A nursing teaching model of cutting eyelashes and lacrimal duct flushing technology in ophthalmology department

Abstract

The invention relates to the field of medicines, and in particular relates to an eyelash cutting and lacrimal passage irrigation technique nursing teaching model in ophthalmology. The model comprises a head model internally provided with a cavity, wherein a face model for simulating a human face is arranged on a surface A of the head model; two left and right eye models and a nose model are arranged on the face model; the upper orbits and lower orbits of the eye models are respectively provided with shallow grooves into which upper eyelash and lower eyelash are embedded; dacryon holes are arranged at the eye corners of the eye models; the cavity of the head model is internally provided with a liquid discharge mechanism connected with the dacryon holes. The eyelash cutting and lacrimal passage irrigation technique nursing teaching model is provided for teachers and students in professional nursing schools in ophthalmology teaching, not only can the knowledge be explained referring to the model, but also exemplary operation can be made for multiple times on the model, so that the risk that danger can be caused when the exemplary operation is performed on a student is reduced, and unsafe factors are avoided; the students can repeatedly operate on the model.

Description

technical field [0001] The invention relates to the medical field, in particular to an eyelash cutting and lacrimal duct flushing technology nursing teaching model in ophthalmology. Background technique [0002] Eyelash cutting and tear duct irrigation are common ophthalmic care operations. Eyelash cutting refers to the use of ophthalmic scissors to cut the eyelashes of the upper and lower eyelids in preparation for the treatment of certain eye diseases and eye surgery. Possible complications of cutting eyelashes include: accidental eyelid injury, bleeding, etc. [0003] Lacrimal irrigation is the method of infusing a solution from the punctum into the lacrimal duct with a blunt round needle. It is suitable for cleaning the dirt in the lacrimal duct before intraocular surgery; assisting in the diagnosis of lacrimal duct stenosis and blockage in patients with epiphora, or judging the location of blockage; for patients with chronic dacryocystitis with severe corneal ulcers o...

AI Technical Summary

Problems solved by technology

[0005] 1. When teachers demonstrate and students operate with each other, there are potential unsafe factors in human experiments; 2. There are very few operation opportunities, and it is almost impossible to achieve the teaching goal of skilled operation;

[0006] 3. Students cannot intuitively understand the anatomical shape of the patient's lacrimal duct, and cannot grasp the needle insertion technique when flushing the lacrimal duct;

[0007] 4. After students enter the clinical practice, they can only operate directly on the patient's body, which increases the pain of the patient and increases the risk of complications such as cutting eyelashes and lacrimal duct irrigation;

[0008] 5. In order to alleviate the pain of patients, improve work efficiency, and reduce disputes between doctors and patients, some clinical teachers are unwilling to let students perform these two operations too much, resulting in students not receiving proper training during practice;

[0009] 6. There are few cases of lacrimal duct abnormalities that students can see in the ward, and it is difficult for students to understand the lacrimal duct obstruction, common lacrimal duct obstruction, nasolacrimal duct stenosis, dacryocystitis, etc. Abnormal manifestations of tract flushing
