Definitions
- the pressure measuring device is accommodated in a usually cup-shaped housing and fastened therein to one of the parts of the housing.
- This housing also houses the measuring scale through which the measuring shaft extends.
- the Meß2eiger is mounted on the measuring shaft above the scale.
- the measuring scale and the measuring pointer are covered by a transparent cover plate which is inserted at the upper edge of the housing and which at the same time also closes the interior of the housing.
- the housing In the area of the floor and the transition of the floor into the peripheral wall, the housing inherently has a relatively high dimensional stability, so that in this area the deformations caused by the fall generally remain relatively low. The situation is different when the housing opens in the area of its upper edge where the measuring scale and the cover plate are inserted. At the same time, there is a risk that the measuring scale and the cover plate will be damaged in addition to the housing itself.
- the measuring scale can be bent or warped. This deformation of the measuring scale can go so far that the measuring pointer can no longer move freely over the measuring scale.
- the measuring scale can also jump out of its holder.
- the cover plate In the event of a particularly strong impact, the return fields of the measuring mechanism, which are designed as a spiral spring, can also be damaged if, for example, one or more of their turns overlap and then get caught. at All of these damage or even destruction of individual parts, the entire blood pressure monitor is usually unusable.
- the object of the invention is to design a blood pressure measuring device in such a way that the damage or destruction resulting from a case is at least reduced, if not avoided entirely.
- the peripheral wall of the inner primary housing cannot hit when the blood pressure measuring device falls onto a hard surface. It cannot be deformed as a result.
- the risk that the measuring mechanism housed in the primary housing and its parts are damaged is virtually eliminated.
- the primary housing is pressed in in the region of its upper edge, where the measuring scale and the cover plate are attached. Therefore, these parts can practically no longer be damaged.
- Claim 2 facilitates a simple connection of the pressure measuring device to the other parts of the blood pressure measuring device arranged on the outside of the bottom of the housing.
- Claim 3 facilitates a simple connection of the pressure measuring device to the other parts of the blood pressure measuring device arranged on the outside of the bottom of the housing.
- the protective ring arranged at the upper edge of the protective housing covers the space between the peripheral wall of the primary housing and the peripheral wall of the protective housing to the outside.
- penetration of dust and dirt into this intermediate space is at least greatly reduced, if not completely ruled out.
- the fact that the protective ring extends inwards to at least the edge of the primary housing, if not slightly beyond it, also protects the upper edge of the primary housing with the cover plate used there and the measuring scale used underneath it from the front side of the blood pressure monitor.
- Claim 5 reduces the risk of damage to the protective ring, because the tapering outer side of the protective ring means that there is no longer a sharp edge that would be exposed to damage when struck on a hard surface.
- This shape of the protective ring increases the impact area and thus reduces the surface load at the impact point. This also makes it easier to roll the housing off the ground, which also helps to reduce peak loads.
- the mounting of the protective ring is simplified and facilitated by an embodiment of the blood pressure measuring device according to claim 6.
- the elastic intermediate ring between the protective ring and the protective housing absorbs part of the impact energy in the event that the housing of the blood pressure measuring device hits the hard ring with the protective ring first. This also significantly reduces the risk of damage to the parts of the blood pressure monitor.
- Figure 1 is a partially sectioned view of a housing of the blood pressure meter, in which most parts of the measuring mechanism are not shown.
- Fig. 2 is a partially sectioned view of the
- Fig. 3 is a view of the housing of FIG. 2 in a
- the blood pressure measuring device 10 shown in detail in FIG. 1 has an at least approximately cup-shaped housing 11.
- the interior 12 of the pressure measuring device of conventional design is housed, of which only the measuring scale 13 is shown in Fig. 1.
- the housing 11 is a type of double housing with an inner or primary housing, which is referred to below as the primary housing 14, and with an outer or secondary housing, which is referred to below as a protective housing 15 because of its special function.
- the housing 11 with its two partial housings 14 and 15 is produced as a plastic molded part in one piece.
- the primary housing 14 is cup-shaped and has a bottom 16 and a peripheral wall 17.
- the protective housing 15 has at least approximately the same shape and also has a bottom 18 and a peripheral wall 19.
- the bottom 18 of the protective housing 15 connects at the same height as the bottom 16 of the primary housing 14 on the outside of the peripheral wall 17 thereof.
- the base 18 is reduced to an annular surface, the radial extent of which is only approximately so is as large as the clear radial extent of the intermediate space 21 between the peripheral wall 17 of the primary housing and the peripheral wall 19 of the protective housing 15.
- the primary housing 14 has a circular-cylindrical through-hole 22 in the circle of its bottom 16, through which the compressed air-carrying parts of the blood pressure measuring device 10 are connected to the pressure measuring device accommodated in the interior 12.
- a shoulder 26 with a flat circular ring surface is provided on the outside in the region of the upper edge. It is delimited on the inside by a circular cylindrical surface 27.
- an annular bead 28 protruding radially outward is formed in the adjoining longitudinal section of the peripheral wall 19, the outside of which has at least approximately the shape of a circular cylinder.
- annular bead 28 protruding radially outward is formed in the adjoining longitudinal section of the peripheral wall 19, the outside of which has at least approximately the shape of a circular cylinder.
- annular bead 28 protruding radially outward is formed in the adjoining longitudinal section of the peripheral wall 19, the outside of which has at least approximately the shape of a circular cylinder.
- an annular bead 28 protruding radially outward is formed in the adjoining longitudinal section of the peripheral wall 19, the outside of which has at least approximately the shape of a circular cylinder.
- annular bead 28 protruding radially outward is formed in the adjoining longitudinal
- the protective ring 31 has a roof-shaped cross section with a different roof surface height.
- the outer roof surface, or briefly the outside 34 of the protective ring 31 has at least approximately the shape of a spherical section.
- the inner side of the roof surface or briefly the inner side 35 of the protective ring 31 has the shape of a truncated cone surface.
- the protective ring 31 extends from the outside of the peripheral wall 19 of the protective housing 15 inwards to beyond the peripheral wall 17 of the primary housing 14, so that it extends from the edge of the peripheral housing wall 17 used cover plate 25 covered in the radial direction around a narrow circular surface. In the axial direction, the edge of the protective ring 31 does not abut the cover disk 25, but maintains a small safety distance from it, so that the protective ring 31 does not immediately strike the cover disk 25 in the event of a possible elastic deformation.
- the protective ring 31 In order that the protective ring 31 can optimally fulfill its function, it is expediently produced from a plastic which has a higher impact and breaking strength than the material of the housing 11.
- the snap lock 29 is designed such that the protective ring 31 can be displaced a small amount in the axial direction relative to the protective housing 15 if it is snapped onto the edge of the protective housing 15.
- a elastic intermediate ring 36 inserted at least in the axial direction. This dampens shocks that may strike the protective ring 31 from above.
- an intermediate ring 16 made of an elastomer can also be used, which because of its material, for example as a metal ring, or because of a separate coloring, has a specific color contrast with the color of the protective housing 15 and / or with the color of the protective ring 31.
- Parts of the blood pressure measuring device 40 which are all not shown, are to be regarded as the same or at least similar to the corresponding parts of the blood pressure measuring device 10.
- the outer and inner dimensions of the housing 41 are practically the same as those of the housing 11. It also has two partial housings, namely the primary housing 42 and the protective housing 43.
- the pressure measuring unit accommodated in the interior of the housing 41 is not connected here to the other compressed air-carrying parts of the blood pressure measuring device 40 via a through hole in the bottom of the housing, but via a connecting line 44 which extends in the area of the peripheral wall 45 of the primary housing 42 and the peripheral wall 46 of the protective housing 43 is arranged.
- This connecting line 44 is formed by a through hole 47 in the peripheral wall 45, by a through hole 48 in the peripheral wall 46 and by a through hole 49 in a material bridge 51.
- This material bridge 51 fills the space 52 all around in the area of the connecting line 47 between the peripheral wall 45 of the primary housing 42 and the peripheral wall 46 of the protective housing 43 and thereby closes the connecting line 44 from the outside.
