Abstract
The utility model relates to a funnel type indwelling needle which mainly comprises a needle handle (4) and a needle core (1); the funnel type indwelling needle is characterized in that the needle handle (4) is arranged at the upper end of a needle stem (2); a groove (3) is formed on one side of the needle stem (2); the needle core (1) is led out from the groove (3) and stuck with a needle stand (5); the upper end of the needle stand (5) is connected into a whole with a funnel-shaped conical hopper (7); a cylindrical edge is arranged at the upper end of the conical hopper (7); an annular groove is formed on the inner side wall of the cylindrical edge; a cylindrical rubber gasket (8) is clamped in the annular groove and stuck with the edge at the upper end of the conical hopper (7); and a viewing port (6) is formed on the side wall of the needle stand (5). The puncture needle directly penetrates the rubber gasket (8) during the puncture, and the needle head smoothly enters into the needle core (1) under the guidance of the inner wall of the conical hopper (7); after the puncture needle is drawn out, whether the phenomenon of backflow blood appears is observed through the viewing port (6); and the puncture needle is automatically sealed under the elastic force of the rubber gasket (8) via the puncture hole of the rubber gasket (8).
Description
Technical field
This utility model relates to a kind of funnel-type indwelling needle, is used for medical personnel's nursery work.
Background technology
Venous transfusion extensively uses son clinical, during some patient infusion, and often continuous a couple of days, cause position pinpricks such as the back of the hand, wrist close and numerous, bring misery to patient.Elderly patients particularly, long-term transfusion easily causes the local vascular sclerosis, brings difficulty to venipuncture, needs the puncture for several times could success sometimes, causes many miseries to patient.The most no blood return preventer of existing venous detaining needle, operation is complicated, narrow, and need other people to cooperate, at present, the remaining needle of China's import can address the above problem, but, there is some deficiency in these import remaining needles: the sense of stopping arranged during puncture, easily cause puncture failure, and the easy damaged blood vessel wall, calparine cap on the remaining needle is difficult for preserving, and easily pollutes.The remaining needle price of import is also expensive.
The utility model content
In order to overcome the deficiency in the background technology, this utility model provides a kind of funnel-type indwelling needle, and this funnel-type indwelling needle does not have the problem of blood return preventer when having solved venous transfusion.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of funnel-type indwelling needle, mainly by needle handle, nook closing member is formed, it is characterized in that: pin stalk upper end is provided with needle handle, pin obstructs a side and is provided with groove, nook closing member is drawn from groove, nook closing member and needle stand are bonding, the upper end of needle stand and funnel shaped taper bucket connect as one, there is an edge cylindraceous the upper end of taper bucket, there is a cannelure medial wall on this edge, columniform rubber gasket be stuck in the described cannelure and with taper bucket upper end along bonding.Have observation panel on the sidewall of needle stand.
This utility model is used for medical personnel's nursery work, reasonable in design, and the novelty that is skillfully constructed, it is little to take up room, low cost of manufacture is increased work efficiency, and is easy and simple to handle, easily puncture, do not decrease, the blood trouble tube wall, remaining needle is difficult for the advantage of pollution, and is easy to large-scale promotion application.
Description of drawings:
Accompanying drawing 1 is the structural representation of funnel-type indwelling needle.
Among the figure: the 1-nook closing member; 2-pin stalk; The 3-groove; The 4-needle handle; The 5-needle stand; The 6-observation panel; 7-taper bucket; 8-rubber skin sealing gasket.
The specific embodiment:
With reference to accompanying drawing,: a kind of funnel-type indwelling needle, mainly by needle handle 4, nook closing member 1 is formed, it is characterized in that: pin obstructs 2 upper ends and is provided with needle handle 4, pin obstructs 2 one sides and is provided with groove 3, and nook closing member 1 is drawn from groove 3, and nook closing member 1 is bonding with needle stand 5, the upper end of needle stand 5 and funnel shaped taper bucket 7 connect as one, there is an edge cylindraceous the upper end of taper bucket 7, and there is a cannelure medial wall on this edge, columniform rubber gasket 8 be stuck in the described cannelure and with taper bucket 7 upper ends along bonding.Having transparent, material on the sidewall of needle stand 5 is the observation panel 6 of lucite plastics.During puncture, puncture needle directly passes rubber gasket 8, and syringe needle enters nook closing member 1 smoothly under the guide effect of taper bucket 7 inwalls.After puncture needle extracted out, can whether observe blood back by observation panel 6.The hole that puncture needle is punctured by rubber gasket 8 sealing automatically under rubber gasket 8 self elastic force effect.Once more during liquid medicine injection, only need with thumb and forefinger clamp needle handle 4 with needle stand 5 fixing after, again puncture needle is passed rubber gasket 8, make the syringe needle of puncture needle be in the taper bucket 7 and can infuse smoothly or administration.
