Description

Technical Field

[0001] The present invention relates to the technical field of automatic flushing toilets for nursing beds, and in particular to an automatic flushing toilet cover and working method for a nursing bed. Background Art

[0002] With the increasing aging of the population, the demand for nursing beds is also increasing day by day, which has led to a blowout development of nursing bed products. Nursing beds have gradually entered each family from being only used in medical institutions before.

[0003] Nursing beds are generally for those patients who are inconvenient to move and bedridden for a long time. They need to get out of bed with the help of nursing staff every day for eating and rehabilitation training. Helping patients get in and out of bed manually is not only a heavy burden on nursing staff, but also may cause accidental bumps and strains to patients due to improper force. Nursing beds can better help nursing staff take care of patients in daily life, such as: movable dining tables, table boards and sitting-up functions, etc., which can well help nursing staff look after patients and greatly reduce the burden on nursing staff.

[0004] For patients who are bedridden for a long time and lack the ability to move, how to urinate is a relatively big problem in life. To solve this problem, some toilet structures have been designed in current nursing beds on the market to facilitate urination for long-term bedridden users. For example, CN202011354415.0 discloses an intelligent nursing bed with a toilet that is easy to clean. The intelligent nursing bed includes a bed frame, a bed board, and a toilet located below the bed board. The nursing bed further includes: a central bed board, a toilet base, a toilet sliding mechanism, and a toilet lifting mechanism. The central bed board is located at the waist and hip position of the human body after lying down on the bed board, and includes a left central bed board, a right central bed board, a left central frame, and a right central frame; the toilet sliding mechanism includes a toilet sliding shaft, a linear bearing, and a bearing connecting piece; the toilet lifting mechanism includes a screw rod, a third nut, a third sliding connecting piece, and a linkage lever; wherein the toilet sliding shaft is arranged obliquely along the transverse direction of the bed body.

[0005] However, nursing beds with toilet structures similar to the above only have simple functions to assist urination. It is inconvenient for patients to operate during urination or they need manual assistance. Especially when urinating, because the toilet does not have a splash-proof function, urine is likely to splash everywhere and dirty the beddings, or the liquid splashes during automatic flushing and wets the mattress, making both patients and caregivers feel physically and mentally exhausted. Although there are currently some lifting toilets with baffles, due to their fixed shapes, they cannot block well, and are prone to collide with the legs during lifting, causing skin contusions.

[0006] Therefore, how to design a more user-friendly device that is more convenient for bedridden users to urinate has become one of the technical problems that need to be urgently solved by those skilled in the art. Summary of the Invention

[0007] The object of the present invention is to provide an automatic flushing toilet cover for a nursing bed and a working method thereof.

[0008] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0009] An automatic flushing toilet cover for a nursing bed includes a cover skeleton, which consists of a plurality of skeleton joints arranged in sequence from top to bottom. The left and right sides of the front ends of adjacent two skeleton joints are hinged through skeleton rotating shafts, and the rear ends of adjacent two skeleton joints are hinged to each other through a telescopic device;

[0010] The left and right sides of the front end of the lowermost skeleton joint are hinged to the left and right sides of the middle part of the base through skeleton rotating shafts, and its rear end is hinged to the rear part of the base through a telescopic device;

[0011] Buffer devices are installed on the edges of each skeleton joint and on the edges of the base that will contact the human body.

[0012] Among them, the buffer device is an airbag or a soft cushion block.

[0013] Among them, when the buffer device is an airbag, the airbags on each skeleton joint and the base are each composed of a plurality of air chambers; each air chamber is respectively connected to an air pump through a trachea.

[0014] Among them, when the buffer device is an airbag, a pressure sensor is provided between the edge of the skeleton joint and the buffer device, and between the edge of the base and the buffer device;

[0015] When the buffer device is a soft cushion block, a pressure sensor is provided between the edge of the skeleton joint and the buffer device, and between the edge of the base and the buffer device.

[0016] Among them, the two ends of the telescopic device between adjacent two skeleton joints are respectively hinged to adjacent two skeleton joints; one end of the telescopic device between the lowermost skeleton joint and the base is hinged to the skeleton joint, and the other end is hinged to the base.

[0017] Among them, when all the telescopic devices contract, the whole cover is in an upright state; when all the telescopic devices extend, the whole cover is in a bent state.

[0018] Among them, the telescopic device is a micro electric screw or a telescopic cylinder.

[0019] Among them, the lower part of the base is fixedly connected to the upper part of the automatic flushing toilet; the skeleton joint is made of elastic plastic material; the inner and outer surfaces of the whole cover skeleton are coated with a protective layer, and the protective layer is made of silica gel material or waterproof cloth.

[0020] The working method of the automatic flushing toilet cover described in the present invention is specifically as follows:

[0021] When the automatic flushing toilet is not in use, all telescopic devices extend, and the entire cover is in a bent state. The automatic flushing toilet cover sinks and hides under the bed surface of the nursing bed.

[0022] When the automatic flushing toilet cover rises, the telescopic device shortens, pulling the skeleton joints to make the cover in an upright state, facilitating the lifting and lowering activities between the user's legs. Among them, the middle part of the cover first contacts the user's body, and then the toilet lifting bracket adjusts the angle so that the front part of the cover fits closely with the body. Then the telescopic device extends, driving the skeleton joints to bend, driving the upper part of the cover to bend downward and buckle on the lower abdomen of the human body.

[0023] When the buffer device is an airbag, by inflating and deflating the airbag, the shape of the cover edge is adjusted. The system obtains the pressure of each air chamber through a pressure sensor and adjusts the telescopic device at the corresponding position according to the pressure of each air chamber, thereby changing the bending angle of the corresponding skeleton joint. Finally, the pressure of each air chamber is made equal to ensure that the cover fits closely with the human body.

[0024] When the buffer device is a soft cushion block, the pressure sensor senses the pressure at the cover edge and adjusts the angle of the skeleton joints inside the cover so that the pressure at the cover edge is evenly distributed. Through the extrusion force between the cover and the human body, the soft cushion block deforms, thereby ensuring that the cover fits closely with the human body.

[0025] Compared with the prior art, the outstanding effect of the present invention lies in:

[0026] The automatic flushing toilet cover of the present invention can be used for the automatic flushing toilet on the nursing bed, can be deformed and adjusted according to the body posture of the user, and can effectively avoid the problems that the urine splashes everywhere when the bedridden user urinates and soils the beddings or the liquid splashes and wets the mattress when flushing.

[0027] When the automatic flushing toilet cover is in an upright state, it can avoid the cover hitting the user's body when the automatic flushing toilet is lifted. When the automatic flushing toilet cover is in a bent state, it can keep fitting with the lower abdomen of the user's body to ensure that urine does not splash everywhere during urination.

[0028] Before the automatic flushing toilet cover of the present invention fits with the human body, the cover is in an upright state, which is convenient for moving between the legs during lifting and avoids bruising the user's body. When fitting with the human body, the pressure sensing system at the cover edge can real-time monitor the contact force between the cover edge and the human body, and control the telescopic device inside the cover to adjust and change the shape of the cover, so that the cover fits closely with the body without gaps and the force is evenly equal.

[0029] The following further describes the automatic flushing toilet cover for a nursing bed and its working method according to the present invention in conjunction with the accompanying drawings and specific embodiments. Description of the Drawings

Detailed Embodiment

[0038] As Figures 1-3 shown, an automatic flushing toilet cover for a nursing bed includes a cover skeleton. The cover skeleton is composed of 4 skeleton joints 2 arranged in sequence from top to bottom. The left and right sides of the front ends of adjacent two skeleton joints 2 are hinged through a skeleton rotating shaft 3, and the rear ends of adjacent two skeleton joints 2 are hinged to each other through a telescopic device 4; the left and right sides of the front end of the lowermost skeleton joint 2 are hinged to the left and right sides of the middle part of the base 1 through a skeleton rotating shaft 3, and its rear end is hinged to the rear part of the base 1 through a telescopic device 4.

[0039] According to actual needs, in other beneficial embodiments, the number of skeleton joints can also be increased or decreased.

[0040] Each skeleton joint 2 is composed of an outer guard plate 21 and an inner guard plate 22. The left and right ends of the outer guard plate 21 of the same skeleton joint 2 are connected to the left and right ends of the inner guard plate 22, and the middle parts of the outer guard plate 21 and the inner guard plate 22 are connected by at least one connecting plate 23; both the outer guard plate 21 and the inner guard plate 22 are in the shape of an arc-shaped curved surface. The skeleton joint 2 is made of elastic plastic material (a material similar to cartilage to avoid harming the human body in case of failure).

[0041] Both ends of the telescopic device 4 between two adjacent skeleton joints 2 are respectively hinged to the connecting plates 23 of the two adjacent skeleton joints 2; one end of the telescopic device 4 between the lowermost skeleton joint 2 and the base 1 is hinged to the connecting plate 23 of the skeleton joint 2, and the other end is hinged to the inner surface of the base 1.

[0042] In some beneficial deformation embodiments, the inner guard plate 22 and the connecting plate 23 can also be removed, and only the outer guard plate 21 is retained, and the telescopic device 4 is directly hinged to the outer guard plate 21.

[0043] Buffer devices are installed on the edges of each skeleton joint 2 and on the edges of the base 1 that will contact the human body. Among them, the buffer device is an airbag 6 or a soft cushion block.

[0044] As Figures 4-5 shown, when the buffer device is an airbag 6, the airbags 6 on each skeleton joint 2 and the base 1 are all composed of multiple air chambers; each air chamber is respectively connected to an air pump through a trachea. And pressure sensors are provided between the edge of the skeleton joint 2 and the buffer device, and between the edge of the base 1 and the buffer device, for sensing the pressure when fitting with the human body.

[0045] When the buffer device is a soft cushion block, PVDF pressure sensors are provided between the edge of the skeleton joint 2 and the buffer device, and between the edge of the base 1 and the buffer device.

[0046] When all the telescopic devices 4 are extended, the entire shield is in a bent state, as Figure 4 shown. When all the telescopic devices 4 are contracted, the entire shield is in an upright state, as Figure 5 shown.

[0047] The telescopic device 4 is a telescopic cylinder. In other beneficial embodiments, a micro electric screw can also be selected, or an electric rotating shaft can be installed at the position of the skeleton rotating shaft 3.

[0048] The lower part of the base 1 is fixedly connected to the upper part of the automatic flushing toilet 5.

[0049] The inner and outer surfaces of the entire shield skeleton are covered with a protective layer 7, and the protective layer 7 is made of silica gel material or waterproof cloth, ensuring that the urine of the user will not penetrate through the protective layer into the interior of the shield body and cause damage to the device. The overall effect is as Figure 1as shown

[0050] The working method of the automatic flushing toilet cover is specifically as follows:

[0051] As Figure 6 shown, when the automatic flushing toilet 5 is not in use, all telescopic devices extend, and the entire cover is in a bent state. The automatic flushing toilet cover 8 sinks and hides under the bed surface of the nursing bed, saving space.

[0052] When the automatic flushing toilet cover 8 rises, the telescopic device shortens, pulling the skeleton joints to make the cover in an upright state, facilitating lifting and lowering activities in the narrow gap between the user's legs and avoiding bruising the user's body. Among them, the middle part of the cover ( Figure 5 area B in) first contacts the user's body, and then the toilet lifting bracket adjusts the angle so that the front part of the cover ( Figure 5 area C in) fits closely with the body; then the telescopic device extends, driving the skeleton joints to bend, driving the upper part of the cover ( Figure 5 area A in) to bend downward and buckle on the lower abdomen of the human body.

[0053] When the buffer device is an airbag, by inflating and deflating the airbag, the shape of the cover edge is adjusted, and the cover is closely attached to the human body through the inflation of the airbag. Specifically, the system obtains the pressure of each air chamber through a pressure sensor, calculates and compares according to the pressure of each air chamber, adjusts the telescopic device at the corresponding position, thereby changing the bending angle of the corresponding skeleton joint; for the air chamber with low pressure, the air pump inflates the air chamber, or increases the bending angle of the corresponding skeleton joint; for the air chamber with high pressure, the air chamber deflates or straightens the curvature of the corresponding skeleton joint. Finally, the pressure of each air chamber is made equal to ensure that the cover is closely attached to the human body, as Figure 7 shown.

[0054] When the buffer device is a soft cushion block, the pressure sensor senses the pressure at the cover edge and adjusts the angle of the skeleton joints inside the cover to make the pressure at the cover edge evenly distributed. Through the extrusion force between the cover and the human body, the soft cushion block deforms, thereby ensuring that the cover is closely attached to the human body.

[0055] The above-described embodiments are only used to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
