Description

Technical Field

[0001] The present invention relates to the field of cardiovascular medical devices, and particularly to a pediatric cardiovascular respirator. Background Art

[0002] Cardiovascular respirators used in pediatrics are usually medical devices specifically designed for children, aiming to support children suffering from dyspnea or heart diseases. These respirators sometimes incorporate cardiac support functions to help children with heart diseases or heart failure maintain normal oxygen supply.

[0003] When using cardiovascular respirators in pediatrics, some unique challenges and requirements are usually faced because the physiological characteristics of children are different from those of adults. Specifically, the following problems need to be solved by pediatric cardiovascular respirators: 1. Children often have a resistant attitude towards medical devices, especially respirator devices. The respirator needs to consider the comfort of children, and the design should avoid causing excessive discomfort and reducing the psychological impact on children. 2. The airways of children are much smaller and more flexible than those of adults, and are prone to obstruction and compression. The oxygen demand of children is usually different from that of adults. Therefore, the device needs to be able to accurately adjust the oxygen concentration to avoid excess or deficiency; In view of the above problems, we propose a pediatric cardiovascular respirator.

An oxygen replenishment port 103 is arranged on the side of the oxygen cylinder 101 opposite to the control switch 102. An electric telescopic rod 104 is arranged at the bottom end inside the oxygen cylinder 101. The electric telescopic rod 104 is connected to an oxygen storage bladder 106 through a connecting plate 105 above it.

[0016] Further, the gas transmission component includes a main gas transmission pipe 201. An oxygen mask 202 is connected above the main gas transmission pipe 201. Lower connecting buckles 203 are symmetrically arranged on both sides of the oxygen mask 202. Lower bandages 204 are sleeved inside the lower connecting buckles 203. An intermediate connecting block 205 is connected directly above the oxygen mask 202. A head fixing plate 206 is connected above the intermediate connecting block 205. Upper connecting buckles 207 are connected to both ends of the head fixing plate 206. Upper bandages 208 are sleeved inside the upper connecting buckles 207. The bottom end of the main gas transmission pipe 201 is connected to an adjustment component.

[0017] Further, the adjustment component includes a knob 301 connected below the main gas transmission pipe 201. The knob 301 is rotatably connected to the oxygen cylinder 101. The middle of the knob 301 is hollowed out. Three first through holes 302 are evenly distributed around the bottom end circumference of the knob 301. A connecting column 303 is arranged below the knob 301. The connecting column 303 is fixed on the inner wall of the oxygen cylinder 101. A circular groove 304 is provided at the middle position of the connecting column 303. Three second through holes 305 are evenly distributed around the inner circumference of the circular groove 304.

[0018] Further, the airbag inflation component includes a first gear 401 connected to the periphery of the knob 301. A second gear 402 meshing with the first gear 401 is arranged on the side of the first gear 401. A connecting shaft 403 coaxial with the second gear 402 is connected to the side of the second gear 402. The connecting shaft 403 is rotatably connected to the inner wall of the oxygen cylinder 101. A fixing plate 404 rotatably connected to the connecting shaft 403 is arranged on the periphery of the connecting shaft 403. A limiting plate 405 is connected to the side of the fixing plate 404. The limiting plate 405 is fixed on the inner wall of the oxygen cylinder 101. A movable plate 406 in screw fit with the connecting shaft 403 is arranged on the periphery of the connecting shaft 403. A first airbag 407 is connected to one side of the movable plate 406. One end of the first airbag 407 opposite to the movable plate 406 is connected to a side air pipe 408. The side air pipe 408 is connected to a second airbag 409 arranged on the back of the oxygen mask 202.

[0019] The working principle of the present invention is specifically described as follows: In this design, when the pediatric cardiology respirator works, first, medical staff place the head fixing plate 206 on the forehead of the child patient. Subsequently, the lower bandage 204 and the upper bandage 208 are stretched to fix the oxygen mask 202 on the face of the child patient. Subsequently, the control switch 102 on the side of the oxygen cylinder 101 is pressed, and the electric telescopic rod 104 arranged inside the oxygen cylinder 101 is started through the switch 102. After being started, the electric telescopic rod 104 moves upward slowly and uniformly. After the electric telescopic rod 104 moves upward, it drives the connecting plate 105 above it to move upward. After the connecting plate 105 moves upward, it squeezes the oxygen storage bag 106, squeezing the oxygen inside the oxygen storage bag 106 upward. The squeezed oxygen first passes through the second through-hole 305 in the middle of the connecting column 303, then passes upward through the first through-hole 302 in the middle of the knob 301, continues to pass upward through the main air supply pipe 201, and finally is delivered into the oxygen mask 202 above to achieve oxygen supply. When the respirator works, the oxygen concentration can be adjusted by turning the knob 301. First, turn the knob 301 so that the pointer mark above it aligns with the scale set above the oxygen cylinder 101. After the knob 301 rotates, it drives the first through-hole 302 at its bottom end to rotate. After the first through-hole 302 rotates, it cooperates with the second through-hole 305 below it to achieve the control of the oxygen flow rate. When the knob 301 rotates, it drives the first gear 401 on its periphery to rotate. After the first gear 401 rotates, it drives the second gear 402 meshing with it to rotate. After the second gear 402 rotates, it drives the connecting shaft 403 coaxial with it to rotate. After the connecting shaft 403 rotates, it drives the movable plate 406 that is helically engaged with it to move. After the movable plate 406 moves, it squeezes the first airbag 407 connected to it. After the first airbag 407 is squeezed, the gas inside it flows through the side air pipe 408 to the second airbag 409 above. The inflated second airbag 409 can reduce the squeezing feeling of the oxygen mask 202 on the face of the child patient, increase comfort, reduce the impact on the child's psychology, and thus reduce the resistance of the child to the medical device.
