Description

[Detailed description of the invention] The present invention is mainly concerned with the improvement of a compression band for blood pressure measurement by improving the way the pipe is attached and the structure of the air bag. A band constructed by polymerizing an inner plate 1 made of a resin sheet and an outer plate 2 made of a thermoplastic synthetic resin sheet containing a core thread, and fixing the entire periphery or appropriate parts to each other by high-frequency welding or thermal bonding. body 3
A thermoplastic synthetic resin sheet bag forming part forming plate 4 is superposed on the inside of the inner surface plate 1, and the entire periphery of the bag forming part forming plate 4 is airtightly fixed to the inner surface plate 1 by high frequency welding and thermal bonding. Therefore, when the band 3 is wrapped around the arm and air is blown, the air bag portion 5 cannot bulge outward due to the non-extensibility of the outer surface plate 2 containing the core yarn, but bulges inward. is formed on the inside of the inner surface plate 1, and separately formed on the mounting seat 6 by molding a thermoplastic synthetic resin material to connect the connecting pipe 8 of the air pressure gauge 7 and the hand-throttled air supply/drainage pump. A pipe body 11 is constructed with a connecting pipe part 10 of 9, and the mounting seat part 6 is connected to a through hole 12, 12' provided in advance in the bag part forming plate 4.
Attach the pipe body 11 to the bag forming plate 4 by airtightly fixing it to the inside of the incisal edge by high frequency welding and thermal bonding,
The pipe parts 8, 10 of this pipe body 11 are connected to the above-mentioned through holes 12, 12' and the through holes 1 made in advance in the outer surface plate 2.
3 and 13', and in the figure, 14 and 14' are hook-and-loop fasteners that fasten the ends of the band 3 when it is wrapped around the arm.

In the embodiment shown in Figs. 1 and 2, the outer plate 2 is made of a thermoplastic soft synthetic resin sheet containing a yarn core, and the inner plate 1 and the bag forming plate 4 are made of a thermoplastic sheet without a yarn core. It is made of a plastic soft synthetic resin sheet, and the size of the inner surface version 1 and the outer surface version 2 are the same size, and furthermore, the end stop of the band body 3 is made by folding the same end in half through a connecting ring 15, In addition, in the embodiment shown in FIGS. 3 and 4, the outer surface version 2 is made of a thermoplastic soft synthetic resin sheet containing a yarn core, and the inner surface version 1 and the bag-forming version 4 are made of a thermoplastic sheet without a yarn core. It is made of a plastic soft synthetic resin sheet, the size of the inner plate 1 is half the size of the outer plate 2, and the end of the band 3 can be wound without using a connecting ring.

As described above, the present invention involves polymerizing the inner surface 1 made of a thermoplastic synthetic resin sheet without a core yarn and the outer surface 2 made of a thermoplastic synthetic resin sheet containing a core yarn, and mutually bonding the entire periphery or appropriate portions. A thermoplastic synthetic resin sheet bag forming plate 4 is superposed on the inside of the inner plate 1 of the band 3, which is fixed by high frequency welding and thermal adhesion. By airtightly fixing the periphery to the inner surface version 1 by high-frequency welding and thermal bonding, when the band 3 is wrapped around the arm and air is blown, the non-extensibility of the outer surface version 2 containing the core thread causes it to move outward. Since the air bag portion 5 which cannot be inflated and bulges inward is formed inside the inner surface plate 1, when the air bag portion 5 is inflated by blowing air into the air bag portion 5 during use. The outer surface plate 2 prevents the air bag portion 5 from expanding outward and causes the air bag portion 5 to expand inwardly, thereby improving the functionality of the air bag portion 5,
In other words, this has the beneficial effect of reducing the air supply amount and air supply time to the extent that the air bag portion 5 does not bulge outward.
Further, a pipe body 11 is formed by molding a thermoplastic synthetic resin material and integrally has a pipe part 8 for connecting the air pressure gauge 7 and a pipe part 10 for connecting the hand-throttled air pump 9 on the mounting seat part 6. The mounting seat 6 is airtightly fixed to the inside of the incisal edge of the through holes 12, 12' previously provided in the bag forming plate 4 by high frequency welding and thermal bonding, and the pipe body 11 is formed into a bag. Since it is attached to the plate 4, the high frequency welding and thermal bonding work of the mounting seat 6 to the bag forming plate 4 can be efficiently and easily performed on a flat surface, and the high frequency welding, The heat-bonded parts are not completed by folding in half, but have favorable advantages in terms of strength, appearance, etc.
0 is a through hole 12 made in the inner surface plate 1 and the outer surface plate 2,
Since the pipe body 11 is brought out through the pipes 12', 13, and 13', the base of the pipe body 11 is hard to be damaged and is strong.
