Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for preventing complications of hyperbaric oxygen therapy in patients with impaired consciousness. Background Technology

[0002] Patients with neurological disorders of consciousness (such as coma, vegetative state, minimally conscious state, etc.) often suffer from impaired neurological function due to brain injury, hypoxic-ischemic encephalopathy, or stroke. Hyperbaric oxygen therapy (HBOT) has become an important adjunctive treatment by increasing blood oxygen concentration and promoting nerve repair.

[0003] Common complications include barotrauma (middle ear, sinuses, lungs), oxygen poisoning (central nervous system type, pulmonary type), decompression sickness, etc. Some patients may experience a worsening of their primary disease (such as pneumothorax) due to uncontrolled contraindications; at the same time, epilepsy cannot be predicted or intervened during the treatment process.

[0004] Designing a device to prevent complications of hyperbaric oxygen therapy for patients with impaired consciousness, reduce complications during hyperbaric oxygen therapy, and provide early warning and intervention for epilepsy has become a technical challenge that urgently needs to be solved by those skilled in the art.

[0033] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] like Figure 1-6 As shown, a device for preventing complications of hyperbaric oxygen therapy in patients with impaired consciousness includes a parietal plate 1 and an occipital plate 3. The parietal plate 1 is connected to the occipital plate 3 through an elastic connecting plate 2. It can adapt to the head contours of different patients and can fix the parietal plate and the occipital plate to the patient's head through the elastic connecting plate.

[0035] The inner arc surfaces of the parietal bone guard plate 1 and the occipital bone guard plate 3 are equipped with elastic electrodes 10 that can fit closely to the patient's head. The elastic electrodes are connected to the electroencephalogram (EEG) signal collector to monitor the patient's brain waves and draw the patient's brain waves into an EEG, which is convenient for medical staff to analyze and diagnose.

[0036] The lower opening edge of the parietal plate 1 is equipped with an ear protection component, which can prevent barotrauma to the patient's middle ear caused by the hyperbaric oxygen chamber.

[0037] An air intake regulating component 8 is installed on the side wall of the ear protection component;

[0038] The air intake regulating assembly is equipped with a drug delivery assembly 7.

[0039] Specifically, the ear protection component includes an earmuff 5 and an elastic sheet 9. The upper end of the earmuff 5 is connected to the elastic sheet 9. When the patient enters the hyperbaric oxygen chamber, the elastic sheet can make the earmuff fit tightly against the patient's ear, protecting the patient's ear and preventing barotrauma to the patient's middle ear during hyperbaric oxygen therapy.

[0040] Specifically, the air intake adjustment assembly 8 includes a nose mask 801, and the upper end of the nose mask 801 is provided with a vent 805.

[0041] A linear motor 802 is installed on the inner surface of the nose mask 801. The fixed end of the linear motor 802 is fixedly installed on the inner surface of the nose mask 801, and the free end of the linear motor 802 is fixedly connected to the baffle 803.

[0042] A guide rail 804 is mounted on the surface of the baffle 803, and the guide rail 804 is slidably connected to the inner surface of the nose mask 801.

[0043] The pressure sensor inside the hyperbaric oxygen chamber sends pressure signals back to the controller in real time, which in turn controls the linear motor to operate, controls the baffle to block the ventilation holes, further controls the air intake inside the nasal mask, and intelligently predicts the risk of oxygen toxicity by analyzing heart rate variability and breathing patterns in real time, combined with treatment pressure and time, and provides early warnings. The baffle also controls the opening of the ventilation holes to prevent patients from suffering from oxygen toxicity.

[0044] Specifically, the drug delivery assembly 7 includes a mounting plate 702 and two fixing brackets 704, which are arranged opposite to each other, with the upper fixing bracket 704 fixedly connected to the lower surface of the mounting plate 702.

[0045] The lower surface of the mounting plate 702 is fixedly connected to the fixed end of the telescopic rod 703, and the free end of the telescopic rod 703 is fixedly connected to another fixing frame 704.

[0046] A spray pipe 701 is mounted on the mounting plate 702;

[0047] The spray tube 701 is threadedly connected to the nasal mask 801, and the spray tube 701 is in communication with the nasal mask 801.

[0048] When the elastic electrode detects epileptiform discharges in the patient's brain waves, such as spikes, sharp waves, 3Hz spike-and-slow-wave complexes, polyspikes, sharp-and-slow-wave complexes, and polyspike-and-slow-wave complexes, it will alert medical staff.

[0049] It also controls the extension and retraction of the telescopic rod to make the fixed frame move relative to each other, squeezing the spray into the patient's nasal cavity to intervene in the patient's epileptic seizures in a timely manner;

[0050] Furthermore, diazepam nasal spray bottles can be clamped between the fixed frames to allow for timely intervention and treatment of patients.

[0051] Specifically, it also includes an elastic cable tie assembly, which includes a first elastic cable tie 4 and a second elastic cable tie 6. One end of the first elastic cable tie 4 is connected to the occipital bone guard plate 3, and the other end of the first elastic cable tie 4 is connected to one side wall of the earmuff 5.

[0052] One end of the second elastic cable tie 6 is connected to the other side wall of the earmuff 5, and the other end of the second elastic cable tie 6 is fixedly connected to the side wall of the nose mask 801.

[0053] It should be noted that the terms “comprising,” “including,” or any other variations thereof used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0054] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
