Description

Isovolumetric Isobaric Sealer for Double Lumen PICC Catheters

technical field

The utility model belongs to the field of medicine and relates to an isovolumic and isobaric tube sealer for a double-cavity PICC catheter.

Background technique

Peripherally inserted central catheter (PICC) is widely used in cancer patients because of its safety and reliability, high puncture success rate and long indwelling time. The PICC catheter can be inserted into the catheter at one time, and can be administered simultaneously in two channels, reflecting the advantages of the "one-needle" intravenous therapy of the PICC catheter. In addition to being used for general venous treatment, it also has the functions of monitoring central venous pressure, high-pressure injection of contrast agent, etc., which meets the needs of patient treatment and examination.

Although PICC is safer and more reliable than other intravenous administration methods, the double-lumen PICC tube is prone to blockage during indwelling. Non-coagulable blockage caused by contraindicated drugs or macromolecular drugs with high viscosity and easy crystallization, and mechanical blockage caused by loose or improperly fixed PICC dressings.

The double lumen of the PICC is separated by a membrane. Two syringes are used to inject the locking solution to seal the tube. Due to the difference in personal operation, the force of injecting the locking solution may be different, so that the pressure of the locking solution entering the double lumen tube is different, resulting in double The displacement of the luminal membrane leads to occlusion of the lumen. At present, there is no effective device to prevent pipeline blockage 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.

Advantage and beneficial effect of the utility model:

The utility model firstly develops a double-cavity PICC catheter isobaric isobaric sealer. The sealer ensures the equal volume of the sealer through the straight pipe of the Y-shaped body and the connecting pipe connected to the side wall. pressure, thereby preventing the clogging of the double lumen tube caused by the difference in individual operation.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments are only used to illustrate the utility model and not to limit the scope of the utility model.

Embodiment 1 A kind of isovolumic and isobaric tube sealer for double-lumen PICC catheter

An isovolumic and isobaric sealer for a double-lumen PICC catheter is shown in FIG. 1 , which includes a Y-shaped body 1 and a connecting tube 2 , wherein the connecting tube 2 communicates with the two arm tubes 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 liquid input.

Embodiment 2 The isovolumic and isobaric tube sealer of the double-lumen PICC catheter

An isovolumic and isobaric sealer for a double-lumen PICC 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 the single-tube injection ensures that the pressure of the lock solution is the same when it is injected. the same pressure.
