Description

Technical Field

[0001] The present invention relates to the technical field related to the treatment of peritoneal dialysis waste liquid, and specifically, to a peritoneal dialysis waste liquid treatment device. Background Art

[0002] Peritoneal dialysis fluid is a special liquid used for peritoneal dialysis, and its main function is to remove metabolic wastes and excess water from the body through the peritoneum. Peritoneal dialysis fluid can excrete metabolic wastes such as urea and creatinine in the blood through the peritoneum; utilize the osmotic pressure difference to remove excess water in the body; and help stabilize the electrolyte and acid-base levels in the body.

[0003] Under normal circumstances, peritoneal dialysis waste liquid does not contain germs and viruses, but when the user is ill, peritoneal dialysis waste liquid may contain germs, especially during peritonitis or other infections. Therefore, attention needs to be paid to preventing infection when treating peritoneal dialysis waste liquid.

[0004] The patent document "A peritoneal dialysis waste liquid treatment device for nephrology department" with the Chinese application number CN202120308308.8 discloses a peritoneal dialysis waste liquid treatment device for nephrology department. A bag containing liquid is placed between a rectangular plate and a partition plate. The rectangular plate moves downward, and the needle on the rectangular plate will pierce the bag, and the liquid in the bag will be squeezed out under the extrusion of the rectangular plate and the partition plate.

[0005] However, the above patent still has the following deficiencies. Medical bags mostly use medical-grade plastic soft bags. After the needle pierces a notch in the bag, the needle will fill the notch, and the side wall of the notch will adhere to the needle, thereby hindering the discharge of the liquid in the bag. The liquid discharge speed is slow and the efficiency is low. Moreover, during the extrusion process, the liquid will also splash onto the inner wall of the box, causing pollution.

[0036] The following will describe in detail the specific implementation mode of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation mode described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] In the present invention, unless otherwise stated, the orientation words contained in terms such as "upper, lower, inner, outer" only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation of the term.

[0038] As Figure 1-9 shown, a peritoneal dialysis waste liquid treatment device includes: a housing 2 with a cabinet door 1 provided on its side wall, a top plate 5 assembled on the top of the housing 2 and provided with a first window 3 and a second window 4, a horizontal mounting plate 7 assembled on the inner wall of the housing 2 through a first mounting bracket 6, a squeezing unit assembled on the mounting plate 7 and located directly below the first window 3, at least one ultraviolet lamp 8 assembled on the inner wall of the housing 2, a cover plate mechanism assembled on the lower surface of the top plate 5 for covering the first window 3 and the second window 4, and a waste bag barrel 9 located inside the housing 2 and directly below the second window 4;

[0039] The squeezing unit includes a vertical limiting plate 10, an extrusion plate 11 arranged parallel to the limiting plate 10 and capable of moving close to the limiting plate 10, and a plurality of hollow conical parts 12 assembled at intervals on the extrusion plate 11 with their tips facing the limiting plate 10. The limiting plate 10 is provided with first avoidance holes 13 corresponding to the plurality of conical parts 12 one by one. The end of the conical part 12 away from the limiting plate 10 is open, and a plurality of liquid passage grooves 14 communicating with the inside are arranged on the side wall of the conical part 12.

[0040] In the above technical solution, when in use, the cover mechanism opens to expose the first window 3 and the second window 4, and the bag filled with liquid is placed in the squeezing unit through the first window 3, and will fall in front of the squeezing plate 11 and the limit plate 10, and then the cover mechanism starts to cover the first window 3 and the second window 4, the squeezing unit starts, and the squeezing plate 11 moves close to the limit plate 10 until the cone 12 penetrates the bag. After the end of the cone 12 penetrates the bag, the liquid in the bag will be discharged into the interior of the cone 12 through the liquid passage 14, and then discharged through the open end of the cone 12. The drainage speed is fast. As the liquid is continuously discharged, the distance between the squeezing plate 11 and the limit plate 10 gradually decreases until the liquid in the bag is discharged and becomes a waste bag, and then the squeezing plate 11 moves away from the limit plate 10 and returns to its original position.

[0041] After the squeezing unit squeezes out the liquid in the bag, the ultraviolet lamp 8 starts to emit several beams of ultraviolet light, thereby disinfecting the inside of the shell 2 and the waste bag to prevent the spread of contagious viruses and bacteria contained in the liquid. After disinfection, the waste bag can be taken out and put into the waste bag bucket 9. The ultraviolet lamp 8 can also be turned on at the same time during the startup process of the squeezing unit. The shell 2 and the cover mechanism can prevent ultraviolet rays from irradiating the external space, which is highly safe.

[0042] In a preferred embodiment of the invention, an upwardly inclined tube sleeve 15 is mounted on the outer wall of the shell 2, and a first through groove corresponding to the tube sleeve 15 is provided on the outer wall of the shell 2. A clamp 16 can be plugged in and out of the tube sleeve 15, and a seal 17 that can fit and abut against the inner wall of the tube sleeve 15 is fixedly mounted on the clamp 16.

[0043] In the above technical solution, the clamp 16 is an existing mature technology, so its structure and working principle are not explained in this article. The operator can put the waste bag into the waste bag bucket 9 through the clamp 16 without touching the waste bag, which further improves the safety of use; and the end of the clamp 16 will extend into the interior of the shell 2 through the tube kit 15, and can be disinfected together during disinfection.

[0044] In a preferred embodiment of the invention, the extrusion unit further includes a splash-proof box 18 whose bottom is fixedly mounted on the upper surface of the mounting plate 7 and whose top and bottom are open, and a horizontal moving mechanism mounted on the mounting plate 7 and whose moving end is connected to the limit plate 10. The extrusion plate 11 is located on the inner side of the splash-proof box 18, and the limit plate 10 is fixedly mounted on the inner wall of the splash-proof box 18.

[0045] The mounting plate 7 is provided with a plurality of liquid drain grooves 19 all located inside the splash-proof box 18 . The bottom of the mounting plate 7 is equipped with a liquid receiving mechanism sleeved on the outside of the plurality of liquid drain grooves 19 .

[0046] In the above technical solution, the bag filled with liquid input from the first window 3 will fall downward into the splash-proof box 18, and the horizontal moving mechanism will drive the pressing plate 11 to move closer to the limiting plate 10, and the liquid extruded from the bag will flow into the liquid receiving mechanism through the liquid discharge through groove 19.

[0047] In a preferred embodiment of the invention, the horizontal moving mechanism includes a pair of mounting seats arranged at intervals and both assembled on the mounting plate 7 through mounting arms 20, a first guide rod 21 with both ends fixedly connected to the corresponding mounting seats respectively, a threaded rod 22 with both ends pivotally connected to the corresponding mounting arms 20 through shaft seats and parallel to the first guide rod 21, a first connecting frame 23 fixedly connected to the pressing plate 11, a threaded sleeve 24 fixedly connected to the first connecting frame 23 and threadedly sleeved on the threaded rod 22, a first sliding sleeve 25 fixedly connected to the first connecting frame 23 and slidably sleeved on the first guide rod 21, and a motor assembled on the mounting plate 7 and with an output shaft connected to the end of the threaded rod 22.

[0048] In the above technical solution, when the motor is started to drive the threaded rod 22 to rotate, the first sliding sleeve 25 can be driven to slide on the first guide rod 21, so as to drive the pressing plate 11 to move closer to or away from the limiting plate 10 through the first connecting frame 23.

[0049] In a preferred embodiment of the invention, the pressing unit further includes a second guide rod 26 arranged parallel to the first guide rod 21 and with both ends fixedly connected to the corresponding mounting seats respectively, a blanking plate 27 located between the limiting plate 10 and the pressing plate 11, a second connecting frame 28 fixedly connected to the blanking plate 27, a second sliding sleeve 29 slidably sleeved on the first guide rod 21 and the second guide rod 21 and fixedly connected to the second connecting frame 28, a limiting member 30 fixedly sleeved on the first guide rod 21 and located on the side of the second sliding sleeve 29 away from the limiting plate 10, and a limiting rod 31 slidably passing through the first sliding sleeve 25 and the second sliding sleeve 29;

[0050] Both ends of the limiting rod 31 are fixedly assembled with limiting parts, the limiting member 30 is arranged away from the limiting plate 10, and the blanking plate 27 is provided with a plurality of second avoidance holes 32 corresponding to the conical parts 12 one by one.

[0051] In the above technical solution, when the extrusion plate 11 moves closer to the limiting plate 10, due to the provision of the blanking plate 27, the liquid extrusion plate will push the blanking plate 27 to move closer to the limiting plate 10 together, and the second sliding sleeve 29 slides on the first guiding rod 21 and the second guiding rod 26; after the liquid in the bag is discharged, the extrusion plate 11 moves away from the limiting plate 10. At this time, the conical member 12 pierces into the bag, so there will be a problem that the waste bag after liquid discharge cannot fall off from the conical member 12. When the extrusion plate 11 moves away from the limiting plate 10, after the second sliding sleeve 29 contacts the limiting member 30, the distance between the extrusion plate 11 and the blanking plate 27 increases as the extrusion plate 11 continues to move, and the conical member 12 moves away from the second avoidance hole 32, so that the waste bag on the conical member 12 can be removed.

[0052] The function of the limiting rod 31 is to limit the maximum distance between the blanking plate 27 and the extrusion plate 11, avoiding the problem that the waste bag cannot bring the blanking plate 27 back to its original position after falling off after the liquid extrusion is completed.

[0053] In a preferred embodiment of the invention, a return spring 33 is sleeved on the first guiding rod 21, and both ends of the return spring 33 are respectively in contact with the first sliding sleeve 25 and the second sliding sleeve 29.

[0054] In the above technical solution, the return spring 33 can assist the waste bag to fall off from the conical member 12.

[0055] In a preferred embodiment of the invention, the liquid receiving mechanism includes a liquid receiving box 34 with a port formed at the top, a liquid collecting member 35 whose top is fixedly connected to the lower surface of the mounting plate 7 and is sleeved outside a plurality of liquid discharge through grooves 19, a connecting pipe 36 whose end is threadedly assembled on the port, and a solenoid valve 37 whose two ends are respectively connected to the lower end of the liquid collecting member 35 and the end of the connecting pipe 36 away from the port.

[0056] In the above technical solution, during the liquid extrusion process, the solenoid valve 37 is opened, and the liquid will enter the liquid collecting member 35 through the liquid discharge through grooves 19, and flow into the liquid receiving box 34 through the solenoid valve 37 and the connecting pipe 36. After the liquid extrusion is completed, the solenoid valve 37 is closed, which can avoid the continuous volatilization of the liquid in the liquid receiving box 34.

[0057] In a preferred embodiment of the invention, the cover plate mechanism includes a first flat tube 38 fixedly connected to fit the edge of the first window 3, a second flat tube 39 fixedly connected to fit the edge of the second window 4, a horizontal first cover plate 40 sliding through the side wall of the first flat tube 38, a horizontal second cover plate 41 sliding through the side plate of the second flat tube 39 along the sliding direction of the first cover plate 40, a third connecting frame 42 fixedly connected to the first cover plate 40 and the second cover plate 41, and a driving push rod 43 assembled on the lower surface of the top plate 5 and whose moving end is fixedly connected to the third connecting frame 42.

[0058] In the above technical solution, the driving push rod 43 drives the third connecting frame 42 to move away from the first flat tube 38 and the second flat tube 39, the first cover plate 40 and the second cover plate 41 slide, and the first window 3 and the second window 4 are opened; when the third connecting frame 42 slides close to the first flat tube 38 and the second flat tube 39, the first window 3 and the second window 4 are thus closed.

[0059] In a preferred embodiment of the invention, a vertical material guiding tube 44 is fixedly connected to the lower end of the second flat tube 39.

[0060] In the above technical solution, after the waste bag is put into the second window 4, it will fall into the waste bag bucket 9 along the material guiding tube 44 for collection.

[0061] In a preferred embodiment of the invention, a splash-proof plate 45 is fixedly assembled at the top of the side of the limiting plate 10 away from the pressing plate 11, and a splash-proof shell 46 sleeving outside a plurality of conical members 12 is assembled on the side of the pressing plate 11 away from the limiting plate 10, and the top and both side edges of the splash-proof shell 46 are fixedly connected to the pressing plate 11.

[0062] In the above technical solution, both the splash-proof shell 46 and the splash-proof plate 45 play a role in preventing splashing, preventing liquid from splashing out of the splash-proof box 18.

However, the present invention is not limited to the specific details in the above embodiments.
