Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a rotatable and adjustable handrail. Background Technology

[0002] Childbirth refers to the emergence of a new individual from the mother's body; specifically, it refers to the period and process of the fetus separating from the mother's body as an independent individual. The entire process of childbirth is divided into three stages, also known as the three phases of labor. The first stage of labor is the cervical dilation stage. The second stage of labor is the fetal expulsion stage. The third stage of labor is the placental expulsion stage, which refers to the process from the delivery of the fetus to the expulsion of the placenta.

[0003] During natural childbirth, the mother needs to hold onto the handrails next to the delivery bed to assist in the delivery. In current technology, the handrails of the delivery bed are generally fixed to the bed frame. However, the mother needs to adjust her body position during childbirth. After adjusting her position, the handrails cannot rotate, so they cannot adapt to the mother's adjusted position, making it difficult for the mother to exert force effectively. Moreover, the hand is prone to slipping when exerting force. Utility Model Content

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-7 As shown, the rotatable and adjustable handrail of this utility model includes a body 1, a shell 2 fixedly mounted on the body 1, a first cavity 3 disposed within the shell 2, a handle 4 rotatably mounted on the body 1, a second cavity 5 disposed within the handle, a groove 6 disposed within the body 1 for engaging the handle 4, trapezoidal sliders 7 disposed at both ends of the handle 4, guide grooves 8 disposed within the groove 6 for engaging with the trapezoidal sliders 7, a trapezoidal guide rail 9 fixedly mounted on the body 1, a circular plate 10 rotatably mounted on the body, a guide rail groove 11 disposed on the circular plate 10 for engaging with the trapezoidal guide rail 9, a locking device 12 disposed within the body 1 for locking the handle 4, and a fastening device disposed within the body 1 for securing the hand. 13. An opening groove 14 is provided on the main body 1; when the mother grips the handle, the locking device and the fastening device are applied simultaneously, and the locking device and the fastening device open simultaneously, thereby fixing the handle and the mother's hand at the same time. On the one hand, it protects the mother's hand from slipping and being injured when excessive force is applied, and on the other hand, it protects the handle from being injured. When the mother needs to adjust the position, she can rotate the handle and adjust it to a suitable position. When she squeezes the handle tightly, it fixes the handle and the mother's hand again. The handle, trapezoidal slider and guide groove are provided to allow the handle to rotate. The trapezoidal guide rail and guide rail groove are provided to make the handle more stable when rotating.

[0030] Specifically, the locking device 12 includes a rubber brake pad 121 fixedly disposed in the first cavity 3, a first through pipe 122 and a second through pipe 123 fixedly disposed through both ends of the circular plate 10, a third through pipe 124 fixedly disposed at both ends of the first through pipe 122 and the second through pipe 123 and communicating with them, a plurality of first telescopic chambers 125 arranged in a linear array at equal intervals on the third through pipe 124, a sealing plate 126 arranged in a linear array at equal intervals on the third through pipe 124 and cooperating with the plurality of first telescopic chambers 125 one by one, and a rubber soft pad 127 fixedly disposed on the handle 4 and covering the plurality of first telescopic chambers 125; when the mother squeezes the handle, the rubber soft pad moves downward under force, thereby driving the first telescopic chamber to be compressed under force, causing the air in the first telescopic chamber to be compressed under force and rush into the third through pipe, and the air enters the first through pipe and the second through pipe simultaneously through the third through pipe, thus ventilating the first through pipe and the second through pipe.

[0031] Specifically, the locking device 12 further includes a second telescopic cavity 128 fixed at one end to the first through pipe 122, a first rubber brake block 129 fixed at the other end of the second telescopic cavity 128, a first return spring 1210 fixed at both ends of the second telescopic cavity 128, a third telescopic cavity 1220 fixed at one end to the second through pipe 123, a second rubber brake block 1230 fixed at the other end of the third telescopic cavity 1220, and a second return spring 1250 fixed at both ends of the third telescopic cavity 1240. The first telescopic cavity is connected through the handle. After air flows into the second telescopic cavity from the first through pipe, it drives the second telescopic cavity to move, thereby driving the first rubber brake block to move. Finally, the first rubber brake block contacts the rubber brake pad. After the two contacts, the friction increases, achieving the effect of locking the handle.

[0032] Specifically, the fastening device 13 includes an air chamber 131 fixedly mounted on and communicating with the handle 4, a rubber slider 132 slidably mounted within the air chamber 131, a rubber airbag 133 fixedly mounted on the circular plate 10, a first short tube 134 fixedly mounted on and communicating with one end of the handle 4, a second short tube 135 fixedly mounted on and communicating with the other end of the handle 4, a first air inlet pipe 136 fixedly mounted on one end of the first short tube 134 and used to communicate with the rubber airbag 133, and a second air inlet pipe 137 fixedly mounted on one end of the second short tube 135 and used to communicate with the rubber airbag 133; when the mother puts her hand into this utility model... When the hand is inserted into the rubber air bladder, the distance between the air bladder and the hand is relatively small due to the design of the air bladder, thus providing a certain degree of fixation. After the rubber slider is gripped, the air inside the air chamber rushes into the first and second short tubes through the second cavity inside the handle. The air inside both enters the first and second air inlets simultaneously, and the air inside the first and second air inlets rushes into the rubber air bladder at the same time. The rubber air bladder expands and comes into contact with the back of the mother's hand and the outer side of her fingers. It continues to expand, eventually wrapping around the entire back of the mother's hand, thereby preventing the mother's hand from slipping.

[0033] Specifically, the guide groove is provided with limiting plates at both ends; the limiting plates at both ends of the guide groove prevent the handle from slipping off when rotating.

[0034] Specifically, all exposed edges of the main body are rounded to ensure that the mother will not be injured by the corners of the body during childbirth.

[0035] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
