Upon reading the teachings of this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as cost, future technologies, future bio-matter shielding needs, etc., other uses of bio-matter shields, such as, for example, shielding back-spray of syringes, shielding otoscopes during examinations, etc., may suffice. By way of example, it is noted that such a transparent shield as described could be used in combination with other medical devices such as a syringe to provide similar cough protection as during a tonsillar aspiration. The same device can also be attached on a syringe to provide other functions such as irrigation spray protection as a wound is infiltrated under pressure, with the flexible plastic shield forming alternatively a concave or convex shield depending on the positioning to which the shield is bent.

The same device of the cough shield, as above noted, could also be used to attach to another component such as a syringe for the purpose of acting as an infiltration splash shield. One usually infiltrates a wound with a needle and syringe correctly by removing the needle while simultaneously using a high pressure counteracting force to infuse the medication, such as a local anesthetic into a wound. And it is the common safer practice to inject medication after a needle is inserted into the skin; then the syringe plunger is pulled back to create a negative pressure to make sure that one does not withdraw blood; this would indicate that one is undesirably in a blood vessel rather than in the desired location of being in the upper-layers skin tissue itself where the nerve endings are located. After such determination is made that one is not in the blood vessel, one then forces the medication through the needle into the skin while withdrawing the needle. This requires the use of a high pressure to infiltrate the closed space of the skin with the infused medication, requiring greater attention to the force being instilled and the forward pressure of the syringe and the counteracting withdrawing forces of pulling out the needle. In addition, as a great force is often required, the hand-held system is often less stable. As the needle is being removed, the position of the open tip portion of the needle position cannot be reliably visualized as it is under the skin. Often, as the needle is fully withdrawn from the skin, the continuing high pressured medication continues and sprays the medication into a patient's bloody wound, displacing not only the medication in an uncontrolled spray-like fashion, but also the patient's bodily fluid. This creates a health hazard to medical personnel as well as increasing cleanup time and soiling hospital equipment and patient clothing. Some medical personnel put on costly, cumbersome and time-consuming face masks with shields and gowns for protection during such a procedure. Others place their hand over the site which obstructs the sight and places their hand in close proximity to the potentially hazardous free end of the injecting needle. Having a simple inexpensive shield that could work in combination with such a syringe and needle system would be desirable. Having a device system that could also attach to other devices for other protective functions such as attaching to a tongue depressor 1:0 act as a cough shield would provide more versatility and increase the potential marketability and success of the device. Having a device with a means of attachment to another device would eliminate the number of hands and operators necessary to achieve the desired function or procedure. Having such a device with an easy simple attachment would speed the completion of the procedure as would desirable in a busy doctor's office. Having such a device that is easy to use and inexpensive to manufacture and therefore to sell would increase the use of the device and therefore reduce the potential contamination of hospital personnel from patients. Having a transparent material would allow visualization through the shield. Having a flexible material might allow for a nonplanar attachment of an otherwise flat material. Having an attachment of flexible material on a convex surface would increase the rigidity of the material and would stabilize other portions of the material bent in a concave fashion. Having a stable material bent in a concave fashion would permit relative narrow attachment surface to accommodate a relatively larger concave bent surface to act as a splash shield. By varying the position of the bend, one could vary the angle and position of the shield. Such a large bent splash shield would protect the operator behind the shield and would not interfere with the forward advancement of the needle. Since the shield must extend beyond the syringe and preferably cover a large area, having a bent shield would facilitate such an operation without the shield edge obstructing the advancement of the needle tip below. Such a shield could be made of an inexpensive flat flexible material with at least one attachment means and could be used for other functions as well, such as a cough shield on a tongue depressor. Such a preferred shield would be relatively simple, inexpensive to manufacture, increasing the marketability and usage of the device for its desired advantages. The same principles described above could be related to other components and procedures such as wound irrigation without a needle.
