Description

Nasal plug

Technical Field

The invention relates to the technical field of nasal obstruction articles, in particular to a nasal obstruction.

Background

At present, the circulating nasal plug used after operation in the market is generally a water injection expansion type nasal plug which hardly ventilates and completely blocks nostrils, so that a patient can only breathe by mouth for a long time. In addition, according to the shape of the nostrils, the existing nasal plug is almost directly pulled out after being worn for three to five days, and when the nasal plug is pulled out under the condition of expansion, a patient feels very uncomfortable.

The nasal obstruction for the postoperative of circulation on the market at present is water injection inflation class nasal obstruction usually, and moist environment is difficult for forming the blood scab, is unfavorable for the hemostasis of incision in the nostril, and moist environment breeds the bacterium more easily moreover, has increased the risk of postoperative infection, is unfavorable for the healing of incision. In addition, water may evaporate, especially in warmer environments, resulting in a gradual reduction in the nasal prong support force.

Disclosure of Invention

Therefore, the invention provides a nasal plug, which aims to solve the problems that the nasal plug in the prior art adopts a water injection expansion type nasal plug to cause the increase of the risk of postoperative infection and is not beneficial to the healing of an incision.

Detailed Description

The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to an embodiment of the invention, there is provided a nasal plug, as shown in fig. 1 to 3, comprising a catheter 11 and a balloon 12, wherein a through hole 111 is formed in the length direction of the catheter 11, the balloon 12 wraps the catheter 11 along the circumference of the catheter 11, the balloon 12 is filled with air, and the pressure inside the balloon 12 is adjustable. The through hole 111 is located at the center of the catheter 11, the nasal plug further comprises an inflation valve 13, the inflation valve 13 is connected with the air bag 12, and the air bag 12 is inflated or deflated through the inflation valve 13.

The nasal plug provided by the invention does not need water injection in the using process, ensures a dry environment, reduces the infection rate, permanently increases the supporting effect and reduces the formation of secretion at the incision; in addition, the ventilation function of the nostrils of the patient can be obviously improved by arranging the through holes 111, so that the comfort is better; the nasal plug is in an oval shape and is close to an arch shape, and the arch structure can fill the nostrils in an all-around manner by utilizing the principle of pressure intensity generated by aerodynamic force, and the highest pressure of the fornix of the nasal cavity is stronger, so that the nostril shaping effect is more perfect. When the nasal plug after the operation needs to be pulled out, air can be discharged from the air bag, the size of the air bag is reduced, then the nasal plug is pulled out, and the experience of customers is better.

The through hole 111 is cylindrical and has a diameter of 0.4 cm to 0.6 cm. The length of the through hole 111 is 2.5 cm. The diameter of the through hole 111 may be determined according to the size of the nostril of the patient, the diameter of the through hole 111 may be 0.6 cm for a patient with a larger nostril, the diameter of the through hole 111 may be 0.4 cm for a patient with a smaller nostril, or the diameter of the through hole 111 may be 0.5 cm, and these dimensions are determined according to the physiological characteristics of the patient.

The material of the air bag wall of the air bag 12 is skin-friendly material, such as latex, especially natural latex, which is relatively soft, has little stimulation to the skin, has certain elasticity, and can improve the comfort when contacting with the skin of a human body.

The conduit 11 is made of plastic. The plastic may be a PVC material. Has certain rigidity and supporting force and forms support for the nostrils of the patient.

The nasal prong also includes a clip (not shown) for closing the inflation valve 13, which can be directly attached to the inflation valve 13 to prevent air pressure changes in the air bag when inflation or deflation is not required.

When in use, the two nasal plugs can be respectively plugged into the nostrils of a patient after operation, and the nostrils of the patient are supported and protected by the nasal plugs.

Wherein the pressure in the bladder 12 is variable, the pressure in the bladder 12 can be selected as desired.

The material of the air bag 12 is an expanding sponge. At this time, the air bag can be replaced by solid expanded sponge, which can support the nostril and adapt to the nostril shape of the patient. Instead of gas, the air bag 12 may be filled with liquid, and in this case, the inflation valve 13 may be changed to a liquid valve.

The conduit 11 is in the shape of a shuttle or an ellipse. Of course, the catheter 11 is externally wrapped by the balloon 12, and the catheter 11 may be implemented in other shapes, such as a hollow truncated cone shape or a hollow cone shape.

The nose plugs are in an axisymmetric structure, and when the nasal plug is used, the two nose plugs are used for respectively plugging the two nostrils. The nasal plug is designed into an axisymmetric structure, is matched with the shape of the nostril of a person, can be fully filled in the nostril and forms a support for the nostril.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
