ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pad. More particularly, the present invention relates to a single pad for providing both an anesthetic and an antiseptic for an injection site.
2. Description of the Prior Art
Cleansing solutions, such as alcohol, are normally applied to a patient's skin area where certain medical procedures are to be performed, such as insertion of a hypodermic needle for various purposes including administration of medications, blood withdrawal, and initiation of intravenous therapy.
In the past when an injection was to be given, it was common to swab the affected area both before and after the injection. This is usually done by another than the one making injections, or by the injector laying the hypodermic syringe aside while the antiseptic is being applied with swab held in an entirely separate instrument. The need to lay aside the hypodermic syringe and use a separate instrument, such as forceps or the like to apply the antiseptic to the point of injection caused considerably lost time.
When using the hypodermic syringes presently on the market, the physician still has to carry with him when visiting his patients, a bottle of antiseptic liquid, such as either, alcohol or the like as well as a box of absorbent material, such as cotton. Furthermore, every time an injection has to be made, he has to go through several motions in order to sterilize the skin through which the injection is to be made.
All these operations are time consuming and this is rather important, particularly for the physician whose schedule is usually very heavy. Also, it happens from time to time that the physician runs out of either the antiseptic liquid or the absorbent cotton or both, and on such occasions none may be available on site.
Furthermore, the skin area is often not anesthetized to reduce pain from the procedure, since known means for applying anesthetic agents are cumbersome and time consuming.
Numerous innovations for medicinal applicators have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.
FOR EXAMPLE, U.S. Pat. No. 4,243,035 to Barrett teaches a hypodermic syringe and integral antiseptic dispenser, with the syringe having a barrel portion adapted to contain fluid to be injected. A needle is operatively mounted on one end of the barrel portion, and a plunger is located on the other end of the barrel portion, with appropriate manipulation of the plunger bringing about the injection of fluid from the needle. The improvement comprises a presoaked antiseptic dispenser that may be disposed on the barrel portion, with the antiseptic dispenser making it convenient to clean the intended injection site immediately before the injection. The antiseptic dispenser may take the form of a pad carried by the barrel portion of the syringe, or a generally cylindrical pad-carrying member encircling a portion of the needle end of the syringe, or any of a number of related configurations.
ANOTHER EXAMPLE, U.S. Pat. No. 5,690,958 to McGrath teaches a unit dose chlorhexadine gluconate (CHG) applicator wherein a unit dose of the CHG is contained in a hermetically sealed manually crushable glass ampule that has an internal volume not significantly greater than the unit dose volume of the CHG. The CHG in the ampule has an effective shelf life of at least 24 months. The glass ampule of the applicator is preferably protected by a flexible cover to protect the user's hand during manual crushing of the ampule to release the CHG therefrom. In one embodiment of the invention, a cylindrical glass ampule is housed within a tubular, flexible synthetic resin cover which has a porous applicator swab at one end thereof. Upon crushing of the glass ampule, the CHG released therefrom impregnates the swab allowing the user to spread the CHG across an area to be sanitized. In a second embodiment of the invention, a cylindrical glass ampule is received within a semi-cylindrical, open-sided body cover having a flange portion that mounts a sponge-like swab communicating with the interior of the body cover. Opposed integral wing-like gripping members on the ampule permit the user to crush the ampule by squeezing the members toward one another whereupon the CHG is released from the ampule and impregnates the sponge swab. The swab soaked with the CHG antiseptic may be rubbed across an area to be sanitized.
STILL ANOTHER EXAMPLE, U.S. Pat. No. 5,704,906 to Fox teaches a topical anesthetic-cleansing solution and applicator. The anesthetic-cleansing solution comprises an anesthetic agent such as Benzocaine and a cleansing solution such as alcohol. The applicator includes a swab and outer packaging housing the swab in a generally sterile environment. The swab includes an elongated member and an absorbent tip attached to the elongated member. The absorbent tip is impregnated with the anesthetic-cleansing solution. A method is also provided for using the applicator. The method includes the steps of holding a portion of the packaging covering the swab elongated member; removing a portion of the packaging covering the absorbent tip to expose the absorbent tip; and applying the absorbent tip on the patient's skin area to be anesthetized and cleansed.
It is apparent that numerous innovations for medicinal applicators have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described.
SUMMARY OF THE INVENTION
ACCORDINGLY, AN OBJECT of the present invention is to provide a single pad for providing both an anesthetic and an antiseptic for an injection site that avoids the disadvantages of the prior art.
ANOTHER OBJECT of the present invention is to provide a single pad for providing both an anesthetic and an antiseptic for an injection site that is simple and inexpensive to manufacture.
STILL ANOTHER OBJECT of the present invention is to provide a single pad for providing both an anesthetic and an antiseptic for an injection site that is simple to use.
BRIEFLY STATED, YET ANOTHER OBJECT of the present invention is to provide a single pad for providing both an anesthetic and an antiseptic for an injection site. The pad includes a first layer of material, a second layer of material, a third layer of material, an antiseptic solution, and an anesthetic solution. The second layer of material overlays the first layer of material. The third layer of material overlays the second layer of material. The antiseptic solution impregnates the first layer of material and cleans the injection site. The anesthetic solution impregnates the third layer of material, anesthetizes the injection site, and is used by merely turning the pad over after the antiseptic solution has been applied.
The novel features which are considered characteristic of the present invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawing.
