Abstract

The utility model belongs to an improvement for the plastic eyedrops bottle, which is composed of a plastic bottle body, a bottle neck, a bottle head and a bottle cover. The plastic eyedrops bottle is characterized in that the pore diameter of the bottle head is small, and the drop opening presents a needle-point shape. The drop dose of each eyedrop is kept between 10 microliters-20 microliters every time. The plastic eyedrops bottle has simple structure and easy manufacture; the dose of each eyedrop of the eyedrops is in an ideal range by utilizing the plastic eyedrops bottle; the eyedrops can not flow out of the eyes.

Description

Needle type plastic eyedrops bottle

This utility model belongs to a kind of improvement of medical plastic collyrium drop bottle.

Before this utility model is made, the plastics collyrium drop bottle that generally uses when people treat oculopathy, every of the collyrium that at every turn oozes drips amount between 40.8～74.8 microlitres, has surpassed the capacity of ophthalmic conjunctival sac.Collyrium often overflows outside the eye, causes discomfort to user.Because ophthalmic conjunctiva blister cavities solution increases.Stimulated tissues such as cornea and conjunctiva, reflexive causes that lacrimal secretion increases.Accelerate the current drainage of medicine, not only do not reached ideal therapeutic effect, and caused waste.At present, the ophthalmology medical worker thinks.The each every ideal scope of amount of collyrium should be between 10～20 microlitres.If with droplet minim eye and be no more than big effect of dripping amount, use original plastic dropping bottle, no matter use which kind of way, also difficulty is controlled at the amount of dripping in the ideal range.

The purpose of this utility model provides a kind of improved plastics collyrium drop bottle.The every amount of dripping is remained in the ideal range.

The purpose of this utility model is to realize like this.The aperture of original plastics collyrium drop bottle bottle head is dwindled.Become the straightforward tract of 0.3mm.Length is no less than 5mm.Its top is that the drip place is made into tip-like, with medical injection needle point sample.Diameter is about 0.5mm.Maximum gauge is no more than 1mm.The injection needle of an available joint about 10mm is connected to bottleneck.Every amount of dripping of the drop bottle of Zhi Zuoing can remain between 10～20 microlitres like this.

This utility model is because only need the aperture of original plastics collyrium drop bottle bottle head is dwindled, and drip is made tip-like.Need not increase cost and operation.So structure is simple especially.It is very easy to make; Simultaneously, use pin type collyrium drop bottle, collyrium can not overflow outside the eye, and it is comfortable that user is felt, acceptant; And, use pin type collyrium drop bottle.The amount of dripping does not surpass the capacity of ophthalmic conjunctival sac.Collyrium splashes into the discharge of ophthalmic and slows down, and has improved the medicine effective concentration retention time.Strengthened therapeutic effect; In addition.Because medicament for the eyes water droplet amount reduces.Save the collyrium consumption, reduced waste.

Concrete structure of the present utility model is drawn by following examples and common accompanying drawing.

Fig. 1 is the audio-visual picture according to the pin type plastics collyrium drop bottle that the utility model proposes.

Fig. 2 is according to the structural map that removes the pin type plastics collyrium drop bottle behind the bottle cap that the utility model proposes.

Describe in detail according to concrete structure and the manufacture method that the utility model proposes below in conjunction with Fig. 1, Fig. 2.

This utility model becomes ampuliform by plastic production.Form by body (1), bottleneck (2), bottle head (3) and bottle cap (4).

During making, body (1), bottleneck (2) and bottle cap (4) are with original medical plastic collyrium drop bottle.Just change original plastics eyedrops bottle head.When making pin type plastics collyrium medicine bottle.Bottle head (3) is thinner.Diameter is about about 0.5mm, and maximum must not surpass 1mm, length is 10mm.The shortest 5mm that is not less than; Bottle head (3) internal orifice dimension is 0.3mm.The top (drip place) of bottle head (3) is made into oblique needle point.Bottle head (3) available plastic production, medical No. 5 injection needles that are not more than of the above-mentioned bottle of also available joint head length degree are connected to bottleneck (2).Fixed on every side, with anti-slip.So promptly can be made into pin type plastics collyrium drop bottle.

Claims

1, pin type plastics collyrium drop bottle is made up of plastics body (1), bottleneck (2), bottle head (3), bottle cap (4).This utility model is characterised in that bottle head (3) aperture is little, and drip place (5) are tip-like, and the water droplet amount of whenever putting drops in one's eyes remains between 10～20 microlitres.

2, according to the described structure of right (1).It is characterized in that bottle head (3) aperture is generally 0.3mm.Length is more than the 5mm.
