Description

TECHNICAL FIELD

[0001] The utility model relates to a patient chair, in particular to a back puncture operation patient chair. BACKGROUND

[0002] Back puncture operation (thoracentesis operation, lumbar puncture operation, spinal puncture operation, etc.) lacks a special operation chair, and different doctors have different operation methods. There are mainly three operation methods: the first operation method is that the patient reversely sits on the chair back of an ordinary chair. The second operation method is that the patient sits on the bedside of a sickbed, and the relatives of the patient hold or act as a support to let the patient hold or support in front of the patient. The third method is to let the patient lie on a table, and the table is covered with a mattress or a pillow.

[0003] The first operation method is that the patient reversely sits on the chair back of an ordinary chair. This form needs the patient and the doctor to constantly communicate to adjust the sitting posture and the arching angle of the waist and back, and a lot of energy and time of the doctor and the patient are consumed. At the same time, the patient is not supported by the hands, chest and abdomen, and the sitting posture during the operation will be uncomfortable and painful. The second operation method is that the patient sits on the bedside of a sickbed, and the relatives of the patient hold or act as a support to let the patient hold or support in front of the patient. This method also needs the patient and the doctor to communicate a lot to adjust the posture and the arching angle of the waist and back, and if the relatives do not hold firmly, the patient will be injured. This method has a great safety hazard and a medical accident risk. The third method is to let the patient lie on a table, and the table is covered with a mattress or a pillow. This method has the same problem as the first method, and the doctor and the patient need a lot of time to adjust the posture. And because there is an additional table, it is more troublesome to adjust the position.

[0004] The current three main operation methods have defects. The first operation method is that the patient reversely sits on the chair back of an ordinary chair. This form needs the patient and the doctor to constantly communicate to adjust the sitting posture and the arching angle of the waist and back, and a lot of energy and time of the doctor and the patient are consumed. Moreover, the chair has no casters, and it is not convenient for the doctor to move the position of the patient. At the same time, the patient is not supported by the hands, chest and abdomen, and the sitting posture during the operation will be uncomfortable and painful.

[0005] The second operation method is that the patient sits on the bedside of a sickbed, and the relatives of the patient hold or act as a support to let the patient hold or support in front of the patient. This method also needs the patient and the doctor to communicate a lot to adjust the posture and the arching angle of the waist and back, and if the relatives do not hold firmly, the patient will fall and be injured. This method has a great safety hazard and a medical accident risk.

[0006] The third way is to let the patient lie on a table, and the table is covered with a mattress or a pillow. This way has the same problem as the first way, and the doctor and the patient need a lot of time to adjust the posture.
