Abstract

The invention relates to a device for converting a fluid takeoff for medical use so as to fit it onto an existing fluid takeoff the front face of which includes a connection surface, for example two to five notches depending on the fluid, and which contains a valve the front end of which extends beyond the front end of the said takeoff. The device according to the invention is characterised in that it consists of a monobloc sleeve 8 the rear face 3 of which includes a surface which is complementary to the said connection surface, for example studs 4 which become housed in the notches 9 of the existing takeoff 18, the front face 1 of which is provided with radial notches 2 and lateral grooves 11 with a locking notch, the said sleeve 8 containing a valve 5 of standardised diameter provided with a filter 15, the rear end of the said valve 5 passing through the rear face 3 of the sleeve 8 to come into the vicinity of the front end of the valve 13 of the existing takeoff 18, the sleeve 8 further including a radial screw 7 interacting with a notch 9 in the existing takeoff 18 to prevent the sleeve 8 from rotating with respect to the existing takeoff 18. Application to the dispensing of medical fluids.

Description

Device for transforming a fluid intake for medical use.

The present invention relates to a device for transforming a fluid intake for medical use, in order to adapt this existing fluid intake to the security constraints imposed by use.

Existing fluid intakes do not have the required safety features. In particular, these existing sockets do not have a locking system for the plug or the appliance to be connected and only have a single valve, which means that the distribution networks must be cut off to ensure maintenance operations.

The present invention aims to make existing fluid intakes conform by # simple adaptation of a transformation device and to allow maintenance operations without general interruption of the supply networks.

To this end, the subject of the invention is a device for transforming a fluid intake for medical use in order to adapt it to an existing fluid intake, the front face of which has a connection surface, for example two to five notches. depending on the fluid, and which contains a valve whose front end projects beyond the front face of said socket, characterized in that it consists of a monobloc socket, the rear face of which has a surface complementary to said connection surface, for example nipples coming to be housed in the notches of the existing socket, the front face of which is provided with radial notches and lateral grooves with locking notches, said socket containing a valve of standardized diameter provided with a filter, the end rear of said valve crossing the rear face of the socket to come in the vicinity of the front end of the valve of the existing socket, the socket further comprising a radial screw cooperating with a notch the existing socket to prevent rotation of the socket relative to the existing socket.

Advantageously, the rear face of the socket -has a collar applied to the front seal of the existing socket. Preferably, the front face of the sleeve includes a removable shutter to ensure maintenance of the assembly.

In order to ensure the unity of the assembly after assembly, the invention provides that a bracket is tightened against the wall by a nut screwed onto the existing socket, said bracket carrying a housing closed on its front face by a cover. held by a nut screwed on the periphery of the socket.

The invention will be clearly understood on reading the following description made with reference to the accompanying drawings in which:
Figure 1 is a schematic perspective view of the
existing socket and device according to the invention, before
mounting; Figure 2 is a schematic perspective view-
ve from the front of the existing outlet; figure 3
is a schematic perspective view of the front face
the adaptation device according to the invention; figure 4
is a schematic view in axial section of the exis socket
aunt on which the adaptation device is fixed,
and Figure 5 is a schematic side elevation view
stripe, partially in section, of the set rises in a
wall and fitted with a housing.

The existing socket 18 is provided on its front face with two to five
notches according to the gas and is provided with a valve 13. It is mounted
on a brazing socket 24 (Figure 5) housed in the wall and connected to the distribution network 25.

The transformation or adaptation device according to the invention
is formed by a single-piece socket 8, the rear face of which is provided with two to five pins 4 cooperating, during assembly, with the notches
9 of the existing socket 18. The front face 1 of the socket 8 is
closed by a screwed shutter 12 and has two to five notches the
terals 2 of width and position suitable for the desired application, and as many lateral grooves 11 provided with a notch of worm for a device or a plug to be connected.

The socket 8 contains a valve 5 recalled by spring, the ex
rear end crosses the rear face 3 of the socket 8 to come into contact with the front end of the valve 13 of the existing socket 18. The valve 5 has a diameter corresponding to the medical fluid supplied by the network 25. The rear face 3 of the bush 8 further comprises a collar 6 bearing on a seal 16 of a ring screwed onto the existing socket 18.

The socket 8 also carries a radial screw 7 which, by being housed in a notch 9 of the existing socket 18, will immobilize the socket 8 relative to this socket 18.

When the assembly which has just been described is not used, the valves 5 and 13 are closed. When a plug or device is connected to the front face 1 of the socket 8, the valve 5 pushes
the valve 13 by releasing the gas. We obtain ai # nsi a double valve assembly, without disassembly, modification, or power cut of the existing outlet 18.

 A bracket 22 is held in position against the wall by a nut 21 screwed onto the periphery of the existing socket 8 and carries a housing 23. A cover 19 closing the front face of the housing 23 is maintained and fixed by a nut 20 screwed onto the socket 8.

In the event of an incident on the socket 8, it is always possible to dismantle it and temporarily connect the device to the existing socket 18.

The socket 8 can be produced with a system of connection to an existing socket other than the pins 4 cooperating with the notches 9, depending on the shape of the existing socket.

It is also possible to produce a socket 18 itself comprising a double valve.
