Description

Detachable oxygen nasal plug

Technical Field

The utility model relates to a detachable oxygen nasal plug belongs to medical instrument, medical treatment consumptive material technical field.

Background

Nasal prongs are a device used to provide supplemental oxygen or airflow to a patient or person in need of respiratory assistance. Fig. 1 shows a prior art nasal cannula comprising a lightweight tube with two prongs separated in the middle and placed in the nostrils, and a mixture of air and oxygen flowing from the tube into the position of the prongs and out. The other end of the tube (not shown) is connected to an oxygen supply, such as a portable oxygen generator. Nasal cannulae are typically hooked over the patient's ears by the tube itself or secured to the patient by an elastic headband. These devices are effective at providing oxygen flow rates of 0 to 5 liters per minute when the patient is breathing spontaneously, and the nasal prongs need not be sealingly inserted into the nostrils of the user. When a patient needs to inhale through the nasal cannula, oxygen provided by the nasal cannula is inhaled into the patient along with the atmosphere through the nasal obstruction.

The existing nasal cannula has a great problem that: the nasal prongs of the cannula are often uncomfortable and may irritate the patient after prolonged use. Particularly, the aperture of the nasal plug is large, the aperture cannot be adjusted, and the nasal mucosa of a patient is impacted to cause discomfort when the oxygen flow is large, so that the nasal mucosa is easily damaged; the edges of the plastic material contained in the cannula may scratch or rub against the skin of the user's nostrils, causing rashes or cuts. In addition, the exit orifice of the cannula may concentrate the flow of oxygen, causing drying of the nasal tissue, which in turn may lead to epistaxis.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the detachable oxygen nasal plug is simple in structure, capable of ensuring the oxygen supply effect and reducing the impact damage of oxygen to nasal mucosa.

In order to achieve the above purpose, the utility model adopts the following design scheme:

a detachable oxygen nasal plug is a bent tube with a hollow tube cavity, one end of the bent tube is an air inlet end, the other end of the bent tube is an air outlet end, a groove is arranged at the air outlet end, and the outer side of the air inlet end is fixedly connected or integrally formed with an insertion piece. The design of the elbow can enable the gas flow to face the back of the nasal cavity of a patient, and effective oxygen supply is improved. The insert piece is used for inserting the air inlet end of the nasal plug into the straight-through air outlet of the nasal cavity intubation to form communicated sealing connection, so that air in the oxygen pipeline flows into the nasal plug.

The groove is open, and the area of the surface (the surface surrounded by the edge of the groove) of the groove is larger than the cross-sectional area of the pipe cavity at the air inlet end. The design can reduce the speed of the gas flowing out from the air outlet end of the nasal plug relative to the speed of the gas entering the air inlet end, thereby reducing the impact force of the gas on the interior of the nasal cavity and avoiding damage.

The surface of the groove is an arc surface, and the bending direction of the arc surface is consistent with that of the bent pipe.

In another embodiment, the groove is fixedly connected with a curved surface, and the curved surface is provided with more than 2 vent holes. The curved surface and the groove are connected in a seamless mode and can be manufactured in an integrated forming mode.

The vent holes are round holes with the diameter of 0.5-1mm, and the diameter can further control the strength of released airflow and further reduce the impact force of the air on nasal mucosa.

The pore canal pipeline of the vent hole is a straight line, a curve line or a broken line. The curved or broken line cavity conduit can change the direction of the gas flowing out, so that the gas is released in all directions, the local impact force is further relieved, and meanwhile, effective oxygen supply can be obtained in all directions of the nasal cavity of the patient.

The air outlet end of the bent pipe is slightly larger than the air inlet end. The shape is slightly larger, the volume of the air outlet end and the area of the air outlet position can be further increased by the design, the release range of the gas is expanded, and the oxygen supply effect is ensured.

The bent pipe is slightly bent relative to the straight pipe, and the bending degree of the bent pipe is consistent with that of the inside of the nasal cavity of the human body.

The edge of the groove is a smooth transition edge. Can effectively avoid scratching or scratching nasal mucosa.

The insert is an insert head end structure made of hard material, preferably a pagoda head. The fixing effect is better, and the falling is not easy. The insert may also be formed integrally with the elbow, for example from the same medical grade plastics material.

The outer surface of the elbow and/or the curved surface is provided with a hydrogel coating, so that the nasal cavity can be kept moist and comfortable.

The detachable oxygen nasal plug is made into a porous type, the impact force of oxygen on the nasal mucosa is decomposed, the nasal mucosa is protected while the oxygen flow inhalation is not influenced, in addition, when a patient needs a larger oxygen flow type, the porous nasal plug can be detached, and the oxygen flow is increased.

The detachable oxygen nasal plug is made of medical silica gel, rubber and plastic materials, has biocompatibility meeting the use standard of medical instruments or medical consumables, is suitable for being worn by a human body, reduces irritation to the human body, and improves the use comfort level.

The utility model discloses detachable oxygen nasal obstruction can have various models, size, pipe diameter and length, is fit for the patient of different age brackets and gender and selects the use.

The utility model has the advantages as follows: the design of the elbow can lead the gas flow to face the back of the nasal cavity of a patient, thereby ensuring the oxygen utilization effect; the outflow speed of the air outlet end of the nose plug is reduced relative to the speed of air entering the air inlet end, so that the impact force of the air on the inner part of the nasal cavity is reduced, the damage of oxygen impact on nasal mucosa of a patient is reduced, and the oxygen comfort level is improved. The detachable oxygen nasal plug is made into a porous type, so that the impact force of oxygen on nasal mucosa is further reduced, and the nasal mucosa is protected while the oxygen flow inhalation is not influenced. The oxygen nasal plug can be disassembled, and nasal plugs with different air outlet end structures can be adopted according to the requirements of patients, so that the supply of large-flow oxygen is met.
