Description

Technical Field

[0001] This invention specifically relates to a neonatal ocular drug delivery dropper. Background Technology

[0002] Ocular drug administration is a common but highly challenging procedure in the clinical care of newborns, especially premature infants. Due to their physiological and psychological immaturity, newborns commonly experience problems such as "fear of the procedure" and "difficulty in achieving precision" that current technologies have not effectively addressed.

[0003] Specifically, current clinical practice primarily relies on traditional eye drop bottles or graduated droppers for ocular medication administration. Traditional eye drop bottles control the flow of medication by squeezing the bottle, resulting in inconsistent droplet size and a high risk of overdosing or underdosing due to inaccurate dosage. More importantly, the sudden approach of the bottle and the physical impact of the droplet on the eyeball can directly trigger the innate startle reflex in newborns, causing crying and head shaking, leading not only to administration failure but also the risk of instrument-induced eye damage. While graduated droppers allow for rough measurement, the process of transferring the medication into the dropper significantly increases the risk of contamination. Furthermore, the direct proximity and impact on the eye during instillation is still unavoidable. In addition, while some existing mechanical instillation devices use springs or pistons to achieve quantitative dispensing, their design focus remains limited to addressing measurement issues and fails to address the core clinical pain points caused by fear and non-cooperation in children. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a neonatal eye medication dropper that can accurately and quantitatively administer medication, greatly reduce the difficulty of operation, avoid startling newborns, and reduce the risk of cross-infection.

[0005] To achieve the above objectives, the present invention provides a neonatal ocular drug delivery instillation device, comprising: The storage device includes a main storage tank and a single-volume storage tank. The main storage tank is used to supply the liquid medicine to the single-volume storage tank. The bottom of the single-volume storage tank is provided with a medicine outlet pipe communicating with its inner cavity. A drug delivery actuator is used to slowly expel the liquid medicine from the single-volume storage tank from the dispensing tube, and then draw the liquid medicine from the main storage tank into the single-volume storage tank; A vision distraction system, disposed on the single-volume storage container and located near the eye, is used to distract the child's attention from the eyes during drug administration; and The first linkage mechanism is connected to the drug delivery execution mechanism and the visual distraction system, so that the visual distraction system is triggered to start when the drug delivery execution mechanism performs drug dispensing.

[0006] Furthermore, the drug delivery actuator includes a linear motion drive source, a push rod, and a piston plate. The piston plate is slidably and sealed within the single-volume storage tank. The push rod is fixed to the piston plate and slidably extends from the top of the single-volume storage tank. The linear motion drive source is used to drive the push rod to move up and down.

[0007] Furthermore, the linear motion drive source includes a slow-rotating power source, a cam, a push plate, and an elastic support. The push plate is disposed at the top of the push rod, and the elastic support is supported between the push plate and the single-volume storage tank. The cam is located above the push plate, and the outer edge of the cam is vortex-shaped. The outer edge of the cam contacts the upper surface of the push plate. The slow-rotating power source is used to drive the cam to rotate, and during the rotation of the cam, it can push the push plate to move downward.

[0008] Furthermore, the slow-speed rotating power source includes a manual handle, a driving rotating shaft, a driving gear, a reduction gear set, and a driven gear. The driving rotating shaft is rotatably mounted on the top of the main storage tank via a bracket. The driving gear is sleeved and fixed on the driving rotating shaft. The manual handle is fixed on the driving rotating shaft, and the user drives the driving rotating shaft to rotate via the manual handle. The driven gear is sleeved and fixed on the main shaft of the cam. The reduction gear set meshes between the driving gear and the driven gear, and the transmission ratio of the reduction gear set is greater than 1.

[0009] Furthermore, the vision dispersion system includes a rotating disk with multiple black and white patterns on the side facing the human body. The rotating disk is rotatably fitted around the outer periphery of the single-volume storage tank. The first linkage mechanism is connected between the active rotating shaft and the rotating disk. When the active rotating shaft rotates, the rotating disk is driven to rotate through the first linkage mechanism.

[0010] Furthermore, the first linkage mechanism includes a transmission chain assembly and a transmission gear set. The transmission gear set is disposed on the single-quantity storage tank and is connected to a gear disposed on the rotating disk through the transmission chain assembly. When the active rotating shaft rotates, the transmission chain assembly and the transmission gear set drive the rotating disk to rotate around the single-quantity storage tank.

[0011] Furthermore, the drug delivery mechanism also includes a capillary drop head, which is connected to the bottom end of the drug delivery tube and communicates with the drug delivery tube. The outlet end of the capillary drop head is provided with a plurality of micron-sized pores communicating with its inner cavity.

[0012] Furthermore, the pore size of the capillary droplet head is 5-50 micrometers.

[0013] Furthermore, it also includes an atomizing airflow generating mechanism, which is disposed on the drug outlet tube and is used to atomize the drug liquid entering and exiting from the capillary drop head by means of airflow.

[0014] Furthermore, the atomizing airflow generating mechanism includes a micro fan and a second linkage mechanism. The micro fan is mounted on the drug dispensing tube, and the second linkage mechanism includes an internal gear and an external gear. The internal gear is connected to the power output shaft of the transmission gear set, and the external gear is sleeved and fixed on the rotating shaft of the micro fan and meshes with the internal gear. When the active rotating shaft rotates, the drug dispensing mechanism simultaneously rotates the rotating shaft of the micro fan. The airflow generated by the micro fan can blow across the surface of the capillary droplet head and guide it to the eye.

[0015] The beneficial effects of this invention are: The above-mentioned neonatal ocular drug delivery dropper has at least the following advantages: 1. By setting up a single-volume storage tank with a fixed volume, a precise measurement benchmark is provided for each dose, fundamentally overcoming the problem of uneven dosage caused by traditional hand-held medicine bottles, ensuring the accuracy and consistency of drug administration, and effectively avoiding the safety hazards caused by overdose or underdose.

[0016] 2. By setting up a linkage mechanism, the drug delivery mechanism is linked with the visual distraction system, so that the soothing system is triggered at the same time as the drug dispensing action is started. This ensures that the newborn's attention can be effectively attracted and distracted during the critical time of drug dispensing, thereby greatly reducing the startle reflex and crying caused by the proximity of the device and discomfort, and improving the child's cooperation and the success rate of nursing operations.

[0017] 3. By integrating precise drug administration and visual comfort into one function, a single operation triggers dual effects. Nursing staff no longer need to perform medication administration and comforting steps separately, simplifying the procedure, reducing the skill requirements for the operator, and making the nursing process smoother and more efficient.

[0018] 4. Through the "drug dispensing-replenishing" cycle design, the device can automatically prepare for the next administration after one operation is completed, ensuring dosage stability and operational continuity when multiple or bilateral administrations are required, which is particularly suitable for busy clinical nursing environments.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 4 The present invention provides a neonatal ocular drug delivery dropper, comprising a storage device 100, a drug delivery execution mechanism 200, a vision distraction system 300, and a first linkage mechanism 400.

[0023] Specifically, the storage device 100 includes a main storage tank 110 and a single-volume storage tank 120. The main storage tank 110 serves as a medicine reservoir, supplying medicine to the single-volume storage tank 120. The single-volume storage tank 120 has a dispensing pipe at its bottom, the core function of which is to achieve precise measurement of a single dose. By limiting the fixed volume of the single-volume storage tank 120, the consistent volume of medicine dispensed each time is fundamentally guaranteed, overcoming the problem of uneven dosage caused by traditional hand-held medicine bottles.

[0024] In practice, the main storage tank 110 and the single-volume storage tank 120 can be fixed together by a connecting frame. During operation, the eye drops can be instilled by holding the main storage tank 110 or the single-volume storage tank 120.

[0025] The drug delivery device 200 is responsible for slowly squeezing the liquid medicine in the single-volume storage tank 120 from the dispensing tube; secondly, after the squeezing is completed, the drug delivery device 200 is responsible for drawing the liquid medicine in the main storage tank 110 into the single-volume storage tank 120 to prepare for the next drug delivery, realizing the "squeezing-replenishing" cycle, ensuring the convenience of continuous use and the stability of dosage.

[0026] The visual distraction system 300 is positioned on the side of the single-dose storage container 120 near the child's eyes. It is used to actively attract and distract the child's attention during crucial moments when medication may cause the child to become anxious and cry.

[0027] The first linkage mechanism 400 is connected to the drug delivery execution mechanism 200 and the visual distraction system 300. When the user activates the drug delivery execution mechanism 200 to dispense the medication, this action will forcibly and synchronously trigger the visual distraction system 300 through the first linkage mechanism 400. This ensures that the soothing and therapeutic actions are completely synchronized in time, guaranteeing that the child's attention has been successfully diverted the moment the medication is dispensed, thereby greatly reducing the startle reflex caused by the proximity of the device and discomfort.

[0028] In this embodiment, the drug delivery actuator 200 includes a linear motion drive source 210, a push rod 220, and a piston plate 230. The piston plate 230 is sealed and slidably disposed within the single-volume storage tank 120, and the push rod 220 is fixed to the piston plate 230 and slidably extends out of the top of the single-volume storage tank 120. The linear motion drive source 210 is used to drive the push rod 220 to perform vertical linear motion.

[0029] In operation, when the linear motion drive source 210 pushes the push rod 220 downward, the piston plate 230 descends accordingly, applying steady pressure to the liquid medicine in the single-volume storage tank 120, forcing it to be discharged from the dispensing pipe. When the drive source drives the push rod 220 upward, the piston plate 230 rises, creating a negative pressure in the single-volume storage tank 120, thereby automatically drawing a measured amount of liquid medicine from the main storage tank 110. This completes the automatic liquid replenishment process.

[0030] A preferred embodiment of the linear motion drive source 210 includes a slow-rotating power source 211, a cam 212, a pusher plate 213, and an elastic support 214. The pusher plate 213 is positioned at the top of the push rod 220, and the elastic support 214 (such as a compression spring) is supported between the pusher plate 213 and the housing of the single-volume storage tank 120. The cam 212 is located above the pusher plate 213, and its outer edge is spiral-shaped, contacting the upper surface of the pusher plate 213. The slow-rotating power source 211 drives the cam 212 to rotate.

[0031] In operation, initially, the short-diameter end of cam 212 contacts push plate 213. As cam 212 rotates under the drive of the power source, its long-diameter end gradually presses down on push plate 213 according to its contour changes, compressing elastic support member 214. This, in turn, pushes piston plate 230 downwards slowly via push rod 220, completing the drug extrusion action. When cam 212 continues to rotate to the end of its long-diameter rotation, push plate 213 detaches from its long-diameter end. Under the release of elastic force from the compressed elastic support member 214, push plate 213 is driven to rise rapidly and re-contact the short-diameter end, simultaneously completing the drug suction process.

[0032] This method has the following advantages: 1. The profile of cam 212 makes the extrusion process extremely slow and smooth, achieving true "gentle drug delivery"; 2. The use of elastic support 214 to achieve automatic reset can quickly complete drug absorption and prepare for the next extrusion.

[0033] In this embodiment, the slow-rotating power source 211 includes a manual handle 2111, an active rotating shaft 2112, an active gear 2113, a reduction gear set 2114, and a driven gear 2115. The active rotating shaft 2112 is rotatably mounted on the top of the main storage tank 110 via a bracket. The active gear 2113 is sleeved and fixed on the active rotating shaft 2112. The manual handle 2111 is fixed on the active rotating shaft 2112. The user drives the active rotating shaft 2112 to rotate by the manual handle 2111. The driven gear 2115 is sleeved and fixed on the main shaft of the cam 212. The reduction gear set 2114 meshes between the active gear 2113 and the driven gear 2115. The transmission ratio of the reduction gear set 2114 is greater than 1.

[0034] During use, the user's manual rotation of the handle 2111 is significantly slowed down and the torque increased after passing through the reduction gear set 2114 before being output to the cam 212. This makes the rotation speed of the cam 212 very slow, thus ensuring a slow and uniform extrusion process.

[0035] The deceleration mechanism ensures that the piston plate 230 descends smoothly, pushing the liquid in the liquid chamber out of the outlet at a uniform speed and smoothly, while preventing instantaneous large-dose administration due to operational errors.

[0036] In this embodiment, the vision distraction system 300 includes a rotating disk rotatably fitted around the periphery of the single-volume storage tank 120. The side of the rotating disk facing the child is decorated with a high-contrast black and white pattern (such as a bullseye or black and white stripes). A first linkage mechanism 400 is connected between the active rotation shaft 2112 and the rotating disk.

[0037] The first linkage mechanism 400 includes a transmission chain assembly 410 and a transmission gear set 420. The transmission gear set 420 is disposed in the single quantity storage tank 120 and is connected to the gears disposed on the rotating disk through the transmission chain assembly 410. When the active rotating shaft 2112 rotates, the rotating disk is driven to rotate around the single quantity storage tank 120 through the transmission chain assembly 410 and the transmission gear set 420.

[0038] During use, as the medication is slowly dispensed, the newborn will see a slowly rotating black and white pattern in front of their eyes. Newborns have an innate ability to track high-contrast, slowly moving objects, and they are most sensitive to black and white contrasts. The rotating disc effectively attracts and maintains their attention, causing them to ignore the dripper itself and any potential slight discomfort, thus alleviating the newborn's "fear of manipulation."

[0039] In a preferred embodiment, the actuator further includes a capillary drip head, which is connected to the bottom end of the drug outlet tube and communicates with the drug outlet tube. The outlet end of the capillary drip head is provided with a plurality of micron-sized pores communicating with its inner cavity, preferably 5-50 microns in diameter.

[0040] During use, as the medication flows to the capillary droplet head under the piston's thrust, it seeps out from its numerous micropores, forming dozens of extremely fine streams. Due to surface tension, these streams naturally break into even finer droplets, creating a "drizzle" or "mist" effect. Compared to the impact of a single droplet, this significantly reduces the physical irritation of the medication to the delicate ocular surface of newborns, making the medication administration experience much gentler.

[0041] To achieve better atomization, this embodiment also includes an atomizing airflow generating mechanism 500. The atomizing airflow generating mechanism 500 includes a miniature fan 510 and a second linkage mechanism 520. The miniature fan 510 is mounted on the drug dispensing tube. The second linkage mechanism 520 includes an internal gear 521 and an external gear 522. The internal gear 521 is connected to the power output shaft of the transmission gear set 420. The external gear 522 is sleeved and fixed on the rotating shaft of the miniature fan 510 and meshes with the internal gear 521. When the active rotating shaft 2112 rotates, the drug dispensing execution mechanism 200 simultaneously triggers the rotating shaft of the miniature fan 510 to rotate. The airflow generated by the miniature fan 510 can blow across the surface of the capillary droplet head and guide it to the eye.

[0042] When the user turns the handle, the miniature windmill 510 rotates synchronously through the power transmission of the first linkage mechanism 400 and the second linkage mechanism 520, generating a gentle airflow. This airflow blows across the surface of the capillary droplet head, further breaking up and dispersing the liquid medicine seeping from the micropores, forming a finer medicinal mist.

[0043] This method has the following advantages: 1. With airflow-assisted atomization, the drug particles are finer and more evenly distributed, which is conducive to absorption; 2. The medication mist floats on the surface of the eye, completely eliminating the impact of droplets, further helping to alleviate irritation to newborns, facilitating medication application and ensuring accurate injection of the medication solution.

[0044] The method of using this neonatal ocular medication instillation device mainly includes four stages: preparation, positioning, execution, and resetting. The specific operating steps are as follows: Step 1: Preparing and filling the medicine solution Inspection and Installation: Ensure the device is clean. If this is the first time using the device or if the solution needs to be changed, add the appropriate amount of the specified eye drops to the main storage tank 110. Confirm that the connecting pipe between the individual storage tank 120 and the main storage tank 110 is unobstructed.

[0045] Initial reset: Turn the manual handle 2111 until you feel a noticeable "click" or the resistance becomes lighter. This indicates that the internal cam 212 has rotated from its long diameter end to its short diameter end, the piston plate 230 is in its highest position under the action of the elastic support 214, the single-volume storage tank 120 has automatically drawn a fixed amount of medicine from the main storage tank 110 through negative pressure, and the device is in the state of ready to administer medicine.

[0046] Step Two: Positioning and Pre-Reassurance Holding and securing: Hold the newborn in a stable position and gently secure their head.

[0047] Instrument positioning: Holding the main storage container 110 or connecting holder of the drip set, move the device to the newborn's eyes. Position the tip of the drip set, equipped with the black and white rotating disc, approximately 2 to 3 centimeters directly in front of the newborn's eyes, ensuring the capillary droplet tip is roughly aligned with the eyelid slit. Take care to avoid direct contact between the instrument and the eye.

[0048] Step 3: Perform simultaneous drug administration and soothing. Slowly open the newborn's upper and lower eyelids with two fingers (in practice, a commonly available eyelid opener can be used to open the newborn's upper and lower eyelids, freeing up one hand for operation), then slowly and evenly rotate the manual handle 2111. This single operation will simultaneously trigger the following three actions: a) Precise metering and slow dispensing: The rotational power of the manual handle 2111 is transmitted to the cam 212 through the active rotating shaft 2112 and the reduction gear set 2114. The scroll profile of the cam 212 begins to slowly press down on the push plate 213 with its long diameter end, pushing the piston plate 230 to descend smoothly, and uniformly dispensing the metered amount of medicine in the single-volume storage tank 120.

[0049] b) Visual attention distraction: At the same time, the power of the active rotating shaft 2112 is transmitted to the rotating disk through the first linkage mechanism 400 (i.e., the transmission gear set 420 and the transmission chain assembly 410), driving the rotating disk with black and white patterns to start rotating slowly, thereby attracting and maintaining the newborn's visual attention.

[0050] c) Airflow-assisted atomization: Simultaneously, through the second linkage mechanism 520 (e.g., another set of gear transmissions), the rotational power of the manual handle 2111 also drives the micro windmill 510 to start rotating. The gentle airflow generated by the micro windmill 510 blows directly towards the outlet end of the capillary droplet head.

[0051] Gentle drug delivery is achieved: the medication seeping from the micro-orifices of the capillary dropper is first dispersed into fine streams, then further broken up by the airflow generated by the miniature windmill 510, forming a fine mist that is carried by the wind to the newborn's eyes, achieving gentle, non-impact immersion drug delivery. Throughout the process, the newborn will be attracted by the slowly rotating black and white patterns in front of their eyes, effectively distracting them from any discomfort or fear associated with the drug administration itself.

[0052] Step 4: Reset and Subsequent Operations Under the strong force of the elastic support, it quickly resets and rises, driving the piston plate 230 upward, thereby generating negative pressure in the single-volume storage tank 120, automatically drawing the next dose of medicine from the main storage tank 110, and preparing for the next administration.

[0053] To care for the other eye or to finish: If you need to care for the other eye, repeat steps two through four. After all care is complete, store the device properly in a clean place.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
