[0003] During the actual use of the drainage tube, the drainage tube is often blocked. At this time, the medical staff will pinch the drainage tube with the index finger and thumb of one hand (near the blockage), so that the fluid in the pinched part cannot pass, that is, the flow is cut off (to avoid the subsequent backflow of the fluid), and the index finger and thumb of the other hand are close to the pinched part and quickly squeeze the drainage tube. Through the rapid squeezing, the fluid or gas impacts the blockage. For blockages that are easily dispersed, it is only necessary to squeeze a few times near the blockage to clear the drainage tube. For substances that are not easy to be dispersed, the blockage will be moved in the drainage tube after squeezing. As the blockage moves, the interception point and the squeezing point need to be continuously changed until the blockage is flushed into the drainage bottle; in the above operations, both hands are required to cooperate (one hand for interception and the other hand for squeezing), which makes the whole operation more troublesome. Therefore, the present application provides a manual drainage tube unblocking device to meet the needs.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1 , Figure 5 The electric dredging device for drainage tubes shown in the figure comprises a shell 1 with a through hole 104 adapted to the drainage tube, a hand grip block 2, a lower pressure plate 6, a cut-off block 9 whose lower end is located below the lower pressure plate 6, and a driving motor 13 installed on a U-shaped frame 12, the lower end of the hand grip block 2 is fixed to the shell 1, the inner cavity of the shell 1 is provided with a transverse plate 18, the lower pressure plate 6 is located below the transverse plate 18, the upper end of the lower pressure plate 6 is fixed with a T-shaped rod 4, and the upper end of the T-shaped rod 4 slides through the transverse plate 18, the left end of the lower pressure plate 6 is fixed with a lower pressure block 7, and the left end of the lower pressure block 7 is located A buffer spring 11 is fixed in the rectangular cavity of the cut-off block 9, and the upper end of the buffer spring 11 is fixedly connected to the lower pressing block 7. The cut-off block 9 is slidably connected to the housing 1 through a limit slider 10 arranged on the side wall. A reciprocating screw rod 3 is rotatably arranged between the upper end of the U-shaped frame 12 and the inner wall of the hand-grip block 2, and a moving seat 20 is threadedly sleeved on the reciprocating screw rod 3. The moving seat 20 is connected to the upper end of the T-shaped rod 4 through a connecting piece. A transmission gear 5 is fixedly sleeved on the reciprocating screw rod 3, and the driving gear 8 on the output shaft of the driving motor 13 is meshed and connected with the transmission gear 5;

[0023] The housing 1 also includes a control switch 19 for controlling the operation of the drive motor 13 and a power supply 17 for providing electrical energy to the drive motor 13 .

[0024] When in use, the drainage tube can be passed through the through hole 104 so that the shell 1 is sleeved on the drainage tube. After completion, when the drainage tube is blocked, the medical staff can hold the shell 1 and the grip block 2 with one hand and move it close to the blocked area. The finger presses the control switch 19 to control the drive motor 13 to work, and the meshing connection between the drive gear 8 and the transmission gear 5 drives the reciprocating screw rod 3 to rotate, and the T-shaped rod is driven downward by the moving seat 20. The downward movement of the T-shaped rod 4 will drive the lower pressure plate 6 and the intercepting block 9 to move downward. Since the lower end of the intercepting block 9 is located below the lower pressure plate 6, the intercepting block 9 will first contact with the drainage tube and squeeze the drainage tube, thereby A cutoff is formed (i.e., the fluid cannot pass through here), and then the lower pressure plate 6 compresses the buffer spring 11 and continues to move downward, eventually forming a rapid squeeze with the upper end of the drainage end, and the fluid or gas in the drainage tube impacts the blockage, thereby dispersing or flushing the blockage. As the reciprocating screw rod 3 continues to rotate, the moving seat 20 drives the lower pressure plate 6 to move upward, and eventually the T-bar 4, the lower pressure plate 6, the cutoff block 9 and other components are restored to their original positions. For blockages that are difficult to disperse, the shell 1 can be moved by one hand, approached again, and the drive motor 13 can be controlled to work again to impact the blockage again, and this process is repeated until the blockage is flushed into the overflow bottle. Electric operation can effectively reduce labor intensity.

[0025] It should be noted that: First, the drainage tube is cut off by the intercepting block 9, that is, the purpose is to prevent the lower pressure plate 6 from being squeezed with the drainage tube, causing the fluid to flow back into the patient's body; second, the lower end of the lower pressure plate 6 is set as a plane, so that the pressure is evenly distributed on the contact surface, which can make the air pressure in the drainage tube instantly increase, and it is easier to have a greater impact force on the blockage, so that the blockage can be easily dispersed or washed away; third, the lower end of the intercepting block 9 is set as a triangular structure, and the tip is set downward, which is easy to form an interception operation on the drainage tube; fourth, a groove adapted to the finger can be set at the upper end of the hand-grip block 2 (to play an anti-slip role), and the control switch 19 is set in the groove, which is convenient for medical staff to control the operation of the drive motor 13 by pressing with their fingers.

[0026] As a preferred implementation in this embodiment, Figure 5 As shown, the connecting member includes two first force arms 14 that are rotatably arranged through a first pin shaft, the first pin shaft is located below the midpoint of the two first force arms 14, one end of the first pin shaft is rotatably arranged on the U-shaped frame 12, the upper ends of the two first force arms 14 are rotatably arranged with second force arms 16, and the opposite ends of the two second force arms 16 are arranged obliquely downward, the lower ends of the two second force arms 16 are rotatably connected to the moving seat 20 through the second pin shaft, the lower ends of the two first force arms 14 are rotatably arranged with T-shaped sliders 15, and the lower ends of the two T-shaped sliders 15 are slidably arranged in the T-shaped slide groove provided on the top plate of the T-shaped rod 4.

[0027] The connecting piece constitutes a labor-saving structure, which can save energy for the driving motor 13. Through the downward movement of the movable seat 20, the lower ends of the two second force arms 16 move downward, and then the upper and lower ends of the two first force arms 14 move closer together, and finally the T-shaped rod 4 moves downward. As the reciprocating screw rod 3 continues to rotate, the second force arm 16 and the first force arm 14 will return to their original positions. During this process, the T-shaped rod 4 will move upward, and this process is repeated to form a continuous up and down movement of the T-shaped rod 4, and then the lower pressure plate 6 forms a continuous extrusion of the drainage tube, wherein the power arm length of the first force arm 14 is greater than the resistance arm length, forming a labor-saving lever, so that the driving motor 13 can output a smaller force to make the T-shaped rod 4 move up and down quickly (the faster the T-shaped rod 4 moves, the better the subsequent instantaneous extrusion effect with the drainage tube, which is conducive to flushing away or removing the blockage).

[0028] As a preferred implementation in this embodiment, Figure 5 As shown, the diameter of the driving gear is smaller than the diameter of the transmission gear 5 .

[0029] The small gear is used to drive the large gear to rotate, and since a labor-saving lever is formed, the driving motor 13 is more energy-efficient when working, and the working time of the dredging device can be extended.

[0030] As a preferred implementation in this embodiment, Figure 1-4 As shown, the shell 1 includes an upper shell 101 and a lower shell 102 with an accommodating opening, the lower shell 102 and the upper shell 101 are rotatably connected by a rotating shaft 103, a U-shaped block 105 is fixed on the side wall of the lower shell 102, and a threaded tube 108 is rotatably arranged in the U-shaped cavity of the U-shaped block 105, and the threaded tube 108 is threadedly sleeved on the screw 107, a rotating block 109 of a columnar structure is fixed to the upper end of the screw 107, a fixing plate 106 is fixed on the side wall of the upper shell 101, a circular through hole matching the size of the rotating block 109 is arranged on the fixing plate 106, the inner cavity of the circular through hole is provided with an annular supporting step, an opening 110 matching the screw 107 is provided on the fixing plate 106, and the inner cavity of the opening 110 is communicated with the inner cavity of the circular through hole.

[0031] When in use, the drainage tube is clamped into the accommodating openings provided on the upper shell 101 and the lower shell 102. After completion, the upper shell 101 and the lower shell 102 are rotated and closed, and then the screw 107 is rotated to make the screw 107 rotate from the opening to the top of the fixed plate 106. At this time, the rotating block 109 is rotated so that the lower end of the rotating block 109 contacts the annular support step to form a limit, thereby completing the fixation of the upper shell 101 and the lower shell 102, which facilitates the installation and connection of the dredging device and the drainage tube.

[0032] It should be noted that an elastic fastening pad is provided on the upper end surface of the annular support step to improve the stability of the threaded fixation between the screw rod 107 and the threaded tube 108 .

[0033] As a preferred implementation in this embodiment, Figure 4 As shown, a baffle 111 is fixed to the lower end of the screw rod 107 , and the diameter of the baffle 111 is greater than the diameter of the threaded tube 108 .

[0034] The baffle 111 can block the lower end of the threaded tube 108 to prevent the screw rod 107 from being separated from the threaded tube 108 .

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
