Abstract

The present invention relates to a belt-type wrinkled band used for healing a hernia of intervertebral disk or protection the intervertebral disk. In particular, the expansion and contraction by air-injection can be achieved, without using a rubber tube for the contraction and expansion.

Description

Do not use the wrinkle band and the manufacture method thereof of air expansion tube

Technical field

The present invention relates to a kind of wrinkle band; the wrinkle band of fastening and oppressing waist is because air injection and extension up and down; make between lumbar vertebra and the lumbar vertebra and extend; can carry out the treatment and the protection of intervertebral disc, obtain the wrinkle band especially for the air expansion tube that the wrinkle band is extended does not use other rubber tube etc.

Background technology

In the past, can constitute being constructed as follows of wrinkle band and manufactured: have certain width up and down with 100 inside, with with up and down the roughly consistent mode of width, by apparatus for sewing expansible air expansion tube 110 is fixed on and is with on 100, remove the air of air expansion tube 110 then, make band be deformed into the shape of wrinkle band thus.

As such structure, Korea S in the registration of the present patent application people pro-speciallys permit in No. 142202 that registers, disclose a kind of like this structure: axial each air expansion tube 110 is connected to axial mode with folk prescription respectively not to be had on the expansible connection associate member 120, thereafter, make under the air expansion tube 110 expansible states, only air expansion tube 110 is housed in the other pocket 130, make above-mentioned pocket 130 by apparatus for sewing and width with air expansion tube 110 degrees of expansion be with 100 to combine after, remove the air in the air expansion tube 110, can obtain wrinkle band (patent documentation 1) thus.Yet the shortcoming of this structure is to connect associate member 120 to become many, if consider the combination that is connected respectively to the air expansion tube 110 on the described connection associate member 120, all the manual work that adds pressure zone 140 by use is finished, produce following problem so: these a plurality of connection associate members 120, when expanding owing to strong air pressure, these connect the partial rupture that associate member 120 is connected with air expansion tube 110, and owing to can not fasten with identical exerting pressure, and produce escape of air.

Therefore, recently, in order to solve described problem, in No. the 298328th, Korea S's special permission registration, following a kind of structure is disclosed: an air expansion tube 210 is formed zigzags, be located at have certain width with 200 inside, make under the air expansion tube 210 expansible states by injecting air then, by apparatus for sewing it is sewn to and is with on 200, address the above problem (patent documentation 2) thus.

Yet as these shortcomings, when existence forms zigzag with an air expansion tube 210, when the bending section 220 that produces is up and down closely formed, bending section 220 up and down is bent, this bending causes shortcoming that air can not inject and in order to prevent such bending, and forms when crooked than large-spacing ground, owing to can not get strong power, the shortcoming that can not produce a desired effect.

And owing to ensconce in the band in the air expansion tube 210 that will be other like this, when tying up on the waist, under air expansion tube 210 expansible states, can feel foreign body sensation, in addition when expanding, because the width of the middle body of wrinkle band 200 is greater than the width of two side ends, when middle body extends, two side ends in a narrow margin produces and stretches relatively, and middle body curls backward, therefore has the shortcoming of wearing band sense variation.

The specific embodiment

Below, with reference to accompanying drawing most preferred embodiment of the present invention is elaborated, when each accompanying drawing is described, to identical element, even the key element of representing on other accompanying drawing also is marked with identical reference number.

Be illustrated in figure 7 as following formation: in the contour line 1a of bonding eclipsed adhesive sheet 1, at medial surface with certain rules formation one side bonds line 12, guarantee ventilation path 2 thus, above-below direction in the inner space 4 of being guaranteed by the bonding wire 12a five equilibrium of opposite side will be connected with the connection splicing tape 5 of elastic webbing 6 by contour line 1a and by bonding.

At this moment, divide the bonding wire 12a of inner space 4, by not bonding with certain width, form through hole 10, the formation of this through hole 10 can form by the incision ditch 11 of high-frequency work metal die 8 as shown in Figure 3.

And, alternatively form by through hole this through hole 10 and adjacency, when air injects inner space 4, can roughly carry out simultaneously expanding fully and uniformly.

To connect splicing tape 5 and bond to contour line 1a when going up,,, carry out disposable pressurization by pressue device 7 in 8 formation of high-frequency work metal die to connecting elastic webbing 6 and being connected the boundary portion 3 of splicing tape 5 connections as Fig. 1 and shown in Figure 2.

Thereafter, so that when connecting the mode that splicing tape 5 separates along contour line 1a or making it bonding simultaneously, be installed in the pressue device 7 on the high-frequency work metal die 8, preferentially pressurize to the boundary portion 3 of the extended state of keeping elastic webbing 6, push simultaneously, the tensile force of elastic webbing can not to contour line 1a bonding be connected splicing tape 5 transmission, connect splicing tape 5 fusions and become soft, even with contour line 1a when bonding, can do not loaded fully yet, carry out bonding easily, after described bonding the finishing, finish cooling by natural cooling or forced cooling device etc., because of the limpen connection splicing tape 5 of fusion recovers original state, can not produce damage fully when bonding.

At this moment, high-frequency work metal die 8, be by machinery running (not shown) and up and down the running device, the installation metal die 9 of the connection splicing tape 5 that is connected with elastic webbing 6 is installed, by fastening with high-frequency work metal die 8, make that to be installed in the superimposed sheets 1 of installing on the metal die 9 bonding, make contour line 1a and bonding wire 12a, is connected splicing tape 5 and the bonding wire 12a while bonding.

Thereafter, as shown in Figure 2, if the connection splicing tape 5 that will be installed on the electric metal mould 9 is removed from connecting portion 13, because the effect of elastic webbing 6, scrimp is assembled on superimposed sheets 1.

Therefore,, connect also state of splicing tape 5 for not have to damage even because bonding by high frequency, even thereby the expansion repeatedly of inner space 4 and the contraction expansion and the contraction that cause elastic webbing, also can't see the damage of wrinkle band fully.

In addition, because the central part that is shaped as of wrinkle band forms wide relatively width than two side ends, in addition, after upper end-face edge forms cut 14, by with the upside of above-mentioned cut 14 by other peripheral end 15 roll make fixing, the phenomenon that upper end-face edge curls backward when having prevented to extend.

At this moment, if possible, above-mentioned cut 14, upper end-face edge is cut into the U font after, furthered in the upside of cut 14, be sewn with peripheral end 15, leave blank 18.

Such stitching, under the situation that the wrinkle band extends up and down, because the central part of wrinkle band has wide relatively width than two side ends, the part of extending on the wrinkle band is many relatively, the elongation of elastic webbing is many relatively, the two side ends generation few in the part of extending relatively stretches, and when producing the power of curling backward, the blank 18 that produces by described cut 14 can prevent curling backward situation.

And; before being sutured in the peripheral end 15 of band; make the medial surface of band have the protective lining wing 16; the above-mentioned protective lining wing 16 is sewn by other peripheral end 15; this other peripheral end 15 is formed the upper and lower end edge of cover tape; or by the more microscler one-tenth of a side with described peripheral end 15, and form protective lining wing 16a, can realize easy manufacturing.

In addition, fixed parts 17 such as use rivet can prevent situations such as swing thus with the medial surface that the described protective lining wing 16,16a are fixed on band.

In addition, can form the capable auxiliary body 19 of blood in the above-mentioned protective lining wing 16,16a, the capable auxiliary body 19 of this blood has the effect of blood circulation promoting for Magnet, the jade with infrared emission effect, germanium etc.

Therefore, owing to do not use other air expansion tube at the wrinkle band, thereby the interval of expansible inner space closely can be formed the degree that does not almost have spacing distance, be bonded in the state that extends at elastic webbing 6 under the situation at center of the central space 4 that the bonding wire 12a by eclipsed adhesive sheet 1 forms, be subjected to the part of elastic force when extending owing to the bonding process that connects splicing tape 5, be that boundary portion 3 is fixed by pressue device 7 pushings of high-frequency work metal die 8, bonding by fusion then, pass through cooling procedure again, product does not have defective fully thus.

In addition because the shape of wrinkle band forms central part than two side ends relative expansion; owing to air inject make that band extends up and down the time; the blank 18 that the phenomenon that the upper and lower side edge curls backward also produces because peripheral end 15 is fixing to the cut 14 and long-time foreign body sensation that can not feel fully that also the protective lining wing 16 produces that uses does not take place.
