Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically a chest drainage bottle fixation device. Background Technology
[0002] Chest drainage bottles are key medical devices used to treat pneumothorax, hemothorax, or pleural effusion. They use a closed system to drain air and fluid from the pleural cavity to the outside, maintaining normal negative pressure in the pleural cavity and promoting lung re-expansion.
[0003] After suspension, the drainage bottle is always lower than the patient's chest cavity level. Gravity is used to allow the pleural effusion and air in the chest cavity to flow naturally into the bottle, avoiding backflow. Therefore, chest drainage bottles are usually used by directly suspending them on an external bracket through a fixing device, such as the chest drainage bottle fixing device proposed in patent application number "CN202320769719.6".
[0004] However, in the current technology, when the chest drainage bottle is directly hung on an external iron bracket, it is easy for the drainage bottle to tilt, shake or even tip over due to the patient turning over, coughing or external impact, which may cause retrograde infection or pneumothorax. Utility Model Content
[0005] The purpose of this invention is to provide a thoracic drainage bottle fixation device to solve the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A chest drainage bottle fixing device includes a fixing mechanism for fixing the chest drainage bottle. The fixing mechanism includes a fixing frame, and two movable clamps that can move in opposite directions are provided on one side of the fixing frame. The two movable clamps are used to clamp and fix the chest drainage bottle from both sides. A fixing plate is fixedly connected to the center of the top of the fixing frame. An arc-shaped plate is fixedly connected to one side of the fixing plate. An arc-shaped magnet is fixedly connected to the inner arc surface of the arc-shaped plate. The arc-shaped magnet is used to attract to an external iron support.
[0008] The top of the fixed plate is fixedly connected to a suspension rope, and the top of the suspension rope is provided with a positioning block. The positioning block has a through hole. One end of the suspension rope passes through the through hole and bends downward, and is fixedly connected to the surface of the positioning block, so as to form a closed space between the suspension rope and the positioning block.
[0009] Preferably, a suspension ring is fixedly connected to one side of the suspension rope, and a suspension opening is provided at the top of the suspension ring. The suspension ring is used to suspend the thoracic drainage bottle.
[0010] Preferably, the middle part of the fixed frame is provided with a movable groove, and one end of the inner wall of the movable groove is rotatably connected to a bidirectional screw. The bidirectional screw is divided in the middle, and the two ends of the thread are opposite in direction. Sliders are threaded to the opposite threads at both ends of the bidirectional screw. The two sliders and two movable clamps are fixedly connected.
[0011] Preferably, a limiting block is fixedly connected to the side of the slider away from the movable clamping plate, and the limiting block is in contact with the surface of the fixed frame to ensure the horizontal sliding of the slider.
[0012] Preferably, one end of the bidirectional screw passes through the fixing frame and is fixedly connected to a handle, the surface of which is provided with anti-slip texture.
[0013] Preferably, the bottom of the fixing frame is fixedly connected to two L-shaped auxiliary plates, which are used to help support the bottom of the chest drainage bottle.
[0014] The beneficial effects of this utility model are:
[0015] This invention suspends the chest drainage bottle on a suspension ring. The weight of the device tightens the suspension rope, ensuring it is securely suspended from the hook of the external iron bracket. When the chest drainage bottle is directly suspended from the hook, two movable clamps simultaneously hold it to one side of the fixing frame. The fixing frame is then attached to the external iron bracket via a fixing plate and an arc-shaped magnet on its back, thus securing the chest drainage bottle. This design effectively prevents the bottle from tilting or swaying due to patient turning, coughing, or external impacts, which could lead to loosening of the suspension, tipping of the chest drainage bottle, and consequently, the risk of retrograde infection or pneumothorax.

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1 and Figure 4 A chest drainage bottle fixing device includes a fixing mechanism for fixing the chest drainage bottle. The fixing mechanism includes a fixing frame 101. Two movable clamps 102 that can move towards each other are provided on one side of the fixing frame 101. The two movable clamps 102 are used to clamp and fix the chest drainage bottle from both sides. A fixing plate 2 is fixedly connected to the center of the top of the fixing frame 101. An arc plate 3 is fixedly connected to one side of the fixing plate 2. An arc magnet 4 is fixedly connected to the inner arc surface of the arc plate 3. The arc magnet 4 is used to attract to an external iron support. The surface of the external iron support is an arc surface, which is perfectly adapted to the arc magnet 4.
[0025] like Figure 1 and Figure 2 The top of the fixed plate 2 is fixedly connected to a suspension rope 5. The top of the suspension rope 5 is provided with a positioning block 6. The positioning block 6 has a through hole 601. One end of the suspension rope 5 passes through the through hole 601 and bends downward, and is fixedly connected to the surface of the positioning block 6. This is used to form a closed space between the suspension rope 5 and the positioning block 6. When the device needs to be suspended, the hook on the external iron bracket can pass through the closed space formed between the suspension rope 5 and the positioning block 6.
[0026] The device can be directly suspended to the existing iron bracket hook via the positioning block 6 and the suspension rope 5 without the need for separate modification of the existing iron bracket. It can be directly and easily installed on the existing iron bracket while also assisting in the fixation of the chest drainage bottle, making the device for positioning the chest drainage bottle more cost-effective and easier to promote and use.
[0027] like Figure 1 and Figure 2A suspension ring 7 is fixedly connected to one side of the suspension rope 5. The top of the suspension ring 7 has a suspension opening 701. The suspension ring 7 is used to suspend the chest drainage bottle. The suspension rope fixed on the chest drainage bottle can be inserted into the inside of the suspension ring 7 from the suspension opening 701 to suspend the chest drainage bottle to the suspension ring 7.
[0028] like Figure 3 and Figure 4 The middle part of the fixed frame 101 has a movable groove. One end of the inner wall of the movable groove is rotatably connected to a bidirectional screw 103. The bidirectional screw 103 is divided in the middle. The bottom of the fixed plate 2 extends to the inner side of the fixed frame 101. The middle part of the bidirectional screw 103 passes through the fixed plate 2. The threads at both ends are opposite. The opposite threads at both ends of the bidirectional screw 103 are threaded to sliders 104. The two sliders 104 and the two movable clamps 102 are fixedly connected, so that when the bidirectional screw 103 rotates, it can drive the two sliders 104 to move closer or further apart.
[0029] like Figure 3 and Figure 4 A limiting block 8 is fixedly connected to the side of the slider 104 away from the movable clamping plate 102. The limiting block 8 is attached to the surface of the fixed frame 101 to ensure the horizontal sliding of the slider 104. By using the limiting block 8 to be attached to the surface of the fixed frame 101, the slider 104 can be prevented from rotating.
[0030] like Figure 3 One end of the bidirectional screw 103 passes through the fixing frame 101 and is fixedly connected to a handle 9. The surface of the handle 9 is provided with anti-slip texture, which makes it convenient to manually rotate the handle 9 to drive the bidirectional screw 103 to rotate.
[0031] like Figure 1 and Figure 4 The bottom of the fixing frame 101 is fixedly connected to two L-shaped auxiliary plates 10. The L-shaped auxiliary plates 10 are used to help support the bottom of the chest drainage bottle. When the chest drainage bottle is clamped and fixed by the two movable clamps 102, the bottom of the chest drainage bottle is placed above the horizontal end of the L-shaped auxiliary plate 10.
[0032] The working principle of the chest drainage bottle fixation device provided by this utility model is as follows:
[0033] When the chest drainage bottle needs to be suspended on the external iron bracket for use, first move the positioning block 6 so that the hook on the external iron bracket relative to the closed space formed between the suspension rope 5 and the positioning block 6. At this time, under the action of the gravity of the device, the suspension rope 5 will be tightened, so that the suspension rope 5 is suspended on the hook of the external iron bracket in a tight state.
[0034] Then, the curved magnet 4 is used to attach to the external iron bracket to assist in the positioning of the fixing plate 2 and the fixing frame 101. Then, the hanging rope on the chest drainage bottle is passed through the hanging port 701 and hung on the hanging ring 7. Then, the chest drainage bottle is moved to the position between the two movable clamps 102 on one side of the fixing frame 101. The double-acting screw 103 is rotated counterclockwise to make the two movable clamps 102 move closer to each other. The chest drainage bottle is clamped and positioned twice to complete the suspension and positioning of the chest drainage bottle.
[0035] Conversely, rotating the bidirectional screw 103 clockwise can separate the two movable clamps 102, and then remove the suspension rope of the chest drainage bottle from the suspension ring 7. At this time, the suspended chest drainage bottle can be removed, which facilitates the free hanging or removal of the chest drainage bottle.
[0036] Compared with related technologies, the thoracic drainage bottle fixation device provided by this utility model has the following beneficial effects:
[0037] This invention suspends the chest drainage bottle on the suspension ring 7. The gravity of the device tightens the suspension rope 5, so that the suspension rope 5 is suspended in a tightly bound state on the hook of the external iron bracket. When the chest drainage bottle is directly suspended on the hook, it is simultaneously held on one side of the fixing frame 101 by two movable clamps 102. At the same time, the fixing frame 101 is attracted to the external iron bracket by the fixing plate 2 and the arc-shaped magnet 4 on its back, thereby fixing the chest drainage bottle. This, to a certain extent, avoids the drainage bottle from tilting and shaking due to the patient turning over, coughing, or external impact, which could cause the suspension to loosen, the chest drainage bottle to tip over, and thus lead to the risk of retrograde infection or pneumothorax.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
