Abstract
The present invention discloses a manufacturing technology of a tracheal cannula, which belongs to a cannula for trachea. The purpose of the present invention is to provide a manufacturing technology of a tracheal cannula. The present invention has the technical scheme that a manufacturing technology of a tracheal cannula is characterized in that the process comprises: (1), a metal spring is sheathed on a round rod, the diameter of which is identical with the internal diameter of the tracheal cannula; (2), the round bar which is sheathed with the metal spring is placed in a preheating furnace and preheated for 3 to 5 minutes under the temperature of 280 to 330DEG. C; (3), the well preheated round bar which is sheathed with the metal spring is soaked in a PVC liquid groove for 1 to 5 minutes and taken out; (4), the round bar which is dipped with PVC liquid and sheathed with the metal spring is placed in a heating furnace and heated for 2 to 5 minutes, and the furnace temperature is 270 to 320DEG. C; (5), after heated, the round bar which is sheathed with the metal spring is taken out from the furnace and cooled to the indoor temperature, the excessive irregular end heads on both ends are cut off, and a tracheal cannula final product is formed after disengaged from the round bar. The present invention is used for manufacturing tracheal cannulas.
Description
Technical field:
The present invention relates to a kind of tracheae intubate, particularly a kind of process for manufacturing tracheal cannula.
Background technology:
Trachea cannula is used for transmitting gas and inhalation anesthetic agent to lung, and this intubate is a plastic tube, and its production technology is plastic extruder production, and this plastic cannula is softer, and the pipe parts during use outside the patient body gives a discount and distortion easily, causes ventilation not smooth.For head it off, designed the intubate that tube wall is embedded with metal spring, yet the intubate of this embedded spring can not use original extrusion molding technology.
Summary of the invention:
The technical issues that need to address of the present invention provide a kind of process for manufacturing tracheal cannula, and this technology does not need special equipment, and cost is low.A kind of process for manufacturing tracheal cannula, it is characterized in that carrying out according to following process sequence: (1) is enclosed within metal spring on the diameter pole identical with the trachea cannula internal diameter, (2) pole that will be with metal spring places in the preheating furnace, at 280-330 ℃ of following preheating 3-5 minute, (3) pole of the cover metal spring that preheating is good was immersed in the polyvinyl chloride liquid tank after 1-5 minute, take out pole, (4) the above-mentioned pole that is with metal spring of hanging the liquid polyvinyl chloride that dips in is placed in the heating furnace, furnace temperature is 270-320 ℃, heated 2-5 minute, (5) the cover metal spring pole after will heating takes out cool to room temperature from stove, cut away unnecessary irregular termination, two, and separate from pole, the trachea cannula finished product.It is few that technology of the present invention has an equipment investment, the simple remarkable advantage of technology.
The specific embodiment:
The present invention has following operation:
(1) metal spring is enclosed within is placed on preheating in the preheating furnace on the mould, furnace temperature is 280-330 ℃, preheating 3-5 minute.Shaping mould is a pole, and its diameter is identical with the internal diameter of the trachea cannula of formed thereby.Spring is made of stainless steel wire, and steel wire diameter is generally can satisfy the needs that anti-intubate gives a discount and twists about 0.2mm.
(2) mould after the preheating is dipped in the polyvinyl chloride liquid tank after 1-5 minute, takes out mould.If when hanging with excessive liquid paste, but the percussion vibration mould is removed excessive liquid and is stuck with paste.
(3) will dip in the mould of hanging polyvinyl chloride liquid and place heating furnace, furnace temperature is 270-320 ℃, heats 2-5 minute.
(4) mould after will heating takes out with after the blower fan blast-cold or naturally cooling to room temperature, excises unnecessary termination, goods two, and deviates from goods from pole, promptly obtains desired trachea cannula.
Claims (1)
1. process for manufacturing tracheal cannula, it is characterized in that carrying out according to following process sequence: (1) is enclosed within metal spring on the diameter pole identical with the trachea cannula internal diameter, (2) pole that will be with metal spring places in the preheating furnace, at 280-330 ℃ of following preheating 3-5 minute, (3) pole of the cover metal spring that preheating is good was immersed in the polyvinyl chloride liquid tank after 1-5 minute, take out pole, (4) the above-mentioned pole that is with metal spring of hanging the liquid polyvinyl chloride that dips in is placed in the heating furnace, furnace temperature is 270-320 ℃, heated 2-5 minute, (5) the cover metal spring pole after will heating takes out cool to room temperature from stove, cut away unnecessary irregular termination, two, and separate from pole, the trachea cannula finished product.
