Example 1

The embodiment provides a simple aspirator device, as shown in fig. 1-4, including a needle sheath 1 for sheathing on an injection needle 2, the needle sheath 1 includes a sheathing part 11 located at the tail end of the needle sheath 1 and an end 12 located at the head end of the needle sheath 1 and being in a closed shape, the sheathing part 11 and the end 12 are in an integrated structure, and in a normal state, the needle sheath 1 serves as a protective sleeve for the injection needle 2 to prevent the injection needle 2 from causing a puncture wound to a person. A sleeve cavity 11a for sleeving the injection needle 2 is formed in the sleeving part 11, the end 12 is closed, a cavity 12a is formed in one end far away from the sleeve cavity 11a, an annular convex ring 121 is integrally formed between the sleeve cavity 11a and the cavity 12a, a circular truncated cone-shaped installation cavity 12b is formed in the inner side of the convex ring 121, and the cavity 12a and the sleeve cavity 11a are communicated through the installation cavity 12 b.

In this embodiment, the outer surface of the end head 12 is provided with a notch 12c, the notch 12c is in a ring-shaped groove structure, and the notch 12c is aligned with the cavity 12a, so that the medical worker can cut the end head 12 from the notch 12c by using the surgical forceps, and the rubber plug 13 is exposed.

Specifically, the inner surface of the convex ring 121 is conical, the inner diameter of the mounting cavity 12b near one end of the cavity 12a is larger than the inner diameter of the cavity 12a, and the inner diameter of the mounting cavity 12b near one end of the sleeve cavity 11a is larger than the outer diameter of the needle tube part of the injection needle 2 and smaller than the inner diameter of the cavity 12a, so that the injection needle 2 can extend into the sleeve cavity 11a through the small-diameter end of the mounting cavity 12b under the guidance of the inner wall of the mounting cavity 12b when inserted from the head end of the cut needle sleeve 1.

Further, plug 13 has been cup jointed in installation cavity 12b, the oral area position department of needle cover 1 tail end has cup jointed and has attracted pipe 3, when syringe needle 2 was inserted from the needle cover 1 head end that is cut, syringe needle 2 passed from plug 13, make needle cover 1 and syringe needle 2 be in the encapsulated situation of inseparable laminating, prevent that the gas leakage phenomenon from appearing in the junction of syringe needle 2 and needle cover 1, thereby make syringe needle 2 when cup jointing the syringe, can make the other end that attracts pipe 3 produce suction through the pull syringe, reach the suction effect.

When the simple aspirator device is used, the injection needle 2 sleeved with the needle sleeve 1 is sleeved on a syringe, then, the head end of the sleeve joint part 11 is cut off by using medical forceps to aim at the incision groove 12c, so that the head end of the sleeve joint part 11 is opened, finally, the head part of the injection needle 2 is inserted from the head end of the incised needle sleeve 1, at the moment, the injection needle 2 is inserted, the injection needle 2 penetrates through the rubber plug 13 and extends into the sleeve cavity 11a, then the tail end of the needle sleeve 1 is sleeved with a suction tube 3, the other end of the suction tube 3 extends into the blood to be extracted, at the moment, the syringe is drawn to suck the blood into the syringe through the suction tube 3, in the process of suction, the rubber plug 13 enables the needle sleeve 1 and the injection needle 2 to be in a sealing state, so that the phenomenon that blood cannot be sucked due to air leakage at the joint of the needle sleeve 1 and the injection needle 2 in the process of suction is prevented.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
