The object of the invention is a multi-penetrating vaccinating device with adaptable effects according to the vaccinated subjects. The subject of the invention relates to the technical field of devices for introducing agents into the body. proposed means or means of vaccinating with multiple tips or teeth that soak or otherwise immerse the vaccine to be inoculated to the subject to be vaccinated "
However, it is known that therapeutic inoculation is related to the age of the vaccinated subject. The older the subject, the greater the amount of inoculated vaccine must be important. Sometimes, on different parts of the skin, the tips or teeth of the vaccinating organ through the patient's skin. The effect is unpleasant for the vaccinated subject who may have relatively wide scars. convenient for the operator and leads to a loss of time "
According to the invention, it has been sought to overcome these drawbacks and to create a multi-penetrating vaccinating device with adaptable effects according to the vaccinated subjects, acting under a single pressure through the skin. This device is remarkable in that it includes a frame. having a portion cited a gripping portion and thrust, while are formed on the other side of this mount one or stepped spans or equiva-lent provisions for the fitting or removable assembly of a- end concentric sleeves or hollow supports engaged into each other, the free ex-tremité said sleeves or supports and the central bearing having a plurality of points, teeth or other asperities penetration "

In order to make the object of the invention more concrete, it is now described in non-limiting embodiments illustrated in the figures of the drawings.
The device according to FIGS. 1 to 8 consists of a frame made of a gripping part 1a forming a pallet, connected to a circular plate lb, for example.This plate, opposite the pallet, has cylindrical staggered bearing surfaces for example, 1o, 1d, the, If, ...
The first seat (1b) is intended to receive under pressure and in a sealed manner the open end of a protective cap forming a lower reservoir for the vaccine to be inoculated. Note nr.-i the cap is conical to facilitate gripping. It is also possible, at the limit, not to provide a cap or only a protective sheath, the vaccine being taken in an independent container.
The last reach (if) has on its end face tips, teeth or sharp edges 1q, in a determined number, for example five (Figure 4) "
Intermediate bearing surfaces 1d, 1c, n0 are in any number (1,2,3 ") and are intended to receive by force-fitting elements 4 or hollow supports such as sleeves 3, 4> . which when enga-gés in abutment against the upper shoulders, are in the same alignment at their free end which also has points, teeth or roughnesses 3a, 4a, ··· in a determined number, for example nine on the sleeve 3 and · eighteen on the sleeve _4 (Figure 4) o
These sleeves have a cylindrical bore and are conical to their periphery with the large diameter on the tips side. This arrangement makes it possible, in combination with the dimensioning of the staggered spans, to provide the lower part with a small space E between the sleeves and between the sleeve 3 and the bearing surface 1f, which space is used to retain a certain quantity. On the other hand, the conicity or counter-slope of the sleeves facilitates manipulation to engage or disengage them from their reach, because of the weakest wall at this location.
As can be seen in FIGS. 5 to 8, the number of penetration spikes can be varied rapidly and conveniently as a function of the subject being vaccinated, by removing a sleeve (FIGS. 5 and 6) two sleeves (FIGS. 7 and 8) or more If it's happened.
Thus *, the complete device, that is to say with all these tips, allows the maximum requested vaccination, with a single pressure on the skin. If we want to inoculate less vaccine, we remove one or more 'sleeves'. For a minimum vaccination, the terminal reach 1f is sufficient »
Sleeves and circular bearings have been provided for reasons of simplicity, manufacturing and concentration of the tips, in order to obtain maximum inoculation on a minimum skin surface. But it is easy to pre-see other forms bringing as much concentration. than. sleeves and sleeves of polygonal shape in section (square ^ hexagonal .. "o) o
According to an alternative embodiment illustrated in FIGS. 9 and 10, the liner J only has a bearing surface 5a intended to receive the cap 6. On the end face of the bearing surface are formed: a bore or axial recess 5b which is engaged by force a solid support 7. equipped with teeth 7e and concen-trically to this bore, circular grooves I - 5ά .oo "" receiving the sleeves 8j J>? »<, ♦«, equipped with teeth 8a, 9a »» »».
It is also possible to form a central bearing directly in the mass instead and in place of the support 6. It should also be noted that the teeth or tips may all be of the same length or of different lengths, as shown in FIG. 11 where it can be seen that the The shortest teeth are at the center and the longest at the periphery, the teeth 12 and others being intermediate. To obtain the same effect, it is possible to provide tips of the same length but of different lengths (in the case of FIG. 9) or not at the same level (in the case of FIG. 3, especially). .
This different penetration of the tips makes it possible to adapt the depth of inoculation to the subject in the presence.
For example, and not limitation, provides the following dimensions: - length of the closed device: 39 millimeters, -Outer diameter or circumscribed diameter: about 12 millimeters, - length of the pallet ± 17 millimeters, - length of the tips About 3 millimeters, or 3, 2, 8 and 2.5 millimeters, they are of different lengths. - taper of the sleeves about 2 degrees, - space between the sleeves about 0.5 millimeters?
According to these provisions, the rapid adaptation to the vaccinated subject of the quantity of vaccine to be inoculated by the mobility of the spike-carrying elements is emphasized, thus ensuring a precise vaccination according to the subject, in particular according to his age; this in one pressure on the skin. - The concentration of inoculation tips by the arrangement of the tips, allowing maximum inoculation on a minimum skin area, which avoids oibatrices too important, - the intervals between the sleeves ensuring the retention of the vaccine.
According to FIGS. 12 and 13 there is illustrated alternatively a booster device whose mounting has removable adaptation arrangements for sleeves or hollow supports, of the cylindrical bearing-staggered type of the mount, but it is obvious that these sleeves or removable supports can be mounted in using equivalent arrangements such as the centric grooves described above.
The mount 13 has as in the first embodiment, a pallet gripping portion 13a, connected to a circular tray 13b or other sectionA opposite the pallet, the plate is extended by cylindrical stepped bearings 13o, 13d, 13e, 13f, 13%, .... The first range 13c receives in pressure the open end of a cap $ 4 <The bottom receives the vaccine to be inoculated
The last span (13q) has on its end face penetration asperities (teeth or spikes 15 for example) in a suitably-determined number, 6
Intermediate bearing surfaces 13d, 13c, " serve in any number, and are forcibly fitted with sleeves or hollow supports 16, 17, bearing at their end opposite to the insertion of penetration asperities. (Teeth or spikes 18-19 for example) in number - suitably determined "" ".
The sleeves 16, 17 preferably have near their endportant the tips, parts, bulges or shoulders 16a, 17a: having tapered contact faces for example. The same conical arrangement is found in the form of shoulder or chamfer 13h between the bearing surfaces 13 f- and 13 q, and 10 inside the cap 14 (surface or chamfer 14a) .It is not excluded in the frame Of the invention, the bulged portions or shoulders have contact faces perpendicular to the general axis of the device.
These contact surfaces provide an effective seal for mounting, to prevent the vaccine from rising, during handling, along. 15 sleeves. Indeed, the sleeve 16, fitted on the bearing 13e, is in support on the surface 13h the sleeve 17, fitted on the bearing surface 13 d taking .support on the surface of the shoulder 16a of the sleeve 16, and the cap, emman 13c is resting on the surface of the shoulder 17a of the sleeve 17 °. It should be further noted that to facilitate the insertion and disengagement of the sleeves, on the periphery of said sleeves, asperities are provided. such as grooves 16b - 17b, grooves, grooves, grid, ... In a manner improved with respect to the previous embodiment, the conicitê more important of the sleeves or supports increases the rigidity and facilitates the. grasping and manipulations. '
The asperities of penetration into the skin are preferably desdents or tapered tips. FIGS. 14 to 24 show different shapes of tips or teeth which may be of equal or unequal lengths.
For example, FIGS. 14, 15 and 22 show tips 20 whose section is three or four branches with a convex or concave flat surface. not- "
In Figures 16 and 17, the tips 21 are cruciform section thin branches; In Figures 38 and 19, the spikes 22 are of thick-section form with thick branches, and in Figures 20 and 21 the spikes 23 are spindle-shaped with thick branches and curved faces (concave or convex). spikes 2p -> ort with polygonal section with concave surfaces.
In these various forms, the surfaces between the edges of the branches constitute reserves of vaccine. 7 '0 5 448
Finally, in FIGS. 23 and 24, there is illustrated the conformation of a cylindrical tip 24 having a chamfered end 24a and presenting one or more cavities or concave bow-shaped shapes 24b.
According to this embodiment, the following is particularly emphasized: the sealing of the device at the level of the shoulders. and contact surfaces 13h - 16a - 17a - 14a preventing the vaccine from flowing and unnecessarily depositing along the sleeves. the shoulders or the bulges of the sleeves increase the rigidity, noticeably diametrically transverse. The placement of each sleeve or support helps to perfect the mounting of the sleeve or support previously engaged, and, consequently, the tightness of the assembly. The arrangement of the shoulders, as provided, has the effect of thus moving the pre-tensioning part away from the tips when handling the sleeves, which avoids having the fingers in contact with the vaccine and the tips. . - The teeth or tips of different lengths (the least long in the center of preference) ensure easier progressive penetration under a reduced pressure, eliminating or reducing as much painful perception of the patient. . - Section profiles with several radial branches, cruciform, bevelled, 20 faceted, or cavities or cuvettes allow better retention of the vac-cin in the corners, or internal shapes or cavities on the straight or curved faces, this in particular by the surface tension effect. These points of roughness, for a surface or section of equivalent penetration have a larger sur- face carrier, which allows to reduce the number of points without 2 resort to the effect of capillarity extreme approximation points. - better penetration of the vaccine by the effect of the radial branches of the tips that open the skin in a corresponding way without the lips of the skin do not return or wipe the vaccine, especially the vaccine deposited in the angles or internal advantages entered the branches FIGS. 25, 20, 28, 2, 36 and 36 show a vaccinator device according to a first embodiment of the invention. second variant in. wherein the device comprises a mount 26 consisting of a central two-stage central cylinder 26a whose free end carries at least one and generally several penetration points 26b. In the upper part the frame has a cylindrical shoulder 26c extending partially and for example by fins 26d diametrically opposite.
Axially, the mount has a tapered bore 26e tapered at the narrower bottom portion by a throat 26f opening at the free end.
On the first stage of the bearing surface 26a is engaged with friction the bore 2 "a of a sleeve 27, having an upper flange 27b bearing on the shoulder 26c of the frame and points 27c at the free end annulai-re Other sleeves may be friction fit on the outer diameter of the first sleeve 27. In the illustrated example, there is only one sleeve, the outer diameter 27d of the sleeve 27 receives friction a cap 2o for protecting the tips on a mechanical level (to avoid 1'emous-wise shock or friction) and medical uv vlan (to ensure sterilization s being understood that this sterilization is also performed in the upperparts opened in 26th by conditioning the device in a package Z (FIG. 23). It should be noted that the tips 26b and 27c are of different lengths, so that the tips 26b closest to the axis of the frame are the longest. and the s the shortest points on the largest diameter, constituting together a fictitious surface (Figure 25) convex with respect to the axis and the direction of penetration of the tips. In FIG. 27, there is illustrated a member intended to contain the vaccine to be inoculated, according to a first embodiment constituted by a flexible flexible cap-sule 2g comprising a reservoir portion 29a followed by an end-cone 29b fitting into the 26th bore of the frame and a 29c-breakable pellet. The tip 29b and the bore 26e have a suitable conicity and for example conform to the French standard S 9OOII.
According to another embodiment illustrated in FIGS. 31 and 32, the vaccinator device always has the sleeve or sleeves 27 and the capu-chon 28, while the frame 30 has the central bearing 30a with the tips 30b> the cylindrical shoulder 30c, the fins 30d and the bore 30e with lower throttle 30f «
The upper part of the shoulder 30s has a 30g boss vertically extending by at least two uprights or 30h ribs, connected to the upper part to a crown or bearing 30i · The nervuressess are located outside a diameter delimited by a bore 30j of the bearing 30i and by a chamber 3CSc of the boss 30g opening in the conical bore 30e »
This particular form of the frame allows the engagement and guidance of a vaccine container (FIG. 33) in the form of a flexible tube 31 comprising a reservoir portion 31a followed by a corresponding conical tip 31b. 9 to 10 20 25
U at the 30th bore of the mount, and a breakable pellet 31c * In Figure 34 on & illustrated another form of vaccine container type syringe 32 comprising a body or tank 32a terminated by a ferrule 32b corresponding to the conical bore of the frame and a piston 32c.
This provision allows a controlled distribution and dosed at the will of the vaccine, case by case, by the practitioner. Note that the flexible tube 31 and the syringe 32 can also be used with the vaccinator device according to the first embodiment.
Specific arrangements have also been made to facilitate handling, in particular the fins 26d or 30d of the frame allowing the easy removal of the removable sleeve or sleeves 27 whose upper support flanges 27b project beyond the cylindrical bearing surfaces 26c or 30c of the cylinder. ture (Figures 26 and 32). It is also possible to provide on the sleeves further blades 27θ> 27f,. <> ·., (FIG. 30) offset angularly with respect to the wings 26d of the frame
According to another variant, it is possible to provide different colors for the frame and the sleeve or sleeves, in order to facilitate handling.
This color differentiation can be performed on all elements or only on the fins or flanges.
The implementation of the vaccinator device is now described by referring to FIGS. 31 and 36 of the drawings. FIG. 35 shows a complete vaccinating device, that is to say comprising a maximum of penetration points, in which a vaccine capsule is engaged by friction. The practitioner holds the capsule between the thumb and the index finger and press the vaccinator on the patient's skin while pressing on the faces of the capsule (arrows f1, f2); the end of the presser fingers being in contact with the fins of the frame, the vaccine is then, by the strangulation 26f, in the space between the tips and some quantity enters the epidermis.
According to another practice, the practitioner tie ^ t the capsule engaged in the firing in the bore 26e, between the index finger and the middle finger pressing the capsule and rest on the fins of the mount (Figure 36 where it is represented only mount in action), while the thumb passes behind the forearm to form clamping jaw in response to the pressure force.
With the flexible tube 31 the action is similar in that the practitioner holds the frictionally engaged tube in the mount (broken lines, Fig. 31) and presses the device against the skin while pressing the tube. If the practitioner uses the graduated syringe 32, he will hold the syringe-vaccinator together with one hand while pressing it on the skin and will actuate the piston 32c of the other to deliver a quantity. dose of vaccine.
The benefits are apparent Link of the description, in particular it is emphasized: 5 - the easy handling of the vaccine-vaccine container assembly, as well as removable elements of the vaccinator by fins, glue-holders or different colors, - the precise dosing of the vaccine, avoiding a significant waste of the vaccine when introduced into the vaccinator simultaneously with penetration, In some places, spikes, sleeves and frames may be divided into: - the sterile packaging of the vaccinator device and possibly the vaccine container, - the penetration first of the central tips then of the extreme tips, of different lengths, or the different length of the frame and sleeves, ensuring a better vaccination effect since the vaccine is introduced in the central part "15
