Description

Patient position conversion device for nursing critical patients

Technical Field

The invention relates to the technical field of medical care equipment, in particular to a patient position conversion device for nursing critical patients.

Background

Body position conversion refers to a process of changing the posture and position of a human body in a certain way. The posture is changed at regular time according to the needs of treatment, nursing and rehabilitation clinically, and the device has important significance for promoting the blood circulation of the whole body, preventing the occurrence of complications such as pressure sore, urinary tract infection, dropsy pneumonia, muscular atrophy, joint deformation and the like at early stage and ensuring the realization of expected effects of rehabilitation treatment and rehabilitation nursing; at present, most of critically ill patients still use the common flat-plate type examining bed in hospitals, the patients are inconvenient in posture conversion, and the common flat-plate type examining bed is not ideal for the critically ill patients in terms of nursing of the patients by medical staff and treatment recovery of the patients.

In order to solve the problems, a Chinese patent (patent publication No. CN 210872619U) discloses a posture conversion auxiliary device for critical care, which comprises an auxiliary component and a sickbed, wherein the sickbed is installed above the auxiliary component, a support is installed at the edge of the sickbed, the bottom end of the support is grounded, the sickbed comprises a frame, a central crossbar, a fan plate and a skirt edge, the skirt edge is welded at the inner wall of the frame, the edge of the frame is fixedly connected with the support, the two ends of the central crossbar are fixedly connected with the frame, the side wall of the central crossbar is movably connected with the fan plate through a hinge, the edge of the fan plate is in contact with the skirt edge, the bottom surface of the fan plate is in contact with the auxiliary component, the auxiliary component comprises a support column, a square seat, a sleeve, a rotary knob, a shaft seat, a threaded column, a first top block, a second top block and a transverse plate, the edge of the transverse plate is fixedly connected with the support seat through a welded mode, the top end of the square seat is fixed with a sleeve, a threaded hole is formed in the side wall of the sleeve, the sleeve is movably connected with the threaded column, one end of the threaded column is in contact with the first top block, the second top surface of the second top block, and the sleeve is connected with the inner side wall of the support column, and the top surface of the sleeve is connected with the top surface of the second top surface of the sleeve.

According to the scheme, the auxiliary assembly is utilized to rotate the auxiliary fan plate for a certain angle, so that the body position of the patient is converted; however, when the device rotates the scattering plate to change the body position of the patient, the whole body of the patient rotates a certain angle along with the scattering plate, so that the risk that the patient accidentally slides down the scattering plate exists, secondary injury is brought to the patient, and therefore the split body position changing device for changing the body position of the critically ill patient is needed.

Disclosure of Invention

The invention aims to provide a patient position conversion device for nursing critically ill patients, and aims to solve the problem that a patient of the prior art position conversion device is prone to accidentally sliding down a position rotating plate to cause secondary injury to the patient.

In order to achieve the above purpose, the invention provides the following technical scheme:

the basic technical scheme provided by the invention is as follows: the utility model provides a critical patient nurses with patient position conversion equipment, includes bed body, supporting seat, health rotation portion, head supporting part and shank rotation portion, supporting seat fixed connection be in the downside of bed body, health rotation portion includes health rotor plate, drive box, rotating wheel, regulation pole and bracing piece, the health rotor plate with the front side of bed body rotates and connects, the inboard rotation of drive box is connected with drive bevel gear and driven bevel gear, drive bevel gear with driven bevel gear meshes, the first rotation handle of drive bevel gear fixedly connected with, driven bevel gear with the concentric fixed connection of rotor plate, the rotor plate with first rotation handle all locates the outside of drive box, the rotating wheel with the one end eccentric rotation of adjusting the pole is connected, the other end of adjusting the pole with the downside of health rotor plate rotates and connects, the one end of bracing piece with the health rotor plate is articulated, the other end rotation of bracing piece is connected with the slider, the slider with bracing piece sliding connection, health rotation portion with shank rotation portion all has two, two the health rotation portion and two shank rotation portion all about the middle part of shank body the symmetry of bed body with the front side connection of bed body, the bed body connects the head supporting part with the front side of bed body.
