Abstract
The utility model more particularly relates to a medical silicone rubber conduit with an imbedded guidewire, pertaining to the medical apparatus and instrument field. The utility model is characterized in that: the inside of the silicone rubber conduit is axially embedded with at least one non-elastic guidewire, and the guidewire is made from medical plastic or metal. The silicone rubber conduit can be a one-cavity conduit, a double-cavity conduit, a triple-cavity conduit or a multi-cavity conduit, or any other silicone rubber conduit. The beneficial effects of the utility model are: the conduit is intensified and supported, so that the insert operation in human organs can be easier; the conduit imbedded with the guidewire loses the longitudinal stretching performance, thereby leading the conduit not to generate longitudinal stretching deformation in the process of insertion and extracting and the operation to be easier and safer; since the material of the silicone rubber is not changed, the other performances, particularly flexibility and handfeel, of the silicone rubber are not influenced.
Description
Technical field
This utility model belongs to medical instruments field.Be particularly related to a kind of medical silastic vessel of embeded guidewire.
Background technology
The medical silastic vessel that is widely used in clinical each section has characteristics such as good biocompatibility, ageing-resistant, stable performance, and the clinical use through decades proves a kind of safe and reliable medical material.But often there is the defective of inserting and extracting difficulty in silicon catheter in clinical use, the reason of its generation is that silicon catheter has that tensile property is good, body is especially than characteristics such as capillary base soft pliable songs, these characteristics make silicon catheter can occur bending and deformation when inserting, and when extracting, especially conduit be used for that implant into body uses as catheter, drainage tube, two-chamber pressure-measuring pipe etc., the stretcher strain phenomenon can take place.
At present, be solution to the problems described above, the one, the composition of raw materials of change silicone rubber improves its hardness and reduces its tensile property, but the result of making has reduced the pliability and the feel of silicone rubber often like this, makes conduit itself become fragile, easily break, easily wear out.The 2nd, when inserting conduit, use outside seal wire, though this method is effective, be to use seal wire to make operation become loaded down with trivial details, and after disposed tubes, must extract seal wire, the conduit of extracting behind the seal wire is no longer strong, can make conduit pulling distortion, causes patient's misery simultaneously; On the other hand, caused conduit stretcher strain causes suffering to the patient equally in extracting the process of conduit.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of and can keep that the high resiliency of silicone rubber, pliability are good, the characteristics of good hand touch, simultaneously make medical silastic vessel no longer possess tensile performance in wale-wise again, make it be easy to the medical silastic vessel of the embeded guidewire that inserts and extract.
For achieving the above object, the technical scheme that this utility model adopted is: a kind of medical silastic vessel of embeded guidewire is characterized in that: at silicon catheter tube wall inner shaft to embedding at least one inelastic seal wire.
Above-mentioned seal wire material is various medical plastics or metal.
Above-mentioned silicon catheter is single lumen catheter or double lumen tube, three lumens and multi-lumen tube, also can be other any one silicon catheter.
Any one above-mentioned silicon catheter is that bladder pressure/urethra is pressed two-chamber pressure-measuring pipe or catheter.
Above-mentioned silicon catheter wall thickness hour, its wall portion that embeds seal wire axially has the projection that guarantees uniform thickness.
The beneficial effects of the utility model are: thus silicon catheter itself is strengthened and supported, also make silicon catheter itself lose the performance of longitudinal stretching.
The medical silastic vessel of the embeded guidewire that the utility model proposes has mainly solved following practical problem:
1. embed seal wire and make its permanent fixation at the silicon catheter pars intramuralis, silicon catheter itself is strengthened and supported, when carrying out the insertion of human organ operated, make it easier like this.
2. the silicon catheter behind the embedding seal wire has lost the performance of longitudinal stretching, makes it strong in the process of inserting and extracting, and stretcher strain longitudinally can not take place, thereby make the easier and safety of operation.
3. owing to the silica gel material is not changed itself, therefore can not influence other performance, especially pliability and the feel of silica gel.

Fig. 2 is the sectional view of the medical silastic vessel of double lumen tube embeded guidewire of the present utility model.
Wherein 1, silicon catheter, 2, seal wire, 3 projectioies.
The specific embodiment
Below in conjunction with the specific embodiment and preferred embodiment structure of the present utility model is further specified.
Please refer to accompanying drawing 1-2, a kind of medical silastic vessel of embeded guidewire, by silicon catheter 1 and seal wire 2, wherein silicon catheter pipe shaft 1 is made by medical grade silicon rubber; Seal wire 2 is various medical plastics such as nylon or metal material.Seal wire in the medical silastic vessel directly is covered by in the catheter wall, and embeded guidewire is not only limited to an embedded seal wire, and it can embed two, three, even many seal wires.Described medical silastic vessel is not limited to a certain conduit, and it can be single lumen catheter, double lumen tube, three lumens or multi-lumen tube, also can be other any one silicon catheter, presses two-chamber pressure-measuring pipe, catheter etc. as bladder pressure/urethra.Above-mentioned silicon catheter wall thickness hour, its wall portion that embeds seal wire axially has the projection 3 that guarantees uniform thickness.Embed the silicon catheter behind the seal wire, lost the performance of longitudinal stretching, make it strong in the process of inserting and extracting, and stretcher strain longitudinally can not take place, thereby make the easier and safety of operation.Alleviated patient's misery.
Although the medical silastic vessel of embeded guidewire of the present utility model has been carried out special description with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
