This invention refers, in general, to shield for vaccination pustules, and more particularly to certain useful improvements insuch shields as used for pustules from vaccination against smallpox. v

Heretoforeconventional uses include transparent and colourless shields, provided with a sticky or adherent device to be attached to the skin over pustules from vaccination against smallpox. Such shields merely prevent rubbing of the clothes against the pustules from vaccination, which is troublesome, particularly when the vaccine lymph begins to act. My invention provides, as a new product, an improved shield which is principally characterized by the fact that the window or transparent dome of the shield is of red colour, thus preventing any outside natural light from reaching the vaccination pustules.

I have proven by careful research and many experiments that'by using shields of a red colour which color prevents the admission of outside natural light, their use over the Jenner pustules from vaccination against smallpox prevents suppuration and has a perfect immunizing power, provided the shields are applied in due time. The vaccination pustules, under the action of this new protective red-coloured window, do not go through the same period as cerous pustules that rupture, but, on the contrary, soon get well, without leaving any vaccinal scars. Vaccination pustules which are protected in this manner do not affect childrens general condition or appetite, it being possible to washthem as usual and to take them out daily to enjoy fresh air, without the requirement of any dietetical precaution, in view of the fact they are not subject to suffer any diarrheal or other incidental and usual troubles.

In the use of my red shield it is possible to vaccinate children without danger of any complication, irrespective of their age, general .condition (rickets, a delicate health,'skin irritations, etc.) and regardless of the season of the year, as the warm weather has no ill eflects at all. In short, by using the red protective window, the following well-known and usual troubles and dangers are avoided, without the vaccination losing any of its perfect immunizing powers whatsoever against smallpox: V

l. Subjective signs, such as an intense itching and pains brought about by the inflammation in the inoculated zone, besides painful in- I flammation of regional glands.

2. The vaccinal fever that occurs about the eighth day, which in general fluctuates from 38 to 40? C., and which normally lasts three days. 3. Troubles inthe general condition, which appear as} agitation, lack of. appetite, sleeplessnes's, irritability, depression, nausea, diarrhea, etc. Y I 4. The contingent and dangerous anomalies accompanying the evolution of the vaccination pustules, such as the polymorphous vaccinal exantherna, secondary eruption, generalization of the vaccination pustules, etc.

5. The auto-inoculation of other regions of the organism by the vaccinated person, who infects his or her fingers, and who frequently inoculates his or her genital organs, eyes, etc.

6. The transmission of vaccination pustules to other persons through contaminated fingers.

7. The vaccinal eczema, which is the most terrible complication.

8. Complications during the evolutionary process of vaccination pustules, through the infection of pustules b-y'the nails, the result being ulcers, gangrene, erysipelas, etc.

a death rate of 50%, the rest being frequently paralysis and other serious complications.

As above stated, my invention provides substantially and essentially a transparent shield, which is generally similar to those already known, but distinguishes therefrom in that it is made of red colour to prevent the passage of outside natural light to the vaccination pustules, thus securing the above-mentioned advantages and effects.

The features of the invention will be apparent from the following description in connection with the accompanying drawing, the same reference numerals being used to represent the same parts in the figures shown.

In the drawing:

Fig. 1 is a front view of the improved shield.

Fig. 2 is a plan view of the same.

Fig. 3 is a sectional view on the line A-B of Figure 2.

Fig. 4 is a vertical section of a modified construction to provide ventilation eifect.

In the drawing, the shield proper It is shown as a convex sheet and of a material having transparent properties, it being, as previously emphasized, of a red colour which results in the efiects already mentioned. The convex sheet I0 is secured at its base by means of flange H or the like, to a disk or washer l2 made of adhesive tape to facilitate its application to and rest on the skin, precisely over the vaccination pustules to be protected by the red transparent convex portion l0; care being taken that the shield be centrally located over the pustules, as is conventional practice in shield application.

It is indispensable that the shield Ill be red and transparent, to preclude the entrance of natural light, and desirable ventilation'may be provided for through a double bottom l3, secured to the inside of the convex sheet 10 by suitable means, said double bottom precisely underlying perforations l4 formed in the sheet I!) for the admission of air. The rays of light passing through the said perforationsv I4 is controlled as to color in passing through the double bottom I3, as the latter is made precisely of the same red and transparent material as the con vex sheet I0. I

Fig. 4 shows a slightly modified arrangement to provide desired ventilation. In this modification the double bottom I3 is in the form of a disk secured along its periphery to the interior portion of the convex sheet 10, the perforations H in the sheet l0 being'restricted to one diametric side, whileperforations 15 formed in the necessary ventilation without the admission of outside natural light.

Having thus described the invention, what I consider as new anddesire to secure by Letters Patents is:

1. A shield for smallpox-vaccination pustules constructed of red transparent material.

2. A shield for smallpox-vaccination pustules of two layers of red transparent material.

3. A smallpox-vaccination shield comprising a convex transparent formation of a red color.

'of convex form and of a red color, and a transparent disc of red color arranged within and spaced from the shield proper.

6. A transparent smallpox-vaccination shield of convex form and of a red color, and a transparent disc of red color arranged within and spaced from thershield proper, the shield proper and disc. being perforated for ventilation, with the. perforations arranged to prevent light rays passin directly through said perforations JORGE ERDELY.
