Abstract
The utility model discloses a medical liquid preparation needle. A small needle tube is connected with one side of a main needle head and a main needle head seat in a clamping way and used for circulating air in a bottle when liquid is prepared, so that the small needle tube, the main needle head and the main needle head seat form a whole, and the purposes of only using one needle head and simplifying the using procedure when liquid is prepared are achieved.
Description
Technical field
This utility model relates to a kind of medical dosing needle apparatus, the dosing syringe needle that especially can enough syringe needles carries out dosing.
Background technology
At present, known medical dosing needle apparatus generally adopts a main dosing syringe needle, adds the auxiliary syringe needle of intake and exhaust in use in addition.When main dosing syringe needle is extracted out or advance liquid, the required air of the normal barometric pressure in the liquid holding bottle will flow to or flows out from auxiliary syringe needle, so not only plug syringe needle program complexity in use back and forth, and need be with two syringe needles when using.
Summary of the invention
In order to overcome the deficiency of existing medical dosing syringe needle service routine complexity, this utility model provides a kind of medical dosing syringe needle, and this dosing syringe needle not only can reduce the plug number of times, simplify service routine, and only need use a syringe needle.
The technical scheme in the invention for solving the above technical problem is: the side at the main syringe needle of dosing adds a little needle tubing that is close on main syringe needle and the main needle holder, make little needle tubing and main syringe needle inject liquid mixing bottle simultaneously, the air that need pass in and out when propelling or extraction liquid so just reaches the purpose that reduces plug number of times, simplification service routine and only use a syringe needle dosing just from little needle tubing circulation.
The beneficial effects of the utility model are, only with a syringe needle dosing, and the simplification service routine, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is this utility model structure chart and implements illustration.
The figure number explanation
1, main syringe needle, 2, little needle tubing, 3, main needle holder.
The specific embodiment
In the accompanying drawings, main syringe needle (1) connects together with main needle holder (3) and the little needle tubing of a side (2) pincers.
Claims (2)
1. a medical dosing syringe needle comprises main syringe needle and main needle holder, it is characterized in that: a side of this main syringe needle, main needle holder has little needle tubing.
2. according to the medical dosing syringe needle described in the claim 1, it is characterized in that: this little needle tubing and main syringe needle, main needle holder be the company of pincers mutually.
