Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary tools, and in particular relates to a negative pressure drainage tube auxiliary bracket. Background Art

[0002] In the medical field, effective support of the drainage tube is very important for drainage patients.

[0003] In the prior art, the invention with application number 202411101031.6 provides a disposable negative pressure drainage tube auxiliary bracket, which belongs to the technical field of drainage tube auxiliary brackets, including a universal adjustment seat group, and a plurality of support seats are equidistantly arranged on the side of the universal adjustment seat group in a circular array, and each support seat is vertically movably connected with a support frame group, and a drainage tube clamp is connected to the top surface of the universal adjustment seat group to form an auxiliary bracket for the drainage tube. This auxiliary bracket adopts three-point stable support and is pasted and fixed to the patient's body surface, so that the drainage tube does not need to be pasted and fixed with oblique pressure after insertion, so that the drainage tube can be straighter without bending, preventing the connection of the drainage tube from becoming smaller and affecting the drainage effect, and the design of the universal adjustment seat group and the drainage tube clamp enables the other end of the drainage tube to be supported and clamped after insertion.

[0004] However, the stent involved in the patent document has many inconveniences in actual use: first, its stability is poor. In daily use scenarios, it is easy to fall over due to being touched, which not only affects the normal supporting function of the drainage tube, but may also cause secondary damage to the patient or interfere with the normal drainage. Secondly, the stent has limitations in the connection between the drainage tube and the universal joint. The drainage tube can only pass through the universal joint up and down. If the drainage tube is to be detached from the universal joint, the drainage tube must be unplugged from the patient or the negative pressure drainage device. This operation process is more troublesome and requires stopping the drainage work, which brings great inconvenience to the patient's treatment. Finally, the patient's convenience of movement is not considered enough. When the patient needs to move, such as going to the toilet, the stent is not convenient to follow the patient to walk, and cannot meet the patient's needs in different scenarios well, which greatly restricts the patient's daily activities.

Detailed implementation manners

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and the above drawings of this application are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and the above drawings of this application are used to distinguish different objects and not to describe a specific order.

[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] An embodiment of the present invention provides a negative pressure drainage tube auxiliary bracket, as Figures 1 - 15 shown, the negative pressure drainage tube auxiliary bracket includes: a base 1 and two symmetrically arranged columns 2 fixed on the base 1, and a lifting assembly 5 is arranged between the two columns 2 for adjusting the height positions of the limiting assembly 3 and the fixing assembly 6; wherein, the limiting assembly 3 is used for limiting the drainage tube, the fixing assembly 6 is used for fixing the bracket on the bed frame of the hospital bed, and the limiting assembly 3 and the fixing assembly 6 are assembled on the lifting assembly 5.

[0040] In this embodiment, the negative pressure drainage tube auxiliary bracket of the present invention includes a base 1 and two symmetrically arranged columns 2 fixed on the base 1, and the lifting assembly 5 arranged between the two columns 2 can adjust the height positions of the limiting assembly 3 and the fixing assembly 6. Wherein the limiting assembly 3 is used for limiting the drainage tube, the fixing assembly 6 is used for fixing the bracket on the bed frame of the hospital bed, and the limiting assembly 3 and the fixing assembly 6 are assembled on the lifting assembly 5.

[0041] During use, first fix the bracket on the bed frame of the hospital bed through the fixing assembly 6, which ensures the stable placement of the entire bracket on the hospital bed, increases the overall stability, and is not easily touched and toppled, so as to continuously and stably support the drainage tube and ensure the smooth progress of the drainage process. Then, use the lifting assembly 5 to adjust the height of the limiting assembly 3, and the height can be flexibly adjusted according to actual needs.

[0042] In a further preferred embodiment of the present invention, the lifting assembly 5 includes: two horizontally arranged crossbars 51 both fixedly installed between the two columns 2, and a vertically arranged support rod 52 fixedly installed between the two crossbars 51; a screw rod 53 rotatably installed on the two crossbars 51 through bearings and arranged vertically, with a turning handle 54 fixedly installed at the top of the screw rod 53; and a lifting seat 55 threadedly sleeved on the screw rod 53 and slidably sleeved on the support rod 52.

[0043] In this embodiment, the lifting assembly 5 includes two horizontal crossbars 51 both fixed between the two columns 2, a vertical support rod 52 fixed between the two crossbars 51, the screw rod 53 rotatably installed on the two crossbars 51 through bearings and arranged vertically, with a turning handle 54 fixed at its top, and a lifting seat 55 threadedly sleeved on the screw rod 53 and slidably sleeved on the support rod 52.

[0044] During use, when it is necessary to adjust the height positions of the limiting assembly 3 and the fixing assembly 6, the turning handle 54 can be rotated. The turning handle 54 drives the screw rod 53 to rotate. Since the lifting seat 55 is threadedly sleeved on the screw rod 53 and slidably sleeved on the support rod 52, during the rotation of the screw rod 53, the lifting seat 55 will move up and down along the screw rod 53, thereby driving the limiting assembly 3 and the fixing assembly 6 assembled on the lifting seat 55 to adjust the height. The beneficial effect of this structure is that the crossbars 51 and the support rod 52 provide a stable frame structure foundation for the entire lifting assembly 5, ensuring the stability of the lifting process. The threaded cooperation between the screw rod 53 and the lifting seat 55 and the sliding cooperation between the lifting seat 55 and the support rod 52 make the height adjustment operation accurate and stable, and can accurately adjust the heights of the limiting assembly 3 and the fixing assembly 6 according to actual needs to better adapt to different usage scenarios, such as the needs for supporting and fixing the drainage tube in the case of patients of different heights or different hospital bed heights.

[0045] In a further preferred embodiment of the present invention, the fixing assembly includes: a connecting block 61 fixed on one side of the lifting seat 55, and a clamping seat 62 fixedly installed on one side of the connecting block 61; a lead screw 63 threadedly installed in a threaded hole opened at the bottom of the clamping seat 62, with a pressing block 64 rotatably sleeved at the top of the lead screw 63 through a bearing; a support base 65 fixed at the bottom of the clamping seat 62, and a motor 66 fixedly installed on the support base 65; a square shaft 67 fixedly installed at the top of the output shaft of the motor 66, the square shaft 67 extending into a square groove opened at the bottom end of the lead screw 63, and the square shaft 67 being adapted to the square groove and vertically slidably connected to the inner wall of the square groove.

[0046] In this embodiment, the fixing component has a connecting block 61 fixed to one side of the lifting seat 55. On one side of the connecting block 61, a clamping seat 62 is fixedly installed. At the bottom of the clamping seat 62, a lead screw 63 is installed by threading, and at its top, a pressing block 64 is rotatably sleeved through a bearing and pressed tightly. At the bottom of the clamping seat 62, a supporting base 65 is fixedly supported. On the supporting base 65, a motor 66 is fixed. At the top of the output shaft of the motor 66, a square shaft 67 is fixed. The square shaft 67 extends into the square groove at the bottom end of the lead screw 63 and is adapted to be vertically slidably connected to the inner wall of the groove.

[0047] During use, start the motor 66. The output shaft of the motor 66 drives the square shaft 67 to rotate. Due to the adaptation relationship between the square shaft 67 and the square groove at the bottom end of the lead screw 63, the square shaft 67 drives the lead screw 63 to rotate. When the lead screw 63 rotates in the threaded hole at the bottom of the clamping seat 62, the pressing block 64 moves up and down relative to the clamping seat 62. When the pressing block 64 moves upward, the clamping seat 62 and the pressing block 64 can be tightly pressed against the upper and lower surfaces of the hospital bed frame, thereby fixing the bracket on the hospital bed frame. The beneficial effect of this structure is that the motor 66 provides power to achieve automated operation, making the fixing process more convenient and efficient. The cooperative design of the connecting block 61, the clamping seat 62, the lead screw 63, and the pressing block 64 can ensure a firm fixing effect, prevent the bracket from shaking or toppling, guarantee the stability of the support for the drainage tube, and thus ensure the smooth progress of the drainage process.

[0048] In a further preferred embodiment of the present invention, rubber pads 68 are fixedly installed on the top of the pressing block 64 and the inner wall of the top of the clamping seat 62, and the two rubber pads 68 are used to tightly press the upper and lower surfaces of the hospital bed frame.

[0049] In this embodiment, rubber pads 68 are fixed on the top of the pressing block 64 and the inner wall of the top of the clamping seat 62, and are used to tightly press the upper and lower surfaces of the hospital bed frame.

[0050] During use, when the pressing block 64 moves downward driven by the lead screw 63, the rubber pad 68 on the top of the pressing block 64 contacts the bottom surface of the hospital bed frame, and the rubber pad 68 on the inner wall of the top of the clamping seat 62 contacts the upper surface of the hospital bed frame. The beneficial effect is that the rubber pad 68 has a certain elasticity and friction. On the one hand, it can increase the friction between the pressing block 64 and the bottom surface of the hospital bed frame, and between the clamping seat 62 and the upper surface of the hospital bed frame, so that the bracket is more firmly fixed on the hospital bed frame, ensuring the stability of the entire negative pressure drainage tube auxiliary bracket and guaranteeing the stable support of the drainage tube. On the other hand, the rubber pad 68 is relatively soft in texture, which can avoid scratching or damaging the hospital bed frame, extend the service life of the hospital bed frame, and at the same time can adapt to the possible small irregular shapes on the surface of the bed frame, making the fixing effect better.

[0051] In a further preferred embodiment of the present invention, the limiting component includes a universal joint first half volute 31 and a universal joint second half volute 32 which are hinged to each other. The universal joint first half volute 31 is fixed on one side of the lifting seat 55. A universal ball 33 is arranged in the universal joint first half volute 31 and the universal joint second half volute 32. A vertical limiting hole is formed in the universal ball 33, and the drainage tube passes through the limiting hole. An operating rod 34 is hinged to one side of the universal joint second half volute 32. A first iron block 35 is fixedly installed on one side of the operating rod 34. The first iron block 35 extends into a first installation groove formed on one side of the universal joint first half volute 31 and contacts a first magnet 36 fixed in the first installation groove, so that the universal joint first half volute 31 and the universal joint second half volute 32 limit the universal ball 33 within the universal joint first half volute 31 and the universal joint second half volute 32.

[0052] In this embodiment, the limiting component has a universal joint first half volute 31 (fixed on one side of the lifting seat 55) and a universal joint second half volute 32 which are hinged to each other. A universal ball 33 with a limiting hole (through which the drainage tube passes) is arranged inside them. An operating rod 34 is hinged to one side of the universal joint second half volute 32. A first iron block 35 on one side of the operating rod 34 extends into a first installation groove on one side of the universal joint first half volute 31 and contacts a fixed first magnet 36 to limit the universal ball 33 within the universal joint first half volute 31 and the universal joint second half volute 32.

[0053] During use, the drainage tube passes through the limiting hole of the universal ball 33. Through the adsorption contact between the first iron block 35 of the operating rod 34 and the first magnet 36, the universal joint first half volute 31 and the universal joint second half volute 32 limit the universal ball 33, thereby restricting the drainage tube. The beneficial effect is that the structural design of the universal joint first half volute 31, the universal joint second half volute 32 and the universal ball 33 enables the drainage tube to flexibly adjust its direction within a certain range, facilitating adaptation to different drainage requirements and changes in the patient's body position. The cooperation of the operating rod 34, the first iron block 35 and the first magnet 36 can conveniently achieve the limitation of the universal ball 33, ensuring that the drainage tube can be stably fixed by the limiting component after the position is adjusted, and guaranteeing the smooth progress of the drainage process.

[0054] In a further preferred embodiment of the present invention, the universal ball 33 is composed of two identical hemispheres. Two symmetric splicing components are arranged on the two hemispheres. The splicing component includes a second iron block 37 and a second magnet 38. The second iron block 37 is installed in a second installation groove on one of the hemispheres, and the second magnet 38 is installed in a third installation groove on the other hemisphere. The second iron block 37 extends into the third installation groove and contacts the second magnet block 38.

[0055] In this embodiment, the universal ball 33 is composed of two identical hemispheres and has a symmetrical splicing assembly including a second iron block 37 and a second magnet 38. The second iron block 37 is in the second installation groove of one hemisphere, and the second magnet 38 is in the third installation groove of the other hemisphere, and the second iron block 37 extends into the third installation groove to contact the second magnet 38.

[0056] During use, this splicing assembly facilitates the assembly and disassembly of the universal ball 33. When special operations need to be performed on the drainage tube, such as inspection, the universal ball 33 can be easily separated into two hemispheres. After the operation is completed, it can be quickly re-spliced into a complete universal ball 33 through the adsorption of the second iron block 37 and the second magnet 38. Its beneficial effect is that it improves the operation convenience, and the universal ball 33 can be operated without complex tools or procedures, reducing the interference during the operation of the drainage tube, ensuring the effectiveness and stability of the drainage tube during the whole use process, and also facilitating the cleaning or maintenance inside the universal ball 33.

[0057] In a further preferred embodiment of the present invention, a clamping assembly is installed at the top of the universal ball 33 for clamping and fixing the drainage tube. The clamping assembly includes: two half pipe shells 41 respectively fixedly installed at the tops of the two hemispheres, and the two half pipe shells 41 are assembled into a cylindrical pipe shape; two fixing frames 42 respectively fixedly installed on the outer walls of the two half pipe shells 41, and two pull rods 43 are slidably installed on the two fixing frames 42; two clamping blocks 44 respectively fixedly installed at the ends of the two pull rods 43 close to each other, and the surfaces of the two clamping blocks 44 close to each other are both arc-shaped and are both installed with cotton-padded rubber blocks 45; two third springs 46 respectively fixedly sleeved on the two pull rods 43, which are used to make the two cotton-padded rubber blocks 45 approach each other under the action of elastic force to clamp the drainage tube.

[0058] In this embodiment, at the top of the universal ball 33, there is a clamping assembly composed of two half pipe shells 41 (assembled into a cylindrical pipe shape and respectively fixed at the tops of the two hemispheres), two fixing frames 42 (respectively fixed on the outer walls of the two half pipe shells 41), two pull rods 43 (slidably installed on the fixing frames 42), two clamping blocks 44 (fixed at the ends of the pull rods 43 close to each other, with arc-shaped close surfaces and installed with cotton-padded rubber blocks 45), and two third springs 46 (sleeved on the pull rods 43 to make the cotton-padded rubber blocks 45 approach each other to clamp the drainage tube).

[0059] During use, when additional fixation of the drainage tube is required, place the drainage tube between the two clamping blocks 44. The elastic force of the third spring 46 will cause the two clamping blocks 44 to approach each other, and the rubber cotton cushion blocks 45 on the clamping blocks 44 will clamp the drainage tube. The beneficial effect is that this clamping assembly provides an additional fixed point for the drainage tube, enhancing the reliability of the drainage tube fixation. The rubber cotton cushion block 45 can both increase the friction with the drainage tube to prevent it from sliding and avoid damaging the drainage tube. The design of the two semi-tube shells 41 assembled into a cylindrical tube shape facilitates cooperation with the universal ball 33. The overall structure is compact and can effectively meet the fixation requirements of the drainage tube in different positions and postures, ensuring the stability of the drainage tube during use.

[0060] In a further preferred embodiment of the present invention, a storage rack 7 is installed on the base 1 for placing a drainage bag or a drainage bottle, and a hook is installed on the storage rack 7 for placing the drainage bag or the drainage bottle in a hanging manner.

[0061] In this embodiment, a storage rack 7 (for placing a drainage bag or a drainage bottle) is installed on the base 1, and there is a hook (for hanging the drainage bag or the drainage bottle) on the storage rack 7.

[0062] During use, the drainage bag or the drainage bottle can be placed on the storage rack 7 and placed in a hanging manner through the hook. The beneficial effect is that the setting of the storage rack 7 and the hook provides a dedicated placement position for the drainage bag or the drainage bottle, making the layout of the entire drainage device more reasonable and orderly. The hanging method facilitates medical staff to observe the liquid volume, color, etc. in the drainage bag or the drainage bottle, and at the same time avoids problems such as dumping and contamination that may be caused by the random placement of the drainage bag or the drainage bottle, ensuring the safety and hygiene of the drainage process.

[0063] In a further preferred embodiment of the present invention, placement boxes 8 are installed at both edges of the top of the base 1 for placing a storage battery and a negative pressure drainage device.

[0064] In this embodiment, there are placement boxes 8 (for placing a storage battery and a negative pressure drainage device) at both edges of the top of the base 1.

[0065] During use, the storage battery and the negative pressure drainage device can be placed in the placement box 8. The beneficial effect is that placing the storage battery and the negative pressure drainage device in the dedicated placement box 8 can protect these important device components from external collisions, dust pollution, etc. Moreover, the placement box 8 installed on the base 1 makes the structure of the entire device more compact, facilitating movement and management, ensuring the stability of the negative pressure drainage device during use, and at the same time, the storage battery placed therein is also convenient for providing stable power supply for the entire drainage-related device.

[0066] To further improve the usage effect of the present device, in addition to the above solution, the present solution also has the following embodiments:

[0067] In another embodiment of the present invention, two support components are assembled on the base 1 for supporting the hands of the patient during pushing.

[0071] In this embodiment, the extension tube 15 is provided with a bolt assembly composed of a fixed block 17 (inside the extension tube 15), first springs 18 (on the fixed block 17), latch blocks 19 (at the ends of the first springs 18 and slidably connected to the limit sliding holes on the inner wall of the extension tube 15), branch steel wire ropes 21 (connecting the latch blocks 19 and penetrating through the guiding sliding holes of the fixed block 17), and a total steel wire rope 22 (connecting the two branch steel wire ropes 21), and the inner walls of both sides of the sleeve 14 are provided with locking holes 20 (into which the latch blocks 19 are snapped).

[0072] During use, when adjusting the relative height of the extension tube 15 and the sleeve 14, the total steel wire rope 22 is pulled, the latch blocks 19 are driven by the branch steel wire ropes 21 to compress the first springs 18, so that the latch blocks 19 are disengaged from the locking holes 20, and at this time, the height can be adjusted. After adjusting to a suitable position, the total steel wire rope 22 is released, and the first springs 18 push the latch blocks 19 to snap into the corresponding locking holes 20, realizing the fixation between the extension tube 15 and the sleeve 14. The beneficial effect is that this bolt assembly has a clever structure and convenient operation, and can simply and effectively realize the fixation after adjustment between the extension tube 15 and the sleeve 14. No additional complex tools are required, which is convenient for patients or medical staff to quickly adjust the height of the grip rod 12 according to needs, ensuring that the support assembly can stably provide hand support for patients at different heights.

[0073] In another embodiment of the present invention, an operating assembly is installed on the grip rod 12 for disengaging the latch blocks 19 from the locking holes 20 when pulling the total steel wire rope 22. The operating assembly includes: two sliding rods 23 fixedly installed inside the grip rod 12, and a long strip plate 24 is slidably sleeved on the two sliding rods 23; two second springs 25 are respectively slidably sleeved on the two sliding rods 23, and the two second springs 25 are located at the top of the long strip plate 24; two pressing blocks 26 fixedly installed at the bottom of the long strip plate 24, the two pressing blocks 26 are slidably connected to the grip rod 12 and extend below the grip rod 12, and the total steel wire rope 22 can be pulled by pressing the two pressing blocks 26 upward.

[0075] During use, when it is necessary to adjust the relative height of the extension tube 15 and the sleeve 14, press the pressing block 26 upward. The pressing block 26 drives the long strip plate 24 to slide upward along the sliding rod 23, compressing the second spring 25. At the same time, the long strip plate 24 pulls the main steel wire rope 22, thereby disengaging the clamping block 19 from the clamping hole 20, and thus the height can be adjusted. After the adjustment is completed, release the pressing block 26, and the elastic force of the second spring 25 causes the long strip plate 24 to reset. The beneficial effect is that the operating assembly makes the operation of adjusting the height of the extension tube 15 and the sleeve 14 more convenient. The patient or medical staff can directly operate at the grip rod 12 without searching for other operating parts, and can control the bolt assembly through a simple pressing action, which is convenient for quickly adjusting the height of the grip rod 12 during the use of the support assembly to meet different needs.
