Description

Technical Field

[0001] The present application relates to the technical field of blood transfusion devices, and in particular to a blood transfusion device for real-time monitoring of multiple parameters and constant temperature regulation. Background Art

[0002] Blood transfusion is a core means in modern medicine to treat critical situations such as severe trauma, massive bleeding, anemia, and blood loss during surgery.

[0003] Stored blood needs to be refrigerated at 4±2℃ to maintain the activity of its components. However, direct transfusion of refrigerated blood will cause the patient's body temperature to drop suddenly, leading to hypothermia, which in turn may induce arrhythmia, coagulation dysfunction, or even cardiac arrest. Therefore, the blood needs to be heated before transfusion.

[0004] In the prior art, blood thermoregulation is usually achieved by using a heating jacket wrapped around the blood transfusion tube (i.e., the blood transfusion tube is sequentially pressed into the heating jacket along its length direction to achieve the covering of the blood transfusion tube by the heating jacket), or by providing an S-shaped placement groove on the heating plate, and the blood transfusion tube needs to be pressed and inserted along the shape of the placement groove to heat it.

[0005] The above-mentioned blood transfusion heating has the following problems: on the one hand, in the rescue scenario, the heating operation of the transfusion tube is relatively cumbersome, which affects the rescue timeliness; on the other hand, the blood monitoring function of the transfusion is single (usually only a temperature sensor is installed near the patient's transfusion end), lacks integrated monitoring of blood quality, and usually requires a secondary manual visual inspection.

[0034] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0035] The following describes the blood transfusion device for real-time monitoring of multiple parameters and constant temperature regulation according to an embodiment of the present application with reference to the accompanying drawings.

[0036] like Figure 1 As shown, the blood transfusion device for real-time multi-parameter monitoring and constant temperature regulation according to an embodiment of the present application may include a stand 100 , a multi-parameter monitoring structure 200 and a heating assembly 300 .

[0037] The multi-parameter monitoring structure 200 is set on the pole 100, the blood transfusion bag 410 is hung on the top of the pole 100, and the blood transfusion tube 420 is buckled on the monitoring end of the multi-parameter monitoring structure 200 and extends downward.

[0038] The side of the blood transfusion tube 420 close to the patient is arranged in the heating assembly 300. Figure 2 and Figure 4 As shown, the heating assembly 300 includes a box body 310 , a box cover 320 , a guiding device 330 , a winding device 340 and a heating plate 350 .

[0039] Among them, the box cover 320 can be translated and set on the top of the box body 310, two guiding devices 330 with opposite driving directions are respectively set on both sides of the box body 310, and the winding device 340 can be rotatably set in the box body 310. The blood transfusion tube 420 is pressed on the retractable and rewinding ends of the two guiding devices 330 and the winding end of the winding device 340. The two heating plates 350 are arranged opposite to each other up and down, among which the lower heating plate 350 is set below the winding end of the winding device 340, and the upper heating plate 350 is set in the box cover 320.

[0040] The driving ends of the guiding device 330 and the winding device 340 are respectively connected to the box cover 320, so that when the box cover 320 is pushed from the back to the front of the box body 310, the two guiding devices 330 gather the blood transfer tube 420 into the box body 310, while the winding device 340 winds the blood transfer tube 420 and heats the wound blood transfer tube 420 through the heating plate 350.

[0041] It should be noted that, in order to adjust the heating temperature of the blood transfusion tube 420, the present application can adopt the same method as the prior art (i.e., a temperature sensor is provided at the blood transfusion end, and the blood transfusion temperature of the blood transfusion tube 420 is monitored by the temperature sensor, so as to facilitate the regulation of the heating temperature of the heating plate 350).

[0042] Specifically, when medical staff perform emergency blood transfusion on patients, they first hang the blood transfusion bag 410 on the top of the pole 100, and then snap the blood transfusion tube 420 onto the monitoring end of the multi-parameter monitoring structure 200 to monitor multiple parameters of the blood transfusion.

[0043] Then, the subsequent blood transfusion tube 420 is pressed into the guiding devices 330 on both sides of the box 310 , and the blood transfusion tube 420 located in the box 310 is pressed onto the winding end of the winding device 340 .

[0044] The medical staff then pushes the box cover 320. The movement of the box cover 320 drives the two guide devices to rotate toward each other, thereby gathering the blood transfusion tube 420 into the box body 310. At the same time, the movement of the box cover 320 drives the winding end of the winding device 340 to rotate, winding the blood transfusion tube 420 in the box body 310 into a disc shape. The top heating plate 350 moves with the box cover 320 to the top of the rolled blood transfusion tube 420, and heats the blood transfusion tube 420 together with the heating plate 350 located below the winding end of the winding device 340.

[0045] During the blood transfusion process, the monitoring end of the multi-parameter monitoring structure 200 monitors the blood transfusion parameters in real time and issues an alarm when an abnormality occurs.

[0046] It should be noted that when the blood transfusion is completed and the medical staff pushes open the box cover 320 again, the reverse movement of the box cover 320 drives the winding device 340 to rotate in the opposite direction to release the wound blood transfusion tube 420. At the same time, the reverse movement of the box cover 320 drives the two guiding devices 330 to rotate in opposite directions, guiding the blood transfusion tube 420 located in the box body 310 outward, thereby avoiding tangling when releasing the wound blood transfusion tube 420.

[0047] In one embodiment of the present application, the multi-parameter monitoring structure 200 includes a main control panel, a drip rate sensor, an ultrasonic bubble detector, and an optical sensor.

[0048] Among them, the main control panel is fixed to the vertical pole 100 through a pipe clamp, the ultrasonic bubble detector and the optical sensor are respectively clamped on the blood transfusion tube 420 and electrically connected to the main control panel respectively, and the drip rate sensor is arranged at the drip bucket 430 and electrically connected to the main control panel.

[0049] The main control panel is equipped with a built-in alarm to sound an alarm when the monitoring data of the drip rate sensor, ultrasonic bubble detector or optical sensor is not within the preset threshold range.

[0050] It should be noted that the ultrasonic bubble detector can use a clamp-type ultrasonic sensor. After the ultrasonic wave penetrates the wall of the blood transfusion tube 420, it propagates stably when encountering the uniform medium of blood. The presence of bubbles is determined by the sudden change in the signal amplitude at the receiving end, so as to monitor the bubbles in the blood transfusion tube 420 and avoid air embolism. The optical sensor can use dual-wavelength infrared light to pass through the blood and analyze the difference in absorbance to identify the hemolysis or coagulation state of the blood. The drip rate sensor can use a Hall element to detect the falling frequency of blood in the drip bucket 430 and convert it into flow rate.

[0051] It is understandable that, when a temperature sensor is provided at the blood transfusion end of the blood transfusion tube, the temperature sensor may be electrically connected to the main control panel.

[0052] In one embodiment of the present application, Figures 5 to 7 As shown, the winding device 340 includes a winding head structure 341 , a connecting shaft 342 , a first gear 343 , a limiting sleeve 344 , and a first rack 345 .

[0053] The connecting shaft 342 is rotatably disposed within the housing 310, the first gear 343 is disposed on the connecting shaft 342, the limiting sleeve 344 is disposed within the housing 310 and communicates with the back of the housing 310, and the first rack 345 is disposed on the housing cover 320 via a guide rod. When the housing cover 320 moves toward the housing 310, the first rack 345 is embedded in and slidably disposed within the limiting sleeve 344 and meshes with the first gear 343. The winding head structure 341 is disposed on top of the connecting shaft 342.

[0054] The lower heating plate 350 is disposed below the winding head structure 341 and is fixed in the box body 310 .

[0055] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 8 As shown, the winding head structure 341 includes a rotating head 3411 coaxially connected to the connecting shaft 342, and a baffle 3414 is circumferentially sleeved on the outer wall of the rotating head 3411. A first slot 3412 is provided on one side of the rotating head 3411 from the top downward to the baffle 3414, and a second slot 3413 is provided on the other side of the rotating head 3411 from the top downward to the bottom; a pipe through groove 3415 is provided on the baffle 3414 and is connected to the second slot 3413.

[0056] It should be noted that before winding the blood transfusion tube 420, the medical staff presses the blood transfusion tube 420 in the box 310 into the first slot 3412 and the second slot 3413 in sequence. Due to the height difference between the bottom positions of the first slot 3412 and the second slot 3413, and due to the shielding effect of the baffle 3414, when the rotating head 3411 rotates, the blood transfusion tube 420 located in the first slot 3412 is wound above the baffle 3414, and the blood transfusion tube 420 located in the second slot 3413 is wound below the baffle 3414, forming a double-layer winding. The blood transfusion tube 420 wound below the baffle 3414 is heated by the lower heating plate 350, and the upper heating plate 350 heats the blood transfusion tube 420 wound above the baffle 3414.

[0057] When the medical staff pushes the box cover 320, the box cover 320 drives the first rack 345 to move in the limiting sleeve 344 and drives the first gear 343 to rotate, so that the connecting shaft 342 drives the rotating head 3411 to rotate, thereby achieving double-layer winding of the blood transfusion tube 420. As the box cover 320 is pushed, the heating plate 350 provided on the box cover 320 moves above the wound blood transfusion tube 420 and heats the blood transfusion tube 420 together with the heating plate 350 located below.

[0058] It should be noted that in order to prevent the blood transfusion tube 420 from bouncing up after being pressed into the first and second slots 3412 and 3413, the first and second slots 3412 and 3413 are provided with a tapered groove width (i.e., the groove width gradually decreases from top to bottom) to achieve squeezing of the blood transfusion tube 420 after it is inserted.

[0059] As a possible situation, arc transition is provided between the first clamping groove 3412 and the second clamping groove 3413 to avoid the blood transfusion blood tube 420 from bending and thus affecting the blood transfusion flow rate.

[0060] In one embodiment of the present application, Figure 3 As shown, placement slots 311 are respectively opened on both sides of the box body 310, and each guiding device 330 is respectively arranged at the corresponding placement slot 311.

[0061] like Figures 9 to 11 As shown, each guiding device 330 includes a driving structure 331 , an elastic roller structure 332 , a squeezing roller structure 333 and a trigger pressing structure 334 .

[0062] Mounting frames 301 are respectively provided on both sides of the placement slot 311 , and the rotating ends of the driving structure 331 and the elastic roller structure 332 are relatively provided on the two mounting frames 301 , wherein the driving end of the driving structure 331 is connected to the box cover 320 .

[0063] The squeezing roller structure 333 is elastically arranged below the driving structure 331 and the elastic roller structure 332, and the two ends of the squeezing roller structure 333 are respectively vertically slidably arranged on the two mounting frames 301, forming a squeezing area for the blood transfer tube 420 through the driving structure 331, the elastic roller structure 332 and the squeezing roller structure 333.

[0064] When the blood transfer tube 420 is pressed into the guide device 330, the blood transfer tube 420 squeezes the elastic roller structure 332, forcing the elastic roller structure 332 to move laterally. After the blood transfer tube 420 moves into the squeezing area, the elastic roller structure 332 is reset.

[0065] The downward pressing end of the trigger downward pressing structure 334 is connected to the squeezing roller structure 333, and the triggering end of the trigger downward pressing structure 334 is connected to the box cover 320. When the box cover 320 moves toward the box body 310, the rotating end of the driving structure 331 drives the blood transfusion tube 420 to move, and when the box cover 320 moves to just above the box body 310, the triggering end of the trigger downward pressing structure 334 abuts against the downward pressing end of the trigger downward pressing structure 334, thereby driving the squeezing roller structure 333 to move downward, canceling the squeezing of the blood transfusion tube 420 by the squeezing roller structure 333, and ensuring normal blood transfusion.

[0066] A channel is provided on the back of the box body 310 for the driving end of the driving structure 331 and the triggering end of the trigger pressing structure 334 to pass through.

[0067] It should be noted that when the blood transfer tube 420 is pressed into the guiding device 330, the squeezing elastic roller structure 332 moves laterally to make way for the channel, allowing the blood transfer tube 420 to enter the squeezing area. Due to the elastic squeezing of the squeezing roller structure 333, the rotating end of the driving structure 331 abuts against the outer wall of the blood transfer tube 420.

[0068] When the box cover 320 is closed (i.e., when the box cover 320 moves toward the front of the box body 310), the box cover 320 pushes the driving end of the driving structure 331, the rotating end of the driving structure 331 rotates, and the guiding devices 330 on both sides of the box body 310 rotate relative to each other, gathering the blood transfer tubes 420 on both sides of the box body 310 into the box body 310.

[0069] When the box cover 320 is opened (i.e., when the box cover 320 moves toward the back of the box body 310), the box cover 320 pushes the driving end of the driving structure 331, the rotating end of the driving structure 331 rotates, and the guiding devices 330 on both sides of the box body 310 rotate in opposite directions, pulling the blood transfusion tube 420 in the box body 310 outward.

[0070] To clearly illustrate the previous embodiment, in one embodiment of the present application, the driving structure 331 includes a second rack 3311 , a second gear 3312 , a meshing bevel gear set 3313 and a rotating roller 3314 .

[0071] Among them, the second rack 3311 is set on the bottom side of the box cover 320, the second gear 3312 can be rotatably set on the side wall of the box body 310, and the rotating roller 3314 can be rotatably set on the corresponding mounting frame 301 and is connected to the second gear 3312 through the meshing bevel gear set 3313.

[0072] When the box cover 320 moves toward the front of the box body 310 , the second rack 3311 meshes with the second gear 3312 , and drives the rotating roller 3314 to rotate through the meshing bevel gear set 3313 .

[0073] It should be noted that the meshing bevel gear set 3313 includes two meshing bevel gears, one of which is coaxial with the second gear 3312 , and the other is coaxial with the rotating roller 3314 .

[0074] It is understandable that by mirroring the bevel gear sets on both sides of the box body 310, the guiding directions of the guiding devices 330 on both sides of the box body 310 can be opposite, thereby achieving the operations of gathering inward and pulling outward the blood transfer tube 420.

[0075] To clearly illustrate the previous embodiment, in one embodiment of the present application, the elastic roller structure 332 includes a moving rod 3321 , a transverse elastic member 3322 and a roller head 3323 .

[0076] Among them, the moving rod 3321 can be laterally moved and set on the corresponding mounting frame 301, and a rotatable roller head 3323 is set at one end of the moving rod 3321, and the roller head 3323 is set opposite to the rotating end of the driving structure 331, and the other end of the moving rod 3321 is provided with a transverse elastic member 3322 that can drive the moving rod 3321 to reset.

[0077] It should be noted that the transverse elastic member 3322 can be a tension spring, and the two ends of the tension spring are respectively fixed to the ends of the mounting frame 301 and the movable rod 3321. When the blood transfer tube 420 is pressed downward, the roller head 3323 can be squeezed, causing the movable rod 3321 to move outward, thereby stretching the tension spring. After the blood transfer tube 420 enters the squeezing area, the movable rod 3321 drives the roller head 3323 to reset due to the reset action of the pull rope spring.

[0078] To clearly illustrate the previous embodiment, in one embodiment of the present application, the squeezing roller structure 333 includes a squeezing roller 3331 , a slider 3332 and a vertical elastic member 3333 .

[0079] Among them, the two ends of the squeezing roller 3331 are respectively set on the two mounting frames 301 for vertical sliding, and the two ends of the squeezing roller 3331 are respectively pivotally connected to the two sliders 3332, and the bottom of the two mounting frames 301 are respectively provided with vertical elastic members 3333 that only drive the corresponding sliders 3332 to move upward, wherein the slider 3332 close to the back of the box body 310 is slidably connected to the downward pressing end of the trigger downward pressing structure 334.

[0080] It should be noted that the vertical elastic member 3333 may include an extrusion spring and a vertical rod, wherein the vertical rod is vertically arranged at the bottom of the mounting frame 301 and passes through the slider 3332, so that the slider 3332 can slide on the vertical rod in the vertical direction. The vertical rod is provided with an extrusion spring, and the two ends of the extrusion spring are respectively connected to the bottom of the mounting frame 301 and the bottom of the slider 3332. When the blood transfer tube 420 enters the extrusion area, due to the action of the extrusion spring, the slider 3332 can be pushed up, so that the extrusion roller 3331 supports the bottom of the blood transfer tube 420 and cooperates with the driving structure 331 and the elastic roller to achieve extrusion of the blood transfer tube 420, so that when the rotating end of the driving structure 331 rotates, the blood transfer tube 420 can be driven to move.

[0081] To clearly illustrate the previous embodiment, in one embodiment of the present application, the trigger pressing structure 334 includes a rotating arm 3341 and a trigger rod 3342 .

[0082] Among them, the rotating arm 3341 can be rotatably set on the mounting frame 301, and the rotating arm 3341 is provided with a sliding groove along the length direction. The corresponding slider 3332 is slidably connected to the sliding groove through a connecting head. The trigger rod 3342 is set on the box cover 320, so that when the box cover 320 moves to the top of the box body 310, the trigger rod 3342 pushes the rotating arm 3341 to rotate downward, thereby driving the slider 3332 to move downward.

[0083] Specifically, when the box cover 320 is pushed toward the front of the box body 310, the box cover 320 drives the second rack 3311 to move into the box body 310, thereby driving the second gear 3312 to rotate. The second gear 3312 drives the rotating roller 3314 to rotate by engaging with the bevel gear set 3313. The rotating roller 3314 rubs against the outer wall of the blood transfusion tube 420, driving the blood transfusion tube 420 to move. The guiding devices 330 on both sides rotate relative to each other to retract the blood transfusion tube 420 into the box body 310.

[0084] When the box cover 320 moves to the top of the box body 310, that is, the box cover 320 is closed, the trigger rod 3342 pushes the rotating arm 3341 to rotate downward. The rotating arm 3341 drives the connector downward through the sliding groove limit, so that the slider 3332 drives the squeezing roller 3331 to move vertically downward, releasing the squeezing of the blood transfer tube 420 and preventing the blood transfer tube 420 from being compressed and deformed during heating.

[0085] When the box cover 320 moves in the reverse direction, that is, the box cover 320 is opened, the trigger rod 3342 is separated from the rotating arm 3341 , and the vertical elastic member 3333 pushes the slider 3332 to move upward, so that the squeezing roller 3331 presses the blood transfusion tube 420 .

[0086] At the same time, the second rack 3311 pulls the second gear 3312 to reverse, and the meshing bevel gear set 3313 drives the rotating roller 3314 to rotate in the opposite direction. The rotating roller 3314 rubs the blood transfusion tube 420 in the opposite direction, and the bilateral guiding devices 330 rotate in opposite directions to pull the blood transfusion tube 420 outward.

[0087] In one embodiment of the present application, ribs 321 are provided on both sides of the box cover 320, and magnetic blocks are embedded in the corners of the box cover 320 close to the front of the box body 310, and magnetic plates 312 matching the corresponding magnetic blocks are provided on both sides of the top of the front of the box body 310.

[0088] It should be noted that the inner walls of the ribs 321 on both sides of the box cover 320 are respectively fitted with the outer walls on both sides of the box body 310 to ensure that the box cover 320 can move in a single direction when the box cover 320 is pushed.

[0089] In summary, according to the blood transfusion equipment for real-time monitoring of multiple parameters and constant temperature regulation according to the embodiment of the present application, the blood transfusion tube 420 is automatically rolled, wrapped and heated when the box cover 320 is closed. There is no need to manually press the blood transfusion tube 420 to the heating sleeve or S-shaped groove, and the operation time is shorter, which is especially suitable for emergency rescue scenarios. Through real-time monitoring of multiple parameters, the transfused blood can be comprehensively inspected, the overall efficiency is higher, and transfusion reactions can be effectively reduced.
