Description

Convertible intra-abdominal pressure is flusher for measurement

Technical Field

The utility model relates to the field of medical appliances, in particular to a convertible flusher for intra-abdominal pressure measurement.

Background

Intra-abdominal pressure (IAP) is the pressure in the peritoneal cavity, normally 0-5mmHg, whereas critically ill patients commonly have 5-7mmHg, and abdominal high pressure (IAH) occurs when various high risk factors are superimposed and the intra-abdominal pressure of the patient further rises by ∈12 mmHg. This condition is classified into 4 grades according to the severity of the pressure, and if the abdominal cavity is at high pressure of 3 grades or more, the abdominal cavity compartment syndrome (ACS) is the case of combining 1 or more organ failure. Clinically, the celiac compartment syndrome (ACS) is a critical condition requiring urgent treatment and extremely high mortality. The incidence rate of the abdominal high-pressure IAH is high and the hazard is large, and research and statistical research shows that the incidence rate of the IAH of medical patients is 54.4%, the incidence rate of the IAH of surgical patients is 65%, the incidence rate of the IAH of the total population is 58.8%, the incidence rate of the intra-abdominal high pressure in the ICU is 30% -60%, the incidence rate of the ACS is lower in the ICU and is 0.9% -12%, but the death rate is as high as 50-80% (Malbrain, 2004).

Therefore, it is often clinically necessary to measure intra-abdominal pressure for abdominal pressure monitoring and screening. The specific method is mainly divided into indirect measurement and direct measurement, the direct measurement method has accurate results, but has larger wounds and high instrument consumable cost, and the indirect measurement method is mostly adopted clinically. The indirect measurement method uses transvesical pressure measurement as a gold standard, and comprises the specific operation steps and method (shown in figure 1), namely, firstly, a 16 or 18-number double-cavity or three-cavity urinary catheter is reserved in the urethra of a patient, the patient lies down as much as possible or takes a supine position to be less than or equal to 15 degrees, all urine is drained to empty the bladder, a pressure measurement pipeline (a common bladder flushing pipe at present) is connected and exhausted, physiological saline is instilled into the bladder to be less than or equal to 25ml (wsacs 2017 guideline recommendation), after 30-60 seconds of the physiological saline is injected, the liquid level of the physiological saline is stable, then, the liquid level is measured through a manual scale, and the level of the central line of the ilium armpit is taken as a zero point, so that the size of the bladder pressure value is obtained.

At present, the intermittent intra-abdominal pressure measurement is clinically performed mainly with two problems that (1) the intermittent intra-abdominal pressure measurement by using a bladder irrigator is a common intra-abdominal pressure monitoring method for clinical nurses, but hand-eye errors easily occur during the operation of hands and the nurses often have difficulty in accurately controlling the physiological saline dose injected into the bladder in consideration of efficiency. According to the guidelines updated in the world inter-Abdominal Compartment Society (ACS) 2013 and 2017, when measuring the pressure in the bladder, the dosage of physiological saline injected into the bladder is recommended to be less than or equal to 25m L, and the obtained data is more accurate. Therefore, it is necessary to provide a device which is convenient for nurses to measure and control the saline flushing amount, is convenient to operate and can ensure the accuracy of the measurement result. (2) While ensuring the accuracy of intermittent measurement of intra-abdominal pressure results, it is also necessary to ensure the tightness of the whole measurement device, so as to avoid the increase of the risk of urinary system infection of a patient caused by the break of the pipeline, and the conventional manner of injecting the flushing liquid through the injector is difficult to ensure the tightness of the whole pipeline.

The inside of the Murphy's dropper 30 is also provided with a communicating atmosphere valve 31, and when the communicating atmosphere valve 31 is opened, the inside of the Murphy's dropper 30 is communicated with the atmosphere. The irrigation tube 50 is connected at one end to the Murphy's dropper 30 and at the other end to a urinary catheter that is connected into the patient's bladder. The flushing pipe 50 is also provided with a flow regulator 40, and the flow regulator 40 is arranged at the liquid outlet rear end of the Murphy's dropper 30 and is used for regulating the flow of flushing pipe liquid entering the flushing pipe 50 in the Murphy's dropper 30.
