Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a sanitary excretion care bed. Background Art

[0002] Nursing beds are generally powered beds, which are divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, so that family members can accompany them. They have multiple nursing functions and operation buttons, and are insulated and safe. They can be used by sick people, severely disabled people, the elderly, and healthy people during hospitalization or home treatment, rehabilitation and recuperation, and come in various sizes and forms. Since many patients have different heights and leg lengths, and the defecation position designed for common nursing beds is mostly fixed, it is more difficult to use nursing beds for some patients who are inconvenient to move.

[0003] There are also many nursing beds that are convenient for excretion in the prior art. For example, the Chinese utility model patent with publication number CN204840020U discloses a nursing bed for clinical obstetrics and gynecology, including a bed body, which is mainly composed of a bed board and bed legs. The bed legs are a lifting hydraulic column structure and are provided with two groups in front and back; one side of one of the bed legs is provided with a vertical sleeve, and the sleeve is connected with a bracket, and the bracket is divided into a horizontal part and a vertical part. The vertical part is arranged in the sleeve, and the end of the horizontal part is provided with a urinal frame for placing a urinal; the middle part of the bed board is a mesh structure and is provided with an excretion port, and the urinal frame for placing the urinal is located below the excretion port. The disadvantage of this patent is that the excretion port is fixed, and there is a lack of measures to adjust the excretion port for patients of different heights, and the nursing bed lacks auxiliary drainage measures for cleaning patients who are inconvenient to move. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a hygienic excretion care bed to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sanitary excretion care bed, comprising a bed support frame, wherein the inner walls on both sides of the bed support frame are fixedly installed with fixed plates, and the inner walls of the bed support frame near the two ends are rotatably connected with a driving shaft and a driven shaft, and the surfaces of the driving shaft and the driven shaft are respectively fixedly sleeved with a driving sprocket and a driven sprocket, and the driving sprocket and the driven sprocket are connected through a transmission chain, and the transmission chain slides on the upper surface of the fixed plate, and a plurality of evenly distributed slats are fixedly installed on the upper surface of the transmission chain, a moving groove is provided in the middle of the upper surface of the fixed plate, and an excretion port is provided in the middle of the slat and near the moving groove, a seat cushion is provided at the excretion port, and a moving device and a cleaning device that slide on the surface of the moving groove are fixedly installed on the lower surface of the transmission chain, and a lifting mechanism is provided between the moving device and the seat cushion.

[0006] In order to utilize the linkage between the No. 1 electric push rod and the No. 2 electric push rod to control the seat cushion to be retracted into the storage groove, so that the exposed excretion port is convenient for the patient to excrete on the nursing bed, the lifting mechanism includes a No. 1 electric push rod fixedly installed on the bottom of the seat cushion, a storage groove is provided on the side of the moving device close to the seat cushion, and a No. 2 electric push rod is fixedly installed on the inner wall of the storage groove, and the side surface of the bottom of the No. 1 electric push rod is fixedly installed on one end of the No. 2 electric push rod passing through the storage groove.

[0007] In order to utilize rollers to reduce the friction force on the moving device and the cleaning device when the transmission chain drives them to move in the moving groove, thereby facilitating their movement and providing support for the transmission chain at the moving groove, rolling grooves are provided at the bottom of the moving device and the cleaning device, and rollers are rotatably connected to the inner walls of the rolling grooves via rotating shafts, and the rollers pass through the rolling grooves and contact the moving grooves.

[0008] In order to utilize the bidirectional drive motor to provide power for the rotation of the driving shaft, so that the driving sprocket on the driving shaft can control the movement of the transmission chain, so that the slats fixedly installed on the transmission chain can move, and thus the discharge port constructed by multiple slats can move, rotation grooves are opened at both ends of the fixed plate, and the driving shaft and the driven shaft are both inserted into the interior of the rotation groove, a bidirectional drive motor is fixedly installed on the inner wall of the rotation groove close to the driving shaft, and the output shaft of the bidirectional drive motor is fixedly connected to the driving shaft.

[0009] In order to collect excrement by means of the collection box, thereby ensuring environmental hygiene, a placement groove is provided in the middle of the movable groove, and the interior of the placement groove is slidably connected with the collection box.

[0010] In order to be able to control the water inlet pipe through the control valve to add clean water for cleaning to the water tank, so that the water tank can provide a water source for the cleaning nozzle, so that the cleaning nozzle can clean the area where the patient excretes, a water tank is opened inside the cleaning device, and a cleaning nozzle connected to the water tank is fixedly installed on one side of the cleaning device, and a water inlet pipe connected to the water tank is fixedly installed on the other side of the cleaning device, and a control valve is fixedly installed on the surface of the water inlet pipe.

[0011] In order to utilize the volume to facilitate the movement of the cushion at the discharge port and the entry of excrement of the patient into the collection box when defecating, the size of the discharge port is slightly larger than the size of the cushion, and smaller than the size of the collection box.

[0012] In order to prevent excrement from splashing when entering the collection box, thereby ensuring the hygiene of the environment around the device, an anti-splash ring is fixedly installed on the top of the collection box.

[0013] In order to facilitate nursing staff to clean up the excrement in time and thus improve the convenience of cleaning, cleaning grooves connected to the moving grooves are provided on both sides of the bed support frame.
