CN221905317U - A ventilable nasal balloon catheter stent - Google Patents

Abstract

The utility model relates to a ventilated nasal balloon catheter stent. The utility model adopts a balloon arranged on the catheter, and generates a supporting force on the nasal cavity after the balloon is inflated. Compared with the expansion sponge packing, the stent is more convenient to implant and more comfortable to use. The catheter can ensure that the nasal cavity is ventilated in the supporting state without affecting the patient's breathing. The balloon can be taken out after being deflated, which is convenient for doctors to examine the nasal cavity at a later stage; and by controlling the inflation amount of the balloon, the support strength of the balloon on the nasal cavity can be adjusted to meet the needs of different patients.

Description

A ventilated nasal balloon catheter stent

Technical Field

The utility model relates to the technical field of nasal brackets, in particular to a ventilated nasal balloon catheter bracket.

Background Art

Patients with structural rhinitis such as nasal septum deviation, middle turbinate bulla, and inferior turbinate hypertrophy need packing after surgery. The traditional method is to pack with expandable sponge, which can play a role in supporting, reshaping and hemostasis; mesh metal nasal stent is the latest treatment method for nasal disease packing.

In order to achieve good results, traditional nasal packing usually uses expanded sponges to fill the nasal cavity, causing the nasal cavity to be temporarily unable to ventilate, thus causing patients to have a series of symptoms such as headaches, nasal pain, nasal congestion, nasal itching, epiphora, and dysphagia. The removal process is often accompanied by secondary damage to the nasal mucosa, causing severe pain and other discomfort to the patient, seriously affecting the patient's quality of life during the postoperative recovery period. In the existing methods, when the nasal doctor examines, the nasal packing must be removed before the examination can be carried out, which increases the difficulty of the examination; and the support force of the mesh metal nasal stent is fixed, which is difficult to adjust according to the patient's needs and has low applicability.

Utility Model Content

In view of the problems existing in the prior art, the utility model discloses a nasal balloon catheter support capable of ventilation. The technical solution adopted is that a joint is fixedly connected to one end of a hollow catheter with openings at both ends, and a balloon is sealed and fixedly connected to the circumferential wall near the other end. The hollow channel of the catheter is an airway, and an inflatable channel is provided in the catheter in parallel with the airway. One end of the inflatable channel is located at the joint and communicates with the airway, and the other end is located at a corresponding position inside the balloon and opens on the outer wall of the catheter, so that the inflatable channel is communicated with the inner cavity of the balloon. An external air source from the joint can be used to inflate the balloon through the inflatable channel. An inflatable hole bolt is correspondingly installed at the opening where the inflatable channel communicates with the airway, and the inflatable hole bolt is threadedly installed on the joint. The opening and closing state of the inflatable hole between the inflatable channel and the airway can be adjusted by adjusting the inflatable hole bolt. The airway can ensure the support state of the balloon to the nasal cavity, and the connection between the nasal cavity and the outside world, which is convenient for the user to breathe.

As a preferred solution of the utility model, the balloon is made of any one of Pebax, Nylon or PET, has a length of 10-160 mm, and a diameter expansion range of 4-30 mm.

Beneficial effects of the utility model: the utility model adopts a balloon arranged on the catheter, and generates a supporting force for the nasal cavity by inflating the balloon. Compared with the expansion sponge packing, the stent is more convenient to implant and more comfortable to use. The catheter can ensure that the nasal cavity is ventilated in the supporting state without affecting the patient's breathing. The balloon can be taken out after being deflated, which is convenient for doctors to check the nasal cavity later; and by controlling the balloon inflation amount, the balloon's supporting force on the nasal cavity can be adjusted to meet the needs of different patients.
