Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a right heart floating catheter zero point measuring instrument. Background Art

[0002] The right heart floating catheter is used to assess cardiovascular function, mainly through the balloon and blood circulation. When using the right heart floating catheter, the patient's zero point needs to be measured. The traditional right heart floating catheter zero point measurement steps are cumbersome, and there is no corresponding measurement tool. It is necessary to use a level ruler and an angle ruler for measurement.

[0003] The existing measurement steps are: the patient is in a supine position, and then the level ruler is placed at the level of the patient's fourth intercostal space to ensure that the three horizontal points are always in a horizontal position when the level ruler is used. At this time, one person needs to be placed on the patient's head to measure and ensure the balance of the level ruler;

[0004] Then place the angle ruler parallel to the examination bed, and make the other side of the angle ruler against the patient's left chest wall and one side of the level ruler. At this time, a second person is required to cooperate;

[0005] Then read the scale of the horizontal ruler on the angle ruler, which is the thorax thickness A. Divide the thorax thickness by 2, that is, A / 2cm. At the same time, mark this position on the patient's chest with a marker.

[0006] Finally, the first operator takes down the level ruler and places the upper edge (or lower edge) of one end of the level ruler parallel to the mark point. The second operator places the other end of the level ruler level with the tee of the pressure sensor. At this time, the zero point position is confirmed, and the pressure sensor is connected to the machine measurement module to perform the zero adjustment setting.

[0007] It can be seen that the traditional right heart floating catheter zero point measurement steps are complicated and there is no corresponding measurement tool. It needs to use a level ruler and an angle ruler to perform the measurement operation. At the same time, it requires two people to cooperate to complete it.

The outer side of the measuring ruler 1 is provided with scale lines 5, and the scale lines 5 can be used to quickly measure the chest thickness of the patient.

[0036] The level ruler 3 and the horizontal pointer 4 both slide on the outside of the measuring ruler 1. The sliding of the level ruler 3 can locate the patient's chest thickness, and the sliding of the horizontal pointer 4 can locate the position of half of the patient's chest thickness. The level ruler 3 and the horizontal pointer 4 are parallel to the bottom ruler 2. A level meter is provided on the top of the bottom ruler 2, the level ruler 3 and the horizontal pointer 4. The level meter can help medical staff observe whether the equipment is level, thereby improving the accuracy of measurement.

Then, tighten the fastening screw 9 at one end of the level ruler 3 to fix it at the current position. At this time, read the scale position at the bottom of the level ruler 3 through the scale line 5 and record it as A. At the same time, calculate A / 2.

[0042] And by loosening the fastening screw 9 at one end of the horizontal pointer 4, adjust the bottom of the horizontal pointer 4 to the A / 2 position, and then tighten the fastening screw 9 at one end of the horizontal pointer 4 to fix it at the current position;

[0043] At the same time, make the end of the horizontal pointer 4 away from the measuring ruler 1 level with the three-way of the pressure sensor. At this time, the zero point position is confirmed, and the pressure sensor is connected to the machine measurement module to perform zero adjustment setting.
