Detailed Implementation

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a patient transport bed with automatic seat belt adjustment function, such as Figure 1-4 As shown, the bed includes a bed frame 1. Bed legs 2 are connected to the bottom of the bed frame 1 near the four corners. A fixed box 9 is connected to the bottom of the bed frame 1 near the center. Guide rods 12 are connected to the inner walls of the left and right sides of the fixed box 9 near the center of the top and bottom sides. Two guide plates 14 are fitted on the two guide rods 12 near the center. Safety belt bodies 5 are connected to the two guide plates 14 near the center of the inner cavity of the fixed box 9 on the side away from the center of the inner cavity. Through slots are opened on the left and right sides of the fixed box 9 near the center. The left side of the safety belt body 5 on the left side penetrates the inner cavity of the adjacent through slot and is connected to a card seat 4. The right side of the safety belt body 5 on the right side also penetrates the inner cavity of the adjacent through slot and is connected to a card head 6. Movable components 3 are provided on the bottom of the bed frame 1 near the left and right sides. Each movable component 3 includes a support plate 31 fitted on the two bed legs 2 near the center of the left and right sides. The inner cavity of the two support plates 31 has a connecting hole that matches the bed legs 2 near the center of the front and rear sides. The inner walls of the two connecting holes on the left and right sides are connected to the side walls of the adjacent bed legs 2 near the center.

[0022] It should be noted that, since the existing patient transport bed has a fixed and non-adjustable safety belt length and poor mobility, in order to solve the problems that occur during the use of the existing patient transport bed, this solution solves the problem of the existing patient transport bed having a fixed and non-adjustable safety belt length and poor mobility by using the cooperation of various components on the fixed box 9 and adding two moving components 3 at the bottom of the bed body 1.

[0023] In a further preferred embodiment of this utility model, such as Figure 1 and2 As shown, each of the two support plates 31 has a drive plate 35 near the center of its top. Each of the two drive plates 35 has several abutment rods 33 near the center of its bottom. The spacing between two adjacent abutment rods 33 is the same. Each of the two support plates 31 has several through holes near the center of its inner cavity. The bottom ends of several abutment rods 33 on the left and right sides penetrate the inner cavity of the adjacent through holes and are all connected to a connecting plate 32. Each of the two connecting plates 32 has casters 34 near the center of its bottom on the front and rear sides. The two casters 34 on the left and right sides are symmetrically arranged with the center of the inner cavity of the adjacent connecting plate 32 as the axis of symmetry.

[0024] In this embodiment, when medical staff use the patient transfer bed to transfer a patient, they first lift the patient onto the bed 1, then insert the locking head 6 into the locking seat 4. Next, the medical staff activates the four electric telescopic rods 36 via an external power source. This causes the two electric telescopic rods 36 on the left and right sides to extend outwards, thereby driving the two drive plates 35 downwards. As the two drive plates 35 move downwards, they can jointly drive the adjacent connecting plates 32 downwards via the three adjacent abutment rods 33. The downward movement of the two connecting plates 32 can then drive the two adjacent casters 34 downwards, allowing the four casters 34 to quickly contact the ground. Medical staff can use the four casters 34 to transfer patients placed on the bed 1 to different wards, thus facilitating the movement of the transport bed. After the bed 1 is moved into the ward, the medical staff can activate the four electric telescopic rods 36 again through an external power source. The four electric telescopic rods 36 retract inward when energized, which drives the two drive plates 35 to move upward. This quickly moves the four casters 34 upward and separates them from the ground, allowing the four bed legs 2 to quickly contact the ground. The bed 1 can then be placed stably on the ward floor by the four bed legs 2, preventing the bed 1 from shifting when transporting patients and thus avoiding problems with the transport operation.

[0025] In a further preferred embodiment of this utility model, such as Figure 1 and 2 As shown, electric telescopic rods 36 are provided on the top of the two drive plates 35 near the front and rear. The two electric telescopic rods 36 on the left and right sides are symmetrically arranged with the center of the inner cavity of the adjacent drive plates 35 as the axis of symmetry. The top of the two electric telescopic rods 36 on the left and right sides are connected to the bottom of the bed 1 near the left and right sides, and the bottom of the two electric telescopic rods 36 on the left and right sides are connected to the top of the adjacent drive plates 35 near the center of the front and rear sides.

[0026] In this embodiment, medical staff activate four electric telescopic rods 36 via an external power source. When energized, the four electric telescopic rods 36 extend outward or retract inward, thereby enabling the two electric telescopic rods 36 on the left and right sides to quickly move the adjacent drive plates 35 downward or upward.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 , 3 As shown in Figure 4, a reset spring 13 is fitted on each of the two guide rods 12 near the center. The two reset springs 13 are arranged symmetrically about the center of the inner cavity of the fixed box 9. The left and right ends of the two reset springs 13 are respectively connected to the adjacent guide plate 14 near the center of the inner cavity of the fixed box 9 near the center of the upper and lower sides.

[0028] In this embodiment, after the medical staff lifts the patient onto the bed 1, they drag the two safety belt bodies 5 to insert the buckle 6 into the seat 4. When the medical staff drags the two safety belt bodies 5, the two guide plates 14 slide to both sides on the two guide rods 12, thereby extending the usable length of the two safety belt bodies 5. This achieves the purpose of adjusting the usable length of the safety belt bodies 5, which is beneficial for the transfer bed to protect patients of different sizes. At the same time, two return springs 13 are connected between the two guide plates 14. When the force on the two return springs 13 disappears, the two return springs 13 begin to contract inward, thereby driving the two guide plates 14 to slide to the adjacent side on the two guide rods 12. This gathers the two safety belt bodies 5, allowing them to fit snugly against the patient.

[0029] In a further preferred embodiment of this utility model, such as Figure 3 and 4 As shown, a speaker 10 is connected to the bottom of the fixed box 9 near the center. Wires 11 are connected to the left and right sides of the speaker 10 near the top center. A first circular hole is opened at the bottom of the fixed box 9 near the center of the left and right sides. The adjacent ends of the two wires 11 pass through the inner cavity of the adjacent first circular hole near the top and are connected to Hall sensors 15. The two Hall sensors 15 are connected to the inner walls of the left and right sides of the fixed box 9 near the bottom center on the side away from the center of the inner cavity.

[0030] In this embodiment, when the range of motion of the two seat belt bodies 5 reaches a predetermined value, the circuit of the speaker 10 is connected, which enables the speaker 10 to emit a sound to remind the medical staff, so that the medical staff can stop dragging the seat belt bodies 5 and avoid damage to the seat belt bodies 5 due to forced dragging.

[0031] In a further preferred embodiment of this utility model, such as Figure 3 and 4 As shown, the two Hall sensors 15 have a common wire 17 connected to the pins on their adjacent sides. The inner cavities of the two guide plates 14 are each provided with a second circular hole near the bottom center. The wires 17 are movably connected to the adjacent second circular holes near their left and right ends. Magnet rings 16 are fitted on the wires 17 near their left and right ends. The adjacent sides of the two magnet rings 16 are respectively connected to the side of the adjacent guide plate 14 away from the center of the inner cavity of the fixed box 9 near the bottom center.

[0032] In this embodiment, when medical personnel drag the two seat belt bodies 5, causing the two guide plates 14 to slide to both sides on the two guide rods 12, the two guide plates 14 can drive the two magnetic rings 16 to move closer to the two Hall sensors 15. At this time, the two Hall sensors 15 are affected by the magnetic force of the two magnetic rings 16, making their internal conduction possible, so that the second wire 17 and the two first wires 11 form a circuit, thereby energizing the speaker 10, causing the speaker 10 to emit a sound to remind the medical personnel. When the speaker 10 emits a sound, it indicates that the range of motion of the two seat belt bodies 5 has reached the predetermined value. At this time, the medical personnel immediately stop dragging the seat belt bodies 5 to avoid damage to the seat belt bodies 5 due to forced dragging, thereby protecting the seat belt bodies 5.

[0033] In a further preferred embodiment of this utility model, such as Figure 1 and 2 As shown, the top of the bed 1 is provided with baffles 8 near the left and right sides. The bottom of each baffle 8 is provided with several support rods 7, and the spacing between two adjacent support rods 7 is the same. The tops of the support rods 7 on the left and right sides are connected to the bottom of the adjacent baffles 8 near the center, and the bottoms of the support rods 7 on the left and right sides are connected to the top of the bed 1 near the left and right sides respectively.

[0034] In this embodiment, by connecting two baffles 8 on both sides of the bed 1, the two baffles 8 can block the patient on both sides of the bed 1, thereby further protecting the patient on the bed 1.
