Abstract
A kind of novel oxygen uptake is with nose cup (5), mainly it is made of gas source connector (1), main pipe (2), adapter (3), brasnch conduct (4), nose cup (5), the use mask designs of oxygen therapy pipeline front end gas outlet, overcome existing nasal oxygen tube and mask existing many defects in oxygen therapy, patient comfort is improved, the oxygen consumption of mask oxygen-inspiration is reduced.Meanwhile during oxygen therapy, the catheter retaining mouth (7) of nose cup (5) lower edge makes to be inserted into through Nasal gastrointestinal tube or indwelling fixation is more convenient and firm.
Description
Technical field
The present invention relates to a kind of novel oxygen uptake nose cups, belong to the medical instrument scope that hospital clinical uses.
Background technique
Oxygen uptake is the oxygen flow provided according to oxygen therapy scheme for anoxic or the most common treatment means of recovery patient
Difference selects the main consumptive material of nasal oxygen tube or mask as oxygen therapy.Common nasal oxygen tube is according to the shape and use of front end gas outlet
Way difference is divided into single nasal obstruction, two kinds of ∏ shape nasal oxygen tube.
Common oxygen therapy patient generally uses ∏ shape nasal oxygen tube, but via intranasal application indwelling gastric tube patient simultaneously is needed when oxygen therapy,
It must be using single nasal obstruction nasal oxygen tube.Nasal oxygen tube is easy to use, cost economy.But nasal oxygen tube is generally only suitable for low discharge oxygen supply, if
Flow is bigger to allow people that can not be resistant to greatly very much because of flow velocity and impact force, cause nose is uncomfortable, nasal membrane is dry even to open
Split bleeding.It exists simultaneously nose to be easy to be blocked by nasal mucus, the shortcoming such as not easy to clean.
Mask oxygen-inspiration method be cup is closely covered in into snout and is fixed with elastic band, its advantage is that patient's sense of discomfort compared with
It is few, no mucosal irritation and dry blow feeling.But the disadvantage is that oxygen consumption is 1-2 times bigger than nasal oxygen tube, and there are patients during oxygen therapy
Communication, feed or expectoration etc. are all many-sided inconvenient, and patient compliance is also poor；And oral, nose indwelling gastric tube
Patient is not available, and there are clinical limitations.
For this purpose, present inventor proposes a kind of novel oxygen uptake nose cup, fills up this according to long-term clinical observation and practice
The clinical blank of kind medical material.
Summary of the invention
The invention proposes a kind of novel oxygen uptake nose cups, are mainly led by gas source connector, main pipe, adapter, branch
Pipe, nose cup composition, are mainly characterized by comprising:
The gas source connector, which refers to, to supply any shape interface that source port is connected to oxygen, using the medical height of elasticity
The sub- material injection technique preparation of molecule.
The main pipe, brasnch conduct are that oxygen conveys the soft pipeline passed through, and lower end and the gas source of main pipe connect
Head is bonded and is connected to, and main pipe upper end is connected to by adapter with brasnch conduct；Main pipe, brasnch conduct use soft polychlorostyrene second
The preparation of the medical macromolecular materials extrusion process such as alkene, silica gel.
The nose cup is pear shape, and nose cup can integrally coincide with user's nose exterior contour；The lower edge of nose cup is equipped with
Skirt simultaneously coincide with the musculus orbicularis oris surface of human body upper lip substantially, the left and right sides of nose cup be equipped with skirt and with human body wing of nose two sides
Nasalis surface coincide substantially；The front of nose cup swells and forms internal cavities, and specific requirement is: nose cup can be by human nasal head position
It loosely covers in the cavity of protuberance, the lower edge of nose cup and nostril should at least keep 5mm spacing；It is defined according to different target users
Nose cup external dimensions, nose cup is using the sub- material injection technique preparation of elastic medical high polymer.
Described brasnch conduct one end is connected to main pipe, is connected to inside the other end and nose cup, brasnch conduct and nose cup
Connecting portion is unlimited.Preferable scheme is that: the connects with the internal cavities of brasnch conduct and nose cup protuberance, connection position are arranged in nose cup
Swell the left and right sides, the brasnch conduct air inlet landscape layout of cavity；Further optimize, the interconnecting part of brasnch conduct and nose cup
Position is disposed proximate at the lower edge of nose cup, air inlet, landscape layout at left and right sides of brasnch conduct.The outer wall of nose cup is equipped with exhaust outlet,
Exhaust outlet is arranged on the outer wall of nose cup, the internal cavities perforation of exhaust outlet and nose cup.Exhaust outlet is generally 1-2, and setting exists
The left and right sides of nose cup front ridge or nose cup；Preferable scheme is that the front protrusion of nose cup is arranged in exhaust outlet
Position.Check valve can also be set on exhaust outlet, and check valve is specially that can be closed or open exhaust outlet under airflow function
Diaphragm.
The position of the lower edge of nose cup face vertical with nostril is additionally provided with 1-2 and stays for the conduit being inserted through through Nasal gastrointestinal tube
Mouth is set, the size shape of catheter retaining mouth is matched with matching used through Nasal gastrointestinal tube；It is additionally provided on the outside of catheter retaining mouth
Corresponding lid, lid is in normally off when oxygen uptake, needs to be inserted into through opening lid when Nasal gastrointestinal tube.It is clear that nose
The lid of the catheter retaining mouth of the lower edge of cover can also use silica gel, latex or the more simple mode of soft pvc elastomeric material
Preparation, concrete scheme are that catheter retaining mouth is prepared into 0.5mm-1mm using elastic medical macromolecular materials by catheter retaining mouth
Film, and a word or cross are scratched on film；Catheter retaining mouth is under the elasticity tension effect of film, catheter retaining mouth
It is in Natural closure state in oxygen therapy, effectively prevent oxygen evolution waste, needs to be inserted into through can effectively pass through when Nasal gastrointestinal tube
Conduit simultaneously includes pipe shaft, facilitates the fixation through Nasal gastrointestinal tube.
The beneficial effects of the present invention are: the use mask designs of (1) oxygen therapy pipeline front end gas outlet, had both overcome existing nose
The disadvantages of oxygen pipe gas shock nostril bring compliance is poor, nose is not easy to clean, but it is existing in oxygen therapy to overcome mask
Many defects such as oxygen utilization degree is poor, feed and speech exchange inconvenience, improve patient comfort, reduce the oxygen of mask oxygen-inspiration
Gas consumption.(2) when application oxygen therapy of the present invention, due to hot gas (the predominantly CO of patient's exhalation2) than the cold air (O of entrance2) density
Small, upward ascension generates draught head, and the left and right sides of the oxygen from nose cup close to lower edge enters inner cavity, promote air-flow be produced from down and
On flowing (namely stack effect), the CO of exhalation2It is breathed out from exhaust outlet, CO2It is difficult to be detained inside nose cup, effectively avoid
CO2It is sucked without repetition.(3) during oxygen therapy, the catheter retaining mouth of nose cup lower edge makes to be inserted into through Nasal gastrointestinal tube or indwelling is fixed more
It is convenient and firm to add.(4) manufacturing cost of the invention is low, technical maturity, and suitable clinic is widely popularized.
