Description

Breathing circulation tube having membrane structure {Breathing Circulation Tube having Membrane Structure}

The present invention relates to a respiratory circulation tube having a membrane structure, and more particularly, by improving the structure heated in the respiratory circulation tube for supplying anesthetic and oxygen to a patient, uniformly transferring heat as a whole, and passing the membrane through a microchannel inside the tube. It relates to a respiratory circulation tube having a membrane structure that improves heating efficiency by minimizing the generation of condensed water while steam is introduced and transfers appropriate moisture to a patient.

In general, anesthesia used to control pain during surgical operations or medical procedures includes local anesthesia in which anesthetic is administered directly to the surgical site, and peripheral anesthesia in the main nerve or spinal cord region to block pain in a wider area of the body. There are local anesthesia, such as regional anesthesia, in which an anesthetic is injected into the body, and general anesthesia, which anesthetizes the body and brain.

These anesthetics are divided into drug anesthetics using drugs and gas anesthetics in the form of gas. Gas anesthetics, which can control the degree of anesthesia while continuously measuring respiration and pulse in extreme situations such as surgery, are mainly used.

Since the patient cannot breathe on their own during general anesthesia, the respiratory circulation tube used in a general anesthetic machine using gas anesthetic supplies oxygen gas for artificial respiration along with an anesthetic to the lungs of the patient, and carbon dioxide generated after breathing. A continuous breathing cycle is achieved by exhaling the gas and residual anesthetic.

The above-described respiratory circulation tube includes an intake tube for injecting an anesthetic agent and oxygen gas for artificial respiration into the patient so that the patient breathes in, and branching from the intake tube to exhale carbon dioxide that is exhaled after the patient breathes An exhalation tube for doing this, branched to be connected to the outlet of the inhalation tube and the inlet of the expiratory tube, respectively, and a branch connector for circulating the anesthetic for artificial respiration with the anesthetic by biting the central protruding tube into the patient's mouth. It is configured, the inhalation tube is connected to an artificial respiration device that provides an anesthetic and oxygen gas for artificial respiration, and the exhalation tube is connected to a monitoring device for monitoring and monitoring the patient's breathing status at all times, such as an electrocardiogram. .

However, at this time, the anesthetic supplied to the patient is supplied by evaporating a volatile inhalational anesthetic liquid into a gaseous state through a vaporizer, and oxygen is also supplied in a gaseous state. At this time, the anesthetic gas and oxygen gas inhaled by the patient Since it is cold enough to give coldness to the patient, there is a problem in that it can cause the patient's body to deteriorate during surgery.

Therefore, in order to solve this problem, a technique of heating a cold anesthetic and oxygen gas by injecting heated water vapor into an intake tube has been developed and used.

However, the prior art breathing circulation tube heats the anesthetic agent and oxygen through which heated water vapor is introduced into the intake tube, and a difference between the temperature at the initial inlet position and the temperature supplied to the patient is generated, so that the temperature of the anesthetic agent and oxygen is There was a problem that it was difficult to maintain the set temperature.

In addition, in the prior art breathing circulation tube, internal condensate is generated due to the temperature difference generated when water vapor enters and reaches the position where the patient is supplied, and when the generated condensate remains in the intake tube, it contaminates the anesthetic agent and oxygen, and There was a problem that a failure occurred when reaching the measuring device connected through the .

And, the breathing circulation tube of the prior art requires a separate equipment for generating water vapor, and it is difficult to handle and expensive due to the need to supply while maintaining the temperature of the generated water vapor.
