[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Specific examples are given below.

[0029] See also Figure 1-Figure 5The utility model provides a dialyzer leakage prevention device, comprising a dialyzer body 1; a pair of guide rails 11 are fixedly connected to the inner side wall of the dialyzer body 1; the guide rails 11 are symmetrically arranged on both sides of the dialyzer body 1 and have the same structure; a slider 12 is slidably connected to the inner side wall of the guide rail 11; a first spring 13 is fixedly connected between the slider 12 and the guide rail 11; a sealing gasket 14 is fixedly connected to the side wall of the slider 12; a first magnetic strip 15 is fixedly connected to the side wall of the sealing gasket 14; a pair of through holes 16 are opened on the side wall of the dialyzer body 1; the through holes 16 are symmetrically arranged on the inner side wall of the dialyzer body 1 The dialyzer body 1 has two sides and the same structure; the side wall of the through hole 16 is fixedly connected with a sealing ring 17; the inner wall of the sealing ring 17 is slidably connected with a pull rod 18; the end of the pull rod 18 is fixedly connected with a second magnetic strip 19; the second magnetic strip 19 is magnetically connected to the first magnetic strip 15; when in use, after the cap is installed on the side wall of the dialyzer body 1, a certain suction force will be generated when the second magnetic strip 19 and the first magnetic strip 15 are close to each other, and the sealing gasket 14 will be pulled to one side of the second magnetic strip 19, and the slider 12 will slide in the guide rail 11, so that the sealing gasket 14 covers At the channel, when the dialyzer body 1 falls during transportation, the small sealing cap on the side wall of the dialyzer body 1 falls off due to vibration, and the sealing pad 14 can prevent the liquid in the dialyzer body 1 from flowing out to the outside through the channel. When it is necessary to inject liquid into the dialyzer body 1 through the channel on the side wall of the dialyzer body 1, the pull rod 18 is held and pulled to move the second magnetic strip 19 away from the first magnetic strip 15. Under the elastic force of the first spring 13, the sealing pad 14 is pulled to reset, so that the channel is opened, and then the dialyzer can be injected through the channel. Liquid is injected into the dialyzer body 1, and due to the full fit between the pull rod 18 and the sealing ring 17, a certain friction force is generated, so that the pull rod 18 will not slide on the inner wall of the sealing ring 17, and the liquid will not flow out to the outside through the through hole 16. In this process, when the dialyzer falls during transportation, the cap of the dialyzer is easily removed, causing liquid leakage in the dialyzer and affecting the detection effect of the liquid inside the dialyzer. At this time, the channel is blocked by the sealing pad 14, thereby playing a role in preventing leakage when the dialyzer body 1 falls during transportation.

[0030] Further, such as Figure 1 , Figure 6 , Figure 7As shown, the side wall of the dialyzer body 1 is provided with a plurality of bases 2; the bases 2 are evenly distributed on the side wall of the dialyzer body 1 and have the same structure; a pair of columns 21 are fixedly connected to the side wall of the base 2; the columns 21 are symmetrically arranged on both sides of the base 2 and have the same structure; a second spring 22 is sleeved on the outer side of the column 21; the second spring 22 is fixedly connected to the base 2; an annular block 23 is fixedly connected to the end of the second spring 22; the annular block 23 is slidably matched with the column 21; the side wall of the annular block 23 is fixedly connected to the same baffle 24; a pair of sliding holes 25 are symmetrically opened on the side wall of the baffle 24; when in use, when the dialyzer body 1 falls during transportation, the falling The impact force will cause a certain impact force on the baffle 24, causing the second spring 22 to perform telescopic movement, the annular block 23 will slide on the side wall of the column 21, and the column 21 will pass through the side wall of the sliding hole 25, and then the impact force will be buffered under the elastic force of the second spring 22 to protect the dialyzer body 1. In this process, the dialyzer body 1 can be reduced in the event of falling, which may cause the dialyzer body 1 to be damaged easily, thereby causing a certain impact on the service life of the dialyzer body 1. At this time, through the mutual cooperation of the baffle 24 and the second spring 22, the dialyzer body 1 can play a protective buffering role when it falls, thereby increasing the service life of the dialyzer body 1.

[0031] Further, such as Figure 4 As shown, the side wall of the sealing gasket 14 is provided with a first groove 3; the side wall of the first groove 3 is fixedly connected to a spring rod 31; the end of the spring rod 31 is fixedly connected to a protrusion 32; the inner side wall of the dialyzer body 1 is provided with a plurality of second grooves 33; the second grooves 33 are evenly distributed on the inner side wall of the dialyzer body 1 and have the same structure; the side wall of the second groove 33 is fixedly connected to a magnetic ball 34; when in use, when the sealing gasket 14 covers the channel, the first magnetic strip 15 and the magnetic ball 34 are attracted to each other by their proximity, so that the sealing gasket 14 is fully fitted with the inner side wall of the dialyzer body 1, and at the same time, due to The protrusion 32 has a certain magnetic force, and the magnetic ball 34 will attract the protrusion 32, pulling the protrusion 32 toward the side wall of the second groove 33, and the elastic force of the spring rod 31 can also push the protrusion 32, so that the protrusion 32 is stuck in the side wall of the second groove 33. In this process, the vibration caused by the fall of the dialyzer body 1 can be reduced, which can easily cause the first spring 13 to shake, causing the sealing gasket 14 to shake, thereby making it easy for liquid to flow into the channel. At this time, the protrusion 32 is stuck in the side wall of the second groove 33, thereby increasing the stability of the sealing gasket 14 during use and improving the sealing effect.

[0032] Further, such as Figure 1 , Figure 6 , Figure 8As shown, the side wall of the dialyzer body 1 is fixedly connected with a plurality of mounting blocks 4; the mounting blocks 4 are evenly distributed on the side wall of the dialyzer body 1 and have the same structure; the side wall of the mounting blocks 4 is provided with a card slot 41; the side wall of the base 2 is fixedly connected with a pair of brackets 42; the brackets 42 are symmetrically arranged on both sides of the base 2 and have the same structure; the side wall of the bracket 42 is hinged with a card block 43; when in use, the staff holds the base 2, places the base 2 on the side wall of the dialyzer body 1, and applies a certain force to the base 2, at this time, the card block 43 is squeezed by the mounting block 4 and will be stretched open, when the card block 43 moves to a certain extent, it will automatically reset under the action of the internal torsion spring at the hinge of the card block 43, so that it is stuck in the side wall of the card slot 41, so that the base 2 can be fixed, in this process, it can reduce the difficulty of disassembling and replacing the baffle 24 when it is damaged during long-term use, resulting in a certain increase in workload, at this time, the card block 43 is stuck in the card slot 41 for fixing, thereby playing the role of facilitating disassembly and replacement of the baffle 24 when it is damaged.

[0033] Further, such as Figure 6 , Figure 8 As shown, the side wall of the bracket 42 is fixedly connected with an insertion rod 5; the side wall of the mounting block 4 is provided with a positioning hole 51; when in use, by placing the base 2 on the side wall of the dialyzer body 1, the insertion rod 5 will first contact the positioning hole 51, and under the action of the inclined surface of the positioning hole 51, the insertion rod 5 can slide toward the middle of the positioning hole 51, so that the insertion rod 5 is inserted into the side wall of the positioning hole 51, and then the block 43 can be inserted into the side wall of the slot 41. In this process, when the base 2 is installed, it is difficult to align the block 43 with the slot 41, which makes the process of the block 43 being inserted into the side wall of the slot 41 more complicated. At this time, the insertion rod 5 is inserted into the side wall of the positioning hole 51, thereby playing a limiting role when the base 2 is installed.

[0034] Further, such as Figure 7 As shown, a plurality of cleaning brushes 6 are evenly fixedly connected to the side wall of the annular block 23; when in use, the cleaning brush 6 can clean the side wall of the column 21 and sweep away the dust and impurities attached to the side wall of the column 21 during the sliding process of the annular block 23 on the side wall of the column 21. In this process, the dust and impurities attached to the side wall of the column 21 can be reduced, resulting in obstruction between the annular block 23 and the column 21, thereby causing a certain influence on the sliding effect between the annular block 23 and the column 21. At this time, the dust and impurities attached to the side wall of the column 21 are swept away by the cleaning brush 6, thereby playing a cleaning role on the column 21, and improving the smoothness of the sliding between the annular block 23 and the column 21.

[0035] Further, such as Figure 7As shown, the side wall of the cleaning brush 6 is fixedly connected with a connecting rod 7; the connecting rod 7 passes through the wall of the cleaning brush 6 and is fixedly connected thereto; when in use, during the cleaning process of the cleaning brush 6, the connecting rod 7 can fix the multiple cleaning brushes 6 together so that they are concentrated together during cleaning. In this process, the cleaning brush 6 can be reduced to be relatively scattered during cleaning, resulting in poor cleaning effect on the column 21, affecting the sliding effect between the annular block 23 and the column 21. At this time, the connecting rod 7 is set to increase the concentration of the cleaning brush 6 during cleaning and improve the cleaning effect.

[0036] Working principle: When in use, after the cap is installed on the side wall of the dialyzer body 1, a certain suction force will be generated when the second magnetic strip 19 and the first magnetic strip 15 are close to each other, and the sealing gasket 14 will be pulled to one side of the second magnetic strip 19, and the slider 12 will slide in the guide rail 11, so that the sealing gasket 14 covers the channel. Afterwards, when the dialyzer body 1 falls during transportation, the small sealing cap on the side wall of the dialyzer body 1 falls off due to vibration, and the sealing gasket 14 can prevent the liquid in the dialyzer body 1 from flowing out to the outside through the channel. When it is necessary to inject liquid into the dialyzer body 1 through the channel on the side wall of the dialyzer body 1, the pull rod 18 is held and pulled to move the second magnetic strip 19 and the first magnetic strip 15 away from each other, and the first spring 13 is elastic. Under the action of force, the sealing pad 14 will be pulled to reset and the channel will be opened. At this time, liquid can be injected into the dialyzer body 1 through the channel, and due to the full fit between the pull rod 18 and the sealing ring 17, a certain friction force will be generated, so that the pull rod 18 will not slide on the inner wall of the sealing ring 17, and the liquid will not flow out to the outside through the through hole 16. When in use, when the dialyzer body 1 falls during transportation, the impact force generated by the fall will cause a certain impact force on the baffle 24, causing the second spring 22 to perform telescopic movement, and the annular block 23 will slide on the side wall of the column 21, and the column 21 will pass through the side wall of the sliding hole 25. Then, under the elastic force of the second spring 22, the impact force will be buffered to protect the dialyzer body 1. When in use, when the sealing gasket 14 covers the channel, the first magnetic strip 15 and the magnetic ball 34 are attracted to each other when they are close to each other, so that the sealing gasket 14 and the inner wall of the dialyzer body 1 are fully fitted. At the same time, due to the certain magnetic force in the protrusion 32, the magnetic ball 34 and the protrusion 32 are attracted to each other, and the protrusion 32 is pulled toward the side wall of the second groove 33, and the elastic force of the spring rod 31 can also push the protrusion 32, so that the protrusion 32 is stuck in the side wall of the second groove 33. When in use, the staff holds the base 2, places the base 2 on the side wall of the dialyzer body 1, and applies a certain force to the base 2. At this time, the clamping block 43 is squeezed by the mounting block 4 and is stretched open. When the clamping block 43 moves to a certain extent, the clamping block 43 is The block 43 will automatically reset under the action of the internal torsion spring at the hinge, so that it can be stuck in the side wall of the card slot 41, so that the base 2 can be fixed. When in use, by placing the base 2 on the side wall of the dialyzer body 1, the insertion rod 5 will first contact the positioning hole 51, and under the action of the inclined surface of the positioning hole 51, the insertion rod 5 can slide to the middle of the positioning hole 51, so that the insertion rod 5 is inserted into the side wall of the positioning hole 51, and then the card block 43 can be stuck in the side wall of the card slot 41. When in use, during the process of the annular block 23 sliding on the side wall of the column 21, the cleaning brush 6 can clean the side wall of the column 21 and sweep away the dust and impurities attached to the side wall of the column 21. When in use, during the cleaning process of the cleaning brush 6, the connecting rod 7 can fix and connect multiple cleaning brushes 6.Keep them together when cleaning.
