Description

Technical Field

[0001] This utility model relates to the field of drainage tube technology, specifically to a multi-position thoracic drainage tube. Background Technology

[0002] Drainage tubes are medical devices used in clinical surgery to drain pus, blood, and fluid accumulated between body tissues or in body cavities, preventing postoperative infection and promoting wound healing. Many types of surgical drainage tubes are used clinically; some are used for urinary catheterization, others for wounds, and they are used in the pleural cavity, brain cavity, gastrointestinal tract, and biliary tract, among others. Multi-site pleural drainage tubes are used to treat situations where there is multiple effusions or gas in the pleural cavity. These tubes are designed with multiple chambers or openings, allowing for the simultaneous drainage of fluids or gas from multiple different locations, helping doctors treat various pleural problems more effectively.

[0003] However, most existing multi-position chest drainage tubes are directly fixed to the patient with medical fixation tape during use, and the excess part of the drainage tube is exposed to the outside, making it easy to be pulled and cause injury to the patient. This makes the drainage tube less practical. Therefore, a multi-position chest drainage tube is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that most existing multi-position chest drainage tubes are directly fixed to the patient with medical fixation tape, and the excess part of the drainage tube is exposed to the outside and is easily pulled and injured by the patient, thus making the drainage tube not very practical, this utility model proposes a multi-position chest drainage tube.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the multi-position thoracic drainage tube of this utility model includes a first hose, and a through hole is provided on both the left and right sides of the lower inner surface of the first hose. A second hose passes through the two through holes, and the right end of the second hose passes through the first hose.

[0006] The left end of the second hose is set as a connecting end, the right end of the second hose is set as an insertion end, and multiple through holes are opened at the right end of the second hose. Connecting components are provided at both the top and bottom of the outer surface of the first hose.

[0007] Preferably, the connecting assembly includes connecting pads disposed at the top and bottom of the outer surface of the tubing, a buffer assembly disposed inside the connecting pad, the buffer assembly being fixedly installed with the tubing, and multiple evenly distributed medical fixation tapes being fixedly connected to both sides of the connecting pad.

[0008] Preferably, the buffer assembly includes an inner groove formed inside the connecting pad, one side of the inner groove extending to the outside of the connecting pad, a buffer block inserted inside the inner groove, a through guide groove formed inside the buffer block, a guide rod sliding through the guide groove, the guide rod being fixedly connected to the inner groove, and the buffer block being fixedly connected to the hose.

[0009] Preferably, each of the two connecting pads has a fitting groove on one side opposite to the other, the fitting groove being arc-shaped inside, and one outer surface of the hose fitting into the fitting groove.

[0010] Preferably, the opposite sides of the two connecting pads are both formed into an arc shape, and both connecting pads are made of silicone material.

[0011] Preferably, both the buffer block and the guide rod are made of sponge material.

[0012] Preferably, a label groove is provided at the center of the front surface of both connecting pads.

[0013] The advantages of this utility model are:

[0014] 1. This utility model uses a buffer component to buffer the tension of hose one and hose two. When hose one and hose two are pulled, the buffer block slides inside the inner groove. When the buffer block slides, it is guided by the sliding connection between the guide rod and the guide groove. Then, when the buffer block is squeezed, it is triggered to buffer the compression. This buffers the tension of hose one and hose two and prevents the patient from being injured after hose one and hose two are pulled.

[0015] 2. This utility model uses a flexible tube to form a multi-position drainage tube by connecting two flexible tubes through one flexible tube. The right end of the flexible tube is inserted into the patient's chest cavity for drainage, and drainage is carried out at multiple positions through multiple through holes. This allows the drainage tube to drain smoothly during use, and the position of the drainage tube is relatively fixed. Drainage from specific positions is more sufficient, the patient recovers faster, and the trauma to the patient is less, reducing the number of wounds. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 As shown, the multi-position drainage tube for the chest cavity includes a flexible tube 1. The lower inner surface of the flexible tube 1 has through holes on both the left and right sides. A flexible tube 2 passes through the two through holes, and the right end of the flexible tube 2 passes through the flexible tube 1.

[0026] The left end of the second flexible tube 2 is set as the connecting end, and the right bent end of the second flexible tube 2 is set as the insertion end. Multiple through holes are opened at the right bent end of the second flexible tube 2. Connecting components are set at both the top and bottom of the outer surface of the first flexible tube 1. In operation, the second flexible tube 2 passes through the first flexible tube 1 to form a multi-position drainage tube. The right end of the first flexible tube 1 is inserted into the patient's chest cavity for drainage. Drainage is carried out at multiple positions through multiple through holes. This ensures smooth drainage during use, and the drainage tube position is relatively fixed. Drainage from specific positions is more sufficient, the patient recovers faster, and the trauma to the patient is less, reducing the number of wounds. At the same time, the excess part of the drainage tube can be connected to the patient's body through the connecting components without causing discomfort, thus making the drainage tube highly practical.

[0027] The connecting assembly includes connecting pads 3 located on the upper and lower surfaces of the outer surface of the tubing 1. A buffer assembly is installed inside each connecting pad 3. The buffer assembly is fixedly installed to the tubing 1. Multiple evenly distributed medical fixation tapes 4 are fixedly connected to both sides of the connecting pads 3. During operation, the connecting pads 3 and the buffer assembly connect and fit the tubing 1 to the patient, securing it with the medical fixation tapes 4. Simultaneously, the connecting pads 3 allow any excess portion of the tubing 1 and tubing 2 to fit snugly against the patient's body, preventing the tubing 1 and tubing 2 from being directly fixed to the patient's skin with the medical fixation tapes 4, thus avoiding discomfort. Furthermore, the connection of the tubing 1 with the connecting pads 3 ensures it only fits against the patient's skin without being squeezed or causing discomfort. The buffer assembly functions even when the tubing 1 and tubing 2 are stretched, preventing injury to the patient.

[0028] The buffer assembly includes an inner groove 6 formed inside the connecting pad 3, with one side of the inner groove 6 extending to the outside of the connecting pad 3. A buffer block 7 is inserted into the inner groove 6, and a through guide groove 9 is formed inside the buffer block 7. A guide rod 8 slides through the guide groove 9, and the guide rod 8 is fixedly connected to the inner groove 6. The buffer block 7 is fixedly connected to the first hose 1. During operation, the buffer assembly can buffer the tension on the first hose 1 and the second hose 2. When the first hose 1 and the second hose 2 are pulled, the buffer block 7 slides inside the inner groove 6. As the buffer block 7 slides, it is guided by the sliding connection between the guide rod 8 and the guide groove 9. When the buffer block 7 is squeezed, it is triggered to buffer the compression and thus buffer the tension on the first hose 1 and the second hose 2, preventing injury to the patient after the first hose 1 and the second hose 2 are pulled. At the same time, the design of the buffer block 7 and the guide rod 8 allows the connecting pad 3 and the second hose 2 to be connected without affecting the use of the buffer assembly.

[0029] Each of the two connecting pads 3 has a fitting groove 5 on one side opposite to the other. The fitting groove 5 is arc-shaped inside. The outer surface of the tubing 1 fits into the fitting groove 5. During operation, the arc-shaped fitting groove 5 on the outer surface of the connecting pad 3 allows the connecting pad 3 to fit better with the tubing 1. At the same time, it can avoid the connection between the connecting pad 3 and the tubing 1 and the protruding part, and avoid causing discomfort to the patient.

[0030] Both connecting pads 3 have their opposite sides set in an arc shape, and both connecting pads 3 are made of silicone. During operation, setting the opposite sides of the two connecting pads 3 in an arc shape makes the exposed side of the connecting pad 3 smoother and avoids causing an unpleasant experience for the patient. At the same time, the connecting pads 3 are made of silicone, which is a material that is very suitable for skin contact, has good biocompatibility, is soft and elastic, and is not likely to cause allergies or irritation. Silicone also has good temperature resistance and chemical resistance, and can be used for a long time in medical environments.

[0031] Both the buffer block 7 and the guide rod 8 are made of sponge material. During operation, the sponge material of the buffer block 7 and the guide rod 8 makes them softer and more comfortable when attached to the patient. At the same time, the sponge material of the buffer block 7 provides better cushioning when stretched, so that the tubing 1 and tubing 2 can be better cushioned when stretched, thus avoiding greater damage to the patient.

[0032] Example 2

[0033] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, a label groove 10 is provided at the center of the front surface of both connecting pads 3. During operation, the label groove 10 provided on the front surface of the connecting pad 3 makes it easy for medical staff to attach labels, and also makes it easy for medical staff to identify and distinguish them, and can meet more usage needs.
