Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a safe and efficient autologous blood transfusion device. Background Art

[0002] Since blood shortage has become a serious medical and social problem, and autologous blood transfusion devices can avoid the infection risks that may be brought about by transfusing allogeneic blood, such as infecting hepatitis virus, AIDS virus, etc., and can also reduce the incidence of adverse reactions such as allergic reactions, febrile reactions and immune rejection caused by allogeneic blood. Moreover, in the case of blood source tension, the patient's own blood can be effectively utilized to alleviate the problem of insufficient blood supply, so that the limited blood resources can be used for patients in greater need. Therefore, having a safe and efficient autologous blood transfusion device is a relatively important medical device at present.

[0003] In the patent document with the Chinese patent number CN215230881U that has been published, an autologous blood transfusion device is disclosed, including the main body of the autologous blood transfusion machine. By setting a heating box and a heating block, the blood in the transfusion tube can be heated to avoid the patient having a hypothermia stress reaction due to directly transfusing low-temperature blood; also by setting an installation box, a bidirectional threaded rod and an installation block, the space required for hanging the blood bag can be adjusted to avoid occupying too much operating room space, and the blood bag is fixed by a hanging ring and a limiting ring to prevent collision and falling.

[0004] When the above device is in use, it only uses the heating box and the heating block to heat the blood, ignoring the problem of "erythrocyte washing injury" existing in autologous blood transfusion technology.

[0005] According to the records of existing literature, after the red blood cells washed with normal saline (NS) are incubated for 2 hours, some become acanthocytes, and after being incubated for 48 hours, they become ghost cells. The erythrocyte injury is related to Ca 2+ overload. The hemoglobin is 7.6 g / L lower on the second day after surgery than on the first day after surgery, and the lifespan of the washed red blood cells is shortened within 3 days after transfusion.

[0006] It is indicated that there are varying degrees of erythrocyte washing injury problems in the clinical application of existing autologous blood transfusion technologies. In addition, in clinical practice, if the operator lacks experience or the operation is not standardized in case of emergency such as massive bleeding, the risk of erythrocyte washing injury will be further increased. Therefore, from the perspective of blood protection, while strictly standardizing the autologous blood transfusion operation process, it is necessary to upgrade the existing autologous blood transfusion device technically to reduce the incidence of erythrocyte washing injury and improve the clinical treatment effect.

[0007] Therefore, the present application proposes a safe and efficient autologous blood transfusion device. Summary of the Invention

[0010] The heat preservation component includes a double-layer water bath heat preservation box, and a protective bracket is fixedly installed on the inner wall of the double-layer water bath heat preservation box.

[0011] On the top of the protective bracket, an external gear ring is rotatably installed through an insertion ring. On the side of the protective bracket facing the external gear ring, a main gear component is provided for helping the external gear ring to rotate. A plurality of arc-shaped transmission channels are formed on the surface of the external gear ring. Inside the arc-shaped transmission channels, positioning insertion rods are slidably installed. One end of the positioning insertion rod passing through the external gear ring is slidably installed with a vertical transmission frame. An external heat preservation pipe is fixedly installed inside the vertical transmission frame. On the top of the positioning insertion rod, a ultrasonic conduction component is slidably installed. On the top of the positioning insertion rod, a protective plate is fixedly installed. A spring is fixedly installed between the protective plate and the ultrasonic conduction component.

[0012] Optionally, the transport vehicle component includes an external frame, a bearing frame is fixedly installed at the bottom of the external frame, and a sealing cover is hinged on one side of the external frame.

[0013] Optionally, a first lifting component is fixedly installed on one side of the external frame, a second lifting component is fixedly installed on the other side of the external frame, and a control terminal is fixedly installed on the top of the external frame.

[0014] Optionally, the inside of the double-layer water bath heat preservation box is a cavity. A water pump is fixedly installed on one side of the double-layer water bath heat preservation box, and a fixed bracket is fixedly installed on the outside of the double-layer water bath heat preservation box, and the fixed bracket is fixedly installed on the inner wall of the external frame.

[0015] Optionally, the filtering component includes a first transmission pipe fixedly installed on the top of the double-layer water bath heat preservation box, a second transmission pipe is rotatably installed at the bottom of the double-layer water bath heat preservation box, the second transmission pipe and the first transmission pipe are arranged in a communicating state, and a third transmission pipe is rotatably installed at the bottom of the second transmission pipe.

[0016] Optionally, a second gear is rotatably installed inside the external heat preservation pipe, a first gear is fixedly installed on the outer side of the second transmission pipe, the second gear and the first gear are arranged in a meshing state, the second transmission pipe is rotatably installed inside the external heat preservation pipe, a limiting insertion ring is fixedly installed at the top of the third transmission pipe, and the limiting insertion ring is slidably installed inside the second transmission pipe.

[0017] Optionally, a plurality of second conduction teeth are fixedly installed inside the second transmission pipe, a plurality of first conduction teeth are fixedly installed at the top of the third transmission pipe, and an arc-shaped conduit is fixedly installed on one side of the second transmission pipe where the second transmission pipe is located relative to the third transmission pipe.

[0018] Optionally, a filter screen is fixedly installed inside the third transmission pipe, a plurality of positioning blocks are fixedly installed on the outer side of the third transmission pipe, the third transmission pipe is slidably installed on the inner wall of the external heat preservation pipe through the plurality of positioning blocks, and auxiliary springs are fixedly installed on the upper and lower sides of the positioning blocks.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The washing assembly is used to receive the anticoagulated and filtered blood, and under the action of the ultrasonic intervention assembly, low-intensity pulsed ultrasound is used to wash and protect red blood cells, and then the blood is transmitted through the return pipe for recycling. Thus, under the protection of low-intensity pulsed ultrasound for washing red blood cells, the washing damage of red blood cells is reduced.

[0021] 2. As the positioning insertion rod continuously pushes the ultrasonic conduction assembly to extrude the external heat preservation pipe outwards, the ultrasonic conduction assembly generates a greater reaction force through the spring connected to the protection plate, thereby enhancing the fixing effect of the protection plate on the external heat preservation pipe. This design not only effectively reduces the damage of red blood cells during washing through low-intensity pulsed ultrasound, but also significantly improves the stability during blood transmission.

[0022] 3. The third transmission pipe vertically slides along the sliding hole of the external heat preservation pipe through the positioning blocks, causing the filter screen to be in a state of shaking up and down. Furthermore, the residues and some particulate matters in the blood during the operation are separated by the filter screen while being in a shaking state, so that the filter screen will not be blocked, thereby ensuring the normal flow of blood. And because the blood is pushed back and forth by the third transmission pipe to generate a back-and-forth pushing amplitude, the blood cells are in an active state, better cooperating with the ultrasonic intervention assembly to perform low-intensity pulsed ultrasound protection on the red blood cells piled up together.

Detailed implementation manners

[0042] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] A safe and efficient autologous blood transfusion device proposed by the present invention includes a transport vehicle assembly 1. A heat preservation assembly 2 is installed inside the transport vehicle assembly 1. A filtering assembly 4 is installed inside the heat preservation assembly 2. An anticoagulant transmission assembly 3 is fixedly installed on one side of the filtering assembly 4, as Figure 2, the anticoagulant delivery assembly 3 includes a storage tank and a delivery pipe. The storage tank contains anticoagulants, which can be heparin and ACD-A (citric acid - sodium citrate - dextrose solution). The anticoagulants are delivered into the first delivery pipe 401 using the delivery pipe. The heparin concentration is generally 30,000 U / L. During blood recovery, the anticoagulants are delivered into the first delivery pipe 401 using the delivery pipe, and the flow rate is controlled so that the blood loss and the heparin solution reach a certain ratio, such as adding 15 mL of heparin solution to 100 mL of blood loss, with a rough ratio of 7:1. A washing assembly 5 is installed at the bottom of the filtration assembly 4, and the washing assembly 5 is fixedly installed at the bottom of the heat preservation assembly 2. A return pipe 6 is fixedly installed at the top of the washing assembly 5. Ultrasonic intervention assemblies 7 are installed on the outer sides of both the filtration assembly 4 and the return pipe 6. During autologous blood transfusion, Piezo1 is a mechanically activated ion channel that is widely expressed on the surface of red blood cell membranes. Under the action of mechanical force, Piezo1 can cause Ca 2+ influx, regulate the morphology of red blood cells, and cause damage to red blood cells. The ultrasonic intervention assembly 7 reduces red blood cell washing damage by emitting low-intensity pulsed ultrasound to act on red blood cell Piezo1. As shown in Figure 3 , the washing assembly 5 is used to receive the blood after anticoagulation and filtration, and under the action of the ultrasonic intervention assembly 7, the red blood cells are protected by washing with low-intensity pulsed ultrasound, and then the blood is transmitted through the return pipe 6 for recycling.

[0044] As shown in Figures 10 - 12 , the experimental data show that after autologous blood is recovered and washed, the Ca 2+ concentration, reactive oxygen species (ROS) level, and Piezo1 protein expression in red blood cells incubated in plasma for 24 h and 72 h are all significantly upregulated, suggesting that there is a certain degree of red blood cell damage during autologous blood washing and transfusion. Compared with Con, ** P < 0.01, **** P < 0.0001, n = 4 ( * indicating statistical significance and reflecting the degree of difference from the Con group);

[0045] As shown in Figures 13 - 15 , the experimental data show that low-intensity pulsed ultrasound intervention can reduce the upregulation of Ca 2+ concentration, ROS level, and Piezo1 protein expression in red blood cells recovered and washed from autologous blood, suggesting that ultrasound intervention can effectively reduce red blood cell damage during autologous blood recovery and washing. Compared with Con, ** P < 0.01, *** P < 0.001; compared with IBS, # P < 0.05, ## P < 0.01, #### P < 0.0001, n = 4 ( #Indicates statistical significance and reflects the degree of difference from the IBS group). Among them, IBS represents the autologous blood recovery step, US represents the ultrasound intervention step, and IBS+US represents the combined implementation of the autologous blood recovery and ultrasound intervention steps.

[0046] As Figures 16 - 18 shown, the experimental data indicate that the Piezo1 receptor agonist Yoda1 can significantly reverse the inhibitory effects of low-intensity pulsed ultrasound on the Ca 2+ concentration, reactive oxygen species (ROS) level, and upregulation of Piezo1 expression, suggesting that the protective effect of ultrasound intervention is blocked by Yoda1, indicating that ultrasound stimulation targets the Piezo1 protein to exert a protective effect on red blood cells. Compared with Con, **** P < 0.0001; compared with IBS, # P < 0.05, ### P < 0.001; compared with IBS+US, && P < 0.01, &&& P < 0.001, n = 4 ( & Indicates statistical significance and reflects the degree of difference from the IBS+US group). Among them, Yoda1 is an agonist of Piezo1.

[0047] As Figures 1 - 2 shown, the transport vehicle assembly 1 includes an external frame 101. A carrier frame 102 is fixedly installed at the bottom of the external frame 101. A sealing cover 103 is hinged to one side of the external frame 101. A first lifting assembly 104 is fixedly installed on one side of the external frame 101. A second lifting assembly 105 is fixedly installed on the other side of the external frame 101. A control terminal 106 is fixedly installed at the top of the external frame 101. Medical staff can install different medical components through the second lifting assembly 105 and the first lifting assembly 104. The inside of the double-layer water bath incubator 201 is a cavity. A water pump is fixedly installed on one side of the double-layer water bath incubator 201. A fixing bracket 202 is fixedly installed on the outside of the double-layer water bath incubator 201, and the fixing bracket 202 is fixedly installed on the inner wall of the external frame 101. The water flow circulates inside the double-layer water bath incubator 201 through the water pump, and there is a temperature control component inside the double-layer water bath incubator 201, so that the blood can be kept warm during anticoagulation, filtration, etc. operations. And because the double-layer water bath incubator 201 is double-layer, the inner layer is a heat preservation layer, so that the water flow can have a longer heat preservation effect and improve the blood transfusion effect.

[0048] As Figures 3 - 7As shown, the filtering component 4 includes a first transmission pipe 401 fixedly installed on the top of the double-layer water bath incubator 201. A second transmission pipe 404 is rotatably installed at the bottom of the double-layer water bath incubator 201. The second transmission pipe 404 is communicatively connected to the first transmission pipe 401. A third transmission pipe 408 is rotatably installed at the bottom of the second transmission pipe 404. A second gear 409 is rotatably installed inside the external heat preservation pipe 403. A first gear 405 is fixedly installed on the outer side of the second transmission pipe 404. The second gear 409 is in a meshing state with the first gear 405. The second transmission pipe 404 is rotatably installed inside the external heat preservation pipe 403. A limit insertion ring 406 is fixedly installed at the top of the third transmission pipe 408. The limit insertion ring 406 is slidably installed inside the second transmission pipe 404. A plurality of second conduction teeth 413 are fixedly installed inside the second transmission pipe 404. A plurality of first conduction teeth 407 are fixedly installed at the top of the third transmission pipe 408. An arc-shaped conduit 410 is fixedly installed on one side of the second transmission pipe 404 where the second transmission pipe 404 is located relative to the third transmission pipe 408. The arc-shaped conduit 410 extends into the third transmission pipe 408, so that when the third transmission pipe 408 slides, the two are still in a sealed state. A filter screen 411 is fixedly installed inside the third transmission pipe 408. A plurality of positioning blocks 412 are fixedly installed on the outer side of the third transmission pipe 408. The third transmission pipe 408 is slidably installed on the inner wall of the external heat preservation pipe 403 through the plurality of positioning blocks 412. Auxiliary springs 402 are fixedly installed on the upper and lower sides of the positioning blocks 412. During the process of blood being transmitted from the first transmission pipe 401 into the second transmission pipe 404, the motor inside the external heat preservation pipe 403 drives the second gear 409 to rotate. The second gear 409 drives the second transmission pipe 404 to rotate along the connection between the double-layer water bath incubator 201 and the third transmission pipe 408. At this time, the second conduction teeth 413 rotate together with the second transmission pipe 404, while the first conduction teeth 407 remain stationary. Since the first conduction teeth 407 are in a wave shape, when the second conduction teeth 413 rotate to the convex part of the first conduction teeth 407, the third transmission pipe 408 is squeezed. The third transmission pipe 408 drives the limit insertion ring 406 to move downward along the chute between the third transmission pipe 408 and the second transmission pipe 404. Due to gravity guidance and the blood flow direction, and as Figure 6 , the second transmission pipe 404 and the third transmission pipe 408 are still in a sealed state, so that blood will not seep out. The third transmission pipe 408 vertically slides along the sliding hole of the external heat preservation pipe 403 through the positioning blocks 412, so that the filter screen 411 is in a state of shaking up and down. Then, the residues and some particulate matters in the blood during the operation are separated by the filter screen 411 while being in a shaking state, so that the filter screen 411 will not be blocked, thus ensuring the normal flow of blood. And because the blood is pushed back and forth by the third transmission pipe 408 to generate a back-and-forth pushing amplitude, the blood cells are in an active state, which better cooperates with the ultrasonic intervention component 7 to perform low-intensity pulsed ultrasound protection on the red blood cells piled up together.

[0049] In this embodiment, as Figure 8 shown, the heat preservation assembly 2 includes a double-layer water bath heat preservation box 201. A protective bracket 701 is fixedly installed on the inner wall of the double-layer water bath heat preservation box 201. An external gear ring 703 is rotatably installed on the top of the protective bracket 701 through an insertion ring 702. A main gear assembly is arranged on one side of the protective bracket 701 facing the external gear ring 703 for driving the external gear ring 703 to rotate. A plurality of arc-shaped transmission channels 704 are formed on the surface of the external gear ring 703. A positioning insertion rod 706 is slidably installed inside the arc-shaped transmission channel 704. One end of the positioning insertion rod 706 passing through the external gear ring 703 is slidably connected to a vertical transmission frame 705. An external heat preservation pipe 403 is fixedly installed inside the vertical transmission frame 705. An ultrasonic conduction assembly 707 is slidably installed on the top of the positioning insertion rod 706, and a protective plate 708 is fixedly installed on its top. A spring is fixedly installed between the protective plate 708 and the ultrasonic conduction assembly 707. When the ultrasonic conduction assembly 707 applies low-intensity pulsed ultrasound to the blood inside the third transmission pipe 408, the motor on the side of the protective bracket 701 drives the main gear assembly to rotate. The main gear assembly meshes with the external gear ring 703 to drive the external gear ring 703 to rotate. Since the arc-shaped transmission channel 704 is arc-shaped, when the external gear ring 703 rotates, the positioning insertion rod 706 moves along the vertical transmission frame 705 under the push of the arc-shaped transmission channel 704, thereby driving the protective plate 708 and the ultrasonic conduction assembly 707 to approach the external heat preservation pipe 403. Continuous or strong vibration may affect the connection parts of the blood transmission pipeline, resulting in loose connection or blood leakage. Especially for some pipelines with plug-in or ferrule connections, vibration may reduce the friction between the connection parts and lower the connection stability. Therefore, the ultrasonic conduction assembly 707 fits and clamps the external heat preservation pipe 403 to reduce its vibration, thereby reducing the vibration amplitude of the internal components of the external heat preservation pipe 403. As the positioning insertion rod 706 continues to slide, the ultrasonic conduction assembly 707 fits on the outer side of the external heat preservation pipe 403, and the protective plate 708 slides along the positioning insertion rod 706 to the outer side of the ultrasonic conduction assembly 707. The protective plate 708 generates a greater thrust on the outer side of the ultrasonic conduction assembly 707 through the spring connected to the ultrasonic conduction assembly 707, further enhancing the fixing effect of the protective plate 708 on the external heat preservation pipe 403, thereby reducing the washing damage of red blood cells by using low-intensity pulsed ultrasound and improving the stability during blood transmission at the same time;

[0050] It should be noted here that compared with the traditional ultrasonic component, the surface of the ultrasonic conduction assembly 707 facing the focusing probe is designed as a concave surface to achieve precise focusing of ultrasonic energy. At the same time, as Figure 9As shown, the distance from the external heat-insulating pipe 403 to the blood is the attenuation distance of the ultrasonic intensity caused by the pipe wall (the specific attenuation distance is related to the printing preparation). Since multiple groups of focus-focusing probes are arranged along both the X-axis and the Y-axis of the ultrasonic conduction component 707, and the ultrasonic conduction component 707 is arc-shaped and can wrap around the circumferential side of the external heat-insulating pipe 403 or the return pipe 6, multiple focus-focusing probes can be aligned with the blood in the external heat-insulating pipe 403 or the return pipe 6 to intervene in the blood before entering the washing component 5 for washing and after washing and being transported back into the return pipe 6, improving the intervention effect. Multiple foci form an arc that coincides with the external heat-insulating pipe 403 and the return pipe 6. As Figure 9 shown in the shaded area in, the arc-shaped foci fully wrap the red blood cells in the blood, ensuring sufficient intervention in the red blood cells with irregular arrangement along the X-axis. At the same time, since the ultrasonic conduction component 707 is relatively long, during the flow of the blood, the red blood cells have sufficient time to receive ultrasonic intervention along the Y-axis, thereby further improving the efficiency of low-intensity pulsed ultrasound.

[0051] This solution has carried out systematic integration and optimization in the process of autologous blood transfusion, covering a series of key processing steps such as blood collection, anticoagulation, filtration, washing, and concentration. Compared with traditional blood transfusion methods or simple blood collection and treatment, this is a relatively comprehensive and in-depth technical improvement, enabling autologous blood to be transfused into the patient's body more safely and effectively, providing more reliable blood support for patients during surgery, and improving the safety and success rate of surgery.

[0052] In clinical applications, for surgeries with large blood loss such as cardiac surgery, orthopedic orthopedics, and emergency massive bleeding, etc., this device can timely and effectively solve the blood supply problem. By avoiding the risks that may be brought about by insufficient allogeneic blood supply or adverse reactions to allogeneic blood transfusion, this device has important application value in clinical practice. This device not only meets the needs in specific medical scenarios, but also provides important supplementation and improvement to existing medical technologies, further optimizing the blood protection strategy during surgery and improving the surgical safety and the prognosis of patients.
