Description

Technical Field

[0001] The invention relates to the field of medical care, and in particular to a combined tool for assisting pregnant women in free body position and promoting the labor process. Background Art

[0002] Free-position delivery means that during the process of waiting for labor and delivery, the mother is allowed to freely choose a comfortable position, such as lying, walking, standing, sitting, kneeling, lying on the ground, squatting, etc., and through changes in body position, the mother's mental and psychological factors, labor force, birth canal and fetal position and other factors that determine delivery are coordinated to facilitate the smooth progress of delivery. Free-position delivery allows the mother to choose the position she feels comfortable in, which helps to relieve tension and pain during delivery. By adjusting the body position, the mother can more effectively utilize the effect of gravity to promote fetal descent and internal rotation, thereby shortening the delivery process, helping to correct abnormal fetal position, reducing the need for surgical assistance, and thus reducing the cesarean section rate.

[0050] In this embodiment, before use, the air pump 301 is turned on, the fourth solenoid valve 314 is opened, and the first solenoid valve 303, the second solenoid valve 311, the third solenoid valve 313, the inflation check valve 315, the deflation check valve 319 and the fifth solenoid valve 403 are closed. When the patient's height is 155 cm to 160 cm and the weight is 100 kg to 150 kg, the air pressure in the main pipeline 310 is 2.00 × 10 5 Pa~2.50×10 5 Pa, the first gas rod 302 and the second gas rod 317 are extended to raise the stool 102 and the footrest 108 by 40 cm to 45 cm. When the patient is 160 cm to 165 cm tall and weighs 120 kg to 160 kg, the air pressure in the main pipe 310 is 2.20 × 10 5 Pa~2.60×10 5 Pa, the first gas rod 302 and the second gas rod 317 are extended to raise the stool 102 by 45 cm to 50 cm. When the patient is 165 cm to 175 cm tall and weighs 140 kg to 170 kg, the air pressure in the main pipe 310 is 2.40 × 10 5 Pa~2.70×10 5 Pa, the first gas rod 302 and the second gas rod 317 are extended to raise the stool 102 by 50 cm to 60 cm.

After the adjustment is completed, the air pump 301 and the fourth solenoid valve 314 are closed. The taller the patient is, the higher the height of the stool 102 and the footrest 108 are, which is convenient for the patient to maintain a comfortable sitting posture during delivery. When the patient is heavier, the air pressure in the main pipeline 310 is greater, which can support pregnant women to sit safely on the stool 102.

[0051] Furthermore, after the adjustment of the stool 102 and the footrest 108 is completed, the patient can adjust the angle of the chair back 101 according to the lying position or sitting position that suits him / her, turn on the air pump 301, turn on the third solenoid valve 313, close the first solenoid valve 303, the second solenoid valve 311, the fourth solenoid valve 314, the inflation check valve 315, the deflation check valve 319 and the fifth solenoid valve 403, and inflate the second hydraulic pump 304. When the air pressure in the second hydraulic pump 304 is 2.20×10 5 Pa~2.30×10 5 Pa, the angle between the seat 102 and the backrest 101 is 160° to 170°, and when the air pressure in the second hydraulic pump 304 is 2.30×10 5 Pa~2.40×10 5 Pa, the angle between the seat 102 and the backrest 101 is 140° to 160°, and when the air pressure in the second hydraulic pump 304 is 2.40×10 5 Pa~2.60×10 5 Pa, the angle between the seat 102 and the backrest 101 is 120° to 140°, and when the air pressure in the second hydraulic pump 304 is 2.60×10 5 Pa~2.80×10 5 At Pa, the angle between the seat 102 and the chair back 101 is 100° to 120°. When the chair back 101 reaches a comfortable angle, the air pump 301 and the third solenoid valve 313 are closed.

[0052] When the patient is preparing for delivery, the massager 105 can be turned on to massage the patient to promote delivery in order to better exert force. The position of the massage block 106 in the massager 105 can be reasonably adjusted according to the patient's height and the area where the massage is required. The air pump 301 and the second solenoid valve 311 are turned on. The patient's height is 155 cm to 160 cm, and the air pressure in the main pipeline 310 and the pipeline 309 is 1.20×10 5 Pa~1.30×10 5 Pa, push the second piston rod 318 in the second hydraulic rod 308 upward by 5 cm to massage the patient's waist. The patient's height is 160 cm to 165 cm. The air pressure in the main pipeline 310 and the pipeline 309 is 1.40×10 5 Pa~1.60×10 5 Pa, push the second piston rod 318 in the second hydraulic rod 308 upward by 10 cm to massage the patient's waist. The patient's height is 165 cm to 170 cm. The air pressure in the main pipeline 310 and the pipeline 309 is 1.70×10 5 Pa~1.90×10 5Pa, push the second piston rod 318 in the second hydraulic rod 308 upward by 15 cm to massage the patient's waist. The patient's height is 170 cm to 180 cm. The air pressure in the main pipeline 310 and the pipeline 309 is 2.00×10 5 Pa~2.20×10 5 Pa, push the second piston rod 318 in the second hydraulic rod 308 to move upward 20 cm to massage the patient's waist. After adjusting the position of the massage block, close the second solenoid valve 311 and the air pump 301.

[0053] Furthermore, when the patient needs to use the delivery ball 201 to relieve labor pains, adjust breathing, and promote fetal descent, the fourth solenoid valve 314 and the first solenoid valve 303 are opened to reduce the air pressure in the main pipeline 310, the first gas rod 302, and the second gas rod 317 to atmospheric pressure. After the stool 102 and the foot pedal 108 are lowered to the lowest position and reset, the fourth solenoid valve 314 and the first solenoid valve 303 are closed, and the air pump 301 and the inflation check valve 315 are opened to pressurize and inflate the delivery ball 201. The size of the delivery ball 201 can be reasonably adjusted according to the patient's height. When the patient's height is 155 cm to 165 cm, the air pressure in the main pipeline 310 and the delivery ball 201 is 1.5×10 5 Pa~1.8×10 5 Pa, the diameter of the delivery ball 201 is 53 cm to 57 cm, when the patient's height is 165 cm to 175 cm, the air pressure in the main pipe 310 and the delivery ball 201 is 2.0×10 5 Pa~2.3×10 5 Pa, the diameter of the delivery ball 201 is 63 cm to 67 cm, when the patient's height is 175 cm to 185 cm, the air pressure in the main pipe 310 and the delivery ball 201 is 2.5×10 5 Pa~2.8×10 5 When the patient is taller than 100 mm, the diameter of the delivery ball 201 is 73 cm to 77 cm. When the patient is taller, the air pressure in the main pipe 310 and the delivery ball 201 is higher, and the diameter of the delivery ball 201 is larger, so that the delivery ball 201 is suitable for patients of corresponding heights, so that the patient can use it comfortably to assist the patient in free-position delivery. After the delivery ball 201 is adjusted to a size suitable for the patient's height, the air pump 301 and the inflation check valve 315 are closed;

[0054] When the patient needs to use the birthing ball 201 in a sitting position for childbirth, the inflation check valve 315 is opened to inflate all six chambers, and the air valve 209 under the air groove 203 is opened to inflate the air holes in the latex cushion airbag 204, so that the air pressure in the air holes reaches 1.1×10 5 Pa~1.6×10 5 Pa, when the air pressure in the pore is 1.1×10 5Pa, the air pressure in the pore is atmospheric pressure, the latex pad is relatively soft, and the surface of the birthing ball 201 is relatively soft. 5 Pa, the air pressure in the pore is relatively high, the latex pad is stretched, and the surface of the birthing ball 201 is relatively hard. The hardness and elasticity of the surface of the birthing ball 201 can be reasonably adjusted according to the patient's needs to assist the patient in free-position delivery;

[0055] The shape of the birthing ball 201 is changed according to the patient's free position delivery posture:

[0056] When the patient uses the birthing ball 201, the air valve 209 on the first air tube 210 below the first chamber 205, the second chamber 206, the third chamber 207, and the fourth chamber 208 is opened, and the chamber above the birthing ball 201 is inflated. When the air pressure in each chamber reaches the air pressure that matches the body weight, the inflation check valve 315 is closed. After the patient sits on the birthing ball 201, when the force-bearing area of ​​the birthing ball 201 is the fourth chamber 208, the patient sits relatively far back and the back cannot touch the chair back 101. At this time, due to the pressure of the patient, When the patient is in the chair, the gas in the fourth chamber 208 flows out through the air valve 209 on the first air pipe 210 which is connected to the pipe provided with the deflation check valve 319 below the fourth chamber 208, and the inflation check valve 315, the deflation check valve 319, and the third solenoid valve 313 are opened. The fourth chamber 208 is depressed by force and the gas flows out. At the same time, the patient leans against the chair back 101, the chair back 101 is pressed downward, the first piston rod 306 on the first hydraulic rod 304 moves downward, the angle between the chair back 101 and the stool 102 becomes larger, and the patient is convenient to use. The patient leans on the chair, and the gas overflowing from the first hydraulic rod 304 and the fourth chamber 208 flows to the first chamber 205, the second chamber 206 and the third chamber 207 through the main pipe 310 and the inflation check valve 315, so that the delivery ball 201 is inflated and keeps elasticity; when the force-bearing area of ​​the delivery ball 201 is the third chamber 207 and the fourth chamber 208, the patient sits relatively forward and the back cannot contact the chair back 101, and the first pipe leading to the pipe with the deflation check valve 319 below the third chamber 207 and the fourth chamber 208 is opened. The air valve 209 on the air pipe 210 opens the air release check valve 319, the third solenoid valve 313 and the second solenoid valve 311, and the third chamber 207 and the fourth chamber 208 are depressed by force and the gas flows out, and the first piston rod 306 on the first hydraulic rod 304 is extended through the main pipeline 310, and the angle between the chair back 101 and the stool 102 is reduced, which is convenient for the patient to lean on. At the same time, the second piston rod 318 on the second hydraulic rod 308 in the chair back 101 is extended, so that the massage block 106 moves upward to massage the patient;When the force-bearing area of ​​the birthing ball 201 is the second chamber 206, the third chamber 207 and the fourth chamber 208, the patient sits relatively forward and his back cannot touch the chair back 101. The air valve 209 on the first air pipe 210 leading to the pipeline with the deflation check valve 319 below the second chamber 206, the third chamber 207 and the fourth chamber 208 is opened. The deflation check valve 319, the third solenoid valve 313, the sixth solenoid valve 322 and the second solenoid valve 311 are opened. After the second chamber 206, the third chamber 207 and the fourth chamber 208 are depressed by the force, more gas flows out, and the first piston rod 306 on the first hydraulic rod 304 is extended through the main pipeline 310, and the chair back 101 and the stool 102 are connected. The angle between the two ends of the chair back 101 and the massage block 106 becomes smaller, which is convenient for the patient to lean on. At the same time, the second piston rod 318 on the second hydraulic rod 308 in the chair back 101 extends, so that the massage block 106 moves upward to massage the patient. The gas flows to the third gas rod 320 through the sixth solenoid valve 322 and the hose 321, so that the third gas rod 320 extends. The armrest 104 increases with the extension of the third gas rod 320, which is convenient for the patient to support. The height of the chair back 101 and the massage block 106 in the massager 105 can be adjusted according to the patient's use of the delivery ball 201 and the force of the delivery ball 201. The patient can use the delivery ball 201 to massage and relax the patient, and the patient can also lean on the chair back 101 when using the delivery ball 201. ;

[0057] In addition, after the patient's delivery is completed, the delivery tools need to be disinfected. The air pump 301 and the fifth solenoid valve 403 are turned on to inflate the second air pipe 401 so that the air pressure above the disinfecting alcohol in the disinfecting nozzle 402 is greater than the atmospheric pressure, so that the disinfecting alcohol is sprayed out from the disinfecting nozzle to disinfect the delivery tools and ensure the production environment.

[0058] In summary, the present invention changes the air pressure in the pipeline through the air pump 301, pipelines and multiple solenoid valves to make the delivery chair structure 1 rise to a height suitable for the patient, and can adjust the chair back 101 to a suitable angle to cooperate with the patient for delivery. At the same time, the massager 106 can be raised to a suitable height according to the patient's height by utilizing the change in the air pressure in the pipeline to massage the patient's waist, relieve labor pains and relax the body. When the delivery ball 201 is needed, the delivery chair is reset, and the air pressure in the pipeline reaches a suitable value according to the patient's height to inflate the delivery ball 201 so that the delivery ball 201 reaches a diameter that matches the patient's height. In addition, through the latex pad airbag 204 and multiple chambers in the delivery ball 201, the delivery ball 201 can change its hardness, elasticity and shape according to the patient's needs and posture, and at the same time adjust the position of the chair back 101 and the massage block 106 in the massager 105. After the delivery is completed, the air pump 301 is used to pressurize the gas in the pipeline to spray disinfectant alcohol from the disinfection nozzle 402 to disinfect the delivery tools and ensure the delivery environment of the next patient.
