[0002] In the field of medical emergency, emergency blood transfusion is very important for maintaining the normal vital signs of patients. During the emergency blood transfusion process, in order to facilitate the rapid transfusion of large amounts of blood to patients, the infusion process needs to be pressurized to increase the blood delivery speed. At the same time, it is necessary to prevent blood cell damage and unstable infusion flow rate caused by uneven pressure.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Shaking the blood transfusion bag with the help of the machine's built-in shaking mechanism can save human resources; medical staff do not need to frequently shake the blood transfusion bag manually, and can devote more energy to patient condition monitoring and comprehensive care, optimize medical resource allocation, and improve overall medical service efficiency. On the other hand, compared with manual shaking operations that are difficult to ensure consistency in shaking frequency and amplitude, the equipment can shake stably with precisely set parameters, which can effectively avoid fluctuations in blood flow rate caused by unstable shaking, ensure a smooth and constant flow rate during transfusion, and allow blood to be transfused into the patient's body in the best condition, ensuring the reliability and safety of the transfusion effect; at the same time, stable mechanical shaking can reduce the friction between the blood and the bag wall and the local pressure changes caused by uneven shaking, reduce the risk of damage to blood components, and better maintain the activity and component integrity of the blood, thereby further improving the quality of transfusion therapy;

[0030] 2.

Medical staff can place multiple blood transfusion bags in the blood transfusion box at the same time, and complete the automatic replacement of blood transfusion bags through the control equipment, thereby further saving manpower;

[0033] 5. A peristaltic pump is used as a pressurizing device for emergency blood transfusion equipment. When working, the first motor drives the rotating block to rotate, and the rollers on the rotating block squeeze the pump tube in turn, forming a positive pressure in front of the roller to push the liquid, and a negative pressure at the rear to suck the liquid. This cycle achieves stable liquid delivery.

[0045] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the invention more thorough and comprehensive.

[0046] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. The terms "parallel", "first", "second", "third" and similar expressions used herein are for illustrative purposes only.

[0047] See also Figure 1 , which shows a structural schematic diagram of an emergency blood transfusion device with a stable flow rate provided in the first embodiment of the present application, wherein the emergency blood transfusion device includes a blood transfusion box 100, a fixing seat 200, an injection seat 300, a shaking mechanism 400 and a controller 500.

[0048] Specifically, the blood transfusion box 100 has a built-in blood transfusion cavity 110, and an opening is provided at the upper end of the blood transfusion box 100, and an openable and closable box cover 120 is provided on the opening; a fixing seat 200 and an injection seat 300 are installed in the blood transfusion cavity 110, and the fixing seat 200 is provided with a limiting member 210 and a first clamping mechanism 220 on opposite sides away from the injection seat 300 and close to the injection seat 300, respectively; wherein, the limiting member 210 is used to limit one end of the blood transfusion bag, so as to effectively avoid the risk of the blood transfusion bag being misplaced or even thrown out during the operation of the equipment, and the first clamping mechanism 220 is used to fix the blood transfusion interface of the blood transfusion bag to the fixing seat 200, so as to facilitate the subsequent connection with the blood transfusion tube.

[0049] Preferably, the above-mentioned limiting member 210 can also be provided at other positions of the fixing seat 200 to limit the blood transfusion bag, or it can be a mechanism that can be adjusted to adapt to different sizes of blood transfusion bags, such as an elastic clip mechanism that clamps the blood transfusion bag by the restoring force generated by elastic deformation. By adjusting the opening and closing strength and shape design of the clip, it can adapt to the limiting requirements of blood transfusion bags of different specifications, and can effectively prevent the blood transfusion bag from slipping or displacement. For another example, a small vacuum adsorption area is provided on the fixing seat 200, and a local vacuum environment is generated by connecting equipment such as a vacuum pump. When one end of the blood transfusion bag approaches the area, it is tightly adsorbed on the fixing seat 200 under the action of vacuum negative pressure, which can provide a strong adsorption force to ensure that the position of the blood transfusion bag is fixed, and blood transfusion bags of different weights and materials can be adapted by adjusting the vacuum degree.

[0050] The injection seat 300 is provided with a translation drive mechanism 310 and a second clamping mechanism 320. The second clamping mechanism 320 is located on the translation drive mechanism 310. The second clamping mechanism 320 is used to fix the plug of the blood transfusion tube on the injection seat 300 and toward the fixed seat 200. The translation drive mechanism 310 can drive the second clamping mechanism 320 to approach or move away from the first clamping mechanism 220, so that when performing blood transfusion, the plug of the blood transfusion tube can be accurately inserted into the blood transfusion interface of the blood transfusion bag and the plasma can be smoothly discharged.

[0051] A shaking mechanism 400 is provided in the blood transfusion cavity 110, and the shaking mechanism 400 is used to drive the fixing seat 200 to move so as to cause the blood transfusion bag it carries to shake; specifically, since blood has certain coagulation characteristics and its internal components are prone to precipitation when standing still, regular shaking can effectively break the coagulation structure that may be formed inside the blood, prevent the aggregation of components such as platelets, and prevent the blood from coagulating into lumps. At the same time, it can also ensure that various components in the blood, such as red blood cells, white blood cells, plasma proteins, etc., are evenly mixed to avoid uneven distribution of components due to precipitation, thereby ensuring the safety and effectiveness of blood transfusion, so that the blood transfused into the patient's body is always in good condition, and the role of blood transfusion therapy is maximized.

[0052] Preferably, the shaking mechanism 400 , the first pressing mechanism 220 , the translation driving mechanism 310 and the second pressing mechanism 320 are all electrically connected to the controller 500 .

[0053] The working principle of the first-aid blood transfusion device with a stable flow rate provided in the first embodiment of the present application is as follows:

[0054] First, the medical staff places the blood transfusion bag on the fixed seat 200 in the blood transfusion cavity 110, and limits the end of the blood transfusion bag away from the blood transfusion interface through the limiter 210, and the first clamping mechanism 220 fixes the blood transfusion interface of the blood transfusion bag. Then, the blood transfusion blood plug is placed on the injection seat 300, and the second clamping mechanism 320 fixes it and faces the fixed seat 200. The controller 500 can control the translation drive mechanism 310, so that the second clamping mechanism 320 drives the blood transfusion blood plug close to the first clamping mechanism 220, so that the plug is inserted into the blood transfusion interface to establish a blood transfusion pathway. During the blood transfusion process, the controller 500 controls the shaking mechanism 400 to drive the fixed seat 200 to shake, which drives the blood transfusion bag to shake, prevent blood coagulation and component precipitation, and ensure that blood transfusion is safe, stable, and efficient.

[0055] The beneficial effects of the first embodiment of the present application of a blood transfusion device with a stable flow rate for emergency use are as follows:

[0056] On the one hand, shaking the blood transfusion bag with the help of the built-in shaking mechanism 400 of the machine can save human resources; medical staff do not need to frequently shake the blood transfusion bag manually, and can devote more energy to patient condition monitoring and comprehensive care, optimize medical resource allocation, and improve overall medical service efficiency. On the other hand, compared with manual shaking operations, which are difficult to ensure the consistency of shaking frequency and amplitude, the equipment can shake stably with precisely set parameters, which can effectively avoid blood flow rate fluctuations caused by unstable shaking, ensure a smooth and constant flow rate during blood transfusion, and enable blood to be transfused into the patient's body in the best state, ensuring the reliability and safety of the blood transfusion effect. At the same time, stable mechanical shaking can reduce the friction between the blood and the bag wall and the local pressure changes caused by uneven shaking, reduce the risk of damage to blood components, and better maintain the activity and component integrity of the blood, thereby further improving the quality of blood transfusion therapy.

[0057] Preferably, if Figure 2As shown, the shaking mechanism 400 includes a workbench 410 and a first rotary drive mechanism, and the fixed seat 200 and the injection seat 300 are both installed on the workbench 410; the first rotary drive mechanism is drivingly connected to the workbench 410. Specifically, when only the shaking mechanism 400 mechanically shakes the fixed seat 200 alone, the generated vibration and displacement will directly act on the blood transfusion interface of the blood transfusion bag and the connected blood transfusion tube plug, making the plug easy to loosen and cause blood leakage, affecting the stability of the blood transfusion process. In severe cases, the plug may even fall off, causing the interruption of blood transfusion, delaying the patient's treatment, causing medical accidents and endangering life. Letting the fixed seat 200 and the injection seat 300 shake in coordination driven by the first rotary drive mechanism can evenly disperse the impact force, make the plug firmly connected, effectively avoid the above risks, and ensure the smooth progress of blood transfusion.

[0058] Preferably, the blood transfusion channel can be designed with a bellows, which can effectively buffer and adapt to changes in tension, and reduce the risk of the blood transfusion channel being stretched due to the movement of the injection seat 300 during shaking, which may cause the plug to be pulled out. At the same time, the fixed seat 200 and the injection seat 300 can be arranged at the center and edge of the workbench 410, and the pipeline passing through the two passes through the center of the workbench 410, so that the length of the blood transfusion channel between the injection seat 300 and the fixed seat 200 is always constant relative to the center of the workbench 410 during the shaking process, thereby preventing the plug from being pulled out. A portion of the pipeline can also be reserved on the injection seat 300. When the blood transfusion channel is stretched due to shaking, the reserved pipeline can be replenished in time to further ensure that the pipeline is always in a suitable tension state, effectively maintaining the stability and safety of the blood transfusion process.

[0059] In emergency blood transfusion scenarios, multiple blood bags are often needed to meet the patient's large blood transfusion needs. Since the blood in each blood bag comes from different blood donors, they cannot be transfused at the same time. Before each transfusion, the previous bag of blood in the pipeline should be flushed clean with saline to ensure that the newly transfused blood components can smoothly enter the patient's body, ensuring the safety and effectiveness of emergency blood transfusion.

[0060] In one embodiment, see Figure 3 , a plurality of fixing seats 200 are provided in the blood transfusion box 100;

[0061] The shaking mechanism 400 includes a rotating table 420, a rotating annular table 430, a second rotating drive mechanism 450 and a third rotating drive mechanism 460. The rotating annular table 430 is located at the periphery of the rotating table 420 and is coaxially arranged with the rotating table 420; a plurality of fixed seats 200 are all arranged on the rotating annular table 430 and are arranged at circumferential intervals around the rotating annular table 430, and the injection seat 300 is arranged on the rotating table 420; the second rotating drive mechanism 450 is drivingly connected to the rotating table 420, and the third rotating drive mechanism 460 is drivingly connected to the rotating annular table 430.

[0062] Specifically, multiple fixing seats 200 and multiple fixing seats 200 can hold multiple different blood transfusion bags and saline bags. When the blood transfusion bag is converted, the control console drives the translation drive mechanism 310 to pull out the plug of the blood transfusion tube from the blood transfusion interface of the blood transfusion bag, and then the second rotation drive mechanism 450 remains stationary, and the third rotation drive mechanism 460 is used to rotate the rotating annular table 430 to convert the fixing seat 200 corresponding to the plug of the blood transfusion tube from the fixing seat 200 carrying the previous blood transfusion bag to the fixing seat 200 carrying saline, and then control the plug to be inserted into the saline bag to inject saline into the human body, and then convert it to the blood transfusion of the next blood transfusion bag in the same way; and when the blood needs to be shaken, the control console synchronously controls the second rotation drive mechanism 450 and the third rotation drive mechanism 460 to drive the rotating table 420 and the rotating annular table 430 respectively so that the fixing seat 200 and the injection seat 300 rotate back and forth coaxially and synchronously to prevent the plug from being forced to fall off due to a single movement.

[0063] On the one hand, the multiple fixed seats 200 can be used to place different blood transfusion bags and saline bags, which is convenient for flexible switching during the blood transfusion process, ensuring the continuity of blood transfusion and avoiding the impact of patient treatment due to untimely replacement of blood bags. On the other hand, through the cooperation of a specific driving mechanism, the conversion of the blood transfusion tube plug between the blood transfusion bag and the saline bag is accurately realized, with a high degree of automation, reducing human operating errors, and improving the safety and efficiency of blood transfusion. At the same time, in the shaking link, the console synchronously controls the rotating table 420 and the rotating ring table 430, so that the fixed seat 200 and the injection seat 300 rotate coaxially and synchronously, effectively preventing the plug from falling off due to uneven force caused by a single movement, and maintaining the stability of the blood transfusion pathway, ensuring that blood and saline can be smoothly and stably injected into the patient's body, providing reliable, efficient and safe protection for emergency blood transfusion and other scenes, and can also shake other blood transfusion bags to be used on the fixed seat 200 to prevent the blood components in the blood bags to be used from precipitating or coagulating, so that they are always in the best transfusion state. This not only reduces the risk of quality deterioration due to blood standing still for a long time, but also ensures that the blood bag can be put into use immediately when an emergency blood transfusion is needed. This makes the equipment not only used for blood transfusion, but also can be used as a device to maintain the activity of blood bags when it is not involved in blood transfusion work to a certain extent, greatly expanding the practicality of the equipment.

[0064] It is understandable that the shaking mechanism 400 can also be a multi-layer rotating platform, with the bottom layer being a rotating circular table 430, on which a plurality of fixed seats 200 are arranged at intervals, on which blood transfusion bags and saline bags can be placed. The upper layer is a rotating table 420, on which the injection seat 300 is installed. When the blood transfusion bag is replaced, the motor drives the rotating circular table 430 to rotate, accurately switching the positions of different fixed seats 200, so that the blood transfusion tube plug can be smoothly switched from one blood transfusion bag to another blood transfusion bag or saline bag. When shaking is required, the motors of the upper and lower layers work together to make the rotating table 420 and the rotating circular table 430 rotate and shake synchronously and coaxially. The shaking mechanism 400 can also be on two tracks, with the sliders 315 on one track being arranged at intervals with multiple fixing seats 200 for placing blood transfusion bags and saline bags, and the sliders 315 on the other track being installed with the injection seat 300. When the blood transfusion bag is replaced, the slider 315 on one track moves, and the other track remains stationary or one track moves in the opposite direction relative to the other track, so that different fixing seats 200 positions are switched, so that the blood transfusion tube plug can be smoothly switched from one blood transfusion bag to another blood transfusion bag or saline bag. When shaking is required, the two guide rails drive the blood transfusion bag or saline bag to shake left and right synchronously and in the same direction.

[0065] In one embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the emergency blood transfusion equipment also includes a pressurizing device 600, which is arranged in the blood transfusion cavity 110; the controller 500 is electrically connected to the pressurizing device 600 to drive the pressurizing device 600 to guide the blood in the blood transfusion bag to flow into the blood transfusion blood channel.

[0066] Preferably, if Figure 4 , Figure 5 and Figure 6 As shown, the pressurizing device 600 includes a first motor 610, a pump head 620 and a pump tube 630. The pump head 620 includes a housing 621, a rotating block 622 and a plurality of rollers. The housing 621 is provided with a receiving chamber 624, an inlet 625 connected to the receiving chamber 624 and an outlet 626 connected to the receiving chamber 624.

[0067] The rotating block 622 is located in the accommodating chamber 624; the first motor 610 is drivingly connected to the rotating block 622 and drives the rotating block to rotate axially relative to the accommodating chamber 624 of the shell 621; the rotating block 622 is connected to a plurality of squeezing rollers 623, and the plurality of squeezing rollers 623 are distributed axially rotating around the rotating block 622; the pump tube 630 enters the shell 621 from the inlet 625 and leaves the shell 621 from the outlet 626 along the wall of the accommodating chamber 624; the pump tube 630 is located between the squeezing roller 623 and the wall of the accommodating chamber 624 and is squeezed by the squeezing roller 623.

[0068] Specifically, Figure 5As shown, when the first motor 610 is started, the rotating block 622 is driven to rotate axially in the accommodating chamber 624 of the housing 621. The multiple squeezing rollers 623 connected to the rotating block 622 rotate synchronously therewith. Since the pump tube 630 is located between the squeezing rollers 623 and the cavity wall of the accommodating chamber 624, the rollers will squeeze the pump tube 630 in sequence as the rollers rotate. At the inlet 625 end, the rollers squeeze the pump tube 630 to form a local negative pressure, thereby sucking the blood in the blood transfusion bag into the pump tube 630; when the rollers rotate to the outlet 626 end, the squeezing of the pump tube 630 pushes the blood in the tube out, prompting the blood to flow into the blood transfusion channel. The pressurizing device 600 can adjust the speed of the first motor 610 through the controller 500 to adjust the working efficiency of the pump to accurately control the blood delivery speed and flow rate, ensuring that the blood is stably, quickly and accurately delivered to the patient's body, buying precious time to save the patient's life, and at the same time avoiding adverse effects on the patient due to unstable pressure or excessive or insufficient flow, effectively ensuring the safety and efficiency of blood transfusion therapy.

[0069] It can be understood that the pressurizing device 600 can also be a piston pressurizing device 600 composed of a piston cylinder, a piston and a driving mechanism, and the piston reciprocates in the piston cylinder under the push of the driving mechanism. Both ends of the piston cylinder are provided with a one-way valve. When the piston moves away from the blood transfusion bag, negative pressure is formed in the piston cylinder, and the blood in the blood transfusion bag is sucked into the piston cylinder; when the piston moves toward the blood transfusion bag, pressure is applied to the blood in the cylinder, and under the action of the one-way valve, the blood is pressed into the blood transfusion tube through the pipeline.

[0070] See also Figure 7 and Figure 8 The injection seat 300 includes a base and side walls extending upward from opposite sides of the base, and a mounting groove 330 is provided on the side walls; the translation driving mechanism 310 includes a slide rail 311, a driving rack 312, a second motor 313, a driving gear 314 and a slider 315;

[0071] The slide rail 311 is installed on the side wall of the installation groove 330, the slider 315 is slidably connected to the slide rail 311, the driving rack 312 is installed on the slider 315, the driving gear 314 is meshed with the driving rack 312, the second motor 313 is drivingly connected to the driving gear 314, the slider 315 extends in the horizontal direction to form an extension platform 316, and the second clamping mechanism 320 is arranged on the side of the extension platform 316 away from the slider 315.

[0072] When the relative position of the blood transfusion tube plug and the blood transfusion interface of the blood transfusion bag needs to be adjusted, the second motor 313 is started to drive the driving gear 314 to rotate, and the driving gear 314 drives the slider 315 equipped with the driving rack 312 to move smoothly in the horizontal direction along the slide rail 311, thereby driving the second clamping mechanism 320 provided on the extension platform 316 of the slider 315 to move synchronously, thereby achieving precise control of the position of the blood transfusion tube plug, so that it can be close to or away from the blood transfusion interface of the blood transfusion bag for the insertion or removal of the plug.

[0073] Specifically, Figure 7 As shown, the second clamping mechanism 320 includes a first support block 321, a first clamping block 322 and a bolt 323; the first support block 321 is fixed to the extension platform 316, the first support block 321 is provided with a sinking hole, the bolt 323 is rotatably connected to the sinking hole, the first clamping block 322 is threadedly connected to the bolt 323 and is located between the first support block 321 and the bolt 323. When in use, the blood transfusion tube plug is placed between the first support block 321 and the first clamping block 322, the bolt 323 is rotated, and as the bolt 323 rotates, the first clamping block 322 will move along the axial direction of the bolt 323. When the first clamping block 322 moves downward, it will gradually approach the first support block 321 until the blood transfusion tube plug located between the two is tightly clamped, thereby achieving the fixation of the blood transfusion tube plug.

[0074] In one embodiment, if Fig. 9 As shown, the limiter 210 is a hook 211; the first clamping mechanism 220 includes a second support block 221, a second clamping block 222 and an elastic component 223; the second support block 221 is fixed to the fixing seat 200, and the second support block 221 is connected to the second clamping block 222 through the elastic component 223, and the second clamping block 222 is used to fix the blood transfusion interface of the infusion bag on the second support block 221. When in use, pull up the second clamping block 222, place the blood transfusion interface of the blood transfusion bag between the second clamping block 222 and the second support block 221, and put down the second clamping block 222. Under the action of the elastic element, the second clamping block 222 has a tendency to return to its original position, and squeezes the blood transfusion interface to fix it. Preferably, the elastic element can be a spring or a rubber elastic body. It can be understood that the first clamping mechanism 220 and the second clamping mechanism 320 can also be a clamping mechanism with a snap-on connection or a magnetic clamping mechanism.

[0075] Preferably, if Figure 2 and Figure 3As shown, a pipeline guide block 700 is also provided in the blood transfusion cavity 110, and an output port 626 is provided on the blood transfusion box 100. The pipeline guide block 700 is used to guide the blood transfusion channel to the output port 626. The pipeline guide block 700 is provided on one side of the output port 626 of the injection seat 300 to guide the blood transfusion channel to smoothly connect with the pressurizing device 600 provided in different planes; it can also be provided at the output port 626 end of the pressurizing device 600 (not shown in the figure) to guide the blood transfusion channel after pressurization to the output port 626.

[0076] Preferably, the emergency blood transfusion equipment is also provided with a heating device and a temperature sensor (not shown in the figure), and the output end of the heating device and the temperature sensor are both installed in the blood transfusion cavity 110; the temperature sensor and the heating device are both electrically connected to the controller 500, and the temperature sensor is used to send temperature information to the controller 500.

[0077] Specifically, the heating device can increase the blood temperature, prevent the patient's body temperature from dropping suddenly due to the transfusion of a large amount of low-temperature blood, and cause vasoconstriction, chills, arrhythmia, etc., to ensure safe and comfortable blood transfusion; at the same time, maintain the activity of blood components, ensure the normal function of coagulation factors, platelets, etc., and ensure blood quality. The temperature sensor monitors the blood temperature of the transfusion cavity 110 in real time and feeds back to the controller 500. The controller 500 controls the heating device according to the temperature data provided by the temperature sensor to keep the blood in the transfusion bag at a suitable temperature for the human body. When the temperature is low, start or increase its power, and adjust it accordingly after reaching the standard, so that the blood temperature is constant in the ideal range, preventing excessive temperature from destroying blood components and causing protein denaturation, blood cell damage, etc., which not only ensures the quality of blood transfusion, but also reduces the possibility of equipment failure due to abnormal temperature, improves the safety and reliability of the equipment, and provides strong support for the smooth implementation of emergency blood transfusion.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
