Description

Technical Field

[0001] This invention belongs to the field of auxiliary device technology, specifically relating to a chest tube fixation device. Background Technology

[0002] Chest tubes are a commonly used medical device in thoracic surgery. They are mainly used to drain abnormally accumulated gas or fluid from the pleural cavity to help restore lung function. Common causes include pneumothorax, hemothorax, pleural effusion, empyema, or postoperative drainage.

[0003] When inserting a chest tube, under local anesthesia, the appropriate insertion site must be selected on the patient's chest based on the substance to be drained (such as liquid or gas). For example, when draining gas, the chest tube should be inserted at the highest point of the gas flow, while when draining fluid, it should be inserted at the lowest point of fluid accumulation. Specifically, for draining gas, the insertion point is usually in the second intercostal space along the midclavicular line, and for draining fluid, it is usually in the fifth or sixth intercostal space along the midaxillary line or posterior axillary line.

[0004] During insertion, a puncture needle is first inserted into the pleural cavity at a 45-degree angle under sterile conditions. After confirming the location, the drainage tube is inserted along the direction of the puncture needle, with the end positioned at the lowest point of the effusion or the highest point of the gas. After insertion, the drainage tube is usually secured to the patient's chest skin with sutures or adhesive tape to prevent displacement or dislodgement. However, coughing can easily cause chest vibration, which may lead to slippage of the chest drainage tube. Severe slippage may necessitate reinsertion, undoubtedly increasing the patient's pain and burden. Summary of the Invention

[0005] This invention discloses a chest tube fixation device, which aims to solve the technical problem in the prior art where the chest tube is fixed by adhesive tape and sutures, but it may still slip off when coughing.

[0006] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A chest drainage tube fixation device includes a fixation box with a first fixation part that mates with a drainage tube. The first fixation part includes a first window on the fixation box that fits against the patient's skin. The first fixation part also includes a clamping part that mates with the first window. The clamping part includes several pressure pads arranged circumferentially along the first window. Each pressure pad has a first part that mates with the adhesive tape of the drainage tube and a second part that clamps the drainage tube. The first part and the second part are connected by a first adjustment device. When the first adjustment device receives vibration caused by the patient's cough, it can drive the first part to fit with the adhesive tape and cause the second part to clamp the drainage tube.

[0008] When this technology is used, the patient's chest cavity vibrates when they cough, causing it to rise and fall. This rise and fall drives the first adjustment device to move, causing the first part to press against the adhesive tape fixing the drainage tube, preventing the tape from breaking off from the patient's skin when they cough. At the same time, it also drives the second part to clamp the drainage tube. In this way, the drainage tube is clamped and fixed in both the longitudinal and transverse directions, which can prevent the chest drainage tube from falling off and ensure the drainage effect for the patient.

[0009] The first adjustment device includes a first rod disposed on a pressure pad, and the first rod is perpendicular to the human body when the fixing box contacts the human body. A second rod perpendicular to the first rod is disposed inside the pressure pad. The contact point between the first rod and the second rod is a wedge-shaped structure. The first rod can push the second rod to move closer to the drainage tube. The first adjustment device also includes a buffer plate disposed inside the pressure pad. The buffer plate is disposed on the side of the pressure pad closer to the human body. The buffer plate is rotatably connected to the second rod.

[0010] With this technical solution, a first rod and a second rod are respectively set inside the pressure pad. The first rod can receive the vibration of the chest cavity when the patient coughs. The first rod can move in the pressure pad when the chest cavity vibrates and rises. It cooperates with the wedge structure of the second rod to push the second rod towards the drainage tube and clamp the drainage tube.

[0011] At the same time, the second rod is also rotatably connected to a buffer pad. When the second rod is pushed by the first rod towards the drainage tube, it simultaneously drives the buffer plate to rotate, bringing the buffer plate into contact with the patient's skin covered with adhesive tape. This compresses and fixes the adhesive tape on the drainage tube.

[0012] Therefore, the design of the first rod, the second rod, and the buffer plate simplifies the way the drainage tube is fixed and improves the ease of use. At the same time, since the device does not have electrical or other structures, it saves energy.

[0013] The pressure pad is provided with a first groove and a second groove that respectively cooperate with the first rod and the second rod. The first groove is located near the edge of the pressure pad. The buffer plate is connected to the second rod through a rotating rod. The rotating rod is inclined and its inclination direction is upward along the second guide hole towards the first guide hole. A reset device is provided in the angle between the rotating rod and the buffer plate. The reset device is located near the first rod. The pressure pad is provided with a third groove that cooperates with the rotating rod. The bottom wall of the pressure pad is provided with a first groove that cooperates with the buffer plate.

[0014] After adopting this technical solution, the buffer plate and the second rod are connected by the rotating rod. When the second rod is pushed by the first rod to move towards the direction of the drainage tube, the second rod can synchronously drive the rotating rod to rotate. Since the second rod and the rotating rod are both set inside the pressure pad, the pressure pad can limit the second rod and the rotating rod. Therefore, when the second rod drives the rotating rod to rotate, it will synchronously drive the buffer plate to approach the direction of the human body, extend out of the first groove, and contact the human body to press the adhesive tape.

[0015] The design of the first, second, and third slide grooves increases the stability of the first and second rods during sliding, thereby increasing the stability of the device during use.

[0016] The resetting device includes a telescopic spring, with its two ends connected to a rotating rod and a buffer plate, respectively. By employing this technical solution, a telescopic spring is installed between the second rod and the buffer plate. When the patient is not coughing, the telescopic spring allows the rotating rod to slide, thereby resetting the second and first rods. This facilitates the re-fixation of the drainage tube and adhesive tape when the patient coughs again.

[0017] The buffer plate has a first elastic pad on the side closest to the human body, the first rod has an arc-shaped buffer pad on the side closest to the human body, the first elastic pad and the arc-shaped buffer pad are slidably connected, the second rod has a second elastic pad on the side closest to the drainage rod, the second elastic pad has an arc-shaped structure, and the pressure pad has a second groove on the side closest to the drainage tube to accommodate the second elastic pad.

[0018] By adopting this technical solution, a first elastic pad is set on the side of the buffer plate closest to the human body, and an arc-shaped buffer pad is set on the side of the first rod closest to the human body. This can improve the patient's comfort when the buffer plate comes into contact with the human body.

[0019] A second elastic pad with an arc-shaped structure is set on the side of the second rod that contacts the drainage tube, which can protect the drainage tube when clamped and ensure the drainage effect for the patient.

[0020] The pressure pad is detachably connected to the fixing box. The fixing box is provided with a slot that mates with the pressure pad. The fixing box is also provided with a third fixing part that mates with the pressure pad. The third fixing part includes a pressure plate. The pressure plate is connected to the fixing box via a telescopic rod. The pressure plate is located on the side of the pressure pad away from the human body.

[0021] After adopting this technical solution, the pressure pad is set to be detachably connected to the fixation box. When the adhesive tape on the patient's body is found to be loose, the pressure pad can be removed to expose the first window, and the adhesive tape and sterile gauze covering the wound can be replaced without removing the entire fixation device, which is more convenient to use.

[0022] Meanwhile, a slot and a pressure plate are provided on the fixing box. When the pressure pad is installed on the fixing box, the slot and pressure plate can improve the stability of the pressure pad during use, thereby enhancing the stability of the device during use.

[0023] The pressure pad is also provided with a cleaning part that can squeeze the drainage tube.

[0024] When using this technology, the drainage tube may become blocked due to the presence of blood clots. When the drainage tube is blocked, medical staff need to manually squeeze the drainage tube section by section to squeeze the blood clots into the drainage bottle to clean the drainage tube. This cleaning method is inconvenient because it requires manual squeezing of the drainage tube.

[0025] This device features a cleaning section on the pressure pad, and the pressure pad is detachably connected to the fixing box. This allows the pressure pad to squeeze the drainage tube when it becomes blocked, thus clearing the blockage and improving the device's practicality.

[0026] The cleaning section includes a squeezing roller disposed on the second rod, the squeezing roller being disposed on the side of the second rod near the drainage tube. The cleaning section also includes a clamping plate disposed on the pressure pad, two clamping plates being disposed inside the squeezing roller. The pressure pad is provided with a driving device for driving the clamping plates to clamp the drainage tube.

[0027] With this technical solution, a clamping plate and squeezing rollers are installed outwards along the body. When the pressure pad slides along the drainage tube, the squeezing rollers first crush the blockage in the drainage tube. The crushed blockage is then scraped by the clamping plate and scraped into the drainage bottle, thus clearing the blockage. This further improves the convenience of cleaning blocked drainage tubes.

[0028] The driving device includes a driving rod disposed on the pressure pad, the driving rod being disposed on the side of the pressure pad away from the human body, the second rod being provided with a mounting hole that mates with the driving rod, and the side of the driving rod that contacts the clamping plate having a wedge-shaped structure.

[0029] With this technical solution, the clamp can be installed simply by pressing down the drive rod when the drainage tube needs to be cleaned, thanks to the mounting hole, drive rod, and wedge-shaped structure on the pressure plate. This makes it quite convenient to use.

[0030] The fixing box is also provided with a connecting device, which includes fixing straps on both sides of the fixing box, and a second adjusting device on the fixing straps to adjust the distance between the fixing straps and the human body.

[0031] By adopting this technical solution, the size of the ring structure formed by the two fixing straps and the fixing box can be adjusted through the fixing straps to adapt to patients of different body sizes and fix different patients, thereby improving the practicality of this device.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] (1) By using the first and second parts, the adhesive tape and drainage tube can be fixed simultaneously when the patient coughs, reducing the impact of chest tremors on the stability of the drainage tube and improving the stability of the drainage tube during use.

[0034] (2) The use of a first rod, a second rod, and a buffer plate allows the device to rely on the rise and fall of the chest cavity to drive the first rod, the second rod, and the buffer plate to clamp the adhesive tape and the drainage tube respectively when subjected to chest cavity vibration, which simplifies the use of the device and saves energy.

[0035] (3) The first slide groove, the second slide groove and the third slide groove are provided to increase the stability of the first rod and the second rod when sliding, thereby increasing the stability of the device when in use.

[0036] (4) A telescopic spring is installed between the second rod and the buffer plate. When the patient is not coughing, the telescopic spring can be used to make the rotating rod slide, thereby making the second rod and the first rod reset, so that the drainage tube and adhesive tape can be fixed again when the patient coughs next time.

[0037] (5) A clamping plate and a squeezing roller are installed outwards along the body. When the pressure pad is fitted onto the drainage tube and slides along the drainage tube, the squeezing roller first squeezes and breaks up the blockage in the drainage tube. The broken blockage is then scraped by the clamping plate and scraped into the drainage bottle, thus clearing the blockage in the drainage tube. This further improves the convenience of cleaning the drainage tube blockage and the practicality of the device.

[0038] (6) A first elastic pad is set on the side of the buffer plate closest to the human body, and an arc-shaped buffer pad is set on the side of the first rod closest to the human body. This can improve the patient's comfort when the buffer plate comes into contact with the human body. Attached Figure Description

[0048] The following is combined Figures 1-4 The present invention will be described in detail below.

[0049] Example 1

[0050] A chest tube fixation device, such as Figures 1-4 As shown, the device includes a fixing box 2, which has a first fixing part that cooperates with the drainage tube. The first fixing part includes a first window 202 on the fixing box 2, which fits against the patient's skin. The first fixing part also includes a clamping part that cooperates with the first window 202. The clamping part includes several pressure pads 3 arranged circumferentially along the first window 202. Each pressure pad 3 has a first part that cooperates with the adhesive tape of the drainage tube and a second part that clamps the drainage tube. The first part and the second part are connected by a first adjusting device. When the first adjusting device receives vibration caused by the patient's cough, it can drive the first part to fit with the adhesive tape and make the second part clamp the drainage tube.

[0051] In this embodiment, the fixation box 2 is made of PVC material. PVC is transparent and lightweight, which improves patient comfort while wearing it. It is also low-cost and can be used as a disposable item to prevent cross-infection. In other embodiments, the fixation box 2 can be made of stainless steel, which is durable, corrosion-resistant, reusable, and reduces costs.

[0052] In this embodiment, the length, width and height of the fixing box 2 are 5*3*4cm, which is smaller than the width of the side of the human chest cavity, so that it can make good contact with the chest cavity and fix the drainage tube.

[0053] In this embodiment, the fixing box 2 is provided with a receiving cavity for accommodating the tightening part, such as... Figure 2 As shown.

[0054] In this embodiment, the first window 202 is a rectangular structure, which matches the shape of the drainage tube with adhesive tape attached.

The first adjustment device also includes a buffer plate 6 disposed inside the pressure pad 3. The buffer plate 6 is disposed on the side of the pressure pad 3 closer to the human body. The buffer plate 6 is rotatably connected to the second rod 5.

[0059] In this embodiment, the second rod 5 is positioned parallel to the human body. Both the first rod 4 and the second rod 5 have wedge-shaped structures that are inclined surfaces. The inclined surface of the first rod 4 slopes downwards towards the drainage tube, while the inclined surface of the second rod 5 slopes upwards towards the drainage tube.

[0060] In this embodiment, the second rod 5 is provided with a clamping block 502 that can clamp the drainage tube.

[0061] In this embodiment, both the first rod 4 and the second rod 5 are made of PVC. In other embodiments, both the first rod 4 and the second rod 5 can be made of stainless steel, which will result in smoother sliding and faster response. In other embodiments, the first rod 4 can also be electrically driven. A pressure sensor is installed at the end of the first rod 4, which is electrically connected to a controller. The controller is connected to a motor and other drive components. The controller controls the rotation of the motor, thereby controlling the vertical movement of the first rod 4, which in turn pushes the second rod 5. The drive mechanism between the first rod 4 and the motor can be a rack and pinion mechanism.

[0062] In this embodiment, the pressure pad 3 is provided with a first sliding groove 302 and a second sliding groove 303 that respectively cooperate with the first rod 4 and the second rod 5. The first sliding groove 302 is located near the edge of the pressure pad 3. The buffer plate 6 is connected to the second rod 5 through a rotating rod 601.

[0073] In this embodiment, the first elastic pad 602, the second elastic pad 504, and the arc-shaped buffer pad 401 are respectively bonded to the buffer plate 6, the second rod 5, and the first rod 4 by means of adhesion.

[0074] In this embodiment, the arc-shaped buffer pad 401 is centered on the first rod 4, with both ends bent towards the buffer plate 6.

[0075] In this embodiment, the arc-shaped structure of the second elastic pad 504 matches the diameter of the drainage tube.

[0076] In this embodiment, the pressure pad 3 is detachably connected to the fixing box 2. The fixing box 2 is provided with a slot that cooperates with the pressure pad 3. The fixing box 2 is provided with a third fixing part that cooperates with the pressure pad 3. The third fixing part includes a pressure plate 701. The pressure plate 701 is connected to the fixing box 2 through a telescopic rod 7. The pressure plate 701 is located on the side of the pressure pad 3 away from the human body.

[0077] In this embodiment, four pressure plates 701 are provided.

[0078] In this embodiment, the fixed box 2 includes a box cover 203, which is rotatably connected to the fixed box 2, and the telescopic rod 7 is set on the box cover 203 by welding.

[0082] In this embodiment, the telescopic rod 7 includes a sub-rod and a main rod. The sub-rod is sleeved within the main rod. Both ends of the sub-rod and the main rod are closed structures, and the sub-rod and the main rod are connected by a connecting spring. The connecting spring can further buffer the vibration from the chest cavity.

[0083] In this embodiment, the two ends of the connecting spring are welded to the male rod and the female rod, respectively.

[0084] In this embodiment, the fixing box 2 is also provided with a connecting device. The connecting device includes fixing straps 1 disposed on both sides of the fixing box 2. The fixing straps 1 are provided with a second adjusting device that can adjust the distance between the fixing straps 1 and the human body.

[0085] In this embodiment, the fixing strap 1 is made of polyester amide, and a cotton pad is provided on the side closest to the human body, which has good breathability and makes it more comfortable for the patient to wear.

[0086] In this embodiment, the two ends of the fixing box 2 are provided with hanging rings 201, one end of the fixing strap 1 is provided with a hook that is connected to the hanging ring 201, and the other end of the fixing strap 1 is provided with Velcro, which completes the connection with the patient's body.

[0087] The specific method of using this invention is as follows:

[0088] Reference Figures 1-4 When using this device, first fix the drainage tube to the patient's body through conventional operation, then pass the other end of the drainage tube through the first window 202 on the fixation box 2 and the through holes in the four pressure pads 3, then make the fixation box 2 contact the area near the drainage port of the patient's body, connect the two fixation straps 1, and fix the fixation box 2 to the patient's chest cavity.

[0089] During this process, the telescopic rod 7 automatically adjusts its length to ensure stable contact between the pressure pad 3 and the patient's drainage port. The pressure plate 701 of the pressure pad 3 fixes the adhesive tape that secures the drainage tube. The through-hole structure formed by the four pressure pads 3 clamps the drainage tube. When the patient coughs, the chest rises and falls, squeezing the first rod 4, causing it to slide inside the pressure pad 3. The wedge-shaped structure of the first rod 4 and the second rod 5 contacts, pushing the second rod 5 to slide closer to the drainage tube. The second elastic pad 504 connected to the second rod 5 further squeezes the drainage tube to prevent it from sliding.

[0090] At the same time, the second rod 5 slides through the rotating rod 601 to drive the buffer plate 6 to move towards the human body along the thickness direction of the pressure pad 3, and contact the adhesive tape that fixes the drainage tube, thereby fixing the adhesive tape.

[0091] This device employs a first part and a second part, which can simultaneously fix the adhesive tape and the drainage tube when the patient coughs, reducing the impact of chest tremors during coughing on the stability of the drainage tube fixation and improving the stability of the drainage tube during use.
