Description
~2~7~3 A device for sterilizing ducts and connec~ion elements between two containers for the effusion of sterilized liquids The present invention concerns a device for sterilizing, by means of a disinfectant, ducts and connection elements used between two containers for the effusion, from one to the other, of sterilized liquid, maintaining the original sterilization thereof.
The problem of the sterilization of the ducts ancl of ~he connection elements placed between two containers for the eEfusion of sterilized liquids, is of enormous importance, because the alteration of the original sterilization may cause the development of bacteria or similar which in turn may provoke serious infections in those who use said liquids, which are particularly used in medical fieldsO
One of the possible fields in which it may result to be extremely important to guarantee a perfect sterilization is the continuous ambulatorial peritonaeum dialysis (CAPD3.
It is already well known that the peritonaeum dialysis is a technique used to free the patient's organism from toxic substances it may have accumulated Eor different reasons:
mainly the insufficient Eunctioning of the kidneys.
~lr~
~2~ 3 Said technique consists in introducing into the abdominal cavity a solu~ion of appropriate composition and quantity and taking it of~ after said solution has absorbed the toxic substances to be eliminated by means oÇ diffusion with the blood ~hrough the peritonaeum membrane and the internal organs comprised therein.
The purification cycle must be repeated in proportion to the need for cleaning shown by the single patient.
The main application limit of said therapeutic technique -which is easy to perform and rather efficacious - is given by the high number of peritonitis which it causes due to the introduction of germs into the abdominal cavity by the eventual infection at the connection point between the solution defluction tube and the catheter leading the solution into the abdomen.
This kind of inconvenience happens with a particular frequency in the use of the new continuous ambulatorial peritonaeum dialysis (CAPD~, due to the high connection number between the catheter and the container of the solution requested by this technique.
Various systems have been tcied to eliminate the latent dangers of infections, comprising the one suggested by 0~3 Oreopulos and the one called "Perugia CAPD System. n Even if, by use of these systems, the number of peritonitis cases has been rather reduced, this kind of infection heavily weighs on said technique and limits the use thereof.
It is the aim of the present invention to allow a perfect sterilization of any system of sterilized li~uid effusion, with a particular attention to the application thereof to the continuous ambulatorial peritonaeum dialysis.
In one aspect, the invention consists of a circuit for transferring sterile fluids between a container and a receiver comprising: a first duct having a first end for receiving fluid from the container and having a second end;
a sterilization chamber having a first opening adapted to rec~ive said econd end of said first duct therethrough and having a second opening; a second duct having a first end adapted to be received by said second opening of said chamber and to thereby communicate with said first duct within said chamber, and having a second end adapted Eor communication with the receiver; a third duct selectively communicating with said second duct for introducing a disinfectant solution to fill said circuit and discharging the disinfectant from said circuit; valving means for selectively introducing the disinfectant into said circuit through said third duct to fill the circuit, for introducing ~2Z7~3 the sterile fluid into the circuit to flush the disinfectant out of the circuit and for conducting the sterile fluid to the receiver through said first and second ducts.
In another aspect, the invention consists of a circuit for the sterilization of ducts and the connective elements between a container and a receiver for the effusion of sterilized liquids therebetween comprising: a first duct having a first end connected to the container and having a second end; a chamber having Eirst and second openings; a valve member including first and second valve halves hingedly connected together and capable of assuming a closed position in which said valve member has a groove therein and an open position, said valve in said open position adapted to receive said second end of said first duct within said groove, said valve in said closed position adapted to retain said second end of said first duct in said groove and further adapted for insertion into said first opening of said chamber to permit liquid ~low between the in~erior of said chamber and the container connected to said first duct; a second duct having a first end received by said second openinq of said chamber and having a second end adapted for connection to the receiver, said irst end of said second duct including a perforating member movable between a non-operative position and an operati~e position, said second end of said ~irst duct further being closed by a membrane capable of being ~270~3 - 4a -perforated by said perforating member to connect said first and second ducts within said chamber when said perforating member is moved to said operative position; a connector member; a third duct, having a first end connected to said S second duct through said connector member; a four~h duct having a first end connected to said chamber for conducting air out of said chamber; a first valve for opening or closing said fourth duct; a second valve for opening or closing said third duct; and a third valve for opening or closing said second duct.

According to the present invention and provided that a sterilized liquid shall be effused from container X to container Y, also sterilized, and so as to avoid the contamination of said liquid, thP following steps must be followed:
1) ducts A and A' shall be fixed to respective steri lization chambers C and C', so that ends B and B' may project inside said chambers;
2) provided that chambers C and C "lre permanently connected to respective ducts E and E', said cham bers will be fixed in a vertical position so that B and B' are placed in the high part;
3) by means of devices I, I', L and M the ducts, on ~5 which said devices are placed, will be opened;
4) through duct F the sterilization substance will be introduced up to a level to cover B and B', avoid in~ the forming ofair bubbles in the whole trans~er 7~1~L3 circuit, comprising chambers C and C' (the air will find an outlet through G and G') and then L

fected, so that the connection between A and E can also be performed;
6) L will be opened and the sterilized liquid contain ed in X will flow down to effect the washing of ducts E and F so as to totally expell the steriliz ing substance; when this is done, L will be clos=
ed and M opened; now the sterilized liquid will flow through the other branch of the circuit, ex=
pelling the sterilization substance from E~ and C~
through G' and effecting the necessary washing: at this point B' and D' are connected.
With this last operation containers X and Y are plac led in communication and the effusion of the liquid can be performed, maintaining the original steriliza tion.
For what concerns the application of the present in=
vention in the continuous ambulatorial peritonaeum dialysis, according to ~igures 2, 3 and 4~ the device comprises the use of only one part of the scheme of figure 1 t as container Y is now replaced by the abdo minal cavity and therefore all that part shown by E~, D', C', Bl, A', G', I' and Y will be eliminated.
Furthermore, branch H of Figure 1 must be replaced by a three-way connection which, beyond connecting ducts E and F, shows a third way for the closing with a cap or as well or the connection with duct O, provided with device M and placed like a prosthesis onto the catheter and with the free end for the closing thereof with a cap or for the connection with the three-way connection; further, the addition of closing and opening device N is provided.
Referring to the details o another embodiment according to Figures 2, 3 and 4, they show:
- device P ~or coupling A with C, autostopping due to its conicity, consisting in two valves V united by a hinge;
said device, when extracted from the seat, can be opened and duct A can be introduced into the groove thereof;
- the closing of duct A, consisting in perforable membrane K
placed, like a hat, on end 8 of said duct;
- the main body of the whole device, consisting in transparent material, having a longitudinal cavity and provided, at one side, for the coupling and locking with P, while on the other side the per~orating connector, coaxial to duct A contained in .,, ~Z27~3 -- 8 -- .
P, is placed, in the central part of said main bo dy remains a free space 9 corresponding to the ste rilization chamber;
- perforating connector D sliding in the main body and perfectly tight wit~ respect to the same; a projection of said connector to which duct E is connected is of such dimension and rOrm that it can be handled from outside.
For what concerns the functioning of the invention in the embodiment for the continuous ambulatorial pe ritonaeum dialysis (some days after placing of the catheter in the abdominal cavity, when the abdomen of the patient is full with solution), prothesis 0 will be c~nnected to the catheter, said prothesis carrying a cap at the opposite end and with closing system M locked.
Once removed the cap from the free end of the prothe sis, the same will be filled up with the disinfectan~
and then closed again. The fresh solution poc~et is then connected to the trans~er circuit by introduc=
ing the end part of duct A into the valve coupling device P pocket, which in turn will be introduced in to the apposite seat of the upper part of the main body containing the sterilization chamber C.
Further, the free end of the prothesis will be con=
~;27~L3 g nected to the third way of connection H of the transfer circuit. Once L is opened through F, the circuit gets filled up with disinfectant, taking great care in elimin-ating the air bubbles from connection H as well as from the sterilization chamber, making them flow down through duct G.
Now L is closed and it is attended until the disinfectant has performed its action. Then ducts A are connected and membrane B is perforated by the advancing of point D. Once L has been opened a certain amount of fresh solution is made to flow down, thus washing the whole circuit removing the disinfectant contained therein.
After a determined quantity of solution has washed the circuit (about 100 ml.), N is closed, M is opened and the solution contained in the abdomen and which is now saturated with toxins from the blood, flows down.
The outflow of said solution has also the task of completely removing the disin~ectant from prosthesis O.
Once the outflow from the abdomen has ended, N will be opened again and L closed, thus filling up the abdomen with the fresh solution. Once the Eilling up is ended, M closes the inlet to the peritonaeum cavity and a~ter L is opened, 27C)13 the transfer circuit will be filled up with the disinfectant until it has filled the pocket outflow of duct A.
The same duct will be closed by the system of tightening the tubes and th~ duct will be cut above the closing. When L
and N are also closed r prosthesis O will be detached from connection H, which will be closed with the apposite cap.
Now prosthesis O will be filled up with the disinfectant finally, the inlet to O will be closed with the apposite cap and the patient can freely move about until the next effusion, without any limitation and without any need of carrying along the transfer set and the usually used pocket and, furthermore, the prosthesis will be always protected by the disinfectant.
At the time of the following effusion it will be sufficient, as the prosthesis is already placed and full of disinfectant, to repeat the cycle.
