Description
Technical Field
The utility model relates to a medical equipment, specifically say a medical blunt needle.
Background
In the medical field, a needle is a common device and is used in a plurality of fields of the medical industry, the conventional needles are provided with a plurality of types, namely a double-bevel needle and a side-hole needle, when in use, the double-bevel needle is easy to puncture and fall scraps to cause pollution when in medicine dispensing operation, and the side-hole needle is obviously more difficult to process than the bevel needle, so the cost is higher.
SUMMERY OF THE UTILITY MODEL
Therefore, in order to overcome the above-mentioned not enough, the utility model provides a reasonable in design, simple structure, convenient to use's medical blunt needle belongs to medical instrument, connects the needle file through the mode that reasonable adoption was bonded, makes it connect more with convenient and stable and reliable, is forty-five degrees single inclined plane at the needle point design of needle tubing, has prevented that medical staff from when dispensing the operation, and the bits are fallen in easy puncture, causes the phenomenon of pollution.
The utility model discloses a realize like this, construct a medical blunt needle, including the syringe needle, the syringe needle lower extreme has the needle file through the viscose bonding, the needle point of syringe needle is the single inclined plane of forty-five degrees.
Preferably, the needle base is internally provided with a connecting cavity which is convenient to be connected with an external injector, the needle tube inserting cavity for installing a needle is arranged inside the upper part of the needle base and is communicated with the connecting cavity, and the upper end of the needle base is internally provided with a special-shaped bonding cavity which is positioned on the upper part of the needle tube inserting cavity.
Preferably, the special-shaped bonding cavity is divided into a wide mouth cavity, an upper spherical cavity and a lower spherical cavity from top to bottom, the lower spherical cavity is communicated with the needle tube inserting cavity, and cylindrical cavities are formed between the wide mouth cavity and the upper spherical cavity and between the upper spherical cavity and the lower spherical cavity; the inner diameters of the upper spherical cavity and the lower spherical cavity are the same and are larger than the inner diameter of the cylindrical cavity.
The utility model discloses following beneficial effect has:
the utility model has reasonable design, simple structure and convenient use, is a medical blunt needle, belongs to medical apparatus and instruments, connects the needle seat by reasonably adopting a bonding mode, leads the connection to be more convenient, stable and reliable, designs a single inclined plane with forty-five degrees at the end part of the needle tube, and prevents medical staff from easily puncturing and dropping scraps to cause pollution during the dispensing operation;
simultaneously through the special-shaped chamber that bonds of reasonable design, this special-shaped bonding divide into wide oral cavity, goes up spherical chamber and lower spherical chamber, spherical chamber inserts the chamber intercommunication with the needle tubing down, and it is the same with spherical chamber internal diameter down to go up spherical chamber and be greater than cylindrical chamber internal diameter, the inner chamber through different internal diameters can be fine hold the viscose to become the solid after the viscose is done and be difficult to drop, make its bonding more fastening, guaranteed the utility model discloses a stability.
The utility model discloses the structure is ingenious, and the installation is convenient with the dismantlement, and the maintenance from now on of being convenient for makes easily simultaneously, and is with low costs, excellent in use effect, is fit for using widely.
