DESCRIPTION:

BRIEF SUMMARY
The invention relates to a tampon or closure device for insertion into externally debouching, artificial or natural body canals of animal or human beings and comprising an resilient compressible plug-like body of moulded material, which body when inserted is expanded to a cross-sectional dimension ensuring closure of the body cavity (canal) in question, and which body for use at withdrawal from the body canal is provided with a handle means protruding from the body and being in connection with an anchor part encapsulated in the body with a relatively large bearing face against the surrounding moulded material and made from a material with a knitted structure providing for a three-dimensional bond to the moulded material.
In GB patent no. 788,407, GB patent application no. 2,153,686 and the U.S. Pat. Nos. 1,561,020, 1,731,665, 3,520,302, 3,916,898 and 4,979,947, among others, are disclosed various forms of tampons for placement in externally debouching body canals, eg. vagina or anus, for absorption of fluids and/or for medication.
From the mentioned publications is further known to provide devices of this type with a protruding handling means for use at withdrawal from the body canal in question, most frequently being in the form of a cord fastened to the tampon and extending in the longitudinal direction hereof.
By way of example, from GB patent application no. 2,153,686 and the U.S. Pat. Nos. 3,916,898 and 4,979,947 is it known to design devices of the type in question from a spongy or plastic foam material, eg. polyurethane foam, and having a handle means in the form of a relatively thin cord or string, eg. from a monofilament material which is lead through the material, maybe in the form of a loop.
Since such a cord or string must per se have sufficiently strength in order not to break during the withdrawal, it has, however, appeared that in connection with tampons of plastic foam material which in the expanded state may be relatively weak, there is a considerable risk that the cord is pulled out of the tampon or the closure device without it following or the material breaking such that a part of the closure device remains in the body canal in question and thus may constitute a considerable risk of infection.
From international patent application WO 88/05294 is known an anal plug of the initially indicated type and made from plastic foam material, where a protruding handle cord is connected with a separate disc-shaped intermediate piece disposed across the longitudinal direction of the device.
The intermediate piece may be of a perforated or knitted tissue with cords fastened to a rigid anchor part which is anchored in the tissue. In this known device the anchoring device thus comprises several parts which makes the plug complicated and dearer.
For a tampon or closure device of the indicated type, the above stated drawbacks are avoided according to the invention in the way that the anchor part is designed as a stocking-like element orientated in the longitudinal direction of the plug-like body and is in integrated connection with a handle means.
Besides, a processing step is saved, the withdrawal device being encapsulated at the same time as the moulding of plugs contrary to conventional manufacture where the withdrawal device is not fastened to the plug until this is moulded.
As a consequence of the relatively large bearing face and the three-dimensional bond to the moulded material in the plug-like body, it has even by manufacture hereof from a relatively weak or brittle material proved to be possible to obtain such a secure attachment of the handle means that the risk of tearing the closure device during withdrawal is eliminated or at least reduced considerably.
The anchor part may be manufactured from a soft flexible material, eg. in the form of relatively fine-meshed netting. A preferred embodiment is characterized in that the anchor part is designed as a relatively short element of woven or non-woven material, preferably fabric or plastic, eg. gauze.
The manufacture can be expedient in that one e
