Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an eye drops auxiliary device. Background Art

[0002] Chinese patent application number 201210255752.3 discloses a convenient and easy-to-use eye dropper, which includes two splints, a positioning plate and a pair of sliding inserts. The splints are installed on both sides of the positioning plates. A small hole for inserting the mouth of the eye drop bottle is provided in the center of the bottom of the positioning plate. The sliding insert is installed on the inner side of the splint and above the positioning plate. A long strip of clamping groove opening to the middle is provided in the middle of each sliding insert. The two open clamping grooves can form a closed notch. By adjusting the relative position of the two sliding inserts, the size of the closed notch formed by them can be changed, thereby meeting the clamping and fixing functions of eye drop bottles of different sizes.

[0003] In the above technical solution, the upper and lower eyelids are supported by the bottom of the splint, which makes it easier for patients to complete the process of instilling eye drops independently, and the bottleneck or bottle body of the eye drops is clamped by two sliding plugs that can slide relative to each other, thereby completing the fixation of the eye drops bottle. However, since the clamping grooves in the two sliding plugs are U-shaped, and the two sliding plugs slide against each other, only the length of the clamping groove can be changed, and the width of the clamping groove cannot be changed. Therefore, for eye drops bottles of different specifications, the adaptability of the above technical solution is low, resulting in the eye drops bottle being easily shaken during the process of squeezing the eye drops bottle with the splint, and it is difficult for patients to accurately drop the eye drops into the conjunctiva or conjunctival sac, which makes it difficult for patients to accurately instill eye drops using the above technical solution. Utility Model Content

[0004] The utility model aims to provide an eye drop auxiliary device which can be adapted to eye drop bottles of different specifications to ensure that the eye drops can be accurately dropped into the conjunctiva or the conjunctival sac.

[0005] To achieve the above-mentioned objectives, the utility model discloses an eye drop aid, comprising an elastic connecting plate and two splints symmetrically arranged on both sides of the elastic connecting plate, the splint comprising an upper part and a lower part, and under the action of external force, the upper parts of the two splints can move closer to each other, and the lower parts of the two splints can move away from each other, the upper part of the splint is located on the upper side of the elastic connecting plate, and the lower part of the splint is located on the lower side of the elastic connecting plate, a center hole is provided at the center position of the elastic connecting plate, the lower inner side of the splint is an arc structure adapted to the eye socket, the upper inner sides of the two splints are provided with protrusions symmetrically arranged with the center hole, and at least three elastic sheets are evenly distributed circumferentially around the center hole, the inner end of each elastic sheet is an arc surface and together encloses the center hole.

[0006] The upper parts of the two splints can be brought closer to each other and the lower parts of the two splints can be moved away from each other by deformation of the elastic connecting plate, or by hinged connection between the splints and the elastic connecting plate.

[0007] When the patient needs to put eye drops, the bottle body of the eye drop bottle is placed between the splints on both sides, the protrusion on the upper part of the splint is opposite to the bottle body of the eye drop bottle, and the lower part of the splint is against the eye socket of the patient's eye. The elastic sheet is pressurized by the eye drop bottle and bends downward and expands outward, thereby deforming the center hole. The center hole clamps the eye drop bottle, and then fixes the bottleneck of the eye drop bottle, thereby fixing the eye drop bottle in two dimensions (horizontal direction and axial direction of the eye drop bottle). When the patient pinches the outer sides of the two splints with his fingers and brings the upper parts of the two side splints closer to each other, a lever structure is formed between the splint and the elastic connecting plate, thereby separating the lower parts of the splints from each other, and the lower part of the splint opens the eyelids through its arc structure, thereby preventing the patient from blinking when putting eye drops, ensuring that the eye drops are accurately dropped into the center of the eyeball.

[0008] The utility model forms a center hole on the inner side of the elastic sheet that is adapted to the size of the bottleneck of the eye drops bottle, thereby fixing the bottleneck of the eye drops bottle, thereby fixing the eye drops bottle in two dimensions, preventing the bottle body of the eye drops bottle from shaking when squeezed by the protrusion on the splint, which makes it difficult to accurately drop the eye drops into the conjunctiva or conjunctival sac. The utility model has the advantage of being adaptable to eye drops bottles of different specifications to ensure that the eye drops can be accurately dropped into the conjunctiva or conjunctival sac.

[0009] Preferably, a horizontal concave structure is formed in the middle on at least one side of the connection between the elastic sheet and the elastic connecting plate.

[0010] By providing a horizontal concave structure at the connection between the elastic sheet and the elastic connecting plate, the structural strength of the elastic sheet can be reduced while ensuring the supporting performance of the elastic sheet, making it easier for patients to assemble and clamp the eye drops bottle.

[0011] Preferably, a horizontal concave structure is formed on both sides of the horizontal direction of the connection between the elastic sheet and the elastic connecting plate toward the middle, and the horizontal concave structure is arc-shaped, thereby further reducing the structural strength of the elastic sheet and ensuring the bending position of the elastic sheet; and the arc-shaped horizontal concave structure facilitates the flow of material during injection molding and is not prone to material shortage.

[0012] Preferably, a vertical concave structure is provided on the lower side of the connection between the elastic sheet and the elastic connecting plate.

[0013] By setting a vertical concave structure, it is possible to control the downward bending position of the elastic piece while reducing the structural strength of the elastic piece, so that the downward-bent elastic piece forms a barb-shaped structure, making it easier for the patient to insert the eye drop bottle into the central hole, and increasing the resistance when the eye drop bottle is separated from the elastic piece, facilitating the patient to assemble and clamp the eye drop bottle.

[0014] When both a horizontal concave structure and a vertical concave structure are provided between the elastic pieces, it further realizes limiting the downward bending position of the elastic piece while ensuring the supporting performance of the elastic piece, so that the downward-bent elastic piece forms a barb-shaped structure, making it easier for the patient to insert the eye drop bottle into the central hole, and increasing the resistance when the eye drop bottle is separated from the elastic piece, facilitating the patient to assemble and clamp the eye drop bottle, preventing the eye drop bottle from axially moving, and facilitating the patient to assemble and clamp the eye drop bottle.

[0015] Preferably, the upper parts of the two clamping plates are inclined outward.

[0016] The upper parts of the clamping plates are inclined outward to form an open structure, facilitating the patient to apply force, and providing a larger space during the installation of the eye drop bottle compared to the way the two side clamping plates are parallel.

[0017] Preferably, the length of the upper part of the clamping plate is greater than the length of the lower part of the clamping plate.

[0018] In the case of forming a lever structure between the clamping plate and the elastic connecting plate, the upper part of the clamping plate serves as the power arm, and the lower part of the clamping plate serves as the resistance arm. The setting method where the length of the upper part of the clamping plate is greater than the length of the lower part of the clamping plate can make it easier for the patient.

[0019] Preferably, the manufacturing materials of the elastic connecting plate and the clamping plate are both medical silica gel, so that it is convenient for the patient to deform the elastic connecting plate through the two side clamping plates; using the characteristics of medical silica gel itself, it is non-irritating, non-toxic, and non-allergic to human tissues, and can ensure the safety of the patient during use compared to iron or wooden materials.

[0020] Preferably, a groove structure symmetrically arranged with the two clamping plates is provided on the lower side of the elastic connecting plate, and the concave structure can make the elastic connecting plate easier to deform.

[0021] Through the groove structure on the lower side of the elastic connecting plate, the deformation mode and deformation position of the elastic connecting plate are limited, and the resistance during the deformation of the elastic connecting plate is reduced, facilitating the patient to clamp through the two side clamping plates of the elastic connecting plate.

[0022] Preferably, the protrusion is located at the central position in the horizontal direction inside the clamping plate. The protrusion has a horizontally placed U-shaped structure, the bottom of the protrusion is arc-shaped, and one end where the two protrusions are close to each other is a rounded chamfered structure.

[0023] The protrusions located on the inner sides of the clamping plates are used to ensure effective extrusion of the eye drop bottle body when the two clamping plates approach each other, and can prevent the protrusions from damaging the bottle body of the eye drop bottle through the arc-shaped chamfered structure when squeezing the bottle body of the eye drop bottle, thus affecting its subsequent service life.

[0024] Preferably, the overall horizontal direction of the clamping plates is in a curved structure, which can ensure the structural strength of the two clamping plates during the clamping process and prevent deformation of themselves, resulting in failure.

[0025] The utility model can fix the eye drop bottle by forming a central hole on the inner side of the elastic sheet that is adapted to the bottleneck size of the eye drop bottle and forming a barb-shaped structure after the elastic sheet is bent downward, thereby preventing the bottle body of the eye drop bottle from shaking or axially moving when being squeezed by the protrusions on the clamping plates, and having the advantage of ensuring the accuracy of the dripping position of the eye drops.

[0031] The following further describes the utility model according to the drawings and specific embodiments.

[0032] As shown by Figure 1 , this embodiment discloses an eye drop assisting device, including an elastic connecting plate 11 and clamping plates 12 symmetrically arranged on both sides of the elastic connecting plate 11. The elastic connecting plate 11 and the clamping plates 12 are of an integrated design. The overall horizontal direction of the clamping plates 12 is in a curved structure. The elastic connecting plate 11 is of an oval structure. A groove 17 arranged along the length direction of the elastic connecting plate 11 is formed on the lower side of the elastic connecting plate 11. The materials of the elastic connecting plate 11 and the clamping plates 12 are both medical silica gel. The two clamping plates 12 are of an open-top structure from bottom to top. As shown by Figure 2As shown, the splint 12 includes an upper part 121 and a lower part 122. The upper part 121 of the splint 12 is located above the elastic connecting plate 11, and the lower part 122 of the splint 12 is located below the elastic connecting plate 11. The lower part 122 of the splint 12 is in an arc-shaped structure adapted to the eye socket, thus facilitating abutting against the eye socket of the patient's eye. The length of the upper part 121 of the splint 12 is greater than the length of the lower part 122 of the splint 12. A central hole 15 is provided in the elastic connecting plate 11. At least three elastic pieces 14 are circumferentially and evenly distributed around the central hole 15. The inner ends of each elastic connecting plate 11 are all in an arc surface and jointly enclose the central hole 15. An arc-shaped cavity 16 is provided between the roots of two adjacent elastic pieces 14, so that the central hole 15 is a cavity in a plum blossom shape. Arc-shaped grooves 18 with openings downward are provided at the lower ends of the elastic pieces 14. The arc-shaped grooves 18 jointly form a complete circle, and the arc-shaped grooves 18 are adapted to the arc tops in the circumferential direction of the arc-shaped cavity 16.

[0033] As shown by Figure 3 and Figure 4 shown, the bottleneck of the eye drops bottle 20 is passed through the central hole 15 formed by the arc surfaces at the inner ends of the elastic pieces 14. The elastic pieces 14 bend downward at the arc-shaped grooves 18 at the lower ends of the elastic pieces 14 (i.e., at the arc tops in the circumferential direction of the arc-shaped cavity 16). The bent-down elastic pieces 14 form an inverted hook-shaped structure, making it more labor-saving for the patient to insert the eye drops bottle 20 into the central hole 15 and increasing the resistance when the eye drops bottle 20 is separated from the elastic pieces 14, facilitating the patient to assemble and clamp and fix the eye drops bottle 20.

[0034] Protrusions 13 symmetrically arranged with respect to the central hole 15 are provided on the upper parts 121 of the two splints 12. When the two splints 12 approach each other, the protrusions 13 are used to abut against the bottle body of the eye drops bottle 20, ensuring that the two splints 12 can clamp the bottle body of the eye drops bottle 20 to a deformed degree. The mutually approaching ends of the two protrusions 13 are in an arc-shaped chamfered structure to prevent the protrusions 13 from damaging the bottle body of the eye drops bottle 20 and affecting its subsequent service life.

[0035] When the patient needs to apply eye drops, the bottle body of the eye drop bottle 20 is placed between the two side splints 12 and the bottle body of the eye drop bottle 20 is passed through the elastic connecting plate 11. The elastic sheet 14 bends downward and expands relatively, forming a central hole 15 on the inner side that matches the size of the bottleneck of the eye drop bottle 20, thereby fixing the bottleneck of the eye drop bottle 20. The lower part 122 of the splint 12 is against the eye socket of the patient's eye. When the patient brings the upper parts 121 of the two side splints 12 closer, the groove 17 causes the elastic connecting plate 11 to fold at a small angle, and the upper part of the splint 12 The protrusion 13 of the part 121 squeezes the bottle body of the eye drops bottle 20, thereby increasing the pressure inside the bottle body of the eye drops bottle 20, and causing the eye drops to drip. In this process, due to the lever structure formed between the splint 12 and the elastic connecting plate 11, the lower parts 122 of the splint 12 are moved away from each other, and the lower part 122 of the splint 12 opens the eyelids through its arc structure, thereby preventing the patient from blinking when dripping eye drops, thereby achieving the eye drops bottle 20 being fixed in two dimensions during the dripping process of the eye drops, thereby ensuring the accuracy of the eye drops dripping.
