Description

Nasal catheter of high-flow respiratory humidification therapeutic apparatus

Technical Field

The utility model relates to the field of medical equipment, in particular to a nasal catheter of a high-flow respiratory humidification therapeutic apparatus.

Background

The high flow respiratory humidification therapeutic instrument is an oxygen therapy mode and a respiratory support means for directly conveying air-oxygen mixed high flow gas with oxygen concentration to a patient through a nasal catheter. The therapeutic effects of HFNC (nasal high flow oxygen therapy) are: 1. the inhalation air is fully heated and humidified, so that the comfort and the tolerance of a patient can be improved, and the drainage and the discharge of secretion are promoted; 2. providing a stable inspired oxygen concentration; 3. the method has the advantages that the method can be used for scouring dead space, reducing repeated respiration of the upper airway anatomical dead space gas, obviously reducing the respiratory frequency along with the increase of flow rate, overcoming PEEPi (endogenous positive end expiratory pressure), reducing the load of inspiratory work done to indirectly influence the alveolar ventilation, and increasing VT (tidal volume) of COPD (chronic obstructive pulmonary disease); 4. protecting the mucous membrane of the air passage and enhancing the cleaning capability of the mucociliary. The nasal high-flow oxygen therapy is not only suitable for emergency treatment and intensive care units, but also can be popularized in general wards. However, the existing high-flow respiratory humidification therapeutic apparatus has the following defects:

1. the nasal plug tube presses the skin of the middle skin and the nasal septum skin of a person at the lower part of the nose to cause red pressing and ulceration, a layer of wet tissue or toilet paper needs to be padded for isolation to protect and prevent the skin from being pressed after long-term use, and due to factors such as turning over, the spacers are not firmly fixed and influence the appearance.

2. The high-flow hanging rope is thick and rough and is easy to press the skin of ears and cheeks after being worn for a long time, so that the skin is pressed red and damaged.

3. The plastic film pipeline at the front end of high flow often has cracks and air leakage, the material cost for replacing is high, and the common medical adhesive plaster is fixed again after the cracks.

It is therefore clear that the above-mentioned conventional nasal cannula for a high flow respiratory humidification therapy apparatus still has inconvenience and drawbacks in structure and use, and needs to be further improved. How to create a new nasal catheter of a high-flow respiratory humidification therapeutic apparatus belongs to one of the current important research and development subjects.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a humidifying therapeutic instrument nasal catheter is breathed to high flow makes it can avoid patient's skin pressurized, and adopts the protective material that the fixity is good, increases patient's comfort level and effectively protects nasal obstruction pipe opening part to overcome the not enough of present humidifying therapeutic instrument nasal catheter is breathed to high flow.

In order to solve the technical problem, the utility model provides a humidifying therapeutic instrument nasal catheter is breathed to high flow, including nasal obstruction pipe, the nasal obstruction body, hose and string rope, the other end and hose intercommunication are sealed to nasal obstruction pipe one end, the outer wall of nasal obstruction pipe outwards extends two columnar nasal obstruction bodies, be equipped with the venthole on the nasal obstruction body, the surface cladding aquogel of nasal obstruction pipe, the both ends outer wall connection of nasal obstruction pipe has a string rope, it is equipped with the sponge on the rope to hang, it makes the sponge can slide on hanging the rope to hang the rope from inside passing of sponge to hang the rope.

As an improvement of the utility model, the hydrogel is coated on the outer wall of the attaching side of the nasal obstruction tube and the human body, the hydrogel is rectangular after being unfolded, and the length of the hydrogel is the same as that of the nasal obstruction tube.

Furthermore, the hanging rope is made of pure cotton.

Furthermore, the hose is made of a high polymer material.

Furthermore, the nasal plug tube is made of medical silica gel.

After adopting such design, the utility model discloses following advantage has at least:

1. the nasal plug tube adopts medical silica gel, the outer wall of the nasal plug tube is coated with hydrogel, and the nasal plug tube can effectively relieve the compression on the skin of the middle nasal septum part of a person caused by long-time wearing, and can promote wound healing if the skin of the middle nasal septum part of the person or the skin of the nasal septum part of the person is broken.

2. The hanging rope is made of pure cotton materials and the sponge with the adjustable position is arranged on the hanging rope, so that the positions of two sides of the ears are protected, and the comfort of a patient during wearing can be improved.

3. The hose is made of high polymer materials, so that the hose is stronger in fixity and not easy to damage, and the service life is prolonged.
