[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a preferred embodiment of the bedridden defecation assistance device for elderly patients of this utility model includes a movable frame 1 with pulleys 11, a lifting platform 2, a lifting mechanism 3, a commode 4, a floating mechanism 5, a support mechanism 7, and a handle 6. The commode 4 is used to receive urine and feces, and the commode 4 is placed on the floating mechanism 5. The floating mechanism 5 is installed on the top surface of the lifting platform 2, and the floating mechanism 5 is used to prevent the commode 4 from sliding on the lifting platform 2 and to allow the commode 4 to float up and down; there are four floating mechanisms 5, of which two floating mechanisms 5 are arranged along the length direction of the lifting platform 2, and the remaining two floating mechanisms 5 are arranged along the width direction of the lifting platform 2, so as to ensure that the commode 4 does not slide on the lifting platform 2; it should be noted that in other embodiments, the number of floating mechanisms 5 can be increased or decreased according to needs, but there are at least two floating mechanisms 5, and at least two of the floating mechanisms 5 are arranged in different directions, that is, the two floating mechanisms 5 are not parallel. The lifting mechanism 3 is mounted on the movable frame 1. The output end of the lifting mechanism 3 is connected to the bottom surface of the lifting platform 2. The lifting mechanism 3 is used to drive the lifting platform 2 to rise and fall. The lifting mechanism 3 is an electric lifting column; however, in other embodiments, a pneumatic lifting column can also be used. The handle 6 is mounted on the movable frame 1 and is used to push the movable frame 1. The support mechanism 7 is mounted on the handle 6 and is used to lift the movable frame 1, suspending the end of the movable frame 1 with the handle 6 in the air. This allows the support mechanism 7 to support the movable frame 1, thereby preventing the movable frame 1 from moving. That is, when the support mechanism 7 extends, the pulley 11 at the end of the movable frame 1 with the handle 6 is suspended in the air, and the movable frame 1 is supported by the support mechanism 7. When the support mechanism 7 retracts, the pulley 11 at the end of the movable frame 1 with the handle 6 directly contacts the ground, allowing the movable frame 1 to slide. In other embodiments, the support mechanism 7 can also be a small electric telescopic rod or other telescopic mechanism.

[0027] The handle 6 is provided with a hook 61, which is used to hang the toilet seat 41.

[0028] like Figure 4 As shown, the movable frame 1 also has a guide rod 12, which guides the lifting platform 2 to rise and fall, ensuring that the lifting platform 2 rises and falls smoothly. The distance between adjacent guide rods 12 in the width direction of the lifting platform 2 is the same as the width of the toilet 4, which can effectively prevent the toilet 4 from tipping over due to large shaking. The lifting platform 2 is provided with a guide hole, and the guide rod 12 passes through the guide hole. The lifting platform 2 is provided with a support lug 21, and the guide hole is located on the support lug 21. The lifting platform 2 is also provided with a baffle 22, which is located at the end of the movable frame 1 away from the handle 6, and the baffle 22 is used to limit the movement of the toilet 4.

[0029] like Figure 5As shown, the bottom surface of the toilet 4 is provided with limiting grooves 42 that are adapted to the floating mechanism 5. That is, there are four limiting grooves 42, two of which are arranged along its width and the other two are arranged along its length. The number of limiting grooves 42 is the same as the number of floating mechanisms 5.

[0030] like Figure 6 As shown, the floating mechanism 5 includes a limiting protrusion 51, a floating rod 52, and a floating spring 53. The limiting protrusion 51 is used to restrict the toilet seat 4. The floating rod 52 is mounted on the limiting protrusion 51 and is typically connected to the limiting protrusion 51 by screws for easy assembly. The floating spring 53 is sleeved on the floating rod 52, with its upper end abutting against the limiting protrusion 51 and its lower end abutting against the lifting platform 2. Each limiting protrusion 51 has at least two corresponding floating rods 52 and floating springs 53 to ensure that the limiting protrusion 51 can be stably supported by the floating springs 53.

[0031] like Figure 7 and Figure 8 As shown, the support mechanism 7 includes a support column 71, a return spring 72, a foot pedal 73, a connector 74, a spring positioning pin 75, a housing 76, and a connecting rod 77. The housing 761 is mounted on the connecting rod 77, which is connected to the handle 6. The support column 71 provides support and is fixed to the connector 74. The connector 74 is slidably disposed within the housing 76, and the support column 71 can extend out of the housing 76 under the push of the connector 74. The return spring 72 is sleeved on the connector 74 and is used to reset the connector 74. It should be noted that the return spring 72 is located within the housing 76. The spring positioning pin 75 is mounted on the housing 76 and is used to keep the connector 74 in a low position, thus keeping the support column 71 in the extended position beyond the housing 76. The foot pedal 73 is connected to the connecting member 74. Stepping on the foot pedal 73 causes the connecting member 74 to move downwards, and then the connecting member 74 causes the support column 71 to extend out of the outer shell 76. At the same time, the spring positioning pin 75 extends to limit the connection member 74. There are two of each of the following: support column 71, return spring 72, connecting member 74, spring positioning pin 75, and outer shell 76. Each outer shell 76 is provided with a corresponding support column 71, return spring 72, connecting member 74, and spring positioning pin 75. The two ends of the foot pedal 73 are connected to the connecting members 74 inside the two outer shells 761. In this way, a single step can support both support columns 71, increasing the stability of the support mechanism 7. It should be noted that when the support column 71 is not extended out of the outer shell 76, the spring positioning pin 75 is always compressed by the connecting member 74.

[0032] The outer casing 76 includes a housing 761 and an end cap 762. The end cap 762 is fixed to the housing 761. The housing 761 is provided with a clearance opening 7611, which is used for the foot pedal 73 to extend into the housing 761 and connect with the connector 74. The end cap 762 is provided with a through hole adapted to the support column 71, so that the support column 71 can pass through the outer casing 76.

[0033] The support column 71 is typically made of a material with anti-slip properties, such as rubber. The support column 71 is connected to the connector 74 via bolts 8. The support column 71 has mounting holes 711, which are countersunk holes. This allows the bolts 8 to be completely submerged within the support column 71, ensuring that the bolts 8 do not affect the manufacturing effect of the support column 71. It also increases the strength of the support column 71, preventing it from bending and reducing its overall height.

[0034] The connector 74 is T-shaped, which allows the upper end of the return spring 72 to abut against the connector 74, and allows the return spring 72 to drive the connector 74 to reset.

[0035] In use, medical staff push the movable frame 1 with handle 6 to move the commode 4 under the bed. Using the restraint of handle 6, the position of the commode 4 is quickly positioned so that it is accurately aligned with the opening on the bed. Then, the foot steps on foot pedal 73 and lifts handle 6 upward, causing foot pedal 73 to press down on connecting piece 74. Connecting piece 74 presses down on support column 71, allowing support column 71 to extend from housing 761. At the same time, spring positioning pin 75 limits connecting piece 74, keeping it stationary and thus keeping support column 71 in the extended state. Releasing handle 6 allows support column 71 to provide support to handle 6, suspending the pulley 11 at the end of movable frame 1 near handle 6. This ensures that movable frame 1 will not move during defecation, preventing leakage.

[0036] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
