Description

Electric massage chair for childbirth

Technical Field

The invention relates to the technical field of delivery tools, in particular to an electric massage delivery chair.

Background

Delivery refers to the period and process of separating the fetus from the mother into independent individuals, and can be divided into three delivery processes: the first stage of labor, the ostial dilatation period; second phase, fetal delivery; third labor, the placenta delivery phase.

At present, a lying parturient can select a horizontal parturient body position and a sitting parturient body position during parturition, the horizontal parturient body position mainly has the advantages of facilitating a midwife to observe the fetal condition, facilitating the fetal position conversion, facilitating vacuum suction and the like, but when the parturient lies on the back, the enlarged uterus can press blood vessels, so that the blood volume flowing back to the heart is reduced, the placental blood flow is reduced, the fetal distress and the postpartum blood loss are increased, the plasticity of the pelvis is limited, the birth canal is narrow, the probability of dystocia is increased, and the effect of gravity cannot be utilized, so that the labor process is prolonged; the vertical delivery is a body position more suitable for natural delivery, labor pain of a puerpera can be relieved under the action of gravity, the probability of cesarean delivery and use of obstetric forceps is correspondingly reduced, the labor burst, uterine contraction enhancement and labor shortening of the puerpera are facilitated, the puerpera feels comfortable relatively and is easy to accept, and therefore the sitting type delivery body position is gradually inclined by the puerpera and medical care personnel.

Correspondingly when adopting sitting posture childbirth position, also must use the childbirth chair to maintain lying-in woman's position of sitting, also appeared the manifold childbirth chair of many formulas on the market, however these childbirth chairs do not all possess the massage function, consequently, can't provide the massage for the lying-in woman at the childbirth in-process, slow down lying-in woman's sense of pain.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the delivery chair in the prior art does not have the massage function, so that the problem that pain of a puerpera during delivery cannot be relieved in a massage mode is solved, and an electric massage delivery chair is provided.

The technical scheme adopted by the invention for solving the technical problems is as follows: an electric massage childbirth chair comprises a chair frame, a chair seat and a chair back, wherein the chair seat is fixed on the chair frame, the chair back is arranged on the chair frame and is positioned at the rear side of the chair seat, the front side of the chair seat is provided with a notch for a newborn to fall down, and the chair back is provided with an electric massage mechanism;

the electric massage mechanism comprises a back plate, a motor, a screw rod, a sliding block, a transmission shaft and a plurality of eccentric wheels, wherein the back plate is arranged on a chair back, the motor is fixed on the back plate, the output end of the motor is in transmission connection with the screw rod, the screw rod is rotatably arranged on the back plate, the sliding block is slidably arranged on the back plate, the screw rod is in threaded transmission connection with the sliding block, the transmission shaft is rotatably arranged on the sliding block, the eccentric wheels are eccentrically arranged on the transmission shaft, a gear is fixed on the transmission shaft, a rack is fixed on the back plate, the length direction of the rack is consistent with the axial direction of the screw rod, and the gear is meshed with the rack;

the front surface of the back plate is coated with an outer lining, and the eccentric wheel is positioned between the outer lining and the back plate.

Realize massaging the back of the lying-in woman through setting up electronic massage mechanism on the back of the chair in this scheme, pain when slowing down the childbirth of lying-in woman is felt, and this electronic massage structure utilizes the linkage of transmission shaft and slider, the meshing of rack on epaxial gear of transmission and the backplate in the cooperation, ingenious realization the eccentric block in the rotation, carry out linear displacement in step, make the eccentric block interval progressively bulldoze the back of lying-in woman towards a direction, in fact be exactly carry out the wave formula massage to the back of lying-in woman.

The massage chair has the advantages that the lying-in woman can inevitably incline towards one side when sitting on the chair seat, the contact area of the back of the lying-in woman relative to the chair back is inevitably reduced when the lying-in woman inclines to sit, the massage effect is correspondingly reduced, and further, the middle part of the back plate is rotatably arranged on the chair back, a gap is formed between the back plate and the chair back, springs are arranged at the left end and the right end of the gap, and the two ends of each spring are respectively fixed on the back plate and the chair back;

this scheme then utilizes to rotate the backplate and sets up on the back of the chair, and adopt the spring to maintain the balance of backplate, at this moment, the lying-in woman sits with the slope position of sitting when the seat support, the backplate can be oppressed simultaneously to one side that the lying-in woman leaned on, make the corresponding certain inclination of rotating of backplate, thereby improve the area of contact of the relative backplate of lying-in woman's back as far as, and then with the position of sitting that adapts to the multiple condition, guarantee the massage effect to the lying-in woman, after the outer lining on the backplate breaks away from at the back of lying-in woman, under the effect of spring, the relative.

Furthermore, the back of the outer lining is provided with an inner lining, sponge is arranged between the outer lining and the inner lining, and the eccentric wheel is located between the inner lining and the back plate.
