Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a nephrology hemodialysis device. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution containing similar concentrations to the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection. This removes metabolic waste from the body, maintains electrolyte and acid-base balance, removes excess water from the body, and returns the purified blood. The entire process is called hemodialysis.

[0003] In the prior art, when a patient is dialyzing blood using a hemodialysis device, factors such as fat embolism, fibrin deposition, or platelet aggregation often cause blood to flow into the dialysis device's pipelines and cause pipeline blockage. The way to solve the pipeline blockage is usually to insert a special guide wire into the pipeline to clear the blocked pipeline. However, the above method usually requires the machine to be shut down for clearing, which reduces the patient's dialysis efficiency and increases the risk of infection for the patient, posing a major safety hazard to the patient's health.

[0045] The dialyzer body 11 is provided with a tank containing dialysate and a tank containing wastewater. A peristaltic pump is also provided at the end of the liquid inlet pipe 15 away from the dialyzer 12. The liquid inlet pipe 15 is fixedly connected to the tank containing dialysate, and the liquid outlet pipe 16 is fixedly connected to the tank containing wastewater.

[0046] Furthermore, in one implementation of the present invention, the processing mechanism 2 includes an expansion unit 21, which is located on the left side of the dialyzer body 11. The expansion unit 21 is used to expand the inner diameter of the blocked pipeline.

[0047] As a further limitation of the expansion unit 21 of the present invention, the expansion unit 21 includes a mounting frame 2101. The right side of the mounting frame 2101 is fixedly connected to the left side of the dialyzer body 11. A rotating motor 2102 is fixedly mounted on the back of the mounting frame 2101. An ultrasonic detector 2103 is fixedly mounted on the left side of the dialyzer body 11. A support plate 2104 is rotatably connected to the interior of the mounting frame 2101. The output end of the rotating motor 2102 is fixedly connected to the back of the support plate 2104.

[0048] The power provided by the rotating motor 2102 drives the support plate 2104 to adjust its angle, so that the blood inlet end of the blood inlet blood vessel 13 is in better contact with the patient, and the outer surface of the blood inlet blood vessel 13 is in contact with the upper surface of the support plate 2104;

[0049] Two connecting belts 2105 are fixedly installed on the upper surface of the support plate 2104, and two Velcros 2106 are fixedly installed on the front surface of the support plate 2104. The inner wall of each connecting belt 2105 is adhered to the front surface of the Velcro 2106, and the inner wall of the connecting belt 2105 is provided with a furry surface that meshes with the Velcro 2106, so that the connecting belt 2105 is passed around the blood inlet 13, thereby fixing the blood inlet 13. A rack plate 2107 is fixedly installed on the upper surface of the support plate 2104, and a placement rack 2108 is slidably connected to the upper surface of the support plate 2104. The internal rotation of the placement rack 2108 is connected to a connecting gear 2109, and the outer surface of the connecting gear 2109 is meshed with the upper surface of the rack plate 2107. Through the meshing action of the connecting gear 2109 and the rack plate 2107, the placement rack 2108 is driven to move on the rack plate 2107, thereby facilitating the detection of different positions of the blood inlet 13.

[0050] Preferably, a rotating motor 2110 is fixedly mounted on the back of the placement rack 2108 of the embodiment of the present disclosure, and the output end of the rotating motor 2110 is fixedly connected to the back of the connecting gear 2109. A connecting rack 2128 is fixedly mounted on the inner top wall of the placement rack 2108, and a probe 2111 and a discharge head 2112 are fixedly mounted on the inner wall of the connecting rack 2128. The ultrasonic detector 2103 is electrically connected to the probe 2111 via a wire, and the ultrasonic detector 2103 cooperates with the probe 2111 to emit ultrasonic waves into the interior of the blood inlet blood vessel 13, thereby using the ultrasonic waves to detect whether there is blockage inside the blood inlet blood vessel 13.

[0051] In addition, a material storage box 2113 and a delivery pump 2114 are fixedly installed on the upper surface of the placement rack 2108, the feeding end of the delivery pump 2114 passes through the interior of the material storage box 2113, the interior of the material storage box 2113 is provided with a coupling agent, the discharge end of the delivery pump 2114 is fixedly connected to a delivery pipe 2115, and the end of the delivery pipe 2115 away from the delivery pump 2114 passes through the interior of the discharge head 2112, and a connecting plate 2116 is fixedly installed on the inner wall of the placement rack 2108, a micro air pump 2117 is fixedly installed on the upper surface of the connecting plate 2116, and two electric push rods 2118 are fixedly installed on the bottom surface of the connecting plate 2116, and the telescopic ends of the two electric push rods 2118 are fixedly installed with a movable plate 2119. A mounting block 2120 is fixedly mounted on the side of the two movable plates 2119 that are close to each other. Two first suction cups 2121 are fixedly mounted on the inner walls of the two mounting blocks 2120. A connecting tube 2122 is fixedly mounted on the outer surface of each set of first suction cups 2121. The air inlet end of the micro air pump 2117 is fixedly connected to a four-way tube 2129. The two ends of the four-way tube 2129 extend into the interior of the connecting tube 2122. One end of the four-way tube 2129 is fixedly connected to a second suction cup 2123. The bottom surface of the second suction cup 2123 contacts the outer surface of the blood inlet blood vessel 13, so that the first suction cup 2121 and the second suction cup 2123 pull on the blood inlet blood vessel 13, thereby temporarily expanding the inner diameter of the blood inlet blood vessel 13.

[0052] Through the above-mentioned arrangement, the present invention is provided with an expansion unit 21, so that the device can detect whether the blood inlet 13 is blocked by ultrasound. When the blood inlet 13 is detected to be blocked, the first suction cup 2121 and the second suction cup 2123 are adsorbed on the blocked position of the blood inlet 13, and then the blood inlet 13 is pulled in all directions, so that the inner diameter of the blood inlet 13 is temporarily increased, thereby allowing substances such as thrombus blocking the blood inlet 13 to pass smoothly, thereby preventing the blockage of the blood inlet 13 from affecting the patient's hemodialysis.

[0053] See also Figure 3 and Figure 4 A pulley 2124 is fixedly installed on the bottom surface of the placement rack 2108, and a slide rail 2125 is provided on the upper surface of the support plate 2104. The pulley 2124 is slidably connected to the inside of the slide rail 2125. The installation of the pulley 2124 and the slide rail 2125 serves to limit the moving trajectory of the placement rack 2108, thereby preventing the placement rack 2108 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the placement rack 2108.

[0054] See also Figure 6The upper surfaces of the two movable plates 2119 are fixedly installed with sliders 2126, and the bottom surface of the connecting plate 2116 is provided with two sliding grooves 2127. The two sliders 2126 are respectively slidably connected inside the two sliding grooves 2127. The installation of the sliders 2126 and the sliding grooves 2127 plays a role in limiting the moving trajectory of the movable plate 2119, thereby ensuring the stability of the movement of the movable plate 2119.

[0055] The specific implementation of this embodiment is as follows:

[0056] Before the patient undergoes hemodialysis, the medical staff turns on the rotary motor 2102 through the dialyzer body 11, and uses the power provided by the rotary motor 2102 to drive the support plate 2104 to adjust the angle so that the support plate 2104 points to the position where the patient's blood is drawn;

[0057] The medical staff then places the blood inlet 13 on the support plate 2104 and uses the connecting belt 2105 and the Velcro 2106 to limit and fix the blood inlet 13;

[0058] The medical staff then opens the dialyzer body 11 and uses the dialyzer body 11 to draw blood from the patient's body into the dialyzer 12. The dialyzer 12, in conjunction with the dialysate entering through the liquid inlet tube 15, filters and purifies the patient's blood. The purified blood then flows back into the patient's body through the outlet tube 14. The wastewater generated by the purification flows into the dialyzer body 11 through the liquid outlet tube 16, thereby collecting the wastewater and performing hemodialysis on the patient.

[0059] During dialysis, the power provided by the rotating motor 2110 drives the connecting gear 2109 to rotate, thereby enabling the connecting gear 2109 to cooperate with the rack plate 2107 to drive the placement rack 2108 to move on the rack plate 2107. During the movement of the placement rack 2108, the coupling agent in the storage box 2113 is pumped into the inside of the delivery tube 2115 by the delivery pump 2114, and then applied to the outer surface of the inlet blood vessel 13 through the discharge head 2112. At the same time, the ultrasonic wave emitted by the ultrasonic detector 2103 is used to detect whether the inlet blood vessel 13 is blocked.

[0060] When blockage is detected in the blood inlet 13, the rotating motor 2110 stops running, causing the placement rack 2108 to stop at the blocked position. The power provided by the electric push rod 2118 is then used to drive the two movable plates 2119 to move toward one side close to each other, so that the first suction cup 2121 is attached to the outer surface of the blood inlet 13. The power provided by the micro air pump 2117 is then used to expel the air between the first suction cup 2121, the second suction cup 2123 and the blood inlet 13, so that the first suction cup 2121 and the second suction cup 2123 are adsorbed on the outer surface of the blood inlet 13. The electric push rod 2118 then extends in the opposite direction, so that the first suction cup 2121 and the second suction cup 2123 pull the blood inlet 13, causing the blood inlet 13 at the blocked position to temporarily expand, thereby allowing substances such as thrombus to flow through the blocked position.

[0061] Example 2: Please refer to Figure 1 、 Figure 4 and Figure 7-10 The present invention provides a technical solution: a nephrology hemodialysis device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The processing mechanism 2 also includes a dredging unit 22. The dredging unit 22 is located on the left side of the dialyzer body 11. The expansion unit 21 is used in conjunction with the dredging unit 22. The dredging unit 22 is used to dredge substances such as thrombi that block the pipeline.

[0062] As a further limitation of the dredging unit 22 of the present invention, the dredging unit 22 includes a concave frame 2201, the back of the concave frame 2201 is fixedly connected to the front of the support plate 2104, the internal rotation of the concave frame 2201 is connected to the ball screw 2202, the left side of the concave frame 2201 is fixedly installed with a servo motor 2203, the output end of the servo motor 2203 is fixedly connected to the left end of the ball screw 2202, the outer surface of the ball screw 2202 is threadedly connected to the connecting block 2204, and the connecting block 2 A rectangular plate 2205 is fixedly mounted on the back of the device 204. A touch panel 2206 is fixedly mounted on the upper surface of the rectangular plate 2205. A touch switch 2207 is fixedly mounted on the inner top wall of the placement rack 2108. Two electrode plates 2208 are fixedly mounted on the back of the rectangular plate 2205. The external electrical connections of the electrode plates 2208 are connected to a device such as a power supply for providing alternating current. An electromagnetic coil 2209 is fixedly mounted on the back of the two electrode plates 2208. The electromagnetic coil 2209 is sleeved on the outside of the blood inlet blood vessel 13.

[0063] Furthermore, in the embodiment of the present invention, an electromagnet 2210 is fixedly installed on the back of the rectangular plate 2205, and the touch switch 2207 is electrically connected to the servo motor 2203 and the electrode plate 2208 through wires, so that when the touch switch 2207 is triggered, the servo motor 2203 stops running, and the electrode plate 2208 starts to provide alternating current to the electromagnetic coil 2209. A magnetic plate 2211 is provided inside the blood inlet 13, and the magnetic properties of the magnetic plate 2211 are opposite to those of the electromagnet 2210, so that the magnetic plate 2211 is magnetically connected to the electromagnet 2210. The electromagnet 2210 is attracted to the inner wall of the blood inlet blood vessel 13, and the magnetic force between the two is greater than the friction force between the magnetic plate 2211 and the blood inlet blood vessel 13, so that the electromagnet 2210 can drive the magnetic plate 2211 to move, and the outer surface of the magnetic plate 2211 contacts the inner wall of the blood inlet blood vessel 13. A fixing frame 2212 is fixedly mounted on the outer surface of the magnetic plate 2211, and a connecting bearing 2213 is fixedly mounted on the inner wall of the fixing frame 2212. A connecting column 2214 is fixedly mounted on the inner wall of the inner ring of the connecting bearing 2213, and a magnetic drill bit 2215 is fixedly mounted on the left end of the connecting column 2214;

[0064] Among them, the present invention is provided with a dredging unit 22, so that in the process of the expansion unit 21 expanding the blood vessel 13, the mutual attraction of magnetism is used to drive the magnetic drill bit 2215 to move to the blockage position, and then by inputting an alternating current, the electromagnetic coil 2209 generates a certain rotating magnetic field, and then the magnetic drill bit 2215 rotates inside the blood vessel 13, so that the magnetic drill bit 2215 breaks up and dredges the material blocking the blood vessel 13, thereby ensuring the smoothness of the blood vessel 13.

[0065] See also Figure 8 A sliding rod 2216 is fixedly installed on the inner wall of the concave frame 2201, and the outer surface of the sliding rod 2216 is slidably connected to the inner wall of the connecting block 2204. The installation of the sliding rod 2216 serves to limit the moving trajectory of the connecting block 2204, thereby preventing the connecting block 2204 from rotating during movement, thereby ensuring the stability of the movement of the connecting block 2204.

[0066] The specific implementation of this embodiment is as follows: during the process of the expansion unit 21 expanding the inlet blood vessel 13, the power provided by the servo motor 2203 is used to drive the ball screw 2202 to rotate, so that the ball screw 2202 drives the connecting block 2204 to move toward the side close to the placement rack 2108, so that the connecting block 2204 drives the rectangular plate 2205, the touch plate 2206 and the electromagnet 2210 to move, and at the same time, the magnetism between the electromagnet 2210 and the magnetic plate 2211 is used to make the electromagnet 2210 drive the magnetic plate 2211 to move toward the side close to the placement rack 2108. When 206 contacts the touch switch 2207, the servo motor 2203 stops running, so that the connecting block 2204 stops at the right side of the blocked position, and then the electrode plate 2208 cooperates with the external power supply to input alternating current to the electromagnetic coil 2209, so that a rotating magnetic field is generated inside the electromagnetic coil 2209, and then the rotating magnetic field drives the magnetic drill bit 2215 inside the blood inlet 13 to rotate, so that the magnetic drill bit 2215 breaks up the thrombus and other substances blocking the blood inlet 13, thereby cooperating with the expansion unit 21 to clear the blood inlet 13, ensuring the normal hemodialysis of the patient.

[0067] Example 3: Please refer to Figure 1 and Figure 11-13 The present invention provides a technical solution: a nephrology hemodialysis device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A crushing mechanism 3 is provided on the left side of the processing mechanism 2. The processing mechanism 2 is used in conjunction with the crushing mechanism 3. The crushing mechanism 3 is used to crush substances such as thrombus that are easy to block the pipeline.

[0068] As a further limitation of the crushing mechanism 3 of the present invention, the crushing mechanism 3 includes a connector 301, the right side of the connector 301 is fixedly connected to the left end of the blood inlet blood vessel 13, the connector 301 is fixedly connected to the patient's blood vessel through a disposable tube, a rotating shaft 302 is provided above the connector 301, and both ends of the rotating shaft 302 away from each other are fixedly mounted with a first connecting wheel 303, the outer surface of the rotating shaft 302 is fixedly mounted with a first conical wheel 304, the internal rotation of the connector 301 is connected to a turbine 305, by drawing blood from the patient, the flow of blood drives the rotation of the turbine 305, the top of the turbine 305 is fixedly mounted with a second conical wheel 306, the outer surface of the first conical wheel 304 is meshed with the outer surface of the second conical wheel 306;

[0069] Furthermore, in one embodiment of the present invention, the connector 301 is internally rotatably connected to two rotating shafts 307, and a second connecting wheel 308 is fixedly mounted on one end of the two rotating shafts 307 away from each other. Two belts 309 are sleeved on the outer surfaces of the two first connecting wheels 303 and the outer surfaces of the two second connecting wheels 308. A rotating disk 310 is fixedly mounted on one side of the two rotating shafts 307 close to each other, and a fixing column 311 is fixedly mounted on one side of the two rotating disks 310 close to each other.

[0070] Furthermore, two movable racks 312 are provided inside the connector 301, and the inner wall of each movable rack 312 is slidably connected to the outer surface of the fixed column 311, and a sliding block 313 is fixedly installed on the top of each movable rack 312, and two groups of connecting springs 314 are fixedly installed on the inner wall of the connector 301, and a thimble rack 315 is fixedly installed on the end close to each other of the two groups of connecting springs 314, and the outer surface of each sliding block 313 is slidably connected to the outer surface of the thimble rack 315. By providing the crushing mechanism 3, when the patient's blood enters the blood inlet 13, the reciprocating movement of the thimble rack 315 is utilized to cause the two thimble racks 315 to squeeze and crush substances such as thrombi in the patient's blood, thereby preventing thrombi and other substances from clogging the pipeline.

[0071] See also Figure 11 Two bearing seats 316 are fixedly installed on the upper surface of the connecting head 301. The inner walls of the two bearing seats 316 are rotatably connected to the outer surface of the rotating shaft 302. The installation of the bearing seats 316 stabilizes the rotating shaft 302, thereby preventing the rotating shaft 302 from shaking during rotation, thereby ensuring the stability of the rotating shaft 302.

[0072] See also Figure 12 Two sets of telescopic columns 317 are fixedly installed on the side of the two ejector frames 315 away from each other. The end of each telescopic column 317 away from the ejector frame 315 is fixedly connected to the inner wall of the connecting head 301. The telescopic columns 317 are located inside the connecting spring 314. The installation of the telescopic columns 317 plays a role in limiting the moving trajectory of the ejector frame 315, thereby preventing the ejector frame 315 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the ejector frame 315.

[0073] See also Figure 13 The outer surface of each mobile rack 312 is slidably connected to a limit block 318, and the side surfaces of the two limit blocks 318 that are away from each other are fixedly connected to the inner wall of the connector 301. The installation of the limit blocks 318 serves to limit the moving trajectory of the mobile rack 312, thereby ensuring the stability of the movement of the mobile rack 312.

[0074] The specific implementation of this embodiment is as follows: during hemodialysis, the blood flow drives the turbine 305 to rotate, thereby causing the turbine 305 to drive the second conical wheel 306 to rotate, and then the second conical wheel 306 drives the first conical wheel 304 to rotate, so that the first conical wheel 304 drives the rotating shaft 302 and the first connecting wheel 303 to rotate. At the same time, the first connecting wheel 303 cooperates with the belt 309 and the second connecting wheel 308 to drive the two rotating shafts 307 to rotate, so that the rotating shaft 307 drives the rotating disk 310 to rotate. When the rotating disk 310 drives the fixed column 311 to rotate, the movable frame 312 and the sliding block 313 are driven to move back and forth up and down through the restriction of the limit block 318. At the same time, due to the effect of the inclined surface of the sliding block 313, the sliding block 313 cooperates with the elastic force of the connecting spring 314 to drive the ejector frame 315 to move back and forth. Therefore, through the reciprocating movement of the two ejector frames 315, the ejector frame 315 breaks up large substances such as thrombi in the blood, thereby preventing thrombi and other substances from clogging the blood vessel 13, thereby ensuring good efficiency of the patient's hemodialysis.
