Embodiment 1

[0035] Such as figure 1 Shown, a kind of single-yarn medical multifunctional nasal plug, only by a superabsorbent fiber yarn (TechnicalAbsorbents Ltd, No.2085206) knitting one-time forming through short stitch. The medical multifunctional nasal plug is a hollow ellipsoid.

[0036] The medical multifunctional nasal plug has a high porosity, and the connectivity of the pores reaches 100%, so it has good air permeability. Good elasticity can make it fit well with the shape of human nasal threshold. Good support ensures that it can be stably fixed in the nasal threshold. Excellent water absorption and water retention properties. It is easy to load drugs and can realize local controllable sustained release of drugs. The structure is simple, the molding process is controllable, and it is easy to realize automation and standardization.

[0037] The present invention also provides the preparation method of above-mentioned medical multifunctional nasal plug, and concrete steps are...

Abstract

The invention discloses a single thread medical multifunctional nasal insert and a preparation method thereof. The single thread medical multifunctional nasal insert is characterized in that the nasal insert is formed by a yarn through knitting at a one-time molding. The porosity is high, and the aperture connectivity can be up to 100%, therefore, a good permeability is provided. A good elasticity can help the nasal insert fit with the nose threshold form of a human body well. A good support guarantees that the nasal insert can be stably fixed inside the nose threshold. Both water absorbing and water retention performance are excellent. Medicine can be loaded easily, and local controllable slow medicament release can be realized. At the same time, functions like imbibitions, ventilating and administration are realized. The preparation method has the advantages that the structure is simple; the molding technology is controllable; and automation and standardization can be realized easily. The size of the nasal insert, the aperture diameter and the porosity can be adjusted freely by changing the yarn thickness, the tension force, the loop number and the needle number. The appearance of the nasal insert is beautiful; and the nasal insert is targeted, practical and popular.

Description

technical field [0001] The invention relates to a single yarn medical multifunctional nasal plug and a preparation method thereof, belonging to the field of medical devices. Background technique [0002] Symptoms such as runny nose, nasal congestion, and nasal mucosa swelling and pain caused by rhinitis, sinusitis, and colds are very common in daily life, which brings a lot of trouble to people's life, study, and work. At present, there is no effective method to treat the symptoms of runny nose clinically. It can only be relieved by oral rhinitis medicine, sinusitis medicine or cold medicine, but the cycle is long, the effect is slow, and the most important thing is that the targeted treatment effect of the medicine is poor. After the drug enters the circulating blood of the human body, it not only acts on the nasal inflammation site, but also reaches other normal tissues and organs, and there are hidden dangers of side effects. Therefore, it is common for patients to stuf...
