Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an abdominal cavity external drainage device capable of conveniently measuring intra-abdominal pressure.
Background
Intra-abdominal pressure (intra-abdominal pressure, IAP) is simply referred to as intra-abdominal pressure, and refers to the steady state pressure sealed within the abdominal cavity. Its normal value is generally 5-7mmHg, and IAP can be increased under pathological conditions such as wound, abdominal hemorrhage, tumor, gestation, ascites due to liver cirrhosis, etc. When IAP continues beyond 20mmHg, perfusion of organs in the abdominal cavity may be affected, resulting in severe abdominal compartment syndrome. IAP is therefore an important monitoring indicator for patients in the surgical phase and in critically ill patients.
The IAP measurement methods can be classified into direct measurement methods and indirect measurement methods. Currently, indirect measurement methods, i.e. measurement of IAP via urinary catheters, intragastric catheters, intracolonic catheters or inferior vena cava catheters, are mainly used clinically. The walls of these hollow organs and the blood vessel walls act as pressure-conducting membranes during measurement, and thus intra-luminal pressure can indirectly reflect changes in IAP. The direct measurement method needs to directly penetrate into the abdominal cavity through a puncture needle, and the outside is connected with a pressure measuring tube or a pressure sensor to obtain a measurement result. Compared with the indirect measurement method, the method has more accurate measurement results, but is not generally used clinically because the method belongs to invasive operation, the risks of infection, bleeding and the like are possibly increased, and the technical requirements of the puncture operation on operators are higher.
However, in specific groups, such as patients with abdominal drainage tubes placed after surgery, or patients with a puncture and tube placed in the abdominal cavity in an inpatient ward and an ICU, the pressure measurement can be performed without additional puncture operation by the patient with an abdominal catheter. Compared with an indirect pressure measurement method, the method is simpler and more convenient to operate and more accurate in measured value. However, the existing external drainage device of the abdominal cavity drainage tube has no pressure measuring function. During measurement, the abdominal cavity drainage tube is separated from the drainage bag, and then the pressure value is obtained by two methods. First, the outside head end of drainage tube connects a pressure measuring tube in addition, is fixed in the infusion support with pressure measuring tube perpendicular to ground direction, and then uses the long chi to measure drainage liquid water column height. The operation is complicated, and the pressure value obtained is expressed in centimeters of water (cmH) 2 O) is manually converted into internationally recognized millimeter Hg (mmHg) unit value. Second, as with indirect measurement, the external head end of the drainage tube is connected with a pressure sensor, and then connected with the monitoring equipment through the pressure sensor. This method requires a special transducer, is expensive, requires monitoring equipment, and is not suitable for general ward.
The current product is mainly used for indirect IAP measurement, taking the measurement of bladder pressure through a catheter as an example to indirectly reflect IAP, and comprises the following operation steps:
(1) The sensor transducer is connected and the sensor is placed on the axillary midline to be zeroed.
(2) Clamp a Foley catheter inserted into the patient's bladder.
(3) Up to 25mL of saline was instilled into the bladder through the suction port of the Foley catheter and the tube was filled with fluid.
(4) An 18G needle connected to a pressure sensor is inserted into the suction port of the catheter (which can also be done with some new catheters, which have needleless connection systems).
(5) Readings were taken at supine position, end-tidal, abdominal muscle relaxation.
The defects are that:
(1) Special pressure transduction devices are required and the consumables are relatively expensive.
(2) The monitoring instrument needs to be connected, has certain condition limitation, and is not suitable for the general ward.
(3) The IAP is indirectly reacted through the bladder pressure, so that the IAP is easily interfered by various clinical factors and has lower accuracy compared with a direct pressure measurement method.
(4) The operation is still relatively complex, and the connecting pipelines are more.
