Abstract
One through internal jugular vein puncture central venous catheter external end anchors, belongs to technical field of medical instruments around ear formula.Arc support connects circular support, and be connected with conduit retainers after arc support is connected with circular support, conduit retainers is: train wheel bridge is connected by snap close with lower plate, and conduit is placed between train wheel bridge and lower plate.The utility model has the advantages that and be applicable to be fixed on ear week by through internal jugular vein puncture central venous catheter outer end, the special shape taking full advantage of auricle fixes.
Description
Technical field
This utility model relate to a kind of around ear formula through internal jugular vein puncture central venous catheter external end anchors, belong to technical field of medical instruments.
Background technology
Along with the develop rapidly of medical science, central vein catheter application is clinically more and more extensive, and indwelling time in human body is also more and more longer, and therefore, in nursing, appropriate A/C, maintenance clearness of catheter, prevention infection are very important links.Finding simple and effective conduit fixing means, is the guarantee that nursing staff improves nursing quality.
Internal jugular vein at present adopts one of maximum central vein catheter approach, because of its body surface symbol relatively obviously, easily puncture, simple to operate, blood flow is sufficient, activity is unrestricted and indwelling time length and the advantage such as easy to use and widely used as blood vessel access by clinical.
Internal jugular vein cannulation has higher risk of infection, is because it secretes district near oropharynx, and fixing more difficult.
In addition, cervical region mobility is large, if patient perspires and easily causes pad pasting and lose stickiness and cause aseptic pad pasting crimping to loosen, more easily causes conduit loose or dislocation.Meanwhile, conventionally external catheter end is directly pasted onto and ear easily causes skin injury and easily comes off, therefore need a kind of effective fixture badly.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides one around ear formula through internal jugular vein puncture central venous catheter external end anchors.
A kind of around ear formula through internal jugular vein puncture central venous catheter external end anchors, arc support connects circular support, circular support and conduit retainers are integrated, circular support can embed in auditory meatus, conduit retainers is: train wheel bridge is connected by snap close with lower plate, and conduit is placed between train wheel bridge and lower plate.
The long 5.3cm of arc support, wide 2.5cm, there is sponge wrapping outside, and arc support front end is not closed buckle by one and is connected with circular support, and the angle of arc support and circular support can adjust; The diameter 1.4cm of circular support; There is conduit retainers in the front of circular support, the long 2cm of conduit retainers, wide 1cm; There is rubber layer conduit retainers inside.
The utility model has the advantages that and be applicable to be fixed on ear week by through internal jugular vein puncture central venous catheter outer end, the special shape taking full advantage of auricle fixes, and has following innovative point:
1, fixation, difficult drop-off; Utilize mechanics principle, play pinna shape advantage, the snap close of holder greatly reduces conduit and to come off risk, avoids tradition rubberized fabric adhere conduit and holds caducous phenomenon;
2, nurse operation is facilitated; Pipe is drawn along auricle, ensure that external catheter end is exposed to patient's head side, facilitates nurse's administration at any time and catheter maintenance, comparatively other fixing meanss (as being oppositely fixed on clavicle side), and patient's jacket can normal setting fastening and do not need repeatedly to take off solution.
3, use comfortable, handsome in appearance; The holder of sponge material uses comfortable, avoids tradition adhesive plaster and conduit is directly sticked at patient's auricle, probably cause skin injury, also have impact on the attractive in appearance of patient simultaneously.
4, the material of conduit retainers is transparent material, convenient observation conduit situation.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, more completely can understand this utility model better and easily learn wherein many adjoint advantages, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining this utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is conduit retainers 3 structural representation of the present utility model.
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Detailed description of the invention
Obviously, those skilled in the art belong to protection domain of the present utility model based on the many modifications and variations that aim of the present utility model is done.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of around ear formula through internal jugular vein puncture central venous catheter external end anchors, arc support 1 connects circular support 2, be connected with conduit retainers 3 after arc support 1 is connected with circular support 2, conduit retainers 3 is: train wheel bridge 6 is connected by snap close 5 with lower plate 7, and conduit is placed between train wheel bridge 6 and lower plate 7.
Embodiment 2: as shown in Figure 1 and Figure 2, one is around ear formula through internal jugular vein puncture central venous catheter external end anchors, and entirety is divided into three parts,
Part I is the arc support 1 being surrounded on auricle rear, be about 5.3cm, wide about 2.5cm, internal material is plastics, there is sponge wrapping outside, plays comfortable fixing effect, and support front end has a miniature circular not close buckle, for being connected with Part II by arc support, adjust the angle of arc support and circular support by rotating buckle;
Part II is the circular support 2 (diameter 1.4cm) of external auditory meatus entrance, shape is equivalent to the receiver of earphone, inside is plastics, outside is sponge material, and for holder 3 being fixed on external auditory meatus outlet, circular support 2 is as a whole with conduit retainers 3.Circular support 2 and arc support 1 are formed and ensure that holder is stably fixed on difficult drop-off on ear with joint efforts;
Part III is that the front of circular support 2 has conduit retainers 3, and conduit retainers 3 is that fixed center vein outer end conduit is used, and is about 2cm, wide about 1cm.
Open it central vein outer end conduit is put into wherein, then closure catheter for closing holder 3, external catheter end tightly can be fixed in conduit retainers 3 and can not to come off.
Conduit retainers 3 inside is quality of rubber materials, prevents conduit pressurized, and the conduit that can adapt to different thicknesses embeds, and outside is plastic material, and centre has snap close conduit retainers 3 can be pinned.
Circular support 2 is integral with conduit retainers 3, and junction is not rotatable.Arc support 1 can adjust with the angle of circular support 2.
As mentioned above, embodiment of the present utility model is explained, but as long as do not depart from inventive point of the present utility model in fact and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation is also all included within protection domain of the present utility model.
