Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to an anti-pollution protection device for a deep vein catheter infusion connector end. Background Art
[0002] Patients often need to have single-lumen or multi-lumen deep venous catheters placed in the veins for infusion, vasoactive drugs, chemotherapy drugs and other irritating drugs. These include central venous catheters (CVCs) placed through the internal jugular vein or femoral vein, as well as peripherally inserted central venous catheters (PICCs) or peripherally inserted mid-length catheters (PQCs) placed through the median cubital and basilic veins. These catheters are usually placed in the veins longer than general indwelling needles, often ranging from 1 week to several months. In addition, the indwelling catheter connectors require frequent operation and exposure due to the wide variety of drug use, which may cause connector contamination and even lead to catheter-related infection and bloodstream infection. Once catheter-related infection is considered, removal and replacement are often chosen, which is costly and reduces the number of puncture sites, all of which have adverse effects on patients. In addition, in clinical practice, the catheter connector is often located in the head and neck (internal jugular vein / subclavian vein catheterization) or perineum (femoral vein catheterization). The head and neck are often splashed with body fluids such as oral secretions from patients, and the perineum is contaminated with urine and feces. In addition, this area is an area where patients have a large range of motion, and infection often occurs due to displacement caused by patients turning their heads, actively or passively turning over, moving their legs, changing beds, etc. In current clinical practice, treatment towels are often used for wrapping. As patients move and undergo treatment operations, treatment towels may fall off, be lifted up, or shift in various situations, causing many inconveniences and extra workloads for nursing and treatment. In addition, in many cases, disposable treatment towels are chosen, which are light and easily blown away by the wind. Reusable treatment towels used in operating rooms are too heavy and easily compress the pipeline, resulting in poor follow-up, and may be pulled and cause the pipeline to fall off when turning over or moving.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0023] like Figure 1As shown, a deep vein catheter infusion connector end anti-contamination protection device includes a connector end protection device 1 for protecting an unused lumen in a deep vein catheter and a serial connector protection device 2 for protecting a used lumen in a deep vein catheter. Both the connector end protection device 1 and the serial connector protection device 2 are made of a cloth material with a hydrophobic outer layer and a water-absorbent inner layer.
[0024] like Figure 2 As shown, the joint end protection device 1 includes a first back surface 11 with a first adhesive surface on the inner layer and a first front surface 12 with a second adhesive surface on the inner layer, the first back surface 11 includes a first body 13, one end of the first body 13 is provided with a first neck 14, the shape and size of the first front surface 12 are the same as the shape and size of the first back surface 11, and a first transparent window 15 corresponding to the first neck 14 is provided on the first body 13 of the first front surface 12, and the first back surface 11 and the first front surface 12 are detachably bonded together by the first adhesive surface and the second adhesive surface. Figure 3 As shown;
[0025] like Figure 4 As shown, the series joint protection device 2 includes a second back surface 21 with a third adhesive surface in the inner layer and a second front surface 22 with a fourth adhesive surface in the inner layer, the second back surface 21 includes a second body 23, and the second neck 24 and the third neck 25 are respectively arranged at the opposite ends of the second body 23, the shape and size of the second front surface 22 are the same as those of the second back surface 21, and the second transparent window 26 corresponding to the second neck 24 and the third neck 25 is arranged on the second body 23 of the second front surface 22, and the second back surface 21 and the second front surface 22 are detachably bonded together by the third adhesive surface and the fourth adhesive surface. Figure 5 shown.
[0026] In some embodiments, the first adhesive surface is the hook surface of Velcro, and the second adhesive surface is the fleece surface of Velcro; in other embodiments, the first adhesive surface is the fleece surface of Velcro, and the second adhesive surface is the hook surface of Velcro.
[0027] In some embodiments, the third adhesive surface is the hook surface of Velcro, and the fourth adhesive surface is the fur surface of Velcro; in other embodiments, the third adhesive surface is the fur surface of Velcro, and the fourth adhesive surface is the hook surface of Velcro.
[0028] In some embodiments, Figure 6As shown, the unused lumen 3 in the deep venous catheter passes through the first neck 14 and is located between the first back side 11 and the first front side 12 , and the end of the unused lumen 3 is blocked by the heparin cap 4 and is located within the range of the first transparent window 15 .
[0029] In some embodiments, Figure 7 As shown, the used lumen 5 in the deep venous catheter passes through the second neck 24 and the third neck 25 and is located between the second back side 21 and the second front side 22, and the three-way interface 6 of the used lumen 5 is located within the range of the second transparent window 26 and is led out from between the second back side 21 and the second front side 22 through the infusion line 7.
[0030] In some embodiments, the second neck 24 is wider than the third neck 25. Since the used lumen 5 passing through the second neck 24 is used to connect the infusion end, and the used lumen 5 passing through the third neck 25 is used to connect the deep vein catheter lumen at the patient end, and the infusion tube is usually thicker than the deep vein catheter lumen, the second neck 24 is wider than the third neck 25.
[0031] In some embodiments, on the second front side 22, the second transparent window 26 is located at the middle upper side or the middle lower side of the second body 23. Since the three-way interface 6 of the used lumen 5 is located within the range of the second transparent window 26 and is led out from between the second back side 21 and the second front side 22 through the infusion line 7, in order to ensure the stability of the fixation of the infusion line 7, the infusion line 7 can pass through a wider fixing surface, and the second transparent window 26 is set at the middle upper side or the middle lower side of the second body 23, so that a wider fixing surface can be reserved on one side to fix the infusion line 7.
[0032] When the device of the utility model is used to protect the end of the deep vein lumen connector, the deep vein catheters usually placed clinically are double-lumen or triple-lumen, such as Figure 6 As shown in the figure, when the deep vein catheter lumen is not used for infusion, the unused lumen 3 tail end is sealed with a heparin cap 4, and this structure is placed in the connector end protection device 1. Figure 7 The figure shows that when the lumen 5 is used for infusion, the three-way interface 6 is connected to different drug infusion lines 7, and the part is placed in the series joint protection device 2.
[0033] In patients with indwelling central venous catheters, the daily use frequency of the catheter is high, and the daily maintenance workload is large. The common catheterization sites of critically ill patients are at high risk of body fluid contamination, and the patient's resistance is poor. If a catheter-related infection occurs, it will bring adverse consequences to the patient. Therefore, good maintenance of the catheter connector is a crucial part of reducing catheter-related infections. Compared with the traditional commonly used treatment towel cover, this set of devices can be repeatedly disinfected and used, reducing the consumption of disposable treatment towels. The anti-fouling and waterproof characteristics of the outer structure can reduce the splashing of patient body fluids on the connector, reduce the chance of contamination, form a relatively closed and isolated space, reduce the probability of contamination, and reduce the economic and labor costs caused by connector replacement. The vecro Velcro structure of the inner layer of this device can help better fix the pipeline, reduce the risk of the isolation towel being lifted when the patient is active, moving and turning over, and reduce the failure of the mask due to external factors. This protective device is light in weight and can move with the connector, reducing the risk of tube removal caused by dragging the pipeline. The isolation towel has a visual window that can view the internal situation in real time, which is convenient for judgment and adjustment.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
