Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a newborn artificial skin puncher with adjustable aperture size. Background Technology

[0002] Non-invasive ventilators for newborns are typically used to support premature infants or babies with breathing difficulties. To ensure effective connection to the ventilator, airflow is usually delivered to the newborn's airway via a mask or nasal cannula. Because newborns' skin is delicate and easily compressed and damaged, especially when wearing a mask for extended periods, artificial skin pads are generally used under the nasal cannula in clinical practice to protect the infant's skin.

[0003] Currently, there are no artificial skin punchers specifically designed for newborns on the market. The commonly used punchers are those with fixed apertures, typically used for bookbinding. However, because newborns have different gestational ages and varying nostril sizes, using a fixed-aperture puncher may not accurately meet the specific needs of each newborn, leading to unnecessary pressure and friction, and causing redness, swelling, breakage, or abrasions to the nasal skin. Therefore, this invention proposes a newborn artificial skin puncher with adjustable aperture size to solve the aforementioned technical problems. Utility Model Content

[0004] In order to overcome the technical problems mentioned in the background art, the present invention provides a newborn artificial skin puncher with adjustable aperture size function.

[0005] The technical solution is as follows: A newborn artificial skin punch with adjustable aperture size includes a base, a slide block slidably connected to the upper end of the base, the slide block being driven by a driving component to move up and down, a switching block connected to the center of the slide block via a rotating rod, a dividing component arranged circumferentially around the outer periphery of the switching block, a pressure plate connected to the bottom surface of the slide block via a buffer component, a through groove provided at the lower part of the base, a conversion block rotatably connected within the through groove, a dividing hole arranged circumferentially around the outer periphery of the conversion block to cooperate with the dividing component, and the rotating rod... One end is fixed to the switching block, and the other end is rotatably connected to the slide. The rotating rods are symmetrically arranged around the switching block. One of the rotating rods is fixed to a square block. A rotating block is rotatably connected to the upper part of the base. A cross groove that mates with the square block is provided on the side of the rotating block near the square block. A movable groove is provided diagonally on the cross groove. A connecting rod is slidably connected in the movable groove. The connecting rod passes through the rotating block. A limit block is fixed to one end of the connecting rod near the center of the cross groove, and a counterweight is fixed to the other end. The rotating block is connected to the rotating shaft of the switching block through a transmission component.

[0006] Preferably, the dividing component includes threaded posts and dividing posts. The switching block and the conversion block are both rectangular in shape. Two threaded posts are fixed to each of the four outer surfaces of the switching block. Dividing posts are threadedly connected to the threaded posts. The shaft diameter and shaft spacing of any two dividing posts are different. Dividing holes corresponding to the dividing posts are provided on each of the four outer surfaces of the conversion block.

[0007] Preferably, it also includes a rotating handle, with the rotating handle fixedly connected to the side of the rotating block away from the square block. The transmission component includes a synchronous pulley and a synchronous belt. Synchronous pulleys are installed on the rotating block and the shaft of the conversion block, and the two synchronous pulleys are connected by a synchronous belt.

[0008] Preferably, a sliding groove is provided on the upper side of the base, and the slide block is slidably connected to the sliding groove. The driving component includes a hydraulic cylinder, which is installed on the top surface of the base, and the output shaft of the hydraulic cylinder is fixedly connected to the slide block.

[0009] Preferably, the buffer component includes a telescopic tube, a piston block, a piston rod, an elastic element, and a sealing ring. The slide is rectangular in shape, with piston holes at its four corners. A piston block is slidably connected to the piston hole in a sealed manner. A piston rod is fixed to the top surface of the piston block. A sealing ring is installed on the top surface of the piston hole. The piston rod passes through the sealing ring in a sealed manner. An elastic element is provided between the sealing ring and the piston block. The four corners of the slide are connected to the pressure plate through the telescopic tube. A connecting hole is provided on the bottom surface of the four corners of the slide, which connects the piston hole and the telescopic tube. The inside of the telescopic tube is filled with filler.

[0010] Preferably, the filler is hydraulic oil.

[0011] Preferably, magnets are installed on the sides of the two counterweights that are close to each other, and magnets are installed on the sides of the two limiting blocks that are far from each other. The rotating block is a magnetic component, and the counterweights and the rotating block are magnetically connected. The weight of the counterweights is greater than the attraction force generated by the two magnets.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model includes components such as a switching block, a dividing column, and a conversion block. When the dividing column needs to be adjusted, the rotating handle is rotated clockwise in multiples of 90 degrees. The rotating handle drives the rotating block to rotate, which in turn drives the limiting block to rotate. Since the upper limiting block is located in the cross groove, it will abut against the square block during rotation. Therefore, the upper limiting block will drive the square block to rotate together, which in turn drives the rotating rod to rotate. The rotating rod then drives the switching block to rotate together, allowing different dividing columns to be replaced to select the appropriate dividing column. When the rotating block rotates, it drives the synchronous wheel to rotate. The synchronous wheel drives another synchronous wheel to rotate via a synchronous belt, which in turn drives the conversion block to rotate. This ensures that the switching block and the conversion block rotate synchronously, thus ensuring that the dividing column always corresponds to the dividing hole and preventing the operator from forgetting to rotate the conversion block, which could lead to an operational accident.

[0014] 2. This utility model is equipped with buffer components and other components to prevent the newborn artificial skin from shaking during the cutting process, thereby causing incomplete cutting. Attached Figure Description

Detailed implementation mode

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation modes.

[0022] A neonatal artificial skin puncher with the function of adjusting the aperture size, as Figures 1-5 shown, includes a base 101. The base 101 is in the shape of a "C". On the upper side of the inner part of the base 101, a chute 1012 is provided. A sliding seat 102 is slidably connected in the chute 1012. The sliding seat 102 is driven by a driving component to move up and down. Specifically, the driving component includes a hydraulic cylinder 108. The hydraulic cylinder 108 is installed on the top surface of the base 101. The output shaft of the hydraulic cylinder 108 is fixedly connected to the sliding seat 102. The sliding seat 102 is in the shape of a "hui" character. At the center of the "hui" character of the sliding seat 102, a switching block 103 is connected by a rotating rod 106. The rotating rods 106 are symmetrically arranged with the switching block 103 as the center. One end of the rotating rod 106 is fixedly connected to the switching block 103, and the other end is rotatably connected to the sliding seat 102. A dividing component is arranged on the outer circumference of the switching block 103 along the circumferential direction. A through groove 1011 is provided at the lower part of the base 101. A conversion block 107 is rotatably connected in the through groove 1011. Dividing holes 1071 are provided on the outer circumference of the conversion block 107 along the circumferential direction and are matched with the dividing component;

[0023] A square block 201 is fixedly connected to one of the rotating rods 106. A rotating block 202 is rotatably connected to the outer side wall of the upper part of the base 101. A cross groove 2022 matched with the square block 201 is provided on one side of the rotating block 202 close to the square block 201. An activity groove 2021 is obliquely arranged diagonally with the center point of the cross groove 2022 as the center in the cross groove 2022. A connecting rod 204 is slidably connected in the activity groove 2021. The connecting rod 204 penetrates through the rotating block 202. One end of the connecting rod 204 close to the center of the cross groove 2022 is fixedly connected with a limiting block 203, and the other end is fixedly connected with a counterweight block 205. The counterweight block 205 is in the shape of an arc. The inner diameter of the counterweight block 205 is equal to the outer diameter of the rotating block 202. Among them, under the influence of gravity, the upper counterweight block 205 is closely attached to the outer diameter of the rotating block 202. Then, the upper limiting block 203 slides into the cross groove 2022. The rotating block 202 is connected with the rotating shaft of the conversion block 107 through a transmission component. Magnet sheets are installed on one side surface of the two counterweight blocks 205 close to each other. Magnet sheets are installed on one side surface of the two limiting blocks 203 far from each other. The rotating block 202 is a magnetic part. The counterweight block 205 is magnetically connected to the rotating block 202. The gravity of the counterweight block 205 is greater than the suction force generated by the two magnet sheets;

[0024] The dividing component includes threaded post 104 and dividing post 105. The switching block 103 and the conversion block 107 are both rectangular in shape. Two threaded posts 104 are fixed to each of the four outer surfaces of the switching block 103. Dividing posts 105 are threadedly connected to the threaded posts 104. The shaft diameter and shaft spacing of any two dividing posts 105 are different. Dividing holes 1071 corresponding to the dividing posts 105 are provided on each of the four outer surfaces of the conversion block 107, so as to facilitate the replacement of dividing posts 105.

[0025] It also includes a rotating handle 206. The rotating handle 206 is fixed to one side of the rotating block 202 away from the square block 201. The transmission components include a synchronous pulley 207 and a synchronous belt 208. The synchronous pulley 207 is installed on both the rotating block 202 and the shaft of the conversion block 107. The two synchronous pulleys 207 are connected by the synchronous belt 208.

[0026] Therefore, the initial position of the square block 201 is located at the intersection of the cross groove 2022. The upper limiting block 203 then slides into the cross groove 2022, thus the limiting block 203 is in close contact with the outer wall of the square block 201. Meanwhile, the lower limiting block 203, under the influence of gravity, slides into the movable groove 2021. Figure 4 For orientation, the two movable slots 2021 are located at the upper left and lower right respectively, so the rotating handle 206 needs to be rotated clockwise. If the two movable slots 2021 are located at the lower left and upper right respectively, the rotating handle 206 is rotated counterclockwise. When it is necessary to adjust the dividing column 105, the rotating handle 206 is rotated clockwise in multiples of 90 degrees. The rotating handle 206 drives the rotating block 202 to rotate. The rotating block 202 drives the limiting block 203 to rotate. Since the upper limiting block 203 is located in the cross slot 2022, the upper limiting block 203 will abut against the square block 201 during rotation. Therefore, the upper limiting block 203 will drive the square block 201 to rotate together during rotation. The square block 201 drives the rotating rod 106 to rotate. The rotating rod 106 drives the switching block 103 to rotate together. Thus, different dividing columns 105 can be replaced to select the appropriate dividing column 105.

[0027] When the rotating block 202 rotates 90 degrees, the original upper left limit block 203 is rotated to the upper right. Because the counterweight 205 is magnetically connected to the rotating block 202, the original upper left limit block 203 can smoothly rotate to the upper right during this rotation. Therefore, the limit block 203 remains within the cross groove 2022. When the rotating block 202 rotates 180 degrees, the original upper left limit block 203 is rotated to the lower right. The counterweight 205 slides down due to gravity, thereby causing the limit block 203 to slide from the cross groove 2022 into the movable groove 2021. Thus, the limit block 203 is magnetically connected to the rotating block 202. When the rotating block 202 rotates 270 degrees, because the limit block 205 is magnetically connected to the rotating block 202, the original upper left limit block 203 is magnetically connected to the rotating block 202. 2. Magnetic connection allows for smooth rotation to the lower right during this process. At this point, the limiting block 203 remains within the movable groove 2021. When the rotating block 202 rotates 360 degrees, the counterweight 205 slides down due to gravity, thereby causing the limiting block 203 to slide from the movable groove 2021 into the cross groove 2022. The counterweight 205 then reconnects magnetically with the rotating block 202, completing the reset. This ensures that in the vertical direction, the limiting block 203 will not obstruct the square block 201 from operating, while in the horizontal direction, it always ensures that the limiting block 203 is in contact with the square block 201 within the cross groove 2022, thus generating a resisting force during rotation, allowing the square block 201 to rotate.

[0028] When the rotating block 202 rotates, it drives the synchronous pulley 207 to rotate. The synchronous pulley 207 drives another synchronous pulley 207 to rotate via the synchronous belt 208, which in turn causes the conversion block 107 to rotate. This causes the switching block 103 to rotate synchronously with the conversion block 107, thereby ensuring that the dividing column 105 always corresponds to the dividing hole 1071, preventing the operator from forgetting to rotate the conversion block 107 and causing an operational accident.

[0029] Furthermore, a pressure plate 301 is connected to the bottom surface of the slide 102 via a buffer component. The buffer component includes a telescopic tube 302, a piston block 303, a piston rod 304, an elastic element 305, and a sealing ring 306. The slide 102 is rectangular in shape, and piston holes 1021 are provided at the four corners of the slide 102. The piston block 303 is slidably connected to the piston hole 1021 in a sealed manner. The piston rod 304 is fixed to the top surface of the piston block 303. A sealing ring 306 is installed on the top surface of the piston hole 1021. The piston rod 304 passes through the sealing ring 306 in a sealed manner. A space is provided between the sealing ring 306 and the piston block 303. There is an elastic element 305, specifically a spring. The four corners of the slide 102 are connected to the pressure plate 301 through telescopic tubes 302. The bottom surface of the four corners of the slide 102 is provided with connecting holes 1022, which connect the piston hole 1021 and the telescopic tube 302. The telescopic tube 302 is filled with a filler, which is hydraulic oil. There is a certain gap between the piston block 303 and the connecting hole 1022. This can press the artificial skin tightly during cutting to prevent shaking during cutting. At the same time, the buffer component can prevent the artificial skin from being squeezed during cutting, thereby causing damage.

[0030] When the dividing post 105 needs adjustment, the rotating handle 206 is rotated clockwise in multiples of 90 degrees. This rotation causes the rotating block 202 to rotate, which in turn causes the limiting block 203 to rotate. Since the upper limiting block 203 is located within the cross groove 2022, it comes into contact with the square block 201 during rotation. Consequently, the upper limiting block 203 rotates along with the square block 201, which in turn causes the rotating rod 106 to rotate. Rod 106 drives switching block 103 to rotate together, thereby allowing the replacement of different dividing posts 105 to select the appropriate dividing post 105. When rotating block 202 rotates, it drives synchronous pulley 207 to rotate. Synchronous pulley 207 drives another synchronous pulley 207 to rotate via synchronous belt 208, thereby causing conversion block 107 to rotate. This ensures that switching block 103 and conversion block 107 rotate synchronously, thus ensuring that dividing post 105 always corresponds to dividing hole 1071, preventing operators from forgetting to rotate conversion block 107 and causing operational accidents.

[0031] After adjustment, the neonatal artificial skin is placed on the top surface of the conversion block 107. Then, the hydraulic cylinder 108 is activated, and the telescopic rod of the hydraulic cylinder 108 extends, thereby driving the slide block 102 to move downward. The pressure plate 301 then contacts the neonatal artificial skin. As the slide block 102 continues to descend, the telescopic tube 302 is compressed, causing the hydraulic oil inside the telescopic tube 302 to be squeezed from the connecting hole 1022 into the gap between the piston block 303 and the connecting hole 1022. When the dividing column 105 cooperates with the dividing hole 1071 to cut the neonatal artificial skin, the piston block 303 and the connecting hole 1022... The gap between the holes 1022 is filled, and the hydraulic oil squeezes the piston block 303, which in turn squeezes the elastic element 305, causing the elastic element 305 to store elastic potential energy. This causes the hydraulic oil to generate a reaction force, which acts on the pressure plate 301. The pressure plate 301 then fixes the neonatal artificial skin at the moment of cutting to prevent the neonatal artificial skin from shaking during the cutting process, which would result in incomplete cutting. After the cutting is completed, the telescopic rod of the hydraulic cylinder 108 is reset, and the hydraulic oil is reset under the influence of gravity and the elastic element 305, thus completing the drilling operation of the neonatal artificial skin.
