Description

Technical Field

[0001] The invention relates to ophthalmic medical auxiliary equipment, in particular to an auxiliary tool for quantitative dripping of eye drops. Background Art

[0002] In the field of ophthalmology, eye drops are a common and effective treatment method, widely used to treat and alleviate symptoms of various eye diseases. Eye drops are typically packaged in plastic bottles, and the solution is manually squeezed to release the liquid into the eye. However, this traditional method of use has several limitations, particularly regarding dosage control and ease of use, causing significant inconvenience for some patients.

[0003] The use of eye drops often requires strict dosage control. Different diseases and patients have different requirements for the dosage of eye drops. Too much or too little drops may affect the therapeutic effect. For example, excessive use may lead to drug waste or increase the risk of side effects, while insufficient drops may not achieve the desired therapeutic effect. However, manually squeezing the eye drop bottle makes it difficult to accurately control the amount of drops each time, especially for people with poor hand coordination (such as the elderly, arthritis patients or those with hand dysfunction). These patients often find it difficult to control the appropriate force when squeezing the bottle, resulting in too much or too little liquid being squeezed out, and may even contaminate the liquid or damage eye tissue due to improper operation.

[0004] Therefore, designing a versatile, easy-to-use, and low-cost auxiliary device that can be adapted to existing eye drop bottles and achieve precise drop control is of great practical significance. This device can not only improve the efficiency of eye drop use and reduce drug waste, but also significantly improve the patient experience, especially for people with poor hand coordination. Summary of the Invention

[0008] Preferably, the button structure is further provided with an elastic reset member, which is connected to the button structure and the cylindrical shell at the same time, and the elastic reset member acts on the button structure in an automatic reset direction toward the outside of the cylindrical shell.

[0009] Preferably, the rear end of the cylindrical shell is provided with a bottom plate, and the bottom jack is provided on the bottom plate, and the insertion direction of the bottom jack corresponds to the inner side of the pressure plate; the adjusting piece includes an inserting piece and a fixing piece, and the inserting piece and the fixing piece are fixedly connected to each other vertically; after the first adjusting piece is inserted, the inserting piece enters the inner side of the pressure plate, and the fixing piece is docked and fixed on the bottom plate; the inserting pieces of the adjusting pieces inserted subsequently in sequence are abutted against the outer wall of the previous inserting piece, and the fixing pieces of the adjusting pieces inserted subsequently in sequence are docked and fixed on the outer wall of the previous fixing piece.

[0010] Preferably, the fixing plate is magnetically connected to the base plate, and the fixing plates stacked on each other are magnetically connected to each other.

[0011] Preferably, the fixing plate is provided with an easy-to-remove structure, and the easy-to-remove structure is configured as an edge notch formed by the inward depression of the fixing plate, the edge notch penetrates to the inner wall of the fixing plate but does not penetrate to the outer wall of the fixing plate, the edge notch of the innermost fixing plate and the bottom plate form a space for picking up with fingers, and the edge notch of the stacked rear fixing plate and the previous fixing plate form a space for picking up with fingers.

[0012] Preferably, the elastic return member includes a spring sheet, one end of which is fixedly connected to the cylindrical housing, and the other end of which is fixedly connected to the external button, and the spring sheet provides an outward elastic force for the external button.

[0016] Compared with the existing technology, the eye drops quantitative drip auxiliary tool using the above technical solution has the following beneficial effects: First, a quantitative eye drop dripping auxiliary tool is provided. Through the combination of a sleeve body, a limit button mechanism, and a liquid output adjustment mechanism, it achieves quantitative squeezing and drip control of the eye drop bottle. The sleeve body is adapted to the eye drop bottle, and its mounting compartment can effectively secure and wrap the eye drop bottle, ensuring the stability of the eye drop bottle during use. The button structure is restricted by the limit structure, and each press can only advance a fixed distance. This ensures that the force of each press is consistent, driving the pressure plate to squeeze the eye drop bottle to control the drip volume each time. This solves the problem of difficult to control the drip volume when manually squeezing the eye drop bottle with traditional eye drops. It is particularly suitable for people with poor hand coordination.

[0017] Second, the liquid volume adjustment mechanism is designed to further adjust the amount of liquid delivered each time. By inserting different numbers of adjustment pieces, the gap between the pressure plate and the eye drop bottle can be adjusted. Each time an adjustment piece is added, the degree of compression increases by one level, thereby increasing the amount of liquid delivered in a single squeeze. This design allows for quantitative adjustment of the liquid volume to meet the needs of different patients.

[0018] 3. The magnetic connection design between the fixing plate and the base plate, as well as between the fixing plates, makes the installation and removal of the adjustment plate more convenient. No additional structure or fixing device is required, which simplifies the installation and removal process of the adjustment plate, improves the ease of use of the adjustment plate, and makes the installation simple and reliable. The design of the easy-to-remove structure on the edge of the fixing plate makes the removal of the adjustment plate more convenient. The user can easily remove the adjustment plate without the help of tools.

[0019] Fourth, the elastic return member can provide an outward elastic force for the button structure, ensuring that the button structure can be quickly reset after each press, preventing the elastic force of the eye drops bottle itself from being unable to push out the button structure, facilitating the next pressing operation; the spring sheet specifically used in the elastic return member has the advantages of simple structure and stable rebound effect.

[0020] 5. Limit button mechanisms are set on both sides of the cylindrical shell. At the same time, the design of the bottom socket and the adjustment piece enables the plug to be inserted into the two bottom sockets at the same time, which can ensure the synchronization of the extrusion degree on both sides, ensure the consistency of the extrusion force on both sides, and improve the uniformity of each extrusion drip.

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] like Figures 1 to 6 The illustrated eye drop metered delivery aid comprises a sleeve body 2 for use with an eye drop bottle 1. The sleeve body 2 includes a cylindrical outer shell 3, a limit button mechanism 4 disposed on the cylindrical outer shell 3, and a liquid delivery adjustment mechanism. The limit button mechanism 4 comprises two sets, one on each side of the cylindrical outer shell 3. The cylindrical outer shell 3 defines a mounting compartment 30 for receiving the eye drop bottle 1. The mounting compartment 30 extends through the front end of the cylindrical outer shell 3 and forms an opening for the eye drop bottle 1 to enter and exit. A bottom plate 31 is provided at the rear end of the cylindrical outer shell 3. An anti-slip structure is also provided within the cylindrical outer shell 3. The anti-slip structure comprises two curved pads 32 fixed to the inner wall of the mounting compartment 30 and positioned between the two sets of limit button mechanisms 4. The curved pads 32 are made of an elastic material, specifically rubber or silicone. When the eye drop bottle 1 is inserted into the mounting compartment 30, the curved pads 32 adhere tightly to and tighten against the outer wall of the eye drop bottle 1.

[0030] The limit button mechanism 4 includes a button structure 40 and a limit structure 42. The button structure 40 is disposed throughout the cylindrical housing 3. A pressure plate 41 is connected to the button structure 40 for contacting and pressing the eye drop bottle 1. The pressure plate 41 is located in the mounting compartment 30. The limit structure 42 limits the pressing stroke of the button structure 40 to a fixed stroke. The button structure 40 includes an external button 400 and a button rod 401. The external button 400 is located on the outer wall of the cylindrical housing 3. The cylindrical housing 3 has a sliding hole. The button rod 401 engages and slides with the sliding hole. The pressure plate 41 is fixedly connected to the inner end of the button rod 401.

[0031] The limiting structure 42 is configured to include an outer edge stopper 420 and a limiting stopper 421, wherein: The outer edge baffle 420 is formed by the edge of the external button 400 extending beyond the button rod 401; the limit stop 421 is formed by the outer edge of the sliding hole; after the external button 400 is pressed and pushed inward to a fixed stroke, the outer edge baffle 420 is blocked by the limit stop 421 to prevent the button structure 40 from continuing to advance, so that the pressing stroke of the button structure 40 is fixed.

[0032] The button structure 40 is also provided with an elastic reset member, which includes a spring sheet. One end of the spring sheet is fixedly connected to the cylindrical shell 3, and the other end is fixedly connected to the external button 400. The spring sheet provides an outward elastic force for the external button 400. The spring sheet acts on the button structure 40. After one press, it can ensure that the button structure 40 can be quickly reset, avoiding the elastic force of the eye drops bottle 1 itself from being unable to push out the button structure 40, facilitating the next pressing operation.

[0033] The liquid output adjustment mechanism includes a bottom jack 310 and a stacking plate assembly 5. Two bottom jacks 310 are provided. Both bottom jacks 310 are located at the rear end of the cylindrical housing 3 and extend through the mounting compartment 30. The two bottom jacks 310 correspond to the pressure plates 41 of the two sets of limit button mechanisms 4, and the insertion orientation of the two bottom jacks 310 is biased toward the inner side of the pressure plates 41 on either side. The stacking plate assembly 5 includes multiple adjustment plates 50 that can be stacked and inserted into the jacks. The adjustment plates 50 include two inserting plates 500 and a fixing plate 501. The two inserting plates 500 are fixedly connected to each other on either side of the fixing plate 501, and the inserting plates 500 and the fixing plate 501 are perpendicular to each other. The spacing between the two inserting plates 500 on either side of the fixing plate 501 allows them to be inserted into both bottom jacks 310 simultaneously. The fixing plates 501 are magnetically connected to the bottom plate 31, and the stacked fixing plates 501 are also magnetically connected to each other. After the first adjusting piece 50 is inserted, the inserting pieces 500 on both sides respectively enter the inner sides of the pressure plates 41 on both sides and are inserted between the pressure plates 41 and the eye drops bottle 1. At the same time, the fixing piece 501 of the adjusting piece 50 is magnetically fixed to the bottom plate 31. The inserting pieces 500 of the adjusting pieces 50 inserted subsequently are abutted against the outer wall of the previous inserting piece 500. The superimposed inserting pieces 500 are always located between the pressure plate 41 and the eye drops bottle 1. The fixing pieces 501 of the adjusting pieces 50 inserted subsequently are magnetically fixed to the outer wall of the previous fixing piece 501. The fixing plate 501 is provided with an easy-to-remove structure, which is configured as an edge notch 502 formed by the inward depression of the fixing plate 501. The edge notch 502 penetrates the inner wall of the fixing plate 501 but does not penetrate the outer wall of the fixing plate 501. The edge notch 502 of the innermost fixing plate 501 and the bottom plate 31 form a space for fingers to pick up. The edge notch 502 of the stacked rear fixing plate 501 and the previous fixing plate 501 form a space for fingers to pick up.

[0034] How to use: First, align the rear end of the eye drops bottle 1 with the opening and insert it into the installation compartment 30, so that the eye drops bottle 1 is tightened and fixed by the arc-shaped pad 32; then hold the cylindrical shell 3, and place the thumb and the other finger on the external buttons 400 on both sides respectively; when dripping, use your fingers to press the external buttons 400 on both sides, and press the external buttons 400 until you can no longer press them. At this time, the eye drops bottle 1 is squeezed and deformed to a fixed degree, and a drip is performed; the subsequent dripping can continue with the above steps.

[0035] If you need to increase the amount of liquid dripped out in a single time, take the required number of adjustment plates 50 according to actual needs, stack the adjustment plates 50 at a time and insert them into the bottom socket 310 of the bottom plate 31, press the fixing plate 501 toward the bottom plate 31 and compact it, so that the fixing plate 501 is magnetically fixed to the bottom plate 31 and the stacked fixing plates 501, and then press the external buttons 400 on both sides to start dripping.

[0036] If the amount of liquid dripped out at a time needs to be reduced, the required number of adjustment pieces 50 can be pulled out in sequence according to actual needs, and then the external buttons 400 on both sides can be pressed to drip the liquid.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
