Description

Technical Field

[0001] The invention relates to the field of medical supplies and equipment, in particular to a hospital bed, in particular to a hospital bed combined with a stretcher for a ward. Background Art

[0002] At present, the shortage of medical resources has become an increasingly prominent social problem. How to solve the problem of shortage of medical resources is inseparable from the optimization and improvement of every detail in the medical field.

[0003] In particular, the inpatient department is the "hardest hit area" of medical resources. The beds are in short supply and it is often difficult to find a bed. Under such a background, the number of beds in the ward is usually arranged relatively full. Therefore, there will be a situation where the beds occupy the aisle space in the ward. In such a case, there will be problems with inconvenience in movement, or when the patient needs to undergo surgery, it is necessary to transfer from the bed to the mobile stretcher. This process is very inconvenient and requires manpower to carry the patient to the stretcher. This is likely to cause the patient to be injured again during the process of manpower transportation, and it is also likely to cause pain to the patient; similarly, when arriving at the operating room or treatment room, the patient must be carried from the stretcher to the operating bed. The patient needs to undergo four transportation processes for a whole round trip, which is not easy, and this transportation process generally requires more than two people. In addition, the aisles in the ward are crowded, which is not only time-consuming and labor-intensive, but also very inconvenient, and there are also great safety hazards. The problem to be solved by the present invention is how to effectively and properly realize the transfer of patients between beds and stretchers. Summary of the invention

[0016] The working principle of the present invention is introduced as follows: the hospital bed of the present invention is composed of a main bed body and a stretcher bed body. The stretcher bed body can be separated from the main bed body and directly used as a stretcher. The patient lies on the stretcher, omitting the process of carrying the patient and transferring the bed body. The combined bed of the present invention can be divided into two states. One is the daily combined state. In this state, the main bed body of the hospital bed and the stretcher bed body are combined to form a flat bed surface, which is composed of the fixed bed body and the bed board of the movable bed wing itself, plus the stretcher bed surface of the stretcher bed body. The size of the bed surface is consistent with the size of a common hospital bed and is flat and stable. When it is necessary to transport and move the patient, the movable brackets used to support the movable bed wing are first flipped over and stored, and then the movable bed wing is flipped upward. The movable bed wing is hingedly connected to the movable bed wing rotating shaft through the wing arms at both ends, so that it is flipped upward relative to the fixed bed body and above it, freeing up a lateral exit area. At this time, the rear steering wheels of the stretcher bed body are lowered to the supporting ground. After the rear wheels are suspended in the air, the stretcher bed body can be moved horizontally relative to the hospital bed out of the fixed bed body by relying on the front guide wheels and the rear steering wheels at the front end. Thus, the patient can enter the aisle, and then retract the rear steering wheel. Relying on the larger rear wheel as the main wheel, the stretcher bed can provide stability and comfort during the travel process. At this time, the stretcher bed can be used as a stretcher. In this process, the mattress can be used for functional settings. For example, the mattress ailerons on both sides of the main mattress can be vertically erected to form side guards on both sides to provide protection during the movement. The aileron flap can also be further unfolded and connected to each other at the top, so that the main mattress below, the mattress ailerons on both sides, and the aileron flap above form a cylindrical silo, which can provide better protection for the patient in the cylindrical silo and protect the patient's privacy. The aileron flap can be folded and stored under the mattress aileron in daily state. At the same time, the four lifting columns of the frame can provide a stretcher lifting rod to realize the lifting of the stretcher bed surface, so that the stretcher bed surface can meet the use requirements of different heights and further improve the applicability. After the operation is completed, when returning to the main bed body of the hospital bed, the movable bed wing is first flipped up to open the entrance and exit area, and after the stretcher bed body is moved to the positioning area, the rear steering wheel is controlled to descend to support the rear wheels, and the stretcher bed body is moved horizontally into the fixed bed body, and its height is adjusted to keep it flush with the bed surface of the fixed bed body, and then the movable bed wing is lowered, the movable bracket is opened to support it on the ground, the rear steering wheel is retracted, the mattress aileron is laid flat, and the aileron collar is stored, that is, the main mattress and mattress aileron are fully spread out on the bed surface of the main bed body of the hospital bed, which is the same size, flatness and comfort as ordinary beds. At the same time, a bed surface movable frame is also provided on the stretcher bed surface. The bed surface movable frame includes an upper body movable frame and a lower body movable frame. The two are lifted and lowered at one end through a telescopic top rod, that is, the upper body movable frame or the lower body movable frame can be driven to achieve a sloped rise, which is convenient for patients to achieve a sitting posture, a bent leg posture, etc.

[0017] The beneficial effects of the present invention are introduced as follows:

[0018] (1) The bed and stretcher are combined into one, which can be used as a bed. When the patient needs to be moved for examination or surgery, the stretcher embedded in the bed can be separated and the patient can be directly pushed away. When the patient returns to the ward, the stretcher can be directly embedded in the bed. This avoids repeated movement of the patient, reduces the patient's pain, and avoids safety hazards such as possible secondary injuries.

[0019] (2) On the premise of achieving the same specifications and comfort as standard beds, through reasonable and ingenious structural design, the stretcher bed can be entered and exited from one long side of the bed, and can pass through narrow bed spacing and aisles. This process can be achieved by a single person, such as the patient's family or a nurse. It saves time and effort, is safe, reliable, convenient and fast.

[0020] (3) The structural design is reasonable and scientific. The flexible connection structure of the mattress can be used as a guardrail during the movement of the stretcher bed. The upper part can also be surrounded and closed to protect the privacy of the patient during the movement and to protect him from wind and sun during the journey. It is also easy to store and can be used as a regular mattress in daily life, realizing the characteristics of one item with multiple uses, easy storage, and combined use.

[0021] (4) The fixed bed and the stretcher bed are designed to be compatible with each other, with ingenious structural design, good compatibility, and reasonable space occupation. The controller and power supply are installed at the bottom of the frame, which can lower the center of gravity and maintain the overall stability of the stretcher. The rear wheels are large, providing stability and comfort during the travel of the stretcher. The rear steering wheels provide convenience for lateral movement in and out of the fixed bed. The two complement each other and are the premise and basis for the comfort and ease of use of each link.

[0022] (5) It has the same sitting-up and lifting structure functions as a standard hospital bed, and can provide auxiliary posture functions such as sitting, lifting legs, and bending legs. By utilizing the structure of movable bed wings and fixed bed body, the stretcher bed body can be located between the two. When used as a combination bed in daily life, the stretcher bed body has better stability, narrow joints, and will not cause shaking. It has high integrity, strong stability, and is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0053] Example 1: Normal use as a hospital bed:

[0054] The fixed bed body 11 and the movable bed wings 12 are located around the stretcher bed body 2 to fix it. The bed boards 13 extending toward the center of the bed from the fixed bed body 11 and the movable bed wings 12 are flush with the edges of both sides of the stretcher bed body 2 to form the entire bed surface structure. At this time, the main bed body 1 of the hospital bed is supported on the ground by the supporting feet under the four corners of the fixed bed body 11, and the movable bed wings 12 are supported on the ground by movable brackets 123. Guardrails are installed at both ends of the bed body. Like ordinary beds, guardrails are installed at the head and tail ends of the bed, and guardrails are also installed on the edges of the fixed bed body 11 and the movable bed wings 12, and can be folded and stored to ensure the movement and safety of patients.

[0055] The main mattress 21 is installed on the stretcher bed 2 through the strapping belt 212 and the crossbeam 211 on the bed board 13 to prevent the main mattress 21 from sliding during the transportation of the patient. The strapping belt 212 and the crossbeam 211 mentioned here can be the mattress fixing holes, tied to the bed board 13 through ropes, or can be adhesive accessories such as Velcro; the main mattress 21 and the mattress flap 22 form the entire mattress, which are connected into one by the mattress sewing zipper. The mattress flap 22 can be removed during transportation according to the patient's needs. The mattress adopts a frame composed of a material that is soft in the horizontal direction and has a certain supporting hardness in the vertical direction, such as flexible steel wire or strip PVC. When the head or foot of the bed is raised, the mattress can adapt well and bring comfort to the patient.

[0056] When the mattress flap 22 is not in use, the mattress flap 22 is flattened and stored, flush with the main mattress 21, to form a complete mattress; at this time, the flap 23 is folded in multiple layers and stored under the mattress flap 22, and the cumulative thickness of the mattress flap 22 and the flap 23 is equivalent to the thickness of the main mattress 21. In this state, the frame 25 is supported by the front guide wheel 251 at the front end and the rear wheel 252 at the rear end.

[0057] Embodiment 2: When the stretcher bed 2 is needed:

[0058] The patient lies on the center of the stretcher bed 2, the movable support 123 is rotated, and the support rotating shaft 124 is lifted to fit the bottom of the movable bed wing 12, and fixed by the fixing component 125, and then the mattress aileron 22 on the movable bed wing 12 is erected to one side of the stretcher bed 2 to form a guardrail-like upright state; then the movable bed wing 12 is manually flipped up, and the movable bed wing 12 is rotated to the upper side along the central axis of the fixed bed 11 under the action of the wing arms 121 at both ends and the movable bed wing rotating shaft 122, and after being fixed and stabilized by the limit block, an exit for the stretcher bed 2 to enter and exit is exposed, and then the rear steering wheel 253 at the end of the frame 25 of the stretcher bed 2 is operated. Lifting to the ground, the upgrade component and control system 3 are both existing technologies, which can be provided by a servo lifting motor or a hydraulic lifting structure, so that the rear wheels 252 can be off the ground. At this time, the stretcher bed body 2 is pulled, and under the lateral sliding of the front guide wheel 251 and the rear steering wheel 253, the stretcher bed body 2 is separated from the fixed bed body 11, and then pushed out of the bed corridor. When it is in the ward corridor, the rear steering wheel 253 can be retracted to make the rear wheels 252 touch the ground, so that the stretcher bed body 2 can be pushed to move;

[0059] During the movement, the larger rear wheels 252 can provide good stability and comfort, and can also cross a certain height threshold; during the transportation of patients, according to the needs of the patients, the mattress flaps 22 can be used to stand upright to provide a guardrail, and the mattress flaps 22 on both sides of the stretcher bed body 2 can be supported and rotated vertically to provide fixation to ensure the safety of the patient. If the mattress flaps 22 are removed to transport the patient, the patient can be fixed with a strap. The flaps 23 on the mattress flaps 22 can also be unfolded, and the flaps 23 on both sides are connected through connecting parts 24, such as zippers, Velcro and other parts to form a cylindrical chamber around the patient, so that the patient is protected from wind and sun during the movement, and the privacy of the patient can also be protected; after arriving at the operating room, the height of the stretcher bed surface 26 can be adjusted by synchronously lifting and lowering the stretcher lifting rod 255 according to the height requirements of the operating bed to meet the height requirements of medical use; or it can be adjusted according to the height of the nursing staff to maintain a comfortable height during the pushing of the stretcher bed 2.

[0060] The stretcher lifting rod 255 is built into the lifting column 254, and the top is directly connected and fixed to at least four corners of the stretcher bed 26. Its lifting function directly makes the stretcher bed 26 keep horizontal and synchronously lift and adjust the height; and the control system 3 keeps the stretcher bed 26 in a horizontal state. At the same time, the lifting column 254 can also adjust the height of the stretcher bed 26 to keep it consistent with the height of the bed board 13 of the main bed body 1 of the hospital bed, or adjust it according to the height of the nursing staff to maintain a comfortable height during the implementation of the stretcher bed 2. It should be noted that the lifting mechanism and the corresponding control system 3 are mature existing technologies. In the present invention, various lifting mechanisms and adapted control systems 3 can be selected for adaptation and installation, such as lifting servo motors, hydraulic and pneumatic lifting mechanisms, and with mature control systems 3, stable and safe lifting control can be achieved. Therefore, the specific lifting structure is not the protection content of the present invention. The control system 3, lifting mechanism and other conventional accessories are installed at the bottom of the frame 25, which can lower the center of gravity of the bed body 2 to ensure that it is stable and does not tip over during use.

[0061] Example 3: When used as a hospital bed in daily life:

[0062] The telescopic top rod 273 can be controlled to retract or retract through the control end, so that the bed surface movable frame 27 of the stretcher bed surface 26 is rotated, pushed up or lowered, so that the upper body movable frame 271 or the lower body movable frame 272 rises or falls: for example, when the patient wants to sit up, the telescopic top rod 273 connected to the upper body movable frame 271 is controlled to extend, and the telescopic top rod 273 pushes the upper body movable frame 271 to rotate upward and stand up, thereby driving the patient's body to stand up and sit up; for example, when the patient wants to bend his legs, the telescopic top rod 273 connected to the lower body movable frame 272 can be controlled to extend, and the lower body movable frame 272 is limited by the structure of the telescopic top rod 273 and the movable frame joint 274, The lower body movable frame 272 is raised in a triangular shape, driving the patient's knee joint to bend at the top of the three-piece shape, and stop at an appropriate height, and the legs are bent; when it is necessary to restore to a normal bed surface, the reverse operation can be performed.

[0063] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
