Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hepatitis B virus adsorption device. Background Technology

[0002] To block the replication of the hepatitis B virus in the blood, the blood needs to be filtered to remove the virus. During blood filtration, the hepatitis B virus and beneficial proteins in the blood are adsorbed together, which affects the patient's absorption of nutrients during treatment. As a result, the patient's body does not receive enough nutritional supplements in the middle of treatment, which lowers their immunity.

[0003] Current adsorption devices utilize molecular sieve technology to draw blood into the adsorption module for hepatitis B virus adsorption. The adsorbed blood is then pumped back into the patient. However, the following problems exist in actual operation:

[0004] 1. During use, the interface between the hemodialysis tubing and the adsorption component is usually quite fragile and prone to bending. When the hemodialysis tubing is bent, blood flow may be obstructed, which will affect the efficiency of blood entering the adsorption component and reduce the adsorption speed of hepatitis B virus.

[0005] 2. There is a possibility of accidental contact with the adsorption component during use. The adsorption component may move even with slight impact, which may increase the possibility of the hemodialysis tube falling out of the adsorption component and thus affect the adsorption of hepatitis B virus. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this invention is to provide a hepatitis B virus adsorption device that minimizes the risk of bending at the connection between the hemodialysis tube and the installation interface during the adsorption process, thereby preventing blood flow obstruction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A hepatitis B virus adsorption device includes an adsorption component for adsorbing the virus in blood and a detachable mounting component covering the adsorption component. The adsorption component includes a flow tube, a detachable filter sub-component disposed within the flow tube, and a pair of mounting interfaces symmetrically disposed at the upper and lower ends of the flow tube for communicating with two hemodialysis tubes respectively. The mounting component includes a pair of symmetrical mounting shells fastened to the left and right sides of the flow tube, a pair of symmetrical clamping sub-components disposed on opposite sides of the two mounting shells, and a fixing sub-component disposed between the mounting shell and the flow tube for fixing the mounting tube. Each set of clamping sub-components includes a pair of symmetrically rotatably disposed at the upper and lower ends of the mounting shell. The two clamping plates in each set of clamping sub-components have an arc-shaped portion at one end away from each other.

[0009] More preferably, the fixing sub-assembly includes a fixing ring that is fixed around the outside of the flow tube and a pair of C-shaped elastic limiting rings that are fixed on the inner surface of the corresponding mounting housing and cooperate with the fixing ring to fix the mounting housing.

[0010] More preferably, the filter sub-assembly includes a support rod fixed inside the flow tube, a filter sleeve detachably disposed inside the support rod, an adsorption sleeve disposed outside the filter sleeve, a vibration sleeve disposed outside the adsorption sleeve, and a guide ring surrounding and fixed to the upper part of the flow tube; the guide ring gradually slopes downward from the outside to the inside, and the inner wall of the guide ring is aligned with the inner wall of the filter sleeve.

[0011] More preferably, the vibrating sleeve includes a pair of mounting rings symmetrically arranged around and fixed outside the adsorption sleeve, a filter bag arranged around and fixed between the two mounting rings, and a number of vibrating sub-assemblies spaced apart and fixed inside the filter bag; the vibrating sub-assemblies include a placement bag fixed inside the filter bag, a pair of vibrating balls placed inside the placement bag, and a connecting rope fixed between the two vibrating balls.

[0012] More preferably, each of the aforementioned mounting housings has a limiting hook fixed to its outer side.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting two clamping plates at the same end of the two mounting shells, can clamp the hemodialysis tube connected to the mounting interface, and avoid the situation where the hemodialysis tube located at the mounting interface is bent when the adsorption component adsorbs the hepatitis B virus in the patient's blood, which would reduce the rate at which blood enters the adsorption component and slow down the adsorption efficiency of hepatitis B virus.

[0015] 2. This utility model provides a pair of symmetrically interlocking mounting shells over the circulation tube. This protects the circulation tube and minimizes collisions during hepatitis B virus adsorption, reducing the possibility of the hemodialysis tube dislodging from the mounting interface due to tube displacement. This improves safety during hepatitis B virus adsorption. Furthermore, the mounting shells do not come into contact with blood, allowing for reuse and reducing production costs.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] A hepatitis B virus adsorption device includes an adsorption component 1 for adsorbing the virus in blood and a detachable mounting component 2 covering the outside of the adsorption component 1. The adsorption component 1 includes a flow tube 11, a detachable filter sub-component 12 disposed within the flow tube 11, and a pair of mounting interfaces 13 symmetrically disposed at the upper and lower ends of the flow tube 11 and respectively connected to two hemodialysis tubes. The mounting component 2 includes a pair of mounting shells 21 symmetrically fastened to the left and right sides of the flow tube 11, a pair of clamping sub-components 22 symmetrically disposed on opposite sides of the two mounting shells 21, and a fixing sub-component 12 disposed between the mounting shells 21 and the flow tube 11 for fixing the mounting tube. Each set of clamping sub-components 22 includes a pair of clamping plates 221 symmetrically rotatably disposed at the upper and lower ends of the mounting shells 21. The two clamping plates 221 in each set of clamping sub-components 22 have an arc-shaped portion 222 at one end away from each other.

[0024] By setting two clamping plates 221 at the same end of the two mounting shells 21, the hemodialysis tube communicating with the mounting interface 13 can be clamped, minimizing the risk of the hemodialysis tube at the mounting interface 13 bending during the adsorption of hepatitis B virus in the patient's blood by the adsorption component 1, which would reduce the rate at which blood enters the adsorption component 1 and slow down the adsorption efficiency of hepatitis B virus. By covering the flow tube 11 with a pair of symmetrically interlocking mounting shells 21, the flow tube 11 can be protected, minimizing collisions with the flow tube 11 during hepatitis B virus adsorption, thereby reducing the possibility of the hemodialysis tube falling out of the mounting interface 13 due to displacement of the flow tube 11, thus improving safety during the hepatitis B virus adsorption process. On the other hand, the mounting shells 21 do not come into contact with blood, so they can be reused, reducing production costs.

[0025] As a possible implementation of this solution, preferably, the fixing sub-assembly 23 includes a fixing ring 231 that surrounds and is fixed to the outside of the flow tube 11, and a pair of C-shaped elastic limiting rings 232 that are fixed to the inner surface of the corresponding mounting shell 21 and cooperate with the fixing ring 231 to fix the mounting shell 21. The cooperation between the C-shaped elastic limiting rings 232 and the fixing rings 231 can fix the position of the mounting shell 21, thereby avoiding shaking between the mounting shell 21 and the flow tube 11 as much as possible, thereby reducing the adverse effects of hepatitis B virus adsorption.

[0026] As a possible implementation of this solution, preferably, the filter sub-assembly 12 includes a support rod 121 fixed inside the flow tube 11, a filter sleeve 122 detachably disposed inside the support rod 121, an adsorption sleeve 123 sleeved outside the filter sleeve 122, a vibrating sleeve 124 sleeved outside the adsorption sleeve 123, and a guide ring 125 surrounding and fixed to the upper part of the flow tube 11; the guide ring 125 gradually slopes downward from the outside to the inside, and the inner wall of the guide ring 125 is aligned with the inner wall of the filter sleeve 122; the filter sleeve 122 can first intercept impurities in the blood, the adsorption sleeve 123 can adsorb hepatitis B virus in the blood, and the setting of the vibrating sleeve 124 can vibrate the adsorption sleeve 123 and the filter sleeve 122, so as to avoid some impurities remaining on the filter sleeve 122 and the adsorption sleeve 123 and affecting the blood flow.

[0027] As a possible implementation of this solution, preferably, the vibrating sleeve 124 includes a pair of mounting rings 1241 symmetrically arranged around and fixed to the outside of the adsorption sleeve 123, a filter bag 1242 arranged around and fixed between the two mounting rings 1241, and a plurality of vibrating sub-assemblies 1243 spaced apart and fixed inside the filter bag 1242; the vibrating sub-assemblies 1243 include a placement bag 12431 fixed inside the filter bag 1242, a pair of vibrating balls 12432 placed inside the placement bag 12431, and a connecting rope 12433 fixed between the two vibrating balls 12432; by setting the two vibrating balls 12432 and the connecting rope 12433, when blood passes through the vibrating sleeve 124, the two vibrating balls 12432 can collide, thereby causing the adsorption sleeve 123 and the filter sleeve 122 to vibrate.

[0028] As a possible implementation of this solution, preferably, each of the mounting housings 21 is fixedly provided with a limiting hook 211 on its outer side. The limiting hook 211 can facilitate the separation of the two mounting housings 21 to the sides, thereby facilitating the disassembly of the mounting housings 21. On the other hand, the limiting hook 211 can be hung in a certain place to limit the position of the device.

[0029] The working principle of this device is as follows:

[0030] When it is necessary to adsorb hepatitis B virus from a patient, connect both ends of the hemodialysis tube to the two mounting interfaces 13 respectively. Then, move the two mounting shells 21 from both sides toward the flow tube body 11 until the two mounting shells 21 are fastened together and cover the outside of the flow tube body 11. At this time, the C-type elastic limiting ring 232 is fastened to the fixing ring 231. At the same time, the two clamping plates 221 located on the same side of the mounting interface 13 clamp the hemodialysis tube from both sides. Then, the device can be hung in the placement area by the limiting hook 211.

[0031] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
