Description

Technical Field

[0001] The invention relates to the technical field of medical care products, and in particular to a filter for treating coronary heart disease. Background Art

[0002] Coronary atherosclerotic heart disease (CHD) is a disease caused by lipids in the blood deposited on the smooth inner wall of the arteries due to abnormal lipid metabolism. Some atherosclerotic lipid substances in the inner wall of the arteries accumulate to form white plaques, which are called atherosclerotic lesions. These plaques gradually increase and cause the narrowing of the arterial cavity, obstructing blood flow, leading to ischemia of the heart and causing angina pectoris.

[0003] At present, there are various methods for treating coronary heart disease at home and abroad, including dilating coronary arteries and preventing the formation and aggregation of blood clots. Usually, a conventional filter with only one blood filtration membrane is used to filter the blood. However, after a certain period of use, the relevant conventional filter is prone to accumulate a large amount of lipid substances, making it itself a "thrombus". Therefore, the relevant conventional filter needs to be replaced frequently during use, which is not only inconvenient to use, but also fails to achieve a good blood filtration effect.

[0004] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and through retrieval and novelty search, gradually conceived and designed this application to solve related technical problems. Summary of the invention

[0005] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the purpose of the present invention is to provide a filter for treating coronary heart disease.

[0006] To achieve one of the above purposes, a coronary heart disease treatment filter according to an embodiment of the present invention includes a filter cartridge for filtering blood, which has a liquid inlet at the upper end and a liquid outlet at the lower end;

[0007] A blood guide plate, a first filter membrane, a second filter membrane and a third filter membrane are sequentially arranged inside the filter cartridge from top to bottom; the blood guide plate is tilted toward the lower left side of the filter cartridge, and a blood guide hole penetrating the upper and lower end surfaces of the blood guide plate is provided near the lower left end of the blood guide plate; the first filter membrane, the second filter membrane and the third filter membrane are all tilted toward the lower right side of the filter cartridge.

[0008] In addition, the coronary heart disease treatment filter according to the above embodiment of the present invention may also have the following additional technical features:

[0009] According to one embodiment of the present invention, the pore size of the first filter membrane is larger than the pore size of the second filter membrane, and the pore size of the second filter membrane is larger than the pore size of the third filter membrane.

[0010] According to one embodiment of the present invention, it further comprises a liquid storage dish for collecting blood, wherein a connecting port is provided on the upper portion of the liquid storage dish, and the connecting port is detachably connected to the liquid outlet.

[0011] According to one embodiment of the present invention, the liquid storage vessel comprises a liquid storage cylinder with an open upper portion and a cylinder cover detachably covering the open upper portion of the liquid storage cylinder;

[0012] The connecting port is upwardly arranged in the middle of the top of the cylinder cover, and a liquid taking port is arranged to the left in the middle of the left outer wall of the cylinder cover, and a sealing cover A is detachably covered at the liquid taking port.

[0013] According to one embodiment of the present invention, a fourth filter membrane having a pore size equal to that of the third filter membrane is fixedly disposed on the left inner portion of the cylinder cover and inclined toward the lower left;

[0014] The upper end of the fourth filter membrane is connected to the left middle part of the inner top surface of the tube cover, and the lower end is connected to the lower part of the left inner wall of the tube cover, so that the upper left part of the tube cover forms a blood filtering cavity connected to the liquid intake port.

[0015] According to one embodiment of the present invention, it further comprises a detachable cap covering the outside of the liquid inlet;

[0016] The right part of the cap is upwardly connected with a blood guide tube which penetrates into the interior thereof, and the upper end of the blood guide tube is provided with a connector adapted to be connected with a blood extraction line for treating coronary heart disease.

[0017] According to one embodiment of the present invention, the cap is higher on the left and lower on the right, and the left part of the cap is upwardly connected to a drain head that penetrates into the interior thereof, the drain head has drain cotton embedded therein, and a detachable sealing cover B is provided on the outside.

[0018] According to one embodiment of the present invention, the device for removing lipid substances in the blood also includes a fat removal pusher containing a fat removal liquid;

[0019] A hollow connecting seat is connected to the right at the upper middle part of the right side wall of the filter cartridge and penetrates into the interior thereof. The height of the left end of the hollow connecting seat is flush with the height of the middle part of the lower bottom surface of the blood guide plate. A Luer connector is provided at the left end of the fat removal injector, and the Luer connector is plug-connected to the right end of the hollow connecting seat.

[0020] According to one embodiment of the present invention, a one-way check valve is provided inside the hollow connecting seat to allow the liquid medicine to enter the filter cartridge from the outside to the inside.

[0021] According to one embodiment of the present invention, the one-way check valve comprises a hollow cylindrical valve body with openings at both left and right ends, a valve core and a pressure spring;

[0022] The hollow cylindrical valve body has a liquid flow cavity with an inner diameter larger than the inner diameters of the openings at its left and right ends opened in the middle along the left and right directions; the valve core has an outer diameter smaller than the inner diameter of the liquid flow cavity, and the right end surface periphery of the valve core is tightly against the right inner wall of the liquid flow cavity, the left end surface of the valve core is connected to the right end of the top pressure spring; the left end of the top pressure spring is fixed to the left inner wall of the liquid flow cavity;

[0023] When the valve core is pushed to the left by a certain force, the top pressure spring is compressed, the valve core moves leftward along the liquid medicine flow chamber, and the openings at both ends of the hollow cylindrical valve body are connected to the liquid medicine flow chamber.

[0024] The beneficial effects of the present invention are:

[0025] First, in the specific implementation of the coronary heart disease treatment filter provided by the present application, the blood guide plate is arranged to be inclined toward the lower left side of the filter cartridge to guide the blood downward, so as to avoid the blood splashing upward inside the filter cartridge as much as possible. The blood transported to the filter cartridge is filtered through the first filter membrane, the second filter membrane and the third filter membrane for three-stage filtration, so that the lipid substances in the patient's blood can be better reduced, so that when the processed blood is subsequently returned to the patient's blood vessels, the blood contains less fat, which can better alleviate the accumulation of blood clots in the patient's blood vessels.

[0026] Second, compared with the traditional horizontal filter membrane arrangement, the present application sets the first filter membrane, the second filter membrane and the third filter membrane in an inclined manner toward the lower right side of the filter cartridge. In this way, the patient's blood transported into the filter cartridge can flow over a larger area on its upper surface, so that per unit volume of the filter cartridge, the present application has an excellent filtering effect on the patient's blood, and the filtered lipid substances will also flow to the lower right part of the first filter membrane, the lower right part of the second filter membrane and the lower right part of the third filter membrane due to gravity, so that the upper left part of the first filter membrane, the upper left part of the second filter membrane and the upper left part of the third filter membrane are not easily blocked by the filtered lipid substances, so that per unit time, the present application has a long service life and can greatly reduce the number and frequency of replacements during use.

[0027] Third, by setting the fourth filter membrane, the lipid substances in the patient's blood can be further intercepted and filtered out, so that the blood flowing out of the liquid collection port and returned to the patient's blood vessels will be clearer, and the fat content can be reduced to a lower level, so that the overall use effect of this application is better.

[0028] Fourthly, the present application sets up the degreasing injector, and when it is operated regularly or irregularly, it is convenient to push the degreasing liquid stored therein into the filter cartridge to remove the lipid substances in the patient's blood accumulated on the upper surfaces of the first filter membrane, the second filter membrane and the third filter membrane, so as to avoid as much as possible the accumulation of a large amount of lipid substances in the patient's blood on the upper surfaces of the first filter membrane, the second filter membrane and the third filter membrane, causing the entire surface to be blocked. In other words, through this optimized design, the overall use effect of the present application is better and the overall service life is longer.

[0029] Fifth point, since the height of the left end of the hollow connecting seat is flush with the height of the middle part of the lower bottom surface of the blood guide plate, when the degreasing injector is controlled regularly or irregularly to push the degreasing liquid stored therein into the filter cartridge, the degreasing liquid pushed out will be splashed to the middle part of the lower bottom surface of the blood guide plate as much as possible in advance, and then, it will be reflected and refracted by the lower bottom surface of the blood guide plate, so that the degreasing liquid pushed out from the degreasing injector will be fully and as much as possible reflected and refracted in a divergent shape to each position on the upper surface of the first filter membrane, so as to remove the lipid substances in the patient's blood accumulated at each position on the upper surface of the first filter membrane as much as possible, so that the lipid substances in the patient's blood accumulated on the upper surface of the first filter membrane can be removed quickly and efficiently.

[0030] Sixth point, since the upper surface of the first filter membrane can be fully splashed with the degreasing liquid, the degreasing liquid flowing down through the first filter membrane can fully and as much as possible drip onto each position on the upper surface of the second filter membrane and can also fully and as much as possible drip onto each position on the upper surface of the third filter membrane, so that the lipid substances in the patient's blood accumulated on the upper surface of the second filter membrane and the lipid substances in the patient's blood accumulated on the upper surface of the third filter membrane can also be removed quickly and efficiently.

[0031] Seventhly, by providing the one-way check valve, it is possible to better prevent the patient's blood retained in the filter cartridge from overflowing, thereby better preventing cross infection of blood.

[0032] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0093] The coronary heart disease treatment filter 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0094] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a coronary heart disease treatment filter 1000 provided according to an embodiment of the present invention comprises a filter cartridge 10 for filtering blood, which has a liquid inlet 101 at the upper end and a liquid outlet 102 at the lower end;

[0095] Among them, the inside of the filter cartridge 10 is provided with a blood guide plate 103, a first filter membrane 104, a second filter membrane 105 and a third filter membrane 106 in sequence from top to bottom; the blood guide plate 103 is tilted toward the lower left side of the filter cartridge 10, and a blood guide hole 1031 is provided on the blood guide plate 103 near its lower left end, which passes through its upper and lower end surfaces; the first filter membrane 104, the second filter membrane 105 and the third filter membrane 106 are all tilted toward the lower right side of the filter cartridge 10.

[0096] Based on the above, it is clear that when the present application is implemented, it is mainly used as a filter 1000 for treating coronary heart disease.

[0097] Specifically, when applying the present application, when the blood output from the patient's body enters the filter cartridge 10 through the liquid inlet 101, it can flow down along the blood guide plate 103, and flow out from the blood guide hole 1031 and drip onto the first filter membrane 104. The blood filtered by the first filter membrane 104 will drip down onto the second filter membrane 105. The blood filtered by the second filter membrane will drip down onto the third filter membrane 106. The blood filtered by the third filter membrane 106 will drip down to be discharged from the liquid outlet 102. In this way, the present application can be easily used.

[0098] Obviously, the use of this application will have the following technical effects:

[0099] On the one hand, the blood guide plate 103 is arranged to be inclined toward the lower left side of the filter cartridge 10 to guide the blood downward, so as to avoid the blood splashing upward inside the filter cartridge 10 as much as possible.

[0100] On the other hand, the blood transported into the filter cartridge 10 is filtered through the first filter membrane 104, the second filter membrane 105 and the third filter membrane 106, which can effectively reduce the lipid substances in the patient's blood. When the processed blood is subsequently returned to the patient's blood vessels, the blood contains less fat, which can effectively alleviate the accumulation of blood clots in the patient's blood vessels.

[0101] Furthermore, compared to the conventional method of setting the filter membrane horizontally, the present application sets the first filter membrane 104, the second filter membrane 105 and the third filter membrane 106 to be tilted toward the lower right side of the filter cartridge 10. In this way, the patient's blood transported into the filter cartridge 10 can flow over a larger area on its upper surface, so that per unit volume of the filter cartridge 10, the present application has an excellent filtering effect on the patient's blood, and the filtered lipid substances will also flow to the lower right part of the first filter membrane 104, the lower right part of the second filter membrane 105 and the lower right part of the third filter membrane 106 due to gravity, so that the upper left part of the first filter membrane 104, the upper left part of the second filter membrane 105 and the upper left part of the third filter membrane 106 are not easily blocked by the filtered lipid substances, so that per unit time, the present application has a long service life and can greatly reduce the number and frequency of replacements during use.

[0102] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0103] Furthermore, in a specific implementation, according to an embodiment of the present invention, the pore size of the first filter membrane 104 is larger than the pore size of the second filter membrane 105 , and the pore size of the second filter membrane 105 is larger than the pore size of the third filter membrane 106 .

[0104] Preferably, in the present technical solution, the first filter membrane 104 is preferably a DELP lipid adsorption filter membrane, the second filter membrane 105 is preferably a carbon material filter membrane, and the third filter membrane 106 is preferably a polyethersulfone filter membrane;

[0105] The pore size of the first filter membrane 104 is preferably 0.40 μm-0.55 μm, the pore size of the second filter membrane 105 is preferably 0.25 μm-0.40 μm, and the pore size of the third filter membrane 106 is preferably 0.2 μm.

[0106] Therefore, when the pore size of the first filter membrane 104, the pore size of the second filter membrane 105 and the pore size of the third filter membrane 106 are gradually reduced, lipid substances of various particle sizes in the patient's blood can be filtered out layer by layer as much as possible, so that the patient's blood has low viscosity after filtering and will be very clear and transparent without turbidity.

[0107] Furthermore, in the specific implementation, Figure 1 , Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, the present invention further comprises a liquid storage dish 20 for collecting blood, wherein a connection port 201 is provided on the upper portion of the liquid storage dish 20, and the connection port 201 is detachably connected to the liquid outlet 102.

[0108] Therefore, when the patient's blood needs to be stored and sampled for testing during use, the filtered patient's blood can be collected and stored through the liquid storage dish 20, making the present application flexible and convenient to use.

[0109] In addition, in this technical solution, Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, the liquid storage vessel 20 comprises a liquid storage cylinder 20a with an open upper portion and a cylinder cover 20b detachably covering the open upper portion of the liquid storage cylinder 20a;

[0110] The connecting port 201 is upwardly arranged in the middle of the top of the cylinder cover 20b, and a liquid taking port 202 is arranged in the middle of the left outer wall of the cylinder cover 20b to the left. The liquid taking port 202 is detachably covered with a sealing cap A203.

[0111] It should be noted here that the liquid storage dish 20 often requires a larger opening to facilitate the taking of the blood therein, so it is designed to include a liquid storage cylinder 20a with an open upper portion and a detachable cylinder cover 20b covering the open upper portion of the liquid storage cylinder 20a, and the connecting port 201 is provided upwardly from the middle of the top of the cylinder cover 20b. In this way, even if the use of the liquid storage dish 20 is convenient, when the collected filtered patient blood is not much and is only stored in the liquid storage cylinder 20a, the liquid storage cylinder 20a can be removed to facilitate the taking of the filtered patient blood collected therein.

[0112] Furthermore, the liquid storage dish 20 can also be used as a blood transfer container. By connecting a pipeline at the liquid collection port 202, the collected filtered patient blood can be returned to the patient's blood vessels. At this time, since the liquid collection port 202 is located in the middle of the left outer wall of the tube cover 20b, it is in a higher position. After the blood flows into the liquid storage dish 20, the heavier and larger lipid substances that may exist in it will be deposited at the bottom of the liquid storage dish 20 due to gravity, so that it can further purify the blood, so that the upper layer of clearer patient blood will be returned to the patient's blood vessels through the liquid collection port 202, so that the accumulation of blood clots in the patient's blood vessels can be better alleviated.

[0113] Furthermore, in the specific implementation, continue to compare Figure 2 , Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, a fourth filter membrane 204 having a pore size equal to that of the third filter membrane 106 is fixedly disposed on the left inner portion of the cylinder cover 20b which is inclined toward the lower left;

[0114] The upper end of the fourth filter membrane 204 is connected to the left middle part of the inner top surface of the tube cover 20b, and the lower end is connected to the lower part of the left inner wall of the tube cover 20b, so that the upper left part of the tube cover 20b forms a blood filtering cavity 205 connected to the liquid intake port 202.

[0115] Therefore, by setting the fourth filter membrane 204, lipid substances in the patient's blood can be further intercepted and filtered out, so that the blood flowing out of the liquid collection port 202 and returned to the patient's blood vessels will be clearer, and the fat content can be reduced to a lower level, so that the overall use effect of this application is better.

[0116] Again, in the specific implementation, Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, the present invention further comprises a detachable cap 30 covering the outside of the liquid inlet 101;

[0117] The right part of the cap 30 is connected upward with a blood guide tube 301 penetrating into the interior thereof, and the upper end of the blood guide tube 301 is provided with a connector 302 adapted to be connected with a blood extraction line for treating coronary heart disease.

[0118] In this way, by connecting the connector 302 to an external infusion line, the blood output from the patient's body can be easily guided into the filter cartridge 10 .

[0119] Furthermore, in a specific implementation, according to an embodiment of the present invention, the cap 30 is higher on the left and lower on the right, and the left portion of the cap 30 is upwardly connected to a drain head 303 that penetrates into the interior thereof, the drain head 303 has drain cotton 304 embedded therein, and the outside is detachably covered with a sealing cover B305.

[0120] It should be noted here that when the blood drawn from the patient's blood vessels flows into this application, if it is not emptied in time, it will make it difficult to flow in. Therefore, this application sets the emptying head 303 and embeds the emptying cotton 304 inside the emptying head 303, so that it can be emptied better, so that the blood drawn from the patient's blood vessels can flow into this application easily.

[0121] At the same time, since the structure of the cap 30 is higher on the left and lower on the right, after the present application is stably fixed on a desktop or the like, the height of the bottom of the emptying head 303 will be higher than the height of the bottom of the blood diversion tube 301, so that the patient's blood flowing into the present application through the blood diversion tube 301 is not easy to overflow through the emptying head 303, so that the present application is reliable to use, and at the same time, the emptying cotton 304 is provided for blocking, which can also better prevent the patient's blood from overflowing from the emptying head 303 and causing cross infection.

[0122] Therefore, in the present application, the tiny gap in the emptying cotton 304 has an emptying effect, and the emptying cotton 304 also has a function of absorbing residual blood. Therefore, it can be used for two purposes in one, and its functions can be fully utilized.

[0123] It should be added that in the specific implementation, Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, the present invention also includes a device for removing lipid substances in blood, which includes a fat removal pusher 50 containing a fat removal liquid 40;

[0124] Among them, a hollow connecting seat 107 is connected to the right at the upper middle part of the right side wall of the filter cartridge 10, and the hollow connecting seat 107 is connected to the inside thereof. The height of the left end of the hollow connecting seat 107 is flush with the height of the middle part of the lower bottom surface of the blood guide plate 103. The left end of the fat removal injector 50 is provided with a Luer connector 50a, and the Luer connector 50a is plugged and connected to the right end of the hollow connecting seat 107.

[0125] In this regard, it is clear that:

[0126] On the one hand, the present application sets up the degreasing injector 50, and when it is operated regularly or irregularly, it is convenient to push the degreasing liquid 40 stored therein into the filter cartridge 10 to remove the lipid substances in the patient's blood accumulated on the upper surface of the first filter membrane 104, the upper surface of the second filter membrane 105 and the upper surface of the third filter membrane 106, so as to avoid as much as possible the accumulation of a large amount of lipid substances in the patient's blood on the upper surface of the first filter membrane 104, the upper surface of the second filter membrane 105 and the upper surface of the third filter membrane 106, causing the entire surface to be blocked. In other words, through this optimized design, the overall use effect of the present application is better and the overall service life is longer.

[0127] On the other hand, since the height of the left end of the hollow connecting seat 107 is flush with the height of the middle part of the lower bottom surface of the blood guide plate 103, when the degreasing injector 50 is controlled regularly or irregularly to push the degreasing liquid 40 stored therein into the filter cartridge 10, the degreasing liquid 40 pushed out will be splashed to the middle part of the lower bottom surface of the blood guide plate 103 as much as possible in advance, and then, it will be reflected and refracted by the lower bottom surface of the blood guide plate 103, so that the degreasing liquid 40 pushed out from the degreasing injector 50 will be fully and as much as possible reflected and refracted to each position on the upper surface of the first filter membrane 104 in a divergent shape, so as to remove the lipid substances in the patient's blood accumulated at each position on the upper surface of the first filter membrane 104 as much as possible, so that the lipid substances in the patient's blood accumulated on the upper surface of the first filter membrane 104 can be removed quickly and efficiently.

[0128] Similarly, since the upper surface of the first filter membrane 104 can be sufficiently splashed with the degreasing liquid 40, the degreasing liquid 40 flowing down through the first filter membrane 104 can fully and as much as possible drip onto each position on the upper surface of the second filter membrane 105 and can also fully and as much as possible drip onto each position on the upper surface of the third filter membrane 106, so that the lipid substances in the patient's blood accumulated on the upper surface of the second filter membrane 105 and the lipid substances in the patient's blood accumulated on the upper surface of the third filter membrane 106 can also be removed quickly and efficiently.

[0129] Therefore, in the technical solution of the present application, the blood guide plate 103 provided therein is not only used to guide the patient's blood downward, but also used to provide reflection and refraction effects, so that the delipidating liquid 40 pushed out from the delipidating injector 50 can be fully reflected and refracted in a divergent shape to the upper surface of the first filter membrane 104 after being reflected and refracted by the lower bottom surface of the blood guide plate 103, so that the blood guide plate 103 provided is multi-functional and its function can be fully utilized.

[0130] Therefore, through the above-mentioned optimization design, the overall use effect of this application can be optimized.

[0131] It is further necessary to add that in the specific implementation, Figure 2 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, a one-way check valve 108 is provided inside the hollow connection seat 107 to allow the liquid medicine to enter the filter cartridge 10 from the outside to the inside.

[0132] Therefore, by providing the one-way check valve 108, it is possible to better prevent the patient's blood retained in the filter cartridge 10 from overflowing, thereby better preventing cross infection of blood.

[0133] Preferably, in this technical solution, Figure 6 As shown, according to one embodiment of the present invention, the one-way check valve 108 includes a hollow cylindrical valve body 1081 with openings at both left and right ends, a valve core 1082 and a pressure spring 1083;

[0134] The hollow cylindrical valve body 1081 has a liquid flow chamber 10811 in the middle along the left-right direction, the inner diameter of which is larger than the inner diameters of the openings at its left and right ends; the outer diameter of the valve core 1082 is smaller than the inner diameter of the liquid flow chamber 10811, and the right end surface periphery of the valve core 1082 is tightly against the right inner wall of the liquid flow chamber 10811, and the left end surface of the valve core 1082 is connected to the right end of the top pressure spring 1083; the left end of the top pressure spring 1083 is fixed to the left inner wall of the liquid flow chamber 10811;

[0135] When the valve core 1082 is pushed to the left by a certain force, the top pressure spring 1083 is compressed, the valve core 1082 moves leftward along the liquid medicine flow chamber 10811 , and the openings at both ends of the hollow cylindrical valve body 1081 are connected to the liquid medicine flow chamber 10811 .

[0136] From this, it can be understood that Figure 2As shown, when the degreasing injector 50 is manually operated to push the degreasing liquid 40 stored therein into the filter cartridge 10, the generated pushing force will push the valve core 1082 to the left. At this time, the top pressure spring 1083 will be compressed, and the valve core 1082 will move left along the liquid flow chamber 10811. In this way, the openings at the left and right ends of the hollow cylindrical valve body 1081 will be connected to the liquid flow chamber 10811, so as to push the degreasing liquid 40 into the filter cartridge 10 through the hollow connecting seat 107.

[0137] On the contrary, when the degreasing injector 50 is released, the valve core 1082 and the top pressure spring 1083 will automatically reset to the initial double position, and the periphery of the right end face of the valve core 1082 will continue to tightly abut against the right inner wall of the liquid flow chamber 10811 to seal the right end opening of the liquid flow chamber 10811, thereby effectively preventing the patient's blood retained in the filter cartridge 10 from overflowing through the hollow connecting seat 107.

[0138] Furthermore, during the use of the present application, the degreasing injector 50 may not be connected to the hollow connecting seat 107 in advance, and can be connected to the hollow connecting seat 107 at any time when needed, making the present application more flexible to use.

[0139] It should be further added that, in a specific implementation, according to the coronary heart disease treatment filter 1000 provided in an embodiment of the present invention, the connection port 201 is preferably threadedly connected to the liquid outlet 102; the cylinder cover 20b is preferably threadedly connected to the outside of the upper opening of the liquid storage cylinder 20a; the sealing cover A203 is preferably threadedly connected to the outside of the liquid extraction port 202; the cap 30 is preferably threadedly connected to the outside of the liquid inlet 101; the sealing cover B305 is preferably threadedly connected to the outside of the emptying head 303; the Luer connector 50a is preferably threadedly connected to the hollow connecting seat 107; the hollow cylindrical valve body 1081 of the one-way check valve 108 is preferably threadedly screwed into the hollow connecting seat 107.

[0140] Furthermore, in the preferred embodiment of the present application, Figure 7 and Figure 8 As shown, the degreasing pusher 50 includes a pusher cylinder 501, a piston push rod 502 and an anti-drop limiter 503;

[0141] Among them, the front end of the injection cylinder 501 is provided with the Luer connector 50a facing forward, the front upper part is provided with an injection head 5011 facing upward, and a detachable sealing cover C5012 is sealed on the outer sealing cover of the injection head 5011, and the rear part of the injection cylinder 501 is formed as an opening; the front end of the piston push rod 502 is inserted into the injection cylinder 501 through the rear opening of the injection cylinder 501, and the front end of the piston push rod 502 is provided with a sealing piston 502a whose outer wall tightly abuts against the inner wall of the injection cylinder 501, and the rear end of the piston push rod 502 is exposed to the rear opening of the injection cylinder 501; the anti-slip limiter 503 is fixedly arranged at the rear opening of the injection cylinder 501 to clamp and limit the sealing piston 502a to prevent it from slipping out backwards through the rear opening of the injection cylinder 501.

[0142] Specifically, in the present application, the anti-dropping limiter 503 preferably includes a sleeve 5031 with a sleeve opening at the front end and a gripping ear A5032 arranged around the outer periphery of the sleeve 5031;

[0143] Among them, the sleeve 5031 is threadedly sleeved on the rear opening of the injection cylinder 501, and the inner rear part of the sleeve 5031 is provided with a circle of annular inner edge 50311 which serves as a stop and limit. The inner diameter of the annular inner edge 50311 is slightly larger than the outer diameter of the piston push rod 502 and smaller than the outer diameter of the sealing piston 502a. The piston push rod 502 includes a rod body 5021 and a grip ear B5022 arranged at the rear of the rod body 5021. The grip ear B5022 is detachably connected to the rod body 5021.

[0144] From this, it can be clearly seen that:

[0145] On the one hand, before using the present application, it is not necessary to retain the degreasing liquid 40 in the injection barrel 501 in advance. After the Luer connector 50a of the degreasing injector 50 is connected to the hollow connecting seat 107, the sealing cap C5012 can be removed to add the degreasing liquid 40 to the injection barrel 501 through the injection head 5011. Alternatively, after the degreasing liquid 40 in the injection barrel 501 is used up, the sealing cap C5012 can be removed from time to time to add the degreasing liquid 40 to the injection barrel 501 again through the injection head 5011, so that the present application is more flexible to use.

[0146] On the other hand, when the handle B5022 and the rod body 5021 are removed in advance, it is convenient to put the sleeve 5031 on the outside of the rod body 5021 from back to front, and threadedly put it on the rear opening of the injection cylinder 501. Then, the handle B5022 can be connected to the rod body 5021, which facilitates the assembly of the degreasing injection device 50 described in the present application. At the same time, after the sealing piston 502a is retained in the injection cylinder 501, it is stopped by the annular inner edge 50311 arranged inwardly at the inner rear part of the sleeve 5031, so that it is not easy to slip out backwards to the outside of the rear part of the injection cylinder 501, making the present application very reliable to use.

[0147] In addition, in the preferred embodiment of the present application, the outer wall of the filter cartridge 10 is provided with capacity scales 109 from bottom to top, so that medical personnel can calculate the amount of blood drawn from the patient's blood vessels through the scales.

[0148] Other embodiments and the like are not described here by way of example.

[0149] In summary, the coronary heart disease treatment filter 1000 provided by the present application, in a specific implementation, the blood guide plate 103 is arranged to be inclined toward the lower left side of the filter cartridge 10, so as to guide the blood downward, so as to avoid the blood from splashing upward inside the filter cartridge 10 as much as possible. The blood transported to the filter cartridge 10 is filtered through the first filter membrane 104, the second filter membrane 105 and the third filter membrane 106 for three-stage filtration, so that the lipid substances in the patient's blood can be better reduced, so that when the processed blood is subsequently returned to the patient's blood vessels, the blood contains less fat, which can better alleviate the accumulation of blood clots in the patient's blood vessels.

[0150] Furthermore, compared to the conventional method of setting the filter membrane horizontally, the present application sets the first filter membrane 104, the second filter membrane 105 and the third filter membrane 106 to be tilted toward the lower right side of the filter cartridge 10. In this way, the patient's blood transported into the filter cartridge 10 can flow over a larger area on its upper surface, so that per unit volume of the filter cartridge 10, the present application has an excellent filtering effect on the patient's blood, and the filtered lipid substances will also flow to the lower right part of the first filter membrane 104, the lower right part of the second filter membrane 105 and the lower right part of the third filter membrane 106 due to gravity, so that the upper left part of the first filter membrane 104, the upper left part of the second filter membrane 105 and the upper left part of the third filter membrane 106 are not easily blocked by the filtered lipid substances, so that per unit time, the present application has a long service life and can greatly reduce the number and frequency of replacements during use.

[0151] In addition, by providing the fourth filter membrane 204, lipid substances in the patient's blood can be further intercepted and filtered out, so that the blood flowing out of the liquid collection port 202 and returned to the patient's blood vessels will be clearer, and the fat content can be reduced to a lower level, so that the overall use effect of this application is better.

[0152] Furthermore, the present application provides the degreasing injector 50, which can push the degreasing liquid 40 stored therein into the filter cartridge 10 when it is operated regularly or irregularly, so as to remove the lipid substances in the patient's blood accumulated on the upper surface of the first filter membrane 104, the upper surface of the second filter membrane 105 and the upper surface of the third filter membrane 106, so as to avoid as much as possible the accumulation of a large amount of lipid substances in the patient's blood on the upper surface of the first filter membrane 104, the upper surface of the second filter membrane 105 and the upper surface of the third filter membrane 106, causing the entire surface to be blocked. In other words, through this optimized design, the overall use effect of the present application is better and the overall service life is longer.

[0153] Again, since the height of the left end of the hollow connecting seat 107 is flush with the height of the middle part of the lower bottom surface of the blood guide plate 103, when the degreasing injector 50 is controlled regularly or irregularly to push the degreasing liquid 40 stored therein into the filter cartridge 10, the squeezed degreasing liquid 40 will be splashed to the middle part of the lower bottom surface of the blood guide plate 103 as much as possible in advance, and then, it will be reflected and refracted by the lower bottom surface of the blood guide plate 103, so that the degreasing liquid 40 pushed out from the degreasing injector 50 will be fully and as much as possible reflected and refracted in a divergent shape to each position on the upper surface of the first filter membrane 104, so as to remove the lipid substances in the patient's blood accumulated at each position on the upper surface of the first filter membrane 104 as much as possible, so that the lipid substances in the patient's blood accumulated on the upper surface of the first filter membrane 104 can be removed quickly and efficiently.

[0154] Similarly, since the upper surface of the first filter membrane 104 can be sufficiently splashed with the degreasing liquid 40, the degreasing liquid 40 flowing down through the first filter membrane 104 can fully and as much as possible drip onto each position on the upper surface of the second filter membrane 105 and can also fully and as much as possible drip onto each position on the upper surface of the third filter membrane 106, so that the lipid substances in the patient's blood accumulated on the upper surface of the second filter membrane 105 and the lipid substances in the patient's blood accumulated on the upper surface of the third filter membrane 106 can also be removed quickly and efficiently.

[0155] Furthermore, by providing the one-way check valve 108, the patient's blood retained in the filter cartridge 10 can be better prevented from overflowing, thereby better preventing cross infection of blood.

[0156] Furthermore, the coronary heart disease treatment filter 1000 provided in the present application is indeed extremely practical and has excellent use effects, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
