Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a hospital bed. Background Art

[0002] During the operation or examination of a patient, the patient needs to be transferred multiple times among various hospital beds (for example, the patient needs to be transferred to an operation trolley before the operation and then go to the operating room). For patients who can still move, the transfer among various hospital beds can be completed by themselves. However, for patients with weak mobility, usually the family members need to cooperate with the medical staff to carry the patient back and forth, which is a great burden and is also likely to cause harm to the patient during the carrying process. Especially for patients with a large body weight, it is often difficult for the medical staff to carry and transfer them at present.

[0003] In view of this, it is necessary to design a hospital bed that can facilitate the transfer of patients. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hospital bed that can facilitate the transfer of patients between different hospital beds, which is not only time-saving and labor-saving, but also does not require moving the patient, reducing or avoiding damage and pain to the patient.

[0028] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present utility model are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0030] The upper, lower, left, right, front, back, top, bottom, etc. (if any) directional terms involved in the description and claims of the present utility model are defined based on the positions of the structures in the drawings and their relative positions to each other, solely for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by the present utility model.

[0031] As Figures 1 to 5 shown, the hospital bed provided by the embodiment of the present utility model includes a bed frame 1 and a mattress 2 disposed on the bed frame 1. A roller assembly 3 is connected to the bottom of the bed frame 1. The roller assembly 3 includes a plurality of rollers 31 spaced apart from each other. The rollers 31 can roll relative to the bed frame 1 so that the bed frame 1 can move.

[0032] The bed frame 1 has a length direction L and a width direction W perpendicular to each other. A sliding assembly 4 is provided on the bed frame 1 (specifically, the sliding assembly 4 is disposed on the part of the bed frame 1 for placing the mattress 2). The sliding assembly 4 is located between the bed frame 1 and the mattress 2. The mattress 2 can slide horizontally relative to the bed frame 1 along the width direction W (that is, the mattress 2 is placed on the sliding assembly 4, and the mattress 2 can slide horizontally relative to the bed frame 1 through the sliding assembly 4), so that the mattress 2 of one hospital bed can be transferred to the bed frame 1 of another hospital bed.

[0033] First positioning structures 11 and second positioning structures 12 are respectively provided on the opposite side portions of the bed frame 1 along its width direction W. The first positioning structure 11 and the second positioning structure 12 are correspondingly arranged (in this embodiment, the first positioning structure 11 and the second positioning structure 12 are located on the same horizontal line in the width direction W). The first positioning structure 11 on one hospital bed can cooperate with the second positioning structure 12 on another hospital bed to achieve the positioning between two hospital beds when the mattress 2 is transferred.

[0034] As Figures 2 to 5 and Figure 7 shown, as an implementation manner, the sliding assembly 4 includes a plurality of flow bar assemblies 41. Each flow bar assembly 41 extends along the width direction W, and the plurality of flow bar assemblies 41 are arranged at intervals along the length direction L. Due to the reliable structure and high stability of the flow bar assemblies 41, the plurality of flow bar assemblies 41 can well support the mattress 2, facilitating the sliding of the mattress 2; at the same time, the cost of the flow bar assemblies 41 is relatively low, which can reduce the production cost of the hospital bed.

[0035] Specifically, the fluent strip assembly 41 includes a base 411 with a long strip structure and a plurality of sliding wheels 412 arranged on the base 411. The base 411 extends along the width direction W, and the plurality of sliding wheels 412 are arranged at intervals along the width direction W on the base 411. Each sliding wheel 412 is rotatably connected to the base 411, and the sliding wheel 412 can rotate relative to the base 411. The base 411 is fixedly connected to the bed frame 1, and the mattress 2 is placed on the sliding wheels 412 of the fluent strip assembly 41. When the mattress 2 is pushed / pulled by hand, the mattress 2 can slide horizontally. The specific structure of the fluent strip assembly 41 can refer to the prior art and will not be elaborated here.

[0036] As Figure 8 shown and in combination with Figure 4 , as another embodiment, the sliding assembly 4 includes a plurality of synchronous belt drive assemblies 42. Each synchronous belt drive assembly 42 extends along the width direction W, and the plurality of synchronous belt drive assemblies 42 are arranged at intervals along the length direction L. The synchronous belt drive assembly 42 specifically includes a drive motor (not shown in the figure), a driving wheel 421, a driven wheel 422 (the number of the driving wheel 421 and the driven wheel 422 can be one or more), and a synchronous belt 423 wound around the driving wheel 421 and the driven wheel 422. The mattress 2 is placed on the synchronous belt 423; the drive motor is connected to the driving wheel 421, and the drive motor is used to drive the driving wheel 421 to rotate, thereby driving the synchronous belt 423 and the driven wheel 422 to rotate, and further driving the mattress 2 to slide horizontally. The specific structure of the synchronous belt drive assembly 42 can refer to the prior art and will not be elaborated here. This way of driving the mattress 2 to slide horizontally by using the synchronous belt drive assembly 42 does not require manual pushing of the mattress 2 by hand, thus being more labor-saving (when in use, only the switch controlling the drive motor needs to be turned on).

[0037] As Figures 2 to 6 shown, as an embodiment, the hospital bed further includes a slide rail assembly 5. The slide rail assembly 5 includes a cooperating upper slide rail 51 and a lower slide rail 52, and the upper slide rail 51 can slide along the lower slide rail 52. Both the upper slide rail 51 and the lower slide rail 52 extend along the width direction W. The upper slide rail 51 is arranged on the lower surface of the mattress 2, and the lower slide rail 52 is arranged on the upper surface of the bed frame 1. By providing the slide rail assembly 5, not only can it play a certain supporting role for the mattress 2, but also enable the mattress 2 to slide more smoothly, and at the same time can play a guiding / limiting role for the horizontal sliding of the mattress 2, avoiding the mattress 2 from shifting in position during the horizontal sliding process (the sliding assembly 4 helps the mattress 2 to slide horizontally and generally cannot guide / limit the horizontal sliding of the mattress 2).

[0038] As Figures 2 to 5As shown, as an implementation manner, the number of slide rail assemblies 5 is multiple, and the multiple slide rail assemblies 5 are arranged at intervals along the length direction L; that is, the lower slide rails 52 of the multiple slide rail assemblies 5 are arranged at intervals along the length direction L on the upper surface of the bed frame 1, the upper slide rails 51 of the multiple slide rail assemblies 5 are arranged at intervals along the length direction L on the lower surface of the mattress 2, and the upper slide rails 51 of the multiple slide rail assemblies 5 respectively correspond to the lower slide rails 52 of the multiple slide rail assemblies 5 one by one. In this embodiment, the number of slide rail assemblies 5 is two, and the two slide rail assemblies 5 are respectively arranged on both sides of the bed frame 1 along the length direction L.

[0039] As Figures 1 to 5 shown, as an implementation manner, blocking members 13 are provided on the side portions of the opposite sides of the bed frame 1 along its width direction W, and the blocking members 13 are used to prevent the mattress 2 from falling off the bed frame 1 (that is, the blocking members 13 can block the mattress 2 to prevent it from sliding freely). The blocking members 13 are movably connected to the bed frame 1, so that the blocking members 13 can be moved away when the mattress 2 needs to slide horizontally, so that the mattress 2 can slide normally.

[0040] As Figures 1 to 5 shown, as an implementation manner, the blocking member 13 is a guardrail, and the guardrail is rotatably connected to the bed frame 1. When the guardrail rotates to the vertical state (that is, in the state shown in Figure 5 ), the guardrail does not block the mattress 2, and the mattress 2 can slide horizontally relative to the bed frame 1; when the guardrail rotates to the standing state (that is, in the state shown in Figure 4 ), the guardrail can block the mattress 2, and at this time the mattress 2 cannot slide horizontally relative to the bed frame 1. At the same time, a damping structure (not shown in the figure) or a locking structure (not shown in the figure) is provided at the rotation connection position of the guardrail and the bed frame 1, so that the guardrail can be kept in the standing state. Of course, in other embodiments, the blocking member 13 can also be a movable pin shaft (not shown in the figure) and other structures.

[0041] As Figures 1 to 5 shown, as an implementation manner, the bed frame 1 includes a bed body 14 and a support frame 15 connected to each other. The support frame 15 is arranged at opposite ends of the bed body 14 along the length direction L. A part of the support frame 15 is located above the bed body 14, and another part of the support frame 15 is located below the bed body 14; the roller assembly 3 is arranged at the bottom of the support frame 15.

[0042] The bed body 14 includes two longitudinal beams 141 and multiple cross beams 142. Each longitudinal beam 141 extends along the length direction L, and the two longitudinal beams 141 are arranged at intervals along the width direction W; each cross beam 142 extends along the width direction W, and both ends of each cross beam 142 are respectively connected to the two longitudinal beams 141, and the multiple cross beams 142 are arranged at intervals along the length direction L. The sliding assembly 4 and the lower slide rail 52 are both arranged on the cross beam 142 (the sliding assembly 4 and the lower slide rail 52 can be specifically connected to the cross beam 142 by bolts), and the first positioning structure 11 and the second positioning structure 12 are respectively arranged on the two longitudinal beams 141. Of course, in other embodiments, the sliding assembly 4 and the lower slide rail 52 can also be arranged between adjacent cross beams 142.

[0043] As Figures 1 to 5 shown, as an implementation manner, the first positioning structure 11 is a convex rod, and the second positioning structure 12 is a socket hole that is inserted and cooperated with the convex rod. That is, during positioning, the convex rod on one hospital bed can be inserted into the socket hole on another hospital bed, so as to realize the positioning between two hospital beds when the mattress 2 is transferred. At the same time, the convex rod is rotatably connected to the bed frame 1, and the convex rod can be rotated to a horizontal state (that is, when in the state as Figure 5 shown) or a vertical state (that is, when in the state as Figure 4 shown), so that the convex rod can protrude when positioning is required, and can be folded and stored when positioning is not required. At the same time, a damping structure (not shown in the figure) or a locking structure (not shown in the figure) and the like are provided at the rotational connection position of the convex rod and the bed frame 1, so that the convex rod can be kept in a horizontal state, and thus it is convenient to perform positioning docking with the socket hole.

[0044] As Figures 1 to 5 shown, as an implementation manner, the number of the first positioning structure 11 and the second positioning structure 12 is multiple, and the multiple first positioning structures 11 and the multiple second positioning structures 12 are both arranged at intervals along the length direction L, and the multiple first positioning structures 11 are respectively arranged in one-to-one correspondence with the multiple second positioning structures 12. Of course, in other embodiments, the first positioning structure 11 and the second positioning structure 12 can also be other docking structures. For example, one of the first positioning structure 11 and the second positioning structure 12 is a lock (not shown in the figure), and the other of the first positioning structure 11 and the second positioning structure 12 is a locking member (not shown in the figure) that can be locked and cooperated with the lock, etc.

[0045] As Figures 1 to 3 shown, as an implementation manner, the roller assembly 3 includes four rollers 31, and the four rollers 31 are respectively arranged at the four corner positions at the bottom of the bed frame 1; along the length direction L, the two rollers 31 on at least one side of the bed frame 1 are universal wheels (that is, the two rollers 31 on at least one support frame 15 are universal wheels), so as to facilitate the movement and turning of the hospital bed. In this embodiment, all four rollers 31 are universal wheels.

[0046] As an implementation manner, when transferring a patient from one hospital bed to another, the working mode of the hospital bed is as follows:

[0047] A patient lies on the mattress 2 of one hospital bed, and the mattress 2 is not provided on the bed frame 1 of the other hospital bed. Move the hospital bed without the mattress 2 to the vicinity of the hospital bed with the patient lying on it (or move the hospital bed with the patient lying on it to the vicinity of the hospital bed without the mattress 2), then rotate the guardrails on the two hospital beds to the vertical state, and rotate the convex rod on one hospital bed to the horizontal state; move one of the hospital beds so that the convex rod on one hospital bed is inserted into the insertion hole of the other hospital bed to achieve the positioning between the two hospital beds; then slide the mattress 2 together with the patient horizontally from one hospital bed to the other hospital bed, and then rotate the guardrail to the standing state, thus completing the transfer of the patient.

[0048] The hospital bed provided by the embodiment of the present utility model enables the hospital bed to move by arranging the roller assembly 3 at the bottom of the bed frame 1; enables the mattress 2 to slide horizontally relative to the bed frame 1 by arranging the sliding assembly 4 on the bed frame 1, so that the mattress 2 of one hospital bed can be transferred to the bed frame 1 of the other hospital bed; at the same time, by arranging the mutually cooperating first positioning structure 11 and second positioning structure 12, when the mattress 2 is transferred, the two hospital beds can be quickly positioned, thereby avoiding the abnormal transfer of the mattress 2 caused by the misalignment of the two hospital beds, realizing the quick transfer of the mattress 2 and the patient, and being convenient for use. Moreover, the structure of the hospital bed is simple, has strong practicability, and has a relatively low manufacturing cost.

[0049] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
