Figure 1 The head support 35 is preferably arranged in the middle position of the left short side of the support base plate 31, so that the patient 6 can lie in the middle position of the support base plate 31. The head support 35 is used to support the head of the patient 6, thereby improving the comfort of the patient 6 lying flat on the support base plate 31, and can also play a positioning support role when the head of the patient 6 needs to be scanned, examined or treated.

[0033] The first end of the support substrate 31 is on both sides of the head support 35 (such as Figure 2The left and right sides of the support base 31 are both provided with front decorative strips 36 for respectively covering the two corners of the first end of the support base 31. That is to say, a front decorative strip 36 is respectively provided on the left and right sides of the head support 35 of the left short side of the support base 31 to cover the two corners of the left short side of the support base 31, thereby filling the installation gap of the head support 35 on the left short side of the support base 31, and at the same time strengthening the support base 31, that is, strengthening the structure of the medical patient support device, thereby improving the service life of the medical patient support device.

[0034] The side edges of the support base plate 31 are provided with side handles 37 and side decorative strips 38 along the length direction thereof, and the side handles 37 are provided close to the headrest 35, that is, the side handles 37 and side decorative strips 38 are provided on the long sides of the support base plate 31, and the side handles 37 can be provided at the front end of the support base plate 31 (such as Figure 1 The left end of the support base 31 is, for example, arranged between the front decorative strip 36 and the side decorative strip 38, so as to facilitate the medical staff to push, pull and lift the support base 31 when operating on both sides; the side decorative strip 38 is arranged on both sides of the support base 31 along the outer circle of the support base 31, so as to strengthen the support base 31 to a certain extent. In order to facilitate the push and pull operation of the support base 31, preferably, the second end of the support base 31 (such as Figure 3 A rear handle 39 is provided at the right end (as shown), which is mainly used to facilitate medical staff to push and pull the support base plate 31.

[0035] Continue to see Figure 2 The rolling assembly 32 includes: two rows of first roller members 321 and a plurality of rows of second roller members 322; wherein the two rows of first roller members 321 are respectively arranged on both sides of the bottom of the supporting substrate 31 along the width direction of the supporting substrate 31 (such as Figure 2The left and right sides shown in the figure); several rows of second roller members 322 are arranged between two rows of the first roller members 321 to provide auxiliary support to the support substrate 31; each row of the first roller members 321 and the second roller members 322 are arranged along the length direction of the support substrate 31. Specifically, the first roller members 321 are installed on the left and right sides of the support substrate 31, and mainly play the role of supporting and rolling transmission of the support substrate 31 to achieve the lateral movement of the support substrate 31. The second roller members 322 can be one row or multiple rows, and there is no limitation on them in this embodiment. Each second roller member 322 is arranged between two rows of first roller members 321, that is, the second roller member 322 is installed near the middle position of the support substrate 31, and plays the role of auxiliary support to the support substrate 31. Preferably, the distance between the bottom end of the second roller member 322 and the bottom wall of the support substrate 31 is smaller than the distance between the bottom end of the first roller member 321 and the bottom wall of the support substrate 31. In an unloaded state or when the weight of the patient 6 carried on the support substrate 31 is less than a threshold value, the first roller member 321 presses against the support sliding base plate 5 so as to contact the support sliding base plate 5 to carry the support device, and there is a gap between the second roller member 322 and the support sliding base plate 5. When the patient 6 lies on the support substrate 31 and his weight reaches the threshold value, the support substrate 31 will deform due to the force. When the deformation reaches a certain extent, the second roller member 322 will contact the support sliding base plate 5 to play an auxiliary supporting role to prevent the support substrate 31 from deforming too much.

Therefore, ceramic material is an ideal material, and other non-metallic high-strength materials can also be used to make the roller shaft; in actual application, if the patient needs to support smooth sliding under heavy load, bearings can be added at the joint installation of the roller and the roller shaft to reduce rolling friction resistance. The roller seat can be fixed to the bottom wall of the support base plate 21 by screws and other connectors, or it can be interference fit in the installation hole opened in the bottom wall of the support base plate 21. This embodiment does not impose any restrictions on it.

[0038] See also Figure 7, which is a schematic diagram of the structure of the support positioning lock provided by an embodiment of the present invention. As shown in the figure, the support positioning lock 34 includes: a positioning lock top pin 341, a handle 342, an eccentric shaft 343, an anti-slip structure 344, and a reset spring 345; wherein the positioning lock top pin 341 is arranged along the thickness direction of the support base plate 31 (such as Figure 7 The handle 342 is rotatably arranged above the positioning lock pin 341; the eccentric shaft 343 is arranged on the handle 342, and the eccentric shaft 343 contacts the top of the positioning lock pin 341 to press the positioning lock pin 341 so that the positioning lock pin 341 moves up and down along the thickness direction of the support base plate 31; the anti-slip structure 344 is at least partially convexly arranged below the positioning lock pin 341 to move with the positioning lock pin 3 41 moves up and down, and when the support base plate 31 slides to a preset position, the anti-slip structure 344 presses against the support sliding bottom plate 5 below the support base plate 31 and rubs against the support sliding bottom plate 5 to lock the support sliding bottom plate 5 and the support base plate 31; the reset spring 345 is sleeved on the outside of the positioning lock top pin 341 and is located between the top of the positioning lock top pin 341 and the top wall of the support base plate 31, so as to push the positioning lock top pin 341 to move upward to reset to a non-locked state.

[0039] The cam 342 is provided with a screw threaded hole 344 at the bottom of the locking cam 341 so that the locking cam 341 and the anti-skid structure 344 can be received in the locking cam 341 when the cam 341 is unlocked. The movable anti-skid structure 344 is pressed against the supporting sliding bottom plate 5 to achieve locking; preferably, the eccentric shaft 343 is rotatably arranged on the handle 342 to reduce the friction between the eccentric shaft 343 and the positioning lock top pin 341; the setting of the reset spring 345 can make the positioning lock top pin 341 move upward to the unlocking state when the handle 342 is rotated to the unlocking state, so as to release the friction lock between the anti-skid structure 344 and the supporting sliding bottom plate 5; to prevent the handle 342 from continuing to rotate after being rotated to the unlocking state, causing its position to be too low and difficult to operate, preferably, a limit piece 347 is provided on the side decorative strip 38 or the supporting base plate 31, which is used to limit the handle 342 in the unlocking state, so that the handle 342 in the unlocking state can only be rotated in the direction of the locking state position; wherein the limit piece 347 can be a positioning pin.

[0040] The locking process of the support positioning lock 34 is as follows: at the preset position, when in the unlocked state, the handle 341 is rotated counterclockwise to drive the eccentric shaft 343 to rotate accordingly, driving the positioning lock top pin 343 to slide downward, and the anti-skid structure 344 is convexly arranged on the outside of the receiving groove and pressed against the support sliding bottom plate 5. The anti-skid structure 344 rubs against the support sliding bottom plate 5 to prevent the lateral sliding of the support base plate 31, and at the same time can play a role in positioning the support base plate 31; in addition, the support positioning lock 34 can meet the medical device Medical regulations require that in an emergency, when not unlocked, the anti-slip structure 344 rubs against the supporting sliding base plate 5, but does not completely prevent the sliding of the supporting base plate 31. The supporting base plate 31 can be dragged out so that the patient can be dragged out of the equipment. The unlocking process of the supporting positioning lock 34 is opposite to the locking operation. When the handle 342 is pressed clockwise to a certain position, the handle 342 will collide and limit with the limit piece 347 installed on the side decorative strip 38 to prevent the handle 342 from being pressed too low and inconvenient to open.
