A kind of medical treatment tumor radiotherapy low-pressure holding device, including pedestal, it is characterized in that：It is vertical that the pedestal is fixedly connected with support
The bottom end of column, the support post top are fixedly connected with hospital bed, and the support post is passed through by rotary shaft, described rotary shaft one end
It is fixedly connected with turntable, the rotary shaft is described by being separately connected the first spill spin block and the second spill spin block towards opposite screw thread
First spill spin block passes through the second hinged rotation by the hinged hinged first connecting rod of the first rotary shaft, second spill spin block
Hinged second connecting rod of axis, the first connecting rod and second connecting rod pass through third rotary shaft and are hinged on link block
On, the link block upper end is fixedly connected with piston rod, and the piston of the piston rod connection is placed in piston cylinder, the piston cylinder
The conduit of connection passes through the hospital bed and is connected to negative pressure bag, and the negative pressure bag is placed on the hospital bed.
As further limiting for the technical program, setting switch in the conduit.
The advantages of prior art is compared, the utility model and good effect are：The patient of radiotherapy lies low or prostrate is in negative pressure
On bag, turntable is rotated, rotary shaft rotates at this time, and the forward screw thread and reverse thread of rotary shaft drive the first spill spin block and the respectively
Two spill spin blocks move toward one another, while the first spill spin block and the second spill spin block drive one end and the second connection of first connecting rod respectively
One end of bar moves toward one another, so that driving link block to move downward link block drive is fixedly connected with that piston moves downward, at this time
Piston is extracted out the air in Pneumatic bag by piston cylinder, and Pneumatic bag is made to harden to molding shape, and stop rotating turntable, three-dimensional at this time
Laser lamp direct projection gives double labeling on patient skin and negative pressure bag, convenient for contraposition, completes to fix, the utility model will be born
Bag pressing is connected with piston cylinder, avoids the disassembly of negative pressure bag, while being avoided to leak air when separating negative pressure bag and air pump and be led
Deformation is caused, and the utility model structure is simple, facilitates operation, convenient for popularizing, improves the fixed efficiency of radiotherapy.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
As Figure 1-Figure 5, the utility model includes pedestal 7, and the pedestal 7 is fixedly connected with the bottom end of support post 4, institute
It states 4 top of support post and is fixedly connected with hospital bed 2, the support post 4 is passed through by rotary shaft 12, and described 12 one end of rotary shaft is fixed
Turntable 6 is connected, the rotary shaft 12 is by being separately connected the first spill spin block 9 and the second spill spin block 11, institute towards opposite screw thread
The first spill spin block 9 is stated by the hinged hinged first connecting rod 5 of the first rotary shaft 8, second spill spin block 11 passes through hinged
Hinged second connecting rod 13 of second rotary shaft 10, the first connecting rod 5 and second connecting rod 13 are rotated by third
