[0002] Membrane oxygenator, also known as membrane artificial lung, is a device that can perform blood-gas exchange. Among them, blood-gas exchange is mainly carried out through hollow permeable tubes (membrane filaments), that is, the air-oxygen mixed gas of a set ratio flows through the hollow part of the permeable tube, and the human blood of a set flow rate flows through the outer surface of the permeable tube. In this process, the carbon dioxide in the blood will be discharged into the air through the oxygen exchange membrane, and oxygen will enter the blood through the oxygen exchange membrane, realizing the human lung breathing function.

DETAILED DESCRIPTION

[0046] In view of this, the core of the present invention is to provide a membrane oxygenator water vapor condensation prevention device, which can not only be used as a support to fix the membrane oxygenator in clinical applications, but also can continuously prevent the generation of condensed water in the membrane oxygenator, thereby maintaining the membrane oxygenator without condensed water for a long time and improving the gas-blood exchange performance.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Please refer to Figures 1 to 9 .

[0048] Please refer to Figure 1-Figure 3 The membrane oxygenator water vapor condensation prevention device disclosed in the embodiment of the present invention includes a clamping frame 100 and a constant temperature heating mechanism, wherein the clamping frame 100 is used to fix the membrane oxygenator, and the constant temperature heating mechanism is used to emit heat of a preset temperature, and the heat can be transferred 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 working, the constant temperature heating mechanism can be turned on, and the constant temperature heating mechanism emits heat and transfers the heat to the membrane oxygenator, thereby preventing the generation of condensed water in the membrane oxygenator. Compared with the prior art, the membrane oxygenator water vapor condensation device disclosed in the embodiment of the present invention can not only be used as a support to fix the membrane oxygenator in clinical applications, but also can continuously prevent condensed water from being generated in the membrane oxygenator, thereby keeping the membrane oxygenator from generating condensed water for a long time and improving 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 configured to conform to the outer shell of the membrane oxygenator. In this way, the membrane oxygenator can fit 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 body 101 and a shell 102 , wherein the shell 102 is buckled on the clamping frame body 101 , and the constant temperature heating mechanism is arranged between the clamping frame body 101 and the shell 102 .

[0052] The part of the clamping frame body 101 that contacts the air supply pipe of the membrane oxygenator is a heat conducting plate. With this arrangement, the heat generated by the constant temperature heating mechanism can be quickly transferred to the air supply pipe of the membrane oxygenator, thereby preventing the generation of condensed water in the air supply pipe.

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

[0054] In order to ensure that heat can be stably transferred to the membrane oxygenator, the surface of the heat conducting plate disclosed in the embodiment of the present invention that contacts the membrane oxygenator has the same shape as the outer shell of the gas 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 pipe.

[0056] It should be noted that the preset temperature disclosed in the embodiment of the present invention is 38°C-40°C. With such a setting, the effect of preventing the formation of condensed water will not be poor due to too low a temperature, nor will the patient's body temperature be affected due to too high a temperature.

[0057] The embodiment of the present invention does not limit the specific structure of the clamping frame body 101, wherein the clamping frame body 101 can be an integral structure or a split combined structure, and any structure that meets the use requirements of the present invention is within the protection scope of the present invention.

[0058] In order to smoothly take the membrane oxygenator out of the clamping frame body 101, the clamping frame body 101 disclosed in the embodiment of the present invention is preferably a split assembly structure.

[0059] The split assembly structure is composed of at least two clamping plates. As a preferred embodiment, the clamping frame body 101 disclosed in the embodiment of the present invention is composed of 2-4 clamping plates.

[0060] As a more preferred embodiment, please refer to Figure 1, Figure 4-Figure 5 The clamping frame body 101 disclosed in the embodiment of the present invention includes a first clamping block 1011 , a second clamping block 1012 and a third clamping block 1013 .

[0061] Among them, one end of the first clamping block 1011 and one end of the second clamping block 1012 can be rotatably installed on both sides of the third clamping block 1013, and the other end of the first clamping block 1011 and the other end of the second clamping block 1012 can be locked.

[0062] When installing the membrane oxygenator, the first clamping block 1011 can be pushed to move in a direction away from the second clamping block 1012, and / or the second clamping block 1012 can be pushed to move in a direction away from the first clamping block 1011, so that the distance between the first clamping block 1011 and the second clamping block 1012 increases. At this time, it is easy to place the membrane oxygenator in the clamping frame body 101. After the membrane oxygenator and the clamping frame body 101 are matched, the other end of the first clamping block 1011 can be locked with the other end of the second clamping block 1012. In this way, the clamping frame body 101 becomes a stable supporting device, which can effectively support the membrane oxygenator.

[0063] The embodiment of the present invention does not limit the specific structures of the first clamping block 1011, the second clamping block 1012 and the third clamping block 1013. As long as the structures meet the use requirements of the present invention, they are within the protection scope of the present invention.

One end of the first clamping block 1011 is connected to the first connecting portion via a first rotating shaft, and one end of the second clamping block 1012 is connected to the second connecting portion via a second rotating shaft.

[0066] In this way, the first clamping block 1011 can rotate along the first rotation axis, and the second clamping block 1012 can rotate along the second rotation axis. By pushing the first clamping block 1011 and / or the second clamping block 1012, the first clamping block 1011 and / or the second clamping block 1012 expand outward, thereby adjusting the size of the internal installation space of the clamping frame body 101.

[0067] Specifically, the first clamping block 1011 and the second clamping block 1012 each include a vertical clamping portion and a bending portion, wherein the two vertical clamping portions are relatively arranged on both sides of the third clamping block 1013 and are respectively perpendicular to the third clamping block 1013, and the two bending portions are arranged on the same horizontal plane and are respectively parallel to the third clamping block 1013, and the two bending portions can be connected.

[0069] With such arrangement, when the locking member 200 and the locked member 300 are locked, the entire clamping frame body 101 can become a stable support body to support the membrane oxygenator.

[0070] The embodiment of the present invention does not limit the specific structures of the locking member 200 and the locked member 300. As long as the structures meet the use requirements of the present invention, they are within the protection scope of the present invention.

[0073] The rotating lock is connected to the first clamping block 1011 or the second clamping block 1012 via a third rotating shaft, and the pin is fixed on the second clamping block 1012 or the first clamping block 1011 .

[0074] That is to say, when the rotating lock is set on the first clamping block 1011, the pin is fixed on the second clamping block 1012; when the rotating lock is set on the second clamping block 1012, the pin is fixed on the first clamping block 1011, and the locking between the first clamping block 1011 and the second clamping block 1012 is achieved by the cooperation between the rotating lock and the pin.

At this time, the first locking groove 2011 on the first locking rod 201 is clamped with the first pin, and the second locking groove on the second locking rod 202 is clamped with the second pin. In this way, the entire clamping frame body 101 is connected as a whole.
