Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The utility model provides a precise one milliliter syringe as shown in Figures 1-3, comprising a syringe 1, a storage cavity 2, a rubber stopper 3, a push rod 4, a needle core 5, a fixing block 6, a common injection scale 7 and Insulin injection scale 8, a storage cavity 2 is opened in the syringe 1, the rubber stopper 3 is arranged in the storage cavity 2, and one end of the push rod 4 is arranged on the rubber stopper 3, located in the storage cavity 2 The other end extends out of the storage cavity 2 and is located outside the needle cylinder 1. The needle core 5 is arranged on the needle cylinder 1 and is connected to the storage cavity 2. The fixing block 6 is sleeved on the The outer side of the needle core 5 is located on the syringe 1, the fixing block 6 is integrally formed with the syringe 1, and both sides of the circumference of the syringe 1 are respectively provided with a common injection scale 7 and an insulin injection scale 8. , the outer side of the needle core 5 is detachably installed with a protective structure; the protective structure includes a fixed seat 9 and a needle tube 10, the fixed seat 9 is provided with a needle tube 10, when the needle tube 10 is sleeved on the needle core 5 When the fixed seat 9 is in contact with the fixed block 6; the inner diameter of the needle tube 10 is the same as the outer diameter of the needle core 5; when the needle tube 10 is sleeved on the needle core 5, the needle core 5 is located in the needle tube 10; the fixing block 6 is provided with a handle 11;

In specific use: the fixing seat 9 and the needle tube 10 are set on the needle core 5, the outer diameter of the needle core 5 is the same as the inner diameter of the needle tube 10, so that it can be effectively sealed, and at the same time the fixing seat 9 is in contact with the fixing block 6, and the fixing seat A sealing gasket 12 is installed between the 9 and the fixing block 6 to further prevent air leakage during use, and then the needle tube 10 is penetrated into the sealed bottle to absorb the medicinal liquid. Since the needle tube 10 is wrapped outside the needle core 5, when inserted When the bottle is sealed, the needle tube 10 is in contact with the sealed bottle cap, which effectively prevents the needle core 5 from changing during the drug absorption process, which affects its subsequent use.
