Description
Technical field
This utility model relates to a kind of fitting of medical apparatus, relates in particular to stethoscopic sound guide tube.
Background technology
As shown in Figure 1, existing stethoscope adopts one whole sound guide tube usually, and existing stethoscope sound guide tube be PVC soak mould integrated, thereby cause the sound guide tube pipe thickness inhomogeneous.
The processing technique of PVC sound guide tube is: will decompose good set of molds earlier and install; Then the mould that assembles is heated; Mould after will heating again immerses in the PVC material; Treat to put into the baking box hot setting after the mould absorption PCV molding, subsequently the demoulding of curing molding PVC sound guide tube is decomposed, the pvc pipe shearing to molding at last gets final product.It is thus clear that, in the manufacturing process of PVC sound guide tube, be that the mould after heating is immersed in the material of PVC, because the temperature at each position of mould is different, cause the thickness difference of the PVC material of mould different parts absorption.Secondly, the pipe thickness of PVC sound guide tube is relevant with the time length that mould is trapped in the PVC material, and the workman can't accomplish absolute unanimity to the control that mould soaks the time of moulding, if deviation 1s or 2s also can cause the wall thickness of sound guide tube different.So the concordance of pvc pipe is relatively poor, every pipe is all inequality, even if the wall thickness of same pipe is also inhomogeneous, thereby causes the ability of anti-ambient noise inconsistent, thereby has a strong impact on outward appearance and listen sound quality.
In addition, because the linear variation of pvc pipe temperature influence, the pvc pipe temperature influence is that rate of change is 30%-40%, along with temperature reduces very hard that pipe can become.
Moreover owing to need to decompose the demoulding, so workman's workload is big, production efficiency is very low in the PVC sound guide tube production process, and a direct labor can only produce 100-200 bar PVC sound guide tube in one day.
The utility model content
The purpose of this utility model is to provide a kind of even tube wall, the combination type sound guide tube that temperature influence is little, production efficiency is high.
The purpose of this utility model is achieved in that
A kind of combination type sound guide tube comprises a triplet type sound guide tube and at least one straight barrel type sound guide tube, also is provided with metal connecting piece, and said connector is built in simultaneously in the two sound guide tube tube chambers that are connected and closely cooperates with the wall of the lumen of said tube chamber.
Further; When said sound guide tube was two-chamber sound guide tube or single chamber sound guide tube, said connector was a tubular connection.
Further; Also be provided with the sleeve pipe that is placed in the said sound guide tube that is connected simultaneously, the said sleeve pipe said sound guide tube outer wall of fitting.
Further; Be provided with radially annular groove backward from the mouth of pipe on the said sound guide tube outer wall of link, said sleeve pipe is placed on the said annular groove.
Further; The lumen wall of said straight barrel type sound guide tube one end that is not connected with other sound guide tubes is provided with at least one axial convex shoulder.
A kind of combination type sound guide tube comprises a triplet type sound guide tube and at least one straight barrel type sound guide tube, also is provided with metal connecting piece, and said connector is built in simultaneously in the two sound guide tube tube chambers that are connected and closely cooperates with the wall of the lumen of said tube chamber.When wherein said sound guide tube was two-chamber sound guide tube or single chamber sound guide tube, said connector was a tubular connection.
Further; Be positioned on the lumen wall of said sound guide tube of link and be provided with radially annular groove backward, and said tubular connection places in the said radially annular groove from the mouth of pipe.
Further; Also be provided with the sleeve pipe that is placed in the said sound guide tube that is connected simultaneously, the said sleeve pipe said sound guide tube outer wall of fitting.
Further; Be positioned on the said sound guide tube outer wall of link and be provided with radially annular groove backward from the mouth of pipe, said sleeve pipe is placed on the said annular groove.
Further; The lumen wall of said straight barrel type sound guide tube one end that is not connected with other sound guide tubes is provided with at least one axial convex shoulder.
The shortcoming of prior art: at first the PVC sound guide tube pipe thickness of prior art is inhomogeneous; Be because of after mould is heated, be immersed in the material of PVC,, cause the thickness difference of the PVC material of mould different parts absorption because the temperature at each position of mould is different.Secondly, be because the inhomogeneous sound guide tube temperature influence that causes of sound guide tube pipe thickness is very big, and the production production capacity is low.
The utlity model has following advantage:
1, this utility model sound guide tube wall thickness is even, and anti-ambient noise ability is consistent;
2, this utility model sound guide tube temperature influence is very little, and the temperature influence rate is merely 5-10% (the sebific duct firmness change was the 0.5-1 degree when test environment variations in temperature 10 was spent)
3, this utility model production efficiency significantly improves than prior art;
The data of this utility model and prior art sound guide tube contrast as follows:
