[0002] Surgical drainage is an important medical procedure used to remove fluids (including blood, pus, inflammatory exudate, bile, secretions, etc.) accumulated in body cavities, joints, organs, or tissues from their original location and drain them out of the body to prevent accumulation in body cavities or surgical fields and subsequent harm to the human body. With the development of surgical drainage techniques, the medical field has increasingly adopted active drainage methods, namely negative pressure drainage. Negative pressure drainage uses an external negative pressure source to create negative pressure, drawing out the fluid that needs to be drained. It is increasingly widely used in general surgery, orthopedics, burn surgery, and other fields.

[0003] Negative pressure drainage bottles are essential medical devices for negative pressure drainage. The top of the bottle has two interfaces that connect to the inside of the bottle: one for connecting the drainage tube and the other for connecting the negative pressure source. Their function is to collect the fluid to be drained, making them indispensable medical devices for negative pressure drainage. However, existing negative pressure drainage bottles and negative pressure devices are separate, taking up a lot of space and being inconvenient to use when used together. Utility Model Content

Detailed Implementation

[0031] The following is combined Figures 1-9 This utility model will be described in detail.

[0032] A drainage bottle device includes a drainage bottle body 10. The internal cavity of the drainage bottle body 10 forms a liquid storage chamber. The drainage bottle body 10 is also provided with a drainage interface 201 and a negative pressure interface 202, which are used to connect an external drainage tube and a negative pressure device 203, respectively. The drainage interface 201 is connected to the liquid storage chamber, and the negative pressure interface 202 is connected to a first vent pipe 301 located in the liquid storage chamber. At least two second vent pipes extend outward from the side of the first vent pipe 301 in its radial direction. At least two opposing first fixing plates 601 are pivotally connected to the outside of the drainage bottle body 10. The space between each first fixing plate 601 forms a mounting position for installing the negative pressure device 203. The first fixing plates 601 fix the negative pressure device 203 by a connecting device.

[0033] In this embodiment, two first fixing plates 601 are pivotally connected to the outer side of the drainage bottle body 10, and two opposing second fixing plates 602 are also fixedly installed on the outer side of the drainage bottle body 10. Specifically, the two first fixing plates 601 are respectively located at the left and right ends of the outer side of the drainage bottle body 10, and the two first fixing plates 601 can be flipped left and right. The two opposing second fixing plates 602 are respectively located at the upper and lower ends of the outer side of the drainage bottle body 10. In use, the two first fixing plates 601 are opened to the side to expose the installation position, and then the negative pressure device 203 is inserted, so that the upper and lower ends of the negative pressure device 203 abut against the sides of the two second fixing plates 602 that are close to each other. Then the two first fixing plates 601 are flipped back and fixed by the connecting device. Alternatively, the positions of the two second fixing plates 602 can be replaced with flippable first fixing plates 601, so that a total of four first fixing plates 601 are provided in the top, bottom, left, and right.

[0034] In this embodiment, the connecting device is a buckle 603 provided on each of the first fixing plates 601, and the negative pressure device 203 is provided with a buckle groove adapted to the buckle 603.

[0035] In this embodiment, the connecting device further includes fixing straps (not shown in the figure) disposed on each of the first fixing plates 601, and the fixing straps are detachably connected to each other. Specifically, the fixing straps are detachably connected to each other by Velcro, buckles or magnetic attraction. The fixing straps are provided so that after the negative pressure device 203 is installed, the two first fixing plates 601 are fixed, restricting their free rotation and clamping and fixing the negative pressure device 203.

[0036] In this embodiment, the end of the first vent pipe 301 near the negative pressure interface 202 is provided with antibacterial and liquid-resistant breathable packing (not shown in the figure). In addition to antibacterial and liquid-resistant breathable packing, a similar waterproof and breathable membrane 304 can also be provided, with each second vent pipe opening provided with a waterproof and breathable membrane 304, or with a waterproof and breathable membrane 304 provided inside the pipe leading from each second vent pipe opening to the negative pressure device 203.

[0037] In this embodiment, the drainage bottle body 10 includes a front shell 102 and a rear shell 103 that are sealed together. After the front shell 102 and the rear shell 103 are connected, their internal chambers form a liquid storage chamber. The drainage port 201 is located at the top of the front shell 102 or the rear shell 103, and the negative pressure port 202 is located at the top of the front shell 102 or the rear shell 103. Specifically, the drainage port 201 is located at the top of the front shell 102, and the negative pressure port 202 is located at the top of the rear shell 103.

[0038] In this embodiment, a sealing sheet 50 is provided on the side of the rear shell 103 away from the front shell 102, and the sealing sheet 50 covers the back of the first vent pipe and each of the second vent pipes.

[0039] In this embodiment, the outer surface of the front shell 102 is provided with a liquid level scale 70.

[0040] In this embodiment, a lifting lug 80 is provided on the top of the front shell 102 or the rear shell 103. Specifically, the lifting lug 80 is provided on the top of the rear shell 103.

[0041] In this embodiment, a negative pressure connecting pipe 40 is also included, and the negative pressure interface 202 is connected to the negative pressure device 203 through the negative pressure connecting pipe 40.

[0042] In this embodiment, the lengths of the second ventilation tubes are different, and the openings of the second ventilation tubes are located at least partially in the upper and lower layers of the storage chamber. The arrangement of the first ventilation tube 301 and multiple second ventilation tubes ensures that when the drainage bottle, which is not full of exudate, tipes over, at least one second ventilation tube can connect the storage chamber and the negative pressure device 203 to conduct negative pressure, keeping the bottle under negative pressure and preventing interruption of drainage due to tipping. The waterproof and breathable membrane 304 prevents wound exudate from entering the negative pressure device 203 through the corresponding pipe, avoiding contamination or damage to the negative pressure device 203. The drainage bottle body 10 is made of a transparent or semi-transparent material, facilitating observation of the internal drainage. Specific materials are referenced in existing technology and will not be detailed here. The composition and principle of the waterproof and breathable membrane 304 are existing technologies and will not be detailed here. The waterproof and breathable membrane 304 is located at the opening of the second ventilation tube.

[0043] The negative pressure interface 202 is connected to the first vent pipe 301 located in the liquid storage cavity, which includes two cases: one is that the first vent pipe 301 is located on the wall of the liquid storage cavity (i.e., the front shell 102 or the rear shell 103 below); the other is that the first vent pipe 301 is located between the front shell 102 and the rear shell 103, such as in the middle of the liquid storage cavity. In this case, the side of the first vent pipe 301 extends at least one second vent pipe along its radial direction towards the front shell 102 and the rear shell 103 respectively.

[0044] In this embodiment, the drainage bottle body 10 includes a front shell 102 and a rear shell 103 that are sealed together. One of the front shell 102 or the rear shell 103 is provided with a first vent pipe 301 along its own height direction. At least two second vent pipes extend from the side of the first vent pipe 301 in a direction close to the other. Specifically, the drainage interface 201 is located at the top of the front shell 102, and the negative pressure interface 202 is located at the top of the rear shell 103. The cavity formed by the front shell 102 and the rear shell 103 is the liquid storage cavity. The sealing connection between the front shell 102 and the rear shell 103 is based on existing technology, such as welding or fastening, and a sealing ring may be added. The first vent pipe 301 is located on the side of the rear shell 103 close to the front shell 102. The shape of the opening of the second vent pipe can be square, circular, or other polygonal, and the relationship between the second vent pipe and the horizontal plane can be parallel, inclined, or perpendicular to the horizontal plane.

[0045] In this embodiment, the length of at least one second vent pipe is 1 / 10 to 1 / 5 of the distance between the inner walls of the front shell 102 and the rear shell 103; simultaneously, the length of at least one other second vent pipe is 4 / 5 to 9 / 10 of the distance between the inner walls of the front shell 102 and the rear shell 103. Specifically, as shown... Figures 1-2 , Figures 5-7 As shown, the lengths and depths of the two second ventilation tubes are different. In this embodiment, the second ventilation tube that is located higher and has a longer length is called the high-position second ventilation tube 302, and the other second ventilation tube that is located lower and has a shorter length is called the low-position second ventilation tube 303.

[0046] like Figure 6 (The wavy lines in each diagram represent the liquid level.) When the drainage bottle body 10 tilts forward and the front shell 102 is pressed down by the rear shell 103 and the negative pressure device 203, the liquid level in the drainage bottle overflows the opening of the high-level second vent pipe 302, but does not overflow the opening of the low-level second vent pipe 303. Therefore, the liquid storage chamber and the external negative pressure device 203 can be connected through the opening of the low-level second vent pipe 303 for negative pressure conduction; Figure 7When the body of the drainage bottle 10 tilts backward and the negative pressure device 203 is pressed down by the front shell 102 and the rear shell 103, the liquid level in the drainage bottle overflows the opening of the lower second vent pipe 303, but does not overflow the opening of the higher second vent pipe 302. Therefore, the liquid storage chamber and the external negative pressure device 203 can be connected through the opening of the higher second vent pipe 302 to conduct negative pressure.

[0047] Considering the possibility of tipping when the liquid level is high, the length of the second vent pipe can be set to be longer or shorter, depending on the usage requirements.

[0048] In this embodiment, the distance between at least a portion of the opening of at least one second vent pipe and the top wall of the liquid storage chamber is 1 / 20 to 1 / 10 of the distance between the top and bottom walls of the liquid storage chamber; at the same time, the distance between at least a portion of the opening of at least one second vent pipe and the bottom wall of the liquid storage chamber is 1 / 20 to 1 / 10 of the distance between the top and bottom walls of the liquid storage chamber.

[0049] Specifically, such as Figure 3 As shown, the distance between the highest point of the inlet of the high-position second vent pipe 302 and the top wall of the liquid storage chamber is 1 / 20 to 1 / 10 of the distance between the top and bottom walls of the liquid storage chamber, and the distance between the lowest point of the inlet of the low-position second vent pipe 303 and the bottom wall of the liquid storage chamber is 1 / 20 to 1 / 10 of the distance between the top and bottom walls of the liquid storage chamber. For example, if the distance between the top and bottom walls of the liquid storage chamber (i.e., the height of the drainage bottle body 10 after subtracting the thickness of the upper and lower shells) is 15cm, then the distance between the highest point of the inlet of the high-position second vent pipe 302 and the top wall of the liquid storage chamber is 0.75cm-1.5cm, and the distance between the lowest point of the inlet of the low-position second vent pipe 303 and the bottom wall of the liquid storage chamber is 0.75cm-1.5cm. This arrangement ensures that when the drainage bottle body 10 is placed upright on a flat surface, as... Figure 8 As shown, the liquid level in the drainage bottle completely overflows the opening of the lower second vent pipe 303, but does not completely overflow the opening of the higher second vent pipe 302. Therefore, the liquid storage chamber and the external negative pressure device 203 can be connected through the opening of the higher second vent pipe 302 for negative pressure conduction. When the drainage bottle body 10 is tilted and forced to be placed upside down, as... Figure 9 As shown, the liquid level in the drainage bottle completely overflows the opening of the high-level second vent pipe 302, but not completely overflows the opening of the low-level second vent pipe 303. Therefore, the liquid storage chamber and the external negative pressure device 203 can be connected through the opening of the low-level second vent pipe 303 for negative pressure conduction. Considering the possibility of tipping when the liquid level is very high, the distance between at least part of the opening of the second vent pipe and the top or bottom wall of the liquid storage chamber can be set to be shorter, depending on the usage requirements.

[0050] In this embodiment, the distance between at least a portion of the opening of at least one second vent pipe and the left end of the liquid storage chamber is 1 / 10 to 1 / 5 of the width of the front shell 102 or the rear shell 103; simultaneously, the distance between at least a portion of the opening of at least one other second vent pipe and the right end of the liquid storage chamber is 1 / 10 to 1 / 5 of the width of the front shell 102 or the rear shell 103. Specifically, as shown... Figure 3 As shown, the distance between the leftmost end of the high-position second vent pipe 302 and the left end of the liquid storage chamber is 1 / 10 to 1 / 5 of the width of the front shell 102 or the rear shell 103, and the distance between the rightmost end of the low-position second vent pipe 303 and the right end of the liquid storage chamber is 1 / 10 to 1 / 5 of the width of the front shell 102 or the rear shell 103. This ensures that when the drainage bottle body 10 tilts to the left or right, at least one vent pipe opening is not completely submerged by liquid. Considering the possibility of tipping when the liquid level is high, the distance between at least a portion of the second vent pipe opening and the left or right end of the liquid storage chamber can be set even shorter, depending on the usage requirements.

[0051] The working principle of the drainage bottle device proposed in this utility model is as follows:

[0052] In use, the drainage port 201 of the drainage bottle body 10 is connected to the external drainage tube, and the negative pressure port 202 is connected to the external negative pressure device 203 through the negative pressure connecting pipe 40. The negative pressure device 203 starts working to put the liquid storage chamber in a negative pressure state, and the liquid to be drained is introduced into the liquid storage chamber through the drainage tube. In the event of tipping, at least one second vent pipe can connect the liquid storage chamber and the negative pressure device 203 to conduct negative pressure, so that the bottle is always in a negative pressure state and the drainage is not interrupted due to tipping.

[0053] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it, and they cannot be used to limit the protection scope of this utility model.
