Description

Medical transfer bed

Technical Field

The invention relates to the technical field of beds special for nursing A61G7/00, in particular to a medical transfer bed.

Background

When a critically ill patient or an elderly person is transferred from a ward to a clinic or an operating room, the patient needs to first move the other to a transfer bed. However, the procedure of transferring a critically ill patient or an elderly person from a hospital bed to a transfer bed is very laborious and is also prone to accidental injury.

Chinese patent document CN 204971962U discloses a nursing hospital bed, which aims to solve the technical problem that the existing nursing hospital bed is inconvenient for patient transfer, and comprises a bed frame, a bed board, a horizontal transfer mechanism, a lifting mechanism and a magnetic attraction alignment mechanism; the lifting mechanism is a lifting cylinder, the horizontal conveying mechanism comprises a driving motor, a lead screw and a nut, and the nut is connected with the bed plate. The scheme adopts a mode that two sickbeds share one bed board, and after the bed board with sicknesses is lifted up by the lifting mechanism, the bed board is integrally moved to the other sickbed by the horizontal conveying mechanism. But the actual situation in a hospital is: the sickbed is spacious for the comfort of the patient, and the transfer bed is narrow because the sickbed needs to shuttle in the corridor, so that the sickbed is not beneficial to shuttle in the corridor if the sickbed plate of the sickbed is placed on the transfer bed. Therefore, the scheme is actually not beneficial to practical popularization and application.

Chinese patent document CN 109646196 a discloses a multifunctional nursing bed, which comprises a transfer bed, a bed head structure and a storage box, wherein the transfer bed is composed of a bed plate, a push handle, a handrail device and a hydraulic lifting platform. The board bodies hinged and assembled with each other are adopted to form the containing box and serve as the other half of the sickbed, so that the area of the sickbed is increased, and the transfer trolley is suitable for long-term bed lying conditions. This scheme needs the manpower to move the disease to the one side at transportation bed place when in actual use, and the original pad quilt of laying on the disease bed also can't be handled properly moreover, does not actually do not also benefit to reality and popularize and apply.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a medical transfer bed which can conveniently transfer a patient to the transfer bed.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a medical transfer bed comprises a bed frame, a bed board, a lifting mechanism and a horizontal conveying mechanism, wherein the lifting mechanism is used for vertical movement of the bed board, the horizontal conveying mechanism is used for horizontal movement of the bed board, the bed board is in an insertion piece shape so as to be convenient for the horizontal conveying mechanism to place the bed board under the body of a patient, and a limiting cushion layer is fixed on the upper surface of the bed board.

As an improvement, the limiting cushion layer comprises an air cushion layer.

As a further improvement, the air cushion layer is provided with an air pump; after the air pump is inflated, the air cushion layer is in a state that two sides are higher than the middle.

As a still further improvement, the limiting cushion layer comprises a water cushion layer, and the water cushion layer is located on the upper surface of the air cushion layer.

As an improvement, the lifting mechanism comprises a lifting platform, a hydraulic cylinder and a pedal.

As an improvement, the horizontal conveying mechanism comprises a ball screw, a motor for driving the ball screw to rotate and a sliding block driven by the ball screw, and the bed plate is fixed with the sliding block.

As a further improvement, the ball screw is provided with a hand wheel.

As a further improvement, the horizontal conveying mechanism comprises a light bar for guiding the sliding block.

As a still further improvement, the horizontal transfer mechanism includes a limit switch that defines a limit of movement of the slider.

The invention has the following inventive concept: the medical transfer bed is not structurally related to the conventional sickbed, so that the function of transferring the patient to the medical transfer bed after the patient is lifted from the sickbed can be realized by the single medical transfer bed. Because the bed board of medical transfer bed is narrow relatively, set up spacing bed course on the upper surface of bed board, avoid the disease to follow unexpected landing on the bed board. The medical transfer bed can be lowered at ordinary times and then placed at the bottom of a sickbed, and accompanying personnel can be taken out for use at night. Horizontal transport mechanism, air cushion layer, water bed course three cooperation are used, can make medical transfer bed have better massage function, bed disease is long bedsore easily for a long time, can regularly shift bed disease to medical transfer bed to make horizontal transport mechanism remove about, then the water bed course can produce better massage effect to patient, the air cushion layer is that both sides are higher than the state in the middle and can prevent that the disease from dropping, and produce certain extrusion massage effect to the side of disease.

In conclusion, the invention has the advantages of novel structure and convenient use, can conveniently transfer patients to the transfer bed and also has the massage and health care functions.

Detailed Description

Example 1

As shown in fig. 1-2, the medical transfer bed of the present invention comprises a bed frame 1, a bed plate 2, a lifting mechanism 3, and a horizontal transfer mechanism 4, wherein the lifting mechanism 3 is used for vertically moving the bed plate 2, and the horizontal transfer mechanism 4 is used for horizontally moving the bed plate 2. A limit cushion layer 21 is fixed on the upper surface of the bed plate 2.

The lifting mechanism 3 is driven by manpower and comprises a lifting platform 31, a hydraulic cylinder 32 and a pedal 33. The product is an existing product and can be purchased. In this example, a product PT150Z manufactured by ningbo jie li logistics equipment ltd was used.

The horizontal transfer mechanism 4 includes a ball screw 41, a motor 42 that drives the ball screw 41 to rotate, and a slider 43 driven by the ball screw 41. The slide block 43 is provided with a convex block 47, the bottom of the bed plate 2 is provided with a concave block 22, and the convex block 47 is sleeved with the concave block 22 to fix the bed plate 2 and the slide block 43. Two sides of the ball screw 41 are respectively provided with a light bar 45, and the light bars 45 play a guiding role for the slide block 43, so that the position deviation of the bed plate 2 in the translation process is avoided. The horizontal transfer mechanism 4 includes a limit switch 46 that defines the limit of movement of the slider 43. The limit switch 46 has an independent opening mechanism, and is mainly used during the health care massage, so that the bed board 2 can move left and right back and forth, and the effect of massaging the back and two sides of the patient is realized.

The ball screw 41 is provided with a hand wheel 44 to facilitate manual operation in case of power failure.

As shown in fig. 3 to 4, the limiting cushion layer 21 includes an air cushion layer 211 and a water cushion layer 213, and the water cushion layer 213 is located on the upper surface of the air cushion layer 211. An air nozzle 214 is arranged on the side surface of the air cushion layer 211, the air cushion layer 211 is provided with an air pump 212, the air pump 212 is fixed on the bedstead 1, and an air pipe is connected between the air pump 212 and the air nozzle 214, and the air pipe is not shown in the figures in the specification; after the air pump 212 is inflated, the air cushion layer 211 is in a state that both sides are higher than the middle.

When the medical transfer bed is used, the medical transfer bed is moved to one side of the sickbed 6, the lifting mechanism 3 is lifted, and the bed plate 2 is slightly higher than the bedding of the sickbed 6. Then the horizontal transmission mechanism 4 is started, and the bed board 2 is in a plug-in shape and can be inserted under the body of a patient. Then, the air pump 212 is started, and the air cushion layer 211 is inflated to be in a state that two sides are higher than the middle, so that two sides of the patient are wrapped. Subsequently, the bed plate 2 is retracted to the bed frame 1 by the reverse driving of the ball screw 41.
