Description

Guide function type negative pressure drainage tube

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a direction functional type negative pressure drainage tube.

Background

The clinical surgical drainage tubes have various types, some are used for catheterization, and some are used for wounds, thoracic cavities, brain cavities, gastrointestinal tracts, biliary tracts and the like. Surgical drainage is used for guiding pus, blood and liquid accumulated in human tissues or body cavities to the outside of a body so as to prevent postoperative infection and influence on wound healing. When the drainage tube is used for tube descending, the tube descending is particularly suitable for an enterogastric tube, and more times, whether the tube descending is correct or not is judged by experience (for example, whether the tube descending reaches the stomach is judged by pumping gastric juice, inflating, hearing and passing water sounds, the length of the tube descending and the like), so that the pain of a patient is caused, and the misjudgment is caused, so that the medical effect is greatly influenced. Keep the drainage tube pipeline unobstructed, pay attention to the observation at any time, do not receive pressurized and distortion, turn over the angulation to avoid influencing the drainage. The fixation of the drainage tube is also needed to avoid displacement and separation. When the drainage tube is used, the position of the drainage bottle is required to be higher than the plane of the mouth of the patient cannula. When the patient is moved, the drainage tube is clamped firstly; when the drainage liquid exceeds half of the bottle body, the bottle body is poured to prevent the counter-flow pollution caused by the high liquid level. Care was taken to keep the various drains clean from the wound or mucosal contact to prevent infection. And recording drainage color, properties and quantity, and reporting to doctors in time. When the medical staff observes that no drainage liquid flows out of the drainage tube, the medical staff usually judges that the accumulated liquid in the body cavity is completely removed or the drainage tube is abandoned due to the pressure, the twist or the corner. However, in some cases, the drainage of the drainage tube without effusion may also be caused by the fact that the drainage tube cannot contact with the effusion due to the position change of the drainage tube, and at this time, if it is determined that there is no effusion in the body cavity, the medical effect on the patient is seriously affected, even a medical accident is caused, and the drainage tube is discarded due to the situation, which causes great waste.

The LED lamp is more and more widely applied in the medical field, is a cold light lamp, can not generate heat when emitting light, and can set the wavelength. Research finds that low-power LED lamp irradiation can promote gastrointestinal mucosa recovery. High-energy ultraviolet light has been used for sterilization of medical instruments, and low-power ultraviolet light has no sterilization capability but has a bacteriostatic effect. Phototherapy is the treatment of human skin or certain tissue cells by using photobiological effect and illumination with specific wavelength to promote or inhibit growth. The efficacy of LED light sources for phototherapy is emerging.

The current drainage tube is mainly placed in a body cavity for positioning by means of CT, but the CT cost is higher, and the economic burden of a patient is increased; on the other hand, the drainage tube is easy to deform, is not easy to extend into organs such as esophagus, intestines and stomach, is easy to damage the esophagus and the mucous membranes of the intestines and stomach, and is easy to block due to the viscosity of drainage materials.
