Description

Technical Field

[0001] The utility model relates to the field of medical diagnosis, and more specifically, to a carbon dioxide collection nasal oxygen tube. Background Art

[0002] Oxygen inhalation is a very important medical technology, which is widely used in clinical departments, emergency departments, operating rooms, intensive care units, etc. Nasal oxygen cannula, which is commonly used in oxygen inhalation therapy, has received more and more attention. Oxygen supply through nasal oxygen cannula can increase arterial oxygen partial pressure (PaO2) and arterial oxygen saturation (SaO2), increase arterial oxygen content (CaO2), correct hypoxia caused by various reasons, promote tissue metabolism, and maintain the body's vital activities. The most common way of oxygen inhalation is for the patient to retain spontaneous breathing and use a nasal oxygen cannula to inhale oxygen through the nostrils. During use, the patient's inhaled oxygen concentration is increased to meet the oxygen supply demand. In the prior art, while providing oxygen inhalation, the carbon dioxide content in the patient's blood can also be monitored.

[0003] In the usual bedside monitoring and anesthesia recovery processes, the use of a nasal oxygen cannula to inhale oxygen through the nostrils (i.e., nasal oxygen supply) can basically meet the requirements. However, the proportion of oral oxygen inhalation in clinical patients is much larger than that of nasal oxygen inhalation, so nasal oxygen supply is not necessarily the best choice. Moreover, in the case of nasal congestion and lack of spontaneous breathing, as well as during gastroscopy, colonoscopy and surgery, the effect of nasal oxygen supply is greatly reduced, or even ineffective.

[0004] Therefore, it is necessary to develop a new device that can meet the oxygen inhalation needs in various situations and monitor the patient's respiratory status at the same time. Utility Model Content

[0005] The utility model aims to provide a carbon dioxide collection nasal oxygen tube, comprising a nasal tube unit, a carbon dioxide collection tube and a first oxygen supply tube respectively connected to the opposite sides of the nasal tube unit, and also comprising a second oxygen supply tube connected in parallel with the first oxygen supply tube for supplying oxygen to the oral cavity.

[0006] The second oxygen supply pipe and the first oxygen supply pipe are connected to the oxygen source pipeline through a three-way pipe.

[0007] The downstream of the carbon dioxide collection pipe is connected to a carbon dioxide monitoring device through a pipeline, and preferably may be provided with an alarm device.

[0008] Preferably, the carbon dioxide collection pipe is bundled together with the first oxygen supply pipe and the second oxygen supply pipe connected in parallel in the form of the three-way pipe through a two-way five-way pipe; in the two-way five-way pipe, the first oxygen supply pipe and the second oxygen supply pipe are connected to the oxygen source pipeline; the carbon dioxide collection pipe is connected to the pipeline of the carbon dioxide monitoring device.

[0009] Optionally, the carbon dioxide collection tube and the first oxygen supply tube are bundled together with a movable sleeve, and the movable sleeve is located between the two-way five-way tube and the nasal tube unit.

[0010] Preferably, the second oxygen supply pipe is provided with a flow regulating valve.

[0011] More preferably, the flow regulating valve is a flow cut-off valve.

[0012] Optionally, an oxygen outlet is provided at one end of the second oxygen supply tube for supplying oxygen to the oral cavity.

[0013] Further, the nasal tube unit comprises:

[0014] A base tube, one end of which is a carbon dioxide output end connected to the carbon dioxide collection tube, and the other end of which is an oxygen supply end connected to the first oxygen supply tube;

[0015] A collection end, which is arranged on the base tube and is connected to the carbon dioxide output end, and the collection end is arranged toward the nasal cavity to probe into the nasal cavity;

[0016] A plurality of oxygen supply holes are provided on the base tube and are connected to the oxygen supply end, and the plurality of oxygen supply holes are arranged toward the nasal cavity and / or the oral cavity;

[0017] The channel formed by the collection end and the carbon dioxide output end and the channels formed by the plurality of oxygen supply holes and the oxygen supply end are not connected to each other.

[0018] Preferably, the plurality of oxygen supply holes are arranged toward the nasal cavity.

[0019] Preferably, the nasal tube unit also includes a mask, which is externally connected to the base tube and arranged toward the oral cavity to reduce the escape of carbon dioxide.

[0020] More preferably, the mask has a mask chamber covering the periphery of the oral cavity or the periphery of the nasal cavity, and the mask chamber has a channel connected to the channel formed by the collection end and the carbon dioxide output end.

[0021] According to the technical content disclosed in the utility model, the following beneficial effects are achieved:

[0022] The carbon dioxide collection nasal oxygen tube provided by the utility model realizes real-time carbon dioxide monitoring and alarm while supplying oxygen to the nose by setting a parallel first oxygen supply tube and a carbon dioxide collection tube; in particular, a controllable second oxygen supply tube is set to realize oral oxygen supply. According to different clinical conditions, different options such as nasal oxygen supply alone, oral oxygen supply alone, and simultaneous oral and nasal oxygen supply are provided. It is particularly suitable for oxygen supply in cases of nasal congestion, lack of spontaneous breathing, and during surgery.

[0039] See also Figure 2 In the two-way five-way pipe 5, the first oxygen supply pipe 3 and the second oxygen supply pipe 4 are connected to the oxygen source pipeline 12; the carbon dioxide collection pipe 2 is connected to the pipeline 11 of the carbon dioxide monitoring device.

[0040] In this embodiment, the carbon dioxide collection tube 2 and the first oxygen supply tube 3 are bundled together by a movable sleeve 6 , and the movable sleeve 6 is located between the two-way five-way tube 5 and the nasal tube unit 1 .

[0041] In this embodiment, a flow regulating valve 9 is provided on the second oxygen supply pipe 4 for regulating the flow of oxygen input into the oral cavity.

[0042] In some preferred embodiments, the flow control valve 9 may be a flow cut-off valve so as to supply oxygen to the nasal cavity alone.

[0043] In this embodiment, an oxygen outlet 10 is provided at one end of the second oxygen supply tube 4 for supplying oxygen to the oral cavity.

[0044] In this embodiment, the pipeline 11 of the carbon dioxide monitoring device is connected to the carbon dioxide monitoring device (not shown in the figure) by a Luer connector 7. The oxygen source pipeline 12 is connected to the oxygen source (not shown in the figure) by an oxygen source connector 8.

[0045] See also Figure 3 and Figure 1 The nasal tube unit 1 of this embodiment includes a base tube 101, a collection end 102 and a plurality of oxygen supply holes 103.

[0046] One end of the base tube 101 is a carbon dioxide output end 104 connected to the carbon dioxide collection tube 2, and the other end is an oxygen supply end 105 connected to the first oxygen supply tube 3; the collection end 102 is arranged on the base tube 101 and is connected to the carbon dioxide output end 104, and the collection end 102 is arranged toward the nasal cavity for probing into the nasal cavity; a plurality of oxygen supply holes 103 are arranged on the base tube 101 and are connected to the oxygen supply end 105, and the plurality of oxygen supply holes 103 can be arranged toward the nasal cavity and / or the oral cavity.
