Description
Technical field
The invention belongs to fitting of medical apparatus field, be specifically related to a kind of sound guide tube, sound guide tube preparation method and mould.
Background technology
As shown in Figure 1, existing stethoscope adopts one whole sound guide tube usually, and existing sound conducting tube of stethoscope is PVC leaching moulds integrated, thus causes sound guide tube pipe thickness uneven.
The processing technique of PVC sound guide tube is: first the set of molds of having decomposed installed, then the mould assembled is heated, again the mould after heating is immersed in PVC material, baking box hot setting is put into after mould absorption PVC molding, subsequently the demoulding of curing molding PVC sound guide tube is decomposed, finally the pvc pipe of molding is sheared.Visible, 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, the thickness difference of the PVC material causing mould different parts adsorb.Secondly, pipe thickness and the mould of PVC sound guide tube be trapped in PVC expect in time length relevant, and workman cannot accomplish definitely unanimously to the control that the time is moulded in mould leaching, if deviation 1s or 2s also can cause the wall thickness difference of sound guide tube.Therefore the concordance of pvc pipe is poor, every root pipe is all not identical, even if the wall thickness of same pipe is also uneven, thus causes the ability of anti-ambient noise inconsistent, thus has a strong impact on outward appearance and listens sound quality.
In addition, due to the linear change of pvc pipe temperature influence, the rate of change of pvc pipe temperature influence is 30%-40%, along with temperature reduce pipe can become very hard.
Moreover because needs decompose the demoulding in PVC sound guide tube production process, therefore the workload of workman is large, and production efficiency is very low, and within one day, a direct labor can only produce 100-200 bar PVC sound guide tube.
As shown in Figure 2, also there is Combined type sound conducting tube (application number is CN201120294632.5) in existing stethoscope, comprise tee T leading note section and straight tube leading note section, also comprise three-way connector, tee T leading note section is connected by three-way connector with straight tube leading note section.
But this Combined type sound conducting tube needs three-way connector, the processing technique of Combined type sound conducting tube just adds the step relating to three-way connector: get out the three-way connector that both ends are provided with internal thread hole, one end is provided with externally threaded die mandrel, the internal thread hole of three-way connector coordinates fixing with the external screw thread of die mandrel, the three-way connector be fixedly connected with and die mandrel are suspended in triplet type gel-injection mould in the groove reserved, the outside of triplet type gel-injection mould after the other end of three-way connector is placed in and closes, three-way connector one end of the latter half of Combined type sound conducting tube being placed on the first half of Combined type sound conducting tube does not wrap one end of silica gel.
The step that the preparation method of this Combined type sound conducting tube relates to three-way connector is many, and this preparation method is made complicated, the use of three-way connector also causes production cost high.
Also there is diagnostic tube (application number is CN201210080016.9) in existing stethoscope, comprise the tube body be made up of silica gel material, tube body comprises the upper end for being connected with receiver and the bottom for being connected with stethoscope, and tube body is one-body molded through the thermosetting of injection-molding technique.This integrated diagnostic tube needs to use mould in solid hot one-body molded process when making, if the upper end of mould and the internal diameter size of bottom are made into the same and sebific duct length is long, inherently cause the quality of the product produced and result of use bad; If the size of the upper end of mould and bottom and inner core is inconsistent, entire length is long simultaneously will cause the cost of mfg. moulding die significantly to increase and production stability variation, and yield rate step-down, economic benefit declines.
