DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1-4, a tumor radiotherapy bed comprises a base platform 1, a horizontal bed panel 3 is installed above the base platform 1, a support area is provided on the bed panel 3, wherein the support area can be set in the upper body area of the bed panel for the patient to lie down, so it is most tiring when lying half-side or sideways for a long time, so the main support is on the chest or back, the bed panel 3 is located in the support area and is provided with a plurality of rods 6 distributed in a matrix and vertically arranged, the rods 6 penetrate the bed panel 3, and the rods 6 can slide elastically up and down, the bed panel 3 is installed with a positioning mechanism that can simultaneously position all the rods 6, and in a natural state, the rods 6 protrude from the upper plane of the bed panel 3 and have a travel space for downward movement.

Referring to Figure 1, when there is no patient lying on the bed panel 3, the rod body 6 is at the upper stroke limit position, that is, it has the ability to move elastically downward. For example, when the patient is lying on his side at 45 degrees, as the patient lies down, the rod body 6 is pressed down and moves downward. After the patient lies down, the matrix-distributed rod bodies 6 are pressed down to form the shape of the human back, and then the position of the rod bodies 6 is locked by the positioning mechanism, that is, the relative position of the rod bodies 6 and the bed panel 3 is fixed. At this time, the matrix-distributed rod bodies 6 form a support surface that matches the lying posture of the human body, making the patient more comfortable when lying for treatment, and the device can achieve support for patients in different lying postures, which is practical, convenient and flexible.

As an implementation mode of the positioning mechanism, the positioning mechanism includes a first connecting rod 9 located on the bottom plane of the bed panel 3, the first connecting rod 9 is arranged along the width direction of the bed panel 3, and a second connecting rod 10 perpendicular to the first connecting rod 9 is fixedly connected at both ends, and a plurality of rows of parallel clamping plates 11 are fixedly connected between the two second connecting rods 10, each clamping plate 11 corresponds to a row of rod bodies 6, and a power push-pull member that can make the clamping plate 11 close to or away from the rod body 6 is provided at the bottom of the bed panel 3. When the patient lies down, the first connecting rod 9, the second connecting rod 10, and the clamping plate 11 are controlled by the power push-pull member to move together, so that the clamping plate 11 is close to the outer circumference of the rod body 6, thereby achieving the purpose of positioning all the rod bodies 6 at the same time.

As an embodiment, the power push-pull component includes a threaded shaft 4 arranged along the length direction of the bed panel 3, the threaded shaft 4 is rotatably connected to the bed panel 3, the threaded shaft 4 is threadedly connected to the first connecting rod 9, a rotating handle 5 is installed at the end of the threaded shaft 4, or a rotating motor is installed at the end of the threaded shaft 4, the rotation of the threaded shaft 4 is controlled by the rotating motor or the rotating handle 5, and the pushing and pulling action of the first connecting rod 9 is realized under the action of the thread.

In order to make the movement smoother, the first connecting rod 9 is slidably connected to the bed panel 3, and the sliding direction is set along the length direction of the threaded shaft 4; and/or the second connecting rod 10 is slidably connected to the bed panel 3, and the sliding direction is set along the length direction of the threaded shaft 4.

An arc groove is provided on one side of the clamping plate 11 close to the rod body 6 of the corresponding row, and a rubber pad is installed in the arc groove. The installation of the rubber pad increases the friction between the clamping plate 11 and the rod body 6, so that the clamping plate 11 has a better clamping effect on the rod body 6.

A detachable supporting head 8 is installed at the top of the rod body 6. The supporting head 8 can be a plastic head with a silicone head on the surface, which is soft and comfortable. A thrust spring 7 is sleeved on the rod body 6. The thrust spring 7 is clamped between the supporting head 8 and the top surface of the bed panel 3. The thrust spring 7 makes the rod body 6 be in the upper stroke limit position in a natural state.

A detachable limit head 12 is fixedly connected to the bottom end of the rod body 6 , and the limit head 12 is limited at the bottom of the clamping plate 11 . The setting of the limit head 12 prevents the rod body 6 from being pulled out at will.

The bed panel 3 is mounted on the base platform 1 through adjustable telescopic legs 2, and the height of the bed panel 3 can be adjusted.

The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
