(Cl. 128-2)

1 My present invention relates to an instrument for use in testing the pH value of body canal liquids by means of a paper strip treated to change color when moistened by such a liquid to indicate its alkaline or acid state. In the diagnosis, treatment, and research of various diseases and conditions, it is important for the doctor to know what pH values are present in a body canal. For example, some vaginal diseases can be effectively treated only by establishing a predetermined pH value in that canal. The normal pH of that canal varies in different sections thereof and, as a consequence, both during diagnosis and treatment, it is necessary for the doctor to test the pH value of a predetermined section of it. A broad objective of my invention is to provide an instrument to enable such pH testing to beeffected easily, quickly, and accurately. I accomplish that objective by means of an instrument having a head including a convex contact portion and means associated with the head to receive the ends of the test strip thereby to lock it against the contact portion. The instrument also includes a supporting shank of sufficient length to enable the head to be inserted, usually through a speculum, into the canal and to be passed therealong and its strip covered bearing portion brought into contact with that part of the canal, the pH value of which is to be tested. Another objective of my invention Is to further increase the ease and accuracy of such pH testing by providing a unit attachable to my instrument carrying a movable color chart and indicia relating to its interpretation so that the chart may be moved adjacent and relative to the moistened test strip to facilitate color comparison. In the accompanying drawings, I have shown an illustrative embodiment of my invention from which these and other of its novel features and advantages will be readily apparent. In the drawings: Fig. 1 is a side view of an lllustrative embodiment of my invention. Fig. 2 is a top plan view of the instrument shown in Fig. 1, and Figs. 3 and 4 are partly broken away top and side views, respectively, of an illustrative attachment for the instrument for use in determining the pH value of the tested area by a comparison of the color of the test strip with those of the color chart. In the embodiment of my invention shown in the drawings, I have indicated a head I 0 having a convex bearing or contact portion and having,

at one end, a supporting shank II . The shank II has reversely disposed bends 12 and 13 establishing an intermediate part 14 and an end part 15 terminating in a handle 16. It is essential that the head I 0 have a contact portion of a generally convex form and in order that such portion may be of substantial length and relatively light in weight, I prefer that it be narrow, of arcuate shape, and decrease in thickness towards its free end or tip which is provided with a transverse slit 17. Preferably, the tip terminates short of the dotted line 18, which represents the path of the shank part 14 as my instrument is inserted into or withdrawn from a canal. Adjacent the rear end of the head 10, I provide my instrument with a lip 19 which overlies the rear part of the convex contact surface of the head to anchor one end of a paper strip 20, the other end of which is securely caught in the slit ll thereby to provide means to attach the strip 20 and hold it in place, firmly backed by the contact portion of the head I 0. The strip 20 is of paper stock, sensitized to change color in predetermined relation to the relative acidity or alkalinity of the liquid with which it is moistened. For most uses, an instrument in accordance with my invention is used with a speculum to facilitate both the entrance of the instrument into a canal and the illumination and examination of that canal. In this connection, it will be noted that the handle 16 is so disposed that the hand of the doctor or nurse by which the instrument is held and guided, does not block visibility of the canal or the relation of the head thereto. With the instrument, as thus described, any selected part of a canal may be accurately contacted by the strip 20 and moistened by its mucous coating. The moistened strip 20 changes color and the pH value of the canal, as represented by the liquid in the tested zone, may be determined by comparing its color with a color chart having associated with each of its color shades, the pH value represented by that color or shade thereof. In order that such color comparisons may be made with maximum convenience and accuracy, I have shown a comparator unit, generally indicated at 21 , that is attachable to the instrument after a test has been made. The unit 21 consists of a cylindrical •casing 22 having a disc 23 rotatably housed thereby. The side of the casing 22 is open as at 24 so that the periphery of the disc 23 may be digitally engaged and rotated. The upper surface of the disc 23 is provided with a plurality of colored panels 25 adjacent its pe-
2,664,879
3 riphery and inwardly of each panel 25 is the numerical designation of the pH value of that color. I provide the casing 22 with a window 26 preferably of the same size and shape as each of the panels 25 and having a notch-like part 21 through which the numeral designation of pH value is visible when no part of an adjacent panel is visible. In order that the comparator unit 21 may be quickly and easily attached to or detached from my instrument, I provide the instrument with a rib portion 28 which may conveniently include the lip 19 and which has recesses 29 and 30. Centrally of the casing 22 is a split leg 31 having a resilient friction fit in the recess 29 and adjacent its periphery is a leg 32 disposed to enter the recess 30 to hold the attached unit 21 against rotation when attached to the instrument. It will be apparent that the comparator unit 2 I greatly facilitates the determination of the pH value of the test strip 20, for, when attached t o the instrur.J.ent, each panel, when visible through the window 26 , is located adjacent and in alinement with an end of the strip 20 . A single color comparator unit 21 can, of course, be used to service a number of instruments. From the foregoing, it will be appreciated that my instruments are simple and inexpensive to manufacture and are well adapted to meet the requirements of the doctor in diagnosis, treatment, and research of diseases and conditions of body canals. What I therefore claim and desire to secure by Letters Patent is: 1. An instrument for use in testing the pH value of body canal liquids with a paper strip sensitized to change color, when wetted by a liquid, to indicate its relative acidity or alkalinity, said instrument comprising a relatively long and narrow arcuate head, a shank connected at one end to the rear end of said head and at its other end including a handle, the front end of said head having a transverse slit to anchor one end of said strip, and said instrument including a lip overlying the rear end of said head to lock the anchored strip against the convex surface of said head. 2. The instrument of claim 1 in which the shank includes a first bend adjacent the head and a second bend adjacent the handle and spaced from the first bend to establish an intermediate part of substantial length, each bend being in a direction opposite to the other. 3. An instrument for use in testing the pH value of body canal liquids with a paper strip sensitized to change color, when wetted by a liquid, to indicate its relative acidity or alkalinity, said instrument comprising a relatively long and narrow arcuate head, a shank connected to said head and including a handle, the front

Pig. 1 is a plan view showing a folder housing a file of twelve sheets corres::x>ndlng to the diJferent months of the year, said sheets embodying one form of the present invention and being shifted to the right in echeloned arrangement so as to expose the month column alongside of each other at the left side of the sheets; FJg. 2 is a view similar to Pig. 1, Ulustrating the sheets in echeloned arrangement, but shifted 10 toward the left so as to expotie the right-hand columns on the sheets alongside of each other; Pig. 3 is a view similar to Pig. 1, representing two files built up for only a few months of the year, and lliustrating how the sheets for suc16 ceeding months are applied to build up a com-' plete file far all the months, or longer periods, if desired. · Pig. 4 is a fragmentary top edge plan view, with the thickness of the sheets . exaggerated 20 so as to Ulu'!trate the connecting means more clearly, oi the folder shown in Pig. 1; Pig. 5 is a view s1milar to Pig. '· and mustrating the sheet displaced to the right in echelon with respect to the backing sheet; 25 Pig. 6 is fragmentary top edge plan view of several sheets, the thickness of which is exaggeratt'd for the sake of clarity, Ulustrating an· other form cf the means that may be used for connecting the sheets; 30 Pig. 7 is an enlarged front elevation of a single sheet lliustrating one preferred form only of the arrangement of scored and perforated lines employed in the present invention; Pi£. 8 is a fragmentary rear elevation showing 35 the reverse side of the sheet illustrated in Pig. 7; Pi~:. 9 is a perspective view -:>f the sheet of Pig. 7 mustrating the means or tearing and folding the upper edge in accordance wtth the present tnvention; 40 Pig. 10 is a fragmentary front elevation of a sheet simllar to that of Flg. 7, but lllustrating a modified form of the invention; Pig. 11 is a fragmentary side edge elevation ot several sheets, exaggerated in thickness, and 46 lllustrating t he means of connecting sheets as shown in .Fig. 10; and Pig. 12 is a fragmentary front elevation of sheets assembled as shown in Pig. 11. Referring now more particularly to the draw150 ings by reference numerals, the sheets, generally indicated by the numeral Ill in the various figures, are preferably or a type commonly provided with a row of perforations 16 along the top edge enabling them to be inserted in 61 1~-le'-f binders. However, it Ia not essential
ticularly it relates to comparative data files of a type generally mustrated 1n United States Patents Nos. 2,295,951 and 2,295,952 issued to Cedric F. Gove and Jesse M. Jones, Septembel" 15 15, 1942. In files of this general type, each sheet carries a column at each edge, and in which entries are made so that each sheet corresponds to a certain period of time. The sheets are then shifted lateral]y into an- echeloned arrangement, so that the corresponding columns adjacent tht. same edge of the Juxtaposed sheets are exposed alongside of each other. In thiS way monthly totals in a business, or slmllar entries over a considerable time can be displayed for comparison alongside of each other. One of the objects of the present Invention is to provide a file for housing sheets contalning entries extending over dl.1ferent periods of time, and which are connected together 1n such a way that they can be moved laterally into an echeloned position so tha.t entries on corresponding columns and lines of the dUierent sheets can be seen and compared simultaneously. Another object of this Invention is to provide a simple and effective guiding means for connecting the sheets and which will keep them properly aligned with each ol.her in a direction across the sheets, when they are fully extended and may number twelve or more to cover a period of time such as a year. Another objec~ resides ln the construction of a means for connecting the sheets together which is formed as an Integral part of each shee~. and which provides emclency In operation as well as economy in manufacture. _ Another object resides In the provision of non-metalllc connections b~tween the sheets enabling them to be held in juxtaposed position and extended in echeloned arrangement whrn desired. An advantage arising from the use of a connecting means which is non-metallic in character is readily apparent since the present scarcity of metals has made It practically impossible to secure metals for clips or spUn~ of a type heretofore used and as disclosed in the above named patents. Other objects and advantages of this inven· tion wUI be apparent from the following description, the appended claims, ana the accompanying drawings.
