Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a flushing bag for a PICC or a port needle for preventing tube blockage. Background Art
[0002] PICC, or peripherally inserted central catheter, is an auxiliary infusion method that uses a catheter to puncture the vein in the arm. The other end of the catheter directly reaches the large vein near the heart, avoiding direct contact between the arm vein and chemotherapy drugs. At the same time, the blood flow rate of the large vein is fast, which can quickly dilute the chemotherapy drugs and reduce the risk of phlebitis. In addition, peripheral blood vessels have large selectivity, less trauma, and low infection rate, which can reduce patient pain and are suitable for situations that require long-term treatment. In the 1970s, PICC technology began to be applied in practice, and the United States took the lead in applying PICC technology to pediatric malignant tumor patients. With the continuous development of technology, ultrasound-guided PICC puncture and catheterization was first completed by a nurse named Claudette Boudreaus at the Washington Medical Center in 1997. In the same year, PICC technology was introduced to China. In the development of PICC technology, preventing tube blockage has always been an important concern. With the advancement of materials science and the improvement of medical technology, the materials and puncture techniques of PICC catheters are constantly being updated. Today, PICC catheters come in a variety of brands and models, and puncture technology has evolved from the earliest blind puncture to the widespread use of PICC puncture under ultrasound guidance. This technology verifies the tip position of the catheter through bedside filming to ensure that it is used after the preset position, greatly reducing the risk of tube blockage. As for the port needle, it is also a medical device used for long-term infusion or chemotherapy. Similar to PICC, preventing port needle blockage is also an issue that needs to be paid attention to in medical practice. With the advancement of medical technology, the design and use of port needles are also being optimized to reduce the risk of tube blockage.
[0003] Traditional PICC or port needles may become blocked due to various reasons, such as: twisted and folded catheters; various precipitations caused by drug interactions; and the patient's blood status, body position and activity. There will be resistance during drug administration, difficulty in dripping, increased resistance or inability to push intravenous injections, and no blood return during withdrawal. Secondly, blockage may cause interruption of treatment, affecting the patient's treatment effect and recovery process. Furthermore, blockage may increase the patient's pain and discomfort. At this time, most home patients need to rush to the hospital for the doctor to clear the catheter. If the blockage occurs at night and the patient is alone at home, it will be very inconvenient.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-5 , a flushing bag for a PICC or port needle with an anti-blocking tube, comprises an inner shell 1 and an outer shell 9, the outer shell 9 is buckled on the inner shell 1, and the outer shell 9 is connected to the inner shell 1 by an adhesive tape 91, and the inner shell 1 and the outer shell 9 together constitute a closed space for storing and protecting the internal items, such as disposable gloves 7, alcohol cotton pads 5, No. 1 syringe 2 and No. 2 syringe 3, etc. Ensure that the items will not be contaminated or damaged during carrying and use, and at the same time, it is convenient for users to take them at any time. The adhesive tape 91 is used to firmly buckle the outer shell 9 on the inner shell 1, ensure the stability and sealing of the entire structure, prevent the items from accidentally falling or the outer shell 9 from accidentally opening, and ensure safe use. The inner shell 1 is square in shape, and a limiting plate 2 12 is arranged in the middle of the inner shell 1. There are two limiting plates 12, and there is a gap between the two plates. A limiting plate 11 is arranged on the side inside the inner shell 1, and ears of the No. 1 syringe 2 and the No. 2 syringe 3 are respectively clamped in the limiting plate 2 12. Pistons 4 are assembled inside the No. 1 syringe 2 and the No. 2 syringe 3, and the pistons 4 are clamped on the limiting plate 11. The two ears of syringe No. 1 and syringe No. 2 are respectively snapped in the gap of the limiting plate 12, so that the position of syringe No. 1 and syringe No. 2 can be fixed. On the one hand, it can prevent syringe No. 1 and syringe No. 2 from moving freely inside the inner shell 1, causing the internal parts to be messy. Secondly, since syringe No. 1 and syringe No. 2 are filled with liquid medicine, the rear of syringe No. 1 and syringe No. 2 needs to be sealed by piston 4, and piston 4 is also snapped on the limiting plate 11, which can ensure that piston 4 will not be mistakenly pushed into syringe No. 1 and syringe No. 2, resulting in the loss of liquid medicine. The injection port 21 of syringe No. 1 and syringe No. 2 is equipped with a rubber stopper 7. Since liquid medicine is placed in the No. 1 syringe 2 and the No. 2 syringe 3, and there are certain requirements for the storage and sealing of the liquid medicine, the injection port 21 at the front end of the No. 1 syringe 2 and the No. 2 syringe 3 is sealed by a rubber stopper 7, and a stable sealed storage space is formed in the middle of the syringe together with the piston 4 at the rear of the No. 1 syringe 2 and the No. 2 syringe 3 to ensure the long-term effectiveness of the liquid medicine.
[0024] In addition, the limiting plate 2 12 and the limiting plate 1 11 play a supporting role for the middle part of the entire outer shell 9, and can form a certain pressure resistance when the outer shell 9 is impacted by a large external pressure, thereby protecting the internal items. Disposable gloves 6 are placed between the No. 1 syringe 2 and the No. 2 syringe 3, and the disposable gloves 6 protect the user's hands and prevent contamination or injury during operation. Improve the hygiene and safety of the operation. At least two alcohol cotton pads 5 are placed between the two pistons 4, and the alcohol cotton pads 5 are used to disinfect the catheter connector or heparin cap, kill potential bacteria, and prevent infection. Ensure the sterility of the operation and reduce the risk of infection. A sponge 13 is placed at the bottom of the remaining space of the inner shell 1, and the position where the sponge 13 is placed for the corresponding items is provided with a depression. The sponge 13 is used to fix and separate the No. 1 syringe 2, the No. 2 syringe 3 and other items, and the depression ensures that these items can be stably placed in the designated position. Prevent the items from moving or colliding during the carrying process to ensure the integrity and safety of the items. The No. 1 syringe 2 contains 10 ml of normal saline, and the No. 2 syringe 3 contains 5 ml / 50 Iu of sodium heparin tube-sealing injection. Normal saline is used to flush the catheter to remove residual drugs and blood; sodium heparin tube-sealing injection is used to seal the catheter to prevent catheter blockage. Maintain the functionality and patency of the catheter and reduce the risk of tube blockage. It is convenient for users to perform flushing and tube-sealing operations to maintain the patency and functionality of the catheter.
[0025] A taking groove 14 is provided on the side of the inner housing 1 corresponding to the injection port 21 and the end of the piston 4. Since the No. 1 syringe 2, the No. 2 syringe 3 and the piston 4 are all clamped in the limiting plate 11 and the limiting plate 2 12, it is difficult to take them out. Therefore, a taking groove 14 is provided on the side of the inner housing 1 corresponding to the injection port 21 and the end of the piston 4. When taking them out, both hands are inserted into the taking groove 14, and the No. 1 syringe 2, the No. 2 syringe 3 and the piston 4 can be easily taken out together.
[0026] The material of the inner shell 1 and the outer shell 9 is plastic. Plastic has certain strength and long service life, and can better preserve the internal items.
[0027] The upper part of the inner shell 1 is sealed by a sealing tin foil film 8. The sealing tin foil film 8 seals the upper part of the inner shell 1 to prevent dust or moisture from entering the interior, thereby keeping the internal items clean and dry and extending their service life.
[0028] The capacity of No. 1 syringe 2 and No. 2 syringe 3 is 10ml. One flushing will use about 10ml of normal saline and 5ml / 50Iu of sodium heparin tube sealing injection. In order to minimize the volume of the entire flushing package, it is most economical to use No. 1 syringe 2 and No. 2 syringe 3 with a capacity of 10ml.
[0029] There are at least two pairs of disposable gloves 7. Multiple pairs of disposable gloves 7 can prevent the patient from damaging the gloves due to improper operation during operation, so that new disposable gloves 7 can be replaced.
[0030] Working principle: When the patient is alone at home and it is inconvenient to go to the hospital late at night, and the PICC or port needle is blocked again. The patient can take out the flushing bag, first tear off the tape 91, remove the outer shell 9, and then tear off the sealing tin foil film 8 on the upper part of the inner shell 1. First, take out the disposable gloves 6 and put them on your hands, and use the alcohol cotton pad 5 to rub and disinfect the heparin cap of the PICC or infusion tube for no less than 15 seconds. Then, take the No. 1 syringe 2 and the No. 2 syringe 3 out of the inner shell 1 through the taking slot 14. Observe whether there is blood return. If there is blood return, flush it immediately to prevent blockage. Use the pulse flushing method, that is, push-stop-push-stop, 0.5-1 ml each time, so that the liquid forms a vortex in the catheter, which is conducive to flushing the residual drugs in various aspects of the catheter. After flushing the catheter, use the sodium heparin tube sealing injection in the No. 2 syringe 3 to seal the tube. The positive pressure tube sealing method is used, that is, when there is 0.5-1ml of sodium heparin tube sealing solution left, the syringe is pushed and withdrawn, and the injection speed should be greater than the withdrawal speed to ensure that the catheter is filled with tube sealing solution to prevent blood reflux. With such a set of blood return flushing kit, flushing operations can be performed even when the patient is alone or it is inconvenient to go to the hospital.
[0031] Operation steps: 1. Open the flushing bag and put on disposable gloves 6;
[0032] 2. Then use alcohol pad 5 to disinfect the heparin cap of PICC or infusion tube;
[0033] 3. Use 5-10 ml of saline in a No. 1 syringe to flush the tube;
[0034] 4. Seal the tube with 5 ml of sodium heparin sealing solution in No. 2 syringe 3.
