Description

Blunt end disposable aseptic syringe needle

Technical Field

The utility model relates to a syringe needle, especially a blunt end disposable aseptic syringe needle.

Background

Subcutaneous injection is a common drug injection mode in clinical medicine, can enable drugs to achieve blood circulation from subcutaneous tissues, can prevent the drugs from being damaged by digestive juice, mucous membranes and liver enzymes in gastrointestinal tracts before entering the blood circulation of the whole body to reduce the curative effect, and common subcutaneous injection drugs comprise insulin, vaccines, iron removers and the like. At present the disposable syringe needle of many uses during hypodermic medicine, when carrying out the hypodermic operation, because the pinhole of ordinary syringe needle is located the needle tubing end, the doctor need guarantee the complete injection with the great angle of needle tubing slope when injecting, the injection degree of difficulty is higher, to some novice doctors, appear easily because of injecting the phenomenon that the injection position skin is rugged inadequately and leads to, in addition, because the medicine majority of hypodermic is comparatively expensive medicine, current syringe needle leads to the waste of medicine easily at the connection position weeping. Therefore, a need exists in the medical device field for a hypodermic disposable needle that is easy to inject and does not waste medication.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a blunt end disposable aseptic syringe needle. The injection device has the advantages of easy operation during injection, good medicine injection effect and difficult waste of injected medicines.

The technical scheme of the utility model: a blunt end disposable aseptic syringe needle, including the needle bar, the needle bar connects with the needle tube through the joint part, the outside of the needle tube is fitted with the sheath linking with end of needle bar; the end of needle tubing is closed blunt head, and the needle tubing lateral wall at blunt head place is equipped with the pinhole, is equipped with the instruction arrow point on the needle file, instruction arrow point and pinhole are located the both sides of needle file and needle tubing common axis respectively.

In the above sterile injection needle with a blunt end for one-time use, the end of the needle holder is provided with a connecting thread.

In the sterile injection needle with the blunt end and the disposable use, the needle tube is provided with scale marks.

In the above-mentioned sterile injection needle with a blunt end and a disposable use, the port of the sheath is an elastic bayonet.

In the foregoing blunt-ended single-use sterile injection needle, the distance between the needle hole and the blunt tip end is 0.6 to 1.0 mm.

In the above-mentioned sterile injection needle with a blunt end for single use, the outer diameter of the needle tube is 0.3 to 1.2 mm.

In the above-mentioned sterile injection needle with blunt end and disposable use, the length of the needle tube is 25-120mm, and the length of the needle tube is increased or decreased by 5mm in the range of 25-120mm to be a specification.

Compared with the prior art, the utility model discloses a needle tubing end is closed blunt head, muscle tissue and blood vessel in the skin are difficult for hindering when the injection, be difficult for puncturing the blood vessel and cause the blood stasis blue or green and the swelling at injection position, its pinhole position is the lateral wall of needle tubing, the doctor can hug closely the injection position completely with the pinhole when the injection, fully carry out the medicine injection, it is effectual to inject, the whole inclination of needle tubing also need not too big, reduce the injection degree of difficulty on the whole, difficult emergence causes injection position skin unevenness or causes the vascular embolism because of the injection is insufficient, in order to make the injection easier to operate, it is more accurate, the utility model discloses be equipped with the instruction arrow point on the needle file, instruction arrow point and pinhole are located the both sides of needle file and needle tubing common axis respectively, also when the needle tubing inserts the injection, the instruction arrow point can give the doctor instruction, make the needle tubing insert the, providing basic guarantee for the full injection of the medicine; because hypodermic's medicine majority is comparatively expensive medicine, the utility model discloses a needle file end is equipped with connecting thread for syringe needle can be with supporting cylinder threaded connection, and it is inseparabler to connect, can not lead to exploding the appearance of needle phenomenon because of inside and outside pressure difference, also is difficult for producing the weeping, and is little to the waste of injection medicine.

Furthermore, the needle tube is provided with scale marks, because the hypodermic needle is generally of a long and thin structure, the length of the inserted skin is not easy to control, and the existence of the scales enables a doctor to have more objective understanding on the insertion length of the needle tube, so that the injection can be more accurate, and the injection effect is improved.

In addition, the port of sheath is the elasticity bayonet socket, changes the installation sheath during syringe needle production, changes when using and pulls down the sheath, provides convenient for the use of syringe needle.

To sum up, the utility model has the advantages of easy operation, good medicine injection effect and difficult waste of injected medicines during injection.
