Description

Combined mattress for vital sign monitoring Technical Field The invention relates to the technical field of mattresses, in particular to a combined mattress for vital sign monitoring. Background The vital sign is a core index reflecting the health condition of a human body, the real-time monitoring of the vital sign has important significance in the fields of medical care, home health management, senior service and the like, the traditional vital sign monitoring mode mainly depends on contact type monitoring equipment, such as electrocardiographs, sphygmomanometers, oximeters and the like, the equipment is usually required to be in direct contact with the human body and operated by professionals, the wearing comfort level is poor, the constraint feeling is easily caused to the user, the long-time continuous monitoring is difficult to realize, and the device is especially not suitable for daily monitoring scenes of sleep states, old people or mobility inconveniences. In order to solve the above problems, various mattress products for vital sign monitoring have appeared in the prior art, and the core principle is that sensing elements (such as pressure sensors, optical fiber sensors, piezoelectric sensors, etc.) are embedded in the mattress, and the collection and analysis of vital sign parameters are realized by sensing micro vibrations generated by human breath and heartbeat, etc. However, existing monitoring mattresses still suffer from a number of technical drawbacks: The existing product has fixed supporting hardness, cannot meet the requirements of different scenes, not only is difficult to reduce the pressure sore risk of a long-term bedridden patient through the soft support of the self-adaptive fit human body curve, but also cannot provide a strong bearing and high-stability hard supporting plane required by emergency measures or body position adjustment, and is limited in applicable scene; The support elasticity of the traditional mattress is fixed, the sinking degree can not be adjusted according to the body type of a patient, the posture of a bedridden patient or the rehabilitation requirement, the comfort is influenced by the excessively hard support, or the support safety is lacked due to the excessively large sinking, so that the user experience and the clinical use requirement are difficult to balance; therefore, the existing monitoring mattress has the technical problems that the supporting hardness of the product is fixed, different scene requirements cannot be considered, the supporting elasticity is fixed, and the user experience and the clinical use requirements are difficult to balance. Disclosure of Invention Therefore, the invention provides a combined mattress for vital sign monitoring, which effectively solves the technical problems that the supporting hardness of a monitored mattress product is fixed, different scene requirements cannot be considered, the supporting elasticity is fixed, and the user experience and the clinical use requirement are difficult to balance in the prior art. In order to solve the technical problems, the invention particularly provides a combined mattress for vital sign monitoring, which comprises the following technical scheme: a top mattress body in which a first inner cavity is formed to be opened upwards; The bottom mattress body is assembled with the top mattress body into a whole, and a second inner cavity which is opened upwards is formed in the bottom mattress body; the cushion cover is arranged at the top of the top mattress body and covers the first inner cavity; the limiting unit is arranged in the first inner cavity and is right opposite to the bottom of the cushion cover; The hard supporting unit is arranged in the first inner cavity and is right opposite to the bottom of the cushion cover; The soft supporting unit is arranged in the first inner cavity and is right opposite to the bottom of the cushion cover; The assembly component is arranged on the bottom mattress body, and the bottom mattress body is assembled and connected with the top mattress body through the assembly component; The first lifting unit is arranged in the second inner cavity and is opposite to the limiting unit; The second lifting unit is arranged in the second inner cavity and is opposite to the soft supporting unit; a non-contact monitoring element mounted on the base mattress body; The cushion cover comprises a cushion cover, a cushion unit, a limiting unit, a hard support unit, a soft support unit and a soft support unit, wherein the limiting unit, the hard support unit and the soft support unit form a cushion module, a plurality of cushion modules are closely arranged in the first inner cavity in an array, and at least one of the limiting unit, the hard support unit and the soft support unit is in contact with the cushion cover and supports the cushion cover in one cushion module; Under the assembled state of the top mattress body and the bottom mattress body, connecti
