Abstract
Description
Title of the invention: Tortuous internal chassis of a medical ventilator
[0001] The invention relates to a medical ventilator provided with a tortuous internal medical ventilator frame, ventilator equipped with such a frame and method of additive manufacturing of the frame.
[0002] Medical assisted ventilation apparatus or devices, also called medical ventilators, may comprise an internal chassis forming a support structure for all or part of the elements making up the medical ventilator, in particular a turbine supplying the gas, one or more electronic cards, the internal fluid circuit(s), the external casing of the ventilator, and sometimes a support arm carrying a display screen... An example is given by EP4043776.
[0003] Usually, the internal frame is formed of plates or the like made of metal, for example aluminum alloy or steel, assembled together, for example by riveting, welding or the like.
[0004] This type of chassis structure poses a problem because it leads to a chassis that can be heavy depending on the number of plates constituting it, which can include sharp plate edges, thus risking injuring maintenance operators, whose different elements (i.e. plates or others) can be difficult to assemble if its architecture is complex.... There is therefore a need for an improved internal fan chassis, in particular one that is lighter, simpler to manufacture, and that does not generate or causes less risk of injury...
[0005] The solution of the invention relates to a frame for a medical ventilator comprising a rigid three-dimensional structure formed from several elements secured to each other, characterized in that the three-dimensional structure is formed from elements obtained by an additive manufacturing process.
[0006] Depending on the embodiment considered, the chassis of the invention may comprise one or more of the following characteristics: - the three-dimensional structure is made of polymer. - the elements form a tortuous three-dimensional structure. - at least part of the elements form a support arm surmounting the three-dimensional structure. Such a support arm is intended to carry a medical ventilator display screen. - the three-dimensional structure is formed from a single piece. - alternatively, the three-dimensional structure is formed of several sub-units or sub-parts assembled to one another or to each other.
[0007] The invention also relates to a medical ventilator comprising an internal chassis according to the invention.

[0018] Depending on the embodiment considered, the medical ventilator of the invention may comprise one or more of the following features: - it includes a gas-delivering turbine arranged on the chassis. - it includes means of control. - the control means include an electronic microprocessor card. - the chassis includes a supporting arm surmounting the three-dimensional structure. - the carrying arm carries a display screen. - it includes a gas circuit arranged on the chassis. - it includes an internal battery arranged on the chassis. The invention further relates to a method for manufacturing a frame for a medical ventilator according to the invention, characterized in that the three-dimensional rigid structure is produced by implementing an additive manufacturing method. Depending on the embodiment considered, the method of the invention may comprise one or more of the following characteristics: - the additive manufacturing process uses a wire or a powder. - the thread or powder includes a polymer. The invention will now be better understood thanks to the following detailed description, given for illustrative but non-limiting purposes, with reference to the appended figures among which: [Fig.l] diagrams an embodiment of a chassis for a medical ventilator according to the invention. [Fig.2] shows a diagram of the chassis of [Fig.l] equipped with different components of a medical ventilator. [Fig.l] schematizes an embodiment of a frame 1 for a medical ventilator comprising a rigid three-dimensional structure 2 formed of several elements 3 secured to each other. We see that the three-dimensional structure 2 is tortuous. The three-dimensional structure 2 is made of polymer. It is made up of elements of various shapes which have been obtained by additive manufacturing from polymer in the form of wire, powder or other. In other words, the three-dimensional structure assembly 2 was produced using an additive manufacturing process. Depending on the embodiment, it may be formed from a single part or, conversely, from several sub-parts assembled together. Here, the three-dimensional structure 2 comprises a part forming a support arm 4 surmounting the main body 5 of the three-dimensional structure 2. Such a support arm 4 is intended to carry the display screen of a medical ventilator.
[0019] Furthermore, the main body 5 of the three-dimensional structure 2 here comprises legs or feet 6 supporting the main body 5 of the three-dimensional structure 2. Here, the legs or feet 6 come to bear in the bottom 7 of a medical ventilator, that is to say on the wall closing the base of the external carcass of a medical ventilator (rest of the ventilator not shown).
[0020] [Fig.2] is analogous to [Fig.l]. It schematizes the chassis 1 carrying different components of the medical ventilator, namely here a turbine 8 delivering a medical gas, such as air, oxygen or an air / O2 mixture, a gas circuit 9 and an electronic card 10.
