Description

Technical Field

[0001] The invention belongs to the technical field of medical appliances, and in particular relates to a neonatal ice cap for treating hypoxic-ischemic encephalopathy. Background Art

[0002] According to statistics, 2.0‰ to 22.6‰ full-term and near-term newborns suffer from hypoxic-ischemic encephalopathy worldwide, of which 15% to 20% die in the neonatal period, and 20% to 30% of the survivors may have severe neurological sequelae. Mild hypothermia therapy has become one of the most reliable neuroprotective therapies for many brain injury diseases, including hypoxic-ischemic encephalopathy, ischemic stroke, traumatic brain injury, and cardiopulmonary-cerebral resuscitation after cardiac arrest. Mild hypothermia therapy, as an effective auxiliary treatment for neonatal hypoxic-ischemic encephalopathy, can significantly improve the long-term prognosis of children with hypoxic-ischemic encephalopathy. It is currently the most evidence-based treatment method and is widely used in clinical practice. This therapy reduces brain edema and inflammatory response by reducing the brain's metabolic rate and reducing the occurrence and development of brain damage caused by hypoxia. Among them, the head ice cap is a key device for achieving mild hypothermia therapy.

[0003] However, traditional neonatal ice caps have some significant design deficiencies, especially in the management and replacement of the cooling liquid inside the ice cap. Specifically, traditional ice caps mostly adopt a fixed or disposable ice pack design. When the built-in ice pack or freezing medium gradually loses its original cooling effect, its cooling effect weakens and needs to be replaced. However, the design of traditional ice caps often makes this process complicated and time-consuming. Medical staff need to disassemble the ice cap, take out the melted ice pack, refill it with new freezing medium and assemble it again. This process not only increases the workload, but may also cause the ice cap to be damaged due to improper operation, affecting the treatment effect. Due to the inconvenience of the replacement process, traditional ice caps have obvious deficiencies in providing continuous and stable cold therapy effects. The instability of this cooling effect may weaken the efficacy of hypothermia therapy and even have adverse effects on the child; therefore, there are deficiencies and cannot meet the use needs of medical staff. Therefore, further improvement is necessary.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a neonatal ice cap for the treatment of hypoxic-ischemic encephalopathy is provided, in order to achieve a more practical purpose. Summary of the invention

[0069] The specific usage and function of this embodiment are as follows:

[0070] Working principle: When in use, the dust cover 23 on the valve housing 20 is opened, and the external water changing head 30 is inserted into the interior of the valve housing 20. As the water changing head 30 continues to move toward the inside of the valve seat 21, the water changing head 30 is prompted to contact the abutment sleeve 42, and the abutment member 421 is used to support the head of the water changing head 30. At the same time, based on the force applied when the water changing head 30 is pressed, the water changing head 30 pushes the abutment sleeve 42 and the sealing plate 41 to move downward, and the elastic corrugated rubber ring 212 is pulled while the sealing plate 41 moves downward, and as the sealing plate 41 continues to move downward, the sealing block 213 and the water through hole 411 on the sealing plate 41 are separated from each other, so that the sealing plate 41 is opened, thereby forming a water changing channel. ; and in the process of the sealing plate 41 moving downward, the fixed ring 43 is used to drive the linkage rod 441 and the linkage inclined block 442 to move synchronously, so that the linkage inclined block 442 pushes the movable inclined block 53 when moving, so that the movable inclined block 53 drives the water stop plate 51 to wrap around the water change head 30, and uses the water stop strip 511 to fit and contact with the outer wall of the water change head 30, thereby forming a tight physical barrier, further preventing the cooling liquid from overflowing from the tiny gap between the valve seat 21 and the water change head 30 during the replacement process, thereby ensuring the safety and cleanliness of the replacement process, and through this arrangement, not only the risk of cooling liquid leakage is reduced, but also the pollution to the surrounding environment is reduced, thereby ensuring the health and safety of children and medical staff;

[0071] Then, through the control of the external program, the water changing head 30 is driven to inject water into the ice cap. At this time, the cooling liquid flows along the water groove 422 between the abutment parts 421, and then passes through the water port on the sealing plate 41 and the water inlet channel 211 on the valve seat 21 to be injected into the interior of the ice cap body 10, so as to inject the cooling liquid into the ice cap body 10; and when it is necessary to replace the cooling liquid inside the ice cap body 10, the cooling liquid inside the ice cap body 10 can be extracted by the water changing head 30, and the cooling liquid with a constant temperature is injected into the interior of the ice cap body 10 after the cooling liquid with a loss of temperature is extracted. This setting avoids the interruption of cold therapy caused by the inconvenience of replacement of the traditional ice cap due to the loss of the original cooling effect, ensures that the newborn can continue to receive effective head cold therapy during the treatment, is conducive to the relief and recovery of the disease, and the continuous and stable cold therapy environment helps to reduce the discomfort of the newborn and promote the improvement of treatment compliance.

[0072] In addition, after the cooling liquid inside the ice cap body 10 is replaced, the water replacement head 30 needs to be pulled out. As the water replacement head 30 is pulled out, the elastic tension of the elastic corrugated rubber ring 212 pulls the sealing plate 41 to reset, so that the sealing plate 41 and the valve seat 21 fit each other, and the sealing block 213 on the valve seat 21 is reinserted into the water hole 411 on the sealing plate 41, so as to close the sealing plate 41, and then the sealing rubber ring 451 is used to fit and contact with the sealing block 213 to achieve the effect of sealing and stopping water. At the same time, based on the elastic force of the reinforcing spring 64, the reinforcing spring 64 is driven to The rod 63 pushes the reinforcement ring 70 to support and reinforce the sealing plate 41, so that the sealing plate 41 is evenly stressed when closed. In the process of the reinforcement ring 70 reinforcing the sealing plate 41, the reinforcement member 71 simultaneously squeezes the sealing airbag 452 through the opening hole 412, causing the sealing airbag 452 to contact the inner sealing rubber ring 451, so that the sealing rubber ring 451 is in contact with the outer wall of the sealing block 213 to the greatest extent, thereby enhancing its sealing performance and ensuring that the sealing plate 41 can completely isolate the water flow in the closed state, effectively preventing the leakage and backflow of the cooling liquid.
