Description

Technical Field

[0001] The present disclosure relates to the field of medical treatment equipment, and more precisely, to an oxygen supply device. Background Art

[0002] In clinical work, for patients with severe respiratory failure that are difficult to correct with conventional respiratory support techniques, extracorporeal life support techniques are usually used as rescue therapies. In existing extracorporeal life support, represented by extracorporeal membrane oxygenation (ECMO), since ECMO operation requires central venous / arterial catheterization, during operation, blood needs to be led to the extracorporeal pipeline and machine, and after being processed by the machine, it is then transfused back into the human body.

[0003] Since blood is used as the oxygen supply medium, various complications related to this process will inevitably occur. Common complications are divided into two categories: (1) body complications, including bleeding at the surgical and intubation sites, embolism, ischemia of the distal limbs, hemolysis, abnormal nervous system function, renal insufficiency, abnormal liver function, and infection, etc.; (2) ECMO mechanical system complications, related to ECMO pipelines and equipment, mainly including poor oxygenation of the oxygenator, plasma leakage, rupture of the circulation pipeline, abnormal functions of the drive pump and heat exchanger, and so on. When these complications are severe, they can affect the patient's life safety and urgent improvement is needed. Utility Model Content

[0017] In one embodiment of the present disclosure, the circulating liquid processing unit includes an exchange component, and the exchange component includes a liquid exchange flow channel and a driving pump; the circulation flow channel and the liquid exchange flow channel are configured to be isolated from each other by a dialysis semi-permeable membrane, and small molecule toxins in the circulating liquid in the circulation flow channel are configured to pass through the dialysis semi-permeable membrane and enter the dialysis liquid in the liquid exchange flow channel, and the driving pump is configured to pump the dialysis liquid that has not undergone small molecule toxin exchange into the liquid exchange flow channel and pump out the dialysis liquid that has completed small molecule toxin exchange from the liquid exchange flow channel.

[0018] The present disclosure provides an oxygen supply device, which can be applied to the life support of patients with impaired respiratory function.

[0037] Unless otherwise specified, the numerical ranges in this document include not only the entire range between its two endpoints, but also several sub-ranges contained therein.

[0038] The present disclosure provides an oxygen supply device, which can be applied to the life-saving rescue of patients with impaired respiratory function. Specifically, the oxygen supply device at least includes a circulation component and a treatment component. The circulation component is configured to transport the oxygen-supplied circulating fluid along a circulation channel to the peritoneal cavity of the biological organism to be oxygen-supplied, and recover the circulating fluid to be treated from the peritoneal cavity of the biological organism to be oxygen-supplied from the circulation channel; the treatment component is configured to supply oxygen to at least the circulating fluid flowing through the oxygen supply device of the circulating fluid to be treated to obtain the oxygen-supplied circulating fluid.

[0039] Thus, during the use of the oxygen supply device of the present disclosure, the treatment component supplies oxygen to the circulating fluid flowing through the oxygen supply device of the circulating fluid to be treated to obtain the oxygen-supplied circulating fluid. The circulation component can transport the oxygen-supplied circulating fluid along the circulation channel to the peritoneal cavity of the biological organism to be oxygen-supplied, and recover the circulating fluid to be treated from the peritoneal cavity of the biological organism to be oxygen-supplied from the circulation channel. Among them, since the peritoneum can act as a semi-permeable membrane, and has a large surface area and rich capillaries, thus, after the oxygen-supplied circulating fluid enters the peritoneal cavity of the biological organism to be oxygen-supplied, the oxygen-supplied circulating fluid can pass through the peritoneum and perform oxygen exchange with the blood in the capillaries in the peritoneum, so as to achieve the purpose of supplying oxygen to the patient in the case of impaired respiratory function of the patient.

[0040] Since the oxygen supply device of the present disclosure can supply oxygen by using the peritoneum of the patient through the circulating fluid, without passing through the human blood circulation system, not only is it unnecessary to perform anticoagulation treatment, effectively avoiding the body complications of the ECMO device, but also since blood treatment devices such as anticoagulation can be omitted, the related mechanical system complications of the ECMO device can also be effectively avoided, improving the operation stability of the oxygen supply device, thereby improving the survival rate and recovery rate of the patient, and reducing the treatment cost of the patient.

[0041] For ease of understanding, the following refers to Figures 1 to 4 and, in conjunction with an embodiment, details the specific structure and working principle of the oxygen supply device of the present disclosure.

[0042] As Figure 1 and Figure 2 shown, the present disclosure provides an oxygen supply device, which can be applied to the life-saving rescue of patients with impaired respiratory function. Specifically, the oxygen supply device at least includes a circulation component and a treatment component. The circulation component is configured to transport the oxygen-supplied circulating fluid along the circulation channel 12 to the peritoneal cavity of the biological organism to be oxygen-supplied, and recover the circulating fluid to be treated from the peritoneal cavity of the biological organism to be oxygen-supplied from the circulation channel 12; the treatment component is configured to supply oxygen to at least the circulating fluid flowing through the oxygen supply device of the circulating fluid to be treated to obtain the oxygen-supplied circulating fluid.

[0043] It is understandable that the circulating fluid can adopt existing formulations such as artificial blood to improve the compatibility with the human body and avoid adverse reactions in patients.

[0044] In this way, during the use of the oxygen supply device of the present disclosure, the processing component supplies oxygen to the circulating fluid flowing through the oxygen supply device in the circulating fluid to be processed, and the oxygen-supplied circulating fluid is obtained. The circulating component can transport the oxygen-supplied circulating fluid along the circulation channel 12 to the peritoneal cavity of the biological organism to be oxygen-supplied, and recover the circulating fluid to be processed from the peritoneal cavity of the biological organism to be oxygen-supplied from the circulation channel 12. Among them, since the peritoneum can serve as a semipermeable membrane, and has a large surface area and rich capillaries, after the oxygen-supplied circulating fluid enters the peritoneal cavity of the biological organism to be oxygen-supplied, the oxygen-supplied circulating fluid can pass through the peritoneum and perform oxygen exchange with the blood in the capillaries in the peritoneum, so as to achieve the purpose of supplying oxygen to the patient in the case where the patient's respiratory function is impaired.

[0045] Since the oxygen supply device of the present disclosure can utilize the peritoneum of the patient for oxygen supply through the circulating fluid, without passing through the human blood circulation system, not only is it unnecessary to perform anticoagulation treatment, effectively avoiding the body complications of the ECMO device, but also since blood treatment devices such as anticoagulation can be omitted, the related mechanical system complications of the ECMO device can also be effectively avoided, improving the operation stability of the oxygen supply device, thereby improving the survival rate and recovery rate of the patient, and reducing the treatment cost of the patient.

[0046] It is understandable that during the use of the oxygen supply device of the present disclosure, a lung ultra-protective ventilation strategy can be adopted to reduce the possibility of spontaneous lung injury, and further improve oxygenation and protect lung function for the patient.

[0047] Specifically, in an embodiment of the present disclosure, as Figure 1 and Figure 2 shown, the circulating component includes a circulating pump 11, a liquid inlet pipe 121 and a liquid outlet pipe 122. The liquid inlet pipe 121 is configured to be connected to a first interface opened on the abdomen of the biological organism to be oxygen-supplied, and the liquid outlet pipe 122 is configured to be connected to a second interface opened on the abdomen of the biological organism to be oxygen-supplied. Both the first interface and the second interface are communicated with the peritoneal cavity of the biological organism to be oxygen-supplied. The circulating pump 11 is configured to transport the oxygen-supplied circulating fluid to the first interface through the liquid outlet pipe 122 and recover the circulating fluid to be processed from the liquid inlet pipe 121.

[0048] Thus, before the use of the oxygen supply device of the present disclosure, a first interface and a second interface are pre-opened on the patient's abdomen, and the liquid inlet pipe 121 is connected to the first interface, and the liquid outlet pipe 122 is connected to the second interface. During the use of the oxygen supply device of the present disclosure, the circulation pump 11 can transport the oxygen-supplied circulating liquid through the liquid outlet pipe 122 to the second interface. Then, after the oxygen-supplied circulating liquid flows into the patient's peritoneal cavity from the second interface along the liquid outlet pipe 122, it can exchange oxygen with the blood in the capillaries in the peritoneum through the peritoneum, so as to achieve the purpose of supplying oxygen to the patient when the patient's respiratory function is impaired. After the oxygen-supplied circulating liquid exchanges oxygen with the blood in the capillaries in the peritoneum, it can flow back into the oxygen supply device along the liquid inlet pipe 121 from the first interface, so as to facilitate the treatment by the oxygen supply device. It can be seen that during the use of the oxygen supply device of the present disclosure, the circulating liquid can be recycled, thereby effectively reducing the treatment cost.

[0049] Specifically, in an embodiment of the present disclosure, the first interface is configured to be higher than the height of the second interface. Since the first interface is higher than the height of the second interface, during the use of the oxygen supply device of the present disclosure, when the oxygen-supplied circulating liquid continuously flows into the patient's peritoneal cavity from the second interface, the liquid level will continuously rise and continuously exchange oxygen with the blood in the capillaries in the peritoneum until it flows to the first interface, then flows out from the first interface and flows back into the oxygen supply device.

[0050] In this way, not only can the residence time of the oxygen-supplied circulating liquid in the patient's peritoneal cavity be prolonged, so as to ensure that the oxygen-supplied circulating liquid can fully exchange oxygen with the blood in the capillaries in the patient's peritoneum, but also the circulating liquid can be naturally recovered by gravity, thereby effectively reducing the energy consumption of the oxygen supply device of the present disclosure.

[0051] Specifically, there are various ways to supply oxygen to the circulating liquid, such as Figure 3 As shown, in an embodiment of the present disclosure, the processing component includes a gas exchange flow channel 211 and a gas driving pump 212; the circulation flow channel 12 and the gas exchange flow channel 211 are configured to be isolated from each other by a gas exchange membrane 213, and the oxygen molecules in the oxygen-rich gas in the gas exchange flow channel 211 are configured to penetrate through the gas exchange membrane 213 into the circulating liquid in the circulation flow channel 12; the gas driving pump 212 is configured to pump the oxygen-rich gas into the gas exchange flow channel 211 and pump out the oxygen-depleted gas after gas exchange from the gas exchange flow channel 211.

[0052] In this way, during the operation of the oxygen supply device of the present disclosure, the gas-driven pump 212 can pump the oxygen-rich gas into the gas exchange flow channel 211. During the flow of the circulating liquid in the circulation flow channel 12, when passing through the corresponding area of the gas exchange membrane 213, the oxygen molecules in the oxygen-rich gas can penetrate through the gas exchange membrane 213 and enter the circulating liquid in the circulation flow channel 12, thereby realizing the oxygen supply to the circulating liquid. Specifically, the oxygen-rich gas can be air or pure oxygen, or a mixed gas of oxygen and other gases.

[0053] Furthermore, in an embodiment of the present disclosure, the carbon dioxide in the circulating liquid in the circulation flow channel 12 is configured to penetrate through the gas exchange membrane 213 and enter the gas in the gas exchange flow channel 211. Since the carbon dioxide in the circulating liquid in the circulation flow channel 12 can penetrate through the gas exchange membrane 213 and enter the gas in the gas exchange flow channel 211, the content of carbon dioxide in the circulating liquid can be effectively reduced, and thus the carbon dioxide in the patient's body can be effectively removed, avoiding the occurrence of respiratory acidosis in the patient.

[0054] As Figure 2 shown, in another embodiment of the present disclosure, the processing component includes a gas bubbling pump 22; the gas bubbling pump 22 is configured to blow the oxygen-rich gas into the circulating liquid in the circulation flow channel 12. After blowing the oxygen-rich gas into the circulating liquid in the circulation flow channel 12, some oxygen molecules will remain in the circulating liquid in the circulation flow channel 12, and some carbon dioxide in the circulating liquid can also be carried out. The whole structure is simple and the cost is low. Moreover, since the gas bubbling pump 22 of the present disclosure blows the oxygen-rich gas into the circulating liquid in the circulation flow channel 12 instead of into the patient's blood, adverse reactions such as hemolysis and air embolism generated by the bubbling oxygenator will not occur, and the safety is extremely high.

[0055] As Figure 2 shown, in an embodiment of the present disclosure, the oxygen supply device of the present disclosure further includes a temperature control unit 23, and the temperature control unit 23 is configured to heat and / or cool the circulating liquid to adjust the temperature of the circulating liquid within a set temperature range. During the operation of the oxygen supply device of the present disclosure, the temperature control unit 23 heats and / or cools the circulating liquid to adjust the temperature of the circulating liquid within a set temperature range, so as to effectively ensure that the patient's body temperature is within a safe range and prevent the patient from having a situation of too low or too high body temperature; especially when the patient has symptoms such as fever, the body temperature of the patient can also be reduced by reducing the temperature of the circulating liquid, or the body temperature of the patient can be reduced by the circulating liquid.

[0056] It is understandable that as a semi-permeable membrane, the peritoneum allows the oxygen-supplied circulating fluid to not only exchange oxygen with the blood in the capillaries within the peritoneum, but also conduct other substance exchanges. Therefore, during the process of flowing through the peritoneal cavity, the oxygen-supplied circulating fluid can carry out small molecule toxins in the blood of the capillaries within the peritoneum. Among them, small molecule toxins refer to substances with a molecular weight < 500D, usually including potassium, phosphorus, magnesium, H+, amino acids, urea, creatinine, uric acid, guanidine, phenols, amines, and other substances. In this way, the oxygen supply device of the present disclosure can not only supply oxygen to the patient, but also remove metabolites and poisons in the patient's body, achieving the purpose of correcting the imbalance of the patient's water and electrolyte and acid-base balance.

[0057] During the continuous circulation of the circulating fluid, a large amount of small molecule toxins will accumulate in the circulating fluid. To ensure that the circulating fluid can continuously absorb small molecule toxins in the patient's body, in an embodiment of the present disclosure, the oxygen supply device of the present disclosure further includes a circulating fluid treatment unit 24, and the circulating fluid treatment unit 24 is configured to remove small molecule toxins from the circulating fluid to be treated.

[0058] In this way, during the continuous circulation of the circulating fluid, the circulating fluid treatment unit 24 can remove small molecule toxins from the circulating fluid to be treated, so as to ensure that the content of small molecule toxins in the circulating fluid is always at a relatively low level, and the circulating fluid can continuously absorb small molecule toxins in the patient's body.

[0059] To remove small molecule toxins from the circulating fluid to be treated, as Figure 2 shown, in an embodiment of the present disclosure, the circulating fluid treatment unit 24 includes an adsorption and filtration component 241, and the adsorption and filtration component 241 is configured to remove small molecule toxins from the circulating fluid to be treated during the process of the circulating fluid to be treated flowing through the adsorption and filtration component 241. In this way, during the process of the circulating fluid to be treated flowing through the adsorption and filtration component 241, small molecule toxins in the circulating fluid to be treated can be removed, enabling the circulating fluid to continuously absorb small molecule toxins in the patient's body.

[0060] And as Figure 4 shown, in an embodiment of the present disclosure, the circulating fluid treatment unit 24 includes an exchange component 242, and the exchange component 242 includes a liquid exchange flow channel 2421 and a driving pump 2422; the circulating flow channel 12 and the liquid exchange flow channel 2421 are configured to be isolated from each other by a dialysis semi-permeable membrane 2423, and small molecule toxins in the circulating fluid in the circulating flow channel 12 are configured to penetrate through the dialysis semi-permeable membrane 2423 into the dialysis fluid in the liquid exchange flow channel 2421, and the driving pump 2422 is configured to pump the dialysis fluid that has not been exchanged into the liquid exchange flow channel 2421 and pump out the dialysis fluid that has completed the exchange from the liquid exchange flow channel 2421.

[0061] In this way, during the operation of the oxygen supply device of the present disclosure, the driving pump 2422 can pump the dialysate that has not undergone small molecule toxin exchange into the liquid exchange channel 2421. During the process of the circulating liquid flowing in the circulation channel 12, when flowing through the corresponding area of the dialysis semipermeable membrane 2423, the small molecule toxins in the circulating liquid can permeate through the dialysis semipermeable membrane 2423 and enter the dialysate in the liquid exchange channel 2421, thereby achieving the purpose of removing small molecule toxins from the dialysate. Moreover, by replacing the dialysate regularly, the circulating liquid will not be contaminated, so that the service life of the circulating liquid can be effectively increased, and the use cost of the oxygen supply device of the present disclosure can be reduced.

[0062] The embodiments of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
