Description

Technical Field

[0001] The utility model relates to the technical field of nursing beds, and particularly relates to an obstetric nursing mother and baby bed. Background Art

[0002] In the obstetrics department of a hospital, a mother and baby bed is a nursing facility designed specifically for newborns and their mothers, aiming to achieve co-room nursing for the mother and baby. Although there are currently some integrated mother and baby beds that combine a maternity bed and a baby bed, these mother and baby beds still have the following drawbacks:

[0003] For example, a mother and baby bed disclosed in a Chinese invention patent application with the application publication number CN112690963A. Although this mother and baby bed can store the baby bed when it is not in use, saving space, the baby bed is entirely located below the bed surface of the mother bed in both the stored state and the unfolded state. Since the baby bed cannot be raised after being unfolded, things on the mother bed are likely to fall onto the baby bed in the unfolded state, leading to safety hazards, such as a mobile phone falling from the mother bed and injuring the baby. Another mother and baby bed disclosed in a utility model patent document with the authorization publication number CN219042868U. Although the height difference between the bed surface of the mother bed and the bed surface of the baby bed is relatively small, when the baby bed is not needed, it cannot be stored under the mother bed, making it inconvenient to store the baby bed.

[0004] In view of this, the applicant has conducted in-depth research on the above problems, and thus this case has arisen. Summary of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0052] Embodiment 1

[0053] As Figures 1 to 6 shown, this embodiment provides an obstetric care mother - baby bed, which has a storage state and an unfolded state. For the convenience of description, the storage state is taken as an example for explanation.

[0054] An obstetric care mother - baby bed includes a mother bed 100 and a baby bed 200.

[0055] Taking one side in the length direction of the mother bed 100 as the front - side direction, the corresponding opposite - side direction is the rear - side direction; taking one side in the width direction of the mother bed 100 as the left - side direction, the corresponding opposite - side direction is the right - side direction.

[0056] The main bed 100 includes a bed frame 110 and feet 120, and the feet 120 are fixed to the bed frame 110; the sub - bed 200 is located on the lower side of the bed frame 110; the sub - bed 200 includes a first frame 210, a second frame 220, and a third frame 230 that are horizontally arranged in sequence from top to bottom. A vertically arranged sliding rod 221 is slidably connected to the second frame 220. In this embodiment, there are two sliding rods 221, which are the first sliding rod and the second sliding rod respectively. The first sliding rod is slidably connected to the front end of the second frame 220, and the second sliding rod is slidably connected to the rear end of the second frame 220. The structures of the two sliding rods 221 are the same; the upper ends of the two sliding rods 221 are both fixed to the first frame 210, and the lower ends of the two sliding rods 221 are both fixed to the third frame 230. Specifically, the upper end of the first sliding rod is fixed to the middle of the front end of the first frame 210, the lower end of the first sliding rod is fixed to the middle of the front end of the third frame 230, the upper end of the second sliding rod is fixed to the middle of the rear end of the first frame 210, and the lower end of the second sliding rod is fixed to the middle of the rear end of the third frame 230. For the convenience of description, one of the sliding rods 221 is taken as an example for illustration.

[0057] The second frame 220 is horizontally slidably connected to the lower side of the bed frame 110. In this embodiment, two mutually parallel guide rails 111 are fixed to the lower side of the bed frame 110. The two guide rails 111 are the first guide rail and the second guide rail respectively, and both the first guide rail and the second guide rail are arranged in the left - right direction.

[0058] The sliding directions of the tracks of the first guide rail and the second guide rail are both in the left - right direction.

[0059] In this embodiment, taking the case where the sub - bed 200 is located on the left side of the main bed 100 after the obstetric care mother - infant bed is unfolded as an example, the left direction is the pulling - out direction of the first guide rail and the second guide rail, and the right direction is the retracting direction of the first guide rail and the second guide rail.

[0060] It should be noted that after the obstetric care mother - infant bed of the present utility model is unfolded, the sub - bed 200 can also be located on the right side of the main bed 100. At this time, the right direction is the pulling - out direction of the first guide rail and the second guide rail, and the left direction is the retracting direction of the first guide rail and the second guide rail.

[0061] The first guide rail is located in front of the sub - bed 200, and the second guide rail is located behind the sub - bed 200; the second frame 220 is provided with two supporting members 222, which are the first supporting member and the second supporting member respectively; one end of the first supporting member is fixed to the front side of the second frame 220, and the other end is slidably connected to the first guide rail; one end of the second supporting member is fixed to the rear side of the second frame 220, and the other end is slidably connected to the second guide rail.

[0062] The sliding rod 221 is provided with a horizontally arranged locking hole, and the distance between the locking hole and the third frame 230 matches the thickness of the second frame 220.

[0063] A downward sliding locking rod 223 is inserted through the locking hole. The length of the downward sliding locking rod 223 is greater than the diameter of the sliding rod 221. After the downward sliding locking rod 223 is inserted into the locking hole, at least one end of the downward sliding locking rod 223 is located outside the locking hole. The part of the locking rod located outside the locking hole abuts against the upper end surface of the second frame 220. The downward sliding locking rod 223 is used to limit the downward sliding of the sliding rod 221.

[0064] When adjusting the obstetric care mother and baby bed from the storage state to the unfolded state, the main operation steps are as follows: Pull the second frame 220 of the sub-bed 200 along the left side direction of the mother bed 100 until the first frame 210 and the horizontal projection plane of the mother bed 100 are completely separated; then remove the downward sliding locking rod 223 from the locking hole; then lift the first frame 210 upward until the locking hole is completely above the second frame 220; finally, insert the downward sliding locking rod 223 into the locking hole. Both ends of the downward sliding locking rod 223 are outside the locking hole, and the lower sides of both ends of the downward sliding locking rod 223 respectively abut against the upper end surface of the second frame 220. The downward sliding locking rod 223 is used to limit the downward sliding of the sliding rod 221.

[0065] Furthermore, an operation handle 224 is fixed to one end of the downward sliding locking rod 223. The operation handle 224 is perpendicularly arranged with the downward sliding locking rod 223. The operation handle 224 is provided for operating the downward sliding locking rod 223 to be inserted into or removed from the locking hole; a handle seat 225 is fixed to the second frame 220; in the unfolded state, the operation handle 224 is detachably connected to the handle seat 225. Specifically, the handle seat 225 includes a chassis fixed to the second frame 220 and an elastic buckle arranged on the chassis. The operation handle 224 is pressed and engaged on the elastic buckle; in the storage state, the operation handle 224 is separated from the handle seat 225. It should be noted that the elastic buckle is a conventional existing structure and will not be elaborated here.

[0066] By providing the operation handle 224 and the handle seat 225, the operation handle 224 and the handle seat 225 are detachably connected together in the unfolded state, which is beneficial to preventing the downward sliding locking rod 223 from being separated from the locking hole due to accidental collision during use, resulting in the failure of downward sliding locking.

[0067] The sub-bed 200 further includes a spring 240 and a telescopic rod 241. The spring 240 is sleeved on the telescopic rod 241. One end of the spring 240 is fixed to the second frame 220, and the other end is fixed to the third frame 230. One end of the telescopic rod 241 is fixed to the second frame 220, and the other end is fixed to the third frame 230. Specifically, the third frame 230 is vertically slidably connected with a spring box 232 with an upward opening. The height of the spring box 232 is greater than the distance from the upper end to the lower end of the third frame 230. The distance between the two ends of the telescopic rod 241 after being fully contracted is less than or equal to the internal net height of the spring box 232. The length of the spring 240 after being compressed to the limit is less than or equal to the internal net height of the spring box 232. The end of the telescopic rod 241 far from the second frame 220 is fixed to the bottom of the spring box 232, and the end of the spring 240 far from the second frame 220 is fixed to the bottom of the spring box 232.

[0068] It should be noted that the number of telescopic rods 241 sleeved in the spring 240 can be one or more than one. In this embodiment, the case where there are more than one telescopic rods 241 sleeved in the spring 240 is taken as an example for description. The telescopic rod 241 is a conventional existing structure, such as a telescopic rod disclosed in a Chinese patent document with the application number CN202221179232.4.

[0069] The telescopic rod 241 plays a supporting and guiding role during the compression process of the spring 240, ensuring the stability of the spring 240 during the compression process.

[0070] The outer edge of the opening of the spring box 232 is fixed with a wing plate, and the bottom of the spring box 232 is provided with a bottom end plate of the box. The wing plate is located on the upper side of the third frame 230, and the bottom end plate of the box is located on the lower side of the third frame 230. An wing plate groove matching the wing plate is opened at the upper end of the third frame 230, and the depth of the wing plate groove is greater than the thickness of the wing plate.

[0071] In the unfolded state, the lower end of the wing plate of the spring box 232 abuts against the bottom of the wing plate groove, and the spring 240 and the telescopic rod 241 are completely inside the spring box 232, and the spring 240 is in a compressed state.

[0072] In the storage state, the upper end of the bottom end plate of the spring box 232 abuts against the lower end of the third frame 230, and the spring 240 is in a stretched state.

[0073] By setting the spring 240, after the downward-sliding locking rod 223 separates from the locking hole, the downward sliding of the first frame 210 can be buffered, preventing the first frame 210 from directly hitting the second frame 220 due to inertia. By setting the spring box 232, the spring 240 is compressed into the spring box 232 in the unfolded state, which helps prevent the spring 240 from being compressed and damaged and spreading around, avoiding accidental injury to users. Further, the sub-bed 200 further includes an upward-sliding locking group 250. The upward-sliding locking group 250 includes a self-locking spring 251 and a horizontally arranged self-locking rod 252. The self-locking rod 252 includes a pull head 252a, a square rod body 252b, an end plate 252c, and a clamping head 252d that are integrally connected in sequence on the same straight line. The axis of the square rod body 252b of the self-locking rod 252 is parallel to the normal line of the end plate 252c of the self-locking rod 252. The square rod body 252b of the self-locking rod 252 and the sliding rod 221 are located in the same plane and the square rod body 252b of the self-locking rod 252 is perpendicularly arranged with respect to the sliding rod 221. The square rod body 252b of the self-locking rod 252 is located between the upper end face and the lower end face of the second frame 220. The square rod body 252b of the self-locking rod 252 is horizontally slidably connected to the second frame 220 and the pull head 252a of the self-locking rod 252 is located outside the area enclosed by the second frame 220. The self-locking spring 251 is sleeved on the square rod body 252b of the self-locking rod 252, and one end of the self-locking spring 251 abuts against the end plate 252c of the self-locking rod 252, and the other end abuts against the second frame 220. The clamping head 252d of the self-locking rod 252 abuts against the sliding rod 221. The lower end face of the clamping head 252d of the self-locking rod 252 is a plane parallel to the horizontal plane, and the upper end face of the clamping head 252d is an inclined plane that gradually approaches the lower end face of the clamping head 252d of the self-locking rod 252 from the end close to the end plate 252c of the self-locking rod 252 to the end far from the end plate 252c of the self-locking rod 252. The sliding rod 221 is provided with a card slot matching the clamping head 252d of the self-locking rod 252. The distance from the lower end face of the clamping head 252d of the self-locking rod 252 to the lower end face of the bed frame 110 is greater than or equal to the distance from the lower side wall of the card slot to the upper end of the first frame 210. In the storage state, the clamping head 252d of the self-locking rod 252 abuts against the card slot. The upward-sliding locking group 250 is provided to limit the upward sliding of the sliding rod 221, avoiding the upward sliding of the sliding rod 221 under the pulling force of the spring 240 in the storage state.

[0074] Further, the side wall of the first frame 210 is further provided with a lifting opening 213. In this embodiment, the left side wall and the right side wall of the first frame 210 are both provided with lifting openings. By providing the lifting opening 213 on the side wall of the first frame 210, it is convenient to apply an upward pulling force to the first frame 210.

[0075] A vertically arranged enclosing upright rod 214 is also provided between the first frame 210 and the third frame 230. The upper end of the enclosing upright rod 214 is rotatably connected to the first frame 210, and the lower end of the enclosing upright rod 214 is rotatably connected to the third frame 230. Specifically, enclosing upright rods 214 are provided on the front side, rear side, left side, and right side of the sub-bed 200. Further, a push-pull handle 226 is also provided on the second frame 220. Specifically, the push-pull handle 226 is provided on the left side wall of the second frame 220. The provision of the push-pull handle 226 facilitates pulling out and retracting the second frame 220 of the sub-bed 200 from under the mother bed 100.

[0076] The sub-bed 200 further includes a mattress 260 and a bottom plate 270. The bottom plate 270 is installed on the third frame 230, and the mattress 260 is placed above the bottom plate 270; blocking cushions 261 are provided around the mattress 260. The provision of the blocking cushions 261 prevents the baby from hitting the enclosing upright rod 214 or the sliding rod 221 due to restlessness or turning over. Further, a second mattress 262 and a support pad 263 are also provided on the mattress 260. The upper end surface of the second mattress 262 is an inclined surface with a gradually increasing height from the end close to the rear side of the sub-bed 200 to the end far from the rear side of the sub-bed 200; the support pad 263 is provided on the upper end surface of the second mattress 262 close to the rear side of the sub-bed 200. The upper end surface of the second mattress 262 is arranged obliquely, and the baby lies along the inclined direction, which is beneficial to preventing the baby from spitting up; the support pad 263 is provided to support the baby's buttocks, prevent the baby from sliding down from the second mattress 262, and improve the comfort of the baby's lying position.

[0077] When adjusting the obstetric care mother and baby bed from the unfolded state to the stored state, the main operation steps are as follows: Remove the lower sliding locking rod 223 from the locking hole, then slide the first frame 210 downward until the chuck 252d of the self-locking rod 252 abuts against the card slot, and finally the sub-bed 200 can be easily pushed under the mother bed 100.

[0078] With the above technical solutions, the storage state and the unfolded state of the obstetric care mother and baby bed can be adjusted easily and simply. During the unfolding process, the sub-bed 200 can be lifted, so that the height difference between the bed frame of the mother bed 100 and the third frame 230 of the sub-bed 200 is relatively small, thereby reducing or even eliminating the safety hazards caused by the items on the mother bed 100 falling; when the sub-bed 200 is not needed, the sub-bed 200 can also be easily stored under the mother bed 100, and the sub-bed 200 is convenient to store.
