[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See also Figure 1-Figure 2 A preferred embodiment of the present invention is a chest closed drainage bottle fixing device 3, comprising: a box body 1 and a movable adjustment device 2.

[0029] The box body 1 has an inner cavity for accommodating a closed chest drainage bottle. The side wall of the box body 1 is provided with a through hole connecting the inner cavity with the external environment, and the through hole is provided with an internal thread. The bottom of the box body 1 is provided with an anti-skid pad. The anti-skid pad can provide sufficient friction when the ground is wet and slippery to prevent the box body 1 from slipping. Even if the box body 1 is not fixed, the anti-skid pad can also play a protective role. The anti-skid pad is a soft pad, which makes the box body 1 softer when in contact with the ground, effectively reducing bumps. At the same time, the elastic properties of the anti-skid pad can also buffer external impacts, further protecting the box body 1 and the closed chest drainage bottle inside, ensuring its stability and safety during use.

[0030] The movable adjustment device 2 includes a first pressing plate 201, a first elastic member 202, a movable plate 203, and an adjusting screw 204. The first pressing plate 201 is disposed within the inner cavity and is used to abut against the chest cavity closed drainage bottle. One end of the first elastic member 202 abuts the first pressing plate 201, and the other end of the first elastic member 202 abuts the movable plate 203, allowing the first pressing plate 201 to move toward or away from the chest cavity closed drainage bottle. An adjusting screw 204 is movably sleeved on the side of the movable plate 203 away from the first elastic member 202 and moves back and forth along the axis of the adjusting screw 204 following the adjusting screw 204. The adjusting screw 204 is threadedly connected to the through hole. The first pressing plate 201 stably presses the chest cavity closed drainage bottle to prevent it from loosening or shifting within the box body 1, ensuring a smooth drainage process. The first elastic member 202 works in conjunction with the first pressure plate 201, so that the fixing device 3 can automatically adjust according to the size of the chest closed drainage bottle, achieving adaptive fixation and meeting the use requirements of chest closed drainage bottle equipment of different specifications. If the size difference of the chest closed drainage bottle is too large or the fixing pressure is not appropriate, the distance between the movable plate 203 and the chest closed drainage bottle can be accurately adjusted by rotating the adjustment screw 204, thereby adjusting the pressure of the first pressure plate 201 on the chest closed drainage bottle. The cooperation between the first elastic member 202 and the adjustment screw 204 combines their respective adjustment advantages and significantly improves the ability to adapt to chest closed drainage bottles of different specifications. It avoids the problem of pressure being unable to adjust and the limited adaptability when using the elastic member alone, and also solves the disadvantages of frequent operation, time-consuming and labor-intensive operation caused by using the adjustment screw 204 alone. The first elastic member 202 preferably adopts a high-efficiency elastic element such as a spring to ensure that a stable and reliable elastic force is provided.

[0031] Working principle: Place the closed chest drainage bottle into the accommodation space between the first pressure plate 201 and the side wall of the box body 1. If the pressure of the first pressure plate 201 on the drainage bottle is insufficient and cannot be fixed, rotate the adjusting screw 204 clockwise to move the movable plate 203 closer to the drainage bottle until the first pressure plate 201 applies sufficient pressure to the drainage bottle, thereby achieving a firm fixation of the drainage bottle. If the pressure of the first pressure plate 201 is too great, making it difficult to place the drainage bottle, first rotate the adjusting screw 204 counterclockwise to move the movable plate 203 away from the drainage bottle, creating enough space to place the drainage bottle therein, and finally fine-tune the adjusting screw 204 to accurately adjust the position of the movable plate 203 so that the first pressure plate 201 applies appropriate pressure to the drainage bottle, ensuring a firm fixation without damaging the drainage bottle.

[0032] Obviously, the cooperation between the first elastic member 202 and the adjusting screw 204 enhances the adaptability to chest closed drainage bottles of different specifications. Precise pressure adjustment is achieved, while reducing the frequency of rotating the adjusting screw 204 when fixing and removing the chest closed drainage bottle. When the size difference of the chest closed drainage bottle is too large or the initial fixing pressure is not suitable, it is only necessary to rotate the adjusting screw 204 to accurately adjust the distance between the movable plate 203 and the drainage bottle, thereby changing the pressure applied by the first pressure plate 201 to the drainage bottle, ensuring its firm clamping and preventing loosening or displacement. In addition, the elastic force of the first elastic member 202 can automatically compensate for the gap caused by the change in the size of the drainage bottle, further improving the stability of the fixation.

[0033] The opposite side walls of the box body 1 are respectively connected to a second elastic member 5, the second elastic member 5 is located in the inner cavity, and the other end of the second elastic member 5 is connected to a second pressure plate 4. The two pressure plates are arranged opposite to each other, and the first pressure plate 201 is located between the two second pressure plates 4, and is used to cooperate with the two second pressure plates 4 to jointly form an extrusion area for accommodating and squeezing the chest cavity closed drainage bottle. The second elastic member 5 is symmetrically arranged on both sides of the box body 1, and can simultaneously squeeze and fix the two sides of the chest cavity closed drainage bottle, and stably place it in the center of the two second pressure plates 4, facing the center of the first pressure plate 201, to facilitate precise pressure fixation. The provision of two second elastic members 5 provides a larger adaptive space for the chest cavity closed drainage bottle, so that it can better adapt to drainage bottles of different sizes and enhance the stability and reliability of fixation.

[0034] The tops of the first pressing plate 201 and the second pressing plate 4 are both inclined. The inclined surface of the first pressing plate 201 is tilted directly above the first elastic member 202, while the inclined surface of the second pressing plate 4 is tilted directly above the second elastic member 5. The first pressing plate 201 and the second pressing plate 4 serve as guides. When placing a closed chest drainage bottle, there is no need to manually press the pressing plates; the drainage bottle slides naturally along the inclined surface and enters the compression area, achieving rapid positioning and fixation.

[0035] A first flexible anti-skid pad is provided on the side of the first pressing plate 201 that abuts against the closed chest drainage bottle, and a second flexible anti-skid pad is provided on the side of the second pressing plate 4 that abuts against the closed chest drainage bottle. When the first pressing plate 201 and the second pressing plate 4 apply pressure to the closed chest drainage bottle, the anti-skid pad is in close contact with the bottle body, generating a large friction force, thereby ensuring that the closed chest drainage bottle is firmly in the squeeze area. Even if the fixing device 3 is accidentally overturned, the anti-skid pad can prevent the closed chest drainage bottle from sliding from the squeeze area to the external environment, thereby minimizing the impact on the drainage tube. The flexible anti-skid pad increases friction, effectively preventing the closed chest drainage bottle from moving or falling out in the fixing device 3, thereby ensuring the safety of the drainage process.

[0036] The chest closed drainage bottle fixing device 3 also includes a handle 6, and the handle 6 includes a movable connecting rod 8 and a gripping portion. The two ends of the movable connecting rod 8 are respectively slidably engaged with the two opposite side walls of the top of the box body 1, and the gripping portion is connected to the connecting rod. This sliding connection allows the distance between the handle 6 and the top of the box body 1 to be flexibly adjusted. When placing the chest closed drainage bottle, the handle 6 can be slid away from the top of the squeezing area to facilitate the smooth placement of the chest closed drainage bottle into the box body 1. After the chest closed drainage bottle is stably placed, the handle 6 is slid back to the top of the chest closed drainage bottle, thereby further limiting the movement of the chest closed drainage bottle, preventing it from accidentally falling out of the box body 1, and enhancing the stability and safety of the fixation.

[0037] A slider is provided at the bottom of the handle 6, and a guide rail is provided at the top of the box body 1. The slider slidably engages with the guide rail and is equipped with a locking device that locks the slider to the guide rail. When the handle 6 slides over the closed chest drainage bottle, the locking device secures the handle 6, preventing it from moving, thereby enhancing safety. The locked handle 6 is more stable when lifted, preventing it from sliding during lifting and preventing the liquid in the drainage bottle from shifting, ensuring smooth and safe carrying. The locking device ensures that the handle 6 remains fixed during movement or transportation, preventing it from accidentally sliding due to external forces, further enhancing the reliability and safety of the device. A flexible fixing pad is also provided at the bottom of the handle 6. When the handle 6 slides to the compression area, the pad fits tightly against the closed chest drainage bottle below the handle 6, thereby securing it and effectively preventing the drainage bottle from shaking within the box body 1. The flexible connection design not only prevents damage to the chest closed drainage bottle caused by hard contact, but also absorbs certain vibrations through its elastic properties, further protecting the drainage bottle and ensuring a smooth drainage process.

[0038] There are two handles 6, which are arranged horizontally opposite to each other; the gripping portion of the handle 6 is provided with a guide groove 7, which forms a guide through-hole when the two guide grooves 7 are brought together. The guide through-hole is used for the drainage tube of the chest closed drainage bottle to pass through. When using a single-chamber chest closed drainage bottle, the guide grooves 7 of the two handles 6 can accurately form a guide through-hole, and the drainage tube passes through the guide through-hole, effectively preventing the drainage tube from falling over or getting entangled. When using a multi-chamber chest closed drainage bottle, the guide grooves 7 of the two handles 6 can guide the drainage tubes on both sides respectively, thereby ensuring the orderliness and smoothness of the drainage process.

[0039] The closed chest drainage bottle fixing device 3 also includes a fixing device 3, which includes a fixing rod 301, a movable rod 302, a suction cup 303 and a knob 304; the fixing rod 301 is arranged on the side wall of the box body 1, and there are multiple fixing rods 301, and multiple fixing rods 301 are relatively arranged on both sides of the box body 1; the movable rod 302 is pivotally connected to the fixing rod 301 so that the movable rod 302 can be parallel to the side wall of the box body 1 or parallel to the bottom of the box body 1; the end of the movable rod 302 away from the fixing rod 301 is connected to the suction cup 303 so that the suction cup 303 can swing with the movable rod 302 to be adsorbed on the ground, and the suction cup 303 is provided with the knob 304, and the knob 304 is used to squeeze the air in the suction cup 303 to the outside of the suction cup 303 so that the suction cup 303 is in a negative pressure state. The chest closed drainage bottle fixing device 3 is equipped with a plurality of suction cups 303, and the plurality of suction cups 303 are connected to the movable rod 302. The plurality of suction cups 303 can be lowered and adsorbed on the ground or folded close to the outer wall of the box body 1. When the fixing device 3 needs to be firmly fixed on the ground, first lower the movable rod 302 and press the suction cup 303 against the ground. Then, by turning the knob 304, the air in the suction cup 303 is squeezed out, so that a negative pressure is formed inside the suction cup 303, so that it is firmly adsorbed on the ground. The stability of the device is ensured to prevent it from shifting due to accidental collision. Multiple suction cups 303 are connected to both sides of the box body 1 through the fixed rod 301 and the movable rod 302. When multiple suction cups 303 can be adsorbed on the ground at the same time, a stronger fixing force is provided. This stable fixing method effectively prevents the patient's family members or patients from accidentally kicking the chest closed drainage bottle when walking, thereby avoiding the risk of the drainage tube falling off and ensuring the safety of the drainage process.

[0040] When the movable rod 302 is parallel to the side wall of the box body 1 , the knob 304 abuts against the side wall of the box body 1 ;

[0041] One of the side wall of the box body 1 and the knob 304 is provided with a magnet, and the other is provided with a magnetic element that engages with the magnet. The movable rod 302 can be retracted to a position parallel to the side wall of the box body 1. When the movable rod 302 is retracted, the knob 304 can fit tightly against the side wall of the box body 1. A magnet and a magnetic element are respectively installed between the side wall of the box body 1 and the knob 304, so that when the movable rod 302 is retracted, the knob 304 will be firmly attracted to the side wall of the box body 1 due to the magnetic effect. In this way, the movable rod 302 and the connected suction cup 303 can be fixed to the side wall of the box body 1. When the suction cup 303 is needed, just turn the movable rod 302 and pull out the suction cup 303. When the suction cup 303 is not in use, it will automatically be adsorbed on the side wall of the box body 1 due to the action of magnetism and will not fall off easily, thus ensuring the neatness and convenience of the device. This not only makes it easier to carry and store the device, but also ensures that the suction cup 303 can be quickly accessed when needed.

[0042] The side walls of the box body 1 are made of transparent material. The transparent side walls of the box body 1 allow medical staff to directly observe the condition of the liquid in the bottle, such as the amount, color, and properties, without having to remove the closed chest drainage bottle. This not only makes it easier to determine whether the drainage bottle needs to be replaced, but also reduces interference with the drainage process caused by frequent removal and observation, thereby improving nursing efficiency and reducing the risk of drainage tube dislocation. The transparent side walls of the box body 1 make it easy for medical staff to monitor changes in the drainage fluid at any time, detect abnormalities in a timely manner, and ensure patient safety. Without interfering with the drainage process, it provides medical staff with convenient observation conditions, which helps to adjust nursing measures in a timely manner.
