Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pressure bag capable of automatically identifying pressurization. Background Art

[0002] Clinically, since a patient's condition requires rapid and large-scale fluid replacement, a pressurized infusion device can achieve the purpose of rapid pressurized infusion. When a patient is being rescued, the liquid in the pressure bag needs to be replaced as soon as possible, and rapid deflation is also essential. An automatic arterial pressurized infusion device is proposed in the patent document with the publication number CN108201227A. This solution uses an air pump to inflate the pressure bag, thereby achieving the effect of continuous infusion and reducing the workload of manual pressurization and inflation by medical staff. When the above device is in use, the pressure sensor is set in the pressure bag. The pressure bag will be damaged after long-term use, and the sensor installed therein cannot be reused, resulting in waste. Therefore, the present application proposes an automatic recognition and pressurized pressure bag that can replace the sensor in the pressure bag. Summary of the Invention

[0005] An air pump is fixedly installed below the connecting belt, and an output end of the air pump is connected to an air pipe.

[0006] Optionally, a mounting opening is provided in the connecting belt for the infusion bag connecting end to pass through.

[0007] Optionally, a slide groove is provided on one side of the installation groove and is located on the inner wall of the infusion bag, and the width of the slide groove is greater than the inner diameter width of the installation groove.

[0008] Optionally, clamping holes penetrating the slide groove are provided on both sides of the mounting groove.

[0009] Optionally, the pressing rod is a "U"-shaped structure, and circular blocks are connected to the front sides of both ends of the pressing rod, and grooves are provided on the back sides of the circular blocks.

[0010] Optionally, a spring is installed in the groove, and the other end of the spring is fixedly connected to the sliding mounting plate.

[0011] Optionally, a through hole is opened on one side of the cavity, and the gas pipe passes through the through hole and is sealed.

[0012] Optionally, an exhaust port is also provided on the back side of the cavity.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] The utility model is provided with a sensor structure, an air pump and an air delivery pipe. When the infusion bag is continuously infused and becomes suffocated, the sensor structure is used to control the start of the air pump, thereby achieving inflation in the cavity and pressurizing the infusion bag by the pressure bag body, thereby achieving continuous infusion. At the same time, the provision of a connecting belt can block the downward pulling force of the infusion bag when the infusion bag is installed from top to bottom in the pressure bag body, thereby achieving the limited placement of the infusion bag in the pressure bag body.

[0032] Example

[0033] like Figure 1-5As shown, the utility model proposes an automatic identification pressurized pressure bag, including an infusion bag 1 and a pressure bag body 2 for pressurizing the infusion bag 1, a cavity 21 is provided in the pressure bag body 2, and an exhaust interface is also provided on the back of the cavity 21, a connecting belt 22 is provided on the bottom inner wall of the pressure bag body 2, and a mounting port 23 for the connecting end of the infusion bag 1 to pass through is provided in the connecting belt 22. The infusion bag 1 is pulled downward from the top of the pressure bag body 2, and the connecting end of the infusion bag 1 is passed through the mounting port 23. The setting of the connecting belt 22 blocks the downward pulling force of the infusion bag 1, thereby facilitating the determination that the infusion bag 1 has reached the placement position.

[0034] like Figure 2 and Figure 3 As shown, a mounting groove 24 is provided on the inner wall of one side of the pressure bag body 2, and a slide groove 25 is provided on one side of the mounting groove 24 and located on the inner wall of the infusion bag 1. The width of the slide groove 25 is greater than the inner diameter width of the mounting groove 24, and card holes 26 that pass through the slide groove 25 are provided on both sides of the mounting groove 24.

[0035] like Figure 3-5 As shown, a sliding mounting plate 41 is detachably connected to the mounting groove 24, and a sensor structure 42 is installed on the side of the sliding mounting plate 41. The sensor structure 42 is a pressure sensor. The side of the sliding mounting plate 41 is also installed with a pressing rod 43 located on both sides of the sensor structure 42. The pressing rod 43 is a "U"-shaped structure. The front sides of both ends of the pressing rod 43 are connected with circular clamping blocks 44. The circular clamping blocks 44 are adapted to the clamping holes 26. A groove 45 is provided on the back side of the circular clamping block 44. A spring 46 is installed in the groove 45. The other end of the spring 46 is fixedly connected to the sliding mounting plate 41. The setting of the spring 46 is used to pop out the circular clamping block 44 into the clamping hole 26, so as to realize the quick installation of the sliding mounting plate 41.

[0036] like Figure 1-3 As shown, a through hole is opened on one side of the cavity 21 for exhausting the pressure bag body 2 filled with air; an air pump 3 is fixedly installed below the connecting belt 22, and the output end of the air pump 3 is connected to an air pipe 31, which passes through the through hole and is sealed.

[0037] In this embodiment, the infusion bag 1 is installed in the pressure bag body 2. During the infusion, if the pressure of the infusion bag 1 on the sensor structure 42 is less than 150 mmHg, the sensor structure 42 recognizes it and sends a signal to the control end of the air pump 3. The air pump 3 can quickly recognize it and automatically pressurize the cavity 21 to 200 mmHg through the air supply pipe 31, thereby pressurizing the infusion bag 1, ensuring continuous infusion, and reducing the workload of medical staff. When inspecting the sensor structure 42 or installing the sensor structure 42 in other pressure bag bodies 2, the pressing rod 43 is pressed toward the side close to the sliding mounting plate 41, so that the spring 46 is compressed. At this time, the circular block 44 disengages from the card hole 26, and pulls the pressing rod 43, the sliding mounting plate 41 and the sensor structure 42. The two sides of the sliding mounting plate 41 are pulled upward along the slide groove 25, thereby pulling the installation component 4 as a whole out of the outside of the pressure bag body 2.

[0038] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
