Description

The doser of eyeball sclera deep layer

Technical field:

This utility model relates to a kind of utensil of clinical ophthalmology administration, is specifically related to the doser of eyeball sclera deep layer.

Background technology:

The ophthalmic remedy nursing is the important step of patient in therapeutic process, is determining ophthalmology wholistic therapy effect of nursing.The treatment ophthalmic disease needs long-time frequent drug administration, and especially for some retinopathys, local injection meeting of long duration brings a lot of complication, and in addition, some slow releasing pharmaceuticals are directly inserted ophthalmic or vitreous chamber injection, all have pair in various degree to damage to eyeball.At present, also do not have a kind of comparatively ideal neither entering in the eyeball, can make medicine in vitreous chamber, reach the doser of the eyeball deep layer of active drug concentration again at ophthalmic disease.

The utility model content:

For solving the problem of the doser that does not also have comparatively ideal eyeball deep layer, this utility model provides a kind of doser of eyeball sclera deep layer.It comprises release dish 1, gives batch pan 2 and connection tube 3, the edge of the medicine outlet 3-2 of the right-hand member of release dish 1 and connection tube 3 is connected as a single entity, form for batch pan 2 by upper epidermis 2-1 and following top layer 2-2, the edge of upper epidermis 2-1 and following top layer 2-2 is connected as a single entity to make and forms cavity 2-3 between upper epidermis 2-1 and the following top layer 2-2, following top layer 2-2 is provided with medicine outlet 2-2-1, the feeding opening 3-1 of connection tube 3 and the medicine outlet 2-2-1 that gives batch pan 2 are connected by sealing, and connection tube 3 is communicated with cavity 2-3.This utility model in use, eyeball is cut to sclera deep layer 2/3-3/4 thickness place, and release dish 1 inserted, place under the fascia bulbi capsule for batch pan 2, medicinal liquid flows into release dish 1 through connection tube 3, and flows out through release dish 1, and medicine directly reaches Deep Layer of Sclera, be penetrated into ophthalmic through very thin scleral tissue, thereby realize the administration of sclera deep layer.This utility model volume is little, stimulates little to the eye conjunctiva; Release dish 1 does not enter vitreous chamber, does not penetrate the wall of eyeball holostrome, and wound is little, can avoid the generation of a lot of complication such as venation is hemorrhage, retina shedding, infection; The local injection that can be used for slow release tablet or other depot drug product.
