[0002] With the rapid growth of the medical population in hospitals, the number of critically ill patients who need to be moved and transported in the emergency or hospitalization department of the hospital is also increasing. These emergency patients who need emergency treatment generally have an acute onset and are in critical condition.

DETAILED DESCRIPTION

[0043] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0044] Example

[0045] like Figure 1-7 As shown, this embodiment provides a transfer bed for an imaging room, comprising a base 000, a lifting base 100, a mounting frame 200, a first bearing part 300, a second bearing part 400 and a third bearing part 500, wherein the lifting base 100 is connected with the mounting frame 200, and the mounting frame 200 is used to mount structural parts such as the first bearing part 300, the second bearing part 400 and the third bearing part 500;

[0046] The mounting frame 200 has mounting platforms 201 at both ends thereof, wherein the mounting platforms 202 are used to mount the first bearing part 300 and the second bearing part 400 respectively;

[0047] Specifically, the first bearing part 300 and the second bearing part 400 are arranged correspondingly, such as the first bearing part 300 is basically symmetrically arranged with the second bearing part 400, and the structures are similar, wherein:

[0048] The first bearing part 300 and the second bearing part 400 are both mounted on the mounting platform 202 through the slide grooves at the bottom thereof. In this embodiment, the first bearing part 300 and the second bearing part 400 are both mounted on the slide rail 2021 of the mounting platform 202 through the slide grooves at the bottom thereof, so that the first bearing part 300 and the second bearing part 400 can slide on the mounting platform 202. Specifically, they are driven by the corresponding first driving mechanism 203 on the mounting platform 202 to realize forward and backward movement.

[0049] That is, the first carrying part 300 and the second carrying part 400 are respectively connected to the first driving mechanism 203 disposed in the mounting platform 202;

[0050] In order to realize that the first bearing part 300 and the second bearing part 400 drive the corresponding first bed board 301 and the second bed board 401 to move forward and backward, the first bearing part 300 and the second bearing part 400 are both installed with a second driving mechanism 207, and are connected to the first bed board 301 and the second bed board 302 through the second driving mechanism 207 connected thereto. Preferably, the end of the second driving mechanism 207 is a connecting member 2071, which is used to connect the first bed board 301 or the second bed board 401. The connecting member 2071 is rotatably installed on the second driving mechanism 207, so that it can not only drive the first bed board 301 or the second bed board 401 to translate, but also drive the first bed board 301 or the second bed board 401 to tilt when the second driving mechanism 207 is raised, and accordingly, it can also drive the third bed board 501 to tilt;

[0051] In order to cooperate with the tilting, in this embodiment, the first bearing part 300 and the second bearing part 400 are both provided with a mounting frame 204 for connecting the corresponding first driving mechanism 203, so as to facilitate the first driving mechanism 203 to drive the movement; wherein, a rotatable shaft 2051 is also installed in the mounting frame 204, and both ends of the shaft 2051 are provided with a movable mounting frame 205, and the movable mounting frame 205 is used to install the corresponding first bearing part 300 or the second bearing part 400, so as to realize the aforementioned when the second driving mechanism 207 is raised, it can also drive the first bed board 301 or the second bed board 401 to achieve tilting, and accordingly, it can also achieve the tilting of the third bed board 501;

[0052] The first bearing part 300 and the second bearing part 400 both have a sub-plate 208 connected thereto, wherein the two sub-plates 208 are respectively connected to the corresponding third bearing parts 500 , and the third bearing parts 500 have a third bed board 501 mounted thereon.

[0053] In order to realize independent movement with the third bed board 501, the first bed board 301 and the second bed board 401 are both provided with step portions 212, which facilitates the protruding parts at both ends of the third bed board 501 to move on the step portions 212, and also maintains the flatness of the entire bed surface; as a preferred embodiment, Figure 8 , 9 As shown in Figure 10, the protruding portion of the third bed board 501 can also be set as an extension portion 504, which is significantly lengthened to accommodate the head and feet of the patient. Accordingly, the step portion 212 is also configured to be a size suitable for the extension portion 504. In this embodiment, the patient can be completely located on the third bed board 504.

[0054] Preferably, the first bed board 301, the second bed board 401 and the third bed board 501 are made of wood composite board, plastic board or the like.

[0055] Specifically, regarding the sub-plate 208, the sub-plate 208 has a groove 2081, wherein the third bearing part 500 has an auxiliary track 502 corresponding thereto, which is used for the third bearing part 500 to slide. When the auxiliary tracks 502 on the sides of the two third bearing parts 500 are installed in the groove 2081, the function of sliding the third bearing part 500 back and forth is realized. The sub-plate 208 has a third driving mechanism 209, which is installed in the sub-plate 208, and the third driving mechanism 209 is connected to the third bearing part 500 through the third bearing part connecting member 503. In this way, when the first driving mechanism 203 moves, the two third bearing parts 500 are synchronously driven to move back and forth. Since the third bed board 501 is installed on the two third bearing parts 500, the third bed board 501 can move back and forth synchronously with the first bed board 301 and the second bed board 401. As for the third driving mechanism 209, since it is connected to the third bearing part connecting member 503 of the third bearing part 500, it can drive the third bearing part 500 to move forward and backward independently;

[0056] Specifically, as a preferred embodiment, at least two crossbeams 201 are provided on the mounting frame 200, wherein each crossbeam 201 is provided with at least one sliding portion 2011 to support the third bed board 501, making the sliding more stable and safe.

[0057] The first carrying portion 300 and the second carrying portion 400 both have a second mounting frame 206 for mounting a second driving mechanism 207 .

[0058] A group of connection structures are respectively arranged on both sides of the bottom of the installation frame 200, each of which has two connection seats 210 for installing the guardrail 211, so as to realize the storage and support of the guardrail 211, so as to prevent the patient who cannot control himself from falling, etc.;

[0059] In this embodiment, the first drive mechanism 203, the second drive mechanism 207 and the third drive mechanism 209 include an electro-hydraulic push rod, and other drive components can also be selected; the typical implementation method realizes the working load requirement of more than 200kg. Considering factors such as the deadweight of the bed, the thrust of the electro-hydraulic push rod should be selected to be more than 300kg (3000N). Stroke selection: According to the standard of YY0570-2013, the lifting stroke is ≥200mm. In addition, considering the angle or stroke requirements of other actions, the stroke of the push rod is ≥500mm, and the speed of movement is preferably 20-40mm / s. 3. Voltage / current: Considering the use environment of the transfer bed and the opportunity of contact with the human body, direct current is generally suitable, either 12v or 24v. In the design of the transfer bed, we choose to use an electro-hydraulic push rod as the drive and transmission device of the transfer bed. The advantages of the hydraulic system are: small size and light weight, so the inertia force is small, and when an unexpected situation occurs during the transfer, resulting in sudden overload or parking, no large impact will occur. Secondly, because oil is used as the working medium, the relative moving surfaces of the components can be self-lubricated, with less wear and long service life. At the same time, the transfer bed is easy to operate and control, with a high degree of automation. The overload protection is sensitive, stable and reliable. The control system receives the design parameters of the single-chip microcomputer through the serial port and parses them into corresponding action commands. Through the sensor, hydraulic valve drive circuit, and electro-hydraulic push rod drive circuit, the hydraulic cylinder and electro-hydraulic push rod complete the specified movement. The lifting angle of the transfer bed is measured by the infrared sensor, and the feedback is fed back to the single-chip microcomputer to correct the actual height of the bed. In the design of the control of the electro-hydraulic push rod, we use the BTS7960 motor driver chip. One motor drive circuit uses two BTS7960 chips to form a full-bridge H-type drive system. At any time, only one MOSSFET power tube on the same bridge arm is turned on to control the forward and reverse rotation of the motor. The electro-hydraulic push rod we selected in the design can make the overall structure of the transfer bed compact, easy to install, and occupy a small space. It can be started with load, which will enable us to protect the equipment very well during operation. Such protection has specific significance in reality and is very important. The internal circuit of the electro-hydraulic push rod is equipped with a two-way hydraulic lock, which can stop at any position within the specified stroke range and self-lock, and keep the output force unchanged. The push-pull force and speed can be adjusted steplessly, which realizes the expansion of the force-driven range to a great extent, which is well reflected in our application in transfer beds.The electro-hydraulic push rod uses an electric motor as its power source. Through the forward (or reverse) rotation of the electric motor, the hydraulic oil outputs pressure oil through a bidirectional gear pump, which is assembled into blocks through the oil circuit and sent to the working cylinder to make the piston rod reciprocate. This working mode has achieved the maximum efficiency to a large extent and effectively realized our technical requirements. When the electro-hydraulic push rod is working, if the external force applied to the piston rod exceeds the rated output force or the piston has reached the end, the motor is still rotating. At this time, the oil pressure in the oil circuit increases to the set pressure, and the relief valve overflows quickly and accurately, which well maintains the purpose of safety protection in specific operations. The electro-hydraulic push rod is a hydraulically driven manipulator that integrates machine, electricity and liquid. It is suitable for reciprocating push-pull linear or reciprocating rotation at a certain angle.

[0060] Furthermore, the lifting base 100 in this embodiment needs to accurately connect the transfer bed and the imaging diagnostic bed. A stepper motor can be used as the main lifting mechanism of the transfer bed to drive the overall lifting of the mounting frame 200; the stepper motor is an open-loop control element that converts an electrical pulse signal into an angular displacement or a linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, which is called the "step angle". Its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, thereby achieving the purpose of accurate positioning. The stepper motor is an induction motor. Its basic working principle is: using a variety of electronic circuits, the dual-ring pulse signal converts the DC power of sufficient power into a time-sharing, multi-phase timing control current, and uses a pulse current to power the stepper motor to ensure the normal, stable and accurate operation of the stepper motor. The control system composed of a professionally designed power drive circuit is a multi-phase timing controller that powers the stepper motor in a time-sharing manner. The stepper motor cannot be directly connected to the industrial frequency AC or DC power supply, but must use a dedicated stepper motor driver, which consists of a pulse generation control unit, a power drive unit, a protection unit, etc. The two units are controlled by a single-chip microcomputer. The drive unit is directly coupled to the stepper motor. The base 000 is equipped with universal wheels for pushing;

[0061] Preferably, the JC35EM2 lifting column of Jiechang Company is selected, and the main parameters are as follows:

[0062] Load thrust:

[0063] JC35EM2-A / B: 4000N, 3000N, 2000N, 1500N, 1000N

[0064] JC35EM2-C: 6000N, 4000N, 3000N, 2000N, 1500N, 1000N

[0065] Load tension: None

[0066] Color: black / white / aluminum;

[0068] Stroke length: 100-600mm±3 (optional>600mm);

[0069] Installation dimensions:

[0070] Conventional configuration: L = S + 200 (S < 400), L = S + 220 (400 ≤ S < 600)

[0071] Special configuration: L = S + 250 (S > 600)

[0072] Noise Level:

[0073] JC35EM2-A / B: ≤55dB (ambient noise ≤45dB)

[0074] JC35EM2-C: ≤60dB (ambient noise ≤40dB)

[0075] Dual Hall feedback: optional

[0076] Push only, no pull function: No

[0077] Built-in electronic limit switch

[0078] Weight: Approximately 21.5kg for installation distance 950; (weight varies with different travel / installation distance)

[0079] Static bending moment: 500N.m.

[0080] Specifically, when in use, the control is carried out by the control end (which can be selected to be inherited to the transfer bed or the wireless control end), and the lifting base 100 drives the installation frame 200 to realize the overall lifting and lowering to achieve the adaptation relative to the height of the imaging device (such as a CT bed) to adapt to the height of the examination bed in the imaging room, typically such as the height adaptation to the CT bed. For example, after rising to the same height as the CT bed, the first drive mechanism 203 operates, so that the bed surface (the first bed board 301, the second bed board 401 and the third bed board 501) start to move parallel to the edge of the CT concave movable plate. After the lifting base 100 continues to rise by about 20 mm, the tilting electric hydraulic push rod (i.e., the second drive mechanism 207) starts to start and implement the tilting movement. After the patient is transferred to the concave CT bed, the transfer bed starts to return, slowly placing the patient in the appropriate position of the imaging equipment bed and then the whole machine exits; more specifically, the horizontal stepper motor (i.e., the first drive mechanism 203) starts to work to move the patient to the center of the imaging examination bed. When the patient is moved to the center of the examination bed (at this stage, the third drive mechanism 209 can move forward alone, so that it is faster and safer when leaving the patient), the tilting component (i.e., the second drive mechanism 207) starts to tilt, while tilting and returning in the horizontal direction (as mentioned above, at this stage, the third drive mechanism 209 can move backward alone), and the patient is slowly and steadily placed on the diagnosis bed. Then it enters the reset state, and the critically ill patients enter the medical examination module. The transfer bed module automatically enters the waiting state. The intelligent movement of the multifunctional transfer bed creates a more superior medical examination environment, provides a more reliable safety guarantee and a practical solution for the diagnosis of critically ill patients, and a new mode of intelligent lifting, moving, tilting and transporting eliminates the original manual method of pulling and dragging, so that the hospital's patient-centered quality service concept is fully reflected;

[0081] Preferably, after the patient examination is completed, the transfer bed is manually pushed to the side of the CT examination bed, and the control end recovery key is pressed, and the lifting base 100 drives the installation frame 200 to achieve overall lifting to match the height of the examination bed in the imaging room; then, the first drive mechanism 203 is operated, so that the bed surface (the first bed board 301, the second bed board 401 and the third bed board 501) begin to move parallel to the edge of the CT concave movable board, and after the lifting base 100 continues to rise by about 20 mm, the tilting electric hydraulic push rod (i.e., the second drive mechanism 207) performs a tilting movement to facilitate the transfer of the patient to the bed surface; then, a hard PVC strip is used to push the patient from under the patient along the CT concave movable bed to the other side of the patient, Medical staff will buckle the hard PVC strip with the PVC strip that is synchronously transferred from the patient to facilitate the transfer of the patient, and then transfer the patient to the bed surface. At this stage, the third driving mechanism 209 can move independently, which is more convenient for the patient to move to the third bed board 501 on the bed surface. Then the third driving mechanism 209 returns to operate to return the patient to its original position. After the third driving mechanism 209 drives the third bed board 501 to be in the same plane with the first bed board 301 and the second bed board 401, the second driving mechanism 207 operates to reduce the inclination of the bed surface until it reaches a normal state. Then the first driving mechanism 203 operates to retract the bed surface. At this point, the transfer bed completes the transfer of the patient after examination and can be moved.

[0082] In another preferred embodiment of the present invention, a sensor, such as a diffuse reflection infrared sensor, can be installed on the mounting frame 200 or the base 000, and a control mechanism is provided in the transfer bed, which can automatically control the operation when the sensor is detected to be close to the CT bed; specifically, when in use, when the sensor senses that the lifting base 100 is close to the imaging examination equipment, the control mechanism controls the lifting base 100, so that the lifting base 100 drives the mounting frame 200 to achieve overall lifting and lowering, so as to achieve height adaptation relative to the imaging equipment (such as a CT bed), so as to adapt to the height of the examination bed in the imaging room, typically such as adapting to the height of the CT bed, such as rising to the same height as the CT bed (the height can be detected by the sensor), the control mechanism starts to control the first drive mechanism 203 to operate, so that the bed surface (the first bed board 301, the second bed board 401 and the third bed board 501) start to move parallel to the edge of the CT concave movable plate, and the control mechanism starts to continue to control the lifting base 100 to rise by about 20 mm, and then continues to control the tilting electric hydraulic push rod (i.e., the second drive mechanism 207) to start and implement the tilting movement;

[0083] After the patient is transferred to the concave CT bed, the transfer bed starts the return movement phase, slowly placing the patient to a suitable position on the imaging device bed and then the whole device exits; more specifically, the control mechanism starts to control the horizontal stepping motor (i.e., the first drive mechanism 203) to start working to move the patient to the center of the imaging examination bed, and when the patient is moved to the center of the examination bed (at this stage, the third drive mechanism 209 can move forward alone, so as to be faster and safer when leaving the patient);

[0084] Afterwards, the control mechanism starts to control the tilting assembly (i.e., the second drive mechanism 207) to start the tilting operation, while tilting and returning in the horizontal direction (as mentioned above, the third drive mechanism 209 can be moved back alone at this stage), and the patient is placed slowly and steadily on the diagnostic bed. Then it enters the reset state, and the critically ill patients enter the medical examination module. The transport bed module of the transport vehicle automatically enters the waiting state. After the examination is completed, the control mechanism starts to control each drive mechanism to operate, and realizes the operation of driving the patient back to the transport bed.

[0085] The present invention realizes the lifting, translation and tilting of the first bed board, the second bed board and the third bed board through the lifting base, the first driving mechanism, the second driving mechanism and the third driving mechanism, and the third bed board can be tilted and retreated independently, so that the patient can be placed on the examination bed of the imaging equipment in a very stable and safe manner; it solves the traditional state of manual movement and transportation of critically ill patients during imaging examinations for many years, effectively reduces the workload of front-line medical nurses and imaging doctors, and has low production cost, simple structure, reliable source of parts and components, and stable operation; it improves the overall management level of the hospital and the image of high-quality service.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
