Description

Technical Field

[0001] The utility model relates to the technical field of circulation pipelines, in particular to an extracorporeal circulation pipeline. Background Art

[0002] A circulation pipeline refers to a series of pipeline systems used to maintain extracorporeal circulation. It is used in situations such as cardiac surgery and extracorporeal membrane oxygenation. The blood is drawn out of the body, processed through oxygenation, filtration, etc., and then transported back into the body to maintain the circulatory function of the body.

[0003] During the use of traditional extracorporeal circulation pipelines, most of them only have a single arterial pot and a venous pot. Thrombus is likely to form in these two places, causing congestion. Once one of them is blocked, it is necessary to cut off the blood circulation pipeline with a clamp from the pipelines on both sides of the pot, then disassemble and screw off the corresponding pot, and reinstall a new pot. This process will affect the hemodialysis of hemodialysis patients, which is rather troublesome and makes the entire circulatory system less reliable. Therefore, we propose an extracorporeal circulation pipeline to solve the problems mentioned above. Content of the Utility Model

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1-5 shown, the extracorporeal circulation pipeline includes an overall structure 1 and an auxiliary structure 2, and the auxiliary structure 2 is located at the center of the front outer surface of the overall structure 1; the overall structure 1 includes a box body 101, connecting rods 103 are fixedly connected to the front and rear positions of the inner surfaces on both sides of the box body 101, a dialysis machine body 104 is fixedly connected to the opposite sides of the two connecting rods 103, kettle bodies 102 are slidably connected to the top and bottom sides of the dialysis machine body 104, a connector 108 is fixedly connected to the inner surface of the connecting rod 103, a sliding rod 113 is fixedly installed on the outer surface of the connector 108, a splint 109 is fixedly connected to the extending end of the sliding rod 113, and a compression spring 114 is sleeved on the outer surface of the sliding rod 113.

[0025] The effect achieved by the entire Embodiment 1 is, as Figure 2As shown, the bottoms and tops of the two connectors 108 are fixedly connected to the top and bottom of the dialysis machine body 104, enabling stable subsequent use. During actual use, the sealing ring 107 is inside the kettle body 102, and the connecting hose 106 is docked with the kettle body 102. The setting of the sealing ring 107 can increase the sealing performance at the connection between the connecting hose 106 and the kettle body 102, preventing leakage. When the clamping plate 109 limits the connecting hose 106, it also utilizes the expansion force of the compression spring 114 and the force of screwing in the first bolt 111, enabling the anti-slip pad 112 and the clamping plate 109 to fit more closely to the outer surfaces of the connecting hose 106 and the kettle body 102, as Figure 1 and Figure 2 shown, placing the dialysis machine body 104 inside the box body 101 can play a protective role, preventing damage from external collisions. And as Figure 1 shown, there are two round holes on the transparent baffle 201, which can ensure the air circulation inside the box body 101.

[0026] Example 2, as Figures 1-5 shown, heating plates 105 are fixedly installed at the centers of the inner surfaces on both sides of the box body 101. One end of the compression spring 114 is fixedly connected to the outer surface of the clamping plate 109, and the other end of the compression spring 114 is fixedly connected to the outer surface of the connector 108. The connecting hose 106 passes through the top and bottom of the inner surfaces on both sides of the box body 101. The center of the bottom of the connecting hose 106 is fixedly connected with a sealing ring 107. The outer surfaces of the connecting hose 106 and the sealing ring 107 are slidably connected to the inner surface of the kettle body 102. The inner surface of the clamping plate 109 is fixedly connected with an anti-slip pad 112. The outer surfaces of the anti-slip pad 112 and the clamping plate 109 are slidably connected to the outer surfaces of the kettle body 102 and the connecting hose 106. The first bolt 111 is threadedly penetrated through the front and rear positions of the outer surface of the clamping plate 109. A threaded hole 110 is provided at the position of the clamping plate 109 on the outer surface of the clamping plate 109. The connecting pipes 115 penetrate through the top and bottom of the outer surface on both sides of the front side of the dialysis machine body 104. The second bolts 116 are threadedly penetrated through the positions on both sides of the front side outer surface of the connecting pipes 115. The rear end face of the second bolt 116 threadedly penetrates through the outer surface of the kettle body 102. The inner wall of the threaded hole 110 is threadedly connected to the outer surface of the first bolt 111. The auxiliary structure 2 includes a transparent baffle 201, and a handle 202 is fixedly connected to the center of one side of the front side outer surface of the transparent baffle 201.

[0027] The overall effect achieved by the entire Example 2 is that through the setting of the anti-slip pad 112, the friction with the connecting hose 106 can be increased. Then, through the force of screwing in the first bolt 111, the clamping plate 109 can more stably clamp and fix the connecting hose 106, ensuring that the connecting hose 106 will not fall off. During actual use, asFigure 2 As shown, there are multiple pots 102 provided on the dialysis machine body 104. The pot 102 located at the top is the arterial pot, and the pot 102 located at the bottom is the venous pot. By setting multiple pots 102, a dual-channel pot 102 extracorporeal circulation pipeline can be achieved. Through the setting of the transparent baffle 201 and the handle 202, it is convenient for the user to check the working conditions inside the box body 101 at any time.

[0028] Working principle: When in use, the user can place multiple pots 102 on the dialysis machine body 104, and then the user puts the connecting hose 106 into the corresponding pot 102, so that the sealing ring 107 can enter the pot 102. Then, through the mutual cooperation of the sliding rod 113, the compression spring 114, the clamping plate 109 and the anti-slip pad 112, the clamping plate 109 can utilize the expansion force of the compression spring 114 to initially limit and fix the connecting hose 106. Then the user screws the first bolt 111 into the corresponding threaded hole 110. Then the clamping plate 109 and the anti-slip pad 112 can utilize the screwing force to make them fit more tightly against the outer surfaces of the connecting hose 106 and the pot 102, avoiding the separation of the connecting hose 106, and thus completing the overall installation. The disassembly can be achieved by reversing the above steps. And as Figure 2 As shown, multiple pots 102 are arranged in the box body 101, which can achieve dual-channel pot 102 extracorporeal circulation management. If a thrombus blockage occurs in a certain pot 102 later, the corresponding pot 102 can be removed without affecting the hemodialysis operation of the other pots 102. For the separation of the dialysis machine body 104 and the pot 102, the user can unscrew the corresponding second bolt 116, and then the connecting pipe 115 can be separated from the corresponding pot 102.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
