Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a PICC pipeline maintenance tracking and reminder device. Background Art
[0002] The PICC line is a central venous catheter that is inserted through a peripheral vein puncture and places the tip of the catheter in the superior vena cava or superior vena cava. It provides patients with a long-term and safe intravenous infusion route and can be used to infuse various drugs, nutrients, and blood products. The PICC tube can be left in place for six months to one year. During the period when the patient is not receiving infusion, the film is routinely replaced and the tube is flushed and sealed once every seven days. During daily care, medical staff need to observe whether the skin around the puncture point is red, swollen, or exuded. The use of PICC can prevent patients from facing damage to blood vessels caused by irritating drugs due to long-term infusion, and reduce the pain caused to patients by repeated punctures.
[0003] The most common way to adjust the drip rate of the PICC pipeline is with a manual drip rate regulator, but this method is one of the parts that is most prone to problems in pipeline adjustment. If the pipeline flow rate is too high, it will irritate and damage the blood vessels, causing the patient to feel pain, swelling, fever and other symptoms. Therefore, it is necessary to set a secondary flow limit for the pipeline flow and detect the pipeline flow conditions. This has positive significance for pipeline maintenance and can remind medical staff to pay attention to the pipeline retention time and observe the condition of the pipeline and surrounding skin. Summary of the invention
[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a PICC pipeline maintenance tracking and reminder device, which can effectively solve the problems of poor flow rate adjustment effect of the manual drip rate regulator in the prior art and lack of timed reminders for PICC pipeline inspection and penetration of the skin around the needle hole puncture part.

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The present invention detects that the flow rate in the pipeline is too fast through the flow sensor, and the flow sensor display screen displays a value or the wireless data module sends a signal to the computer as a terminal. The computer prompts that the tracked flow rate is too high, and the cam block is squeezed toward the cam block position and deformed to change the cross-sectional area of the PICC pipeline, thereby slowing down the flow rate of the liquid in the pipeline; the position distance between the cam block and the cam block is changed by setting the belt during the stretching process toward one side of the fixed seat, and the position distance between the cam block and the cam block is changed again under the adjustment of the roller; the regulator has two adjustment modes to choose from to limit the flow of the pipeline, thereby avoiding discomfort to the patient due to the excessively high flow rate of the infusion pipeline.
[0014] 2. The present invention detects that the PICC tube is in a working state of conveying liquid by setting a flow sensor. The electrical signal detected by the flow sensor is transmitted to a timer. The timer calculates that it is time to observe the skin condition around the puncture point every day according to the timing time. When one day is reached, the timer transmits a signal to the indicator light to emit a flashing light signal; when the PICC tube is expected to be retained for more than one week or the preset retention time, the buzzer emits a sharp sound and the indicator light emits a flashing light signal; in a variety of prompting methods, the medical staff is informed whether to replace the catheter or observe the patient's puncture point and other parts to record maintenance information.

[0019] The present invention will be further described below in conjunction with the embodiments. Example
[0020] Reference Figures 1 to 6A PICC pipeline maintenance tracking and reminder device includes an infusion tube 1 and a silicone patch 2. A regulator 3 is fixedly arranged on the upper part of the silicone patch 2. The silicone patch 2 is used as a double-sided adhesive film installation position to be attached to a position close to the catheter such as the internal jugular vein or the femoral vein. A buzzer 4 is also fixedly arranged on the upper part of the silicone patch 2. An indicator light 21 is fixedly arranged in the middle of the buzzer 4. A timer 25 is fixedly arranged on the upper part of a flow sensor 23. The flow sensor 23 is electrically connected to the timer 25. The flow sensor 23 is electrically connected to the buzzer 4. By or setting The buzzer 4 and the indicator light 21 receive the signal transmitted by the flow sensor 23 to determine whether the indicator light 21 is turned on and flashes, which reminds you to observe the skin condition around the puncture point every day. After the buzzer 4 and the indicator light 21 are turned on, the buzzer 4 sounds and the flashing light signal is emitted, which reminds the medical staff that the pipeline exceeds the expected retention time and needs daily maintenance and record-keeping; a flow sensor 23 is fixedly installed on one side of the infusion tube 1, and threaded bolts 24 are fixedly arranged on both sides of the flow sensor 23. A collar 22 is fixedly arranged on the side wall of the buzzer 4, and the inner surface of the collar 22 is connected to the infusion tube 1. The outer surface of the PICC is fixedly installed, and the collar 22 is used to install the pipeline. It can be installed on the PICC pipeline in a through-going manner, or the two ports of the pipeline can be installed separately; the flow sensor 23 can not only detect the flow rate of the delivered liquid, but also provide a judgment on whether the pipeline is working. The flow sensor 23 belongs to a medical flow sensor, which is a device for accurately measuring and monitoring the flow of liquid or gas in a medical pipeline. Its main function is to ensure that the delivery amount of liquid or gas during the medical process is accurate, which is crucial to the safety and effect of the patient's treatment; the regulator 3 includes a bottom plate 6, a bottom plate The upper surface of the plate 6 is slidably connected with a slide plate 7, one side of the slide plate 7 is hinged with a cam block 9, the side wall of the bent plate 8 is fixedly provided with a cam block 9, the outer wall of the middle position of the bottom plate 6 is fixedly connected with a fixing seat 11, the outer wall of the fixing seat 11 is fixedly connected with a cam block 19, the upper end of the bent plate 8 is hinged with a belt 10, the top of the fixing seat 11 is movably installed with the belt 10, the belt 10 is provided with a card slot 12, and the cam block 9 is moved closer to the position of the cam block 19, so that the cross-sectional area of the conduit becomes smaller, thereby limiting the circulation speed of the medicine solution in the pipeline, and realizing the function of partially replacing the drip rate regulator.
[0021] The inner surface of the upper part of the fixed seat 11 is rotatably connected with a rotating shaft 13, and a card 14 is fixedly arranged on one side of the rotating shaft 13. The card 14 is inserted into the inner surface of the card slot 12. The size of the opening of the card slot 12 is larger than the card 14, and the gap between the card slot 12 and the card 14 is about 0.3 mm; by setting the length and width of the card slot 12 to be larger, a position gap is provided for the insertion of the card 14. In this way, it is ensured that the card 14 can smoothly pass through the card slots 12 at different positions on the belt 10 to avoid excessive shaking of the belt 10 during the stretching process due to excessive gaps; a pressure cover 15 is fixedly arranged on the other side of the rotating shaft 13, and a spring 16 is fixedly connected to the lower end of the card 14. The lower end of the spring 16 is fixedly connected to the fixed seat 11. By setting the card 14 to be inserted into the card slot 12, the position of the belt 10 stretching can be limited, and the spring 16 is in an elastic contraction state to keep the card 14 Inserted into the card slot 12, two groups of springs 16 are provided, and the springs 16 are respectively arranged at positions close to the front and rear end surfaces of the card 14. Through the symmetrical arrangement of the two springs 16, the springs 16 pull the lower end of the card 14 to swing downward in an elastically contracted state, thereby ensuring that the potential energy of the card 14 swinging downward is stable, and the limiting function of the card 14 will not be completely invalidated due to damage to a single spring 16; when it is necessary to extend the distance between the cam block 9 and the belt 10, the pressure cover 15 can be pressed to release the position limit of the card 14 on the belt 10, so as to facilitate the adjustment of the extrusion strength of the cam block 9 and the concave wheel block 19 on the pipeline.
[0022] The bottom plate 6 is internally rotatably 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 to the inner surface of the slide plate 7, and the extension and retraction distance of the slide plate 7 is changed by setting the roller 18 to rotate in two different directions, so as to achieve a slight adjustment of the position distance between the cam block 9 and the concave wheel block 19 to adjust the pipeline extrusion cross-sectional area, thereby completing the restriction on the pipeline flow rate; the upper end of the pressure cover 15 is blocked by the side plate of the fixed seat 11, and the length of the pressure cover 15 is twice that of the side plate. The pressure cover 15 is located at the bottom of the side plate and has a closer distance. The long length of the pressure cover 15 ensures that there is an exposed part, which is convenient for the user to use a pressing method to drive the card 14 to swing to cancel the card 14 limiting function on the belt 10.
[0023] The working principle of the present invention is as follows: When it is detected that the flow rate of the infusion tube 1 is too high and causes discomfort to the patient, the belt 10 is set to change the position distance between the cam block 9 and the cam block 19 during the stretching process to one side of the fixed seat 11, the bottom plate 6 is internally rotatably connected with a screw 17, one side of the screw 17 is fixedly connected with a roller 18, the outer surface of the screw 17 is threadedly connected to the inner surface of the slide plate 7, and the position of the slide plate 7 is adjusted when the slide plate 7 rotates in different directions of the roller 18, and the position distance between the cam block 9 and the cam block 19 is changed again, so that the cross-sectional area of the conduit becomes smaller, thereby limiting the circulation speed of the medicine in the pipeline, and realizing that the regulator 3 has two adjustment modes to choose from to limit the flow of the pipeline, avoiding the discomfort caused to the patient due to the excessively high flow rate of the infusion pipeline, and partially replacing the function of the drip rate regulator; The flow sensor 23 is electrically connected to the buzzer 4, and an indicator light 21 is fixedly arranged in the middle of the buzzer 4. After the PICC pipeline has been working for one day, the timer 25 transmits a signal to the indicator light 21 to emit a flashing light signal. When the time of one day is reached, the timer 25 transmits a signal to the indicator light 21 to emit a flashing light signal, which reminds you to observe the skin condition around the puncture point every day. When the expected retention time of the PICC line exceeds one week or the preset retention time, the flow sensor 23 is electrically connected to the timer 25, and the flow sensor 23 is electrically connected to the buzzer 4, the buzzer 4 emits a sharp sound and the indicator light 21 emits a flashing light signal, prompting the medical staff to perform daily maintenance and record the line beyond the expected retention time.
