Description

Technical Field

[0001] This invention relates to a nursing bed, and more particularly to a nursing bed for pregnant women with hypertension during pregnancy. Background Technology

[0002] Gestational hypertension is a common complication during pregnancy. In particular, when the condition changes, especially when symptoms such as dizziness, nausea, vomiting, or blurred vision occur, timely care is needed to prevent the condition from worsening.

[0003] During hospitalization, pregnant women usually rest on a nursing bed while nursing staff provide daily care. When a pregnant woman feels nauseous, she usually vomits into a trash can. After vomiting, the trash can is covered. However, if the vomit remains in the trash can for a long time, it will emit a pungent odor, making the vomit increasingly unpleasant. When the pregnant woman vomits again, the trash can is opened, and the pungent odor wafts out, which can easily make the pregnant woman feel uncomfortable. Summary of the Invention

[0004] To overcome the drawback of pungent odors emanating from trash cans that can easily cause discomfort to pregnant women, this invention provides a nursing bed for pregnant women with hypertension.

[0005] The technical solution is as follows: A nursing bed for pregnant women with hypertension, comprising a bed board, a bed frame, slide rails, sliders, slide plates, connecting blocks, a circular box, a mounting rod, gears, push blocks, a circular cover, a guide plate, a rack, and a moving mechanism. The bed frame is connected to the bottom of the bed board. Two slide rails are connected to the bed board, arranged opposite each other. A slider is slidably connected to the left slide rail, and a slide plate is slidably connected to the right slide rail. Connecting blocks are slidably connected to both the slider and the slide plate. A circular box for receiving vomit is connected to both connecting blocks. A mounting rod is connected to the side of the circular box, and a gear is rotatably connected to the mounting rod. There are three gears, each connected to a pusher and a round cover. The round cover rotates and enters the round box through the inlet and outlet. The bottom of the bed board is connected to a guide plate, on which three racks are slidably connected. The length of the three racks increases sequentially from top to bottom. As the gears move backward, they mesh with the racks. Then the gears roll on the racks, causing the round cover to rotate and enter the round box, covering it. Then the pusher contacts the racks and pushes the racks to the right, disengaging the racks and gears. The moving mechanism is used to move the round box under the bed board.

[0006] Furthermore, the moving mechanism includes a lead screw and a stepper motor. Lead screws are rotatably connected inside the slide rails. The two lead screws are driven by a belt assembly. The slider and the lead screw on the left side are connected by a thread, and the slide plate and the lead screw on the right side are connected by a thread. A stepper motor is connected to the bed plate. The output shaft of the stepper motor is connected to the lead screw on the left side. The output shaft of the stepper motor drives the lead screw to rotate. The lead screw drives the slider and slide plate to move backward, moving the circular box under the bed plate.

[0007] Furthermore, it also includes a reset mechanism, which includes a reset block, a movable frame, and a spring. Three reset blocks are slidably connected to the guide plate. The reset blocks are used to push the rack to move to the left to reset the rack. The movable frame is slidably connected to the guide plate and is connected to the reset blocks. A spring is connected between the guide plate and the movable frame, and the movable frame is reset by the spring.

[0008] Furthermore, it also includes an automatic mechanism, which includes a wedge block and a push plate. The wedge block is connected to the moving frame, and the push plate is connected to the mounting rod. As the push plate moves backward, it contacts the wedge block and pushes the wedge block to the left. The wedge block drives the moving frame and the reset block to the left. The reset block pushes the rack to the left, so that the rack is reset.

[0009] Furthermore, the side of the pusher plate facing the wedge block is an inclined plane, and the pusher plate moves backward to push the wedge block to the left through the inclined plane.

[0010] Furthermore, it also includes a support mechanism, which includes a mounting box, an airbag, an L-shaped plate, a connecting plate, a second spring, and an inflation assembly. The mounting box is connected to the bed board, and the airbag is connected to the bottom of the mounting box. The L-shaped plate is slidably connected inside the mounting box, and the outer wall of the airbag contacts the inner wall of the L-shaped plate. The connecting plate is connected inside the airbag, and the second spring connects the connecting plate and the mounting box. The connecting plate is reset by the second spring. The inflation assembly is used to inflate the airbag with air, causing the airbag to expand. The L-shaped plate blocks the airbag.

[0011] Furthermore, the inflation assembly includes an air pump, an air inlet pipe, a one-way valve, an air outlet pipe, and a valve. The air pump is connected to the bed board, and the air inlet pipe is connected to the air outlet end of the air pump. The air inlet pipe is connected to the bottom of the mounting box and is also connected to the mounting box. The one-way valve is connected to the air inlet pipe. When the air pump is started, it blows air into the airbag through the air inlet pipe, causing the airbag to inflate. Under the action of the one-way valve, the air in the air inlet pipe will not flow back. The air inlet pipe is connected to the air outlet pipe, and the valve is connected to the air outlet pipe. Opening the valve can expel the air in the air inlet pipe and restore the airbag to its original shape.

[0012] Furthermore, it also includes a fixing mechanism, which includes a U-shaped locking block, a spring three and a U-shaped rod. Both the slider and the slide plate are slidably connected to U-shaped locking blocks for locking the connecting block. Both the slider and the slide plate are connected to spring three, which is connected to the U-shaped locking block. Both U-shaped locking blocks are connected to a U-shaped rod.

[0013] The present invention has the following advantages: 1. The present invention provides a bed board for pregnant women to rest on, and the pregnant women can vomit into a round box. The round cover can cover the vomit in the round box, which can prevent the odor of the vomit from spreading, thereby preventing the pregnant women from feeling uncomfortable.

[0014] 2. The push plate moves backward and pushes the wedge block to the left through the inclined plane, thereby driving the reset block to move to the left. The reset block pushes the rack to the left, so that the rack automatically resets, making it more convenient to use.

[0015] 3. When the air pump is activated, air is injected into the airbag through the air intake tube, causing the airbag to inflate. The pregnant woman can lie on her side and rest against the airbag. The airbag supports the pregnant woman, and lying on her side can reduce pressure on the inferior vena cava and the abdominal aorta, making the pregnant woman more comfortable.

Detailed Implementation

[0031] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0032] Implementation method 1: such as Figures 1-7As shown, a nursing bed for pregnant women with gestational hypertension includes a bed board 1, a bed frame 2, slide rails 3, sliders 4, slide plates 5, connecting blocks 6, a circular box 7, a mounting rod 8, a gear 9, a push block 10, a circular cover 11, a guide plate 12, a rack 13, and a moving mechanism. The bed frame 2 is bolted to the bottom of the bed board 1. Two slide rails 3 are bolted to the left side of the bottom of the bed board 1. The two slide rails 3 are arranged opposite each other. A slider 4 is slidably connected in the left slide rail 3, and a slide plate 5 is slidably connected in the right slide rail 3. Connecting blocks 6 are slidably connected to the front of both slider 4 and slide plate 5. A circular box 7 is connected to the front of both connecting blocks 6. 7 is connected to a mounting rod 8 on the right side. Three gears 9 are rotatably connected to the mounting rod 8 at even intervals. Push blocks 10 are connected to the left side of each gear 9, and round covers 11 are connected to the right side of each gear 9. Three inlets and outlets are evenly spaced on the front side of the circular box 7. The round covers 11 rotate into the circular box 7 through the inlets and outlets. A guide plate 12 is bolted to the bottom left side of the bed board 1. The guide plate 12 is located between two slide rails 3. Three racks 13 are slidably connected at even intervals on the front side of the guide plate 12. The length of the three racks 13 increases sequentially from top to bottom. Damping is provided at the connection between the racks 13 and the guide plate 12. The moving mechanism is used to move the circular box 7 to below the bed board 1.

[0033] like Figure 6 and Figure 7 As shown, the moving mechanism includes a lead screw 15 and a stepper motor 16. Lead screws 15 are rotatably connected inside the slide rail 3. The two lead screws 15 are driven by a belt assembly. The slider 4 and the lead screw 15 on the left side are connected by threads. The slide plate 5 and the lead screw 15 on the right side are connected by threads. The stepper motor 16 is bolted to the middle of the left side of the bottom of the bed plate 1. The output shaft of the stepper motor 16 and the rear end of the lead screw 15 on the left side are connected by a coupling.

[0034] Pregnant women can rest on bed board 1 while nursing staff provide daily care. During pregnancy, high blood pressure is common, and women with high blood pressure are prone to vomiting. The pregnant woman can vomit into the circular box 7. After vomiting, the nursing staff controls the output shaft of stepper motor 16 to rotate, driving the left lead screw 15. The left lead screw 15, via a belt assembly, drives the right lead screw 15, causing slider 4 and slide plate 5 to move backward. This, in turn, moves the circular box 7 and gear 9 backward. The lengths of the three racks 13 increase sequentially from top to bottom, so the bottom gear 9 will mesh with the bottom rack 13 first. Damping is provided at the connection between rack 13 and guide plate 12, preventing rack 13 from moving easily. Therefore, the bottom gear 9 will roll on the bottom rack 13, causing the bottom circular cover 11 to rotate. The bottom circular cover 11 rotates into the circular box 7 through the bottom inlet / outlet, filling the circular box 7. The vomit is covered, and then the bottom pusher 10 and the bottom rack 13 will move the bottom rack 13 to the right, causing the bottom rack 13 and the bottom gear 9 to disengage. The bottom round cover 11 stops rotating. When the pregnant woman feels like vomiting again, the nurse controls the output shaft of the stepper motor 16 to rotate in the opposite direction, causing the round box 7 and gear 9 to move forward and move the round box 7 out from under the bed board 1. The bottom rack 13 and the bottom gear 9 disengage, so the bottom gear 9 will not rotate. The bottom round cover 11 covers the vomit in the round box 7, which can prevent the odor of the vomit from spreading, thus preventing the pregnant woman from feeling uncomfortable. At this time, the pregnant woman can vomit onto the bottom round cover 11. Similarly, when the round box 7 moves backward, the middle gear 9 will engage with the middle rack 13, and the middle round cover 11 will rotate into the round box 7 through the middle inlet and outlet, covering the vomit on the bottom round cover 11.

[0035] Implementation Method 2: Based on Implementation Method 1, such as... Figure 8 As shown, it also includes a reset mechanism, which includes a reset block 17, a movable frame 18 and a spring 19. Three reset blocks 17 are slidably connected at even intervals on the front side of the guide plate 12, and the movable frame 18 is slidably connected on the right side of the guide plate 12. The left side of the movable frame 18 is connected to the right side of the reset block 17. Three springs 19 are sleeved on the movable frame 18, and the two ends of the springs 19 are connected to the guide plate 12 and the movable frame 18 respectively.

[0036] like Figure 8 As shown, it also includes an automatic mechanism, which includes a wedge block 20 and a push plate 21. The wedge block 20 is connected to the lower front side of the moving frame 18, and the push plate 21 is connected to the middle right side of the mounting rod 8. The side of the push plate 21 facing the wedge block 20 is inclined. The push plate 21 moves backward and pushes the wedge block 20 to the left through the inclined surface.

[0037] When there is vomit on the central round cover 11, it indicates that the round box 7 is full of vomit. Control the output shaft of the stepper motor 16 to rotate in the reverse direction, causing the round box 7 to move backward. The push plate 21 will also move backward. The push plate 21 moves backward and pushes the wedge block 20 to move to the left through the inclined plane. The wedge block 20 drives the moving frame 18 and the reset block 17 to move to the left. The spring 19 is compressed, and the reset block 17 pushes the rack 13 to move to the left, so that the rack 13 automatically resets, making it more convenient to use. Then control the output shaft of the stepper motor 16 to rotate, causing the round box 7 to move forward. The gear 9 will also move forward. When the gear 9 moves forward and meshes with the rack 13, the gear 9 rolls on the rack 13. The gear 9 drives the round cover 11 to rotate in the reverse direction, and the round cover 11 rotates out of the round box 7.

[0038] like Figures 9-12 As shown, it also includes a support mechanism, which includes a mounting box 22, an airbag 23, an L-shaped plate 24, a connecting plate 25, springs 26, and an inflation assembly. The mounting box 22 is embedded in the rear of the bed board 1. The airbag 23 is connected to the bottom of the mounting box 22. The L-shaped plate 24 is slidably connected inside the mounting box 22. The outer wall of the airbag 23 is in contact with the inner wall of the L-shaped plate 24. The connecting plate 25 is connected to the top of the airbag 23. Eight springs 26 are connected between the bottom of the connecting plate 25 and the bottom of the mounting box 22. The inflation assembly is used to inflate the airbag 23 with air, causing the airbag 23 to expand. The L-shaped plate 24 blocks the airbag 23.

[0039] like Figure 11 and Figure 12 As shown, the inflation assembly includes an air pump 27, an air inlet pipe 28, a one-way valve 29, an exhaust pipe 30, and a valve 31. The air pump 27 is bolted to the bottom right side of the bed board 1. The air inlet pipe 28 is connected to the air outlet end of the air pump 27. The upper end of the air inlet pipe 28 is connected to the bottom of the mounting box 22, and the air inlet pipe 28 and the mounting box 22 are connected. The one-way valve 29 is connected to the air inlet pipe 28. The exhaust pipe 30 is connected to the bottom left side of the air inlet pipe 28. The valve 31 is connected to the exhaust pipe 30.

[0040] The nurse can activate the air pump 27, and air enters the airbag 23 through the air inlet pipe 28, causing the airbag 23 to inflate. The airbag 23 pushes the L-shaped plate 24 upward. Under the action of the one-way valve 29, the air in the air inlet pipe 28 will not flow back. After the airbag 23 inflates, the connecting plate 25 will also move upward, and the second spring 26 will stretch. The pregnant woman can lie on her side and rest against the airbag 23. The airbag 23 supports the pregnant woman, and the L-shaped plate 24 blocks the airbag 23 to prevent it from shifting. Lying on her side can reduce the pressure on the inferior vena cava and the abdominal aorta, making the pregnant woman more comfortable. Open the valve 31, and the air in the air inlet pipe 28 will be discharged through the exhaust pipe 30. The airbag 23 will return to its original shape. Under the action of the second spring 26, the connecting plate 25 will move downward to reset. The connecting plate 25 will pull the airbag 23 downward, so that the airbag 23 moves back into the installation box 22.

[0041] like Figure 13 and Figure 14 As shown, it also includes a fixing mechanism, which includes a U-shaped locking block 32, a spring 33, and a U-shaped rod 34. The bottom of the slider 4 and the bottom of the slide plate 5 are slidably connected to the U-shaped locking block 32. The bottom of the slider 4 and the bottom of the slide plate 5 are each connected to two springs 33. The lower end of the spring 33 is connected to the U-shaped locking block 32. The bottom of the two U-shaped locking blocks 32 are connected to the U-shaped rod 34.

[0042] The U-shaped locking block 32 can hold the connecting block 6 in place to prevent the round box 7 from falling. When the round box 7 needs to be removed, the caregiver pulls down the U-shaped rod 34. The U-shaped rod 34 moves the U-shaped locking block 32 downward, and the spring 33 stretches. After the U-shaped locking block 32 releases the connecting block 6, the round box 7 can be removed.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
