CN201046117Y - Central Venous Pressure Manometry Device - Google Patents

Abstract

A central venous pressure measuring device belongs to medical monitoring equipment. It mainly solves the shortcomings of the existing central venous pressure measurement methods, such as cumbersome device installation, complicated operation, and the fact that the whole device cannot be moved at any time with the change of the patient's body position. The utility model comprises a three-way joint with a switch, a measuring tube marked with a scale line and an infusion tube, wherein two ports in the three-way joint are respectively connected with the measuring tube and the infusion tube. The utility model has the advantages of simple structure and convenient installation.

Description

Central Venous Pressure Manometry Device

technical field

The utility model belongs to medical monitoring equipment.

Background technique

Central venous pressure refers to the pressure in the superior and inferior vena cava or the right atrium in the thoracic cavity. Its monitoring is widely used in clinical practice. Cardiac output syndrome, open-heart surgery under extracorporeal circulation, and other critically ill patients, such as severe pancreatitis, major trauma, burns, major infections, and monitoring of major operations, such as pancreas twelve Intestinal resection, liver transplantation, heart-lung transplantation, etc. It is one of the basic indicators for clinical monitoring of blood volume and right heart function, and can reflect the comprehensive status of cardiac output function, blood volume and vascular tension. The existing measurement method is to fix the scale and the infusion set together on the saline stand with adhesive plaster, and then use the three-way switch to connect with the venous infusion set and the central venous puncture catheter for monitoring. There are the following disadvantages: 1) The device is cumbersome to install and the operation is complicated; 2) The zero scale of the ruler must be aligned with the patient's midaxillary line during measurement. When the patient changes position, the whole device not only needs to be readjusted, but also is prone to errors; 3) The open infusion set does not have any protection or filtering device, and directly communicates with the outside world, which violates the principle of sterility.

Contents of the invention

The purpose of this utility model is to provide a central venous pressure manometry device which is simple in structure, easy to install, and can be moved at any time according to the patient's body position.

The utility model is realized in the following way: it comprises a three-way joint with a switch, a measuring tube marked with a scale line and an infusion tube, wherein two ports in the three-way joint are respectively connected with the measuring tube and the infusion tube.

The upper end of the measuring tube is also provided with a top cover.

The utility model directly marks the scale line on the measuring tube, and connects the measuring tube and the infusion tube through the three-way joint. When installing, you only need to fix the measuring tube. The structure is simple and easy to install, and it can be moved at any time with the change of the patient's position. There is no need to readjust the whole device, so as to avoid errors; when no measurement is needed, it can be moved The top cover of the measuring tube is closed to reduce the chance of bacterial contamination.

Description of drawings

The accompanying drawing is a schematic diagram of the structure and use state of the utility model, 1--switch, 2--tee joint, 3--measurement tube, 4--transfusion tube, 5--top cover, 6--central venous puncture catheter, 7--Intravenous infusion set.

Detailed ways

Further illustrate the utility model below in conjunction with accompanying drawing and embodiment.

Embodiment: the three-way joint 2 has a switch 1, and the measuring tube 3 and the infusion tube 4 are hard and transparent plastic tubes. Wherein, the tube body of the measuring tube 3 is marked with a standard scale from 0-30cm, and the upper end is provided with Top cover 5, assembles each parts by aforesaid mode and promptly becomes the utility model.

The measurement method is: connect the infusion tube 4 with the central venous catheter 6, connect the other port of the three-way joint 2 with the venous infusion set 7, close the infusion tube 4 through the switch 1, and fill the venous infusion set 7 with physiological saline Measuring tube 3, align the zero scale of measuring tube 3 with the right atrium level of the patient's midaxillary line, close the venous infusion set 7, and open the infusion tube 4 to measure the central venous pressure.

Claims (2)
