Description

The present invention relates to a probe

  weighted for enteral feeding.

  To achieve long-term enteral feeding, a probe made of a very flexible tube is generally made of silicone. Such probes, however, have the major disadvantage of being difficult

  to put in place because of their great flexibility.

  To avoid such a disadvantage, it has already been proposed to introduce a mandrel into the probe, but this mandrel is sometimes difficult to remove because of

  the sticky surface state of the silicone.

  It has also been proposed to ballast the distal end of the probe, either by means of an inner or outer olive, or by means of a charge of mercury.

housed in the probe tube.

  This technique of ballasting by means of a

  mercury charge ensures a natural training

  rel of the probe, since the weight of mercury ensures the best weight / volume combination while keeping

the probe some flexibility.

  The known method for ballasting such a probe by means of a charge of mercury consists in plugging the distal end of the probe tube with a silicone-based adhesive, then charging the mercury with the aid of a a syringe and a needle through an orifice

  in the probe tube near the end of the

  distal mass, and to inject through this same hole a plug of glue intended to-position the load of

  mercury inside the probe tube.

  Such a process, however, has a disadvantage

  because it is very difficult to purge the air when the mercury charge is injected into the probe tube and when the second

  glue intended to trap the charge of mercury. -

  Accordingly, one of the aims of the invention

  is to make a weighted probe for feed-

  rale, of the type comprising a flexible tube, for example silicone, whose distal end is weighted by means of a load of mercury, which avoids the disadvantage cited

  previously allowing air to escape without difficulty.

  during the introduction of the mercury charge

inside the probe tube.

  For this, the present invention proposes a

  weighted probe of the type described above which is

  the fact that the mercury charge is introduced

  in a closed cartridge that is put in place

  inside the distal end of the probe tube.

  According to another characteristic of the invention, this cartridge is made from a tube in

  thermoplastic material, for example in poly-

vinyl chloride.

  It is then possible to make such a cartridge by cutting the tube to form the cartridge to the appropriate length, by heating one end of the tube section thus obtained by heating, by introducing the charge of mercury by means of the other end of the tube section. needle or syringe and closing with

heating this other end.

  According to another characteristic of the invention,

  the cartridge filled with mercury is kept in the ex-

  distal end of the probe tube between two corks

glue.

  Other features and advantages of the invention will be better understood when reading the

  detailed description which will follow and which refers to

  attached drawings, given purely by way of illustrative example, and in which: - Figure 1 shows a section of the distal end of a conventional probe with a charge of mercury; - Figure 2 shows a section of a cartridge filled with mercury, intended to equip a probe according to the invention; and FIG. 3 represents an elevational view with partial section of a probe according to the invention, the distal end of which is weighted by means of the cartridge.

  Reference will now be made to FIG. 1 to describe a probe for enteral feeding, the distal end of which is weighted by means of a loading charge.

  The probe partially shown in Figure 1 comprises a flexible tube 10, made for example of silicone, the distal end 12 is ballasted by means of a charge of mercury 14. To achieve such a ballast, it first closes the distal end 12 with a silicone-based glue for filling a stopper 16. The mercury is then loaded with a syringe and a needle through an orifice 18.

  fice a glue plug 20 for positioning the mercury charge within the distal end

of the probe tube.

  As indicated above, such a method has a major disadvantage because it is very difficult to purge air when injecting mercury and when making the second plug of glue

  (cap 20) trapping mercury.

  The weighted probe of the invention will now be described with reference to FIGS. 2 and 3. FIG. 2 shows a closed cartridge 22 filled with a mercury charge 24 intended to be placed in the distal end of a probe tube. To produce such a cartridge is advantageously used a thermoplastic tube, for example polyvinyl chloride, which is cut to the appropriate length. One end of the tube section obtained, for example the end 26, is then closed by heating this end. The mercury charge is then introduced through the opposite end, left open, using

  syringe and needle, positioning the needle

  guille in the bottom of the tube 22 so as to chase the air.

  The other end of the tube, for example the end 28, is then closed by heating. The cartridge filled with mercury thus obtained can then be introduced into

  the probe tube as shown in FIG.

  FIG. 3 represents a weighted probe for

  enteral feeding, performed according to the invention,

  taking a flexible tube 30 whose proximal end 32

  is provided with an appropriate connection 34 and whose

  The distal portion 36 is weighted by means of the cartridge 22 of FIG. 2. To carry out such a ballasting by means of the cartridge 22, this cartridge is first placed in the probe tube 30 by introducing it through the distal end. 36. This distal end is then closed with a silicone-based adhesive plug 38 and a second plug of adhesive is injected through an orifice 40 made in the probe tube near the distal end. 42 for positioning the cartridge

  22 inside the probe tube 30 between the two

plugs 38 and 42.

  The probe of the invention has all the

  advantages and the same applications as the conventional probes

  mercury ballasted, without the inconvenience of placing the load

of mercury.

  Of course, the invention is not limited

  at the time of realization specifically described and

  felt on the drawings and we can imagine others

  variants without going beyond the scope of the

vention.
