Description

The invention relates to medicine, namely to ophthalmology, and is intended for chemobarotherapy of the eyes.

The purpose of the invention is to increase the effectiveness of treatment.

In FIG. 1 schematically depicts an ophthalmic pressure chamber for treating one eye; in FIG. 2 is an embodiment of a treatment chamber for treating two eyes.

The pressure chamber consists of an elastic working chamber 1 with a porthole 2 and a belt 3, an inlet 4 and an outlet 5 pipelines, a pressure gauge 6, a reservoir 7 with a drug, a nebulizer 8, an inlet pipe of a drug 9, an adjustable overpressure valve 10, an electric compressor and a receiver (not shown in FIG. 1).

The elastic chamber 1 can be made in the form of a rubber or polymer seal, tightly pressed by the strap 3 to the face. The wall thickness of the working chamber is 0.5-2.0 mm. The porthole can be made of any transparent material, for example, polymethyl methacrylate. glass.

The optimal shape of the shutter was selected using an anthropometric study with computer graphics.

Barotherapy is carried out as follows.

With a consequence of penetrating wounds, an obturator 1 pressure chamber is placed on the visual organ and tightly pressed to the face with a rubber strap 3.

Part of the air is pumped out of the chamber 1 by means of a compressor through the outlet pipe 5 and oxygen, or, if necessary, another gas, is introduced into the pipe 4, while maintaining its pressure during the therapeutic action by a constant pressure valve 10 and a pressure gauge 6. Then from of the reservoir 7, the drug substance is supplied to the nebulizer 8, where it is emulsified by ultrasound. After that, the drug substance is injected directly into the chamber via pipeline 9. After some time, the treatment gas in the chamber is replaced by a new one,

As medicinal substances, a 0.5% solution of levomycetin is used

 The camera shown in FIG. 2 is for treating both eyes simultaneously. Using the two chambers shown in Fig. 1, it is possible to separately treat the right and left eyes and simultaneously monitor their condition.

PRI me R 1. Patient A., born in 1947, was on an outpatient basis with a diagnosis of OD (right eye) - non-penetrating wound of the cornea - from 5.6.90 to 10.6.90. According to the patient, on the road from the dacha 4.6.90 he stumbled with his right eye on a branch. He went to the doctor the next day with complaints of redness of the eye, foreign body sensation in the eye, fogging. Admission status: VIS, 5 n / a, VIS OS-1., 0. OD

- pericorneal injection. In the lower part of the cornea at 17 o’clock. there is an eroded area in the center of which there is a non-penetrating wound 0.3 cm in size. The anterior chamber is of medium depth, a moisture cleaner. The lens and vitreous are transparent. The fundus without pathology. OS

- healthy. Radiographically no foreign body is observed in the eye. The patient was prescribed disensitizing (levomycetin) and vitamin investments. A course of hyperbaric oxygen therapy N; 6 using a micro-chamber at an oxygen pressure of 1.5 atm for 20 minutes After completion of treatment, VIS, 0, VIS, 0. On the cornea at 17 o'clock slight slight opacification. Deep lying environments and fundus - without pathology.

PRI me R 2. Patient K. .. 1962, p., Was on an outpatient basis at the Institute of Eye Diseases from 10/19/90 to 10/24/90 with a diagnosis of OD - a deep non-penetrating wound of the cornea. Foreign body in the conjunctiva. According to the patient. 10/18/90, while playing tennis with a racket, he broke points. A piece of eyeglass fell into the right eye. I went to the doctor the same day. Disinfectant drops are prescribed. 10.19.90 appealed to the Institute with complaints

on the feeling of a foreign body in the right eye. Admission status: VIS, 3 С-2,0 Д-0.7, VIS ОС “0,3 С-2.0 Д-1.0. OD is moderately annoyed. On the conjunctiva in the external

at the 9th hour, 3 mm from the limb, a glass foreign body 0.2x0.3 mm in size is located in the part of the ocular block. Foreign body removed with tweezers. On the 9th hour of the cornea, there is a linear non-penetrating 0.3 cm corneal wound that captures the deep layers of the stroma. The anterior chamber is of medium depth, the moisture is clean. There are no pathological changes in the fundus. OS is healthy. The patient was prescribed a course of hyperbaric oxygen therapy using an ophthalmic pressure chamber. The oxygen pressure in the chamber was 1.5 atm. Conducted 5 sessions of 20 minutes. As a medicinal substance in a pressure chamber

a mixture of a solution of levomycetin with vitamin drops was introduced, emulsified with an ultrasonic nebulizer. After 5 sessions, the corneal wound was completely epithelized. At discharge VIS, 3 С-2,0

, 0. VIS, 3 C-2.0, 0.

Thus, the use of a pressure chamber for chemo-barotherapy of the eyes allows a significant increase in the therapeutic effect in the field of barotherapy of the organ of vision and broader indications for use in the treatment of subsequent penetrating wounds and burns of the eyes.
