Definitions
- Medical device housing for the medical device and cover for the housing
- the present disclosure relates to a medical product. Furthermore, a housing for the medical product and a cover for the housing are disclosed. A mechanical display device is provided on the housing and/or the cover and is configured to visually and/or haptically indicate the current charge status of a battery compartment formed by the housing from outside the medical product, even when the access is closed.
- no battery meets the requirements for resistance to sterilization with hot steam at high temperatures in the range of 134°C.
- the sterile use of batteries in the operating room is currently not possible.
- the increase in battery performance through the use of lithium-ion technology also entails an increased risk of fire and explosion due to the reactivity of lithium when batteries are subjected to sterilization with hot steam. Furthermore, this risk also exists with empty or defective batteries.
- the battery must be removed from a medical device prior to reprocessing and sterilization to prevent it from being subjected to a reprocessing cycle (CSSD, RUMP).
- CSSD reprocessing cycle
- RUMP reprocessing cycle
- a technique is to be provided that enables reliable detection of whether a battery, in particular a rechargeable battery, is incorporated into a medical product.
- a medical device is intended and designed for a sterilization process.
- the medical device may be a medical hand-held instrument.
- the medical product comprises a housing that forms a battery receiving compartment that can be loaded with a battery unit (battery block) via an access (loading access).
- the battery unit can be received in the battery receiving compartment, preferably with little or almost no play.
- the battery unit (battery block) can comprise a control unit (electrical control) for the medical product or for its motor unit (drive motor).
- the battery unit also has a battery/rechargeable battery, preferably a secondary battery, such as a lithium-ion battery.
- the medical product further comprises a cover (flap, hood, closure, cap, etc.) that is designed and configured to close the access when engaged with the housing.
- the cover preferably completely encompasses the housing around the access.
- the cover In a closed state of the cover, the cover is preferably releasably/openably engaged with the housing.
- the medical device further comprises a mechanical display device provided on the housing and/or the lid and designed to visually and/or haptically indicate the current charge level of the battery compartment from outside the medical device, even when the access is closed. This allows the charge level to be reliably detected visually and/or haptically, thus avoiding sterilization of the medical device containing the battery unit.
- the mechanical display device can be provided and configured to provide a visually and/or haptically recognizable display of the current charge level of the battery compartment mechanically, i.e., independently of an electrical power supply, even without the provision of electrical power. This enables a reliable display of the charge level even when the battery is discharged. Consequently, the risk of sterilization of the medical device with the battery unit installed is reduced.
- the mechanical indicator can be or have a viewing window through which the battery compartment can be visually inspected from outside the medical device. This allows for easy verification of the battery charge status. More preferably, an indicator, such as a color marking, may be attached to the battery unit, which is visible through the viewing window.
- the mechanical display device can have a display element that is visually and/or haptically recognizable from outside the medical product and a trigger section of the display element and/or a trigger mechanism that is at least partially arranged in the battery compartment and operatively connected to the display element. Accordingly, the display element can indicate a loading status.
- the display element is actuated or triggered by the trigger section and/or the trigger mechanism.
- the display element can enable different color markings, e.g., green for not loaded and red for loaded.
- the display element can protrude from the housing and/or the lid for the purpose of haptic detection when loaded with the battery unit.
- the trigger section of the display element and/or the trigger mechanism can extend at least partially into a loading/removal path of the battery unit, such that the trigger section of the display element and/or the trigger mechanism is actuated by the loading/removal process of the battery unit itself. Consequently, the trigger section and/or the trigger mechanism enable automatic actuation of the display element, thus enabling a reliable display of the charging status.
- the (purely mechanical) display element can be a plunger (for example in the form of a pin, a tongue, a flag, etc.) to implement the mechanical display or can consist of such a plunger.
- the plunger can be designed and configured to protrude or protrude from the housing and/or the cover when a battery unit is accommodated in the battery compartment.
- the plunger or a trigger section of the plunger can be displaced or shifted to the outside of the housing and/or the cover by the battery unit accommodated in the battery compartment.
- the protrusion of the plunger enables a reliable visual and haptic display.
- the display element can also be a flat, plate-like, or shell-like section of the cover or housing, for example, a section of a base surface or base plate of the cover or even substantially an entire base plate of the cover.
- the flat, plate-like, or shell-like section can be extendable and/or retractable with respect to a main section of the cover (cover base body) or the housing (housing base body), i.e., it can protrude or protrude with respect to the rest of the housing or cover, as well as be flush with the rest of the housing or cover, or be accommodated in the rest of the housing or cover for a flush fit.
- a plunger can be coupled directly or indirectly to such a display element.
- the plunger or a trigger section of the plunger can be displaced or shifted by the battery unit accommodated in the battery compartment, wherein the displacement or shifting of the plunger, due to the provided direct coupling, directly leads to a displacement or shifting of the display element, in particular the flat, plate-like, or shell-like section, towards the outside of the housing and/or the cover.
- the plunger or a trigger section of the plunger can be displaced or shifted by the battery unit accommodated in the battery compartment, wherein the displacement or shifting of the plunger, due to the provided indirect coupling, indirectly leads to a displacement or shifting of the display element, in particular the flat, plate-like, or shell-like section, towards the outside of the housing and/or the cover.
- the trigger section can be a plate that is displaceable or slidable relative to a wall of the housing and/or the cover, in particular parallel.
- the plate can be formed integrally with the plunger.
- the plate can engage with the plunger.
- the plate can be congruent with the access in order to reliably close the access within the cover.
- the plate can also be arranged instead of the plunger or in addition to this by the battery unit accommodated in the battery compartment to the outside of the housing and/or the cover.
- the trigger mechanism can be or comprise an elastic element.
- the indicator element e.g., the plunger
- the elastic element can be a spring. More preferably, at least one conical coil spring can be used for preloading. Conical coil springs offer the advantage of being highly compressible. The preload ensures that the indicator element, e.g., the plunger, only protrudes from the housing/cover when the battery unit is inserted, thus preventing an incorrect display when the battery unit is not present.
- the trigger mechanism can also comprise a plurality of elastic elements, in particular springs, whose effect is coordinated with one another in such a way that the indicator element is displaced or shifted toward the outside of the housing and/or the cover when the battery unit is provided or arranged in the battery compartment, and that the indicator element is not displaced or shifted toward the outside of the housing and/or the cover when the battery unit is not provided or arranged in the battery compartment.
- the trigger mechanism can also include additional elements such as a pressure plate or a guide screw.
- the plunger is not the indicator element but is indirectly coupled to the indicator element, the plunger can also be part of the trigger mechanism.
- the indicator element can be located in the lid. This offers the advantage that the lid can be retrofitted with the indicator element cost-effectively on existing products. Using the plunger also ensures that the medical product cannot be placed on the lid without tipping over, thus preventing the indicator element from being accidentally covered.
- One dimension of the plate can correspond to a rim surrounding the access and formed by the housing. Consequently, the access can be reliably closed within the cover.
- a sealing element which has the dimensions of the plate and thus of the edge around the access, can be arranged on a side of the plate facing the battery compartment. The sealing element can then be arranged between the edge and the plate when the lid is closed. This ensures a good sealing effect.
- the sealing element can allow for a different degree of compression. In the event that no battery unit is accommodated in the housing, the sealing element can be more strongly compressed, for example due to preload. If the battery unit is accommodated in the housing and the plunger or the plate is displaced towards the outside of the lid, the sealing element can be less strongly compressed.
- the sealing element can be made of silicone for this purpose.
- the plunger and the plate can be designed such that the plate is not displaced too far towards the outside of the lid when the battery unit is accommodated, in order to ensure contact between the sealing element and the plate and the edge even when the battery unit is accommodated
- the plunger can extend through the sealing element. Consequently, the plunger can come into contact with the battery unit, so that it and/or the plate is displaced or shifted towards the outside of the lid. Consequently, a reliable mechanical display towards the outside is ensured.
- a display element directly or indirectly coupled to the plunger for example in the form of a plate-like, planar, or shell-like section, a displacement or shifting of the display element towards the outside of the lid is carried out, enabled, or released by the plunger, thus correspondingly also ensuring a reliable mechanical display towards the outside.
- the plunger can either engage around the sealing element or engage behind the sealing element toward the battery compartment and enclose it between itself and the plate. Consequently, a reliable seal of the battery compartment is achieved in the area of the plunger.
- the battery unit can have a control unit and a light-emitting element.
- the light-emitting element can be a light-emitting diode.
- the control unit can be configured and designed such that it switches on the light-emitting element when the battery unit is accommodated in the battery compartment.
- the display device can be or have a viewing window or light guide.
- the viewing window can be arranged in the cover or the housing separately from the plunger. Preferably, the viewing window can be formed through the plunger along its extension direction.
- the viewing window can be made of Plexiglas and inserted into a hole made through the plunger and glued to it. Accordingly, the viewing window has a great length, preventing germs from escaping from the battery compartment along a contact surface between the plunger and the viewing window.
- the light-emitting element can then be arranged in the region of the viewing window, so that light emitted by the light-emitting element passes through the viewing window to the outside of the housing and/or the cover.
- the light-emitting element and the viewing window can be arranged axially. It can also be provided that the light emitted by the light-emitting element passes through the viewing window and a fluorescent plate to the outside of the housing and/or the cover.
- the fluorescent plate can be the outwardly projecting display element. Consequently, a visual display of the display device is enhanced by the emission of light.
- the display element can be a flat or plate-like or shell-like section of the cover or the housing, preferably a plate, particularly preferably a, in particular fluorescent, base plate of the cover.
- the display element can be directly or indirectly coupled to a plunger. If the plunger is the display element or is directly coupled to the display element, the plunger or the display element can be damaged if the display element is impacted or if the display element hits a surface.
- an indirect coupling of the plunger to the display element particularly in combination with an impact protection mechanism or an impact protection device for resiliently absorbing an impact of the display element or a shock to the display element, according to the disclosure particularly preferred.
- the plunger can be provided and configured to be displaced or shifted by a battery unit accommodated in a battery receiving compartment, wherein the displacement or shifting of the plunger indirectly leads to a displacement or shifting of the display element towards the outside of the housing or the cover, in particular enabling the displacement or shifting of the display element towards the outside.
- a particularly preferred embodiment is characterized in that the displacement or shifting of the plunger by the battery unit accommodated in the battery receiving compartment leads to a displacement or shifting of a pressure plate and to a compression of a preferably central, elastic spring element, wherein a guide screw which is movable relative to the pressure plate and is firmly connected to the display element is accommodated in a through-bore of the pressure plate, and wherein the displacement or shifting of the pressure plate and the compression of the elastic spring element releases a travel or shifting path of the display element and the guide screw, wherein the displacement or shifting of the display element and the guide screw is brought about by at least one further elastic spring element.
- An optionally provided impact protection mechanism or an provided impact protection device for resiliently absorbing an impact of the display element or an impact on the display element preferably has at least one compressible elastic element and a guide screw which is fixedly connected to the display element and is movable in at least one direction.
- a housing for a medical product or a medical product as described above.
- the housing forms a battery compartment that can be loaded with a battery unit via an access.
- a mechanical display device is provided on the housing and is designed to visually and/or haptically indicate the current charge status of the battery compartment from outside the medical device, even when the access is closed. Consequently, the housing enables a reliable indication of whether the battery unit is accommodated therein. It should be noted that the housing can be further developed according to the aspects described above in connection with the medical device.

- the battery unit 12 comprises a battery, preferably a secondary battery, and preferably a control unit for the medical product 1, in particular for its motor unit (not shown).
- the housing 2 defines an access through which the battery unit 12 can be introduced, in particular pushed, into the battery receiving compartment.
- the cover 4 closes the access and can, for this purpose, completely encompass the housing 2 around the access.
- cover 4 can be releasably engaged with the housing 2 when the cover 4 is closed.
- the cover 4 and the housing 2 can be engaged by means of a releasable locking or snap-in mechanism that can be released or released by simultaneous actuation of actuating elements 8 and 10.
- an indicator device is provided in the lid 4, which at least mechanically indicates to an outer side of the lid 4 that the battery unit 12 is accommodated in the battery receiving compartment.
- the indicator element has a plunger 6, which projects from the lid 4 when the battery unit 12 is accommodated and the lid 4 is closed.
- the plunger 6 is displaced or shifted from the battery unit 12 to the outer side of the housing 2, as will be described later.
- a section 7 of the plunger 6 projecting from the lid 4 can be colored with a signal color, e.g., red, and/or have a label.
- the plunger 6 is shown as a circular cylindrical body, but can of course also have another suitable shape, such as a plate-like shape or be directly or indirectly connected or coupled to a plate.
- Fig. 2 shows a detailed view of the cover 4 placed on the housing 2.

- the plunger 6 extends through the sealing element 20 and surrounds the sealing element 24.
- the plunger 6, which is formed integrally with the plate 14, can engage behind the sealing element 20 in the direction of the battery compartment and enclose it between itself and the plate 14. Consequently, a good seal of the battery compartment is achieved.
- the sealing element 20 When the lid 4 is closed, the sealing element 20 is arranged between the plate 14 and the edge 16. In the event that no battery unit 12 is accommodated in the housing 12, the sealing element 20 is compressed in the region of the edge 16 by the conical spiral springs 18. However, in the event that the battery unit 12 is accommodated in the housing 2, the plunger 6 is displaced or shifted by the battery unit 12 towards the outside of the lid 4, so that the conical spiral springs 18 are compressed more strongly and consequently the sealing element 12 is compressed less strongly in the region of the edge 16.
- the length of the part of the plunger 6 that projects beyond the plate 14 towards the battery compartment should preferably be selected such that contact between the sealing element 20 and the plate 14 and the edge 16 is still maintained.

- the display device can have a viewing window 24 through which the light emitted by the LED 22 passes out.
- the viewing window 24 can preferably be formed through the plunger 6 along its extension direction.
- a Plexiglas element can be inserted into a through-opening formed through the plunger 6 along its extension direction and glued thereto. In this way, a viewing window 24 with a long length is achieved, reliably preventing germs from escaping from the battery compartment to the outside.

- the plunger 6 in the embodiment of Figures 7 to 9 is not a display element and is therefore not itself displaced or shifted towards the outside of the cover 4. Instead, the axial end of the plunger 6 facing away from the battery unit 12 is received in a (central) receptacle 31 of a pressure plate 32 such that a movement of the plunger 6 in the axial direction A from the retracted state to the extended state effects or causes a movement of the pressure plate 32 in the axial direction A, which is accompanied by a compression of a (central) elastic spring element 34 arranged between the pressure plate 32 and the cover base body 28, which can be a (conical) spiral spring.
- the pressure plate 32 has at least one through-bore 36 for a guide screw 38, preferably two diametrically opposed through-bores 36 for two guide screws 38, radially on the outside (in the sectional views shown, sections perpendicular to each other are shown to the left and right of the central axis).

Furthermore, the lid 4 also has actuating elements 8, 10, via which a releasable locking or snap-in mechanism, by means of which the lid 4 and the housing 2 engage, can be released or released.
- the base plate 4 is preferably a fluorescent disc or plate, for example made of Plexiglas, so that the light emitted by an LED (not shown) can escape to the outside via the light guide or viewing window 24 and the base plate 26.
- the base plate 26 does not necessarily have to have fluorescent properties, but can also simply be a colored plate, such as a green-colored plate, or can simply have a colored marking or a colored band on the outside.
- the cover element 48 is preferably the same color as the lid base body 28.
- the light emitted by the base plate 26 or the base plate 26 itself differs in color from the lid base body 28 and the cover element 48, the loading state of the battery compartment with the battery unit 12 is immediately apparent from the outside.
- FIGS 8A to 8C show sectional views of the medical product 1, in whose housing 2 no battery unit 12 is accommodated.
- Fig. 8A shows a state in which the housing 2 is being pushed or moved in an axial direction A towards the cover 4, with the aim of bringing the cover 4 and the housing 2 into an engaged state in order to close the access of the battery receiving compartment in which no battery unit 12 is accommodated.
- Fig. 8B shows a state in which the edge 16 of the housing 2 comes into contact with the plate 14 and displaces the plate 14 relative to the plunger 6 and away from the sealing element 20, whereby a compression of the coil springs 18 occurs.
- Fig. 8C shows a state in which the cover 4 is fastened to the housing 2 and the coil springs 18 are compressed between the plate 14 and the cover base body 28.
- the pressure plate 32 together with the plunger 6 is pressed upwards or counter to the axial direction A by the (central) elastic spring element 34.
- the pressure plate 32 presses the guide screw 38 via the screw head section 42 resting on the pressure plate 32 upwards or counter to the axial direction A, whereby the base plate 26 screwed to the guide screw 38 is also pressed upwards or counter to the axial direction A.
- the elastic spring element 46 or the preferably two provided and diametrically opposed elastic spring elements 46 are compressed so that the base plate 26 is completely accommodated in a base plate receptacle 50 formed by the cover base body 28 and is not visible from the outside.
- the cover element 48 is located here essentially on the lid base body 28 and closes the lid base body 28 essentially flush.
- Figure 9A corresponds to Figure 7C and thus shows a state in which the base plate 26 of the lid 4 is in a fully extended state (relative to the lid main body 28) and thus indicates that a battery unit 12 is located in the battery receiving compartment. If, in the state shown in Figure 9A, the medical product 1 with its lid 4, in particular with the base plate 26 and the cover element 48, impacts a surface such as a table or a floor, or if an impact is exerted on the cover element 48 or the base plate 26, this impact or this impact is absorbed in a suitable manner (resiliently) by the elastic spring element 46 or the elastic spring elements 46.
- Fig. 9B and Fig. 9C move counter to the axial direction A, whereby the elastic spring element 46 or the elastic spring elements 46 are compressed and whereby the guide screw(s) 38 screwed to the base plate 26 move with their guide section 40 or their guide sections 40 relative to or along the through-bore(s) 36 of the pressure plate 32 and the screw head section 42 or the screw head sections 42 come or come out of contact with the pressure plate 32 and thus move or move away from the pressure plate 32.
- Fig. 9B shows a state which is reached with a lighter shock or impact
- Fig. 9C shows a state which is reached with a stronger shock or impact.
- the trigger mechanism preferably comprises the plunger 6, the conical spiral springs 18, the pressure plate 32, the central elastic spring element 34, the guide screw 38, and the elastic spring element 46.
- the guide screw 38 and the elastic spring element 46 are not only part of the trigger mechanism but also part of an impact protection mechanism or impact protection device according to the disclosure.
- the medical product 1 enables a reliable indication of whether or not a battery unit 12 is accommodated in the housing 2. Even when the battery is discharged, the indicator device continues to indicate whether the battery unit 12 is accommodated in the housing 2.
- the additional provision of the viewing window 24 or the viewing window/light guide in combination with the fluorescent base plate 26 and the emission of light to the exterior of the medical product 1 enhances the signaling effect of the indicator element.
