Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a bed body mechanism and an infant radiation warming table. Background Art

[0002] Infant radiant warming table refers to a nursing and warming device specially used for newborns, premature infants, critically ill infants, and weak infants. In clinical practice, "infant radiant warming table" is also called "radiant neonatal rescue table" and "infant radiant warming table". It provides a suitable environment for premature infants and sick infants, and is used for infusion, rescue, hospitalization observation, etc. of premature infants, critically ill infants, and weak infants.

[0003] There are currently two ways to achieve bed tilting in the infant radiant warming table. One is electric control, which uses the movement of the push rod motor to tilt the bed; the other is manual mechanical control, which uses a rotating shaft mechanical structure to achieve on-demand and off-the-shelf operation. Among the manual tilting structural designs on the market, gas springs are used to assist, making manual tilting more labor-saving. However, there is a possibility of gas spring failure, which may lead to danger, and the most important thing for medical devices is safety. Utility Model Content

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] like Figure 1-2 As shown, in an embodiment of a bed structure, the bed structure includes a base 1, a bed body 2, a thrust assembly 3, a support rod 4 and a locking assembly 5. The bed body 2 is rotatably connected to the base 1. One end of the thrust assembly 3 is rotatably connected to the base 1, and the other end can abut against the bed body 2, and the thrust assembly 3 is used to apply thrust to the bed body 2. One end of the support rod 4 is rotatably connected to the base 1, and the other end is rotatably connected to the bed body 2, so that it can move with the rotation of the bed body 2. The locking assembly 5 can limit the movement of the support rod 4, thereby maintaining the position of the bed body 2 relative to the base 1.

[0034] In this embodiment, when the bed body 2 is rotating, the thrust assembly 3 can facilitate the rotation of the bed body 2 by applying force to the bed body 2, and by adding the support rod 4 and the locking assembly 5, the support rod 4 can move with the rotation of the bed body 2, and the locking assembly 5 can limit the movement of the support rod 4, thereby positioning the bed body 2 relative to the base 1, so that even if the thrust assembly 3 fails, the bed body 2 can be supported, achieving a safe and stable effect, and solving the technical problems of unsafe and unstable existing bed structures when tilted.

[0035] It is understandable that the locking assembly 5 can limit the further movement of the support rod 4 by clamping, locking, etc., so that the support rod 4 can play a role in supporting the bed body 2 and maintain the position of the bed body 2 relative to the base 1.

[0036] It should be noted that when the bed body 2 needs to be rotated, the locking assembly 5 needs to release the restriction on the support rod 4 .

[0037] In one embodiment of the bed mechanism, the bed mechanism also includes a limiting component 6, which can move relative to the bed body 2. The limiting component 6 has a first locking position close to the bed body 2 and a first unlocking position away from the bed body 2 in its moving path. When the limiting component 6 is in the first locking position, it can limit the thrust component 3 from applying force to the bed body 2. During the movement of the limiting component 6 from the first locking position to the first unlocking position, the limiting component 6 can release the restriction on the thrust component 3 so that the thrust component 3 can apply force to the bed body 2.

[0038] In the present embodiment, specifically, one end of the thrust assembly 3 is rotatably connected to the base 1, and the other end is rotatably connected to the bed body 2. The thrust assembly 3 can be specifically a gas spring, which can always generate thrust during the working process, so as to achieve a boosting effect. In the present embodiment, a limiting assembly 6 is provided to limit the thrust of the thrust assembly 3. By providing the limiting assembly 6, for the convenience of understanding, the limiting assembly 6 is located in the first locking position corresponding to the horizontal position of the bed body 2 as an example. When the limiting assembly 6 is located in the first locking position, the thrust of the thrust assembly 3 can be prevented from being transmitted to the bed body 2 by supporting the force-applying end of the thrust assembly 3. When the limiting assembly 6 leaves the first locking position, the thrust of the thrust assembly 3 can act on the bed body 2, so as to achieve a boosting effect and facilitate the rotation of the bed body 2. When the bed body 2 needs to be reset to the horizontal position, the limiting assembly 6 can be reset to the first locking position to limit the force applied by the thrust assembly 3 to the bed body 2, so as to avoid the thrust applied by the thrust assembly 3 to the bed body 2 becoming an obstacle to the reset of the bed body 2.

[0039] In one embodiment of the bed mechanism, the locking assembly 5 can move relative to the bed body 2. The locking assembly 5 has a second locking position capable of limiting the movement of the support rod 4 and a second unlocking position away from the support rod 4 in its moving path. When the locking assembly 5 is in the second unlocking position, the support rod 4 can move along with the rotation of the bed body 2. The bed mechanism also includes a transmission member 7, one end of which is connected to the limiting assembly 6 and the other end is connected to the locking assembly 5. The transmission member 7 is used to transmit the movement of the limiting assembly 6 to the locking assembly 5, so that the movement of the limiting assembly 6 from the first locking position to the first unlocking position can drive the locking assembly 5 to move from the second locking position to the second unlocking position.

[0040] In this embodiment, by setting up the transmission member 7, the limiting component 6 and the locking component 5 can be connected together, so that the operator only needs to operate the limiting component 6 to release the restriction on the elastic component and the lock of the support rod 4, which is simple to operate.

[0041] In one embodiment of the bed structure, the base 1 is rotatably connected to a limiting sleeve 9, the support rod 4 passes through the limiting sleeve 9, and can drive the limiting sleeve 9 to rotate during the movement. The locking assembly 5 can limit the rotation of the limiting sleeve 9 when it is in the second locking position.

[0042] In this embodiment, the limit sleeve 9 is provided to facilitate the rotation of the support rod 4. It can be understood that when the support rod 4 passes through the limit sleeve 9 and rotates, the length of the support rod 4 extending out of the limit sleeve 9 varies. This can increase the degree of freedom of the support rod 4 and avoid getting stuck. In addition, the locking assembly 5 limits the rotation of the limit sleeve 9. For example, the locking assembly 5 can clamp or jam the limit sleeve 9 to prevent the limit sleeve 9 from rotating. When the limit sleeve 9 cannot rotate, the support rod 4 is restricted and cannot rotate either.

[0043] In one embodiment of the bed mechanism, a groove 91 is provided on one side of the limiting sleeve 9 relative to the locking assembly 5 to expose the support rod 4. When the locking assembly 5 is in the second locking position, it extends into the groove 91 and engages with the support rod 4, and the locking assembly 5 contacts the side wall of the groove 91.

[0044] Different from the previous locking forms, in this embodiment, when the locking assembly 5 is located in the second locking position, it not only limits the rotation of the limit sleeve 9 by extending into the groove 91, but also engages with the support rod 4. In this way, it can more stably limit the rotation of the support rod 4, that is, stabilize the position of the support rod 4.

[0045] In one embodiment of the bed structure, the support rod 4 is provided with a first engaging portion, and the locking assembly 5 is provided with a second engaging portion that can engage with the first engaging portion. When the locking assembly 5 is in the second locking position, the second engaging portion engages with the first engaging portion and is locked.

[0046] In this embodiment, by arranging the support rod 4 and the locking assembly 5 in an engageable manner, a snap-fitting effect can be achieved when engaged. At this time, the rotation tendency of the limit sleeve 9 will also be limited by the force exerted by the engagement. The restricted rotation of the limit sleeve 9 will also react on the support rod 4, making the support rod 4 unable to rotate. It can be understood that the engagement of the locking assembly 5 with the support rod 4 and the abutment of the locking assembly 5 with the side wall of the groove 91 of the limit sleeve 9 are formed at the same time and have a mutual limiting effect. The whole structure thus constructed will make the support rod 4 in that position, further achieving a safer and more stable effect.

[0047] Specifically, the support rod 4 may be a threaded screw, and the first engaging portion is a thread thereon, and correspondingly, the second engaging portion on the locking component 5 is also a thread.

[0048] In an embodiment of a bed mechanism, the locking assembly 5 includes an elastic member 51 and a claw 52. The elastic member 51 has an initial state and an energy storage state. The claw 52 is connected to the transmission member 7 and to the elastic member 51. The claw 52 can convert the elastic member 51 from the initial state to the energy storage state under the movement driven by the transmission member 7. When the elastic member 51 is in the initial state, the claw 52 is at least partially accommodated in the groove 91 and is engaged with the support rod 4.

[0049] In this embodiment, specifically, one end of the elastic member 51 is connected to the claw 52, ​​and the other end is connected to the limiting sleeve 9 or the support rod 4. In the initial state, the claw 52 and the elastic member 51 are both accommodated in the groove 91. When the transmission member 7 drives the claw 52 away from the support rod 4, the elastic member 51 will be stretched and converted to an energy storage state. Further, when the external force applied to the transmission member 7 is removed, the claw 52 will re-extend into the groove 91 under the action of the elastic member 51, forming an engagement with the support rod 4 and a clamping connection with the limiting sleeve 9.

[0050] In one embodiment of the bed structure, the axial direction of the support rod 4 is parallel to the thrust direction of the thrust assembly 3. That is, the support rod 4 and the thrust assembly 3 are parallel. In this embodiment, by setting the two to be parallel, the thrust and the support force can also be kept parallel, which can save effort and stabilize the rotation process.

[0051] In an embodiment of the bed mechanism, a protrusion 61 is provided on the limiting assembly 6 , and the bed mechanism further comprises a limiter 8 , which is located on the movable path of the limiting assembly 6 and can limit the movable travel of the limiting assembly 6 by abutting against the protrusion 61 .

[0052] In combination with the previous embodiments, it can be understood that the limiting component 6 is an active component. The operator can release the restrictions of the thrust component 3 and the support rod 4 by pulling the limiting component 6, so that the bed body 2 can rotate. Releasing the restrictions of the thrust component 3 and the support rod 4 is a state. When the limiting component 6 moves to a certain position, it does not need to move further. For this reason, the present embodiment provides a limit member 8. By providing the limit member 8 to abut the protrusion 61 on the limiting component 6, it can serve to remind the operator that there is no need to further pull the limiting component 6, thereby reducing unnecessary operations.

[0053] Specifically, the limiting component 6 can be a rod-shaped structural member, which can be easily pulled by the operator. In order to facilitate the movement direction of the limiting component 6, a guide hole can be set to allow the limiting component 6 to pass through, wherein the limiting member 8 can be set on the outer wall forming the guide hole. The guide hole can be set on the bed body 2, and correspondingly, the limiting member 8 can be connected to the bed body 2. Of course, the limiting member 8 can also be set on the base 1. The specific position is not limited, as long as the limiting can be achieved.

[0054] The utility model also relates to an infant radiation warming table, comprising the bed body mechanism in the foregoing embodiment, the infant radiation warming table further comprises a radiation heating mechanism, and the radiation heating mechanism is used for radiantly heating the bed body 2.

[0055] By adopting the bed body mechanism in the previous embodiment, the bed body 2 can be stably rotated, which is convenient for the operator to adjust the tilt angle according to the situation, thereby improving safety.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
