Description

Technical Field

[0001] This utility model relates to the field of peritoneal dialysis technology, and in particular to a disposable peritoneal dialysis drainage bag. Background Technology

[0002] Peritoneal dialysis utilizes the peritoneum's semi-permeable membrane properties. Prepared dialysate is regularly and periodically infused into the patient's peritoneal cavity via a catheter, driven by gravity. Due to the concentration gradient of solutes across the peritoneum, solutes with higher concentrations move to lower concentrations (diffusion), while water moves from the hypotonic side to the hypertonic side (osmosis). Through continuous replacement of the peritoneal dialysis fluid, the goal is to remove metabolic waste products and toxic substances from the body, and correct water and electrolyte imbalances.

[0003] Peritoneal dialysis requires the use of drainage bags, but existing peritoneal dialysis drainage bags cannot effectively expand their storage space during use, thus hindering effective drainage and reducing their fluid storage and drainage efficiency. Furthermore, they cannot provide timely reminders when the bag is full, further reducing their usage and warning efficiency. Therefore, we propose a disposable peritoneal dialysis drainage bag. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a disposable peritoneal dialysis drainage bag that can effectively expand the storage space, thereby enabling effective drainage, improving its fluid storage efficiency and drainage efficiency, and providing timely reminders when it is full, thus improving its usage efficiency and warning efficiency.

[0005] To achieve the above objectives, a disposable peritoneal dialysis drainage bag is provided, comprising: an outer bag body, an inner bag body disposed within the outer bag body, a bonding plate connected to the top of the outer bag body, and a connecting pipe connected to the top of the bonding plate, the bottom end of the connecting pipe extending sequentially through the bonding plate and the top of the outer bag body into the inner bag body, and several evenly spaced drainage holes being provided on the left and right sides near the top of the inner bag body.

[0006] According to the disposable peritoneal dialysis drainage bag, the top and bottom of the inner bag body are respectively connected to the top and bottom of the inner cavity of the outer bag body, and the front and rear outer walls of the inner bag body are respectively connected to the front and rear inner walls of the outer bag body.

[0007] According to the disposable peritoneal dialysis drainage bag, a fastening ring is fitted around the outside of the connecting tube near the top, and fastening screws are respectively provided on the left and right sides of the fastening ring.

[0008] According to the disposable peritoneal dialysis drainage bag, L-shaped guide plates are connected to the outer walls of the left and right sides of the inner bag near the top, and floats are movably connected between the side walls of the L-shaped guide plates and the inner walls of the outer bag. A marker rod is connected to the top of the float, and a groove matching the marker rod is opened on the top of the inner cavity of the outer bag. Several evenly distributed buoyancy balls are connected to the bottom of the float.

[0009] According to the disposable peritoneal dialysis drainage bag, the left and right sides of the outer bag are connected to hanging rings along the front and back directions near the top.

[0010] According to the disposable peritoneal dialysis drainage bag, sliders are connected to the left and right sides of the float plate, and grooves matching the sliders are respectively opened on the side wall of the L-shaped guide plate and the inner wall of the outer bag body.

[0011] The above solution has at least one of the following beneficial effects: This technical solution, through the cooperation between components such as L-shaped guide plate, float plate, buoyancy ball, marker rod and through groove, enables it to effectively expand the storage space, thereby enabling it to effectively guide the flow, improving its liquid storage efficiency and flow guiding efficiency, and can provide timely reminders when it is full, improving its usage efficiency and warning efficiency.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figures 1 to 4 This utility model embodiment of a disposable peritoneal dialysis drainage bag includes an outer bag body 1. Hanging rings 8 are connected to the left and right sides of the outer bag body 1 near the top along the front-back direction. An inner bag body 9 is provided inside the outer bag body 1. A bonding plate 2 is connected to the top of the outer bag body 1, and a connecting pipe 3 is connected to the top of the bonding plate 2. The bottom end of the connecting pipe 3 extends through the bonding plate 2 and the top of the outer bag body 1 to the inner bag body 9. Several evenly distributed liquid outlet holes 10 are opened on the left and right sides of the inner bag body 9 near the top. A fastening ring 4 is fitted on the outside of the connecting pipe 3 near the top, and fastening screws 5 are respectively provided on the left and right sides of the fastening ring 4.

[0021] The top and bottom of the inner bag 9 are connected to the top and bottom of the inner cavity of the outer bag 1, respectively, and the front and rear outer walls of the inner bag 9 are connected to the front and rear inner walls of the outer bag 1, respectively. This structure allows for effective expansion of the storage space, thereby enabling effective flow guidance and improving its liquid storage and flow guidance efficiency.

[0022] L-shaped guide plates 11 are connected to the outer walls of the inner bag 9 near the top on both sides. A float plate 13 is movably connected between the side wall of the L-shaped guide plate 11 and the inner wall of the outer bag 1. An indicator rod 6 is connected to the top of the float plate 13, and a slot 7 matching the indicator rod 6 is provided on the top of the inner cavity of the outer bag 1. Several evenly distributed buoyancy balls 12 are connected to the bottom of the float plate 13. Slider blocks 14 are connected to the left and right sides of the float plate 13, and grooves 15 matching the sliders 14 are provided on the side wall of the L-shaped guide plate 11 and the inner wall of the outer bag 1. This structure allows for timely reminders when the bag is full, improving its usage efficiency and warning efficiency.

[0023] Working principle: In use, this technical solution is first hoisted using the lifting ring 8 and connected to the external pipeline via the connecting pipe 3. Then, the fastening screw 5 is tightened for secure installation. Subsequently, the liquid flows into the inner bag 9 through the connecting pipe 3. When the inner bag 9 is full, the liquid flows out through the liquid outlets 10 on both sides into the space formed by the inner bag 9 and the outer bag 1, effectively expanding the storage space and thus effectively guiding the flow, improving its liquid storage efficiency and flow guiding efficiency. As the liquid increases, the buoyancy ball 12 and the float plate 13 slide upward between the side wall of the L-shaped guide plate 10 and the inner wall of the outer bag 1. The float plate 13 drives the indicator rod 6 upward through the slot 7 to extend to the outside of the outer bag 1, providing timely reminders when the bag is full, thus improving its usage efficiency and warning efficiency.
