Description

  The present invention relates to a care bed suitable for use by general care recipients, persons with severe disabilities such as lower body paralysis, bedridden elderly people, etc., and may be used particularly in hospitals and care facilities, and in general households. In addition, the present invention relates to a care bed apparatus using a mat that is suitable for use in a care bed that can be widely used and can reduce the physical burden on a caregiver during bathing or defecation.

  Conventionally, for hospitalized patients who can take a bath by themselves, as a measure to temporarily become in need of nursing care, the caregiver should be urgently evacuated and put the patient in the bathtub at the hospital. Has been done. However, if the caregiver is bathed by a person who is permanently unable to take a bath, such as a disabled person or a bedridden elderly person, the caregiver will be burdened by holding the caregiver in the bathtub. There was a problem that is large.

  In addition, a care recipient is placed on a stretcher, and the care receiver is placed in a bathtub by taking it down from the stretcher or from the stretcher. In this case, since the stretcher is a joint work of a plurality of caregivers, the burden on the caregivers is reduced as compared to the case of holding them. However, from the viewpoint of the care service operator, there is a problem that multiple caregivers are required for one care recipient, and the burden of care costs increases, and the frequency of bathing is, for example, once or twice a week. As such, there was a problem that it was unavoidable. In addition, the cared person himself has a problem that he / she feels uneasy about whether or not he / she may slide down each time he / she moves from the bed to the bathtub or from the bathtub to the bed.

  Therefore, the bedside of the caregiver (bed surface) of the bed should be able to be lowered via a hammock type or power mechanism, and the bed surface should be lowered while the caregiver is laid down in the bathtub installed at the bottom of the bed There is known a bed apparatus for nursing care that is immersed in the skin (Patent Document 1).

  However, in the care bed device that descends the bed surface and immerses it in the bathtub installed at the bottom of the bed, it takes a lot of work time to work slowly with the consent of the care recipient, In many cases, the care recipient is forced to move for the convenience of the caregiver. Then, there existed a subject that there existed a possibility of making a care receiver have discomfort and fear. Even on the caregiver side, the bed surface is moved up and down by about 50 centimeters while supporting the weight of the cared person, so skill is required for the operation work, and there is a problem that it is difficult to handle it by amateur caregivers and elderly households. It was. Therefore, if sufficient facilities are provided so that it can be easily used by an amateur caregiver or elderly household, there is a problem that the cost increases.

  Therefore, as a method for not moving the caregiver lying on the bed, a form in which the bathtub is moved to the bed with an electric lift or a jack mechanism is also known (Patent Document 2). However, the method of moving the bathtub to the bed using the power mechanism requires a large-scale mechanical facility, and there is a problem that it is not practical to use in a normal home because the burden of maintenance work is large.

Furthermore, as a technique that does not move the lying surface of the care recipient of the bed and does not move the bathtub to the bed, a bag-like sheet is placed on the bed, and the wall surface of this sheet is moved up and down. The thing which is supported by etc. and forms a bathtub temporarily is proposed (patent document 3). However, with a waterproof sheet placed on the bed surface, it is necessary to move the patient from the bed once, and there is a problem that the care work for that is a burden. Moreover, the method of laying a waterproof sheet on the floor surface has a problem that it is difficult to process the toilet.
JP-A-6-343673 Registered Utility Model No. 3063780 Japanese Patent Laid-Open No. 10-24083

  The present invention has been made in view of the above circumstances, and it is not necessary to move the bathtub to the bed, and it is possible to easily take a bath without moving the lying surface of the person being cared for on the bed, and to the caregiver. The purpose is to provide a nursing bed that can greatly reduce the burden on the child. In particular, for the skin of the user lying on the bed surface, the bed surface shape according to the body shape makes the bed comfortable, and even in bedridden conditions such as lower body paralysis, care that can prevent bed slippage The purpose is to provide a bed.

  In order to achieve the above object, the nursing bed according to the present invention has a substantially circular, substantially elliptical, substantially annular, saddle-like or dome shape with respect to the bed frame 10 as shown in FIG. The rod-shaped mat member 20 is a single layer, and a plurality of the bar-shaped mat members 20 are arranged side by side to form a bed surface, and sewage and defecation can be discharged downward from a gap formed between the mat member 20 and the adjacent mat member 20. The mat member 20 includes a mat member 20 having a surface layer portion 21 in contact with a user made of a waterproof member having a deformability enough to form a depression corresponding to a load applied by the user. It is characterized in that the rigidity of the member 20 is configured so that the user does not feel the amount of deflection substantially depending on the load of the user.

  According to the nursing bed having such a configuration, the surface layer portion 21 is composed of a waterproof member having a deformability enough to form a depression corresponding to a load applied by the user. A bed surface shape corresponding to the skin distribution shape of the user lying on the side is obtained. Further, even if the user turns over and the load distribution changes, the shape of the depression is deformed in an adaptive state by the deformation function of the surface layer portion 21, and the sleeping comfort is improved. Since the rigidity of the mat member 20 is such that the user does not substantially feel the amount of deflection depending on the load of the user, the sleeping comfort is good. In addition, from the gap formed between the mat member 20 and the adjacent mat member 20, sewage and defecation about the user can be discharged downward, and the surface layer portion 21 is used as a waterproof member, so cleaning is also possible. It becomes easy.

  In the care bed of the present invention, preferably, for example, as shown in FIGS. 2 and 3, the height of the bed frame 10 that supports the mat member 20 is substantially constant, and the user's neck / back is provided. A mat member with a standard diameter is arranged for the thigh and thigh, and the mat member with the standard diameter is provided at a part corresponding to at least a part of the head, shoulder, and hip including the user's buttocks. It is characterized in that a mat member having a smaller outer diameter is arranged.

  According to the nursing bed having such a configuration, the height at which the mat member 20 of the bed frame 10 is supported is determined by the depth of the concave portion of the bearing member 16, so that it is substantially constant regardless of the user's leaning position. is there. Therefore, for the user's neck, back, thigh, and thigh, a standard-diameter mat member 20 (for example, a large-diameter mat member 203) is installed on the bed frame 10, but the head including the user's buttocks. A mat member (for example, medium-diameter mat member 202 or small-diameter mat member 201) smaller than the standard diameter is preferably disposed at a portion corresponding to at least a part of the shoulder portion or the heel portion. Thereby, the bed surface shape according to the skin distribution shape of the user lying on the bed surface can be obtained, and the surface shape of the bed surface can be made appropriate with little floor displacement.

  In the care bed of the present invention, preferably, for example, as shown in FIGS. 3 and 5, the user's neck, back, thigh, and thigh are adapted to load load when the user applies a load. And a deformation recovery function for recovering the formed depression when the user removes the load is provided with a standard small deformation surface layer 212, and the head, shoulder, and heel including the user's buttocks A large deformation surface layer portion 211 having a larger deformation recovery function than that of the small deformation surface layer portion 212 is arranged at a portion corresponding to at least a part of the portion.

  According to the nursing bed having such a configuration, the user's neck, back, thigh, and thigh are provided with the small deformation surface layer 212, and the head, shoulder, and heel including the user's buttocks. If the large deformation surface layer 211 is arranged for a part corresponding to at least a part of the bed, a bed surface shape corresponding to the skin distribution shape of the user lying on the bed surface is obtained, and the surface shape of the bed surface Can be made appropriate with little bed slip. That is, the head, shoulders, and heel including the user's heel have a larger load acting amount than other parts, so it is desirable that the depression corresponding to the load is large. Since the amount of formation of the dent is large, an excessive reaction force does not act on the facing surface of the large deformation surface layer portion 211, which is desirable.

  In the care bed of the present invention, preferably, as shown in FIGS. 11 and 12, for example, the mat member 20 has the surface layer portion 21 almost fully with respect to the lateral width of the bed frame 10 in the axial direction of the core portion 22. The full width mat member 24, the torso mat member 25 having the surface layer portion 21 corresponding to the torso width with respect to the torso width of the user, and both arms positioned on both sides of the torso of the user, The surface layer portion 21 is provided at a position corresponding to the both arms, and there are three types of the mat member 26 for both arms having a core portion formed at a portion corresponding to the body width. The body mat member 25 is attached to a portion corresponding to the shoulder or the elbow, and the both-arm mat member 26 is attached to a portion corresponding to the shoulder blade or the crotch.

  According to the nursing bed having such a configuration, attention is paid to the fact that the user's bedsore occurrence site is the skin near both shoulders, near the scapula, both elbows, near the tailbone, and near the heel. Can be used properly. That is, the torso mat member 25 is attached to the mat member support portion 17 of the bed frame 10 at the portions corresponding to both shoulders and both elbows. The mat members 26 for both arms are mounted on the mat member support portion 17 of the bed frame 10 in the portions corresponding to the vicinity of the scapula and the tailbone. Then, the full-width mat member 24 is mounted on the mat member support portion 17 of the bed frame 10 in a portion corresponding to the head, neck, thigh, and thigh. Thereby, even if a bed slip occurs, the surface layer portion 21 having a concave surface shape is opposed to the floor slip generation site, thereby preventing the deterioration of the bed slip symptom.

  In the care bed of the present invention, preferably, as shown in FIGS. 6 and 7, for example, the mat member 20 is rotatably supported with respect to the bed frame 10, and the mat member support portion 17 of the bed frame 10 is The supporting mat member 20 is supported so as to be able to vibrate in at least one of the height direction and the adjacent mat member direction, or the supporting mat member 20 is rotated or rotated in a predetermined manner, and the vibration, rotation or It is characterized by having a skin massage function for the user by rotation.

  According to the nursing bed having such a configuration, the mat member support portion 17 supports the mat member 20 so as to vibrate in at least one of the height direction and the adjacent mat member direction. It can be displaced in various ways, such as moving in the width direction, moving the mat member 20 up and down, shaking in the width direction, moving the mat member 20 back and forth, and shaking in the vertical direction. Therefore, the function of massaging the skin is exhibited, and the occurrence of bed slip can be prevented. In addition, the mat member support portion 17 prevents the user from causing a floor slip by rotating the mat member 20 to be supported at a predetermined rotation speed.

  In the care bed of the present invention, preferably, for example, as shown in FIG. 14, the mat member 20 is supported by the concave portion 17 formed in the bed frame 10 and covers the concave portion 17 on the upper portion of the concave portion 17. A stopper portion 19 that opens and closes between the open state and the open state is provided. With the stopper portion 19 open, the mat member 20 is attached to and detached from the concave portion 17, and the concave portion 17 and the stopper portion are closed with the stopper portion 19 closed. 19, the mat member 20 is sandwiched therebetween. According to the nursing bed having such a configuration, when the mat member 20 is positioned in the concave portion 17, the stopper portion 19 is closed and the concave portion 17 is covered with the stopper portion 19. Restrained by the portion 19. This prevents the mat member 20 from being lifted by buoyancy even when the specific gravity of the mat member 20 is smaller than that of water.

  In the care bed of the present invention, preferably, for example, as shown in FIG. 8, the mat member 20 has fluid injection chambers (232, 274) in the interior covered with the surface layer portions (21, 27), Fluid adjusting portions (216, 219, 276) for adjusting the diameter of the mat member 20 or adjusting the surface shape of the surface layer portion 21 by injecting fluid into the fluid injection chamber or sucking the injected fluid. And the amount of fluid injected into the fluid injection chamber is adjusted by the fluid adjustment unit so as to prevent the occurrence of bed slipping by the user.

  According to the nursing bed having such a configuration, since the mat member has the fluid injection chamber, the surface shape of the surface layer portion 21 is adjusted according to the amount of fluid injected like a rubber balloon. Therefore, a bed surface shape corresponding to the skin distribution shape of the user lying on the bed surface can be obtained, and the surface shape of the bed surface can be made appropriate with little floor displacement. Further, by injecting or sucking fluid into the fluid injection chamber 232 by the fluid adjusting unit, and deforming the surface shape of the surface layer portions (21, 27), a massage function for the skin is exhibited, The occurrence of bedsores can be prevented.

  In the care bed of the present invention, preferably, for example, as shown in FIG. 9, the mat member 20 has a fluid injection chamber 232 in the interior covered with the surface layer portion 21, and a heat storage material with respect to the fluid injection chamber. And the characteristics of the heat storage material are selected so as to be suitable for temperature control such as heat insulation or cold insulation for the user. According to the nursing bed having such a configuration, the mat member 21 injects the heat storage material into the fluid injection chamber 232, so that the mat member 21 is suitable for temperature control such as heat insulation and cold insulation for the user of the nursing bed. A comfortable sleeping state can be provided to the user by selecting the characteristics of the heat storage material.

  In the care bed of the present invention, the mat member 20 is preferably characterized in that the surface layer portion 21 is subjected to at least one of antibacterial treatment and sterilization treatment. According to the nursing bed of such a configuration, since the surface layer portion 21 has been subjected to antibacterial treatment or sterilization treatment, even if the user is living on a mat member for a long period of time, Proliferation of miscellaneous bacteria is suppressed, and damage to the skin due to the occurrence of bed slippage by the user can be prevented.

  In the care bed of the present invention, preferably, as shown in FIG. 13, for example, the bed frame 10 is provided with a plurality of width connecting members 102 and vertical connecting members 104 that form a mesh mattress inside the frame. The installation interval between the member 102 and the vertical connecting member 104 is characterized in that it is determined so as not to obstruct the mounting of the mat member 20. According to the nursing bed having such a configuration, the mesh mattress composed of the width connecting member 102 and the vertical connecting member 104 is positioned below the mat member 20, so that the interval between the adjacent mat members 20 is excessively large. Even so, the movement of a part of the user's body is restricted by the mesh mattress from the gap, so that the possibility of touching the bathtub is reduced.

  According to the configuration of the present invention described in claim 1, the surface layer portion 21 is formed of a waterproof member having a deformability enough to form a depression corresponding to a load applied by a user. A bed surface shape corresponding to the skin distribution shape of the user lying on the side is obtained. Further, even if the user turns over and the load distribution changes, the shape of the depression is deformed in an adaptive state by the deformation function of the surface layer portion 21, and the sleeping comfort is improved.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a structural perspective view for explaining an embodiment of a care bed according to the present invention, showing a case of a care bed with a bathtub, wherein (A) is a care bed and (B) is a bathtub. Show. In the figure, the bed for nursing care is composed of a bed frame 10, a column 12, a suspension column 13, a hook stopper 14, a safety frame 15, a bearing member 16, and a mat member 20. The bed frame 10 is made of a frame frame material for forming a bed surface at a position of about 70 to 90 cm in height from the floor. The frame frame material is made of a material with high rigidity, such as a metal such as steel, or a glass fiber reinforced plastic material, and its shape is both lightweight and rigid like a pipe. . The bed frame 10 is typically designed with one sleeping person in mind, and is, for example, about 70 cm to 100 cm in the width direction of the sleeping person and about 180 cm to 220 cm in the longitudinal direction.

  The support columns 12 are provided at the four corners of the bed frame 10 and, for example, steel pipe materials are used. The suspension column 13 is provided, for example, by bending the tip of the column 12 into a U shape, and supports the four corners of the bed frame 10 at a predetermined height. A space S having a width of about 3 cm to 10 cm is provided between the support column 12 and the suspension support column 13, which is provided for convenience when the bathtub 30 is used, for example. The hook stopper 14 is a ring-shaped metal fitting provided at the tip connecting portion of the support column 12 and the suspension support column 13, and is used, for example, to suspend a sheet 32 when using a bathtub. The safety frame 15 is formed from frame-shaped rods provided at the four corners of the bed frame 10 and prevents the sleeping person from falling from the bed surface to the floor. In general, the safety frame 15 is detachably attached to the bed frame 10, and the installation of a part of the bed frame 10 is omitted so that the user can easily move to the bed surface. Has been. The bearing members 16 are installed on both sides of the bed frame 10 in the longitudinal direction, and are used to enhance the mounting convenience of the mat member 20. Details of the bearing member 16 will be described later with reference to FIG.

  The mat member 20 is a rod-like member having a cross-sectional shape that is substantially circular, substantially elliptical, or substantially annular. On the premise that the direction in which the user can lean with respect to the bed frame 10 is the vertical direction, the mat members 20 are arranged side by side with respect to the bed frame 10 to form a bed surface. The bed surface is formed by a plurality of mat members 20. For example, a futon or a blanket is laid on the bed surface for the convenience of the user. Details of the mat member 20 will be described later with reference to FIGS. 2, 5 to 10, 12, and 14.

  Next, the bathtub will be described. In addition, although this bathtub uses the bathtub of the sheet | seat top-and-bottom type which the present applicant demonstrated in patent application 2006 No. 250665 specification, this invention is not limited to this. For example, as a bathtub, a conventionally known method of lowering the bed surface via a hammock type or a power mechanism (Patent Document 1), a type in which the bathtub is moved to a bed by an electric lift or a jack mechanism (Patent Document 2), on the bed Alternatively, a bag-like sheet may be placed on the wall, and the wall surface of the sheet may be supported by a vertically moving frame or the like to temporarily form a bathtub (Patent Document 3).

  In the figure, the bathtub has a bathtub case 30, a drain plug 31, a sheet 32, a metal frame 33, wheels 34, and a hook 35. Since the bathtub case 30 is assumed to be movable and positioned between the bed frame 10 of the nursing care bed and the floor, it is about one third of the normal bathtub depth of about 60 cm. This is a shallow rectangular reservoir. The bathtub case 30 can be made of a light metal thin plate or a glass fiber reinforced plastic material. The drain plug 31 is provided at a lower portion of the bathtub case 30. The wheels 34 are provided at the four corners of the bottom surface of the bathtub case 30.

  The sheet 32 is made of a water-resistant material that is attached to the upper part of the bathtub case 30 in an airtight state, and is configured to be stretchable in the vertical direction in a bellows type. For the sheet 32, a light material such as a rubber film, a nylon film, or a vinyl film reinforced with synthetic fiber fibers can be used. The metal frame 33 is a frame-shaped frame member attached to the upper part of the sheet 32, and for example, a steel pipe is used. The shape of the metal frame 33 has a frontage slightly wider than the bed frame 10 of the nursing bed, and seems to be convenient for positioning the sheet 32 in the gap S formed between the support column 12 and the suspension support column 13. It is stipulated in. The hook 35 is used to suspend the hook 32 from the hook stopper 14 in a state where the seat 32 is extended. The hanging position of the hook 35 is determined so that the water level can be secured slightly above the surface of the user lying on the bed surface with the seat 32 stretched, for example, 15 cm to 40 cm from the bed surface. It is determined to the extent.

  FIG. 2 is a structural perspective view for explaining an example of the structure of the mat member. In the figure, the mat member 20 has a surface layer portion 21, a core portion 22, and an annular body 23. The surface layer portion 21 is a portion where the mat member 20 comes into contact with the user, and is configured by a waterproof member having deformability to such an extent that a depression corresponding to a load applied by the user is formed. The surface layer portion 21 is made of a flexible water-repellent material such as foamed polyurethane foam, for example, and preferably has a shape recovery function that recovers to the previous shape when the user gets off the bed surface. The core portion 22 has shaft portions 22 a supported by the bearing member 16 at both ends of the mat member 20. Further, the core portion 22 may have a rod-like or pipe-like rod material for connecting the shaft portion 22a, and may be located concentrically with the surface layer portion 21. The rigidity of the core portion 22 should be configured so that the user does not substantially feel the amount of deflection depending on the load of the user. For example, a user with a weight of about 60 kg lies on the bed frame 10 of the care bed. In this case, the center deflection amount of the individual mat member 20 is determined to be 1 mm or less, for example.

  The torus 23 is wound in multiple layers around the core 22 according to the outer diameter D of the surface layer 21 of the mat member 20. For example, the torus 23 forms the core 22. Mounted concentrically on the rod. For example, the mat member 20 has a large-diameter mat member 203 shown in FIG. 2A, a medium-diameter mat member 202 shown in FIG. 2B, and a small-diameter mat member 201 shown in FIG. There are three types. In this case, the small-diameter mat member 201 has an outer diameter D1 of the surface layer portion 21 of, for example, about 15 cm. And the 1st layer ring body 23a directly wound by the core part 22 has the outer diameter D of about 10 cm. The second layer annular body 23b is wound around the first layer annular body 23a, and the thickness of the second layer annular body 23b is, for example, about 2.5 cm.

  Next, the medium-diameter mat member 202 has an outer diameter D2 of the surface layer portion 21 of, for example, about 20 cm. In this case, in order to manufacture the medium-diameter mat member 202 based on the small-diameter mat member 201, the first-layer torus 23a, the second-layer torus 23b, and the third-layer circle that are directly wound around the core portion 22 are used. A three-layer structure of the ring body 23c is preferable. The third layer annular body 23c is wound around the second layer annular body 23b, and the thickness of the third layer annular body 23c is, for example, about 2.5 cm. The large-diameter mat member 203 has an outer diameter D3 of the surface layer portion 21 of, for example, about 25 cm. In this case, in order to manufacture the small-diameter mat member 201 based on the medium-diameter mat member 202, the first-layer torus 23a, the second-layer torus 23b, and the third-layer circle that are directly wound around the core portion 22. A four-layer structure of an annular body 23c and a fourth-layer annular body 23d is preferable. The fourth layer annular body 23d is wound around the third layer annular body 23c, and the thickness of the fourth layer annular body 23d is, for example, about 2.5 cm.

  As described above, the structure in which the annular body 23 is wound in multiple layers according to the outer diameter D of the surface layer portion 21 of the mat member 20 exhibits a mass production effect and helps to reduce the manufacturing cost. Further, the standard number of mat members 20 installed on the bed frame 10 changes according to the outer diameter D of the surface layer portion 21. For example, the standard is 12 for the small-diameter mat member 201, 9 for the medium-diameter mat member 202, and 7 for the large-diameter mat member 203.

  FIGS. 3A and 3B are explanatory diagrams in the case where the outer diameter of the mat member is adjusted according to the part of the user lying on the bed surface, FIG. 3A is a plan view, FIG. 3B is a front view, and FIG. ) Shows a front view of the bearing member. As names for the human body, it is divided into head, neck, shoulder, back, buttocks, thigh, thigh, and buttocks. By selecting the outer diameter of the mat member corresponding to each part of the body, the surface shape of the bed surface can be made appropriate with little floor slip. Bed sores refer to red sores that occur on the skin surface due to prolonged recumbency and are also called pressure ulcers.

  The height at which the mat member 20 of the bed frame 10 is supported is determined by the depth of the concave portion 17 of the bearing member 16, and is therefore constant regardless of the position where the user can lean in the vertical direction. Therefore, for the user's neck, back, thigh, and thigh, the large-diameter mat member 203 is used as a standard member of the mat member 20 installed on the bed frame 10, but the head including the user's buttocks It is preferable that a medium-diameter mat member 202 or a small-diameter mat member 201 is disposed at a portion corresponding to at least a part of the shoulder portion / buttock portion. Thereby, the surface shape of the bed surface can be made appropriate with little floor displacement. Since the surface layer portion 21 of the mat member 20 is made of a flexible water-repellent material such as foamed polyurethane foam, it is suitable for dealing with floor slip. Here, there are two types of hook stoppers 14, an upper hook stopper 14 a provided at the upper end of the column 12 and a hook stopper 14 b provided in the middle of the suspension column 13. Now, the seat 32 can be suspended.

  FIG. 4 is a structural perspective view for explaining a state in which the bathtub case is positioned at the lower part of the bed frame with the sheet compressed, and shows a state in which the mat member and the bearing member are removed. The lower surface of the bed frame 10 is opened to the inner tank of the bathtub case 30 through the opening of the sheet 32. Thus, when the user uses a shower while the mat member 20 is mounted on the bed frame 10, the hot water of the shower flows from the gap of the mat member 20 into the inner tub of the bathtub case 30, stay. Therefore, drainage can be easily performed by connecting an appropriate drainage hose to the drain plug 31.

  FIG. 5 is a structural perspective view for explaining a second embodiment of the structure of the mat member. In the embodiment of FIG. 2, the bed surface shape corresponding to the body shape is obtained by changing the outer diameter D of the surface layer portion 21 of the mat member 20. However, even if the outer diameter D of the surface layer portion 21 of the mat member 20 is kept constant, a bed surface shape corresponding to the same body shape can be obtained by appropriately selecting the deformation function of the surface layer portion 21. FIG. 5A shows the case of the large deformation surface layer portion 211, and FIG. 5B shows the case of the small deformation surface layer portion 212. The large deformation surface layer portion 211 has a large deformation amount of deformation when the load is applied and a large deformation recovery function that recovers the depression formed when the load is removed. For example, the foamed polyurethane foam layer used for the surface layer portion 21 is 5 to 5, for example. Thicken it as 10cm. Compared with the large deformation surface layer portion 211, the small deformation surface layer portion 212 has a small amount of depression deformation at the time of load application. For example, the foamed polyurethane foam layer used for the surface layer portion 21 is thinned, for example, 2 to 3 cm. .

  Since the height at which the mat member 20 of the bed frame 10 is supported is determined by the depth of the concave portion of the bearing member 16, the height is constant regardless of the position where the user can lean in the vertical direction. Therefore, for the user's neck, back, thigh, and thigh, the small deformation surface layer 212 is used as a standard member of the mat member 20 installed on the bed frame 10, but the head including the user's buttocks A portion corresponding to at least a part of the shoulder portion or the heel portion is preferably provided with a large deformation surface layer portion 211. The height of the bed frame 10 that supports the mat member 20 is the standard height for the user's neck, back, thigh, and thigh, but the head and shoulders including the user's buttocks -You may adjust the depth of the recessed part of the bearing member 16 so that the site | part corresponding to at least one part of a collar part may become lower than standard height.

  6A and 6B are configuration perspective views for explaining a mat member according to a third embodiment. FIG. 6A is a configuration perspective view of a main part of a nursing bed, and FIG. 6B is a configuration diagram of a bearing member. Here, the surface layer 21 of the mat member 20 facing the skin of the user lying on the bed surface is displaced to prevent bed slippage. That is, the bearing member 16 is formed with a concave portion 17 for supporting the individual mat member 20. Here, assuming that the above-described large-diameter mat member 203 is used as the mat member 20, the bearing member 16 is used for seven standard members. The recess 17 is formed.

The actuators 18a, 18b, and 18c may be fluid-driven pistons that are driven by a fluid such as hydraulic pressure or air pressure. Also, a piezoelectric element that is displaced by a voltage signal or an electrostrictive element that is displaced by a current signal. It may be used. The control line 18d may be provided individually on a one-to-one basis so that the actuators 18a, 18b, and 18c operate independently on the individual mat member 20, and are also three-dimensional in the vertical direction, the front-rear direction, and the left-right direction.

  11A and 11B are configuration diagrams for explaining a ninth embodiment of the arrangement of mat members. FIG. 11A is an explanatory view of a user's bed slipping portion lying on the bed surface, and FIG. 11B is an explanatory view of the arrangement of the mat members. It is. FIG. 12 is a structural perspective view for explaining a mat member suitable for use in the embodiment of FIG. 11, wherein (A) is a first type having a uniform axial diameter distribution, and (B) is a second swelled central portion. Type (C) is an explanatory diagram of a third type with a depressed central part. The first type is a full-width mat member 24 that has a surface layer portion 21 that is substantially full with respect to the lateral width of the bed frame 10 in the axial direction of the core portion 22. The core portion 22 of the full width mat member 24 has shaft portions 22 a supported by the bearing member 16 at both ends of the full width mat member 24. The second type is a trunk mat member 25 having a surface layer portion 21 corresponding to the trunk width with respect to the trunk width of the user. The core portion 22 of the trunk mat member 25 has a shaft portion 22 a supported by the bearing member 16 and a core portion 22 b positioned between the shaft portion 22 a and the surface layer portion 21. The diameter of the core portion 22b may be the same as that of the shaft portion 22a, or may be intermediate between the diameter of the shaft portion 22a and the surface layer portion 21. The third type is a mat member 26 for both arms, which has a surface layer portion 21 at a position corresponding to both the arms on both sides of the user's torso, and a portion corresponding to the torso width. A core portion 22c is formed. The core portion 22 of the both-arm mat member 26 has shaft portions 22 a supported by the bearing member 16 at both ends of the both-arm mat member 26.

  As shown in FIG. 11 (A), the bedsore part of the user lying on the bed surface is skin near both shoulders, near the scapula, both elbows, near the tailbone, and near the heel. Therefore, the torso mat member 25 is attached to the recess 17 of the bed frame 10 corresponding to both shoulders and both elbows. The mat members 26 for both arms are attached to the recesses 17 of the bed frame 10 at portions corresponding to the vicinity of the shoulder blades and the vicinity of the tailbone. Then, the full width mat member 24 is attached to the concave portion 17 of the bed frame 10 corresponding to the head, neck, thigh, and thigh. For the skin near the heel, if a large-diameter mat member is placed near the ankle, the vicinity of the heel will float, so the full-width mat member 24 or the torso mat member 25 or the both-arms mat member 26 may be used. .

  13 is a structural perspective view for explaining a tenth embodiment of a nursing bed. Compared with the nursing bed with a bathtub in FIG. 1, (A) is a nursing bed excluding a mat member, and (B). Represents a bathtub, and (C) represents a mat member arrangement. In 10th Embodiment, the shape of the bed frame 10 is devised with respect to the nursing bed with a bathtub of FIG. That is, since the bed frame 10 of FIG. 1 is a frame frame material, it is hollow when the mat member 20 is not mounted. Then, when the interval between the adjacent mat members 20 becomes excessive, a part of the user's body may touch the bathtub from the gap. If the bathtub is wet, a part of the user's body, for example, a hand or a foot, gets wet, and it is expected that it is not preferable for the caregiver.

  Therefore, several width connecting members 102 are installed on the bed frame 10 in the width direction of the sleeping person, and several vertical connecting members 104 are installed in the head and foot direction of the sleeping person. Then, the mat member 20 is disposed above the width connecting member 102 and the vertical connecting member 104. The installation locations of the width connecting member 102 and the vertical connecting member 104 are determined so that the mat member 20 can be easily supported by the recess 17 of the bed frame 10. For example, the width connecting member 102 and the vertical connecting member 104 may function as a reticulated hammock-like mesh mattress. The installation interval between the width connecting member 102 and the vertical connecting member 104 that defines the mesh shape of the reticulated mattress is preferably determined so as not to impede the mounting of the mat member 20.

  If comprised in this way, since the net-like mattress comprised from the width | variety connection member 102 and the vertical connection member 104 is located in the lower side of the mat member 20, even if the space | interval of the adjacent mat member 20 becomes excessive, it will be from a clearance gap. Since a part of the user's body is restrained from moving by the mesh mattress, the possibility of touching the bathtub is reduced. Then, even when the bathtub is wet, a part of the user's body, for example, hands and feet can be prevented from getting wet, which is preferable for the caregiver.

  FIG. 14 is a structural perspective view for explaining an eleventh embodiment of the mat member. FIG. 14A is a side view of the main part in the vicinity of the recess for supporting the individual mat member, and FIG. The principal part top view of the other bearing member, (C) is a principal part top view explaining a use condition. The bearing member 16 has a recess 17 for supporting the individual mat member 20. Therefore, a case where the shaft portion 22a of the mat member 20 is positioned in the concave portion 17 and attached to hot water will be considered. The state in which the mat member 20 is immersed in hot water occurs when the sheet 32 is hung on the hook stopper 14 in a state where the sheet 32 is extended and hot water is stored in the sheet 32 as shown in FIG. Is. The hanging position of the hook 35 is determined so that the water level can be secured slightly above the surface of the user lying on the bed surface in a state where the seat 32 is stretched, so that the mat member 20 is submerged. . Then, when the specific gravity of the mat member 20 is smaller than that of water, there arises a problem that the mat member 20 is lifted by buoyancy.

  Therefore, even when the specific gravity of the mat member 20 is smaller than that of water, a stopper portion 19 may be provided on the upper portion of the concave portion 17 in order to prevent the mat member 20 from being lifted by buoyancy. The stopper portion 19 is pivotally supported on the bearing member 16 by a shaft portion 192 so as to be rotatable within a predetermined range. Therefore, in a state where the stopper portion 19 is opened, the concave portion 17 is not covered with the stopper portion 19, so that the shaft portion 22 a of the mat member 20 can be positioned in the concave portion 17. Then, after positioning the shaft portion 22 a of the mat member 20 in the recess portion 17, when the stopper portion 19 is closed and the recess portion 17 is covered with the stopper portion 19, the shaft portion 22 a is restrained by the recess portion 17 and the stopper portion 19. This prevents the mat member 20 from being lifted by buoyancy even when the specific gravity of the mat member 20 is smaller than that of water.

  As mentioned above, although embodiment of this invention was described with reference to an accompanying drawing, this invention is not limited to this embodiment, Various forms in the technical scope grasped | ascertained from description of a claim Can be changed. For example, although the shape of the bed frame has been described on the assumption that the cared person has a standard Japanese adult body shape, the present invention is not limited to this, and may be for children, for example. Also, it may be for those with a large body.

Furthermore, the surface layer of the mat member 20 may be subjected to antibacterial treatment or deodorization treatment. Antimicrobial effect (antibacterial-) refers to the prevention of bacterial growth, and is a concept that does not include the target or degree of inhibition of growth. In the antibacterial specification product of JIS standard (JIS Z 2801), mold, darkening and slime are excluded from the effect. As the antibacterial treatment, iodine impregnation, titanium oxide / graft polymerization and the like are known methods. Graft polymerization refers to bonding another polymer chain to one polymer chain. An active site is formed on the polymer chain by irradiation or a catalyst, thereby starting polymerization of another monomer to synthesize a graft polymer. A mat member suitable for antibacterial treatment and deodorization treatment can be obtained by graft polymerization of another monomer to a polymer material such as fiber or plastic.
