Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a stable pressurizing device for medical emergency blood transfusion and infusion bags. Background Art
[0002] In the field of medical emergency care, blood transfusion and infusion are crucial treatment methods. The accuracy and timeliness of their operations are directly related to the patient's life safety and treatment effectiveness. In some emergency situations, such as massive blood loss and shock, blood or liquid medicine must be quickly and stably infused into the patient's body to maintain vital signs and ensure the effectiveness of treatment. Therefore, flow rate control during blood transfusion and infusion is crucial.
[0003] Traditional blood and fluid transfusion methods rely primarily on gravity to deliver fluids, which generally meets standard treatment needs. However, when a patient is in critical condition and requires rapid blood or medication replenishment, the flow rate of gravity-based infusion falls far short of the required treatment. To address this issue, existing methods typically directly pressurize the blood and fluid bags, increasing the pressure to increase the flow rate. However, this direct pressurization method has numerous drawbacks. First, precise pressure control is difficult. Excessive pressure can easily lead to excessively rapid infusion, potentially causing serious complications such as heart failure and pulmonary edema. Meanwhile, insufficient pressure can prevent the desired rapid infusion, delaying treatment. Second, direct pressurization can easily lead to unstable pressure, resulting in fluctuating infusion flow rates. This not only affects treatment effectiveness but can also adversely affect the patient's health.
[0004] Furthermore, direct compression is a cumbersome process, requiring medical staff to frequently adjust the pressure, increasing their workload. In critical emergency situations, excessive steps can distract medical staff and hinder treatment efficiency. Furthermore, direct compression devices are typically bulky and difficult to carry, limiting their use in certain emergency scenarios, such as ambulances and field rescues. Summary of the Invention

[0081] According to an embodiment of the present invention, a stable pressurizing device for medical emergency blood transfusion and infusion bags is provided, and the pressurizing platform 30 includes a placement plate 31, which is fixedly connected to the end of the control structure 20 away from the support platform 10; a plurality of electric telescopic rods 32, which are evenly distributed on the placement plate 31 along a circular array; a mounting groove 33, which is opened through the middle position of the placement plate 31 and corresponds to the center distribution of the circle formed by the plurality of electric telescopic rods 32; an air storage bag 34, which is fixedly arranged in the mounting groove 33; wherein the extruded circular extrusion air storage bag 34 formed by the plurality of electric telescopic rods 32 realizes the pressurizing action.
[0082] Figure 1 、 Figure 2 and Figure 4 A stable pressurizing device for medical emergency blood transfusion and infusion bags is implemented in the invention. The pressurizing platform 30 is formed by a placement plate 31, an electric telescopic rod 32, a mounting groove 33 and an air storage bag 34. The placement plate 31 is fixedly connected to the end of the control structure 20 away from the support platform 10. The placement plate 31 is a thin plate structure.

Since the pressure is not directly applied to the blood transfusion or infusion bag, the pressure rises slowly, so that the pressure can be better controlled and maintained within a stable range.
[0087] According to the embodiment of the present invention, a stable pressurizing device for medical emergency blood transfusion and infusion bags is provided, and the connector 342 includes an air pressure detection module 3421, which is arranged throughout the interior of the connector 342; a ventilation channel 3422, which is connected to the corresponding end of the connector 342 corresponding to the air pressure detection module 3421; and a solenoid valve 3423, which is fixedly connected to the connector 342; wherein the air pressure detection module 3421 is used to detect the air pressure changes during pressurization in real time, the ventilation channel 3422 is used to facilitate the inhalation of external air during decompression, and the solenoid valve 3423 is used to control the opening and closing of the connector 342.

Through the analysis of the control module 21, the squeezing depth of the electric telescopic rod 32 can be accurately controlled, and then the pressure output is controlled. Secondly, a solenoid valve 3423 is fixedly provided at the bottom of the connector 342, and the solenoid valve 3423 is electrically connected to the control module 21, so that when the air pressure data transmitted by the air pressure detection module 3421 received by the control module 21 is too large, the control module 21 controls the solenoid valve 3423 to close, and stop blood transfusion. Or input air into the infusion bag, thereby better ensuring that the pressure in the blood transfusion or infusion bag is more stable, so that it can be maintained within a stable range, and the ventilation channel 3422 is set on the opposite side of the air pressure detection module 3421, and when the solenoid valve 3423 is closed, the electric telescopic rod 32 is contracted through the control module 21, and the air storage bag 34 is re-inhaled and expanded, and in the process of inhalation, air is inhaled through the ventilation channel 3422, so that the air storage bag 34 is re-inflated, which is convenient for the next pressurization treatment. After the solenoid valve 3423 is closed, the blood transfusion or infusion bag is output separately for 5-10 minutes, and the solenoid valve 3423 is opened again, and the above steps are repeated to pressurize the blood transfusion or infusion bag, and then the above steps are repeated to keep the pressure value in the blood transfusion or infusion bag at a stable state, thereby making the blood transfusion and infusion smoother.
[0089] According to the stable pressurizing device for medical emergency blood transfusion and infusion bags provided by an embodiment of the present invention, the ventilation channel 3422 is an arc-shaped tube structure, and a limiting plate 3424 is fixedly provided inside the end of the ventilation channel 3422 away from the connecting head 342, and a movable plate 3425 is provided below the limiting plate 3424. The movable plate 3425 is a circular plate movably arranged inside the ventilation channel 3422, and opens and closes when the ventilation channel 3422 is ventilated and pressurized, that is, it closes when squeezed and opens when decompressed.
[0090] Figure 7The invention also provides a stable pressurizing device for medical emergency blood transfusion and infusion bags, in which the ventilation channel 3422 is set to an arc structure, and a limiting plate 3424 is set inside one end of the ventilation channel 3422. At the same time, a movable plate 3425 is movably set below the limiting plate 3424, and the movable plate 3425 is restricted by the limiting plate 3424 so that the movable plate 3425 can only move downward. Then, when air is taken in, the movable plate 3425 opens to inflate the air storage bag 34. When pressurizing, the movable plate 3425 is pushed upward by the air pressure, and one end of the ventilation channel 3422 is closed by the limiting plate 3424, so that the squeezed gas will not leak out and all of it is transported to the blood transfusion or infusion bag, and then the blood transfusion or infusion bag is pressurized, making pressurization more convenient and making the pressure after pressurization better tend to a stable state, making the flow rate more stable.
[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
