Description

A Y-shaped tube for preventing side tube clogging of double lumen peripheral catheter

technical field

The invention belongs to the medical field and relates to a Y-shaped tube for preventing side tube blockage of a double-cavity peripheral catheter.

Background technique

Peripherally inserted central catheter (PICC) is to avoid direct contact between chemotherapy drugs and arm veins. The catheter is punctured from the peripheral arm veins to the large veins close to the heart. Because the blood flow velocity of large veins is very fast Quickly dilute chemotherapy drugs to reduce the stimulation of drugs to blood vessels, so it can effectively protect upper limb veins, reduce the occurrence of phlebitis, relieve pain of patients, and improve the quality of life of patients. The operation is simple and safe, the trauma is small, and the maintenance is simple.

Although PICC is safer and more reliable than other intravenous administration methods, the double-lumen PICC tube is prone to blockage during indwelling. Fat-soluble liquids, partial drug precipitation on the PICC wall cause blockage of the catheter lumen, temporary blockage caused by particles produced by mixed use of incompatible drugs, and mechanical blockage caused by loose or improperly fixed PICC dressings .

The side tube of the double-lumen peripheral catheter is separated by a membrane. Due to the difference in personal operation, the force of the injection of the lock solution may be different during the lock, so that the pressure of the lock fluid entering the double-lumen tube is different, resulting in the deviation of the double-lumen membrane and causing the lumen Tube clogged. At present, there is no clinically indiscriminate device to prevent the side tube blockage of the peripheral catheter caused by uneven force.

Further, the bottom end of the sleeve 4 is closed and the upper end is open, and the switch 3 is inserted or screwed into the sleeve 4 through the open upper end to control the circulation or flow rate of the liquid.

Further, the switch 3 is connected to the two-way pipe 5 , and the two-way pipe 5 includes a through pipe 51 and a vertical pipe 52 . The through pipe 51 includes an inlet pipe 511 and an outlet pipe 522, the inlet pipe 511 is connected to the arm pipe of the Y-shaped body 1; the diameter of the inlet pipe 511 is smaller than the diameter of the vertical pipe 52, and the vertical pipe 52 is connected to the switch 3 match.

Further, the upper end of the vertical pipe 52 is open, and the lower end is closed.

Advantages and beneficial effects of the present invention:

The present invention has developed a Y-shaped tube for the first time to prevent the blockage of the side tube of the double-cavity peripheral catheter. The Y-shaped tube ensures the equal volume of the Y-shaped tube through the straight tube of the Y-shaped body and the connecting tube connected to the two arm tubes. pressure, thereby preventing the side tube blockage of the peripheral catheter caused by the difference in individual operation.

specific implementation

The present invention will be described in further detail below in conjunction with the accompanying drawings and examples, and the following examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

Embodiment 1 A kind of Y-shaped tube that prevents side tube blockage of double-cavity peripheral catheter

A Y-shaped tube for preventing side tube blockage of a double-lumen peripheral catheter is shown in FIG. 1 . When in use, the straight tube of the Y-shaped body 1 is connected to the syringe, and the two arm tubes are connected to the extracorporeal connector of the double-lumen PICC catheter. Through single-tube injection, the same pressure is ensured when the locking fluid is injected, which is the same as that of the Y-shaped body 1. The connecting pipe 2 connected with the two arm pipes further ensures the equal volume and equal pressure of the locking liquid. The liquid injected from the syringe flows into the double cavity through the Y-shaped tube, which ensures the equal pressure of the liquid input.

Example 2 A Y-shaped tube that prevents side tube blockage of a double-cavity peripheral catheter

A Y-shaped tube for preventing side tube blockage of a double-cavity peripheral catheter is shown in FIG. The connecting pipe 2 is connected with the two arm pipes of the Y-shaped body 1 to ensure equal volume and equal pressure of the input liquid. Sleeve 4 is located on the two arm pipes of Y-shaped body 1 and matches with switch 3. The length and diameter of sleeve 4 are larger than the diameter of the arm pipe. The flow of liquid is controlled by tightening or loosening switch 3. When in use, the straight tube of the Y-shaped tube is connected to the syringe, and through single-tube injection, the same pressure is ensured when the tube lock solution is injected. The connecting tube 2 located on the two arm tubes further ensures the same pressure.
