AI Technical Summary
In existing negative pressure drainage bags, the length of the drainage tubes varies. Excessively long drainage tubes are often placed haphazardly and are prone to bending, which affects the smooth drainage of the fluid. In particular, when encountering debris, the drainage tubes tend to narrow, resulting in a significant reduction in drainage effectiveness.
A negative pressure drainage bag was designed, comprising a drainage bag body, a placement component, and an anti-bending mechanism. The placement component, through a combination of a support, hanging frame, sliding rod, compression plate, and compression spring, ensures the stable placement of the drainage tube. The anti-bending mechanism, through structures such as support columns, a tidying plate, inclined clamps, and bending clamps, prevents the drainage tube from bending. Buffer components and magnetic connections are used to achieve orderly placement and stable drainage of the drainage tube.
This effectively avoids bending of the drainage tube, ensuring its stability and smoothness, improving the drainage effect, reducing instability of the drainage fluid, and guaranteeing the smoothness and efficiency of drainage.

Technical Field
[0001] This utility model relates to the technical field of negative pressure drainage bags, and in particular to a negative pressure drainage bag. Background Technology
[0002] A negative pressure drainage bag is a medical device mainly used to remove liquids or gases from the body. It is widely used in many medical fields such as operating rooms, intensive care units, neurology, neurosurgery, and respiratory medicine. The negative pressure drainage bag is mainly used to collect waste fluids and sputum generated during surgery. It uses the principle of negative pressure suction to create negative pressure in the negative pressure bag, which drains the secretions of microorganisms and pathogens contained in various cavities of the human body.
[0003] In the current use of negative pressure drainage bags, the length of the drainage tubes varies. Excessively long drainage tubes are often placed haphazardly, which can easily lead to bending of the drainage tubes. This can affect the smooth drainage of the drainage fluid. When encountering debris, the bending of the drainage tube can cause the inner lumen to narrow, greatly reducing the drainage effect. Utility Model Content

[0034] like Figure 1-3 As shown, the negative pressure drainage bag includes:
[0035] The drainage bag body 2 has a negative pressure tube 3 connected to its top side, a lifting ring 4 fixedly installed in the middle of the drainage bag body 2, and a drainage tube 5 connected to its top side.
[0036] Placement component 1, wherein a drainage bag 2 is placed inside the placement component 1;
[0037] The anti-bending mechanism 6 is installed on the top side of the placement component 1 and is used to arrange and prevent bending of the drainage tube 5.
[0038] The drainage bag 2 is placed inside the placement component 1, which is then hung at the edge of the bed for stable placement. The negative pressure tube 3 connects the negative pressure device to the drainage bag 2, allowing for fluid drainage through the drainage tube 5. After the drainage tube 5 is placed, any excess drainage tube 5 is secured to the anti-bending mechanism 6, ensuring orderly placement of the drainage tube 5, preventing excess tubes, reducing the risk of bending during subsequent placement, ensuring stable drainage, and improving drainage effectiveness.
[0039] The placement assembly 1 includes a placement shell 11, a support 12, a hanging frame 13, a sliding rod 14, a pressing plate 16, and a pressing spring 15. The support 12 is fixedly connected to the bottom surface of the placement shell 11, the hanging frame 13 is fixedly connected to the right side of the top of the placement shell 11, the sliding rod 14 is slidably connected to the side surface of the hanging frame 13, the pressing plate 16 is fixedly connected to the end of the sliding rod 14, and the pressing spring 15 is fixedly connected to the side surface of the pressing plate 16.
[0040] The placement shell 11 is used to place the drainage bag 2. It is fastened to the edge of the hospital bed by the hanging frame 13. Under the action of the compression spring 15, the compression spring 15 compresses the compression plate 16 to fit against the edge of the hospital bed, which improves the overall fixation and stability of the placement shell 11 and makes it convenient to use.
[0041] The number of supports 12 is three, and the three supports 12 are distributed in a triangular shape on the bottom side of the housing 11.
[0042] The slide rod 14 has a T-shaped cross-section, and the end of the slide rod 14 penetrates the side surface of the hanging frame 13.
[0043] There are two compression springs 15, which are symmetrically distributed about the slide bar 14. The compression springs 15 are elastically connected between the compression plate 16 and the inner wall of the hanging frame 13.
[0044] The drainage bag 2 includes a bag 21, which is placed inside the housing 11. A discharge pipe 22 is fixedly connected to the bottom side of the bag 21, and a valve 23 is installed at the end of the discharge pipe 22.
[0045] The anti-bending mechanism 6 includes a support column 61, a sorting plate 65, a buffer, a connecting column 66, an inclined clamping shell 67, and a bending clamping shell 68. The top end of the support column 61 is fixedly connected to the sorting plate 65, and the bottom end of the support column 61 is slidably connected to the inner cavity opened in the placement shell 11. The buffer is installed in the inner cavity. The left side surface of the sorting plate 65 is fixedly connected to the connecting column 66, and the end of the connecting column 66 is fixedly connected to the inclined clamping shell 67 and the bending clamping shell 68.
[0046] The excess drainage tube 5 is orderly secured within the inclined clamp 67, and then sequentially secured within the bent clamp 68. This facilitates stable securing of the drainage tube 5, preventing it from becoming disordered and reducing the risk of bending. It ensures stable drainage. In case of accidental pulling, the buffer spring 62 cushions the pull on the drainage tube 5, reducing the risk of loosening. Furthermore, the drainage tube 5 slips out of the inclined clamp 67 and the bent clamp 68 under excessive force, facilitating drainage.
[0047] The number of inclined clamping shells 67 is several, and the several inclined clamping shells 67 are inclinedly arranged on the surface of the sorting plate 65. A drainage tube 5 is engaged and connected inside the inclined clamping shell 67.
[0048] The bent clamp 68 has a U-shaped cross-section, and a drainage tube 5 is fitted into the inner cavity of the bent clamp 68.
[0049] The buffer component includes a buffer spring 62, an iron plate 63, and a magnet 64. The buffer spring 62 is fixedly installed at the bottom end of the support column 61. The bottom end of the buffer spring 62 is fixedly connected to the iron plate 63. The bottom end of the iron plate 63 is magnetically connected to the magnet 64. The magnet 64 is fixedly connected in the inner cavity of the housing 11.
[0050] In use, the iron plate 63 is magnetically connected to the magnet block 64, which makes it easy to limit and fix the support column 61 and to place the drainage tube 5 on one side of the sorting plate 65. By separating the iron plate 63 from the magnet block 64, the support column 61 can be easily removed for easy disassembly and replacement.
[0051] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
[0052] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
