The invention provides an intelligent nursing bed. The intelligent nursing bed comprises a bed body and a central control module, wherein a pressure sore prevention mattress assembly and a turnover air bag assembly are arranged on the bed body, and the pressure sore prevention mattress assembly comprises four movable frames arranged on the bed body and hinged through hinges; pressure sore prevention air bag cushions are placed on the movable frames, the turnover air bag assembly is arranged between the four movable frames and the upper surface of the bed body, and the turnover air bag assembly comprises at least four positive turnover air bags, at least three left turnover air bags and at least three right turnover air bags; the central control module is arranged below one side wall of the bed body and controls the pressure sore prevention mattress assembly and the turnover air bag assembly to work. According to the intelligent nursing bed, nursing and rehabilitation related functions are integrated in the mattress, so that the external cost and the occupied space can be reduced; the intelligent mattress can reduce the labor intensity of nurses and improve experience of a patient.

A radial universal seal device for a trocar and a trocar comprising the radial universal seal device. The radial universal seal device comprises: a guiding and adjustment mechanism (1), a seal ring (3), a rotary mechanism (4), and a housing (2). The guiding and adjustment mechanism (1) is of a wasp waist-shaped funnel structure with a big upper end, a small middle part, and a big lower end. When a surgical instrument (9) is inserted, by taking the wasp waist of the wasp waist-shaped funnel structure as a fulcrum, and through concerted movement of a rotary shaft (101), a wasp waist adjustment fulcrum (104), an expanded edge (105), and a force bearing edge (32) of the seal ring (3), the guiding and adjustment mechanism (1) can automatically sense the size of the outer diameter of the surgical instrument (9), so as to adjust the diameter of a surgical instrument through hole (31) of the seal ring (3), thereby achieving the objective of automatically adapting to different inserted surgical instruments (9), and not only achieving the low motion resistance but also keeping desirable sealing performance.

The invention relates to a sickbed, in particular to a sickbed convenient for an internal medicine bedridden patient to overturn. The technical problem to be solved by the invention is to provide a sickbed convenient for an internal medicine bedridden patient to overturn, which can continuously overturn the patient instead of overturning the patient manually to reduce the labor cost and can also prevent the patient from being scratched. The invention adopts the technical scheme that the sickbed convenient for the internal medicine bedridden patient to overturn comprises a bed plate, a soft cushion, a movable plate, supporting legs, vertical plates, a cross rod, a sliding sleeve, a connecting rod, a first bearing pedestal, a lead screw, a first nut, a fixing block and the like; the supporting legs with supporting effects are symmetrically and fixedly connected with the left side and the right side at the bottom of the bed plate; the vertical plates are symmetrically and fixedly connected with the left side and the right side at the bottom of the bed plate. The sickbed convenient for the internal medicine bedridden patient to overturn, provided by the invention, has the beneficial effects that through starting the drive motor, the movable plate can swing upwards to overturn the patient without manually overturning the patient by medical staff, so that the labor cost is reduced, and an eye on the patient is not required to be kept; through a pushing device, the patient can be pushed to overturn, so that overturn is quicker.
