Description

Technical Field

[0001] This utility model relates to the field of clinical nursing facilities technology, and in particular to an adjustable height drainage bag bed rail fixing structure. Background Technology

[0002] In clinical nursing, postoperative patients often need to wear drainage bags to drain accumulated fluid or secretions. Traditional drainage bag fixation methods usually rely on hooks pre-installed at the bottom of the bed. However, these hooks are fixed in position and too low, and their position cannot be flexibly adjusted according to changes in patient position or nursing needs. This can easily lead to pressure, backflow, or traction on the drainage tube, increasing the risk of infection. Some medical institutions have tried using adhesive hooks or detachable hooks to fix the drainage bag to the bed rails, but the adhesion is easily affected by factors such as environmental humidity and repeated use, and lacks mechanical optimization design, making it unable to withstand fluctuations in the weight of the drainage bag, resulting in a high risk of dislodgement. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable height drainage bag bed rail fixing structure, which achieves arbitrary height fixing on the bed rail vertical bar through a simple structure and enhances the anti-slip ability.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an adjustable height drainage bag bed rail fixing structure, comprising:

[0005] The clamping device includes a fixing part for contacting a vertical rod and a suspension part for suspending a drainage bag, wherein the outer side of the fixing part is an inclined surface and the suspension part is hinged to the bottom end of the inclined surface.

[0006] Cable ties are used to secure the clamping device to the vertical bar, and the cable ties pass over the vertical bar and the suspension part and remain securely fastened.

[0007] When the drainage bag is suspended on the suspension part, the suspension part generates a lever effect under the action of gravity, causing the bottom end of the suspension part to press against the fixing part, thereby causing the inner side of the fixing part to press against the vertical rod to form friction, thus fixing the position of the clamping device on the vertical rod.

[0008] Preferably, the bottom end of the suspension part is hinged to the bottom end of the fixing part, and the upper end of the suspension part extends upward to a length exceeding the outer side length of the fixing part.

[0009] More preferably, the inner side of the fixing part is also connected to a reinforcing part for increasing the friction contact surface.

[0010] More preferably, the cable tie is a plastic cable tie.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Through the unique design of the suspension part hinged to the bottom of the inclined surface of the fixing part, the weight of the drainage bag is directly converted into the clamping force of the bottom of the suspension part against the fixing part, and further drives the inner side of the fixing part to form a self-locking frictional contact with the vertical rod. This mechanical transmission path achieves the effect that the greater the load, the stronger the friction, which can resist the risk of slippage caused by the weight fluctuation of the drainage bag.

[0013] 2. The tightening effect of the cable ties only needs to maintain the basic connection between the clamping device and the vertical bar, while the actual fixing force mainly relies on the leverage effect of the suspension part. This allows medical staff to quickly adjust the height by simply applying pressure along the vertical bar or lifting the clamping device without repeatedly tightening or loosening the cable ties, adapting to changes in the patient's sitting or lying position or the needs of nursing operations.

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] It should be noted in advance that, in this utility model, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, in this utility model, unless otherwise explicitly specified and limited, "on" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.

[0021] like Figure 1 and Figure 2 As shown, an adjustable-height drainage bag bed rail fixing structure includes:

[0022] The clamping device includes a fixing part 2a for contacting the vertical rod 1 and a suspension part 2b for suspending the drainage bag 3. The outer side of the fixing part 2a is an inclined surface, and the suspension part 2b is hinged to the bottom end of the inclined surface.

[0023] Cable tie 4 is used to bind the clamping device to the vertical rod 1. The cable tie 4 passes around the vertical rod 1 and the suspension part 2b and remains tightly bound.

[0024] When the drainage bag 3 is suspended on the suspension part 2b, the suspension part 2b is subjected to gravity and generates a lever effect, causing the bottom end of the suspension part 2b to press against the fixing part 2a, thereby causing the inner side of the fixing part 2a to press against the vertical rod 1 to form friction, thereby fixing the position of the clamping device on the vertical rod 1.

[0025] In the above structure, the bottom end of the suspension part 2b is hinged to the bottom end of the fixing part 2a, and the upper end of the suspension part 2b extends upwards to a length exceeding the outer surface length of the fixing part 2a. This facilitates the formation of a lever system with the contact point between the cable tie 4 and the suspension part 2b as the fulcrum. When the weight of the drainage bag is applied to the upper end of the suspension part, the pressure on the bottom end of the fixing part is amplified through the lever ratio, thereby significantly enhancing the normal pressure and friction between the fixing part 2a and the vertical rod 1. Simultaneously, the extra-long extension of the suspension part further expands the lever arm, allowing the clamping device to adapt to vertical rods of different diameters. During height adjustment, only a small frictional resistance needs to be overcome to achieve sliding displacement, balancing clamping stability and ease of operation. Thus, during clinical nursing, the position of the fixing structure can be moved according to the length of the drainage bag and the corresponding treatment requirements.

[0026] Preferably, the inner surface of the fixing part 2a is further connected to a reinforcing part 2c for increasing the friction contact surface, and the reinforcing part 2c is connected to the upper end of the inner surface of the fixing part 2a. By locally increasing the contact area and normal pressure, the stability of the clamping device against slippage is significantly improved, and wear of the contact surface caused by local stress concentration can also be avoided.

[0027] Furthermore, the cable tie 4 in this embodiment is a plastic cable tie. In actual use, disposable plastic cable ties can be used directly, resulting in extremely low cost. Moreover, the clamping device in this embodiment can also be implemented using existing fishtail clips, making it convenient to combine and inexpensive.

[0028] It should be noted that those skilled in the art should know that in specific clinical use, drainage bags usually need to be replaced after containing about 300ml of fluid. Therefore, the weight of the drainage bag can be controlled to provide sufficient frictional force for the clamping device without causing it to slip off.

[0029] The adjustable height drainage bag bed rail fixing structure provided in the above embodiment achieves adjustable height fixing of the drainage bag 3 on the bed vertical bar through the combination design of clamping device and cable tie 4. Its core principle is based on the synergistic effect of mechanical self-locking and leverage effect, and adopts standardized components (such as fish tail clips and plastic cable ties) to adapt to vertical bars of different diameters, avoiding wear problems caused by stress concentration. While ensuring reliability, it reduces production costs and is suitable for rapid clinical deployment and single-use scenarios.

[0030] To facilitate understanding by those skilled in the art of the improvements of this utility model compared to the prior art, some of the accompanying drawings and descriptions of this utility model have been simplified. The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
