Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a pressure bag for a blood pressure monitor or the like, and more particularly to a method of manufacturing a pressure bag and a pressure bag in which an airtight bag and a band are integrally formed.

Conventionally, for example, a pressurized bag l for a blood pressure monitor has a storage bag part 3 formed at one end side of an elongated cloth wrapping 2 as shown in FIG. 1, and a hole 4 is opened at a desired position in the storage bag part 3. A Velcro 5 is sewn to the periphery of the other end of the wrapping 2, and another Velcro is sewn to approximately the center of one side of the wrapping 2, and a separate airtight bag 7 is provided with an air supply device at one end. Air pipe 9 and blood pressure monitor 1 with 8 attached
0 is attached to one end (2), and the airtight bag 7 is inserted into the storage bag portion 3 of the winding device 2 through the opening 4. Therefore, when measuring blood pressure, the airtight bag 7 is Wrap the pressurized bag belt 1 around the bowl with the bag 7 as the winding end, lock it with the Velcro 5 and 6, and feed air into the airtight bag 7 with the air supply device 8 to increase the air tightness of the airtight bag 70 by pulse rate. It is configured to be measured with a blood pressure monitor 10.

By the way, the conventional pressurized bag band J having the above-mentioned structure is a cloth bag as described above, and the airtight bag 7 is separately prepared and housed therein, so that it has the following drawbacks.

(1) Since the wrapper 2 and the airtight bag 7 are manufactured separately, the cost is high.

(2) Since the airtight bag 7 is molded with a metal mold, it is necessary to make a mold, and since a certain amount of fabrication ζ2 causes wear and tear on the mold, the bag must be re-prepared frequently, resulting in high costs.

(3) In order to store the airtight bag 7 in the storage bag section 3, one more step is required, and the labor cost is reflected in higher costs.

(4) Traditionally, blood pressure monitors were for doctors, but in recent years they have been distributed in the general market for the general public's use. Conventional products had many causes of high costs.

This invention was invented for the purpose of eliminating the causes of high costs of conventional products as described above and providing a pressurized bag for supplying blood pressure monitors, etc., at low cost. A process of making a base fabric by integrally bonding synthetic resin sheets on one side, a process of bonding a fixing member Velcro to a predetermined position on the surface of the base fabric, and a process of bonding the two synthetic resin sheets of the base fabric facing each other. Step of polymerizing and placing the end of the trachea at a desired position on the outer peripheral contour of the bag forming part, and heat sealing the outer peripheral contour of the bag forming part so that the mounting hole communicates with the inside of the bag. The present invention relates to a method for manufacturing a pressurized bag for a blood pressure monitor, etc., comprising a step of forming a bag, and a pressurized bag for a blood pressure monitor, etc. manufactured by this manufacturing method.

According to this invention C2 constructed as described above, the conventional pressurized bag belt has a cloth wrapped N band shaped like a bag and another rubber bag is housed therein, but the pressurized bag belt according to the present invention Because the band is integrally formed in the airtight bag, (1) less material is used;
It has many excellent effects such as (2) fewer production steps, (3) production costs can be reduced by 4, (4) weight reduction, and (5) mass commercialization.

An embodiment of the present invention will be described below based on the drawings. ,
Figures 3 and below relate to this invention. Synthetic fiber cloth (nylon cloth)
A synthetic ta' film (vinyl chloride film thickness: 0.13 mm) '13 is bonded to the lower surface of the fabric 12 in a polymerized state using a pressure heat roller (60 to 80°C) to obtain a base fabric 14.

This is cut into a desired shape as shown in Figure 44.

In FIG. 3, the length corresponds to the length of the entire pressurized bag band, and the width corresponds to twice the width of the pressurized bag band. In the figure, reference numerals 15 and 15' indicate the tracheal connection, 16 indicates the bent section, and 23 indicates the cover. In the placed state, the contours of the Velcro 17, 17' are high-frequency bonded to the surface of the base fabric 14 below. Depending on the necessity C1, the pocket 23 is also heat-sealed to the required portion Kr using a synthetic resin sheet or the like.

Next, the base fabric 14 is attached to the synthetic resin sheet 13 from the bent portion 16.
The two sides are folded in half to face each other and polymerized as shown in FIG.

Therefore, between the two tracheal connecting parts 15 and 15', the distal end of the north trachea 18 and 18' is connected to the 70th tube hole 18 (L
, 18'α are positioned so as to communicate with the airtight bag 19, and the outer peripheral contour of the airtight bag 19 forming portion is heat-sealed 20 using a high frequency welding machine to form the front hole 18α of the trachea 18, 18'.

The airtight bag 19 is formed so that 18'α communicates with the inside of the bag 19. In the figure, 21 is a blood pressure monitor, 21' is a supply/exhaust pump, and 2
2 is a heat-sealed portion of the winding band which is the winding N member 24.

The pressurized bag band 24 configured as shown in FIG. Since the wrapping member 24 is attached to the lV bag 9, there is no need to store a separate rubber bag inside the cloth bag as in conventional products, so material costs can be reduced and the weight can be significantly reduced. can. The work of wrapping a rubber bag in a cloth-wrapped mourning bag can be saved.

There is no need for a mold to make rubber bags. Therefore, it has excellent effects such as being able to be supplied at low cost.

The pocket 23 is for storing a pulse-side microphone, etc., and place this part on the arm or thigh to be measured, so that the left end in Fig. 5 is at the bottom and the stone is at the top. It is rolled up and fixed with the fixing members 17 and 17', and the air is sent from the pump 21' to the airtight bag 19, and the pressure is adjusted to measure the blood pressure with the blood pressure plate 21. Alternatively, it can be stored in the pocket 23. Measure the pulse using a microphone, etc.

For the base cloth 14, if a synthetic resin sheet having a heat melting point of the synthetic fiber cloth 12 is used as the synthetic resin sheet 13, pressure bonding using a heating roller is easy, and there is no problem such as crushing the texture of the synthetic fiber cloth 12 on the surface. The beautiful texture can be maintained without causing any blemishes.

In this regard, the combination of woven fabric C vinyl dichloride sheet made of nylon fiber 100-120 denier yarn with a thickness of 010-9 and 15 mm is thermal fusion (double adhesion) using a pressurized heat roller at 60-80°C. This base fabric 14 may be formed by forming a vinyl chloride resin coating layer on the woven fabric 12, but it requires skill to maintain the uniform thickness of the resin coating layer, and if the thickness is uneven, the base fabric 14 may be coated with a vinyl chloride resin coating layer. This is not preferable because it may cause waviness on the fabric surface or hardening of the woven fabric.Please note that the synthetic wood of the bag part to which the fixing member Velcro 17' is attached (separately reinforcing material is used on the sealing surface) The present invention is not limited to the above-described structure.For example, the woven fabric 12 of the base fabric 14 may be made of polyester fiber or other suitable synthetic fiber cloth, and may have a plain texture or a patterned texture. It may be a pattern expressing a pattern or a printed color pattern.Furthermore, instead of a pattern, precautions for use, a guideline for determining measurement values, etc. may be expressed at appropriate places on the surface of the base fabric by printing or other methods.
