Detailed Description

The following provides a further detailed description of a hospital bed and a medical device according to the present invention with reference to the accompanying drawings and embodiments. The advantages and features of the present invention will become more apparent from the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and clearly facilitating the description of the embodiments of the present invention.

Fig. 1 is a schematic structural view of a hospital bed according to an embodiment of the present invention, fig. 2 to 3 are sectional views of the hospital bed shown in fig. 1 when the hospital bed is oriented to a plane a of a base, and fig. 4 is a sectional view of the hospital bed shown in fig. 1 when the base is oriented to a plane B.

Referring first to fig. 1, the hospital bed in this embodiment includes a base 100 disposed at the bottom of the hospital bed, the base 100 being used to support the entire hospital bed. In this embodiment, the base 100 has a movable portion, so the movable portion can also be used to move the supporting mechanism 200 and the bed board 300 above the movable portion.

Referring to fig. 2 to 4, the base 100 specifically includes a fixing portion 110 and a movable portion 120 mounted on the fixing portion 110. The fixed portion 110 is used for supporting the movable portion 120 and allowing the movable portion 120 to move back and forth on the fixed portion 110.

Referring to fig. 3 and 4 with emphasis, the fixing portion 110 is provided with a guide rail 111 extending along a predetermined direction (e.g., the X direction shown in fig. 1). A plurality of sets of rollers 121 are disposed on the movable portion 120, and the plurality of sets of rollers 121 are arranged along the predetermined direction (X direction) and roll along the guide rail 111 to guide the movable portion 120 to move. Alternatively, the guide rail 111 may include a convex rail extending in a predetermined direction, and the roller 121 may be a concave wheel matched with the convex rail.

In this embodiment, the plurality of sets of rollers 121 are specifically disposed at the bottom of the movable portion 120 and are matched with the guide rail 111 so as to be movable along the direction defined by the guide rail 111. Wherein the roller 121 is fixedly installed at the bottom of the movable portion 120 by a screw, for example.

Further, at least one port of the guide rail 111 is an open port for moving a part of the roller 121 out of the guide rail 111 from the open port. That is, at least one roller 121 near the front end among the plurality of sets of rollers 121 may move out of the guide rail 111 such that the movable stroke of the roller 121 at the front end exceeds the boundary of the guide rail 111. In this way, the moving stroke of the movable part 120 is not limited in the guide rail 111, and the movable part can move to a further position, so that the moving stroke of the movable part 120 is extended, and accordingly the moving stroke of the bed plate 300 is extended.

Specifically, the plurality of sets of rollers 121 roll on the guide rail 111 in a direction toward the open port, and as the movement is continued, the front rollers 121 are sequentially moved out of the guide rail 111 to realize an ultra-long stroke of the movable portion 120. In this embodiment, when the movable portion 120 reaches the farthest stroke position, at least one roller 121 near the front end of the plurality of rollers 121 moves out of the guide rail 111, and at least one roller 121 near the rear end of the plurality of rollers 121 is still located in the guide rail 111, so that linear guiding can be achieved based on the rollers 121 in the guide rail 111, and the movable portion 120 can still linearly return along the path of the guide rail 111.

In this embodiment, one of the ports of the guide rail 111 is an open port from which a portion of the roller 121 can move, while the other port of the guide rail 111 is a closed port that does not allow the roller to move out. For example, fig. 2 illustrates the movable portion 120 in its initial position of travel; fig. 3 shows that the front roller of the movable part 120 moves out of the guide rail 111 to the furthest travel position, while the rear roller 121 is still in the guide rail 111. In a specific aspect, a stop may be disposed on the closing port to limit a movement end point of the roller 121, so as to prevent the roller 121 from moving out of the closing port.

With reference to fig. 4, at least two parallel guide rails 111 are disposed on the fixed portion 110, each set of rollers 121 on the movable portion 120 includes at least two rollers, and the at least two rollers 121 roll on the at least two guide rails 111 respectively, so as to improve the stability of the movable portion 120. Specifically, the fixing portion 110 has, for example, a side plate 112 extending along the predetermined direction (X direction), and the guide rail 111 is provided on the side plate 112. In this embodiment, the fixing portion 110 has two opposite side plates 112, and two opposite guide rails 111 are disposed on inner walls of the two opposite side plates 112.

In an alternative embodiment, the guide rail 111 includes a convex rail extending along a predetermined direction, and the convex rail protrudes relative to the inner wall of the side plate 112. And, the roller 121 specifically includes a concave wheel, a rotation shaft of the concave wheel is vertically disposed, and a groove of the concave wheel is laterally engaged with the convex rail to rotate along the convex rail.

In this embodiment, the roller 121 is laterally engaged with the guide rail 111, so that the roller 121 rotates along a vertical rotation axis. However, in other embodiments, the roller may be engaged above the guide rail, for example, so that the roller rotates along the rotation axis in the horizontal direction.

In a further aspect, a support wheel (not shown) is further disposed on an end of the movable portion 120 for supporting the movable portion 120 at an end position of the movable portion 120. Specifically, the support wheels may be provided on the end of the movable part 120 corresponding to the open port of the guide rail 111, so that the support wheels may support the movable part 120 at the end position after the end roller 121 is moved out of the guide rail 111, ensuring the stability of the movable part 120. Alternatively, the support wheel may be a retractable support wheel for extending after the end roller 121 is moved out of the guide rail 111 to support the movable portion 120. That is, when the plurality of sets of rollers 121 are all in the guide rail 111 (for example, the state shown in fig. 2), the supporting wheels can be retracted; when the front roller 121 moves out of the guide rail 110 (for example, in the situation shown in fig. 3), the support wheel can be extended to roll and support, and the moving state of the movable portion 120 is maintained.

With continued reference to fig. 1, the medical bed further comprises a support mechanism 200, wherein the support mechanism 200 is disposed on the base 100 and is used for supporting a bed board 300 of the medical bed. In this embodiment, the supporting mechanism 200 includes a height adjusting device for adjusting the height of the bed board 300.

Further, a support plate is further disposed below the bed plate 300, and is used for supporting the bed plate 300. In one embodiment, the bed plate 300 may be a movable bed plate so as to be movable on the support plate in a predetermined direction, such that a movable stroke of the bed plate 300 is overlapped by a movable stroke of the movable portion 120 in the base 100, which greatly extends a total stroke of the bed plate 300 with respect to the support plate. It should be noted that, because the movable portion 120 in the base 100 has a longer moving stroke, the moving stroke of the automatic translation of the bed board 300 (i.e., the movement of the bed board 300 relative to the support plate) can be correspondingly reduced, and even the bed board 300 can be fixed relative to the support plate, so that the problem of the stability reduction of the bed board due to the larger moving distance of the automatic translation of the bed board can be effectively solved.

In summary, in the medical bed provided by the embodiment, the movable portion 120 of the base 100 can move relative to the fixed portion 110, and part of the rollers 121 on the movable portion 120 can also move out of the guide rail 111 of the fixed portion 110, so that the moving stroke of the movable portion 120 is not limited in the guide rail 111 and can extend out of the guide rail, the moving stroke of the movable portion 120 is greatly prolonged, and the moving stroke of the bed plate 300 is correspondingly prolonged, which is beneficial to realizing an ultra-long stroke of the medical bed. Meanwhile, the super-long stroke of the medical bed can be realized in the original size (or smaller size) of the medical bed, the occupied area of the medical bed is reduced, and the design space is saved.

Based on the medical bed, the embodiment also provides medical equipment with the medical bed. The medical apparatus having the medical bed as described above in the present embodiment will be described in detail below by taking a specific example. Fig. 5 may be specifically referred to, and fig. 5 is a schematic structural diagram of a medical device in an embodiment of the present invention.

As shown in fig. 5, the medical apparatus in the present embodiment may include a radiotherapy apparatus including a main body support 20, a radiotherapy assembly 30 and an imaging assembly 40 connected to the main body support 20. And the radiotherapy equipment also comprises a medical bed 10, wherein the medical bed 10 is arranged on one side of the main body support 20. Specifically, a cavity 20a is further defined in the main body frame 20, and the bed board 300 of the medical bed 10 can extend into the cavity 20 a.

In this embodiment, the radiotherapy assembly 30 is disposed on a first side of the main body support 20. In the specific example, the radiotherapy assembly 30 includes a treatment arm 31, a treatment head 32, and a portal imaging unit 33. One end of the treatment arm 31 is fixed on the main body bracket 20, the other end of the treatment arm 31 extends outwards, and the treatment head 32 is fixed at the other end of the treatment arm 31. The portal imaging unit 33 is opposite to the treatment head 32 in the radiation treatment state to receive the outgoing beam of the treatment head 32.

Further, the imaging assembly 40 is mounted to a second side of the body support 20. In a specific example, the imaging assembly 40 is a CT imaging assembly that includes at least an X-ray tube and a detector in opposing arrangement. Of course, in other examples, the imaging assembly 40 may be an MR imaging assembly or a Positron Emission Tomography (PET) imaging assembly.

In this embodiment, the couch board 300 of the couch 10 is translatable between the imaging position of the imaging assembly 40 and the treatment position of the radiotherapy assembly 30. Specifically, when imaging is performed using the imaging assembly 40, the couch 300 may be moved toward the main body frame 20 and to the imaging position of the imaging assembly 40 to facilitate imaging scanning. And, after imaging, the couch 300 may be linearly moved from the imaging position to the treatment position of the radiotherapy assembly 30 for radiation treatment.

It should be appreciated that the moving process of the bed plate 300 is substantially realized by the movable portion 120 below the bed plate 300, i.e., by controlling the movable portion 120 in the base 100 to move linearly relative to the fixed portion 110, so as to move the bed plate 300 above the fixed portion linearly. Therefore, the condition of the bed plate 300 can be prevented from being changed due to the long distance of the automatic translation of the bed plate 300. For example, in this embodiment, the distance of the self-translation of the couch plate 300 is short, and the stability is high, so that the state of the couch plate 300 at the imaging end and the radiotherapy end can be kept consistent.

It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other. Moreover, the above description is only intended to illustrate the preferred embodiments of the present invention, and not to limit the scope of the present invention, and it will be apparent to those skilled in the art that many changes and modifications can be made in the technical solutions of the present invention without departing from the scope of the present invention, or equivalent embodiments modified by the technical solutions disclosed above. Therefore, any simple modification, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention, where the technical entity does not depart from the content of the technical solution of the present invention.
