Problems solved by technology
[0006] 1. When the liquid flow rate is large, the water level in the degassing device is not stable, so that the degassing device cannot retain the gas, and the gas follows the liquid from the liquid outlet in the form of bubbles discharge;
[0007]2. Since the liquid inlet and the liquid outlet are both arranged on the side of the degassing device, for hemodialysis equipment with a vertical layout, it takes up a lot of space, and Not easy to install and use

The invention discloses a degassing device for hemodialysis equipment, which comprises: an outer cylinder (10) arranged vertically; an air outlet (11) arranged on the top cover of the outer cylinder (10) and at least one for detecting the outer cylinder (10) The detector (14) of the internal liquid level; the liquid inlet (12) and the liquid outlet (13) are arranged on the bottom cover of the outer cylinder (10); (12) and the anti-fogging plate (16) of the liquid outlet (13). The degassing device proposed by the present invention adopts the liquid in and out at the bottom, realizes the stable liquid level of the small cavity when the liquid flow rate is greater than 1.5L / min, has good degassing effect, and has a simple structure.
Description
technical field [0001] The invention relates to a degassing device, in particular to a degassing device in hemodialysis equipment. Background technique [0002] Hemodialysis equipment includes water treatment systems, mixing devices for mixing dialysis water and dialysis concentrates, equipment for pumping dialysis fluid through artificial kidneys, and other auxiliary equipment. [0003] The dialysis water is the reverse osmosis water formed by filtering, softening, activated carbon adsorption and reverse osmosis treatment of ordinary tap water in sequence. The concentrated solution for dialysis is divided into two types: concentrated solution A and concentrated solution B. Among them, concentrated solution A contains sodium chloride, potassium chloride, calcium chloride, magnesium chloride and glucose; concentrated solution B is mainly sodium bicarbonate. The dialysis water and the dialysate concentrated solution are fully mixed in a certain proportion through the mixing...
