Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] This embodiment relates to a postpartum abdominal binder, such as... Figures 1 to 2 As shown, the postpartum abdominal binder includes a main belt body 1 and a locking part 2 slidably disposed on the main belt body 1. The main belt body 1 includes a wrapping part 101 located in the middle position and connecting parts 102 disposed at both ends of the wrapping part 101. The locking part 2 includes an elastic band 201 extending along the length direction of the main belt body 1 and locking components 202 disposed on both sides of the elastic band 201.

[0049] The wrapping section 101 is equipped with two sets of airbag 3 assemblies arranged opposite to each other. Each airbag 3 assembly includes several airbags 3 spaced apart along the length of the main strap 1. The airbags 3 are embedded in the wrapping section 101, and the exhaust pressure of the airbags 3 gradually increases from the middle to the end of the wrapping section 101. When the pressure of the airbag 3 reaches its own exhaust pressure, the exhaust port of the airbag 3 releases air.

[0050] In this embodiment of the postpartum abdominal binder, two sets of airbag 3 components are arranged opposite to each other in the wrapping part 101. The airbag 3 is arranged sequentially in the direction from the middle to the end of the wrapping part 101, and the exhaust pressure gradually increases. When the wearer inhales, the wearer pulls the locking part 2 with both hands to wrap the main belt 1 on the abdominal wall tissue. By connecting the connecting parts 102 at both ends together, the main belt 1 is fixed to the body tissue.

[0051] If the main strap 1 is too tight after wearing, the airbag 3 near the center of the wrapping part 101 will first reach the preset decompression pressure to release air. After the airbag 3 is decompressed, it increases the diameter of the main strap 1. If the main strap 1 is too loose, the elastic band 201 will wrap around the outside of the main strap 1 for secondary tightening. The locking component 202 will fix the two ends of the elastic band 201 together, and the main strap 1 and the locking part 2 will achieve an overall abdominal tightening effect. This postpartum abdominal binder can automatically adjust the tightness of the strap to avoid damage to the body due to the abdominal binder being too tight and improve the wearing efficiency.

[0052] Based on the above overall description, this embodiment provides an exemplary structure of a postpartum abdominal binder, such as... Figures 1 to 2As shown, the main band body 1 is long strip-shaped, and its length can be set to multiple specifications according to different people, and the length of the main band body 1 is greater than the waist and hip circumference of the wearer, and the connecting portions 102 on both sides of the main band body 1 are connected by adhesion, and the main band body 1 is wrapped on the human body by connecting the connecting portions 102 at both ends.

[0053] As shown, Figure 1 As shown, the locking portion 2 includes an elastic band 201 and locking assemblies 202 arranged on both sides of the elastic band 201, and as a specific embodiment, the elastic band 201 is arranged as multiple sub-bands and connecting bodies connected on both sides of the sub-bands, so as to reduce the tension of the elastic band 201 when worn and facilitate the connection of the locking assemblies 202. As a preferred embodiment, the locking assembly 202 is a hook 2021 arranged on the connecting body at one end of the sub-band, and a plurality of hook seats 2022 arranged on the connecting body at the other end, and the hook 2021 and the hook seats 2022 of different rows can be connected to fine-tune the connection tension of the elastic band 201.

[0054] In this embodiment, by arranging the locking portion 2 outside the main band body 1, when the person eats or drinks water, the stomach and abdomen are protruding, causing a greater sense of oppression, at this time, the automatic adjustment can be performed by releasing the air bag 3, and only the positions of the hook 2021 and the hook seat 2022 need to be adjusted, without the need to untie the entire abdominal belt, thereby prolonging the service life of the abdominal belt and bringing convenience to the wearer.

[0055] Further, as shown, Figures 1 to 2 The wrapping portion 101 includes two crease portions 1011 arranged at intervals along the width direction thereof, and the crease portions 1011 divide the wrapping portion 101 into a chest wrapping segment 1012, a waist wrapping segment 1013, and a hip wrapping segment 1014 arranged from top to bottom.

[0056] The correct use method of the post-Cesarean section abdominal belt is to push the abdominal belt upward from the abdomen with the palm after tying the abdominal belt, and fix the abdominal belt at the pubic bone to care for the stomach, upper abdomen, and lower abdomen, prevent the occurrence of uterine prolapse and organ downward movement, effectively relieve waist and back pain, and help maintain the function of the uterus and pelvic cavity.

[0057] The method for using the abdominal belt is to place the hand above the pubic symphysis and slowly push the abdominal wall tissue of the lower abdomen upward, first fix the abdominal belt from the pubic symphysis, and bind the abdominal tissue from bottom to top. If the binding belt is only tied around the waist and abdomen, it may push the abdominal organs downward, and over time, it is easy to cause the prolapse of the pelvic organs.

[0058] In this embodiment, by setting two crease parts 1011 in the wrapping part, the wrapping part 101 is divided into a chest wrapping section 1012, a waist wrapping section 1013 and a crotch wrapping section 1014 arranged from top to bottom, and an independent connecting part 102 is arranged in each section, and a matched nylon hook and loop fastener is arranged on each connecting part 102. In this way, it is convenient to wear in sections, adapt to the wearing method of the above-mentioned abdominal belt, and can be adjusted individually according to the uncomfortable parts, thereby improving the wearing efficiency.

[0059] Further, as shown in Figures 1 to 2 , a plurality of support bars 4 are arranged in the waist wrapping part 101, and the support bars 4 are arranged between the two air bags 3. A plurality of support bars 4 are arranged in the waist wrapping part 101, and the support bars 4 are arranged between the two air bags 3. Since the waist wrapping section 1013 has a large curvature, if the elastic band 201 is too tight, the tightening force will be concentrated in a small area, causing discomfort in the local area. Therefore, the support bars 4 are arranged to increase the bearing area of the elastic band 201 on the waist and avoid the concentration of the tightening force due to the elastic deformation of the elastic band 201.

[0060] Preferably, the wrapping part 101 of the present embodiment includes two inner pad layers and a surface layer arranged on both sides of the inner pad layer. A plurality of suture lines 5 connecting the inner pad layer and the surface layer are arranged along the width direction of the wrapping part 101, and a first accommodating space 1015 or a second accommodating space 1016 is formed between two adjacent suture lines 5. The first accommodating space 1015 and the second accommodating space 1016 are arranged alternately. The first accommodating space 1015 is used to accommodate the air bag 3, and the second accommodating space 1016 is used to accommodate the support bar 4.

[0061] Among them, the inner pad layer uses air-permeable sponge or cotton layer as raw material, and the surface layer located on the outer layer is made of cloth layer made of pure cotton, chemical fiber or polyester fiber and the like. As shown in Figure 1 and Figure 2 , the air bag 3 components arranged oppositely in the present embodiment are arranged in the chest wrapping section 1012, the waist wrapping section 1013 and the crotch wrapping section 1014 respectively. The air bag 3 has a rectangular parallelepiped structure, and after inflation, the width of the air bag 3 is reduced, thereby shortening the wrapping diameter, and after deflation, the width of the air bag 3 is increased, thereby lengthening the wrapping diameter.

[0062] Preferably, as shown in Figure 2As shown, the air bag 3 comprises a body 301 for containing gas, and an inflation pipe 302 and an exhaust pipe 303 provided on the body 301, and a gas regulating valve 304 provided on the exhaust pipe 303. The gas regulating valve 304 of the present embodiment is the same as the prior art structure, and will not be described here. The gas regulating valve 304 is used to adjust the exhaust pressure of the air bag 3, and by setting different exhaust pressures, it can be avoided that the adjustment amount is too large due to the simultaneous deflation of multiple air bags 3. The difference in exhaust pressure of each air bag 3 is small, which can be set by actual experience, or adjusted adaptively according to the different bodies of different people.

[0063] In addition, as shown in Figure 2 , the air bags 3 located in the chest wrapping section 1012, the waist wrapping section 1013 and the crotch wrapping section 1014 are provided one by one, and the inlets and outlets of the adjacent air bags 3 are connected, and the exhaust pipe 303 of the air bag 3 located in the chest wrapping section 1012 is exposed outside the wrapping part 101. And the inflation pipe 302 of the air bag 3 is also provided outside the wrapping part 101, so as to facilitate inflation.

[0064] Further, as shown in Figure 1 and Figure 2 , the support bar 4 is provided with an adjusting handle 6, and the adjusting handle 6 is pushed to make the support bar 4 slide in the second containing space 1016. The support bar 4 in the present embodiment is the keel or cartilage in the prior art, which has strong supporting force and can support the waist and back to relieve postpartum back pain. The support bar 4 can be made of plastic with good elasticity. It should be pointed out that the support bar 4 is arranged in a spaced manner with the inflated air bag 3 to form a support on the waist, so as to achieve better support effect and comfort.

[0065] In addition, as shown in Figure 1 and Figure 2 , the length of the support bar 4 is shorter than the length of the waist wrapping section 1013, and in use, the position of the support bar 4 can be adjusted according to the body shape of different people, and the adjusting handle 6 is made of plastic or steel material and is screwed and fixed with the support bar 4. The adjusting handle 6 penetrates the inner pad layer and the surface layer on one side and is exposed outside the main belt body 1, so as to facilitate manual adjustment.

[0066] Further, as shown in Figures 3 to 4 , the body 301 is further provided with a manual pressure relief valve 305, and the exhaust amount of the manual pressure relief valve 305 is smaller than the exhaust amount of the exhaust pipe 303. By providing the manual pressure relief valve 305, the state of the air bag 3 at an uncomfortable position can be adjusted, the gas in the air bag 3 can be fine-tuned, or the air bag 3 at this position can be completely deflated to reduce the tightening force.

[0067] Thus, the wearer can make adaptive adjustment according to his own needs, which is targeted and will not need to re-wear the abdominal belt due to local tightening or discomfort, thereby ensuring the wearing comfort and easy adjustment of the abdominal belt and achieving a better abdominal effect.

[0068] Specifically, as shown in Figure 3 and Figure 4 , the manual pressure relief valve 305 includes a connecting seat 3051 provided on the body 301, a connecting sleeve 3052 screwed on the connecting seat 3051, and an adjusting joint 3053 provided on the connecting sleeve 3052. The connecting seat 3051 is provided with a gas relief channel 3054 communicating with the inner cavity of the body 301, and the adjusting joint 3053 is screwed on the connecting sleeve 3052. The adjusting joint 3053 is correspondingly arranged above the gas relief channel 3054, and when the adjusting joint 3053 is rotated, the adjusting joint 3053 blocks or opens the gas relief channel 3054.

[0069] The connecting seat 3051 is fixedly connected to the body 301 of the air bag 3, and the material of the connecting seat 3051 can be plastic material with good plasticity. The connecting seat 3051 is adhesively fixed to the air bag 3. The connecting seat 3051 is a rotary body circular structure, and the connecting sleeve 3052 is threadedly connected to the connecting seat 3051. As shown in Figure 4 , the upper end of the gas relief channel 3054 is a reverse conical groove structure, and the lower end is a cylindrical groove structure. Correspondingly, the lower end of the adjusting joint 3053 adopts a conical structure, which is matched with the conical groove. When the adjusting joint 3053 is pressed on the conical groove, the gas relief channel 3054 is completely closed. By manually rotating the adjusting joint 3053, the exhaust amount of the air bag 3 can be controlled.

[0070] Further, as shown in Figure 3 and Figure 4 , a gas storage cavity 3055 is arranged between the upper end of the connecting seat 3051 and the connecting sleeve 3052, and a gas relief pipeline 3056 is arranged on the adjusting joint 3053 to communicate the gas storage cavity 3055 with the outside. By arranging the gas storage cavity 3055 and the gas relief pipeline 3056, the exhaust speed of the air bag 3 can be adjusted, which facilitates better control of the exhaust amount of the air bag 3.

[0071] Preferably, as shown in Figure 1 , a plurality of blocking strips 7 are arranged on the side of the wrapping part 101 away from the human body along the width direction of the main belt body 1, and the elastic belt 201 is arranged between the blocking strips 7 and the main belt body 1 to limit the separation of the locking part 2 from the main belt body 1. The blocking strips 7 can also be made of cloth or elastic rubber material. When the locking part 2 is connected to the main belt body 1, the elastic belt 201 can be spacedly covered on the outer side and the inner side of the adjacent blocking strips 7, thereby improving the fixing effect of the locking part 2 and avoiding the locking part 2 from coming out of the main belt body 1.
