[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1 to 4As shown, the utility model provides a position-changing bed for digestive endoscopy, including an examination bed 100 and a bed body 200. The examination bed 100 includes a rectangular bed board 110, telescopic legs 120 and a rectangular base 130. The bottom edge of the rectangular bed board 110 is provided with six first mounting portions 111, and the six first mounting portions 111 are evenly distributed on the two side edges of the bottom surface of the rectangular bed board 110. The top edge of the rectangular base 130 is provided with six second mounting portions 131 aligned with the first mounting portions 111. The length of the rectangular bed board 110 is greater than the length of the rectangular base 130, and the width of the rectangular bed board 110 is greater than the width of the rectangular base 130. The number of telescopic legs 120 is the same as the number of the first mounting portions 111. One end of the leg 120 is hinged to the first mounting portion 111, and the other end of the telescopic leg 120 is hinged to the second mounting portion 131; the bed body 200 is arranged on the rectangular bed board 110, and a plurality of pulleys 210 are arranged on the top surface of the bed body 200 along the width direction, and a sliding cloth 220 is arranged on the pulley 210, and support frames 230 are arranged on both sides of the bed body 200 along the width direction, and the support frames 230 are provided with a sliding opening 231, and both ends of the sliding cloth 220 pass through the sliding opening 231, and a pull rod 240 is arranged at the end of the sliding cloth 220 extending out of the sliding opening 231, and a chest restraint belt 221 and a leg restraint belt 222 are arranged on the sliding cloth 220.

[0030] The body position changing bed for digestive endoscopy provided by the utility model, during use, the patient lies on the sliding cloth 220, the patient's chest is fixed by the chest restraint belt 221, the patient's legs are fixed by the leg restraint belt 222, and the upper and lower heights, front and rear angles and left and right angles of the rectangular bed board 110 can be adjusted by adjusting the lengths of the six telescopic legs 120 respectively, so as to change the position of the rectangular bed board 110, and then realize the change of the position of the bed body 200, so as to adapt to the progress of the digestive endoscopy, meet different examination needs, and enhance the flexibility of diagnosis and treatment.

[0031] When the patient needs to change his position, the medical staff stands on the left or right side of the bed 200 and pulls the pull rod 240. The pull rod 240 drives the sliding cloth 220 to shift its position relative to the pulley 210, and the sliding cloth 220 drives the patient to rotate, thereby realizing the patient's rotation along the axis of the body. The medical staff does not need to directly move the patient's body, which is simple and labor-saving and reduces the patient's physical burden. In addition, since the patient is fixed to the sliding cloth 220 by the chest restraint belt 221 and the leg restraint belt 222, it can ensure that the patient remains in the desired position after the position adjustment, thereby avoiding the patient's deflection and affecting the medical staff's digestive endoscopy examination.

[0032] Since the length of the rectangular bed board 110 is greater than the length of the rectangular base 130, and the width of the rectangular bed board 110 is greater than the width of the rectangular base 130, a stable stepped structure is formed between the rectangular bed board 110, the telescopic legs 120 and the rectangular base 130, thereby preventing the rectangular bed board 110 from collapsing.

[0033] In some embodiments, the telescopic leg 120 includes a base 121 and a support seat 122, one end of the base 121 is hinged to the second mounting portion 131, a motor 1211 is arranged in the base 121, the motor 1211 is provided with a brake 1212, the output end of the motor 1211 is connected to the input end of the harmonic reducer 1213, the output end of the harmonic reducer 1213 is connected to a lead screw 1214, the lead screw 1214 is threadedly connected to a nut 1215, the nut 1215 is slidably connected to the base 121, one end of the support seat 122 is connected to the nut 1215, and the other end of the support seat 122 is hinged to the first mounting portion 111.

[0034] When the length of the telescopic leg 120 needs to be adjusted, the motor 1211 is started, and the motor 1211 drives the lead screw 1214 to rotate after being decelerated by the harmonic reducer 1213. Since the lead screw 1214 is threadedly connected with the nut 1215, the lead screw 1214 drives the nut 1215 to slide relative to the slide seat, and the nut 1215 drives the support seat 122 to move, thereby adjusting the length of the telescopic leg 120. Considering the safety design, when there is a sudden power failure or the program runs away, the motor 1211 suddenly stops working, and the brake 1212 set on the motor 1211 realizes the position locking function, and the telescopic leg 120 can quickly stop working and lock the position to avoid hurting the patient. Exemplarily, the lead screw 1214 can be, but not limited to, a ball screw.

[0035] In some embodiments, a dustproof sleeve 1216 is provided at one end of the base 121 away from the second mounting portion 131, and the dustproof sleeve 1216 is sleeved on the support seat 122. By providing the dustproof sleeve 1216, dust can be prevented from entering between the lead screw 1214 and the nut 1215, thereby ensuring the movement accuracy of the lead screw 1214 and the nut 1215 and ensuring the stability and reliability of the telescopic leg 120.

[0036] In some embodiments, a first universal joint 1217 is provided at one end of the base 121 facing away from the support seat 122, and the base 121 is hinged to the second mounting portion 131 through the first universal joint 1217. A second universal joint 1221 is provided at one end of the support seat 122 facing away from the nut 1215, and the support seat 122 is hinged to the first mounting portion 111 through the second universal joint 1221, thereby ensuring the connection flexibility between the telescopic leg 120 and the first mounting portion 111 and the second mounting portion 131.

[0037] In order to facilitate the transfer of patients, universal wheels 132 are provided at the bottom angles of the rectangular base 130, so that medical staff can push the position-changing bed for digestive endoscopy to transfer. For example, there are four universal wheels 132, which are respectively provided at the bottom angles of the rectangular base 130.

[0038] The rectangular bed board 110 is provided with a through hole 112, which can correspond to the position of the leg restraint belt 222, so that the medical staff can fix the leg restraint belt 222. Of course, in other embodiments, the through hole 112 can also correspond to the position of the chest restraint belt 221, so that the medical staff can fix the chest restraint belt 221.

[0039] In some embodiments, a retaining edge 250 is provided on the bottom edge of the bed body 200, and the retaining edge 250 abuts against the edge of the rectangular bed board 110. By providing the retaining edge 250, the retaining edge 250 abuts against the edge of the rectangular bed board 110, thereby preventing the bed body 200 from shifting relative to the rectangular bed board 110, thereby ensuring the stability of the bed body 200.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
