Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a PICC pipeline maintenance tracking and reminding device. BACKGROUND

[0002] The PICC pipeline is a central venous catheter that is placed in the superior vena cava or the superior vena cava through peripheral venipuncture, which provides a long-term safe intravenous infusion channel for patients, and can be used for infusion of various drugs, nutrient solutions and blood products, etc. After the PICC pipeline is placed, it can be left for six months to one year. The patient routinely changes the adhesive film and flushes the sealing tube once every 7 days during the non-infusion period. The medical staff needs to observe whether the skin around the puncture point is red, swollen and exudes liquid, etc. in daily nursing. Using the PICC can avoid the damage to the blood vessels caused by the long-term infusion of patients facing irritating drugs, and reduce the pain brought to the patients by repeated puncture.

[0003] The most common way of adjusting the flow rate of the PICC pipeline is the manual flow rate regulator, but this way is one of the most prone to problems in pipeline adjustment. If the pipeline flow rate is too high, it will cause irritation and damage to the blood vessels, and the patient will feel pain, swelling and fever, etc. Therefore, it is necessary to set up secondary flow limiting for the pipeline flow rate and detect the pipeline flow condition, which has a positive significance for pipeline maintenance and can remind medical staff to pay attention to the pipeline retention time and observe the pipeline and the surrounding skin.

[0025] The present application will be further described below in combination with the embodiments.

[0026] Embodiment:

[0027] Reference Figures 1 to 6 ​The utility model provides a kind of PICC pipeline maintenance tracking and reminding device, including infusion tube 1 and silica gel patch 2, the upper part of silica gel patch 2 is fixedly provided with regulator 3, silica gel patch 2 is installed position as double-sided paste film, to paste in the position close to internal jugular vein or femoral vein etc.

[0028] The inner surface of the upper part of the fixing base 11 is rotationally connected with a rotating shaft 13, one side of the rotating shaft 13 is fixedly provided with a clamping piece 14, the clamping piece 14 is inserted into the inner surface of the clamping groove 12, the opening size of the clamping groove 12 is greater than that of the clamping piece 14, and the gap between the clamping groove 12 and the clamping piece 14 is about 0.3 mm; the length and width of the clamping groove 12 are set to be large to provide a position gap for the insertion of the clamping piece 14, so that the clamping piece 14 can smoothly penetrate through the clamping grooves 12 at different positions of the belt 10, and the belt 10 is prevented from excessively shaking during the stretching process due to the too large gap; the other side of the rotating shaft 13 is fixedly provided with a pressing cover 15, the lower end of the clamping piece 14 is fixedly connected with a spring 16, the lower end of the spring 16 is fixedly connected with the fixing base 11, the position of the belt 10 for stretching is limited by the insertion of the clamping piece 14 into the clamping groove 12, the clamping piece 14 is kept inserted into the clamping groove 12 in the elastic contraction state of the spring 16, the spring 16 is provided in two groups and is arranged at positions close to the front and rear end faces of the clamping piece 14, the two springs 16 are symmetrically arranged, the lower end of the clamping piece 14 is swung downward under the elastic contraction of the spring 16, the potential energy of the swinging of the clamping piece 14 is stable, and the limiting function of the clamping piece 14 is not completely lost due to the damage of the single spring 16; when it is needed to lengthen the distance between the cam block 9 and the belt 10, the pressing cover 15 can be pressed to release the position limitation of the belt 10 by the clamping piece 14, so that the extrusion strength of the pipe between the cam block 9 and the concave cam block 19 is conveniently adjusted.

[0029] The screw rod 17 is rotationally connected in the inner part of the bottom plate 6, one side of the screw rod 17 is fixedly connected with a roller 18, the outer surface of the screw rod 17 is threadedly connected with the inner surface of the sliding plate 7, the rolling directions of the two rollers 18 are set to be different, so that the extension distance of the sliding plate 7 is changed, the position distance between the cam block 9 and the concave cam block 19 is slightly adjusted, the pipe extrusion cross-sectional area is adjusted, and the limitation of the pipe flow rate is realized; the upper end of the pressing cover 15 is blocked by the side plate of the fixing base 11, the length of the pressing cover 15 is twice that of the side plate, the pressing cover 15 is arranged at the bottom of the side plate and has a close distance, and the long length of the pressing cover 15 ensures that the exposed part is convenient for the user to swing the clamping piece 14 by pressing to cancel the limiting function of the clamping piece 14 to the belt 10.

[0030] The working principle of the present application is as follows:

[0031] When the flow rate of the infusion pipe 1 is too high to cause discomfort to the patient, the belt 10 is stretched to one side of the fixed seat 11, which changes the position distance between the cam block 9 and the concave block 19. The bottom plate 6 is rotationally connected with a screw rod 17, one side of the screw rod 17 is fixedly connected with a roller 18, the outer surface of the screw rod 17 is threadedly connected with the inner surface of the slide plate 7. The slide plate 7 is adjusted in position when the roller 18 rotates in different directions, which changes the position distance between the cam block 9 and the concave block 19 again, so that the cross-sectional area of the catheter is reduced, thereby limiting the flow rate of the liquid in the pipeline, realizing the function of the regulator 3 having two adjustment modes to limit the flow of the pipeline, avoiding the discomfort of the patient caused by the high flow rate of the infusion pipeline, and partially replacing the function of the drop speed regulator.

[0032] The flow sensor 23 is electrically connected with the buzzer 4, and the middle part of the buzzer 4 is fixedly provided with the indicator light 21. After the PICC pipeline works for one day, the timer 25 transmits a signal to the indicator light 21 to emit a flickering light signal. When the time reaches one day, the timer 25 transmits a signal to the indicator light 21 to emit a flickering light signal, prompting to observe the skin around the puncture point every day.

[0033] When the PICC pipeline is expected to be indwelled for more than one week or the preset indwelling time, the flow sensor 23 is electrically connected with the timer 25, the flow sensor 23 is electrically connected with the buzzer 4, the buzzer 4 emits a sharp sound and the indicator light 21 emits a flickering light signal, prompting the pipeline to exceed the expected indwelling time and the medical staff to perform daily maintenance and record.
