Description

Devices for measuring central venous pressure

Technical Field

The utility model relates to the field of clinical venous pressure auxiliary measurement and provides a device for measuring central venous pressure.

Background technique

In clinical practice, a central venous catheter is often placed in the patient to monitor the patient's cardiac function and blood volume. The catheter is placed through the superior and inferior vena cava or right atrium to facilitate clinical medical staff to monitor the patient's hemodynamics. Central venous pressure refers to the average blood pressure entering the right atrium.

At present, it is generally measured through a central venous pressure measuring tube. Nurses use two rulers to measure it. The central venous pressure is mainly obtained by the height of the physiological saline in the central venous pressure measuring tube. The zero scale of the central venous pressure measuring tube needs to be compared with the patient's mid-axillary line. This makes the nurses have problems of inconvenience and low efficiency in the actual operation.

In this process, the medical staff does not need to hold the bracket 100, and only needs to adjust the level ruler 102 to align it with the mid-axillary line of the subject. At this time, the corresponding position of the level ruler 102 is the center zero point, and the corresponding central venous pressure can be calculated based on the scale value corresponding to the water column on the sleeve 106, thereby completing the accurate measurement of the subject.

Please continue to refer to Figures 1 and 2. In the embodiment of the utility model, the support 100 is used to support the level 102, and scale lines are set along the height direction of the sliding sleeve 106. By adjusting the relative position of the level 102 and the support 100, the height of the level 102 can be adjusted. When the level 102 points to the mid-axillary line of the subject, it is convenient for medical staff to calculate the central venous pressure of the subject according to the scale on the sliding sleeve 106.

As shown in FIG. 1 , in the embodiment of the utility model, in order to facilitate hanging of the fluid bag, a hook 118 is further provided on the top of the bracket 100 , which makes it convenient for medical staff to hang the fluid bag that needs to be provided to the subject on the hook 118 during actual use.

It should be noted that, in the embodiment of the utility model, in order to ensure the horizontality of the level ruler 102, a limiter 116 is provided on the sleeve 106. That is, when the level ruler 102 is in an open state relative to the bracket 100, in order to ensure that the angle between the level ruler 102 and the bracket 100 is 90 degrees, a limiter can be provided on the sleeve 106 at a position corresponding to the hinge hole 112, and when the level ruler 102 is fully opened, the level ruler 102 can be ensured to be in a horizontal state by the limiter.

According to an embodiment of the present invention, the level ruler 102 includes a plurality of ruler tubes which are sleeved in sequence, and a stopper is suitable for passing between two adjacent ruler tubes.
