Description

Unrolling strips

Technical field

The bar (strip) that the present invention relates to roll with roll-up device by tractive launches tube.

Background technology

External urinary catheter also claims urisheath (urisheaths) to be generally used for catheter assembly, with man who helps urinary incontinence and treatment and the surgery aspect that is used for hospital's disorder of urethra.This external urinary catheter generally includes the sheath or the main part of surrounding body of penis, and the tip portion that is provided with shorter discharge pipe, and this discharge pipe is connected to urine collection bag via pipe, and this urine collection bag for example is fastened on the lower limb of bed or user.Correctly launching sheath on penis may be very difficult.This operation is often undertaken by dexterous inadequately user or the personnel that have on the hospital of protective gloves for hygienic reason.Yet importantly sheath will correctly be installed, to guarantee leakproof seal between skin and sheath.If, will go wrong if sheath does not launch equably or protective gloves clings the sheath binding agent.

To the present a solution of this problem is single that sheath is used in help.Yet this is only at a side tractive of sheath, this can cause uneven roll and be difficult to hold by dexterous inadequately people.

The glove that are used for gnotobasis have run into the expansion problems of same type, and the glove top priority that promptly is applied to hands under the situation that does not contact glove is the aseptic that keeps glove.Therefore, need to improve correct unfolded instrument.

A kind of trial that improves expansion mode is disclosed among the DE 1 026 044, and the document has been described a kind of ducted body, particularly condom, and here, two ends of band (string) are rolled with condom.So can be by unfolded condom being placed on the penis and this band of tractive and condom is twisted on the penis.

Another similar a little solution is provided among the FR 2 649 315, the document is also described a kind of flexible condom that launches band that has, here, two end is rolled with condom and is pulled when condom is deployed on the penis at production period.

In addition, US 4,972, and 850 disclose a kind of contraceptive device without hands, and wherein, the condom with part of rolling is provided with a pair of.This has enough big width, so that make the turned up portion of condom present the configuration that length-width ratio is at least 1.2 ordinary elliptical, thereby prevents the early deployment and the entanglement of condom, may this thing happens when condom is partly rolled too early.

Summary of the invention

The solution of the problems referred to above is elements that thin material constitutes, and this element allows that its at least two length extend along the both sides of sheath in a parallel manner.Two length of this element are rolled with sheath.This element forms a ring towards the top at sheath tip, and this ring has enough big, so that can use man's thumb grasping and tractive.When moving downward this ring of tractive, sheath is unfolded.

Utilize double action strip, sheath just more easily is deployed on the penis in even mode and needn't contact adhesive.

Open in detail

Therefore, the present invention relates to a kind of device with rolled tubular section, this tubular portion comprises at least two bars of rolling with tubular portion, these edges along deployment tube separate each other suitably apart from placing, so that guarantee to launch along the edge of pipe, its mode be when tractive these the time make this pipe can be with uniform formal expansion.

The invention particularly relates to a kind of device, wherein, at least one zone of tubular portion is provided with binding agent, and when rolling, and at least a portion at least one of this at least one zone and two bars contacts.

Basic problem solved by the invention is that at this moment tube can launch equably by the tractive bar.In addition, do not need contact device.When being deployed in inside and having the urisheath of binding agent, this particular importance, because the nurse has gloves on usually, these glove certainly will cling the binding agent on the urisheath.

On the other hand, the desirable glove down of nurse, so that launch urisheath, this is convenient to the application of urisheath.Yet, increased the danger of infecting like this, also invaded patient and nurse's privacy simultaneously.Therefore, by providing a kind of according to device of the present invention, the nurse can avoid contacting urisheath and to the binding agent of this application, keep simultaneously having gloves on, thereby keep intercepting dirt and protection patient privacy.

Advantageously, bar can separate each other suitably apart from placing.This suitable distance is used the number of degrees regulation of bar along the edge placement usually, and calculates divided by the quantity of bar by the measurement number of degrees with the edge, and the measurement number of degrees at this edge are generally 360 °, and are corresponding with the number of degrees of circle.Therefore, if use two bars, the suitable distance that can calculate between two bars is 180 °, and if use three bars, then suitably distance will be 120 °.

In one embodiment of the invention, at least two bars are connected in the outside of the tubular portion of rolling.This is for the invention provides a major advantage: for example, at this moment Ling Qiao urisheath user can make and oneself only use a hands just to use urisheath inadequately, and not need outside help.This is the breakthrough to the self-respect of these user.In another embodiment, connection strap has formed the handle that is used to launch rolled tubular section.Also have among the another one embodiment, connection strap forms finger-pull-hole.This finger-pull-hole makes that for example the user of urisheath can insert finger and tractive.Although ear handle needs two fingers and the power between them, (tweezers clamping), ring only needs a pulling force.

Of the present invention one typical aspect in, tubular portion is outwards rolled.This is the traditional form of condom and urisheath for example.

Yet in a special embodiment, tubular portion is inwardly rolled.In the present embodiment, preferably, bar is drawn out from the tubular portion of rolling, and thus, allows that the inside outwards turns out.

Device with a kind of type of population of rolled tubular section is to need the used bag of compressed thing.In other words, this bag has the volume that roughly is fit to the compressed content thing.An one example is to be selected from the device that comprises bivouac sack and sleeping bag covering and so on.After rolling sleeping bag, the sleeping bag covering of rolling is placed the end of the sleeping bag of rolling.Obducent at least two bars of tractive sleeping bag will be deployed in the sleeping bag covering on the sleeping bag, and will compress sleeping bag simultaneously.The same applies to bivouac sack and other this similar device.

The type of population device that another kind has rolled tubular section is to have flexible/elastic, the strict device that is fit to some thing.This device has the ball of the intended contents of being slightly less than, but because the flexibility and/or the elasticity of material, it will be suitable for content.An one example is to be selected from the device that comprises socks, stocking, condom and urisheath and so on.For example when foot was arranged, the socks of rolling were placed in the tip of toe.At least two bars of this of tractive socks will be deployed into socks on the foot.The material flexibility of socks will guarantee to be held in place after socks are placed.The same applies to condom, urisheath and other this similar device.

Device with a kind of special type of population of rolled tubular section and at least two bars is at application, expansion and/or the device that should not be touched between the operating period.An example of this device is the device that is used for sterile procedures, such as aseptic glove.Roll the sterile gloves that has at least two bars and can use glove in the following manner, promptly a hands is put into the glove of rolling, two bars of reuse another hands tractive, or be placed on the handle of two bars on the rod shaped structure and promote glove.Therefore, glove are placed on hand and not and are in contact with it.Similarly, opposite with common manual expansion, use the urisheath that has two bars by these two bars of tractive.Therefore reach, in the time of on being applied to penis, can not contact urisheath, more particularly, can contact adhesive.This not only will guarantee the optimal adhesion to penis, and also alleviate the problem that the nurse stands during using when nurse's glove adhere to urisheath.

In one aspect of the invention, preferably, tubular portion is a thin-walled.

The bar that is used for urisheath does not have again by obtaining required power that material extends or the required minimum material of breaking is made, and is preferably made by polyethylene.

Because sheath comprises adhesive layer, bar preferably includes adherent layer, to avoid adhering to the adhesive layer on the urisheath inside.

In order to obtain bar urisheath is deployed into estimated performance on the penis, must uses the sheath binding agent is had enough strip materials of antiseized ability.An embodiment of strip material can be the polyolefin film such as the polyethylene that scribbles silicone or polypropylene and so on, and the separation value of itself and urisheath is the 20-30 dyne.In some cases, when the selection of material and binding agent is allowed, the polyolefin film with not band coating of higher separation value will reach enough and separating power binding agent, so that sheath is launched.

Be appreciated that the different materials that is used for the used separating underlay of urisheath and bar can reach different dyne values.Yet, under unqualified situation of the present invention, can be understood as usually, the strip material that the separating force that seldom uses with urisheath is had the dyne value more than 50 dyne will be because this will can produce excessive traction force during using urisheath.Therefore, in one embodiment of the invention, the dyne value in tubular portion and at least two bars between each is between the 15-50 dyne, particularly between the 20-40 dyne, especially between the 20-30 dyne.

When the tubular portion that preparation is rolled, this will be used with unfolded state usually.After this, tubular portion is rolled-up, makes this be placed between the inside and outside of pipe.Thus, each bar forms the path along tubular portion.

In one embodiment, each all is parallel to the longitudinal axis that launches tubular portion in those paths, therefore guarantees to stretch uniformly.

Yet when placement is parallel to the bar of the longitudinal axis of deploying portion, the tubular portion of rolling will have uneven outward flange, and bar is thick more, does not have the place along the edge of bar thin more.In order to obtain the more level and smooth surface of rolled tubular section, at least one path of bar is spiral-shaped.

The exact position of each bar, the length of extending in the outside of rolled tubular section and their optional junction point depend on several factors.Schemes more described below will illustrate this point:

In the obducent design of sleeping bag, for guaranteeing the required power of compression sleeping bag during launching the sleeping bag covering, three and even four or five bars will be considered to be fit to.Launch for the enough compressions that guarantee material very important uniformly.In this case, bar will be connected to pipe in the heart, promptly sleeping bag obducent in the heart.In three bars each will be evenly spaced apart along the edge of rolled tube, promptly 0 ° (for example vertically to the right), 120 ° and 240 ° locate.Each bar will be placed along the edge of rolled tube equally equably, promptly locates at 0 °, 90 °, 180 ° and 270 °.In use, the sleeping bag of rolling is placed in the inside of bar net and rolls on the sleeping bag covering.Facing to the sleeping bag covering promote sleeping bag and simultaneously the tractive bar will be on sleeping bag expansion sleeping bag covering.

Usually, in the design of urisheath, two bars are just enough.Balance between the importance that the production complexity that the quantity basis of bar is evenly rolled and is increased is offseted and the probability of bar entanglement is during use determined.In this case, bar connects along the edge of turned up portion.Taking this point on the edge is 0 °, article one is placed-90 ° locate, and second is placed+90 degree places, utilizes same long bar to divide cloth equably along the edge thus.Yet, in another embodiment, connecting part at bar, handle is not positioned at the center between 2.Therefore, article one is placed in 0 ° and locates, and another is placed in 180 ° and locates, so the part that article one is extended in the tube outside of rolling is shorter than the part that second extends in the tube outside of rolling.When (article one, second) position is following everywhere the time, similarly consider also to be suitable for, these positions comprise: (2 °, 178 °), (4 °, 176 °), (6 °, 174 °), (8 °, 172 °), (10 °, 170 °), (12 °, 168 °), (14 °, 166 °), (16 °, 164 °), (18 °, 162 °), (20 °, 160 °), (22 °, 158 °), (24 °, 156 °), (26 °, 154 °), (28 °, 152 °), (30 °, 150 °), (32 °, 148 °), (34 °, 146 °), (36 °, 144 °), (38 °, 142 °), (40 °, 140 °), (42 °, 138 °), (44 °, 136 °), (46 °, 134 °), (48 °, 132 °), (50 °, 130 °), (52 °, 128 °), (54 °, 126 °), (56 °, 124 °), (58 °, 122 °), (60 °, 120 °), (62 °, 118 °), (64 °, 116 °), (66 °, 114 °), (68 °, 112 °), (70 °, 110 °), (72 °, 108 °), (74 °, 106 °), (76 °, 104 °), (78 °, 102 °), (80 °, 100 °), (82 °, 98 °), (84 °, 96 °), (86 °, 94 °), (88 °, 92 °), (90 °, 90 °), (92 °, 88 °), (94 °, 86 °), (96 °, 84 °), (98 °, 82 °), (100 °, 80 °), (102 °, 78 °), (104 °, 76 °), (106 °, 74 °), (108 °, 72 °), (110 °, 70 °), (112 °, 68 °), (114 °, 66 °), (116 °, 64 °), (118 °, 62 °), (120 °, 60 °), (122 °, 58 °), (124 °, 56 °), (126 °, 54 °), (128 °, 52 °), (130 °, 50 °), (132 °, 48 °), (134 °, 46 °), (136 °, 44 °), (138 °, 42 °), (140 °, 40 °), (142 °, 38 °), (144 °, 36 °), (146 °, 34 °), (148 °, 32 °), (150 °, 30 °), (152 °, 28 °), (154 °, 26 °), (156 °, 24 °), (158 °, 22 °), (160 °, 20 °), (162 °, 18 °), (164 °, 16 °), (166 °, 14 °), (168 °, 12 °), (170 °, 10 °), (172 °, 8 °), (174 °, 6 °), (176 °, 4 °), (178 °, 2 °), or (180 °, 0 °).

Should be pointed out that and not require that bar distributes equably along the edge of tube.For example, if the barrier that bar to be ready connecting through the past is from the diagonal side, and the words that the hardness of tubular portion material is allowed, bar separates with the angle less than 180 °, such as 178 °, 176 °, 174 °, 172 °, 170 °, 168 °, 166 °, 164 °, 162 °, 160 °, 158 °, 156 °, 154 °, 152 °, 150 °, 148 °, 146 °, 144 °, 142 °, 140 °, 138 °, 136 °, 134 °, 132 °, 130 °, 128 °, 126 °, 124 °, 122 °, 120 °, 118 °, 116 °, 114 °, 112 °, 110 °, 108 °, 106 °, 104 °, 102 °, 100 °, 98 °, 96 °, 94 °, 92 °, 90 °, 88 °, 86 °, 84 °, 82 °, and even 80 °.

When using three or more bars, same consideration also is suitable for.

The manufacturing of tubular portion as herein described is very simple usually.It may further comprise the steps:

(a) added at least two bars before rolling, described at least two bars are apart suitable distance along the edge of pipe.

(b) rolled tubular section, its mode are to make described to roll with tubular portion.

Equally, a kind of method that is used to launch have the device of rolled tubular section, this tubular portion comprises at least two bars of rolling with tubular portion, the distance that it is suitable that these edges along deployment tube separate each other is placed, so that assurance launches along the edge of pipe in the following manner, that is, these comprise to be parallel to away from the longitudinal axis at tip and in the position of rolled tubular section during perpendicular to described of the angle tractive between the longitudinal axis when tractive, make this pipe can be with uniform formal expansion.
