Abstract
The utility model discloses an indwelling needle with a flexible duct base, which comprises a duct, wherein the inside of the back end of the duct is connected with an inner metallic pipe and the outside is connected with a duct base, an outer metallic pipe is arranged between the back end of the duct and the duct base, the inner metallic pipe and the outer metallic pipe cover the inner wall and the outer wall of the back end of the duct, and the duct base is made from flexible material. The duct base (3) of the utility model is made from flexible material, which prevents children from bruise caused by moving.
Description
Technical field
This utility model relates to a kind of soft catheter block remaining needle.
Background technology
Present remaining needle mainly includes puncture needle, conduit, catheter block, long duct and infusion connector assembly, and catheter block is connected rear end of conduit, and puncture needle comprises the notch needle tubing that is plugged in conduit and the catheter block, the notch needle stand that is exposed to catheter block.After medical personnel use venous indwelling at the patient's vein vascular puncture, puncture needle to be extracted from catheter block rear end and conduit, comparatively softish duct portion is kept somewhere in the patient's vein blood vessel, carries out continuously to the patient or transfusion discontinuously by conduit.Because it is flexible that soft conduit has, when remaining needle placed vein, conduit can be tortuous synchronously with vein, makes the injection site still can freely move, to alleviate the sense of discomfort of patient when using.
In the prior art, conduit be tubaeform metal tube and the outside catheter block folder by inside establish realize localized, because conduit is soft, if catheter block also for soft then conduit and metal tube are can't be fixed, therefore present catheter block all has hard material to make.But when child or child used remaining needle, because they are very active, rigid catheter block caused their damaging probably.
Summary of the invention
This utility model purpose is: a kind of soft catheter block remaining needle is provided, and the catheter block of this remaining needle adopts soft material to make, and has avoided child or child because of active damaging of causing.
The technical solution of the utility model is: a kind of soft catheter block remaining needle, comprise conduit, the rear end of conduit is internally connected with interior metal tube, the rear end of conduit is externally connected to catheter block, be provided with between the rear end of described conduit and the catheter block and be provided with outer metal tube, interior metal tube and outer metal tube are wrapped on the inside and outside wall of rear end of conduit, and catheter block is made by soft material.
The further technical scheme of this utility model is: a kind of soft catheter block remaining needle, comprise conduit, the rear end of conduit is internally connected with interior metal tube, the rear end of conduit is externally connected to catheter block, be provided with between the rear end of described conduit and the catheter block and be provided with outer metal tube, interior metal tube and outer metal tube are wrapped on the inside and outside wall of rear end of conduit, and catheter block is made by soft material; Metal tube comprises the linkage section that is connected with conduit, the loudspeaker section of stretching out conduit respectively with outer metal tube in described, and the loudspeaker section of outer metal tube and the inner hole wall of catheter block closely cooperate, and the loudspeaker section of interior metal tube closely cooperates with the loudspeaker section of outer metal tube.
This utility model advantage is:
1. catheter block of the present utility model adopts soft material to make, and has avoided child or child because of active damaging of causing.
2. because catheter block of the present utility model adopts soft material to make, therefore adopt inside and outside metal tube parcel conduit can realize the fixing of conduit, avoided being the generation that the soft conduit that causes can't fixed situation because of conduit and catheter block.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is a sketch map of the present utility model;
Fig. 2 is the connecting portion component between conduit and the catheter block among Fig. 1.
Wherein: 1 conduit; Metal tube in 2; 21 linkage sections; 22 loudspeaker sections; 3 catheter blocks; 4 outer metal tubes; 41 linkage sections; 42 loudspeaker sections.
The specific embodiment
Embodiment: as depicted in figs. 1 and 2, a kind of soft catheter block remaining needle, comprise conduit 1, the rear end of conduit 1 is internally connected with interior metal tube 2, the rear end of conduit 1 is externally connected to catheter block 3, be provided with between the rear end of conduit 1 and the catheter block 3 and be provided with outer metal tube 4, interior metal tube 2 and outer metal tube 4 are wrapped on the inside and outside wall of rear end of conduit 1, and catheter block 3 is made by soft material.
Because catheter block of the present utility model 3 adopts soft materials to make, therefore adopt inside and outside metal tube 2 and 4 parcel conduits 1 can realize the fixing of conduit 1, avoided being the generation that the soft conduit that causes 1 can't fixed situation because of conduit 1 and catheter block 3.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
Claims (2)
1. soft catheter block remaining needle, comprise conduit (1), the rear end of conduit (1) is internally connected with interior metal tube (2), the rear end of conduit (1) is externally connected to catheter block (3), it is characterized in that: the rear end outer setting of described conduit (1) has outer metal tube (4), interior metal tube (2) and outer metal tube (4) are with the rear portion clamping of conduit (1), and catheter block (3) is made by soft material.
2. according to the described soft catheter block remaining needle of claim 1, it is characterized in that: metal tube (2) comprises the linkage section (21,41) that is connected with conduit (1), the loudspeaker section (22,42) of stretching out conduit (1) respectively with outer metal tube (4) in described.
