Description

Technical Field

[0001] The invention relates to the technical field of biomedical oxygen inhalation therapeutic equipment, in particular to a hyperbaric oxygen chamber infant oxygen inhalation device. Background Art

[0002] Hyperbaric Oxygen Therapy (HBO) infant oxygen therapy is a medical intervention that treats various diseases of infants by giving high-concentration oxygen in a pressurized environment, especially playing a vital role in infant hypoxic-ischemic encephalopathy and neonatal intensive care.

[0003] At present, oxygen inhalation for infants in air-pressurized hyperbaric oxygen chambers is mainly done by masks or oxygen tents. Wearing a mask will make the infant feel uncomfortable, and the infant will struggle and refuse to cooperate. The oxygen concentration inhaled does not meet the treatment requirements, and the treatment effect is poor. The same is true for using an oxygen tent. In addition, when the infant struggles, oxygen will leak into the hyperbaric oxygen chamber, causing the oxygen concentration in the chamber to rise and increasing the risk of fire in the chamber. The use of pure oxygen pressurized infant hyperbaric oxygen chambers requires medical institutions to purchase them separately, which is very expensive. During use, since it is a separate enclosed space and there is no family member to accompany the infant, the infant is prone to discomfort. When changing position, such as compressing the respiratory tract or crying, the infant needs to be decompressed and comforted before leaving the chamber for treatment again. Therefore, it is very necessary to find a way to enable family members or medical staff to accompany the infant for treatment and provide a device to care for the infant in real time.

[0004] The prior art "A New Pediatric Hyperbaric Oxygen Chamber" (Publication No.: CN106821655A) allows newborns to be placed in a high-concentration oxygen environment by introducing high-pressure oxygen into the hyperbaric chamber to treat the hypoxia of newborns. However, the prior art still has the following technical problems:

[0005] 1. The oxygen circulation effect in the chamber is poor and the treatment effect is poor. In order to ensure the treatment effect on newborns, the interior of the hyperbaric oxygen chamber must not only ensure the stable circulation of oxygen and carbon dioxide, but also ensure that the pressure in the chamber is maintained within a certain range; the carbon dioxide absorption device of the hyperbaric oxygen chamber in the prior art is arranged on the side wall of the chamber, and the absorption port is also small, while the space in the chamber itself is large, which easily leads to unstable circulation of carbon dioxide and oxygen in the chamber, resulting in a gradual decrease in the oxygen concentration in the chamber and a gradual increase in the carbon dioxide concentration, thereby weakening the oxygen inhalation treatment effect of the newborn, and even seriously threatening the life of the newborn due to insufficient oxygen concentration.

[0006] 2. Smart treatment has poor effects and safety. Due to individual differences among newborns, vital signs data such as heart rate, respiratory rate, blood oxygen saturation and other parameters are all different. The existing technology devices cannot connect to the database of health-related information systems and cloud platforms, and thus cannot optimize the oxygen supply effect for newborns with different vital signs data. This can easily lead to insufficient or excessive oxygen supply, affecting the effect of oxygen therapy. At the same time, it is also impossible to monitor the status of the newborn in real time. During oxygen therapy, it may cause insufficient oxygen supply, resulting in neonatal hypoxia and inability to be treated in time, and the safety of the newborn treatment process is insufficient. Summary of the invention

[0007] The present invention provides a hyperbaric oxygen chamber infant oxygen inhalation device, which can solve the problem that the oxygen and carbon dioxide circulation effect in the hyperbaric oxygen chamber in the prior art is poor, resulting in insufficient oxygen concentration in the chamber, which weakens the treatment effect on newborns and even threatens the life safety of newborns due to poor treatment effect.

[0008] The present application provides the following technical solution: A hyperbaric oxygen chamber infant oxygen inhalation device, comprising a chamber and a chamber cover covering the chamber;

[0009] The inner wall near the bottom of the cabin is provided with an annular exhaust gas collection pipe which is connected to each other from end to end, and a plurality of collection holes are provided on the exhaust gas collection pipe, and a gas separation membrane is provided on the collection holes;

[0010] The cabin is also provided with a gas one-way valve, which can allow outside air to enter the cabin;

[0011] The cabin is also connected with an oxygen inlet pipe, and the oxygen inlet pipe is arranged at a position of the cabin close to the cabin cover.

[0012] Beneficial effects:

[0013] 1. Improve the gas circulation efficiency in the cabin to ensure the effect of oxygen inhalation therapy. Since the molecular weight of carbon dioxide is heavier than that of oxygen, the present invention sets the oxygen inlet pipe near the cabin cover, which is equivalent to the oxygen being above the cabin space when it is introduced into the cabin. The newborn lies face up in the cabin, which can facilitate the newborn to inhale oxygen more quickly, thereby improving the oxygen inhalation efficiency. On the one hand, the exhaled carbon dioxide gas will sink to the bottom of the cabin more easily because its molecular weight is heavier than that of oxygen. On the other hand, the oxygen introduced from the part near the cabin cover will squeeze the carbon dioxide to the bottom of the cabin, further accelerating the sinking speed of carbon dioxide to ensure that the newborn can fully inhale oxygen and improve the treatment effect. At the same time, the carbon dioxide gas that sinks to the bottom will first enter the exhaust gas collection pipe at the bottom of the cabin and then be discharged from the cabin. Compared with the prior art structure of directly setting an exhaust port in the cabin, the exhaust gas collection pipe of the present invention can prevent the oxygen in the cabin from being discharged too quickly along with the carbon dioxide due to the high pressure in the cabin, thereby avoiding waste of oxygen. In addition, the exhaust gas collection pipe is in a ring shape that is connected end to end and is arranged close to the bottom inner wall, covering all four corners of the cabin, avoiding the area that is blocked when the newborn lies down, so that the carbon dioxide above the cabin enters the bottom of the cabin and directly contacts the exhaust gas collection pipe, which can allow the carbon dioxide in the cabin to be quickly discharged, thereby ensuring the circulation exchange efficiency of oxygen and carbon dioxide in the cabin, and further enhancing the oxygen therapy effect of the newborn.

[0014] 2. Ensure sufficient oxygen content to protect the health of the newborn's respiratory system. There are multiple collection holes on the exhaust gas collection pipe, and multiple gas separation membranes are provided on the collection holes. The gas separation membranes can allow carbon dioxide to pass quickly and prevent oxygen from passing, so that the carbon dioxide concentration in the cabin can be quickly reduced and the oxygen concentration in the cabin is more sufficient, ensuring the health of the baby's respiratory system.

[0015] 3. Improve the safety of treatment. Since the cabin is a sealed space, in order to prevent the cabin from having too low pressure, such as the failure of the oxygen delivery system and other unexpected situations, the present invention is provided with a gas one-way valve on the cabin. When the gas pressure in the cabin is lower than the external pressure, the differential pressure will allow the outside air to enter the cabin to replenish the air and prevent the gas in the cabin from flowing into the outside, which can prevent the sudden drop in cabin pressure in an emergency situation, causing life-threatening conditions such as hypoxia of the newborn, thereby effectively improving the safety of treatment.

[0016] 4. Low cost and strong practicality. This device not only enables family members or medical staff to take care of the sick child in real time, but also can deal with the situation in time. The oxygen concentration in the oxygen inhalation device is high and the therapeutic effect is significant. The device of the present invention is simple, low cost and can be reused.

[0017] Furthermore, the cabin is also provided with a waste gas exhaust pipe connected to the waste gas collection pipe, and the waste gas exhaust pipe is arranged on the opposite side of the oxygen inlet pipe, and a one-way valve is provided on the waste gas exhaust pipe.

[0018] Beneficial effect: By connecting the exhaust gas exhaust pipe and setting a one-way valve, the one-way flow of carbon dioxide gas can be further ensured, ensuring that carbon dioxide gas can only be discharged from the cabin and preventing carbon dioxide from flowing back into the cabin, thereby improving the safety and reliability of the device.

[0019] Furthermore, the cabin is also connected to an overpressure exhaust pipe, which is arranged on the same side and above the exhaust gas exhaust pipe. A spring overpressure valve is provided on the overpressure exhaust pipe.

[0020] Beneficial effect: When the pressure in the cabin exceeds the preset value, the spring overpressure valve will automatically open to release the excess pressure in the cabin, ensuring that the pressure in the cabin remains within a certain range, preventing abnormal oxygen delivery and ensuring the safety and reliability of the device.

[0021] Furthermore, a support foot is fixed to the bottom of the cabin, and a universal wheel is rotatably connected to the bottom of the support foot.

[0022] Beneficial effects: The combined design of the support feet and universal wheels can conveniently move the hyperbaric oxygen chamber, improve the operability and safety of the device, and enable medical staff to move the oxygen inhalation device between wards more efficiently and safely.

[0023] Furthermore, a partition is provided in the cabin, and a plurality of holes are opened on the partition. A step is provided on the wall surface inside the cabin, and the partition is mounted on the step. The exhaust gas collection pipe is located below the partition, and the collection holes are evenly distributed on the top of the exhaust gas collection pipe, leaving a gap between the partition and the exhaust gas collection pipe.

[0024] Beneficial effects: The partition forms a supporting platform, and a quilt is laid on the partition so that the newborn can lie on the partition. The holes on the partition make it easy for the carbon dioxide above the partition to sink to the bottom of the partition, and the carbon dioxide at the bottom of the cabin can be squeezed into the gap between the partition and the exhaust gas collection pipe by the oxygen introduced from the top of the cabin. The carbon dioxide is temporarily stored in the gap and then discharged from the collection hole at the top of the exhaust gas collection pipe. This can not only make the carbon dioxide temporarily stored in the gap to avoid carbon dioxide being retained above the partition and affecting the effect of oxygen inhalation therapy, but also make the carbon dioxide enter the gap between the partition and the exhaust gas collection pipe from the top of the cabin, and then directly enter the exhaust gas collection pipe head-on, so as to achieve the purpose of quickly discharging carbon dioxide and improve the circulation efficiency of carbon dioxide in the cabin.

[0025] Furthermore, an anti-static wristband is also provided in the cabin, and a connecting line of the anti-static wristband extends to the outside of the cabin.

[0026] Beneficial effects: The anti-static bracelet can be worn on the wrist of a newborn baby, thereby effectively dissipating static electricity and preventing safety accidents.

[0027] Furthermore, one side of the hatch cover is connected to the mouth of the cabin through a hinge, a handle is fixedly provided on the top of the hatch cover, and the hatch cover is made of transparent plastic material.

[0028] Beneficial effects: The hatch is connected to the cabin with a hinge, which allows the hatch to be opened quickly and effortlessly by pulling the handle, which can improve operating efficiency in emergency situations. The hatch is made of transparent plastic material, which not only makes it easy for medical staff to observe the condition of the newborn in the cabin from the outside, but also prevents static electricity, reduces the harm of static electricity accumulation to newborns, and improves the safety of equipment use.

[0029] Furthermore, the mouth of the cabin is also provided with a rubber sealing strip.

[0030] Beneficial effect: After the hatch cover covers the cabin opening, the rubber sealing strip can fill the contact gap between the cabin and the hatch cover, thereby improving the sealing inside the cabin, ensuring that the cabin is in a closed environment, preventing pressure and gas leakage in the cabin, and improving the safety of the device and the effectiveness of oxygen therapy. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 It is the structural front view of the present invention.

[0032] Figure 2 It is a left view of the present invention. DETAILED DESCRIPTION

[0033] The following is further described in detail through specific implementation methods:

[0034] The marks in the drawings of the specification include: hatch cover 1, gas non-return valve 2, oxygen inlet pipe 3, partition 4, cabin 5, support leg 6, universal wheel 7, exhaust gas collection pipe 8, exhaust gas exhaust pipe 9, spring overpressure valve 10, overpressure exhaust pipe 11, handle 12.

[0035] Embodiment 1

[0036] like Figure 1 and Figure 2 As shown, the hyperbaric oxygen chamber infant oxygen inhalation device comprises a chamber 5, a chamber cover 1 covering the chamber 5, a support leg 6 fixed to the bottom of the chamber 5, and a universal wheel 7 installed at the bottom of the support leg 6.

[0037] An annular exhaust gas collection pipe 8 is provided near the bottom inner wall of the cabin 5, which is connected to each other end to end. The annular shape referred to in this embodiment includes circular, square, and special-shaped pipes. As long as the pipes are connected end to end, they fall within the protection scope of this technology. The exhaust gas collection pipe 8 is arranged in a ring shape at the corners of the cabin 5, which can more comprehensively discharge the carbon dioxide in the cabin 5 quickly, thereby ensuring the circulation exchange efficiency of oxygen and carbon dioxide in the cabin 5; a plurality of collection holes are evenly distributed above the exhaust gas collection pipe 8, and the collection holes are located at the top of the exhaust gas collection pipe 8, and gas is provided on the collection holes. Separation membrane, the gas separation membrane is a carbon dioxide selective permeable membrane, the material of which is polyimide (PI). The gas separation membrane can allow carbon dioxide to pass quickly and prevent oxygen from passing through; the cabin 5 is also connected to an exhaust gas exhaust pipe 9, and one side of the exhaust gas collection pipe 8 is connected to an exhaust gas discharge pipe, which extends out of the cabin 5 and is connected to the exhaust gas discharge system, and a one-way valve is provided on the exhaust gas exhaust pipe 9, which can make the carbon dioxide flowing out of the exhaust gas exhaust pipe 9 only be discharged from the cabin 5, preventing carbon dioxide from flowing back into the cabin 5, so as to improve the safety of the device.

[0038] A partition 4 is also provided in the cabin 5. The partition 4 is located above the exhaust gas collection pipe 8. A step is provided on the wall inside the cabin 5, so that the partition 4 can be erected on the step. The partition 4 is used to form a supporting platform. A quilt can be laid on the partition 4 so that the newborn can lie on the partition 4; a plurality of holes are evenly distributed on the partition 4, and the holes can be only located in the circumference of the partition 4, or can be evenly distributed on the plate surface. The latter is preferred in this embodiment. The holes are arranged in this way to facilitate the carbon dioxide above the partition 4 to sink to the bottom of the partition 4. A gap is left between the partition 4 and the exhaust gas collection pipe 8, and the gap can accommodate the carbon dioxide that sinks to the bottom of the cabin 5, so that the carbon dioxide is temporarily stored in the gap, thereby avoiding the carbon dioxide from being retained above the partition 4 and affecting the oxygen therapy effect.

[0039] A gas one-way valve 2 is provided on the side wall of the cabin 5, and the gas one-way valve 2 can allow outside air to enter the cabin 5; when the gas pressure in the cabin 5 is lower than the pressure outside the cabin 5, the influence of the differential pressure will allow outside air to enter the cabin 5 to replenish the air and prevent the gas in the cabin 5 from flowing into the outside, which can prevent the air pressure in the cabin 5 from suddenly dropping in an emergency situation, causing life-threatening conditions such as neonatal hypoxia, thereby effectively improving the safety of treatment.

[0040] like Figure 1As shown, one side of the cabin 5 is connected to an oxygen inlet pipe 3, which is arranged at a position of the cabin 5 close to the hatch 1 and located on the opposite side of the exhaust gas exhaust pipe. The oxygen inlet pipe 3 is used to connect with the oxygen supply system. When oxygen is introduced into the cabin 5, the oxygen is above the space of the cabin 5 and is located above the head of the newborn, which can facilitate the newborn to inhale oxygen more quickly, thereby improving the oxygen absorption efficiency; and the exhaled carbon dioxide gas will, on the one hand, be more likely to automatically sink to the bottom of the cabin 5 because its molecular weight is heavier than that of oxygen. On the other hand, the oxygen introduced from the position close to the hatch 1 will also squeeze the carbon dioxide to the bottom of the cabin 5, thereby accelerating the sinking speed of the carbon dioxide to ensure that the newborn can fully inhale oxygen and improve the treatment effect.

[0041] The other side of the cabin 5 is also connected to an overpressure exhaust pipe 11, which is arranged on the same side and above the exhaust gas exhaust pipe 9, and a spring overpressure valve 10 is arranged on the overpressure exhaust pipe 11. A pressure sensor is arranged in the cabin 5, and the entire device is also provided with a PLC controller, which is electrically connected to the pressure sensor in the cabin 5 and the control valve of the oxygen delivery system. The oxygen delivery pressure in the cabin 5 is controlled by the PLC controller to ensure that the pressure in the cabin 5 is kept within a certain range. At the same time, if the oxygen delivery pressure of the device is too high, the spring overpressure valve 10 will automatically open to release the excess pressure in the cabin 5 to ensure the safety and reliability of the device.

[0042] An anti-static wristband is also fixed on the inner wall of the cabin 5, and the connecting line of the anti-static wristband is passed through the outside of the cabin 5. The anti-static wristband can be worn on the wrist of the newborn, thereby effectively dissipating static electricity and preventing safety accidents.

[0043] like Figure 2 As shown, one side of the hatch cover 1 is connected to the mouth of the cabin 5 by a hinge, and a handle 12 is fixedly provided on the top of the hatch cover 1. The hatch cover 1 can be opened or closed quickly and labor-savingly by pulling the handle 12. A circle of rubber sealing strip is provided at the mouth of the cabin 5. After the hatch cover 1 covers the mouth of the cabin 5, the rubber sealing strip can fill the contact gap between the cabin 5 and the hatch cover 1, thereby improving the sealing inside the cabin 5 and ensuring that the cabin 5 is in a closed environment; the hatch cover 1 is made of transparent plastic material, which can facilitate medical staff to observe the condition of the newborn in the cabin 5 from the outside, and can also prevent static electricity, reduce the harm of static electricity accumulation to the newborn, and improve the safety of equipment use.

[0044] The method of using this device is as follows:

[0045] The hatch 1 is lifted and opened, and the newborn is placed above the partition 4 so that the head of the newborn is located on one side of the oxygen inlet pipe 3. The hatch 1 is then closed, and oxygen is introduced into the cabin 5 to perform oxygen inhalation therapy on the newborn.

[0046] When the pressure in the cabin 5 changes, such as when the pressure sensor in the cabin 5 detects that the pressure exceeds the preset value, a signal will be transmitted to the PLC controller. On the one hand, the PLC controller controls the control valve of the oxygen supply system to reduce the opening, and on the other hand, the valve of the spring overpressure valve 10 is opened to release the excess pressure in the cabin 5 until the pressure drops to the preset value and the spring overpressure valve 10 is closed; if the pressure in the cabin 5 is too low, the PLC controller controls the control valve of the oxygen supply system to increase the opening, increase the oxygen supply pressure to adjust the pressure in the cabin 5 to the preset value. At the same time, if an abnormality occurs in the equipment and the internal pressure of the cabin 5 is lower than the external atmospheric pressure, due to the differential pressure, the air outside the cabin 5 will also be replenished into the cabin 5 through the gas one-way valve 2 to prevent the sudden drop in the air pressure in the cabin 5 in an emergency situation, causing life-threatening neonatal hypoxia, so as to ensure the safety of treatment.

[0047] Embodiment 2

[0048] The difference between this embodiment and the first embodiment is that a communication module and an alarm module are further provided in the present device. The communication module can connect the PLC controller to the cloud server, so that the vital sign data of the infant, such as blood oxygen saturation, heart rate, respiratory rate and other physiological parameters, can be uploaded to the sharing platform such as medical and health big data or health-related information systems and cloud platforms, forming an intelligent diagnosis and treatment ecosystem that combines online and offline, and relying on artificial intelligence and machine learning technology, comprehensively analyzes and processes a variety of case big data, generates trend reports and prediction models, so as to provide the optimal oxygen supply for newborns with different vital sign data in a targeted manner, so as to achieve the optimal regulation of oxygen supply; at the same time, the alarm module can also issue an alarm in time when the vital sign data of the newborn is abnormal, so that medical staff or parents can take quick action to improve the safety of diagnosis and treatment of newborns.

[0049] The above are only embodiments of the present invention. The invention is not limited to the fields involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
