Description

Technical Field

[0001] The invention belongs to the field of medical auxiliary equipment, in particular to a double hemodialysis and hemodiafiltration blood processing device. Background Art

[0002] Patients with kidney disease rely on a variety of external blood treatments to remove harmful wastes accumulated in their blood over time. One of the most commonly used treatment methods is hemodialysis. Hemodialysis usually includes two fluid channel networks extending adjacent to each other in a countercurrent flow arrangement. Blood passes through a set of tubules and a cleaning solution passes through another set of tubules. The pH and osmotic potential of the cleaning solution are adapted so that the waste compounds accumulated in the blood diffuse from the blood into the cleaning solution via a semi-permeable membrane, and the semi-permeable membrane separates the blood and cleaning solution sides of the fluid channel network. This provides a method of gradually removing waste from the blood and minimizing the fatigue of the patient. However, there are some disadvantages associated with hemodialysis that are not present in other forms of blood treatment. It is difficult to completely remove many medium-sized and larger-sized waste solutes (including, for example, proteins and polypeptides) dissolved in the blood from the blood using diffusion alone, and it may take a long time to reduce the content of these substances in the blood to an acceptable content. An alternative method is to use hemodiafiltration. Blood treatment is not limited to diffusion because sterile cleaning solutions are allowed to mix directly with blood. However, the rapid acquisition of waste products from a patient's blood often causes fatigue in the patient.

[0003] In order to solve the above problems, a Chinese patent publication number CN 105764541 B discloses a blood treatment device, specifically, a device that can perform hemodialysis and hemodiafiltration processes. This device is implemented using an interconnected pump and valve arrangement that can be controlled to direct fluid through the dialysis membrane or parallel to the membrane depending on the type of treatment required. This allows dynamic changes between operating modes and treatments.

[0004] The device can facilitate two blood treatments during the same treatment phase based on the specific requirements of the patient, but due to different physical conditions of the patients, the dialysate has different absorption efficiencies for toxins or water in the patient's blood, and insufficient dialysis of some patients will result in low dialysis efficiency, while the dialysis effects of different patients are different. Therefore, it is necessary to set up a dual hemodialysis and hemodiafiltration blood treatment device. Summary of the invention

[0005] In order to solve the problem that insufficient dialysis of the above-mentioned patients will lead to low dialysis efficiency and different dialysis effects of different patients, the present invention provides a dual hemodialysis and hemodiafiltration blood treatment device to perform dual hemodialysis and hemodiafiltration blood treatment according to the dialysis effects of different patients, thereby improving dialysis efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a dual hemodialysis and hemodiafiltration blood treatment device, including a box body and a controller, a first treatment tank, a second treatment tank and a connecting pipe are fixedly connected in the box body, both ends of the connecting pipe are respectively connected to the first treatment tank and the second treatment tank, the top of the first treatment tank is connected to a liquid inlet pipe, the lower part of the side wall of the first treatment box is connected to a first delivery pipe, the upper part of the side wall of the first treatment box is connected to a second delivery pipe, the first delivery pipe is connected to a liquid storage tank, the liquid storage tank stores dialysate, and the second delivery pipe is connected to a waste liquid collection tank; the second treatment tank stores adsorbent, and the top of the second treatment tank is connected to a liquid outlet pipe.

[0007] A blood detection channel is connected to one end of the connecting tube near the first processing tank, a first valve is connected to the blood detection channel near one end of the connecting tube, a blood detector is connected to the blood detection channel, the blood detector is connected to the controller signal, a first auxiliary tube and a second auxiliary tube are connected to the middle of the connecting tube, a second valve is connected in the connecting tube between the first auxiliary tube and the second auxiliary tube, a third valve and a fourth valve are respectively connected to the first auxiliary tube and the second auxiliary tube near one end of the connecting tube, an end of the first auxiliary tube away from the connecting tube is connected to the auxiliary processing tank, the first auxiliary tube is connected to the top of the auxiliary processing tank, a side of the auxiliary processing tank is connected to a proportioning assembly and a waste liquid delivery pipe, the proportioning assembly is located below the waste liquid delivery pipe, an end of the waste liquid delivery pipe away from the auxiliary processing tank is connected to the second delivery pipe, and a bottom end of the auxiliary processing tank is connected to the second auxiliary tube.

[0008] The batching component includes a batching box, the top of the batching box is connected with a water outlet pipe and a plurality of storage boxes, the storage boxes store hemodialysis fluid raw material powder, the connection points between the storage boxes and the batching box are connected with a fifth valve, the water outlet pipe is connected with a sixth valve, the top of the batching box is fixedly connected with a driving member, the output shaft of the driving member passes through the top of the batching box and extends into the batching box, the output shaft of the driving member is coaxially fixedly connected with a stirring shaft, and a plurality of stirring blades are fixedly connected to the stirring shaft; the bottom of the batching box is connected with a discharge pipe, the batching box is connected with an auxiliary processing tank through the discharge pipe, and the discharge pipe is connected with a seventh valve near one end of the batching box; the first valve, the second valve, the third valve, the fourth valve, the fifth valve, the sixth valve and the seventh valve are all connected with controller signals.

[0009] Principle and beneficial effects of the above scheme: before using the device, the first valve, the second valve, the third valve, the fourth valve, the fifth valve, the sixth valve and the seventh valve are all in a closed state.

[0010] When using this device, blood is input into the first treatment box through the liquid inlet tube. At this time, the liquid storage tank transports dialysate to the first treatment box through the first delivery tube. After the blood is dialyzed by the dialysate, it is output from the connecting tube at the bottom of the first treatment box. The used dialysate is output to the waste liquid collection box through the second delivery tube, thereby completing the first dialysis.

[0011] The first valve and the second valve are opened. Since the blood detection channel is connected to the end of the connecting tube close to the first treatment tank, the blood output from the first treatment tank will flow into the blood detection channel, thereby using the blood detector to detect the blood after the first dialysis. Since the blood detector is connected to the controller signal, the blood detector transmits the detected blood information to the controller, and the controller determines whether the toxins or excess water in the blood are fully discharged.

[0012] If it is detected that the toxins or excess water in the blood have been fully discharged, the second valve is kept open to allow the blood to be input into the second processing tank through the connecting tube. The adsorbent in the second processing tank adsorbs the blood, and the adsorbed blood is output from the top of the second processing tank.

[0013] If it is detected that toxins or excess water in the blood are not fully discharged, the second valve is closed, and the third and fourth valves are opened at the same time to allow the blood to flow into the auxiliary treatment tank. Since the fifth and sixth valves are both connected to the controller signal, the controller controls the amount of different hemodialysis fluid raw material powders and water added to the storage box by controlling the opening time and opening size of the fifth valve.

[0014] After the raw material powder and water of the hemodialysis fluid are added into the storage box, the controller controls the driving part to operate. Since the stirring shaft is coaxially fixedly connected with the output shaft of the driving part, the stirring shaft is driven to rotate when the output shaft of the driving part rotates. Since a number of stirring blades are fixedly connected to the stirring shaft, the stirring blades are driven to rotate when the stirring shaft rotates, thereby fully stirring and mixing the raw material powder and water of the hemodialysis fluid, thereby preparing the special hemodialysis fluid.

[0015] Open the seventh valve. Since there is a discharge pipe at the bottom of the batching box, the batching box is connected to the auxiliary treatment tank through the discharge pipe. Therefore, the special hemodialysis fluid is input into the auxiliary treatment tank through the discharge pipe at this time, and the blood in the auxiliary treatment tank is dialyzed again. In this way, the blood is dialyzed again according to the dialysis effect of different patients, thereby improving the dialysis efficiency.

[0016] Furthermore, a plurality of supports are fixedly connected to the bottom of the box.

[0017] Beneficial effects: The support can support the device, improve the heat dissipation effect at the bottom of the device, and make the heat dissipation performance better. At the same time, it can prevent the device from sliding and improve stability. The support can increase the height of the device and prevent ground dust or impurities from entering the box, causing damage or pollution to the box.

[0018] Furthermore, the bottom walls of the first processing tank and the second processing tank are both arc-shaped.

[0019] Beneficial effect: The bottom walls of the first processing tank and the second processing tank are both arc-shaped, which can facilitate the input and output of blood at the bottom of the first processing tank and the second processing tank.

[0020] Furthermore, a rubber layer is fixedly connected to the bottom of the support.

[0021] Beneficial effects: The rubber layer can effectively reduce the vibration and impact at the bottom of the support, making the device more stable and safer. Rubber has good sound insulation performance, which can reduce the noise generated by the operation of mechanical equipment and ensure a quiet and comfortable working environment. The rubber layer can prevent the bracket from directly contacting the ground, avoiding wear or scratches on the ground, and protecting the cleanliness and beauty of the ground. The rubber layer has excellent anti-slip performance, which can increase the friction coefficient of the support, making it more stable and safe, and reducing accidents caused by sliding.

[0022] Furthermore, the first delivery pipe is connected to an eighth valve at one end near the first processing tank, the middle of the first delivery pipe is connected to a first spare pipe, the first spare pipe is connected to the first processing tank at one end away from the first delivery pipe, and the first spare pipe is connected to a ninth valve at one end near the first processing tank. Both the eighth valve and the ninth valve are connected to the controller signal.

[0023] Beneficial effect: When using the first delivery pipe, the ninth valve is opened and the eighth valve is closed at the same time, so that the dialysate in the first delivery pipe can be input into the first treatment tank through the first delivery pipe and the first spare pipe, thereby enabling emergency delivery after the first delivery pipe is blocked.

[0024] Furthermore, the second delivery pipe is connected to a tenth valve at one end near the first processing tank, a second spare pipe is connected to the middle of the second delivery pipe, the second spare pipe is connected to the first processing tank away from one end of the second delivery pipe, and an eleventh valve is connected to one end of the second spare pipe near the first processing tank. Both the tenth valve and the eleventh valve are connected to the controller signal.

[0025] Beneficial effect: When using the second delivery pipe, the eleventh valve is opened and the tenth valve is closed at the same time, so that the dialysate waste in the first treatment tank can be input into the waste liquid collection box through the second spare pipe and the second delivery pipe, thereby enabling emergency delivery after the second delivery pipe is blocked.

[0026] Furthermore, a guide block is fixedly connected to the bottom of the batching box, the top surface of the guide block is an inclined surface, and the height of the guide block close to the discharge pipe is lower than the height of the guide block away from the discharge pipe.

[0027] Beneficial effect: The guide block can facilitate the diversion of materials in the batching box, facilitate the discharge of materials from the discharge pipe, and avoid material residue in the batching box.

[0028] Furthermore, a cover body is hinged on the top of the storage box, and a handle is fixedly connected to the cover body.

The middle of the connecting tube 5 is connected to a first auxiliary tube 15 and a second auxiliary tube 16. A second valve 32 is connected in the connecting tube 5 between the first auxiliary tube 15 and the second auxiliary tube 16. The first auxiliary tube 15 and the second auxiliary tube 16 are respectively connected to a third valve 33 and a fourth valve 34 near one end of the connecting tube 5. The first auxiliary tube 15 is connected to an auxiliary processing tank 17 at one end away from the connecting tube 5. The first auxiliary tube 15 is connected to the top of the auxiliary processing tank 17. One side of the auxiliary processing tank 17 is connected to a batching component and a waste liquid conveying pipe 18. The batching component is located below the waste liquid conveying pipe 18. The end of the waste liquid conveying pipe 18 away from the auxiliary processing tank 17 is connected to the second conveying pipe 8, and the bottom of the auxiliary processing tank 17 is connected to the second auxiliary tube 16.

[0038] The batching assembly includes a batching box 19, the top of which is connected to a water outlet pipe 20 and a plurality of storage boxes 21, the storage box 21 stores raw material powder of hemodialysis fluid, the connection between the storage box 21 and the batching box 19 is connected to a fifth valve 35, the water outlet pipe 20 is connected to a sixth valve 36, the top of the batching box 19 is fixedly connected to a driving member 23 by screws, the output shaft of the driving member 23 passes through the top of the batching box 19 and extends into the batching box 19, the output shaft of the driving member 23 is coaxially fixedly connected to a stirring shaft 24, and a plurality of stirring blades 25 are fixedly connected to the stirring shaft 24. The driving member is a motor. The bottom of the batching box 19 is connected with a discharge pipe 26, and the batching box 19 is connected with the auxiliary processing tank 17 through the discharge pipe 26. The discharge pipe 26 is connected with a seventh valve 37 at one end close to the batching box 19; the first valve 31, the second valve 32, the third valve 33, the fourth valve 34, the fifth valve 35, the sixth valve 36 and the seventh valve 37 are all connected to the controller 2 by signal. The first valve 31, the second valve 32, the third valve 33, the fourth valve 34, the fifth valve 35, the sixth valve 36 and the seventh valve 37 are preferably valves in the Chinese patent announcement number CN 105764541B.

[0039] The specific implementation process is as follows: before using the device, the first valve 31, the second valve 32, the third valve 33, the fourth valve 34, the fifth valve 35, the sixth valve 36 and the seventh valve 37 are all in a closed state.

[0040] When using the device, blood is input into the first treatment box through the liquid inlet pipe 6. At this time, the liquid storage tank 9 transports dialysate to the first treatment box through the first delivery pipe 7. After the blood is dialyzed by the dialysate, it is output from the connecting pipe 5 at the bottom of the first treatment box. The used dialysate is output to the waste liquid collection box 10 through the second delivery pipe 8, thereby completing the first dialysis.

[0041] The first valve 31 and the second valve 32 are opened. Since the blood detection channel 13 is connected to the end of the connecting tube 5 close to the first treatment tank 3, the blood output through the first treatment tank 3 will flow into the blood detection channel 13, and the blood after the first dialysis is detected by the blood detector 14. The blood detector 14 transmits the detected blood information to the controller 2, and the controller 2 determines whether the toxins or excess water in the blood are fully discharged.

[0042] If it is detected that the toxins or excess water in the blood have been fully discharged, the second valve 32 is continuously opened to allow the blood to be input into the second treatment tank 4 through the connecting tube 5. The adsorbent 12 in the second treatment tank 4 adsorbs the blood, and the adsorbed blood is output from the liquid outlet pipe 11 at the top of the second treatment tank 4.

[0043] If it is detected that toxins or excess water in the blood are not fully discharged, the second valve 32 is closed, and the third valve 33 and the fourth valve 34 are opened at the same time to allow the blood to flow into the auxiliary treatment tank 17. The controller 2 controls the amount of different hemodialysis fluid raw material powders and water added to the storage box 21 by controlling the opening time and opening size of the fifth valve 35.

[0044] After the raw material powder and water of the hemodialysis fluid are added into the storage box 21, the controller 2 controls the driving member 23 to operate, and the output shaft of the driving member 23 rotates to drive the stirring shaft 24 to rotate. Since a plurality of stirring blades 25 are fixedly connected to the stirring shaft 24, the stirring blades 25 are driven to rotate when the stirring shaft 24 rotates, thereby fully stirring and mixing the raw material powder and water of the hemodialysis fluid, thereby preparing the special hemodialysis fluid.

[0045] The seventh valve 37 is opened. Since the bottom of the batching box 19 is connected to the discharge pipe 26, the batching box 19 is connected to the auxiliary treatment tank 17 through the discharge pipe 26. Therefore, the special hemodialysis fluid is input into the auxiliary treatment tank 17 through the discharge pipe 26 at this time, and the blood in the auxiliary treatment tank 17 is dialyzed again. In this way, double hemodialysis and hemodiafiltration blood treatment are performed according to the dialysis effect of different patients, thereby improving the dialysis efficiency.
