In conclusion, the invention has the following beneficial effects:

1. through the mutual replacement between the cleaning part 3 and the dropping liquid part 4, the two independent processes of cleaning and wiping the secretion or the liquid medicine in the eyes and dropping liquid before and after dropping liquid are closely linked, so that the device has more integrity;

2. by means of the replaceable dropper head 463, medical staff do not need to deliberately prevent infection caused by the fact that the dropper head 463 is too close to eyelashes or eyelids, the dripping distance can be properly shortened, and the dripping effect is better;

3. the lacrimal sac squeezing part 5 applies stable pressure to the lacrimal sac, so that toxic medicines can be prevented from being absorbed by human body through the lacrimal sac, and poisoning can be further prevented;

4. the dropper 46 is clamped by the dropper base 44 and the pressing rod 45, liquid medicine can be instilled by squeezing the air bag 462, the pressing rod 45 abutting on the dropper 46 in a loosening or screwing mode can flexibly adjust the height of the dropper 46, the operation is simpler, and the possibility of liquid medicine waste caused by hand shaking errors is greatly reduced.

Example 2

The difference from the embodiment 1 is that the outer side of the glass tube 461 is coated with an anti-slip layer, and the preparation method of the anti-slip layer is as follows:

taking the following raw materials in parts by weight for standby: 28 parts of water-based acrylate emulsion, 18 parts of water, 11 parts of acrylic polyurethane resin, 1 part of nano silicon dioxide, 37 parts of thermoplastic polyurethane elastomer powder, 2 parts of triethanolamine, 5 parts of maleic resin, 9 parts of silicone-acrylate emulsion and 7 parts of quartz powder.

S1, pre-prepared organic solvent: mixing the water-based acrylate emulsion, acrylic polyurethane resin, maleic resin, water, triethanolamine and silicone-acrylate emulsion, heating to 65 ℃, uniformly stirring, and keeping the temperature for 2 hours;

s2, preparing the anti-skid paint: sequentially adding nano silicon dioxide, quartz powder and thermoplastic polyurethane elastomer powder into the organic solvent in S1, uniformly stirring, heating to 70 ℃, and then preserving heat for 1 h;

s3, processing: carrying out ultrasonic treatment on the anti-skid coating obtained in the step S2 for 0.5h, then cooling to 45 ℃, stirring at a rotating speed of 1050r/min for 0.5h, and then cooling to room temperature;

s4, coating: uniformly coating the anti-slip coating obtained in the step S3 on the outer wall of the glass tube 461 by using a brush;

s5, drying: the glass tube 461 obtained in step S4 was placed in a cool and ventilated place and dried for 5 hours.

In this embodiment, because the glass tube 461 is pushed against the inner wall of the dropper groove 48 by the pressing rod 45, the fixation is realized, but excessive pressing may cause the tube wall of the glass tube 461 to break, and correspondingly, if the pressing is not in place, the glass tube 461 will also slip to stab the eyeball of the patient, so that an anti-slip layer is coated on the outer side wall of the glass tube 461, which can effectively increase the friction force between the glass tube 461 and the pressing rod 45 and the dropper groove 48, and then the pressure of the pressing rod 45 against the outer side wall of the glass tube 461 can be properly reduced, thereby reducing the possibility of the tube wall of the glass tube 461 breaking, and also reducing the occurrence of the condition that the eyeball of the patient is stabbed by the glass tube 461, prolonging the service life of the glass tube 461 on the premise of avoiding major medical accidents, and meeting the environmental protection concept.

Example 3

The difference from the embodiment 2 is that the formula proportion of the anti-skid layer is modified, and the modified preparation method comprises the following steps:

taking the following raw materials in parts by weight for standby: 35 parts of water-based acrylate emulsion, 25 parts of water, 12 parts of acrylic polyurethane resin, 4 parts of nano silicon dioxide, 44 parts of thermoplastic polyurethane elastomer powder, 4 parts of triethanolamine, 8 parts of maleic resin, 13 parts of silicone-acrylate emulsion and 8 parts of quartz powder.

In this example, only the specific gravity of the formulation is modified for comparison to obtain the optimal formulation.

Example 4

taking the following raw materials in parts by weight for standby: 31.5 parts of water-based acrylate emulsion, 21.5 parts of water, 11.5 parts of acrylic polyurethane resin, 2.5 parts of nano silicon dioxide, 40.5 parts of thermoplastic polyurethane elastomer powder, 3 parts of triethanolamine, 6.5 parts of maleic resin, 11 parts of silicone-acrylic emulsion and 7.5 parts of quartz powder.

The test of the grip strength and peel strength was conducted by comparing the glass tubes 461 obtained in examples 1, 2, 3 and 4, the pull test after clamping was conducted by screwing a threaded tab button into the end of the glass tube 461, the rough grip strength was estimated by comparing the force and time of pulling off, the peel strength of the grip layer was tested by wiping, and the obtained data were normalized based on example 1, as shown in table 1

	Strength of skid resistance	Peel strength
			Example 1	100%	100%
Example 2	186%	157%
			Example 3	189%	155%
Example 4	192%	158%

TABLE 1

Because the glass tube 461 is pressed against the inner wall of the dropper groove 48 by the pressing rod 45 to be fixed, but excessive extrusion may cause the tube wall of the glass tube 461 to be broken, and correspondingly, if the extrusion is not in place, the glass tube 461 will slip to stab the eyeball of the patient, so that the outer side wall of the glass tube 461 is coated with an anti-slip layer, the friction force between the glass tube 461 and the pressing rod 45 as well as the dropper groove 48 can be effectively increased, the pressure of the pressing rod 45 against the outer side wall of the glass tube 461 can be properly reduced, the possibility of the tube wall of the glass tube 461 to be broken is reduced, the condition that the eyeball of the patient is stabbed by the glass tube 461 slipping is also reduced, the service life of the glass tube 461 is prolonged on the premise of avoiding major medical accidents, and the environment-friendly concept is met; as can be seen from the data in the table, the slip strength and peel strength of the glass tube 461 are significantly enhanced after the anti-slip layer is applied, with obvious improvement advantages, wherein the overall situation of example 4 is the best, so the best formulation is: 31.5 parts of water-based acrylate emulsion, 21.5 parts of water, 11.5 parts of acrylic polyurethane resin, 2.5 parts of nano silicon dioxide, 40.5 parts of thermoplastic polyurethane elastomer powder, 3 parts of triethanolamine, 6.5 parts of maleic resin, 11 parts of silicone-acrylic emulsion and 7.5 parts of quartz powder.
