Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices and relates to a syringe, in particular to a light-proof syringe. Background Art

[0002] A syringe is a common medical device used to inject medication or withdraw liquids. It consists of a barrel with a small hole at the front and a matching piston rod. The barrel can be made of plastic or glass and typically has a graduated scale indicating the volume of liquid in the syringe. The piston rod is used to move up and down within the barrel to draw in or expel liquid.

[0003] Syringes need to be protected from light in certain circumstances. This is mainly because some drugs are sensitive to light. Light may trigger chemical reactions in the drugs, causing them to become ineffective or even produce toxic substances, thereby affecting the efficacy and safety of the drugs.

[0004] Conventional light-proof syringes are usually equipped with opaque syringes to prevent the internal medicine from being exposed to sunlight and causing drug deterioration. However, the production cost of a completely opaque syringe is high and it is not easy to observe the dosage. Utility Model Content

[0005] The purpose of the utility model is to provide a combined light-shielding protection syringe to address the above-mentioned problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a light-proof protection syringe, characterized in that it includes a syringe body consisting of a syringe and a core rod, the end of the syringe is provided with symmetrically arranged fixed ears, the syringe body is provided with a light-shielding shell, the top of the light-shielding shell is provided with a rotating clip for clamping the fixed ear, a guide ring is provided between the rotating clips, the light-shielding shell is provided with a measuring scale, and the light-shielding shell is also provided with a pointing ring, the pointing ring is provided with a plurality of guide strips, and the guide strips are provided in the guide ring, and the top of the guide strip is in conflict with the top of the core rod.

[0007] In the above-mentioned light-shielding protection syringe, a needle mounting portion is provided at the bottom of the syringe, a covering portion wrapping the needle mounting portion is provided on the light-shielding shell, and a snap-in cavity is provided at the end of the covering portion, a silicone funnel is provided on the snap-in cavity, and a snap-in block is provided on the silicone funnel.

[0008] In the above-mentioned light-shielding syringe, the light-shielding shell is further provided with an ear-hanging extension portion.

[0009] Compared with the existing technology, this light-proof protection syringe prevents the liquid medicine inside the syringe from contacting the light source by setting a light-proof shell. The syringe main body adopts a conventional syringe to reduce preparation costs. The silicone funnel can further block the light source. The measuring scale on the light-proof shell and the pointing ring can intuitively inform the user of the amount of medicine used. BRIEF DESCRIPTION OF THE DRAWINGS
