DEVICE FOR THE INTERNAL CLEANING ~ND CLEARING OF TUBULAR
BODIES FOR MEDICAL USE WHICH ARE INSERTABLE IN HUMAN ~ODIES
Technical Field The present invention relates to a de~ice for the internal cleaning and clearing of tubular bodies for medical use which are insertable in human bodies, particularly endotracheal tubes, drainage tubes, uxethral probes and 5 catheters, and tAe like~
:: Background Art : As is known,: endotracheal tubes are substantially constituted by a tuhular portion having, at its outward end, means for connection for example to the respirator and, proximate ~to its inward~end, a~ membrane which can be infIated by means of a~tube connected to the outside; this membrane in practice lo ates the inward end of the tube and creates, so to speak,~the outward seal with regard to the inspired and expired air.
::It has ~e~n o~fserved that in patients intu~a~ed even 1;5~ for a~short time ~he endotra~hea1 tubes tend to clog due to :: the: more ~r less dense secretions which d~posit inside the `:. tubes~
;:: ,; . ~: ~ ;
Deposition of the secretion within the endotracheal tuba causes an immediate increase in inspiratory and -.
expiratory~ resistances, due to the narrowing of the useful flow~saction~
The soIutions~currently adopted to rastore the useful , :
:flow section are in ~practice con tituted by swab-like ',~
elements which are~inserted in the endotracheal tu~e to ,~
25: remove the secretions present on the walls.

, W094/03~26 21 1 0 a ~ ~ PCT/EP93/020r,~-patient 9 since during the insertion of the swab-like element most of the secretions are pushed toward the inside of the patient's trachea.
Th~refore, in many cases it i5 necessary to replace the endotracheal tube, performing ~xtubation of the patient and subsequent re-intu~ation thereof with a fresh tube; this , operation first of aIl requires the presence of a physician and is furthermore not pleasant for the patient.
Disclosure of the Invention The aim of the:present invention is indeed to solve the problem described above by providing a device for the int~rnal cleaning and clearing of tubular bodies for medical use to be inserted in human bodies, particularly but not exclusively for endotracheal t~bes, which allows to remove :~ : even the densest and hardest secretions pre~ent on the : ~
~ 15 internal walls of the tubular body rapidly and simply ~, without~ external contaminatlons and most of all avoiding ; extubation of: the:patient.
Wi~hin the scope of ~he above aim, a parti ular object :~ o~ the present invention is ~o provide a cleaning device :~
~ 2Q which is in practice constitu~ed by a disposable kit which .
allows ~o operate inside the tu~be without sending s~cretions oward the patient during insertion.

;~ :;Ways of carrying out the Invention ~
~ 15With re~erence~ to the~above figures, the device.
:`~ according to the:pres~nt inven~isn is particularly but not exclusively u able for~ cleaning an endo~racheal t ~e, generally designated~ by the reference numeral 1, whioh comprises a tubular element 2,~preferably made of a plastic mate~ial suitable for u e in the medical field. The tub~lar ~ ~ .
: element 2 has; at its inward~end, an oblique cut 3 arranged :in place inside the trachea.
On the outside of the:t~bular element 2, proximat to the inward end 3, there is~a membrane 4 which can be - . ., 25~ inflated to perform positioning and sealing; said me~brane .-is~ connected~, in ~a ;per se:known manner, to a tube 6 pro~ ~ ding outwardly. :
~, At~ îts ~utwaxd~upper end, the tubular elemen~ 2 is connected to a connector 10 provided with a branching 11 for SUB~3TITUTE ~;HEET
214~28 ~ ~
1 ~094/03226 PCT/EP93/02009 connection to a respirator.
The device according to the present inve~tion, generally designated by the reference numeral 20, comprises a relatively flexible inner rod 21 slidingly accommodated 5 within an outer sheath 22 which is also relati~ely flexible~
The inner rod is provided with a grip eyelet 23, whereas the outer sheath is provided with a handgrip 2~
which eases ~he movement of the the inner rod with respect to the outer sheath.~
~; 10A cleaning element, generally designated by the reference numeral 30 J is provided at the inward end and is : advantageously constituted by a cylindrical tu~ular braiding : ~ :
~: ~ :31 made from interwoven wires and connected, at its axial ends,~ respectively;to a tip 35 o~ the:inner rod 21 and to :15 the inwar~d end 36 of the shea~h 22.~
Relatiwe ~sli:ding between the inner rod and the sheath causes,:~as schematically shown~ in figure 6, an axial compression on~the interwoven-wire braiding, which can be made `~rom~ wires` made of metallic or plastic fibers and undergoes a:: radia~l expansion which can ~e: contrslled as required depending on the relati~e sliding between the inner rod and~: the shæath>~
In practice, :the expanslon of the cylindrical braiding 31 is proportional, i D e . ~allows use on tubes h~ving 25:~different :: dimensions, since the braidin~ can expand i-radially, until~ it~adheræs to ~he walls, simply by increasing axial compres~ion, i.2. the relative slidiny between the inner rod and the shea~h.
: The :device according to the present invention is ~`:: : 30 insertable in the inlet 12 of the connector 10, as shown, , , W O 94/03226 2 14 ~ 5 2 ~ PCT/EP93/020~
but can also be inserted directly on the outward end of an endotracheal tube which is not provided with said connector 1~ . .
Advantageously, for hygienic reasons, the devicQ
according to the present invention furthermore comprises a tubular bag 40 which is applied at the end of the inlet 12 or directly to the outward end of the endotracheal tube and in practice surrounds the sheath, actin~ as element for ~: coIlecting:the secretions which accumulate in the ext~ndable lo bag withou~ o~tward loss~
The tubular bag is capable of collecting any secretions which separate from the inside of the endotracheal tube and :
allows to ~void direct contact wi h the secretions, reducing the possibility o~ cross-infections, and furthermore allows ;15 ~o keep the cleaning element clean, said cleaning element is inserted in the endo~racheal t ~ e without environmental contau~inations~
In practical use, the first operation which is per~oxlmed is: the c~nnection of the tubular bag to the inlPt - 12 o the connector 10 or directly to the outward end of an :
: endotracheal tuibe not provided~ with said connector. Then the ; assen~bly constituted by the lnner rod 21, by the outer sheath ~2 and by the cleaning element 30 is inserted in the sndotracheal tu~e with the cylindrical braiding 31 in contracted position, and insertion is perforlmed uLntil the tip 35 `reaches the lQwer end of the tu~Dular element 2, Once the device has been positioned, relati~e sliding between the inner rod and the outer sheath is perfor~d by sliding ~he ou~er sh2ath on the inner rod in order to produce a radial è~?ansion of the braiding 31 which EET
214~528 ~
! iVO 94/Q3226 PCT/EP93/0200~
7 .
constitutes the cleaning element. By virtue of this expansion, the internal braiding rests on the internal wall of the endotracheal tube.
Onc~ the cleaning element has been positioned, it is sufficient to extract the cleaning element ~rom the endotracheal tube, sliding it upwards, so that any secreti~ons are completely removed from the inside of the tubular element and are collected in the tubular bag 40.
: ~Once the extractio~ has ended, the tubular bag is disconnected and the entlre unit is discarded; the int~rnal walls are cleaned without introducing the secretions inside the patient, by virtue of the fact that a device, having a cleaning:elem~nt:which is ins rted in a radially contracted position and can be expanded radially once it has been ~: 15 correctly positioned at the lower end of the endotracheal ~: ~tube, is used.
:From the above de:scription:lt can thus be seen that the :
. .
present in~ent:ion achieves th~intended aim and objects. In : particular,: attention is drawn to the constructi~e ZO simplicity of the de~ice, which arises from the fact that the relative sliding of two structurally simple elements, :such as ~he inner rod and~ the outer sheath, mutually connected by a cylindrical braiding obtained with interwoven wires ~hich expand radlally, is used to expand the cle ning element~
Although the de~ice according to the present invention has be n conceived particularly for cleaning endotracheal : t~bes, ~it can be, in any case, used for cleaning and clearing other tubular bodies for medical use in general, 30 ~which are insertahle in the human body~ such as for example ~, ~ SUBSTITUTE SHEET
W094/03226 214 ~ S 2 8 PCr/EP93/020~
drainage tubes, urethral catheters and probes, or the like.
The invention thus conceived is susceptible to numerous modi~ications and variations, all of which are within the scope of the inventive concept; all the details may : ~5 furthermore be replaced with other technically equivalent elements.
: In practice, the materials employed, so long as they are compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to the requirements.
Where technical features mentioned in any claim are followed by ref2rence signs, ~hose reference signs have been included ~or: : the sole~ purpose of increasing the intelligibility of the claims and accordingly such r2ference signs ~do not have any limiting e~fect on ~he scope of each : element identified by way of example by such reference ; signs. : ~
