Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an eye medication applicator. Background Technology

[0002] In the medical field, the treatment of eye diseases often requires patients to apply medication evenly to the surface of the eye. Currently, the common practice is to use disposable cotton swabs to do this, that is, to use a cotton swab to pick up an appropriate amount of medication and then apply it evenly to the skin. However, this traditional method of applying medication with cotton swabs has many drawbacks.

[0003] Firstly, the fibers of the cotton swab may absorb some of the ointment; this means that the amount of eye medication actually used by the patient is reduced, the utilization rate of the medication is lowered, and the treatment effect is affected.

[0004] Secondly, the ointment is prone to leaving residue in cotton wool; this can lead to uneven application of the medication, which in turn affects the absorption and distribution of the medication in the eyes.

[0005] Thirdly, the hard handle of cotton swabs can easily aggravate skin damage during use due to excessive pressure; for sensitive and delicate areas such as the eyes, this may cause discomfort or further injury. Utility Model Content

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0033] like Figures 1 to 7 As shown, this solution provides an eye medication applicator.

[0034] Please see Figures 1 to 7 The device includes a handheld handle 1 and a brush head 2 for applying ophthalmic ...

[0035] When ordinary PP is used as the first-injection material, the injection temperature of the second-injection TPE (above 220℃) far exceeds the temperature resistance limit of ordinary PP, causing the first-injection parts to deform due to heat, and the second-injection parts cannot be completely encapsulated. Therefore, the hand handle 1 and the support 11 are made of high-temperature resistant PP material to improve the temperature resistance of the first-injection material and avoid high-temperature stamping deformation.

[0036] When TPE 30-degree material was initially selected, its low hardness resulted in sensitivity to molding conditions, such as poor flowability, easy sticking to the mold, and insufficient product support. Therefore, brush head 2 uses TPE 50-degree material to increase hardness, enhance molding stability, and improve product support.

[0037] Please see Figures 1 to 7 The brush head 2 is flat and includes an end portion 22 and a tail portion 23. The end portion 22 of the brush head 2 gradually thickens towards the tail portion 23. The end portion 22 of the brush head 2 is used for applying to the eye area, and the support member 11 is located at the tail portion 23 of the brush head 2. Preferably, the cross-section of the brush head 2 is trapezoidal, with the upper base of the trapezoid formed by the end portion 22 and the lower base of the trapezoid formed by the tail portion 23.

[0038] Please see Figures 1 to 7 Because the applicator is small and applies glue evenly, it tends to stick to the front mold during demolding, leading to demolding failure. Therefore, the edges of the brush head 2 are all rounded surfaces 21. This reduces mechanical gripping force. Moreover, the rounded surface 21 design can prevent eye scratches caused by misoperation or excessive force during application, making it especially suitable for sensitive areas around the eyes.

[0039] Please see Figures 1 to 7 The support member 11 has a trapezoidal cross-section, and grooves 13 are formed between the front and rear ends of the support member 11 and the handle 1. The grooves 13 increase the contact area between the support member 11 and the brush head 2, thereby improving the bonding strength between the two.

[0040] Please see Figures 1 to 7 The handle 1 has a bevel 12 along its length at one end near the support 11, making the handle 1 lower on the left and higher on the right. The handle 1 also has bevels 12 on both its upper and lower sides. This prevents the edge of the handle 1 from touching the eyes when applying medication.

[0041] Operating steps:

[0042] The operator holds the handle 1 of the applicator, dips the end 22 of the brush head 2 into the ointment, holds the handle 1, and makes the end 22 of the brush head 2 contact the skin of the eye to apply the medicine.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
