The novel injector has the advantages of simple structure, convenient use, simple and convenient sterilization operation, as well as time and labor conservation, and alleviates the working strength of nursing personnel. When using the injectors to inject patients, nursing personnel can strictly control injection depth to avoid medical negligence because of easy grasp and clear view.

Description

Novel injector

Technical field

This utility model relates to a kind of medical supplies, particularly relates to a kind of novel injector.

Background technology

The syringe of present clinical use, its outer surface are shiny surface, when hands uses syringe, points and badly control, firmly, usually need the another hands to catch the needle tubing co-operate, and hands will block nursing staff's the visual field like this, make operate inconvenient.Also have, the nursing staff is when injecting for patient, and the weight of acupuncture treatment is wayward, careless slightlyly will lead to adverse consequencess such as neural paralysis, entry needle eye irritation, the nursing staff who has more just worked, the weight of more difficult grasp injection causes malpractice easily.In addition, the nursing staff is when carrying out intramuscular injection to patient, must to carry out disinfection to patient's skin earlier, usually the nursing staff makes cotton ball soaked in alcohol in advance or dips in the cancellation venom with cotton rod before injection and carries out disinfection the time, this operational approach extremely bothers, waste time and energy, increased working strength to the nursing staff.

The utility model content

In order to address the above problem, this utility model provides a kind of novel injector, during injection, holds easily, gets a clear view, and can strictly control the weight of injecting, and avoids malpractice to take place, and easy, the time saving and energy saving novel injector of sterilizing operation.

The technical solution adopted in the utility model is: a kind of novel injector, comprise injection needle, injection needle, piston, piston push rod and pin medicated cap, it is characterized in that the injection needle outer surface is provided with one around the injection needle strip projected parts in one week, be fixed with no volva on the injection needle, be fixed with sterilized cotton ball at pin crown end.Projection is arranged on injection needle total length 1/3rd places, near the first end of entry needle.No volva is the cylinder that an end is provided with cylinder table, and the through hole corresponding with injection needle runs through cylinder table and cylindrical center.

Advantage of the present utility model is: this novel injector is simple in structure, and is easy to use, and sterilizing operation is easy, time saving and energy saving, alleviated nursing staff's working strength.The nursing staff holds when using it to give patient injection easily, gets a clear view, and weight that can strict control injection avoids malpractice to take place.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Extremely shown in Figure 5 as Fig. 1, a kind of novel injector, comprise injection needle 1, injection needle 2, piston 3, piston push rod 4 and pin medicated cap 5, it is characterized in that injection needle 1 outer surface is provided with a strip projected parts 6 around 1 one weeks of injection needle, be fixed with no volva 7 on the injection needle 2, be fixed with sterilized cotton ball 8 on pin medicated cap 5 tops.Projection 6 is arranged on injection needle 1 total length 1/3rd places, near injection needle 2 one ends.No volva 7 is the cylinder that an end is provided with cylinder table, and the through hole corresponding with injection needle 2 runs through cylinder table and cylindrical center.

Before giving patient injection, must carry out disinfection by first skin to patient, at this moment take off pin medicated cap 5, carry out disinfection, then the hand-held injection needle 1 of nursing staff with sterilized cotton ball 6, when injection needle 2 is thrust patient's intramuscular and reaches no volva 5 places, will be stopped and to continue to thrust that at this moment, nursing staff's finger is pinned the projection 6 of injection needle 1 outer surface by no volva 5, cooperate palm injectable drug in the patient body, after injection finished, finger was pinned projection 6, cooperated palm to extract injection needle 2 and got final product.
