Abstract
The invention discloses an extrusion type infusion pump and an infusion method thereof. The infusion pump comprises an infusion pipe, an extrusion device and a driving device. One end of the infusion pipe is provided with a needle. The extrusion device comprises two extrusion surfaces cooperated with each other. The infusion pipe passes through the space between the two extrusion surfaces and is drawn by the driving device to move, therefore, when the two extrusion surfaces extrude the infusion pipe, liquid in the infusion pipe is output from the needle. According to the invention, the liquid medicine is filled in the infusion pipe, and the micro-scale and accurate infusion can be realized under the extrusion to the infusion pipe, thereby obviously improving the infusion precision and reducing the cost of a high-accuracy infusion pump. The extrusion type infusion pump can replace existing high-accuracy infusion pumps and greatly reduce the expenditure of common patients on medical treatment, is conveniently used and can satisfy different infusion requirements during the medical treatment.

Described driving device comprises motor and recycling round at least, and described motor drives described recycling round, and the other end of described tube for transfusion is fixed on the recycling round, is wrapped on the recycling round after making tube for transfusion pass two compressive planes of pressurizing unit.
Preferably, also comprise the tube for transfusion conveyer device, described tube for transfusion conveyer device is connected with motor, and described tube for transfusion passes between two compressive planes of pressurizing unit after by the carrier pipe conveyer device again.
In the above-mentioned squash type infusion pump, the other end of described tube for transfusion is marked with medicinal liquid for sealing in the described tube for transfusion.
In the another kind of mode, described tube for transfusion is a vacuum tube, and its needle end is provided with valve, and the other end is sealing.
In the another kind of mode, the other end of described tube for transfusion is provided with air bag.
Preferably, the circumferential surface of described two running rollers is provided with pitch wheel.
A kind of squash type infusion method that the present invention proposes is achieved through the following technical solutions: the tube for transfusion that will fill medicinal liquid passes between two compressive planes of pressurizing unit,, at least one compressive plane makes the tube for transfusion pressurized by being exerted pressure, thereby make the medicinal liquid in the tube for transfusion export, move by driving device traction tube for transfusion simultaneously from syringe needle.
As a kind of embodiment of said method, the tube for transfusion of filling medicinal liquid is passed between the circumferential surface contact position of two running rollers, push tube for transfusion by the relative rotation of two circumferential surfaces, thereby make medicinal liquid export from syringe needle.
Preferably, in the said method, move thereby drive recycling round rotation traction tube for transfusion by motor.
Preferably, in the said method, before the transfusion, the air bag that is located at the tube for transfusion other end by extruding sucks medicinal liquid in the tube for transfusion from needle end.
Another is preferred, in the said method, before the transfusion, by the valve of opening vacuum tube for transfusion needle end medicinal liquid is sucked in the tube for transfusion.
The present invention is compared with the prior art the beneficial effect that is had: with liquid medicine filling in tube for transfusion, realize trace and accurately transfusion by extruding to tube for transfusion, because the diameter of tube for transfusion is other medical liquid containers relatively, especially significantly reduce with respect to existing piston formula syringe, can significantly improve the transfusion precision, the cost of simplified structure, reduction high-precision infusion pump, thus existing high accuracy infusion set can be replaced, significantly reduce the medical expense of general patient.Adopt two counterrotating running rollers that tube for transfusion is pushed, also can adjust the speed of transfusion, make things convenient for the diagnosis and treatment medical treatment by the rotating speed of adjusting running roller.And all control easily of the size of running roller and tube for transfusion, less demanding to technology, infusion pump simple in structure, flow speed control is accurate, is convenient to manufacture and design, and is easy to promote the use of.The tube for transfusion inner liquid medicine can fill when dispatching from the factory, the convenient use; Also can infuse and use preceding imbibition, conveniently produce, reduce cost, satisfy the different needs that use.During transfusion, tube for transfusion moves, and is disposable to the extruding of some positions of tube for transfusion, can not repeat to push the same position of tube for transfusion, avoids because the tube for transfusion fatigue damage causes transfusion to lose efficacy.
