[0024] Please refer to the accompanying Figures 1 to 5 As shown in the accompanying drawings, the present application provides a leakage-proof structure of a lung transplant donor preservation solution bag, which comprises a bag body 10, the upper end of the bag body 10 is fixed with an inlet and outlet pipe 11, the outer side of the inlet and outlet pipe 11 is fixed with an outer shell 12, the inside of the outer shell 12 is provided with a first cavity 13, the upper end inside the outer shell 12 is fixed with a circular pipe 14, the inside of the circular pipe 14 is provided with a second cavity 15, the inside of the second cavity 15 is slidably connected with a sliding plate 16, the lower end of the sliding plate 16 is fixed with a first sealing rod 17, the lower end of the first sealing rod 17 penetrates through the lower end of the circular pipe 14 and extends into the inside of the inlet and outlet pipe 11, the upper end of the outer side of the outer shell 12 is provided with an external thread, the outer side of the outer shell 12 is provided with a sealing cover 18, the inner wall of the sealing cover 18 is provided with an internal thread, and the external thread and the internal thread are matched, the inside of the sealing cover 18 is fixed with a second sealing rod 19, the lower end of the second sealing rod 19 penetrates through the outer shell 12 and extends into the inside of the second cavity 15.
[0025] In this embodiment, when it is necessary to seal the inlet and outlet pipe 11, the sealing cover 18 with the internal thread is rotated, the internal thread in the inside of the sealing cover 18 is matched with the external thread of the outer shell 12, so that the sealing cover 18 moves downward, at the same time, the second sealing rod 19 fixed in the inside of the sealing cover 18 moves downward, the second sealing rod 19 moves downward to push the sliding plate 16 to slide in the second cavity 15 of the circular pipe 14, and then drives the first sealing rod 17 to insert into the inlet and outlet pipe 11, the first sealing rod 17 and the inlet and outlet pipe 11 form the first sealing, with the sealing cover 18 being further tightened, the second sealing rod 19 can seal the multiple through holes 21 provided on the outer side of the circular pipe 14 when moving downward, the second sealing rod 19 and the first sealing rod 17 jointly constitute a double sealing barrier, which effectively prevents liquid leakage.
[0026] In one preferred embodiment, please refer to Figure 3The inside of the circular tube 14 and outside of the first sealing rod 17 is provided with a spring 20, one end of which is fixedly connected to the circular tube 14 and the sliding plate 16, and a plurality of through holes 21 are formed in the outer side of the circular tube 14 and arranged in a ring shape.
[0027] In this embodiment, in the initial state, the sliding plate 16 is located at the uppermost end in the second cavity 15 under the action of the spring 20, and at this time, the first sealing rod 17 is located at the upper end of the liquid inlet and outlet tube 11, the liquid inlet and outlet tube 11 is in communication with the first cavity 13 in the inside of the shell 12, and the liquid in the bag body 10 can flow into the first cavity 13 through the liquid inlet and outlet tube 11. Since the upper end of the inside of the shell 12 is fixedly connected to the circular tube 14, a plurality of through holes 21 are formed in the outer side of the circular tube 14, and the plurality of through holes 21 are in communication with the first cavity 13, at this time, the liquid in the bag body 10 can flow out through the plurality of through holes 21 of the circular tube 14. Under the action of the spring 20, the sliding plate 16 is located at the uppermost end in the second cavity 15, which can block the liquid from flowing into the second cavity 15.
[0028] Further, please refer to Figure 5 A plurality of anti-skid patterns are formed in the outer side of the sealing cover 18.
[0029] In this embodiment, the anti-skid patterns in the outer side of the sealing cover 18 can effectively prevent slipping by increasing the roughness of the contact surface, so that the tightening or loosening operation is more labor-saving.
[0030] In order to further understand and illustrate, take Figure 1 and Figure 2 for example, a label 25 is arranged on one side of the bag body 10, and an observation port 26 is arranged on the side of the bag body 10 away from the label 25.
[0031] In this embodiment, the label 25 on one side of the bag body 10 is used to record the donor information (such as blood type, age, acquisition time, storage liquid type, etc.), and the observation port 26 is made of transparent material. Without opening the bag body 10, medical staff can directly observe the color and turbidity of the storage liquid to judge whether there is any abnormal situation such as liquid leakage or pollution.
[0032] In a preferred embodiment, please refer to Figure 1 A protective pad 27 is arranged at the lower end of the outer side of the bag body 10, and a handle 28 is fixedly arranged at the upper end of the bag body 10.
[0033] In this embodiment, the protective pad 27 at the lower end of the outer side of the bag body 10 is made of elastic buffer material, which can absorb the impact force by itself deformation when the bag body 10 is placed or falls, reducing the direct collision of the bag body 10 with the hard surface such as the ground or the box, effectively avoiding the damage of the bag body 10, the cracking of the welding seam or the loosening of the interface caused by external pressure, thereby reducing the risk of leakage; and the handle 28 at the upper end facilitates the medical staff to easily carry the bag body 10 by lifting or hanging.
[0034] The working principle of the utility model is:
[0035] In the initial state, the spring 20 pushes the sliding plate 16 to the upper end of the second cavity 15 of the circular tube 14, and the first sealing rod 17 is at the upper end of the liquid inlet and outlet pipe 11, at this time the liquid inlet and outlet pipe 11 is communicated with the first cavity 13 of the shell 12 and the through hole 21 outside the circular tube 14, the liquid can flow normally, and the sliding plate 16 blocks the liquid from entering the second cavity 15. When sealing is required, the sealing cover 18 is rotated, the inner thread of the inner wall is matched with the outer thread at the upper end of the shell 12, the second sealing rod 19 is driven to move downward, the second sealing rod 19 pushes the sliding plate 16 to make the first sealing rod 17 inserted into the liquid inlet and outlet pipe 11 to form the first sealing; with the sealing cover 18 being further tightened, the second sealing rod 19 continues to move downward to block the through hole 21 outside the circular tube 14, and the first sealing rod 17 forms double sealing. The anti-skid pattern outside the sealing cover 18 increases the friction force, and the stable tightening operation is ensured. In addition, the label 25 on one side of the bag body 10 records information, and the observation port 26 on the other side is made of transparent material, so that the state of the preserved liquid can be observed; the protective pad 27 at the lower end of the bag body 10 avoids damage to the bag body 10, and the upper end handle 28 facilitates carrying.
[0036] The above is only the preferred embodiment of the utility model, it should be pointed out that for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model, such as no special description and limitation, are implemented according to the conventional means in the field.
