Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a stem cell factor eye drop device. Background Technology

[0002] Corneal injury in dogs and cats often leads to problems such as excessive tearing, increased eye discharge, photophobia, and difficulty in scar tissue repair. These are common issues in veterinary clinics. Untreated corneal injuries can result in scar tissue that significantly weakens a pet's vision. The secretions from in vitro cultured mesenchymal stem cells contain a large number of active ingredients, such as stem cell growth factor (SCF), fibroblast growth factor (FGF), epidermal growth factor (EGF), cell colony-stimulating factor, collagen, and more than 80 other active ingredients, which have a certain effect on promoting the recovery of corneal injuries.

[0003] In the clinical treatment of pet ophthalmology, the use of drug delivery devices is essential. During drug delivery, pets often have difficulty opening their eyes due to disease or muscle damage. Traditional drug delivery devices cannot open the pet's eyelids during the instillation process, requiring the veterinarian to manually open the pet's eyes to administer the drug. This method has certain limitations, and some medications require the pet's eyelids to be kept open for a certain period of time to prevent the medication from being squeezed out after the eyes are closed, which would reduce the therapeutic effect. This is extremely inconvenient in clinical practice. Utility Model Content

[0004] This invention provides a stem cell factor eye drop device with a reasonable structural design to solve the technical problems existing in the prior art. This invention can open the pet's eyelids during treatment and maintain this open state for a certain period of time, facilitating drug administration.

[0005] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A stem cell factor eye drop device includes a mounting arm with a longitudinally extending strip-shaped hole, a bottle mouth clamping assembly mounted on the mounting arm for clamping the bottle mouth of a container filled with eye drops, and a pressing and tightening assembly mounted on the bottle mouth clamping assembly for pressing and positioning the bottom of the inverted container; it also includes an eyelid opening assembly mounted at the lower part of the bottle mouth clamping assembly for opening the eyelids; the eyelid opening assembly includes two lead screw seats fixed to the bottle mouth clamping assembly, each lead screw seat having a horizontally arranged moving guide rod fixed to it, and two arc plate opening mechanisms slidably connected and symmetrically arranged between the two moving guide rods; it also includes an adjustment drive mechanism for adjusting the distance between the two arc plate opening mechanisms.

[0006] The advantages and positive effects of this utility model are as follows: This utility model provides a stem cell factor eye drop device. Through the set pressing and tightening component and the bottle mouth clamping component, the container filled with eye drops can be clamped and positioned. Through the set eyelid opening component, the upper and lower eyelids of the pet can be opened, eliminating the need for staff to manually open the pet's upper and lower eyelids for drug administration. The operation process is simple; only when the lower end of the arc plate opening mechanism is in contact with the upper and lower eyelids, the drive mechanism can be rotated and adjusted to drive the two arc plate opening mechanisms to slowly move in opposite directions, thereby slowly opening the pet's upper and lower eyelids, facilitating subsequent eye drop operation. By setting the mounting arm, the longitudinal position of the eye drop device can be adjusted, thus ensuring that the two arc plate opening mechanisms in the eyelid opening component are in contact with the pet's upper and lower eyelids.

A limiting block is fixedly connected to the inner end of each limiting rod. The limiting block is a wedge-shaped block. An inclined surface that matches the inclined surface of the limiting block is provided on the outer side of the limiting mounting base.

[0009] Preferably, the adjustment drive mechanism includes a drive screw rotatably connected to one of the two screw seats. The drive screw is arranged parallel to the drive screw and is a left-right turning screw. The drive screw is connected to the two arc plate opening mechanisms through a screw nut.

[0010] Preferably, the bottle neck clamping assembly includes a clamping mounting base fixedly attached to a mounting arm. A through groove is provided in the middle of the clamping mounting base.

During eye drop application, the bottle containing the eye drops can be squeezed to apply the eye drops.

[0023] like Figure 4 As shown, the eyelid opening assembly 4 includes two lead screw seats 4-2 fixed to the bottle mouth clamping assembly 3, and a horizontally arranged movable guide rod 4-4 fixed to each lead screw seat 4-2. Two arc plate opening mechanisms are slidably connected to and symmetrically arranged between the two movable guide rods 4-4. It also includes an adjustment drive mechanism for adjusting the distance between the two arc plate opening mechanisms.

[0024] The aforementioned arc plate opening mechanism includes a movable base 4-7 slidably passing between two drive screws 4-3. Several buffer springs 4-6 are installed at the bottom of the movable base 4-7 and connected to a limiting mounting seat 4-10.

[0028] Working principle:

[0029] In actual operation, the aforementioned mounting arm 1 is installed on the pet treatment table, and its longitudinal position is adjustable. Ensure that the affected eye of the pet is positioned directly below the eyelid opening assembly 4. Pull upwards the pressing and tightening plate 2-5 in the pressing and tightening assembly 2. Invert the container filled with eye drops and insert it into the through groove on the clamping mounting base 3-6. Use the paired bottle mouth clamps 3-3 to hold the bottle mouth. Then release the pull on the pressing plate 2-5. Under the action of the pressing spring 2-3, the pressing plate 2-5 presses downwards onto the bottom of the container. Under the action of the pressing and tightening assembly 2 and the bottle mouth clamping assembly 3, the eye drops can be... The container is stably clamped and positioned. Rotating the handle 4-1 causes the moving guide rod 4-4 to rotate, thereby adjusting the distance between the two opening arc plates 4-12 according to the affected eye, so that the two opening arc plates 4-12 are located at the edges of the upper and lower eyelids of the affected eye, respectively. Adjusting the mounting arm 1 downwards so that the two opening arc plates 4-12 are in contact with the pet's upper and lower eyelids, respectively. Then, rotating the handle 4-1 in the opposite direction causes the moving guide rod 4-4 to rotate in the opposite direction, causing the two opening arc plates 4-12 to move slowly in opposite directions, thereby slowly opening the pet's upper and lower eyelids. After completing the above operations, medication can be administered to the pet's eyes.
