Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a device for monitoring carbon dioxide at the end of breath through nose.
Background
The end-tidal carbon dioxide partial pressure refers to the carbon dioxide concentration in the exhaled gas, and the end-tidal carbon dioxide monitoring is a noninvasive, simple, real-time and continuous functional monitoring means, has high sensitivity, can monitor ventilation and reflect the circulation function and the pulmonary blood flow condition, and is an indispensable conventional monitoring means for anesthesia detection at present.
For example, the authorized bulletin number is: CN213609138U, authorized bulletin day: in 2021, utility model patent 7 and 6, disclose a can monitor breathe end carbon dioxide's nasal oxygen inhalation tube, including connecting block, oxygen inhalation tube, breathing tube, adapter sleeve and sponge layer, the bottom fixed mounting of connecting block has first nasal plug and second nasal plug, open the exhaust hole in first nasal plug and the second nasal plug, in this utility model file, can realize through this device that the patient is nasal to give oxygen and through detecting breathe end carbon dioxide wave form and frequency simultaneously, monitor patient's respiratory function.
The authorized bulletin number is: CN210963461U, authorized bulletin day: in the utility model patent of 7 months and 10 days in 2020, a novel oxygen inhalation tube with a breath end carbon dioxide monitoring function is disclosed, the novel oxygen inhalation tube comprises a horn joint, an oxygen therapy tube, a three-way tube, an upper branch tube, a lower branch tube, a nasal obstruction, a breath end carbon dioxide monitoring branch tube, a gas reversing device, wherein the nasal obstruction comprises an upper transition tube, a lower transition tube and two nasal cannulas, the gas reversing device comprises a valve body, a valve cavity arranged in the valve body and an adjusting airway sealing device arranged in the valve cavity, and the novel oxygen inhalation tube can be suitable for monitoring the concentration of breath end carbon dioxide by adjusting the airway sealing device.
The main disadvantages of the prior art are focused on three aspects: one is that the patient does not breathe spontaneously during the period of general anesthesia induction, and an anesthesiologist ensures ventilation of the patient through a mask for oxygen supply, so that the added oxygen therapy tube part has limited effect on the patient with general anesthesia; the length of the second conduit is too long, which is easy to cause intertwining with the wiring or cause the operation area of anesthesiologists to be limited, even touch the sterile area; three such devices are costly. Thus, in such devices, the oxygen catheter portion may be eliminated, depending on the actual clinical application at hand (mask oxygen delivery during general anesthesia induction).
Disclosure of Invention
The utility model aims to overcome the problems and provide a device for monitoring carbon dioxide at the end of breath through nose, which adopts the following technical scheme:
the nasal monitoring device for monitoring the carbon dioxide at the end of breath comprises a detection tube and a receiver, wherein the detection tube comprises a double-cavity nasal catheter and a connecting catheter, and the receiver is connected with a joint of a monitor.
Further, the inner diameter of the double-cavity nasal catheter is 1.25-1.45 mm.
Further, the length of the double-cavity nasal catheter is 10+/-1 mm.
Further, the inner diameter of the connecting catheter is 1.5-1.8 mm.
Further, the length of the connecting conduit is 30+/-1 cm.
Further, the receiver is connected with the monitor through threads.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model can remove the oxygen catheter part under the condition of ensuring oxygenation of general anesthesia patients in the prior art, reduces the whole length of the catheter, has small volume and simple structure, and is changed into a double-cavity nasal catheter which is directly connected with a monitor through a shortened single-channel connecting catheter connecting receiver, thereby being convenient to operate, providing a clean, convenient and quick operation area for anesthesiologists, reducing potential pollution risks in the treatment and use process, simultaneously, the removed oxygen catheter part can reduce the production cost and raw material waste of the traditional product manufacture, and also saves the treatment expense for patients.
