[0002] Hemoperfusion devices are mainly used for the adsorption of molecular toxins in acute and chronic drug poisoning, uremia, and the adsorption of pathogenic factors in liver disease and immunity.

[0003] During practical use, heparin needs to be injected into the blood perfusion device to achieve an anticoagulant effect and prevent blood clotting. However, during the injection, the upper cover of the blood perfusion device needs to be opened, and the injection process requires a long time. During the injection process, dust, bacteria and other harmful substances will inevitably fall into the blood perfusion device, affecting the growth and use of the blood perfusion device, posing certain safety hazards and making it inconvenient to use.

[0004] Existing hemoperfusion devices do not have a good anti-bacterial function, resulting in dust and live bacteria falling into the hemoperfusion device when injecting heparin, affecting the normal use of the hemoperfusion device and causing inconvenience to hemoperfusion.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] A sterile blood perfusion device, comprising a perfusion assembly 1; the perfusion assembly 1 comprises: a blood perfusion device 11, each provided with a cover 12 on both sides; a sealing cover 13, disposed on opposite sides of the two covers 12, with the inner side walls of the two sealing covers 13 being threadedly connected to the outer side walls of the liquid inlet and liquid outlet on the two covers 12; the device is characterized in that: a disassembly assembly 2 is provided on the side of the blood perfusion device 11; the disassembly assembly 2 comprises: a housing 1 21 fixedly connected to the side of the blood perfusion device 11; a housing 2 22 disposed on the inner side wall of the housing 1 21; The ring body 23 is fixedly connected to the side of the shell 2 22; the plug 24 is embedded in the inner wall of the shell 22; the buckle 25 is symmetrically fixedly connected to the side of the ring body 23; the slot 26 is symmetrically opened on the side of the shell 1 21, and the two buckles 25 are respectively embedded in the two slots 26; the disassembly component 2 also includes: a block 27, symmetrically arranged on the inner wall of the shell 22, and the two blocks 27 are embedded in the outer wall of the plug 24; the disassembly component 2 also includes: a chamfer 28, opened on the outer wall of the plug 24.

[0027] See Figure 1-2When in use, when it is necessary to inject heparin into the blood perfusion device 11, the syringe is directly inserted into the ring body 1 23, and the syringe is sequentially passed through the shell 2 22, the rubber plug 24, the shell 1 21 and the outer wall of the blood perfusion device 11, so that the syringe needle is embedded in the blood perfusion device 11. After the heparin is directly injected into the blood perfusion device 11, the syringe is withdrawn to complete the injection. When the rubber plug 24 is not needed, it plays a role in sealing the blood perfusion device 11. When the injection is needed, it does not affect the syringe passing through the rubber plug 24, achieving a sealed injection and a bacteria-releasing effect. When the rubber plug 24 needs to be replaced, the ring body 1 23 is directly pulled outward, so that the ring body 1 23 drives the shell 2 22 and the rubber plug 24. The plug 24 and the two clips 25 slide outward until the two clips 25 are disengaged from the two slots 26. Then, the shell 22 can be taken out from the shell 1 21, and the plug 24 in the shell 22 can be taken out. After replacement, the shell 22 can be embedded into the shell 1 21 again, and the two clips 25 can be embedded in the two slots 26 respectively, so that the plug 24 is tightly attached to the inner side of the shell 1 21 to achieve a sealing effect, and the replacement is completed. During use, the block 27 prevents the plug 24 from sliding out from the inner wall of the shell 22 when the shell 22 is taken out, which has a limiting effect on the plug 24 and does not affect the normal installation of the plug 24. During installation, it is convenient for the plug 24 to be embedded in the shell 2 22, which is convenient for use.

[0028] Example 2

[0029] The limiting function is added based on the first embodiment;

[0030] The outer wall of the second shell 22 is provided with a limit assembly 3; the limit assembly 3 includes: a groove body 31, which is opened on the outer wall of the groove body 31; a rod body 32, which is symmetrically fixedly connected to the groove body 31, and the two blocking blocks 27 are respectively slidably connected to the two rod bodies 32; a spring 33, which is sleeved on the outer walls of the two rod bodies 32, and the two ends of the spring 33 are respectively fixedly connected to the shell 1 21 and the blocking blocks 27; the limit assembly 3 also includes: a second ring body 34, which is slidably connected to the groove body 31, and the inner wall of the second ring body 34 is connected to the back faces of the two blocking blocks 27; the limit assembly 3 also includes: a slide groove 35, which is symmetrically opened on the inner wall of the first shell 21, and the back faces of the two blocking blocks 27 respectively pass through the outer wall of the second ring body 34, and the back faces of the two blocking blocks 27 are respectively embedded in one of the slide grooves 35; the outer wall of the second shell 22 and the inner wall of the first shell 21 are tightly attached, and the side surface of the rubber plug 24 is located on the left side of the second shell 22.

[0031] See Figure 1-2When in use, when it is necessary to remove the plug 24, the two blocks 27 can be pulled outward, and the two blocks 27 slide on the outer walls of the two rods 32 while squeezing the two springs 33, so that the two blocks 27 drive the plug 24 to slide out from the inside of the shell 22, making it convenient to disassemble the plug 24, and the rebound force of the two springs 33 resets the two blocks 27, without affecting the normal installation of the plug 24 and the limiting effect of the blocks 27 on the plug 24; when in use, pushing the ring body 24 can achieve The second ring body 34 drives the two blocks 27 to slide to the left or right, which is convenient for use. When using the disassembly component 2 for installation, the second shell 22 is embedded in the first shell 21, and the two blocks 27 are respectively embedded in the two slide grooves 35 to fix the circumferential angle of the second shell 22, so that the two buckles 25 are conveniently embedded in the two slots 26, thereby improving the practicality of the device. When in use, the seal between the second shell 22 and the first shell 21 and the seal between the rubber plug 24 and the first shell 21 are improved, thereby improving the sealing effect of the device.
