[0030] The membrane layer expansion structure includes a lower base 100, an upper pressing seat 200 and a longitudinally arranged plug plate 300, the upper pressing seat 200 and the lower base 100 are arranged in an upper and lower interval, and there is a placement interval between the upper pressing seat 200 and the lower base 100 for placing the medical tube membrane 400; the medical tube membrane 400 includes an upper membrane layer and a lower membrane layer, the upper membrane layer and the lower membrane layer are integrally formed and arranged in a surrounding shape; the upper membrane layer and the lower membrane layer are bonded to each other up and down, and a bonding seam is formed between the upper membrane layer and the lower membrane layer;

[0031] The medical tube film 400 is placed in the placement interval, the lower film layer abuts on the lower base 100, and the upper pressing seat 200 presses downward on the upper film layer; the upper pressing seat 200 has an upper moving block 500 that can move up and down elastically, and the upper moving block 500 abuts downward on the upper film layer; the lower base 100 has a lower moving block 600 that can move up and down elastically, and the lower moving block 600 abuts upward on the lower film layer;

[0032] The plug plate 300 is arranged opposite to the fitting seam, and the plug plate 300 has an insertion end facing the fitting seam, and the insertion end is pointed. The plug plate 300 moves toward the fitting seam, and the insertion end is inserted into the fitting seam. The upper moving block 500 moves upward under the pressure of the plug plate 300, and the lower moving block 600 moves downward under the pressure of the plug plate 300. The plug plate 300 separates the upper film layer from the lower film layer, and the upper film layer and the lower film layer are enclosed to form an open mold cavity.

[0033] The film layer opening structure provided above clamps and limits the medical tube film 400 through the upper pressing seat 200 and the lower base 100, and then inserts the plug plate 300 into the fitting seam between the medical tube film 400. The mobility of the upper moving block 500 and the lower moving block 600 is utilized so that the plug plate 300 will not cause damage to the medical tube film 400 during the insertion of the fitting seam. The structure is simple and easy to operate; the problem of complicated steps and troublesome operation in the process of opening the medical tube film 400 is solved.

[0034] The upper pressure seat 200 has an upper sliding cavity 201 which is arranged longitudinally and for the upper moving block 500 to move up and down. The bottom of the upper sliding cavity 201 has a bottom opening. The upper moving block 500 is movably placed in the upper sliding cavity 201. When the upper moving block 500 is pressed upward by the plug plate 300, the upper moving block 500 moves upward along the upper sliding cavity 201. When the plug plate 300 is separated from the upward pressure on the upper moving block 500, the upper moving block 500 moves downward along the upper sliding cavity 201 to reset.

[0035] In this embodiment, the upper moving block 500 is mainly used to protect the upper film layer when the inserting plate 300 opens the medical tube film 400 and does not cause any obstruction to the opening of the inserting plate 300 .

[0036] The bottom of the upper moving block 500 has an abutting surface that abuts against the upper film layer. When the upper moving block 500 is not pressed upward by the plug plate 300, the abutting surface is flush with the bottom opening of the upper sliding cavity 201. In this way, the abutting surface of the upper moving block 500 is flush with the bottom opening of the upper sliding cavity 201, which can have a pressing effect on the upper film layer, so that the opening of the medical tube film 400 can be squeezed and protected by the upper moving block 500, so as to avoid the uneven joint seam of the medical tube film 400 and damage when the plug plate 300 is inserted into the medical tube film 400.

[0037] The bottom of the upper pressing seat 200 has a bottom side surface that abuts against the upper film layer, and the bottom side surfaces are respectively arranged on both sides of the bottom opening of the sliding cavity, and when the upper moving block 500 is not pressed upward by the plug plate 300, the abutting surface is flush with the bottom side surface. In this way, the upper pressing seat 200 and the upper moving block 500 can evenly press and protect the medical tube film 400.

[0038] An upper spring 202 is provided in the upper sliding cavity 201 to drive the upper moving block 500 to move downward and reset. The lower end of the upper spring 202 is connected to the top of the upper moving block 500 , and the upper end of the upper spring 202 is connected to the top of the upper sliding cavity 201 .

[0039] In this embodiment, the upper spring 202 is used to increase the elastic pressure on the upper moving block 500, so that the upper moving block 500 can move downward along the upper sliding cavity 201 to reset when not subjected to upward pressure; it can also increase the extrusion protection of the upper moving block 500 on the upper membrane layer.

[0040] The top of the upper moving block 500 is connected to a guide rod 203 that moves up and down with the upper moving block 500, and the top of the guide rod 203 movably passes through the upper pressure seat 200. In this way, the guide rod 203 is used to increase the weight pressure on the upper moving block 500, so that the upper moving block 500 can move downward along the upper sliding cavity 201 to reset when it is not pressed upward; it can also increase the extrusion protection of the upper moving block 500 on the upper film layer, and further limit the moving direction of the upper moving block 500 in the upper sliding cavity 201.

[0041] The lower base 100 has a placement surface facing upward and for placing the lower film layer, and the placement surface is flat.

[0042] In this way, the lower film layer can be placed flatly, and will not be damaged by the insertion of the insert plate 300 when the medical tube film 400 is opened due to the uneven placement of the medical tube film 400.

[0043] A lower descending cavity 101 is longitudinally arranged in the lower base 100 and is used for elastically moving the upper moving block 500 up and down; the top of the lower descending cavity 101 has a top opening; the lower moving block 600 is movably placed in the lower descending cavity 101, and the lower descending cavity 101 is provided with a lower spring 102 for driving the lower moving block 600 to move upward and reset; when the lower moving block 600 is pressed downward by the plug plate 300, the lower moving block 600 moves downward along the lower descending cavity 101, and when the plug plate 300 is separated from the downward pressure on the lower moving block 600, the lower spring 102 drives the lower moving block 600 to move upward and reset along the lower descending cavity 101.

[0044] In this embodiment, the lower moving block 600 is mainly used to protect the lower film layer when the inserting plate 300 opens the medical tube film 400 and does not cause any obstruction to the opening of the inserting plate 300 .

[0045] The lower spring 102 is longitudinally arranged in the lower sliding cavity 101 , the upper end of the lower spring 102 is connected to the bottom of the lower moving block 600 , and the lower end of the lower spring 102 passes through the bottom of the lower sliding cavity 101 .

[0046] In this embodiment, the lower spring 102 is used to increase the elastic pressure on the lower moving block 600, so that the lower moving block 600 can move upward along the lower sliding cavity 101 to reset when not subjected to upward pressure; it can also increase the extrusion protection of the lower membrane layer by the lower moving block 600.

[0047] The lower moving block 600 is arranged in a convex structure, and the top of the lower moving block 600 is flush with the top of the lower base 100; the lower sliding cavity 101 corresponds to the shape of the lower moving block 600, and the lower moving block 600 is arranged opposite to the upper moving block 500.

[0048] In this embodiment, the lower moving block 600 corresponds to the shape of the lower lower cavity 101 to prevent the lower moving block 600 from being ejected from the lower base 100 by the lower spring 102. By arranging the lower moving block 600 relative to the upper moving block 500, the accuracy of the opening of the medical tube membrane 400 by the insert plate 300 can be improved.

[0049] The bottom of the plug board 300 has a bottom surface, which is arranged horizontally, and the front end of the bottom surface intersects at the insertion end; the top of the plug board 300 has a top surface, which is arranged inclined downward along the direction of insertion of the plug board 300 toward the fitting seam, and the front end of the top surface intersects at the insertion end.

[0050] In this way, the lower film layer can be protected from being damaged by insertion, and the insertion accuracy of the inserting plate 300 into the opening of the medical tube film 400 can be improved.

[0051] The plug board 300 is provided with a cavity 301 with openings on both sides, and the openings on both sides of the cavity 301 are provided with expansion strips 302 that swing outwards, and the end of the expansion strip 302 that is away from the insertion end is inserted through the cavity 301 through a positioning pin, and the end of the expansion strip 302 that is facing the insertion end is movably attached to the cavity 301, and adjacent expansion strips 302 are arranged opposite to each other and connected by an elastic strip 303; a slide groove for reciprocating sliding of a push strip 304 is provided on the top of the plug board 300, and the slide groove is connected to the cavity 301; the push strip 304 is located between adjacent expansion strips 302, and the top of the push strip 304 is exposed at the top of the plug board 300, and the bottom of the push strip 304 is inserted into the cavity 301;

[0052] When the plug plate 300 moves toward the fitting seam, the insertion end is inserted into the fitting seam, the upper moving block 500 is pressed by the plug plate 300 and moves upward, and the lower moving block 600 is pressed by the plug plate 300 and moves downward, and the upper moving block 500 resists the push bar 304 from moving forward, and the push bar 304 passively pushes the expansion bar 302 to swing toward the two sides of the cavity 301, and the fitting seam expansion position is further expanded to the set caliber, and the upper film layer and the lower film layer are enclosed to form an open mold cavity;

[0053] When the inserting plate 300 is separated from the medical tube film 400 , the elastic strip 303 drives the expansion strip 302 to move into the cavity 301 to reset, and the expansion strip 302 presses the push strip 304 to reset.

[0054] In this embodiment, the opening size of the medical tube film 400 is further set by the expansion strip 302 built into the plug plate 300. This design is conducive to the protection of the medical tube film 400 when opening. The smaller the size of the plug plate 300, the higher the accuracy of the plug plate 300 inserted into the fitting seam of the medical tube film 400. By limiting the size of the push strip 304, the expansion distance of the expansion strip 302 can be controlled, thereby controlling the size of the opening of the medical tube film 400. The structure is simple and can be reused.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
