Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a membrane oxygenator anti-vapor condensation device. Background Art

[0002] A membrane oxygenator, also known as a membrane artificial lung, is a device that performs blood-gas exchange. This exchange occurs primarily through a hollow permeable tube (membrane filament). A mixture of air and oxygen at a set ratio flows through the hollow portion of the tube, while blood at a set flow rate flows through the outer surface. During this process, carbon dioxide in the blood is expelled into the air through the oxygen exchange membrane, while oxygen enters the blood through the membrane, enabling the human lung to function properly.

[0003] Oxygenators used clinically generally have the serious problem of decreased blood oxygen exchange performance during use. According to the instructions, the air supply channel needs to be purged with a large flow of condensed water once a day. However, large-flow condensed water purging can bring clinical risks such as decreased blood oxygen and hypocapnia to patients, causing physical discomfort to patients. Improper operation can also pose a life-threatening risk.

[0004] Currently, there are some devices at home and abroad that prevent the formation of condensed water in membrane oxygenators, but they cannot continuously prevent the formation of condensed water in membrane oxygenators.

Detailed implementation mode

[0046] In view of this, the core of the present invention is to provide a moisture condensation prevention device for a membrane oxygenator, which can not only support and fix the membrane oxygenator in clinical applications, but also continuously prevent the generation of condensed water in the membrane oxygenator, so as to keep the membrane oxygenator free of condensed water for a long time and improve the gas-blood exchange performance.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Please refer to Figures 1 to 9 .

[0048] Please refer to Figures 1 - 3 , the moisture condensation prevention device for a membrane oxygenator disclosed in the embodiments of the present invention includes a clamping frame 100 and a constant temperature heating mechanism. Among them, the clamping frame 100 is used to fix the membrane oxygenator, and the constant temperature heating mechanism is used to emit heat at a preset temperature, and the heat can be transmitted to the membrane oxygenator through the clamping frame 100 to prevent the generation of condensed water in the membrane oxygenator.

[0049] When the membrane oxygenator starts to work, the constant temperature heating mechanism can be turned on. The constant temperature heating mechanism emits heat and transmits the heat to the membrane oxygenator, thereby preventing the generation of condensed water in the membrane oxygenator. Compared with the prior art, the moisture condensation prevention device for a membrane oxygenator disclosed in the embodiments of the present invention can not only support and fix the membrane oxygenator in clinical applications, but also continuously prevent condensed water for the membrane oxygenator, so as to keep the membrane oxygenator free of condensed water for a long time and improve the gas-blood exchange performance.

[0050] In order to ensure stable heat transfer and prevent cold air from entering the gap between the membrane oxygenator and the clamping frame 100, the contact surface of the clamping frame 100 disclosed in the embodiment of the present invention for contacting the membrane oxygenator is shaped to conform to the outer shell of the membrane oxygenator. With this setting, the membrane oxygenator can fit closely with the clamping frame 100, so that the heat generated by the constant temperature heating mechanism can be fully transferred.

[0051] As a further embodiment, the clamping frame 100 disclosed in the embodiment of the present invention includes a clamping frame main body 101 and a housing 102. Among them, the housing 102 is buckled on the clamping frame main body 101, and the constant temperature heating mechanism is arranged between the clamping frame main body 101 and the housing 102.

[0052] Among them, the part of the clamping frame main body 101 for contacting the air supply pipeline of the membrane oxygenator is a heat conducting plate. With this setting, the heat generated by the constant temperature heating mechanism can be quickly transferred to the air supply pipeline of the membrane oxygenator, thereby preventing the generation of condensed water in the air supply pipeline.

[0053] Moreover, the heat generated by the constant temperature heating mechanism can also be conducted to other positions outside the air supply pipeline of the membrane oxygenator.

[0054] In order to enable the heat to be stably transferred to the membrane oxygenator, the surface of the heat conducting plate contacting the membrane oxygenator in the embodiment of the present invention has the same shape as the outer shell of the air supply pipeline.

[0055] As a further embodiment, the width of the heat conducting plate disclosed in the embodiment of the present invention is equal to the width of the air supply pipeline.

[0056] It should be noted that the preset temperature disclosed in the embodiment of the present invention is 38°C - 40°C. With this setting, it will neither result in poor prevention of condensed water generation due to too low temperature, nor affect the patient's body temperature due to too high temperature.

[0057] The embodiment of the present invention does not limit the specific structure of the clamping frame main body 101. Among them, the clamping frame main body 101 can be an integral structure or a split combination structure. As long as the structure meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0058] In order to facilitate the smooth removal and placement of the membrane oxygenator from the clamping frame main body 101, the clamping frame main body 101 disclosed in the embodiment of the present invention is preferably a split combination structure.

[0059] Among them, the split combination structure is at least composed of two or more clamping plates. As a preferred embodiment, the clamping frame main body 101 disclosed in the embodiment of the present invention is composed of 2 - 4 clamping plates.

At this time, it is easy to place the membrane oxygenator inside the clamping frame body 101. After the membrane oxygenator is fitted with the clamping frame body 101, the other end of the first clamping block 1011 and the other end of the second clamping block 1012 can be locked. In this way, the clamping frame body 101 becomes a stable supporting device, and effective support for the membrane oxygenator can be achieved.
