Description

Technical Field

[0001] This utility model relates to the field of negative pressure drainage device technology, specifically a fixing device for a negative pressure drainage device. Background Technology

[0002] In the field of medical care, negative pressure drainage devices are an important medical device that is widely used. When using a negative pressure drainage device, an elastic cord is usually attached to it. Taking advantage of the elasticity of the cord, the device is suspended from the waist so that the patient can carry the drainage device while moving; or it can be suspended from bed frames, wheelchairs, or other equipment to meet the patient's needs in different scenarios.

[0003] When the patient gets up or moves, or when the equipment is subjected to slight external vibrations, the elastic rope attached to the negative pressure drainage device will sway. This swaying will cause the negative pressure drainage device to move unstably, making it prone to shaking and rotation.

[0004] When the negative pressure drainage device is shaken, the drainage tube will be subjected to a pulling force, which may cause the drainage tube to loosen or fall off. Utility Model Content

[0005] To address the aforementioned shortcomings, this utility model proposes a fixing device for a negative pressure drainage device. When the human body moves or the equipment vibrates, the force can be quickly distributed throughout the base, support plate, and connectors, thereby effectively preventing the negative pressure drainage device from shaking or shifting due to excessive local force, which could lead to the drainage tube becoming loose and falling off.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A fixing device for a negative pressure drainage device includes a support plate, a base, and connecting parts. The support plate includes a support plate and a base. The support plate is fixedly connected to the side wall of the base. The bottom of the base is provided with multiple locking parts. The locking parts are movably inserted through the bottom of the base and hooked to the bottom wall of the base. The base is detachably installed on the base through the locking parts. The top of the base has an upward-opening placement groove for placing the negative pressure drainage device.

[0008] The support plate is surrounded by the connector, which is used to detachably hang the support plate on a person or equipment.

[0009] The bottom of the base is provided with multiple slots, which vertically penetrate the top and bottom walls of the base, and each slot corresponds to a slotting component.

[0010] The locking component includes a connecting part and an abutting part. The top of the connecting part is fixedly connected to the bottom of the base, and the bottom of the connecting part is connected to the abutting part. The connecting part passes through the locking groove, and the abutting part abuts against the bottom wall of the base.

[0011] The slot includes a wide slot area and a narrow slot area. The wide slot area and the narrow slot area are interconnected and have an L-shaped structure. Multiple narrow slot areas are disposed on the left side of the corresponding wide slot area. The wide slot area is used for the connecting part and the abutting part to pass through the base. The narrow slot area is slidably engaged with the connecting part.

[0012] The bottom of the base is inlaid with a first magnetic element, and the bottom of the base is inlaid with a second magnetic element. The first magnetic element and the second magnetic element attract each other.

[0013] The side wall of the base is provided with a vertical observation port, which is connected to the placement groove. The observation port is used to observe the internal condition of the hydraulic drainer.

[0014] The base is provided with a limiting ring, and the limiting ring is provided with a notch in the wide groove area, the notch allowing the abutting part to move through the slot;

[0015] The outer wall of the base abuts against the inner wall of the limiting ring.

[0016] The base is provided with multiple connecting reinforcing ribs, which horizontally connect the limiting ring and the side wall of the base.

[0017] The support plate also includes a connecting plate, which has a herringbone-shaped structure and is used to connect the support plate and the base.

[0018] The support plate is either an arc plate or a straight plate.

[0019] The connector is a strap or Velcro.

[0020] Multiple connectors located on the same side are provided, and the multiple connectors on the same side are spaced apart.

[0021] The technical solution of this utility model can include the following beneficial effects:

[0022] 1. When the human body moves or the equipment vibrates, the force can be quickly distributed to the entire base, support plate and connecting parts, thereby effectively avoiding the problem of the negative pressure drainage device shaking or shifting due to excessive local force, which could lead to the drainage tube becoming loose and falling off.

[0023] 2. During installation, the connecting part and the abutment part are vertically inserted into the base from the wide slot area. Then, by rotating the base to the left, the connecting part enters the narrow slot area. Because the width of the narrow slot area is smaller than that of the wide slot area, the abutment part cannot pass through the base from the narrow slot area, thus preventing the base from easily detaching from the slot. Next, the abutment part of the locking member abuts against the bottom wall of the base, further enhancing the stability of the connection. The friction between the abutment part and the bottom wall prevents the connecting part from moving freely within the slot, thereby preventing loosening between the base and the base.

Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The following is combined with Figures 1 to 5 This describes a fixing device for a negative pressure drainage device according to an embodiment of the present invention.

[0035] A fixing device for a negative pressure drainage device includes a support plate 1, a base 2, and a connector 3. The support plate 1 includes a support plate 11 and a base 12. The support plate 11 is fixedly connected to the side wall of the base 12. The bottom of the base 2 is provided with a plurality of locking members 21. The locking members 21 are movably inserted through the bottom of the base 12 and hooked to the bottom wall of the base 12. The base 2 is detachably installed on the base 12 through the locking members 21. The top of the base 2 is provided with an upward-opening placement groove 22 for placing the negative pressure drainage device.

[0036] The support plate 11 is surrounded by the connector 3, which is used to detachably hang the support plate 1 on a person or equipment.

[0037] The upward-facing placement slot 22 at the top of the base 2 provides a dedicated, shape-fitting space for the negative pressure drainage device. After the negative pressure drainage device is placed in the placement slot 22, the slot wall provides some restraint and support, limiting the free rotation of the negative pressure drainage device in the horizontal direction, thereby reducing the possibility of the negative pressure drainage device twisting itself.

[0038] Multiple locking components 21 are movably inserted through the bottom of the base 12 and hooked onto the bottom wall of the base 12, so that the base support 2 will not easily shake or shift on the base 12, further preventing the negative pressure drainage device from twisting due to the shaking of the base support 2.

[0039] It is worth noting that the connector 3 allows the support plate 1 to be detachably hung on the human body or equipment. This distributed fixing method enables the support plate 1 to be subjected to uniform fixing forces in multiple directions, enhancing the overall stability of the device. At the same time, the support plate 11 is fixedly connected to the side wall of the base 12, forming a stable overall structure.

[0040] The connector 3 hangs the support plate 1 on the human body or equipment. When the human body moves or the equipment vibrates, the force can be quickly distributed to the entire base 12, support plate 11 and connector 3, thereby effectively avoiding the problem of the negative pressure drainage device shaking or shifting due to excessive local force, which could cause the drainage tube to loosen and fall off.

[0041] The bottom of the base 12 is provided with a plurality of slots 121, which vertically penetrate the top and bottom walls of the base 12. The plurality of slots 121 correspond one-to-one with the plurality of locking members 21.

[0042] The locking component 21 includes a connecting part 211 and an abutting part 212. The top of the connecting part 211 is fixedly connected to the bottom of the base 2, and the bottom of the connecting part 211 is connected to the abutting part 212. The connecting part 211 passes through the locking groove 121, and the abutting part 212 abuts against the bottom wall of the base 12.

[0043] The slot 121 includes a wide slot area 122 and a narrow slot area 123. The wide slot area 122 and the narrow slot area 123 are interconnected and have an L-shaped structure. Multiple narrow slot areas 123 are disposed on the left side of the corresponding wide slot area 122. The wide slot area 122 is used for the connecting part 211 and the abutting part 212 to pass through the base 12. The narrow slot area 123 is slidably engaged with the connecting part 211.

[0044] When installing the base bracket 2, simply align the locking piece 21 with the corresponding slot 121 and insert it to quickly complete the initial positioning, which greatly improves the installation efficiency.

[0045] Furthermore, the slot 121 includes a wide slot area 122 and a narrow slot area 123, with multiple narrow slot areas 123 located to the left of the corresponding wide slot area 122. Therefore, during installation, the connecting part 211 and the abutting part 212 are vertically inserted into the base 12 from the wide slot area 122, and then the base support 2 is rotated to the left to allow the connecting part 211 to enter the narrow slot area 123. Since the width of the narrow slot area 123 is smaller than that of the wide slot area 122, the abutting part 212 cannot pass through the narrow slot area 123 to exit the base 12, thus preventing the base 12 from easily detaching from the slot 121. Next, the abutting part 212 of the locking member 21 abuts against the bottom wall of the base 12, further enhancing the stability of the connection. The friction between the abutting part 212 and the bottom wall prevents the connecting part 211 from moving freely within the slot 121, thereby preventing loosening between the base support 2 and the base 12. Even under prolonged use or frequent movement, the connection between the base 2 and the base 12 can be kept tight and reliable, effectively preventing the base 2 from falling off the base 12 due to accidental collisions or vibrations during use, thus improving the safety of the device.

[0046] It is worth noting that by rotating the base 2 in the opposite direction, the base 2 rotates at a certain angle, causing the connecting part 211 to return from the narrow groove area 123 to the wide groove area 122. Then, by lifting the base 2 upward, the locking piece 21 can be pulled out from the locking groove 121, realizing the quick separation of the base 2 from the base 12. This makes it convenient for the user to replace and clean the base 2.

[0047] The bottom of the base 12 is inlaid with a first magnetic element, and the bottom of the base 2 is inlaid with a second magnetic element. The first magnetic element and the second magnetic element attract each other.

[0048] When installing the base 2, the mutual attraction between the first and second magnetic components can achieve rapid positioning. When the locking component 21 extends into the slot 121, the magnetic force will automatically guide the base 2 to rotate in the correct direction, so that the locking component 21 is quickly positioned in the narrow slot area 123, thereby abutting the abutting part against the bottom wall of the base 12, which greatly improves the installation efficiency.

[0049] Moreover, the first magnetic component and the second magnetic component attract each other, making the base 2 fit more tightly against the base 12, further reducing the shaking or displacement of the base 2 caused by external forces during use.

[0050] The side wall of the base 2 is provided with a vertical observation port 24, which is connected to the placement groove 22. The observation port 24 is used to observe the internal condition of the hydraulic drainer.

[0051] Staff only need to confirm the location of the drainage device through observation port 24, and then quickly reach into the corresponding position to directly retrieve the negative pressure drainage device, which greatly simplifies the operation process and improves work efficiency.

[0052] The vertical observation port 24 on the side wall of the base 2 is connected to the placement slot 22. Medical staff can directly observe the color, nature and amount of drainage fluid through the observation port 24 without removing the negative pressure drainage device from the placement slot 22.

[0053] Furthermore, the base 2 in this solution can be made of transparent plastic. The transparent plastic material makes the base 2 completely transparent, allowing medical personnel at a distance to observe the negative pressure drainage device placed inside the base 2 from multiple angles and from all directions. This not only allows observation of routine conditions such as the drainage fluid level and color changes, but also provides a clearer view of any abnormalities inside the drainage device, such as air bubbles or sediment, providing more comprehensive information for medical diagnosis and treatment.

[0054] The base 12 is provided with a limiting ring 124, and the limiting ring 124 is provided with a notch in the wide groove area 122, the notch allowing the abutting part 212 to move through the slot 121.

[0055] The outer wall of the base 2 abuts against the inner wall of the limiting ring 124.

[0056] The contact between the limiting ring 124 and the outer wall of the base 2 can distribute the force. When the base 2 is subjected to a vertical force, the limiting ring 124 can transfer part of the force to the base 12, reducing the pressure on the locking member 21 and the connecting structure of the slot 121, reducing the risk of damage to these components due to long-term stress, and extending the service life of the device.

[0057] The base 12 is provided with a plurality of connecting reinforcing ribs 125, which are horizontally connected to the limiting ring 124 and the side wall of the base 12.

[0058] The support plate 1 also includes a connecting plate 13, which has a herringbone-shaped structure and is used to connect the support plate 11 and the base 12.

[0059] The connecting reinforcing rib 125 horizontally connects the limiting ring 124 and the side wall of the base 12, significantly enhancing the overall strength of the base 12, making it less prone to deformation or damage when bearing the weight of the negative pressure drainage device and possible external forces.

[0060] In addition, the herringbone-shaped structure itself has good mechanical properties, which further enhances the overall strength and stability of the support plate 1 and extends the service life of the fixing device in this solution.

[0061] The support plate 11 can be an arc-shaped plate or a straight plate. It is worth noting that the arc-shaped support plate 11 conforms to the curves of the human body, evenly distributing the pressure of the drainage device on the body. The arc-shaped support plate 11 can better adapt to the movement trajectory of the human body, stably fixing the negative pressure drainage device in a suitable position, thereby reducing the possibility of the drainage device rotating due to human activity and loosening of the drainage tube.

[0062] Bed frames, wheelchairs and other equipment usually have a relatively regular planar structure. The straight support plate 11 can fit tightly against the surface of these devices, providing reliable support and fixation, preventing the support plate 1 from rotating on the device, and avoiding the situation where the connection between the drainage tube and the human body shakes due to the rotation of the fixing device.

[0063] The connector 3 is either a strap or Velcro. Both straps and Velcro have the advantages of being reusable, easy to install and remove, and convenient to operate. Therefore, medical staff or patients can easily connect and disconnect the fixation device from bed frames, wheelchairs, or other equipment or the body.

[0064] Multiple connectors 3 are provided on the same side, and these connectors 3 are spaced apart. For objects with irregular surfaces, such as bed frames and wheelchair components of various shapes, multiple spaced connectors 3 can better adapt to their shape changes. Each connector 3 can be adjusted and fitted according to the local features of the object's surface, ensuring close contact between the fixing device and the object being fixed, and improving the adaptability of the fixation.

[0065] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
