Problems solved by technology

[0003] Existing electronic infusion pumps generally require the operator to press the exhaust button for a long time to exhaust. During the exhaust process, the button must be kept pressed, which makes the operator prone to fatigue, and the length of the exhaust time is also based on experience. risk

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:

[0034] See figure 1 , The present invention relates to an electronic infusion pump, and its preferred embodiment includes a microprocessor, an input module, a liquid pump module and a bubble detector.

[0035] The input module is used to enter the exhaust volume; the exhaust volume can be the displacement volume. The input module can be a keyboard or a touch screen.

[0036] see figure 2 , at present, the liquid storage container 10 is generally connected to the infusion needle through the self-contained pipeline 12 of the electronic infusion pump. Part of the pipeline on one side of the liquid container is the squeeze pipeline 11 . The operator only needs to set the exhaust volume not less than the length of the total pipeline according to the actual situation.

[0037] The air bubble detector is used to detect air bubbles in the squeeze pipe...

Abstract

The invention provides an electronic infusion pump and an exhaust control method. The electronic infusion pump comprises a microprocessor, an input module, a pumping module and a bubble detector. The input module is used for inputting an air displacement. The bubble detector is used for detecting bubbles in an extrusion pipe. The microprocessor is used for driving the extrusion pipe to discharge a liquid via the pumping module, and determining whether bubbles are detected by the detector, controlling the pumping module to drive the extrusion pipe to discharge a corresponding amount of soup according to the air displacement, to exhaust the bubbles out of a main pip if the bubbles are detected by the detector, otherwise, determining whether the present air displacement reaches up to the air displacement, and stop driving the pumping module to stop exhausting if the present air displacement reaches up to the air displacement, otherwise, continuing to detect whether bubbles are detected by the detector. By adopting the electronic infusion pump and the exhaust control method, an operator only need to set an air displacement, bubbles in the extrusion pipe can be automatically exhausted out of the main pipe, no worker needs to watch over the exhausting process, so the electronic infusion pump is convenient to operate, safe and reliable, and high in intelligence.

Description

technical field [0001] The invention relates to an electronic infusion pump and an exhaust control method thereof. Background technique [0002] The electronic infusion pump is used in conjunction with the medicine box storing the medicine liquid. Since the medicine liquid is injected into the medicine box, a certain amount of air will be brought in more or less, so it is necessary to discharge the air mixed in the medicine liquid before the infusion to avoid the risk of air embolism. . [0003] Existing electronic infusion pumps generally require the operator to press the exhaust button for a long time to exhaust. During the exhaust process, the button must be kept pressed, which makes the operator prone to fatigue, and the length of the exhaust time is based on experience. risk. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention aims to provide an electronic infusion pump and its exhaust control method that can solve t...
