Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic examination beds, and specifically, to a bed for gynecological ultrasonic examination. Background Art

[0002] A bed for gynecological ultrasonic examination, also known as a gynecological ultrasonic diagnosis and treatment bed or a gynecological ultrasonic detection bed, is a medical device specifically used for gynecological ultrasonic examination. The design of this bed fully considers the needs of gynecological ultrasonic examination and has various functions and characteristics to ensure the smooth progress of the examination and the comfort of patients.

[0003] After retrieval, a Chinese patent with the publication number CN119385793A discloses a gynecological examination bed with an extension function, including a moving seat. The upper surface of the moving seat is fixedly connected with a support seat, and the top of the support seat is fixedly connected with a main body of the examination bed. A leg support adjustment seat is arranged on the front side of the main body of the examination bed. In the above solution, after the patient's legs are placed on the leg support pad, the leg support pad is rotated along the hinge joint of the leg support adjustment seat and the movable connection seat, facilitating the patient to open and place the legs. The patient can place the feet on the pedal to avoid discomfort caused by the feet hanging in the air or having no support. The pedal moves forward, thereby changing the placement position of the patient's feet, being applicable to patients of different heights, improving the applicability of the device. The pedal can rotate on the rotary connection seat to change the placement angle of the patient's feet and adapt to the patient's habits, further improving the comfort of the examination. However, when the above solution is actually used, there are still the following deficiencies: The gynecological examination bed proposed in the above solution has two major drawbacks when in use: one is that medical staff need to lay a disposable spacer before each examination to prevent cross-infection. This additional operation increases the work complexity and brings inconvenience to the use of the examination bed; the other is that when the patient gets on the examination bed, since they need to sit sideways and twist their bodies to straighten their postures, the cushioning material laid during this process is prone to positional deviation and wrinkling, affecting the isolation effect of the cushioning material.

[0004] Based on this, the present invention discloses a bed for gynecological ultrasonic examination. Summary of the Invention

The collar is fixedly sleeved on the cross bar, and the collar and the limiting cylinder are connected by a fourth spring.

[0013] As a further improvement of the present technical solution, the bottom of the groove has an arc surface that is compatible with the rotating rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. A carrier plate is installed on the bed, equipped with a bedding unit and a winding unit. Medical staff can use these two units to quickly lay clean disposable bedding on the carrier plate. When replacing new bedding, medical staff turn the hand wheel to drive the rotating rod and winding roller to rotate, so that the old bedding can be rolled up and the new bedding can be automatically extended to the carrier plate. The operation is convenient. The disposable bedding is rolled up on the winding roller after use, effectively avoiding contamination. 2. When the disposable padding on the roller is used up, medical staff can quickly disassemble and replace the roller. During disassembly, pinch the fixing block to separate the clamping column from the fixing tube, and the roller can fall off from the fixing tube, realizing quick disassembly. During installation, similarly pinch the fixing block to retract the clamping column into the groove, align the roller between the fixing tubes, and then release the fixing block. The clamping column pops out and snaps into the fixing tube under the action of the first spring, completing quick installation. This design greatly facilitates the replacement of the roller, improves work efficiency, and reduces maintenance difficulty. 3. When enough disposable mats are wound on the winding roller, medical staff only need to rotate the third mounting bracket to separate it from the rotating rod, and then they can directly pull the rolled mat off the rotating rod, achieving quick removal. The operation is simple and convenient, which greatly improves the replacement efficiency. After removing the mat, loosen the third mounting bracket, and it resets under the action of the first torsion spring. During the reset process, the limit block 1 on the third mounting bracket contacts the limit block 2 on the carrier plate, which plays a limiting role and keeps the third mounting bracket horizontal. At this time, the arc position of the bottom of the slot contacts the rotating rod, supporting the rotating rod and ensuring the horizontality of the rotating rod. This design not only facilitates the rapid replacement of the mat on the winding roller, but also ensures the stability of the rotating rod after replacement, which helps to maintain the normal operation of the equipment. 4. Under the action of the clamping unit, the two clamping strips can jointly press the disposable mat, effectively preventing it from deflecting and wrinkling on the carrier. In specific operation, before rolling up the disposable mat, the medical staff pulls the pull rod, and through a series of transmission components, the two clamping strips are separated from the disposable mat to ensure that the disposable mat can move smoothly; after the clean mat is moved to the carrier, the pull rod is released, and the two rotating pieces are reversed and reset under the action of the second torsion spring, so that the two clamping strips press the disposable mat again to achieve compression and fixation. This design not only avoids unnecessary obstruction of the mat when replacing the mat, ensuring a smooth replacement process, but also can fix the mat in time after it is laid, ensuring the flatness and stability of the mat during use, improving the reliability of the equipment and the inspection effect, and providing better conditions for gynecological examinations; 5. The carrier plate and the bed can rotate relative to each other. When the inspector climbs onto the bed, he or she first sits on the carrier plate and then twists his or her body to adjust the posture. During this process, the carrier plate rotates with the inspector. This design effectively prevents the inspector from exerting force on the disposable mat when twisting his or her body, allowing the disposable mat to rotate synchronously with the inspector, thereby further preventing the disposable mat from shifting or wrinkling, and ensuring the flatness and use effect of the mat. 6. When the carrier plate needs to rotate following the examiner, the medical staff pulls the crossbar, driving the toothed plate to separate from the toothed ring, enabling the shaft rod and the carrier plate to rotate freely. At the same time, the crossbar moves to let the slider disengage from the through-hole. After rotating the crossbar and releasing it, the crossbar resets under the action of the fourth spring, and the slider snaps into the card slot, fixing the positions of the crossbar, slider, and toothed plate to prevent the toothed plate from meshing with the toothed ring again, meeting the rotation requirement of the carrier plate. During the inspection, if it is necessary to fix the position of the carrier plate to prevent the examiner from shaking, the medical staff operates in the reverse direction, causing the slider to slide into the through-hole, and the toothed plate resets and meshes with the toothed ring, restricting the rotation of the toothed ring, shaft rod, and carrier plate. This design can not only make the carrier plate rotate flexibly when the examiner adjusts the posture, avoiding the stress on the disposable cushioning material, but also fix the carrier plate during the inspection to ensure the stability of the inspection, improving the flexibility of the equipment use.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] The present invention provides a bed for gynecological ultrasound examination. Refer to Figures 1 - 16As shown in the figure, it includes a bed body 1, a carrier plate 2, a fixing frame 3 and a shaft rod 4. The fixing frame 3 is of a U-shaped structure. The carrier plate 2 is fixed on the fixing frame 3. The shaft rod 4 is fixed on the bottom surface of the fixing frame 3 and is rotatably installed on the bed body 1. A cushion material unit and a winding unit are arranged on the carrier plate 2. The cushion material unit and the winding unit are respectively arranged at both ends of the carrier plate 2. The cushion material unit includes a sleeve 54 and a disposable cushion material 55. The disposable cushion material 55 is wound around the sleeve 54. The winding unit includes a rotatable winding roller 63. One end of the disposable cushion material 55 is connected to the winding roller 63. When the winding roller 63 rotates, a winding action is performed on the disposable cushion material 55.

[0034] See Figure 1 and Figure 2 As shown in the figure, in the bed for gynecological ultrasound examination proposed by the present invention, a carrier plate 2 is arranged on the bed body 1. A cushion material unit and a winding unit are arranged on the carrier plate 2. The cushion material unit is used to provide a clean disposable cushion material 55, and the winding unit is used to wind the used disposable cushion material 55. Medical staff can quickly lay a clean disposable cushion material 55 on the carrier plate 2 by using the cushion material unit and the winding unit. Specifically, when it is necessary to replace the new disposable cushion material 55, the medical staff can rotate the handwheel on the rotating rod 62 to drive the rotating rod 62 to rotate. When the rotating rod 62 rotates, the winding roller 63 thereon rotates accordingly. During the rotation of the winding roller 63, the disposable cushion material 55 can be wound. When the disposable cushion material 55 is wound by the winding roller 63, the clean disposable cushion material 55 will extend from the sleeve 54 and move onto the carrier plate 2. Therefore, the medical staff can quickly replace the disposable cushion material 55 by rotating the handwheel, and the operation is convenient. The used disposable cushion material 55 is wound on the winding roller 63 to avoid contamination.

[0035] See Figure 5 and Figure 6 As shown in the figure, the cushion material unit further includes two first fixing frames 3, two fixing cylinders 52 and a roller shaft 53. The two first fixing frames 3 are both fixed on the side surface of the carrier plate 2. The two fixing cylinders 52 are respectively fixed on the two first fixing frames 3 and are arranged opposite to each other. The shaft rod 4 is detachably arranged between the two fixing cylinders 52. Grooves 56 are opened at both ends of the shaft rod 4. Slidable clamping columns 57 are arranged in the two grooves 56. The two clamping columns 57 are respectively connected to the corresponding grooves 56 through first springs 58. The mutually remote ends of the two clamping columns 57 extend outside the corresponding grooves 56, and the mutually remote ends of the two clamping columns 57 are respectively clamped into the two fixing cylinders 52. Slide openings 59 are opened at both ends of the roller shaft 53. The two slide openings 59 are respectively communicated with the two grooves 56. Fixing blocks 510 are fixed on the two clamping columns 57. The two fixing blocks 510 respectively slide in the two slide openings 59; For the roller 53, it has a quick-release function. When the disposable padding 55 on the roller 53 is consumed, medical staff can quickly disassemble and replace the roller 53. Specifically, when disassembling the roller 53, the medical staff pinch the two fixing blocks 510 to make the two fixing blocks 510 approach each other. When the two fixing blocks 510 approach each other, they drive the two clamping posts 57 to approach each other until the two clamping posts 57 are disengaged from the two fixing cylinders 52 respectively. Without the restriction of the two clamping posts 57, the roller 53 can fall off between the two fixing cylinders 52, realizing the quick disassembly of the roller 53. Conversely, when installing the roller 53, the medical staff also pinch the two fixing blocks 510 to make the two clamping posts 57 retract into the two grooves 56 respectively. Then, the roller 53 is placed between the two fixing cylinders 52, and the two ends of the roller 53 are aligned with the two fixing cylinders 52 respectively. Finally, the two fixing blocks 510 are released, so that the two clamping posts 57 pop out under the elastic force of the two first springs 58 until the two clamping posts 57 are respectively clamped into the two fixing cylinders 52, realizing the quick disassembly and assembly of the roller 53.

[0036] See Figure 3 and Figure 7 As shown in, the winding unit further includes a second fixing frame 3, a rotating rod 62, a fixing rod 64, a third mounting frame 65, a first limiting block 68 and a second limiting block 69. The second fixing frame 3 is fixed on the side of the carrier plate 2. The two first mounting frames 51, the second mounting frame 61 and the third mounting frame 65 are respectively located at the four corners of the carrier plate 2. The rotating rod 62 is rotatably installed on the side of the second fixing frame 3. The winding roller 63 is fixedly sleeved on the rotating rod 62. The fixing rod 64 is fixed on the side of the carrier plate 2. The third mounting frame 65 is rotatably sleeved on the fixing rod 64. The third mounting frame 65 is connected to the carrier plate 2 through a first torsion spring 66. A slot 67 is formed on the third mounting frame 65. The bottom of the slot 67 has an arc surface adapted to the rotating rod 62. The first limiting block 68 is fixed on the side of the third mounting frame 65. The second limiting block 69 is fixed on the side of the carrier plate 2, and the first limiting block 68 is arranged opposite to the second limiting block 69; The take-up roller 63 also has the function of being easy to replace. When enough disposable pads 55 are wound around the take-up roller 63, the medical staff rotates the third mounting bracket 65 to separate the third mounting bracket 65 from the rotating rod 62. At this time, the medical staff can directly pull down the rolled-up disposable pads 55 from the rotating rod 62, and the disposable pads 55 can be quickly removed. After removing the disposable pads 55, the medical staff releases the third mounting bracket 65, and the third mounting bracket 65 resets under the action of the first torsion spring 66. In addition, a first limiting block 68 is fixed on the third mounting bracket 65, and a second limiting block 69 is fixed on the carrier plate 2. During the reset process of the third mounting bracket 65, the first limiting block 68 will contact the second limiting block 69, and the first limiting block 68 and the second limiting block 69 play a limiting role on the third mounting bracket 65, making the third mounting bracket 65 in a horizontal state. In this state, the arc position at the bottom of the slot 67 just contacts the rotating rod 62, so that the third mounting bracket 65 plays a supporting role on the rotating rod 62 and ensures the levelness of the rotating rod 62.

[0037] See Figure 8 and Figure 9 As shown in

[0038] See Figure 10 and Figure 11 As shown in

[0039] See Figure 12As shown in the figure, the control component includes a second sealing cylinder 91, a second sliding plug 92, a pull rod 94, a connecting pipe 95 and a connecting tube 96. The second sealing cylinder 91 is fixed to the bottom surface of the carrier plate 2. The second sliding plug 92 is hermetically and slidably connected inside the second sealing cylinder 91. A third spring 93 is connected between the second sliding plug 92 and the inner surface of the second sealing cylinder 91. One end of the pull rod 94 is connected to the second sliding plug 92, and the other end of the pull rod 94 extends outside the second sealing cylinder 91. The pull rod 94 is slidably connected to the second sealing cylinder 91. One end of the connecting pipe 95 is communicated with the second sealing cylinder 91. The connecting tube 96 has a U-shaped structure. The two ends of the connecting tube 96 are respectively communicated with the two first sealing cylinders 81. The other end of the connecting pipe 95 is communicated with the middle position of the connecting tube 96; A pressing unit for pressing the disposable cushion material 55 is further provided on the carrier plate 2. Under the action of the pressing unit, the two pressing strips 75 can jointly press the disposable cushion material 55, playing a role in fixing the disposable cushion material 55 and preventing the disposable cushion material 55 from shifting and wrinkling on the carrier plate 2. Specifically, before winding the disposable cushion material 55, the medical staff first pulls the pull rod 94. When the pull rod 94 moves, it can drive the second sliding plug 92 to move. When the second sliding plug 92 moves, it can extract the air in the two first sealing cylinders 81 through the connecting pipe 95 and the connecting tube 96. This causes the two first sliding plugs 82 to move synchronously and approach each other. When the two first sliding plugs 82 move, they can drive the two connecting rods 84 to move. The two connecting rods 84 in turn pull the two rotating pieces 72 through the two connecting ropes 85, causing the two rotating pieces 72 to rotate synchronously in opposite directions. When the two rotating pieces 72 rotate, the two pressing strips 75 also rotate accordingly, causing the two pressing strips 75 to be separated from the disposable cushion material 55. In this case, the two pressing strips 75 no longer press the disposable cushion material 55, allowing the disposable cushion material 55 to move smoothly. After the clean disposable cushion material 55 moves onto the carrier plate 2, the medical staff releases the pull rod 94, causing the two rotating pieces 72 to reverse and reset under the action of the two second torsion springs 73 until the two pressing strips 75 press the disposable cushion material 55 again, playing a role in pressing and fixing the disposable cushion material 55.

[0040] See Figure 13As shown in the figure, a positioning unit is provided on the bed body 1. The positioning unit includes a positioning component and a limiting component. The positioning unit is used to provide positioning for the shaft rod 4. The positioning component includes a sleeve plate 101, a gear ring 102 and a gear plate 103. The sleeve plate 101 is fixedly sleeved on the shaft rod 4. The gear ring 102 is fixedly sleeved on the sleeve plate 101. The gear plate 103 meshes with the gear ring 102. The gear plate 103 has an arc-shaped structure, and a number of teeth adapted to the gear ring 102 are provided on the gear plate 103. The limiting component includes a cross bar 104, a slider 105, a limiting cylinder 106 and a collar 109. The cross bar 104 is fixedly connected to the gear plate 103. The slider 105 is fixed on the cross bar 104. The limiting cylinder 106 is fixed to the side of the bed body 1 through two rod bodies. The cross bar 104 passes through the limiting cylinder 106 and is slidably connected to the limiting cylinder 106. An opening 107 is formed on the inner surface of the limiting cylinder 106. The slider 105 slides in the opening 107. A clamping groove 108 is formed at one end of the limiting cylinder 106 away from the gear plate 103. The shape of the clamping groove 108 is adapted to that of the clamping block. The collar 109 is fixedly sleeved on the cross bar 104. The collar 109 and the limiting cylinder 106 are connected by a fourth spring 110; For the carrier plate 2, it is rotatably installed on the bed body 1 through the shaft rod 4, which enables relative rotation between the carrier plate 2 and the bed body 1. When the inspector gets on the bed body 1, first sit on the carrier plate 2, and then straighten the body by twisting the body. When the inspector twists the body, the carrier plate 2 will rotate. This design can avoid the situation of applying force to the disposable cushion 55 when the inspector twists the body, so that the disposable cushion 55 can rotate synchronously with the inspector, further avoiding the phenomenon of deviation or wrinkle of the disposable cushion 55.

[0041] See Figures 14 - 16As shown, a positioning unit for positioning the carrier plate 2 is further provided on the bed body 1. Specifically, when the carrier plate 2 needs to rotate with the inspector, the medical staff pulls the cross bar 104 to move the cross bar 104. When the cross bar 104 moves, it drives the toothed plate 103 to move until the toothed plate 103 is separated from the toothed ring 102. Without the restriction of the toothed plate 103, the toothed ring 102 can rotate freely, which enables the shaft rod 4 and the carrier plate 2 to also rotate freely. In addition, when the cross bar 104 moves, the slider 105 thereon moves accordingly. When the slider 105 disengages from the through hole 107, the medical staff rotates the cross bar 104 to rotate the cross bar 104, the slider 105 and the toothed plate 103 synchronously. When the slider 105 rotates to a position facing the card slot 108, the medical staff releases the cross bar 104 to reset the cross bar 104 under the action of the fourth spring 110 until the slider 105 is snapped into the card slot 108. In this state, the positions of the cross bar 104, the slider 105 and the toothed plate 103 will be fixed, that is, the toothed plate 103 cannot mesh with the toothed ring 102 again. During the inspection process, the medical staff needs to fix the position of the carrier plate 2 to prevent the inspector from shaking. At this time, the medical staff performs the above operations in reverse to make the slider 105 slide into the through hole 107 again, so that the toothed plate 103 can be successfully reset until the toothed plate 103 meshes with the toothed ring 102 again. In this case, the toothed plate 103 provides a limit to the toothed ring 102, and the toothed ring 102, the shaft rod 4 and the carrier plate 2 cannot rotate.
