Abstract

The invention discloses a kind of manufacture method with medical tracheal intubation (conduit) of X-ray isolychn, the feature of method is to make raw material with polrvinyl chloride, wherein sub-fraction is mixed with the X-ray luminous agent, and raw material is a continuous body by a bicavity mould final molding.With the intubate that this method makes, the thin footpath of wall is big, the ventilation foot, be convenient to do scale or labelling, and the X-ray isolychn is arranged, so but on the fluorescent screen situation and the degree of depth at clear view intubate position, and price is low, is suitable for the domestic disposable medical article of doing.

Description

A kind of manufacture method of tracheal intubation

The invention belongs to a kind of medical tracheal intubation (conduit), particularly have a manufacture method of the intubate of X-ray isolychn.

The at present domestic medical trachea (conduit) that generally uses is a silicone rubber tube, its thickness of pipe wall, internal diameter are little, so aeration resistance is big, particularly there are not long measure or scale mark on the tube wall, there is not the X-ray isolychn yet, this causes the operator to be difficult for grasping the situation at insertion depth and intubate position, so result of use is not good.External existing intubate of new generation, the thin footpath of wall is big, and the ventilation foot has scale mark and X-ray isolychn on the tube wall, and result of use is good, but price is rather stiff also can't be applied as disposable product is domestic.

The manufacture method that the purpose of this invention is to provide a kind of medical tracheal intubation, the thin footpath of its product wall is big, the ventilation foot, be convenient to do scale or labelling, and the X-ray isolychn is arranged, so that observe the position situation and the degree of depth of intubate, and manufacture method is simple, cost is low, is suitable for the domestic disposable medical article of doing.

The present invention is achieved in that a kind of manufacture method with tracheal intubation of X-ray isolychn, it is characterized in that making raw material with the polyvinyl chloride of medical grade, raw material is told sub-fraction with X-ray luminous agent uniform mixing, then the raw material that contains the X-ray luminous agent and all the other raw materials of not containing the X-ray luminous agent respectively by two tracts of a bicavity mould of plastic production machinery input, be a successive body by this mould final molding.

Such scheme adopts polyvinyl chloride to make raw material, compared with making raw material with silicone rubber, the body rigidity is better, so tube wall can be done thinlyyer, caliber is bigger, the ventilation foot, and the pipe outer wall also is easy to print this degree and labelling, particularly press such scheme, those raw materials that contain the X-ray luminous agent become an X-ray isolychn at the body mo(u)ld top half, and described luminous agent can be a barium sulfate etc., and isolychn can be luminous under the X-ray irradiation, make the situation and the degree of depth at intubate position clearly visible on fluorescent screen, this can reach the good medical treatment result of use, and because manufacture method is simpler, raw material is more common, so cost is lower, be convenient to apply at home.

By the following examples the present invention is done to describe more specifically.

Embodiment: a kind of manufacture method with tracheal intubation of X-ray isolychn, be to make raw material with the medical grade polyvinyl chloride, raw material is told sub-fraction with an amount of barium sulfate uniform mixing, can adopt the heating hybrid mode during mixing, after making the isolychn molding, become visible lines, mixed process has also added coloring agent (as cerulean), then the raw material that contains barium sulfate and the raw material of barium sulfate-containing not, being input into two tracts of a bicavity mould respectively by two plastic extruders (or injector), is a successive body by this mould final molding.

After the above-mentioned body molding, can be cut into all size length as requested, print on the outer tube wall and insert dark labelling, removal is as the sharp edge of socket one end, and load onto the standard interface that can cooperate with various medical apparatus and instruments (as respiratory organ, anesthetic machine etc.), just become the product of tracheal intubation (conduit).

Claims

1, a kind of manufacture method with tracheal intubation of X-ray isolychn, be characterised in that with the polyvinyl chloride of medical grade and make raw material, raw material is told sub-fraction with X-ray luminous agent uniform mixing, then the raw material that contains the X-ray luminous agent and all the other raw materials of not containing the X-ray luminous agent respectively by two tracts of a bicavity mould of plastic production machinery input, be a successive body by this mould final molding.

2, by the described method of claim 1, it is characterized in that this X-ray luminous agent is a barium sulfate.

3, by claim 1 or 2 described methods, it is characterized in that the mixed process of this fraction raw material, also added coloring agent with the X-ray luminous agent.
