Problems solved by technology

However, the friction between the piston and the sleeve is relatively large. In order to ensure that the piston can rebound quickly, a spring with a large elastic coefficient is generally used, that is, a relatively large pressure is required to drive the piston to slide upward, and a large pressure will cause the piston to slide upward. As a result, the eye drops flow out too fast. If the bottle mouth is replaced with a very thin needle tube, it will form a liquid column with a strong impact instead of a gently dripping drop.
That is, although the packaging bottle of Helite Sodium Hyaluronate Eye Drops can significantly extend the shelf life of the eye drops, the mouth of the bottle cannot be replaced with a very thin needle tube.
[0006] In addition, when dropping eye drops, the mouth of the bottle is generally very close to the eyes. Such a small needle tube is almost invisible to the eyes at such a short distance, so it is impossible to aim at it.
If the needle tube is made of soft plastic, it is easy to shake and cause tension; if the needle tube is made of hard plastic or metal, it is too dangerous, and almost no one dares to try it
[0007] In short, the needle-shaped drip nozzle has not been adopted by the eye drops industry due to its various defects and practical factors.

specific Embodiment 1

[0033] combine figure 1 , figure 2 and Figure 5 As shown, a self-closing needle-shaped drip nozzle is used to be fixedly connected to the mouth of the eye drop bottle, including a sleeve (2) with a closed top and an open bottom and a needle tube that runs through the top and is fixedly connected with the top (3); the bottom end of the needle tube (3) is closed by a baffle (6), and a small hole is opened on the lower side wall; it also includes a sliding sleeve (4) with two ends open and an elastic diaphragm ( 5), the inner wall of the sliding sleeve (4) is airtightly sleeved on the lower part of the needle tube (3), and its outer wall runs through the elastic diaphragm (5) and is airtightly fixed with the elastic diaphragm (5) Connection; the edge of the elastic diaphragm (5) is airtightly fixedly connected to the bottom opening of the sleeve (2).

[0034] When the bottle body (1) is squeezed, the eyedrops in the bottle will force the elastic membrane (5) to bulge upwards...

specific Embodiment 2

[0038] like image 3 As shown, an eye drop bottle includes a bottle body (1) and a bottle cap (10), and the above-mentioned self-closing needle-shaped drip nozzle is also installed; the lower part of the self-closing needle-shaped drip nozzle is connected to the The mouth of the bottle body (1) is airtightly fixedly connected, and the top of the needle tube (3) is detachably airtightly connected to the bottle cap (10); it also includes a condenser lens (8), a mirror reflector layer (7) and a connecting piece (9); the upper part of the needle tube (3) runs through the specular reflection layer (7) and the condenser lens (8) sequentially from bottom to top; the connecting piece (9) ) is fixedly connected to the edge of the condenser lens (8), and its lower part is detachably fixedly connected to the mouth of the bottle body (1); the upper end of the connecting piece (9) exceeds the needle tube ( 3) at a distance from the upper end of the needle tube (3) to completely eliminate ...

specific Embodiment 3

[0041] combine Figure 4 and Image 6 As shown, the center of the condensing lens (8) is depressed downwards to form a circular well, and the edge of the circular well exceeds the upper end of the needle tube (3) by a certain distance; it also includes a flexible plastic capsule bag (11), the capsule The opening of the bag (11) is airtightly and fixedly connected to the lower part of the self-closing needle-shaped drip nozzle; an air inlet hole is provided in the middle of the bottle body (1); when the bottle body (1) is squeezed, fingers block When the air inlet is closed, the air pressure in the bottle will rise, and then the pouch (11) will be forced to shrink; when the bottle body (1) is relaxed, the finger will loosen the air inlet, and the air pressure in the bottle will return to normal. This technical solution can also eliminate the possibility that the upper end of the needle tube (3) touches the eyes, and at the same time avoid the technical solution of the second e...

Abstract

The invention provides a self-closing needle-shaped drip nozzle and an eye drop bottle, which relate to the technical field of medical containers. The self-closing needle-shaped drip nozzle can ensure that the dripping liquid is very small, and at the same time prevent air and bacteria from contaminating the eye drops inside the bottle, thereby effectively prolonging the shelf life of the eye drops; The condensing lens and specular reflection layer can see the clear and magnified eye image at close range, so that eye drops can be instilled more easily and accurately, which perfectly solves the technical defect that the needle dropper cannot be aimed.

Description

Technical field: [0001] The invention relates to the technical field of medical containers, in particular to drip nozzles and eye drops bottles. Background technique: [0002] At present, eye drops are generally packaged in plastic bottles. The droplet dripping from the mouth of this plastic bottle is too large, exceeding the capacity of the conjunctival sac, which wastes eye drops and makes people feel swollen and uncomfortable. [0003] For this reason, publication number is that the patent of the CN2121948U proposes a kind of needle-type plastic eye drop bottle. The bottle mouth of the eyedrop drop bottle is a very thin needle tube, and the droplet dripped out is very small, in order to achieve the effect of saving eyedrops. [0004] However, the eye drops bottles sold on the market generally have a large capacity and cannot prevent air and bacteria from contaminating the eye drops inside the bottle, resulting in a short shelf life of the eye drops. When the droplet dri...
