THIS DEVICE 10 ALLOWS THE APPLICATION OF AN INJECTION LIQUID OR A MEDICINAL PRODUCT TO A GINGIVAL FROZEN. IT INCLUDES A HANDLE 12 WHICH ENDS IN A FLEXIBLE TIP 14 DRILLED WITH AN OPENING 23. THIS TIP IS CONNECTED BY A DUCT 20 TO A TANK 32 CLOSED BY A CAP FORMING PISTON 34 SO THAT IT IS ENOUGH FOR THE USER, AFTER PLACING THE TIP IN THE GINGIVAL FENCE, PRESS THE CAP TO EJECT THE FLUID THROUGH THE TIP IN THE GINGIVAL FELL. DEPENDING ON A VARIANT, THE TANK CAN BE CONNECTED (IN 56 OR 58) TO THE HANDLE, WHICH IS THEN TUBULAR, OR BE ADVANTAGEALLY SHAPED IN THE TUBULAR HANDLE ITSELF.

Description

The present invention relates in a general manner to

  neral, to a combined therapeutic treatment device and stimulator of the gums and more particularly to a device for the effective application of a liquid

  S injection and / or drug at the gingival sulcus.

  Devices for applying an injection liquid

  and / or a gum drug for the treatment of pyorrhea and other gum-like diseases as described in the prior art, generally include a handle which terminates with a tip having

  appropriate configuration to facilitate access to Ll-

  In the device described in US Pat.

  No 1 586 302, the point is provided with a groove to accommodate

  see a syringe, the fluid discharged by this syringe

  driven by the groove to one or more openings

  formed in the end portion of the tip

  contact with the area of the gum that needs to be treated.

  Apparently, the device is manipulated to place the tip in the oral cavity in a determined manner

  and then the syringe is introduced as indicated.

  The risk of hurting the gums with such a device is obvious. It is necessary to position two separate devices in difficult conditions, particularly in

regards the syringe.

  The dental injection tubes described in the

  US-A-N'L 538,797 and 1,538,798 comprise a central portion of

  swollen trale, containing a fluid, prolonged by a

  strangled to form an elongated tip

  the ejection of the fluid by compressing by hand the

  Holding the Fluid As the amount of fluid decreases, it becomes necessary to apply increasing pressures to expel the fluid; the risk of hurting the gum is inevitable as an erratic movement of the

  Hand tied to physical exertion is likely to occur.

  In addition, increased air capture by the fluid

  may seriously affect the effectiveness of the latter.

  The dental tool, described in US-A-1,015,039, for supplying pressurized cooling water to an inlay impression (wax inlay) which is taken in the oral cavity, comprises a tubular handle which is

  l nge containing a compressible cartridge arranged internally

  and containing a cooling fluid.

  proximal trenches of the cartridge is in contact with

  fluid with a proximal tip with openings.

  A metal band that extends over the cartridge,

  is integral with an external compression member; a form

  this compression applied to the latter is transmitted to the metal band, crushing the cartridge and driving back the

  fluid through the perforated tip The cartridge is refilled

  che in the manner of a reservoir pen by compressing first and then releasing the compression member

  device is not designed to allow access to

  gingival nor to distribute a therapeutic agent.

  When the compression member is released from its compressed condition, air is necessarily drawn in. The method of applying pressure is inconvenient and inefficient.

  since a relatively large area is involved

  and that the local values of the pressure can vary

  mulberry. The present invention aims to reduce to a minimum or even completely eliminate the disadvantages

  above and the inconveniences with which they are

  by creating a device capable of applying a liquid

  of injection and / or a fluid drug, under pressure, 3 N to the gingival sulcus using relatively simple means

  which ensure the effective and uniform application of a

  if -n to the treatment fluid, the device being susceptible

  to be used many times.

  The object of this invention is therefore, in its aspects

  general, a device for the combined treatment, therapeutic

  gum stimulator, which includes an elongate handle that is terminated at its proximal end by a

  flexible tip with one or more openings

  jection of a pressurized fluid and shaped to facilitate the exploration contact of the tip with the sil-

  gingival, and conduit means connecting the

  i a fluid reservoir hermetically sealed by a

  plug inserted, removable, which is movable along the axis lnn-

  of the reservoir under the action of an applied force, to decrease the total volume of this reservoir and to increase,

  correspondingly, the pressure applied to the fluid

who is there.

  According to a preferred embodiment, the handle has a tubular construction and the internal volume delimited by the side walls of the handle, in combination with the

  removable insert plug, mount 4, so as to seal

  tically the distal end of the handle, constitutes the

fluid tank.

  The characteristics and advantages of the invention

  will emerge from the following description of modes of

  realization given by way of non-limiting example and

  FIG. 1 schematically represents embodiments of the invention in which the fluid reservoir is constituted by a physically separated element; FIG. Fig 1 Freeze 2a is a top view (shown in full) of the tip of Fig 2; Fig 3 is a longitudinal sectional view of another embodiment of the invention; Fig 3a is a top view of an insertion cap according to the invention; the Fia 4 and 4a represent in vertical section,

  partially broken off, a tip actuated by a

  This device, as schematically illustrated by the embodiment of FIG.

  elongated probe element, designated by the reference ge-

  10, having a handle 12 which may be of

  solid or tubular truction as explained later and which can be circular, rectilinear, etc. to facilitate

  hand grasping Probe 10 ends with an ex-

  proximal trough with a flexible tip 14 connected to the man-

  by a neck 16 oriented obliquely, as shown, to facilitate the positioning maneuver of the tip inside the oral cavity As shown in Figures 2 and 2a, the tip 14 has a cylindrical neck 18 to receive fixedly, within a channel 22, a conduit 20 penetrating to a depth compatible with the structural integrity of the device.

  by means of an adhesive or other suitable means

  requested, as is well known Cylindrical parts 24

  and 26 with stepped diameters ensure a compatible configuration.

  with the structural stability and avoid the formation of corners that could otherwise hurt the gum during use of the device The tip 14 is attached to the handle 12

  Through a ring 28 which is an integral part

  The tip converges downwards, as

  felt, in the form of a conical portion 26 that ends

  at the outer end 23 of the channel.

  The conduit 20 connects the tip 14 to the orifice of

  30 of a fluid reservoir 32, the latter, as a re-

  presented in Fig. 1, being a physically separated element

  of the probe and being, generally, constituted by a

  positive syringe type cylindrical cross section.

  A removable closing insert 34 comprises a

  cover 36 whose diameter is greater than that of the former

  tremite 4 e of reservoir 32 and thus provides a peripheral

  38 to facilitate the removal of the cap by hand

  34, as is necessary for example, when reloading

  The tank 32 The side wall 42 of the cap 34 comprises

  door, at its front or bottom edge 44, a washer 46 di-

  sized to functionally support its outer vertical edge against the inner surface of the wall

  lateral portion 48 of the fluid reservoir 32, thereby trapping

  the fluid content of the tank.

  The device of FIG. 1 is used as follows. The reservoir 32 is filled with a fluid, such as

  injection water or medication, and place the

  chon 34 as shown The diameters of the duct

  20 and channel 22, and in particular of the latter, are

  the fluid flow into the reservoir through the channel is prevented mainly by the surface tension effects of the fluid, unless and until the required pressure is applied, which causes the downward movement of the plug 34 along its longitudinal axis the probe is placed

  in the oral cavity so that the outer extremity

  re of the channel of the tip 14 is introduced into the gingival groove indicated at 50 in Fig 1, that is to say in the space between the gum 52 and the tooth 54 which is also

  called the tooth cell The location was thus de-

  finished, the user forcefully pushes the plug 34; the application of a relatively light pressure is sufficient to overcome the aforementioned flow resistance which results in the ejection of the fluid through the channel 22 in the determined region. In this way, a drug or an injection fluid is sent to a point below

of the gum line.

  In other embodiments, the conduit 20

  can be connected to the handle 12 at points 56 or

  respectively, 58, as shown in Dus interrom traits on

  In such cases, the handle 12 has a construction

  tubular tinn so as to stabilize a flow path

  continuous between the point of entry of the fluid and the channel 22.

  The connection 58 at the distal end is preferable

  since it is less likely to interfere with the DREHEN-

  sion or manipulation of the device by the user.

  The device can be used until the fluid has been substantially completely expelled. As it will be clear, the air in the reservoir 32 forms a sufficient mattress to allow the plug to

  function as a piston despite the complete absence of

  In all cases, the report

  the total volume of the tank and the total volume of the

  duit is usually very high and so wasteful

  resulting from the presence of unused fluid in the con-

duit is insignificant.

  The manipulation of the device of FIG.

  the user requires the use of both hands, on the contrary 2 C the device of Fig 3 can be manipulated with one hand In the latter device, designated by the reference

  60, the handle 62 has a tubular structure, its

  distal end portion serving as fluid reservoir 64 Ce

  reservoir is placed in fluid communication with an opening

  66 through a conduit 68 which passes through a neck 70 oriented obliquely, as described above, then the tip 72

  converging down which ends with aperture 66.

  The diameter of the reservoir 64 is relatively large in relation to

  port to that of the conduit 68 for the reasons described above, as well as to limit the length of the device

  to a practical dimension The handle 62 ends at an ex-

  distal end with a trumpet-shaped portion 74, or outwardly flared, which forms an end of the type

  funnel to facilitate the fluid filling of the reservoir.

  see 64 The recessed cap 76 has a similar configuration

  to that of the plug 34 of FIG.

  vircle 78 whose diameter is greater than that of the portion 74 in trumpet as shown in broken lines

  in Figs. 3 and 3a, which provides a preheating region

  The side wall 82 is provided with a sf-n lower or front end 84, a washer 86 to remove the plug 76 from the completely closed position (inserted).

  whose vertical edge is designed to come into operative contact with

  tional, when inserted, with the inner surface 88 of the handle 62 so as to thereby hermetically trap

  the fluid content of the tank 64 and to stabilize the posi-

stopper 76.

  The device of FIG. 3 is used as follows. The reservoir 64 is filled with a desired quantity of fluid of the type described. In the absence of pressure, no flow of fluid occurs through the opening 66 due to the effects of surface tension, as previously

  The plug 76 is inserted into the reservoir 64 until

  at a penetration depth sufficient to stabilize

  a certain amount of fluid, which is

  nevertheless very small, may flow through the opening

  FIG. 66, which indicates the attainment of a fluid ejection pressure. The device is placed in the oral cavity in the manner previously described, using the thumb or index finger of the hand holding the driving device.

  the plug 76 so as to trigger and maintain the

  jection of fluid through the opening 66.

  In another embodiment, the reservoir can

  be filled with a sachet, cartridge or other

  appropriate frangible, enclosing under pressure the liquid

  Injection or medication is introduced into the reservoir.

  see the bag, which has a configuration in accordance with

  inside the tank 64 and fits without play, from

  way that it comes in support against the abutment means pre-

  seen in this tank, such as an annular flange 90

  (Fiq 3) which is an integral part of the handle 62 and which delimits

  Means a flow passage 92 having a diameter at least equal to that of the conduit 68. In this embodiment, the plug 76 has a shape such that, when it is completely inserted, it exerts on the bag,

  either through direct contact must through a mate-

  tired of air, enough pressure to break it.

  Thus, the proximal end portion of the bag that abuts against the flange 90 can be adapted to break under the pressure conditions that exist when the plug is substantially completely introduced, which releases the liquid content that automatically comes under pressure To replace the stop means, the diameter

  tank 64 can be strangled at its end.

  resultant causing rupture of the bag.

  In pouch embodiments, it is re-ordered to use flexible tips of the type shown in Figs 4 and 5. In Fig 4, a flexible tip 94 is provided with a valve type valve 96 which is normally

  closed to prevent the flow of fluid between

  98 and 98a of the duct, the portion 98a ending with the outlet opening 100 The valve 96 is provided with a central horizontal slot to delimit upper portions

  and lower equal, indicated at 102 and 104 in Fig 4a.

  In its closed position the valve 96 provides a hermetic closure, resistant to pressure, and stable, against

  the pressure exerted by the contents of the reservoir 64 Ce-

  during, when the tip 94 is rotated as shown by the direction indicator arrow-of Fig 4a, which is the case when the surface 106 of the tip 94

  is pressed against a tooth, the flexion of the tip 94 pro-

  the opening of the valve 96 to the indicated position

  by the valve portions 102 and 104 in Fig. 4a.

  In Fig 5, an inner surface 108 of a

  tip 110 is provided with slots 112 normally closed, sen-

  the surface 18 In the positi-

  troduced and depressed to the maximum depth permitted by the

  resulting back pressure This indicates the maximum depth

  male compatible with stable positioning of the cap.

  In operation, it is sufficient for the operator to flex the pointer

  in the manner described to trigger and maintain the

  jection of the fluid, and it is not necessary to press the

plug.

  The tips of the invention may be of hard rubber or similar polymeric material having equivalent elasticity and mechanical strength. The selected material must, in any case, be inert with respect to the contained fluid. The outer surface of the tip must not to be irritating to the gums and it must be tasteless
