Abstract

Multifunctional curved bed has upwards curved surface on its two sides, and axle journels in axle sleeve at its two ends. The bed surface can be rotated while someone turns over in the bed, and while the bed surface is rotated, someone in the bed can turn over easily. It is provided with chair combination, hole to chamber pot, etc. The bed surface shape is determined by considering build type. While someone in the bed turns over, he can stay in any position, which is always lowest position and the gravity center height of the body-bed system is unchanged.

Description

Multifunctional curved bed

The present invention relates to multi-functional life bed and multifunction nursing bed.

The bed surface of prior art is the plane, and the contact surface between plane bed and the human body is less, and the pressure of the bed surface that human body is subjected to is bigger, influences the blood circulation at human body pressurized position, makes the people feel unhappy, need often stand up adjustment.Owing to the ellipse garden of human body, the people stands up on the bed of plane in addition, and when people's body side surface rotated, the gravity center of human body rose, and makes to stand up relatively effort.

The invention is characterized in that bed surface is the curved surface that both sides are bent upwards, there is spindle nose at the two ends of bed surface, and spindle nose is installed in the axle sleeve of bed two end supports, and the people rolls on bed surface when standing up, and bed surface can sway; When rotating bed surface, roll easily under the people can drive at the bed surface of bending and stand up, general as shown in Figure 1 curved bed, for safe in utilization and convenient, curved bed all have a spacing and bed surface locking device of bed surface inclination maximum.Curved bed owing to the bed surface both sides are bent upwards, make that the contact surface between bed surface and the human body increases, the pressure that human body is subjected to bed surface reduces, and helps the blood circulation at human body pressurized position, makes the people sleeping easy, happy.In addition, factors such as the variation of gravity center of human body and bed surface center of gravity and the ellipse garden of human body degree when having considered that owing to the selection definite and the spindle nose position of bed surface curve shape human body rolls on curved bed, it is lighter to make rolling stand up.

The ellipse garden degree of determining to consider human body of bed surface curve shape with the selection of spindle nose position, and the people lies low in the middle process fullness in the epigastrium and abdomen foot row condition of standing up to two side rolls of bed surface: and 1. the people can freely be still in any position of bed surface, and is the bed surface extreme lower position; 2. the height of C.G. of human body and bed surface composition system is constant.1. condition is according to the deflection arm of force decider body weight power of the bed surface center of gravity deflection arm of force at opposite side, the corresponding lateral attitude of the bed surface minimum point of supporting human body when also just having determined a certain angle of bed surface deflection, the lateral attitude of bed surface minimum point during promptly with a certain angle of the balance decision bed surface deflection of the arm of force.2. condition then is the lengthwise position of bed surface minimum point when forming the internal energy same angle of constant decision bed surface deflection of system according to human body and bed surface.

Usually we are according to common people's body characteristics, choose at the bottom of the distance of shaft centers bed surface apart from r, utilize above-mentioned two conditions to calculate the coordinate position of arbitrfary point on the bed surface curve according to human body weight, center of gravity, ellipse garden degree and bed surface center of gravity, weight, and the bed surface curve that draws, the also available geometrograph bed surface curve that draws, curve shape as shown in Figure 2.

For further understanding two above-mentioned conditions, we can analyze the system that human body and bed surface are formed, this system and extraneous contact have only the supporting force that two spindle noses are subjected to and the captivation of the earth, there is a center of gravity in system, no matter how human body rolls, how gravity center of human body and bed surface center of gravity change, and system's center of gravity is subjected to two constant equal and opposite in directions, opposite, the effect power point-blank of direction all the time, and the one, by axle center gravity straight down; The 2nd, by axle center holding power vertically upward, the application of force person of system's internal force has only the people, the people is in the process of firmly rolling to both sides in the middle of the bed surface that lies low, gravity center of human body's deflection system gravity vertical one side, because the rotation of bed surface, bed surface center of gravity deflection system gravity vertical opposite side, and rise along camber line, if keep the height of C.G. of system constant, then the gravity center of human body must suitably descend along bed surface, and the shape of bed surface considers the ellipse garden degree of human body simultaneously, and satisfies human body because in the process that the rolling center of gravity descends on bed surface, all the time in the bed surface minimum point, at this moment, need acting though human body rises in bed surface center of gravity in the process of two side rolls, human body is by the suitable decline of bed surface curve when rolling, be the suitable decline of human body, make human body gravity do merit.In the rollback process, the gravity center of human body rises needs acting, but human body is by the decline of bed surface center of gravity in the rolling process, be that bed surface gravity has been done merit, in whole rolling process, because having satisfied the height of C.G. of system, the shape of bed surface remains unchanged, be that the internal energy of system remains unchanged, the just mutual conversion of bed surface gravitional force and human body gravitional force, internal force institute work is that human body institute work is almost nil all the time in the human body whole process of rolling on bed surface like this, frictional resistance when just overcoming bed surface two ends spindle nose and rotating and the elastic deformation resistance institute work between human body and the bed surface.Such bed surface, the sense of promptly going up a slope in the process that the people rolls on bed surface does not have the descending sense yet, has overcome the ellipse garden degree of human body again, has guaranteed that human body rolls to stand up freely on bed surface, and curved bed to be called free style curved bed such for we.

To the people of certain characteristics of human body, weight and ellipse garden degree, there is certain free style curved bed corresponding with it, at this moment we are exactly the inclination angle locking without bed surface, and human body also can free balance be still in the bed surface optional position, and is extreme lower position.The body weight of actual user, the body weight of center of gravity and ellipse garden degree and design standard, center of gravity and some difference of ellipse garden degree possibility, at this moment human body can balance be still in a left side or the right lower position of bed surface minimum point, the amount of the positive work that human body is done during rolling also has a spot of increase, i.e. some effort a little, but it is much smaller always to overcome the ellipse garden of human body degree effort than the people on the bed of plane, however, in order to overcome this shortcoming, we can carry out counterweight with sandbag increase and decrease sand under bed surface, or carry out counterweight with other method, to adjust bed surface position of centre of gravity and weight, but when general difference is little, do not add adjustment and do not have tangible difference yet, can not influence the curved bed superior function of free style yet.Because human limb can be adjusted gravity center of human body's height flexibly and make centre-of gravity shift become the power that bed surface rotates, so the free style of certain parameter is curved bed to have a scope of application to people's concrete conditions in the establishment of a specific crime.

To free style curved bed we can further understand from the another one angle.According to Fig. 2, if axis deviation O point, more near O ' in addition in addition or the bed surface curve more near being that garden heart r is the garden arc of radius with O, then human body lies low the bed surface centre in the process of two side rolls, the gravitional force of system's center of gravity increases faster, feels that uphill gradient is bigger, and system's gravitional force reduces bigger in the process of rollback, feel that downward grades is bigger, and human body can free immobilized extreme lower position have only the bed surface centre position on bed surface.This curved bed balanced type of crying is curved bed, and this curved bed design generally is not used in adult and bed for children, but can be used for bassinet.If axle center O is more near minimum point C in the middle of the bed surface, the bed surface curve is more approaching to be the garden heart with O, the R radius the garden, even R is near the limiting form plane beyond the garden of radius, then the people lies low, and the gradient is bigger at present to two side rolls in the bed surface centre, even landslide, uphill gradient is bigger during rollback, even can not rollback, stop to roll free immobilized minimum point not on bed surface, thisly curved bedly make non-free style curved bed, non-free style is curved bed must the locking of bed surface inclination angle, possibly can't stop when two side rolls in the middle of the bed surface otherwise the people lies low, the curved bed limiting form of non-free style is the plane nursing bed that the bed surface tiltable can make patient roll to stand up.This nursing bed easily comes down when bed surface inclination patient stands up, and must the special messenger protection, in the present invention's design, do not advocate use so non-free style is curved bed, by above comparison, the understanding that we are more deep the curved bed principle of free style.

Weldering such as curved bed head of a bed support and the general available rectangular steel pipe of bed surface skeleton system, also available other material manufacture, bed surface panel multi-layer forming plate etc. also can be gone up different linings and sponge etc. again.

In order to apply with curved bed, I utilize the curved bed principle invention of free style to design a multi-functional curved bed series, to adapt to the patient of the different state of an illness, the adult of different physical characteristics and child's etc. needs below are illustrated with regard to all multi-functional and advantage emphasis of multifunctional curved nursing bed.

One, multifunctional curved nursing bed

Multifunctional curved nursing bed manufactures and designs for the especial patient that can not oneself stand up, can not leave the bed, defecation can not be taken care of oneself, and uses flat bed to nurse this patient and has following problem: 1, change relatively difficulty of moist bed pad and clothes.2, part such as patients back, buttocks is subjected to weight influences blood circulation, meets moist bed pad and generates decubital ulcer easily.3,, make and clean, pat, massage back and cumbersome the patients back treatment of diseases to patient because patient stands up difficulty.4, defecation inconvenience, especially woman's urine more bothers, and the nursing staff often conscientiously does one and steps on muddle, though multiple difference in functionality is arranged at present, nursing bed in specie not, but multifunctional curved nursing bed of the present invention has his irreplaceable function and superiority.

Owing to multifunctional curved nursing bed is to design for especial patient, the rotation of bed surface needs nursing staff's external force effect such as manual or electronic, be to utilize the active rotation drive patient's of bed surface passive rolling to stand up, so the selection of bed surface curve and spindle nose position can be adopted free style, also can adopt non-free style, but the shortcoming of non-free style bed surface maximum is must use the locking of bed surface inclination angle usually, forget that the locking bed surface will rotate or patient can not lie in the bed surface extreme lower position, and rotate bed surface and patient is rolled stand up relatively effort, so generally be not used, though the curved bed people of free style can freely be still in any position of bed surface, and be extreme lower position, but bed surface inclination angle locking device is also all arranged, can not lock bed surface sometimes.The bed surface inclination angle locks available rim brake as shown in Figure 3, also available other method locking.

The conventional method that bed surface rotates is directly to rotate with hands, because the power that the rotation bed surface needs is very little, human body can freely be still in any position of bed surface again, so do not need what gearing.But for realize nursing staff and patient oneself random shake control, the wushu Keyboard Control, even computer program control, pinion on our the also available spindle nose and the big fan tooth of the link arm on the support, rocking arm, leading screw, reduction gearing, motor and drives such as clutch handle, spring, as shown in Figure 4, also available hydraulic oil cylinder place of lead screw and reduction gearing etc.This device not only can be adjusted the bed surface inclination angle, locks the brake function of bed surface in addition and removes the clutch function that bed surface locks.

Turn over or take off work such as bed pad on when bed pad that accept nursing for the patient that can not stand up is climbed very easily at bed surface, treat, transposing is moist and defecation, the wide surface curve length of bed surface should satisfy general patient and climb at bed surface one lateral edges, when rotating with the bed surface opposite side, under the drive of bed surface, patient can roll easily to stand up and climb to bed surface opposite side edge, be that patient can roll easily under the drive that bed surface rotates and stands up 360 °, generally about 130mm, the bed surface curve is got Fig. 2's to the wide surface curve length of Que Dinging thus Full curve.Patient can stand up 360 ° multifunctional curved nursing bed as shown in Figure 5.

Band is the backrest seat combination that can be adjusted to different angle in the middle of the bed surface of multifunctional curved nursing bed, just hole with cover is arranged as shown in Figure 6 in the middle of the seat.The inclination angle of backrest can be adjusted with hand method with the leading screw of positive left-hand thread half and half, as shown in Figure 7.This method can not only be adjusted inclination of the seat backrest and can also lock backrest and make it to rest on any position, and also available change-speed gearing, the above-mentioned leading screw of driven by motor rotate, even the available hydraulic oil cylinder.Electronic or hydraulic backrest, available wushu keyboard even shake control.The adjustment at pedal inclination angle is to utilize parallelogram principle to make pedal and backrest interlock in the backrest seat combination, drives the identical change at pedal inclination angle by the adjustment of inclination of the seat backrest, on the push-pull bar of interlock bedpan stand is arranged.Patient glides when preventing backrest inclination, and the seat back rake angle is also along with change, and the adjustment of seat back rake angle and pedal interlock adopt eccentric curve cam, and the increase with inclination of the seat backrest before this increases, and is that the increase with inclination of the seat backrest reduces again.The seat hypsokinesis, the interlock principle of pedal and backrest as shown in Figure 8.

Because interconnecting of bed surface that is bent upwards and spindle nose supporting makes bed surface intensity greatly strengthen, so we utilize firm bed surface framework, traction apparatus can be installed, three card bases of the special traction apparatus that only need hang tag during use can use.

Stool handhole cover door can be with the method for downward swing door or decline with armstrong's patent or electric opening, but stool handhole cover door tends to be made dirty below just hole.Because patient must have the nursing staff on the scene when defecation, stand up, remove bed pad, take off underwear, transfer seat etc. to patient, so it is more practical to adopt upward flip to take stool handhole cover door in passing away, the port lid of promptly can not making dirty, structure is simple and practical again.

The function of multifunctional curved nursing bed and advantage.

1, because being bent upwards of bed surface both sides makes the contact area of human body and bed surface increase, and the pressure of the bed surface that health is subjected to reduces, and is of value to the blood circulation at health pressurized position, and the people is felt comfortably cool, this old man to the sick bed of lying for a long time is highly profitable.

2, along with the rotation of bed surface, patient can roll easily in 360 ° of scopes and stand up, greatly facilitate the nursing staff and in time change moist bed pad and clothes for patient, and, also made things convenient for the doctor to the patients back treatment of diseases simultaneously to nursery works such as the scouring of patients back, sidepiece, beating, massages.

3, can be according to the needs of patient comfort, by changing the inclination angle of the curved bed bed surface of free style, at any time change the force part and the bed posture of health, and reach the bed surface extreme lower position, at this moment always both sides are slightly high for patient's sensation, have the sense of stability and the security, the sense of inclination can not arranged owing to the rotation of bed surface.According to this curved bed exceptional function, we can change the bed surface inclination angle with the method for electric remote control, allow patient oneself arbitrarily change the bed posture, adjust the health force part.

4, thermal property is good, because bed surface is the curved surface that both sides are bent upwards, makes that the sealing between bed surface and the lid quilt is better, can not make lid be tilted, drop and catch a cold owing to patient touches simultaneously.

5,0～80 ° of random adjustable comfortable seat in inclination angle, adjustment, very easy to use, especial patient for the sick bed of lying for a long time, often changing seat prone position gesture is their extravagant hope, it also is a kind of enjoyment, the pedal that multifunctional curved nursing bed is comfortable, proper seat and backrest can be realized patient's extravagant hope easily.Proper seat and backrest are that the multifunction nursing bed institute in plane is irrealizable.

6, toilet seat function easy to use feels comfortably cool when allowing patient-sized just, smooth and easy, and also can not make dirty clothes and bedding make concerning the nursing staff that simultaneously connecing dung connects this very difficult work of urine and become easy.Use step: 1. rotate bed surface and allow patient roll to stand up and climb to bed surface one side; 2. turn over or take out bed pad on, take off patient's underwear down, take off stool handhole cover door; 3. turning round bed surface makes patient turn back the center; 4. adjusting the seat function makes patient seated; 5. putting the bedpan patient well can use.

7, flexibly practical table function, being bent upwards of when bed surface is adjusted to seat because bed surface both sides except the handrail that can be used as seat, also can be put one flat plate in the above, constitutes table, and patient can make dining table, also can write, read a book or play chess etc. with the household.

8, many people backrest couch function, it is minimum spacing that the rotation bed surface forwards bed surface one side to, and the locking bed surface can become one can sit the three backrest couch to four-player.

9, the peaceful and comfortable couch function of many people is removed the bed surface locking, and bed surface can freely be rotated around axle, and such couch can become one can sit the three peaceful and comfortable couch to four-player.

10, peaceful and comfortable bed function is removed the bed surface locking, and people's rolling about on the bed surface can cause swinging back and forth of bed surface, and this is a kind of joy and enjoyment to some.

11, safety bed function, the locking bed surface can become prevent to tumble in bed safety bed.

12, ordinary student is applied flexibly a function, and except that above-mentioned specific function, the multifunctional curved bed ordinary student that also can be used as is applied flexibly bed.

13, extension table function, the special traction apparatus that hangs tag can become extension table.

14, because bedstead is a metal structure, bedstead also can weld other miscellaneous function.As 1. active stand for transfusion; 2. gravity traction pulley etc.

Two, general sick bed

For the patient that can oneself stand up or can stand up easily by nursing staff's help, we can reduce multifunctional curved bed width in common plane single bed width, to reduce shared the vacating of bed surface; Can not establish just hole for we of the defecation of can leaving the bed, even do not establish pedal, the also available simple support of backrest, adjust inclination of the seat backrest in several fixed angles, because patient can sit up, do not need complicated mechanical to remove to adjust backrest, the height of head of a bed support also can suitably reduce, and we just can design the free style curved surface sick bed with different specific functions like this.

Three, generally live with bed

The bed surface linear width is near the common plane single bed, and determining with the selection of spindle nose position of bed surface curve is curved bed with free style according to the daily life that common people's body characteristics divides several models to design.

Four, bed for children

Bed surface length, wide surface curve length, the selection of the shape of curve and spindle nose position etc. divide several models and the daily life that designs is curved bed with free style by child's physical trait.

Five, bassinet

Be fit to the curved bed of baby, according to baby's physiological characteristics, do not need the baby to roll and stand up, so adopt balanced type curved bed, the distance of bed surface spindle nose position minimum point in the middle of the bed surface is generally greater than the bed surface radius of curvature, so that bed surface waves under the promotion of external force.

In sum, multifunctional curved nursing bed, general curved surface sick bed is except the functions peculiar that they preserve, other general function and generally life usefulness bed, the child is with curved bed identical, simultaneously all adopted the curved bed principle of free style, all have following identical advantage and function: health is subjected to the pressure of bed surface little; The rolling turning defecation freely; Has the security; Good heat insulating; Many person sofas chair function; The peaceful and comfortable couch function of many people; Peaceful and comfortable bed function; Common with the bed function; Multiple function such as safety bed function.Since above-mentioned all curved bedly all have a multiple function, so we of the present invention curved bed be called multifunctional curved bed, multifunctional curved bedly be in the initial research and development stage now, above-mentioned electronic, hydraulic pressure, manual bed surface inclination angle is adjusted, seat back manually, electronic inclination angle is adjusted, the locking means of bed surface, individual's design that the interlocking method of the interlocking method of backrest and pedal and pedal support and seat hypsokinesis etc. are still initial, along with multifunctional curved bed applying, we collect the wide view of think of, also can design more ingenious rational control method of adjustment, make multifunctional curved bed technology, profile and performance are better rationally.
