Description

Technical Field

[0001] This utility model belongs to the field of drainage technology, and in particular relates to a drainage device that prevents seepage from wounds around the drainage tube. Background Technology

[0002] Drainage is a medical technique that uses physical or mechanical methods to remove pathological fluids (such as exudate, pus, blood) or gases from the body's cavities, wounds, or organs. Its core objectives are to reduce local pressure, control infection, promote tissue repair, and accelerate healing. Because proteins (such as fibrinogen) in body fluids (such as exudate and pus) are prone to coagulate into flocculent or cord-like deposits during drainage, especially when the drainage speed is slow, deposits easily adhere to the tube wall during drainage, leading to blockage of the drainage tube and resulting in exudation at the wound site. A drainage device that can avoid tube blockage is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a drainage device that prevents wound seepage around the drainage tube, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drainage device for preventing wound seepage around a drainage tube, comprising a ring sleeve symmetrically fitted onto a drainage tube, wherein the inner diameter of the ring sleeve is larger than the outer diameter of the drainage tube; positioning cylinders are symmetrically arranged on the upper and lower sides of the drainage tube, with the positioning cylinders positioned between two ring sleeves; a guide tube is fixedly connected to one end of the drainage tube, and a plug is threaded onto the guide tube; the device also includes an adjustment component for adjusting the distance between the two ring sleeves; and a connecting component for allowing the upper positioning cylinder to slide laterally.

[0005] Beneficial effects This invention provides a drainage device to prevent wound seepage around the drainage tube, which has the following advantages compared with the prior art: When it is necessary to clean the deposits on the inner wall of the drainage tube, the user removes the pressure rod from the positioning rod and pushes the connecting bracket to slide it onto the drainage tube. Since the inner diameter of the ring is larger than the outer diameter of the drainage tube, the ring can slide freely on the drainage tube without deforming it. The user should simultaneously press the two positioning cylinders, causing them to move towards each other and gradually contact the drainage tube during their sliding process, causing the drainage tube to deform until it is tightly compressed. At this point, the inner walls of the drainage tubes are in contact with each other. During this process, the pressure rod simultaneously compresses the spring A fixedly connected to it, thus putting it in a state of compression deformation. Therefore, when the user stops applying pressure to the positioning cylinders, the two positioning cylinders can quickly rebound to their original position under the action of their corresponding spring A. When the positioning cylinders have compressed the drainage tube, the user can then press the upper pull head while stabilizing the distance between the two positioning cylinders, causing the upper positioning cylinder to begin sliding laterally. At this point, the two positioning cylinders begin to move forward. The positioning cylinders slide relative to each other, causing the inner walls of the drainage tubes to rub against each other during the sliding process, thus dislodging the deposits on them. When drainage resumes, the deposits can be drawn out of the drainage tube. During this process, because spring B is fixedly connected between shaft B and the pressure rod, the upper positioning cylinder can quickly return to its original position when the user stops pressing the pull head, so that the positioning cylinder can be repeatedly pushed to slide during use, thereby increasing the cleaning effect on the deposits in the pipe. If the user needs to clean the entire pipe, the user should push the clamping plate simultaneously when the two positioning cylinders are pressing the drainage tube, so that the grooves on the upper and lower sides of the clamping plate can be simultaneously engaged with the corresponding pressure rod. At this time, spring A can provide an upward thrust to the pressure rod, so that it can be stably engaged with the pressure rod with the cooperation of spring A. At this time, the user can pull the connecting bracket to make the positioning cylinder roll on the drainage tube to adjust the position of the positioning cylinder. At the same time, the user should stabilize the drainage tube during the sliding process of the positioning cylinder to avoid secondary damage to the patient's wound. Attached Figure Description

[0014] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific guide tube 203 described in the above embodiments. For example, the guide tube 203 is provided with a valve to prevent the waste liquid in the drainage hose 101 from flowing out of the guide tube 203 when the plug 204 is opened.

For example, the positioning cylinder 202 is provided with a rubber ring. The purpose of this setting is to provide a buffer for the contact between the positioning cylinder 202 and the drainage hose 101, and at the same time, to increase the tightness of the connection between the positioning cylinder 202 and the drainage hose 101.

[0017] Specifically, shaft B301 is rotatably connected to its corresponding pressure rod 207, and shaft A209 is fixedly connected to its corresponding pressure rod 207. The two pressure rods 207 are respectively located on the upper and lower sides of the connecting frame 205.

[0018] Specifically, the adjustment component includes a frame 206, two rings 201 are symmetrically fixedly connected to the connecting frame 205, and the frame 206 is symmetrically fixedly connected to the upper and lower sides of the connecting frame 205. Both pressure rods 207 are slidably connected to the frame 206.

[0019] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific connecting frame 205 described in the above embodiments. For example, the connecting frame 205 is provided with a handle. The purpose of this arrangement is to make it easier for the user to hold the connecting frame 205.

[0020] Specifically, a spring A208 is fitted on the frame 206. The spring A208 is fixedly connected between the pressure rod 207 and the connecting frame 205. A retaining plate 304 is slidably connected to one side of the connecting frame 205. The retaining plate 304 has grooves on both the upper and lower sides, and the pressure rod 207 fits into the groove of the retaining plate 304.

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, the specific card plate 304 described in the above embodiments is not limited. For example, the length of the card plate 304 should meet the requirement that when the two positioning cylinders 202 press the drainage hose 101 between them, the two pressure rods 207 are directly opposite the grooves on the upper and lower sides of the card plate 304.

[0022] Specifically, the reset assembly includes a spring B302 and a pull head 303. Both ends of the shaft B301 extend through the pressure rod 207, and one end of the shaft B301 is fixedly connected to the pull head 303. The other end of the shaft B301 is fitted with a spring B302, and both ends of the spring B302 are fixedly connected to the spring B302 and the pressure rod 207, respectively.

[0023] Specifically, the other end of the drainage tube 101 is fixedly connected to the negative pressure drainage device 306, and a positioning rod 305 is fixedly connected to the negative pressure drainage device 306, with the frame 206 resting on the positioning rod 305; and the 306 can be selected from various models such as Sman Peak YX932D, Bein BES-8020AZ, and Huibo Medical HB-VB-10.

[0024] Regarding the above examples, those skilled in the art should understand that the implementation of the above technical solutions is not limited to the specific drainage tube 101 described in the above embodiments. For example, the drainage tube 101 can be detached from the connecting tube of the negative pressure drainage device 306. The purpose of this arrangement is to facilitate the removal of the drainage tube 101 from the negative pressure drainage device 306 when it stops and cannot be started, and to connect the drainage tube 101 to the syringe so that the piston rod of the syringe can be manually pulled to drain the fluid.

[0025] In this embodiment of the invention, when it is necessary to clean the deposited residue on the inner wall of the drainage tube 101, the user removes the pressure rod 207 from the positioning rod 305 and pushes the connecting bracket 205 to slide it onto the drainage tube 101. Since the inner diameter of the ring 201 is larger than the outer diameter of the drainage tube 101, the ring 201 can slide freely on the drainage tube 101 without causing deformation. At this time, the user should simultaneously press the two positioning cylinders 202, causing them to move towards each other and gradually contact the drainage tube 101 during their sliding process, thus bringing the drainage tube 101 into contact with the drainage tube 101. 1. Deformation occurs until the drainage tube 101 is compressed. At this time, the inner walls of the drainage tube 101 come into contact with each other. During this process, the pressure rod 207 synchronously compresses the spring A208 fixedly connected to it, thus putting it into a state of compression deformation. Therefore, when the user stops applying pressure to the positioning cylinder 202, the two positioning cylinders 202 can quickly rebound and reset under the action of their corresponding springs A208. When the positioning cylinder 202 compresses the drainage tube 101, the user can press the upper pull head 303 while stabilizing the distance between the two positioning cylinders 202, so that the upper positioning cylinder 202 begins to slide laterally. That is, at this time, the two The positioning cylinder 202 begins to slide relative to each other, causing the inner walls of the drainage hose 101 to rub against each other during the sliding process, thereby dislodging the deposits on them. When drainage resumes, the deposits can be sucked out of the drainage hose 101. During this process, because a spring B302 is fixedly connected between the shaft B301 and the pressure rod 207, when the user stops pressing the pull head 303, the upper positioning cylinder 202 can quickly return to its original position, so that the positioning cylinder 202 can be repeatedly pushed to slide during use, thereby increasing the cleaning effect on the deposits in the pipe. If the user needs to clean the entire pipeline, the user should... When the two positioning cylinders 202 press the drainage tube 101, the clamping plate 304 is pushed simultaneously, so that the grooves on the upper and lower sides of the clamping plate 304 are simultaneously engaged with the corresponding pressure rod 207. At this time, the spring A208 can provide an upward pushing force to the pressure rod 207. Therefore, with the cooperation of the spring A208, 307 can be stably engaged with the pressure rod 207. At this time, the user can pull the connecting frame 205 to make the positioning cylinder 202 roll on the drainage tube 101 to adjust the position of the positioning cylinder 202. At the same time, during the sliding process of the positioning cylinder 202, the user should stabilize the drainage tube 101 to avoid secondary damage to the patient's wound. When the portion of the drainage tube 101 inside the patient's body needs to be cleaned, the guide tube 203 is located on the side closest to the patient's wound. At this time, the user should remove the plug 204 at the end of the guide tube 203 and insert a medical guide wire through the guide tube 203 into the drainage tube 101 to clear the portion of the tube inside the patient's body and prevent blockage.
