Description
Technical field
This utility model design syringe, is specifically related to a kind of stagewise syringe.
Background technology
As everyone knows, hybrid injection wanted by two kinds or two or more medicines, the definite test such as clinical must be obtained support and just can implement, react to each other because easily produce between medicine, with the risk of the unknown, but often need again injection two kinds or two or more medicine when anesthesia surgery, just can reach good effect, when not obtaining definite clinical test such as grade and supporting, sample can only be divided to inject, and current technical point sample injection, need to use multiple needle tubing, need multiple syringe needle simultaneously, so not only can bring inconvenience to doctor, and more misery can be caused to patient.
Utility model content
This utility model provides a kind of stagewise syringe, it realizes point sample injection of two or more medicine by a syringe needle, solve and do not obtain at present definitely clinically waiting two kinds of test support or two or more medicines to inject simultaneously, the technical problem needing to need to use when injecting spininess pipe and syringe needle and could divide sample to inject, have manufacture simply, cost is low, simple to operate, can alleviate the advantages such as patient suffering.
This utility model is achieved in that
Stagewise syringe, comprise syringe needle head and syringe needle tube portion, it is characterized in that: described syringe needle tube portion comprises several one-level needle tubing be mutually socketed to form up and down, secondary needle tubing and multistage needle tubings, the piston that can do upper and lower piston movement together with needle tubing at the corresponding levels in next stage needle tubing is equipped with bottom described secondary needle tubing and multistage needle tubing, piston bottom described secondary needle tubing and multistage needle tubing is equipped with sealing device, and described secondary needle tubing and the inwall of multistage needle tubing are provided with the locking mechanism matched with upper level needle tubing outer wall; Described syringe needle head comprises entry needle, and described entry needle is located in the bottom of one-level needle tubing; Described sealing device is arranged on above the vertical line of entry needle.
Described multistage needle tubing is three grades of needle tubings or level Four needle tubing.
The stagewise syringe of this programme, does not change syringe needle and just can not obtain definite clinical two kinds or the two or more medicines waiting test to support to patient's injection, arrived better treatment or anaesthetic effect.After drug injection in one-level needle tubing completes, the sealing device of secondary needle tubing punctures by the entry needle being located in one-level needle tubing, then can inject the medicine in secondary needle tubing, remove the locking mechanism on secondary needle tubing, needle tubing then more than secondary needle tubing can move downward together, by the drug injection in secondary needle tubing in body, after having injected, the sealing device of three grades of needle tubings punctures by the entry needle being located in one-level needle tubing, then operation is above repeated, just can by all drug injection in this needle tubing in body.
Further, described locking mechanism be arranged on secondary needle tubing and multistage needle interior wall groove and be arranged on upper level needle tubing outer wall with the projection of groove match.
Groove on the inwall of secondary needle tubing and multistage needle tubing and after overlapping with the projection being arranged on upper level needle tubing outer wall, can determine the volume in this needle tubing.So only need to arrange scale on one-level needle tubing wall, and secondary needle tubing and multistage needle tubing wall on can not scale be set.
Further, described entry needle is tip-shape entry needle up and down.Upper syringe needle employing is tip-shape can puncture sealing device like a cork.
Further, the shape of described piston is up big and down small inverted cone, and described sealing device is the encapsulating film being arranged on piston base.Adopt this programme that the drug injection in needle tubing can be made complete, can not waste be caused.
Further, sealing device be arranged on the side of piston base can the seal cover of folding.Adopt the sealing device of this programme that needle tubing can be reused, do not waste.
The beneficial effects of the utility model are: the stagewise syringe of (1) this programme, do not change syringe needle and just can not obtain definite clinical two kinds or the two or more medicines waiting test to support to patient's injection, arrive better treatment or anaesthetic effect.Inject bottommost needle tubing in medicine time, remove the locking mechanism between bottommost needle tubing and a upper needle tubing, all needle tubings then on bottommost needle tubing can move downward with the piston in a upper needle tubing of bottommost needle tubing, by the drug injection in bottommost needle tubing in body, after drug injection in bottommost needle tubing completes, sealing device bottom a upper needle tubing punctures by the entry needle being located in the needle tubing of bottommost, then can inject the medicine in this needle tubing, then operation is above repeated, just can by the drug injection in this needle tubing in body.
(2) adopt this programme that the drug injection in needle tubing can be made complete, can not waste be caused.Upper syringe needle employing is tip-shape can puncture sealing device like a cork.
