Technical Field
[0001] This utility model relates to the technical field of blood transfusion and infusion pressurization devices, specifically a blood transfusion and infusion pressurization device. Background Technology
[0002] Local wars after World War II showed that 30% to 60% of deaths were caused by severe blood loss. Of these, 50% of the casualties were salvageable, but due to excessive blood loss, the wounded died before reaching medical facilities. Early and rapid fluid resuscitation under frontline medical and field transport conditions is extremely important, is of paramount importance in the treatment of the wounded, and is a key link in saving the lives of the wounded.
[0003] In existing technologies, when general infusion devices are used in bumpy and low environments, the low height of the medicine bottle slows down the infusion rate, and the bottle falling may cause secondary injuries. For example, tilting or inverting a Murphy drip tube can easily cause air embolism, increasing the risk of infusion. When transferring the device on a stretcher, someone needs to hold the medicine bottle by hand, which wastes medical manpower and is inconvenient. Furthermore, it is not possible to switch devices for use in different environments, which reduces usability. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figure 1-5 An embodiment of this utility model provides a blood transfusion and infusion pressurizer, including a pressurizing bag 1 and a tubing 2. The tubing 2 is located at the middle of the bottom of the pressurizing bag 1, and a pressure sensing guide wire 25 is located inside the tubing 2. A controller 4 is located at the middle of the bottom of the tubing 2. A touch screen display 6 is located on the front of the controller 4. A processor 16 is located at the middle of the controller 4. A multi-function button module 19 is located in the controller 4 below the processor 16. An alarm module 20 is located on one side of the top of the controller 4, and a power module 21 is located on the other side of the top of the controller 4. A connecting block 24 is located at the top of the controller 4 corresponding to the position of the tubing 2. An electronic air pump 17 is located on one side of the controller 4. The output end of the electronic air pump 17 is connected to the connecting block 24 through a pipe. An air valve 23 is located in the pipe between the electronic air pump 17 and the connecting block 24. A USB interface 7 is located on one side of the bottom of the controller 4, and a battery 18 is located in the controller 4 corresponding to the USB interface 7.
[0022] In use, under conditions of sufficient power, medical personnel can install the tubing 2 at the bottom of the pressure bag 1. Then, an external power source can be connected to the controller 4 via the USB interface 7. The power button on the controller 4 is then pressed, followed by the one-button inflation button. This causes the internal multi-function button module 19 to transmit the inflation information to the processor 16. The processor 16 collects and processes the information and controls the opening of the electronic air pump 17 and the air valve 23 in the tubing. The electronic air pump 17 then inflates the tubing 2 through the tubing and connecting block 24, thus inflating the pressure bag 1. During pressurization, the pressure sensor 22 transmits the pressure information to the processor 16 via the pressure sensing guide wire 25. The processor 16 collects and processes the information and transmits it to the alarm module 20. It collects and processes information, and provides prompts via a buzzer on the controller 4. Simultaneously, it transmits pressure information in real time to the touch screen 6 via the processor 16 for display, promptly reminding staff of pressurization information. When the pressure is too high, the depressurization button can be pressed; when the pressure is too low, the pressurization button can be pressed. This causes the multi-function button module 19 to transmit information to the processor 16 for processing of depressurization or pressurization, facilitating automatic adjustment without manual intervention, making operation more convenient. Furthermore, during charging, the power module 21 collects the battery 18's charge level and displays the information via green or red indicator lights. This information is then transmitted to the processor 16, which in turn transmits the power information to the touch screen 6, directly displaying the battery level.
[0023] A second hose 12 is provided on one side of the bottom of the pressure bag 1, and an air bladder 13 is provided at the bottom end of the second hose 12. A pressure indicator 11 is connected to one side of the top end of the second hose 12 via a branch pipe. A three-way valve 3 is provided on the second hose 12 below the pressure indicator 11. A third hose 14 is provided on the other side of the bottom of the pressure bag 1, and a pressure gauge 15 is provided on the third hose 14. An air bladder 8 is provided on the third hose 14 on one side of the pressure gauge 15. A pressure sensing guide wire 25 is provided in the branch pipe connecting the pressure indicator 11 and the second hose 12. A buzzer alarm 5 is provided on the pressure indicator 11.
[0024] In use, in an environment without power, hoses 2 (12) and 3 (14) can be connected to the bottom of the pressure bag 1. Medical personnel can then manually press the airbag 2 (13) to deliver gas through hose 2 (12) into the pressure bag 1, inflating it and compressing the blood transfusion bag or infusion bag. During pressurization, the pressure sensor 22 transmits pressure information through the pressure sensing guide wire 25 to the pressure indicator 11. The pressure indicator 11 analyzes and processes the pressure information, and the readings can be obtained from the pressure readings. Check the buzzer 5 on device 11. When the pressure is low, the buzzer 5 will be white; when the pressure is within the normal range, it will be green; and when the pressure is too high, it will be red to prevent excessive pressure from affecting its performance. Then, check the pressure information on the pressure gauge 15 on hose 3 14. When it is necessary to release pressure, press the pressure regulating device on airbag 1 8. The pressure regulating device can be a pressure button or a pressure regulating valve to release pressure. When it is time to release air after use, open the three-way valve 3 to release air.
[0025] Pressure sensors 22 are provided in the middle of the front and back of the pressure bag 1, and an infusion tube connection port is provided on one side of the bottom of the pressure bag 1.
[0026] When in use, the blood transfusion bag or infusion bag can be placed in the pressure bag 1, and the infusion tube can be connected to the blood transfusion bag or infusion bag inside through the infusion tube connection port. Then, gas can be filled into the pressure bag 1, and the pressure sensor 22 senses the pressure change, thereby pressurizing the blood transfusion bag or infusion bag inside the pressure bag 1 to perform blood transfusion and infusion.
[0027] Each pressure bag 1 has a hanging ring 9 at the middle of its top, and a binding rope 10 is provided on the top of the pressure bag 1 on both sides of the hanging ring 9.
[0028] When in use, the staff can hang the pressure bag 1 on the hanging rod via the hanging ring 9 when there is no power. When there is no hanging support rod, it can be tied to a higher device via the binding ropes 10 on both sides for convenient blood transfusion and infusion.
[0029] In this embodiment, in a power-free environment, the blood transfusion bag or infusion bag is placed inside the pressure bag 1, and the infusion tubing is connected to the internal blood transfusion bag or infusion bag through the infusion tubing connector. The pressure bag 1 is then hung on a hanging rod via the hanging ring 9. If there is no hanging support rod, it can be tied to a higher device via the binding ropes 10 on both sides for convenient blood transfusion and infusion. Then, the second and third tubing tubes 12 and 14 are connected to the bottom of the pressure bag 1. Medical personnel then manually press the second airbag 13, causing it to deliver gas through the second tubing 12 into the pressure bag 1, inflating the bag and compressing the blood transfusion bag or infusion bag. During pressurization, the pressure sensor 22 transmits pressure information through the pressure sensing guide wire 25. The pressure information is transmitted to the pressure indicator 11, which analyzes and processes the pressure data. This information can be viewed from the buzzer 5 on the pressure indicator 11. The buzzer 5 illuminates white when the pressure is low, green when the pressure is within the normal range, and red when the pressure is too high, preventing excessive pressure from affecting its effectiveness. The pressure information can then be viewed on the pressure gauge 15 on the hose 3 14. When pressure needs to be released, the pressure regulating device on the airbag 1 8 can be pressed. This device can be a pressure button or a pressure regulating valve. When deflating is required after use, the three-way valve 3 can be opened. When used in an environment with sufficient power, medical personnel can install the hose 2 at the bottom of the pressure bag 1. Then, an external power source can be connected to the controller 4 via USB interface 7. Next, press the power button on the controller 4, and then press the one-button inflation button on the controller 4. This causes the internal multi-function button module 19 to transmit the one-button inflation information to the processor 16. The processor 16 collects and processes the information and controls the opening of the electronic air pump 17 and the air valve 23 in the pipeline. This allows the electronic air pump 17 to inflate the hose 2 through the pipeline and connecting block 24, thus inflating the pressure bag 1. During pressurization, the pressure sensor 22 transmits the pressure information to the processor 16 through the pressure sensing guide wire 25. The processor 16 collects and processes the information and transmits it to the alarm module 20 for further processing. The controller 4 provides a buzzer alert, and the pressure information is simultaneously transmitted in real-time to the touchscreen display 6 via the processor 16. This allows for timely reminders to staff regarding pressurization. When the pressure is too high, the depressurization button can be pressed; when the pressure is too low, the pressurization button can be pressed. The multi-function button module 19 transmits this information to the processor 16 for automatic adjustment, eliminating the need for manual intervention and making operation more convenient. Furthermore, during charging, the power module 21 collects information on the battery 18's charge level and displays this information via green or red indicator lights. This information is then transmitted to the processor 16, which in turn displays the charge level information on the touchscreen display 6.The battery level is displayed directly. When air needs to be released, simply press the one-button air release function to release the air.
[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
