Description

The utility model relates to medicine, namely to ophthalmology and can be used when instilling a drug into the eyes.

In ophthalmology, the most common type of treatment is eye drops, they must be used for a long time after surgical treatment, as well as in chronic diseases. The main category of patients with eye diseases is elderly people who find it difficult to use ophthalmic drugs on their own (low vision, tremor of the extremities, joint stiffness, forgetfulness). However, the effectiveness of the treatment is due to the timely effective installation of drugs.

A device is known [patent RU No. 2393823, 2010], made in the form of an eye slit with a length of 2-3 cm, a width of 1.5-2 cm, a height of 1 cm around the perimeter of the device, and the lower part along the radius of the outer side has projections of length 3 mm bent outwards. The proposed model allows you to fix the upper and lower eyelids. The device is made of soft latex material. The disadvantages are the difficulty in independent operation, possible injury.

A device for dispensing drugs [patent RU No. 2479321, 04/20/2013], consisting of a cylindrical body and a piston. The casing is made with open ends, in the casing, starting from one of the ends, a hole is made on the same side of the casing, and, at a distance of one third from the beginning of this end, a rectangular tooth with a length of 2 to 3 mm is installed, while its longitudinal axis symmetry is perpendicular to the continuation of the longitudinal axis of the hole and the generatrix of the housing, and a cylindrical cartridge with substance is tightly inserted into the housing, starting from its open end with a hole to the tooth, while one end of the cartridge is closed, equipped with an outlet cannula, the other end covered with tear-off protective film. The disadvantages of the device is the complexity of manufacturing, does not take into account the shape of the palpebral fissure, difficulty of operation.

The prototype of the utility model is a device for injecting eye drops Xalatan and Xalac - Xal-Ez Dispenser (Xal-Ease), containing a dispenser, in which a bottle of eye drops is placed, on the front surface of the dispenser there is a dispensing button, one press of which ensures the release of one drop of medicine . The device (Registration certificate: No. FSZ 2009/04638, registration date: 07/01/2009) facilitates the process of independent (without assistance) instillation of eye drops and allows you to control the dose of the drug administered. Ksal-Iz Dispenser fixes bottles of eye drops Xalatan and Xalac. The device helps to conveniently hold the bottle and inject a solution of eye drops. The kit also includes a device for opening bottles. The device for opening the bottle allows you to remove the cap after the bottle is placed in the device Ksal-Iz dispenser. This device is used as follows: the patient, before instilling medicinal solutions into the eye, first tilts his head back and pulls the lower eyelid, then draws the device closer to the eye so that the edge of the device touches the palpebral fissure, presses the dispenser button until drops from the dispenser reach into the palpebral fissure [http://organum-visus.com/xal-ease-pfizer]. However, the device has the following disadvantages: only Xalatan and Xalac eye drops are intended, it does not fix the palpebral fissure during instillation, which reduces the effectiveness of treatment, difficulty in use, and forgetfulness of elderly people is not taken into account.

The objective of the utility model is to create a universal device for comfortable instillation of liquid medicinal solutions into the conjunctiva of the eye with a reminder for the patient.

The technical result when using the utility model is to prevent the patient from blinking and the drug from flowing out of the eye, expanding the technical capabilities of the device due to the possibility of using bubbles of different sizes, and also to mark the days of the week and the frequency of instillation when used in older people.

The specified technical result is achieved by the fact that the device for instilling drugs into the eye, containing a container in which a bottle with medicinal drops is placed, and a dispensing button is located on the front surface of the container, according to a utility model, the container consists of a detachable lower part of a cylindrical shape, and an upper the part, which is made in the form of a palpebral fissure and has a protrusion bent outward, and on the back surface of the container there are three scales, the first scale showing the days of the week, the rest two scales - the frequency of instillation. Moreover, the upper part of the container is made 30 mm long, 20 mm wide, 15 mm high, and the protrusion length is 4 mm.

The essence of the utility model is illustrated by a figure, which schematically depicts the proposed device, a front and rear view.

The proposed device contains a cylindrical-shaped container in which a bottle of eye drops is placed, the container consisting of two parts, the upper part 1 is made in the form of an eye slit 3 cm long, 2 cm wide, 1.5 cm high, has a protrusion 2 4 mm long, bent outwards, used to fix the lower eyelid during instillation. The lower part 3 of the container is made in the form of a cylinder to accommodate a bottle 4 for eye drops. A button 5 is located on the front surface of the container, which serves as a dispenser (1 press 1 time = 1 drop of medicine), 3 scales are located on the back surface of the container: the first scale 6 shows the days of the week, the remaining two scales 7-8 - the frequency of instillation (figure) .

This device is used as follows: a patient pepper by instillation of medicinal solutions in the eye first tilts his head back to a vertical position, then opens the eye, then brings the device closer to the eye so that the edge of the device touches the palpebral fissure, so the device itself will fix the fissure in the open form. The patient presses the dispenser button 1 time and waits a few seconds (up to 30 seconds), then the device can be removed. After the procedure, the patient looks at the scale and puts a mark, so the patient will not forget how many times he has already dripped into the eye during the day. In this case, it is possible to use several types of eye drops.

Clinical example. Patient L., 65 years old, re-applied to the clinic with complaints of a feeling of itching and fear of light, redness of the eye.

According to the patient, he regularly instilled a medication prescribed by a doctor in his eyes, but there was no improvement. The patient associates all this with the ineffective use of drugs, due to the difficulty of self-use. After examination by a doctor, it was recommended to use the proposed device for instillation of drugs. After using the device for instillation, prescribed by the course for 10 days, a complete cure was noted, there were no complications from its use.

The proposed device was used in the II-th surgical department of the Ufa Scientific Research Institute of Eye Diseases in 15 patients. All patients with the instillation of drugs were satisfied with a simple and comfortable use of the proposed device.
