Multi-pipe-diameter medical catheter is fixing to be pasted
Technical field
The present invention relates to the fixing of medical catheter, particularly, relate to the fixing subsides of a kind of multi-pipe-diameter medical catheter.
Background technology
Medical catheter, as the pipeline connected inside and outside human body, is widely used in medical field, as drainage tube, tube for transfusion, blood transfusion tube etc.And no matter which kind of medical catheter, it in use all needs effectively to fix it, prevents the displacement of medical catheter, loosens or even come off, otherwise conditions of patients can be caused to increase the weight of or delay state of an illness rehabilitation.Also occurred that some have the fixing subsides of certain fixed function to medical catheter in the market, but these fixing subsides all can only be applicable to the conduit of specific standard size usually, the conduit of different size size needs the fixing subsides adopting corresponding different size, very inconvenient.
Summary of the invention
Technical problem to be solved by this invention is to provide the fixing subsides of multi-pipe-diameter medical catheter.
The present invention's adopted technical scheme that solves the problem is:
Multi-pipe-diameter medical catheter is fixing to be pasted, comprise adhered layer, fixed layer and fixed block, described fixed block is fixedly installed on described fixed layer, described adhered layer is arranged at the side of described fixed layer relative to described fixed block, one end of the contiguous described fixed layer of described fixed block offers the fixing hole with an opening, the contiguous described fixed layer of opening of described fixing hole is arranged, medical catheter is fixed in the fixing subsides of described medical catheter through described fixing hole, the top of described fixed block is provided with the through hole be connected with described fixing hole, a fixed axis is provided with in described through hole, the axis of described fixed axis parallels with the axis of described fixing hole, one regulating block is sheathed on described fixed axis in relative rotation, and described regulating block offers the through hole passed for described fixed axis, described regulating block comprises opposing parallel both ends of the surface and four cambered surfaces, described through hole runs through described both ends of the surface, distance between described through hole and described four cambered surfaces is unequal.Thus, by rotating described regulating block, making the fixed space between described regulating block from described fixed layer different, thus the medical catheter of different size size can be fixed.
Further, described four cambered surfaces are respectively the first cambered surface, the second cambered surface, the 3rd cambered surface and the 4th cambered surface, and described four cambered surfaces are arranged in order from small to large according to the distance between described through hole and are respectively: the first cambered surface, the second cambered surface, the 3rd cambered surface, the 4th cambered surface.
To sum up, the invention has the beneficial effects as follows: medical catheter of the present invention is fixing to be pasted, by rotating medical catheter fixing regulating described regulating block to realize for different size size.

Labelling and corresponding parts title in accompanying drawing: medical catheter fixes subsides 100, adhered layer 10, fixed layer 20, fixed block 30, fixing hole 31, through hole 32, regulating block 33, through hole 335, end face 331, second cambered surface 332, the 3rd cambered surface 333.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1
Refer to Fig. 1-2, the medical catheter shown in present pre-ferred embodiments fixes subsides 100, comprises adhered layer 10, fixed layer 20 and fixed block 30.
Described fixed block 30 is fixedly installed on described fixed layer 20, and described adhered layer 10 is arranged at the side of described fixed layer 20 relative to described fixed block 30.
One end of the contiguous described fixed layer 20 of described fixed block 30 offers the fixing hole 31 with an opening (figure does not mark), and the contiguous described fixed layer 20 of opening of described fixing hole 31 is arranged.Medical catheter is fixed on described medical catheter through described fixing hole 31 to be fixed in subsides 100.For being applicable to the medical catheter of plurality of specifications size, the top of described fixed block 30 is provided with the through hole 32 be connected with described fixing hole 31, be provided with a fixed axis (not shown) in described through hole 32, the axis of described fixed axis parallels with the axis of described fixing hole 31.One regulating block 33 is sheathed on described fixed axis in relative rotation, be appreciated that, described regulating block 33 offers the through hole 335 passed for described fixed axis, described regulating block 33 comprises opposing parallel both ends of the surface 331 and four cambered surfaces, be respectively the first cambered surface (not shown), the second cambered surface 332, the 3rd cambered surface 333 and the 4th cambered surface (not shown), described through hole 335 runs through described both ends of the surface 331.Described through hole 335 is unequal with the distance of described four cambered surfaces, thus, by rotating described regulating block 33, making the fixed space between described regulating block 33 from described fixed layer 20 different, thus can fix the medical catheter of different size size.In the present embodiment, described four cambered surfaces are arranged in order from small to large according to the distance between described through hole 335 and are respectively: the first cambered surface, the second cambered surface 332, the 3rd cambered surface 333, the 4th cambered surface.
To sum up, medical catheter of the present invention fixes subsides 100, by rotating medical catheter fixing regulating described regulating block 33 to realize for different size size.
As mentioned above, the present invention can be realized preferably.
