Detailed description of the invention
Fig. 1 is a kind of schematic diagram of remaining needle of one embodiment of the utility model；
Fig. 2 is the enlarged drawing of the part-structure in Fig. 1；
Fig. 3 is the construction profile of the fixed part in Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 schematically shows a kind of a kind of remaining needle of embodiment according to the present utility model, Fig. 2 amplification display
Part-structure in Fig. 1.As shown in Figure 1, the remaining needle includes 1, connector 2 of a conduit and a fixed part 3, wherein
Conduit 1 be it is hollow, a steel needle 11 can be inserted in one end, be specially connected with a tee tube 22 in one end of conduit 1,
And the both ends of them of tee tube 22 are separately connected conduit 1 and steel needle 11, and steel needle 11 can be inserted by tee tube 22 and be led
In pipe 1, in addition, being also provided with the positions such as needle handle, on steel needle 11 can easily be held when being inserted into steel needle 11.
Then pass through an extension tube 21 in last one end of tee tube 22 and be connected with a connector 2, wherein extension tube 21
Length, which can according to need, is configured selection, and connector 2 is then for connecting infusion device.And it is removable by screw thread on connector 2
One fixed part 3 is installed with unloading, center tap 2 is equipped with external screw thread, and corresponding internal screw thread is then equipped on fixed part 3.
In addition, conduit 1, tee tube 22 and extension tube 21 are generally transparent.
The other end of conduit 1 has a thinner nozzle, and liquid is input to patient's body from nozzle when in use.And
In present embodiment, some side openings 12 are provided on the tube wall of the side at nozzle.Wherein, the quantity of side opening 12 is preferably 2-
It 5, is irregularly dispersed on the tube wall around at the nozzle of conduit 1.On the one hand the presence of side opening 12 can increase infusion
Speed, on the other hand can be improved the patency of infusion.
Fig. 3 shows the side structure of the fixed part in Fig. 1.As shown in figure 3, fixed part 3 includes a hollow compressing
Column 31, wherein compressing column 31 is preferably made of soft material.And internal screw thread, the internal screw thread energy are equipped in the inside of compressing column 31
Enough match with the external screw thread on connector 2 is removably installed.
Wherein side in the periphery of compressing column 31 is mutually Nian Jie with a longer adhesive tape 32, and the other side is then equipped with a nothing
Bacterium sliver 33, wherein the intermediate position of adhesive tape 32 is mutually Nian Jie with compressing column 31, and both ends then extend respectively into the two of compressing column 31
Side；And sterile sliver 33 cover compressing column 31 periphery side after, both ends respectively compressing column 31 two sides and glue
With 32 mutually bonding.
The both ends of adhesive tape 32 are pasted with a protection band 34, wherein the viscous of adhesive tape 32 will not be damaged to by pasting protection band 34
Property.Do not use adhesive tape 32 when, protection band 34 can protective glue band 32, make its maintain viscosity, and consolidated using adhesive tape 32
Periodically, protection band 34 can be taken off, adhesive tape 32 can be pasted onto required place.
In addition, in the outside at the intermediate position of adhesive tape 32, the specially outside at the position mutually Nian Jie with compressing column 31, preferably
