[0003] The above-mentioned pressure bag is applied to arterial pressure monitoring, and the infusion bag is pressurized by the pressure of the filled gas, but it cannot maintain the pressure (300 mmHg During monitoring, as the liquid volume decreases, the gas pressure gradually decreases, which causes the pressure to be unable to be maintained at 300 mmHg, Backflow occurs in the arterial monitoring tube, the arterial pressure monitoring waveform is inaccurate, which affects clinical judgment, and even the arterial puncture needle is blocked, and complications such as catheter dysfunction occur. It needs medical staff to observe and supplement pressure regularly to maintain the pressure at a normal level and ensure the accuracy of arterial blood pressure monitoring. Since the patients in intensive care unit are in critical condition and the condition changes quickly, the workload of nurses is large, and there is no alarm reminder when the pressure of the device is insufficient, so the nurses are easy to overlook whether the value on the surface of the telescopic rod thin rod is maintained at 300mmHg, so it cannot be guaranteed that the monitoring pressure is always at a normal level, and the arterial catheter may be blocked when the problem is found late. In addition, in order to provide a quiet and soft light resting environment for patients at night, the light in the monitoring room is insufficient, and it is inconvenient for nurses to check the pressure of the telescopic rod, and when facing multiple pressure bags, the nursing work intensity is increased.

DETAILED DESCRIPTION Example 1

[0023] The arterial pressurizing bag's pressure maintaining alarm mechanism, it is by cylinder 1, piston 2, slide bar 3, counterweight 4 and connecting head 5 constitute, transparent cylinder 1 bottom is closed, top is open, cylinder 1 is provided with piston 2, the top end face center of piston 2 is provided with slide bar 3, slide bar 3 is stacked with multiple counterweight 4 on it;Cylinder 1 bottom center is connected with connecting head 5 through communicating hose 6.The function of counterweight 4 is to press piston 2 through the gravity of counterweight 4 itself, and then the gas filled in cylinder 1 is delivered to arterial pressurizing bag through piston 2, so as to supplement the pressure in arterial pressurizing bag when the pressure in arterial pressurizing bag drops, thereby maintaining the pressure in arterial pressurizing bag.Due to the setting of multiple counterweight 4, the pressure in cylinder 1 can be adjusted by adding or subtracting the number of counterweight 4, and the pressure in arterial pressurizing bag is adjusted, so that the pressure in arterial pressurizing bag can not only quickly infuse, but also the infusion speed formed under the extrusion of arterial pressurizing bag is within the range that the patient can bear.

[0024] Scale 7 is provided on cylinder 1.Due to the gas filled in cylinder 1 to supplement the pressure of arterial pressurizing bag, the gas amount delivered from cylinder 1 to arterial pressurizing bag is equal to the infusion amount, and the amount of gas filled in cylinder 1 can be controlled through scale 7, that is, the infusion amount under constant pressure can be controlled.

[0025] The end cover 8 is threadedly mounted on the top of the cylinder 1, and the top end of the slide rod 3 extends above the end cover 8. The slide rod 3 interacts with the end cover 8 to guide the slide rod 3, and further guide the piston 2, so as to prevent the piston 2 from deviating during the lifting process, and further ensure the sealing of the piston 2 and the cylinder 1. The end of the slide rod 3 extending above the end cover 8 is threadedly mounted with a pressing plate 9, so as to limit the displacement of the slide rod 3 by the pressing plate 9 cooperating with the end cover 8, avoid the slide rod 3 from being separated from the end cover 8, and maintain the guiding effect on the piston 2. The end cover 8 below the pressing plate 9 is provided with a collision switch 10, and the end cover 8 on one side of the collision switch 10 is provided with a buzzer 11 with a power supply, and the buzzer 11 is electrically connected with the power supply through the collision switch 10. The buzzer 11 functions to alarm by buzzing when the pressing plate 9 touches the collision switch 10, so as to remind the infusion volume reaching the set value.

[0026] The cylinder 1 below the end cover 8 is provided with a fixing frame 12, so as to fix the cylinder 1 on the infusion frame through the fixing frame 12, and further fix the pressure maintaining alarm mechanism on the infusion frame. Embodiment 2

[0027] The arterial pressure bag is composed of a bag body 13, an inflation device, and the above-mentioned pressure maintaining alarm mechanism. The bag body 13 is connected with the inflation device, and the bag body 13 is communicated with the connecting head 5 of the pressure maintaining alarm mechanism.

[0028] The inflation device is a balloon 14, so as to inflate the bag body and the cylinder 1 of the pressure maintaining alarm mechanism by repeatedly pinching and releasing the balloon 14.

[0029] The bag body 13 is connected with a discharge port 16, and the discharge port 16 is provided with a discharge valve 17, so as to discharge the gas pressure in the pressure maintaining alarm mechanism and the bag body 13 through the discharge valve 17.

[0030] As an improvement, the inflation device is a gas pump 15, which can automatically inflate the bag body 1 and the cylinder 1, and can effectively reduce the labor intensity.

[0031] When the arterial pressure bag is used, the bag body 13 is hung on the infusion frame, and the end cover 8 of the pressure maintaining alarm mechanism is fixed on the support rod of the infusion frame through the fixing frame 12. After the bag body 13 and the pressure maintaining alarm mechanism are fixed, the bag body 13 is inflated through the inflation device. After the bag body 13 is filled, the gas enters the cylinder 1 of the pressure maintaining alarm mechanism, and the piston 2 is lifted by the gas pressure to overcome the gravity of the counterweight 4. When the bottom end surface of the piston 2 rises to the set scale, the inflation is stopped. After the inflation is completed, the transducer is connected to the patient's artery, and the pressure in the bag body 13 extrudes the gas to rapidly pressurize the bag. During the pressure monitoring process, the gas in the cylinder 1 is supplemented to the bag body 13 to maintain the pressure in the bag body 13, and further continuously and constantly provide the arterial pressure monitoring. When the pressure is less than 300 mmHgWhen the piston 2 drops to the bottom of the cylinder 1, the piston 2 successively touches the collision switch 10 through the slide rod 3 and the pressing plate 9, the buzzer 11 rings to alarm, reminding the medical staff that pressure needs to be added.

[0032] The pressure maintaining alarm mechanism of the arterial pressure bag and the arterial pressure bag can remind the nurse to add pressure to the pressure bag when the pressure is insufficient, without the need for regular observation and pressure supplement, and can greatly reduce the labor intensity when facing multiple pressure bags. When the device is used for pressure infusion, the pressure in the pressure bag can be adjusted by reducing (or increasing) the weight block, and then the delivery speed can be adjusted according to the individual constitution, which is beneficial to reduce the pain of patients during rapid infusion. The infusion amount can be adjusted through the scale, and an alarm can be given after the infusion is completed, further reducing the labor intensity. The problem of high labor intensity caused by the need for continuous pressure of the existing pressure bag is solved.
