Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a nursing bed suitable for use by a sick person who needs nursing in the long term.
[0002]
[Prior art]
For some time, sick people with medium winds, brain diseases, central nerve injuries and vegetable conditions require long-term nursing care, and the sick people themselves have no behavioral abilities. Therefore, you must lie on the bed for a long time. However, if the sick person lies on the bed for a long time, the bed is very easy to slip. Thus, once a bed sickness is caused, it is very difficult to repair, and it gives great pain to the sick person and places a great burden on the nurse.
[0003]
For this reason, a sick person who does not have the ability to act has to lie on the bed for a long time. Therefore, the design of the hospital bed has a great influence on the comfort of the sick and the convenience of operation of the nurse. Since it is a sick person who does not have the ability to act, the incidence rate of bedsores is larger than that of a general sick person, and the nursing is more difficult than general and the physical strength is considerably consumed. Therefore, it goes without saying that a bed for general use is not suitable for these sick people. Therefore, it is necessary to use a special hospital bed with a special design.
[0004]
The biggest cause of bed slipping is that the sickbed and the sick person's skin are kept pressed for a long time, resulting in skin ulcers due to poor blood circulation, poor ventilation, and sultry conditions. However, until now, there is no appropriate dedicated bed, so nurses who care for the sick must always massage the sick's skin and promote blood circulation on a regular basis. Thus, although the majority of sick people are nursed, the incidence of bed sores and skin diseases remains high in the long term.
[0005]
In addition to this, it is convenient to give the sick person a sitting state or help to turn over, etc. to give food or drugs, and also to provide convenience for nursing such as bathing, changing clothes, etc. Convenience should be given to nursing such as bathing and changing clothes. There are currently many electric beds, and floor frames are installed to lift or turn the sick person's body. Then, using a motor or a hydraulic device, the bed of the sick bed is driven so that the nurse lifts or turns the sick person, and the physical strength consumed by the nurse is increased. However, a general electric hospital bed has an independent motor for each operation for the required many operations of the floor frame, which must be used to drive the drive mechanism. For this reason, it is necessary to use multiple sets of driving devices at the same time for one functionally complicated electric hospital bed. Therefore, the cost of the electric bed is very high, and it is not possible to bear such a high-cost electric bed in general and low income households.
[0006]
Due to the above-mentioned causes, the conventional beds provided for the sick who have to lie down for a long time cannot effectively solve the cause of bed slip. And the cost is high, and it cannot be borne by ordinary hospitals and households. For this reason, it is impossible to effectively improve the pain of a sick person who is lying on a long-term basis, and the purpose for the convenience of nursing cannot be enhanced. Therefore, it goes without saying that improvement is required.
[0007]
In view of the above situation, the present inventor has actively researched after searching for pains, added experience engaged in the research and development of multi-year correlation products, and finally led to the present invention through experimentation and improvement without notice. Is.

As shown in FIG. 1, the first embodiment of the present invention includes a floor base 10 and an upper part of the floor base 10, in which the upper body of a sick person is raised to sit down, and the lower body is A movable floor frame 30 that can change the contact position between the sick person's body and the floor by being able to move up and down, and the same part of the sick person's body from the pressure on the floor for a long time, and the sick person And a reversal frame 40 of the set used for turning over. As shown in FIG. 2, the present invention further includes a first linkage 50 used to drive the floor frame 20 below the floor frame 20 and the movable floor frame 30, and a first linkage 50 used to drive the movable floor frame. Two linkages 60, the first linkage 50 and a power unit 70 used to drive the two linkages 60, a reversing mechanism 80 used to drive the reversing frame 40 used to turn over the sick, and the reversing frame 40. And two sets of striking mechanisms 90 that are used to generate a rapid, narrow striking motion to massage the sick person's body and promote blood circulation.
[0011]
The nursing bed of the present invention can raise the sick person to the sitting state with the help of the floor frame 20 and can turn the sick person's body to the left or right side using the inversion frame 40. Therefore, when a nurse gives food or a drug to a sick person, or when nursing such as changing clothes or bathing, the physical wear of the nurse is greatly reduced, and the nursing operation is convenient.
[0012]
As shown in FIGS. 2 and 4, the floor frame 20 is a bendable frame, and the position corresponding to the upper body part of the sick is the upper movable part 21 that lifts upward, and the central position is the fixed part 22 that corresponds to the lower body. A site | part is the lower movable part 23 which lifts a leg part of a sick person upward. The upper movable portion 21 and the lower movable portion 23 are connected to the first linkage 50 and can be lifted upward by driving the first linkage 50. Thereby, the upper body of the sick person's body is in a sitting state, and the knee portion is bent upward.
[0013]
As shown in FIG. 4, the first linkage 50 has a front rocker arm 51 that is pivotally mounted on the front rotary shaft 71 and can rotate in conjunction with the front rotary shaft 71. There is a link 52, which is connected between the upper movable part 21 of the floor frame 20 and the front rocker arm 51, and there is a rear rocker arm 53, which is installed on the rear rotating shaft 72. A transmission rod 54 is connected between the rear rocker arm 53 and the lower movable portion 23. At the same time, a transmission rod 55 is connected between the front rocker arm 51 and the rear rocker arm 53. As a result, the rear rocker arm 53 can rotate in conjunction with the front rocker arm 51.
[0014]
As shown in FIGS. 2 and 3, the floor frame 20 is a frame body, and a small number of support bars 24 are installed in its lateral direction, and are used to support the weight of the body of the sick. The movable floor frame 30 is installed below the floor frame 20 and can move up and down. The movable floor frame 30 is provided with a small number of contact bars 31, which move upward in accordance with the movable floor frame 30, protrude from the gaps between the support bars 24, and The frame 20 protrudes above the support bar 24.
[0015]
When the nursing bed of the present invention is used, a ventilation cushion is laid on the floor frame 20 so that the sick person lies comfortably. When the movable floor frame 30 does not operate, the weight of the sick person's body is supported by the support bar 24. Thus, when the contact bar 31 protrudes upward, the position of the pressure received by the sick person's body is switched from the support bar 24 to contact the contact bar 31. Therefore, the pressure of the skin being pressed by the support bar 24 is reduced. Therefore, by moving the movable floor frame 30 up and down, the position of contact between the body of the sick and the floor can be changed without interruption, the same part is not subjected to pressure for a long time, blood circulation is poor, skin It can be avoided from generating ulcers.
[0016]
As shown in FIG. 3, the movable floor frame 30 moves up and down by driving the second linkage 60. The second linkage 60 has a front rocker arm 61 and a rear rocker arm 63, which are pivotally connected to the front rotating shaft 71 and the rear rotating shaft 72, respectively. A link 62 is connected between the front rocker arm 61 and the movable floor frame 30. A link 64 is connected between the rear rocker arm 63 and the movable floor frame 30. When the front and rear rocker arms 61 and 63 swing upward, the links 62 and 64 can push the movable floor frame 30 to move upward. The front rocker arm 61 is driven by the front rotary shaft 71 to rotate. A transmission rod 65 is connected between the front rocker arm 61 and the rear rocker arm 63. Accordingly, the rear rocker arm 63 can rotate in conjunction with the front rocker arm 61.
[0017]
One of the main features of the present invention is that the first linkage 50 and the second linkage 60 can be driven by the same power unit 70. Therefore, the structure of the nursing bed of the present invention can be simplified and the effect of cost reduction can be achieved.
[0018]
As shown in FIG. 5, the first and second linkages 50, 60 of the present invention are both attached to the front rotating shaft 71. A drive arm 73 is welded to the front rotary shaft 71. The end of the drive arm 73 is connected to the power unit 70. The power unit 70 is a drive unit such as a hydraulic cylinder or a linear motor. The power unit 70 has a telescopic rod 74, the end of which is pivotally connected to the drive arm 73. Therefore, when the telescopic rod 74 is expanded and contracted, the drive arm 73 can be driven and swung. As a result, the front rotary shaft 71 can be interlocked to generate a rotating operation, and the front rocker arms 51 and 61 can be interlocked and swung. Thus, the floor frame 20 and the movable floor frame 30 can generate an action.
[0019]
However, the operation strokes of the floor frame 20 and the movable floor frame 30 are completely the same. And when the floor frame 20 is operating, the movable floor frame 30 must be stationary. Further, when the movable floor frame 30 is in operation, the floor frame 20 must be stationary. For this reason, when the front rotating shaft 71 drives the first linkage 50, the second linkage 60 must always remain stationary. Thus, when the second linkage 60 is being driven, the first linkage 50 must be held at a position before operation.
[0020]
The method for achieving the above operation is such that the front rotating shaft 71 transmits the front rocker arm 51 of the first linkage 50 and the front rocker arm 61 of the second linkage 60 in an intermittent transmission system. . Therefore, when the front rotary shaft 71 rotates within a specific angle range, the front rocker arm 51 can be rotated in conjunction with the front rocker arm 61 of the second linkage 60 in a stationary state. Can be held. Thus, when the front rotating shaft 71 rotates within a range of another specific angle, the front rocker arm 61 of the second linkage 60 can be rotated contrary to the above, and the first linkage can be rotated. The 50 front rocker arms 51 can be held stationary. Thus, the present invention allows the first and second linkages 50, 60 to be interlocked with a single power unit 70, and the first and second linkages 50, 60 completely reduce the stroke and time of the operation that occurs. Can get unequally.
[0021]
As shown in FIG. 5, the intermittent transmission structure adopted by the present invention has an intermittent transmission device 511 at the connection position of the front rocker arm 51 and the front rotary shaft 71 of the first linkage 50. In addition, an intermittent transmission device 611 is separately installed at the connecting position of the front rocker arm 61 and the front rotary shaft 71 of the second linkage 60. Sliding tanks 512 and 612 are installed in the intermittent transmission device 511 and the intermittent transmission device 611, respectively. A projecting key 711 is installed on the front rotating shaft 71. The protruding key 711 is inserted into the sliding tank 512 and the sliding tank 612, and can slide within the sliding tank 512 and the sliding tank 612. When the protruding key 711 rotates and comes to a position where both sides of the sliding tank 512 and the sliding tank 612 come into contact with each other, the sliding locker 512 and both sides of the sliding tank 612 are fitted to each other, and the front locker The arm 51 or the front rocker arm 61 can be rotated in conjunction.
[0022]
At the same time, according to the present invention, the sliding tank 512 and the sliding tank 612 are installed at the positions of the same angle. When the front rotating shaft 71 rotates forward, the projecting key 711 is engaged with the side of the sliding tank 512 to drive and rotate the front rocker arm 51. At this time, the protruding key 711 slides in the sliding tank 612 of the intermittent transmission device 611. Therefore, the front rocker arm 61 of the second linkage 60 can be kept stationary. Thus, when the front rotating shaft 71 rotates in the opposite direction, the projecting key 711 changes and engages with the sliding bath 612 and slides in the sliding bath 512. Accordingly, the front rocker arm 61 is interlocked and swings backward. Further, the front rocker arm 51 can be held in the position before the operation.
[0023]
  As shown in FIGS. 6 and 7, the reversal frame 40 includes a left frame 41 and a right frame 42. Left side frame 41orThe right side frame 42 has rotating shafts 411, 4 respectively.21It has. And the rotating shafts 411, 421There are some rods 412 and 422 parallel to each other. The bar bodies 412 and 422 can protrude from the gap between the support bar 24 and the contact bar 31. Thus, the rotating shafts 411, 421Is rotated by being driven by the reversing mechanism 80, so that the rods 412 and 422 can be lifted upward. Thus, the body of the sick is on the leftorCan turn to the right.
[0024]
A conventional electric bed reversing mechanism always uses two sets of driving devices to drive two sets of reversing frames. Thus, the present invention has a structure in which the left and right frames 41 and 42 are driven by a single driving device.
[0025]
As shown in FIG. 7, the reversing mechanism 80 of the present invention has rocker arms 81 and 82, which are attached to the outer sides of the rotating shafts 411 and 421, respectively. And followers 83 and 84, which are respectively mounted below the rotary shafts 411 and 421. When both the followers 83 and 84 are substantially L-shaped, the outside is applied to the inner side surfaces of the both rocker arms 81 and 82, and the rocker arms 81 and 82 swing inwardly, The followers 83 and 84 are driven to generate a swing, so that the rotary shafts 411 and 421 can be rotated in conjunction with each other. There is also a connecting rod 85 which is pivoted at the bottom end of the rocker arms 81 and 82. The drive device 86, which is a drive mechanism such as a hydraulic cylinder or a linear motor, has a telescopic rod 87, and its end is connected to the center of the connecting rod 85. Therefore, the connecting rod 85 can move left and right under the drive of the driving device 86.
[0026]
The followers 83, 84 and the rocker arms 81, 82 are not fixedly coupled, but use the swing of the rocker arms 81, 82 to make contact with the contact surfaces of the followers 83, 84. 84, when the rocker arms 81 and 82 swing, one of the followers 83 and 84 is pushed by the rocker arms 81 and 82. The other one is separated from the rocker arms 81 and 82 so as to maintain an immobile state.
[0027]
As shown in FIG. 7, when the telescopic rod 87 is extended, the connecting rod 85 is pushed leftward, and the rocker arms 81 and 82 are interlocked and swung leftward. At this time, the follower 84 below the right frame 42 is pushed by the rocker arm 82 and swings, so that the right frame 42 is lifted upward. Thus, the follower 83 below the left side frame 41 is separated from the rocker arm 81, and the left side frame 41 can remain stationary. On the other hand, as shown in FIG. 8, when the telescopic rod 87 of the drive device 86 is shortened, the rocker arms 81 and 82 are interlocked and swing rightward, so that the left frame 41 is driven. Lift upwards. Thus, the right frame 42 remains in an immobile state.
[0028]
In the present invention, the reversing mechanism 80 can cause an operation of lifting one of the left frame 41 or the right frame 42 in the reversing floor frame 40 upward. Thus, the sick person's body can be turned to the left or to the right to help the nurse turn the sick person over.
[0029]
In addition, the left side frame 41 and the right side frame 42 can be driven by the hammering mechanism 90 and can generate a quick and small swing. As a result, the body of the sick person can be tapped lightly, the body of the sick person can be achieved, the blood circulation of the skin can be promoted, and the occurrence of skin atrophy can be avoided. . As shown in FIG. 9, the hitting mechanism has a columnar body 91 that is installed vertically and downward below the rotating shafts 411 and 421. There is a motor 92 and a cam 93. The motor 92 and the cam 93 are installed at the shaft center of the motor 92, rotate in conjunction with the motor 92, and maintain contact with the side surface of the columnar body 91. And a follower 94, which is attached to the end of the columnar body 91 and used to contact the cam 93. Therefore, as shown in FIG. 10, when the cam 93 rotates, the columnar body 91 can be swung back and forth within a specific range. As a result, the left frame 41 or the right frame 42 can swing slightly, and the body of the sick can be massaged.
[0030]
The power unit 70, the reversing mechanism 80, and the hitting mechanism 90 of the present invention can be controlled by an electric control circuit (not shown). Moreover, the sick person can be turned over or the body can be lifted by a manual operation method. Further, the operation sequence is set in advance in the electric control circuit to control the floor frame 20, the movable floor frame 30, the reversal frame 40, and the hammering mechanism 90 to be sequentially operated at regular times. Can do. Accordingly, the nursing bed of the present invention can automatically reverse the body of the sick person, change the contact position between the floor and the sick person's body, and perform operations such as the massage of the sick person's body. Therefore, generation | occurrence | production of bed slipping of a sick person can be prevented, the circulation of blood can be accelerated | stimulated, and the condition of flesh atrophy can be reduced.
[0031]
As shown in FIG. 11, in the second embodiment of the present invention, the hitting mechanism 90A used is separated from the reversing frame 40. Among them, there are a large number of left-handed sticks 91A and right-handed sticks 92A, which are connected to a left rotating shaft 93A and a right rotating shaft 94A, respectively. In addition, each of the left strike rod 91A and the right strike rod 92A can be installed in a gap between the support rod 24, the contact rod 31, and the rod bodies 411, 422 of the left and right frames 41, 42. When the left and right rotation shafts 93A and 94A are rotated, the left and right striking rods are lifted upward in conjunction with each other, and a motion of hitting the sick person's body can be generated. Columnar bodies 95A are installed below the left and right rotating shafts 93A and 94A, respectively. A contact ring 98A is attached to the end of the columnar body 95A. And two drive motors 96A, each of which has a cam 97A on its axis. The cam 97A is in contact with the contact wheel 98A. Therefore, the left and right rotating shafts 93A and 94A can be driven and rotated.
[0032]
As shown in FIG. 11, the striking mechanism 90A of the second embodiment of the present invention has independent left and right striking bars 91A and 92A, so that the operations of the left and right striking bars 91A and 92A are as follows. The operation of the reversal frame 40 can be separated. Therefore, after the sick person's body is turned over by the reversal frame 40, the left and right strike bars 91A and 92A can be used to strike the sick person's body.
