Description
Technical Field
[0001] This invention belongs to the technical field of drug delivery and nursing devices, specifically relating to an intelligent nebulized drug delivery device adapted for neonatal diaper rash. Background Technology
[0002] In recent years, to ensure even administration of medication for diaper rash in newborns and improve absorption, neonatal diaper rash nebulizers have emerged in hospitals. These devices employ ultra-gentle parameters to avoid irritating delicate skin and utilize medical ultrasonic nebulization technology to precisely control particle size, allowing for better absorption by the newborn's buttocks. During use, the device features a touchscreen for direct control of dosage and atomized particles. Medication is administered simply by moving the spray nozzle. The device also includes a multi-directional curved tube for directional movement of the spray nozzle.
[0003] To avoid cross-infection, the spray covers are disposable and need to be replaced each time. The existing spray cover fixing method is mainly based on interference fit for limiting. After repeated insertion and removal, the pipe on the multi-directional bend is prone to deformation, which affects the limiting between the spray cover and the multi-directional bend. In addition, the existing multi-directional bend is exposed when not in use, which makes it easy for dust to enter. When the dust enters the spray tube, it is easy to be sprayed out along with the atomized medicine onto the newborn's buttocks during the next use, which can easily cause newborn rashes, itching and other problems.

Detailed Implementation
[0021] 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.
[0022] Reference Figure 1 - Figure 8 This invention provides an intelligent nebulized drug delivery device for neonatal diaper rash, which automatically prevents dust from entering the spray tube 15 when it is not in use. The device includes a nursing machine body 10, with a multi-directional bend 11 at its upper end. A connecting tube 12 with one open end is located at the front end of the multi-directional bend 11. A spray tube 13 is located at the outer end of the connecting tube 12, and a spray hood 14 is located at the front end of the spray tube 13. The spray tube 15 is located inside the connecting tube 12. A connecting mechanism is also provided between the spray tube 13 and the connecting tube 12. The upper part is used to fix the connecting tube 12 and the spray pipe 13; the sealing mechanism is set inside the connecting tube 12, which automatically seals the connecting tube 12 when not spraying to prevent dust from entering the connecting tube 12 or the spray pipe 15; the bending mechanism is set on the multi-directional bend pipe 11 and the connecting tube 12, which makes the connecting tube 12 face downward to prevent dust when not spraying; the locking mechanism is set inside the connecting tube 12, which prevents the connecting tube 12 from always facing downward when the connecting tube 12 is in use.
[0023] The nursing machine body 10 is equipped with an operation panel, and the spray pipe 13 and spray cover 14 are combined to form a spray head. The nursing machine has the following automated functions: 1. Intelligent adaptation and layered care Weight-linked adjustment: The infant's weight can be manually entered or obtained by connecting an external scale, and the system automatically matches three care plans: premature infant (<2.5kg), low birth weight infant (2.5-4kg), and full-term infant (≥4kg). The premature infant mode uses ultra-gentle parameters to avoid irritating the delicate skin; the full-term infant mode balances efficiency and safety.
[0024] Graded care for diaper rash: The control panel has preset options for grades I-IV diaper rash. Grades I-II follow the basic procedure of "rinsing-drying-nebulized drug administration"; grades III-IV ulcerated diaper rash automatically switch to the "wet dressing-low-dose nebulization-infrared repair-low-temperature drying" mode to reduce wound irritation.
[0025] 2. Nebulized drug delivery is precise and efficient. Exclusive atomization design: Medical ultrasonic atomization technology precisely controls the particle diameter to 5-10μm, covering wrinkles while avoiding inhalation risks; equipped with an ointment dilution chamber with markings for commonly used diaper rash medications, solving the problem of atomizing viscous ointments.
[0026] 360° Targeted Nozzle: Combined with the multi-directional curved tube 11, the flexible silicone nozzle (the nozzle is composed of the spray tube 13 and the spray cover 14) can rotate 360° and conforms to the curve of the buttocks, increasing the drug utilization rate by more than 50% compared to applying with cotton swabs.
[0027] 3. Infrared repair accelerates healing. Precise temperature-controlled irradiation: 630-660nm low-energy infrared rays promote blood circulation and cell repair, while dual monitoring of distance and temperature ensures a lamp distance of 30-40cm and a skin temperature of 38-40℃, preventing burns.
[0028] Intelligent linkage program: During treatment of grade III-IV diaper rash, infrared irradiation is automatically activated after nebulization (10 minutes / time for grade III, 15 minutes / time for grade IV), and automatic drying is performed after the treatment, forming a closed loop of "medication - healing promotion - protection".
[0029] Clinically compatible structure: The lamp head is foldable and retractable, compatible with incubators and radiant warmers, and the surface is covered with a disposable sterile protective film, meeting hospital infection control requirements.
[0030] 4. One-click linkage, standardized process Automatic operation: Integrates five major functions: rinsing, drying, atomization, infrared, and recording. The entire process can be completed automatically with one-button start, reducing the single case care time from 15 minutes to 5 minutes.
[0031] Data traceability: Automatically records patient information and nursing parameters, supports integration with electronic medical records, generates standardized nursing records, and facilitates tracking and quality control.
[0032] 5. Safety and Infection Control Aseptic configuration: The nozzles and protective films that come into contact with the child are all disposable sterile consumables, and the body is made of medical-grade 304 stainless steel, which is resistant to wiping with chlorine-containing disinfectants.
[0033] Multiple warnings: Automatic shutdown and audible and visual alarms when water pressure is abnormal, temperature is too high, atomization exceeds the standard, or distance is too close, to prevent skin damage.
[0034] Clinical usage process 1. Preparation: Push the equipment next to the child and fix it in place, and adjust the height; select a treatment plan according to the child's weight and diaper rash grade; install the disposable nozzle cover and lamp head protective film; add the rinsing solution and diluted ointment.
[0035] 2. Nursing care: Expose the child's buttocks, align the nozzle with the device and start it with one button. The device will automatically execute the corresponding procedure, and medical staff only need to observe the child's reaction.
[0036] 3. Finishing: After the nursing care is completed, the equipment automatically uploads the data; remove and discard the consumables, wipe and disinfect the machine, and return it to its original position.
[0037] The above are existing technologies and will not be elaborated upon here.
[0038] Furthermore, the connecting mechanism includes multiple inner grooves 21 disposed on the connecting cylinder 12, a push block 22 slidably connected in the inner groove 21, the push block 22 being elastically connected to the inner wall of the inner groove 21 by a first spring 23, the spray pipe 13 being provided with multiple bayonets 24 that cooperate with the push block 22, the upper end of the push block 22 being provided with a first inclined surface 25 that cooperates with the spray pipe 13, a stop ring 26 that cooperates with the spray pipe 13 being fixedly connected to the connecting cylinder 12; the connecting cylinder 12 is provided with a disassembly component 27 for disassembling the spray cover 14; the disassembly component 27 includes an upper open mounting cylinder 271 rotatably connected to the connecting cylinder 12, a lever 272 being fixedly connected to the inner wall of the mounting cylinder 271, a second inclined surface 273 that cooperates with the lever 272 being provided on the side wall of the push block 22, and a third inclined surface 274 that cooperates with the bayonets 24 being provided at the lower end of the push block 22.
[0039] The first inclined surface 25 is designed to prevent jamming between the bayonet 24 and the push block 22 when installing the spray pipe 13. The second inclined surface 273 is designed to prevent jamming between the push block 272 and the push block 22. The third inclined surface 274 is designed to ensure that the spray pipe 13 can be pulled out during disassembly, and to prevent the spray pipe 13 from getting stuck during disassembly.
[0040] Preferably, the closing mechanism includes an L-shaped annular groove 31 disposed within the connecting cylinder 12. Multiple pairs of mounting blocks 32 are fixedly connected within the annular groove 31. A rotating shaft 33 is rotatably connected between each pair of mounting blocks 32. A fixing block 34 is fixedly connected to the rotating shaft 33. A sector plate 35 is fixedly connected to the fixing block 34. The multiple sector plates 35 cooperate to close the connecting cylinder 12. A pushing member 36 is provided within the annular groove 31 to provide power for the rotation of the sector plate 35. The pushing member 36 includes an installation port disposed within the annular groove 31 and communicating with the inner groove 21. A toothed plate 361 is slidably connected within the installation port. The toothed plate 361 has a tangent edge 362 that cooperates with the push block 22. A gear 363 that meshes with the toothed plate 361 is fixedly connected to the rotating shaft 33.
[0041] It should be noted that when the spray pipe 13 is not installed, multiple sector plates 35 are connected to the connecting cylinder 12 for sealing. At this time, the spray pipe 15 is protected inside the connecting cylinder 12, preventing dust from entering the spray pipe 15. The setting of the cut edge 362 avoids the phenomenon of jamming between the toothed plate 361 and the push block 22.
[0042] In use, the spray pipe 13 and the spray hood 14 are a single unit (here, for ease of description, they are disassembled into two parts). They need to be replaced after each use; they are disposable. When the spray pipe 13 is not installed, the sector plate 35 closes the connecting cylinder 12. When installing the spray pipe 13, simply align the bayonet 24 on the spray pipe 13 with the push block 22, and then push the spray pipe 13 towards the connecting cylinder 12. When the bayonet 24 abuts against the first inclined surface 25 of the push block 22, it can push the push block 22 inward. When the groove 21 moves, the first spring 23 is compressed. When the push block 22 is aligned with the bayonet 24, the stop ring 26 on the connecting cylinder 12 abuts against the spray pipe 13 to prevent the spray pipe 13 from continuing to move towards the connecting cylinder 12. Then, under the action of the first spring 23, the push block 22 moves outward. At this time, the non-second inclined surface 273 of the push block 22 abuts against the side wall of the bayonet 24 to prevent the spray pipe 13 from resetting, thereby limiting the connection between the connecting cylinder 12 and the spray pipe 13 and installing the spray pipe 13 and the spray cover 14. When it is necessary to disassemble the spray tube 13, simply rotate the mounting cylinder 271 so that the lever 272 abuts against the second inclined surface 273 on the push block 22. At this time, the push block 22 will move towards the inner groove 21. It is worth noting that the outer wall of the lever 272 abuts against the outer wall of the spray tube 13, so it will not affect the installation of the spray tube 13. The push block 22 moves inward, so that the third inclined surface 274 of the push block 22 abuts against the inner wall of the bayonet 24. At this time, the spray tube 13 can be pulled out directly. It is worth noting that after the push block 22 is fully pushed out, the bayonet 24 abuts against the bottom of the push block 22 (excluding the third inclined surface 274), and the spray tube 13 will not be reset. When the pusher 22 moves toward the inner groove 21 for the first time, it will push the toothed plate 361 toward the inside of the connecting cylinder 12, thereby driving the gear 363 to rotate, causing the rotating shaft 33 to rotate. The rotating fixed block 34 drives the sector plate 35 to deflect, causing the outer end of the connecting cylinder 12 to open, and the spray from the spray pipe 15 can be sprayed into the connecting cylinder 12, and then sprayed to the required place through the spray pipe 13 and the spray hood 14.
[0043] Reference Figure 1 - Figure 9 It provides a one-way component 37 for intelligently adapting to neonatal diaper rash atomizing drug delivery device, and solves the problem of how to prevent the toothed plate 361 from automatically resetting when the push block 22 is reset for the first time. Its connecting cylinder 12 is equipped with a one-way component 37 to prevent the fan-shaped plate 35 from automatically resetting. One-way component 37 includes an L-shaped mounting groove 371 disposed within the connecting cylinder 12. An L-shaped plate 372, fixed to the toothed plate 361, is slidably connected within the mounting groove 371. The mounting groove 371 has a guide opening 373 that mates with the L-shaped plate 372. An arc-shaped plate 374 is fixedly connected to the L-shaped plate 372. The L-shaped plate 372 is elastically connected to the inner wall of the mounting groove 371 via a telescopic spring. The arc-shaped plate 374 has a through opening, within which an arc-shaped block 375 is slidably connected. The arc-shaped block 375 is connected via a second spring 37. 6 is elastically connected to the inner wall of the through-hole. A guide post 377 is fixedly connected to the arc-shaped block 375. The inner wall of the mounting groove 371 is provided with a first guide groove 378, a second guide groove 379, a third guide groove 3710, a fourth guide groove 3711, and a fifth guide groove 3712 that cooperate with the guide post 377 and are connected end to end. The connection between the third guide groove 3710 and the fourth guide groove 3711 forms a concave point that cooperates with the guide post 377. A triangular block 3713 with its vertex facing the third guide groove 3710 is provided at the relative position of the concave point.
[0044] Specifically, a triangular block 3713 with its vertex facing the third guide groove 3710 is provided at the relative position of the concave point, so that when the guide post 377 starts from the convex point, it will directly enter the fourth guide groove 3711 and finally be reset through the fifth guide groove 3712, instead of returning to the third guide groove 3710. Here, a triangular block 3713 can also be provided at the connection between the fifth guide groove 3712 and the first guide groove 378, so that the guide post 377 can directly enter the first guide groove 378 from the connection between the fifth guide groove 3712 and the first guide groove 378, instead of the fifth guide groove 3712.
[0045] During use, when the toothed plate 361 moves, it can also drive the L-shaped plate 372 to slide within the mounting groove 371, thereby driving the arc-shaped plate 374 to move. When the arc-shaped plate 374 moves, the guide post 377 on the arc-shaped plate 374 first moves from the connection between the fifth guide groove 3712 and the first guide groove 378 to the first guide groove 378, and then moves from the second guide groove 379 to the connection between the second guide groove 379 and the third guide groove 3710. During this process, the telescopic spring is compressed. When the push block 22 is inserted into the latch 24, the push block 22 will be misaligned with the toothed plate 361. At this time, under the action of the telescopic spring, the arc-shaped plate 374 will reset a small section, causing the guide post 377 to move to the concave point at the connection between the third guide groove 3710 and the fourth guide groove 3711. Since the concave point blocks the reset of the guide post 377, the toothed plate 361 will not be completely reset, thus preventing the gear 363 from resetting and avoiding the fan-shaped transmission. Plate 35 seals the connecting cylinder 12. When push block 22 is disassembled, push block 22 moves towards the inner groove 21 for the second time. At this time, push block 22 pushes toothed plate 361 for the second time. At this time, the arc plate 374 moves through the transmission. Due to the setting of triangular block 3713, the guide column 377 moves directly from the concave point to the fourth guide groove 3711 and enters the connection between the fourth guide groove 3711 and the fifth guide groove 3712. Finally, when the spray pipe 13 is taken out, push block 22 resets. At this time, guide column 377 resets from the fifth guide groove 3712 to the connection between the first guide groove 378 and the fifth guide groove 3712. Thus, toothed plate 361 resets, gear 363 resets, rotating shaft 33 resets, driving fixed block 34 to reset, and sector plate 35 resets, thereby re-sealing the connecting cylinder 12 and realizing dust prevention of spray pipe 15. It is worth noting that the arc block 375 slides in the through-hole to avoid the guide column 377 from getting stuck.
[0046] Reference Figure 1 - Figure 10A bending mechanism for intelligently adapting to neonatal diaper rash nebulizers is provided, solving the problem of how to further prevent dust from entering the connecting tube 12. This mechanism includes a notch 41 on the multi-directional bend 11, with a mounting shaft 42 rotatably connected within the notch 41. A transition block 43, fixed to the connecting tube 12, is fixedly connected to the mounting shaft 42. The locking mechanism includes an L-shaped extension groove 51 located within the connecting tube 12 and extending into the transition block 43. A transmission plate 52, fixed to the arc-shaped plate 374, is slidably connected within the extension groove 51. The transition block 43 is provided with a connection to the extension groove. The expansion slot 53 is connected to 51. The expansion slot 53 has two sockets. The inner wall of the notch 41 has two slots 54 that mate with the sockets. The transmission plate 52 is fixedly connected to the support plate 55. The socket is slidably connected to the T-shaped plug 56 that mates with the slot 54. The plug 56 is fixedly connected to the L-shaped rod 57. The support plate 55 has a slanted groove 58 that mates with the L-shaped rod 57. When the adapter block 43 abuts against the inner wall of the notch 41, the socket, slot 54 and T-shaped block are aligned. The lateral projection distance of the slanted groove 58 is greater than the distance between the plug 56 and the slot 54.
[0047] Specifically, the upper end of the notch 41 is closed, and the adapter block 43 extends to the outside of the notch 41. During the movement of the insert block 56, the insert block 56 will never disengage from the slot 54. The inclined groove 58 drives the L-shaped rod 57 to move a sufficient distance to ensure that the insert block 56 can be inserted into the slot 54.
[0048] When in use, without the spray hood 14 installed, the insert 56 is not inserted into the slot 54. Under gravity, the connecting cylinder 12 always hangs downwards, thus preventing dust from falling onto the fan-shaped plate 35 and improving dust prevention. When the spray hood 14 is installed, first move the connecting cylinder 12 to rotate the adapter block 43 and make it abut against the inner wall of the notch 41. At this time, the insert, slot 54, and T-block are aligned. It is worth noting that you can hold the multi-directional bend 11 and use your thumb to move the adapter block 43 to avoid applying too much force when moving the connecting cylinder 12, which could cause all directions to move together. Then, when the push block 22 moves towards the inner groove 21 for the first time, it is driven by the arc-shaped plate 374... The transition block 43 moves in the direction of the transmission plate 52, causing the bearing plate 55 to move. With the cooperation of the inclined groove 58 and the L-shaped rod 57, the two insert blocks 56 are pushed towards the slot 54 until they are inserted into the slot 54. At this time, the transition block 43 and the multi-directional bend 11 cannot rotate. Thus, when the spray hood 14 is pulled, the multi-directional bend 11 moves together to make multi-angle adjustments. After the push block 22 pushes for the second time (that is, after the spray hood 14 is disassembled), the arc plate 374 is reset, and the bearing plate 55 is reset through the transmission. The insert blocks 56 leave the slot 54. At this time, the transition block 43 can be deflected again. Under the action of gravity, the connecting cylinder 12 is lowered again for dust prevention.
