Examples

As shown in fig. 1-5, the anti-backflow uterine cavity negative pressure suction device of the present embodiment includes a suction tube 10, a suction hole 11 formed in a side wall of an end of the suction tube 10, a blocking piece 20 for closing the suction hole 11, and a driving device for driving the blocking piece 20 to move along a length direction of the suction tube 10. Specifically, tissues, fluids, etc. in the uterine cavity are sucked through the suction holes 11 at the end of the suction tube 10. After the primary suction is temporarily finished, the baffle plate 20 is adjusted by the driving device, so that the baffle plate 20 can block the suction hole 11 at the end part of the suction tube 10, and the liquid in the suction tube 10 is prevented from flowing back to the human body through the suction hole 11 to cause unnecessary troubles and the like. When the suction is required again, the driving device is used to remove the baffle 20. Not only convenient operation, but also can effectively prevent liquid from flowing backwards. Since the suction tube 10 is connected to the negative pressure device and sucks the liquid through the suction holes 11, a small amount of the liquid remaining at the suction holes 11 does not have too much pressure on the flap 20. In addition, since the liquid enters the suction tube 10 from the outside through the suction hole 11, the stopper 20 does not suddenly block the suction hole 11, and the liquid cannot be sucked.

The driving device in the embodiment comprises a strip-shaped connecting piece 21 arranged in the suction tube 10, a driving block 22 and a sleeve 23 sleeved on the outer wall of the suction tube 10; one end of the connecting piece 21 is fixedly connected with the side wall of the baffle 20, and the other end is fixedly connected with the driving block 22; the connecting sheet 21 and the suction tube 10 are made of metal materials which cannot be attracted by a magnet; the driving block 22 is made of a metal material that can be attracted by a magnet; the sleeve 23 is provided with a first magnet. The connecting piece 21 is in an arc shape which is attached to the inner wall of the suction tube 10. Specifically, because the sleeve 23 is provided with the first magnet, the driving block 22 can be attracted, and the outer wall and the inner wall of the attraction tube 10 are smooth, the driving block 22 can move along the length direction of the attraction tube 10 under the driving of the first magnet, and then the connecting piece 21 pushes the blocking piece 20 to move, because the attraction tube 10 is thin, the attraction hole 11 and the blocking piece 20 are small, and the blocking piece 20 is thin, the blocking piece 20 can be pushed easily, and the connecting piece 21 is arc-shaped and made of metal material which is attached to the attraction tube 10, so that the connecting piece cannot be easily bent when being subjected to the thrust action of the driving block 22. In addition, since the connecting piece 21 and the suction tube 10 are made of a metal material that is not attracted by the magnet, the first magnet in the sleeve 23 does not affect the connection.

The connecting piece 21 and the suction tube 10 in this embodiment are both made of 316L stainless steel. Specifically, the 316L stainless steel is not only a metal material commonly used in clinical practice, but also cannot be attracted by a magnet, so that the application scenario of the technology is very satisfied.

The driving block 22 in this embodiment is provided with a second magnet, and the first magnet and the second magnet attract each other. The surface of the driving block 22 is coated with a teflon coating. Specifically, the first magnet and the second magnet are respectively arranged in the sleeve 23 and the driving block 22, so that the interaction between the first magnet and the second magnet can be effectively improved, the control on the baffle 20 is improved, and the baffle is prevented from moving under the washing of liquid. And the surface of the driving block 22 is coated with a highly inert polytetrafluoroethylene coating, so that the interaction between the driving block 22 and liquid can be effectively avoided, and the friction between the driving block 22 and the inner wall of the suction tube 10 can be reduced, so that the sliding is smoother.

The outer wall of the suction tube 10 in the embodiment is provided with an external thread protruding from the outer wall surface of the sleeve 23 at a position corresponding to the driving block 22; the inner wall of the sleeve 23 is provided with internal threads (not shown) which are threadedly coupled with the external threads. Specifically, use the screw thread to establish sleeve 23 on attracting pipe 10 outer wall, can prevent effectively that sleeve 23 from sliding outside attracting pipe 10 carelessly to set up convex external screw thread attracting pipe 10 outer wall, just so can be convenient take off sleeve 23 according to actual need.

In this embodiment, the suction tube further comprises a plurality of U-shaped fixture blocks 24 for limiting the connecting sheet 21, and both ends of the fixture blocks 24 are fixedly connected with the inner wall of the suction tube 10; the connecting piece 21 is arranged in a gap between the clamping block 24 and the suction tube 10 in a sliding way. Specifically, the latch 24 can effectively latch the connecting piece 21, and can effectively prevent the connecting piece from bending.

In this embodiment, the device further comprises a pair of sliding grooves arranged on the inner wall of the suction tube 10, and the pair of sliding grooves are respectively arranged on two sides of the suction hole 11; the two sides of the baffle 20 are respectively connected with a pair of sliding chutes in a sliding manner. Specifically, the chute effectively limits the flap 20 from shifting under the action of liquid.

The baffle 20 in this embodiment is made of 316L stainless steel.

In summary, the anti-reverse-flow uterine cavity negative pressure suction device of the present embodiment sucks the tissue, liquid, and the like in the uterine cavity through the suction hole 11 at the end of the suction tube 10. After the primary suction is temporarily finished, the baffle plate 20 is adjusted by the driving device, so that the baffle plate 20 can block the suction hole 11 at the end part of the suction tube 10, and the liquid in the suction tube 10 is prevented from flowing back to the human body through the suction hole 11 to cause unnecessary troubles and the like. When the suction is required again, the driving device is used to remove the baffle 20. Not only convenient operation, but also can effectively prevent liquid from flowing backwards. Since the suction tube 10 is connected to the negative pressure device and sucks the liquid through the suction holes 11, a small amount of the liquid remaining at the suction holes 11 does not have too much pressure on the flap 20.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
