Description

Technical Field

[0001] This utility model belongs to the field of hemodialysis technology, and in particular relates to a hemodialysis device with a flow-controllable hollow fiber ultrafiltration membrane. Background Technology

[0002] Existing hemodialysis machines typically have fixed blood inlet and outlet diameters, such as the commonly used 38.5mm and 42.5mm sizes. During use, the blood flow rate cannot be controlled, limiting the applicable range of the hemodialysis machine. Furthermore, changing the blood flow rate usually requires replacing the entire hemodialysis machine, which is complex and can easily lead to waste. Therefore, a hemodialysis machine with a flow-controllable hollow fiber ultrafiltration membrane is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a hemodialysis machine with a controllable flow rate using a hollow fiber ultrafiltration membrane. By setting an adjustment component, specifically, the operator rotates the second cover, causing the second fan blade to rotate as well. When the second fan blade rotates, it overlaps with the first fan blade, thereby controlling the flow rate of blood into the hemodialysis machine body. This avoids the need to replace the hemodialysis machine due to its fixed flow rate. It also solves the problem that existing hemodialysis machines typically have fixed blood inlet and outlet diameters (tube diameters), such as the commonly used 38.5mm and 42.5mm sizes. In these cases, the blood flow rate cannot be controlled, limiting the applicability of the hemodialysis machine. Furthermore, changing the blood flow rate usually requires replacing the corresponding hemodialysis machine, which is complex and can easily lead to waste.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a hemodialysis machine with a flow-controllable hollow fiber ultrafiltration membrane, comprising a main frame mechanism, the main frame mechanism including a hemodialysis machine body, an adjustment component disposed on the left side of the hemodialysis machine body, a sealing component disposed inside the adjustment component, the adjustment component including a second cover, a second fan blade fixedly connected to the left side inside the second cover, the number of second fan blades being several, the several second fan blades being arranged in a circumferential array, a protruding edge disposed on the right side of the several second fan blades, a first fan blade fixedly connected to the left side inside the protruding edge.

[0006] Furthermore, the number of fan blades is several, and the several fan blades are arranged in a circular array. The right side of the inner wall of the convex edge is fixedly connected to the outer surface of the hemodialyzer body. The right side of the inner wall of the cover is fixedly connected to several protrusions, and the several protrusions are arranged in a circular array.

[0007] Furthermore, the sealing assembly includes a cover body three, the interior of which is threadedly connected to the outer surface of the protruding edge, and the left side of the outer surface of the cover body three is slidably connected to the interior of the cover body two.

[0008] Furthermore, a number of protrusions 2 are fixedly connected to the top of the cover body 3. The number of protrusions 2 are arranged in a circumferential array, and the outer surface of the number of protrusions 2 is in contact with the outer surface of protrusion 1.

[0009] Furthermore, a limiting plate is provided on the right side of the cover body, the top of the limiting plate is fixedly connected to the outer surface of the convex edge, the limiting plate is L-shaped, and a pushing block is provided on the left side of the limiting plate.

[0010] Furthermore, a spring is fixedly connected to the top of the inside of the push block. There are several springs arranged in a circular array.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting an adjustment component, specifically, allows the operator to rotate the cover two, causing the fan blade two to rotate as well. When the fan blade two rotates, it will overlap with the fan blade one, thereby controlling the flow rate of blood into the hemodialysis machine body. This avoids the need to replace the hemodialysis machine due to its non-adjustable flow rate, greatly improving the applicability of the hemodialysis machine, while also significantly reducing the number of times the operator needs to replace the hemodialysis machine, greatly reducing the workload of the operator, and significantly reducing the cost of using the hemodialysis machine.

[0014] 2. This utility model, by setting a sealing component, specifically, requires the operator to rotate the cover three clockwise to contact the pushing block. At the same time, the spring, limited by the convex edge, generates a certain rebound force and exerts force on the cover three, making it more secure and preventing it from falling off and preventing blood from spilling out. When the cover three moves, its interior will compress the rubber ring. The rubber ring, limited by the support plate, will expand to achieve a sealing effect, preventing blood from spilling out. This greatly improves the cleanliness of the medical environment and also significantly reduces environmental pollution.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5As shown, this utility model is a hemodialysis machine with a controllable flow rate hollow fiber ultrafiltration membrane, including a main frame mechanism 1. The main frame mechanism 1 includes a hemodialysis machine body 111. An adjustment component 2 is arranged on the left side of the hemodialysis machine body 111. A sealing component 3 is arranged inside the adjustment component 2. The adjustment component 2 includes a cover 214. A fan blade 212 is fixedly connected to the left side of the cover 214. There are several fan blades 212 arranged in a circular array. A protruding edge 215 is arranged on the right side of the fan blades 212. A fan blade 211 is fixedly connected to the left side of the protruding edge 215. Specifically, when the operator rotates the cover 214, the fan blades 212 rotate together. When the fan blades 212 rotate, they will overlap with the fan blades 211. This system controls the flow rate of blood into the dialyzer body 111, avoiding the need for replacement due to the dialyzer's flow rate being unadjustable. This significantly expands the dialyzer's applicability, reduces the frequency of dialyzer replacements, decreases workload, and lowers operating costs. The dialyzer has several blades 211 arranged in a circular array. The right side of the inner wall of the protruding edge 215 is fixedly connected to the outer surface of the dialyzer body 111. Several protrusions 213 are fixedly connected to the right side of the inner wall of the cover 214, also arranged in a circular array. As the cover 214 rotates, it drives the protrusions 213 and 214 in a circular array. 3. Contact is made, greatly increasing friction. The sealing component 3 includes a cover 312. The inside of the cover 312 is threadedly connected to the outer surface of the protruding edge 215. The left side of the outer surface of the cover 312 is slidably connected to the inside of the cover 214. Specifically, when the operator rotates the cover 312 clockwise, it contacts the pushing block 314. At the same time, the spring 315, limited by the protruding edge 215, generates a certain rebound force and exerts force on the cover 312, making it more secure and preventing it from falling off and preventing blood leakage. When the cover 312 moves, its interior will compress the rubber ring 317. The rubber ring 317, limited by the support plate 316, will expand to achieve a sealing effect, preventing blood leakage and greatly improving the cleanliness of the medical environment. This design also significantly reduces environmental pollution. Several protrusions 313 are fixedly connected to the top of the cover 312. These protrusions 313 are arranged in a circular array, and their outer surfaces are in contact with the outer surface of protrusion 213. Simultaneously, as the cover 214 rotates, it causes protrusions 213 to contact each other, greatly increasing friction and providing a certain degree of limiting. A limiting plate 311 is located on the right side of the cover 312. The top of the limiting plate 311 is fixedly connected to the outer surface of the protruding edge 215. The limiting plate 311 is L-shaped. A pushing block 314 is located on the left side of the limiting plate 311. The limiting plate 311 also provides a certain degree of limiting for the cover 312. A spring 315 is fixedly connected to the top of the inside of the pushing block 314.Several springs 315 are arranged in a circular array. The side of each spring 315 furthest from the push block 314 is fixedly connected to the top of the protruding edge 215. A support plate 316 is fixedly connected to the left side of the outer surface of the protruding edge 215. A rubber ring 317 is fixedly connected to the left side of the support plate 316. The outer surface of the rubber ring 317 contacts the left side of the interior of the cover 312. When the cover 312 moves, its interior compresses the rubber ring 317. The rubber ring 317 expands under the limiting effect of the support plate 316, thus achieving a sealing function. A cover 112 is fixedly connected to the left side of the cover 214. An infusion tube 113 is fixedly connected to the side of the cover 112 furthest from the hemodialysis machine body 111. During use, the patient's blood infusion tube 113 flows into the cover 112 and then into the hemodialysis machine body 111.

[0026] One specific application of this embodiment is as follows: During use, the patient's blood infusion tube 113 flows into the cover 112, and then into the hemodialysis machine body 111. At this time, the operator rotates the cover 214, causing the fan blade 212 to rotate as well. While rotating, the inside of the cover 214 slides on the outer surface of the cover 312. When the fan blade 212 rotates, it overlaps with the fan blade 111, thereby controlling the flow rate of blood into the hemodialysis machine body 111. Simultaneously, the rotation of the cover 214 causes the protrusion 113 to contact the protrusion 313, significantly increasing friction and providing a certain limiting effect. This prevents the fan blade 212 from rotating due to the force of blood flow, avoiding the need for replacement due to the hemodialysis machine's flow rate being unadjustable. This significantly expands the applicability of the hemodialysis machine and also greatly reduces the need for operators to replace it. The reduced frequency of use significantly lowers the workload of staff and the operating costs of the hemodialysis machine. During installation, staff rotate the cover 312 clockwise to fix it to the protruding edge 215. As the cover 312 moves, it contacts the pushing block 314. The pushing block 314 compresses the spring 315 under the force, while the spring 315, limited by the protruding edge 215, generates a certain rebound force and exerts force on the cover 312, making it more secure and preventing it from falling off and causing blood leakage. At the same time, the limiting plate 311 limits the cover 312. When the cover 312 moves, its interior compresses the rubber ring 317. The rubber ring 317, limited by the support plate 316, expands to seal and prevent blood leakage, greatly improving the cleanliness of the medical environment and significantly reducing environmental pollution.
