の透過率は、DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Application Field) This invention relates to a balloon used in medical equipment, particularly a laser beam therapy device. (Prior Art) In the conventional technology regarding this balloon, for transparent balloons, powdered vulcanizing agents and vulcanization accelerators were used, but the amount thereof was reduced. Therefore, since the amount of vulcanizing agent was small, the strength inevitably tended to decrease. Therefore, it has been common practice to compensate for this decrease in strength by increasing the thickness. In addition, conventional balloons required technology such as transparency, which was not considered due to their functions, and required a thin rubber body. The reason for this is that it is used to stop blood within a blood vessel, and this purpose is achieved by inflating the balloon. Therefore, a thin rubber was required to allow for good expansion, and the technical means of making a thin and strong rubber was nothing more than that. (Problems to be Solved by the Invention) The balloon manufacturing technology of the present invention lies in the production of a balloon rubber body that is transparent, thin, and satisfies the required strength. Structure of the Invention (Means for Solving Problems) First, the present invention focuses on reducing the use of powdered drugs as much as possible, focusing on natural rubber latex as the main component, and using liquid drugs instead, The following is a combination example. Natural rubber latex 0.8 parts by weight of powdered vulcanizing agent, 0.3 parts by weight of powdered vulcanization accelerator, 0.7 parts by weight of liquid vulcanization accelerator, and 1.0 parts by weight of liquid anti-aging agent are mixed with 100 parts by weight of natural rubber latex rubber. The compounding method is to add a vulcanizing agent and a vulcanization accelerating aid dispersed in natural rubber latex, then add a vulcanizing accelerator and an anti-aging agent, and place the mixture in a constant temperature bath at 10 to 15℃ for 12 hours.
After leaving it for ~24 hours, place it in a constant temperature bath at 25~35℃ for ~24~
The mixture is left to mature for 48 hours, and a balloon immersion mold is immersed in it.Natural rubber latex is adhered to the mold to form a film-like material, which is heated and vulcanized to make a balloon. For example, the conventional balloon formulation is: natural rubber latex (rubber content) 100 parts by weight, vulcanizing agent 1.0-1.5, vulcanization accelerator 0.7-1.5, vulcanization accelerator 0.5-1.0, anti-aging agent 0.5-1.0, and the strength is low. However, transparency does not emerge. In addition, an example of the formulation of a conventional transparent rubber product (nipple) is: natural rubber latex (rubber content) 100 parts by weight, vulcanizing agent 0.5, vulcanization accelerator 0.1, vulcanization accelerator 0.7, anti-aging agent 0.5-1.0. Although it satisfies transparency, it is not possible to maintain strength at the desired thickness. As described above, the conventional technology has various drawbacks. (Example) Natural rubber latex (rubber content) 100 parts by weight (poly-1,4-isoprene) Vulcanizing agent (colloidal sulfur) 0.8 Vulcanization accelerator (zinc oxide) 0.3 Vulcanization accelerator (dithiocarbamate type)
0.7 Anti-aging agent (paraffin emulsion)
The compounding method is to add a vulcanizing agent and a vulcanization accelerator that are dispersed in natural rubber latex, then add a vulcanization accelerator and an anti-aging agent, and then heat the mixture in a constant temperature bath at 10 to 15℃ for 12 hours. After leaving it for ~24 hours, place it in a constant temperature bath at 25~35℃.
A balloon mold is immersed in a solution that has been left to mature for 24 to 48 hours, and a cylindrical neck with a thickness of 0.2 mm, a diameter of 5 mm, and a length of 20 mm is connected to a spherical expanding part with a thickness of 0.2 mm and a diameter of 10 mm. It is manufactured by attaching a thin film balloon to a dip mold and heating and vulcanizing it. (Example of use) To explain an example of use of the balloon of the present invention with reference to the drawings, a multipurpose endoscope A includes an objective lens 2 at the tip and two light guides 1 and 1' for illuminating the field of view of the objective lens. There is also a forceps/water supply port 3 for putting in and taking out therapeutic instruments such as physiological saline 4 and laser fiber, and the tip of this port is structured so that it can be moved vertically and horizontally. The tip of this multipurpose endoscope A is coated with a transparent thin film balloon B manufactured according to the present invention, and can be used to observe the stomach, intestines, blood vessels, and bladder immediately after a meal, or to irradiate laser to lesions. It is used for Furthermore, the distal end of the multipurpose endoscope A is covered with a transparent thin film balloon B, and the transparent thin film balloon 4 is coated with a transparent thin film balloon B.
Physiological saline 4 is injected into the balloon B and the balloon B is inflated to push away obstacles and make it possible to see the affected area more clearly. In this way, in order to use the transparent thin film balloon B to cover the tip of the multipurpose endoscope A, if the transparent thin film balloon B is opaque, the image will be unclear and the detection of the lesion will be missed. Due to the danger, the balloon needed to be as transparent as possible. In addition, when considering treatment with YAG laser beams, in the case of balloons made of opaque materials, some of the energy of the laser beams is absorbed by the balloons, and this energy promotes balloon breakage. In addition, a durability test of the balloon of the present invention and a comparison with conventional balloons revealed that the transparent thin film balloon B produced according to the present invention had its inflated portion tripled and was irradiated with a YAG laser beam. The transmittance is

Only 85% transmittance was obtained. Furthermore, the transparent thin film balloon B produced according to the present invention could be irradiated with laser light 50 times, whereas the conventional balloon was damaged after 20 irradiations. (Effects) The present invention provides 0.8 parts by weight of a powdered vulcanizing agent, 0.3 parts by weight of a powdered vulcanization accelerator, 0.7 parts by weight of a liquid vulcanization accelerator, and a liquid anti-aging agent for 100 parts by weight of natural rubber latex rubber. By blending 1.0 parts by weight to form a basic material, and immersing a balloon mold into the basic material and heating and vulcanizing it, a transparent thin film balloon with transparency and strong strength was obtained, and the lesion This represents a great achievement in discovery and treatment.
