Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, the present invention includes the first bed body 11 and the second bed body 12 that are hingedly connected, and a PLC controller (not marked) is fixed on the first bed body 11 The third linear motor 110 connected is provided with a slide bar 14 at the bottom of the second bed body 12, and a slide block (15) is sleeved on the slide bar 14, and the output end of the third linear motor 110 is connected to the The sliding block 15 is hingedly connected; one side of the second bed body 12 is provided with an auxiliary sideways device, and the other side is provided with a head fixing mechanism adapted and linked with the auxiliary sideways device, and the auxiliary sideways device and the head The fixing mechanisms are all connected with the PLC controller.

Specifically, the auxiliary sideways device includes a first linear motor 121 and a second linear motor 122 that are both connected to the PLC controller and symmetrically arranged on the second bed body 12. The output end of the first linear motor 121 A first push block 123 is connected to it, and a second push block 124 is connected to the output end of the second linear motor 122 . The second bed body 12 is provided with gaps at positions corresponding to the two push blocks.

The non-connecting ends of the first push block 123 and the second push block 124 are all arc structures on the side facing the axial centerline of the second bed body 12, and the upper end surfaces of the two push blocks are in contact with the second bed body 12. The upper end surface of the upper end surface is on the same horizontal plane; the auxiliary sideways device also includes a placement slot on the second bed body 12 corresponding to the arc structure position of the two push blocks, and a PLC controller is fixed in the placement slot. Connected infrared rangefinder2.

The head fixing mechanism includes a driving motor 3 fixed on the second bed body 12, a connecting rod arranged at the output end of the driving motor 3, and a first pallet 31 and a second pallet 32 fixed on the connecting rod , one side on the second pallet 32 is provided with a positioning plate 33, the other side is provided with an extension spring 34, an adjustment plate 35 is provided on the extension spring 34, and the drive motor 3 and the PLC controller connect.

The first supporting plate 31 is provided with a first groove 301, and the second supporting plate 32 is provided with a second groove 302; the first supporting plate 31 is provided with a fixing belt 311, so An eye mask 312 is provided on the fixing belt 311 .

Handrails 120 are provided on the first bed body 11 ; straps 13 are provided on the second bed body 12 .

The using method of the present invention is as follows:

As shown in Figures 1 and 4, before use, the infrared range finder 2, the driving motor 3, the first linear motor 121, the second linear motor 122 and the third linear motor 110 are all connected to the PLC controller, and the first The distance change value between the outer wall of the circular arc structure of the first push block 123 and the second push block 124 and the infrared range finder 2 is preset correspondingly with the rotation angle of the corresponding drive motor 3, so that the patient turns over when the push block is driven , the drive motor 3 can drive the patient's head and neck to rotate adaptively at the same time. For ease of setting, it is advisable for the drive motor 3 to select a stepping motor.

When in use, first pull the adjusting plate 35, the patient lies down, the patient’s neck is located at the position of the second groove 302, and one side of the neck sticks to the positioning plate 33, the adjusting plate 35 is loosened, and under the action of the elastic force of the extension spring 34 , the adjustment plate 35 moves back smoothly and fits with the other side of the patient’s neck, because the same side of the positioning plate 33 and the adjustment plate 35 is adjacent to the patient’s chin position, that is, when the patient turns his head by himself, it will block the interference function, that is, to limit the patient’s subjective consciousness of turning the head objectively; and the head is located at the position of the first groove 301, and at the same time, the patient’s lying posture is first adjusted, specifically, the third linear motor 110 is started, due to The output end of the third linear motor 110 is hingedly connected to the second bed body 12, and the second bed body 12 is also hingedly connected to the first bed body 11, so that the second bed body 12 is turned upside down in the counterclockwise direction, or clockwise The direction is turned downwards so as to adjust the height of the operation position and the angle of the patient’s lying position; during this process, with the change of the inclination angle of the second bed body 12, driven by the output end of the third linear motor 3, the sliding The block 15 is adapted to move on the sliding rod 14 .

Then, for the operation position, when the patient is in a normal lying state and it is inconvenient to operate, the head needs to be turned. In the case of a small rotation angle, the PLC controller can independently start the drive motor 3 and drive the first supporting plate 31 and the second The supporting plate 32 rotates synchronously, so that the head and neck can be rotated at a small angle; if the rotation angle is large, take the left rotation as an example, the first linear motor 121 needs to be started, and the first push block 123 is lifted upwards. Among them, the infrared rangefinder 2 detects that the distance between the outer wall of the arc structure of the first push block 123 begins to decrease, and sends the signal to the PLC controller. The controller sends a starting command to the drive motor 3, so that the drive motor 3 drives the first supporting plate 31 and the second supporting plate 32 to rotate synchronously, that is, when the first push block 123 lifts the patient's right side of the body upward, the head and neck also follow it. It rotates adaptively until the rotation is in place; turning to the right is to start the second linear motor 122 to lift the second push block 124 upwards, and the other operations are the same.

It should be noted that, for the sake of the patient's health, local anesthesia is often used in ENT surgery. When turning the body, the handrail 120 can not only prevent the patient's lower limbs from falling out of the bed, but also allow the patient to hold the handrail 120; To fix the patient, it is necessary to use the strap 13 to fix the body, which can also avoid the discomfort caused by the body turning around and pulling the neck; at the same time, the fixing belt 311 presses the patient's head, and at the same time avoids the patient's nervousness due to sensory reactions. Cover the eyes with the eye mask 312, because the area of the eye mask 312 is relatively large, it can also relieve the pressure of the fixing belt 311 on the head.

As shown in Figure 3 and Figure 4, the patient can also realize the operation of turning the head and turning around in the reclining state (the position of the second push block 124 shown in the position of the dotted line in Figure 4), the operation angle can be adjusted flexibly, and is practical powerful.
