Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an emergency blood rapid rewarming device. Background Technology

[0002] In emergency medicine, the timely use of blood is crucial for saving lives. Especially in cases of trauma, surgery, or other emergencies, the rapid thawing of frozen plasma has become an important technical requirement.

[0003] Existing blood rewarming devices typically use methods such as water baths, microwave heating, or electric heating to thaw blood. While these devices operate on different principles, they all share a common problem: long thawing times, often requiring tens of minutes to restore frozen plasma to a suitable transfusion temperature. This prevents the rapid delivery of the necessary blood, potentially endangering the patient's life while they wait. Furthermore, existing devices may cause loss or denaturation of blood components during the thawing process, affecting blood quality and safety, impacting clinical efficacy, and increasing transfusion risks.

[0004] Based on the above reasons, this utility model proposes an emergency blood rapid rewarming device to achieve rapid and safe rewarming of frozen plasma and meet the needs of emergency blood use. Utility Model Content

[0005] In view of the above problems, this application provides an emergency blood rapid rewarming device to solve the problems of long blood thawing time and easy denaturation during thawing in the prior art.

[0006] This application provides an emergency blood rapid rewarming device, including an outer shell, an inner shell fixedly connected to the inner cavity of the outer shell, a cover plate installed on the top surface of the inner shell, a plurality of temperature sensors symmetrically installed on the front and back of the inner wall of the inner shell, a water bath assembly provided on the inner shell, microwave modules provided on the left and right outer walls of the inner shell, displacement components provided on the microwave modules, a control module provided on the outer shell, and a clamping assembly provided near the top surface of the inner shell.

[0007] In some embodiments, the displacement component includes a mounting frame, and two mounting frames are provided, each fixedly connected to a microwave module. The same rectangular frame is movably connected to both mounting frames. Three fixing plates are fixedly connected to the front and rear side walls of the rectangular frame. The same threaded rod is movably connected between the two fixing plates on the left and right sides. The threaded rod is threadedly connected to the mounting frame. Another threaded rod is threadedly connected to the fixing plate at the center of the front side. A motor is fixedly connected to one end of each of the three threaded rods.

[0008] In some embodiments, the clamping assembly includes clamping plates, two of which are symmetrically arranged on the left and right sides of the inner cavity of the inner shell, and two crossbars are symmetrically and movably connected to the two clamping plates. The crossbars pass through the inner shell and are fixedly connected to the inner wall of the outer shell. Two springs are sleeved on each crossbar. One end of the spring is fixedly connected to the clamping plate, and the other end of the spring is fixedly connected to the inner wall of the inner shell.

[0009] In some embodiments, the control module includes a control screen, which is fixedly mounted on the front side wall of the housing, and a control button and a charging port are installed on the lower side of the control screen. An analysis module and a built-in power supply are installed between the housing and the inner housing.

[0010] In some embodiments, the water bath assembly includes a heating circulation pump, which is fixedly installed on the bottom surface of the inner shell and communicates with the inner cavity of the inner shell. A plurality of connecting pipes are fixedly connected to the heating circulation pump, the connecting pipes being concave and communicating with the inner cavity of the inner shell.

[0011] In some embodiments, a vertical rod is movably connected to the rear fixing plate, and both ends of the vertical rod are fixedly connected to the inner wall of the outer casing.

[0012] In some embodiments, a handle is fixedly connected to the top surface of the cover plate.

[0013] The above scheme utilizes temperature sensors to perform multi-point temperature measurements on the blood bag. Based on the data analysis and processing from the temperature sensors, a motor is activated, driving a threaded rod to rotate. The vertical rotation of the threaded rod moves the rectangular frame, allowing for height adjustment of the microwave module. The horizontal rotation of the threaded rod moves the mounting frame on the rectangular frame, allowing for front-to-back position adjustment of the microwave module. Through these displacements, the microwave module can be positioned at an abnormal temperature location, and the blood is then microwave-heated using the module. This not only increases the blood rewarming speed but also improves the temperature uniformity and reduces the impact on the blood. By adding warm water into the inner cavity of the shell, a water bath operation for the blood can be achieved. By activating a heating circulation pump, the warm water in the inner shell is continuously circulated and heated for temperature control, ensuring a stable and sufficient water bath temperature, further improving the efficiency of blood rewarming.

[0023] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, this application embodiment provides an emergency blood rapid rewarming device, including an outer shell 1, an inner shell 2 fixedly connected to the inner cavity of the outer shell 1, a cover plate 3 installed on the top surface of the inner shell 2, a plurality of temperature sensors 4 symmetrically installed on the front and back of the inner wall of the inner shell 2, microwave modules 5 are provided on the left and right outer walls of the inner shell 2, and displacement components 6 are provided on the microwave modules 5. The displacement components 6 include mounting frames 9, two mounting frames 9 are provided, and the mounting frames 9 are fixedly connected to the microwave modules 5 respectively. The same rectangular frame 10 is movably connected to the two mounting frames 9. Three fixing plates 11 are fixedly connected to the front and back side walls of the rectangular frame 10. The same threaded rod 12 is movably connected between the two fixing plates 11 on the left and right sides. The threaded rod 12 is threadedly connected to the mounting frame 9. Another threaded rod 12 is threadedly connected to the front center fixing plate 11. A motor 13 is fixedly connected to one end of the three threaded rods 12. In the technical solution of this embodiment, during the blood rewarming process, the blood bag is subjected to multi-point temperature measurement based on the temperature sensor 4. Based on the data analysis and processing of the temperature sensor 4, the motor 13 is started. The motor 13 drives the threaded rod 12 to rotate. The rotation of the vertical threaded rod 12 drives the rectangular frame 10 to move, thereby adjusting the height of the microwave module 5. The rotation of the horizontal threaded rod 12 drives the mounting frame 9 to move on the rectangular frame 10, thereby adjusting the front and rear position of the microwave module. Through the above displacement, the microwave module 5 can be adjusted to the abnormal temperature position, and the blood is microwave-heated based on the microwave module 5. This not only improves the blood rewarming speed but also improves the temperature uniformity of the rewarming and reduces the impact on the blood. A vertical rod 22 is movably connected to the rear fixing plate 11. The two ends of the vertical rod 22 are fixedly connected to the inner wall of the outer shell 1, which improves the stability of the vertical movement of the rectangular frame 10, thereby making the adjustment of the microwave module 5 highly accurate. A water bath assembly 7 is provided on the inner shell 2. The water bath assembly 7 includes a heating circulation pump 25. The heating circulation pump 25 is fixedly installed on the bottom surface of the inner shell 2 and is in communication with the inner cavity of the inner shell 2. Several connecting pipes 23 are fixedly connected to the heating circulation pump 25. The connecting pipes 23 are concave and are in communication with the inner cavity of the inner shell 2. In the technical solution of this embodiment, by adding warm water into the inner cavity of the inner shell 2, the blood can be bathed. By starting the heating circulation pump 25, the warm water in the inner shell 2 is continuously circulated and heated and temperature controlled, so that the water bath temperature is stable and sufficient, and the efficiency of blood rewarming is further improved. A control module is provided on the outer shell 1. The control module includes a control screen 17. The control screen 17 is fixedly installed on the front side wall of the outer shell 1. A control button 18 and a charging port 19 are installed on the lower side of the control screen 17. An analysis module 20 and a built-in power supply 21 are installed between the outer shell 1 and the inner shell 2. In the technical solution of this embodiment, the control panel 7 and control button 18 can be used to control the rewarming device. The analysis module 20 can analyze and process the input parameters and the data monitored by the temperature sensor 4 to improve the blood rewarming quality. The charging port 19 can be used to charge the built-in power supply 21, making it convenient to carry and use the rewarming device. A clamping assembly 8 is provided near the top surface of the inner shell 2. The clamping assembly 8 includes clamping plates 14. Two clamping plates 14 are symmetrically arranged on the left and right sides of the inner cavity of the inner shell 2. Two crossbars 15 are symmetrically and movably connected to the two clamping plates 14. The crossbars 15 pass through the inner shell 2 and are fixedly connected to the inner wall of the outer shell 1. Two springs 16 are sleeved on each crossbar 15. One end of the spring 16 is fixedly connected to the clamping plate 14, and the other end of the spring 16 is fixedly connected to the inner wall of the inner shell 2. In the technical solution of this embodiment, by placing the top surface of the blood bag between two clamps 14, the clamps 14 on both sides clamp the blood bag under the elastic force of the spring 16, so that the blood bag can be stably placed in the inner shell 1. This not only facilitates water bathing, but also improves the accuracy of microwave rewarming, resulting in a better blood rewarming effect. A handle 24 is fixedly connected to the top surface of the cover plate 3, which makes it easy to carry the rewarming device and facilitates emergency use.
