When the diameters of silica gel particles added into the ice layer 9 are respectively 1mm, 2mm, 3mm and 4mm, and the optimal ratio of the water mass to the silica gel particle mass is 2:1, the ice compress device is compared with the traditional pure water device as follows:
| group of | n/times | t/hour | Cold compress 10 hours VAS | Cold compress for 20 hours VAS |
| Pure water | 20 | 15±2 | 4.6±1.3 | 2.5±2.3 |
| 1mm | 20 | 21±3 | 3.9±1.2 | 2.1±1.5 |
| 2mm | 20 | 29±4 | 3.7±1.9 | 1.6±1.7 |
| 3mm | 20 | 25±3 | 4.0±1.8 | 2.2±1.5 |
| 4mm | 20 | 23±3 | 4.1±2.0 | 2.3±1.8 |
In the above table, the groups indicate the size of the silica gel particles used in mm; n represents the number of experiments; t represents the time for complete thawing in hours; VAS indicates the degree of pain, (and also the degree of swelling).
According to the data, when the diameter of the silica gel particles is 2mm, the melting time is longest, and the effect of treating swelling and pain is best.
The working principle is as follows: when the eye patch is used in detail, the eye patch is worn on an affected part of eyes through the elastic bandage 2, the heat preservation layer 5 is attached to the affected part, the cavity 4 of the eye contour is placed at the eyeball, and the eyeball is placed in a frostbite mode; an inflation pump is externally connected with the air pipe connector 14, so that the expansion pipe 13 is expanded, the extruded ice layer 9 acts on the heat insulation layer 5, and the heat insulation layer 5 is completely attached to the affected part; the melted ice water flows into the flow guide layer 7 through the holes of the interlayer 8, flows into the water bag 10 through the flow guide groove 11 and the one-way water flowing port 12, and after the ice cubes are completely melted, the water in the water bag 10 flows into the ice layer 9 through the one-way water flowing port 12, so that the water is recycled, the resource waste is reduced, and the use cost is saved; the waterproof layer 6 is arranged to prevent the melted ice water from flowing out and entering eyes to cause discomfort, so that the use safety is improved, and the eye-washing ice water is more sanitary; through adding the silica gel granule at frozen layer 9, slow down the heat transfer, make ice-cube melt slower, and effectively prolong the ice-cube and melt the time, increase the pliability of ice-cube, reduce the stimulation to the affected part, guarantee the cool time and increase effective area of contact, improve the recovery effect.
The device obtained by the technical scheme is an ophthalmologic ice compress detumescence device, and due to the arrangement of a multilayer structure, the use safety is improved, and frostbite is effectively prevented; meanwhile, the arranged expansion pipe 13 is communicated with an air pump, and the device can be completely attached to an affected part during ice compress by the expansion of the expansion pipe 13, so that the swelling and pain relieving effects are enhanced; silica gel particles are added in the freezing layer 9, so that the ice block has flexibility, the melting time of the ice block is prolonged, and the treatment effect is better.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention; any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
