Description

Technical Field

[0001] The utility model relates to a tube clamping device and relates to the technical field of heparin tube assembly. Background Art

[0002] During dialysis, in order to prevent coagulation caused by platelet thrombosis and red thrombosis and ensure the safe and smooth progress of blood purification treatment, heparin needs to be injected to provide anticoagulation guarantee for extracorporeal blood circulation. The heparin tube is a tube connecting the blood circuit and the heparin injection device. Before the priming process and 15-60 minutes before the end of dialysis, the heparin tube is closed with a tube clamp.

[0003] As an accessory on the heparin tube, the tube clamp needs to be assembled with a tube clamp device to pass the tube clamp through the heparin tube. However, the existing tube clamp device has a clamping jaw that directly clamps the edge of the tube clamp and cannot maintain the gap between the tube clamps. When the left and right clamps clamp and drive the tube clamp through the tube, the tube clamp will rebound and the gap between the tube clamps will become smaller due to the forward and backward movement of the tube clamp, making it impossible for the heparin tube to pass through the tube clamp, which ultimately leads to the failure of the tube clamp to pass through the tube. Utility Model Content

[0004] The utility model provides a tube clamping device, which ensures that a heparin tube passes through the tube clamp smoothly by increasing the tube clamp gap.

[0007] Preferably, the protrusion is in the shape of an inverted triangle, and the three sharp corners of the protrusion abut against the opening and bottom of the second chamber to expand and increase the opening space of the second chamber.

[0008] Preferably, the protrusion is in a quadrilateral shape, and the four sharp corners of the protrusion abut against the opening and bottom of the second chamber to expand and increase the opening space of the second chamber.

[0019] The embodiments of the present utility model will be further described below with reference to the drawings.

[0020] Embodiment 1

[0021] As Figures 1 to 4 shown, a pipe clamp clamping device includes a left clamping jaw 1 and a right clamping jaw 6 arranged oppositely. The inner vertical surfaces of the left clamping jaw 1 and the right clamping jaw 6 clamp the left and right end faces of the pipe clamp 2. The left clamping jaw 1 and the right clamping jaw 6 are connected to a cylinder 5 arranged above for driving the left clamping jaw 1 and the right clamping jaw 6 to open or close. Protrusions 7 are respectively and correspondingly provided on the inner vertical surfaces of the left clamping jaw 1 and the right clamping jaw 6, and the protrusions 7 are all corresponding to the positions of the second chamber 8 on the pipe clamp 2. When the protrusions 7 slide into the second chamber 8, the gap of the second chamber 8 is enlarged, and the piercing needle 3 passes through the pipe holes on the front and back sides of the pipe clamp 2 and penetrates the pipe clamp 2.

[0022] The protrusion 7 is in an inverted triangular shape, and the three pointed corners of the protrusion 7 abut against the opening and the bottom position of the second chamber 8, for expanding and increasing the opening space of the second chamber 8.

[0023] Each triangular point of the protrusion 7 is respectively provided with a transition slope 12.

[0024] The pipe clamp 2 is placed in the groove 9 on the base 4, and fixing columns 10 are arranged on both sides of the groove 9, and the fixing columns 10 on both sides are used to straighten the pipe clamp 2.

[0025] At least one side of the inner vertical surfaces of the left clamping jaw 1 and the right clamping jaw 6 is provided with an inclined surface 11, and the inclined surface 11 is located above the protrusion 7 for stabilizing the upper end part at the opening of the second chamber 8.

[0026] Embodiment 2

[0027] A pipe clamp clamping device includes a left clamping jaw 1 and a right clamping jaw 6 which are oppositely arranged. The inner vertical surfaces of the left clamping jaw 1 and the right clamping jaw 6 clamp the left and right end faces of the pipe clamp 2. The left clamping jaw 1 and the right clamping jaw 6 are connected to a cylinder 5 arranged above, for driving the left clamping jaw 1 and the right clamping jaw 6 to open or close. Protrusions 7 are respectively and correspondingly arranged on the inner vertical surfaces of the left clamping jaw 1 and the right clamping jaw 6, and the protrusions 7 correspond to the positions of the second chambers 8 on the pipe clamp 2. When the protrusions 7 slide into the second chambers 8, the gaps of the second chambers 8 are enlarged, and the needle 3 passes through the pipe holes on the front and back sides of the pipe clamp 2 and penetrates through the pipe clamp 2.

[0028] The protrusion 7 is in a quadrilateral shape, and the four pointed corners of the protrusion 7 abut against the opening and the bottom position of the second chamber 8, for expanding and increasing the opening space of the second chamber 8. Each triangular point of the protrusion 7 is respectively provided with a transition slope 12.

[0029] The pipe clamp 2 is placed in the groove 9 on the base 4, and fixing columns 10 are arranged on both sides of the groove 9, and the fixing columns 10 on both sides are used to straighten the pipe clamp 2.

[0030] At least one side of the inner vertical surfaces of the left clamping jaw 1 and the right clamping jaw 6 is provided with an inclined surface 11, and the inclined surface 11 is located above the protrusion 7 for stabilizing the upper end part at the opening of the second chamber 8.

[0031] When Embodiment 1 and Embodiment 2 provided by the present utility model are implemented, the working process is as follows: The air cylinder 5 drives the left jaw 1 and the right jaw 6 to move downward. When moving to a suitable position, the air cylinder 5 drives the left jaw 1 and the right jaw 6 to clamp the left and right sides of the pipe clamp 2. At this time, the triangular or quadrangular protrusions of the left jaw 1 and the right jaw 6 slide into the second chamber 8 of the pipe clamp 2 through the transition slope 12 and support the inner wall of the second chamber 8, increasing the gap of the second chamber 8; after the gap of the second chamber 8 increases, the air cylinder 5 drives the pipe clamp 2 to rise away from the base 4. After reaching the position, the air cylinder 5 continues to drive the left jaw 1, the right jaw 6 and the pipe clamp 2 to move forward, so that the needle-passing device 3 withdraws; when the needle-passing device 3 withdraws, the heparin tube enters the pipe clamp 2 at the same time. Since the triangular or quadrangular protrusions can continue to support the inner wall of the second chamber 8 to ensure that the gap of the second chamber 8 remains unchanged, when the needle-passing device 3 withdraws, the pipe clamp 2 can be successfully threaded; finally, the left jaw 1 and the right jaw 6 open, completing the pipe threading process.
