Description

An intelligent patient transfer vehicle

technical field

The invention relates to a device for stably transferring a patient on a sickbed, in particular to an intelligent patient transfer vehicle.

Background technique

Some patients in the hospital cannot move their limbs too much when the bed is transferred. At present, as far as the level of medical machinery in the hospital is concerned, patients can only rely on the manual transfer of their family members or medical staff when transferring the hospital bed. This not only increases the workload of medical staff. workload, and it is easy to cause bending of the patient's body at the same time, which may cause secondary injury to the patient.

Contents of the invention

The object of the present invention is to provide an intelligent patient transfer vehicle, which is safe and convenient, intelligently controlled, and can transfer patients smoothly.

The object of the present invention is achieved through the following technical solutions:

A crank slider mechanism that separates the left side plate and the right side plate in a V shape; the worm gear mechanism includes a worm wheel, a worm, an internally threaded sleeve rod, and an externally threaded rod. The threaded sleeve rod is connected with the worm gear); the worm is connected with the stepping motor; a horizontal straight rod is arranged at the lower part of the bottom plate, and the two ends of the horizontal straight rod are connected with the worm through a direction-changing gear; the bottom of the internally threaded sleeve rod is provided with Self-locking universal wheels.

In the present invention, the crank linear mechanism includes a linear motor, a pinion, a large gear and a rocker, a linear guide rail on the bottom plate, the rocker is arranged at the bottom of the middle plate, and the rocker is connected to the linear motor through the large gear and the pinion .

The slider crank mechanism includes a left bull gear and a right bull gear, the left bull gear and the right bull gear are respectively connected with the left plate and the right plate; the left bull gear and the right bull gear mesh with each other and rotate in opposite directions.

The screw mechanism includes a linear guide rail, a threaded rod and a screw slider, the linear guide rail is arranged at both ends of the middle plate, and a cylindrical roller is arranged above the linear guide rail, and the bed support connected to the upper deck is arranged on the cylindrical roller; The screw slide block on the linear guide rail is sleeved on the threaded rod, and the threaded rod is connected with the traverse motor.

In the present invention, the joints of the left side plate and the right side plate are arranged in an arc shape that fits each other. The left side plate and the right side plate are connected to the cylindrical rollers through the bed body support, and the bed body support is arranged in a double arc form so that the left side plate and the right side plate are close to the middle layer plate.

The bed board is raised steadily through the worm gear mechanism. The combination of the screw structure and the double rocker mechanism enables the left side board and the right side board to move out smoothly and laterally. The crank slider mechanism makes the left side board and the right side board separate in a V shape. Finally, the middle plate is shifted longitudinally through the linear mechanism of the crank slider.

Manually control the rising translation, automatic recovery, and return to the original position. The information on the display is updated synchronously with the information on the front desk computer of the hospital. A fingerprint reader is installed next to the display screen, and patients can confirm their identity through fingerprints.

The beneficial effect of the invention is that the patient can be transferred automatically and stably, which is convenient and quick, reduces the workload of the medical staff, and reduces the risk of moving the patient's transfer bed at the same time.

The worm gear mechanism includes a worm wheel 51, a worm 52, an internally threaded sleeve rod 18, and an externally threaded rod 4. Connection; the lower part of the bottom plate is provided with a horizontal straight rod, and the two ends of the horizontal straight rod are connected with the worm through the direction changing gear 3; the bottom of the inner thread sleeve rod is provided with a self-locking universal wheel 6.

Crank linear mechanism comprises linear motor 7, pinion 8, bull gear 9 and rocking bar 10, and the linear guide rail on the bottom plate, and thin bar is arranged on the middle plate bottom, and rocking bar is connected with linear motor by bull gear, pinion.

Slider crank mechanism comprises left bull gear 26, right bull gear 21, and left bull gear and right bull gear are connected with left side plate and right side plate respectively;

The screw mechanism includes a linear guide 22, a threaded rod 23 and a screw slide 36. The linear guide is arranged at both ends of the middle plate, and a cylindrical roller 17 is arranged above the linear guide. The bed support 24 connected with the upper plate is arranged on the cylindrical roller. On; the screw slider set on the linear guide rail is set on the threaded rod, and the threaded rod is connected with the traverse motor 15.

In order to realize the transfer of the intelligent patient transfer cart, the device also includes self-locking universal wheels, which are placed under the inner thread sleeve rod.

In order to ensure that the intelligent patient transfer vehicle can be suitable for more common medical beds, the beds can move freely up, down, left, and right in the space. In order to ensure that the patient is safer and faster during the transfer process, the patient transfer cart is set to be manually raised and moved, and automatically recovered to return to its original position.

The patient transfer cart consists of three layers of wooden boards. Firstly, the stepper motor 1 is connected to the pulley belt strip 2. Driven by the pulley, the worm rod 52 is driven to rotate. At this time, the direction-changing gear is connected to the worm rod to convert the lateral motion into a longitudinal motion. At the same time, the two ends of the worm are provided with threads, and the worm and the externally threaded rod are fixed. The externally threaded rod 4 moves up and down in the internally threaded sleeve 18 through the device of the worm gear and worm. Both ends above the middle plate 12 are equipped with fixed rails 16, the left side plate 131 and the right side plate 132 are fixed on the track 16 by rollers 17, the inside of the track is provided with a screw linear mechanism, and the screw rod is fixed above the middle plate by a bracket , the screw slider on the screw mandrel is fixed to the guide rail, and the screw mandrel is connected with the motor 15 through the shaft coupling 28 at the same time, and the motor keeps synchronous movement in the tracks at both ends, and the left side plate 131 and the right side plate 132 are horizontally Sent out, when the left side plate 131 and the right side plate 132 move to a certain position, the screw stops moving, and the left side plate 131 and the right side plate 132 are driven by the motor to rotate the disc 32 within a certain range, and the upper plate is smoothly moved. 13 sent to the designated position, the left side plate 131, the lower end of the right side plate 132 is equipped with a miniature linear mechanism, the left side plate 131 and the right side plate 132 are connected with the left big gear and the right big gear through the straight rod 33 and the miniature linear slider 34 Under the drive of motor 35, the right large gear rotates, and the left large gear meshes with the right large gear, so it rotates in the opposite direction. The side plate 132 is opened in a V shape, so that the patient’s head slowly falls from one end, and then the middle plate moves longitudinally under the push of the crank linear mechanism, so that the patient falls completely and safely, and then the worm gear makes the bed continue to rise to a certain height Driven by the motor, the left side plate 131 and the right side plate 132 are restored to close, and driven by the double rocker mechanism and the screw rod, the left side plate 131 and the right side plate 132 return to the top of the middle plate, Then, under the action of the crank linear mechanism, the middle plate is returned to directly above the bottom plate, and finally the bottom plate returns to the original height driven by the stepping motor 1, and the motion ends.
