Background
The skin test is short for skin sensitivity test and is a common clinical specific examination. Certain drugs are susceptible to allergic reactions during clinical use, such as: penicillin, streptomycin, cytochrome C, and the like; if a patient allergic to the medicine is directly injected with a large dose of the medicine, dermatitis, fever, asthma, anaphylactic shock and even death are easily caused. Therefore, a skin test is required to test whether it is allergic to the drug, preferably.
The formulation of the skin test agents requires strict control of the concentration of the agents, as well as the amount of the agents injected. Therefore, the conventional proposal has the following problems when preparing the skin test solution: 1. 3 skin test needles are needed for operation, a large number of instruments are used, waste is caused, and the medicament is easily polluted in the repeated configuration process; 2. the volume of the skin test needle for sucking the medicament is small, the liquid fluidity inside the skin test needle is poor, and the medicament and the solvent are difficult to be fully mixed; 3. the configuration precision is low, and the steps are complicated.

The invention aims to overcome the problems and provides a quick dispensing skin test needle. In order to achieve the purpose, the invention adopts the following technical scheme:
a skin test needle for rapid dispensing comprises a needle head, an injector cylinder and a piston, wherein the injector cylinder comprises a mother cylinder and a sub cylinder, the sub cylinder is arranged at the front end of the mother cylinder, and the diameter and the capacity of the sub cylinder are smaller than those of the mother cylinder; the needle is connected to the tail end of the sub-cylinder, the piston is inserted into the main cylinder, the piston comprises a piston head and a piston rod, and the tail end of the piston head is soft in texture and can slightly extend into the sub-cylinder.
As an improvement, the sub-cylinder is provided with scales for displaying the volume in the sub-cylinder, the main cylinder is provided with a second scale, and the numerical value of the second scale is the sum of the volume of the position where the second scale is located and the volume of the sub-cylinder.
As an improvement, an arc-shaped bulge is arranged at the joint of the female cylinder body and the sub-cylinder body, and an arc-shaped part matched with the arc-shaped bulge is arranged on the piston head.
As the improvement, the needle head cover is arranged outside the needle head.
As an improvement, the skin test needle is also provided with a spare needle head, and the specifications of the needle head and the spare needle head are respectively 5ml and 1 ml.
As an improvement, the front end of the spare needle is provided with a needle cover for protection, and the tail end is provided with a sealing film.
As an improvement, the female cylinder body adopts a thin cylinder structure, the length of the female cylinder body is increased, and the diameter of the female cylinder body is reduced.
The invention has the advantages that:
when the medicine extracting device is used, the medicine is firstly extracted into the sub-cylinder, then the needle head is inserted into the solvent, and the solvent is directly extracted into the main cylinder. The sub-cylinder body is thin, and the distance of the scale marks on the sub-cylinder body is long, so that the dosage of the medicament can be accurately displayed, and the configuration precision is improved; when the solvent is extracted into the main cylinder body, the medicine and the solvent can be uniformly mixed in the extraction process, and the mixing effect is good.
The invention can complete the preparation work of the skin test solution by using one skin test needle, greatly saves the using amount of the skin test needle and reduces the consumption of medical appliances. Meanwhile, the skin test needle has high configuration precision, high configuration speed and good medicament mixing effect, and can be widely applied to clinical skin tests.

Detailed Description
The present invention will be described in detail and specifically with reference to the following examples so as to facilitate the understanding of the present invention, but the following examples do not limit the scope of the present invention.
Example 1
The embodiment discloses a skin test needle dispenses fast, including syringe needle 1, syringe barrel 2, piston 3 and reserve syringe needle 4.
The injection cylinder 2 includes a female cylinder 21 and a sub-cylinder 22. The sub-cylinder 22 is arranged at the front end of the main cylinder 21, and the diameter and the capacity of the sub-cylinder are smaller than those of the main cylinder 21. The needle 1 is attached to the end of the sub-barrel 22. The piston 3 is inserted into the female cylinder 21.
