Abstract
Description
Technical Field
[0001] The utility model relates to a pressure measuring device, in particular to an abdominal cavity pressure measuring device. Background Art
[0002] The incidence and mortality rate of increased intra-abdominal pressure and abdominal compartment syndrome caused by various reasons in critically ill patients are extremely high. One of the main bases for diagnosis is the increase in intra-abdominal pressure. Therefore, it is extremely important to monitor the intra-abdominal pressure in critically ill patients, which helps to detect intra-abdominal hypertension and diagnose abdominal compartment syndrome at an early stage.
[0003] The methods commonly used to measure intra-abdominal pressure include direct measurement and indirect measurement. The indirect measurement is to indirectly measure the patient's abdominal pressure through the bladder.
[0004] The principle is: the patient lies flat, and under sterile conditions, a special catheter is inserted into the bladder through the urethra. After the bladder is empty, the tee is adjusted to allow 100 ml of sterile saline to be injected into the bladder through the catheter. The catheter is then clamped, and the tee is adjusted to connect the catheter to the atmosphere. The pubic symphysis is used as the zero point, and the height of the water column is measured as the intra-abdominal pressure measurement value.
[0005] However, this water column measurement method requires connection with the atmosphere and the water column measurement catheter must be kept vertical during measurement, but this state cannot be maintained for a long time, so the pressure inside the patient's abdominal cavity cannot be continuously measured.
[0006] The existing contradiction is that high intra-abdominal pressure can cause harm to patients at any time, so if we want to avoid intra-abdominal pressure causing harm to patients, we need to continuously observe the patients. However, the water column measurement method cannot continuously observe, and the existing simple intra-abdominal pressure detection mechanism cannot continuously monitor and observe the intra-abdominal pressure of patients with behavioral ability because its water column measurement tube is open to the atmosphere and the internal liquid easily flows out after losing the restraint.
[0007] Therefore, there is an urgent need for an intra-abdominal pressure measuring device which is convenient to measure, sanitary and capable of continuously measuring the abdominal cavity pressure of the patient. Utility Model Content
[0008] The utility model aims to provide an abdominal cavity pressure measuring device, which can realize continuous observation of the abdominal cavity pressure of a patient under the premise of ensuring convenience, hygiene and safety.

DETAILED DESCRIPTION
[0038] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] like Figures 1 to 6 The abdominal pressure measuring device shown in the figure comprises a three-way adjusting disk 200, and three pipes extending along the radial direction of the three-way adjusting disk are arranged at the edge of the three-way adjusting disk, namely pipe A 210, pipe B 220 and pipe C 230. The three pipes realize the switching of the connection state between two adjacent pipes through a pivot core 600 rotatably installed in the three-way adjusting disk.
[0042] Specifically, a connecting channel 610 is provided in the pivot core 600, and the two ends of the connecting channel extend to the side wall of the pivot core respectively to realize the through-arrangement in the pivot core. At the same time, the angle between the two ports of the connecting channel is the angle between two adjacent pipes, so as to ensure that after one end of the connecting channel is connected to the inner end of one of the pipes, the other end is connected to the inner end of the adjacent pipe. Specifically, the connection mode of the three pipes through the pivot core can be that pipe A is connected to pipe B, or pipe B is connected to pipe C.
[0043] In addition, if Figure 1 As shown, a pressure gauge 400 is connected to the outer end of pipe C. When pipe B is connected to pipe C, the liquid in the bladder is discharged and enters the pressure gauge through pipe B and pipe C to act on the pressure gauge. After the pressure gauge is acted on, the corresponding pressure value in the patient's abdominal cavity is measured, thereby realizing continuous monitoring of the patient's abdominal cavity pressure.
[0044] It should be noted that, in order to facilitate the discharge of liquid (saline or a mixture of saline and urine) in the bladder, a urethral catheter 300 is detachably connected to the outer end of the pipe B, and the urethral catheter is inserted into the patient's bladder when detecting the abdominal pressure.
[0045] As the input port and the discharge port of the pressure transmission medium, a drainage bag 100 or a syringe 800 is connected to the outer end of the pipe A. Specifically, when it is necessary to input the measurement medium as the reference pressure, the syringe is connected to inject about 100 ml of physiological saline into the bladder, and when the patient needs to discharge urine, the drainage bag is connected.
[0046] In addition, a vent cap 240 connected to the pipeline C is provided on the outer wall of the pipeline C, and the air in the pipeline is discharged when the pressure is measured by loosening the vent cap. It should be noted that the vent cap can be completely unscrewed, so that a needle can be inserted into the pipeline C after the vent cap is unscrewed to perform more efficient suction and exhaust.
[0047] Working Principle: When continuous monitoring of the patient's abdominal pressure is required, medical staff follow the steps below.
[0048] 1. Turn the pivot to connect pipe A and pipe B.
[0049] 2. Connect a drainage bag to tube A, insert a urinary catheter into the patient's bladder, and connect the urinary catheter to tube B.
[0050] 3. Drain the urine from the patient's bladder into the drainage bag.
[0051] 4. Remove the drainage bag, then insert a syringe containing at least 100 ml of saline into tube A and inject 100 ml of saline into the bladder.
[0052] 5. Rotate the pivot core to connect pipes B and C. At this time, pipe A is in a closed state;
[0053] 6. The saline in the bladder enters the pressure gauge through the catheter, pipe B, connecting channel, and pipe C. The saline then applies pressure to the pressure gauge. The measured pressure is the patient's real-time abdominal pressure.
[0054] 7. Record the measured pressure value, then hang the three-way adjustment dial on the patient's waist and abdomen at the same height as the bladder, and then adjust the pressure gauge value to the measured value again. This will enable real-time observation of the patient's abdominal pressure.
[0055] It should be noted that in order to avoid the contamination of the pressure gauge, the pressure gauge can be recycled. A piston 500 is also slidably provided in the pipe C. At the same time, a sealing sheet 700 is sealed on the outer end port of the pipe C. The sealing sheet and the piston cooperate with the pipe C to form a sealed cavity, in which physiological saline is sealed. In coordination with this, an axially extending puncture tube 410 is provided in the connecting end of the pressure gauge. Specifically, when the pressure gauge is connected to the pipe C, the puncture tube punctures the sealing sheet at the same time, so that the physiological saline in the sealed cavity can smoothly enter the Bourdon tube of the pressure gauge when the piston is pressurized. At the same time, it should be noted that due to the obstruction of the piston, the liquid discharged from the patient's bladder cannot enter the Bourdon tube through the piston, thereby ensuring the hygiene and safety of the pressure gauge.
[0056] It should also be noted that, in the above embodiment, in order to prevent the punctured portion of the sealing sheet from being separated from the sealing sheet and entering the Bourdon tube of the pressure gauge 400, the puncture tube 410 specifically includes a tube body 411 connected to the liquid inlet end of the pressure gauge, and the front end of the tube body has a sharp portion 412 with an inclined surface. Specifically, when the pressure gauge is connected to the tube to C, half of the sharp portion punctures the sealing sheet, and at this time, the portion of the sealing sheet that is not punctured by the sharp portion is still connected to the sealing sheet body, thereby preventing the portion from subsequently separating from the sealing sheet body and entering the pressure gauge.
[0057] It should be noted that, in order to achieve accurate docking between the pipeline and the connecting channel during switching, a bend plate 620 is also provided on the pivot core 600. Specifically, an arrow 630 is also provided on the bend plate, and the arrow points to one of the ports 630 of the connecting channel.
[0058] It should also be noted that, in order to facilitate the connection between the syringe 800 and the pipe A, the channel of the pipe A is a tapered channel, specifically, the diameter of the channel of the pipe A gradually decreases from the outer end to the inner end. Then, the syringe can be inserted into the pipe A conveniently and tightly.
[0059] In addition, in order to facilitate the fixation of the three-way adjustment disk 200 on the patient and to facilitate carrying when walking outside, an elastic clamping plate 250 is also provided on the back of the three-way adjustment disk. When the patient needs to go out, the three-way adjustment disk can be attached to the patient's abdominal belt through the elastic clamping plate. At this time, it should be noted that the pressure gauge and the patient's bladder should be at the same height as much as possible to ensure the accuracy of the measurement.
[0060] Finally, in order to facilitate the identification of the plug-in positions of the drainage bag 100, the urinary catheter 300, the pressure gauge 400 and the syringe 800 during use, an indication sign 260 is also provided on the surface of the three-way adjustment disk 200. Specifically, the indication sign at the pipe A is "water inlet / drainage bag interface", the indication sign at the pipe B is "urinary catheter interface", and the indication sign at the pipe C is "pressure gauge interface".
[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
