Description

Technical Field

[0001] This invention belongs to the technical field of hemodialysis diagnostic and treatment equipment for kidney diseases, specifically a precision fluid control treatment device for hemodialysis. Background Technology

[0002] Hemodialysis is a mainstream renal replacement therapy in clinical practice. It involves drawing blood from the patient through extracorporeal circulation, using the dialyzer's semi-permeable membrane for diffusion and ultrafiltration to remove metabolic toxins and excess water from the blood, and then returning the purified blood to the patient. It is often used for the long-term treatment of patients with acute and chronic renal failure. The hemodialysis precision fluid control therapy equipment is a specialized device for realizing this treatment process. The whole machine uses the dialysis unit as the carrier, and the dialyzer is fixedly installed in the upper middle position of the front of the dialysis unit. It is the core component for completing the exchange of substances between blood and dialysate. The equipment is equipped with a waste fluid pipeline. One end of the waste fluid pipeline is connected to the waste fluid outlet of the dialyzer, and the other end extends downward and connects to the waste fluid collection tank at the bottom of the equipment. The waste dialysate generated by dialysis is collected and temporarily stored in the waste fluid collection tank.

[0003] In existing conventional dialysis equipment, the waste fluid collection tank and waste fluid pipeline are simply connected by a plug. Medical staff need to periodically disassemble the waste fluid collection tank to empty the internal waste fluid. During the process of disconnecting the pipeline and removing the waste fluid collection tank, a large amount of residual waste fluid will remain inside the waste fluid pipeline. After the ends of the pipeline are no longer sealed, the residual waste fluid in the pipeline is very likely to drip continuously along the pipeline port. When the waste fluid drips onto the equipment frame, the ground, and the medical staff's operating table, it will form medical waste fluid pollution. This not only easily breeds bacteria and produces irritating odors, but the waste fluid containing pathogens will also increase the risk of occupational exposure and cross-infection for medical staff, resulting in poor hygiene and safety in clinical operation. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a precise fluid control treatment device for hemodialysis, which effectively solves the problem that residual waste liquid in the waste liquid pipeline may drip and cause pollution when the waste liquid collection box is disassembled and the internal waste liquid is poured out.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision fluid control treatment device for hemodialysis, comprising a dialysis host, a dialyzer fixedly installed on the top of the dialysis host, a side box fixedly installed on the side of the dialysis host, a collection mechanism provided on the side box, a support mechanism provided on the collection mechanism, and a waste fluid outlet pipe fixedly connected to the outside of the dialyzer, the bottom end of the waste fluid outlet pipe extending into the side box. The collection mechanism includes a collection box located inside the side chamber, directly below the bottom of the waste liquid outlet pipe. An installation block is fixedly installed on the outside of the collection box, and a rotating shaft is fixedly connected to the outside of the installation block. The end of the rotating shaft away from the installation block is rotatably connected to the inner side wall of the side chamber. An installation port is provided on the side of the side chamber away from the dialysis unit, and a collection box passes through the installation port. A side plate is fixedly connected to the side of the collection box away from the dialysis unit, and an installation plate located on the outside of the side chamber is fixedly connected to the side plate away from the collection box. A conical block is fixedly connected to the bottom of the collection box.

[0006] Preferably, the side box has two L-shaped round rods symmetrically fixedly connected inside, the collection box is located between the two L-shaped round rods, and a sliding plate is movably connected between the two L-shaped round rods. The side of the sliding plate away from the dialysis unit is symmetrically fixedly connected to the inner side wall of the side box with two springs, and the two springs are respectively sleeved on the outside of the two L-shaped round rods.

[0007] Preferably, the middle part of the skateboard is provided with a positioning groove, and a positioning plate is fixedly connected to the side of the collection box near the skateboard, and the positioning plate is adapted to the positioning groove.

[0008] Preferably, the side box is provided with a lifting frame inside, which is movably sleeved on the outside of two L-shaped round rods. Two movable rods are symmetrically rotatably connected to the outside of the lifting frame, and the bottom ends of the two movable rods are rotatably connected to the top of the slide plate.

[0009] Preferably, a bracket is fixedly connected to the inner side of the lifting frame, a toothed plate is fixedly installed on the outer side of the bracket, and a gear is fixedly installed on the outer side of the rotating shaft, with the gear meshing with the toothed plate.

[0010] Preferably, the mounting plate has a top groove at the top, an inner shaft is rotatably connected to the inner side of the top groove, a rotating plate is fixedly sleeved on the outer side of the inner shaft, the rotating plate is horizontally located in the top groove, and a limiting hole is provided on the rotating plate.

[0011] Preferably, an L-shaped block is fixedly connected to the outer side of the side box, and a limiting rod is fixedly connected to the inner side of the L-shaped block. The outer diameter of the limiting rod is equal to the inner diameter of the limiting hole.

[0012] Preferably, the support mechanism includes a support cylinder located outside the rotating shaft, a support plate fixedly connected between the outer side of the support cylinder and the inner top wall of the side box, and a tapered cylinder fixedly installed on the outer side of the rotating shaft, the tapered cylinder being located between the support cylinder and the mounting block.

[0013] Preferably, the inner side of the support cylinder is rotatably connected with multiple rollers at equal angles, and each roller abuts against the outer wall of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by pushing the collection box into the side box, can move the sliding plate, which facilitates the deformation of the two springs and allows the collection box to rotate so that its opening faces downward. This allows the waste liquid received in the collection box to be poured into the collection box, and also allows the waste liquid discharged from the waste liquid outlet pipe to enter the collection box for collection. When the collection box is removed from the side box, the collection box can rotate under the action of the two spring forces, so that the opening of the collection box faces upward to catch the residual waste liquid dripping from the waste liquid outlet pipe, effectively preventing the residual waste liquid in the waste liquid outlet pipe from dripping and causing pollution.

[0015] 2. This invention allows the sliding plate to move by pushing the collection box into the side box, which facilitates the deformation of the two springs. At this time, the rotating plate can be rotated to allow the two springs to reset, so that the rotating plate passes through the limiting hole and fits on the outside of the limiting rod until it abuts against the L-shaped block, thereby facilitating the quick installation of the collection box into the side box.

[0016] 3. This invention can support the rotating shaft through the cooperation between the support cylinder, the support plate, and the rollers, thereby facilitating the stability of the liquid collection box during rotation. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1, by Figures 1-8 The present invention relates to a precision fluid control treatment device for hemodialysis, comprising a dialysis host 1, a dialyzer 6 fixedly mounted on the top of the dialysis host 1, a side box 4 fixedly mounted on the side of the dialysis host 1, a collection mechanism 2 provided on the side box 4, a support mechanism 3 provided on the collection mechanism 2, and a waste fluid outlet pipe 5 fixedly connected to the outside of the dialyzer 6, the bottom end of the waste fluid outlet pipe 5 extending into the side box 4. The equipment is equipped with a complete circulation pipeline, which includes a blood circulation branch, a dialysate delivery branch, and a waste liquid outlet pipe. Each branch is equipped with a distributed liquid monitoring component consisting of flow and pressure sensors to collect inflow and outflow data throughout the pipeline. Each branch also has a flow regulation mechanism consisting of an electric regulating valve and a regulating pump connected in series. The equipment's parameter control module integrates a control motherboard and a human-machine interface unit, corresponding to the various electrical structures and electrically connected to the liquid monitoring components and flow regulation mechanism. During operation, medical personnel pre-enter parameters through the parameter control module. The system monitors the patient's physical indicators and dialysis treatment parameters. During treatment, the fluid monitoring component collects fluid operation data from each circulation pipeline in real time and feeds it back to the parameter control module. The parameter control module uses a built-in program to compare and analyze the data, and then outputs control commands to the flow regulation mechanism to adjust the infusion and drainage rates of each pipeline in real time, forming a complete closed-loop control system. This system dynamically adapts to the dialysis treatment needs of different patients, accurately controls the total amount of dialysis fluid replacement, and stably maintains the patient's fluid balance throughout the dialysis process. It effectively avoids various diagnostic and treatment risks caused by fluid imbalance, and significantly improves the accuracy and safety of hemodialysis treatment.

[0022] In Example 2, based on Example 1, the collection mechanism 2 includes a collection box 201 located inside the side box 4. The collection box 201 is located directly below the bottom end of the waste liquid outlet pipe 5. An installation block 2014 is fixedly installed on the outer side of the collection box 201. A rotating shaft 2012 is fixedly connected to the outer side of the installation block 2014. The end of the rotating shaft 2012 away from the installation block 2014 is rotatably connected to the inner wall of the side box 4. An installation port is provided on the side of the side box 4 away from the dialysis unit 1. A collection box 202 passes through the installation port. The collection box 202 is away from the dialysis unit 1. A side plate 203 is fixedly connected to one side of the side box 201. A mounting plate 204 located outside the side box 4 is fixedly connected to the side of the side plate 203 away from the collection box 202. A conical block 2013 is fixedly connected to the bottom of the collection box 201. The conical block 2013 is used to guide the flow of waste liquid. When the collection box 201 rotates until its opening faces downwards, the conical block 2013 is located at the top of the collection box 201. The waste liquid discharged from the waste liquid outlet pipe 5 flows completely into the collection box 202 through the guiding effect of the conical block 2013. Two... Two L-shaped cylindrical rods 2010 are connected together. A collection box 202 is located between the two L-shaped cylindrical rods 2010. A sliding plate 208 is movably connected between the two L-shaped cylindrical rods 2010. Two springs 205 are symmetrically fixed between the side of the sliding plate 208 away from the dialysis unit 1 and the inner wall of the side box 4. The two springs 205 are respectively sleeved on the outer side of the two L-shaped cylindrical rods 2010. A positioning groove 207 is provided in the middle of the sliding plate 208. A positioning plate 206 is fixedly connected to the side of the collection box 202 near the sliding plate 208. The positioning plate 206 is aligned with the positioning groove 207. The side box 4 is equipped with a lifting frame 2011 inside. The lifting frame 2011 is movably sleeved on the outside of two L-shaped round rods 2010. Two movable rods 209 are symmetrically rotatably connected to the outside of the lifting frame 2011. The bottom ends of the two movable rods 209 are rotatably connected to the top of the slide plate 208. A bracket 2017 is fixedly connected to the inside of the lifting frame 2011. A toothed plate 2016 is fixedly installed on the outside of the bracket 2017. A gear 2015 is fixedly installed on the outside of the rotating shaft 2012. The gear 2015 meshes with the toothed plate 2016. First, push the collection box 202 into the side box 4 from the installation port, so that the positioning plate 206 is inserted into the positioning groove 207. When the collection box 202 comes into contact with the sliding plate 208, push the collection box 202 again, causing the sliding plate 208 to slide along the two L-shaped round rods 2010. At this time, both springs 205 are stretched. Then, through the two movable rods 209, the lifting frame 2011 slides upward along the two L-shaped round rods 2010, and drives the bracket 2017 and the toothed plate 2016 to rise. Since the toothed plate 2016 meshes with the gear 2015, the rotating shaft 2012 rotates, and drives the liquid collection box 201 to rotate until the opening of the liquid collection box 201 faces downward. At the same time, the collection box 202 is located below the liquid collection box 201. At this time, the waste liquid received in the liquid collection box 201 flows into the collection box 202 under the action of gravity, and the waste liquid discharged from the waste liquid outlet pipe 5 also enters the collection box 202 for collection. When the collection box 202 is pulled out from the side box 4, the two springs 205 reset and drive the slide plate 208 to slide horizontally along the two L-shaped round rods 2010, causing the lifting frame 2011 to descend. At the same time, the rotating shaft 2012 and the liquid collection box 201 rotate until the opening of the liquid collection box 201 faces upward. Finally, the residual waste liquid in the waste liquid outlet pipe 5 drips into the liquid collection box 201 for collection to avoid pollution.

[0023] In Example 3, based on Example 1, the top of the mounting plate 204 is provided with a top groove 2019, the inner side of the top groove 2019 is rotatably connected to an inner shaft 2021, the outer side of the inner shaft 2021 is fixedly sleeved with a rotating plate 2020, the rotating plate 2020 is horizontally located in the top groove 2019, the rotating plate 2020 is provided with a limiting hole 2018, the outer side of the side box 4 is fixedly connected to an L-shaped block 8, the inner side of the L-shaped block 8 is fixedly connected to a limiting rod 7, and the outer diameter of the limiting rod 7 is equal to the inner diameter of the limiting hole 2018; First, push the collection box 202 into the side box 4, causing the sliding plate 208 to slide along the two L-shaped rods 2010. At this time, both springs 205 deform and cause the liquid collection box 201 to rotate until the mounting plate 204 abuts against the outer wall of the side box 4. Then, rotate the rotating plate 2020 to a position perpendicular to the mounting plate 204. At this time, the rotating plate 2020 abuts against the inner long side of the L-shaped block 8. Then, under the elastic force of the two springs 205, the rotating plate 2020 passes through the limiting hole 2018 and fits onto the outside of the limiting rod 7 until the rotating plate 2020 abuts against the inner short side of the L-shaped block 8. At this time, the opening of the liquid collection box 201 faces downward, and the collection box 202 is located directly below the liquid collection box 201. Finally, the quick installation of the collection box 202 is completed.

[0024] In Example 4, based on Example 1, the support mechanism 3 includes a support cylinder 301 located outside the rotating shaft 2012. A support plate 303 is fixedly connected between the outer side of the support cylinder 301 and the inner top wall of the side box 4. A conical cylinder 302 is fixedly installed on the outer side of the rotating shaft 2012. The conical cylinder 302 is located between the support cylinder 301 and the mounting block 2014. Multiple rollers 304 are rotatably connected at equal angles on the inner side of the support cylinder 301. Each roller 304 abuts against the outer wall of the rotating shaft 2012. The conical cylinder 302 is used to guide the flow of waste liquid. When the collection box 201 rotates so that its opening faces downward, it prevents the waste liquid from flowing along the rotating shaft 2012, allowing the liquid to flow completely into the collection box 202. By setting multiple rollers 304 inside the support cylinder 301, the support and limit of the rotating shaft 2012 are achieved, and the support cylinder 301 does not directly contact the rotating shaft 2012, so as not to affect the normal rotation of the rotating shaft 2012, thereby ensuring the stability of the liquid collection box 201 during rotation.
