Description
- The present invention relates to a dental surgery apparatus.
- There is currently a trend toward significantly high levels of technology in equipment for dental surgeries and treatment centres; doubtless, such a development has been influenced by the growing standards of attainment in professional skills and specialization on the part of dental practitioners by whom odonto-surgical operations are performed on the premises in question.
- Given that such operations can be complex, lengthy and delicate, the dental surgeon needs increasingly to ensure that many of the patient's primary bodily functions can be monitored more effectively, and in real time; this is especially the case where large areas of the oral cavity have to be anaesthetized for an appreciable duration.
- Dental surgery apparatus' with the features of the preamble of
claim 1 are commonly known, as can be derived from US-A-4 013 328. - Accordingly, the object of the present invention is to provide an apparatus such as will allow a dental surgeon, nurse or hygienist to apply sensors simply and swiftly to the body of a patient occupying the chair and thereupon to obtain a full and continuous display of cardiac functions while an operation is performed on the oral cavity of the patient.
- The stated object is solved in a dental surgery apparatus as characterized by the appended claims.
- The equipment of the dentist's chair and its associated apparatus with an electrocardiograph enables to monitor the cardiocirculatory functions of a patient constantly and comprehensively during treatment.
- The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:
- fig 1 illustrates a dental surgery apparatus with electrocardiograph according to the invention, seen schematically and in perspective;
- fig 2 shows a further perspective of the apparatus of fig 1, illustrating variations in the layout of the display and sensors of the electrocardiograph;
- fig 3 is a block diagram illustrating connections between the electrocardiograph and means by which other components of the apparatus are operated;
- fig 4 is a further block diagram illustrating an alternative layout of the electrocardiograph within the apparatus.
- With reference to the accompanying drawings, the components of a dental surgery apparatus according to the invention (figs 1 and 2) include a
frame 1, and achair 2 supported by the frame; the chair in its turn comprises a fully recliningbackrest 3, and preferably, twoarmrests 18 anchored rotatably to the backrest one on either side. - 4 denotes a first vertical column positioned to one side of the
chair 2, which carries aspittoon cup 5 and means 6 of supplying water, typically apipe 20 that terminates in a spout over ashelf 21 serving as a stand for a drinking glass (not illustrated); the samefirst column 4 also supports two arms denoted 30 and 7, which are anchored pivotably at separate points, positioned in such a manner as to overhang thechair 2, and adjustable for height. - The one
arm 30 supports anoverhead lamp 8, and the remaining arm 7 aconsole 9 carrying a plurality of primary handpieces 10 (illustrated schematically, being conventional in embodiment). - 11 denotes a second vertical column, remote from the
base 1, supporting a plurality of secondary orauxiliary handpieces 12. The apparatus also houses electrical means 31 (see figs 3 and 4) interfaced with hydraulic and pneumatic means 32 and 33, all of which combining to bring about the operation of the various elements mentioned above. - In addition to the components mentioned thus far, the apparatus disclosed, denoted R in its entirety, incorporates an
electrocardiograph 13 comprising aprocessing unit 13u, amonitor 14 by means of which to display the electrocardiographic signal, and a plurality ofsensors 15 for attachment to the body of the patient which are stowed internally of the apparatus when not in use. - In the example of figs 1 and 3, the
monitor 14 is integral with theprocessing unit 13u and mounted to one end of ahorizontal bracket 16 of which the remaining end is secured to thearm 30 carrying thelamp 8; more exactly, thebracket 16 is associated with thearm 30 by way of asleeve 22 ensheathing the pivoted upright member of the arm. - Figs 2 and 4 show an alternative solution in which the
monitor 14 remains integral with theprocessing unit 13u, but in this instance is incorporated into thehandpiece console 9, mounted flush with the screen positioned to occupy one of the horizontal faces of the relative housing. To advantage, the monitor 14 (analog or digital, and preferably the latter) will be one and the same as a display unit already fitted to the most recent generation of handpiece consoles, through which the operator of the apparatus is able to monitor various functions (handpiece speed setting, temperature, disinfection and sterilization cycles, timer, etc.). - Similarly, the sensors 15 (which in the example of the drawings are three in number, i.e. sufficient for the purposes of producing a reliable ECG trace) might be located at different positions on the apparatus R. In one possible solution (fig 1), the
sensors 15 are concealed inside the firstvertical column 4 and accessible through thepanel 4a facing thechair 2; in effect, thesingle sensors 15 will be associated with flexible connection means taking the form ofconventional sheaths 23 covering the relative conductors, which are retractable into the column and therefore of variable length in such a way as to permit of being drawn out at the moment of use and applied to the appropriate points of the patient's body, namely the wrists and throat. - In a second solution, the
sensors 15 are stowed in at least one of the pair ofhorizontal armrests 18 associated with thebackrest 3, passing throughrespective collars 24 afforded by thearmrest 18 in question; likewise in this instance, thesensors 15 are attached to flexible connection means and can thus be drawn out to the appropriate length from thearmrest 18 at the moment of application to the patient. - Yet another possible arrangement is illustrated in fig 1 (see inset P); in this instance, the
single sensors 15 are associated with respective plugs S insertable individually into corresponding contact sockets C afforded by thecolumn 4, and removable thus from the apparatus altogether. The advantage of this arrangement is that it allows for a safer and more convenient disinfection and sterilization of thesensors 15 following treatment on a single patient. - The
electrocardiograph 13 might also be equipped with accessories, for example aprinter 25 by means of which to produce hard copies of the ECG traces generated by theprocessing unit 13u. - Naturally enough, the
processing unit 13u might also be incorporated directly into theelectrical means 31 of the apparatus, thereby rendering the design generally more compact and more complete and achieving greater reliability in operation of theelectrocardiograph 13 as a whole. - Thus, with a dental surgery apparatus as disclosed, it becomes possible to provide an additional and more complete back-up in monitoring the principal bodily functions of a patient during operations of a certain complexity; moreover, the architecture of the essential chair and column structures remains unaffected, and the proven practical and ergonomic advantages of the modern apparatus are therefore retained intact.
