[0027] The present disclosure will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure more complete and to fully convey the concept of the present disclosure to those skilled in the art.

[0028] In the description of this disclosure, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure.

[0029] like Figure 1-5As shown, in at least one embodiment of the transfer bed, it includes: an electric lifting platform 100, the top of which is a top plate 110 that can be controlled to lift, and the bottom of which is a base plate 130 with wheels 120 (commonly universal wheels); a bed board 200, which is fixedly laid on the top surface of the top plate 110; a pad 300, which includes a fixing plate 310 and two turning plates 320, the fixing plate 310 being fixedly laid along the center line of the bed board 200, the two turning plates 320 being laid on both sides of the fixing plate 310, and the side edges of the turning plates 320 being hinged to the side edges of the fixing plate 310; and two electric push rods 400, the base of which is fixed to the bottom of the top plate 110, the push rods passing through both the top plate 110 and the bed board 200, and abutting against the bottom surface of the turning plates 320.

[0030] In use, patients requiring transfer lie supine or prone on the pad 300 of the bed board 200. The height of the entire bed board 200 can be adjusted by raising and lowering the top plate 110 of the electric lifting platform 100 to facilitate patient transport. The turning board 320 is pushed by the electric push rod 400. Because the turning board 320 has a rotating connection, it can lift one side of the patient upwards. Medical staff can then apply force to the lifted side, reducing the physical exertion during turning. To ensure successful turning, the fixing plate 310 should not be too wide, ideally 10-30cm. The turning board 320 and the fixing plate 310 can be hinged using conventional hinges. Notches are cut at the edges of both, and the hinges are installed in these notches in a conventional manner. The electric push rod often has a brake, which allows the turning board 320 to rotate to a suitable angle (e.g., 10-30°) after use, stably maintaining this angle and position conducive to assisting turning.

[0031] A control panel 900 is located at the edge of the bed board 200. This control panel 900 has switches for controlling the electric lifting platform 100 and the electric push rod 400. In this way, the operator can easily control them by simply using the switches, eliminating the need for physically demanding methods such as manual cranking.

[0032] In a more specific embodiment, the electric lifting platform 100 is a scissor lift platform, which has an electrically controlled scissor mechanism between the top plate 110 and the bottom plate 130. A scissor mechanism (scissor lifting mechanism) is a mechanical device that achieves vertical lifting through the extension and retraction of a linkage mechanism. It is widely used in aerial work platforms, logistics conveying, industrial equipment, and other fields. This structure is a mature existing technology in the mechanical field, and a common structure is already shown in the accompanying drawings. Specific details will not be elaborated here. To achieve electric control, an electric cylinder can be used to drive the extension and folding of the linkage, thereby controlling the lifting and lowering of the entire platform. Furthermore, an electric cylinder with a braking function or other structure can be used to maintain the platform in its raised or lowered position.

[0033] In a more specific embodiment, the bed board 200 is provided with guardrails 210 on both sides. Each guardrail 210 includes several vertically arranged vertical rods 211 and horizontal rods 212 fixedly connected to the tops of all the vertical rods 211. Several vertically extending first sleeves 220 are provided at the edge of the bed board 200. The vertical rods 211 are fitted into the first sleeves 220, and first screws 221 are screwed to the side of each first sleeve 220 to secure the vertical rods 211 within the first sleeves 220. The guardrails 210 provide protection and also assist in pushing and pulling the bed during movement. In this embodiment, loosening the first screws 221 allows the entire guardrail 210 to be removed, its height adjusted, and it can also be pushed down and stored under the bed.

[0034] In a more specific embodiment, a handrail 250 is provided at the head of the bed at the top of the bed board 200 to facilitate the pushing, pulling and moving of the entire transfer bed.

[0035] In a more specific embodiment, a resuscitation equipment slot 500 is provided along one side edge of the bed board 200. The resuscitation equipment slot 500 is mainly used to house equipment such as ventilators, defibrillators, and monitors. (See also...) Figure 7 To achieve detachability and ease of installation, the resuscitation instrument slot 500 is fixedly connected to a lower clamping plate 510 and several upper clamping plates 520 near the side wall of the bed board 200. The lower clamping plate 510 and the upper clamping plates 520 are used to support the bottom and top surfaces of the bed board 200 at its edge, respectively. Several n-shaped through slots 240 are also provided at the edge of the top surface of the bed board 200. The upper clamping plates 520 pass through the slots 240 and are screwed to the ends with second screws 521. After unscrewing the second screws 521, the entire resuscitation instrument slot 500 can be removed.

[0036] In a more specific embodiment, an air cushion 600 is laid on the pad 300. The use of the air cushion 600 increases comfort and prevents pressure sores. To accommodate the pad 300 and not hinder turning over, the air cushion 600 can be divided into three parallel parts, and the three parts are laid on the fixing plate 310 and the two turning plates 320 respectively.

[0037] In a more specific embodiment, the bed board 200 is provided with fixation straps 700 for securing the patient. The location and number of fixation straps 700 can refer to the fixation strap configuration of common transport beds. Referring to the accompanying drawings, the fixation straps 700 can be configured in three groups (or three locations), located at the head of the bed, the middle area of ​​the bed, and the foot of the bed, respectively, to secure the patient's body in different positions. Common head restraint devices or appliances can also be provided to better secure the patient.

[0038] In a more specific embodiment, an oxygen cylinder holder 230 is provided on the bottom surface of the bed board 200 at the head position for accommodating oxygen cylinders. The oxygen cylinder holder 230 can be placed horizontally, at an angle, or vertically, and its connection can be achieved by fixing a mounting plate between the side wall and the bottom surface of the bed board 200. Relatively speaking, arranging it with the opening slightly tilted upwards makes it easier to put in and take out the oxygen cylinder, and also prevents the oxygen cylinder from easily slipping or falling off.

[0039] In a more specific implementation, while referring to Figure 5 and Figure 6 The electric push rod 400 includes a base 410 and a push rod 420, and its structure is the same as that of existing conventional electric push rods. The base 410 is equipped with a drive motor as a power source and a transmission component that converts the rotational motion output by the motor into the linear motion of the push rod 420. The push rod 420 can extend and retract under the drive of the drive motor. In order to stably push the turning board 320 to rotate through a certain angle, a connecting plate 430 is fixedly connected between the base 410 and the bottom of the bed board 200. A long strip-shaped force plate 440 is vertically fixed to the front end of the push rod 420, and a reinforcing rib 450 is fixedly connected between the push rod 420 and the force plate 440.

[0040] In a more specific embodiment, the bed board 200 is provided with an IV stand 800 at the top corner of the headboard. The IV stand 800 includes a second sleeve 810 that vertically penetrates and is fixedly connected to the bed board 200, a support rod 820 sleeved within the second sleeve 810, a hook 830 fixed to the top of the support rod 820, and a third screw 840 screwed to the side wall of the second sleeve 810 for fastening the support rod 820. Thus, after loosening the third screw 840, the position of the support rod 820 can be adjusted up and down. After adjusting to a suitable height, the third screw 840 can be tightened again.

[0041] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this disclosure should be within the protection scope of this disclosure.
