Description
Technical field
The invention belongs to Medical anesthetic fixture technology field, and in particular to a kind of spiral wire of flexible antisitic defect is reinforced
Anesthetic tube and preparation method thereof.
Background technology
Extradural nerve block of the prior art is a kind of anesthesia of wide clinical application, with it is simple to operate,
Be easily managed in low cost, art, it is postoperative the advantages of be easy to Epidural analgesia, the critical piece that this anesthesia is used is
Anesthetic tube.Traditional anesthetic tube is formed by transparent conduit and pipe joint grafting, because conduit is plastic material, during operation
Easily it is crushed or is converted into dead angle, cause path to be closed, anaesthetic effect is poor;When the hardness of conduit material is high, conduit is easy to
Human body is inserted, but the easy tissue blood vessel that stabs of flexibility ratio difference, nerve even break endorchis, and there is the phenomenon damaged particularly in blood vessel
Prominent, security is poor;When the hardness of conduit material is low, flexibility ratio is high, but conduit is not easy to insert spinal epidural cavity, also,
It is easily bent after inserting and is even knotted, cause conduit to take out, operation is wasted time and energy;What segmental epidural catheter was finally inserted
Epidural intraluminal tissue is soft and be rich in nerve, conventional catheters insert after easy compressing spinal epidural cavity nerve, cause patient
Comfort level it is poor.
The spiral wire of the wire reinforced conduit of conventional helical is directly contacted with liquid, because spiral wire winding process is needed
Mineral oil lubrication is added, needs to carry out spiral wire crack cleaning, the drying course of complexity before production conduit, and be difficult to clean,
Easy laying dust pollution between spiral wire and sleeve pipe in production process, finally enters human body spinal cavity and produces many sequelae with liquid.
Spiral wire is directly contacted with liquid, its rough surface, is unfavorable for liquid medicine flow, and flow reduces, and liquid is pressed from both sides into spiral wire
In seam, residual quantity is not easy to control.

As shown in figure 1, the present invention provides a kind of spiral wire reinforced anesthetic conduit of flexible antisitic defect, including conduit and
Pipe joint 1, the conduit includes body 2 and tube head 3, the one end of the body 2 and the socket connection of the pipe joint 1, another
The end connection tube head 3;The hardness of the tube head 3 is gradually hardened to the direction of the body 2 from its front end by soft;The body 2
The spiral wire 5 with strengthening inside is provided with, it is provided with some medicine outlet holes 4 with the end that the tube head 3 is connected.The length of the tube head 2
Degree is not more than 1cm, it is ensured that the overall hardness of conduit, it is to avoid the bending even generation of knotting phenomenon after inserting.
In another embodiment, the tube head 2 is the solid construction of soft macromolecular material.Wherein, soft macromolecular material is selected from
One kind in PA, PEBAX, polyurethane, thermoplastic elastomer (TPE).
In another embodiment, the conduit is longitudinally provided with the impermeable developing line of X-ray.The conduit is provided with some apart from mark line
6.It is described to be marked since the one end of the conduit away from the pipe joint apart from mark line 6, every described in 50mm after 100mm
Apart from the overstriking of mark line 6 mark.Marked for ease of reading, marked using two-wire at 100mm, three wire tags are used at 150mm, with
This analogizes.
As shown in Fig. 2 in another embodiment, the body is cone, conical structure energy with the tube head junction
Enough increase the contact area of body and tube head, increase firm welding degree.
As shown in figure 3, in another embodiment, the spiral wire from the tube head to pipe joint direction pitch by
Taper into greatly, it is possible to achieve anesthetic tube is gradually softened forward by rear end, prevent from damaging endorchis.
The preparation method of the spiral wire reinforced anesthetic conduit of above-mentioned flexible antisitic defect(By taking the conduit of external diameter 1mm as an example
Explanation):
As shown in figure 4, first using precise micro-extrusion machine, extrude(Polyurethane, PA, PEBAX)The conduit internal layer of thermoplastic, leads
Inner tube layer external diameter about 0.5mm(Internal diameter about 0.4mm), the internal-and external diameter of spiral wire coordinated with 1.0mm external diameters product is about
0.55mm(External diameter about 0.7mm), conduit internal layer insertion spiral wire inner chamber.By ready high temperature resistant Inflatable elastic rubber tube
In insertion conduit internal layer cavity, one end sealing, the other end connects the inflation inlet of aerating device(The gas injection port structure and tyre inflating
The one-way cock of mouth is similar).Elastic rubber pipe in addition to elastic rubber pipe two ends, conduit internal layer and spiral wire are placed in close
Close in device, be first heated to conduit internal layer and start to soften, then vacuumize, make conduit inner layer expansion, its outer surface enters spiral
In steel wire crack, inflated in elastic rubber pipe, expand it, drive the expansion of conduit internal layer, travel further into spiral wire folder
In seam, elastic rubber pipe ensures that conduit internal layer inner surface is smooth, during stabilization internal diameter about 0.5mm, stops heating, makes in conduit internal layer
Footpath is set in 0.5mm, stops heating, and after the solidification of conduit internal layer, elastic rubber pipe is extracted out after losing heart from conduit internal layer.
Fixed inner diameter and material are goed deep into crack in spiral wire pitch as semi-finished product I, outside this semi-finished product I
One layer of biocompatibility medical material of co-extrusion(Such as polyurethane, PA, PEBAX), as the outer wall of product, realize tube wall inside cladding
Spiral wire.
Method using heating melting closes one end of conduit, cone is then pulled fine as, with prefabricated tube head
Semi-finished product ultrasonic bonding;With puncher liquid aperture is stamped out in conduit head end;Printed with special printing equipment in catheter surface
High scale line, and dried on special drying device, obtain final product the spiral wire reinforced anesthetic conduit of the flexible antisitic defect.
Rational in infrastructure, modern design of the invention, flexible tube head causes that catheter head is flexible, easily inserts, it is not easy to damage
Tissue and endorchis, it is to avoid the appearance of postoperative complication;Simultaneously tubular body be provided with spiral wire, improve its axle stability and
The performance of antitorque knot keeps its pliability simultaneously, it is easy to inserts and takes out, and almost not in epidural space interior circuit and beats
The risk of knot, path is smooth during use, and anaesthetic effect is good;To the compressing of spinal epidural cavity nerve after preventing from inserting, peace
Quan Xinggao, comfort level are good.Spiral wire is in the layout of inside anesthetic tube tube wall, spiral wire not with liquid directly contact, crack
The mineral oil of middle residual does not influence liquid, and tube chamber inner surface is smooth medical high polymer, does not influence catheter flow, spiral wire
Locate not residual liquor.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
The personage for knowing this technology all can carry out modifications and changes under without prejudice to spirit and scope of the invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
Into all equivalent modifications or change, should be covered by claim of the invention.
