Problems solved by technology

When the exposed portion 190 is formed, the air bladder 150 cannot effectively and uniformly press the wrist 300, so sufficient blood blocking performance cannot be obtained, which causes a decrease in measurement accuracy.
In addition, at both ends of the bonded portion of the air bag 150 and the collar 170 (area A shown in the figure), since a force is applied in a direction in which the air bag 150 is peeled off from the collar 170, there is a possibility of adhesion. Department of Reliability Declines
[0013] The above-mentioned lateral deviation phenomenon is more likely to occur when the thickness of the expansion-contraction space 166 inside the air bag 150 is larger relative to the width of the air bag 150 when it is inflated. In the structure in which pads are formed at the end portions on both sides of the air bag 150, this lateral offset phenomenon is particularly problematic.
However, the above-mentioned problems are not limited to the cuffs for blood pressure monitors with such a structure, and often occur even in cuffs for blood pressure monitors that do not have pads formed at both ends of the air bag, so they need to be solved urgently.

Embodiment 1

[0102] Figure 5A It is a schematic perspective view showing a part of the air bag built in the cuff for blood pressure monitor according to Example 1 of the present embodiment by cutting away. Figure 5B is along Figure 5A A schematic cross-sectional view of the VB-VB line shown in, Figure 5C is along Figure 5A A schematic cross-sectional view of the VC-VC line shown in . in addition, Image 6 is in Figure 5C Magnified view of region VI shown in .

[0103] Such as Figure 5A to Figure 5C As shown, the air bag 150A of the blood pressure cuff of this embodiment is formed in a bag shape using two resin films 151 and 152 . More specifically, the air bag 150A is formed by laminating a substantially rectangular resin film 151 in plan view and a substantially rectangular resin film 152 slightly wider than the resin film 151 in plan view, and fusing their peripheries together. There is an expansion and contraction space 166 inside.

[0104] The resin film 152 forms an in...

Embodiment 2

[0114] Figure 7A It is a schematic perspective view showing a part of an air bag built in a blood pressure cuff according to Example 2 of the present embodiment, cut away. Figure 7B is along Figure 7A A schematic cross-sectional view of line VIIB-VIIB shown in Figure 7C is along Figure 7A A schematic cross-sectional view of line VIIC-VIIC shown in . in addition, Figure 8 is in Figure 7C Magnification of region VIII shown in .

[0115] Such as Figure 7A to Figure 7C As shown, the air bag 150B of the blood pressure cuff of this embodiment is formed in a bag shape using four resin films 151 , 152 , 153 , and 154 . More specifically, the air bag 150B laminates two resin films 151, 154 that are substantially rectangular in plan view, and connects the two resin films 151, 154 with narrow resin films 152, 153 that are substantially rectangular in plan view. Formed at the side end. These resin films 151, 152, 153, 154 are connected together by welding the peripheries ...

Embodiment 3

[0124] Figure 9A It is a schematic perspective view showing a part of an air bag built in a sphygmomanometer cuff according to Example 3 of the embodiment of the present invention cut away. Figure 9B is along Figure 9A A schematic cross-sectional view of line IXB-IXB shown in, Figure 9C is along Figure 9A A schematic cross-sectional view of line IXC-IXC shown in . in addition, Figure 10 is in Figure 9C Magnification of region X shown in .

[0125] Such as Figure 9A to Figure 9C As shown, the air bag 150C of the blood pressure cuff of this embodiment is formed in a bag shape using four resin films 151 , 152 , 153 , and 154 . More specifically, the air bag 150C is formed by laminating two resin films 151 and 152 that are approximately rectangular in plan view, and welding their peripheries together to form a first bag body with a first expansion and contraction space 166a inside. Two resin films 153, 154, which are approximately rectangular in plan view, are weld...

Abstract

The cuff for a sphygmomanometer of the present invention has an air bag (150D) that expands and contracts when air flows in and out. The air bag (150D) includes: an inner wall portion (162) positioned inside when the blood pressure cuff is wound around the wrist; an outer wall portion (161) positioned outside the inner wall portion (162); The side wall portion (163), which connects the side end portion of the inner side wall portion (162) and the side end portion of the outer side wall portion (161), is folded toward the inside of the air bag (150) in a contracted state, thereby forming a The side ends of (150D) form pads. A welded portion (168) for reducing the expansion of the pad formed by the side wall portion (163) is provided in a part of the air bag (150D) in the direction of winding toward the body. With such a configuration, it is possible to prevent the occurrence of the phenomenon of lateral deviation of the cuff, and it is possible to obtain a high-performance and highly reliable blood pressure monitor.

Description

technical field [0001] The present invention relates to a cuff for a sphygmomanometer having a fluid bag that blocks blood circulation in an artery by compressing the body, and a sphygmomanometer having the cuff. Background technique [0002] Usually, when blood pressure is measured, a cuff containing a fluid bag for compressing an artery inside the body is wrapped around the body surface of the body, and the wrapped fluid bag is pressurized and depressurized, thereby The blood pressure value is measured by detecting the arterial pressure pulse wave generated in the artery. Here, the so-called cuff refers to a belt-shaped structure having a lumen, which can be wound around a part of the body, and is used for measuring arterial pressure of the upper and lower limbs by injecting fluid such as gas or liquid into the lumen. Therefore, a cuff is a term that includes a fluid bag and a winding member for wrapping the fluid bag around the body. In particular, a cuff that is wound a...
