Description
Technical field
This utility model relates to the syringe of one-handed performance formula safety.
Background technology
In every-day medical, local infiltration anesthesia Application comparison is extensive, and general anaesthetic dosage is little, and the syringe capacity therefore for local anesthesia is not generally less than 10ml very much; In addition, carry out in local infiltration anesthesia process, whenever needs inject before narcotics, all will inject again without during blood backflow through pumpback test inspection, avoid anaesthetic directly to enter blood.
Along with the extensive use of ultrasonic technique, some local infiltration anesthesias all can be carried out under ultrasound guidance, such as, local infiltration anesthesia before some preoperative brachial plexus nerve blocks, the aspiration biopsy of ultrasound guidance superficial tissue etc.These means have the advantages such as safe, efficient.But due to the hand-held ultrasonic probe of operator one, the hand-held anesthetic syringe of another, therefore can only single-hand operated syringe, in order to avoid there is syringe needle damage important organ when both hands exchange.
But, the piston tail of conventional syringe is mostly smooth, easy propelling, then need at least two fingers just can complete with joint efforts during extraction, when using traditional local anesthesia set, as wanted to realize one-handed performance, operator need use thumb, forefinger and middle finger grip shell portion, nameless and little finger grips piston tail mainly through shoulder joint, the coordination exercise of elbow joint completes the propelling of piston and extracts action out, nameless and little finger grips more clumsy when piston tail carries out advancing and extract out action and movable amplitude is less, cause single-hand operated syringe carry out pumpback test difficulty very large, and easily cause danger.
Utility model content
Not enough for prior art, the syringe that this utility model provides a kind of one-handed performance simple, convenient and safe.
For solving the problems of the technologies described above, this utility model is by the following technical solutions: the syringe of one-handed performance formula safety, comprise cylindrical shell and plunger rod, described cylindrical shell has inner chamber, described inner chamber has internal chamber wall, described plunger rod comprises the plunger rod head set gradually, plunger rod body and plunger rod afterbody, described plunger rod head is positioned among the inner chamber of cylindrical shell, described plunger rod head and internal chamber wall closely cooperate, described plunger rod afterbody is positioned at outside the inner chamber of cylindrical shell, described plunger rod afterbody is provided with finger lasso, plunger rod afterbody is driven to move when described finger lasso moves, plunger rod body is driven to move when described plunger rod afterbody moves, plunger rod head is driven to move among the inner chamber of cylindrical shell when described plunger rod body moves.
The beneficial effect of the syringe of the one-handed performance formula safety that this utility model provides is: owing to comprising cylindrical shell and plunger rod, described cylindrical shell has inner chamber, described inner chamber has internal chamber wall, described plunger rod comprises the plunger rod head set gradually, plunger rod body and plunger rod afterbody, described plunger rod head is positioned among the inner chamber of cylindrical shell, described plunger rod head and internal chamber wall closely cooperate, described plunger rod afterbody is positioned at outside the inner chamber of cylindrical shell, described plunger rod afterbody is provided with finger lasso, plunger rod afterbody is driven to move when described finger lasso moves, plunger rod body is driven to move when described plunger rod afterbody moves, plunger rod head is driven to move among the inner chamber of cylindrical shell when described plunger rod body moves, therefore single can being inserted in finger is pointed in lasso, achieve single finger and complete plunger rod propelling, extract action out, when carrying out local anesthesia injection, the thumb of operator, middle finger and nameless gripping needle tubing part, index finger cover enters in finger-stall circle, take hypothenar as the strong point, the motion of syringe entirety has been driven by wrist flexor, the flexor of forefinger drives the propelling of plunger rod and extracts action out, when simple forefinger operation post stopper rod advances and extracts action out, not only flexibly and also movable amplitude larger, meet the feature of body mechanics, thus the difficulty that single-hand operated syringe carries out pumpback test reduces greatly, avoid causing danger.
The outer surface of further described finger lasso is enclosed with one deck soft rubber, more comfortable when operation post stopper rod being advanced and extracts action out.
Further described finger lasso is rounded, described finger lasso is by making the elastomeric material of deformation, circular finger lasso meets the appearance profile of finger more, and point lasso by making the elastomeric material of deformation, make when finger is greater than finger lasso, finger lasso can be large by finger support, thus finger lasso can adapt to the finger of different size.
The outer surface of further described cylindrical shell is provided with and points the depression matched, more comfortable when making operator hold cylindrical shell.
The outer surface of further described cylindrical shell is provided with the scale raised up, make operator inject time, the amount of movement of plunger rod can be known according to scale, thus by injection amount control more accurate.
The afterbody of further described cylindrical shell is provided with the stipule extended to both sides, and the finger of operator can also be coordinated with stipule, thus more stable when operator completes syringe mass motion.
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
