[0034] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.
[0035] Example
[0036] like Figure 1-6 As shown, this embodiment provides a venous clamp structure, which includes a shell, a rotating shaft clamp 300 and a controller, the shell includes an upper shell 100 and a lower shell 200 that are unilaterally rotatably connected, a fitting surface is formed between the upper shell 100 and the lower shell 200, the lower surface of the upper shell 100 and the upper surface of the lower shell 200 are respectively provided with an upper groove 110 and a lower groove 210 that match the venous blood tube; the rotating shaft clamp 300 is arranged next to the lower groove 210, and after the rotating shaft clamp 300 is rotated, it blocks the passage of the venous blood tube placed in the lower groove 210; it also includes an ultrasonic sensor, which is arranged in the upper groove 110 and the lower groove 210, and is used to monitor bubbles in the venous blood tube and send instructions to the controller, the blood discriminator 500 is arranged on both sides of the upper groove 110, and is used to determine that the liquid transported in the venous blood tube is blood, and the controller controls the rotation of the rotating shaft clamp 300.
[0037] In this embodiment, the left side of the upper shell 100 and the left side of the lower shell 200 are connected by a rotating shaft to form an openable and closable door. The upper shell 100 is composed of an inner shell and an outer shell to form a rectangular cavity, and the ultrasonic sensor is placed in the cavity; the lower shell 200 cooperates with the upper shell 100 to form a fitting surface after closing; the lower surface of the upper shell 100 is provided with an upper groove 110, and the upper surface of the lower shell 200 is provided with a lower groove 210, and the upper groove 110 and the lower groove 210 are used to place a venous blood tube.
[0038] In this embodiment, the wires of the ultrasonic sensor pass through the rotating shaft to avoid setting a separate routing position for the wires of the ultrasonic sensor, reducing the installation process, improving installation efficiency, and also avoiding contact between the wires and the venous blood line, thereby affecting safety of use.
[0039] In this embodiment, the rotating shaft clamp 300 is arranged next to the lower groove 210. When the rotating shaft clamp 300 is driven to rotate by the driving shaft 410, the venous blood tube placed in the upper groove 110 and the lower groove 210 is clamped to block the blood flow; when the rotating shaft clamp 300 is reset to the initial state, the venous blood tube placed in the upper groove 110 and the lower groove 210 resumes verticality and blood continues to flow.
[0040] In this embodiment, the ultrasonic sensor is arranged in the upper groove 110 and the lower groove 210, and is arranged around the front and back of the venous blood tube for monitoring bubbles. When bubbles appear in the venous blood tube, the ultrasonic sensor senses it and transmits a signal to the controller, and the controller drives the drive shaft 410 to rotate by electromagnetic means, and the drive shaft 410 drives the rotating shaft clamp 300 to rotate, so that the venous blood tube is clamped to block the passage; when the bubbles in the venous blood tube are cleared, the ultrasonic sensor detects it and sends a signal to the controller, and the controller drives the drive shaft 410 to reset by electromagnetic means, and the drive shaft 410 drives the rotating shaft clamp 300 to reset, so that the venous blood tube is restored to its original state and the blood in the tube passes normally.
[0041] In this embodiment, the blood discriminator 500 is disposed on both sides of the upper groove 110. When the liquid passing through the venous blood line is red, the blood discriminator 500 determines that blood is flowing in the venous blood line and sends a signal to the controller. When either the ultrasonic sensor or the blood discriminator 500 sends a signal to the controller, the controller can control the electromagnetic drive to rotate the drive shaft 410, and the drive shaft 410 drives the rotating shaft clamp 300 to rotate, so that the venous blood line is clamped to a state of blocking passage.
[0042] The lower shell 200 includes an upper surface and a lower edge extending downward, and the lower groove 210 runs through the upper surface of the lower shell 200 and is parallel to the long side of the lower shell 200; the upper shell 100 includes an upper surface, a lower surface and an upper edge connected between the upper surface and the lower surface, and the upper groove 110 runs through the lower surface of the upper shell 100 and is parallel to the long side of the upper shell 100, and the upper groove 110 includes a movable recess 130 for reserving movable space for the controller and the hinge clamp 300.
[0043] In this embodiment, the lower shell 200 is in the shape of a rectangular base, and the lower shell 200 includes an upper surface and a lower edge. When the venous blood tube is placed in the lower groove 210, it passes through the lower shell 200 in the vertical direction and extends out; the upper shell 100 is in the shape of a rectangular cavity, and the upper shell 100 includes an upper surface, a lower surface and an upper edge. When the venous blood tube is placed in the upper groove 110, it passes through the upper shell 100 in the vertical direction and extends out; the upper groove 110 is parallel to the long side of the upper shell 100, and the lower groove 210 is parallel to the long side of the lower shell 200, which restricts the venous blood tube from passing along the long side parallel to the shell, making it easy to locate the ultrasonic sensor in a horizontal position to improve the accuracy of bubble monitoring.
[0044] In this embodiment, the movable recess 130 and the upper groove 110 are connected. When the upper shell 100 and the lower shell 200 are closed, the pivot clamp 300 does not affect the closure of the upper shell 100 and the lower shell 200 whether it is in a rotating state or restored to its original state. At the same time, the pivot clamp 300 is protected in the movable recess 130 to avoid collision.
[0045] The shell further includes a buckling member 120 disposed on the upper edge and a buckling column 220 disposed on the lower edge. After buckling, the lower surface of the upper shell 100 and the upper surface of the lower shell 200 are in contact with each other.
[0046] In this embodiment, the buckling member 120 is a buckling door with a spring. When the buckling member 120 and the buckling column 220 are buckled, the upper shell 100 and the lower shell 200 are completely fitted.
[0047] The upper groove 110 includes an upper clamping portion, and the lower groove 210 includes a lower clamping portion. The pipe diameter formed by the upper clamping portion and the lower clamping portion is smaller than the pipe diameter formed by the upper groove 110 and the lower groove 210 .
[0048] In this embodiment, an upper clamping portion is provided in the upper groove 100, and a lower clamping portion is provided in the lower groove 210. When the upper shell 100 and the lower shell 200 are closed, since the tube diameter formed by the upper clamping portion and the lower clamping portion is smaller than the tube diameter formed by the upper groove 110 and the lower groove 210, the venous blood tube is squeezed after being clamped, thereby preventing it from sliding in the upper groove 110 and the lower groove 210, which affects the safety of use.
[0049] The rotating shaft clamp 300 includes a plane and an arc surface, the plane contacts the venous blood line tube, the arc surface is aligned with the end surface of the driving shaft, and the length of the long side of the plane is greater than the width of the lower groove 210.
[0050] In this embodiment, the rotating shaft clamp 300 includes a plane and an arc surface, and the side surface of the rotating shaft clamp is connected between the plane and the arc surface. The side surface has two sides, one is parallel to the upper surface of the lower shell 200, and the other is vertically connected to the driving shaft 410. The plane of the rotating shaft clamp 300 is used to directly contact the venous blood tube and squeeze the venous blood tube. The arc surface of the rotating shaft clamp 300 is used to align the driving shaft 410 and move synchronously with the driving shaft 410; when the rotating shaft clamp 300 rotates, the long side of the plane gradually forms an angle with the lower groove 210. Since the length of the long side of the plane is greater than the width of the lower groove 210, the venous blood tube is completely clamped off and passed within the range of less than 90°; when the rotating shaft clamp 300 is reset, since the angle is less than 90°, the reset time of the rotating shaft clamp 300 is shorter and the reset is more flexible.
[0051] The rotating shaft clamp 300 is provided with a reserved hole 310 , and the reserved hole 310 is used for clamping a mechanical tool to manually rotate or reset the rotating shaft clamp 300 .
[0052] In this embodiment, when the reserved hole 310 is in use, the reserved hole 310 on the rotating shaft clamp 300 is used to clip mechanical tools, so that medical staff can manually control the rotation or resetting of the rotating shaft clamp 300 during power outages or other emergency situations; when the reserved hole 310 is not in use, it is not connected to any mechanical tool.
[0053] The controller includes an electromagnet 420 and a driving shaft 410. The electromagnet 420 is disposed under the lower shell 200. The driving shaft 410 is disposed in the electromagnet 420 and connected to the rotating shaft clamp 300. The electromagnet 420 receives instructions from the ultrasonic sensor and drives the driving shaft 410 to rotate. The driving shaft 410 drives the rotating shaft clamp 300 to rotate.
[0054] In this embodiment, the electromagnet 420 is connected to the lower shell 200 through a bracket. When the ultrasonic sensor detects bubbles in the venous blood line, it sends a command to the electromagnet 420. The electromagnet 420 receives a signal through the main control board and sends a command to drive the drive shaft 410 to rotate. After the drive shaft 410 rotates, it drives the rotating shaft clamp 300 to rotate. When the ultrasonic sensor detects that the bubbles in the venous blood line disappear, the electromagnet 420 receives a signal from the ultrasonic sensor in the operating room through the main control board and transmits the signal to the drive shaft 410, so that the rotating shaft clamp 300 is reset.
[0055] The controller further includes a heat sink 430 and a heat insulation pad 440 . The heat sink 430 is disposed on the electromagnet 420 , and the heat insulation pad 440 is disposed between the driving shaft 410 and the rotating shaft clamp 300 .
[0056] In this embodiment, the radiator 430 is a plurality of heat dissipation fins. When the electromagnet 420 generates heat, the heat is conducted to the plurality of heat dissipation fins. The plurality of heat dissipation fins increase the heat conduction area, so that the heat is quickly transferred to the air, thereby preventing heat from accumulating in the electromagnet 420 and being conducted to the drive shaft 410; the thermal insulation pad 440 is arranged between the drive shaft 410 and the rotating shaft clamp 300, so that the heat that is not conducted through the radiator 430 in time is blocked in the thermal insulation pad 440, further protecting the rotating shaft clamp 300 from the influence of heat, thereby affecting the blood temperature in the pipeline when the rotating shaft clamp 300 is in direct contact with the venous blood line, thereby avoiding safety accidents.
[0057] The controller further includes a switch key 450 disposed on the upper surface of the lower shell 200 . The switch key 450 is connected to the driving shaft 410 and is used to control the resetting of the rotating shaft clamp 300 .
[0058] In this embodiment, the switch key 450 is disposed on the upper surface of the lower shell 200 , and the switch key 450 is connected to the electromagnet 420 . When the drive shaft 410 fails and cannot rotate automatically, medical staff can rotate or reset the rotating shaft clamp 300 through the switch key 450 .
[0059] A hemodialysis device provided with a venous clamp structure comprises a dialysis component and a dialysis pipeline, wherein the venous clamp structure and a display screen are also included, wherein the display screen is used to display the use status of the venous clamp structure, the dialysis component and the dialysis pipeline.
[0060] In this embodiment, the display screen not only displays whether the use status of the ultrasonic sensor is normal, but also displays whether the whole machine is running normally. The display screen is an alarm display screen, which is independently connected to the venous clamp structure. Medical staff can observe the status of the ultrasonic sensor in the closed shell through the display screen, so as to timely discover and deal with abnormalities of the ultrasonic sensor.
