DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.

Embodiment 1

As shown in Figures 1, 2 and 3, an embodiment of the present invention discloses a patient transfer bed including a bed board 1, a bed board support frame 2 and a quick-detachable component 3. The bed board 1 is a rectangular board, which is used for patients to lie down and rest, and is also used to keep patients in a lying position after surgery; the bed board support frame 2 is formed by splicing a plurality of cross bars and a plurality of longitudinal bars. The bed board 1 is arranged on the top of the bed board support frame 2, and the weight of the bed board 1 and the patient is supported by the bed board support frame 2. The bottom of the bed board support frame 2 can be provided with rubber anti-slip, and can also be provided with universal casters with locking function, so as to facilitate the movement of the bed and the patient. It should be noted that the bed board 1 and the bed board support frame 2 can also be formed by splicing rods or plates, or can be an integral structure, which can be selected according to actual needs.

Furthermore, the quick-detachable component 3 of this embodiment includes a rotating mechanism 31 and a clamping mechanism 32. The rotating mechanism 31 is used to control the rotation of the bed board 1 relative to the bed board support frame 2, and the clamping mechanism 32 is used for the fixed connection and separation of the bed board 1 and the bed board support frame 2. Specifically, the rotating mechanism 31 includes a rotating shaft 311 and a rotating drum 312. In this embodiment, the bottom of the rotating drum 312 is fixed by a bottom plate, and then the bottom plate is connected and arranged between two cross bars of the bed board support frame 2. When the bed board support frame 2 is an integral structure, it is necessary to open a receiving space in the middle of the bed board support frame 2 to place the rotating mechanism 31. The rotating shaft 311 is coaxially rotatably arranged in the rotating drum 312, that is, the rotating shaft 311 is inserted in the rotating drum 312 and can rotate, and the rotating shaft 311 is perpendicular to the bed board 1. The circumferential surface of the rotating shaft 311 is in contact with the inner circumferential surface of the rotating drum 312, thereby preventing the rotating shaft 311 from shaking in the rotating drum 312.

Furthermore, the clamping mechanism 32 includes a first clamping plate 321, a second clamping plate 322, an elastic component 323 and a sliding connection plate 324; in this embodiment, the first clamping plate 321 and the second clamping plate 322 can be rotatably set on a fixed plate, and the fixed plate is set on the end surface of the rotating shaft 311 facing the bed board 1. It should be noted that when the end surface of the rotating shaft 311 facing the bed board 1 can completely cover the sliding connection plate 324, the end surface of the rotating shaft 311 facing the bed board 1 can be directly regarded as a fixed plate, that is, the first clamping plate 321 and the second clamping plate 322 are directly rotatably set on the end surface of the rotating shaft 311 facing the bed board 1. In this embodiment, the first clamping plate 321 and the second clamping plate 322 are both rotatably set on the end surface of the rotating shaft 311 facing the bed board 1 through a pin, and the rotation center of the first clamping plate 321 and the rotation center of the second clamping plate 322 are arranged at equal angles around the axis of the rotating drum 312. The pin is also arranged at a position relative to the center of the first clamping plate 321 and the second clamping plate 322. Of course, in addition to the pin, a bearing, a screw or a hinge or other components capable of realizing rotational cooperation can also be used to connect the clamping plate and the fixed plate.

The sliding connection plate 324 of this embodiment is fixedly arranged on the bed board 1, and the sliding connection plate 324 can slide between the first clamping plate 321 and the second clamping plate 322. It is worth noting that when the sliding connection plate 324 is arranged between the first clamping plate 321 and the second clamping plate 322, the end faces opposite to each other between the first clamping plate 321 and the second clamping plate 322 fit with the end faces of the two side faces of the sliding connection plate 324. For example, in this embodiment, the two side faces of the sliding connection plate 324 are parallel planes, and the end faces opposite to each other between the first clamping plate 321 and the second clamping plate 322 are also parallel planes. Of course, according to actual needs, they can be set to be inclined planes or wavy planes to match each other. The elastic component 323 is connected between the first clamping plate 321 and the second clamping plate 322. When the sliding connecting plate 324 is not between the first clamping plate 321 and the second clamping plate 322, the elastic component 323 remains in its original state, and its original length is smaller than the distance between the first clamping plate 321 and the second clamping plate 322. Therefore, the first clamping plate 321 and the second clamping plate 322 rotate around the pin to shorten the distance between the connection points, so that the connection points are close to each other to adapt to the length of the elastic component 323, and the other side of the first clamping plate 321 and the second clamping plate 322 opposite to the connection point is One side is far away from each other, and the spacing between the sides far away from each other is greater than the width of the sliding connecting plate 324. Therefore, when installing the bed board 1, it is convenient for the sliding connecting plate 324 to slide smoothly between the first clamping plate 321 and the second clamping plate 322. After the sliding connecting plate 324 slides in, the connection between the first clamping plate 321 and the second clamping plate 322 is stretched open by the sliding connecting plate 324, and the elastic component 323 is stretched to have elastic force. The first clamping plate 321 and the second clamping plate 322 clamp the sliding connecting plate 324 under the action of the elastic restoring force of the elastic component 323.

It should be noted that the elastic component 323 of the present embodiment is a spring. Of course, according to actual needs, a leaf spring or other components that can provide elastic restoring force may also be used.

Combined with FIG. 4 , the specific method of using the patient transfer bed of this embodiment is that when it is not necessary to transfer a patient, the bed board 1 is fixed by the bed board support frame 2 for the patient to lie down and rest. When it is necessary to transfer a patient, prepare another empty patient transfer bed for use, first rotate the bed board 1 to drive the sliding connection plate 324 to rotate, and the sliding connection plate 324 is clamped between the first clamping plate 321 and the second clamping plate 322, thereby driving the first clamping plate 321 and the second clamping plate 322 to rotate, and further drive the rotating shaft 311 to rotate on the rotating drum 312 through the connecting plate, when the bed board 1 rotates a certain angle, pushing the bed board 1 can drive the sliding connection plate 324 to move out from between the first clamping plate 321 and the second clamping plate 322, and put the removed bed board 1 aside. Continue the previous operation, rotate the bed board 1 of the bed where the patient lies to be vertically interlaced with the bed board support frame 2, then push the bed board 1 where the patient lies, and slide it onto the bed board support frame 2 of another bed. The bed board 1 is always kept horizontal under the support of the two bed board support frames 2, and the sliding connecting plate 324 under the bed board 1 where the patient lies can be inserted between the first clamping plate 321 and the second clamping plate 322 of another empty bed and clamped, and the bed board 1 where the patient lies can be rotated back to complete the transfer of the patient. During the transfer process, the patient always maintains the original posture, is not affected by external forces, and will not feel uncomfortable. The entire transfer process is stable, fast and reliable. Finally, slide the bed board 1 placed on one side onto the bed board support frame 2 of the bed where the patient originally lay, so that the bed can be used by a new patient.

It is worth noting that in this embodiment, since the bed board 1 is always mounted on the bed board support frame 2, the sliding connecting plate 324 will interfere with the bed board support frame 2 during movement, so a retreat groove 21 will be opened on the side of the bed board support frame 2 for the sliding connecting plate 324 to pass through.

Embodiment 2

As another embodiment of the present invention, different from the previous embodiment, the patient transfer bed of this embodiment further includes a locking mechanism 4, which includes a locking plate 41 and a locking screw 42. A first threaded hole is provided on the locking plate 41, one end of the locking plate 41 is hinged to the bed board support frame 2, one end of the locking screw 42 is screwed to the first threaded hole, and a second threaded hole is provided at the end of the bed board 1, and the other end of the locking screw 42 is screwed to the second threaded hole. In this embodiment, four locking mechanisms 4 are provided, two are provided at one end of the bed board support frame 2 in the length direction, and the other two are provided at the other end of the bed board support frame 2 in the length direction. When it is not necessary to transfer a patient, by tightening the locking screws 42 on both sides of the bed board 1, the locking plate 41 restricts the bed board 1 from rotating. When it is necessary to transfer a patient, the locking screw 42 is released to separate the locking screw 42 from the bed board 1, and the locking plate 41 rotates downward around the hinge point, thereby not interfering with the rotation of the bed board 1. The articulated connection can be a hinge or a hinge.

Embodiment 3

Combined with Figure 5, as another embodiment of the present invention, different from the previous embodiment, the rotating drum 312 of this embodiment includes a drum bottom 3121 and two guide blocks, the guide blocks include an inclined slide 3122, a plane slide 3123 and a limit block 3124 connected in sequence, the rotating shaft 311 includes an axle body 3111 and two sliders 3112, wherein the inclined slide 3122 and the plane slide 3123 both slide relative to the slider 3112 to realize the function of raising the bed board 1, thereby avoiding the sliding connecting plate 324 from interfering with the bed board support frame 2 during movement. Therefore, in this embodiment, there is no need to set a retreat groove 21 for the sliding connecting plate 324 to pass through, thereby ensuring the structural strength of the long version support frame.

Furthermore, the two guide blocks of this embodiment are arranged at equal angles around the axis of the rotating cylinder 312 and at the end surface of the cylinder bottom 3121 facing the rotating shaft 311, that is, the two guide blocks are symmetrical about the axis center of the rotating cylinder 312. One end of the inclined slideway 3122 is smoothly connected to the end surface of the cylinder bottom 3121 facing the rotating shaft 311, and the other end of the inclined slideway 3122 is smoothly connected to the plane slideway 3123. The two sliders 3112 are arranged at equal angles around the axis of the rotating shaft 311 and at the end of the rotating shaft 311 facing the cylinder bottom 3121, that is, the two sliders 3112 are symmetrical about the axis center of the rotating shaft 311. The two sliders 3112 are arranged one by one with the two guide blocks, and the sliders 3112 abut against the end surface of the cylinder bottom 3121 facing the rotating shaft 311. The sliders 3112 can be rotated around the rotation center and can be slid on the inclined slideway 3122 and the plane slideway 3123. When the bed board 1 is rotated, the rotating shaft 311 can be driven to rotate, thereby driving the slider 3112 to first slowly rise along the inclined slide 3122, and finally rotate horizontally on the plane slide 3123. The height of the plane slide 3123 is the height of the rising of the bed board 1, thereby avoiding interference between the sliding connecting plate 324 and the bed board support frame 2 during the movement of the bed board 1.

The two limit blocks 3124 are respectively arranged on the side of the plane slide 3123 away from the inclined slide 3122 connected thereto. The height of the limit block 3124 exceeds the plane slide 3123. When the bed board 1 rotates a certain angle, the side of the slider 3112 can be operable to abut against the side of the limit block 3124, thereby limiting the further rotation of the bed board 1 and facilitating the movement of the bed board 1.

Embodiment 4

As another embodiment of the present invention, different from the previous embodiment, the first clamping plate 321 and the second clamping plate 322 of this embodiment are both provided with protrusions on the opposite end surfaces, and the elastic component 323 connects the protrusions on the first clamping plate 321 and the protrusions on the second clamping plate 322; the two side surfaces of the sliding connecting plate 324 are respectively abutted against the opposite end surfaces of the first clamping plate 321 and the second clamping plate 322, and one end of the sliding connecting plate 324 abuts against the two protrusions. That is to say, after the sliding connecting plate 324 slides into the first clamping plate 321 and the second clamping plate 322, it will abut against the protrusions after sliding into a certain distance, thereby stopping further sliding, and also preventing the sliding connecting plate 324 from continuing to slide and damaging the elastic component 323.

Furthermore, flanges are provided on both side surfaces of the sliding connecting plate 324, and sliding grooves are provided on the opposite end surfaces of the first clamping plate 321 and the second clamping plate 322. The two flanges are slidably arranged in the two sliding grooves, which not only play a guiding role, but also limit the sliding connecting plate 324 from detaching upward from the clamping block, thereby ensuring that the sliding process is always smooth.

The above is a description of a specific embodiment of the present specification. Other embodiments are within the scope of the appended claims. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be regarded as the scope of protection of this application.
