[0053] The electromagnet housing 200 is provided in two groups and is fixed on both sides of the top of the base 100;

[0054] A fixed clamping frame 300, which is detachably fixed to the inner side of the electromagnet housing 200;

[0055] The movable clamping frame 400 is slidably mounted on the top of the base 100 and squeezes the drainage tube when sliding, so that the drainage tube between the fixed clamping frame 300 and the movable clamping frame 400 is in a collapsed state;

[0056] The clamping assembly 500 is provided with two clamping assemblies 500, and is respectively installed in the fixed clamping frame 300 and the movable clamping frame 400, and squeezes the drainage tube under the magnetic force of the electromagnet.

When the fixed clamping frame 300 opens the drainage tube, a negative pressure is formed in the drainage tube cavity to drain the accumulated fluid into the drainage tube, thereby draining the accumulated fluid more fully and cleanly, shortening the time of indwelling the drainage tube, and avoiding the backflow of the drainage material in the tube to reduce the retrograde infection rate.

[0058] The drainage tube is clamped and fixed by the fixed clamping frame 300, which reduces the discomfort and pain caused by the movement of the tube when squeezing the drainage tube;

[0059] Among them, an electromagnet is installed inside the electromagnet housing 200, and the two groups of electromagnet housings 200 correspond to the fixed clamping frame 300 and the movable clamping frame 400 respectively, controlling the status of the fixed clamping frame 300 and the movable clamping frame 400, and there is a certain distance between the two groups of electromagnet housings 200, and a magnetically insulating material can be set between them to avoid the two groups of electromagnets from affecting each other.

[0060] In some embodiments of the present invention, referring to Figure 2 As shown, the fixed clamping frame 300 and the dynamic clamping frame 400 both include:

[0061] L-shaped frame 310, two L-shaped frames 310 are provided and are located between two electromagnet housings 200;

[0062] The socket joint 320 is fixed to the outside of the L-shaped frame 310 and connected to the electromagnet housing 200;

[0063] The receiving sleeve 330 is sleeved on the outside of the drainage tube, and the two receiving sleeves 330 are fixed together by a clamp.

[0064] The L-shaped frame 310 and the socket 320 are matched and arranged to contact the electromagnet housing 200, so that the electromagnet housing 200 limits the sliding direction of the L-shaped frame 310, thereby preventing the L-shaped frame 310 from deflecting during the sliding process;

[0065] The socket 320 is sleeved on the outside of the drainage tube, and the two L-shaped frames 310 are fixed together with the cooperation of the clamp, so that the two clamping assemblies 500 can move synchronously and the clamping assemblies 500 can squeeze the drainage tube normally.

[0066] In some embodiments of the present invention, referring to Figure 2 As shown, a hinge frame 340 is fixedly installed on the inner side of the L-shaped frame 310 , and a guide plate 350 is fixedly installed on the outer side of the L-shaped frame 310 .

[0067] The coordinated arrangement of the articulated frame 340 and the guide plate 350 can ensure the normal installation of the clamping assembly 500, so that the clamping assembly 500 can normally squeeze or release the drainage tube.

[0072] The traction rope 540 has two ends connected to the magnetic sliding member 530 and the extrusion assembly 510 respectively, so that the extrusion assembly 510 and the magnetic sliding member 530 move synchronously.

[0073] The elastic rope 520 is arranged to stretch and store force when the extrusion assembly 510 rotates to extrude the drainage tube, and after the external force on the extrusion assembly 510 disappears, the elastic rope 520 drives the extrusion assembly 510 to reset.

[0074] The traction rope 540 can be set so that when the magnetic sliding member 530 slides, the squeezing assembly 510 can be driven to rotate and squeeze the drainage tube, and when the squeezing assembly 510 is reset, the magnetic sliding member 530 can be pulled to slide and reset.

[0075] In some embodiments of the present invention, referring to Figure 3 and Figure 4 As shown, the extrusion assembly 510 includes:

[0076] A rotating frame 511, the rotating frame 511 is rotatably installed in the articulated frame 340 and connected to the traction rope 540 and the elastic rope 520;

[0078] The rotating frame 511 is connected with the traction rope 540 and the elastic rope 520, so that the traction rope 540 and the elastic rope 520 control the rotation state of the rotating frame 511. At the same time, the rotating frame 511 can also be extended to the outside of the L-shaped frame 310, so that the squeezing roller 512 can contact the squeezing roller 512 on the fixed clamping frame 300.

[0079] The drainage tube is squeezed by the squeezing roller 512 , and can be rotated during movement to avoid pulling of the drainage tube due to friction, thereby preventing the drainage tube from being broken or damaged.

[0080] In some embodiments of the present invention, referring to Figure 3 and Figure 4 As shown, the magnetic sliding member 530 includes:

[0081] A sliding post 531, the sliding post 531 can slide through the guide plate 350;

[0082] A pulling plate 532, which is fixed to one end of the sliding column 531 and is fixedly connected to the pulling rope 540;

[0083] The metal plate 533 is fixed to the other end of the sliding column 531 and is attracted to the electromagnet housing 200 .

[0084] The slide post 531 cooperates with the guide plate 350 so that the guide plate 350 can orient the slide of the slide post 531 to prevent the slide post 531 from deflecting under the action of external force.

[0085] The pulling plate 532 is connected to the pulling rope 540, so that the pulling rope 540 can normally pull the sliding column 531 to move or the pulling plate 532 pulls the pulling rope 540 to move, and at the same time can limit the movement range of the sliding column 531;

[0086] The metal plate 533 is arranged inside the electromagnet housing 200, and after the electromagnet is energized, the sliding post 531 is driven to slide under the action of magnetic force.

[0087] In some embodiments of the present invention, referring to Figure 2 As shown, it also includes:

[0088] The threaded rod 600 can rotatably pass through the fixed clamping frame 300 and the movable clamping frame 400, and drive the clamping frame 400 to move when rotating;

[0089] The receiving plate 700 is fixed on the electromagnet housing 200 and is rotatably connected to the threaded rod 600 .

[0090] The threaded rod 600 is matched with the socket 320 and rotates under the drive of the motor, and the thread drives the movable clamping frame 400 to move, thereby changing the position of the movable clamping frame 400 and causing the drainage tube to collapse for a certain distance. At the same time, the threaded rod 600 is made of plastic material and is not affected by magnetic force.

[0091] The receiving plate 700 is fixedly connected to the receiving head 320 on the fixed clamping frame 300 by bolts, so that the position of the fixed clamping frame 300 is restricted and positioned.

[0092] Working method of the utility model:

[0093] When in use, the fixed clamping frame 300 is installed at a position 10 to 15 cm away from the skin insertion of the drainage tube, and then the dynamic clamping frame 400 is installed on the threaded rod 600, and the two sets of squeezing rollers 512 are in contact, and then the power is turned on to energize the electromagnet inside the electromagnet housing 200 and generate magnetic force. Under the action of the magnetic force, the metal plate 533 moves toward the electromagnet housing 200 and drives the sliding column 531 to move, so that the sliding column 531 drives the rotating frame 511 to rotate through the traction rope 540, so that the rotating frame 511 drives the two squeezing rollers 512 to get close to each other and squeeze the drainage tube to make it collapse, and then the motor or motor is started to drive the threaded rod 600 to rotate, and drive the dynamic clamping frame 400 to slide under the action of the thread, so that the dynamic clamp The holder 400 slides about 20 cm, and then the electromagnet power in the electromagnet housing 200 corresponding to the fixed clamping frame 300 is disconnected, so that the elastic rope 520 pulls the rotating frame 511 to reset, so that the squeezing roller 512 releases the squeezing of the drainage tube, and pulls the sliding column 531 and the metal plate 533 to reset. Due to the loosening of the fixed clamping frame 300, the drainage tube recovers and causes negative pressure in the lumen, causing the accumulated fluid to flow into the interior of the drainage tube, and then the electromagnet power in the electromagnet housing 200 corresponding to the moving clamping frame 400 is disconnected, so that the moving clamping frame 400 releases the squeezing of the drainage tube, and then the motor or motor is started, so that the motor or motor drives the threaded rod 600 to rotate and drives the moving clamping frame 400 to slide under the action of the thread, so that the moving clamping frame 400 moves to the initial position.
