Abstract

An object of the utility model is to provide a novel bipyramid degree expansion pipe, hemodialysis is the indispensable auxiliary instrument at establishing passageway in-process expansion pipe, because hemodialysis pipe external diameter is thicker (12F or 11.5F), results in the expansion pipe external diameter great, needs two different external diameter expansion pipes to carry out twice epidermis expansion in operation process, the utility model discloses a bipyramid degree expansion pipe, the doctor can once accomplish the expansion operation, adopts the reducible medical staff's of bipyramid degree expansion pipe secondary expansion operation, improves work efficiency, reduces the risk, sets up good basis for the later stage blood circulation passageway is established, carries out interim or short-term hemodialysis and purifies blood.

Description

Novel double-taper expansion tube of hemodialysis catheter package

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to novel double taper expansion pipe of hemodialysis catheter package.

Background

Hemodialysis is one of the major renal replacement therapies for patients with renal failure. The establishment of an effective vascular access is the premise that hemodialysis is carried out smoothly, the expansion tube is an indispensable auxiliary instrument in the process of establishing a channel, the expansion tube is required to expand the skin after the puncture is successful, the epidermis is locally expanded, the double-taper expansion tube is placed along the direction of the blood vessel and the extension wire, brute force is avoided, a good foundation is laid for the establishment of a blood circulation channel in the later period in order to protect the extension wire, and temporary or short-term hemodialysis and blood purification are carried out.

Disclosure of Invention

An object of the utility model is to provide a novel double-taper expansion tube of hemodialysis catheter package. The head end of the expansion pipe is rounded and chamfered, the first taper is excessive, and then the second taper is excessive until the bottom end of the pipe seat is the normal size of the expansion pipe, so that the expansion pipe with double tapers is formed.

The technical scheme of the utility model as follows: and (4) forming a double-taper forming die according to the drawing requirements, and forming and processing the expansion pipe according to the die to form the expansion pipe with double tapers.

The utility model discloses the advantage as follows: the double-taper expansion pipe is used by the company, and the double-taper excessively reduces the overlarge skin expansion opening, so that the bleeding phenomenon is caused. The independent double-taper expansion pipe reduces the inconvenience in operation of the traditional clinically used single-taper two expansion pipes. In the process of establishing the hemodialysis channel, the operation can be realized only by using the double-taper expansion tube, so that the hemodialysis channel is convenient for a clinician to use.

Drawings

Fig. 1 is a schematic view of an expanding tube structure of the present invention.

Fig. 2 is a schematic diagram of the double-taper expansion pipe of the present invention after forming.

Fig. 3 is a cross-sectional view of the double-taper expansion pipe of the present invention after forming.

Detailed Description

As shown in fig. 1, 2 and 3, a double taper expansion pipe includes a pipe socket and a main pipe. Fig. 2 is a view of the double-tapered expansion pipe formed by the die of fig. 1. A 1.8mm transition to 3.3mm forms a first taper and a 3.3mm transition to 4.1mm forms a second taper. FIG. 3 is a cross-sectional view of the double-tapered dilation tube after it has been formed. The skin opening can be expanded only by using the double-taper expansion tube clinically, so that the operation steps of medical personnel are reduced, and the working efficiency is improved.

Claims

1. The utility model provides a double taper expansion pipe of novel hemodialysis catheter package, its characterized in that, the double taper expansion pipe of adoption comprises tube socket and main pipe, and the tube socket material is polypropylene, is responsible for the material and is polyethylene, and double taper expansion pipe tube socket is inlayed with the main pipe material and is annotated fixedly, carries out most advanced forming processing and makes the finished product, forms the double taper.

2. A double tapered dilation tube according to claim 1 wherein the first taper of the dilation tube is 6-10mm long at the head end and the second taper is 15-25mm long from the end of the first taper.

3. A double tapered dilation tube according to claim 1 wherein the first taper of the dilation tube has a minimum outer diameter of 1.5 to 3.3mm and the second taper of 3.3 to 4.1 mm.
