Abstract

The utility model relates to a disposable safety drug-dissolving syringe needle, which belongs to medical equipment. It includes a needle base, a needle stem fixed on the needle base and a needle cover set on the needle base. The hub is long and has a raised pin on the front side. A safety sheath is also sleeved on the needle seat, and an L-shaped groove is provided on the safety sheath. The convex sheath on the needle seat is inserted into the L-shaped groove of the safety sheath, and the safety sheath is located in the needle sleeve. The needle base is 25 mm long, the safety sheath is 25 mm long, and the needle barrel is 15 mm long. By using the invention, the nurse can not only ensure accurate positioning when inserting the needle, but also can reliably protect the needle after use to avoid wounding and infection. The operation is very convenient and the use is very safe. It can be widely used in the dissolution and mixing of various drugs or solvents.

Description

Disposable safe dissolving syringe needles

technical field

The invention belongs to the technical field of medical equipment, and more specifically relates to the design innovation of a disposable safe drug-dissolving syringe needle.

Background technique

Disposable drug dissolving syringes are used to draw or inject drugs or solvents in drug bottles to dissolve and mix required drugs. The needle head includes a needle base, a needle stem fixed on the needle base and a needle cover set on the needle base. The length of the needle seat of the traditional drug-dissolving syringe is 20mm, and the length of the needle barrel is 30mm. When in use, the nurse's right index finger fixes the needle holder (it is strictly forbidden to touch the needle stem to avoid contamination), insert the needle stem into the medicine bottle and suck the medicine. Because the position of the medicine bottle is upside down or tilted when the medicine is drawn, there is no need for an excessively long needle barrel. The needles of the used drug-dissolving syringes are likely to cause the danger of being stabbed by the needles during the disassembly process; when they are disposed of as medical waste, they are very easy to hurt people and even cause infection because they are not protected.

Contents of the invention

The object of the present invention is to overcome the above-mentioned shortcomings and deficiencies, and to provide a disposable safe drug-dissolving syringe needle. When in use, the nurse can ensure the accurate positioning of the needle; after use, it can reliably protect the needle to avoid injury and infection. The operation is very convenient and the use is very safe.

In order to achieve the above object, the present invention includes a needle base, a needle barrel fixed on the needle base and a needle cover sleeved on the needle base. The hub is long and has a raised pin on the front side. The outer cover of the needle hub is covered with a safety sheath with an L-shaped groove on the safety sheath. The convex sheath on the needle seat is inserted into the L-shaped groove of the safety sheath, and the safety sheath is located in the needle sleeve.

The needle base is 25 mm long, the safety sheath is 25 mm long, and the needle barrel is 15 mm long. This length is just enough to meet the needs of injecting medicine and protecting the needle, and the effect is the best.

When in use, the nurse first removes the sterile protective needle cover and throws it away, and then inserts the needle stem into the medicine bottle. After use, the nurse only needs to push the safety sheath forward, and then rotate it slightly downward along the L-shaped groove to protect the needle stem with the safety sheath, and the used needle does not need to be disassembled. Needle-stick injuries and infections are reliably avoided. Moreover, the extended needle seat can not only increase the stability of operation, but also reduce the chance of polluting the needle barrel.

Task of the present invention is accomplished like this.

By using the invention, the nurse can not only ensure accurate positioning when inserting the needle, but also can reliably protect the needle after use to avoid wounding and infection. The operation is very convenient and the use is very safe. It can be widely used in the dissolution and mixing of various drugs or solvents.

Detailed ways

Example 1. A disposable safe drug-dissolving syringe needle, as shown in Figure 1-Figure 2. It includes a needle base 1, a needle barrel 2 fixed on the needle base 1 and a needle sheath 3 set on the needle base 1. The needle holder 1 is relatively long and has a protruding pin 4 on its front side. A safety sheath 5 is also sleeved on the needle hub 1, and an L-shaped groove 6 is provided on the safety sheath. The convex sheath 4 on the needle hub 1 is inserted into the L-shaped groove 6 of the safety sheath 5 , and the safety sheath 5 is located in the needle cover 3 .

The needle base 1 is 25 mm long, the safety sheath 5 is 25 mm long, and the needle stem 2 is 15 mm long. This length is just enough to meet the needs of injecting medicine and protecting the needle, and the effect is the best.

When in use, the nurse first removes the sterile protected needle cover 3 and throws it away, and then inserts the needle stem 2 into the medicine bottle. Now because the safety sheath 5 is set on the needle base 1, the depth of needle insertion is limited and positioned, which ensures the accuracy of needle insertion, so that the medicine in the medicine bottle can just be extracted cleanly. The operation is very convenient. After use, the nurse only needs to push the safety sheath 5 forward, and then rotate it slightly downwards to protect the needle stem 2 with the safety sheath 5, which can reliably avoid wounding and infection.

Using this embodiment, the nurse can not only ensure accurate positioning when inserting the needle, but also reliably protect the needle after use to avoid injury and infection. The operation is very convenient and the use is very safe. It can be widely used in the dissolution and mixing of various drugs or solvents.
