Description

Technical Field

[0001] This utility model relates to the field of drainage tubes, and in particular to a pulse flushing drainage tube. Background Technology

[0002] As a key instrument for achieving precise irrigation therapy, the patency and structural stability of pulsed irrigation drainage tubes directly affect the transmission efficiency of pulse pressure and the irrigation effect. In existing technologies, the drainage tubing of pulsed irrigation drainage tubes is typically designed as a flexible structure with a certain length to adapt to the irrigation operation requirements in different scenarios. However, these drainage tubes lack a dedicated storage and fixing structure when not in use, leading to the tubes easily becoming scattered and disorganized.

[0003] In actual clinical practice, unsecured drainage tubes often sway due to their own weight or external contact, leading to entanglement or contact with other medical devices. This entanglement not only requires medical staff to spend extra time manually untangling the tubes, prolonging preoperative preparation and postoperative cleanup, but may also cause tube displacement or surface abrasion due to excessive pulling during the untangling process. For pulse irrigation drainage tubes, the twisting caused by entanglement alters the cross-sectional shape of the lumen. When the pulse irrigation device is activated, the twisted areas are prone to sudden changes in fluid resistance, causing interruption or attenuation of pulse pressure transmission, reducing the pulse impact force of the irrigation fluid, and affecting the removal of foreign objects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pulse flushing drainage tube.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pulse flushing drainage tube, comprising a drainage tube, a horizontally placed base, a pulse flushing device fixedly connected to the upper end face of the base in a vertical direction, and a bracket fixedly connected to the upper end face of the base on one side of the pulse flushing device in a vertical direction. The top of the bracket extends outward in a horizontal direction to form a hanging part, and a flushing bag is suspended on the bracket through the hanging part, with the flushing bag located diagonally above the pulse flushing device. The input end of the pulse flushing device is connected to the outlet of the flushing bag through a pipe in an inclined direction, and the output end of the pulse flushing device is connected through a pipe in an inclined direction... The drainage tube is connected to one end in the horizontal direction to form a fluid passage from the flushing bag to the pulse flusher to the drainage tube. The pulse flusher is equipped with a foot switch on its side. The foot switch can be rotated downward around its connection point with the pulse flusher. The foot switch is driven by the foot to rotate, thereby controlling the pulse flusher to start. This causes the flushing fluid in the flushing bag to spray out from the other end of the drainage tube along the above passage. The outer surface of the drainage tube is fitted with multiple connecting parts at intervals along its length. When the drainage tube is folded and stored along its length, two adjacent connecting parts can approach each other in the horizontal direction and adhere to each other to fix it, thereby restricting the unfolding of the drainage tube.

[0006] Preferably, the connecting part includes a clamping block, which has an arc-shaped structure. Its inner sidewall is in contact with the outer surface of the drainage tube, and the clamping block is clamped on the surface of the drainage tube along the radial direction. Adsorption parts are provided on the end faces of two adjacent clamping blocks that are close to each other. The adsorption parts can generate adsorption force in the horizontal direction to adsorb and fix the adjacent clamping blocks.

[0007] Preferably, the adsorption part includes a mounting groove formed on the end face of the clamping block. The mounting groove passes through the clamping block along the axial direction and has a magnetic block embedded inside. When two adjacent clamping blocks approach each other in the horizontal direction, the magnetic blocks on the two clamping blocks generate a magnetic attraction force, which fixes the clamping blocks to each other.

[0008] Preferably, the side of the clamping block is provided with an assembly groove along its radial direction. The opening of the assembly groove is arranged outward along the radial direction of the clamping block, and the depth of the assembly groove is adapted to the diameter of the drainage tube. The drainage tube can be inserted into the clamping block from the opening of the assembly groove along the radial direction of the clamping block. A tightening band is fixedly connected to the port of the assembly groove along the circumference of the clamping block. The free end of the tightening band can extend away from the port along the surface of the clamping block and adhere to the outer surface of the clamping block to press the drainage tube into the clamping block.

[0009] Preferably, a protective part is provided at the interface between the drainage tube and the pulse flushing device. The protective part extends along the axial direction of the drainage tube, and its inner sidewall fits against the outer surface of the drainage tube to form a wrapping and fixing at the interface.

[0010] Preferably, the protective part includes a plurality of clamping parts distributed along the axial direction of the drainage tube. Each clamping part includes a first clamping arm and a second clamping arm arranged opposite to each other. One end of the first clamping arm is provided with a rotating groove along its width direction. The corresponding position of the second clamping arm is provided with a through groove along its thickness direction. The rotating groove can be inserted into the through groove along its axial direction, and the rotating groove can rotate around the axis of the through groove, so that the first clamping arm and the second clamping arm open and close radially along the drainage tube. In two adjacent clamping parts, the free end of the first clamping arm of the preceding clamping part and the free end of the second clamping arm of the following clamping part are rotatably connected by a ball joint, so that the adjacent clamping parts can rotate relative to each other in the circumference of the drainage tube.

[0011] Preferably, an elastic band is connected between the ball-shaped parts of two adjacent clamping parts along the axial direction of the drainage tube. When the elastic band is in its natural state, it generates a pulling force along the axial direction, causing the ball-shaped parts to move closer to each other, thereby driving the first clamping arm and the second clamping arm to rotate in opposite directions around the axis of the through groove, so that the clamping parts are tightened radially and clamped on the surface of the drainage tube, thereby limiting the radial bending at the interface of the drainage tube.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the drainage tube is easier to store. The connecting part can be quickly fixed when the drainage tube is folded by the adsorption of the clamp and the magnetic block, which avoids the tube from being scattered and tangled, saves storage space and makes it easy to unfold quickly when used next time. At the same time, it reduces the wear and tear caused by the tube being placed randomly. Attached Figure Description

[0021] Example 1, such as Figure 1-6As shown, a pulse flushing drainage tube 6 includes a drainage tube 6. A base 1 is placed horizontally on the working surface. A pulse flusher 5 is fixedly connected to the upper end face of the base 1 in the vertical direction, and the bottom of the pulse flusher 5 is in close contact with the upper end face of the base 1. A bracket 3 is also fixedly connected to the upper end face of the base 1 in the vertical direction on one side of the pulse flusher 5, with a certain gap between the bracket 3 and the pulse flusher 5. The top of the bracket 3 extends horizontally away from the pulse flusher 5 to form a hanging part. The end of this hanging part is slightly bent downward. The flushing bag 4 is suspended on this hanging part by a hanging rope at the bag opening. At this time, the flushing bag 4 is obliquely above the pulse flusher 5, with the bag opening facing the input end of the pulse flusher 5. A pipe is connected to the input end of the pulse flusher 5. This pipe extends obliquely upward from the input end of the pulse flusher 5 and finally connects to the outlet of the flushing bag 4. The pipe forms a certain angle with the vertical direction. The output end of the pulse flusher 5 is also connected to a pipe. This pipe extends horizontally outward from the output end of the pulse flusher 5 and connects to one end of the drainage tube 6. The pipe remains horizontal, thus forming a fluid passage from the flushing bag 4 to the pulse flusher 5 and then to the drainage tube 6. A foot switch 2 is located on the side of the pulse flusher 5. The foot switch 2 protrudes horizontally from the surface of the pulse flusher 5, and its connection point with the pulse flusher 5 is a rotating shaft. When the pulse flusher 5 needs to be activated, the foot is pressed at the end of the foot switch 2, which rotates downward around this rotating shaft until it contacts the upper surface of the base 1, at which point the pulse flusher 5 is triggered. Multiple connecting parts 8 are spaced along the length of the outer surface of the drainage tube 6. Each connecting part 8 includes a clamping block 81, which is arc-shaped. The arc of the inner wall matches the arc of the outer surface of the drainage tube 6. The clamping block 81 is radially clamped onto the drainage tube 6, and its inner wall is tightly fitted to the outer surface of the drainage tube 6. The clamping block 81 has a radially formed mounting groove 8476 on its side. The opening of the mounting groove 8476 faces outward, and its depth is just enough to accommodate the drainage tube 6. The drainage tube 6 can be radially inserted into the clamping block 81 from the opening of the mounting groove 8476. A tightening strap 83 is fixedly connected to the port of the mounting groove 8476. One end of the tightening strap 83 is fixed to one side of the port, and the other end is a free end. The free end can pass through a pre-set through hole on the surface of the mounting groove 8476 and then be attached to the outer surface of the clamping block 81 by Velcro, thus pressing the inserted drainage tube 6 tightly into the clamping block 81. An installation groove 82 is formed on the end faces of the clamping blocks 81 that are close to each other. The installation groove 82 passes through the clamping block 81 along the axial direction and embeds a magnetic block in the installation groove 82. The magnetic blocks on adjacent clamping blocks 81 have opposite polarities. When the drainage tube 6 needs to be folded for storage, the drainage tube 6 is folded along its length. The adjacent clamps 81 will move closer to each other under the action of the drainage tube 6. At this time, the magnetic blocks on the two clamps 81 will be tightly attracted together due to the attraction of opposite poles, thus fixing the folded drainage tube 6.A protective part 7 is fitted at the interface between the drainage tube 6 and the pulse flushing device 5. The protective part 7 extends along the axial direction of the drainage tube 6, covering the interface and a section of the drainage tube 6 nearby. The protective part 7 includes multiple clamping parts, which are distributed sequentially along the axial direction of the drainage tube 6. Each clamping part has a first clamping arm 71 and a second clamping arm 72. One end of the first clamping arm 71 and the second clamping arm 72 are close to each other. The surface of the first clamping arm 71 has a rotating groove 75, which is a cylindrical protrusion. A through groove is opened at the corresponding position of the second clamping arm 72. The shape of the through groove matches the rotating groove 75. The rotating groove 75 is inserted into the through groove, so that the first clamping arm 71 and the second clamping arm 72 can rotate around the contact point between the rotating groove 75 and the through groove, realizing the opening and closing of the clamping part. In two adjacent clamping parts, the free end of the first clamping arm 71 of the preceding clamping part and the free end of the second clamping arm 72 of the following clamping part are connected by a ball-and-socket part 73. The ball-and-socket part 73 consists of a ball and a socket. The ball is fixed to the end of one clamping arm, and the socket is located at the end of the other clamping arm. The ball can rotate freely within the socket. An elastic band 74 is connected between each ball-and-socket part 73. In its natural state, the elastic band 74 is in a tightened state, which pulls the adjacent ball-and-socket parts 73 closer together. This, in turn, causes the first clamping arm 71 and the second clamping arm 72 to rotate towards each other around the contact point between the rotating groove 75 and the through groove, so that the clamping part is tightly clamped on the surface of the drainage tube 6.

[0022] Working principle: The flushing fluid in the flushing bag 4 flows into the pulse flusher 5 through the pipeline. When the foot switch 2 is pressed, the pulse flusher 5 starts and generates periodic pulse pressure. This pulse pressure drives the flushing fluid to form a pulsed flow in the pipeline, causing the flushing fluid to be sprayed out from the end of the drainage tube 6 in a pulsed form. The impact force of the pulse enhances the flushing effect on the target area. The protective part 7, through the continuous clamping action of the clamping part, prevents the bending of the drainage tube 6 at the interface with the pulse flusher 5 due to the pulse pressure, ensuring stable delivery of the pulse flushing fluid. When the drainage tube 6 is not in use, the connecting part 8 uses magnetic blocks to fix the folded drainage tube 6, preventing it from shaking and affecting the normal operation of the next pulse flush. When it is necessary to store the drainage tube 6, the drainage tube 6 is folded along its length. The clamps 81 of adjacent connecting parts 8 move closer to each other under the action of the drainage tube 6. The magnetic blocks in the clamps 81 attract each other due to the attraction of opposite poles, fixing the folded drainage tube 6 and preventing it from spreading out. Under the pull of the elastic band 74, the clamping part in the protective part 7 tightly clamps the drainage tube 6 by the opposite rotation of the first clamping arm 71 and the second clamping arm 72. At the same time, the ball part 73 allows the clamping part to rotate with the slight movement of the drainage tube 6, so as to avoid the interface between the drainage tube 6 and the pulse flushing device 5 from being blocked or damaged due to bending.
