Description

Technical Field

[0001] The utility model belongs to the technical field of eye cleaning, and in particular relates to a pen-type eyelid margin cleaning device. Background Art

[0002] Dry eye (DED) is one of the most common ocular surface inflammatory diseases, which can be divided into aqueous deficiency dry eye (reduced tear secretion), evaporative dry eye (excessive tear evaporation), or a mixture of the two. More than 85% of DED patients belong to the evaporative type, and meibomian gland dysfunction (MGD) is the main cause of evaporative dry eye.

[0003] Meibomian glands are located in the tarsal plate, and their openings are open to the ocular surface along the edge of the eyelid. Normally functioning meibomian glands can secrete meibomian fat to cover the surface of the tear film to stabilize the tear film, reduce evaporation, and prevent dry eyes. Meibomian gland dysfunction (MGD) is the blockage of the meibomian gland ducts and openings by abnormal meibomian fat, forming a coagulated lipid film, excessive keratinization of the meibomian gland terminal ducts, and decreased secretion of the meibomian glands, leading to dry eye symptoms.

[0004] In clinical practice, eyelid margin cleaning wipes are usually used to clean the eyelid margin, and physical therapy is performed for MGD to relieve eyelid margin inflammation and restore the discharge and secretion functions of the meibomian glands to reduce pressure in the glands and relieve dry eye symptoms.

[0005] However, 1. The opening of the meibomian gland is small, and the cleaning wipes cannot accurately clean the opening of the meibomian gland, allowing the coagulated ester membrane to open and the meibomian ester to flow out.

[0006] 2. There is a lot of liquid in the cleaning wipes. When cleaning the eyelid margin, due to the squeezing effect, the liquid may overflow over the eyelid margin into the eye, causing discomfort to the patient.

[0007] 3. Different patients have different eyelid sizes, shapes, and eyelid margin conditions, so cleansing wipes cannot be suitable for all patients. Utility Model Content

In this embodiment, the cleaning head 11 is a disposable ophthalmic triangular cotton, which is divided into different models, and can be personalized according to the eyelid size and eyelid margin shape of different patients. Suitable models can be replaced after use.

[0045] The connecting handle 12 includes a fixed end and a liquid supply pipe 121 connected to each other, and the cleaning head 11 is detachably connected to the fixed end and the connecting handle 12 through the connecting portion 112. The fixed end includes a plurality of liquid supply channels, and the ends of all the liquid supply channels close to the cleaning head 11 are in contact with the connecting portion 112, and the ends of all the liquid supply channels away from the cleaning head 11 are connected to the liquid supply pipe 121.

A rubber plug 214 is provided in the fourth through hole, and a cross seam is provided at the center of the rubber plug 214. The liquid supply tube 121 is inserted into the rubber plug 214 to connect the replacement pen head 1 with the pen body 2. At this time, the liquid supply tube 121 is connected to the liquid storage tube 211. The built-in piston 213 can move in the liquid storage tube 211, and the area between the connector 212 and the built-in piston 213 in the liquid storage tube 211 is filled with eyelid margin cleaning liquid. When the built-in piston 213 moves, the eyelid margin cleaning liquid can be injected from the liquid storage tube 211 into the liquid supply tube 121 and reach the cleaning head 11.

[0051] The liquid storage tube 211 is transparent and provided with scales, so that the remaining amount of the eyelid margin cleaning liquid in the liquid storage tube 211 can be directly seen.

[0052] The replacement refill 21 is sleeved with a pen holder 22 on the outside, the inner diameter of the head of the pen holder 22 is smaller than the outer diameter of the connector 212, the head of the pen holder 22 is provided with a fifth through hole 221, the fifth through hole 221 is coaxial with the fourth through hole, and the liquid supply tube 121 is adapted to the fifth through hole 221. The tail of the pen holder 22 is connected with an operating component 23, and the operating component 23 can apply thrust to the built-in piston 213. Specifically, the operating component 23 includes an operating rod 231 and a connecting cylinder 232, and the head of the connecting cylinder 232 is detachably connected to the tail of the pen holder 22. When in use, the replacement refill 21 is placed in the pen holder 22, and the pen holder 22 is connected to the connecting cylinder 232 to install the replacement refill 21 in the pen body 2. When the eyelid margin cleaning liquid in the replacement refill 21 is used up, the pen holder 22 and the connecting cylinder 232 are disassembled, the replacement refill 21 is taken out and replaced with a new replacement refill 21.

[0053] In addition, a visual window 222 is provided on the side wall of the pen holder 22 . When the replacement refill 21 is installed in the pen holder 22 , the scale is located at the visual window 222 , and the remaining amount of liquid in the replacement refill 21 can be viewed at any time.

[0054] The operating rod 231 includes an inner push rod 2311 and an outer rotation rod 2312 which are threadedly connected. The outer rotation rod 2312 is connected to the connecting tube 232 via a friction plug 233 which is sleeved on the outer side of the outer rotation rod 2312. The outer rotation rod 2312 is sleeved on the outer side of the inner push rod 2311. Figure 3 , Fig.10 As shown, the outer wall of the inner push rod 2311 includes a threaded portion 23111 and a flat portion 23112. The inner wall of the connecting tube 232 is provided with a limit plate 234.

[0055] When in use, first screw the outer rod 2312 outwards, at this time, because the inner push rod 2311 is limited by the limiting disk 234, the inner push rod 2311 remains motionless, and after the outer rod 2312 is screwed out of the amount of the eyelid margin cleaning solution that you want to inject, stop screwing the outer rod 2312, and press the outer rod 2312 into the connecting tube 232 until the positioning disk 2313 is stuck by the connecting tube 232. While the outer rod 2312 moves in the connecting tube 232, the inner push rod 2311 pushes the built-in piston 213, so that the eyelid margin cleaning solution in the liquid storage tube 211 is injected into the liquid supply tube 121 to reach the cleaning head 11 and soak the cleaning head 11. The method of pushing the outer rod 2312 in a certain distance after the outer rod 2312 is rotated outwards can accurately control the liquid output of the eyelid margin cleaning solution, and while wetting the cleaning head 11, too much liquid will not overflow and enter the eye surface, causing eye surface irritation.
