of all medicines.Especially, when closing on last a kind of medication infusion and finish, alarm is reported to the police automatically and is informed patient or medical and nursing work personnel, finishes transfusion.
