[0015] 1. In the present invention, when the ball head is engaged and positioned with the surface of the plastic clamp head, the plastic clamp head is prevented from separating from the fixed head, and the O-ring is sealed to prevent dirt from flowing out. During disassembly, the movement of the sliding ring drives the linkage plate to move together, so that the U-shaped plate is forced to slide along the surface of the inclined surface, and at this time, the push rod is driven to slide on the inner wall of the support plate to rise in height.

[0038] By setting the arc plate 26, the opening of the guide arc groove 25 is blocked and sealed. By setting the connecting rod 28, the connecting rod 28 drives the L-shaped plate 29 to rotate. By setting the annular sealing ring 35, the dirt in the collection box 2 is prevented from flowing out of the guide arc groove 25 during the movement of the arc plate 26, thereby playing a sealing role.

[0039] As a preferred implementation in this embodiment, the inner top wall of the collection box 2 is fixedly connected with a positioning plate 36, one side of the positioning plate 36 is fixedly connected with an arc-shaped telescopic rod 27, one end of the arc-shaped telescopic rod 27 is fixedly connected to the surface of the connecting rod 28, and the surface of the arc-shaped telescopic rod 27 is sleeved with a second spring 37.

[0040] The positioning plate 36 is provided to realize positioning support for the arc-shaped telescopic rod 27 , and the second spring 37 is provided to drive the connecting rod 28 to rotate and stretch the second spring 37 so that the connecting rod 28 can be reset.

[0041] In this embodiment, an L-shaped plate 29 is fixedly connected to the surface of the connecting rod 28, and the bottom end of the L-shaped plate 29 is rotatably connected to the inner bottom wall of the collecting box 2. A cross baffle 32 is fixedly connected to the surface of the L-shaped plate 29, and a sealing gasket 30 is fixedly connected to the inner wall of the cross baffle 32, and the sealing gasket 30 is in extrusion contact with the inner bottom wall of the collecting box 2.

[0042] By setting the L-shaped plate 29, the L-shaped plate 29 can be rotated to change the angular position of the cross baffle 32. When the cross baffle 32 is in the default position, the sealing gasket 30 fixed on the inner wall thereof blocks and contacts the upper surface of the sewage discharge head 33 to perform sealing. When the cross baffle 32 is rotated to a certain angle, the sewage discharge head 33 can be opened to discharge the dirt in the collection box 2. Clean water can be added through one end of the second conduit 4 to perform an overall cleaning operation, so that the drive box 3, the first conduit 1, and the collection box 2 connected to the second conduit 4 can be recycled and will not contact with the patient's blood to cause infection.

[0043] As a preferred implementation in this embodiment, a first dustproof sticker 21 is fixedly connected to one side of the suction cup 6, and a second dustproof sticker 20 is fixedly connected to one side of the disposable adhesive sticker 7.

[0044] By providing the first dustproof sticker 21 and the second dustproof sticker 20, when the patient uses the sticky suction cup 6, the first dustproof sticker 21 and the second dustproof sticker 20 need to be torn off first, thereby increasing the life of the disposable sticky sticker 7 and allowing the suction cup 6 as a whole to be preserved for a longer period of time.

[0045] The working principle of the present invention is: a wound fixing drainage device, first tear off the first dustproof sticker 21 and the second dustproof sticker 20, stick the suction cup 6 to the surgical wound of the patient, if the drainage effect of the patient is poor, the first electric drive gear 22 can be started, the first electric drive gear 22 rotates to drive the second gear 23 to rotate, the second gear 23 rotates in the opposite direction to the first electric drive gear 22, the blood or dirt in the wound is drained, and the dirt is introduced into the collection box 2 through the first catheter 1 for collection. When the patient finishes the drainage treatment, in order to recycle the second catheter 4 and the drive box 3, the first catheter 1, and the collection box 2 as a whole, In order to avoid infection caused by the next patient's use, the plastic clamp head 8 can be disassembled and separated from the fixed head 9, and the sliding ring 16 can be pushed in the direction close to the force circle 18. At this time, the sliding ring 16 drives the linkage plate 15 to move together, so that the U-shaped plate 14 is forced to slide along the surface of the inclined surface 39, and at this time, the push rod 13 is driven to slide on the inner wall of the support plate 12 to rise in height. The rise of the push rod 13 drives the connected ball head 31 to move in the direction away from the annular groove 10, so that the ball head 31 is separated from the annular groove 10, and the clamping and positioning state of the plastic clamp head 8 is released. At this time, the suction cup 6 and the plug-in tube 5 after use can be recycled. , flush the interior of the fixed head 9 with disinfectant and clean water, and the disinfectant and clean water enters the collection box 2 through the second conduit 4 and the first conduit 1 to flush the interior of the collection box 2. This can effectively save medical equipment. At the same time, replacing a new suction cup 6 can also prevent the next patient from using it to get infected. When flushing the collection box 2, it is necessary to push the toggle protrusion 34 with a finger. The movement of the toggle protrusion 34 drives the connecting rod 28 and the arc plate 26 to move as a whole. At this time, the battery pack 38 performs a water-blocking and sealing operation on the guide arc groove 25. The connecting rod 28 drives the L-shaped plate 29 to rotate together, and the L-shaped plate 29 drives the cross baffle 32 to rotate together. The cross baffle 32 The rotation of the baffle 32 causes the sealing gasket 30 that was originally in compression contact with the surface of the sewage head 33 to be separated from the surface of the sewage head 33, and the flushing water source is discharged. The connecting rod 28 moves to stretch the second spring 37 to become longer. When cleaning is completed, the push-button 34 can be released, and the second spring 37 drives the connecting rod 28 and the L-shaped plate 29 to reset as a whole, so that the sealing gasket 30 on the cross baffle 32 is pressed against the surface of the sewage head 33 again. With the above structure, the drainage operation is assisted, and the interior can be cleaned and reused at the same time. In practical use, it is glued and fixed to avoid cross contamination caused by secondary use.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
