Description
Technical Field
[0001] The utility model relates to a transport vehicle, in particular to a patient transport vehicle for hospitals. Background Art
[0002] Patients often need to undergo a lot of examinations from admission to discharge after rehabilitation, and the patient needs to be moved during examination or surgery. At present, hospitals use beds with rollers to transfer patients, and patients need to be transferred from the beds in the ward to the beds with rollers. For patients with serious conditions who need to stay in bed, family members need to lift the patient from the original bed to the transfer bed during the transfer process. However, if the patient is accompanied by a female family member, it is generally difficult to complete the process of changing the patient's bed alone. In addition, it is easy to touch the patient's wounds and affected areas during the lifting process, which can easily cause harm to the patient. Frequent examinations and transfers are more likely to cause psychological burdens to the patient. In addition, during the transfer process, two people are generally required, one at the head of the bed and the other at the foot of the bed to push the bed at the same time to control the direction of the bed's movement and prevent the bed from running off the side, which is a waste of manpower.

[0026] The following is a further description of this implementation case in conjunction with the accompanying drawings:
[0027] Depend on Figure 1 — Figure 5 It can be seen that the present application includes a frame 1, which is a frame structure, and the lower part of the frame 1 is fixedly connected with a front axle 110 and a rear axle 120, and wheels 111 are installed on both sides of the front axle 110 and the rear axle 120. The frame 1 is also fixedly connected with a battery 9. In this embodiment, a layer plate 130 is provided on the frame 1, and a battery 9 is fixedly connected above the layer plate 130. The front axle 110 is an electric front axle, and the battery is electrically connected to the motor 112 of the front axle 110; a bed plate portion 2 is provided, and the bed plate portion 2 is slidably connected to the upper part of the frame 1; a first power device is provided, and the first power device drives the bed plate portion to slide along the width direction of the frame 1, so that the bed plate portion 2 can protrude to one side of the frame 1 and overlap on the bed, and a direction control device is provided, and the running trajectory of the transfer vehicle is controlled by the direction control device. In this embodiment, electric is used as the drive, and electric has the characteristics of low noise and the like, which is more suitable for hospital use. This application is mainly aimed at patients with relatively serious conditions, especially those who need to stay in bed. As we all know, after admission, patients need to undergo various examinations frequently for a period of time before and after the operation in addition to being transferred for surgery. Bedridden patients cannot change beds on their own, and generally require nursing staff to change them. In addition, hospital staff generally do not assist in the bed change process, and the patient's family members need to solve it by themselves. Most of the accompanying family members are women, and male patients are generally heavier. The accompanying staff cannot move the patient to the transfer bed by dragging the bed sheets themselves. The bed board part 2 of the transfer vehicle of the present application can be movably overlapped with the bed. When in use, the patient's body can be slightly turned sideways, and the bed board part 2 can be pushed under the patient's turned sideways part for easy movement. Alternatively, the bed board part 2 can be directly inserted between the bed sheet and the bed, and the bed sheet can be dragged to move the patient to the transfer vehicle, and then the bed board part 2 can be returned to its place. The present application not only solves the problem of bedridden patients being difficult to move, but also solves the problem of requiring more than two people to push the bed during the transfer process.
[0028] On the basis of the above-mentioned embodiment, preferably, a crossbeam 140 is provided on the upper part of the frame 1, a slide rail 141 is provided on the crossbeam 140, a slider is connected to the lower part of the bed board part 2, and the bed board part 2 is connected to the frame through the slide rail 141 and the slider, so that the bed board part 2 slides along the slide rail. This embodiment further discloses a connecting component for the bed board part 2 to achieve displacement, and the crossbeam 140 can enhance the load-bearing capacity of the slide rail 141. In this embodiment, in order to ensure the sliding effect, four sets of slide rails 141 are correspondingly provided under the bed board part 2.
[0029] On the basis of the above-mentioned embodiment, preferably, the bed board portion 2 includes a first bed board 210 and a second bed board 220, the first bed board 210 is hinged to the second bed board 220, and a slider is provided at the lower part of the first bed board 210. This embodiment discloses a new structure of the bed board portion 2, which is hinged to the first bed board 210 and the second bed board 220, and enhances the flexibility of the bed board portion 2, because the heights of hospital beds produced by different manufacturers may be slightly different. In this application, the second bed board 220 can be rotated at a certain angle along the hinge point, and even if the heights of the bed board portion 2 and the bed surface of the hospital bed are slightly different, it can be ensured that the second bed board 220 can be overlapped on the bed surface.

The installation of the shield 4 has the following advantages: the guard plate 420 can be made of a frosted surface, etc., which can protect the privacy of the patient to a certain extent. During the current patient transportation process, the patient lies directly on the bed, which may cause the patient to feel embarrassed due to the morbidity during the transportation process. The shield 4 can solve this problem. In addition, after the shield is set, it can also be used to transport patients with infectious diseases, which can reduce the scope of transmission to a certain extent.
