Description

Technical Field

[0001] This application belongs to the field of medical device technology, and more specifically, relates to an adjustable height drainage bag fixation bracket. Background Technology

[0002] Drainage is a very common post-surgical treatment. Currently, in clinical practice, drainage bags are typically fixed directly to the bed using clips, hooks, or straps. The height of the drainage bag greatly affects the drainage effect. If the drainage bag is not positioned correctly, problems such as excessive or rapid drainage may occur. For example, during ventricular drainage, the drainage bag should not be positioned below the patient's head to maintain stable intracranial pressure. Because the space available to fix the drainage bag on the bed is limited, it is difficult to adjust the height of the drainage bag to a suitable position.

[0003] To address the aforementioned issues, Chinese utility model patent CN221751664U discloses a head drainage bag fixing device, which features a graduated fixing rod. The fixing rod is connected to the hospital bed via a U-shaped fixing seat at the bottom and a locking screw passing through the U-shaped fixing seat. Tightening the clamp with bolts secures the fixing rod, while loosening the bolts adjusts the height of the clamp, allowing the drainage bag to be hung on the clamp, thus achieving height adjustment.

[0004] However, the aforementioned publicly available solution has certain drawbacks. First, the clamp requires bolts to be loosened and tightened to adjust its height, but this method of tightening bolts is inconvenient for medical staff. Second, the fixing rod is only secured by a single fulcrum—the locking screw on the bottom U-shaped fixing seat. As a rod-shaped structure, when its top is subjected to external impacts such as bumps, the long lever arm results in a large torque on the fixing rod, easily causing it to tilt or even detach. In other words, the locking stability achieved through the locking screw on the bottom U-shaped fixing seat is relatively low. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides an adjustable height drainage bag fixing bracket, which facilitates the installation of the drainage bag at a suitable height, and the height adjustment method is simple and the installation is secure.

[0006] To achieve the above objectives, the technical solution of this application provides an adjustable height drainage bag fixing bracket, including a fixed rod with graduations, an upper bracket, a lower bracket, and an adjusting clip; the upper bracket has a vertically extending fixing ring and a horizontally extending upper elastic sleeve, the side wall of which has a horizontal notch, and the upper elastic sleeve can expand the horizontal notch through its own elasticity to wrap around the outside of the upper crossbeam of the bed armrest; the lower bracket has a vertically extending fixing groove and a vertically extending lower elastic sleeve, the side wall of which has a longitudinal notch, and the lower elastic sleeve can expand the longitudinal notch through its own elasticity to wrap around the outside of the longitudinal beam of the bed armrest, and the bottom of the lower elastic sleeve abuts against the top of the side crossbeam of the bed; the top of the fixing groove is open, the fixing ring is located directly above the fixing groove, the fixing rod passes through the fixing ring from the top and is inserted into the fixing groove, the adjusting clip is clamped on the outside of the fixing rod, and the outside of the adjusting clip has a hook for hanging the drainage bag.

[0007] The upper and lower supports utilize the elastic deformation of their own elastic sleeves, allowing for easy connection to the bed railings via a push-pull mechanism. The upper and lower supports provide support at the higher and lower positions of the fixing rod, respectively, resulting in two widely spaced support points. Compared to existing technologies that only use bottom bolts to secure the fixing rod, this reduces the torque experienced when subjected to external impact. More support points and lower torque enhance the fixing rod's impact resistance and increase its installation stability. Furthermore, adjusting the hook height via a pinch-adjustment clip is more convenient than the existing method of tightening bolts on the clamp.

[0008] Optionally, the lateral notch is positioned towards the top, and the longitudinal notch is positioned away from the fixing rod.

[0009] Optionally, the outer wall of the fixing rod is provided with an outer edge that overlaps the top of the fixing ring.

[0010] With the above settings, regardless of whether the fixing rod is impacted in the positive or negative X-axis direction, the positive or negative Y-axis direction, or the negative Z-axis direction, at least one of the upper and lower elastic sleeves will block the movement of the upper or lower bracket, preventing the upper and lower brackets from falling off from the transverse and longitudinal notches at the same time, making the installation of the fixing rod very secure.

[0011] Optionally, several locking protrusions are distributed around the inner wall of the fixing groove to lock the bottom end of the fixing rod, thereby preventing the fixing rod from rotating and reducing the risk of the fixing rod moving due to the force in the positive direction of the Z-axis.

[0012] Optionally, the upper elastic sleeve has a clearance notch in the middle to avoid the longitudinal beam of the bed armrest.

[0013] Optionally, a number of limiting grooves are arranged along the extension direction of the fixed rod, and the inner wall of the adjusting clip has protrusions that match the shape of the limiting grooves. After the adjusting clip is clamped on the fixed rod, the protrusions are placed into any one of the limiting grooves to prevent the adjusting clip from sliding along the fixed rod and to ensure the stability of the height position of the drainage bag.

[0014] Optionally, the upper bracket has an upper limit rod arranged parallel to the fixed rod, and the lower bracket has a lower limit rod arranged parallel to the fixed rod. The fixing ring and the upper elastic sleeve are located on both sides of the upper limit rod, and the fixing groove and the lower elastic sleeve are located on both sides of the lower limit rod. The upper limit rod and the lower limit rod are both arranged opposite to the limiting groove, and the upper limit rod and the lower limit rod both form a gap with the outer side wall of the fixed rod. The adjusting clamp has a front clamp and a rear clamp that are hinged to each other. The protrusion is located on the inner wall of the rear clamp facing the front clamp, and the hook is located on the outer side wall of the front clamp away from the rear clamp. The width of the gap is greater than the thickness of the rear clamp, and the width of the gap is less than the sum of the thickness of the rear clamp and the thickness of the protrusion.

[0015] When the adjusting clamp is squeezed open, the rear clamp can only be moved out of or out of the gap of the corresponding limiting groove by lateral movement. When the protrusion is in the limiting groove, the adjusting clamp cannot move up or down or fall off the fixing rod, regardless of whether the adjusting clamp is open or not. This ensures the stability of the adjusting clamp position. Even if the adjusting clamp is accidentally opened by external force, it will not fall off, thus preventing the drainage bag from falling off.

[0016] Optionally, the front clamp has a semi-circular front clamping part, and the rear clamp has a semi-circular rear clamping part. The protrusion is located on the inner wall of the rear clamping part facing the front clamping part, and the hook is located on the outer wall of the front clamping part away from the rear clamping part. The front clamping part and the rear clamping part are wrapped around and clamped on the outside of the fixing rod, and the rear clamping part can rotate along its own curvature direction to be inserted into the gap.

[0017] The front and rear clamping parts form a ring that completely encloses the fixing rod. Furthermore, if the adjusting clamp is subjected to an external impact, the rear clamping part can only be disengaged from the fixing rod by rotation, and the impact direction is generally linear. This makes it difficult for the adjusting clamp to detach from the fixing rod upon impact, ensuring a secure connection.

[0018] Optionally, the adjusting clamp also includes a rotating shaft and a torsion spring. The front clamp body also has a front pinching part located at the tail end of the front clamping part, and the rear clamp body also has a rear pinching part located at the tail end of the rear clamping part. The tail end of the front clamping part is hinged to the tail end of the rear clamping part through the rotating shaft. The torsion spring is sleeved on the outside of the rotating shaft, and the two abutting ends of the torsion spring abut against the front pinching part and the rear pinching part, respectively.

[0019] Optionally, the bottom of the lower limiting rod is lower than the bottom of the lower elastic sleeve, and the fixing groove is set on the bottom side wall of the lower limiting rod. After the bottom of the lower elastic sleeve abuts against the top of the side beam of the hospital bed, the bottom of the lower limiting rod will be lower than the height of the bed board. The scale at the bottom of the fixing rod can be lower than the bed board, so that the fixing rod has both scales above and below the bed board. The drainage bag can be hung above or below the bed board.

[0020] The advantages of the technical solution in this application compared to the prior art are as follows:

[0021] The upper and lower supports utilize the elastic deformation of the upper and lower elastic sleeves, allowing for easy connection to the bed railings via a push-pull mechanism. The upper and lower supports provide support at the higher and lower positions of the fixing rod, respectively, resulting in two widely spaced support points. Compared to existing technologies that only use bottom bolts to fix the fixing rod, this reduces the torque experienced when the fixing rod is subjected to external impact. More support points and lower torque enhance the fixing rod's impact resistance and increase its installation stability. Furthermore, adjusting the hook height via a pinch-adjustment clip is more convenient than the existing method of tightening bolts on the clamp. Attached Figure Description

[0032] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0033] Example 1:

[0034] This embodiment provides an adjustable-height drainage bag fixing bracket for installation on the armrest 10 on the side of the hospital bed. Based on Figures 1 to 6As shown, the armrest 10 has an upper crossbeam 20 and a longitudinal beam 30. The height-adjustable drainage bag fixing bracket includes a graduated fixing rod 1, an upper bracket 2, a lower bracket 3, and an adjusting clip 4. The upper bracket 2 and the lower bracket 3 are separate structures. The upper bracket 2 has a vertically extending fixing ring 21 and a horizontally extending upper elastic sleeve 22. The side wall of the upper elastic sleeve 22 has a horizontal notch 23. The upper elastic sleeve 22 can expand the horizontal notch 23 through its own elasticity and wrap around the outside of the upper crossbeam 20 of the bed armrest 10. The lower bracket 3 has a vertically extending fixing groove 31 and a vertically extending lower elastic sleeve 32. The side wall of the lower elastic sleeve 32 has a longitudinal notch 33. The lower elastic sleeve 32 can expand the longitudinal notch 33 through its own elasticity and wrap around the outside of the longitudinal beam 30 of the bed armrest 10. After installation, the bottom of the lower elastic sleeve 32 abuts against the top of the side crossbeam 40 of the bed. The upper support 2 and lower support 3 are connected to the bed armrest 10 by the elastic deformation of the upper elastic sleeve 22 and lower elastic sleeve 32, which is more convenient than the existing bolt fastening method. The upper elastic sleeve 22 and lower elastic sleeve 32 can be made of plastic or metal with a certain degree of elasticity to achieve variations in the opening width of the transverse notch 23 and the longitudinal notch 33. Rubber pads or similar materials can also be attached to the inner walls of the upper elastic sleeve 22 and lower elastic sleeve 32 to increase the friction of the connection. The top of the fixing groove 31 is open. After the upper support 2 and lower support 3 are fixed to the armrest 10, the fixing ring 21 is located directly above the fixing groove 31. The fixing rod 1 passes through the fixing ring 21 from the top and is inserted into the fixing groove 31, completing the installation of the fixing rod 1. The adjusting clip 4 is clamped on the outside of the fixing rod 1, and the outside of the adjusting clip 4 has a hook 41 for hanging a drainage bag.

[0035] In use, the position of the adjusting clip 4 is adjusted according to the required height of the drainage bag, following the markings on the fixing rod 1. The upper bracket 2 and the lower bracket 3 support the higher and lower positions of the fixing rod 1 respectively, providing two support points that are relatively far apart. Compared to the prior art where the fixing rod 1 is fixed only by the bottom bolt, the torque experienced by the fixing rod 1 when subjected to external impact is smaller. More support points and smaller torque make the fixing rod 1 more resistant to impact and more secure in installation. Furthermore, adjusting the height of the hook 41 by squeezing the adjusting clip 4 is more convenient than the prior art's method of tightening the bolts on the clamp.

[0036] Preferably, based on Figure 2 and Figure 3 As shown, the horizontal notch 23 faces upwards, and the vertical notch 33 faces away from the fixing rod 1. In actual installation, based on... Figure 3As shown, the upper elastic sleeve 22 is lifted upwards from the bottom of the upper crossbeam 20 along the positive Z-axis, allowing the upper crossbeam 20 to pass through the transverse notch 23, thus completing the installation of the upper support 2. The lower elastic sleeve 32 is pushed from the outside of the bed along the negative Y-axis, allowing the longitudinal beam 30 to pass through the longitudinal notch 33, thus completing the installation of the lower support 3. Since the longitudinal notch 33 is away from the direction of the fixing rod 1, the fixing rod 1 is located at the outer edge of the bed. An avoidance notch 24 is provided in the middle of the upper elastic sleeve 22 to avoid the longitudinal beam 30 of the bed armrest 10. At the same time, the outer side wall of the fixing rod 1 is provided with an outer edge 12 that overlaps the top of the fixing ring 21.

[0037] The above structure reduces the risk of the fixing rod 1 swaying and falling off after impact. Specifically, when the fixing rod 1 is subjected to force in the positive and negative directions of the X-axis, the side walls of the lower elastic sleeve 32 along both sides of the X-axis direction can prevent the lower support 3 from moving in the positive and negative directions of the X-axis, and the edges of the clearance notches 24 on both sides of the elastic sleeve along the X-axis direction can prevent the upper support 2 from moving in the positive and negative directions of the X-axis, thereby preventing the fixing rod 1 from swaying in the X-axis direction. When the fixing rod 1 is subjected to force in the positive and negative directions of the Y-axis, the side walls of the upper support 2 along both sides of the Y-axis direction can prevent the upper support 2 from moving in the Y-axis direction. Even if the lower support 3 accidentally falls off, the fixing rod 1 will not fall off the fixing ring 21 because it is connected to the top of the fixing ring 21 by the outer edge 12. When the fixing rod 1 is subjected to a downward force, i.e., a negative force in the Z-axis direction, the lower support 3 and the fixing rod 1 will not move downward because the bottom end of the lower elastic sleeve 32 abuts against the side beam 40 of the bed. In this way, no matter whether the fixing rod 1 is impacted by the positive or negative X-axis, positive or negative Y-axis, or negative Z-axis, the side wall of at least one of the upper elastic sleeve 22 and the lower elastic sleeve 32 will block the movement of the upper bracket 2 or the lower bracket 3, preventing the upper bracket 2 and the lower bracket 3 from falling off from the transverse notch 23 and the longitudinal notch 33 at the same time, making the installation of the fixing rod 1 very secure.

[0038] Furthermore, based on Figure 3 and Figure 6 As shown, several locking protrusions 34 are distributed around the inner sidewall of the fixing groove 31 to lock the bottom end of the fixing rod 1, preventing the fixing rod 1 from rotating and reducing the risk of the fixing rod 1 moving due to the force in the positive direction of the Z-axis.

[0039] Furthermore, based on Figure 4 , Figure 7 and Figure 8As shown, several limiting grooves 11 are arranged along the extension direction of the fixing rod 1. The limiting grooves 11 can be arranged at equal intervals of 3 cm or 5 cm, or at unequal intervals according to the commonly used adjustment distance. Each limiting groove 11 can serve as a height adjustment position. The inner wall of the adjusting clip 4 has protrusions 42 that match the shape of the limiting grooves 11. After the adjusting clip 4 is clamped onto the fixing rod 1, the protrusions 42 are placed into any one of the limiting grooves 11. In this way, when the adjusting clip 4 clamps the fixing rod 1, the adjusting clip 4 will not move up or down due to the limiting effect of the protrusions 42 and the limiting grooves 11, ensuring the stability of the height position of the drainage bag and preventing it from falling off due to loosening of the adjusting clip 4.

[0040] Preferably, based on Figures 2 to 8 As shown, the upper bracket 2 has an upper limit rod 25 arranged parallel to the fixed rod 1, and the lower bracket 3 has a lower limit rod 35 arranged parallel to the fixed rod 1. The fixing ring 21 and the upper elastic sleeve 22 are located on both sides of the upper limit rod 25, and the fixing groove 31 and the lower elastic sleeve 32 are located on both sides of the lower limit rod 35. Both the upper limit rod 25 and the lower limit rod 35 are opposite to the limiting groove 11, and both the upper limit rod 25 and the lower limit rod 35 form a gap 5 with the outer wall of the fixed rod 1. Correspondingly, the adjusting clamp 4 has a front clamp body 43 and a rear clamp body 44 hinged to each other. A protrusion 42 is located on the inner wall of the rear clamp body 44 facing the front clamp body 43, and a hook 41 is located on the outer wall of the front clamp body 43 away from the rear clamp body 44. The width of the gap 5 is greater than the thickness of the rear clamp body 44, and the width of the gap 5 is less than the sum of the thickness of the rear clamp body 44 and the thickness of the protrusion 42. With the above configuration, the rear clamp 44 can pass through the gap from the side, while the part of the rear clamp 44 with the protrusion 42 can only enter the gap at the corresponding limiting groove 11. When the protrusion 42 is located in the limiting groove 11, the adjusting clamp 4 cannot move up or down or fall off the fixing rod 1, regardless of whether the adjusting clamp 4 is open or not. This ensures the stability of the position of the adjusting clamp 4, and even if the adjusting clamp 4 is accidentally opened by external force, the adjusting clamp 4 will not fall off.

[0041] More preferably, the front clamp 43 has a semi-circular arc-shaped front clamping portion 45, and the rear clamp 44 has a semi-circular arc-shaped rear clamping portion 46. A protrusion 42 is located on the inner wall of the rear clamping portion 46 facing the front clamping portion 45, and a hook 41 is located on the outer wall of the front clamping portion 45 away from the rear clamping portion 46. The front clamping portion 45 and the rear clamping portion 46 are wrapped around and clamped to the outside of the fixing rod 1. Based on Figure 8As shown, the rear clamping part 46 can rotate along its own arc direction to fit into the gap 5. When the adjusting clip 4 clamps the fixing rod 1, the front clamping part 45 and the rear clamping part 46 form a ring that matches the fixing rod 1, completely enclosing the fixing rod 1. This configuration allows the rear clamping part 46 to disengage from the fixing rod 1 only by rotating laterally, while the external impact direction is generally straight. This makes it difficult for the adjusting clip 4 to fall off the fixing rod 1 when impacted, ensuring the firmness of the connection. At the same time, this configuration does not increase the difficulty of operation; simply squeezing the adjusting clip 4 and then rotating it along the fixing rod 1 is sufficient to clamp and disengage the adjusting clip 4 from the fixing rod 1.

[0042] In this embodiment, based on Figure 4 As shown, the adjusting clip 4 also includes a rotating shaft 47 and a torsion spring 48. The front clip body 43 also has a front pinching part 49 located at the tail end of the front clamping part 45, and the rear clip body 44 also has a rear pinching part 410 located at the tail end of the rear clamping part 46. The tail end of the front clamping part 45 is hinged to the tail end of the rear clamping part 46 via the rotating shaft 47. The torsion spring 48 is sleeved on the outside of the rotating shaft 47, and the two abutting ends of the torsion spring 48 abut against the front pinching part 49 and the rear pinching part 410, respectively. The adjusting clip 4 can be opened by engaging the front pinching part and the rear pinching part 410 with two fingers. After releasing the hand, the adjusting clip 4 automatically closes under the action of the torsion spring 48.

[0043] Furthermore, based on Figures 1 to 3 As shown, the bottom end of the lower limit rod 35 is lower than the bottom end of the lower elastic sleeve 32, and the fixing groove 31 is set on the bottom side wall of the lower limit rod 35. After the bottom of the lower elastic sleeve 32 abuts against the top of the side beam 40 of the hospital bed, the bottom end of the lower limit rod 35 will be lower than the height of the bed board. The scale at the bottom of the fixing rod 1 can be lower than the bed board, so that the fixing rod 1 has both a scale higher than the bed board and a scale lower than the bed board. The drainage bag can be hung at a position higher than the bed board or a position lower than the bed board, with a wider adjustment range.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
