Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a corneal oxygen blowing instrument. Background Art

[0002] Corneal edema is a common symptom of ophthalmic diseases. It refers to the increase of corneal water content leading to a variety of eye symptoms. It is one of the common signs of eye diseases in clinical practice. If not treated in time, it can seriously affect vision. If the condition is not cured, it can lead to blindness. Corneal edema is especially prone to occur after cataract phacoemulsification. Corneal oxygen insufflation is a common and effective treatment for corneal edema.

[0003] At present, there are clinically focused instruments dedicated to corneal oxygen blowing, such as the patented corneal oxygen blowing eye mask with announcement number CN202526539U, which uses a glasses-style frame and replaces the lenses with a bowl-shaped eye mask structure with an oxygen tube interface. Although this structural design is relatively simple, it is not very stable to wear. At the same time, open-type oxygen blowing can easily cause oxygen waste. At the same time, both eyes need to be connected to two oxygen delivery pipelines, and the pipeline layout is relatively troublesome.

[0004] Another example is the patent with announcement number CN208525213U - an ophthalmic corneal oxygen blowing eye mask, comprising an eye mask body, a support rod symmetrically provided on the upper side of the eye mask body and connected thereto, a connecting plate fixedly connected thereto at one end of the support rod away from the eye mask body, a slide groove provided on the upper side of the connecting plate, a slider slidably connected thereto inserted in the slide groove, a motor fixedly connected thereto provided on the inner side wall of the lower end of the connecting plate, the output end of the motor passes through the upper side wall of the connecting plate and is rotatably connected thereto, a rotating disk provided on the output shaft of the motor, and a first fixing rod fixedly connected thereto symmetrically provided on the upper side of the rotating disk. The advantage is that a control device is added to the existing corneal oxygen blowing mask, and the air bag is intermittently pushed by the control device, so that the oxygen in the air bag is blown to the human eye to treat the eye. Since the intermittent oxygen supply conforms to the habit of the human eye, it will not cause discomfort to the human eye and affect the treatment. The structure design of the eye mask is relatively complex, and the intermittent oxygen blowing is realized by a control device with a relatively complex structure, which is cumbersome to operate and has a relatively high cost.

[0005] Another example is the patent with announcement number CN215307360U - an ophthalmic corneal oxygen blowing eye mask with a control device, including a frame, an air pump and an elastic rope, the air pump is arranged above the frame, an air inlet pipe is arranged on one side of the air pump, the delivery pipe is arranged on the other side of the air pump, and air delivery branches are arranged on both sides of the end of the delivery pipe. The beneficial effect is that by setting a support, a telescopic rod, a paddle, a magnetic block 1 and a magnetic block 2, the user can adjust the position of the magnetic block 2 by paddle, through the telescopic rod and the rotation on the support, and at the same time, through the magnetism of the magnetic block 1 and the magnetic block 2, the air delivery branch is driven to move to the user's eyes, so that the exhaust hole on the air delivery branch is aligned with the user's eyeball, so that oxygen can be accurately blown to the user's cornea, improving the accuracy of oxygen delivery treatment, thereby reducing the amount of oxygen used and not causing resource waste. This technology uses a moving magnetic block to drive the air delivery branch to move to achieve precise oxygen blowing, and the structural design is relatively complex, and the cost of use is relatively high.

[0006] Based on this, it is necessary to develop an oxygen blowing equipment with simple structure, easy use and relatively low cost. Utility Model Content

Oxygen enters through the oxygen supply line 2, and is diverted into two oxygen containing grooves 11 through the flow channel 12 inside the eye mask 1. Since the oxygen containing grooves 11 are directly opposite to the patient's eyes, oxygen can be effectively blown on the patient's cornea to achieve oxygen blowing treatment for the cornea. The entire instrument uses the eye mask 1 as the main body, and an oxygen supply line 2 is connected to the supply line. The pipeline layout is relatively simple. At the same time, oxygen is diverted through the flow channel 12 and supplied to the two oxygen containing grooves 11, directly acting on the cornea of ​​the patient's eyes, effectively using oxygen for corneal oxygen blowing treatment, and less oxygen waste. The entire instrument structure is simple and reasonable in design, and is relatively convenient to use.

[0036] As a preferred embodiment, the silicone ring 14 is provided with drainage notches 141 at both ends of the eye mask 1 .

[0037] In the above embodiment, since the oxygen transported by the oxygen inlet pipeline 2 is diverted into the two oxygen containing grooves 11 through the flow channel 12 and then blown toward the corneas of both eyes of the patient, the discharge notch 141 can be provided to enable the oxygen entering the oxygen containing groove 11 to be discharged normally, thereby avoiding the occurrence of excessive air pressure in the oxygen containing groove 11.

[0038] In this embodiment, the flow channel 12 is V-shaped, the apex of the V-shaped flow channel is connected to the oxygen inlet pipeline 2, and the two ends thereof are respectively connected to the two oxygen containing grooves 11, so as to achieve good oxygen supply to both eyes, and the design is relatively reasonable.

[0039] As a preferred embodiment, a control valve is provided at the oxygen inlet 15 .

[0040] In the above embodiment, the control valve can be used to control the opening and closing state of the oxygen flow meter of the oxygen inlet 15, thereby achieving good control of the oxygen blowing to both eyes.

[0041] As a preferred embodiment, the control valve is a solenoid valve, the eye mask 1 is provided with a power supply connected to the control valve, and the control valve is connected to the controller 5 via a line.

[0042] In the above embodiment, the controller 5 can realize the opening and closing of the control valve, thereby realizing the opening and closing of the oxygen inlet 15, so that the intermittent control operation of double-eye oxygen blowing can be realized, which is very flexible to use.

[0043] As a preferred embodiment, the surface of the eye mask 1 is coated with an opaque coating, a focusing light source is embedded in the bottom wall of the oxygen containing groove 11, the focusing light source is connected to the power supply, and a switch for controlling the focusing light source to light up or extinguish is provided on the eye mask 1.

[0044] In the above embodiment, by providing a focusing light source in the oxygen containing groove 11 of the eye mask 1, the patient's eyes can be focused by the focusing light source, so that oxygen can be effectively acted on the patient's cornea after being blown into the oxygen containing groove 11.

[0045] In this embodiment, the focused light source may be a red light source in a wavelength band suitable for eye therapy.

[0046] In this embodiment, the oxygen inlet pipeline 2 is a corrugated pipe, so that the oxygen inlet pipeline 2 has a good stretching effect and deformation ability, which facilitates the connection of the pipeline.
