Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a bladder pressure measurement auxiliary device. Background Art

[0002] Intra-abdominal pressure, referred to as intra-abdominal pressure, refers to the abdominal pressure around the bladder. Cystometry is a simple and practical reliable method for quantitatively monitoring intra-abdominal pressure. Purpose of cystometry: To monitor intervention treatment and nursing, timely detect intra-abdominal high pressure, prevent the development and occurrence of abdominal interstitial syndrome, and reduce the mortality rate of patients. Method for measuring intra-bladder pressure: Place a double-lumen balloon urinary catheter (catheter) in the patient's body; connect a three-way tube at the opening of the catheter, and the other two ports of the three-way tube are connected to the urine bag and the homemade pressure measuring tube respectively; the catheter needs to be disinfected after opening to ensure aseptic operation.

[0003] Operation steps: 1. The patient should lie in supine position with the abdominal muscles relaxed; 2. Open the catheter opening to empty the urine in the bladder; 3. Inject normal saline into the catheter with a syringe; 4. 30 seconds after the bladder is filled with water, observe the homemade pressure measuring tube and measure the height of the water column with a tape measure to calculate the intra-abdominal pressure.

[0004] The shortcomings of the above technologies are:

[0005] 1. Since the existing three-way pipe port and the catheter tube port cannot be directly connected, an extension tube needs to be connected between the two for drainage, which takes up a large space and is inconvenient to place.

[0006] 2. In the traditional method of measuring bladder pressure, medical staff need to place a homemade pressure measuring tube vertically and manually measure the height of the water column with a tape measure. This operation is difficult for one person to complete, and the measurement and calculation are prone to errors. Utility Model Content

[0007] The utility model aims to provide a bladder pressure measurement auxiliary device, which is connected to the catheter tube port, occupies less space and is easy to place; when measuring intra-abdominal pressure, it can automatically display the pressure value, improve the accuracy of intra-abdominal pressure measurement, and reduce the work intensity of medical staff.

[0008] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0009] A bladder pressure measurement auxiliary device includes a pressure indicator. The outer surface of the pressure indicator is provided with a pressure measuring joint for connecting to a urinary catheter, a urination joint for connecting to a urine bag, and a liquid injection joint for connecting to a syringe. The pressure measuring joints are connected to the urination joint and the liquid injection joint respectively. A pressure sensor is provided in the pressure measuring joint, and the pressure sensor is electrically connected to the display screen of the pressure indicator. The outer end of the pressure measuring joint is in the shape of a hollow topless cone.

A pressure sensor is arranged inside the pressure measuring joint 11, and the pressure sensor is electrically connected to the display screen of the pressure indicator 1. The outer end of the pressure measuring joint 11 is in the shape of a hollow topless cone. The outer end of the pressure measuring joint 11 is inserted into the tube mouth of the urinary catheter 31 for fixation. A locking piece 2 is sleeved on the outer side of the pressure measuring joint 11. The urination joint 12 adopts a hose, and a stop valve is arranged inside the urination joint 12.

The liquid injection joint 13 adopts a positive pressure joint, and the nozzle of the injector 33 is inserted into the liquid injection joint 13 for fixation. The medical staff inserts the pressure measuring connector 11 into the tube mouth of the urinary catheter 31, and then clamps the tube mouth of the urinary catheter 31 with the locking piece 2, so that the pressure indicator 1 is fixed to the urinary catheter 31. Before measuring the intra-abdominal pressure, the medical staff inserts the pagoda head of the urine bag 32 into the urination connector 12, and then uses the control button 14 to open the stop valve, empty the urine in the bladder and collect the urine into the urine bag 32; when measuring the intra-abdominal pressure, the medical staff uses the control button 14 to close the stop valve, block the connection between the urination connector 12 and the pressure measuring connector 11, and then inserts the nozzle of the push injector 33 into the injection connector 13 and injects physiological saline into the bladder.
