Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis machines, in particular to a flow blocking structure for the pipeline of a hemodialysis machine. Background Technique

[0002] Air embolism refers to a certain amount of air entering the blood vessels, mixing with the blood, and reaching the right heart and pulmonary artery as a foamy body fluid, obstructing blood flow. Air embolism is an acute complication of hemodialysis, which can lead to heart failure. When a large amount of air enters the vein to form an air embolism, it can endanger the life of the patient.

[0003] At the part where there is negative pressure in front of the pump in the pipeline of the hemodialysis machine, air may still enter the blood vessels. Therefore, in the pipeline through which the blood flows, the hemodialysis machine also needs to detect whether there are air bubbles. If air bubbles are detected, the blood with air bubbles should be immediately prevented from returning to the human body.

[0004] Before the existing flow blocking structure is used, it is necessary to fix the pipeline of the hemodialysis machine, and then reset the extrusion component. When flow blocking is required, it is squeezed for flow blocking. However, during each use of the hemodialysis machine, the pipeline needs to be replaced. Therefore, it is necessary to fix the pipeline again and then reset the extrusion component, which is more cumbersome to use. Therefore, this application proposes a flow blocking structure for the pipeline of a hemodialysis machine. Content of the Utility Model

[0007] A flow blocking strip is arranged on the fronts of the fixing plate and the moving plate. The flow blocking strip is connected with an active component, and the active component cooperates with the flow blocking strip to squeeze and block the fixed pipeline of the hemodialysis machine.

[0008] Preferably, the moving component includes:

[0009] The moving rod is movably inserted into the interior of the mounting seat, and the end of the moving rod is connected to the back surface of the moving plate;

Detailed implementation manners

[0025] To better understand the above technical solutions, the following will elaborate on the above technical solutions in combination with the specification drawings and specific implementation manners.

[0026] An embodiment of the present invention discloses a flow blocking structure for the blood dialysis machine line tube. As shown in the attached Figures 1-4 figure, it includes a mounting seat 1 fixedly installed on the front of the blood dialysis machine. A fixing plate 101 is fixedly installed on the front of the mounting seat 1, and a moving plate 102 is slidably connected to the front of the mounting seat 1. A plurality of fixed clamps 103 and a plurality of moving clamps 104 are respectively fixedly installed on the fronts of the fixing plate 101 and the moving plate 102. The plurality of fixed clamps 103 are respectively abutted against the plurality of moving clamps 104. The plurality of moving clamps 104 are connected to a moving component, and the moving component drives the plurality of moving clamps 104 to cooperate with the plurality of fixed clamps 103 to clamp and fix the blood dialysis machine line tube;

[0027] A flow blocking strip 105 is arranged on the fronts of the fixing plate 101 and the moving plate 102. The flow blocking strip 105 is connected to a movable component, and the movable component cooperates with the flow blocking strip 105 to squeeze and block the fixed blood dialysis machine line tube.

[0028] During use, the moving component is used to pull the moving plate 102 outward, causing the moving plate 102 to move away from the fixed plate 101. As a result, the plurality of fixed clips 103 and the plurality of moving clips 104 are separated, and at the same time, the guiding bar 304 moves away from the flow-blocking bar 105. At this time, the blood dialysis machine wire tube is placed between the back of the flow-blocking bar 105 and the plurality of fixed clips 103 and the plurality of moving clips 104. Then, the moving component is used to push the moving plate 102 inward, causing the moving plate 102 to move towards the fixed plate 101. Thus, the blood dialysis machine wire tube is quickly clamped and fixed by the plurality of fixed clips 103 and the plurality of moving clips 104. At the same time, the flow-blocking bar 105 is automatically in place and can perform the flow-blocking operation at any time. When it is necessary to block the blood dialysis machine wire tube, the flow-blocking bar 105 is driven by the moving component to squeeze the fixed blood dialysis machine wire tube to achieve the flow-blocking effect.

[0029] Specifically disclosed, the moving component includes:

[0030] A moving rod 2, which is movably inserted into the interior of the mounting seat 1, and the end of the moving rod 2 is connected to the back surface of the moving plate 102;

[0031] A limiting spring 201, which is fixedly installed between the end of the moving rod 2 and the inner wall of the mounting seat 1.

[0032] Furthermore, a moving groove 202 is formed on the front surface of the mounting seat 1, a moving block 203 is fixedly connected to the inner wall of the moving groove 202, and the moving block 203 is fixedly connected to the end of the moving rod 2 and the back surface of the moving plate 102.

[0033] When the moving rod 2 is pulled outward, it can drive the moving block 203 to slide in the moving groove 202, stretching the limiting spring 201 and causing the moving plate 102 to move accordingly. At this time, the moving plate 102 moves away from the fixed plate 101. When the moving rod 2 is released, under the action of the limiting spring 201, the moving plate 102 can move towards the fixed plate 101 at this time.

[0034] Specifically disclosed, the moving component includes:

[0035] A fixed sleeve 3, which is fixedly installed on the front surface of the mounting seat 1;

[0036] A threaded rod 301, which is rotatably connected to the interior of the fixed sleeve 3. A nut seat 302 is threadedly connected to the outside of the threaded rod 301, and the nut seat 302 is connected to the end of the flow-blocking bar 105.

[0037] Furthermore, an activity groove is formed in the outer side of the fixed sleeve 3, and an activity block 303 is slidably connected to the inner wall of the activity groove. The two ends of the activity block 303 are respectively connected to the nut seat 302 and the end of the flow blocking strip 105.

[0038] When the threaded rod 301 is rotated, since the outer side of the threaded rod 301 is threadedly connected to the nut seat 302, the nut seat 302 can be made to slide inside the fixed sleeve 3, and then the flow blocking strip 105 can be driven to move through the activity block 303.

[0039] Furthermore, a guiding strip 304 is fixedly connected to the front surface of the moving plate 102, and one end of the flow blocking strip 105 away from the activity block 303 is slidably connected to the outer wall of the guiding strip 304.

[0040] By providing the guiding strip 304, on the one hand, it plays a guiding role for the flow blocking strip 105, and on the other hand, it can play a limiting role for the blood dialysis machine wire tube, so that when the flow blocking strip 105 moves, it can play a better role in squeezing and blocking the blood dialysis machine wire tube.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
