Description

Nasal catheter capable of automatically adjusting oxygen flow
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to automatic nasal catheter of adjusting oxygen flow.
Background
The nasal oxygen inhalation tube has very important treatment effect in clinic, is usually used for treating patients and has the effects of improving blood oxygen concentration and the like.
However, the existing nasal catheter has simple function, does not have the capability of automatically adjusting the oxygen flow, and simultaneously cannot adjust the oxygen delivery amount according to the breathing condition of a patient, so that a large amount of oxygen sources are wasted, and potential safety hazards also exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automatic nasal catheter of adjusting oxygen flow to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model adopts the following technical scheme: a nasal catheter capable of automatically adjusting oxygen flow comprises a nasal catheter and an oxygen bottle which are matched with each other, wherein the nasal catheter comprises an air inlet pipe for air suction of a patient and an exhaust pipe for exhaust of the patient;
the nasal catheter is provided with an air vent between the air inlet end of the air inlet pipe and the air outlet end of the control valve, and the air outlet end of the air vent is provided with an on-off valve;
the gas monitoring device comprises an oxygen concentration monitoring sensor and a controller, wherein the controller is respectively connected with the control valve and the opening and closing valve through electric signals.
The utility model discloses a nasal catheter simple structure, in the use, through what of oxygen content among the oxygen concentration monitoring sensor real-time supervision patient exhalation gas to judge patient's expiration state, through controller control valve, with the volume that this automatically regulated control oxygen was carried, thereby practice thrift oxygen, breathe normal back at the patient, through the setting of blow vent, the operating condition of simultaneous control valve, opening and closing valve makes between blow vent, the intake pipe form the route.
Preferably, the exhaust end of the gas monitoring device is provided with a filter screen for filtering gas exhausted by the patient.
Preferably, one end of the air vent far away from the nasal catheter is provided with a filter screen for filtering the gas exhausted by the patient and the gas inhaled by the patient.
Preferably, the gas inlet sleeve of the gas monitoring device is arranged at the exhaust end of the exhaust pipe, so that the gas monitoring device is convenient to replace.
The utility model has the advantages that:
the utility model discloses a nasal catheter simple structure, in the use, through what of oxygen content in the patient's expired gas, the volume that automatic adjustment control oxygen was carried to practice thrift oxygen.
Description of the drawings:
fig. 1 is a schematic sectional structure of the present invention;
description of reference numerals:
1. the nasal catheter comprises a nasal catheter 11, an air inlet pipe 12, an exhaust pipe 2, an oxygen delivery bottle 3, a gas monitoring device 31, an oxygen concentration monitoring sensor 32, a controller 33, a filter screen 4 and a control valve.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the nasal cannula capable of automatically adjusting oxygen flow of the present invention comprises a nasal cannula 1 and an oxygen bottle 2 which are matched with each other, wherein the nasal cannula 1 comprises an air inlet tube 11 for patient inhalation and an air outlet tube 12 for patient exhaust, the air outlet end of the air outlet tube 12 is provided with a gas monitoring device 3, and a control valve 4 for controlling oxygen flow is arranged between the nasal cannula 1 and the oxygen bottle 2;
a vent is arranged between the air inlet end of the air inlet pipe 11 and the air outlet end of the control valve 4 of the nasal catheter 1, and an opening and closing valve is arranged at the air outlet end of the vent;
the gas monitoring device 3 comprises an oxygen concentration monitoring sensor 31 and a controller 32, wherein the controller 32 is respectively connected with the control valve 4 and an electric signal of the opening and closing valve.
When the nasal catheter is implemented, the air inlet pipe 11 and the air outlet pipe 12 of the nasal catheter 1 are respectively inserted into the nostrils of a patient, oxygen output from the oxygen bottle 2 reaches the nasal cavity of the patient through the air inlet pipe 11, so that the patient can breathe normally, the exhaled air of the patient is exhausted along the air outlet pipe 12, the oxygen concentration monitoring sensor 31 at the air outlet end of the air outlet pipe 12 monitors the content of oxygen in the exhaled air of the patient in real time, monitored data are fed back to the controller 32, the range value of the oxygen content in the normal exhaled air of the patient is stored in the controller 32, the monitored oxygen content in the exhaled air of the patient is compared with the oxygen content in the normal exhaled air, so that the exhalation state of the patient is judged, the controller 32 controls the control valve 4 by the aid of the controller, the flow of oxygen entering the nasal catheter 1 is adjusted, the oxygen conveying amount is automatically adjusted and, the controller 32 controls the control valve 4 to adjust the amount of oxygen supplied to the nasal cavity of the patient to zero, and controls the open/close valve to form a passage between the ventilation port and the intake tube 11, thereby achieving free breathing of the patient.
As a preferable mode of the above embodiment, in order to filter the gas exhausted from the patient through the exhaust pipe 12, the exhaust end of the gas monitoring apparatus 3 is provided with a filter screen 33 for filtering the water vapor in the gas exhausted from the patient.
In a preferred embodiment of the above embodiment, when the patient breathes normally, a filter screen is provided at one end of the ventilation port away from the nasal cannula for filtering the patient's exhaust gas and inhaled gas.
As a preferable solution of the above embodiment, in order to facilitate replacement of the gas monitoring device 3, the gas inlet of the gas monitoring device 3 is sleeved on the exhaust end of the exhaust pipe 12.
The above embodiments only represent the specific embodiments of the present invention, and the description thereof is specific and detailed, but it cannot be understood as the limitation of the patent scope of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and all of them belong to the protection scope of the present invention.
