BACKGROUND OF THE INVENTION The field of this invention relates to a board to facilitate the positioning and maintaining of medical patients hand and arm in a particular position to facilitate the insertion and maintaining of a needle into the veins in the back of the patients hand. Also, the board may optionally be used to facilitate the insertion and maintaining of a needle into the arterial artery through the underside of the patients wrist.
Intravenous injections is a most comrmn procedure of seriously injured or ill patients within hospitals. It has been found to be preferable to feed intravenously through the veins located in the back of the patients hand which can be referred to as the dorsal metacarpal surface. To facilitate the insertion of the needle into the vein, it is desirable that the hand be located in a particular position so that the needle can be inserted straight into the vein. After the needle is inserted, it is preferred that the needle be located in a substantially parallel relationship to the vein. This parallel relationship is essential in order that the fluid injected into the vein will be injected properly. The point of the needle is cut sharply at an angle in order to facilitate insertion into the vein. The sharp point of the needle is capable of puncturing the other side of the vein wall if the needle should be inserted improperly or should it be moved after it has been inserted.
Intravenous feedings occurs over a substantial period of time and it is not uncommon for a single patient to be intravenously fed for several days. Immediately after most surgical operations the patient is fed intravenously. Frequently the patient will become restless and will make quick movements with his hands and arms after an operation. Such quick movements can frequently cause the intravenous feeding needle to be broken or to cause injury to the vein or to be removed. Also. when the needle is maintained in the patients arm for several hours or several days, the normal movements of the patient may cause the same problems to occur. Therefore, it has been found to be desirable to fix the patients arm to a board so that the patients wrist cannot be bent. It is in the bending of the wrist that normally the problems occur with respect to the needle.
Previously, there have been available some intravenous feeding boards to overcome the above noted problems of the intravenous feeding needle. A few of such boards have been designed quite complex in construction and therefore are quite costly. Others of such boards are not designed for the patients comfort and make no attempt at ventilating the board. It has been found that after a period of time that perspiration will collect between the board and the patients arm and hand. This collection of perspiration can become quite uncomfortable to the patient and also encourages unsanitary conditions.
The majority of the intraveous feeding boards in the prior art have not been designed to be disposable and therefore require periodic cleaning and sterilization. It
would be desirable to design an intravenous feeding board which could readily be disposed ofv During surgical operations, an electrostatic charge can be quite hazardous. In anesthesiology, extremely explosive gases are used which are capable of igniting such gases causing injury or death to the patient. It is required that any item used in the operating room be capable of dissipating electrostatic charges. In the prior art, no known intravenous feeding board included means to make the board electrically conductive.
SUMMARY OF THE INVENTION The intravenous feeding board of this invention is essentially a flat board with a portion of the upper surface of the board being mounded to bring the dorsal metacarpal surface to the preferred angle to facilitate insertion of a hypodermic needle. The board of this invention includes a substantial number of ventilating apertures which connect with an enlarged ventilation cavity located within the underside of the board. The internal cavity is ventilated to the ambient so that accumulated humidity can escape. Included within the board is an enlarged ventilating hole positioned adjacent the palm of the hand of the user. It is in the area of the palm that the greatest amount of perspiration occurs. A strip of electrically conductive tape is placed across the board to electrically ground the board to the surface upon which it is placed.
The primary objective of the intravenous feeding board of this invention is to construct the board in a simple manner of a styrofoam plastic material so that the board is quite inexpensive to manufacture and is readily disposable. A further objective of the board of this invention is to construct the board so that it is comfortable to the wearer during even prolonged periods of use. To aid in obtaining this comfort feature, the board is to include ventilation means to eliminate accumulated perspiration.

DETAILED DESCRIPTION OF THE SHOWN EMBODIMENT Referring particularly to FIG. I of the drawings, there is shown the intravenous feeding board 10 of this invention. In phantom there is shown a human hand 12 positioned as it would be upon the board 10. The board 10 includes a top 14, a bottom I6, a front end 18 and a back end. The entire board It) is constructed of styrofoam plastic material and is to be molded in a single operation. Although styrofoam plastic is found to be preferable, it is to be understood that other types of material could be selected.
Formed upon the upper surface of the board 14 adjacent the front end 18 is a mound or raised rounded portion 22. At the front portion of the mound 22 are a plurality of grooves 24 to allow the fingers of the user to lie comfortably upon the board 10. The purpose of the mound 22 is to position the back of the hand so that the veins within the back of the human hand are pushed upwardly and straightened to some extent in order to facilitate the insertion of a needle 32. Such hollow sharp pointed needles are used to feed patients intravenously, to insert catheters within the blood stream, or to inject drugs or antibiotics.
Positioned on each side of the mound 22 are ledges 26 and 28. If the board is applied to the patients right hand, the thumb of the patient will rest on ledge 26 with the little finger resting on ledge 28. If the board is used on the left hand, the opposite would be true. The lateral edges of the board 10 adjacent ledges 26 and 28 are rounded so that if in chance the board he comes lodged beneath the patient's body, there will not be any sharp edge which would cut off blood circulation. This is particularly desirable since frequently pa tients that use such boards are either unconscious or heavily drugged.
Formed within the bottom 16 of the board 10 is an internal cavity 30. In the event that a patient proceeds to use the board as a leaning support such as when trying to sit up in bed, the board will be strong enough to support the patients weight.
Formed through the board 10 and connecting with the cavity 30 are a plurality of ventilation apertures 34. There is a ventilation aperture 34 which connects with each of the finger grooves 24. There is also a pair of ventilation apertures located on either side of the mound 22. There are further ventilation apertures formed through the forearm and wrist section of the board. The crux of the ventilating apertures 34 is to provide an escape means for accumulated perspiration. Also, by permitting air to be conducted between the board and the hand, the amount of perspiration should be decreased.
Located within the aft end of the mound 22 is an enlarged ventilating aperture 36. The aperture 36 has for its primary purpose to expose the palm area of the hand. The most likely place for perspiration to occur is within the palm area. Therefore, if the palm area can be kept dry and the amount of perspiration substantially decreased, the patient will be made significantly more comfortable. The size of the ventilating aperture 36 is such that most of the entire palm area is ventilated.
Formed within the edge of the bottom l6 are a first set and a second set of aligned recesses. The first set of aligned recesses is located adjacent the front l8 and includes recesses 38 and 40. The second set of aligned recesses is located adjacent the back end and includes recesses 42 and 44. One function of the recesses 38 and 40 is to connect the cavity 30 to the ambient. The humidity due to the accumulated perspiration is to be permitted to be expelled from the cavity 30 through the recesses. Also, the recesses function to provide air circulation into each of the ventilation apertures 34 and 36.
An additional function of the recesses 38-44 is to facilitate the securing of the patient's arm to the board l0. Adhesive tape is to be conducted through the aligned recesses 42 and 44 and then about the patients forearm to secure the board 10 to the patient's arm. The adhesive tape 46 is shown in phantom in FIG. 1. Similarly, adhesive tape 48 is to be conducted through the recesses 38 and 40 and about the patient's hand in the area of the finger joints to also secure the front portion of the board I0 to the patients hand. Because the adhesive tape is positioned within the recesses, the board 10 will lie flat on any flat surface.
When it is desired that the patient have a needle injected into the patients bloodstream and held for a period of time, one of the patient's hands and forearm is placed upon the board and bound thereto by the use of adhesive tape strips 46 and 48. Because of the mound 22, the veins in the back of the persons hands are positioned straight and accentuated out of the skin. This makes the insertion of the needle easier and less likely to cause unwanted injury. Also, with the needle inserted it tends to be retained parallel to the vein which is the preferred position of the needle.
Because both the forearm section and the upper hand section is bound to the board, it is impossible for the wrist to bend. The patient can move his hand and his arm and the board, but cannot bend his wrist. It is in the bending of the wrist that the needle 32 is likely to be moved and puncture the inner side of the vein.
When it is desired to take the patient off intravenous feeding, the needle is removed and the board is then discarded. Because of the inexpensiveness of the board 10, it can be changed on a daily basis with the old board being discarded and a new one employed. The board of this invention can be constructed to include a bacteria static substance which is to kill bacteria on the surface of the board. This is to keep the surface free of living organisms thereby keeping the board sanitary. An example of such a substance would be benzylconium chloride or various alcohol compounds.
The board of this invention can also be used as an arterial board. At times it is desirable to place a needle within an artery and a desirable place to make contact with an artery is through the underside of the wrist into the arterial artery. The normal procedure to facilitate inserting of the needle in the artery is to bend the wrist which tends to push the artery toward the skin surface and thereby facilitate insertion of the needle. When the needle is inserted, the wrist is then relaxed and the hand is permitted to be located in the normally straight extended position.
In order to use the board 10 of this invention as a arterial board, reference is to be had in particular to FIGS. 6 and 7 of the drawings. Board I0 is to be turned over so that the mound 22 will be positioned against the supporting surface. The upper portion of the mound 22 just forward of the enlarged ventilating aperture 36 is to be slightly flattened to facilitate positioning of the board 10 on the supporting surface. The patient is to place the backside of his hand within the cavity 30 as shown in FIG. 7. A cut-out section 50 is formed within the front end 18 of the board so that the patients fmgers are positioned within the cut-out section 50 to make the patients hand as comfortable as possible.
Intermediate the front end and the back end of the board 10 is a flattened area 52. A wedge 54, which has a smooth upper contoured surface and a lower flat sur face, is to be positioned upon the flat surface 52. The wedge 54 functions to push upwardly the wrist of the patient to facilitate the insertion of the needle into the arterial artery. Once the needle is inserted, the wedge 54 is removed and the patients hand and arm are permitted to relax upon the underside of the board 10. Adjacent the back end of the board on the under surface of board is a shallow longitudinal recess 60. The function of the recess 60 is to provide comfort for the patient's forearm when located in contact with the board 10.
The normal procedure for the using of the arterial board would be to initially locate the patients hand within the cavity 30 and a strip of adhesive tape 56 would be wound about the patient's hand and in cooperation with the aligned recesses 38 and 40. The wedge 54 would then be located under the patients wrist with the forearm section of the patient still being in contact with the aft end of the board 10. The needle would then be inserted within the arterial artery. The wedge 54 would then be removed and discarded. The patients hand is then relaxed against the board and a strip of adhesive tape 58 is positioned about the arm in the area of the aligned recesses 42 and 44.
It is desirable for the board 10 to be electrically conductive so any static charge will be dissipated. For this purpose, a metallic electrically conductive tape 62 is attached to upper surface of the board 10. The patients hand will always be in contact with some part of the tape 62 to dissipate any accumulated static charge from the paticnt's body. One end of tape 62 extends over protuberance 64 formed on the bottom side of board. The height of protuberance 64 is so that the tape 62 will contact the supporting surface (such as the operating table) and therefore provide a continuous electrical ground. The height of protuberance 64 is slightly greater than the edges of the board 10.
The other end of tape 62 is attached in a similar manner to a protuberance 66. Protuberance 66 is also slightly raised in respect to the edges of board 10. Due to the electrical contact points fore and aft provided by protuberances 64 and 66, if the board is tilted, a continuous electrical ground is still maintained because at least one of the protubcrances will be in contact with the supporting surface.
instead of the tape strip 62, it may be preferable to employ a strip of electrically conductive paint. Also, a coating of material may prove to be satisfactory such as the benzylconium chloride previously mentioned.
When the board 10 is used as an arterial board, the patients body will be in continuous contact with at least one of the protuberances 64 and 66. The tape 62 located upon the top surface of board 10 will then be in contact with the supporting surface completing the electrical ground.
