Posture changing auxiliary device for spinal surgery nursing

Technical Field

The invention relates to the technical field of spinal surgery nursing, in particular to a posture changing auxiliary device for spinal surgery nursing.

Background

The spine is formed by connecting 26 vertebrae, is a main beam bone of a human body, supports the weight of the human body, plays a role in protecting nerves, blood vessels and internal organs, and is an important component of the human body. When the spine is fractured, dislocated, unstable and damaged due to various reasons, the problem can be solved only by an operation method. The purpose of the operation is to relieve the pressure on nerves, stabilize and support the spine and restore the normal anatomical relationship of the spine. Because the spine is a bony structure, support and stabilization is only provided by rigid internal fixation. Care is therefore required after spinal surgery. However, since the patient who has performed the spinal surgery is in the rehabilitation process because the body is inconvenient to independently turn, the assistance of an external tool is needed, meanwhile, the patient is forced by tissues on the lying side of the patient due to the long-time lying of the patient, and the blood flow is not smooth, so that the patient needs to be subjected to massage and ventilation treatment, the aggravation of the disease condition of the patient is reduced, the quick rehabilitation of the patient is facilitated, and therefore, the posture change assisting device for the spinal surgery nursing is needed.

arc-shaped block 41 which is fixedly connected with the top end of the second rack bar 17 and is arranged in the sliding rail 46 and is fixedly connected with the outer surface of the second arc-shaped block 45 in the moving process of the second rack bar 17 can slide from the top end of the second arc-shaped block 45 to the top end of the second rack bar 17, so that the top end of the air outlet pipe 38 which is fixedly connected with the top end of the first arc-shaped block 41 can penetrate through the bottom of the movable plate 12 and is positioned in the second groove 33 to be fixedly connected with the massage block 34 to descend, and the first spring 37 which is arranged between the massage block 34 and the lower surface of the third groove 33 and is sleeved on the outer surface of the air outlet pipe 38 is in a stretching state and plays a connecting role initially, thereby facilitating the descent of the massage block 34, when the massage block 34 descends, the connecting rod 26 is restored under the action of the rebound force of the fourth spring 52 by loosening state, and the steel wire rope 10 loses the stress on the second rack bar 17, thereby make the ratch two 17 restore to the throne under the effect of the resilience of spring five 53, and the in-process that the ratch two 17 removed the reset again can extrude the arc piece one 41 through arc piece two 45 and remove and make the arc piece one 41 slide the reset in the slide rail 46 that the arc piece two 45 surface was seted up, just so can make massage piece 34 realize rising and descending at the in-process that pulls repeatedly and unclamp connecting rod 26, and then can massage the sick health position that lies in recess two 33 inside top, thereby promote the circulation of blood and be favorable to the recovery of the state of an illness, and because the meshing of the bottom of spur gear one 19 is connected with ratch three 23, when the ratch two 17 was pulled can drive ratch three 23 through the rotation of spur gear one 19 and move under the inside gliding spacing of spacing groove two 49 through spacing block two 47, then the removal of ratch three 23 can push the piston 21 that the inside sleeve 20 of piston 21 removal promotion sleeve 20 gets into soft air admission through right side fixedly connected with push rod 22 In the tube 18, air in the hose 18 is pushed into the ventilation groove 44 formed in the inner part of the toothed bar II 17 communicated with the hose 18, and meanwhile, the movement of the toothed bar II 17 also enables the arc-shaped block I41 to fall on the top end of the toothed bar II 17, when the arc-shaped block I41 falls on the top end of the toothed bar II 17, the connecting tube 40 in the through groove 42 formed in the arc-shaped block I41 can pop out from the inside of the through groove 42 under the action of the rebounding force of the spring II 39 which is originally in a squeezed state to be attached to the top end of the through hole 43 formed in the upper surface in the ventilation groove 44, so that air can be just led into the connecting tube 40 from the ventilation groove 44 through the through hole 43 and enter the air outlet groove 36 formed in the massage block 34 through the air outlet pipe 38, and finally goes out through the air outlet hole 35, thereby realizing ventilation of the part of the patient body in the groove II 33 and carrying out ventilation along with the massage, thereby being beneficial to reducing the pressure injury of the skin of the patient, improving the comfort of the patient, reducing the pain and accelerating the recovery.
