Problems solved by technology

The disadvantage of simply connecting the measuring device or the pressure transducer kit of the multi-function monitor for measurement is that the repeated connection of the syringe and the measuring device is easy to cause contamination, and the amount of liquid drawn is not accurate and easy to form air bubbles, resulting in measurement errors

Embodiment 1

[0027] Embodiment 1: as figure 1 , 2 , 3, and 4, the bedside bladder pressure measuring instrument integrating water injection and measurement includes a medical tee 1, a liquid transmission tube 2, a hydraulic measuring device 3, and an injection device 4, and a liquid is connected to a port of the medical tee 1. Transmission tube 2, the liquid transmission tube is connected with a conventional urinary catheter, the injection device is set at the other port of the medical tee, the third port of the medical tee is a closed end, the hydraulic measuring device is set at the front end of the injection device and communicated with it, the medical tee The valve 13 on the top is used to control the opening and closing of the injection device and the liquid transmission pipe, wherein the hydraulic measuring device 3 is a pressure gauge; the injection device 4 includes a cylinder 5, a push rod 6, and a push rod fixing assembly for preventing the push rod from sliding. The push rod is...

Embodiment 2

[0029]Embodiment 2: The device structure of this embodiment is different from that of Embodiment 1 in that: the push rod fixing component is an external thread 7 arranged on the push rod 6 and an internal thread matched with the external thread and arranged at one end of the cylinder (see Figure 5 ), the length of the liquid transfer pipe is 0.5m.

Abstract

The invention discloses a water injection and measurement integrated bedside intravesical pressure measurement instrument. The bedside intravesical pressure measurement instrument comprises a medical tee joint, a liquid delivery tube, a liquid pressure measurement device and an injection device. The liquid delivery tube is connected to one port of the medical tee joint and connected with a conventional catheter, the injection device is arranged at another port of the medical tee joint, and the third port of the medical tee joint is a closed end. The liquid pressure measurement device is arranged at the front end of the injection device and communicated with the same, and a valve on the medical tee joint is used for controlling opening and closing of the injection device and the liquid delivery tube. The bedside intravesical pressure measurement instrument is convenient to use, and possibility of contamination and urinary tract infection in a traditional operation process is avoided; water injection amount can be quantified precisely to reach an optimal water injection quantity required in international guidelines, and measurement results can be more accurate; accurate reading of the measurement results can be realized to guarantee accuracy of the results; the measurement instrument is low in cost, portable, suitable for various medical treatment environments and convenient to popularize.

Description

technical field [0001] The invention relates to a closed bedside bladder pressure measuring instrument integrated with water injection and measurement, which belongs to the field of medical equipment. Background technique [0002] Intra-abdominal pressure (intra-abdominal pressure, IAP): It is the pressure in the stable state in the closed cavity of the abdominal cavity, which is mainly generated by the hydrostatic pressure of the abdominal viscera. Normally, IAP is maintained at about 0mmHg (1mmHg=0.133kPa). Patients fluctuate in 5 ~ 7mmHg. [0003] The latest guidelines issued by the World Society of the Abdominal Compartment Syndrome (WSACS) define IAH as persistent or recurrent IAP (intra-abdominal hypertension, IAH) ≥ 12 mmHg. Abdominal compartment syndrome (ACS) should be diagnosed when IAP is consistently higher than 20 mmHg and new organ failure occurs, regardless of whether abdominal perfusion pressure (APP) < 60 mmHg occurs. IAH and ACS can cause extensive har...
