Description

Technical Field

[0001] This invention belongs to the technical field of medical devices, specifically relating to a bedside bathing device for premature infants. Background Technology

[0002] The bedside bathing device for premature infants is a mobile bathing device designed for hospital delivery rooms. It adopts a structure that integrates a temperature-controlled water supply system and an oxygen supply device into the vehicle body. It is equipped with four corner wheels at the bottom to enable mobility. The built-in temperature-controlled water heater provides a stable water temperature through a pipeline system, and it can also be equipped with a weighing system to further manage the health of premature infants.

[0003] In practical use, existing bedside bathing devices for premature infants have built-in water tanks, which require connecting the pipes on the water tanks to the pipes of the spraying device inside the washing chamber. The following problems exist during the connection process: 1. When connecting two pipes, threaded connection is now commonly used. However, this method inevitably leads to thread stripping during rotation, and after repeated rotations, the threads wear down, making leakage more likely. 2. When the two pipes are disassembled, the existing device does not have a water collection structure on the outside of the pipes. As a result, after the pipes are disassembled, the water left in the pipes will drip directly into the carrier box, which may cause the carrier box to rust or soak the circuit inside the carrier box. 3. Existing bedside bathing devices for premature infants lack leak detection at the pipe connection point after the two pipes are connected. When water drips at the pipe connection point (mainly referring to leaks that do not affect water pressure, which are generally difficult to detect because they do not affect showering), it is difficult to detect, resulting in water accumulation in the container.

[0004] In summary, a new type of bedside bathing device for premature infants is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a bedside bathing device for premature infants, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A bedside bathing device for premature infants includes a carrier box with casters, a cleaning chamber located at the top of the carrier box, an operating port located on the cleaning chamber, a water storage tank located inside the carrier box, a first pipe and a second pipe respectively located on the cleaning chamber and the water storage tank, and a protective cover located on the outer wall of the first pipe; a sealing mechanism located at the connection between the first pipe and the second pipe for sealing the two; a locking mechanism located on the first pipe to prevent the first pipe and the second pipe from loosening; a disassembly mechanism located on the protective cover for releasing the limiting position between the two second pipes; a leakage observation mechanism located on the protective cover for directly observing whether there is leakage; and a transmission mechanism located inside the protective cover, which cooperates with the locking mechanism to provide power for opening the leakage observation mechanism.

A guide post that cooperates with the first horizontal groove, the second horizontal groove, the arc-shaped groove, and the limiting groove is fixedly connected to the T-shaped block. The depth of the inner groove is greater than the sum of the lengths of the second horizontal groove and the arc-shaped groove.

[0009] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the limiting groove is provided with a sealing member that closes the first transverse groove when the guide column moves into the limiting groove; The closure includes an expanding groove communicating with an arc-shaped groove. A connecting groove communicating with a limiting groove is provided on the expanding groove. The depth of the connecting groove is less than the depth of the expanding groove. An L-shaped block is slidably connected in the connecting groove. The L-shaped block is elastically connected to the inner wall of the expanding groove by a second spring. The L-shaped block has a tangent edge that cooperates with a guide post and an arc edge that cooperates with the arc-shaped groove.

[0010] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the disassembly mechanism includes an arc-shaped opening on the protective cover that communicates with the T-shaped groove, a fixing block that is slidably connected to the arc-shaped opening and fixed to the T-shaped block, and a dial ring with an L-shaped cross section that is rotatably connected to the protective cover, and the fixing block is fixedly connected to the inner wall of the dial ring.

[0011] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the leakage observation mechanism includes a placement groove disposed on the inner wall of the right end of the protective cover, an extension groove connected to the placement groove, water-swellable cotton disposed in the placement groove, and a red coating disposed on the right side wall of the water-swellable cotton.

[0012] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the right side wall of the protective cover is made of acrylic sheet, the carrier box is provided with an observation window, and the connection between the placement groove and the extension groove is arc-shaped.

[0013] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the transmission mechanism includes an arc-shaped support groove disposed within a protective cover, a ring being rotatably connected within the support groove, an inlet on the ring cooperating with the placement groove, a receiving groove communicating with a T-shaped groove on the support groove, a first lever and a second lever respectively on the T-shaped block and the ring, the second lever being elastically connected to the inner wall of the receiving groove via an arc-shaped spring.

[0014] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the second lever is provided with a one-way component to prevent the ring from automatically resetting. The one-way component includes a movable plate fixedly connected to the second lever block. The movable plate is provided with a sliding groove. A transmission block is slidably connected in the guide groove. The transmission block is elastically connected to the inner wall of the guide groove through a third spring. A lever is fixedly connected to the transmission block. The inner wall of the receiving groove is provided with a first guide groove, a second guide groove, a third guide groove, a fourth guide groove, and a fifth guide groove connected end to end. A concave point is provided at the connection between the third guide groove and the fourth guide groove. The vertex of the concave point is located at one end of the third guide groove.

[0015] As a preferred embodiment of the bedside bathing device for premature infants of the present invention, the ring is provided with a water guiding component for guiding water; The water guide includes an L-shaped water-permeable hole on the ring, and a water guide pipe is provided in the support groove that is directly opposite the water-permeable hole. The water guide pipe passes through the protective cover and extends to the outside of the bearing box.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a protective cover, when water leaks at the connection between the first and second pipes, the cover can collect the water, preventing water from dripping directly onto the carrier box and avoiding rusting of the carrier box due to dripping water. It can also protect the lower circuit at the connection between the first and second pipes without having to deliberately avoid the connection between the first and second pipes, which facilitates circuit wiring.

[0017] 2. By setting up a sealing mechanism, a locking mechanism, and a disassembly mechanism, when fixing the first pipe and the second pipe, simply insert the first pipe and the second pipe together, and the first pipe and the second pipe will be automatically fixed by transmission. When disassembling, simply turn the dial ring and then pull the first pipe or the second pipe to disassemble, making the installation or disassembly of the first pipe and the second pipe more convenient.

[0018] 3. By setting up a leak observation mechanism and a transmission mechanism, when a leak occurs, the water-absorbing expansion cotton absorbs water and squeezes the red coating into the extension groove so that it can be seen and understood whether there is a leak, thus achieving a warning effect. In addition, after the first and second pipes are disassembled, the placement groove can be automatically sealed to prevent water in the pipes from soaking into the water-absorbing expansion cotton and causing the water-absorbing expansion cotton to fail.

[0019] 4. By setting up water guide components, when the water inlet on the ring is misaligned with the placement groove, the L-shaped water permeable hole can be aligned with the water guide pipe, thereby draining the water inside the protective cover. This prevents water from flowing out from the left end of the protective cover after the first and second pipes are disassembled, and further prevents water from dripping into the carrier box.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0023] Reference Figure 1 - Figure 8This is the first embodiment of the present invention, which provides a bedside bathing device for premature infants. It enables quick disassembly and installation of the first pipe 15 and the second pipe 16, and prevents water leakage into the carrier box 11 during disassembly. The device includes a carrier box 11 with casters, a cleaning chamber 12 located at the upper end of the carrier box 11, an operating port 13 on the cleaning chamber 12, a water storage tank 14 located in the carrier box 11, the first pipe 15 and the second pipe 16 respectively located on the cleaning chamber 12 and the water storage tank 14, and a device located outside the first pipe 15. The wall includes a protective cover 17; a sealing mechanism located at the connection between the first pipe 15 and the second pipe 16 for sealing the two; a locking mechanism located on the first pipe 15 to prevent the first pipe 15 and the second pipe 16 from loosening; a disassembly mechanism located on the protective cover 17 to release the limiting position between the two pipes 16; a leakage observation mechanism located on the protective cover 17 for directly observing whether there is a leakage; and a transmission mechanism located inside the protective cover 17, which cooperates with the locking mechanism to provide power for opening the leakage observation mechanism.

[0024] The purpose of the cleaning chamber 12 is to reduce hypothermia in premature infants during bathing. It is similar in shape to an infant incubator, with a closed top and two access ports 13 on the side. An oxygen inlet is provided at the end, allowing oxygen to be continuously supplied during bathing. This is existing technology and will not be described in detail here. Casters are provided at the lower end of the carrying box 11 to facilitate overall movement. The carrying box 11 has a water tank 14 inside, which can supply water and eliminate the limitations of water pipes. This is existing technology and will not be described in detail here.

[0025] Furthermore, the sealing mechanism includes a first sealing ring 21 fixedly connected to the first pipe 15 and the second pipe 16, the first sealing ring 21 having an inner groove 22, and a second sealing ring 23 fixedly connected to the first pipe 15 that mates with the inner groove 22; the inner wall of the protective cover 17 has an inclined surface 24 for facilitating water conduction; the engaging mechanism includes an mounting ring 31 fixedly connected to the second pipe 16, the mounting ring 31 having multiple first transverse grooves 32, and an arc-shaped groove 33 communicating with the first transverse grooves 32. The upper part of the 3 is provided with a second transverse groove 34, and the upper part of the second transverse groove 34 is provided with a limiting groove 35. The protective cover 17 is provided with multiple arc-shaped T-shaped grooves 36. T-shaped blocks 37 are slidably connected in the T-shaped grooves 36. The T-shaped blocks 37 are elastically connected to the inner wall of the T-shaped grooves 36 by a first spring. The T-shaped blocks 37 are fixedly connected with guide posts 38 that cooperate with the first transverse groove 32, the second transverse groove 34, the arc-shaped groove 33, and the limiting groove 35. The depth of the inner groove 22 is greater than the sum of the lengths of the second transverse groove 34 and the arc-shaped groove 33.

[0026] Here, the second sealing ring 23 is inserted into the inner groove 22 of the first sealing ring 21. When the second pipe 16 is moved at the beginning of disassembly, there will be no liquid leakage. The slope 24 is set so that after the first pipe 15 and the second pipe 16 are separated, the water dripping from the first pipe 15 and the second pipe 16 will accumulate at the right end of the protective cover 17 and will not leak out from the protective cover 17. Here, the connection between the first pipe 15 and the second pipe 16 is completely on the upper side of the slope 24, ensuring that the water will flow along the slope 24 to the right end of the protective cover 17.

[0027] Preferably, the limiting groove 35 is provided with a closing member 39 that closes the first transverse groove 32 when the guide post 38 moves into the limiting groove 35; the closing member 39 includes an expanding groove 391 communicating with the arc-shaped groove 33, and a connecting groove 392 communicating with the limiting groove 35 is provided on the expanding groove 391. The depth of the connecting groove 392 is less than the depth of the expanding groove 391. An L-shaped block 393 is slidably connected in the connecting groove 392. The L-shaped block 393 is connected to the expanding groove by a second spring 394. The inner wall of 391 is elastically connected. The L-shaped block 393 is provided with a cut edge 395 that cooperates with the guide post 38. The L-shaped block 393 is provided with an arc edge that cooperates with the arc groove 33. The disassembly mechanism includes an arc-shaped opening 41 on the protective cover 17 that communicates with the T-shaped groove 36. A fixing block 42 that is fixed to the T-shaped block 37 is slidably connected in the arc-shaped opening 41. A dial ring 43 with an L-shaped cross section is rotatably connected on the protective cover 17. The fixing block 42 is fixedly connected to the inner wall of the dial ring 43.

[0028] It should be noted that the closure 39 here can close the first transverse groove 32 after the guide post 38 enters the limiting groove 35 and is limited, preventing water from entering the T-shaped groove 36 from the first transverse groove 32, the arc groove 33, etc., and leaking from the arc opening 41. The tangent 395 is set to prevent the guide post 38 from getting stuck between the guide post 38 and the L-shaped block 393. When the dial ring 43 rotates, it can drive multiple fixed blocks 42 to move simultaneously, thereby realizing the release of the limit at multiple positions.

[0029] During use and installation, simply align the guide post 38 with the transverse groove. Reference lines can be set on both the protective cover 17 and the mounting ring 31, ensuring that the two reference lines are aligned to guarantee the correct connection between the first pipe 15 and the second pipe 16. After the guide post 38 aligns with the transverse groove, push the second pipe 16 to allow the protective cover 17 and the mounting ring 31 to continue moving closer. At this time, the guide post 38 slides within the first transverse groove 32. When the guide post 38 slides to halfway through the first transverse groove 32 (this is a relative motion description; in reality, the second pipe 16 moves closer to the first pipe 15, and the mounting ring 31 moves towards the protective cover 17), the second sealing ring 23 enters the inner groove 22. As the protective cover 17 continues to move, the second sealing ring 23 continues to slide within the inner groove 22. The sealing of the first pipe 15 and the second pipe 16 is achieved when the second sealing ring 23 is within the inner groove 22. When the guide post 38 moves into the arc-shaped groove 33, guided by the arc-shaped groove 33, the guide post 38 will move towards the first spring, thereby causing the T-shaped block 37 to slide in the T-shaped groove 36, compressing the first spring. When the guide post 38 moves into the second transverse groove 34, the first spring is still in a compressed state. When the guide post 38 moves to the connection between the limiting groove 35 and the second transverse groove 34, under the action of the first spring, the T-shaped block 37 resets, causing the guide post 38 to reset. At this time, the inner wall of the guide post 38 abuts against the limiting groove 35, so that in the left and right directions, the protective cover 1... 7 cannot be separated from the mounting ring 31, thus achieving the fixation between the first pipe 15 and the second pipe 16. During disassembly, even if the first pipe 15 and the second pipe 16 are separated, the protective cover 17 will collect the liquid. It is worth noting that when the first pipe 15 and the second pipe 16 are separated, the valve will be closed in advance, so that only a small amount of water enters the protective cover 17. Under the guidance of the inclined surface 24, it enters the right end of the protective cover 17, and there will be no liquid outflow. Here, it is generally assumed that the first pipe 15 is fixed, and the second pipe 16 is mainly moved when moving. The above describes the anti-drip design during disassembly. In case of leakage, an L-shaped block 393 blocks the water and seals the first transverse groove 32, preventing water in the protective cover 17 from flowing into the arc-shaped opening 41 through the first transverse groove 32. The movement process is as follows: when the guide post 38 enters the limiting groove 35, it can also push the L-shaped block 393 towards the first transverse groove 32 and seal the first transverse groove 32, preventing water from moving from the first transverse groove 32 into the T-shaped groove 36 and flowing out from the arc-shaped opening 41. Thus, in case of leakage, the water will be stored in the protective cover 17. The protective cover 17 is made of transparent acrylic sheet, which can be directly observed inside to check for leaks. When it is necessary to disassemble the first pipe 15 and the second pipe 16, simply rotate the dial ring 43 to move the fixing block 42, which in turn moves the T-shaped block 37 within the T-shaped groove 36, causing the guide post 38 to move to the connection between the second transverse groove 34 and the limiting groove 35. At this point, pull the second pipe 16 to separate the protective cover 17 from the mounting ring 31. The guide post 38 can then move along the second transverse groove 34 to the arc groove 33 and finally return to its original position via the first transverse groove 32. It is worth noting that when the guide post 38 leaves the limiting groove 35, the L-shaped block 393 can automatically return to its original position under the action of the second spring 394. After the guide post 38 moves into the arc groove 33, it will not obstruct the guide post 38 from moving into the first transverse groove 32.

[0030] In summary, in this embodiment, after the first pipe 15 and the second pipe 16 are connected, a closed protection is formed on the outside of the first pipe 15 and the second pipe 16 to prevent water from dripping into the carrier box 11 in case of leakage. It can also catch dripping water when the first pipe 15 and the second pipe 16 are disassembled, preventing water from dripping into the carrier box 11 during disassembly. This eliminates the need for special water cleaning afterward and prevents the carrier box 11 from rusting or being damaged by internal circuitry due to water accumulation. Example 2

[0031] Reference Figure 1 - Figure 11 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a leak observation mechanism for the bedside bathing device for premature infants, solving the problem of how to quickly detect leaks. It includes an arc-shaped placement groove 51 on the inner wall of the right end of the protective cover 17, with an extension groove 52 connected to the placement groove 51. Water-swellable cotton is placed inside the placement groove 51, and the right side wall of the water-swellable cotton has a red coating 54. The right side wall of the protective cover 17 is made of acrylic sheet, and the carrier box 11 has an observation window. The connection between the placement groove 51 and the extension groove 52 is arc-shaped; the transmission mechanism includes an annular support groove 61 set in the protective cover 17, a ring 62 is rotatably connected in the support groove 61, the ring 62 is provided with an arc-shaped water inlet 63 that cooperates with the placement groove 51, the support groove 61 is provided with a receiving groove 64 that communicates with the T-shaped groove 36, the T-shaped block 37 and the ring 62 are respectively provided with a first lever 65 and a second lever 66, the second lever 66 is elastically connected to the inner wall of the receiving groove 64 through an arc-shaped spring 67.

[0032] Specifically, the red layer here can be red paint, red paper, or even red marker, etc., as long as it can provide a noticeable reminder. When the water-absorbing cotton has not absorbed water, the red layer is in the placement groove 51 and does not extend to the extension groove 52, so it is not easily seen. The arc-shaped design allows the water-absorbing cotton 53 to expand and enter the extension groove 52 more effectively. The observation window allows the extension groove 52 to be seen directly.

[0033] Furthermore, the second lever 66 is provided with a one-way component 68 to prevent the ring 62 from automatically resetting; the one-way component 68 includes a movable plate 681 fixedly connected to the second lever 66, the movable plate 681 is provided with a sliding groove 682, a transmission block 683 is slidably connected in the guide groove, the transmission block 683 is elastically connected to the inner wall of the guide groove by a third spring, a lever 684 is fixedly connected to the transmission block 683, and the inner wall of the receiving groove 64 is provided with a first guide groove 685, a second guide groove 686, a third guide groove 687, a fourth guide groove 688, and a fifth guide groove 689 connected end to end, the connection between the third guide groove 687 and the fourth guide groove 688 is provided with a concave point, and the vertex directly opposite the concave point is at one end of the third guide groove.

[0034] It should be noted that with the concave point, the lever 684 will not automatically reset when it is in the concave point. The vertex directly opposite the concave point is at one end of the third guide groove. Therefore, when the lever 684 is pushed for the second time, due to the obstruction of the rear side wall edge of the third guide groove, the lever 684 directly enters the fourth guide groove, so that it can move from the fourth guide groove to the fifth guide groove and finally reset.

[0035] In use, when the guide post 38 moves from the first horizontal groove 32 into the arc groove 33, the T-shaped block 37 slides in the T-shaped groove 36, causing the first lever 65 to move, which in turn drives the second lever 66 to move, which in turn drives the moving plate 681 to move, causing the lever 684 to move from the first guide groove into the second guide groove. Here, the fifth guide groove is set in the same way as the first guide groove, and the third and fourth guide grooves are set in the same way. When the lever 684 is pushed, it directly enters the second guide groove from the first guide groove, instead of the fifth guide groove. The lever 684 moves along the second guide groove to the connection between the second guide groove and the third guide groove. Then, when the second lever 66 is reset, it automatically enters the concave point of the third and fourth guide grooves. At this time, the lever 684 cannot be reset, and the square plate cannot be reset. At this time, even if the first lever 65 is reset, the second lever 66 cannot be reset. When the second lever 66 moves, it will drive the ring 62 to rotate, so that the water inlet 63 on the ring 62 is directly opposite the placement groove 51, and water can enter the placement groove 51. When water leaks, under the guidance of the inclined surface 24, the water will come into contact with the water-absorbing expansion cotton 53, causing the water-absorbing expansion cotton 53 to expand. At this time, the water-absorbing expansion cotton 53 will be squeezed into the extension groove 52, so the red coating 54 is squeezed into the extension groove 52. The red area can be directly seen through the observation window, thus indicating the water leak. It is worth noting that when disassembling the first pipe 15 and the second pipe 16, moving the first lever 65 will cause the second lever 66 to be moved again. Through transmission, the lever 684 continues to move. At this time, since the vertex opposite the concave point is at one end of the third guide groove, the lever 684 moves directly into the fourth guide groove, and finally returns to the connection between the first guide groove and the fifth guide groove via the fifth guide groove, so that the square plate is reset. The second lever 66 is reset under the action of the arc spring 67, so that the water inlet 63 on the ring 62 is misaligned with the placement groove 51, preventing water from entering. When the device enters the placement groove 51, since the depth of the inner groove 22 is greater than the sum of the lengths of the second horizontal groove 34 and the arc groove 33, the sealing ring has not completely left the inner groove 22 when the water inlet 63 on the ring 62 is misaligned with the placement groove 51. This ensures that the placement groove 51 is in a closed state after the first pipe 15 and the second pipe 16 are separated, preventing water dripping after disassembly from soaking the water-absorbing and expanding cotton 53. It is worth noting that during the movement of the lever 684, the transmission block 683 slides in the slide groove 682 to prevent the lever 684 from getting stuck during the movement.

[0036] In summary, by setting up a leakage observation mechanism and a transmission mechanism, when a leakage occurs, the water-absorbing expansion cotton 53 absorbs water and squeezes the red coating 54 into the extension groove 52 so that it can be seen and understood whether there is a leakage. In addition, after the first pipe 15 and the second pipe 16 are disassembled, the placement groove 51 can be automatically sealed to prevent water in the pipes from soaking into the water-absorbing expansion cotton 53 and causing the water-absorbing expansion cotton 53 to fail. Example 3

[0037] Reference Figure 1 - Figure 11 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a water guide 69 for a bedside bathing device for premature infants, which solves the problem of water guidance when there is a lot of water during disassembly. It includes an L-shaped water-permeable hole 691 set on a ring 62, and a water guide pipe 692 facing the water-permeable hole in the support groove 61. The water guide pipe 692 passes through the protective cover 17 and extends to the outside of the carrier box 11. Here, a water receiving bottle can be set at the outer end of the carrier box 11. The height of the bottle opening is less than the height of the protective cover 17, so as to collect the water in the water guide pipe 692.

[0038] When in use, when the water inlet 63 on the ring 62 is misaligned with the placement groove 51, that is, when the placement groove 51 is closed, the L-shaped water permeable hole 691 is aligned with the water guide pipe 692. At this time, the L-shaped water guide hole guides two types of water. One is the water that accumulates in the protective cover 17 after the water-absorbing and expanding cotton 53 absorbs water to its maximum limit after the first pipe 15 and the second pipe 16 are connected and leak. The other is the water that remains in the first pipe 15 and the second pipe 16 and flows into the protective cover 17 when the first pipe 15 and the second pipe 16 are disassembled. This is mainly to prevent the water from accumulating too much in the protective cover 17 and flowing out from the left end of the protective cover 17 during disassembly. When guiding water, the water enters the L-shaped water guide hole from the protective cover 17 and then enters the water guide pipe 692.

[0039] In summary, by setting the water guide 69, even when the water inlet 63 on the ring 62 is misaligned with the placement groove 51, the L-shaped water permeable hole 691 can be aligned with the water guide pipe 692, thereby allowing water to be discharged from the protective cover 17 and preventing water from flowing out from the left end of the protective cover 17 after the first pipe 15 and the second pipe 16 are disassembled.
