[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0032] A specific embodiment of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, a blood purification loading kit is disclosed, including a medical packaging bag 10 and a first treatment towel 1, a second treatment towel 2, and a third treatment towel 3 disposed within the medical packaging bag 10. The second treatment towel 2 and the third treatment towel 3 are both connected to the first treatment towel 1. One edge of the second treatment towel 2 is connected to the upper part of the first treatment towel 1, and the third treatment towel 3 is connected to the junction of the first treatment towel 1 and the second treatment towel 2. The second treatment towel 2 can be folded towards the upper region of the first treatment towel 1 and can also be folded towards the third treatment towel 3.
[0033] For example, the second treatment towel 2 and the third treatment towel 3 are connected to the first treatment towel 1 by adhesive bonding, such as... Figure 1 , Figure 2 and Figure 3As shown, a gap 4 is provided at the junction of the second treatment towel 2, the third treatment towel 3, and the first treatment towel 1. This gap 4 is formed by a notch on the edge of the second treatment towel 2. It should be noted that the connection method of the first treatment towel 1, the second treatment towel 2, and the third treatment towel 3 is not limited to adhesive bonding; they can also be sewn together or connected using Velcro.
[0034] Furthermore, such as Figure 4 As shown, the first treatment towel 1 is divided into two areas, namely the first treatment area 11 and the second treatment area 12. The edge of the second treatment area 12 that is not connected to the first treatment area 11 is provided with an adhesive area 13, and the adhesive area 13 surrounds and forms a transparent observation area 14.
[0035] It is worth noting that, unlike the first treatment towel 1 which has two treatment zones, the second treatment towel 2 and the third treatment towel 3 each have only one treatment zone.
[0036] Preferably, the widths of the first treatment towel 1, the second treatment towel 2, and the third treatment towel 3 are equal, the length of the second treatment towel 2 is less than half the length of the first treatment towel 1, and the length of the third treatment towel 3 is equal to the length of the first treatment towel 1.
[0037] like Figure 3 As shown, the device also includes a syringe 5, a needle 6 (with a needle cap), a CVP kit 7, and a thrombosis observation box 8. CVP stands for Central Venous Pressure. The syringe 5, needle 6, CVP kit 7, and thrombosis observation box 8 are all mounted on the third treatment towel 3. Exemplarily, the syringe 5, needle 6, CVP kit 7, and thrombosis observation box 8 are adhered to the third treatment towel 3. Understandably, they can also be connected to the third treatment towel 3 in other ways; the adhesion method is only an example. The third treatment towel 3 is folded in half before use, covering the syringe 5, needle 6, CVP kit 7, and thrombosis observation box 8 when folded. It is unfolded before use. It should be noted that the number and type of needle 6 are compatible with the number and type of syringe 5.
[0038] Furthermore, such as Figure 3 As shown, a retainer 9 is provided on the third treatment towel 3 to hold the syringe 5. Exemplarily, the retainer 9 is adhered to the third treatment towel 3, and the syringe 5 is held in place by the retainer 9. Exemplarily, as... Figure 5 As shown, the card holder 9 has an arc-shaped groove on the base plate, and the syringe 5 is inserted into the arc-shaped groove.
[0039] CVP kit 7 is used to measure CVP, and thrombus observation kit 8 is used to observe thrombi. For example... Figure 6As shown, the upper layer of the thrombosis observation box 8 is a cross-woven fine gauze structure 81 (similar to the texture of fine gauze), and the lower layer is an absorbent layer 82 (similar to an absorbent sponge). The side of the thrombosis observation box 8 is equipped with a scale or a paper ruler, or a flexible measuring tape.
[0040] Preferably, the first treatment towel 1, the second treatment towel 2, and the third treatment towel 3 in this embodiment are in a folded state before use. For example, the first treatment area 11 of the first treatment towel 1 is folded approximately from the middle, the second treatment area 12 is also folded approximately from the middle, and the second treatment towel 2 is folded toward the folded third treatment towel 3.
[0041] Compared with the prior art, the blood purification machine-on-machine kit provided in this embodiment includes three treatment towels: a first treatment towel 1, a second treatment towel 2, and a third treatment towel 3. The second treatment towel 2 and the third treatment towel 3 are both connected to the first treatment towel 1. One edge of the second treatment towel 2 is connected to the upper part of the first treatment towel 1, and the third treatment towel 3 is connected at the junction of the first treatment towel 1 and the second treatment towel 2. The first treatment towel 1 includes a first treatment area 11 and a second treatment area 12. The second treatment area 12 has an adhesive area 13, which surrounds a transparent observation area 14. The third treatment towel 3 is equipped with a syringe 5, a needle 6, a CVP kit 7, and a thrombus observation box 8. By changing the treatment towels, a single-person aseptic machine-on-machine operation can be achieved, which is more convenient, saves machine-on-machine time, and reduces the risk of catheter infection due to inadequate sterilization.
[0042] Preferably, the syringe 5 is provided with six syringes: two 5ml syringes, two 10ml syringes, and two 20ml syringes, which can be selected as needed during operation.
[0043] like Figure 1 , Figure 3 As shown, the medical pack also includes sterile gauze 20, clean and sterile gloves 40, and a sterile kidney dish (not shown in the figure). The sterile gauze 20 and clean gloves 30 are positioned above the first treatment area 11, and the sterile gloves 40 are positioned above the third treatment towel 3. The sterile kidney dish is located on the top layer inside the medical packaging bag 10.
[0044] To secure the catheters on the dialysis machine, such as Figure 1 As shown, the first treatment area 11 is also equipped with Velcro 50.
[0045] The usage process of the computer-based learning package in this embodiment is as follows:
[0046] The nurse washes hands or uses hand sanitizer, wears a mask, protective clothing, and goggles, and affixes a medical waste bag (or places it on the top layer of the medical device bag) to the patient's bedside. Uncover the gauze on the patient's central venous catheter, ensuring the clamp is closed, but do not remove the gauze at this stage. Wash hands or use hand sanitizer, open the medical device bag, open the first treatment towel 1, and put on clean gloves 30. Use sterile gauze 20 from the medical device bag, soaked in external disinfectant, to wipe the catheter outside the dressing. Remove the gauze from the catheter (including the catheter tip cap and catheter clamp), wiping both arterial and venous ends for more than 15 seconds. Place the disinfected catheter on the first treatment towel 1. The nurse removes the clean gloves 30, places them in a yellow medical waste bag, disinfects hands with 3M hand sanitizer, removes the pre-filled tubing from the machine, and attaches the tubing to the first treatment towel 1 (specifically located in the first treatment area 11, using medical tape). Fold the second treatment towel 2 over the first treatment towel 1, so that the second treatment towel 2 covers the catheter, with the end of the catheter protruding through the slit 4. Unfold the third treatment towel 3, which contains a sterile kidney dish, two pieces of sterile gauze, two 20ml sterile syringes, two 5ml sterile syringes, two 10ml sterile syringes, a needle 6, a CVP kit 7, a thrombosis observation box 8, etc., arranged in an orderly and sterile manner. Open 10ml of 0.9% sodium chloride injection solution and place it on the treatment cart. Put on the sterile gloves 40 from the machine bag, pick up the 10ml sterile syringe and draw aspirate, keeping both hands sterile. Through the second treatment towel 2, use sterile gauze 20 to disinfect the cross-section and sides of the catheter connector, wiping vigorously from multiple directions for more than 15 seconds. Using a 5ml sterile syringe, draw 2ml of heparin locking solution from the arterial end of the catheter under negative pressure. Inject this solution into the thrombus observation box 8 to check for blood clots. If a clot is found, draw another 2ml and inject it into the thrombus observation box 8 for further examination. Measure the length of the thrombus using a soft ruler or the scale on the side of the thrombus observation box 8. (If blood clots are found after three consecutive tests, discontinue use of the catheter and notify the attending physician). Slowly and evenly draw blood from the catheter using a 20ml syringe (filling the syringe in 6 seconds) to check for patency. Pulsatiate the catheter with 10ml of 0.9% sodium chloride injection without removing the syringe. The procedure for the venous end of the catheter is the same as for the arterial end. Connect the arterial end of the dialysis tubing to the arterial end of the central venous catheter, ensuring sterility. Connect the venous end of the dialysis tubing to the venous end of the central venous catheter, vent air, and maintain sterility. Check that all branches of the dialysis tubing are clamped and the safety caps are tightened, following the blood flow direction. Ensure the central venous catheter and dialysis tubing are securely connected. Remove the second treatment towel (2) and the third treatment towel (3). Add the anticoagulant as prescribed, verifying the patient's anticoagulant dosage. Turn on the blood pump, draw blood at a low rate, vent air from the membrane again, slowly increase the blood flow rate, and set the treatment parameters.After the machine enters treatment mode, double-check that the tubing connections are secure, the treatment parameters are correct, and the dialysate concentration and dosage are accurate. At this point, place the dialyzer with the arterial end facing upwards. After verifying that everything is correct, fold the second treatment zone 12 and attach it to the first treatment zone 11. If necessary, secure it with medical tape. Observation zone 14 can be used to observe catheter connections and bleeding. Wipe the dialysis machine with sterile wipes, clean the equipment used for the machine, sort the waste, and remove sterile gloves to wash hands. If necessary, inform the patient or their family and the responsible nurse in the ward about precautions during dialysis treatment after starting the machine.
