Medical oxygen means oxygen which is used for medical treatment and treatment of patients by separating oxygen in the atmosphere by a cryogenic separation method. Generally, the bottled medical oxygen is delivered to various medical places in a bottled mode, the national standard of purity of the bottled medical oxygen is more than or equal to 99.5%, the carbon dioxide content, the carbon monoxide content, the pH value, the gaseous oxide and the like in the bottled medical oxygen are strictly limited, and most of the bottled medical oxygen is pressurized and directly delivered to the nasal cavity of a patient through a pipeline.

The existing pipeline is made of transparent plastic materials, and two outlets are arranged to be directly opposite to nostrils, so that the patient can conveniently breathe; however, because the inner diameter of the pipeline is usually small, noise is easy to generate when the pressurized gas is conveyed, and the noise affects patients in a ward. If the oxygen flow is adjusted to be small, although the noise can be reduced, the requirement of oxygen inhalation of patients cannot be met.

In addition, after the oxygen supply valve is opened for a patient requiring oxygen therapy, oxygen is continuously supplied to the patient until the doctor confirms that oxygen is no longer required. In practice, the patient does not always wear the oxygen supply device during the oxygen supply process, or more specifically, the patient exhales, the oxygen supply is wasted and cannot be absorbed by the patient, which results in waste of resources.

Although the valve is adopted to close the oxygen supply pipeline in the oxygen supply process, if the patient does not use the oxygen supply switch which can close the body side temporarily; but the oxygen supply wasted in expiration cannot be saved. This waste is not significant for an individual, but is significant to integrate the supply of oxygen to all patients. Therefore, in order to save resources, it is necessary to develop a medical oxygen apparatus which can avoid waste.

In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

As shown in fig. 1, a medical oxygen hose comprises a hose body 1, a transition hose 2 and two nose insertion hoses 3, wherein the hose body 1 is connected with the transition hose 2, the transition hose 2 is radially communicated with the two nose insertion hoses 3, and the inner wall of the joint of the nose insertion hose 3 and the transition hose 2 is of a smooth transition arc structure.

In traditional medical oxygen pipe, the junction inner wall of transition pipe 2 and nose pipe 3 is the right angle type, and the pressure oxygen of sending into is when passing through here, takes place the torrent phenomenon easily, causes local air velocity too fast the sound of appearing. This product is through improving the inner wall structure of this junction, for glossy transition arc structure, and the air current is difficult for appearing the torrent phenomenon here, wholly is in laminar flow state, has reduced the condition that produces the noise.

Further, the inner diameters of the transition tube 2 and the nose-inserting tube 3 are both larger than the inner diameter of the tube body 1. Increase the internal diameter size of transition pipe 2 and nose inserting pipe 3, especially be greater than the internal diameter of body 1 for the air current gets into transition pipe 2 by body 1 and when inserting the nose pipe, the cross section enlarges, and the whole velocity of flow reduces, and the smooth transition arc structure of the transition pipe 2 of reunion and 3 junctions of nose inserting pipe, the probability greatly reduced that the air current produced the noise.

The internal diameter of tradition oxygen hose is 6 ~ 10mm, and the internal diameter of body 1 maintains traditional size in this product, and the internal diameter of transition pipe 2 and nose pipe 3 enlarges, sets up to 10 ~ 12 mm. The cross section area of transition pipe 2 can enlarge 4 times for body 1 at most like this, and the air current gets into transition pipe 2 speed reduction in the twinkling of an eye, gets into nose tube 3 quite slowly, can not appear the noise.

Because the internal diameter of transition pipe 2 is greater than body 1 internal diameter, the air current is in the moment of getting into transition pipe 2, and the cross section takes place to enlarge in the twinkling of an eye, causes the air current local instability easily, takes place the torrent, consequently adds gas permeability filler 21 in transition pipe 2 for cushion the unstable phenomenon of air current that the sectional area that suddenly changes caused, ensures the air current of flowing through filler 21 steady diffusion.

Preferably, the air-permeable filler 21 has a porosity of 63% to 83%, and is a solid filler such as large-pore activated carbon. The filling of the air-permeable filler may be partial filling, as shown in fig. 2, or the transition duct 2 may be filled entirely.

The transition pipe 2 is filled with air-permeable substances, and the substances play a role in stabilizing the air flow due to the large porosity of the filler, and can also filter the air flow to filter partial impurities or hazards.

The traditional oxygen delivery process is continuous delivery, namely bottled oxygen can be always sent to the outlet of the nasal cannula 3 after the valve is opened, no matter what state the patient is in, such as expiration or temporary extraction of the nasal cannula 3, and thus the delivered oxygen cannot work and is wasted.

This product sets up temperature-sensing ware 31 on inserting nasal tube 3, utilizes the temperature of exhaled air and the oxygen temperature that sends into to have the difference, and the temperature of exhaled air is the body temperature generally, as long as sense the expired gas temperature, or exceeds and send into the oxygen temperature, and steerable oxygen therapy equipment suspends the air feed, and certainly to temporarily pulling out inserting nasal tube 3, more clearly when going to suspend the air feed.

The temperature sensor 31 is provided not only to provide a time-out effect, but also to monitor the temperature of the patient.

The temperature information detected by the temperature sensor 31 can be connected with the oxygen pipeline control valve through a controller in a wired mode, and the temperature change range and the corresponding relation of the control valve switch are set in the controller; such techniques are common operations in electronic control devices, and are described in detail herein.

Preferably, this product has adopted and has set up temperature-sensing valve 4 on body 1, temperature-sensing valve 4 through the controller with temperature-sensing ware is connected. The temperature control valve 4 is of an electric type, and automatically controls opening and closing of the valve according to temperature change based on a set temperature range.

Because the body 1 of oxygen hose all communicates with the both ends of transition pipe 2 usually, in the position that sets up temperature-sensing valve 4, the position of selecting to be located the main body, neither influences patient's normal use, can play the switch effect again well.

By combining the temperature sensor 31 with the temperature controller 4, the oxygen delivery can be selectively turned on or off, such as air supply when the patient inhales and pause when the patient exhales, thereby saving the oxygen supply.

In order to ensure the stability of oxygen delivery of the product, the smooth joint of the transition pipe 2 and the nose insertion pipe 3 is particularly important, so that the transition pipe and the nose insertion pipe are molded by injection once in manufacturing, the smooth degree of the inner wall of the joint is high, the airflow stability is good, and noise is difficult to generate.

And for pegging graft between body 1 and the transition pipe 2, especially, the activity is sealed and pegs graft, transition pipe 2 and the integrative structure of inserting nose pipe 3 like this, because insert nose pipe 3 and patient contact, after conventional oxygen therapy accomplished, even take body 1, transition pipe 2 and insert nose pipe 3 and handle as medical waste, and body 1 and transition pipe 2 are for pegging graft in this product, and make transition pipe 2 longer than traditional structure, avoid body 1 and patient to contact, just use transition pipe 2 and insert nose pipe 3 of integrative structure as the consumptive material like this, and body 1 itself is as general type material, can repetitious usage, the condition of just abandoning after having avoided disposable, medical waste has been reduced simultaneously, resources are saved.

In addition, in the preparation, but the gas permeability filler of adding as required in the transition pipe 1, body 1 adopts the grafting mode with transition pipe 2 to be connected, and the interpolation of gas permeability filler can not receive the influence of body 1, therefore the preparation is convenient easy.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
