Abstract
Description
Technical Field
[0001] This application relates to mobile institutions, and more particularly to a patient mobility device and medical system. Background Technology
[0002] In current medical imaging procedures, especially for patients with limited mobility or critical conditions, it is usually necessary to transfer them from their hospital beds to the mounting bed of imaging scanning equipment (such as CT scanners, MRI machines, etc.) for relevant examinations. The commonly used procedure is to move the patient's bed to one side of the mounting bed of the scanning equipment and place it side by side; then, multiple medical staff will work together to lift and pull the bed sheets to transfer the patient entirely to the mounting bed of the scanning equipment.
[0003] However, this traditional transfer method has many shortcomings. First, the procedure requires at least 4 to 6 medical staff to work together, resulting in high manpower demands and low efficiency, especially in high-intensity work environments such as emergency rooms or intensive care units, which seriously affects the rational allocation and efficient use of medical resources. Second, frequent physical handling can negatively impact the health of medical staff, easily leading to occupational injuries such as musculoskeletal disorders. Furthermore, this transfer method lacks stability and comfort for the patient, as it can easily generate significant body swaying or friction during the transfer, potentially causing discomfort or even secondary injuries, such as catheter dislodgement, aggravated fractures, and skin pressure sores.
[0004] Therefore, there is an urgent need to provide a patient transfer device or system that is structurally sound, easy to operate, safe, and efficient, in order to overcome the aforementioned deficiencies in the existing technology and improve the safety, comfort, and efficiency of the medical transport process.

[0025] The following specific examples illustrate the implementation of this application. Those skilled in the art can readily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0027] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.
[0028] The inventors of this application have discovered that current patient mobility methods typically require significant manpower, are inefficient, lack stability and comfort, and are prone to causing secondary injuries, especially for critically ill patients. Therefore, to address these technical problems, this application creatively provides a patient mobility device, the implementation methods of which will be described in detail below.
[0029] like Figure 1 The diagram shown is a schematic representation of a patient mobility device according to an embodiment of this application. The patient mobility device is used to smoothly transfer a patient from a hospital bed or other location to a target medical device, such as an imaging scanning device support bed or other medical transport target location. The patient mobility device includes a lifting mechanism 10 and a patient support mechanism 20. The lifting mechanism 10 includes a moving mechanism 101, a cable component 102, and a first connecting mechanism 103 (e.g., ...). Figure 4The moving mechanism 101 includes a guide rail 1010 and a sliding part 1011. One side of the sliding part 1011 is slidably connected to the guide rail 1010, and the other side is connected to the cable component 102. The guide rail 1010 is fixedly connected to a preset mechanism (e.g., a roof), allowing the sliding part 1011 to slide on it to move the patient support mechanism 20. The sliding part 1011 is, for example, an electric or manual sliding rail trolley structure, adapted and installed within the guide rail 1010, and can move within the guide rail 1010 within a set range. The cable component 102 is a high-strength flexible material such as steel wire rope, synthetic fiber rope, or composite rope, possessing good load-bearing capacity and flexibility. The first connecting mechanism 103 is disposed at the other end of the cable component 102 relative to the moving mechanism 101, for connecting to the patient support mechanism 20, and may employ, for example, a snap-fit quick-connect structure or a threaded locking structure. By controlling the movement of the sliding part 1011 along a predetermined trajectory within the guide rail part 1010, the cable member 102 can be translated, thereby driving the patient support mechanism 20 connected thereto to move towards the target area.
[0030] Combination Figure 2 The diagram shows the patient support mechanism 20 in its open state. The patient support mechanism 20 includes a patient support section 201 and a second connecting mechanism 202 connected to the patient support section 201. The second connecting mechanism 202 is used to connect to the first connecting mechanism 103 to move the patient support mechanism 20 to a target area via the moving mechanism 101. The patient support section 201 includes at least two separable bed board sections, such as a first bed board section 2011 and a second bed board section 2012, which can be separated laterally along a transverse direction H. Each bed board section has an edge portion (unlabeled) that abuts against the adjacent bed board section. The edge portion includes a insertion portion 2013 and a receiving portion 2014. The receiving portion 2014 is, for example, a groove, and the insertion portion 2013 is, for example, a sheet-like body. Figure 3 The diagram shows the assembled state of the patient support mechanism. An insertion portion 2013 on the edge of one bed board section (e.g., the first bed board section 2011) is inserted into a receiving portion 2014 on the edge of another adjacent bed board section (e.g., the second bed board section 2012) to fix the vertical and front-back positional relationship between the adjacent first bed board sections 2011 and second bed board sections 2012. In some aspects, each bed board section 201 has multiple insertion portions 2013 and receiving portions 2014, and adjacent insertion portions 2013 are spaced apart by receiving portions 2014.
[0031] In some aspects, the patient support mechanism 20 includes a first pair of opposite ends 203 and a second pair of opposite ends 204, wherein the length of the first pair of opposite ends 203 is less than the length of the second pair of opposite ends 204, and each of the first pair of opposite ends 203 is provided with a fastening element 205. Figure 3 (As shown), it is used to fix adjacent bed board portions 201 together to prevent them from separating laterally. The first bed board portion 2011 and the second bed board portion 2012 each have at least one first vertical wall 2031 and a second vertical wall 2032 with arc-shaped edges at their first two opposite ends 203. At least a portion of the first vertical wall 2031 and the second vertical wall 2032 gradually increase in height from both sides towards the center. Figure 2 As shown, the fastener 205 includes a rotatable locking part 2051 and a mating part 2052 for connecting with the locking part. The locking part 2051 and the mating part 2052 are respectively disposed on the vertical walls 2031 of adjacent bed board sections. For example, if the locking part 2051 is disposed on the vertical wall 2031 of the second bed board section 2012, then the mating part 2052 is disposed on the vertical wall 2032 of the first bed board section 2012. Similarly, the reverse arrangement is also possible, which will not be elaborated further here. In some aspects, the head end of the locking part 2051 is hook-shaped, and the mating part 2052 is column-shaped. The hook-shaped head end of the locking part 2051 can lock the column-shaped mating part 2052, thus preventing adjacent bed board sections 201 from separating laterally.
[0032] Of course, as those skilled in the art will understand, adjacent bed board sections 201 can also be detachably connected using hinges, slide rails, or quick-release mechanisms. In some aspects, the surface of the bed board section 201 can be covered with padding or medical fabric to improve patient comfort and safety.
[0033] Combination Figure 4 As shown, the second connecting mechanism 202 is used to connect with the first connecting mechanism 103, and the connection between the patient support mechanism 20 and the lifting mechanism 10 is realized through the cable member 102. Specifically, there are multiple second connecting mechanisms 202 and first connecting mechanisms 103, forming a multi-point suspension structure to ensure uniform force distribution and prevent tilting. As those skilled in the art will understand, the first connecting mechanism 103 and the second connecting mechanism 202 can also be non-detachable, or the two can be connected as a single unit.
[0034] return Figure 1As shown, in some aspects, the lifting mechanism 10 also includes a lifting adjustment assembly 104, located between the moving mechanism 101 and the cable member 102, for adjusting the height of the patient support mechanism 20. The lifting adjustment assembly 104 can be an electric winch, hydraulic cylinder, or telescopic rod structure, capable of automatically or manually adjusting the vertical height of the patient support mechanism according to the height of the target bed, keeping it level with the target bearing surface and avoiding tilting or impact caused by height differences. This lifting adjustment assembly 104 is particularly suitable for different models of scanning equipment beds or transfer platforms, improving the versatility and adaptability of the device.
[0035] In some aspects, such as Figure 5 The diagram shows a block diagram of the control system structure of the patient mobility device 10. The patient mobility device 10 also includes a control system 105, which is electrically connected to the mobility mechanism 101 and the lifting adjustment assembly 104. The control system 105 includes one or more of the following components: a control panel 1050 for manual command input; a sensor assembly 1051, including a weight sensor, height sensor, and posture sensor, for real-time monitoring of the patient mobility device's operation; an automatic identification module 1052 for identifying patient identity information, scanning device model, and matching parameters; and an alarm module 1053 for issuing alarms in abnormal conditions (such as overload or excessive tilt angle). Through the aforementioned control system 105, the patient transfer process can be automated and intelligently operated, improving safety and efficiency.
[0036] During use, the patient's body is first turned to one side, and then the first bed board 2011 on the opposite side is placed under the patient's body. Next, the patient is turned to the other side, and the second bed board 2012 on the other side is inserted into the first bed board 2011, such that the insertion part 2013 on the edge of one bed board is inserted into the receiving part 2014 on the edge of the adjacent bed board, fixing the vertical position of the adjacent bed boards. Then, the rotatable locking parts 2051 of the latches 205 at both ends of the patient support are fastened onto the docking parts 2052, thereby preventing the adjacent bed boards from sliding to the sides or separating during use. Afterwards, the moving mechanism 101 can be activated to smoothly transfer the patient to the target position (such as a CT scan bed). After the transfer is completed, the first bed board 2011 and the second bed board 2012 are unlocked and transferred away from the target position by the lifting mechanism 10. Of course, in some cases, the two bed boards may not be unlocked and the bed boards may not be pulled out from under the patient's body. The patient support mechanism 20 may be detached from the lifting mechanism 10 and left on the target bed by disconnecting the second connecting mechanism 202 from the first connecting mechanism 103, so that it can be used for subsequent examination or treatment.
[0037] like Figure 6The diagram shown is a schematic representation of a second embodiment of the patient support mechanism provided in this application. In this embodiment, the patient support mechanism 20' includes at least two bed board sections that can be separated along the longitudinal direction L. In this embodiment, two bed board sections are used as an example for explanation, namely, an upper bed board section 201a and a lower bed board section 201b. The two are connected to each other by a quick-connect structure, such as a pin 2013' and a slot 2014', and a locking member 205'. The principle is the same as that of the insertion part 2013 and the receiving part 2014 described above, and will not be repeated here.
[0038] The other parts in this embodiment are the same as in the first embodiment, and therefore will not be described again. This embodiment allows for flexible adjustment of the support structure according to the patient's body shape or condition. For example, for fracture patients, only the bed board corresponding to the injured area can be retained, while the rest can be removed for easier local operation; it also facilitates transportation and storage.
[0039] In some aspects, the patient support mechanism 20 adopts a folding structure design, and the various bed panels can be connected by folding hinges (not shown), allowing it to be folded and stored when not in use, saving space. The lifting mechanism 10 is detachably mounted on a movable bracket (not shown), facilitating flexible transport and deployment between different wards or examination rooms.
[0040] Based on the above ideas, return Figure 1 As shown, this application also provides a medical system comprising: a medical device 30 for performing medical diagnostic or treatment procedures on a patient; and a patient mobility device as described above, the patient mobility device being driven to a desired position relative to the medical device 30. The medical device 30 may be, for example, a magnetic resonance imaging (MRI) system, a computed tomography (CT) scanner, a radiotherapy device, an ultrasound examination device, a surgical robot system, a dialysis machine, or other forms of medical instrument.
[0041] In summary, the patient transfer device disclosed in this application has the advantages of simple operation and ease of use, requiring only one operator to complete the patient transfer process, thus improving work efficiency. At the same time, the device is patient-friendly, operates smoothly during transfer, and effectively avoids secondary injury to the patient. Furthermore, the device has a reasonable structural design, is easy to install, has no special requirements for the site of use, is highly adaptable, and its usage mode can be reasonably adjusted according to the specific patient's condition, further enhancing its practicality and promotional value.
[0042] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
