In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the following specific embodiments.
As shown in fig. 1, an end-tidal carbon dioxide collection and oxygen inhalation device comprises a device body 1 and inhalation components which are arranged corresponding to two nasal cavities; the device body 1 is provided with an oxygen inhalation channel 2 and an end-expiratory carbon dioxide collection channel 3; the suction assembly is connected with the device body 1; any one of the suction and extraction components comprises an oxygen inhalation tube 4 and a collection tube 5; the oxygen inhalation tube 4 is communicated with the oxygen inhalation channel 2; the collection tube 5 is communicated with the end-tidal carbon dioxide collection channel 3.
In the prior art, the general device body 1 is provided with an oxygen inhalation tube 4 and a collecting tube 5, wherein the oxygen inhalation tube 4 stretches into one nasal cavity of a patient, and the collecting tube 5 stretches into the other nasal cavity of the patient, so that unilateral oxygen supply and unilateral end-expiratory carbon dioxide collection are formed. It is therefore clear that the drawbacks associated with this are insufficient oxygenation and insufficient capture of end-tidal carbon dioxide.
Thus, in this embodiment, bilateral nasal delivery of oxygen and end tidal carbon dioxide collection are achieved to fully provide oxygen to the patient and to fully collect end tidal carbon dioxide.
In some embodiments, as shown in fig. 2, in any one of the inhalation modules, the oxygen inhalation tube 4 and the collection tube 5 extend out of the device body 1 and are arranged at an angle, and both open towards the outside of the device body 1.
In the prior art, in order to further improve the oxygen supply efficiency and the end-tidal carbon dioxide collection efficiency, a component for an oral cavity is additionally arranged, but in this way, for a patient with general anesthesia, the functional effect is not high, and air leakage, especially the collected end-tidal carbon dioxide is easily caused to be lost.
It is known that the device itself is generally made of a relatively soft plastic material, which has a certain deformability, so that when the oxygen tube 4 and the collection tube 5 are arranged at an angle, any one of the inhalation assembly can be fixed in the corresponding nasal cavity in a manner similar to the manner of opening the nasal cavity, thereby achieving the effect of stabilizing the device.
As shown in fig. 3, in this embodiment, any one of the suction and extraction assemblies further includes a hollow nasal plug 6 matched with the nasal cavity, and the nasal plug 6 is connected with the device body 1; the oxygen inhalation tube 4 and the collection tube 5 are both positioned in the device body 1 and are communicated with the inside of the nasal plug 6.
The medical staff can directly stretch the nasal plug 6 into the nasal cavity of the patient so that the oxygen inhalation tube 4 and the collection tube 5 are positioned at the positions acting on the nasal cavity of the patient, thereby realizing the functional effects of the oxygen inhalation tube 4 and the collection tube 5.
In this embodiment, the oxygen tube 4 and the collection tube 5 may be disposed at an open angle, a closed angle, or parallel to each other.
Further, in the present embodiment, the nose plug 6 gradually increases in inner diameter from the end near the device body 1 to the end far from the device body 1.
The nose plug 6 is of a hollow frustum structure, the inner diameter of one end of the connecting device body 1 is small, and the inner diameter of one end of the connecting device body far away from the device body 1 is large, so that the nose plug 6 can be well clamped in a nasal cavity, and the fixing requirements of the oxygen inhalation tube 4 and the collection tube 5 are met.
In any one of the inhalation assembly, the oxygen inhalation tube 4 is of a semicircular structure and is communicated with the inner side of the nasal obstruction 6. As shown in FIG. 3, the collecting tube 5 is of a semi-horn structure and is communicated with the outer side of the nasal obstruction 6
In this embodiment, the two oxygen inhalation tubes 4 are close to each other and the two collection tubes 5 are far from each other.
Of course, in some embodiments, the arrangement opposite to the present embodiment may be performed, that is, the oxygen inhalation tube 4 is attached to the outer side of the nasal plug 6, the collecting tube 5 is attached to the inner side of the nasal plug 6, and at this time, the two oxygen inhalation tubes 4 are far away from each other, and the two collecting tubes 5 are close to each other.

It is also known that the above-described arrangement is also adopted in the embodiment in which the oxygen tube 4 and the collection tube 5 extend out of the device body 1.
For better use of the present embodiment, the nasal plug 6 is provided with a partition 7 for dividing the nasal plug 6 into two parts, one for oxygen delivery and the other for carbon dioxide end expiration collection.
In this embodiment, the nasal plug 6 is divided into two parts by the partition 7, and may be equally divided or unevenly divided, so as to meet the requirements of fully supplying oxygen and fully collecting end-tidal carbon dioxide.
For better use of the present embodiment, further comprising a first long tube and a second long tube; the first long tube is communicated with the oxygen inhalation channel 2, and is connected to oxygen supply equipment; the second long tube is communicated with the end-expiratory carbon dioxide collecting channel 3, and the second long tube is connected to end-expiratory carbon dioxide monitoring equipment.
The first long tube and the second long tube encircle the head of the patient, so that the device is integrally sleeved on the head of the patient, and the fixing requirement is met.
In this embodiment, the first long tube is specifically connected to an oxygen bottle, and the second long tube is specifically connected to a respirator or a monitor.
Therefore, through the embodiment, the vital sign monitoring of the patient with the general anesthesia cannula in the resuscitation period or the patient without the general anesthesia cannula can be better and more timely realized, and the patient can realize more sufficient oxygen inhalation.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that the above-mentioned preferred embodiment should not be construed as limiting the utility model, and the scope of the utility model should be defined by the appended claims.
