Description

Technical Field

[0001] The invention relates to the technical field of bed pan locking, in particular to a bed pan locking mechanism of a transport type incubator. Background Art

[0002] The neonatal incubator consists of a box body and a cover body, with a bed tray inside. The internal air is regulated by the principle of thermal convection to create an excellent environment with suitable air, suitable temperature and humidity, warmth and comfort, similar to the mother's womb, so as to cultivate and care for the baby. Newborns sometimes need to be moved to a new room or transferred for examination. In this case, the newborn can be safely transported using a transport incubator.

[0003] In existing neonatal incubators, most of the bed trays are fixed. When placing a neonate in or transferring it out of the incubator, most of the time, the window door of the incubator is opened. However, due to the limited space of the incubator, medical staff often need to bend over or reach into the incubator to operate, which may make the operation not smooth due to insufficient space, thereby increasing the difficulty of operation;

[0004] In addition, some bed trays are installed on the incubator via tracks. Such incubators generally adopt a single-side window design. During transportation, if the side window is not locked, the bed tray is at risk of sliding out, which will not only disturb the newborn but also pose a great safety hazard. In view of this, we propose a bed tray locking mechanism for a transport incubator. Summary of the invention

[0005] The object of the present invention is to provide a transport-type incubator bed tray locking mechanism to solve the problems raised in the above-mentioned background technology.

[0007] The sliding mechanism is provided with a protection auxiliary mechanism. When the sliding mechanism extends out of the box, the sliding mechanism moves to drive the protection auxiliary mechanism to rise for protection. When the sliding mechanism is located inside the box, the protection auxiliary mechanism contracts to assist the fixing mechanism in locking the sliding mechanism.

[0008] As a further improvement of the technical solution, the sliding mechanism at least includes a bed body slidably connected to the bracket, and the bed body is arranged inside the box body.

[0009] As a further improvement of the technical solution, the fixing mechanism at least includes two driving rods rotatably connected to the inner wall of the bracket, and the two driving rods are symmetrically arranged, one side of the driving rods is arranged through the outer wall of the bracket, and the two driving rods are fixedly connected to the limiting blocks, the bracket is provided with two through grooves, and the two limiting blocks are respectively located in the adjacent through grooves, and the bottom of the bed body is symmetrically provided with two card slots;

[0010] The two through slots and the clamping slots are symmetrically arranged, and the clamping slots are respectively located directly above the adjacent through slots.

[0011] As a further improvement of the present technical solution, the protective auxiliary mechanism includes at least a protective plate slidably connected to one side of the bed, both sides of the protective plate are rotatably connected with rollers, the inner wall of the bracket is fixedly connected to two trapezoidal blocks, and the two trapezoidal blocks are symmetrically arranged, and the rollers are rollingly connected to the trapezoidal blocks.

[0012] As a further improvement of the technical solution, the protective auxiliary mechanisms are provided in two groups, and are symmetrically arranged on both sides of the bed with the central axis of the bed as a reference.

[0013] As a further improvement of the technical solution, a groove is provided on one side of the two protective plates close to the bed body, and a fixed block is fixedly connected to one side of the bed body close to the groove. A No. 2 return spring is fixedly connected to the two fixed blocks, and the other side of the No. 2 return spring is fixedly connected to the inner wall of the groove.

[0014] As a further improvement of the technical solution, connecting rods are fixedly connected between each of the trapezoidal blocks, and rotating rods are rotatably connected to the connecting rods. One side of the rotating rod is located below the limit block, and the other side of the rotating rod is flush with the trapezoidal block.

[0015] As a further improvement of the technical solution, two No. 1 return springs are fixedly connected to the bottom of the bracket, and the side of the No. 1 return spring away from the bracket is fixedly connected to the adjacent limit block.

[0016] As a further improvement of the technical solution, two sliding grooves are provided on the bracket, and sliders are slidably connected in the sliding grooves, and the sliders are fixedly connected to the bottom of the bed.

[0017] As a further improvement of the technical solution, both sides of the box body are rotatably connected with box doors, and the outer wall of the bracket is fixedly connected with two automatic locks for fixing the driving rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the locking mechanism of the transport incubator bed tray, two driving rods are manually rotated to drive the limit block to rotate, so that after the limit block is moved out of the slot, the bed body is manually pulled out from the inside of the box, providing medical staff with a wider and more comfortable operating area, so that medical staff do not need to bend down or reach into the incubator to operate, and can operate more easily and conveniently when placing or caring for newborns, thereby improving work efficiency.

[0020] 2. In the locking mechanism of the bed tray of the transport incubator, when the bed is inside the box, two limit blocks are provided to fix both sides of the bed at the same time, ensuring the stability of the bed when it is inside the box. Even if the box door is not locked, the bed can always be fixed inside the box under the limit of the limit block; when the bed is outside the box, one side of the bed can be locked by the limit block to prevent the bed from sliding back into the box, thereby improving the convenience during operation.

[0021] 3. In the locking mechanism of the bed pan of the transport incubator, when the bed is moved out of the box, the protective plate is driven to rise upward, thereby enclosing both sides of the bed to form a relatively safe area, reducing the impact of external factors on the newborn; when the bed is retracted into the box, the protective plate moves elastically, squeezing the rotating rod so that the rotating rod can resist the limit block, making the limit block more stably connected in the slot, further improving the stability of the bed when it is inside the box.

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 9 As shown, this embodiment provides a locking mechanism for a transport incubator bed tray, including a bracket 100, on which a box 110 is fixedly mounted. The box 110 is made of a transparent material, which is convenient for medical staff to observe newborns. A sliding mechanism 200 is provided inside the box 110. When medical staff take or put, the sliding mechanism 200 slides out of the box 110, providing a wider and more comfortable operating area for medical staff, without the need for medical staff to bend down or reach into the incubator to operate, thereby improving work efficiency. A fixing mechanism 300 is provided inside the bracket 100, which is used to limit and fix the sliding mechanism 200, thereby ensuring the stability of the sliding mechanism 200 inside the box 110;

[0039] A protective auxiliary mechanism 400 is provided on the sliding mechanism 200. When the sliding mechanism 200 extends out of the box body 110, the sliding mechanism 200 moves to drive the protective auxiliary mechanism 400 to rise for protection, and the two sides of the sliding mechanism 200 are enclosed to form a relatively safe environment to reduce the impact of external factors on the newborn. When the sliding mechanism 200 is located inside the box body 110, the protective auxiliary mechanism 400 contracts to assist the fixing mechanism 300 in locking the sliding mechanism 200, so that the fixing mechanism 300 on the sliding mechanism 200 is more stably fixed.

[0040] In the existing neonatal incubators, most of the bed trays are fixed. When placing a neonate in the incubator or transferring it out of the incubator, most of the time, the window door of the incubator is opened. However, due to the limitation of the space of the incubator, medical staff often need to bend over or reach into the incubator to operate, which may make the operation not smooth due to insufficient space, thereby increasing the difficulty of operation; therefore, a sliding mechanism 200 is provided, and when it is necessary to care for, place or transfer the neonate, the sliding mechanism 200 is pulled out from the inside of the box 110, which can provide a more open and comfortable operating area for medical staff, so that medical staff do not need to bend over or reach into the incubator to operate, and can operate more easily and conveniently when placing or caring for the neonate, thereby improving work efficiency;

[0041] In addition, some of the bed trays are installed with the incubator by rails. Such incubators generally adopt a single-side window design. During the transportation process, if the side window is not locked, the bed tray is at risk of sliding out, which will not only disturb the newborn, but also pose a great safety hazard. Therefore, a sliding mechanism 200 and a fixing mechanism 300 are provided. When the sliding mechanism 200 is located inside the box 110, the fixing mechanism 300 can lock it in both directions to ensure the stability of the sliding mechanism 200 when it is located inside the box 110. Even if the box door 111 is not locked, the sliding mechanism 200 can always be fixed inside the box 110 under the limit of the fixing mechanism 300. Moreover, when the sliding mechanism 200 is pulled out from the box 110, one side of the sliding mechanism 200 can be locked by the fixing mechanism 300 to prevent the sliding mechanism 200 from sliding back into the box 110, thereby improving the convenience during operation.

[0042] And when the sliding mechanism 200 is moved out from the inside of the box 110, it can drive the protective auxiliary mechanism 400 to rise upward, so that when the sliding mechanism 200 is located outside the box 110, the protective auxiliary mechanism 400 can enclose both sides of the sliding mechanism 200 to form a relatively safe area, reducing the impact of external factors on the newborn, and can also increase the sense of security of medical staff when performing operations such as caring for and examining the newborn, so that various operations can be performed more calmly, which helps to improve the accuracy and efficiency of the operation. When the sliding mechanism 200 is located inside the box 110, the protective auxiliary mechanism 400 can provide additional pressure to the fixing mechanism 300, so that the fixing mechanism 300 is more stable when fixing the sliding mechanism 200.

[0043] In order to facilitate medical staff to care for or place newborns, such as Figure 5As shown, the specific structure of the sliding mechanism 200 is further disclosed. The sliding mechanism 200 at least includes a bed 210 slidably connected to the bracket 100, and the bed 210 is arranged inside the box 110. When the newborn needs to be placed inside the box 110, the bed 210 is slid out from the box 110, thereby providing a wider and more comfortable operating area for medical staff, so that the medical staff does not need to bend down significantly or reach into the incubator to operate, and can operate more easily and conveniently when placing the newborn, thereby improving work efficiency.

[0044] Considering the need to ensure the stability of the bed 210 inside the box 110, Figure 3-Figure 4 and Figure 7 As shown, the specific structure of the fixing mechanism 300 is further disclosed. The fixing mechanism 300 at least includes two driving rods 310 rotatably connected to the inner wall of the bracket 100, and the two driving rods 310 are symmetrically arranged. One side of the driving rods 310 is arranged through the outer wall of the bracket 100. The two driving rods 310 are fixedly connected to the limiting blocks 311. The two driving rods 310 and the limiting blocks 311 are arranged to lock the two sides of the bed 210, thereby improving the stability of the bed 210 inside the box 110. Two through grooves are provided on the bracket 100, and the two limiting blocks 311 are respectively located in the adjacent through grooves. Two card slots 312 are symmetrically provided at the bottom of the bed 210;

[0045] The two through slots and the clamping slot 312 are symmetrically arranged, and the clamping slots 312 are respectively located directly above the adjacent through slots. The limiting block 311 passes through the through slots and is clamped into the inside of the clamping slot 312 .

[0046] When the bed 210 is located inside the box 110, the limit block 311 is engaged with the slot 312, thereby limiting the movement of the bed 210, thereby avoiding the risk of the bed 210 sliding out of the box 110 when the bracket 100 is transported;

[0047] When the bed body 210 needs to be pulled out from the box body 110, the driving rod 310 is manually rotated to drive the limit block 311 to rotate, so that the limit block 311 is moved out of the slot 312, so that the limit block 311 no longer engages and limits the slot 312, making it easier for the staff to pull the bed body 210 out of the box body 110.

[0048] In order to improve the safety of placing a newborn on the bed 210, Figure 5 and Figure 6As shown, the specific structure of the protection auxiliary mechanism 400 is further disclosed. The protection auxiliary mechanism 400 at least includes a protection plate 410 slidably connected to one side of the bed body 210, and both sides of the protection plate 410 are rotatably connected to rollers 411. The inner wall of the bracket 100 is fixedly connected to two trapezoidal blocks 412, and the two trapezoidal blocks 412 are symmetrically arranged. The rollers 411 are rollingly connected to the trapezoidal blocks 412. When the bed body 210 is moved out of the box body 110, the protection plate 410 is driven to move. At this time, the protection plate 410 and the trapezoidal blocks 412 are connected. 12 is squeezed, thereby driving the protective plate 410 to slide on the bed body 210. When the bed body 210 is located outside the box body 110, the protective plate 410 is in a raised state, so that the protective plate 410 is located above the bracket 100, and the bed body 210 is enclosed to form a relatively safe area, which reduces the impact of external factors on the newborn, and can increase the sense of security of medical staff when performing operations such as nursing and examination on the newborn, so that various operations can be performed more calmly, which helps to improve the accuracy and efficiency of the operation.

[0049] Considering the need to further improve the protection effect of the protection auxiliary mechanism 400, as Figure 2 As shown, two groups of protective auxiliary mechanisms 400 are provided, and are symmetrically arranged on both sides of the bed 210 with the central axis of the bed 210 as a reference. When two groups of protective auxiliary mechanisms 400 are provided, when the bed 210 is located outside the box 110, the protective plate 410 is raised to enclose both sides of the bed 210 to form a relatively safe area, which effectively blocks the possibility of the newborn baby rolling down from both sides of the bed 210 and greatly reduces the risk of injury to the newborn baby.

[0050] Considering that after the bed 210 is put into the box 110, the protective plate 410 needs to be reset and moved. Figure 6 and Figure 8-Figure 9 As shown, grooves are provided on one side of the two protective plates 410 close to the bed body 210, and a fixing block 420 is fixedly connected to the one side of the bed body 210 close to the groove. A No. 2 return spring 421 is fixedly connected to the two fixing blocks 420, and the other side of the No. 2 return spring 421 is fixedly connected to the inner wall of the groove. When the bed body 210 is moved out of the box body 110, the fixing block 420 drives the protective plate 410 to slide on the bed body 210, thereby squeezing the No. 2 return spring 421. After the bed body 210 is retracted into the box body 110, the No. 2 return spring 421 restores the deformation force, drives the protective plate 410 to return and move, and the protective plate 410 moves downward and is retracted into the bracket 100.

[0051] When the protective plate 410 is retracted into the bracket 100, the stability of the fixing block 311 to the card slot 312 can be further improved by resetting the protective plate 410. Figure 4 and Figure 7As shown, connecting rods 500 are fixedly connected between each of the trapezoidal blocks 412, and rotating rods 510 are rotatably connected to the connecting rods 500. One side of the rotating rod 510 is located below the limit block 311, and the other side of the rotating rod 510 is flush with the trapezoidal block 412. When the No. 2 return spring 421 drives the protective plate 410 to return and move downward, the side of the rotating rod 510 located below the protective plate 410 is squeezed to drive the rotating rod 510 to move downward, thereby driving the rotating rod 510 to rotate on the connecting rod 500, so that the side of the rotating rod 510 close to the limit block 311 rotates upward and presses against the limit block 311, so that the limit block 311 is more stably connected to the card slot 312. In special circumstances such as transportation, the possibility of shaking or displacement of the bed 210 can be reduced, ensuring that the newborn is always in a stable environment.

[0052] Considering the need to ensure the stability of the limit block 311 being engaged in the slot 312, as shown in FIG. Figure 7 As shown, two No. 1 return springs 313 are fixedly connected to the bottom of the bracket 100, and the side of the No. 1 return spring 313 away from the bracket 100 is fixedly connected to the adjacent limit block 311. After the bed 210 is located inside the box 110 or has been pulled out from the bed 210, the drive rod 310 is manually released, and the limit block 311 is driven to reset and move under the force of the No. 1 return spring 313 to restore the deformation, so that the limit block 311 is snapped into one of the slots 312. The bed 210 can be locked by the limit block 311, thereby ensuring the stability of the bed 210 when it is inside the bed 210 and preventing the bed 210 from sliding back into the box 110 when it is outside the box 110.

[0053] In order to ensure the clarity of the movement of the bed 210, Figure 3 and Figure 6 As shown, two slide grooves 220 are provided on the bracket 100, and sliders 221 are slidably connected in the slide grooves 220, and the sliders 221 are fixedly connected to the bottom of the bed 210. When the bed 210 slides inside the box 110, the sliders 221 are driven to slide inside the slide grooves 220. The provision of the slide grooves 220 and the sliders 221 not only provides guidance for the movement of the bed 210, but also avoids the bed 210 from being pulled out of the box 110, so that the bed 210 can only move limitedly inside the box 110, and the bed 210 will not be separated from the box 110, thereby ensuring the safety of the newborn.

[0054] Considering the flexibility of the bed 210 when it is pulled out from the box 110, Figure 1As shown, both sides of the box body 110 are rotatably connected with the box door 111, so that the bed body 210 can be pulled out from both sides of the box body 110. In different usage scenarios and space layouts, medical staff can choose to pull out the bed body 210 from the left or right side according to actual conditions, thereby improving the flexibility of operation; the outer wall of the bracket 100 is fixedly connected with two automatic locks for fixing the drive rod 310. The automatic locks are composed of a latch body, a No. 3 reset spring, etc. When the button is pressed, the button will push the latch body and compress the No. 3 reset spring. When the button is released, the elastic force of the No. 3 reset spring will cause the latch to pop out, and through the action of the spring force, the pin head can automatically return to its position and self-lock. This is a prior art and will not be elaborated here.

[0055] Working principle: when it is necessary to take in or put in a newborn, first open the box door 111 and the lock on one side, then manually press to unlock the automatic lock, and then manually rotate the driving rod 310 to drive the limit block 311 to rotate. At this time, the No. 1 return spring 313 is compressed and deformed, and the limit block 311 rotates, so that the limit block 311 moves out of the slot 312, and then press the automatic lock to lock the limit block 311 to limit the rotation. After one of the limit blocks 311 is moved out of the slot 312 and fixed in the limit position, the same operation is performed to move the other limit block 311. The support frame 310 is moved out of the card slot 312, and at the same time, the bed body 210 is manually pulled to be pulled out of the box body 110, and then the driving rod 310 is manually released. Under the force of the No. 1 return spring 313 to restore the deformation, the limit block 311 is driven to return and move, so that the limit block 311 is clamped into one of the card slots 312, so that after the bed body 210 is moved out of the box body 110, the limit block 311 can lock the bed body 210 to prevent the bed body 210 from sliding back into the box body 110, thereby improving the convenience during operation;

[0056] When the bed 210 is moved out of the box 110, the protective plate 410 is driven to move. At this time, the protective plate 410 is squeezed with the trapezoidal block 412, and the fixed block 420 drives the protective plate 410 to slide on the bed 210. At this time, the No. 2 return spring 421 is compressed and deformed. When the bed 210 is located outside the box 110, the protective plate 410 is in a raised state. At this time, the protective plate 410 is located above the bracket 100, and the two sides of the bed 210 are enclosed to form a relatively safe area, which reduces the impact of external factors on the newborn, and can increase the sense of security of medical staff when performing operations such as nursing and examination on the newborn, so that various operations can be performed more calmly, which helps to improve the accuracy and efficiency of the operation;

[0057] When the bed body 210 is retracted into the box body 110, the force of the No. 2 return spring 421 to restore the deformation drives the protective plate 410 to return and move, and the protective plate 410 moves downward and is retracted into the bracket 100, thereby squeezing the side of the rotating rod 510 located below the protective plate 410, driving the rotating rod 510 to move downward, and then driving the rotating rod 510 to rotate on the connecting rod 500, so that the side of the rotating rod 510 close to the limit block 311 rotates upward and presses against the limit block 311, so that the limit block 311 is more stably connected in the slot 312, further improving the stability of the bed body 210 when it is located inside the box body 110.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
