Abstract
Description
Technical Field
[0001] This utility model relates to the field of clinical nursing technology, and more specifically, to a catheter infection flushing device. Background Technology
[0002] Catheter placement is an invasive clinical procedure, usually performed to achieve a certain therapeutic effect or as a necessary procedure in the medical process. For example, patients with pleural effusion, ascites, or pneumothorax may require pleural or abdominal catheters to help drain air and fluid, thus continuously draining the effusion or air; or a stoma may be placed to provide the patient with a feeding tube.
[0003] To care for the catheter insertion wound and reduce the risk of infection, a flushing device is usually installed on the outside of the catheter.
[0004] Based on the above, the inventors discovered that existing irrigation devices require the assembly of an ostomy bag, connecting tube, transparent dressing, and suction tube, which is cumbersome to manufacture, time-consuming, inconvenient for medical staff to operate, and has poor sealing performance. Therefore, in view of this, the inventors have studied and improved the existing structure to provide an irrigation device for intubation infection, in order to achieve a more practical purpose.

[0041] Existing irrigation devices require the assembly of ostomy bags, connecting tubes, transparent dressings, and suction tubes, which are cumbersome, time-consuming, and inconvenient for medical staff to operate. They also have poor sealing performance. Therefore, this study aims to improve the existing structure and provide an irrigation device for catheter-related infections, with the goal of achieving greater practical value.
[0042] The inventors secured the ostomy bag with a sealing gasket, then inserted multiple tubes sequentially into the bag. The fixing opening was then secured with a fixing strap to maintain the tube position and ensure the ostomy bag's airtightness. Finally, the oxygen tube, negative pressure tube, and irrigation tube worked together to perform negative pressure irrigation on the wound. Compared to existing technologies, this modular, sealed negative pressure irrigation assembly is simple in structure, easy to operate, and provides excellent sealing, improving irrigation effectiveness, reducing operation time, increasing work efficiency, alleviating patient discomfort, reducing complications, and contributing to a higher wound infection healing rate.
[0043] This embodiment relates to a catheter infection flushing device, which can be applied in various application scenarios of catheter placement in clinical nursing.
[0044] Example:
[0045] Please see Figure 1-6 An intubation infection flushing device includes an ostomy bag 1, a fixing port 2 is provided at the rear end of the ostomy bag 1, a fixing strap 3 is fixedly connected to the outside of the fixing port 2, and a nutrition tube 4 is provided through the inside of the fixing port 2. An oxygen tube 5, a negative pressure tube 6 and a flushing tube 7 are arranged in sequence on the outside of the nutrition tube 4.
[0046] The nutrition tube 4, the oxygen tube 5, the negative pressure tube 6, and the flushing tube 7 are separate tubes. The flushing tube 7 is used to clean the wound, mainly using physiological saline. After flushing, it is drawn out from the negative pressure tube 6. The flushing tube 7 is used to flush infected wounds.
[0047] Nutritional tube 4 refers to a feeding tube, while a stoma tube is used for patients with advanced esophageal cancer. Typically, doctors don't remove the esophagus; instead, a tube is left in the abdomen. This is a treatment method for patients with advanced esophageal cancer to alleviate their difficulties in eating and drinking, and also to achieve a therapeutic effect.
[0048] Oxygen tube 5 provides oxygen to ostomy bag 1, negative pressure tube 6 provides negative pressure to ostomy bag 1, oxygen switch is installed on oxygen tube 5, negative pressure switch 61 is installed on negative pressure tube 6, and flushing switch is installed on flushing tube 7.
[0049] The front end of the ostomy bag 1 is fixedly connected to the bottom of the sealing gasket 8, and the top surface of the ostomy bag 1 is fixedly connected to the observation film 9. The sealing gasket 8 has a through hole 10 in the middle, and the bottom surface of the sealing gasket 8 is fixedly connected to the bottom paper 11. Tear off the bottom paper 11 and attach the sealing gasket 8 to the surface of the patient's wound so that the through hole 10 is aligned with the wound position.
[0050] The nutrition tube 4 is disposed through the through hole 10, the flushing tube 7 is disposed facing the through hole 10, and the bottom of the sealing gasket 8 is adhesive. After tearing off the bottom paper 11, the sealing gasket 8 is attached close to the patient's wound.
[0051] See Figure 1 The inner ends of oxygen tube 5, negative pressure tube 6, and flushing tube 7 are all located inside the ostomy bag 1. The outer end of oxygen tube 5 is connected to an external oxygen source, the outer end of negative pressure tube 6 is connected to a negative pressure source, and the outer end of flushing tube 7 is connected to a saline bag.
[0052] See Figure 1 The inner surface of the fixing port 2 is attached to the outer surface of the nutrition tube 4, oxygen tube 5, negative pressure tube 6 and flushing tube 7. The fixing port 2 is tied and pasted with the fixing strap 3 to fix the position of the tubes and ensure the airtightness of the ostomy bag 1.
[0053] See Figure 2 The observation membrane 9 is transparent. The inner end of the nutrition tube 4 passes through the through hole 10. The through hole 10 is cut according to the size of the patient's wound. First, the nutrition tube 4 is inserted into the ostomy bag 1, so that the inner end passes through the through hole 10 and enters the patient's body. Then, the oxygen tube 5, the negative pressure tube 6, and the flushing tube 7 are inserted into the ostomy bag 1 in sequence.
[0054] See Figure 3 The fixing strap 3 is attached end to end.
[0055] See Figure 4 The nutrition pipe 4, oxygen pipe 5, negative pressure pipe 6, and flushing pipe 7 are all transparent.
[0056] See Figure 5Both the sealing gasket 8 and the through hole 10 are arranged in a ring shape.
[0057] See Figure 1 The ostomy bag 1 is made of a sealing and waterproof material.
[0058] In use: First, cut the through hole 10 according to the size of the patient's wound, then tear off the bottom paper 11, and attach the sealing gasket 8 to the surface of the patient's wound, aligning the through hole 10 with the wound position. Then, insert the nutrition tube 4 into the ostomy bag 1, with one end passing through the through hole 10 into the patient's body. Next, insert the oxygen tube 5, negative pressure tube 6, and irrigation tube 7 into the ostomy bag 1 in sequence. Then, use the fixing strap 3 to tie and stick the fixing port 2 to fix the position of the tubes and ensure the airtightness of the ostomy bag 1. Then, turn on the oxygen switch and adjust the oxygen flow rate to 7L / min, maintaining it for 15-20 minutes, twice a day. After that, turn off the oxygen switch and turn on the irrigation switch and negative pressure switch at the same time. Use the negative pressure tube 6 in conjunction with the irrigation tube 7 to perform negative pressure irrigation on the wound to reduce the risk of wound infection.
[0059] In this embodiment, the ostomy bag is fixed by a sealing gasket, and then multiple tubes are inserted into the ostomy bag in sequence. The fixing opening is then tied and glued with fixing straps to fix the tube positions and ensure the ostomy bag's airtightness. Finally, the oxygen tube, negative pressure tube, and irrigation tube work together to perform negative pressure irrigation on the wound. Compared with the prior art, the combined sealed negative pressure irrigation component has a simple structure, is easy to operate, and has good sealing performance. It can improve the irrigation effect, reduce operation time, improve work efficiency, reduce patient discomfort and complications, and help improve the wound infection healing rate.
