Abstract

This model includes parameters measured and evaluated by different measure units and scales of values, reported on different graduated scales (13). Graduated scales are adapted to a rectangle (horizontal minor sides, vertical major sides) in a way that inferior and superior limits of normality of these parameters correspond respectively to the left (1) and right major sides of the rectangle (3). The value of the examined parameter is reported on the corresponding graduated scale by a marker (point, cross, etc.) (12), put in the position corresponding to numeric value of parameter. Therefore it is possible to carry out a qualitative evaluation of parameter (15). Marker of alterated parameters could be coloured to enhance better altered values. Numeric value and measure unit (11) of the examined parameter are reported in a square (10) consenting a contemporary quantitative evaluation (14).

Description

DESCRIPTION

DEVICE FOR DISPLAYING PARAMETERS IN SUCH A WAY THAT A FAST EVALUATION OF THESE PARAMETERS CAN BE OBTAINED

Technical fields.

This model is applicable in medical field for rapid visualization and evaluation of hematologic parameter, by clinical physician, anaesthetist and surgeon. This model is even applicable in field of engineering and in whatever field in which parameters, measured by numeric values in different scales and measures, should be contemporaneously evaluated.

Background art

By now single hematologic parameter are expressed in numeric values put in a column while range of normality is reported on the right sideexpressed in numeric values

Models are available to report an asterisk near that parameters whose values are out of the range of normality wheteher in defect or in excess

Disclosure of invention.

This model includes parameters evaluated by different measur units and scales of values, reported on different graduated scales [Fig. 5: (13)].

Scales are adapted to- a rectangle (horizontal minor sides, vertical major sides) in a way that inferior and superior limits of normality of these parameters correspond respectively to the left [Fig. 5: (l)]and right major sides of the rectangle [Fig. 5: (3)]

The value of the examined parameter is reported on the corresponding graduated scale by a marker (point, cross, etc) [Fig. 5: (12)], put in the position corresponding to numeric value of parameter.

In this way numeric values are converted in graphic symbols or markers (points, cross, etc): single values are adapted to an unitary pattern that lets the immediate evaluation of that values whether they are normal (inside the rectangle) [Fig. 5: (2)] or they are out of the range of normality (out of the rectangle) [Fig. 5: (5), (7), (9)].

The grade of variation of measured parameter, from inferior or superior normality limits, should be as substantial as marker should be near to left or right limit of scale [Fig. 5: (5), (7)].

Markers of altered parameter could be coloured [Fig.4] to enhance better altered values and to reduce time of examination and evaluation of parameter reported on the model

In medical field this model lets to evaluate which hematological parameters are normal and the ones which are altered with a quick look it's possible to exclude by a more in-depth exam, the normal values put inside colored rectangle [Fig. 5: (2)], and to enhance the altered values in defect (part of the scale to the left of the left major side of the rectangle) [Fig. 5: (9)] or in excess (part of the scale to the right of the right major side of the rectangle) [Fig. 5: (5), (7)] Furthermore it's possible to enhance, by a rapid look, the grade of value alteration of the parameter in exam (minor or major proximity to left or right side of corresponding scale [Fig. 5: (5), (7)].

On the right side there is a square [Fig. 5: (10] in which is precisely reported the numeric value [Fig. 5: (11)] useful for a contemporary quantitative evaluation of the parameter and for forensic medical purposes.

This model is useful in medical field for a rapid visualization and evaluation of hematological parameter:

1) in condition of hospital emergency, reducing time of diagnostic evaluation and intervention; 2) in daily control and updating of hospital ward, during which the physician has to controle 15-20 or more blood tests of different patients by facilitating the physician in reducing time of control and updating of the ward;

3) in medical private field to consent to private institutes, that makes blood tests, to offer another service to his own client whether if he is a physician or a patient;

4) in medical extrahospital private field to consent to physician the evaluation of blood tests of his own patient in a short time;

5) to consent to non-physician patient, who underwent to blood test, to obtain informations, without considering scale values or measur unit, about the rilevation of normal or abnormal values of his hematological parameters and about the grade of this abnormality.

Furthermore the pharmaceutic company which has the exclusive utilizzation of this model could pubblicize it on television contrarily to the reagent used for blood tests. The pharmaceutic company can connect the grant (to pubblic or private companies) to use this model to the one to use their reagents for blood tests by increasing the sales of their reagents.

Brief description of drawings

Fig. 1 is an example of the model for rapid viasualizzation and evaluation of human blood test. Parameters in exam and the abbreviations in the square at the left of the scales are used purely for example. Here we report the abbreviations and the corresponding name of the parameters used only for example in Fig 1

Glyc = glycaemia, Creat = creatinine, Tot Prot = Total Proteins, Album = Albumin, Ammon = seric ammonium, Tot Bil = Total Bilirubin, Conj Bil = 75 Conjugated Bilirubin, Unconj Bil = Unconjugated Bilirubin, AST and ALT = Transaminase, CPK = Creatin- PhosphoKinase, LD = Lactid Dehydrogenase, CHE = Colinesterase, AcPh = Acid Phosphatase, AlPh = Alcalyne Phosphatase, Na = Sodium, K = Potassium, Ca = Calcium

80 Fig. 2 is another example of the model for rapid viasualizzation and evaluation of human blood test Parameters in exam and the abbreviations in the square at the left of the scales are used purely for example Here we report the abbreviations and the corresponding name of the parameters used only for example in Fig 2

MCV = Medium Corpuscolar Volume of erythrocyte, MCH = Medium

85 Coφuscolar Hemoglobin, MCHC = Medium Coφuscolar hemoglobin concentration, Hb = Hemoglobin, Hct = Hematocrit, Neutro = Neutrophilus leukocyte, Eosino = Eosinophilus leukocyte, Baso = Basophilus leukocyte, Linfo = Lynphocyte, Mono = Monocyte, PT = Prothrombine Time, PTT, Partial Thromboplastin Time, TT = Tho bine Time, Fibrin = Fibrinogen, Antitrom III = Antithrombine III

Fig.3 shows the application of markers (in this case points) to the model reported in Fig 1 Marker, expressing the value of a parameter, is put on the scale of corresponding parameter and in a position corresponding to its numeric value In the square put on the right is reported the precise numeric value of the parameter, for a

95 contemporary qualitative and quantitative evaluation worth for forensic medical puφose In Fig. 4 markers of altered parameters are coloured to enhance better altered parameter and their values.

100 Fig. 5 (scale 1 : 1) reports explicative notes about Fig. 3 and puts in evidence the advantage of this model. Particolarly it's evident how it's possible to point out, by a quick look, not only normal values (2) or in defect /excess altered values (5), (7), (9), but also values at normality inferior or superior limit (6) (8) and the grade of alteration of alterated parameter (5) (7).. 105

Best mode for carrying out the invention.

Models of rapid visualizzation and evaluation must be printed a part, and distributed to istitutes which perfoms blood tests.

Markers have to be put by a printer connected to a computer: this computer 110 contain a program which convert the numeric value ofan examined parameter, digitated by an operator, in a marker put on a corresponding scale and in a position corresponding to digitated numeric value.

Industrial applicability

115 As reported in the paragraph "Disclosure of invention", the pharmaceutic company which has the exclusive utilizzation of this model could pubblicize it on television contrarily to the reagent used for blood tests. The pharmaceutic company can connect the grant (to pubblic or private companies) to use this model to the one to use their reagents for blood tests by increasing the sales of its reagents. Furthermore

120 the pharmaceutic company could improve the sales of instruments for blood tests.
