[0001] The utility model relates to the technical field of bedpans, in particular to an automatic bedpan device for a nursing bed. Background Technique

[0002] A nursing bed is a hospital bed designed for patients with limited mobility during home care, aiming to provide a comfortable nursing environment, facilitate the work of nursing staff, and improve the self-care ability of patients. Currently, to facilitate the patient's defecation and excretion, a square hole is designed on the bed board under the patient's buttocks to facilitate the placement of the bedpan. Based on the above, the inventor found the following problems: The current bedpan of the nursing bed is not convenient for flushing the patient's buttocks and anus after excretion, resulting in the need for nursing staff to push the patient to turn over to clean the buttocks and anus, thus reducing the practicality of the bedpan.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic bedpan device for a nursing bed is provided, in order to achieve the purpose of having more practical value. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic bedpan device for a nursing bed to solve the problems raised in the above background technique.

[0005] In view of the above problems, the technical solution proposed by the utility model is:

[0006] An automatic bedpan device for a nursing bed includes a lifting mechanism. The lifting mechanism includes a bottom plate. On both sides of the upper end of the bottom plate, a pair of first hollow cylinders and a pair of second hollow cylinders are respectively connected. Inside a pair of the first hollow cylinders and a pair of the second hollow cylinders, T-shaped rods are slidably arranged. The upper ends of several T-shaped rods are all connected with a support plate. A flushing mechanism is arranged between several support plates. The flushing mechanism includes a connecting seat. The four corners of the connecting seat are respectively connected with the support plates, and an excretion port is opened on the upper end surface of the connecting seat. A round hole is opened at the center of the back surface of the connecting seat. Inside the round hole, a flushing pipe is slidably connected. One end of the flushing pipe far away from the inside of the connecting seat is communicated with a hose. On one side of the outer wall of the connecting seat, a water storage mechanism is arranged. The water storage mechanism includes a water bucket. At the bottom end inside the water bucket, a micro pump is arranged. The water outlet end of the micro pump penetrates through the water bucket and is connected with one end of the hose far away from the flushing pipe. A excrement storage box is arranged at the bottom end of the connecting seat.

[0007] Furthermore, on both sides of the inner wall of the round hole, sliders are arranged. On both sides of the outer wall of the flushing pipe, sliding grooves are opened. One end of the slider far away from the inner wall of the round hole extends into the inside of the sliding groove and is in clearance fit with the sliding groove. And several flushing holes are opened on the top surface of the flushing pipe.

[0008] The beneficial effects of adopting the above further solution are as follows. Through the setting of the slider and the chute, it is convenient for the flushing pipe to move stably within the round hole. When the flushing pipe is pushed into the connecting seat, the side of the slider located outside the connecting seat fits against the inner wall of the chute close to the hose. When the flushing pipe is pulled outwards, the side of the slider located inside the connecting seat fits against the inner wall of the chute away from the hose. By setting the flushing holes, it is convenient for the water in the flushing pipe to spray out through the flushing holes, thereby flushing the patient's buttocks and anus.

[0009] Further, a water inlet pipe is provided at the upper end of the water bucket. A first electromagnetic valve is sleeved outside the water inlet pipe. An electric heating pipe is provided inside the water bucket, and a temperature sensor is provided on one side of the inner wall of the water bucket near the bottom end.

[0010] The beneficial effects of adopting the above further solution are as follows. Through the combined use of the water inlet pipe and the first electromagnetic valve, when the first electromagnetic valve is opened, it is convenient to add water into the water bucket through the water inlet pipe. By setting the electric heating pipe and the temperature sensor, the electric heating pipe is electrically connected to the temperature sensor through a controller. When the temperature sensor detects that the water temperature inside the water bucket reaches the set temperature, it transmits a signal to the controller, and the controller controls the electric heating pipe to stop heating. Further, an opening is provided on the bottom surface of the connecting seat. A shielding mechanism is provided inside the opening. The shielding mechanism includes a pair of shielding plates. The front and back of the pair of shielding plates are respectively connected with a first rotating shaft and a second rotating shaft. The ends of the first rotating shaft and the second rotating shaft away from the shielding plates are both connected to the inner wall of the connecting seat at the opening through bearings. A pair of first micro-motors are provided on the front surface of the connecting seat. The output ends of the pair of first micro-motors are both in transmission connection with the first rotating shaft.

[0011] The beneficial effects of adopting the above further solution are as follows. By setting a pair of first micro-motors, the rotation directions of the output ends of the pair of first micro-motors are opposite. When the pair of first micro-motors are started, they drive the pair of first rotating shafts, making the pair of first rotating shafts rotate in opposite directions, so that the pair of shielding plates rotate to a vertically upward state, connecting the connecting seat and the excrement storage box, and thus facilitating subsequent excretion. After excretion is completed, the pair of shielding plates are restored to their original positions by the pair of first micro-motors, separating the connecting seat and the excrement storage box into two spaces. Further, a drain pipe is connected to the right side of the outer wall of the connecting seat. A second electromagnetic valve is sleeved outside the drain pipe.

[0012] The beneficial effect of adopting the above further solution is that through the combined use of the drain pipe and the second solenoid valve, when the second solenoid valve is opened, it is convenient to discharge the flushing wastewater in the communication seat through the drain pipe after excretion. Further, the outer walls of a pair of the second hollow cylinders are connected with mounting boxes, and one side of the outer walls of a pair of the T-shaped rods is connected with racks. A rotating rod is arranged inside the mounting box. Both ends of the rotating rod are connected with the two sides of the inner wall of the mounting box through bearings, and gears are sleeved outside the rotating rod near a pair of the racks. The gears are meshed with the racks. A first motor is arranged on the front surface of the mounting box, and the output end of the first motor is in transmission connection with the rotating rod.

[0013] The beneficial effect of adopting the above further solution is that by setting the first motor, when the first motor is started, it is convenient to drive the rotating rod to rotate, so that a pair of gears rotate. Since the gears are meshed with the racks, the racks are driven to move upward, so that the T-shaped rods in a pair of the second hollow cylinders move upward, and under the connection action of the support plate and the communication seat, the T-shaped rods in a pair of the first hollow cylinders move upward. Square grooves are formed in the upper end surfaces of a pair of the second hollow cylinders directly above the racks, and the square grooves are in clearance fit with the racks, so that it is convenient for the racks to pass through the square grooves during the upward movement.

[0014] Further, first threaded grooves are formed in the front and back surfaces of the excrement storage box, and second threaded grooves are formed in the front and back surfaces of the communication seat near the first threaded grooves. Bolts are threadedly connected between the first threaded grooves and the second threaded grooves.

[0015] The beneficial effect of adopting the above further solution is that through the combined use of the first threaded grooves, the second threaded grooves and the bolts, when the bolts are removed, it is convenient to remove the excrement storage box from below the communication seat.

[0016] Further, universal wheels are arranged at the four corners of the bottom end of the bottom plate, and brake pads are arranged on several of the universal wheels.

[0017] The beneficial effect of adopting the above further solution is that by setting the universal wheels, it is convenient to move the automatic toilet device.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the automatic bedpan device of the nursing bed, through the combined use of the lifting mechanism and the support plate, the connecting seat is connected to the lifting mechanism through the support plate, which facilitates the up and down movement of the connecting seat and the excrement storage box. When the connecting seat moves upward and fits with the patient's buttocks, it is convenient for the patient to excrete. By providing round holes, since a flushing tube is slidably arranged inside the round holes, when flushing is required, the flushing tube in the round hole is pushed into the connecting seat. By providing a water bucket, the water required for flushing is stored inside the water bucket. By starting the micro pump, it is convenient to transport the water in the water bucket to the inside of the flushing tube through the hose and spray it out through the flushing holes, so as to flush the patient's buttocks and anus. When excretion is required, the flushing tube is pulled outwards so that the flushing tube is no longer located below the patient's buttocks and anus, avoiding affecting the patient's excretion. By providing an excrement storage box, it is convenient to collect the patient's excrement. BRIEF DESCRIPTION OF THE DRAWINGS
