DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cuff band of a sphygmomanometer for measuring blood pressure by, for example, wrapping it around an arm.

[0002]

2. Description of the Related Art Conventionally, a cuff band of a sphygmomanometer is welded by a high-frequency welder using, for example, a cloth made of soft vinyl chloride or a cloth laminated with soft vinyl chloride or urethane. .

[0003]

However, in the case where soft vinyl chloride is used as the material of the cuff band that hits the skin surface, the soft vinyl chloride is unsuitable from the viewpoint of the texture, while the soft cuff band is soft as the material of the cuff band. In the case of using a laminate obtained by laminating vinyl chloride, urethane, or the like, there is a drawback in that the elasticity of the fabric to the skin surface is deteriorated, the efficiency of blood pressure is inhibited, and a correct blood pressure value cannot be measured.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an inexpensive cuff band for a sphygmomanometer capable of measuring blood pressure stably and having good touch.

[0005]

In order to solve the above-mentioned problems, the present invention is directed to a belt-shaped outer casing 2 in which a portion of the outer casing 2 which is in contact with the skin is made of a material having good elasticity. The air bag 3 for blood ischemia is accommodated, a flange portion 6 is protruded at least at an outer peripheral portion along the length direction of the air bag 3, and a slit hole 7 is formed along the flange portion 6 and the flange portion 6 is formed. The outer peripheral portion 8 is welded to the jacket 2 rather than the slit hole 7 of the portion 6.

[0006]

According to the present invention, a flange portion 6 is protruded from an outer peripheral portion of an air bag 3 accommodated in a band-shaped outer cover 2, and a slit hole 7 is formed along the flange portion 6, and a flange hole 6 is formed. Since only the outer peripheral portion 8 is welded to the jacket 2 rather than the slit hole 7 of the portion 6, the air bag 3 can be securely fixed to the jacket 2 by the high frequency welder, and the slit hole 7 of the flange portion 6 can be fixed. Since the inner peripheral portion 9 is not welded to the outer cover 2, the air bag 3 is not affected by the flange portion 6.
Can be inflated. Here, when the air bag 3 is inflated, the outer peripheral portions 8 along the length direction thereof are pulled inward, and the slit holes 7 are formed at least in the air bag 3.
Is formed on the flange portion 6 along the length direction of the air bag 3 so that the air bladder 3 expands without being displaced with respect to the jacket 2. Therefore, the artery can be occluded with the correct air pressure, so that the ischemia efficiency is not hindered and stable blood pressure measurement can be performed. Furthermore, since the portion of the jacket 2 that is in contact with the skin is made of a cloth with good elasticity, the elasticity of the cloth to the skin surface is improved when measuring blood pressure,
The efficiency of blood pressure is further improved.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. The cuff band 1 used in this embodiment is shown in FIG.
(A) As shown in (b), the right half of the band-shaped outer cover 2 is formed into a bag shape, and the air bag 3 for blood ischon is stored therein, and the right end surface of the outer cover 2 is formed on the right end surface. One magic fastener 4 is welded, while the other magic fastener 5 is welded to the left half of the jacket 2, the jacket 2 is wound around the arm, and the two magic fasteners 4 and 5 are detachably engaged. In the state
By sending air into the air bag 3, the artery is blocked and blood pressure can be measured.

[0008] The jacket 2 is formed by laminating a short outer cloth 2B on the right half of a long outer cloth 2A, and the outer peripheral edges of both outer cloths 2A, 2B are welded by a high frequency welder. In this state, the long outer cloth 2A constitutes a surface portion of the outer cover 2, and the short outer cloth 2B constitutes a part in contact with the skin. As the short outer cloth 2B, a cloth with relatively good elasticity is used, and a non-stretchy cloth obtained by laminating soft vinyl chloride, urethane, or the like as in the past is not used. At the time of blood pressure measurement, the skin is improved so that the efficiency of arterial ischemia is not hindered. Further, since the reliable welding strength can be ensured by the high frequency welder without using sewing or the like, the cuff band 1 can be obtained at low cost and with simple processing.

The air bag 3 for blood ischemia is a long outer cloth 2A.
And a short outer cloth 2B. As shown in FIG. 3, the air bag 3 is formed by stacking two blood blocking sheets 3A and 3B, and an air nozzle 5 for sending air is fitted to the blood blocking sheet 3A on the front side. ing. Further, as shown in FIG. 2, a flange portion 6 is protruded from an outer peripheral portion of the air bag 3. Slit holes 7, 7 ′ are formed along each flange portion 6, and the outer peripheral portion 8 of each slit hole 7, 7 ′ in the flange portion 6 is welded to the jacket 2, The inner peripheral portion 9 of each of the slit holes 7 and 7 ′ in FIG. 6 is divided into a portion that is not welded to the jacket 2.

Next, in manufacturing the cuff band 1,
First, the air bag 3 is superimposed on the short outer cloth 2B as shown by the arrow a in FIG. 2, and the outer peripheral edges of the outer cloths 2A and 2B, which are less weldable than the conventional soft vinyl chloride or the like, and the air bag. The outer peripheral portion 8 is more securely welded to the outer peripheral portion 8 than the slit holes 7 and 7 'of the flange portion 6 by a high-frequency welder (the state of FIG. 4). On the other hand, one magic fastener 4 is previously welded to the right end of the long outer cloth 2A. Next, in a state where the other magic fastener 5 is juxtaposed on the short outer cloth 2B, the long outer cloth 2A is superimposed on the short outer cloth 2B and the other magic fastener 5, and the high frequency welder is used. The outer cloths 2A and 2B and the other magic fastener 5 are welded to each other to obtain the cuff band 1 having a reliable welding strength.

Here, only the outer peripheral portion 8 of the air bag 3 is sandwiched between the outer peripheral portions 8 of the flange portion 6 and the slit holes 7 and 7 'between the outer cover 2 (a pair of outer cloths 2A and 2B) and welded by a high frequency welder. Thereby, the air bag 3 can be securely fixed to the jacket 2. Moreover, the slit holes 7 in the flange portion 6,
Since the inner peripheral portion 9 is not welded to the jacket 2 than 7 ', the air bag 3 can be inflated without the influence of the flange portion 6. At this time, as shown in FIGS. 5 and 6, when the air nozzle 3 of the air bag 3 is connected to the tube 20 and the air bag 3 is inflated, the outer peripheral portions 8 along the length direction of the air bag 3 are pulled inward. And the slit holes 7,
By forming the flange portion 6 provided with 7 ′ on the outer peripheral portion of the air bag 3, the air bag 3 expands without being displaced with respect to the jacket 2. Therefore, the artery can be occluded with the correct air pressure, so that the ischemia efficiency is not hindered and a stable blood pressure value can be measured.

In the above embodiment, the flanges 6 are formed on the four sides of the air bag 3 and the slits 7 and 7 'are formed in each flange 6, but the slits 7 are formed in the air bag 3. You may make it provide only in the flange part 6 along the length direction at least. In this case, when the air bag 3 is inflated, the outer peripheral portions 8 along the length direction of the air bag 3 are greatly pulled inward, so that the slit holes 7 are formed at least in the flange portions 6 along the length direction of the air bag 3. By forming the air bag 3, the air bag 3 can be inflated without being displaced with respect to the jacket 2.

[0013]

As described above, according to the present invention, the portion of the belt-shaped outer jacket which is in contact with the skin is made of a highly stretchable fabric, and the outer jacket contains an air bag for blood ischemia. A flange portion is protruded at least at an outer peripheral portion along the length direction of the air bag, and a slit hole is formed along the flange portion, and an outer peripheral portion of the air bag is welded to the jacket body more than the slit hole. With this configuration, the air bag can be reliably welded without displacing the air bag with respect to the outer cover, and the inner peripheral portion of the flange portion is not welded to the outer cover than the slit hole. Since the air bladder can be inflated without being displaced with respect to the jacket without being affected by the part, stable blood pressure measurement can be performed. In addition, a reliable welding strength can be ensured by a high-frequency welder without using sewing or the like, and a cuff band can be manufactured by inexpensive and simple processing. Further, since the portion of the outer body that comes into contact with the skin is made of stretchable fabric, unlike the case of using a laminated non-stretchable fabric such as conventional soft vinyl chloride, The elasticity of the fabric is improved, and the efficiency of blood pressure is further improved. As a result, an inexpensive cuff band having high reliability and good texture can be obtained.
