Description

Technical Field

[0001] The utility model relates to the technical field of flushing devices, in particular to a disposable medical PICC catheter double-tube flushing device. Background Art

[0002] Medical PICC catheters are also known as peripherally inserted central venous catheters, which are usually used for puncture in the peripheral veins outside the patient's body. PICC catheters need regular maintenance during use and need to be flushed with flushing fluid to ensure that the catheter is unobstructed. In view of this, traditional devices are not perfect and do not have facilities for storing hoses. The disposable medical PICC catheter double-tube flushing device can provide convenience for staff.

[0003] Patent document: JP4710280B2, discloses a flushing device and a catheter kit. The flushing device and catheter kit disclosed above mainly consider the problem of how to flush the catheter with a guide wire inserted into the catheter when using a common torque device, but do not consider the problem of facilitating the storage of the hose.

[0004] Existing medical PICC catheter double-tube flushing devices usually pull the skin and flesh at the puncture site of the patient during use, causing pain to the patient. For this reason, the length of the hose is increased to facilitate flushing. The longer hose is not easy to store, which reduces practicality. Utility Model Content

[0028] See also Figure 1 , Figure 2 and Figure 3, a disposable medical PICC catheter double-tube flushing device, including a circular plate 9, and the circular plate 9 is located on the front of the flushing box 1, the circular plate 9 is located on the outside of the hose 5, a center rod 10 is installed on the front of the circular plate 9, and another circular plate 9 is installed at one end of the center rod 10, the flushing box 1 can provide a stable support for the center rod 10, and the center rod 10 can provide a winding support for the hose 5, and an annular slide groove 11 is opened on the side where the two circular plates 9 are close to each other, and a sliding ring 12 is placed on the inner side of the slide groove 11, and a ring plate 13 is installed between the two sliding rings 12, the circular plate 9 can provide an opening space for the slide groove 11, and the slide groove 11 can provide a movable space for the sliding ring 12, and the slide groove 11 cooperates with the sliding ring 12 to facilitate the rotation of the ring plate 13, and a circular hole 15 is opened inside the ring plate 13, and the circular hole 15 is located on the outside of the hose 5, and a plurality of protrusions 14 are installed on the outside of the ring plate 13, and the protrusion 14 can increase friction to facilitate the rotation of the ring plate 13.

[0029] After flushing, the staff grabs the ring plate 13 and rotates it, using the raised part of the protrusion 14 to increase the friction with the fingers to rotate the ring plate 13, and the ring plate 13 drives the sliding ring 12 to rotate, so that the sliding ring 12 rotates along the inner side of the slide groove 11, and the rotation of the ring plate 13 drives the circular hole 15 to rotate, and the circular hole 15 drives the hose 5 to rotate, so that the hose 5 rotates and winds along the center rod 10 as the center of the circle, and the hose 5 is wound between the two circular plates 9, so that the hose 5 is convenient for storage.

[0030] See also Figure 1 , Figure 4 and Figure 5 A disposable medical PICC catheter double-tube flushing device includes a scale 16, and the scale 16 is engraved on one side of the flushing box 1. A glass column 17 is installed on one side of the flushing box 1. A column groove 19 is opened on the inner side of the glass column 17. A through hole 18 is opened on the inner side of the glass column 17, and the through hole 18 is connected with the liquid storage tank 2 and the column groove 19 respectively. The glass column 17 can provide a space for the through hole 18 to make the water level inside the column groove 19 consistent with the water level inside the liquid storage tank 2. A floating plate 20 is placed on the inner side of the column groove 19, and a marking layer 21 is applied on one side of the floating plate 20. The floating plate 20 can float on the top of the flushing liquid by its own buoyancy. The marking layer 21 is a conspicuous color different from that of the floating plate 20, which is convenient for distinguishing the position of the water level.

[0031] When the staff uses the micro pump 7 to extract the flushing liquid, the water level of the flushing liquid inside the liquid storage tank 2 drops accordingly, and the through hole 18 connects the column groove 19 with the liquid storage tank 2, so that the water level inside the column groove 19 drops, and at the same time, the floating plate 20 moves downward with the water level inside the column groove 19. The column groove 19 provides a guide for the floating plate 20, so that the floating plate 20 moves downward along the inside of the column groove 19. The staff penetrates the inside of the glass column 17 from the outside, so that the line of sight can see the position of the marking layer 21 through the glass. Because the color of the marking layer 21 is different from that of the floating plate 20, the position of the marking layer 21 can be clearly seen. Through the correspondence between the marking layer 21 and the scale 16 on one side, the amount of flushing liquid inside the liquid storage tank 2 can be clearly grasped, and the amount of flushing liquid used for flushing can be conveniently controlled.

[0032] Working principle: Before using the device, check whether there are any problems that affect its use. When the staff needs to use the device, they should first inject flushing liquid into the inner side of the liquid storage tank 2. The flushing liquid drives the floating plate 20 to float. Through the marking layer 21 and the corresponding scale 16, inject an appropriate amount of flushing liquid, connect the flushing tube 8 with the medical PICC catheter double tube for flushing. After the flushing is completed, grab the ring plate 13 and rotate it to store the hose 5 between the two circular plates 9.
