Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis, and in particular to a blood pressurization ultrafiltration device for nephrology. Background Art

[0002] In the development of biomedical engineering, hemodialysis machines are a method of treating patients with chronic kidney disease. When a patient's kidney function is severely damaged or fails, the waste and excess fluid produced in the body cannot be effectively eliminated. Hemodialysis can assist in removing these wastes and fluids and help maintain the body's water and electrolyte balance.

[0003] Chinese patent CN115227894A discloses a pressurized ultrafiltration device for nephrology, including an outer shell, a pressurized ultrafiltration mechanism is installed inside the outer shell, and a pressure gauge is fixedly installed at a position corresponding to the pressurized ultrafiltration mechanism on the side end face of the outer shell, and the end of the pressure gauge is installed on the pressurized ultrafiltration mechanism, and the pressurized ultrafiltration mechanism is provided with a first heat preservation and anti-blocking mechanism and a second heat preservation and anti-blocking mechanism. By utilizing the piston movement behavior of two piston discs in the mutually reverse state in two inner tanks, human blood can be continuously drawn to a certain extent, and the blood after ultrapressure filtration treatment can be reintroduced into the human body during the process of drawing human blood, realizing the closed-loop ultrafiltration treatment of human blood, so that on the basis of ensuring good ultrafiltration treatment of human blood, the stability of blood pressure in the human body is also ensured, avoiding affecting the stability of human blood pressure when ultrafiltration treatment is performed on blood of kidney patients.

[0004] The above patents and prior art have the following problems:

[0005] In existing dialysis equipment, a peristaltic pump is used to draw the patient's blood into the dialyzer. When the peristaltic pump draws blood, water hammer pulsation will be generated. If the water hammer pulsation is not eliminated, it will affect the patient's blood transfusion. If a buffer chamber is added to the blood collection tube, the manufacturing cost of the blood collection tube will increase, and the blood collection tube cannot be recycled, thereby causing a waste of resources. In actual use, the filter can only passively wait for the blood to contact the dialysis membrane and dialysate. The overall waste replacement efficiency is not high, and the filter will also be affected by the air mixed in the dialysate. After the air is transferred to the blood by the dialysate, it will be transferred to the patient, thereby endangering the patient's health. Summary of the invention

[0033] Beneficial effects of the present invention:

[0034] When the peristaltic power element is started, the driving source is started in coordination, so that the driving source drives the base to move up and down, so that the liquid inside the dialyzer produces relative shaking during the up and down movement of the base, thereby increasing the exchange frequency between the dialyzer inside the dialyzer cavity and the blood inside the blood cavity, and also increasing the contact efficiency between the blood and the dialyzer membrane surface. The up and down movement of the dialyzer also causes the attachments on the dialyzer membrane surface to be shaken off by the up and down movement, thereby increasing the area of ​​the dialyzer membrane for the dialyzer to pass through.

[0035] When the dialysate moves upward or downward, the soft connecting part will be pulled to contract, so that the soft connecting part drives the penetration rod to move inward, thereby the penetration rod drives the dynamic slow plate to approach the fixed slow plate, so that the up and down shaking of the extraction and insertion tube is restricted, and the movement of the dynamic slow plate will also drive the hook connecting rod to move, so that the hook connecting rod will also drive the rolling wheel in the high section along the connecting section to the inside of the low section as the dynamic slow plate moves, thereby lowering the height of the hook connecting rod, so that the hook connecting rod drives the closing slow plate to approach the back slow plate, thereby restricting the forward and backward shaking of the extraction and insertion tube, and then when the dialysate moves to the uppermost or lowermost end of the movable groove, the back slow plate, the fixed slow plate, the dynamic slow plate and the closing slow plate will enclose a movable sealed space, so that the enclosed movable sealed space can move up and down with the dialysate, thereby continuously narrowing the range of movement of the extraction and insertion tube and the infusion tube, thereby reducing the shaking of the extraction and insertion tube and the infusion tube caused by the up and down movement of the dialysate.

[0036] By controlling the movement of the driving source and the peristaltic power part, when the driving source controls the base to reach the highest end of the movable groove, the peristaltic power part will drive the rotating arm to rotate, so that the rotating arm drives the extrusion wheel to squeeze the insertion tube, so that the insertion tube is drawn blood by the extrusion wheel and water hammer pulsation driven by the extrusion will also be generated. When the concave slow plate arranged on the left side of the horizontal slow plate and the convex plate on the left side of the dynamic slow plate enclose a space, the insertion tube will be bent in an arc, so that the water hammer pulsation generated in the insertion tube will be concentrated at the bending part, and the back slow plate, the fixed slow plate, the dynamic slow plate and the closed slow plate form a movable sealing The space will contact the bending part of the suction and insertion tube, and then on the basis of the elastic material composition of the back buffer plate, the fixed buffer plate, the dynamic buffer plate and the closing buffer plate, the water hammer pulsation inside the suction and insertion tube will be buffered. When the dialysis component moves to the highest end, the movable sealed space surrounded by the back buffer plate, the fixed buffer plate, the dynamic buffer plate and the closing buffer plate will have a height difference and inclination angle with the dialysis component at the highest end, so that the suction and insertion tube between the two will be tilted upward, and under the influence of the tilted upward suction and insertion tube, the water hammer pulsation inside the suction and insertion tube will be further buffered, thereby reducing the impact on the patient.

[0037] The pressure plate moves up and down, which will push the liquid inside the treatment tank to turn up and down driven by the pressure plate, and the liquid inside the treatment tank will move up and down in the dispersion hole, and continuously pass through the dispersion hole. The liquid passing through the dispersion hole will also drive the dispersion blades to rotate, so that the dispersion blades stir and disperse the liquid passing through the dispersion hole, thereby improving the combination efficiency of the dialysis concentrate and the pure water. The stirring and dispersion of the liquid will also stir and combine the gas inside the liquid, and then be extracted and discharged by the exhaust component on the top of the treatment tank, thereby reducing the air content inside the liquid;

[0038] The winding power member drives the winding roller to wind up the pulling member, and the pulling member drives the sealing plate to fit the bottom surface of the pressure plate member, so that the sealing plate seals the bottom surface of the dispersion hole, and when the pressure plate member moves downward, the winding power member releases the pulling member synchronously with the movement of the base. In this process, the sealing plate always fits the bottom of the pressure plate member, so that the pressure plate member is sealed, and the sealed pressure plate member squeezes the mixed liquid downward along with the folding connecting rod. At this time, the solenoid valve is opened, and the pressurized liquid is buffered by the buffer plate and the buffer member, and is transported to the inside of the dialysis member by the input tube to pressurize the liquid inside the dialysis member, so that the dialysate is pressurized and contacts the blood, thereby improving the contact efficiency of the dialysate passing through the dialysis membrane with the blood, and then improving the effect of pressurized filtration.

[0077] When the dialyzer 104 moves upward or downward, the soft connector 2051 will be pulled to contract, so that the soft connector 2051 drives the penetrating rod 10821 to move inward, so that the penetrating rod 10821 drives the dynamic slow plate 1082 to approach the fixed slow plate 1081, so that the up and down shaking of the insertion tube 1061 is restricted, and the movement of the dynamic slow plate 1082 will also drive the hook rod 10831 to move, so that the hook rod 10831 will also drive the rolling wheel 10832 in the high section 2041 along the connecting section 2042 to the inside of the low section 2043 as the dynamic slow plate 1082 moves, so that the height of the hook rod 10831 is reduced, so that the hook rod 10831 drives the closing slow plate 1083 to approach the back slow plate 108, so that the front and rear shaking of the insertion tube 1061 is restricted, and then when the dialyzer 104 moves to the movable groove 1011 After reaching the top or bottom of the dialysate 104, the back slow plate 108, the fixed slow plate 1081, the dynamic slow plate 1082 and the closed slow plate 1083 will enclose a movable sealed space, so that the enclosed movable sealed space can move up and down with the dialysate 104, thereby continuously reducing the range of movement of the extraction and insertion tube 1061 and the delivery and insertion tube 1062, thereby reducing the shaking of the extraction and insertion tube 1061 and the delivery and insertion tube 1062 caused by the up and down movement of the dialysate 104. It should be noted that, by designing the length of the movable groove 1011 and the length of the soft connector 2051, the movable sealed space enclosed by the back slow plate 108, the fixed slow plate 1081, the dynamic slow plate 1082 and the closed slow plate 1083 is matched with the diameter of the extraction and insertion tube 1061 and the delivery and insertion tube 1062, so that the enclosed sealed space will not excessively squeeze the tube walls of the extraction and insertion tube 1061 and the delivery and insertion tube 1062;

[0078] By controlling the movement of the driving source 201 and the peristaltic power piece 202, when the driving source 201 controls the base 205 to reach the highest end of the movable groove 1011, the peristaltic power piece 202 will drive the rotating arm 1072 to rotate, so that the rotating arm 1072 drives the squeezing wheel 1073 to squeeze the insertion tube 1061, so that the insertion tube 1061 is drawn blood by the squeezing wheel 1073 and water hammer pulsation driven by squeezing will also be generated. When the concave slow plate 10813 arranged on the left side of the horizontal slow plate 10811 and the convex plate on the left side of the dynamic slow plate 1082 enclose a space, the insertion tube 1061 will generate an arc bend, and the water hammer pulsation generated in the insertion tube 1061 will be concentrated at the bend, and the back slow plate 108, the fixed slow plate 1081, the dynamic slow plate 1082 and the closing slow plate 108 will cause the insertion tube 1061 to generate an arc bend. The movable sealed space enclosed by the plate 1083 will contact the bending part of the extraction and insertion tube 1061, and then on the basis of the elastic material composition of the back slow plate 108, the fixed slow plate 1081, the dynamic slow plate 1082 and the closed slow plate 1083, the water hammer pulsation inside the extraction and insertion tube 1061 will be buffered. When the dialysis element 104 moves to the highest end, the movable sealed space enclosed by the back slow plate 108, the fixed slow plate 1081, the dynamic slow plate 1082 and the closed slow plate 1083 will have a height difference and inclination angle with the dialysis element 104 at the highest end, so that the extraction and insertion tube 1061 between the two is tilted upward, and under the influence of the tilted upward extraction and insertion tube 1061, the water hammer pulsation inside the extraction and insertion tube 1061 is further buffered, thereby reducing the impact on the patient.

[0089] The rest of the structure is the same as that of Example 1.

[0090] Operation process:

[0091] The up and down movement of the base 205 will also drive the folding connecting rod 2032 to move up and down, and when the folding connecting rod 2032 moves up and down, it will drive the pressure plate 304 to move up and down inside the treatment tank 301. When the pressure plate 304 moves up and down inside the treatment tank 301, it will mix the dialysate and purified water transported to the treatment tank 301 through the through pipe 203. That is, the up and down movement of the pressure plate 304 will push the liquid inside the treatment tank 301 to be turned up and down by the pressure plate 304, and the liquid inside the treatment tank 301 will be in the dispersion hole 301. 41 moves up and down, continuously passing through the dispersion hole 3041, and the liquid passing through the dispersion hole 3041 will also drive the dispersion leaf 3053 to rotate, so that the dispersion leaf 3053 stirs and disperses the liquid passing through the dispersion hole 3041, thereby improving the combination efficiency of the dialysis concentrate and the pure water, and the stirring and dispersion of the liquid will also stir and combine the gas inside the liquid, and then be sucked out and discharged by the suction piece 3011 on the top of the processing tank 301, thereby reducing the air content inside the liquid. It should be noted that the liquid level inside the processing tank 301 will not reach the suction chamber 3015;

[0092] In the above process, the solenoid valve 1053 is in a closed state, and the dispersion leaf 3053 inside the dispersion hole 3041 is pressed down by the weight of the annular member 305 and the sealing disk 3054, so that the sealing disk 3054 does not contact the bottom of the pressure plate member 304, and when the liquid inside the processing tank 301 is mixed for a predetermined time, the pressure plate member 304 is located at the top of the dispersion chamber 3014, so that the winding power member 3031 drives the winding roller 303 to wind up the pulling member 3032, so that the pulling member 3032 drives the sealing disk 3054 to fit the bottom surface of the pressure plate member 304, so that the sealing disk 3054 seals the bottom surface of the dispersion hole 3041, and when the pressure plate member 304 moves downward, the winding power member 3031 releases the pulling member 3032 synchronously with the movement of the base 205. During this process, the sealing plate 3054 always fits the bottom of the pressure plate 304, so that the pressure plate 304 is sealed, and the sealed pressure plate 304 squeezes the mixed liquid downward along with the folding connecting rod 2032. At this time, the solenoid valve 1053 is opened, and the pressurized liquid passes through the buffer plate 3017 and the buffer member 3018, and is transported to the inside of the dialyzer 104 by the input tube 1051 to pressurize the liquid inside the dialyzer 104, so that the dialysate is pressurized and contacts the blood, thereby improving the dialysate's contact efficiency with the blood through the dialyzer membrane 1045, and thereby improving the effect of pressurized filtration.

[0093] The driving source 201 drives the dialysate 104 to move through the base 205, which will improve the combination effect of the dialysate and blood, reduce the shaking of the extraction and insertion tube 1061 and the delivery and insertion tube 1062 during the movement of the dialysate 104, and at the same time buffer the water hammer pulsation generated inside the extraction and insertion tube 1061. The base 205 will also drive the dialysate and pure water to combine, and pressurize and filter the inside of the dialysate 104, thereby making the equipment structure more compact, thereby reducing the use of power equipment.
