Technical Field
The utility model relates to the technical field of medical equipment, especially a manual pressure measurement device of closed.
Background
The bladder pressure is the 'gold standard' for clinical indirect measurement of the intra-abdominal pressure, the intra-abdominal pressure is an important index for judging ACS (abdominal compartment syndrome), and the monitoring of the intra-abdominal pressure has very important significance for treating critically ill patients. Therefore, monitoring of bladder pressure is widely used clinically to reflect the level of intra-abdominal pressure.
At present, the measuring device of clinical bladder pressure is almost manufactured by nurses, and the pressure value is generally obtained by manual measurement. The existing bladder pressure monitoring adopts the method that a ureter drainage bag tube close to a patient end is cut off and two tee joints are added, one tee joint is connected with a normal saline infusion tube (a normal saline tube for short), and the other tee joint is connected with a blood delivery tube (a piezometric tube for short) which is communicated with the atmosphere and used for measuring pressure; during measurement, after a patient empties the bladder, the patient takes a horizontal position, closes the pressure measuring pipe tee joint, clamps the drainage bag pipe, opens the tee joint connected with the normal saline pipe and is communicated with the catheter, and after a nurse inputs or injects normal saline into the catheter quickly to about 25 milliliters, the normal saline pipe tee joint is closed, the pressure measuring pipe tee joint is opened, the pressure measuring pipe is communicated with the urinary catheter, and the height of a water column with stable fluctuation in the pressure measuring pipe is measured by using the straight ruler with the axillary midline as a zero level, namely the measured bladder pressure value. However, the measuring device is complex to manufacture, and the workload of nurses is greatly increased; the three-way connector is easy to separate from the cut drainage bag tube and fall off, and the manufacturing process is easy to pollute; the piezometer tube is directly communicated with the air, so that the whole measuring system is not closed, and urinary tract infection related to the catheter is easily caused.
