Embodiment 1

[0027] A central venous head positioning electrocardiographic guidance can be conducted infusion set, such as figure 1 and figure 2 As shown, the infusion tube 1 is included, the end of the infusion tube 1 is provided with a vent hole 10, the dropper 2 is installed on the infusion tube 1, and the position of the infusion tube 1 close to the other end is provided with a protective sleeve 3, inside the protective sleeve 3 An internal thread 30 is provided, a first external thread 11 is provided on the infusion tube 1 on one side of the protective sleeve 3, a second external thread 12 is provided at a position corresponding to the protective cover 3 on the infusion tube 1, and the other end of the infusion tube 1 is installed With luer connector4.

[0028] In this embodiment, the dropper 2 is connected with the infusion tube 1, and the dropper 2 and the infusion tube 1 adopt an integrated structure to ensure the tightness of the connection between the infusion tube 1 and the dr...

Embodiment 2

[0034] As a second embodiment of the present invention, in order to prevent the thickness of the connecting wire 6 from directly affecting the clarity of the P wave amplitude of the electrocardiogram and the accuracy of the precise positioning of the catheter, the inventor made improvements to the infusion tube 1 as a preferred Examples such as Figure 3-5 As shown, the infusion tube 1 corresponding to the second external thread 12 is made of stainless steel.

[0035] In this embodiment, the stainless steel has bright color and good corrosion resistance, which is beneficial to increase the service life.

[0036] Furthermore, since human tissue is a volume conductor, ECG signals can be transmitted to all parts of the body. Not only the electrical signals of the heart itself can be measured by cardiac electrodes, but also can be measured by body surface electrodes. Electrodes RA and LA are the main extraction of ECG signals. The point is also the signal source of the intracavit...

Embodiment 3

[0041] As a third embodiment of the present invention, in order to facilitate the use of medical personnel, the end of the inventor's infusion tube 1 is improved. As a preferred embodiment, the vent hole 10 is equipped with a hole cap 5, and the hole cap 5 is connected with the A connection line 6 is provided between the infusion tubes 1 .

[0042] In this embodiment, the hole cap 5 and the connecting wire 6 adopt an integrated structure to ensure the stability of the connection between the hole cap 5 and the connecting wire 6 .

[0043] Specifically, the hole cap 5 is plugged and matched with the vent hole 10. When the vent hole 10 needs to be opened, the hole cap 5 can be separated from the vent hole 10 to realize that the vent hole 10 is opened. When closing, the hole cap 5 and get final product embedded in the air vent 10.

[0044] When the central venous head end positioning electrocardiogram guiding transmissible infusion set of the present invention is in use, through ...

Abstract

The invention relates to the technical field of infusion sets, in particular to a conductive infusion set guided by central vein headend positioning electrocardio. The infusion set comprises an infusion pipe, wherein an exhaust hole is formed in the end of the infusion pipe; a hole cap is arranged on the exhaust hole, and a dropper is mounted on the infusion pipe; a protecting sleeve is arranged at the position close to the other end, of the infusion pipe in a sleeving manner; an internal thread is formed in the protecting sleeve; and a Luer fitting is mounted at the other end of the infusionpipe. Through a second external thread which is formed, on one hand, the protecting sleeve is prevented from sliding off, and on the other hand, a common syringe needle can be replaced to be connectedwith a heparin cap so as to be directly connected with a metal clip. Normal saline is used for dripping to lead out an electrocardiogram P-wave amplitude in a cavity. Because the second external thread is thicker than the syringe needle, and the connection stability with the metal clip is higher, the guided P-wave amplitude is stabler, and improvement of the accuracy of accurate positioning of aduct is facilitated.

Description

technical field [0001] The invention relates to the technical field of infusion sets, in particular to a central vein head-end positioning electrocardiogram-guided conduction infusion set. Background technique [0002] Central venous catheters are now widely used in clinical practice. Using intracavitary electrogram (ECG) positioning technology to judge the position of the catheter tip by using the P wave shape changes when the catheter arrives at different positions in the superior vena cava cavity is timely, safe and accurate. Some studies have applied continuous infusion of normal saline to three-way valve type PICC, CVC and intracavitary ECG guidance of infusion ports for positioning. At present, the electrocardiographic positioning method is used to connect the metal clip of the lead wire to the end of the guide wire in the PICC catheter or the needle tip of the infusion set to the CVC, and the Luer connector at the head end of the infusion port catheter to guide the ch...
