Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for pregnant women during childbirth, and in particular to a novel hanging belly delivery chair. Background Art

[0002] A pendulous abdomen is a unique abdominal shape during pregnancy, characterized by a noticeable downward and forward bulge in the abdomen, resembling a "pointed belly" or "pendulous" shape. This condition may be accompanied by symptoms such as increased pressure on the lower back and back, and a feeling of skin stretching. The formation of a pendulous abdomen is often related to fetal position, uterine shape, amniotic fluid volume, and the maternal body shape. It should be noted that for pregnant women with a pendulous abdomen, insufficient abdominal muscle strength can easily cause the fetus to misalign with the pelvic axis, making it difficult for the fetus to enter the pelvis.

[0003] Among them, the patent number is: ZL202420974680.6, and the patent name is: A Chinese utility model patent for a gynecological and obstetric delivery chair, which specifically discloses the following technical solutions: A gynecological and obstetric delivery chair, including a main body mechanism and a backrest mechanism.

DETAILED DESCRIPTION

[0027] The present invention will be described below with reference to specific embodiments.

[0028] Example 1, as Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6 As shown, a new type of hanging belly delivery chair includes a bottom bracket 1, a support seat 2 for supporting the buttocks of a pregnant woman when in use, and a support backboard 3 for supporting the back of a pregnant woman when in use. The support seat 2 and the support backboard 3 are respectively installed on the bottom bracket 1.

[0029] Among them, Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 as well as Figure 6 As shown, a bracket bottom frame 11 is provided at the lower end of the bottom bracket 1, and the bracket bottom frame 11 includes a bottom frame front end cross bar 111 and a bottom frame rear end cross bar 112 which extend horizontally along the left and right directions respectively, and the bottom frame front end cross bar 111 and the bottom frame rear end cross bar 112 are arranged at intervals in front and back; two bottom frame arc-shaped legs 113 which are arranged at intervals in the left and right directions and are respectively curved in an arc shape are installed between the bottom frame front end cross bar 111 and the bottom frame rear end cross bar 112, and the front end of each bottom frame arc-shaped leg 113 is respectively connected to the bottom frame front end cross bar 111, and the rear end of each bottom frame arc-shaped leg 113 is respectively connected to the bottom frame rear end cross bar 112.

[0030] Further, such as Figure 1 、 Figure 2 as well as Figure 5As shown, the front end portion of the bracket base frame 11 is provided with two seat support arms 12 that are arranged opposite to each other at intervals on the left and right and extend upward respectively, and the upper end portion of each seat support arm 12 is hinged to the support seat 2 through a first pivot 41; the rear end portion of the bracket base frame 11 is provided with two back panel support arms 13 that are arranged opposite to each other at intervals on the left and right and extend upward respectively, and the upper end portion of each back panel support arm 13 is hinged to the support back panel 3 through a second pivot 42.

[0031] Furthermore, Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6 As shown, a seat adjustment block 51 is installed below the rear end of the supporting seat 2, the seat adjustment block 51 is located on the rear end side of the seat support arm 12, and the rear end of the supporting seat 2 abuts against the upper end of the seat adjustment block 51; a backboard adjustment block 52 is installed below the front end of the supporting backboard 3, the backboard adjustment block 52 is located on the front end side of the backboard support arm 13, and the front end of the supporting backboard 3 abuts against the upper end of the backboard adjustment block 52; the seat adjustment block 51 and the backboard adjustment block 52 are respectively installed on the bottom bracket 1 for horizontal sliding back and forth, and the bottom bracket 1 is equipped with a driving assembly 6, which is used to drive the seat adjustment block 51 and the backboard adjustment block 52 to move synchronously in opposite directions.

[0032] In addition, if Figure 1 、 Figure 3 、 Figure 5 As shown, a vertically penetrating crossbar internal threaded hole 114 is respectively provided in the middle of the front end crossbar 111 of the bottom frame and the middle of the rear end crossbar 112 of the bottom frame, and a vertically arranged adjusting screw 71 is respectively screwed into each crossbar internal threaded hole 114. The lower end of each adjusting screw 71 extends to the lower end side of the corresponding front end crossbar 111 of the bottom frame and the rear end crossbar 112 of the bottom frame, and a pad 72 is installed at the lower end of the adjusting screw 71.

[0033] It should be explained that the front cross bar 111 of the bottom frame, the rear cross bar 112 of the bottom frame, the arc-shaped support legs 113 of the bottom frame, the seat support arms 12, and the back support arms 13 of the present embodiment are an integrated structure, and the bottom bracket 1 of the present embodiment can be a metal bracket structure.

[0034] During use of the new type of hanging belly delivery chair of the first embodiment, a pregnant woman with a hanging belly sits on the new type of hanging belly delivery chair in a reclining position, with her buttocks resting on the supporting surface of the seat support 2 and her back resting on the supporting surface of the back support 3. The normal direction of the supporting surface of the seat support 2 faces upward and rearward, while the normal direction of the supporting surface of the back support 3 faces forward and upward. Since the seat adjustment block 51 is located at the rear end side of the seat support arm 12, and the rear end of the seat support 2 rests on the upper end of the seat adjustment block 51, the seat adjustment block 51 cooperates with the seat support arm 12 to fix the seat support 2. Similarly, since the back support block 52 is located at the front end side of the back support arm 13, and the front end of the back support 3 rests on the upper end of the back support block 52, the back support block 52 cooperates with the back support arm 13 to fix the back support 3.

[0035] It should be noted that during use of the new type of hanging belly delivery chair in the first embodiment, the bottom bracket 1 contacts the ground through the two bottom frame curved legs 113 of the bracket bottom frame 11. The curved bottom frame curved legs 113 can cause the entire bottom bracket 1 to rock. When a pregnant woman with a hanging belly sits on the new type of hanging belly delivery chair in a reclining position, medical staff or the pregnant woman's family members rock the new type of hanging belly delivery chair. At this time, the pregnant woman's body can rock along with the new type of hanging belly delivery chair. During this process, the fetus in the pregnant woman's belly will also rock, and the rocking can promote fetal movement and facilitate fetal position adjustment. In addition, during the process of assisting delivery with the new type of hanging belly delivery chair in the first embodiment, the rocking action can reduce the pain of the pregnant woman during delivery, which can provide a comfortable delivery process for the mother and facilitate the descent or rotation of the fetus in the pelvis, speeding up the delivery process and promoting natural delivery.

[0036] It should be emphasized that the seat adjustment block 51 and the backboard adjustment block 52 of the present embodiment move synchronously in opposite directions under the driving action of the drive assembly 6; when the seat adjustment block and the backboard adjustment block 52 move synchronously close to each other, the seat adjustment block 51 moves backward relative to the bottom bracket 1, and the backboard adjustment block 52 moves forward relative to the bottom bracket 1. The seat adjustment block 51 moving backward will push the rear end of the supporting seat plate 2 to deflect upward, and the backboard adjustment block 52 moving forward will push the front end of the supporting back plate 3 to deflect upward. When the seat adjustment block 51 and the back adjustment block 52 move away from each other synchronously, the seat adjustment block 51 moves forward relative to the bottom bracket 1, and the back adjustment block 52 moves backward relative to the bottom bracket 1. The seat adjustment block 51 moving forward will cause the rear end of the seat support 2 to deflect downward, and the back adjustment block 52 moving backward will cause the front end of the back support 3 to deflect downward. At this time, the angle between the seat support 2 and the back support 3 becomes smaller. Therefore, this embodiment 1 can adjust the angle between the seat support 2 and the back support 3 by driving the seat adjustment block 51 and the back adjustment block 52 by the drive component 6. That is, this embodiment 1 can adaptively support the angles of the seat support 2 and the back support 3 according to the degree of body curvature and comfort requirements of pregnant women with overhanging abdomens, and has good adjustability.

[0037] It should be further emphasized that during the use of the new type of hanging belly delivery chair in the first embodiment, medical staff or the family of the pregnant woman can rotate the adjustment screw 71 of the front cross bar 111 and the rear cross bar 112 of the bottom frame to adjust the height position of each pad 72, and then adaptively adjust the shaking amplitude of the new type of hanging belly delivery chair. It should be pointed out that when the new type of hanging belly delivery chair is shaken to the extreme position, the front pad 72 or the rear pad 72 contacts the ground to achieve the role of limiting. In addition, when shaking is not required, medical staff or the family of the pregnant woman can rotate the adjustment screw 71 of the front cross bar 111 and the rear cross bar 112 of the bottom frame to make each pad 72 press against the ground respectively, so as to fix the entire delivery chair, thereby improving the safety of use.

[0038] In summary, it can be seen that, through the above structural design, the new type of hanging belly delivery chair in the first embodiment has the advantages of novel structural design and good adjustability, and can be effectively used for adjusting the fetal position of pregnant women with hanging abdomen.

[0039] Example 2, as Figure 1 、 Figure 2 as well as Figure 5As shown, the difference between this embodiment 2 and embodiment 1 is that: the bottom bracket 1 also includes two guide rails 14 arranged at intervals opposite to each other on the left and right and extending horizontally along the front and rear directions, each guide rail 14 is respectively located between the seat support arm 12 and the back support arm 13 on the same side, the front end of each guide rail 14 is respectively connected to the corresponding seat support arm 12, and the rear end of each guide rail 14 is respectively connected to the corresponding back support arm 13; the seat adjustment block 51 is respectively provided with a first guide groove 511 corresponding to each guide rail 14, and the seat adjustment block 51 is slidably installed on the guide rail 14 through the first guide groove 511; the back adjustment block 52 is respectively provided with a second guide groove 521 corresponding to each guide rail 14, and the back adjustment block 52 is slidably installed on the guide rail 14 through the second guide groove 521.

[0040] It should be explained that, through the cooperation of the first guide groove 511 and the guide rail 14, the seat plate adjustment block 51 of the second embodiment can accurately move horizontally forward and backward relative to the bottom bracket 1. Similarly, through the cooperation of the second guide groove 521 and the guide rail 14, the back plate adjustment block 52 of the second embodiment can accurately move horizontally forward and backward relative to the bottom bracket 1.

[0041] The bottom bracket 1 of the second embodiment is designed as an integrated structure, and the guide rail 14 , the seat support arm 12 , and the back support arm 13 of the second embodiment are also designed as an integrated structure.

[0042] Example 3, as Figure 1 、 Figure 3 、 Figure 5 as well as Figure 6 As shown, the difference between the third embodiment and the second embodiment is that the bottom bracket 1 also includes a front auxiliary cross bar 151 located between the two seat support arms 12 and a rear auxiliary cross bar 152 located between the two back plate support arms 13. The two ends of the front auxiliary cross bar 151 are respectively connected to the seat support arms 12 on the corresponding side, and the two ends of the rear auxiliary cross bar 152 are respectively connected to the back plate support arms 13 on the corresponding side.

[0043] Among them, the driving component 6 includes a bidirectional driving screw 61 extending horizontally along the front and rear directions. The front end of the bidirectional driving screw 61 is rotatably installed on the front auxiliary cross bar 151 through a bearing, and the rear end of the bidirectional driving screw 61 is rotatably installed on the rear auxiliary cross bar 152 through a bearing.

[0044] In addition, the seat adjustment block 51 is screwed with a front end screw nut 62 corresponding to the bidirectional drive screw 61, and the back plate adjustment block 52 is screwed with a rear end screw nut 63 corresponding to the bidirectional drive screw 61. The front end screw nut 62 cooperates with the front end threaded portion of the bidirectional drive screw 61, and the rear end screw nut 63 cooperates with the rear end threaded portion of the bidirectional drive screw 61.

[0045] It should be noted that, in order to facilitate the rotation operation of the bidirectional driving screw 61, as shown in FIG. Figure 3、 Figure 5 as well as Figure 6 As shown, a screw driving hand wheel 64 is installed at the rear end or the front end of the bidirectional driving screw 61 .

[0046] In the process of driving the seat adjustment block 51 and the backboard adjustment block 52 to move in the opposite direction synchronously through the driving component 6, the medical staff or the family members of the pregnant woman drive the bidirectional driving screw 61 to rotate through the screw driving handwheel 64, and the rotating bidirectional driving screw 61 drives the front end screw nut 62 and the rear end screw nut 63 to move in the opposite direction synchronously, thereby causing the seat adjustment block 51 and the backboard adjustment block 52 to move in the opposite direction synchronously.

[0047] Example 4, as Figure 3 As shown, the difference between the fourth embodiment and the first embodiment is that a screw driving rod 73 is installed on the upper end of each adjusting screw 71 , and an anti-slip rubber pad 74 is installed on the lower surface of each pad 72 .

[0048] As for the screw driving rod 73 of the fourth embodiment, it can facilitate medical personnel or family members of the pregnant woman to rotate and operate the adjustment screw 71, thereby improving the convenience of operation.

[0049] As for the anti-skid rubber pads 74 installed on the lower surfaces of the pads 72, when there is no need to shake, each pad 72 is pressed against the ground by the anti-skid rubber pads 74 to improve the position stability of the new hanging belly delivery chair.

[0050] Example 5, as Figure 1 、 Figure 2 as well as Figure 5 As shown, the difference between this embodiment five and embodiment one is that: the left end edge and the right end edge of the supporting seat plate 2 are respectively provided with a seat plate hinge portion 21 protruding and extending downward, and the two seat plate hinge portions 21 are arranged opposite each other on the left and right, and each seat plate hinge portion 21 is respectively deviated from the middle position of the supporting seat plate 2 and each seat plate hinge portion 21 is respectively close to the front end edge of the supporting seat plate 2.

[0051] The upper end of each seat support arm 12 is hinged to the corresponding seat hinge portion 21 via a first pivot 41 .

[0052] It should be noted that, since each seat hinge portion 21 is close to the front end edge of the supporting seat 2, this structural design can ensure that the rear end of the supporting seat 2 stably and reliably abuts against the upper end of the seat adjustment block 51.

[0053] Example 6: Figure 1 and Figure 5As shown, the difference between this embodiment six and embodiment one is that: the left end edge and the right end edge of the supporting back panel 3 are respectively provided with a back panel hinge portion 31 protruding and extending downward, and the two back panel hinge portions 31 are arranged opposite each other on the left and right, and each back panel hinge portion 31 is respectively deviated from the middle position of the supporting back panel 3 and each back panel hinge portion 31 is respectively close to the rear end edge of the supporting back panel 3.

[0054] The upper end of each backboard support arm 13 is hinged to the corresponding backboard hinge portion 31 via a second pivot 42 .

[0055] It should be pointed out that since each backboard hinge portion 31 is close to the rear end edge of the supporting backboard 3, this structural design can ensure that the front end of the supporting backboard 3 stably and reliably abuts against the upper end of the backboard adjustment block 52.

[0056] Example 7, as Figure 1 、 Figure 2 as well as Figure 5 As shown, the difference between the seventh embodiment and the first embodiment is that the supporting surface of the seat plate 2 is provided with a soft seat cushion 22 , and the supporting surface of the back plate 3 is provided with a soft back cushion 32 .

[0057] The soft seat cushion 22 and the soft back cushion 32 of the seventh embodiment can improve the comfort of use.

[0058] Example eight, as Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, the difference between the eighth embodiment and the first embodiment is that the left and right ends of the supporting seat 2 are respectively provided with seat armrests 81, and the left and right ends of the supporting backboard 3 are respectively provided with backboard armrests 82.

[0059] Specifically, the support seat 2 is provided with a seat insertion hole 23 corresponding to the seat armrest 81, the seat armrest 81 is inserted into the seat insertion hole 23, and the seat armrest 81 is fastened in the seat insertion hole 23 by a handle screw 83.
