JPH0670892A - Cuff band for tonometer - Google Patents

Abstract

PURPOSE:To provide the soft and inexpensive cuff band for tonometer capable of stable blood pressure measurement. CONSTITUTION:As a part coming in contact with the skin of a band-shaped cover 2 is made of an elastic material, the good elasticity of the material to the skin can be obtained in measuring the blood pressure. The cover 2 houses an air bag 3 for stopping the blood flow. A flange section 6 is projected to an outer peripheral section along at least the longitudinal direction of the air bag 3 and a slit hole 7 is formed along the flange section 6. An outer peripheral section 8 located outside the slit hole 7 on the flange section 6 is welded to the cover 2 by high-frequency welder and an inner peripheral section 9 located inside the slit hole 7 is not welded to the cover 2. Thus, the air bag 3 can be inflated without the influence of the flange section 6 and the stable measurement of the blood pressure can be performed with proper air pressure.

[0003]

SUMMARY OF THE INVENTION However, in the case of using soft vinyl chloride as the conventional fabric for the cuff band that touches the skin surface, soft vinyl chloride is unsuitable from the viewpoint of the texture, while soft as the fabric for the cuff band. The one using a laminate of vinyl chloride, urethane or the like has a drawback that the stretchability of the cloth on the skin surface is deteriorated, the blood pressure blocking efficiency is hindered, and a correct blood pressure value cannot be measured.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an inexpensive cuff band for a sphygmomanometer, which enables stable blood pressure measurement and is comfortable to the skin.

[0005]

In order to solve the above-mentioned problems, according to the present invention, the portion of the band-shaped outer jacket 2 that comes into contact with the skin is made of a highly stretchable cloth, and the outer jacket 2 has An air bag 3 for blood flow prevention is housed, a flange portion 6 is projectingly provided on an outer peripheral portion of the air bag 3 along at least the length direction, a slit hole 7 is formed along the flange portion 6, and the flange is formed. The outer peripheral portion 8 is welded to the outer casing 2 rather than the slit hole 7 of the portion 6.

[0006]

According to the present invention, the flange portion 6 is provided so as to project on the outer peripheral portion of the air bag 3 housed in the strip-shaped jacket 2, and the slit hole 7 is formed along the flange portion 6, and the flange is formed. Since only the outer peripheral portion 8 is welded to the outer casing 2 than the slit hole 7 of the portion 6, the air bag 3 can be securely fixed to the outer casing 2 by the high frequency welder, and the slit hole 7 of the flange portion 6 is formed. Since the inner peripheral portion 9 is not welded to the outer body 2 than the outer peripheral portion 9, 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, respectively, so that the slit holes 7 are at least filled with the air bag 3.
By forming the flange portion 6 along the length direction of the air bag 3, the air bag 3 is inflated without being displaced with respect to the outer cover 2. Therefore, since the arterial blood can be blocked by the correct air pressure, the blocking efficiency is not hindered, and stable blood pressure measurement can be performed. Furthermore, since the portion of the outer cover 2 that comes into contact with the skin is made of a material having good elasticity, the elasticity of the material on the skin surface is improved during blood pressure measurement,
Blood pressure is more efficiently blocked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The cuff band 1 used in this embodiment is shown in FIG.
As shown in (a) and (b), the right half of the belt-shaped jacket 2 is formed in a bag shape, and the air bag 3 for blood ischemia is housed therein, and the right end surface of the jacket 2 is formed. One of the magic fasteners 4 is welded, while the other magic fastener 5 is welded to the left half of the outer jacket 2, and the outer jacket 2 is wound around the arm so that the two magic fasteners 4 and 5 are detachably engaged. With the condition
By sending air into the air bag 3, the blood flow can be measured by blocking the artery.

The outer 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 portion in contact with the skin. As the short outer cloth 2B, a relatively stretchable cloth is used, and the conventional non-stretchable cloth laminated with soft vinyl chloride or urethane is not used. When measuring blood pressure, the skin feels good and the arterial ischemic efficiency is not impaired. Further, since the reliable welding strength can be secured by the high-frequency welder without using sewing or the like, the cuff band 1 can be obtained at low cost and by simple processing.

The blood bag 3 for blood flow prevention is a long outer cloth 2A.
It is housed in the hollow portion surrounded by the 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 front-side blood-blocking sheet 3A. ing. Further, as shown in FIG. 2, a flange portion 6 is provided so as to project on the outer peripheral portion of the air bag 3. Slit holes 7 and 7 ′ are formed along the respective flange portions 6, and the outer peripheral portion 8 of each of the slit holes 7 and 7 ′ in the flange portion 6 is welded to the casing 2 and the flange portion. An inner peripheral portion 9 of each slit hole 7, 7'in 6 is divided into a portion which is not welded to the outer casing 2.

Next, in producing the cuff band 1,
First, the air bag 3 is superposed on a short outer cloth 2B as shown by an arrow a in FIG. 2, and the outer peripheral edges of the outer cloths 2A and 2B having poorer welding properties than the conventional soft vinyl chloride and the like, and the air bag. The slit portion 7, 7'of the flange portion 6 of 3 is securely welded to the outer peripheral portion 8 by a high frequency welder (state of FIG. 4). On the other hand, one magic fastener 4 is previously welded to the right end portion of the long outer cloth 2A. Next, in a state where the other magic fastener 5 is arranged side by side on the short outer cloth 2B, the long outer cloth 2A is overlaid 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 flange portion 6 of the air bag 3 rather than the slit holes 7 and 7'is sandwiched between the outer casing 2 (a pair of outer cloths 2A and 2B) and welded by a high frequency welder. As a result, the air bag 3 can be securely fixed to the outer cover 2. Moreover, the slit hole 7 of the flange portion 6,
Since the inner peripheral portion 9 is not welded to the outer casing 2 than 7 ', the air bag 3 can be inflated without the influence of the flange portion 6. At this time, as shown in FIG. 5 and FIG. 6, when the air nozzle 5 of the air bag 3 is connected to the tube 20 to inflate the air bag 3, the outer peripheral portions 8 along the length direction of the air bag 3 are pulled inward. The slit hole 7,
By forming the flange portion 6 provided with 7'on the outer peripheral portion of the air bag 3, the air bag 3 is inflated without being displaced with respect to the outer casing 2. Therefore, since the artery can be blocked with the correct air pressure, the blocking efficiency is not hindered and a stable blood pressure value can be measured.

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

[0013]

As described above, according to the present invention, the portion of the band-shaped outer covering that comes into contact with the skin is made of a highly stretchable fabric, and the outer covering contains an air bag for blood ischemia. A flange portion is provided so as to project at least on the outer peripheral portion along the length direction of the air bag, and a slit hole is formed along the flange portion, and the outer peripheral portion is welded to the outer jacket than the slit hole of the flange portion. With this configuration, the air bag can be reliably welded to the outer cover without being displaced, and the inner peripheral portion of the flange portion is not welded to the outer cover than the slit hole of the flange portion. Since the air bag can be inflated with respect to the outer cover without being displaced, the blood pressure can be stably measured. Further, the welding strength can be secured by the high-frequency welder without using sewing or the like, and the cuff band can be manufactured by an inexpensive and simple process. Furthermore, since the part in contact with the skin of the outer cover is composed of a stretchable fabric, unlike the case of using a conventional non-stretchable fabric laminated such as soft vinyl chloride, the The stretchability of the fabric is improved, and the efficiency of blood pressure blockage is further improved. As a result, it is possible to obtain an inexpensive cuff band that is highly reliable and has a good texture.
