Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical drainage, in particular to a manual dredging device for a drainage tube. Background Art
[0002] In current clinical treatment and nursing, clinical drainage operations such as surgical wound drainage and sputum suction nursing drainage all require the use of drainage devices, and drainage tubes are essential accessories for drainage devices.
[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 intercepted (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. The rapid squeezing makes the fluid or gas impact the blockage. For blockages that are easily dispersed, it only takes a few squeezes 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 clearing device to meet the needs. Utility Model Content

[0023] 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.
[0024] Example: Reference Figure 1 , push 2, Figure 5 and Figure 6 The manual unclogging device for drainage tubes shown in the figure comprises a shell 1 with a through hole 104 adapted to the drainage tube, a hand pressure block 2, a lower pressure plate 6, and a cut-off block 9 whose lower end is located below the lower pressure plate 6. The lower end of the hand pressure block 2 is slidably arranged in the inner cavity of 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. A T-shaped rod 4 is fixed to the upper end of the lower pressure plate 6, and the upper end of the T-shaped rod 4 slides through the transverse plate 18. The outer sleeve of the T-shaped rod 4 is provided with a return spring 5. , and the upper and lower ends of the return spring 5 are in contact with the top plate of the T-shaped rod 4 and the upper end of the cross plate 18 respectively, a lower pressure block 7 is fixed to the left end of the lower pressure plate 6, and the left end of the lower pressure block 7 is located in the rectangular cavity of the cut-off block 9, a buffer spring 11 is fixed in the rectangular cavity, and the upper end of the buffer spring 11 is fixedly connected to the lower pressure block 7, the cut-off block 9 is slidably connected to the shell 1 through a limiting slider 10 arranged on the side wall, a lower pressure column 3 is fixed to the inner cavity of the shell 1, and the lower pressure column 3 is connected to the upper end of the T-shaped rod 4.
[0025] 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 with one hand and move it close to the blocked area. The fingers quickly apply force inward to make the hand pressure block 2 move quickly toward the inner cavity of the shell 1. In this process, the T-shaped rod 4 is driven by the lower pressure column 3 to compress the return spring 5 downward, and 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 the drainage tube and squeeze the drainage tube, thereby intercepting the fluid at this location. (i.e. the fluid cannot pass through here), 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. When the hand pressure block 2 can no longer continue to move toward the inner cavity of the shell 1, the finger is released, and the elastic force of the reset spring 5 and the buffer spring will restore the T-bar, the hand pressure block 2, the lower pressure plate 6 and the intercepting block 9 to their original positions. For blockages that are difficult to disperse, the shell 1 can be moved with one hand, approached again, and the hand pressure block 2 is pressed to impact the blockage again. This process is repeated to flush the blockage into the overflow bottle.
[0026] It should be noted that: 1. The purpose of using the intercepting block 9 to cut off the drainage tube 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; 2. 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; 3. The inner cavity of the shell 1 is provided with a blocking step 8, which can contact the lower end of the hand pressure block 2 to hinder the continued downward movement of the hand pressure block 2, so as to avoid excessive squeezing and affect the service life of the internal components; 4. 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.
[0027] As a preferred implementation in this embodiment, Figure 5 As shown, the lower pressure column 3 is connected to the upper end of the T-shaped rod 4 through a labor-saving unit, and the labor-saving unit includes a U-shaped frame 12 installed in the inner cavity of the shell 1 and two first force arms 14 arranged to rotate crosswise 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 set on the U-shaped frame 12, the upper ends of the two first force arms 14 are rotatably set 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 lower pressure column 3 through a second pin shaft, the lower ends of the two first force arms 14 are rotatably set with T-shaped sliders 15, and the lower ends of the two T-shaped sliders 15 are slidably set in the T-shaped slide groove provided on the top plate of the T-shaped rod 4.
[0028] The provision of a labor-saving unit can make the operation of the medical staff more labor-saving. Through the downward movement of the lower pressure column 3, the lower ends of the two second force splitters 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. After the fingers are released, under the action of the elastic force of the reset spring 5, the various components return to their original positions. Among them, 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 medical staff can use less force to overcome the resistance of the reset spring 5 and the buffer spring 1 and make the T-shaped rod 4 move quickly (the faster the T-shaped rod 4 moves, the better the subsequent instantaneous squeezing effect with the drainage tube, which is conducive to flushing away or removing the blockage).
[0029] As a preferred implementation in this embodiment, Figure 5 As shown, a power-assisting unit is also included to assist the lower pressing plate 6 to move downward quickly and form compression with the drainage tube.
[0030] The purpose of setting the power-assisting unit is to reduce the movement resistance of the lower pressure plate 6 and increase the collision speed between the lower pressure plate 6 and the drainage tube, which is beneficial to clearing the blockage.
[0031] As a preferred implementation in this embodiment, Figure 5 As shown, the power assist unit includes a first magnet 13 and a second magnet 17 that are arranged opposite to each other. The second magnet 17 is fixedly mounted on the lower end of the top plate of the T-shaped rod 4. The first magnet 13 is arranged on the upper end of the cross plate 18. The magnetic poles of the first magnet 13 and the second magnet 17 at the opposite ends are opposite.
[0032] At the beginning, the first magnet 13 and the second magnet 17 have no or very little magnetic effect due to the large distance between them. After the T-bar 4 moves downward, the distance between them decreases, and a magnetic attraction is generated between the two magnets, which assists the T-bar 4 in compressing the movement of the return spring 5, thereby accelerating the movement speed of the lower pressure plate 6, so that the pressure in the drainage tube increases instantly after squeezing, which is more conducive to flushing away or removing the blockage. When the hand releases the hand pressure block 2, the return spring 5 overcomes the magnetic force between the two magnets and drives the components to return to their original positions.
[0033] 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.
[0034] 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.
[0035] 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 .
[0036] As a preferred implementation in this embodiment, Figure 3 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 .
[0037] 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 .
[0038] 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.
