Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a multifunctional bed for children. Background Art

[0002] At present, for some beds for pediatric patients in hospitals, fences are usually set on both sides of the beds to prevent patients from falling out of bed. In addition, in order to facilitate patients getting in and out of bed, at least one side of the fence is usually designed to be a liftable fence, and the fence is lowered when the patient needs to get out of bed.

[0003] Although the presence of the fence reduces the risk of patients falling out of bed to a great extent, in actual application, sometimes some patients' families forget to raise the guardrail, which makes it easy for the children to climb to the side where the guardrail is not raised, resulting in the risk of falling out of bed. Therefore, there is still room for improvement. Summary of the invention

[0008] As an optional embodiment of the present application, a linkage mechanism is further provided between the floating plate and the bed board; the linkage mechanism includes a guide rod and a push block, the guide rod is vertically movably arranged on the bed board, the upper end of the guide rod is fixed to the floating plate, and the lower end extends out of the bed board; the push block is fixed to the movable guardrail and rises and falls synchronously with the movable guardrail, and the push block at least partially extends to the bottom of the guide rod for pushing the guide rod upward; when the movable guardrail is in the raised position, the guide rod drives the floating plate into the non-working position under the push of the push block; when the movable guardrail is in the lowered position, the guide rod is detached from the push block.

[0009] As an optional implementation of the present application, the linkage mechanism further includes a spring, and the spring is used to increase the elastic force to push the floating plate to have a tendency to move toward the working position.

[0010] As an optional embodiment of the present application, a receiving groove capable of accommodating a floating board is provided on the top surface of the bed board; a surrounding plate is provided around the bottom of the floating board, the surrounding plate extends vertically and can slide along the peripheral wall of the receiving groove; the vertical length of the floating board is constructed as follows: when the floating board is in a non-working position, the lower end of the surrounding plate does not exceed the top notch of the receiving groove; when the floating board is in a working position, the lower end of the floating board forms a gap with the bottom of the receiving groove.

[0011] As an optional embodiment of the present application, the child's bed also includes a humidity detection mechanism, which includes a humidity sensor for detecting the humidity of the child's diaper, and the humidity sensor is connected to the control system. When the humidity value detected by the humidity sensor is greater than a set value, the control system sends a second warning signal.

[0012] As an optional embodiment of the present application, the humidity detection mechanism also includes a fixing component; the fixing component includes a moisture conductive body, a first ring piece and a second ring piece; one side of the first ring piece is axially extended to form an extension portion, and the center of the extension portion has a through hole connecting the ring hole of the first ring piece; the ring hole of the second ring piece can be inserted into the extension portion; a cover is provided on the humidity sensor; the electrodes of the humidity sensor are arranged in the cover; the cover can be detachably connected to the extension portion; the moisture conductive body can at least partially penetrate into the first through hole.

[0015] As an optional implementation of the present application, the humidity sensor is wirelessly connected to the control system.

[0016] Compared with the prior art, this application has the following beneficial effects: In the present application, a warning zone is set on the bed board, so that when the movable guardrail is lowered, when the child climbs into the warning zone, the warning zone is triggered, thereby sending an alarm signal through the control system to alert the child's caregiver and / or medical staff.

[0017] Moreover, in the present application, the warning zone is linked to the movable guardrail. When the movable guardrail is in the raised position, the warning zone is in a non-working state, that is, at this time, no matter whether there is weight in the warning zone, the warning zone will not trigger a warning signal. Such a design takes into account that when the movable guardrail is in the raised position, there is already a movable guardrail to block the child, and it is difficult for the child to fall out of bed easily. On this basis, if the warning zone is still in a working state, the following situation will occur. When the child turns over to the warning zone during sleep, the control system will send out a warning signal. Obviously, there is no danger with the presence of the guardrail at this time, and therefore the warning signal is equivalent to a false alarm signal and has no substantive significance.

[0018] When the movable guardrail is in the lowered position, there is no guardrail to block the guardrail, so the warning zone is in working state. Once the child climbs into the warning zone, the warning signal will be triggered. This design is equivalent to that when the movable guardrail is lowered, the warning zone automatically enters the working state, and there is no need to manually open the warning zone, thus avoiding the problem of forgetting to open the warning zone to enter the working state when the movable guardrail is lowered.

[0023] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0024] Example 1 Reference Figure 1-5 As shown, this embodiment provides a multifunctional bed for children, including a bed frame 1, guardrails and a control system, etc. The following is a specific description of each component: like Figure 1 As shown, the bed frame 1 is mainly used to support the bed board 3, which mainly includes four upright posts 11 distributed in a rectangular shape, and a connecting frame connected between the upright posts 11; and the bed board 3 is fixed between the upright posts 11 and is in a horizontal state.

[0025] Two guardrails are provided, and the two guardrails are respectively provided on both sides of the bed board 3, and at least one of the guardrails on both sides is a movable guardrail 2, and the movable guardrail 2 can move between a raised position and a lowered position relative to the bed board 3; the two guardrails mainly include the following two situations: First, the guardrail on one side is a fixed guardrail that cannot be raised or lowered, and the enclosure is on one side of the guardrail, and the guardrail on the other side is a movable guardrail 2 that can be raised or lowered vertically. Second, the guardrails on both sides are movable guardrails 2 that can be raised or lowered vertically. This embodiment shows the situation where both sides are movable guardrails 2.

[0026] The movable guardrail 2 can be raised and lowered manually, referring to the manual lifting guardrail used on existing hospital beds. It can also be raised and lowered electrically, for example: like Figure 2 As shown, a vertically extending slide groove 111 is provided on the side wall on the opposite side of the two columns 11 on the side of the bed board 3; sliders 113 are provided on both sides of the movable guardrail 2, and the sliders 113 are slidably set in the slide groove 111; in addition, a vertically extending screw 112 is rotatably connected in the slide groove 111; the slider 113 is threadedly connected to the screw 112, and the screw 112 is driven to rotate by a motor, so that the motor drives the screw 112 to rotate, which can drive the slider 113 to slide vertically in the slide groove 111, and then the slider 113 drives the movable guardrail 2 to rise and fall vertically.

[0027] In this embodiment, Figure 1 As shown, the movable guardrail 2 is in the raised position, and the movable guardrail 2 at least partially extends out of the upper side of the bed board 3 to form a fence for the side of the bed board 3; Figure 4As shown, the movable guardrail 2 is in the lowered position and the guardrail does not extend beyond the top surface of the bed board 3 .

[0028] In this embodiment, if Figure 1 As shown, the bed board 3 includes a lying area 31 and a warning area 32. The lying area 31 is the main position for the sick child to lie down and sleep; and the warning area 32 is a warning area. Specifically: The warning area 32 is located between the movable guardrail 2 and the lying area 31 and extends along the length direction of the bed board 3; for example, in this embodiment, the guardrails on both sides are movable guardrails 2, which correspond to two warning areas 32. Along the width direction of the bed board 3, the lying area 31 is located between the two warning areas 32, and each warning area 32 corresponds to the movable guardrail 2 on the same side of itself and is interconnected with it.

[0029] The warning area 32 is connected to a control system, which mainly includes a controller. The warning area 32 is configured such that, in a working state, when the pressure in the warning area 32 is greater than a set value, the warning area 32 is triggered, and the control system sends a first warning signal. The first warning signal here can be a sound signal, for example, Figure 1 As shown, a buzzer 35 is provided on the bed frame 1. When the warning zone 32 is triggered, the buzzer 35 sounds to remind the caregiver and medical staff of the child. Of course, the first warning signal can also be a light signal; it can also be a message. For example, when the warning zone 32 is triggered, the control system sends a reminder message to the central control display of the nurse station.

[0030] The working state and non-working state here can be understood as follows: the non-working state refers to the state where the warning zone 32 is released from the warning state, that is, even if the warning zone 32 is subjected to pressure, the first warning signal will not be triggered; and the working state refers to the state where the warning zone 32 enters the warning state, that is, when the pressure on the warning zone 32 is greater than the set value, the warning zone 32 will be triggered. In short, the non-working state is equivalent to the shutdown state, and the working state is equivalent to the startup state.

[0031] In this way, when the movable guardrail 2 is lowered, when the child crawls into the warning area 32, the warning area 32 is triggered, so that a warning signal is sent through the control system to remind the child's caregiver and / or medical staff.

[0032] In addition, the warning area 32 is also linked with the movable guardrail 2, and the linkage relationship is: like Figure 5As shown, when the movable guardrail 2 is in the raised position, the warning zone 32 is in a non-working state. At this time, because the movable guardrail 2 is raised, the warning zone 32 may not be opened. At this time, regardless of whether there is weight in the warning zone 32, the warning zone 32 will not trigger the warning signal. This design takes into account that when the movable guardrail 2 is in the raised position, the movable guardrail 2 is already there to block the child, and it is difficult for the child to fall out of bed. On this basis, if the warning zone 32 is still in a working state, the following situation will occur. When the child turns over to the warning zone 32 during sleep, the control system will still send out a first warning signal. Obviously, there is no danger with the presence of the guardrail at this time, and thus the first warning signal is equivalent to a false alarm signal and has no substantive significance.

[0033] like Figure 4 As shown, when the movable guardrail 2 is in the lowered position, the warning zone 32 is in working condition. When the movable guardrail 2 is in the lowered position, there is no obstruction of the movable guardrail 2, so the warning zone 32 is in working condition. Once the child climbs to the warning zone 32, a warning signal will be triggered.

[0034] Moreover, such a design is equivalent to that when the movable guardrail 2 is lowered, the warning zone 32 automatically enters the working state, and there is no need to manually open the warning zone 32, thereby avoiding the problem of forgetting to open the warning zone 32 to enter the working state when the movable guardrail 2 is lowered.

[0035] Furthermore, it is understandable that in addition to the automatic opening and closing of the warning zone 32 as described above, an additional manual opening and closing operation may be provided. For example, a control switch is provided to control whether the warning zone 32 is activated or not. When the switch is turned on, the warning zone 32 is activated and enters a working state. When the switch is turned off, the warning zone 32 is closed and enters a non-working state.

[0036] In this embodiment, Figure 3 As shown, the specific structure of the warning area 32 is: the warning area 32 includes a floating plate 4 arranged on the bed board 3 and can move vertically between a working position and a non-working position relative to the bed board 3; the floating plate 4 extends along the length direction of the bed board 3.

[0037] One or more pressure sensors 34 are provided between the floating plate 4 and the bed board 3; the multiple pressure sensors 34 are evenly distributed in sequence along the length direction of the floating plate 4, wherein the lower end of the pressure sensor 34 is fixed on the bed board 3, and the upper end serves as a pressure detection end for contacting the floating plate 4 to realize pressure detection.

[0038] When the floating plate 4 is in the non-working position, that is, Figure 5In the state shown, a gap is formed vertically between the float plate 4 and the detection end of the pressure sensor 34, that is, the float plate 4 is suspended on the upper side of the pressure sensor 34 and has no contact with the pressure sensor 34. In this way, no matter whether pressure is applied to the float plate 4, the float plate 4 will not contact the pressure sensor 34, so that the pressure sensor 34 will not be pressurized and no pressure detection signal will be generated. In this way, the warning area 32 remains in a non-working state.

[0039] In addition, in this embodiment, the movable guardrail 2 and the floating plate 4 are linked to each other, specifically: When the floating plate 4 is in the working position, Figure 4 In the state shown, the float plate 4 is superimposed on the detection end of the pressure sensor 34, so that the warning area 32 enters the working state; that is, the float plate 4 is located on the top surface of the pressure sensor 34 and is supported by the pressure sensor 34. At this time, if the child climbs onto the float plate 4, the float plate 4 will transmit pressure to the pressure sensor 34, and the pressure sensor 34 will detect the pressure value. When the pressure value is greater than the set value, the control system will send a first warning signal.

[0040] When the movable guardrail 2 is in the raised position, Figure 5 In the state shown, the floating plate 4 is in a non-working position, so that the warning zone 32 enters a non-working state; when the movable guardrail 2 is in the lowered position, the floating plate 4 is in a working position, so that the warning zone 32 enters a working state. At this time, when the pressure signal detected by the pressure sensor 34 is greater than the set value, the control system sends a first warning signal.

[0041] In order to realize the linkage between the movable guardrail 2 and the floating plate 4, in this embodiment, a linkage mechanism 5 is further provided between the floating plate 4 and the bed plate 3. It can be understood that the linkage mechanism 5 can be one or more. For example, in this embodiment, two linkage mechanisms 5 are provided, which are respectively provided on both sides of the bottom of the floating plate 4.

[0042] Combination Figure 4 and Figure 5 As shown, the linkage mechanism 5 includes a guide rod 51 and a push block 52. The guide rod 51 is vertically movably arranged on the bed board 3. Preferably, the guide rod 51 is arranged on the bed board 3 through a linear bearing to reduce the friction force when the guide rod 51 slides vertically relative to the bed board 3.

[0043] Among them, the upper end of the guide rod 51 is fixed to the floating plate 4, and the lower end extends out of the bed board 3; the push block 52 is fixed on the movable guardrail 2 and rises and falls synchronously with the movable guardrail 2, and the push block 52 at least partially extends to the bottom of the guide rod 51 to push the guide rod 51 upward. For example, in some embodiments, the push block 52 is roughly L-shaped.

[0044] In this way, when the movable guardrail 2 moves from the lowered position to the raised position, that is, moves from bottom to top, the push block 52 moves from bottom to top synchronously. After the push block 52 contacts the lower end of the guide rod 51, as the push block 52 continues to move upward, the push block 52 will push the guide rod 51 to move upward, and then push the floating plate 4 to move upward, so that the floating plate 4 gradually moves upward away from the pressure sensor 34; until the movable guardrail 2 is in the raised position, the floating plate 4 enters the non-working position, at which time a gap is formed between the floating plate 4 and the pressure sensor 34, which can be referred to Figure 5 Status shown.

[0045] When the movable guardrail 2 moves from the raised position to the lowered position, that is, moves from top to bottom, the push block 52 will also move downward synchronously. During this process, the floating plate 4 will move downward under its own weight and finally sit on the pressure sensor 34. At this time, the floating plate 4 enters the working position; thereafter, the floating plate 4 will not continue to move downward, and the guide rod 51 will gradually separate from the push block 52 until the movable floating plate 4 enters the lowered position. Figure 4 Status shown.

[0046] In the above embodiments, the floating plate 4 enters the working position by self-resetting, so the gravity of the floating plate 4 needs to be sufficient, which also leads to the need to increase the weight of the floating plate 4. Based on this, in order not to increase the weight of the floating plate 4, the floating plate 4 can also be reset to the working position more smoothly. In some embodiments: like Figure 4 As shown, the linkage mechanism 5 further includes a spring 53, which is used to increase the elastic force to push the floating plate 4 to have a tendency to move toward the working position. For example, in this embodiment, the spring 53 is a tension spring, which is sleeved on the guide rod 51, and the upper end of the spring 53 is fixed to the bottom wall of the floating plate 4, and the lower end is fixed to the bed plate 3; thus, under the tension of the spring 53, the floating plate 4 has a tendency to move downward. At this time, the floating plate 4 is equivalent to being reset to the working position by the combined action of its own gravity and the tension of the spring 53.

[0047] Since there is a gap between the floating plate 4 and the bed board 3 when the floating plate 4 is in the non-working position, once debris falls into the gap and the debris is higher than the top surface of the pressure sensor 34, the floating plate 4 cannot descend to sit on the pressure sensor 34 due to the obstruction of the debris, and thus cannot enter the working state normally.

[0048] Based on this, in some embodiments, such as Figure 3 As shown, the top surface of the bed board 3 is provided with a receiving groove 33 capable of receiving the floating board 4, and the receiving groove 33 is adapted to the shape of the floating board 4. For example, in this embodiment, the cross section of the floating board 4 is rectangular, and the cross section of the corresponding receiving groove 33 is also rectangular.

[0049] In addition, a surrounding plate 41 is provided around the bottom of the floating plate 4 , and the surrounding plate 41 extends vertically, which is equivalent to that each side edge of the floating plate 4 is bent downward to form the surrounding plate 41 , thereby forming a rectangular frame structure around the lower side of the floating plate 4 .

[0050] In addition, the surrounding plate 41 can slide along the peripheral wall of the receiving groove 33 , and the surrounding plates 41 at the four sides respectively slide up and down along the peripheral groove walls of the receiving groove 33 . The pressure sensor 34 is fixed on the bottom wall of the receiving groove 33 .

[0051] The vertical length of the floating plate 4 is constructed as follows: Figure 5 As shown, when the float plate 4 is in the non-working position, the lower end of the enclosure 41 does not exceed the top notch of the receiving groove 33, or in other words, the lower end of the enclosure 41 does not exceed the top surface of the bed board 3. In this way, a relatively closed space is formed between the float plate 4, the enclosure 41, and the bottom wall of the receiving groove 33, and the pressure sensor 34 is located in the space; making it difficult for debris to enter the space, thereby not affecting the descent of the float plate 4 to the working position.

[0052] In addition, the vertical length of the floating plate 4 is also configured as follows: Figure 4 As shown, when the floating plate 4 is in the working position, the lower end of the floating plate 4 forms a gap with the bottom of the receiving groove 33. If the two are in contact, the bottom of the receiving groove 33 will support the floating plate 4, thereby causing the pressure sensor 34 to be unable to accurately detect the pressure applied by the floating plate 4.

[0053] Example 2 For some younger children, since they cannot take care of themselves, they usually need to wear diapers M (also commonly known as diapers). For some children wearing diapers M, if the diapers M are not changed in time after they urinate or defecate, it is easy to cause symptoms such as dermatitis.

[0054] Therefore, this embodiment makes further improvements on the basis of embodiment 1, specifically: Figure 6 and Figure 7 As shown, the child bed provided in this embodiment also includes a humidity detection mechanism including a humidity sensor 7 for detecting the humidity of the child's diaper M. The humidity sensor 7 is connected to the control system. When the humidity value detected by the humidity sensor 7 is greater than the set value, the control system sends a second warning signal. The second warning signal can be a sound / light / message signal. For details, please refer to the description of the first warning signal in Example 1. It is worth noting that the first warning signal should be distinguished from the second warning signal. For example, if both use sound signals, two different sound signals need to be set to distinguish different warning messages.

[0055] The humidity sensor 7 and the control system may be connected by wired communication or wireless communication. For example, the two may be connected by Bluetooth or WIFI.

[0056] In some embodiments, when in use, the electrode 71 of the humidity sensor 7 is directly placed on the inner side of the diaper M for detection. It is understood that the inner side of the diaper claimed in this embodiment refers to the side of the diaper facing the human skin.

[0057] In some other embodiments, the humidity detection mechanism further includes a fixing component 6; Figure 6 As shown, the fixing assembly 6 includes a moisture-conducting body 63, a first ring piece 61 and a second ring piece 62; one side of the first ring piece 61 is axially extended to form an extension portion 611; wherein the first ring piece 61 and the second ring piece 62 are preferably made of rubber material, and the extension portion 611 can be a rubber material or a plastic part, a hard metal part, etc.; the extension portion 611 is cylindrical.

[0058] The center of the extension part 611 has a through hole 612 connected to the ring hole of the first ring piece 61; the ring hole of the second ring piece 62 can be inserted into the extension part 611; the humidity sensor 7 is provided with a cover 72; the electrode 71 of the humidity sensor 7 (the electrode 71 here refers to the detection end of the humidity sensor 7 for detecting humidity, also called a probe) is arranged in the cover 72.

[0059] The cover 72 can be detachably connected to the extension portion 611, for example, the two are connected by threads. Specifically, an external thread is provided on the outer peripheral wall of the extension portion 611, and an internal thread matched with the external thread is provided on the inner peripheral wall of the cover 72. When assembling, the cover 72 can be screwed onto the extension portion 611.

[0060] The moisture conductive body 63 is a material capable of absorbing moisture. Specifically, the moisture conductive body 63 can at least partially penetrate into the first through hole 612. For example: The moisture conductive body 63 includes a moisture conductive fabric 631 and a moisture conductive core 632. The moisture conductive fabric 631 here can be a moisture-absorbing cotton cloth or a moisture-absorbing sponge, and the moisture conductive core can be a moisture-absorbing cotton swab or a moisture-absorbing sponge swab.

[0061] One side of the moisture conductive core 632 is an adhesive surface that can be adhered to the diaper M, for example, the adhesive surface is coated with glue; one end of the moisture conductive core is fixed on the adhesive surface of the moisture conductive core; wherein, the moisture conductive fabric and the moisture conductive core can be an integral structure, or can be two components connected to each other.

[0062] When using, Figure 7As shown in the figure, first, a hole is punched on the diaper M for the extension part 611 to pass through, and the hole passes through the inner and outer sides of the diaper M; then, the extension part 611 passes through the hole from the inner side of the diaper M to the outer side, and at this time, the first ring piece 61 is on the inner side of the diaper M; then, the moisture conductive core body is inserted from the inner side of the diaper M into the through hole 612 in the extension part 611, and the moisture conductive fabric is adhered to the inner side of the diaper M through the adhesive surface; then, On the outside of the diaper M, put the second ring piece 62 onto the extension part 611, and then put the cover 72 onto the extension part 611 and gradually tighten the cover 72; as the cover 72 is tightened, the cover 72 will push the second ring piece 62 axially to gradually approach the first ring piece 61, and finally clamp the diaper M between the first ring piece 61 and the second ring piece 62. At this time, the electrode 71 of the humidity sensor 7 is inserted into the through hole 612 and contacts with the moisture conductive core 632 to complete the fixation.

[0063] In this way, when the child urinates, part of the urine will be transferred to the moisture conductive core 632 through the moisture conductive fabric 631, so that the electrode 71 of the humidity sensor 7 detects the humidity of the moisture conductive core 632. When the humidity is greater than the set value, the control system sends a second warning signal.

[0064] In this embodiment, the design of the fixing component 6 can make the humidity sensor 7 firmly mounted on the diaper and not easy to fall off. Moreover, with such a design, the humidity sensor 7 is arranged on the outside of the diaper M as a whole. Compared with the method of placing the humidity sensor 7 on the inside of the diaper M for detection, it is undoubtedly more difficult for the humidity sensor 7 to be contaminated by urine and feces.

[0065] In the present embodiment, the moisture-conducting fabric has two main functions: one is to conduct moisture; the other is to shield the first ring piece 61 to prevent the child's skin from directly contacting the first ring piece 61 .

[0066] Moreover, in this embodiment, the design of the fixing component 6, through the clamping of the first ring piece 61 and the second ring piece 62, can form a certain shielding and plugging effect on the hole punched on the diaper M for the extension part 611 to pass through, thereby reducing the leakage of urine from the hole.
