Problems solved by technology

[0003] 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
[0004] 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 side tube blockage of peripheral catheters caused by uneven force

Embodiment 1

[0022] Embodiment 1 A kind of Y-shaped tube that prevents side tube blockage of double-cavity peripheral catheter

[0023] A Y-shaped tube that prevents side tube blockage of a double-lumen peripheral catheter such as figure 1 As shown, it includes a Y-shaped body 1 and a communication pipe 2 , wherein the communication pipe 2 communicates with the two arm pipes of the Y-shaped body 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 liqui...

Embodiment 2

[0024] Example 2 A Y-shaped tube that prevents side tube blockage of a double-cavity peripheral catheter

[0025] A Y-shaped tube that prevents side tube blockage of a double-lumen peripheral catheter such as figure 2 As shown, it includes a Y-shaped body 1 , a connecting pipe 2 , a switch 3 and a sleeve 4 . 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 the single-tube injection ensures that the pressure of the lock solution is the same when it is injected. the same pressure.

Embodiment 3

[0026] Example 3 A Y-shaped tube to prevent side tube blockage of a double-lumen peripheral catheter

[0027] A Y-shaped tube that prevents side tube blockage of a double-lumen peripheral catheter such as image 3 As shown, it includes a Y-shaped body 1, a connecting pipe 2, a switch 3, and a two-way pipe 5. 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. Such as Figure 4 As shown, the two-way pipe 5 includes a through pipe 51 and a vertical pipe 52. The vertical pipe 51 includes an inlet pipe 511 and an outlet pipe 512. The inlet pipe 511 is connected to the two arm pipes of the Y-shaped body. The in vitro joint of the tube is connected, and the vertical tube 52 is connected with the switch 3, and the switch 3 is as Figure 5 As shown in the left figure, when the switch is closed, the section 6 formed by the inlet pipe 511 and the vertical pipe 512 is as follows: Figure 5 As ...

Abstract

The invention relates to a Y-shaped tube capable of preventing a side tube of a double-cavity peripheral catheter from being blocked. The Y-shaped tube comprises a Y-shaped body and a communicating tube. The invention also provides the Y-shaped tube which is capable of controlling liquid flow. According to the Y-shaped tube provided by the invention, injection of a tube-sealing solution can be realized through a single injection tube, and meanwhile, constant pressure and constant volume of liquid in the Y-shaped tube are ensured.

Description

technical field [0001] 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 [0002] 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. [0003] 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, par...
