Description

Technical Field

[0001] This utility model relates to an oxygen supply device for an infant radiant warmer, belonging to the technical field of oxygen supply devices. Background Technology

[0002] In the field of clinical neonatal care, radiant warmers are commonly used medical devices in operating rooms and neonatal wards. Their main function is to provide newborns with a constant, warm environment, facilitating nursing and treatment procedures for medical staff. However, current radiant warmers generally lack a module for direct connection to the hospital's central oxygen supply system. When a newborn requires oxygen therapy due to their condition, medical staff face the following technical challenges:

[0003] Currently, the oxygen inlets of hospital central oxygen supply systems are typically fixed on the equipment strip on the operating room wall or near the mother's head, while the conventional placement of infant radiant warmers is usually on the side or back of the operating table. If a central oxygen supply system is directly connected via an oxygen tubing, the radiant warmer needs to be moved near the oxygen inlet, or the oxygen supply equipment (such as oxygen cylinders or terminals) needs to be transported next to the radiant warmer. However, operating rooms have a compact layout and numerous pieces of equipment. Radiant warmers are large and need to maintain stable operation; frequent movement can cause temperature fluctuations in the incubator, affecting the newborn's vital signs. Furthermore, the oxygen tubing has a limited length; forcibly dragging it can lead to tangling, kinking, or even detachment, posing a safety hazard of interrupted oxygen supply. On the other hand, moving oxygen supply equipment not only increases the workload of medical staff but also poses secondary risks due to collisions or tipping during movement, especially in emergency rescue scenarios where inconvenience directly impacts treatment efficiency.

[0009] The aforementioned oxygen supply device for an infant radiant warmer includes a quick-connect mechanism comprising a first annular groove on the side of a second connecting pipe, a connecting groove inside the first connecting pipe, a second annular groove on the outside of the first connecting pipe, and a movable ring, the movable ring being slidably connected to the first connecting pipe; the movable ring having a first convex ring inside, the inner end face of the first convex ring abutting against the second annular groove; the first annular groove having multiple through grooves circumferentially distributed thereon, each through groove containing a ball bearing; the through grooves corresponding to the first annular groove; and the two sides of the first annular groove being sloped surfaces to guide the ball bearings to slide.

[0011] The aforementioned oxygen supply device for an infant radiant warmer has a sealing ring on the inner end face of the connecting groove.

[0012] The aforementioned oxygen supply device for an infant radiant warmer includes an anti-fall mechanism comprising connecting straps on the left and right sides of the mounting block.

[0013] The aforementioned oxygen supply device for an infant radiant warmer has a pressure gauge installed on the second connecting pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this invention, the mounting block is first initially fixed to the upright of the radiant table using an anti-fall mechanism. Then, an adsorption mechanism adheres the mounting block to the surface of the upright to prevent it from slipping. Next, a quick-connect mechanism connects the first and second connecting pipes. One end of the flexible hose is connected to the first connection port, and the other end is connected to the oxygen generation device. The second connection port is connected to the infant's nasal cannula, oxygen mask, or other equipment via a pipeline. An oxygen flow monitoring mechanism monitors the oxygen supply to prevent interruption of oxygen output. Therefore, this invention allows for easy installation on radiant tables without oxygen supply equipment to meet the oxygen needs of infants, offering advantages such as quick installation and simple operation.

[0016] 2. In this utility model, when using the adsorption mechanism to adsorb the mounting block onto the surface of the pole, first, the rear end face of the mounting block is pressed tightly against the pole, so that the suction cup contacts the pole. Then, the L-shaped rod is rotated so that the end face of the L-shaped rod abuts against the mounting block. Through the lever principle, the connecting rod is pulled outward. At this time, the internal air pressure of the suction cup decreases due to deformation, forming a negative pressure state, thus firmly adsorbing onto the surface of the pole. When it is necessary to remove the mounting block, the L-shaped rod is rotated in the opposite direction. The end face of the L-shaped rod does not abut against the surface of the mounting block. Under the action of the first spring, the connecting rod is reset. The connecting rod drives the suction cup to automatically reset, and the internal air pressure of the suction cup returns to normal pressure, so the mounting block can be easily removed.

[0017] 3. In this utility model, when connecting the first connecting pipe and the second connecting pipe through the quick-connect mechanism, the moving ring is first moved towards the mounting block so that the first convex ring on its inner side is no longer in contact with the ball, that is, the first convex ring no longer presses down on the top of the ball, leaving radial movement space for the ball. Then, the second connecting pipe is inserted into the connecting groove. During the insertion process, the ball moves outward due to the collision with the outer wall of the second connecting pipe. At this time, part of the ball enters the second ring groove, and the remaining part is still located in the through groove. After the insertion is completed, the first ring groove and the through groove are aligned. The moving ring is released, and the moving ring is reset under the elastic action of the third spring. The first convex ring abuts against the ball and moves it inward, so that the ball is simultaneously locked into the fitting gap between the through groove and the first ring groove, forming a bidirectional limit, thereby locking the first connecting pipe and the second connecting pipe.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] Example: An oxygen supply device for an infant radiant warmer, configured as follows Figure 1-5As shown, the device includes a mounting block 1 made of high-strength plastic, which is lightweight and sturdy, providing a stable support structure for the entire device. A suction mechanism 2 is symmetrically arranged on the rear side of the mounting block 1, which securely fixes the mounting block 1 to the surface of the upright, preventing the device from slipping and ensuring the stability of the oxygen supply process. The front end of the mounting block 1 has a first connecting pipe 3, which contains a first oxygen delivery channel 4. The lower end of the first connecting pipe 3 has a first connecting port 5 that communicates with the first oxygen delivery channel 4. A flexible hose 6 is connected to the first connecting port 5, and the outer end of the flexible hose 6 is connected to the oxygen production equipment. A second connecting pipe 6 is connected to the outer end of the first connecting pipe 3. The second connecting pipe 7 is connected to an oxygen flow mechanism 8 at one end, which is used to monitor and regulate the oxygen flow rate. A quick-connect mechanism 9 is provided between the second connecting pipe 7 and the first connecting pipe 3, which enables a quick and stable connection between the first connecting pipe 3 and the second connecting pipe 7, facilitating the installation and disassembly of the device. The lower end of the oxygen flow mechanism 8 is provided with a second connection port 10, which is connected to equipment such as nasal cannulas and oxygen masks through a connecting pipe. The second connecting pipe 7 has a second oxygen delivery channel 11, which is connected to the first oxygen delivery channel 4 and the second connection port 10 respectively. The mounting block 1 is provided with an anti-drop mechanism 12 on its side. First, the mounting block 1 is initially fixed to the upright of the radiation table using the anti-fall mechanism 12. Then, the mounting block 1 is adsorbed onto the surface of the upright using the adsorption mechanism 2 to prevent the mounting block 1 from slipping. Next, the first connecting pipe 3 and the second connecting pipe 7 are connected using the quick-connect mechanism 9. Then, one end of the hose 6 is connected to the first connecting port 5, and the other end is connected to the oxygen generation equipment. The second connecting port 10 is connected to the infant's nasal oxygen cannula, oxygen mask, and other equipment through the pipeline. The oxygen flow rate is monitored by the oxygen flow mechanism 8 to prevent oxygen output interruption.

[0027] Preferably, such as Figure 3 and Figure 5As shown, the adsorption mechanism 2 includes circular grooves 20 symmetrically arranged on the rear side of the mounting block 1. A suction cup 21 is provided in the circular groove 20. The suction cup 21 is made of nitrile rubber, which has good elasticity and sealing properties, ensuring that the suction cup 21 is tightly attached to the surface of the pole. A disc 22 is provided at the inner end of the suction cup 21. The disc 22 is made of plastic, which is lightweight and has a certain strength. The disc 22 is used to press the end face of the suction cup 21 when the connecting rod 23 is reset by the first spring 25, so that the air pressure in the suction cup 21 can be quickly restored. A connecting rod 23 is provided at the inner end of the disc 22. The connecting rod 23 passes through the mounting block 1 and is rotatably connected to an L-shaped rod 24. The first spring 25 is located between the disc 22 and the inner end face of the circular groove 20 and surrounds the outside of the connecting rod 23. When using the adsorption mechanism 2 to attach the mounting block 1 to the surface of the pole, first press the rear end face of the mounting block 1 tightly against the pole, so that the suction cup 21 contacts the pole. Then rotate the L-shaped rod 24 so that the end face of the L-shaped rod 24 abuts against the mounting block 1. Through the lever principle, the connecting rod 23 is pulled outward. At this time, the internal air pressure of the suction cup 21 decreases due to deformation, forming a negative pressure state, thus firmly adsorbing onto the surface of the pole. When it is necessary to remove the mounting block 1, rotate the L-shaped rod 24 in the opposite direction. The end face of the L-shaped rod 24 does not abut against the surface of the mounting block 1. Under the action of the first spring 25, the connecting rod 23 is reset. The connecting rod 23 drives the suction cup 21 to automatically reset. The internal air pressure of the suction cup 21 returns to normal pressure, and the mounting block 1 can be easily removed.

[0028] Preferably, such as Figure 4 and Figure 5As shown, the oxygen flow mechanism 8 includes a base 30 fixedly connected to the second connecting pipe 7, and a second connecting port 10 located below the base 30. A first oxygen mask 31 and a second oxygen mask 32 are provided above the base 30, both made of transparent plastic. The transparency facilitates observation of the position of the internal oxygen float 35. The second oxygen mask 32 is located inside the first oxygen mask 31 and has an opening at its upper end. A third oxygen delivery channel 33 is provided inside the base 30, and the third oxygen delivery channel 33 is connected to the second oxygen mask 32 and the second oxygen delivery channel 11, respectively. The base 30 has multiple ventilation holes 34 located inside the first oxygen mask 31 and outside the second oxygen mask 32, and the ventilation holes 34 are connected to the second connecting port 10 and the interior of the first oxygen mask 31, respectively. An oxygen float 35 is placed inside the second oxygen mask 32, which can float in the oxygen flow and display the flow rate by balancing buoyancy with airflow pressure. The base 30 has a torsion control valve 36 on its side. The control end of the torsion control valve 36 extends between the vent 34 and the second connection port 10. The amount of oxygen passing through the valve is controlled by rotating it. A second spring 37 is provided on the inner side of the top of the first oxygen hood 31. The second spring 37 extends into the second oxygen hood 32. The second spring 37 is used to prevent the oxygen float 35 from rising rapidly and colliding with the first oxygen hood 31 due to excessive instantaneous oxygen flow, which could cause damage to the first oxygen hood 31. The second oxygen hood 32 has scale lines on its side. Oxygen enters from below the second oxygen hood 32 through the second connecting pipe 7, the second oxygen supply channel 11, and the third oxygen supply channel 33, and then enters the first oxygen hood 31 from above the second oxygen hood 32 before flowing out from the second connecting port 10 through the vent 34. During this process, the oxygen impacts the oxygen float 35 upward, generating upward dynamic pressure. The oxygen float 35 stabilizes at a certain height due to the balance between the dynamic pressure, buoyancy, and gravity. The position of the oxygen float 35 corresponds to the scale line, thus allowing for direct observation of the real-time oxygen flow rate.

[0029] Preferably, such as Figure 5 and Figure 6As shown, the quick-connect mechanism 9 includes a first annular groove 40 disposed on the side of the second connecting pipe 7, a connecting groove 41 disposed inside the first connecting pipe 3, a second annular groove 42 disposed on the outside of the first connecting pipe 3, and a moving ring 43. The moving ring 43 is slidably connected to the first connecting pipe 3. The moving ring 43 has a first convex ring 44 inside, and the inner end face of the first convex ring 44 abuts against the second annular groove 42. The first annular groove 40 has a plurality of through grooves 45 distributed circumferentially. The bottom of the through grooves 45 is bent inward so that the ball 46 cannot separate from the through groove 45, preventing the ball 46 from falling out. The through groove 45 is provided with a ball 46. The through groove 45 corresponds to the first annular groove 40. The two sides of the first annular groove 40 are set as inclined surfaces to guide the ball 46 to slide. The inclined surfaces prevent the ball 46 from getting stuck between the through groove 45 and the first annular groove 40 and being unable to move. A third spring 47 surrounds the outer side of the second annular groove 42, and the two ends of the third spring 47 are respectively connected to the inner side of the first convex ring 44 and the inner side of the second annular groove 42; the front end of the connecting groove 41 is provided with a third annular groove 48; the second connecting pipe 7 is provided with a second convex ring 49 located in front of the first annular groove 40, and the second convex ring 49 corresponds to the third annular groove 48. A sealing ring 50 is provided on the inner end face of the connecting groove 41 to enhance the sealing of the connection between the first connecting pipe 3 and the second connecting pipe 7. When connecting the first connecting pipe 3 and the second connecting pipe 7 via the quick-connect mechanism 9, the moving ring 43 is first moved towards the mounting block 1, so that the first convex ring 44 on its inner side is no longer in contact with the ball 46, that is, the first convex ring 44 no longer presses down on the top of the ball 46, leaving radial movement space for the ball 46. Then, the second connecting pipe 7 is inserted into the connecting groove 41. During the insertion process, the ball 46 is moved outward by the collision of the outer wall of the second connecting pipe 7. At this time, part of the ball 46 enters the second annular groove 42, and the remaining part is still located in the through groove 45. After the insertion is completed, the first annular groove 40 and the through groove 45 are aligned. The moving ring 43 is released, and the moving ring 43 is reset under the elastic action of the third spring 47. The first convex ring 44 abuts against the ball 46 and moves it inward, so that the ball 46 is simultaneously locked into the mating gap between the through groove 45 and the first annular groove 40, forming a bidirectional limit, thereby locking the first connecting pipe 3 and the second connecting pipe 7.

[0030] Preferably, such as Figure 1 and Figure 2 As shown, the anti-fall mechanism 12 includes connecting straps 60 on the left and right sides of the mounting block 1. One end of one connecting strap 60 is provided with a male buckle 61, and the other end of the other connecting strap 60 is provided with a female buckle 62, which cooperates with the male buckle 61. One connecting strap 60 is provided with an adjusting buckle 63. After the mounting block 1 is fixed to the end face of the radiation table pole, the connecting straps 60 on both sides are wrapped around the outside of the pole and connected to the male buckle 61 through the female buckle 62. The tightness is adjusted by adjusting the adjusting buckle 63, so that the mounting block 1 is initially fixed on the pole.

[0031] Preferably, such as Figure 1 and Figure 2 As shown, a pressure gauge is installed on the second connecting pipe 7, which can monitor the pressure during the oxygen delivery process in real time, ensuring the safety and stability of oxygen delivery.

[0032] Working principle:

[0033] First, using the connecting strap 60 of the anti-fall mechanism 12 and the male buckle 61 and female buckle 62, along with the adjusting buckle 63, the mounting block 1 is initially fixed to the radiation table pole. Then, the suction mechanism 2 is operated to make the suction cup 21 on the rear end face of the mounting block 1 adhere tightly to the pole. The L-shaped rod is rotated to pull the stainless steel connecting rod 23 through the lever principle, so that the suction cup 21 is deformed and forms a negative pressure to firmly adhere to the surface of the pole. If it needs to be removed, the L-shaped rod is rotated in the opposite direction, and the connecting rod 23 is reset under the action of the first spring 25, and the suction cup 21 returns to normal pressure. Oxygen generated by the oxygen generator enters the first oxygen delivery channel 4 of the first connecting pipe 3 through the first connection port 5 via the hose 6. The first connecting pipe 3 and the second connecting pipe 7 are connected by the quick-connect mechanism 9. The oxygen then enters the second oxygen delivery channel 11 of the second connecting pipe 7, and then enters from below the second oxygen mask 32 through the third oxygen delivery channel 33, impacting the oxygen float 35 upwards. When the dynamic pressure, buoyancy and gravity of the oxygen float 35 are balanced, it stabilizes at a certain height, and its position corresponds to the scale line on the side of the second oxygen mask 32, allowing for direct observation of the real-time oxygen flow rate. The oxygen flow rate can be adjusted by turning the control valve 36. Finally, the oxygen is delivered to the infant's nasal cannula, oxygen mask and other equipment through the pipeline via the vent 34 from the second connection port 10. At the same time, the pressure gauge on the second connecting pipe 7 monitors the oxygen pressure in real time to ensure the safe and stable delivery of oxygen, and the oxygen flow mechanism 8 continuously monitors the oxygen flow rate to prevent interruption of oxygen output.
