Description

Corrosion resistant anesthesia catheter

[ technical field ] A method for producing a semiconductor device

The application relates to the technical field of medical equipment, in particular to an anti-corrosion anesthetic tube.

[ background of the invention ]

Anesthesia catheters are a clinical necessity for performing anesthesia procedures, and are frequently used, particularly, in local anesthesia. Usually, one end of an anesthesia catheter is inserted into a human body by virtue of a puncture needle, the other end of the anesthesia catheter is led out of the human body and is connected with a corresponding catheter connector, and anesthetic is input into the anesthesia catheter through the catheter connector.

In order to fixedly support the anesthesia catheter, a steel wire spring is usually added in the anesthesia catheter, and the phenomena of blockage and uneven flow rate in the anesthesia catheter caused by the fact that the anesthesia catheter is folded and collapsed are effectively avoided. However, when the anesthetic tube is taken out from the human body, the human tissue generally coated on the outer wall of the anesthetic tube can damage the outer plastic skin of the anesthetic tube, so that the liquid medicine in the anesthetic tube reacts with the steel wire spring to corrode the spring, the spring is exposed and harmful effects are caused to the human body, and because the elastic coefficients and the ductility of the plastic tube and the spring are different, when the anesthetic tube is taken out, the diameter of the plastic tube can become thinner and smaller due to stretching, the deformation generated by the spring is smaller relative to the plastic tube, the spring can be adhered to the inner wall of the anesthetic tube, the surface of the anesthetic tube is uneven, the human tissue is easily scratched when the anesthetic tube is taken out, and. Therefore, there is a need for a new type of anesthetic catheter.

[ summary of the invention ]

In response to the deficiencies of the prior art, the present application provides a corrosion resistant anesthesia catheter.

The technical scheme adopted for solving the technical problem is as follows:

the anti-corrosion anesthetic tube comprises a hollow tube body, wherein a hollow plastic elastic support body used for supporting the tube body is arranged in the tube body.

The corrosion-resistant anesthetic tube as described above, wherein the plastic elastic support body has a spiral structure.

The corrosion-resistant anesthetic tube as described above, wherein the plastic elastic support is a plastic spring.

The corrosion-resistant anesthetic tube as described above, wherein the plastic elastic support is a net structure.

The corrosion-resistant anesthetic tube comprises a tube body, a plastic elastic support body and a plurality of elastic connecting pieces.

The anti-corrosion anesthetic tube, the tube body and the plastic elastic support body are made of PVC or TPU.

The anti-corrosion anesthetic tube is characterized in that the front end of the tube body is provided with a hydrophilic coating.

Compared with the prior art, the anesthesia catheter of the application has the beneficial effects that the plastic spring is arranged in the plastic catheter, so that the anesthesia catheter has good corrosion resistance, meanwhile, the spring and the catheter are made of the same material, the compatibility is good, the elastic coefficient and the ductility are the same, so that when the anesthesia catheter is taken out, the spring cannot be adhered to the inner wall of the catheter and can deform along with the deformation of the catheter, the surface of the catheter is smooth, and when the anesthesia catheter is taken out from a human body, the infection is caused by scratching human tissues.

[ detailed description ] embodiments

The present application will be further described with reference to the following drawings and specific embodiments.

Referring to fig. 1, an anti-corrosion anesthetic tube includes a hollow tube body 1, and a hollow plastic elastic support body 2 for supporting the tube body is disposed in the tube body, and the elastic support body is made of plastic, so as to enhance the corrosion of the anesthetic tube. In this embodiment, the tube body 1 and the plastic elastic support body 2 are made of PVC or TPU, so that the anesthetic tube has good elasticity and flexibility. Specifically, please refer to fig. 2, in this embodiment, the plastic elastic support 2 is a spiral plastic spring integrally formed on the inner wall of the tube body by co-extrusion technology, so that the anesthetic tube has good overall flexibility, and meanwhile, the spring and the tube are made of the same material and have good compatibility, and the same elastic coefficient and ductility ensure that the spring does not stick to the inner wall of the tube and can deform along with the deformation of the tube when the anesthetic tube is taken out, and the surface of the tube is smooth, so that the tube can not scratch the tissue of the human body to cause infection when taken out from the human body.

Preferably, the front end of the tube body 1 is provided with a hydrophilic coating, so that the tube is easy to pull out, and the risks of damaging or puncturing blood vessels, puncturing hard spinal cords and damaging spinal nerves in the tube placing process can be reduced.

In addition, referring to fig. 3, as another embodiment of the present application, the plastic elastic support body 2 can also be configured as a net-shaped support structure, which has strong tensile resistance, and effectively avoids the phenomena of blockage and uneven flow rate in the anesthesia catheter caused by the folding and collapsing of the anesthesia catheter.

The utility model provides an anesthesia catheter, the steel wire spring in the pipe is replaced by the plastic spring, makes anesthesia catheter have good corrosion resistance, and spring and pipe are made by same material simultaneously, and the compatibility is better, and coefficient of elasticity and ductility are the same makes when taking out anesthesia catheter, and the spring can not glue the inner wall at the pipe, can deform along with the deformation of pipe on the contrary, and the pipe surface is smooth, can not scratch human tissue and cause the infection when taking out from the human body.

The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not intended to limit the scope of the present application, which is within the scope of the present application, except that the same or similar principles and basic structures as the present application may be used.
