[0023] DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail with reference to the following examples. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0025] In an exemplary embodiment, first refer to Figure 1-2 A mobile hospital bed with guardrails includes a bed body that can support a patient or a person under examination, and guardrail mounting frames 301a and 301b are fixedly connected to the bed body on both sides along the length direction. The guardrail mounting frames 301a and 301b can be welded, riveted, bolted, etc. to the bed body, or can be integrally formed with the bed body, which all fall within the scope of fixed connection. The guardrail 302 and the guardrail mounting frames 301a and 301b are rotatably connected to each other, see in particular Figure 2 The guardrail 302 rotates and stops at least in the vertical protection position 101, the horizontal auxiliary position 102 and the guardrail recovery position 103, and this stop is completed by the locking mechanism. Figure 3The locking mechanism includes a locking block 401 that can move relative to each other and at least one locking groove. The locking block 401 is located at the guardrail 302, and the locking groove is located at the guardrail mounting frames 301a and 301b. When the locking block 401 is inserted into the locking groove, the guardrail 302 will be locked relative to the guardrail mounting frames 301a and 301b. In this way, the guardrail 302 can be locked and stopped in the vertical protection position 101, the horizontal auxiliary position 102 and the guardrail recovery position 103; when the locking block 401 leaves the locking groove, the guardrail 302 can rotate around the rotation axis relative to the guardrail mounting frames 301a and 301b.
[0026] In an exemplary embodiment, see Figure 3 , a rotating shaft 403 is fixed on the guardrail mounting frame 301a, and the rotation center of the rotating shaft 403 is the rotating axis; the locking block 401 has a rotating shaft groove, and the rotating shaft 403 passes through the rotating shaft groove and rotates in the rotating groove. In particular, the locking block 401 can be a flat key structure, in which the rotating shaft groove is an elongated rotating shaft slot 404, so that the rotating shaft 403 can perform two kinds of movements in the rotating shaft slot 404, namely rotation and sliding. When the rotating shaft 403 rotates in the rotating shaft slot, it can be particularly seen Figure 5-6 The locking block 401 rotates around the rotating shaft 403 in the circular accommodation space of the guardrail mounting frame 301a; when the rotating shaft 403 slides in the rotating shaft sliding groove 404, the locking block 401 slides in and out of the locking groove, and the angle of the guardrail 302 can be locked by sliding into the locking groove.
[0027] In one exemplary embodiment, see in particular Figure 3 There are two locking grooves, namely a horizontal locking groove 402a and a vertical locking groove 402b. The locking block 401 has a first end and a second end in the length direction of the shaft slide groove 404. The guardrail 302 is formed by extending along the second end direction of the shaft slide groove 404. Figure 4 , the first end is located in the horizontal locking groove 402a, and the guardrail 302 is located in the horizontal auxiliary position 102 in the horizontal direction. Figure 7 , the first end is located in the vertical locking groove 402b, and the guardrail 302 is located in the vertical protection position 101 in the vertical direction. Figure 5 , the second end is located at the vertical locking groove 402b, and the guardrail 302 is located at the guardrail recovery position 103 in the vertical direction. Figure 5-6, when neither the first end nor the second end is located in any locking groove, the locking block 401 can freely rotate around the rotating shaft 403 in the circular accommodation space of the guardrail mounting frame 301a, thereby rotating from one locking position to another locking position. The design of this embodiment uses two locking grooves to achieve locking of three locking positions. Furthermore, the rotating shaft slot 404 has a rotation position and a stop position. The rotation position is located in the middle position of the rotating shaft slot. There are two stop positions, which are respectively located at the two ends of the rotating shaft slot 404. When the rotating shaft 403 is in the rotation position of the rotating shaft slot 404, the locking block 401 rotates around the rotating shaft 403 in the circular accommodation space of the guardrail mounting frame 301a; when the rotating shaft 403 is in the stop position of the rotating shaft slot 404, the locking block 401 extends into the locking slot 402a or 402b to lock the guardrail 302. There are many ways to realize the rotation position and the stop position. For example, the rotation shaft slide groove 404 is used to form depressions at the rotation position and the stop position, and the rotation shaft 403 will be stopped at the corresponding position when it moves to these depressions. It is also possible to use magnets or electromagnets to form a force to stop the rotation shaft 403 at the rotation position and the stop position. These means can also be used in combination. Compared with the rotation position, the stop position is more necessary. When locking the guardrail 302, the stop force is required to maintain the guardrail in the locked position.
[0028] In an exemplary embodiment, there are not only two locking grooves, but three or more, which are evenly or unevenly distributed along the circumference of the circular accommodation space for accommodating the locking block 401 to rotate along the guardrail 302. The locking block 401 can be a flat key structure, and its first end and second end in the length direction of the rotating shaft slot 404 can slide into these locking grooves respectively, thereby locking the position of the guardrail 302. In the solution of this embodiment, more locking positions are provided for medical staff to choose in actual work.
[0029] In an exemplary embodiment, a damper is also provided to provide damping for the rotation of the rotating shaft 403 to provide a better handling feel and prevent the guardrail 302 from falling off in the free rotation position. Figure 5 After the medical staff moves the guardrail 302 along the unlocking direction A, the guardrail 302 enters a free rotation position where it can rotate freely. At this time, the medical staff will rotate the guardrail 302 to another position. During this process, the medical staff may release the guardrail 302 by mistake. At this time, the damper can prevent the guardrail 302 from suddenly falling back to the guardrail recovery position 103, and this sudden fall may cause injury.
[0030] In an exemplary embodiment, all operations are performed by a motor, which may include multiple motors, one for controlling the rotation of the rotating shaft 403, and an additional motor for controlling the locking block 401 to enter and exit the locking groove. This automated method only requires medical staff to indicate through buttons or applications whether the bed needs to be in the vertical protection position 101, the horizontal auxiliary position 102, or the guardrail recovery position 103, and the rest is automatically completed by the system. In the scenario where the patient is undergoing an examination, before the examination begins, the system can automatically control the guardrail 302 to be in the vertical protection position 101, and after the examination is completed, the guardrail 302 automatically returns to the guardrail recovery position 103.
[0031] In one exemplary embodiment, see in particular Figure 3-7 , a multi-position locking structure of a patient guardrail for a mobile bed is described in detail. The structure can set multiple guardrail stop positions according to needs, which are used to provide protection or be adjusted and selected as a shelf (horizontal auxiliary position 102) during medical activities. The locking mechanism can complete the locking and unlocking operations by controlling the relative position of the locking combination structure. The structure is simple and reliable, and the operation is easy. Specifically, the locking mechanism uses a movable locking block 401 and a fixed locking groove for locking and unlocking. The locking block 401 can be fixed to the connecting arm 303 of the guardrail 302, and is designed as a sliding structure or as a retractable movable part, which is driven in and out of the locking position manually or electrically. The locking groove is set on the guardrail mounting frame 301a, 301b.
[0032] See especially Figure 3 , which is an implementation of the sliding structure. The locking block 401 is arranged on the guardrail connecting arm 303, which is similar to a flat key, or can be of other shapes to adapt to different installation spaces and locking angle requirements. The locking groove (including the horizontal locking groove 402a and the vertical locking groove 402b) is arranged on the guardrail mounting frame 301a, which can be designed to be similar to a keyway with a flat key, or with other shapes of the locking block. According to requirements, one or multiple locking grooves in different positions can be set. The rotating shaft 403 is arranged at the center of the guardrail mounting frame 301a to provide rotation support after unlocking. The rotating shaft slide groove 404 is arranged on the guardrail connecting arm 303 to provide guidance for the sliding unlocking of the guardrail 302. See Figure 2 The locking positions mainly include the guardrail recovery position 103, the horizontal position auxiliary position 102 and the vertical protection position 101. Other locking positions can also be set according to specific needs. For the sliding locking block, the locking device can be unlocked by lifting (see Figure 5), rotate to other locking positions. If the locking block is a retractable component, the retracting action of the locking block can be driven by the operator pulling a wire or pressing a button to control the motor, which will not be repeated here. Of course, a counterweight spring can be added to make the operation easier. A damper can also be added to improve the operating comfort during the rotation process. Or a position retention mechanism can be added after locking to prevent accidental release from the locked state. Or a fully automatic mechanism can be used. After selecting the position through the human-computer interaction interface, the unlocking, self-driven rotation, and then locking operations can be automatically completed.
