[0022] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following examples are provided to further elaborate on the present disclosure in detail. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0023] In an exemplary embodiment, specifically refer to Figure 1 , the horizontal module structure of the medical bed includes a bed board 10, a trailer 20, a frame 30, and a linear guide rail 40. The bed board 10 is fixed by the trailer 20. The trailer 20 slides on the linear guide rail 40, and the frame 30 is on both sides of the bed board 10 in the width direction. Among them, in order to increase the rigidity, the middle part of the bed board 10 is a wavy structure, which causes the middle part of the bed board to be uneven. When the examinee lies on the bed, a mattress needs to be added, resulting in poor comfort. The material of the trailer 20 is generally cast iron, which is formed by casting, durable but heavy. The frame 30 can also be called a bed frame. In this embodiment, the bed frame structure is not only complex and bulky, and there is a possibility of pinching the examinee in the gap between the bed frame and the hospital bed. Its precision requires high costs to control. In addition, the width of the frame 30 also affects the examinee getting on and off the bed, which is relatively disadvantageous for the examinee with inconvenient movement.
[0024] In an exemplary embodiment, specifically refer to Figure 2 , to overcome Figure 1 the problems existing in the embodiment shown, a borderless medical bed horizontal module is provided, eliminating the Figure 1 frame 30 in the embodiment, greatly reducing the weight. The horizontal module of this embodiment includes a bed board 1. The upper surface of the bed board 1 is designed as a flat and smooth plane. This smooth upper surface that can support the examinee can eliminate the mattress (of course, to improve the comfort of the patient, the mattress is not necessarily eliminated), further reducing the weight. To enhance the strength of the bed board 1, a smooth downward bend 7 is formed at the edges of the bed board 1 extending towards both sides in the width direction. This bend 7 can enhance the strength while avoiding harm to the patient from the sharp edge part. A trailer 2 is fixedly connected to the lower side of the bed board 1. The trailer 2 slides on the linear guide rail 4 along the length direction of the bed board 1, dragging the bed board 1 for horizontal movement. The weights of the bed board 1, the trailer 2, and the linear guide rail 4 are borne by the middle beam 3, and the middle beam 3 is fixedly connected to the linear guide rail 4. Since the frame is cancelled, the weight is reduced and the structure is greatly simplified.
[0025] In an exemplary embodiment, continue to refer to Figure 2 , the cross-section of the bed board 1 in the width direction is approximately arc-shaped. In the use state, it presents a shape with both sides high and the middle low, that is, the edge height of the bed board 1 in the width direction is higher than the center point of the bed board 1 in the width direction. Such a design makes it difficult for the examinee to roll off, playing a certain fixing role.
[0026] In an exemplary embodiment, refer to Figures 2 - 4, the bed board 1 is composed of three layers, which are sequentially composed of a first fiber layer, a foam layer, and a second fiber layer. Among them, the first fiber layer and the second fiber layer are carbon fiber layers. This sandwich structure is beneficial to enhancing the strength of the bed board 1.
[0027] In an exemplary embodiment, continue to refer to Figures 2 - 4 , the bed board 1 is divided into three regions in sequence from the left side to the right side in the width direction, namely the first region, the second region, and the third region. Among them, the first region and the third region are only composed of the first fiber layer and the second fiber layer, and are of a double-layer structure, while the second region is composed of the first fiber layer, the foam layer, and the second fiber layer, and is of a three-layer structure. The first region and the third region are symmetrically arranged on both sides of the second region. Since the person being examined often lies in the central position of the hospital bed, such a design reduces the overall thickness and weight of the bed board 1 while ensuring strength.
[0028] In an exemplary embodiment, particularly refer to Figures 3 - 4 , there are 3 bends in the first region and the third region respectively. Taking the third region as an example, among them, the first bend 5 is located at the junction of the second region and the third region, and is formed by the bend of the second fiber layer on the lower side, while the first fiber layer on the upper side remains smooth to ensure the comfort of the patient. This first bend 5 not only improves the strength of the bed board 1, but also effectively separates the second region containing the foam layer and the third region without the foam layer. The second bend 6 is arranged close to the edge in the width direction of the bed board 1. Since this place has left the area where the examiner lies, it is formed by the common bend of the first fiber layer and the second fiber layer. The third bend 7 is a smooth downward bend formed at the edge in the width direction, and the third bend 7 is also formed by the common bend of the first fiber layer and the second fiber layer, which is used to improve the strength of the bed board 1. The first region and the third region are symmetrically arranged, and will not be elaborated here.
[0029] In an exemplary embodiment, the trailer 2 is an aluminum extrusion part, which is very helpful for further lightening the weight of the hospital bed compared with cast iron parts. The trailer 2 and the bed board 1 are fixedly connected by bolts.
[0030] In an exemplary embodiment, a borderless medical bed is provided, which includes the horizontal module and the base of the borderless medical bed in the above embodiment, and the base is used to support the horizontal module of the borderless medical bed. In the base, a vertical direction module can also be included for the lifting movement of the bed board.
[0031] The specific embodiments of the present disclosure have at least the following characteristics:
[0032] 1. Adopt a borderless structure, reduce costs, reduce weight, and save assembly time;
[0033] 2. The upper surface of the bed board has an overall smooth concave design, which improves the comfort and sense of security of patients. The manufacturing process is simple, and it is easy to ensure uniformity, thereby improving the image quality.
[0034] 3. The two sides of the bed board adopt a downward-flipping form to increase rigidity; arc structures are added to both sides of the bed board to further improve the overall rigidity.
[0035] In the present disclosure, the orientation words such as "upper, lower, left, and right" are only exemplary relative directions in the drawings and do not represent the direction of gravity in the usage state. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another and do not have sequentiality and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as a limitation to the present disclosure. In addition, the nouns and pronouns related to people in the present disclosure are not limited to specific genders.
[0036] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict.
