Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to a hemodialysis blood circuit tube for convenient replacement of an arteriovenous pot. Background Art

[0002] Hemodialysis is one of the most commonly used renal replacement therapies for end-stage renal disease. As an extracorporeal circulation treatment, hemodialysis is highly susceptible to coagulation during the extracorporeal circulation, with high venous pressure alarms being a common cause. For these patients, blood is extremely precious. If left untreated, it can lead to varying degrees of anemia, compromising dialysis effectiveness and increasing the patient burden. Therefore, ensuring smooth hemodialysis and timely and effective treatment of coagulation play a crucial role in ensuring dialysis treatment effectiveness and improving patients' quality of life and survival rates.

[0003] Hemodialysis extracorporeal circuits utilize arterial and venous cuffs, as well as arteriovenous tubing. During dialysis, clots can occur for a variety of reasons, but arterial clots are relatively rare. The most common cause of clots is venous clots within the cuffs. This manifests as increased pressure and hardening of the arterial tubing, a darker, darker color of blood in the venous tubing, and a significant increase in venous pressure, often reaching around 400 mmHg or exceeding the maximum value. The blood in the venous cuff darkens and blackens, and the blood pump stops. If not addressed promptly, approximately 200 ml of blood circulating in the patient's extracorporeal circuit will clot and become incapable of return to the patient.

[0004] In the prior art, the arteriovenous pot and the pipeline are generally an integrated structure and cannot be separated separately. In this way, if blood coagulates in the pot, embolism is likely to occur, causing the entire pipeline to be blocked and scrapped, and the pipeline needs to be replaced, which is not only very wasteful but also affects hemodialysis.

[0068] The hemodialysis blood circuit tube for convenient replacement of an arteriovenous pot according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0069] Reference Figures 1 to 4 As shown, the hemodialysis blood circuit tube for convenient replacement of arteriovenous pots provided in an embodiment of the present invention includes a dialyzer 10, an arterial pot 20, an arterial line 30, a venous pot 40 and a venous line 50.

[0070] The dialyzer 10 may be a dialyzer 10 commonly used in the prior art for purifying blood.

[0071] The artery pot 20 includes a fixing seat 21 and an artery pot body 22. The fixing seat 21 is detachably connected to the artery pot body 22 and is used to fix the artery pot body 22.

[0072] The arterial line 30 includes a first arterial tube 31, a blood pump 32 and a second arterial tube 33; one end of the first arterial tube 31 is connected to the human body, and the other end is detachably connected to the arterial pot body 22; the blood pump 32 is arranged on the first arterial tube 31; one end of the second arterial tube 33 is detachably connected to the arterial pot body 22, and the other end is connected to the dialyzer 10.

[0073] The arterial pot 20 serves as a transit structure and is arranged between the first arterial tube 31 and the second arterial tube 33 of the arterial pipeline 30. It can stabilize hemodynamics, control blood pressure, correct electrolyte imbalance, and remove toxins. It includes a fixing seat 21 and an arterial pot body 22, wherein the fixing seat 21 can be fixed on the external structure and detachably connected to the arterial pot body 22. Therefore, the fixing seat 21 can detachably fix the arterial pot body 22, which makes the arterial pot body 22 and the pipeline not easy to be pulled, and also makes the arterial pot body 22 detachable. The arterial line 30 includes a first arterial line 31, a blood pump 32, and a second arterial line 33. The blood pump 32 extracts arterial blood, which is then transferred to the arterial chamber 22 via the first arterial line 31 and then to the dialyzer 10 via the second arterial line 33 for purification. The arterial chamber 22 is detachably connected to the first and second arterial lines 31, 33. Therefore, the arterial chamber 22 can be separated from the first and second arterial lines 31, 33 and subsequently disassembled as needed. In this embodiment, the arterial chamber 22 and the first and second arterial lines 31, 33 can be connected using medical-grade Luer locks of various specifications, providing convenient assembly and disassembly and excellent sealing. Furthermore, the arterial chamber 22 can be accurately and quickly connected to the first and second arterial lines 31, 33, preventing incorrect installation orientation. In addition, there is a detachable auxiliary connecting tube between the first arterial tube 31 and the second arterial tube 33, which can replace the arterial pot body 22 to connect with the first arterial tube 31 and the second arterial tube 33. In this way, when the arterial pot body 22 needs to be removed, the first arterial tube 31 and the second arterial tube 33 can still be connected through the auxiliary connecting tube to ensure the transmission of arterial blood.

[0074] The intravenous pot 40 includes a mounting base and an intravenous pot body, wherein the mounting base is detachably connected to the intravenous pot body and is used to fix the intravenous pot body. The intravenous line 50 includes a first intravenous tube 51, a second intravenous tube 52, and a shunt tube 53. One end of the first intravenous tube 51 is connected to the human body and the other end is detachably connected to the intravenous pot body. One end of the second intravenous tube 52 is detachably connected to the intravenous pot body and the other end is connected to the dialyzer 10. One end of the shunt tube 53 is detachably connected to the first intravenous tube 51 and the other end is detachably connected to the second intravenous tube 52.

[0075] The venous pot 40 serves as a transit structure and is arranged between the first venous tube 51 and the second venous tube 52 of the venous line 50. It can stabilize hemodynamics, control blood pressure, etc. It includes a mounting seat and a venous pot body, wherein the mounting seat can be fixed on the external structure and detachably connected to the venous pot body. Therefore, the mounting seat can detachably fix the venous pot body, which makes the venous pot body not easily pulled and also makes the venous pot body detachable. The venous line 50 includes a first venous line 51, a second venous line 52 and a branch line 53, wherein the first venous line 51, the venous pot body and the second venous line 52 form a main line and are directly connected to the dialyzer 10. In this way, the blood purified by the dialyzer 10 can be returned to the patient's body through the main line, and the branch line is connected to the first venous line 51 and the second venous line 52. Therefore, the blood purified by the dialyzer 10 can also be returned to the patient's body through the second venous line 52, the branch line and the first venous line 51. In this way, when coagulation or other conditions that affect blood transfusion occur in the venous pot body on the main line, the branch line can be connected to the pipe. At this time, the venous pot body can be removed from the first venous line 51 and the second venous line 52 for replacement, and the branch line can be connected to continue blood return. In this way, the blood transfusion process will not be interrupted. In this embodiment, the venous pot body and the first venous tube 51 and the second venous tube 52 can be connected using medical-grade Luer locks of different specifications. They are easy to assemble and disassemble and have good sealing. At the same time, they can be accurately and quickly connected to the first venous tube 51 and the second venous tube 52 to avoid incorrect installation direction.

[0076] More specifically, when the present application is in use, the first arterial tube 31 and the first venous tube 51 can be connected to the human artery and vein, so that the first arterial tube 31, the arterial pot body 22, the second arterial tube 33, the dialyzer 10, the second venous tube 52, the venous pot body and the first venous tube 51 form a complete blood flow channel. When hemodialysis is required, the arterial pot body 22 and the venous pot body can be fixed through the corresponding fixing seat 21 and the mounting seat, and then the blood pump 32 is turned on to transfer the arterial blood through the first arterial tube 31, the arterial pot body 22, and the second arterial tube 33 to the dialyzer 10. After purification by the dialyzer 10, the blood is returned to the patient's body through the second venous tube 52, the venous pot body and the first venous tube 51. In this way, the patient's blood can be purified and then returned. During this process, the condition of the blood is judged by observing the conditions of the arterial pot body 22 and the venous pot body. If coagulation or other conditions that affect hemodialysis are found, the arterial pot body 22 and the venous pot body can be closed, and the auxiliary connecting tube and the branch line can be connected to the arterial line 30 and the venous line 50. Hemodialysis can still be carried out while the arterial pot body 22 and the venous pot body are replaced.

[0077] According to the hemodialysis blood circuit tube of the convenient replacement of arteriovenous pot provided by the present invention, the arterial pot body 22 and the venous pot body can be fixed on the external structure to prevent them and the corresponding pipelines from being pulled and affecting their use; at the same time, the arterial pot body and the venous pot body are detachably connected to the pipeline, so that they can be quickly replaced separately when coagulation occurs without having to replace the entire body, which is convenient for use.

[0078] Advantageously, in one embodiment of the present invention, the fixing seat 21 and the mounting seat both include a U-shaped member 211 , an adjusting tube 212 and a clamping member 213 ;

[0079] The surface of the U-shaped member 211 is provided with an adhesive layer 2111, and the adhesive layer 2111 is used to adhere and fix the U-shaped member 211;

[0080] The regulating tube 212 is a bellows, one end of which is connected to the middle of the U-shaped member 211 and the other end is connected to the clamping member 213;

[0081] The clamping member 213 is used to clamp and fix the arterial pot body 22 and the venous pot body.

[0082] The fixing seat 21 is used to fix the venous pot body and the arterial pot body 22 to avoid, which specifically includes a U-shaped part 211, an adjusting tube 212 and a clamping part 213, wherein an adhesive layer 2111 is provided on the outer wall of the U-shaped part 211, and the adhesive layer 2111 can be a medical adhesive with good adhesive effect. The U-shaped part 211 can be adhered to the surface of an object, such as the outer wall of a dialysis machine, through the adhesive. Of course, it can also be other positions. The adjusting tube 212 adopts a corrugated tube. Therefore, after bending it, it can be adjusted to different positions. Correspondingly, the clamping part 213 provided thereon can also be adjusted to different positions. Then, the venous pot body or the arterial pot body 22 clamped on the clamping part 213 can also be adjusted to different positions, for example, adjusted to a position that is not easy to collide, which can prevent the venous pot body or the arterial pot body 22 from being accidentally pulled; adjusted to different heights, it can be convenient for medical staff of different heights to observe, etc.

[0083] Advantageously, in another embodiment of the present invention, an inverted L-shaped hanging piece 221 is provided on the side walls of the arterial pot body 22 and the venous pot body, and the inverted L-shaped hanging piece 221 is detachably mounted on the mounting piece 213 .

[0084] Specifically, a locking hole 2131 is provided on the locking member 213, and an elastic pad is provided on the inner wall of the locking hole 2131. In this way, by inserting the inverted L-shaped hanger into the locking hole 2131, the arterial pot body 22 and the venous pot body can be fixed and fixed. To a certain extent, this can prevent the arterial pot body 22 and the venous pot body from being pulled and affecting their use. The elastic pad in the locking hole 2131 can be clamped by the inverted L-shaped hanger, so that the arterial pot body 22 and the venous pot body are fixed at the corresponding height, which is convenient for use. Preferably, the arterial pot body 22 and the venous pot body are both made of transparent material, and reference scale lines are provided on the outer wall, and the reference scale lines can be used to easily identify the location of the thrombus.

[0085] Advantageously, in one embodiment of the present invention, a visual amplifying member 23 is further included. The visual amplifying member 23 has a detachable cover which is disposed outside the arterial pot body 22 and the venous pot body and is detachably connected to the clamping member 213 .

[0086] Preferably, the visual amplifying member 23 includes a curved magnifying lens 231 and a clamping rod 232;

[0087] The clamping rod 232 is vertically arranged at one end of the arc-shaped magnifying lens 231 and is detachably rotatably connected to the clamping hole 2131 on the clamping member 213, so as to cover the arc-shaped magnifying lens 231 outside the arterial pot body 22 and the venous pot body.

[0088] The visual magnification component can visually magnify the venous and arterial chambers 22. This allows for the visual magnification component to amplify blood clots, especially small clots, within the venous or arterial chambers 22, allowing medical personnel to quickly identify and replace them. The curved magnifying lens 231 of the visual magnifying component 23 can be made of plastic, which is lightweight, low-cost, and provides excellent magnification. The curved magnifying lens is removably attached to the mounting member 213 via a latch 232, allowing for easy assembly and disassembly. Furthermore, the latch 232 is rotatably connected to the latch hole 2131 on the mounting member, allowing the curved magnifying lens 231 to be rotated. This allows for easy replacement of the arterial or venous chambers without removing the curved magnifying lens 231. Simply rotating the lens 231 a certain angle allows for easy assembly and disassembly. Once the venous or arterial chambers are in place, the lens can be conveniently rotated back to its position outside the arterial or venous chambers.

[0089] Advantageously, in some embodiments of the present invention, the branch pipe 53 includes a first conduit 531 , a second conduit 532 and an auxiliary pot body 533 ;

[0090] One end of the first conduit 531 is connected to the first venous tube 51 , and the other end is connected to the auxiliary kettle body 533 ;

[0091] One end of the second conduit 532 is connected to the auxiliary kettle body 533 , and the other end is connected to the second venous tube 52 ;

[0092] A filter layer is provided inside the auxiliary pot body 533 .

[0093] The shunt tube 53 serves as an auxiliary pipeline, which can connect the first venous tube 51 and the second venous tube 52. Specifically, when coagulation occurs inside the venous pot body, in order to prevent the thrombosis from blocking the pipeline, the venous pot body needs to be replaced. At this time, the shunt tube 53 can be directly connected to the first venous tube 51 and the second venous tube 52. After the connection, the dialyzed blood can flow into the patient's body through the second venous tube 52, the second catheter 532, the auxiliary pot body 533, the first catheter 531 and the first venous tube 51, so that the hemodialysis process can continue without interruption when the venous pot body is replaced. In addition, a filter layer is provided in the auxiliary pot body 533, which can filter the blood flowing back into the human body to prevent the backflow of blood from being blocked.

[0094] Advantageously, in some embodiments of the present invention, spiral guide holes are provided inside the arterial pot body 22 and the venous pot body.

[0095] In this way, when the blood flows through the arterial pot body 22 and the venous pot body, it can flow in a spiral shape along the spiral guide hole, that is, a rotational flow. Compared with the linear flow, this rotational flow mode makes the blood flow speed close to the rotation center and away from the rotation center different. Therefore, it will cause the blood to vibrate to a certain extent, and thus, to a certain extent, it can prevent blood coagulation.

[0096] Advantageously, in other embodiments of the present invention, the inner wall of the spiral guide hole in the venous pot is coated with a heparin coating.

[0097] Heparin coating has a good anti-coagulation effect. Therefore, applying heparin coating on the venous ampules can play a certain anti-coagulation role when the blood is returned to the human body, thereby preventing the venous ampules from being blocked due to thrombosis.

[0098] Of course, in other embodiments, other drugs that can prevent blood coagulation, such as antiplatelet aggregation drugs, dicoumarol drugs, etc., can also be used to avoid clogging of the pipeline and affecting use.

[0099] Advantageously, in other embodiments of the present invention, the color of the arterial pot body 22 is red, and the color of the venous pot body is blue.

[0100] The arterial and venous pots are in different colors, making it easy for medical staff to distinguish between the two. This makes it easy for medical staff to quickly select and use them, preventing them from making mistakes.

[0101] Advantageously, in some further embodiments of the present invention, there is an electric valve on the first venous tube 51, and a pressure sensor is provided inside the electric valve. The pressure sensor is used to detect the blood pressure in the first venous tube 51 and can adjust the opening and closing degree of the electric valve when the blood pressure value is higher than a preset value.

[0102] In this way, by setting up an electric valve and a pressure sensor, the blood pressure value can be automatically detected, and the opening and closing degree of the valve can be automatically detected and adjusted according to the detected blood pressure value to adjust the blood flow rate. Accordingly, the blood pressure value can also be adjusted to avoid excessively high blood pressure and harm to the patient when the blood is returned to the human body through the first venous tube 51.
