Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a drainage tube pressurization device. Background Technology
[0002] Decompression drainage is a widely used treatment method in clinical practice. By placing a drainage device at the site where drainage is needed, the accumulated fluid (such as blood, pus, exudate, etc.) or gas in the body can be drained out through the drainage tube using the principles of gravity and negative pressure suction. This reduces local pressure, improves local blood circulation and tissue metabolism, and prevents complications such as infection and tissue damage caused by the accumulation of fluid or gas.
[0003] Nurses routinely use drainage devices consisting of a combination of drainage tubes and drainage bottles. In practice, considering the different conditions of each patient, maintaining the patency of the drainage tube is crucial to prevent postoperative complications such as infection and delayed wound healing. Clinically, medical staff often manually squeeze the drainage tube, which is not only time-consuming and laborious but also ineffective. Therefore, those skilled in the art are dedicated to developing an auxiliary device that can increase the drainage rate and is easy to carry. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model. The accompanying drawings are schematic diagrams or conceptual diagrams, and the relationships between the thickness and width of each part, as well as the proportional relationships between each part, etc., are not entirely consistent with their actual values.
[0040] Figure 1 A schematic diagram of the structure of a drainage tube pressurization device according to an embodiment of the present invention is shown, including a pressurization component 100, a driving component 200 and a mounting bracket 300. The pressurization component 100 and the driving component 200 are connected to form the main body of the drainage tube pressurization device of this embodiment.
[0041] like Figure 2 and Figure 3 As shown, the pressurizing component 100 includes a housing 110 and a rotating assembly 120, which is disposed within the housing 110. The rotating assembly 120 includes a rotating shaft 121, the two ends of which are connected to a set of bearings disposed within the housing 110, thereby rotatably connecting the rotating assembly 120 to the housing 110.
[0042] like Figure 4 As shown, a plurality of pressure blocks 122 are provided on the rotating shaft 121 of the rotating assembly 120. Preferably, 6 to 12 pressure blocks 122 can be provided. In this embodiment, a total of 10 pressure blocks 122 are provided. When the rotating assembly 120 rotates about the rotating shaft 121, the space that it can cover in the circumferential direction is defined as the rotation coverage range of the rotating assembly 120.
[0043] In this embodiment, all pressure blocks 122 have the same shape, generally forming a fan-shaped columnar structure. The pressure blocks 122 are arranged equidistantly along the axial direction of the rotation shaft 121. Simultaneously, two adjacent pressure blocks 122 have a preset rotation angle along the circumference of the rotation shaft 121. (Refer to...) Figure 5 The diagram shows adjacent pressure blocks 122a and 122b. The position of pressure block 122b relative to pressure block 122a is such that it has rotated around axis 121 by an angle β. Similarly, each subsequent pressure block 122 rotates around axis 121 by an angle β relative to its preceding adjacent pressure block 122. In this embodiment, angle β is 36 degrees, and the 10 pressure blocks 122 cover a 360-degree circumferential range around axis 121. This range can also be set to less than 360 degrees, but preferably not less than 180 degrees.
[0044] The housing 110 defines a space for accommodating the rotating assembly 120, and its structure also defines a fixing groove 111 for fixing the drainage tube. The cross-sectional profile of the fixing groove 111 is arc-shaped, and the diameter of the arc is adapted to the outer diameter of the corresponding drainage tube. The size of the arc notch, i.e., the width of the groove opening of the fixing groove 111, is smaller than the diameter of the arc, allowing the drainage tube to be embedded and fixed in the fixing groove 111 through deformation. The space for accommodating the drainage tube defined by the fixing groove 111 overlaps with the rotation coverage range defined by the rotating assembly 120, so that when the drainage tube is placed in the fixing groove 111, the rotating assembly 120 can cause its pressure block 122 to press the drainage tube in the fixing groove 111. (Reference) Figure 2 and Figure 3 When the rotating assembly 120 rotates clockwise around the rotating shaft 121, the pressure blocks 122 arranged in direction A can press the drainage tube in the fixing groove 111 in sequence. Specifically, it is a push-type press in direction A, which can increase the flow rate of the fluid flowing in direction A in the drainage tube.
[0045] To make the process of the pressure block 122 contacting and pressing the drainage tube smoother and more stable, the edge on the fan-shaped column of the pressure block 122 that first contacts the drainage tube is rounded, as shown in the reference. Figure 6 The rounded corner B shown creates a smooth transition surface. In other embodiments, the edge on the sector-shaped column of the pressure block 122 that contacts the drainage tube is also rounded.
[0046] In this embodiment, the position of the groove opening of the fixing groove 111 corresponds to the rotation direction of the rotating assembly 120. Specifically, the rotation direction of the rotating assembly 120 is from the groove opening of the fixing groove 111 towards the groove. Figure 2 When the rotating assembly 120 rotates clockwise around the rotating shaft 121 and presses the drainage tube in the fixing groove 111, the direction of the frictional force on the drainage tube is the same as the rotation direction of the rotating assembly 120. At this time, the frictional force pulls the drainage tube into the groove of the fixing groove 111, so that the drainage tube can still be stably fixed in the fixing groove 111 during the pressing process. In some embodiments, anti-slip material, such as rubber or silicone, is embedded in the inner wall of the fixing groove 111 to further improve the fixing effect.
[0047] Since the 10 pressure blocks 122 in this embodiment cover a 360-degree circumferential range of the rotating shaft 121, when the drainage tube is embedded into the fixing groove 111, one pressure block 122 will be within the space of the fixing groove 111, which may create some resistance to the drainage tube entering the fixing groove 111. At this time, the rotating component 120 can be activated to rotate it through an angle so that the pressure block 122 rotates out of the space of the fixing groove 111. Since the direction of the frictional force on the drainage tube when the pressure block 122 acts on the drainage tube is to pull it into the fixing groove 111, the drainage tube can be easily embedded into the fixing groove 111 by pushing it from the outside.
[0048] To improve the continuity and stability of the rotating assembly 120 pressing and advancing the drainage tube, it is preferable that adjacent pressure blocks 122 are arranged to overlap. Specifically, the following three methods can be adopted.
[0049] Method 1: Adjacent pressure blocks 122 overlap along the axial direction of the rotating shaft 121, as shown in the reference. Figure 7 The overlapping positions of adjacent pressure blocks 122a and 122b along the axial direction of the rotating shaft 121 are indicated by dashed boxes.
[0050] Method 2: Adjacent pressure blocks 122 overlap circumferentially along the rotation axis 121, see reference. Figure 8 The overlapping positions of adjacent pressure blocks 122a and 122b in the circumferential direction along the rotation axis 121 are indicated by dashed boxes.
[0051] Method 3: Adjacent pressure blocks 122 overlap both axially and circumferentially along the rotating shaft 121, thus combining methods 1 and 2. (See reference...) Figure 9 The dashed boxes indicate the two overlapping positions.
[0052] In this embodiment, three fixing slots 111 of different sizes are provided to make the drainage tube pressurization device of this embodiment applicable to drainage tubes of various specifications. In the prior art, an adjustable distance structure is usually used to make the device applicable to drainage tubes of different specifications. For example, a platform for placing the drainage tube is provided, and the platform is adjustable to change the distance between it and the pressing component, thereby making the device applicable to drainage tubes of different specifications. However, the outer diameter of drainage tubes used in daily life varies greatly. For example, the outer diameter of disposable drainage tubes ranges from 6F to 38F (1F≈0.33mm), a difference of about 6 times. This results in a large difference in the contact area between the drainage tube and the platform when drainage tubes of different specifications are placed on the aforementioned adjustable platform. Generally speaking, when pressing the drainage tube, the platform can cover at least 50% of the outer circumference of the drainage tube, so that the drainage tube can be placed in a semi-circular through groove that matches its outer diameter. This helps to ensure the pressing effect and prevent the drainage tube from rolling due to pressing. However, the aforementioned adjustable tabletop, with its single placement position, cannot ensure that drainage tubes of different specifications can all meet the required contact area with the tabletop. Therefore, the drainage tube pressurization device in this embodiment employs multiple fixing slots 111, each providing sufficient coverage area for its corresponding drainage tube, thus ensuring stable and effective pressing. Typically, a single specialized department commonly uses about 2 to 4 types of drainage tubes, and this setup can basically cover the needs of a single department. Those skilled in the art can also increase the number of fixing slots 111 based on this embodiment, such as by increasing the size of the pressurizing component 100, expanding its outer diameter, thereby enabling the installation of more fixing slots 111. Furthermore, the multiple fixing slots 111 can also meet the need to simultaneously apply pressure to multiple drainage tubes.
[0053] The drive component 200 is connected below the pressurizing component and serves as the power source for driving the rotation assembly 120. It includes a motor, and the rotating shaft 121 of the rotation assembly 120 is connected to the motor shaft. Of course, any existing drive structure or device capable of rotating the rotation assembly 120 can be used, and no limitation is made here. In this embodiment, the drive component 200 also includes a power button 210 and a charging port 220. The power button 210 is used to start / stop the motor, and the charging port 220 is used to charge the built-in battery or to supply power via an external power source. In other embodiments, the drive component 200 also includes speed adjustment and a display screen.
[0054] The mounting bracket 300 is suitable for connecting the main unit consisting of the pressurizing component 100 and the driving component 200, such as... Figure 10 and Figure 11As shown, the hanging bracket 300 includes a hook 310, the structure and size of which are suitable for stably hooking onto the bed frame on the side of the hospital bed. A magnetic material layer 320 is also provided on one outer surface of the hanging bracket 300, allowing the bed frame to be attracted by the magnetic material layer 320 while being hooked, thereby improving the stability of the connection with the bed frame. In other embodiments, the hanging bracket 300 and the main unit are made into an inseparable fixed structure.
