Detailed Description
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
The present invention will be further explained with reference to the accompanying drawings.
Example 1
As shown in fig. 1-3, the novel dialysate storage device provided in this embodiment includes a bag 1, a handle 2 disposed above the bag, and a connector 3 disposed below the bag and located at the bottom of the bag.
The joint comprises a one-way valve 6, a filter element 5, a sealing plug 7 and a tail end plugging piece 8 which are sequentially detachably connected. The end plugging piece is a pull ring.
The check valve includes a first connector 601, a second connector 602, a valve sleeve 605, and a valve core 606. The first joint and the second joint are hollow structures, and the first joint and the second joint are assembled to form a valve cavity 604. The valve sleeve is of an umbrella-shaped structure and comprises umbrella rib parts and an annular plate, gaps exist among the umbrella rib parts, and the valve sleeve is fixed at the joint of the first joint and the second joint through the annular plate.
The valve core comprises a conical part and a clamping ring part, the conical part is assembled on the rib part of the umbrella, the clamping ring part is contacted with the annular plate, and the lower part of the valve core is connected with the inner surface of the second connector through an elastic piece 607.
Under the action of the elastic piece, the conical part of the valve core is separated from or attached to the umbrella rib part of the valve sleeve. The liquid in the bag body is separated from the valve sleeve under the action of gravity, the liquid flows into the second joint through the gap of the rib part of the umbrella and enters the filter element through the second joint for filtration, and then flows into the liquid suction rod of the dialysis machine through the needle head 4 which punctures the sealing plug. Because of the elasticity of the elastic piece, when the pressure generated by the liquid in the bag body can not reach the opening pressure of the one-way valve, the liquid can not flow out any more, thereby controlling the one-way flow of the liquid and preventing the backflow phenomenon.
The first joint and the second joint outer wall set up cutting ferrule 603, and cutting ferrule fixed assembly first joint and second connect, realize good location effect.
The bag body is made of 3-5 layers of co-extruded films made of polyethylene PE or polypropylene PP.
