Abstract
The utility model relates to a medical instrument, in particular to a medical injector for intravenous injection. The medical injector comprises an injector cylinder, a syringe needle and a propulsion plug, wherein the syringe needle is connected with the front end of the injector cylinder and is communicated with an inner cavity of the injector cylinder, and the propulsion plug is located inside the injector cylinder. The medical injector is characterized in that a hollow steel needle which is in the same shape as the syringe needle is arranged outside the syringe needle, the steel needle is located at an opening of one side of the syringe needle, and the liquid flowing-out end of the syringe needle is arranged on the side of the syringe needle. Due to the structure, the medical injector effectively prevents rubber particles, fibers, and drug solution contaminated by bacteria outside the steel needle from entering into blood vessels along with drug solution from the syringe needle, reduces damage to patients to the greatest extent, ensures physical rehabilitation of the patients, and improves treatment progress for the patients.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind ofly is used for intravenous injector for medical purpose.
Background technology
The intravenous injection medicinal liquid is one of important means in the treatment; In the layoutprocedure of some intravenous injection medicinal liquids commonly used, all the medicine bottle cap rubber stopper to be passed repeatedly for several times, so clinically; Rubber particle, fiber and the germ contamination medicinal liquid that just will have inevitably in the outside of syringe needle; Existing most disposable intravenous injector is that syringe needle is directly advanced by in injector's body, and like this, a large amount of rubber particles, fiber and antibacterial are both with the medicinal liquid intravasation; Because the diameter of this microgranule is greater than the diameter of blood capillary, thereby can bring various disease of capillaries for the patient.
Summary of the invention
The purpose of this utility model provides a kind of rubber particle, fiber and germ contamination medicinal liquid of preventing via the injector for medical purpose of syringe needle with the medicinal liquid intravasation.
This utility model is that the technical scheme that the technical solution problem is adopted is:
Injector for medical purpose; Comprise syringe, be connected the syringe needle of syringe front end and syringe intracavity inter-connection and be positioned at the promotion plug of syringe; It is characterized in that: the outside of said syringe needle is provided with the draw point of the hollow identical with the syringe needle shape; The dismountable outside that is sleeved on syringe needle of said draw point, said draw point is positioned at a side opening of syringe needle liquid outlet.
Owing to adopted said structure; The described injector for medical purpose of this utility model effectively prevent to be infected with rubber particle, fiber and germ contamination medicinal liquid in the draw point outside via syringe needle with the medicinal liquid intravasation; Reduce injury to greatest extent to the patient; Guarantee the patient's body rehabilitation, improve patient's treatment progress.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
As shown in Figure 1, the described injector for medical purpose of this utility model comprises syringe 1, is connected the syringe needle 2 of syringe 1 front end and syringe 1 intracavity inter-connection and is positioned at the promotion plug 3 of syringe 1; Medicinal liquid is released by syringe needle 2 through promotion plug 3, and the outside of said syringe needle 2 is provided with the draw point 4 of the hollow identical with the syringe needle shape, said draw point 4 dismountable outsides that are sleeved on syringe needle 2; Said draw point 4 is positioned at a side opening of syringe needle 2 liquid outlets, when syringe needle 2 inserts medicine bottle suction medicine, medicinal liquid is got in the syringe needle 2; During injection; After the said injector for medical purpose of this utility model passes the rubber stopper of medicine bottle, can the draw point 4 that rubber particle, fiber and antibacterial are infected with in the outside be taken off, again the patient is injected; Prevent that effectively pathogenic bacteria from getting into human body, guaranteed patient's treatment to greatest extent.
