Description
Technical field
The present invention relates to a kind of depassing unit, especially relate to the depassing unit in a kind of hemodialysis apparatus.
Background technology
Hemodialysis apparatus comprises water treatment system, mixes water for dialysis and dialyses the mixing arrangement of using concentrated solution, equipment and other auxiliary facilities of passing through artificial kidney pump dialysis solution.
Water for dialysis be ordinary tap water successively through filtration, softening, activated carbon adsorption and reverse osmosis process the reverse osmosis water that forms.Dialysis is divided into concentrated solution A and concentrated solution B two classes with concentrated solution, and wherein, concentrated solution A contains the compositions such as sodium chloride, potassium chloride, calcium chloride, magnesium chloride and glucose; Concentrated solution B is mainly sodium bicarbonate.Water for dialysis and dialysis solution concentrated solution are fully mixed through mixing arrangement by a certain percentage, be made into the dialysis solution of final working concentration.
In hemodialysis apparatus, require to have bubble in dialysis solution.Except adding special moisture separator, can also liquid add the depassing unit that is captured in gas in liquid on the road, to guarantee in dialysis solution without gas.
In existing hemodialysis apparatus, the general side liquid in-out that adopts from depassing unit, and liquid is the mode of directly advancing directly to go out, and has following defective:
When 1, flow rate of liquid was larger, the depassing unit middle water level was not steady, caused depassing unit to stay incessantly gas, and gas is followed liquid with bubble form and discharged from liquid outlet;
2, all be arranged on the side of depassing unit due to inlet and liquid outlet, for the hemodialysis apparatus of vertical formula layout, take up space large, and be not easy to install and use.
Summary of the invention
The present invention proposes the depassing unit in a kind of hemodialysis apparatus, adopts bottom liquid in-out and top to give vent to anger, and has liquid stream characteristics stably.
The present invention adopts following technical scheme to realize: a kind of depassing unit for hemodialysis apparatus, and it comprises: vertically disposed urceolus; Be arranged on gas outlet and at least one detector for detection of the urceolus inside liquid level on the urceolus top cover; Be arranged on inlet and liquid outlet on the urceolus bottom; Arrange one in urceolus inside and connect respectively the anti-stiff of inlet and liquid outlet.
Wherein, anti-stiff comprising: be arranged on anti-stiff upper several inclined holes that are connected with the inlet perforation; Be arranged on anti-stiff upper several straight holes that are connected with the liquid outlet perforation; Be arranged on the error-proof structure on anti-stiff downside.
Wherein, error-proof structure comprises the first projection and the second projection vertically is set have certain distance between the first projection and the second projection and form locating slot, and locating slot wherein the width of an end greater than the width of the other end.
Wherein, the urceolus lateral surface has fixed part.
Compared with prior art, the present invention has following beneficial effect:
The depassing unit that the present invention proposes adopts the bottom liquid in-out, realized little cavity at flow rate of liquid the level stability during greater than 1.5L/ minute, have better degassing effect.In addition, the depassing unit of the present invention's proposition has advantages of simple in structure.

The specific embodiment
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, the depassing unit that the present invention proposes comprises: vertically disposed cylindric urceolus 10, and it is outside connects and is provided for urceolus 10 is fixed on fixed part 15 on other objects; A gas outlet 11 and at least one detector 14 for detection of urceolus 10 inside liquid level height are set on the top cover of urceolus 10, inlet 12 and liquid outlet 13 are set on the bottom of urceolus 10; And the bottom in urceolus 10 arranges one and connects respectively anti-stiff 16 of inlet 12 and liquid outlet 13.
Wherein, prevent on stiff 16, several inclined holes 161 being set, and several straight holes 162, and several inclined holes 161 and inlet 12 maintenance perforations, and keep perforation between several straight holes 162 and liquid outlet; The middle part of anti-stiff 16 downside arranges error-proof structure, described error-proof structure comprises the first projection 163 and the second projection 164 vertically is set, have certain distance between the first projection 163 and the second projection 164 and form locating slot, and the locating slot wherein width of an end greater than the width of the other end, makes to install can not be arranged on errors present at anti-stiff 16 o'clock.
Owing to preventing that stiff 16 separate inlet 12 and liquid outlet 13, the liquid of inlet 12 enters the inside of urceolus 10 from inclined hole 161, and then liquid flows out urceolus 10 from straight hole 162 through liquid outlets 13; If have bubble from the liquid that inlet 12 flows into, after entering urceolus 10 inside, because bubble has lighter density, bubble will rise urceolus 10 is inner, thereby it is inner and can be along with liquid flows out from liquid outlet 13 to stay urceolus 10.
Along with the increase of urceolus 10 internal gas, the liquid level of urceolus 10 inside will descend, when the end probe of detector 14 can't detect liquid level, with the air scavenge of urceolus 10 inside.The environment for use different according to depassing unit can adopt malleation degasification or negative pressure degasification.
In conjunction with shown in Figure 4, be the annexation schematic diagram of each equipment in the application example of malleation degasification.The malleation degasification generally is applied in the dialysis solution liquid feeding pipeline.Solution feed pump is sent into urceolus 10 inside with dialysis solution from inlet 12 under the positive pressure greater than 0.5 newton.When the end probe of detector 14 can detect liquid level, be connected to the closed electromagnetic valve of gas outlet 11; When the end probe of detector 14 can't detect liquid level, the electromagnetic valve that is connected to gas outlet 11 upper pipelines is opened, the gas of urceolus 10 inside is 11 discharges from the gas outlet under positive pressure, the liquid level of urceolus 10 inside rises, the shut electromagnetic valve in the time of again can liquid level being detected until the end of detector 14 is popped one's head in.
In conjunction with shown in Figure 5, be the annexation schematic diagram of each equipment in the application example of negative pressure degasification.The negative pressure degasification generally is applied in the dialysis fluid circuit pipeline.Liquid outlet 13 connects Pump for giving-out, and Pump for giving-out is extracted dialysis solution out with certain pressure from urceolus 10 is inner, thereby makes inlet 12 have certain negative pressure.When the end probe of detector 14 can detect liquid level, close the electromagnetic valve and the air pump that are connected to gas outlet 11 upper pipelines; When the end probe of detector 14 can't detect liquid level, electromagnetic valve is opened the air pump that is connected with electromagnetic valve and is started working, gas 11 extractions from the gas outlet with urceolus 10 inside, the liquid level of urceolus 10 inside rises, until the end of detector 14 is popped one's head in shut electromagnetic valve in the time of again can liquid level being detected and air pump is quit work.
The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
