Description

Disposable simple device for manually measuring central venous pressure

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to a disposable simple device for manually measuring central venous pressure.

Background

Venous transfusion is the most widely used treatment method in clinical treatment, the security of transfusion system is the problem of paying more attention to in the current clinical use, medical personnel must can use after discharging the gas in dropping funnel and the infusion pipeline when infusing, even so, in case medical personnel negligence comes not too late to change new liquid, can cause the liquid evacuation, behind the pipeline below the air admission dropping funnel, can form the big section bubble, perhaps appear serious blood return phenomenon, above these problems all can lead to the fact very big security threat for the infusion patient. The use of infusion sets is also commonly used for the detection of central venous pressure, which refers to the pressure in the right atrium and the thoracic segments of the superior and inferior vena cava. The comprehensive condition of the blood volume, the cardiac function and the vascular tension of the patient can be judged, and the comprehensive condition is different from the peripheral venous pressure and is widely applied to the detection of clinical treatment;

there is certain drawback when using in current transfusion system, at first, current transfusion system does not mostly take the scale mark, need carry out CVP's detection with the help of the ruler, even take the scale also not zero scale mark have numerical value from top to bottom, secondly, current transfer line need prop the transfer line with both hands when carrying out measurement center venous pressure, prop up one by one, and it is extremely inconvenient to use, can't liberate the hand.

The blood pressure of the right atrium and the big thoracic vein is generally called central venous pressure, and the following two methods are used in the existing medical institution to measure the central venous pressure:

one of the methods is to connect the deep venous catheter with a transducer in a monitor, and directly measure the central venous pressure on the monitor, and although the method is safe and reliable and accurate in measurement, the transducer is required, and the measurement cost is high.

The other method is a currently common simple method, namely, the infusion tube is pulled out from the infusion bag to be communicated with the atmosphere during pressure measurement, then when the height of a water column in the infusion tube is stable, the crossing point of the axillary midline and the fourth rib is taken as a zero point, the height of the water column is measured, and the central venous pressure is expressed by X cm water column. The measuring method is accurate, the measuring cost is low, the operation is convenient and easy, however, the infusion tube is pulled down from the infusion bag to measure the central venous pressure and then is inserted again, the infusion tube is pulled down from the infusion bag to be communicated with the atmosphere, the pollution to the upper end of the infusion tube is often caused, and the sanitary requirement cannot be met.
