Description
Technical field
This utility model belongs to technical field of medical instrument, is specifically related to a kind of Novel intramuscular injection
Syringe needle.
Background technology
In long-term clinical nursing activity, venous transfusion, intramuscular injection, subcutaneous injection etc. are
Basic operation in nursery work, and wherein intramuscular injection is the height that clinical nursing activity uses
One of frequency operation, before intramuscular injection operates, needs to use muscle injector to carry out medicinal liquid
Extraction or preparation.Intramuscular injection empty needle is taken out medicine and is divided into two kinds: one is extraction ampoule inner liquid medicine
Direct injection, another kind is that puncture seal bottle carries out the configuration of medicinal liquid after extraction solvent, then takes out
Go out the medicinal liquid after being sufficiently mixed to inject.
After the entry needle of intramuscular injection punctures through the rubber stopper preparating liquid of air-tight bottle, re-use
This entry needle carries out intramuscular injection, it may appear that needle point rust acutance reduces, and the skin that stretches tight is difficult to,
And the pain of patient strengthens；Even so that inspire the intense strain of patient, so patient under
The pavid psychology of intramuscular injection operation；And the entry needle after Chuan Ciing easily remains rubber
Plug chip, is unfavorable for that the intramuscular injection to patient operates.At present for solving these nursing problems,
The injection needle puncturing through air-tight bottle rubber stopper is generally abandoned by the clinical nursing activity person of one line,
The syringe needle the most more renewed is injected.Inventor of the present utility model finds through research,
During entry needle is separated from syringe, hands easy false touch entry needle when changing injection needle
Needle nipple and the position such as pintle, thus cause liquid medicine contamination, run counter to sterile working's principle, with
Time when changing injection needle, easily there is pricking wound, be greatly increased in occupational exposure and institute sense
The probability of dye.
Utility model content
For the empty needle of rust, meeting after the direct hands replacing puncture seal bottle that prior art exists
The most directly liquid medicine contamination is caused at false touch empty needle position, and easily causes clinical staff to wear
Stabbing the technical problem of increase, this utility model provides a kind of syringe needle of new muscle.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of syringe needle of new muscle, including the first entry needle, described first entry needle includes
First needle stand, the first needle body and the first needle point, described first needle body is cavity, and with
One needle point and the first needle stand are formed in one structure, described first needle stand include the first connection end and
Second connects end, and the described first inner wall surface connecting end is provided with the first female thread, and described second
Connect end connect have dismountable second entry needle, described second entry needle include the second needle stand,
Second needle body and the second needle point, described second needle body is cavity, and with the second needle point and the second pin
Seat is overall structure, and the internal diameter of described second needle body is more than the external diameter of the first needle body, and first
Needle point is away from the second needle point 0.5～1cm.
Further, described second needle stand includes that the 3rd connection end and the 4th connects end, described the
Three inner wall surface connecting end are provided with the second female thread, and the described second outer surface connecting end is provided with
First external screw thread, described first external screw thread and the second female thread cooperate, and be screwed connection
First entry needle and the second entry needle.
Further, described 4th connection end being installed with the second flank, described second flank has
Two, for circular and be mutually correspondingly arranged.
Further, the interior diameter of described second flank is 1.5～2.5cm.
Further, the described first outer surface connecting end is installed with the first flank, and described first
Flank has two, and is mutually correspondingly arranged.
The beneficial effects of the utility model are: the design of double injection pin, the first of the first entry needle
In second needle body of the second entry needle that needle body inserts cavity, utilize the second needle point puncture seal bottle
Rubber stopper, the first needle body and the second needle body stretch in air-tight bottle extraction medicinal liquid simultaneously, due to the
One entry needle can be connected with syringe by the first female thread of the first connection end, and medicinal liquid passes through
First entry needle goes directly in syringe, then rust and possible blocking have the second note of rubber chip
Penetrate pin removal, with the first entry needle, patient is carried out intramuscular injection, can effectively solve to change note
During penetrating this troublesome operation of empty needle, the liquid medicine contamination that caused and occupation puncture can be reduced
The generation of wound.
