Technical Field

[0001] The utility model relates to the field of urokinase, in particular to a high-efficiency adsorption bag for urokinase. Background Technique

[0002] Urokinase is an enzyme protein isolated from the urine of healthy people or obtained from human kidney tissue culture. It has high medical value. In the prior art, urokinase is generally extracted by the adsorption method. Mainly, the resin is put into urine for adsorption. After the adsorption is completed, the resin can be taken out to complete the adsorption.

[0003] When adsorbing urokinase, an adsorption bag is often needed. The adsorption bag can provide a place for adsorption. When in use, the sample can be directly introduced into the adsorption bag, and then the filter cartridge filled with resin is inserted into the bag body for adsorption. However, since the total amount of the sample is uncertain each time, after the filter cartridge is inserted into the bag body, the upper liquid level of the sample may be lower than the upper surface of the resin. In this way, when adsorbing, the resin cannot be fully engaged in the adsorption operation, which results in a low adsorption efficiency of the overall device. Therefore, a high-efficiency adsorption bag for urokinase is proposed to solve the above problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 As an embodiment provided by the present utility model: A highly efficient urokinase adsorption bag includes a bag body 1 for accommodating a sample. The bag body 1 is made of transparent plastic material and has a folding mark at its middle position, through which the bag body 1 can be folded and contracted. At the top of the bag body 1, there is a liquid inlet 2 for introducing the sample into the interior of the bag body 1. At the right end of the liquid inlet 2, there is a handle 3 fixedly connected for facilitating the movement of the whole device. At the top of the liquid inlet 2, there is an adsorption component 7 for accommodating resin. The adsorption component 7 includes a filter cartridge 72 for containing resin. The filter cartridge 72 is a prior art, and different-sized filter cartridges 72 can be selected according to different usage situations during specific use. Due to the prior art, this case will not be described in excessive detail. The filter cartridge 72 is inserted into the inner wall of the bag body 1. At the right end of the bag body 1, there is an adjustment component 6 for adjusting the overall height of the bag body 1. The adjustment component 6 includes a fixed plate 66. The left end of the fixed plate 66 is fixedly connected to the right end of the bag body 1. At a position near the top of the right end of the bag body 1, there is a fixed sleeve 61 for supporting the clamping block 62. The fixed plate 66 penetrates and slides inside the inner wall of the fixed sleeve 61. By adjusting the relative position between the fixed plate 66 and the fixed sleeve 61, the overall height of the bag body 1 can be adjusted.

[0031] Refer to Figure 1 - Figure 3The adsorption assembly 7 also includes a support ring 71 for supporting the filter cartridge 72. The bottom end of the support ring 71 is fixedly connected to the top end of the filter cartridge 72. The outer diameter of the support ring 71 is larger than the liquid inlet 2, which can be used to prevent the filter cartridge 72 from falling completely into the interior of the bag body 1. The top end of the liquid inlet 2 is fixedly connected to a plastic buckle 75 for fixing the support ring 71. The plastic buckle 75 has elastic deformation ability and will undergo elastic deformation when squeezed. By using the plastic buckle 75 to hook the sealing cover 74, the bottom end of the sealing cover 74 can be tightly attached to the top end of the liquid inlet 2. The top end of the plastic buckle 75 is fixedly connected to a protrusion 76 for facilitating the operator to move the plastic buckle 75. The bottom end of the support ring 71 is fixedly connected to a rubber ring 73 for increasing the sealing performance of the device. The top end of the support ring 71 is threadedly connected to a sealing cover 74 for closing the top opening of the support ring 71.

[0032] Reference Figure 1 - Figure 3 The adjusting assembly 6 also includes a block 62 for fixing the fixing plate 66. The block 62 penetrates and is slidably connected to the right end of the fixing sleeve 61. The right end of the fixing plate 66 is provided with a fixing groove 67 for accommodating the block 62. The fixing groove 67 and the block 62 are adapted. When the block 62 is inserted into the fixing groove 67, the fixing plate 66 will be fixed and cannot move up and down. The right end of the fixing sleeve 61 is fixedly connected to a dial plate 65 near the top of the block 62 for facilitating the operator to move the fixing sleeve 61. The right end of the block 62 is fixedly connected to a fixing spring 64 for pushing the block 62. The right end of the fixing spring 64 is fixedly connected to the left end of the dial plate 65. The fixing spring 64 will always push the block 62 to the left. The right end of the block 62 is fixed A shift block 63 is connected to facilitate the operator to move the card block 62. The shift block 63 is set to an L shape. By shifting the shift block 63, the card block 62 can be driven to move to the right and out of the fixed groove 67. The adjustment component 6 also includes a slide plate 68 for supporting the vertical contraction of the bag body 1. The right end of the slide plate 68 is fixedly connected to the left end of the bag body 1. The outer wall of the slide plate 68 is sleeved with a sliding sleeve 69 for limiting the movement trajectory of the slide plate 68. The right end of the sliding sleeve 69 is fixedly connected to the left end of the bag body 1. Due to the restrictions of the slide plate 68 and the sliding sleeve 69, the bag body 1 can only contract vertically up and down. The front end of the bag body 1 is fixedly connected with a discharge port 4 for facilitating the discharge of samples. The front end of the discharge port 4 is threadedly connected with a closing cover 5 for closing the discharge port 4.

[0033] Working principle: When adsorption is required, the sample can be introduced into the bag body 1 first, and then the resin can be loaded into the filter cartridge 72, and then the filter cartridge 72 can be inserted into the bag body 1. At this time, the plastic buckle 75 will hook the support ring 71 under the support of its own elastic deformation, and then the support ring 71 will be fixed. Then half of the sealing cover 74 can be screwed on the top of the support ring 71, and then the height of the bag body 1 can be adjusted.

[0034] When adjusting the height of the bag body 1, it is necessary to first hold the dial plate 65 and the sliding sleeve 69 simultaneously. Then, the dial block 63 can be toggled to drive the clamping block 62 to move to the right and disengage from the inside of the fixing groove 67. Subsequently, the dial plate 65 and the sliding sleeve 69 can be moved up and down to drive the bag body 1 to fold and contract along the folding line. When it is observed that the liquid level inside the bag body 1 rises above the upper surface of the resin, the clamping block 62 can be released. The fixing spring 64 will push the clamping block 62 to make it re-engage into the inside of the fixing groove 67 to re-fix the fixing plate 66. Then, the sealing cover 74 can be rotated to completely tighten it. In this way, the static adsorption operation can be started.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
