The middle airbag support 2-2 is provided with leg airbags 3 respectively towards the left airbag support 2-1 and the right airbag support 2-3. The paired face-to-face arrangement of the airbags 3 allow the airbags to clamp the patient's left and right legs. The leg airbags 3 correspond to patient's legs. The leg airbags 3 will clamp patient's left and right legs when the airbags 3 are inflated with air.

[0039] As shown in FIG. 2, an appropriate space is reserved between the left airbag support 2-1 and the middle airbag support 2-2. An appropriate space is reserved between the right airbag support 2-3 and the middle airbag support 2-2. The legs of the patient are placed in the spaces.

[0040] As shown in FIG. 1 to FIG. 4, chest clamping airbags 14 are arranged on two sides of a position of the table top 1 corresponding to the chest of the patient. Axilla support bars 13 are arranged at positions corresponding to the two axilla of the patient. The chest clamping airbags 14 and the axilla support bars 13 achieve an effect of fixing the upper body of the patient.

[0041] As shown in FIG. 1 to FIG. 4, each leg airbag 3 and each chest clamping airbag 14 are both provided with the air inlet and outlet hose 4.

[0042] In the present disclosure, the leg airbags 3 and the chest clamping airbags 14 can be inflated or deflated through the air inlet and outlet hoses 4.

[0043] As shown in FIG. 1, FIG. 3 and FIG. 5, a fixed support 5 is mounted below the table top 1. The fixed support 5 is fixed to a lower surface of the table top 1. A guide rail 6 is arranged at a portion of the sliding support frame 2 that is in contact with the fixed support 5. The guide rail 6 is connected to the fixed support 5 and the sliding support frame 2 respectively. The guide rail 6 is parallel to a direction of the table top 1. The sliding support frame 2 may move back and forth along the guide rail 6 and the table top 1.

[0044] As shown in FIG. 1, FIG. 3 and FIG. 5, an actuator 7 is mounted below the table top 1. One end of the actuator 7 is connected to the sliding support frame 2. The actuator 7 may extend and retract to push and pull the sliding support frame 2 to move back and forth along the guide rail 6.

[0045] In the present disclosure, a push force from the actuator 7 to the sliding support frame 2 is not greater than 25 kg, so as to avoid lumbar spine injury to the patient caused by extremely high lumbar traction strength to the patient.

[0046] As shown in FIG. 3, the lumbar traction table further includes air pumps 8 and air valves 9. The air pumps 8 are connected to the air valves 9 through the air inlet and outlet hoses 4. The air pumps 8 supply air to the air valves 9 through the air inlet and outlet hoses 4. The air valves 9 are connected to the leg airbags 3 through the air inlet and outlet hoses 4. The leg airbags 3 are inflated, held and deflated through opening, closing and air release functions of the air valves 9, thus forming a complete air loop.

[0047] As shown in FIG. 3, the air valves 9 are connected to the chest clamping airbags 14 through the air inlet and outlet hoses 4. The chest clamping airbags 14 are inflated, held and deflated through the opening, closing and air release functions of the air valves 9, thus forming another complete air loop.

[0048] In the present disclosure, when a patient lays in a supine or prone position on the upper surface of the table top 1, the patient can put one leg in the space between the left airbag support 2-1 and the middle airbag support 2-2 and put another leg in the space between right airbag support 2-3 and the middle airbag support 2-2. The patient clamps the axilla support bars 13 with the axilla. The actuator 7 extends and retracts to drive the sliding support frame 2 to move. The left airbag support 2-1, the middle airbag support 2-2 and the right airbag support 2-3 of the sliding support frame 2 are adjusted to a position where the patient feels comfortable. The air pumps 8 supply air to the air valves 9. The air valves 9 supply air to the leg airbags 3 and the chest clamping airbags 14. After being inflated, the leg airbags 3 swell to clamp the left leg and the right leg of the patient. After being inflated, the chest clamping airbags 14 swell to clamp the chest of the patient. At this time, the actuator 7 pushes the sliding support frame 2 to move towards a direction away from the waist of the patient. The sliding support frame 2 drives the left airbag support 2-1, the middle airbag support 2-2, the right airbag support 2-3 and the leg airbags 3 to clamp the legs of the patient to move towards a direction away from the waist of the patient. The axilla support bars 13 and the chest clamping airbags 14 achieve an effect of fixing the upper body of the patient to prevent the upper body of the patient from moving, thus achieving the lumbar traction for the patient.

[0049] As shown in FIG. 3, the embodiment of the present disclosure is further equipped with a transformer 11. A circuit board 10 is mounted below the table top 1. The transformer 11 is connected to an external power supply. The transformer 11 can be connected to an external power supply socket and convert a high voltage of 110-230 V of the external power supply into a safe voltage lower than 36 V. The transformer 11 is connected with the circuit board 10 through a wire and supplies power to the circuit board 10. The circuit board 10 is connected to the air pumps 8 and the air valves 9 through wires and supplies power to the air pumps 8 and the air valves 9, thus forming a complete power supply loop.

[0050] As shown in FIG. 3, the circuit board 10 is connected to the actuator 7 through a wire. The circuit board 10 supplies power to the actuator 7 through a wire.

[0051] In the present disclosure, the circuit board 10 pre-stores a working program. By means of powering on or powering off the air pumps 8 or the air valves 9 according to the pre-stored program, the circuit board 10 controls the air pumps 8 to pump air or controls the opening, closing and air release of the air valves 9, thus inflating, holding and deflating the leg airbags 3 and the chest clamping airbags 14. The circuit board 10 controls, according to the pre-stored program by means of supplying power to the actuator 7, the actuator 7 to extend and retract.

[0052] As shown in FIG. 1, FIG. 3 and FIG. 5, the lumbar traction table further includes a controller 12. The controller 12 is connected with the circuit board 10 through a wire. The controller 12 is provided with buttons 12-1. The buttons 12-1 are in communication connection with the circuit board 10 through a wire. The circuit board 10 is controlled by means of controlling the buttons 12-1.

[0053] In the present disclosure, when the patient lays in a supine or prone position on the upper surface of the table top 1, the patient can put one leg in the space between the left airbag support 2-1 and the middle airbag support 2-2 and put another leg in the space between right airbag support 2-3 and the middle airbag support 2-2. The patient clamps the axilla support bars 13 with the axilla. The patient operates the buttons 12-1 of the controller 12 to instruct the circuit board 10 to start to work. The circuit board 10 supplies power to the air pumps 8 according to the pre-stored working program, so that the air pumps 8 start to pump air, and the pumped air is conveyed to the air valves 9 through the air inlet and outlet hoses 4. The air valves 9 supply air to the leg airbags 3 and the chest clamping airbags 14. After being inflated, the leg airbags 3 swell to clamp the left leg and the right leg of the patient. After being inflated, the chest clamping airbags 14 swell to clamp the chest of the patient. At this time, the circuit board 10 supplies power to the actuator 7 according to the program, so that the actuator 7 pushes the sliding support frame 2 to move towards a direction away from the waist of the patient. The sliding support frame 2 drives the left airbag support 2-1, the middle airbag support 2-2, the right airbag support 2-3 and the leg airbags 3 to clamp the legs of the patient to move towards a direction away from the waist of the patient. The axilla support bars 13 and the chest clamping airbags 14 achieve an effect of fixing the upper body of the patient to prevent the upper body of the patient from moving, thus achieving the lumbar traction for the patient.

[0054] In the present disclosure, the patient can control an extend-retract length and extend-retract strength of the actuator 7 through the buttons 12-1 of the controller 12, thus controlling a traction length and traction strength.

[0055] In the present disclosure, after the traction is completed, the circuit board 10 stops supplying power to the air valves 9 according to the pre-stored working program, so that the air valves 9 release air to deflate the leg airbags 3 and the chest clamping airbags 14. The leg airbags 3 and the chest clamping airbags 14 are flat after being deflated, and will no longer clamp the legs and the chest of the patient. The circuit board 10 controls, according to the pre-stored working program, the actuator 7 to pull the sliding support frame 2 to move towards the waist of the patient, thus, the sliding support frame 2, the left airbag support 2-1, the middle airbag support 2-2 and the right airbag support 2-3 can be restored to their original positions.

[0056] In the present disclosure, the patient turns on the traction function of the present disclosure through the button 12-1 of the controller 12, and sets a traction distance and traction strength by means of controlling the button 12-1. The circuit board 10 performs traction on the lumbar spine of the patient according to the pre-stored working program and resets the sliding support frame 2, repeatedly for multiple times, to achieve multiple tractions on the lumbar spine of the patient.

[0057] The above descriptions are only the preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements and improvements that are made within the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
