Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a cleaning device for a blood perfusion adsorbent. Background Art

[0002] Hemoperfusion (HP) is a blood purification treatment method that draws the patient's blood from the body into the extracorporeal circulation system, and uses the adsorbents in the perfusion device (such as resins, activated carbon and other materials) to adsorb and combine with the metabolites, toxic substances and drugs to be removed from the body to achieve the purpose of removing these substances. Hemoperfusion adsorbents are the core materials in hemoperfusion technology and are mainly used to remove harmful substances in the blood. Before using hemoperfusion adsorbents, they need to be pretreated to extract organic solvents in the hemoperfusion adsorbents and remove particulate contaminants to ensure that they can effectively purify the blood.

[0003] A Chinese patent application document with publication number CN117680419A discloses a medical resin cleaning device and a cleaning method. The medical resin cleaning device is configured by spacing the inner wall of a cleaning tank and the outer wall of a foreign matter dispersion filter to form a spacing space, and then arranging a partition component in the spacing space to divide the spacing space into two mutually unconnected first areas and second areas through the partition component, and then arranging a flushing liquid inlet on the cleaning tank located at the first area, injecting flushing liquid through the flushing liquid inlet, and arranging a flushing liquid outlet on the cleaning tank located at the second area. Impurities on the resin can be discharged along the flushing liquid outlet with the flushing liquid after being cleaned and precipitated by the foreign matter dispersion filter, and in particular, micro foreign matters in the resin that are invisible to the human eye can also be discharged along the flushing liquid in a specified direction (from the flushing liquid inlet to the flushing liquid outlet), thereby improving the cleaning effect of the resin, improving the resin cleaning efficiency, and reducing the cleaning cost.

[0004] However, during the cleaning process, the above-mentioned medical resin cleaning device and cleaning method in the prior art only use a flushing liquid to flush the resin, which makes it difficult to separate the particulate contaminants with strong adhesion from the resin, and the flushed particulate contaminants may attach to the resin again in the diffusion filter, resulting in incomplete cleaning. Summary of the invention

[0005] The present invention provides a cleaning device for a blood perfusion adsorbent, aiming to solve the problem that it is difficult to separate the highly adhesive particulate pollutants from the resin in the related art medical resin cleaning devices and cleaning methods, and the particulate pollutants washed off may adhere to the resin again in the diffusion filter, thereby resulting in incomplete cleaning.

[0006] The present invention provides a cleaning device for a blood perfusion adsorbent using the following technical solution: A cleaning device for blood perfusion adsorbent, comprising a holding tank, a cleaning chamber formed in the holding tank, and two cross-arranged partition plates installed in the cleaning chamber and rotatable around the central axis of the holding tank, a scrubbing plate mounted on the partition plates and moving up and down, a rotary drive mechanism arranged at the bottom of the holding tank, a distributor arranged below the cleaning chamber, and a flushing pipe connected to the distributor; the two partition plates divide the cleaning chamber into four fan-shaped areas for cleaning adsorbent, the rotary drive mechanism is used to drive the two partition plates to rotate around the central axis of the holding tank so that the volume of one of the two adjacent fan-shaped areas increases and the volume of the other decreases, the partition plate has a water hole for allowing liquid to pass through, the scrubbing plate is used to scrub the adsorbent in the fan-shaped area; the distributor has a water injection hole connected to the bottom end of the cleaning chamber, the flushing pipe is used to transport cleaning liquid to the distributor, so that the cleaning liquid is injected into the cleaning chamber through the water injection hole, and an overflow port is formed on the top outer edge of the holding tank, which is used to allow the cleaning liquid to drive the particulate pollutants to be discharged from the overflow port.

[0007] By adopting the above technical scheme, four fan-shaped areas with adjustable volumes are formed in the holding tank by setting two partition plates, and the distribution density of the resin in each fan-shaped area can be controlled, the cleaning flexibility is improved, and different cleaning strengths and cleaning effects can be achieved. When the volume of the fan-shaped area decreases, the distribution density of the resin in the fan-shaped area increases, the contact frequency and contact area between the resins increase, and the up and down scrubbing of the scrubbing plate increases the friction between the resin particles, thereby improving the cleaning intensity, helping to remove the particulate pollutants on the resin faster, and helping the particulate pollutants with strong adhesion to separate from the resin. When the volume of the fan-shaped area increases, the distribution density of the resin in the fan-shaped area decreases, the contact frequency and contact area between the resins decrease, and the up and down stirring of the scrubbing plate is coordinated, and the particulate pollutants washed can be better dispersed in the cleaning liquid, and then overflow from the overflow port as the cleaning liquid flows from the lower end to the upper end, avoiding the particulate pollutants washed to attach to the resin again. In this way, the resin can be cleaned more effectively, the cleaning quality is improved, and incomplete cleaning is avoided.

[0008] Furthermore, the cleaning device for the blood perfusion adsorbent also includes a supporting box for accommodating a containing tank, an opening and closing cover hinged on the supporting box, a discharge chamber is formed between the outer wall of the containing tank and the supporting box, a discharge pipe connected to the discharge chamber is provided on the supporting box, and one end of the discharge pipe away from the discharge chamber is connected to the outside world, the flushing pipe is provided on the supporting box and passes through the discharge chamber to be connected to the distributor, and one end of the flushing pipe away from the distributor is connected to the outside world.

[0009] Furthermore, the rotary drive mechanism includes a rotary motor, a first bevel gear, a first connecting member, a second bevel gear, a second connecting member, and an intermediate bevel gear. The output end of the rotary motor is connected to the first bevel gear, the intermediate bevel gear is meshed between the first bevel gear and the second bevel gear, the first connecting member is connected between the first bevel gear and one of the partition plates, and the second connecting member is connected between the second bevel gear and the other partition plate.

[0010] By adopting the above technical solution, the two opposite sector-shaped areas can be expanded or reduced from the angle bisector of the sector-shaped area to both sides at the same time. In this way, the volumes of the four sector-shaped areas are adjusted in pairs and evenly, which is convenient for operators to control and can ensure that the flow and distribution of the cleaning liquid in the cleaning chamber are more even, thereby achieving a balanced cleaning effect in each sector-shaped area.

[0011] Furthermore, the scrubbing boards are arranged in pairs, and the paired scrubbing boards are distributed on both sides of the partition board between two adjacent fan-shaped areas, and the paired scrubbing boards are divided into a first scrubbing board and a second scrubbing board.

[0012] By adopting the above technical solution, each scrubbing plate is mounted on the side of the plate body facing the fan-shaped area and moves up and down to scrub the resin in the fan-shaped area to increase the friction and stirring of the resin particles, which helps to more thoroughly remove the particulate contaminants on the resin.

[0013] Furthermore, the cleaning device of the blood perfusion adsorbent also includes a scrubbing drive mechanism for driving the scrubbing plate to move up and down, the scrubbing drive mechanism includes a scrubbing motor, a first rack, a first pressure ring, a second rack, a second pressure ring, and an intermediate gear, the output end of the scrubbing motor is connected to the intermediate gear, the intermediate gear is meshed between the first rack and the second rack, the first pressure ring is connected between the first rack and the first scrubbing plate, and the second pressure ring is connected between the second rack and the second scrubbing plate.

[0014] Furthermore, the scrubbing drive mechanism also includes an elastic member, which is connected between the partition plate and the scrubbing plate to apply an upward elastic force to the scrubbing plate to move the scrubbing plate up, the upper end of the first pressure ring is fixedly connected to the first rack, and the lower end of the first pressure ring is used to push the first scrubbing plate downward, the upper end of the second pressure ring is fixedly connected to the second rack, and the lower end of the second pressure ring is used to push the second scrubbing plate downward.

[0015] By adopting the above technical solution, the first rubbing plate and the second rubbing plate used to scrub the resin in each fan-shaped area can move up and down alternately, so that the resin can be subjected to uniform scrubbing force in multiple directions, and it is also beneficial to promote the flow of cleaning liquid, thereby improving the cleaning effect.

[0016] Furthermore, the cleaning device for the blood perfusion adsorbent also includes stirring members corresponding to each fan-shaped area and a stirring drive mechanism for driving the multiple stirring members to rotate, each of the stirring members includes a stirring shaft rotatably installed in the cleaning chamber, and multiple stirring blades fixed on the stirring shaft, the stirring drive mechanism includes a stirring motor, a stirring gear ring, and a stirring gear, each of the stirring shafts passes downward through the cleaning chamber and is equipped with a stirring gear, each of the stirring gears is meshed with the stirring gear ring, and the output end of the stirring motor is connected to any stirring gear.

[0017] By adopting the above technical scheme, the stirring element is used to stir the cleaning liquid in each fan-shaped area. When the volume of the fan-shaped area decreases, the resin and the cleaning liquid can be mixed evenly, which is beneficial to improve the cleaning intensity. When the volume of the fan-shaped area increases, the particulate pollutants flushed can be better dispersed in the cleaning liquid.

[0018] Furthermore, the cleaning device for the blood perfusion adsorbent also includes a support shaft fixed in the cleaning chamber, the support shaft extends along the central axis of the containing tank, each of the partition plates includes two plate bodies symmetrically distributed with the support shaft as the symmetry axis, and the two plate bodies are fixedly connected by a ring rotatably sleeved outside the support shaft.

[0020] The beneficial effect of the cleaning device of a blood perfusion adsorbent provided by the present invention is that four fan-shaped areas with adjustable volumes are formed in the holding tank by setting two partition plates, the distribution density of the resin in each fan-shaped area can be controlled, the cleaning flexibility is improved, and different cleaning strengths and cleaning effects can be achieved. When the volume of the fan-shaped area decreases, the distribution density of the resin in the fan-shaped area increases, the contact frequency and contact area between the resins increase, the up and down scrubbing of the scrubbing plate increases the friction between the resin particles, and the stirring of the stirring piece can make the resin and the cleaning liquid mix evenly, thereby improving the cleaning strength, helping to remove the particulate pollutants on the resin faster, and helping the particulate pollutants with strong adhesion to separate from the resin. When the volume of the fan-shaped area increases, the distribution density of the resin in the fan-shaped area decreases, the contact frequency and contact area between the resins decrease, and the particulate pollutants washed can be better dispersed in the cleaning liquid with the up and down stirring of the scrubbing plate and the stirring of the stirring piece. Then, as the cleaning liquid flows from the lower end to the upper end, it overflows from the overflow port, avoiding the particulate pollutants washed from being attached to the resin again. In this way, the resin can be cleaned more effectively, the cleaning quality is improved, and incomplete cleaning is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 7As shown, an embodiment of the cleaning device for blood perfusion adsorbent of the present invention comprises a support box 10, an opening and closing cover 110, a discharge pipe 130, a containing tank 20, a support shaft 220, a mounting cover 240, a partition plate 30, a rotary drive mechanism, a scrubbing plate 50, a scrubbing drive mechanism, a stirring member 70, a stirring drive mechanism, a distributor, and a flushing tube 920. The blood perfusion adsorbent in the embodiment is a resin.

[0031] like Figures 1 to 3 As shown, the support box 10 is in a rectangular parallelepiped shape, and the support box 10 has a receiving chamber with an opening facing upward, which is used to receive the receiving tank 20. A discharge chamber 120 is formed between the outer wall of the receiving tank 20 and the support box 10. Two flushing pipes 920 are arranged on the support box 10, and pass through the discharge chamber 120 to communicate with the bottom of the receiving tank 20. One end of the flushing pipe 920 away from the receiving tank 20 is connected to the outside, and the flushing pipe 920 is used to pass cleaning liquid into the receiving tank 20. Two discharge pipes 130 are arranged on the support box 10, and are connected to the discharge chamber 120. One end of the discharge pipe 130 away from the discharge chamber 120 is connected to the outside, and the discharge pipe 130 is used to discharge the cleaning liquid carrying particulate pollutants. The discharged cleaning liquid can be recycled after purification treatment to reduce the consumption and waste of the cleaning liquid. The opening and closing cover 110 is hinged on the supporting box 10 and can open or close the supporting box 10 . A circular cover plate 111 is fixed to the lower surface of the opening and closing cover 110 for covering the top of the containing tank 20 .

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the holding tank 20 can be detachably fixed in the holding chamber of the support box 10. A cylindrical cleaning chamber 210 is formed in the holding tank 20. An overflow port 230 is formed at the top outer edge of the holding tank 20, which is used to allow the cleaning liquid to drive the particulate pollutants to be discharged from the overflow port 230. After the opening and closing cover 110 is closed, an overflow space is left between the lower end outer edge of the cover plate 111 and the side wall of the holding tank 20, which is used to guide the cleaning liquid to overflow to the overflow port 230. Discharging particulate pollutants by overflow helps to maintain the cleanliness of the cleaning chamber 210, prevent the accumulation of pollutants, and reduce the possibility of pollutants being re-deposited on the resin surface during the cleaning process. The support shaft 220 is fixed in the cleaning chamber 210 and extends along the central axis of the holding tank 20. The mounting cover 240 is fixed at the bottom end of the holding tank 20, and a closed mounting space is formed in the mounting cover 240.

[0033] like Figure 2 and Figure 6As shown, the distributor is arranged below the cleaning chamber 210. The distributor includes a distribution plate 90 fixed in the holding tank 20 and located below the cleaning chamber 210, a water injection chamber 930 located between the lower surface of the distribution plate 90 and the inner wall of the holding tank 20, and a water injection hole 910 connected to the bottom end of the cleaning chamber 210 is opened on the distribution plate 90. The flushing pipe 920 is connected to the water injection chamber 930 and is used to transport the cleaning liquid to the distributor so that the cleaning liquid is injected into the cleaning chamber 210 through the water injection hole 910. The cleaning liquid flows from the lower end to the upper end, and can use gravity and flow power to more effectively wash particulate pollutants from the resin surface, improve the cleaning efficiency, and make every part of the resin layer be cleaned evenly to avoid cleaning dead corners.

[0034] like Figure 2 , Figure 4 and Figure 5 As shown, two partition plates 30 are cross-arranged and can be rotatably installed in the cleaning chamber 210 around the central axis of the holding tank 20. The two partition plates 30 divide the cleaning chamber 210 into four sector-shaped areas for cleaning resin. Each partition plate 30 includes two plate bodies 310 symmetrically distributed with the support shaft 220 as the symmetry axis. The two plate bodies 310 are fixedly connected by a ring 320 rotatably sleeved on the outside of the support shaft 220, and each plate body 310 has a water hole for allowing liquid to pass through.

[0035] like Figures 5 to 7 As shown, the rotary drive mechanism is disposed at the bottom of the holding tank 20, and is used to drive the two partition plates 30 to rotate around the central axis of the holding tank 20, so that the volume of one of the two adjacent sector-shaped areas increases and the volume of the other decreases, thereby controlling the distribution density of the resin in each sector-shaped area, improving the cleaning flexibility, and achieving different cleaning intensities and cleaning effects. The rotary drive mechanism includes a rotary motor 40, a first bevel gear 410, a first connecting member 411, a second bevel gear 420, a second connecting member 421, and an intermediate bevel gear 430.

[0036] The support shaft 220 penetrates downward into the installation space and is rotatably equipped with a first connecting member 411. The first connecting member 411 includes a first disk and a first sleeve that are fixedly connected. The lower end of the first sleeve is fixedly connected to the first bevel gear 410. The second connecting member 421 and the second bevel gear 420 are rotatably sleeved outside the first sleeve. The second connecting member 421 is in the shape of a disk, and the lower end of the second connecting member 421 is fixedly connected to the second bevel gear 420. The intermediate bevel gear 430 is rotatably installed in the installation space and meshes between the first bevel gear 410 and the second bevel gear 420. The first disk of the first connecting member 411 is fixedly connected to one of the collars 320, and the second connecting member 421 is fixedly connected to the other collar 320. The rotary motor 40 is installed at the bottom of the support box 10. The output end of the rotary motor 40 penetrates upward into the installation space and is connected to the first bevel gear 410 to drive the first bevel gear 410 to rotate.

[0037] Thus, when the rotary motor 40 drives the first bevel gear 410 to rotate, the first bevel gear 410 drives the second bevel gear 420 to rotate in the opposite direction to the rotation direction of the first bevel gear 410 through the intermediate bevel gear 430, and the first bevel gear 410 and the second bevel gear 420 drive the two collars 320 to rotate through the first connecting member 411 and the second connecting member 421 respectively, and the collars 320 of the two partition plates 30 rotate in opposite directions, so that the two opposite fan-shaped areas can be expanded or reduced to both sides from the angular bisector of the fan-shaped area at the same time. In this way, the volume of the four fan-shaped areas is adjusted in pairs and evenly, which is convenient for the operator to control, and can ensure that the flow and distribution of the cleaning liquid in the cleaning chamber 210 are more uniform, so as to achieve a balanced cleaning effect in each fan-shaped area.

[0038] like Figure 4 and Figure 5 As shown, the scrubbing plates 50 are arranged in pairs, and the paired scrubbing plates 50 are distributed on both sides of the plate body 310 between two adjacent fan-shaped areas, and the paired scrubbing plates 50 are divided into a first scrubbing plate and a second scrubbing plate. Each scrubbing plate 50 moves up and down and is assembled on the side of the plate body 310 facing the fan-shaped area, and is used to scrub the resin in the fan-shaped area to increase the friction and stirring of the resin particles, which helps to more thoroughly remove the particulate contaminants on the resin. The upper ends of the four first scrubbing plates are fixedly connected by the first scrubbing ring 510, and the upper ends of the four second scrubbing plates are fixedly connected by the second scrubbing ring 520. Each scrubbing plate 50 is water permeable and does not affect the flow of the cleaning liquid between the two adjacent fan-shaped areas.

[0039] like Figure 1 , Figure 3 and Figure 4As shown, the scrubbing driving mechanism is used to drive the scrubbing plate 50 to move up and down. The scrubbing driving mechanism comprises a scrubbing motor 60, a first rack 610, a first pressure ring 611, a second rack 620, a second pressure ring 621, an intermediate gear 630, and an elastic member 640. The scrubbing motor 60 is installed on the opening and closing cover 110, and the output end of the scrubbing motor 60 is connected to the intermediate gear 630, and the intermediate gear 630 is engaged between the first rack 610 and the second rack 620. The first pressure ring 611 is fixed to the lower end of the first rack 610, and is opposite to the first rubbing ring 510 up and down, and the second pressure ring 621 is fixed to the lower end of the second rack 620, and is opposite to the second rubbing ring 520 up and down. The elastic member 640 is connected between the partition plate 30 and the scrubbing plate 50, so that the scrubbing plate 50 is moved up by applying an upward elastic force to the scrubbing plate 50.

[0040] When the opening and closing cover 110 is opened, each elastic member 640 applies elastic force to the scrubbing plates 50 , so that each scrubbing plate 50 moves upward relative to the partition plate 30 , that is, the four first scrubbing plates and the four second scrubbing plates all move upward relative to the partition plate 30 . When the opening and closing cover 110 is closed, when the position of the first rack 610 is above the second rack 620, the lower end of the second pressure ring 621 pushes the second rubbing ring 520 to drive the four second rubbing plates to move downward. After starting the scrubbing motor 60, the intermediate gear 630 drives the first rack 610 to move downward, and the second rack 620 moves upward at the same time. The first rack 610 pushes the first rubbing ring 510 through the first pressure ring 611 to drive the four first rubbing plates to move downward. At this time, the pushing force of the second pressure ring 621 on the second rubbing ring 520 is released, and the four second rubbing plates can move upward under the action of the elastic member 640, and so on. The first rubbing plate and the second rubbing plate used to scrub the resin in each fan-shaped area can perform an up and down movement staggered with each other, so that the resin can be subjected to uniform scrubbing force in multiple directions, which is also beneficial to promote the flow of cleaning liquid, thereby improving the cleaning effect.

[0041] like Figure 2 and Figure 4 As shown, the stirring member 70 corresponds to each sector area and is used to stir the cleaning liquid in each sector area. Each stirring member 70 includes a stirring shaft 710 rotatably mounted in the cleaning chamber 210 and a plurality of stirring blades 720 fixed on the stirring shaft 710.

[0042] The stirring drive mechanism is arranged at the bottom of the holding tank 20, and is used to drive the plurality of stirring members 70 to rotate. The stirring drive mechanism includes a stirring motor 80, a stirring gear ring 810, and a stirring gear 820. Each stirring shaft 710 penetrates downward into the installation space and is equipped with a stirring gear 820, and each stirring gear 820 is meshed with the stirring gear ring 810. The stirring motor 80 is installed at the bottom of the support box 10, and the output end of the stirring motor 80 penetrates upward into the installation space and is connected to any stirring gear 820, thereby driving the stirring gear ring 810 to rotate, and then driving the remaining stirring gears 820 to rotate through the stirring gear ring 810.

[0043] It should be noted that Figures 2 to 4 As shown, when the volume of the fan-shaped area decreases, the distribution density of the resin in the fan-shaped area increases, the contact frequency and contact area between the resins increase, the scrubbing of the scrubbing plate 50 increases the friction between the resin particles, and the stirring of the stirring member 70 can make the resin and the cleaning liquid mix evenly, thereby improving the cleaning intensity, helping to remove the particulate pollutants on the resin more quickly, and helping the particulate pollutants with strong adhesion to separate from the resin. When the volume of the fan-shaped area increases, the distribution density of the resin in the fan-shaped area decreases, the contact frequency and contact area between the resins decrease, and with the up and down stirring of the scrubbing plate 50 and the stirring of the stirring member 70, the particulate pollutants washed can be better dispersed in the cleaning liquid, and then overflow from the overflow port 230 as the cleaning liquid flows from the lower end to the upper end, avoiding the particulate pollutants washed to adhere to the resin again. In this way, the resin can be cleaned more effectively, the cleaning quality can be improved, and incomplete cleaning can be avoided.
