[0002] In daily life and medical care, patients with diarrhea face many inconveniences. Due to the influence of their condition, they may need to collect excrement anytime and anywhere. Therefore, it is of great practical significance to develop a convenient, efficient, and easy-to-use excrement collection device for diarrhea that can adapt to various scenarios and the needs of different patients.

[0003] Current excrement collection devices still have the following shortcomings:

[0004] Traditional methods of excrement collection, such as using a regular toilet, pose significant difficulties for patients with limited mobility, especially those who are bedridden and suffering from diarrhea. They cannot meet the needs of patients anytime and anywhere, and patients may require assistance to move to the toilet. This process is not only labor-intensive but may also lead to accidents due to the patient's physical weakness. Existing temporary excrement collection devices are often limited in function, only able to collect simple excrement and lacking adaptability to the patient's physical condition. For example, they cannot flexibly adjust the height and angle of the collection device according to the patient's height and sitting posture, which can easily lead to excrement leakage and cause great inconvenience to patients and caregivers.

[0005] To address the aforementioned technical problems, this utility model provides a simple excrement collection device for diarrhea, which solves the problem that traditional excrement collection methods mentioned in the background art, such as using ordinary toilets, pose great difficulties for patients with limited mobility, especially bedridden patients with diarrhea, and cannot meet the needs of patients anytime and anywhere.

[0006] The purpose and effectiveness of this utility model, a simple device for collecting excrement for diarrhea, are achieved by the following specific technical means:

[0007] A simple excrement collection device for diarrhea includes: a base plate; the base plate has a rectangular plate structure, and four sets of self-locking casters are arranged in a rectangular array at the bottom of the base plate; a set of U-shaped plate pedal structures are fixedly arranged on both sides of the front end of the base plate; a scissor mechanism is slidably connected to the top of the base plate; a U-shaped plate mounting plate is fixedly arranged on the top of the scissor mechanism; a cylindrical connecting bucket is rotatably arranged on the inner front side of the mounting plate, and a through circular groove structure is opened at the bottom of the connecting bucket.

[0008] Furthermore, a cylinder is fixedly installed on the rear side of the base plate, and the cylinder is connected to the scissor mechanism for transmission; a water tank is fixedly installed on the rear side of the mounting plate.

[0009] Furthermore, four sets of nozzles are fixedly arranged in a ring array on the outer side of the connecting barrel.

[0010] Furthermore, a worm gear is fixedly installed on the outer side of the rotating shaft of the connecting barrel; a worm is rotatably installed on one side of the front end of the mounting plate, and the worm is meshed with the worm gear.

[0011] Furthermore, a storage bucket is fixedly installed on the top of the base plate, and the storage bucket is located at the bottom of the connecting bucket.

[0012] Furthermore, a piston cylinder is fixedly installed in the middle of the front side of the base plate. The piston cylinder adopts an internally hollow cylindrical structure, and a through circular groove structure is opened at the top of the piston cylinder. A one-way valve water inlet structure is opened on the left side of the piston cylinder, and the water inlet of the piston cylinder is connected to the water storage tank through a pipe. A one-way valve water outlet structure is installed at the bottom right side of the piston cylinder, and the water outlet of the piston cylinder is connected to the nozzle through a pipe. A cylindrical sliding rod is slidably installed in the circular groove at the top of the piston cylinder, and a spring is sleeved on the outside of the sliding rod. A piston plate is fixedly installed at the bottom of the sliding rod, and the outer wall of the piston plate is in contact with the inner wall of the piston cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By controlling the operation of the cylinder, the scissor mechanism is raised and lowered, thereby adjusting the height of the connecting bucket to meet the needs of patients of different heights. At the same time, the connecting bucket can be rotated flexibly by the meshing transmission of the worm gear and worm wheel, so that it fits better against the user's buttocks, effectively preventing excrement leakage and greatly improving the adaptability and safety of the device.

[0015] The device is equipped with an automatic cleaning system consisting of a piston cylinder, sliding rod, piston plate, and nozzles. After excretion, the user simply steps down on the sliding rod to force the piston plate to squeeze the water out of the piston cylinder, which is then rinsed through the nozzles. Releasing the sliding rod automatically replenishes the piston cylinder with water, preparing it for the next cleaning cycle. This design eliminates the need for manual cleaning of the connecting tank, significantly reducing the cleaning burden on caregivers and users while ensuring timely and thorough cleaning and minimizing the risk of bacterial growth.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a simple excrement collection device for diarrhea, comprising: a base plate 1; the base plate 1 adopts a rectangular plate structure, and the bottom of the base plate 1 is provided with four sets of self-locking universal wheels in a rectangular array, and a set of U-shaped plate pedal structures are fixedly provided on both sides of the front end of the base plate 1; a scissor mechanism 102 is slidably connected to the top of the base plate 1; a U-shaped plate mounting plate 103 is fixedly provided on the top of the scissor mechanism 102; a cylindrical connecting bucket 105 is rotatably provided on the front inner side of the mounting plate 103, and the bottom of the connecting bucket 105 has a through circular groove structure.

[0027] Four sets of nozzles 106 are fixedly arranged in a ring array on the outer side of the connecting barrel 105.

[0028] Among them, a worm gear 107 is fixedly installed on the outer side of the rotating shaft of the connecting barrel 105; a worm 108 is rotatably installed on one side of the front end of the mounting plate 103, and the worm 108 is meshed with the worm gear 107.

[0029] The base plate 1 has a storage bucket 109 fixedly installed on its top, and the storage bucket 109 is located at the bottom of the connecting bucket 105.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When the user needs to use the device, first adjust the height of the connecting bucket 105 according to their own needs. By controlling the operation of the cylinder 101, the piston rod of the cylinder 101 extends or retracts, thereby driving the scissor mechanism 102 to move up and down. As the scissor mechanism 102 rises and falls, the mounting plate 103 and the connecting bucket 105 mounted on it also rise or fall accordingly. After adjusting the device to a suitable height, the user can control the rotation of the connecting bucket 105 by operating the worm gear 108. By rotating the worm gear 108, due to the meshing transmission between the worm gear 108 and the worm wheel 107, the connecting bucket 105 will rotate around its axis, thereby adjusting the angle of the connecting bucket 105 so that the connecting bucket 105 can better fit the user's buttocks and avoid the leakage of excrement. Then lock the self-locking casters to prevent the device from moving. The user stands in front of the device, puts both feet on the pedal structure, aligns their body with the through groove of the connecting bucket 105, and can then use it.

[0032] Example 2:

[0033] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown:

[0034] A cylinder 101 is fixedly installed on the rear side of the base plate 1, and the cylinder 101 is connected to the scissor mechanism 102 in a transmission manner; a water tank 104 is fixedly installed on the rear side of the mounting plate 103.

[0035] A piston cylinder 110 is fixedly installed in the middle of the front side of the base plate 1. The piston cylinder 110 adopts a hollow cylindrical structure, and a through circular groove structure is opened at the top of the piston cylinder 110. A one-way valve water inlet structure is opened on the left side of the piston cylinder 110, and the water inlet of the piston cylinder 110 is connected to the water storage tank 104 through a pipe. A one-way valve water outlet structure is set at the bottom right side of the piston cylinder 110, and the water outlet of the piston cylinder 110 is connected to the nozzle 106 through a pipe. A cylindrical slide rod 111 is slidably installed in the circular groove at the top of the piston cylinder 110, and a spring is sleeved on the outside of the slide rod 111. A piston plate 112 is fixedly installed at the bottom of the slide rod 111, and the outer wall of the piston plate 112 is in contact with the inner wall of the piston cylinder 110.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In this invention, during the excretion process, the excrement falls directly into the collection bucket 109 through the through groove at the bottom of the connecting bucket 105. The user steps down on the sliding rod 111, which drives the piston plate 112 to move downward inside the piston cylinder 110. Due to the one-way valve inlet structure on the left side of the piston cylinder 110, water cannot flow out from the inlet at this time. The piston plate 112 squeezes the water in the piston cylinder 110 out of the one-way valve outlet at the bottom right side. The water flows through the pipe to the nozzle 106, and the nozzle 106 sprays water into the interior of the connecting bucket 105. The device allows for rinsing without manual cleaning, reducing the cleaning burden. After releasing the slide rod 111, the spring causes the slide rod 111 to move the piston plate 112 upwards to reset. At this time, a negative pressure is formed inside the piston cylinder 110, and the water in the water tank 104 flows into the piston cylinder 110 through the one-way valve inlet, preparing for the next cleaning. Then, the waste in the collection bucket 109 can be emptied and cleaned. This device can meet the temporary defecation needs of diarrhea patients and can also be used by bedridden patients on appropriate convalescent beds. It has multiple uses and better functionality.
