Description
Technical Field
The utility model relates to the medical instrument technology, in particular to a skin superficial injector.
Background
At present, the traditional medical injector is adopted for injecting the medicament into the skin superficial tissues, the injection needle heads of the traditional medical injector are all straight needle heads, horizontal needle insertion (the horizontal needle insertion refers to an angle approximately parallel to the surface of the skin) is difficult to implement when the medicament is injected into the skin superficial tissues, and the needle insertion is over-deep due to inertia of force application when the medicament is inserted, so that the injection needle heads cannot accurately reach the skin superficial tissues, and poor dispersion of the injected medicament is easy to cause. In various treatments of the skin, there is a need to use a syringe to effectively disperse the drug in the superficial tissues, such as superficial infiltration anesthesia, and the like, and such injection operations can affect the medication effect of the patient. The skin superficial injection medicine needs intermittent injection, after each injection is completed, the injector is placed in an object tray beside the injector, a nurse is easy to be pricked by a bare needle when taking and placing the medicine, and the bare needle is also easy to be polluted.
Disclosure of Invention
Aiming at the defects in the prior art, the technical problem to be solved by the utility model is to provide the skin superficial injector which can improve the dispersion effect of the injection medicine in the superficial tissues and can prevent the exposure of the injection needle during the intermittent period of the injection medicine.
In order to solve the technical problems, the utility model provides a skin superficial injector, which comprises an injection needle cylinder, an injection needle head, an injection push rod and a piston arranged in the injection needle cylinder; the left end of the injection needle cylinder is provided with a needle joint, and the injection needle head is arranged on the needle joint at the left end of the injection needle cylinder; the left end of injection push rod and piston rigid coupling, the right-hand member of injection push rod stretches out the right-hand member nozzle of syringe to the right side, its characterized in that:
the injection needle consists of a needle left section and a needle right section, the whole injection needle is in a two-fold shape, and the included angle between the needle left section and the needle right section is 140-170 degrees;
the needle joint is provided with a protective sleeve which can stretch left and right, the protective sleeve is a shapable corrugated pipe, the whole injection needle is positioned in the lumen of the protective sleeve, the protective sleeve is contracted rightwards to the shortest time, and the left section of the needle of the injection needle completely extends out of the protective sleeve.
Further, the length of the left needle section of the injection needle is longer than the length of the right needle section.
Further, the included angle between the left needle section and the right needle section of the injection needle is 155 degrees.
The skin superficial injector provided by the utility model adopts the two-fold linear injection needle, so that the injection needle can horizontally enter the skin superficial tissue at an angle almost parallel to the surface of the skin, the injection needle can accurately reach the skin superficial tissue, the dispersion effect of injection medicine in the skin superficial tissue is improved, the injection needle can be sleeved by the sheath, the injection needle can be prevented from being exposed during the intermittent period of injection medicine, the exposed needle can be prevented from being stabbed by nurses when the medicine is taken and placed, and the needle can be prevented from being polluted.

FIG. 2 is a front view of a superficial dermal syringe according to an embodiment of the present utility model with the sheath retracted to the right to a minimum;
fig. 3 is a schematic view of the structure of an injection needle in the skin superficial injector according to the embodiment of the present utility model.
Detailed Description
The following description of the embodiments of the present utility model is provided in detail, but the embodiments are not limited to the embodiments, and all the similar structures and similar variations using the present utility model should be included in the protection scope of the present utility model, and the reference numerals in the present utility model indicate the relationships.
As shown in fig. 1-2, the superficial skin injector provided by the embodiment of the utility model comprises an injection needle cylinder 1, an injection needle head 2, an injection push rod 3 and a piston 4 arranged in the injection needle cylinder; the left end of the injection needle cylinder 1 is provided with a needle joint, and the injection needle head 2 is arranged on the needle joint at the left end of the injection needle cylinder 1; the left end of the injection push rod 3 is fixedly connected with the piston 4, and the right end of the injection push rod 3 extends to the right end cylinder opening of the injection cylinder 1;
the injection needle 2 consists of a needle left section 21 and a needle right section 22, the whole injection needle is in a two-fold shape, and the included angle between the needle left section 21 and the needle right section 22 is 140-170 degrees;
the needle joint is provided with a protective sleeve 11 which can stretch left and right, the protective sleeve 11 is a plastic corrugated pipe, the whole injection needle 2 is positioned in the pipe cavity of the protective sleeve 11, and the protective sleeve 11 is contracted rightwards until the left needle section 21 of the shortest injection needle 2 completely extends out of the protective sleeve 11.
The embodiment of the utility model is used for improving the dispersion of the injection medicine in the superficial tissues, and the application method is as follows:
the sheath tube 11 is retracted to the right to the minimum, so that the left needle section 21 extends completely out of the sheath tube 11 (the sheath tube can remain retracted due to its shapeable nature), and then the injection needle 2 is inserted into the medicament vial, and then the injection plunger 3 is pulled to withdraw the medicament.
After the medicine is extracted, the nurse can implement horizontal needle feeding at an angle almost parallel to the skin surface due to the adoption of the two-fold injection needle, so that the injection needle can accurately reach the skin superficial tissue, the dispersion effect of the injection medicine in the superficial tissue is improved, after the required amount of the medicine is injected, the injection needle 2 is withdrawn, the protective sleeve 11 is pulled leftwards, the injection needle 2 integrally retracts into the protective sleeve 11, and then the injector is put into a tray of an injector for waiting for subsequent injection.
