【表】Detailed Description of the Invention <Industrial Application Field> The present invention relates to a cannula used as an introduction part of a catheter. This invention relates to an easily split cannula that can be easily removed by tearing it lengthwise. <Prior art> A synthetic resin cannula called an indwelling needle functions as an introduction part for smoothly introducing a long catheter into a body cavity. Its presence interferes with subsequent procedures. Therefore, a type of synthetic resin cannula that can be removed by tearing or splitting the cannula as an introduction part lengthwise after catheter insertion has been developed (Publication of Utility Model Publication No. 1661/1989, Japanese Patent Publication No. 1661/1983, Japanese Patent Publication No. 1661/1983).
Publication No. 59146, Publication No. 61-50464, Special Publication No. 2-
Publication No. 7670, etc.). The idea disclosed in Japanese Utility Model Publication No. 1661/1983 is to grasp the handle means and apply force in the direction perpendicular to the longitudinal axis to open the indwelling needle along the weakened part of the separation line (multiple slits or perforations). The invention disclosed in Japanese Patent Publication No. 61-59146 discloses a catheter (a catheter that is split longitudinally) made of a material in which a base polymer is uniformly mixed with a modified polymer that is incompatible with the base polymer. easy), Tokuhei 2-7670
The invention of the No.
This catheter is disclosed in Japanese Patent No. 61-59146 and has two parallel striated bands made of a modified polymer interposed therebetween. Moreover, the invention of Japanese Patent Publication No. 61-50464 is
A plurality of striations mixed with inorganic powder having X-ray contrast properties are provided along the axial direction of the base body of the catheter. However, these conventional techniques, for example, in the device disclosed in Japanese Utility Model Publication No. 1661/1983, have the fatal drawback that the blood flowing in during puncture leaks out from the separation line, and is extremely painful. Not only that, but there is also a possibility that it may be torn into pieces during tearing. In addition, Tokkosho using modified polymers
The inventions of Japanese Patent Publication No. 61-59146 and Japanese Patent Publication No. 2-7670, and the invention of Japanese Patent Publication No. 61-50464,
The tear strength is still too high, and when a large amount of force is applied to remove the cannula, the cannula may move and cause pain to the patient. <Problem to be solved by the invention> The present invention has been made in view of the above circumstances.
It is an object of the present invention to provide an easily split cannula that does not leak blood and has appropriate tear strength. <Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention provides a tube composed of a plurality of longitudinally extending bands made of synthetic resin, in which one of the adjacent bands is It is made of polypropylene, and the other side of the adjacent band has a weight ratio of polypropylene to polyurethane.
65-95 weight%: 35-5 weight% (hereinafter referred to as weight%)
An easily split cannula made of a material mixed at a ratio of (expressed as wt%) is used. <Function> Since the cannula of the present invention is constructed as described above, the adhesive strength at the joint between the bands is weak, and the cannula easily tears at the boundary between the bands. <Example> Next, an example of the present invention will be described. The cannula of the present invention is a tube made of synthetic resin that is composed of a plurality of longitudinally extending strips, and adjacent strips can be easily separated from each other. Adjacent bands may be formed using any material as long as they can be easily separated, but one of the adjacent bands is made of the first synthetic resin, and the adjacent bands are made of the first synthetic resin. The other one is preferably made of a material made by mixing a first synthetic resin with a second synthetic resin that is incompatible with the first synthetic resin, and the first synthetic resin is polypropylene or polyethylene. , polyester, etc., and polyurethane can be used as the second synthetic resin, and a combination of polypropylene and polyurethane is particularly preferred. In the case of a combination of polypropylene and polyurethane, the mixing ratio is approximately 65 to 95 wt%: 35
~5wt%. Incidentally, one side of the band may be mixed with a pigment or an inorganic powder having X-ray contrast properties such as barium sulfate, tungsten carbide, or zirconium oxide, and the base of the cannula may be filled with a suitable wing-shaped tab or the like. Gripping means may also be provided. Next, the operation of tearing the cannula of the present invention will be explained using the drawings (FIG. 1). In FIG. 1, 1 is a cannula, 2 is a band formed from a first synthetic resin, 3 is a band formed from a mixture of the first synthetic resin and a second synthetic resin, and 4 is a band. 2 and 3, and 5 and 6 are gripping parts. When gripping parts 5 and 6 are grasped by hand and pulled in a direction perpendicular to the longitudinal axis in a direction in which 5 and 6 are separated, cannula 1 is easily torn at boundary 3, and bands 2 and 3 are separated. separated. [Examples 1 to 5] Using two extrusion molding machines (manufactured by Plastic Engineering Research Institute, UT25H, UT32H), one molding machine was filled with polypropylene, and the other molding machine was filled with polypropylene and polyurethane. 95wt% in ratio:
5wt%, 90wt%: 10wt%, 80wt%: 20wt%,
A mixture of 70wt%:30wt% and 65wt%:35wt% was filled, and a tube consisting of two strips was manufactured using these two molding machines. Regarding the obtained tube (outer diameter 2.1 mm, inner diameter 1.75 mm),
The tear strength was measured by the following method using a tensile tester (S-500, manufactured by Shimadzu Corporation). That is, a 20 mm slit was provided at the base end of a tube with a total length of 70 mm, and the grip part was attached to a tensile tester in the state shown in FIG. 1, and the force required for tearing was measured. The results are shown in Table 1. Tear strength is 0.1~0.3
It has an appropriate strength of Kg, and did not break during cannula puncture, and did not damage the cannula puncture area when removing the cannula. [Comparative Example 1] Polyurethane and a mixture of polyurethane and polypropylene in a ratio of 80wt%:20wt% were prepared, similar tubes were manufactured using the same molding machine as in Examples 1 to 5, and similar tests were conducted. Ivy. The results are shown in Table 1. [Comparative Example 2] Polypropylene and a mixture of polypropylene and polyurethane at a ratio of 40wt%:60wt% were prepared, and similar tubes were manufactured using the same molding machine as in Comparative Example 1, and the same tests were conducted. . The results are shown in Table 1. [Comparative Example 3] Polypropylene and a mixture of polypropylene and polyethylene at a ratio of 20wt%:80wt% were prepared, and similar tubes were manufactured using the same molding machine as in Comparative Example 1, and similar tests were conducted. . The results are shown in Table 1. <Effects of the Invention> As is clear from the above explanation, since the cannula of the present invention has an appropriate adhesive strength between the bands, it will not break during puncture of the cannula or when the cannula is removed. The catheter can be safely introduced into the patient's body cavity without damaging the puncture site. 【table】
