Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of venous detaining needle.
Background technology
Venous detaining needle is a kind of syringe needle being applied to clinical transfusion, uses when being usually used in infant transfusion, can alleviate the misery that infant brings because of scalp repeated localised puncture, also can alleviate the nurse of clinical nurse simultaneously.
Traditional venous detaining needle is primarily of syringe needle and the needle tubing that is sheathed on outside syringe needle, and axial one end of syringe needle is skewed fluid output port, and the other end is provided with the needle holder with syringe needle socket connection, be provided with outside needle tubing can with the transfusion tube joint of syringe needle conducting and holding plate.Traditional syringe needle is revealed in outside needle tubing, and medical personnel easily cause accidental injury when implementing contact pin to patient, thus occurs infecting, and this type of venous detaining needle also easily causes accidental injury to reclaimer operation personnel when reclaiming.
Summary of the invention
For the deficiency that prior art exists, this utility model provides a kind of use safety, prevents causing accidental injury to medical personnel, is convenient to recovery, the simple venous detaining needle of structure.
For achieving the above object, this utility model provides following technical scheme: a kind of venous detaining needle, include syringe needle and be sheathed on the needle tubing outside syringe needle, axial one end of syringe needle is skewed fluid output port, the other end is provided with the needle holder with syringe needle socket connection, be provided with outside needle tubing can with the transfusion tube joint of syringe needle conducting and holding plate, it is characterized in that: described needle holder is fixedly connected with syringe needle, described needle holder is provided with towards one end of needle tubing the extension block extended in needle tubing, the outer peripheral face of extension block is provided with guide rail, the inwall of needle tubing is provided with the guide groove with extension block upper rail adaptation, the opening part that this guide groove is positioned at needle tubing is provided with the spacing ring removably connected with needle tubing.
Adopt technique scheme, syringe needle and needle holder are in being fixedly connected with, and needle holder is coordinated in guide rail guide groove with between needle tubing by the extension block it extended in needle tubing, when venous detaining needle is without the need to using, needle holder can be pulled, the outfan of syringe needle surface thereof shape (i.e. needle point) is impelled to be in needle tubing, thus avoid the outfan of syringe needle to cause accidental injury to medical personnel or reclaimer operation personnel, avoid infection, during as used, then needle holder can be promoted, the outfan of syringe needle is impelled to appear with outside needle tubing, not only structure is simple, and use safety, be convenient to reclaim.
This utility model is set to further: the opening part that needle tubing is positioned at syringe needle output one end is provided with and is articulated and connected with needle tubing and can the flame-arrester vent plug of this opening of shutoff, and flame-arrester vent plug is provided with elastic sponge body.
Adopt technique scheme; the setting of flame-arrester vent plug can further ensure venous detaining needle when without the need to using Absorbable organic halogens be in needle tubing; can not cause accidental injury, on flame-arrester vent plug, the setting of elastic sponge body is then for implementing protection to syringe needle, prevents the outfan blocking or bending of syringe needle.
This utility model is further set to: needle holder offering with syringe needle is the spliced eye of interference fit, and syringe needle is fixedly connected with needle holder by this spliced eye, and spacing ring and needle tubing are screw thread rotation.
Adopt technique scheme, it is simple that structure is set like this, easy accessibility.
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
A kind of venous detaining needle as shown in Figure 1, include syringe needle 1 and be sheathed on the needle tubing 2 outside syringe needle 1, axial one end of syringe needle 1 is skewed fluid output port 11, the other end is provided with the needle holder 3 with syringe needle 1 socket connection, be provided with outside needle tubing 2 can with the transfusion tube joint 21 of syringe needle 1 conducting and holding plate 22, needle holder 3 is fixedly connected with syringe needle 1, needle holder 3 is provided with towards one end of needle tubing 2 extension block 31 extended in needle tubing 2, the outer peripheral face of extension block 31 is provided with guide rail 311, the inwall of needle tubing 2 is provided with the guide groove 23 with extension block 31 upper rail 311 adaptation, the opening part that this guide groove 23 is positioned at needle tubing 2 is provided with the spacing ring 24 removably connected with needle tubing 2.In such scheme, syringe needle 1 and needle holder 3 are in being fixedly connected with, and needle holder 3 is coordinated in guide rail guide groove with between needle tubing 2 by the extension block 31 it extended in needle tubing 2, when venous detaining needle is without the need to using, needle holder 3 can be pulled, the outfan 11 (i.e. needle point) of syringe needle 2 surface thereof shape is impelled to be in needle tubing 2, thus avoid outfan 11 couples of medical personnel of syringe needle 2 or reclaimer operation personnel to cause accidental injury, avoid infection, during as used, then can promote needle holder 3, the outfan 11 of syringe needle 1 is impelled to appear with outside needle tubing 2, not only structure is simple, and use safety, be convenient to reclaim.
In this utility model embodiment, when without the need to using, medical personnel are caused to further avoid syringe needle 1 and accidentally injure and infect, the opening part that needle tubing 2 is positioned at one end, syringe needle 1 outfan 11 place is provided with and is articulated and connected with needle tubing 2 and can the flame-arrester vent plug 4 of this opening of shutoff, and flame-arrester vent plug 4 is provided with elastic sponge body 41.The setting of this place's elastic sponge body 41 is then for implementing protection to syringe needle 1; prevent the outfan 11 of syringe needle 1 from blocking or bend; it should be noted that; flame-arrester vent plug 4 also can directly and needle tubing 2 socket connection; also be feasible; after just arranging like this, flame-arrester vent plug 4 is easily lost, so this utility model is preferably front plant set-up mode.
For making the connection between needle holder 3 and syringe needle 1 more compact, needle holder 3 offers and the spliced eye 32 of syringe needle 1 in interference fit, syringe needle 1 is fixedly connected with needle holder 3 by this spliced eye 32; Certainly, also implement clamping by shackle member between syringe needle 1 and needle holder 3, or welding, be also feasible.Spacing ring 24 on needle tubing 2 is screw thread rotation with needle tubing 2, certainly, and also can clamping.
