Description

Technical Field

[0001] The utility model relates to a peritoneal dialysis waste liquid treatment device. Background Art

[0002] Peritoneal dialysis uses the semi-permeable membrane properties of the patient's own peritoneum to regularly and regularly infuse dialysate into the abdominal cavity, and then discharge the waste liquid from the body. It can remove metabolic products retained in the body, correct electrolyte and acid-base imbalances, and ultrafilter excess water. The waste liquid discharged from the body needs to be specially treated. The steps of waste liquid treatment are generally divided into six steps: collecting peritoneal dialysis waste liquid generated by patients; using special containers for safe storage; transporting through medical waste treatment centers; using high-temperature sterilization or chemical disinfection to eliminate pathogenic microorganisms; further wastewater treatment, such as precipitation, filtration, neutralization, oxidation and other processes to remove harmful substances; after meeting the standards, discharge into the sewage treatment system or dispose of according to the prescribed procedures; follow the medical waste management regulations throughout the process to ensure environmental and public safety.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0029] See also Figure 1 to Figure 6 In an embodiment of the utility model, a peritoneal dialysis waste liquid treatment device comprises a workbench 1 and a support frame 2 mounted on the workbench 1, a plunger tank 4 is mounted on the support frame 2, an extrusion assembly is arranged inside the plunger tank 4, and the extrusion assembly is connected to the injection assembly mounted at the bottom of the plunger tank 4;

[0030] Also includes a filter tank 3 disposed at the bottom of the plunger tank 4 and rotatably connected to the workbench 1, wherein the filter tank 3 is detachably mounted with a funnel-shaped filter element 5, wherein the filter element 5 is made of a cellulose membrane and a synthetic polymer membrane;

[0031] The driving rotating member is arranged on the workbench 1 and connected to the filter tank 3. Every time the filter tank 3 rotates one circle, the spraying position of the spraying assembly on the filter element 5 is controlled to change.

[0032] In detail, in this embodiment, the peritoneal dialysis waste liquid treatment device described in the utility model is adopted. When in use, all waste liquids are collected uniformly after the peritoneal dialysis is completed. First, the waste liquid must be pretreated to remove large solid particles, suspended matter and other impurities in the liquid. The extrusion component is controlled to perform drainage work on the plunger tank 4, and the waste liquid in the plunger tank 4 is sprayed toward the filter tank 3 through the injection component. At the same time, the driving rotating part is started to control the rotation of the filter tank 3, so that the injection position of the injection component to the filter element 5 continues to change, and each time the filter tank 3 rotates one circle, the injection angle of the injection component is driven to change, so that when the filter element 5 filters the waste liquid, the utilization area of ​​the filter element 5 is increased, and the impurities on the waste liquid can be prevented from being deposited in large quantities at the same position on the filter element 5.

[0033] It should be noted that the spray line of the spray assembly on the filter element 5 is spiral-like, and the filter element 5 is arranged in a funnel shape in order to prevent the waste liquid from splashing out of the filter tank 3 during spraying.

[0034] Preferably, a water inlet hole and a water outlet hole are formed on the plunger tank 4, and a one-way valve is respectively arranged on the water inlet hole and the water outlet hole. When the extrusion assembly moves upward relative to the plunger tank 4, the plunger tank 4 performs water pumping work. At this time, the one-way valve on the water inlet hole opens, and the waste liquid from the outside enters the plunger tank 4. When the extrusion assembly moves downward, the plunger tank 4 performs water drainage work. At this time, the one-way valve on the water outlet hole opens, and the waste liquid in the plunger tank 4 enters the injection assembly through the water outlet hole.

[0035] See also Figure 4 and Figure 6 The extrusion assembly includes a piston 6 that is sealingly and slidably arranged in the plunger tank 4, and a movable shaft 7 is arranged along the axial direction of the piston 6. The movable shaft 7 passes through one end of the plunger tank 4 and is connected to the driving movable member.

[0036] The driving moving member includes a driving shaft 26 rotatably mounted on the support frame 2, the driving shaft 26 is driven to rotate by a first motor 17 mounted on the support frame 2, one end of the driving shaft 26 away from the first motor 17 is connected to a driving wheel 16, and an eccentric shaft 1601 is provided at an eccentric position of the driving wheel 16;

[0037] It also includes a movable plate 15, which is slidably set on the support frame 2 through a guide rod 1502. A limiting groove 1501 that slides with the eccentric shaft 1601 is formed on one end of the movable plate 15 facing the driving wheel 16, and the other end of the movable plate 15 is connected to the movable shaft 7.

[0038] When the first motor 17 is started, the output shaft on the first motor 17 rotates. When the output shaft rotates, it drives the drive shaft 26 to rotate synchronously. When the drive shaft 26 rotates, it drives the drive wheel 16 to rotate accordingly, so that the eccentric shaft 1601 makes a circular motion with the drive shaft 26 as the center. When the eccentric shaft 1601 revolves, it squeezes the movable plate 15. Under the action of the guide rod 1502, the eccentric shaft 1601 rotates one circle and the movable plate 15 reciprocates once. When the movable plate 15 moves, it drives the movable shaft 7 to move synchronously, so that the piston 6 moves up and down relative to the plunger tank 4, so as to realize the driving requirements of pumping and draining water in the plunger tank 4.

[0039] Preferably, the piston 6 is made of rubber material to ensure the sealing between the edge of the piston 6 and the inner wall of the plunger tank 4.

[0040] See also Figure 5 The injection assembly includes an injection pipe 14, one end of which is connected to the plunger tank 4 and communicated with the inside, and the other end is provided with a connecting ring 13, and the connecting ring 13 is provided with a locking structure connected to the locking plate 8 installed at the bottom of the plunger tank 4.

[0041] It should be noted that the injection pipe 14 is divided into three parts, a first hard pipe, a second soft pipe and a third hard pipe. The first hard pipe is connected to the water outlet at the bottom of the plunger tank 4, the second soft pipe is arranged between the first hard pipe and the third hard pipe, and an injection head is arranged on the end of the third hard pipe away from the second soft pipe, so that when the third hard pipe is deflected, the first hard pipe and the third hard pipe are always kept in a connected state under the action of the second soft pipe.

[0042] A slide groove 801 is formed on the locking plate 8 , and a plurality of equally spaced locking holes 8011 are arranged in the slide groove 801 .

[0043] The locking structure includes a connecting tube 12 and a connecting rod 10, one end of the connecting tube 12 is connected to the connecting ring 13, and the connecting rod 10 is slidably arranged in the other end, and the end of the connecting rod 10 away from the connecting tube 12 extends into the slide groove 801 and is slidably connected to the slide groove 801, and a pulley 9 that can be inserted into the lock hole 8011 is rotatably installed on the connecting rod 10;

[0044] The spring 11 is also included. The spring 11 is arranged inside the connecting tube 12 . One end of the spring 11 abuts against the connecting tube 12 , and the other end abuts against the inner bottom of the connecting rod 10 .

[0045] To elaborate, when the plunger tank 4 is draining, the waste liquid in the plunger tank 4 is sprayed toward the filter element 5 through the spray pipe 14 for filtration, and the filter tank 3 rotates one circle, driving the third hard tube to deflect, and the deflection angle of the third hard tube is the angle between two adjacent lock holes 8011. When the third hard tube is driven, the connecting ring 13 is driven to deflect synchronously, so that the pulley 9 follows the deflection. When the pulley 9 is deflected, it is subjected to the inclined squeezing force generated by the lock hole 8011, so that the pulley 9 moves toward one end of the connecting rod 10, driving the connecting rod 10 to slide toward the connecting tube 12, so that the spring 11 is compressed to reserve elastic potential energy. When the pulley 9 deflects to the next lock hole 8011, it is quickly inserted into the lock hole 8011 under the action of the spring 11, so as to achieve the locking of the position of the third hard tube and avoid the change of the injection direction under the action of gravity.

[0046] See also Figure 2 and Figure 3 The driving rotating member includes a cylindrical member 19 rotatably mounted on the workbench 1 , the cylindrical member 19 is driven to rotate by a second motor 18 mounted on the workbench 1 , and the cylindrical member 19 is rotationally connected to the filter tank 3 through a first gear set 20 .

[0047] The peritoneal dialysis waste liquid treatment device also includes a linkage structure connecting the filter tank 3 and the connecting ring 13, and the linkage structure includes a first transmission shaft 22 rotatably installed on the workbench 1, the first transmission shaft 22 is rotatably connected to the filter tank 3 through a second gear set 21, the first transmission shaft 22 is rotatably connected to the second transmission shaft 24 rotatably installed at the bottom of the plunger tank 4 through a bevel gear set 23, and a cam 25 is connected to the end of the second transmission shaft 24 away from the first transmission shaft 22, and the cam 25 is connected to the connecting ring 13 at an eccentric position.

[0048] Further, when the drainage work is performed in the above-mentioned plunger tank 4, the second motor 18 is started, and the working output shaft of the second motor 18 rotates. When the output shaft rotates, it drives the cylindrical member 19 to rotate synchronously. When the cylindrical member 19 rotates, the filter tank 3 is rotated under the action of the first gear set 20. At this time, the injection direction of the third hard tube is fixed, but the position of the injection on the filter element 5 changes with the rotation of the filter element 5. When the filter tank 3 rotates to one circle, under the action of the second gear set 21, the first transmission shaft 22 is rotated. When the first transmission shaft 22 rotates, under the action of the bevel gear set 23, the second transmission shaft 24 is driven to rotate. When the second transmission shaft 24 rotates, it drives the cam 25 to swing. Under the action of the cam 25, the injection angle of the third hard tube is changed.

[0049] It should be noted that a water collecting tank is formed in the filter tank 3 , and the filtered waste liquid enters the water collecting tank and is discharged to the outside through the water outlet 301 arranged at the bottom of the filter tank 3 .

[0050] In general, when the plunger tank 4 finishes the drainage work, the injection pipe 14 is now located at the end of the deflection stroke. When the plunger tank 4 performs the pumping work again, the injection angle of the injection pipe 14 is reset to prepare for the next injection.
