Description

Technical Field

[0001] This invention relates to the field of cryoprecipitate infusion technology, and more particularly to a cryoprecipitate intervention device for the treatment of patients with acute ischemic stroke who have undergone thrombolysis and hemorrhage. Background Technology

[0002] Acute ischemic stroke is a disease that causes brain tissue necrosis due to sudden narrowing or blockage of cerebral blood vessels. If the patient seeks medical attention promptly and the symptoms are not too severe, the thrombus can be dissolved through intravenous thrombolysis. After the blood vessels are reopened, the brain tissue that was previously deprived of blood supply can regain its blood supply. Post-thrombolysis hemorrhage is a common complication in the treatment of acute ischemic stroke, mainly because thrombolytic drugs can cause damage to blood vessels and rupture. If the bleeding is small, conservative drug treatment can be used, such as intravenous infusion of cryoprecipitate or fresh plasma to promote blood clotting. Prothrombin complex concentrate can also be infused to promote coagulation. If there is a large area of ​​bleeding, craniotomy is required to remove the hematoma.

[0003] Cryoprecipitate infusion is a treatment method that improves coagulation function and reduces or prevents bleeding by intravenously injecting cryoprecipitate. Cryoprecipitate is a blood product formed after human plasma has been processed. Compared with plasma, the concentration and density of various coagulation factors in cryoprecipitate are significantly increased.

[0004] After cryoprecipitate is rapidly melted, it is infused at the fastest rate that the patient can tolerate. Each bag of cryoprecipitate contains only 25-30ml. When patients require large infusions, the transfusion nurse cannot leave the bedside and must change the blood bag at any time, which causes a shortage of medical personnel and wastes manpower. Therefore, a cryoprecipitate intervention device for the treatment of patients with acute ischemic stroke and thrombolysis with blood bag changing function was developed. Summary of the Invention

[0005] To overcome the shortcomings of blood transfusion nurses being unable to leave the patient's bedside and needing to change blood bags frequently, which leads to a shortage of medical personnel and waste of manpower, this invention provides a combined cryoprecipitate intervention device for the treatment of acute ischemic stroke patients with thrombolytic hemorrhage and blood bag changing function.

Detailed Implementation

[0038] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0039] Example 1: A device for treating acute ischemic stroke patients with thrombolysis and hemorrhage combined with cryoprecipitate intervention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the device includes a base 1, a bracket 111, a placement platform 112, a cross-shaped rotating box 11, and covers 12. The cross-shaped rotating box 11 is rotatably connected to the base 1. Circular through holes are opened on the four sides (front, back, left, and right) of the bottom wall of the cross-shaped rotating box 11. There are four covers 12, each rotatably connected to the four sides (front, back, left, and right) of the upper side of the cross-shaped rotating box 11. The bracket 111 is connected to the base 1, and the placement platform 112 is connected to the upper left part of the base 1. The device also includes an infusion tube 18, an infusion hose 181, a fixing plate 182, a first spring 19, a limiting frame 110, a drive assembly, and a fixing... The mechanism includes an infusion tube 18 slidably connected to the upper front side of the support 111, an infusion tubing 181 connected to the bottom of the infusion tube 18, the needle end of the infusion tubing 181 placed on the placement platform 112, a fixing plate 182 connected to the lower part of the infusion tube 18, a first spring 19 connected between the fixing plate 182 and the support 111, the first spring 19 wound around the infusion tube 18, a limiting frame 110 connected to the upper part of the infusion tube 18, a drive assembly provided at the lower part of the cross-shaped rotating box 11, and a fixing mechanism provided inside the cross-shaped rotating box 11, which can be used to clamp and fix the blood bag.

[0040] like Figure 4 and Figure 5 As shown, the drive assembly includes a motor 13, a first gear 14, a rotating drum 15, a torsion spring 16, and a pusher 17. The rotating drum 15 is rotatably connected to the bracket 111. The cross-shaped rotating box 11 passes through the rotating drum 15. A first gear 14 is connected to the lower part of the rotating drum 15. The motor 13 is mounted on the base 1. The output shaft of the motor 13 is connected to another first gear 14 through a coupling. The two first gears 14 mesh with each other. The torsion spring 16 is connected between the top of the rotating drum 15 and the cross-shaped rotating box 11. The torsion spring 16 is wound around the cross-shaped rotating box 11. There are four pushers 17. The pushers 17 are evenly connected to the upper part of the rotating drum 15 along the circumference. The pushers 17 are pressed and engaged with the fixed plate 182.

[0041] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing mechanism includes a first fixing rod 2, a second spring 21, a first clamping plate 22, a weight sensor 26, and a control component. There are four first fixing rods 2, which are respectively connected to the front, back, left, and right cavities of the cross rotating box 11. There are eight first clamping plates 22, which are slidably connected to the first fixing rods 2. A second spring 21 is connected between two adjacent first clamping plates 22 and is wound around the adjacent first fixing rod 2. Weight sensors 26 are installed on the front, back, left, and right sides of the bottom wall of the cross rotating box 11. Control components are also provided on the front, back, left, and right sides of the bottom wall of the cross rotating box 11.

[0042] like Figure 6and Figure 8 As shown, the control assembly includes a first telescopic rod 23, a third spring 24, and a wedge frame 25. There are four first telescopic rods 23, which are respectively connected to the front, back, left, and right sides of the bottom wall of the cross-shaped rotating box 11. There are four wedge frames 25, which are respectively connected to the telescopic ends of the first telescopic rods 23. A third spring 24 is connected between the bottom of the wedge frame 25 and the adjacent first telescopic rod 23. The third spring 24 is wound around the telescopic end of the first telescopic rod 23. The cover 12 is pressed and engaged with the adjacent wedge frame 25.

[0043] Initially, the third spring 24 is in a deformed state, and the cover 12 is pressed against the wedge frame 25. When using this device, medical personnel first pull down the fixing plate 182, causing the needle on the infusion tubing 18 to exit from the cross-shaped rotating box 11. The fixing plate 182 will then move the infusion tubing 18 and the limiting frame 110 downwards, causing the first spring 19 to deform. Next, the cover 12 is flipped open sequentially. Under the elastic action of the third spring 24, the wedge frame 25 moves upwards, and the first telescopic rod 23 extends upwards. The upward movement of the wedge frame 25 will compress the first clamping plate 22, causing... The first clamp 22 separates outwards, the second spring 21 deforms, and the four thawed blood bags are placed on the weight sensors 26 in the four chambers of the cross-shaped rotating box 11, with the opening of the blood bags facing down into the circular through holes. Then, the lids 12 are flipped and closed in sequence, pressing the lids 12 onto the wedge-shaped frame 25, causing the wedge-shaped frame 25 to move downwards. The first telescopic rod 23 retracts downwards, and the third spring 24 returns to its deformed state. At the same time, under the elastic action of the second spring 21, the first clamp 22 moves inwards to clamp the blood bags. At this point, the blood bags have been placed.

[0044] Medical staff can loosen the fixing plate 182. Under the elastic action of the first spring 19, the infusion tube 18 will drive the limiting frame 110 to move upward and reset. The needle on the infusion tube 18 will pierce the opening of the blood bag. Then, the medical staff will pinch the needle on the infusion tubing 181 and insert it into the patient's vein. The cryoprecipitate in the blood bag will enter the patient's body through the infusion tube 18 and the infusion tubing 181 to realize cryoprecipitate infusion.

[0045] As the cryoprecipitate in the blood bag is rapidly discharged, the weight of the blood bag on the weight sensor 26 decreases. The weight sensor 26 then controls the output shaft of the motor 13 to drive the first gear 14 to rotate, thereby causing the rotating drum 15 and the pusher 17 to rotate. The torsion spring 16 is twisted. When the pusher 17 rotates to contact the fixed plate 182, the pusher 17 will press the fixed plate 182 downward. The fixed plate 182 will then cause the infusion tubing 18 and the limiting frame 110 to move downward. The limiting frame 110 will no longer jam the cross-shaped rotating box 11, and the first spring 19 will deform. Then, under the action of the torsion spring 16, the cross-shaped rotating box 11 will rotate 90 degrees clockwise. At the same time, when the pusher 17 separates from the fixing plate 182, under the elastic action of the first spring 19, the infusion tube 18 will drive the limiting frame 110 to move upward. The limiting frame 110 will continue to hold the cross-shaped rotating box 11, and the infusion tube 18 will continue to puncture the opening of the blood bag to continue infusion to the patient. In this way, when all the cryoprecipitate in the four blood bags of the fixing frame has been infused, the medical staff can pull the needle of the infusion tubing 181 out of the patient's body.

[0046] In summary, the first clamp 22 automatically opens and closes through the cooperation of the cover 12 and the wedge frame 25, which facilitates the clamping and fixing of the blood bag. Then, the blood bag is automatically replaced through the cooperation of the pusher 17 and the fixing plate 182, which avoids the need for medical staff to leave the bed during infusion, thus avoiding the waste of medical staff and improving the ease of operation of the device.

[0047] Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, it also includes a protective mechanism that can be used to wrap the needle on the infusion tube 18. The protective mechanism is set on the limiting frame 110. The protective mechanism includes a rotating plate 3, a rotating shaft 31, a second gear 32, a rack frame 33, a second telescopic rod 34, and an elastic component. There are two rotating shafts 31, which are rotatably connected to the left and right sides of the lower side of the limiting frame 110. There are two rotating plates 3, which are connected to the rotating shafts 31. There are two second gears 32, which are connected to the front of the rotating shafts 31. The second telescopic rod 34 is connected to the lower part of the limiting frame 110. The telescopic end of the second telescopic rod 34 is connected to the rack frame 33. The rack frame 33 meshes with the second gear 32. An elastic component is provided on the rack frame 33.

[0048] like Figure 9 As shown, the elastic component includes a slide rod 35 and a fourth spring 36. The slide rod 35 is slidably connected to the upper part of the rack frame 33, and the fourth spring 36 is connected between the lower part of the slide rod 35 and the rack frame 33. The fourth spring 36 is wound around the slide rod 35, and the cross rotating box 11 is pressed and engaged with the slide rod 35.

[0049] Initially, the fourth spring 36 is in a stretched state. When the infusion tubing 18 and the limiting frame 110 move downwards, the limiting frame 110 will drive the second telescopic rod 34, rack and pinion 33, and slide rod 35 to move downwards. When the slide rod 35 moves downwards and separates from the cross-shaped rotating box 11, under the elastic action of the fourth spring 36, the slide rod 35 will move upwards, thereby driving the rotating plate 3 to rotate inwards through the second gear 32 and the rotating shaft 31. The rotating plate 3 will wrap around the needle on the infusion tubing 18. When the infusion tubing 18 and the limiting frame 11... When the slide bar 35 moves upward, it is blocked by the cross-shaped rotating box 11, causing the slide bar 35 to move downward and the fourth spring 36 to be in a stretched state. At the same time, through the cooperation of the rack frame 33 and the second gear 32, the rotating plate 3 flips outward and opens, so that the rotating plate 3 no longer covers the needle on the infusion tube 18. In summary, through the cooperation of the cross-shaped rotating box 11 and the slide bar 35, the rotating plate 3 can cover the needle of the infusion tube 18 when changing blood bags, so that the needle can be kept clean during the blood bag change and the safety of cryoprecipitate infusion can be improved.

[0050] like Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, it also includes a locking mechanism, which can be used to clamp the infusion tubing 181 when the blood bag is changed. The locking mechanism is set on the fixing plate 182 and includes a fixing frame 4, a second clamping plate 41, a fifth spring 42 and a fixing frame 43. The fixing frame 4 is connected to the bottom of the fixing plate 182. There are two second clamping plates 41, which are slidably connected to the left and right sides of the lower part of the fixing frame 4. The fifth spring 42 is connected between the second clamping plates 41 and is wrapped around the fixing frame 4. The fixing frame 43 is connected to the upper front side of the bracket 111. The second clamping plate 41 and the fixing frame 43 are pressed together. The fixing frame 43 is set with a wider top and narrower bottom.

[0051] When the pusher 17 presses the fixing plate 182 downward, the fixing plate 182 will drive the fixing frame 4 and the second clamping plate 41 to move downward. The second clamping plate 41 will be held against by the fixing frame 43, causing the second clamping plate 41 to move inward to clamp the infusion tubing 181. The fifth spring 42 will deform. Conversely, when the pusher 17 separates from the fixing plate 182, the fixing plate 182 will drive the fixing frame 4 and the second clamping plate 41 to move upward. Under the elastic action of the fifth spring 42, the second clamping plate 41 will move outward to release the infusion tubing 181. In summary, the second clamping plate 41 can automatically clamp the infusion tubing 181 when changing blood bags, preventing the blood in the infusion tube 18 from continuing to be infused during the blood bag change, which could cause air to enter the infusion tube and form an embolism, thus improving the safety of the infusion.

[0052] like Figure 2 , Figure 13 and Figure 14 As shown, it also includes a sealing mechanism, which can be used to keep the uninjected blood bag warm. The sealing mechanism is set at the bottom of the cross-shaped rotating box 11. The sealing mechanism includes a third telescopic rod 5, a baffle 51, a wedge plate 52 and a sixth spring 53. There are four third telescopic rods 5, which are respectively connected to the front, back, left and right sides of the bottom wall of the cross-shaped rotating box 11. There are four baffles 51, which are respectively connected to the telescopic ends of the third telescopic rods 5. There are four wedge plates 52, which are respectively connected to the baffles 51. A sixth spring 53 is connected between the wedge plate 52 and the adjacent third telescopic rod 5. The sixth spring 53 is wound around the telescopic end of the adjacent third telescopic rod 5. The elastic coefficient of the fourth spring 36 is much greater than that of the sixth spring 53. The sliding rod 35 is in a pressing fit with the wedge plate 52.

[0053] Initially, baffle 51 seals the circular through-hole of the cross-shaped rotating box 11, keeping the blood bag in a warm state within the box to ensure the bioactivity of cryoprecipitate. When the infusion tubing 18 and the limiting frame 110 move upward, they drive the sliding rod 35 upward. The sliding rod 35 is held in place by the wedge plate 52. Since the elastic coefficient of the fourth spring 36 is much greater than that of the sixth spring 53, the sliding rod 35 pushes the wedge plate 52 to the right, thereby moving baffle 51 to the right to open the circular through-hole. The third telescopic rod 5 retracts to the right, and the sixth spring 53 releases... Conversely, when the infusion tubing 18 and the limiting frame 110 move downwards, the sliding rod 35 will move downwards. When the sliding rod 35 separates from the wedge plate 52, under the elastic action of the sixth spring 53, the wedge plate 52 will drive the baffle 51 to move to the left and reset. The third telescopic rod 5 extends to the left, and the baffle 51 seals the circular through hole of the cross-shaped rotating box 11. In summary, through the cooperation of the wedge plate 52 and the sliding rod 35, the baffle 51 can be automatically opened when the blood bag is changed, avoiding a large change in the temperature of the blood bag before the change, and improving the effect of cryoprecipitate infusion.

[0054] like Figure 1 and Figure 15 As shown, it also includes a positioning mechanism, which is used to ensure that the angle of rotation of the cross-shaped rotating box 11 is the same each time. The positioning mechanism is set on the base 1 and includes a second fixed rod 6, a fourth telescopic rod 61, a seventh spring 62 and a limiting plate 63. There are four second fixed rods 6, which are evenly connected to the lower part of the cross-shaped rotating box 11 along the circumference. There are also four fourth telescopic rods 61, which are evenly connected to the upper side of the base 1 along the circumference. The telescopic end of the fourth telescopic rod 61 is connected to the limiting plate 63. The bottom of the limiting plate 63 is connected to the adjacent fourth telescopic rod 61 with a seventh spring 62. The seventh spring 62 is wrapped around the telescopic end of the adjacent fourth telescopic rod 61. The second fixed rod 6 and the limiting plate 63 are in a pressing fit.

[0055] When the cross-shaped rotating box 11 rotates clockwise, it drives the second fixed rod 6 to rotate. When the second fixed rod 6 contacts the limiting plate 63, it presses the limiting plate 63 down, causing the fourth telescopic rod 61 to retract downwards. The seventh spring 62 deforms. When the second fixed rod 6 separates from the limiting plate 63, under the elastic action of the seventh spring 62, the limiting plate 63 moves upwards to lock the second fixed rod 6, and the fourth telescopic rod 61 extends upwards. In summary, through the cooperation of the second fixed rod 6 and the limiting plate 63, the cross-shaped rotating box 11 rotates at the same angle each time, thereby achieving precise blood bag replacement and improving the ease of operation of the device.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
