Example 10
Referring to fig. 1, fig. 1 is a schematic diagram of an overall structure of a monitoring system according to an embodiment of the invention.
The present embodiment provides a disposable intra-abdominal pressure monitoring system substantially the same as that provided in embodiment 3, the main difference being that: the first conduit 301 is made of transparent PP, and the second conduit 402 is a medical rubber tube.
The PP in this embodiment is a medical PP, which has the following characteristics: 1. high-temperature sterilization: the PP plastic material is semi-crystalline material with high melting point, good heat resistance and disinfection at the temperature above 100 ℃. Yield strength, tensile strength, compressive strength, hardness and elasticity are higher than those of Polyethylene (PE); 2. low temperature resistance, impact resistance: the brittleness of the homo-PP is larger, and the homo-PP and the random co-PP synthesized by ethylene have better toughness and stronger impact strength. The product usually used under the low temperature condition is to choose the copolymerization PP as much as possible or add thermoplastic rubber to modify the PP, so as to increase the flexibility and the low temperature impact resistance; the first guide tube 301 and the second guide tube 402 which are made of transparent PP are convenient for medical staff to observe the urine discharge condition and the physiological saline filling condition; the medical rubber tube in the embodiment is externally used and is used for liquid delivery.
In summary, an embodiment of the present invention provides a disposable intra-abdominal pressure monitoring system, which includes a pressure calibration measurement mechanism 1 and a urine volume monitoring mechanism 2 connected in sequence, wherein the pressure calibration measurement mechanism 1 is connected with a detained urinary catheter. The pressure calibration measuring mechanism 1 is used for calibrating the pressure of the bladder after the bladder is emptied, and then carrying out stable monitoring; the urine volume monitoring mechanism 2 is used for monitoring the urine volume of a patient; according to the invention, accurate monitoring of intra-abdominal pressure is realized by butting the pressure calibration measuring mechanism 1 and the urine volume monitoring mechanism 2, compared with the prior art, large-scale equipment is needed for monitoring, the system is more convenient to use, medical staff is more convenient to use, the suitability in clinic is wide, meanwhile, the pain and infection risk of patients can be effectively reduced, the workload of the medical staff is reduced, large-scale equipment is not needed to be purchased, the medical monitoring cost caused by intra-abdominal pressure measurement can be effectively reduced, the space occupation rate is reduced, the practicability of the whole system is improved, and the system is convenient for popularization and use in a large range.
In actual use, the medical staff connects the pressure calibration measuring mechanism 1 with the detained urinary catheter on the patient, then uses the urine volume monitoring mechanism 2 to detect the urine volume of the patient, and finally uses the pressure calibration measuring mechanism 1 to calibrate the intra-abdominal pressure and measure.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
