Abstract
The utility model discloses a precision syringe, which comprises a core rod (1), an outer sleeve (2), a piston (3), a needle holder (5), an injection needle tube (6) and a protective sleeve (7). The precision syringe is characterized in that the outer sleeve (2) and the needle holder (5) are respectively provided with a clamping groove, the clamping grooves match with each other, and a liquid medicine filter membrane (4) is fixed between the two clamping grooves. Insoluble particles in an infusion liquid medicine can be filtered precisely during use of the precision syringe by the aid of the liquid medicine filter membrane, and particle pollution in the infusion process can be reduced greatly.
Description
Technical field
This utility model relates to a kind of syringe that is used for, muscle subcutaneous to human body, intravenous drug.
Background technology
The conventional syringe that present hospital uses, core bar by mobile syringe, be used for, muscle subcutaneous, intravenous drug or extract blood and use human body, structure more complicated mostly, simultaneously owing to the particulate matter in the liquid medicine injection does not filter, particle contamination in the injection process takes place sometimes, brings bad influence can for the treatment of patient's disease.
Summary of the invention
The purpose of this utility model is to provide a kind of can carry out secondary filter to the particulate matter in the liquid medicine injection, has significantly reduced the precise injection device of the particle contamination in the injection process.
The technical solution adopted in the utility model is: a kind of precise injection device; include core bar, overcoat, piston, needle stand, injection needle, protective sleeve; it is characterized in that: described overcoat, needle stand respectively are provided with a draw-in groove that complements one another, and are fixed with a liquid medicine filtering membrane between two above-mentioned draw-in grooves.
This utility model in use can carry out secondary filter to the particulate matter in the liquid medicine injection because liquid medicine filtering membrane is arranged, and has significantly reduced the particle contamination in the injection process.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Among the figure, the 1st, core bar, the 2nd, overcoat, the 3rd, piston, the 4th, liquid medicine filtering membrane, the 5th, needle stand, the 6th, injection needle, the 7th, protective sleeve.
The specific embodiment
The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:
This utility model precise injection device includes core bar 1, overcoat 2, piston 3, needle stand 5, injection needle 6, protective sleeve 7 as can be seen from Figure 1, respectively is provided with a draw-in groove that complements one another on overcoat 2, needle stand 5, is fixed with a liquid medicine filtering membrane 4 between two draw-in grooves.
This utility model product provides multiple model to select, and during clinical use, can select the different precise injection device of capacity according to patient's concrete condition.
This utility model is a kind of simple and practical, and handling safety is cheap, is easy to the medical apparatus and instruments accepted by medical personnel, and safe and reliable, precise injection is easy in the medical device industry penetration and promotion.
