Embodiment 1

[0022] Embodiment 1 provides an exhaled breath condensate collector, the structure of which will be described in detail below.

[0023] refer to figure 1 The exhaled gas condensate collector includes a refrigeration system and a condensate collection system. The refrigeration system includes a temperature control box 1 and a condensation tube sleeve 2. The temperature control box 1 and the condensation tube sleeve 2 are connected by a flexible pipe 3.

[0024] refer to figure 2 , the refrigeration system also includes a circulation conduit 11, a compressor 12, a condenser 13, a capillary tube 14, and an evaporator 15, wherein the compressor 12, the condenser 13, and the capillary tube 14 are all arranged in the temperature control box 1, and the evaporator 15 is a spiral tube Type evaporator, the evaporator 15 is wound on the outer wall of the condenser tube sleeve 2. The minimum temperature of the evaporator 15 is controllable at -45 degrees, and the commonly used temperat...

Abstract

The invention discloses an exhaled breath condensate collector. The collector comprises a refrigeration system and a condensate collecting system; the refrigeration system comprises a temperature control box and a condensation tube sleeve, and the outer wall of the condensation tube sleeve is provided with an evaporator; the condensate collecting system comprises a breath inlet nozzle, an inhalation and exhalation four-way control valve, a condensation tube and a collecting cup, the inhalation and exhalation four-way control valve comprises a breath inlet nozzle connector, an inhalation inlet,an exhalation outlet and a condensation tube connector, and the collecting cup sleeves the bottom of an outer tube of a condensation tube; during use, the condensation tube sleeve sleeves the outer wall of the condensation tube and the collecting cup. The exhaled breath condensate collector is convenient to mount and dismount, the refrigeration system and the condensate collecting system are structurally independent, a patient is subjected to exhaled breath condensate detection without sitting up, and the collector is friendly to users.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an exhaled breath condensate collector. Background technique [0002] Respiratory system disease is one of common and frequently-occurring diseases. According to statistics, respiratory system disease ranks first in the cause of death of the total population in my country among the causes of mortality in cities. Asthma, chronic obstructive pulmonary disease (COPD for short), acute respiratory distress syndrome (ARDS for short) and interstitial lung disease are all common respiratory diseases. Oxidative stress in the airways, airway inflammation leading to airway inflammation and the main cause of these respiratory diseases. [0003] Exhaled breath condensate (EBC) detection, as a completely non-invasive detection technology of respiratory inflammation status, has attracted much attention in recent years. The exhaled gas contains not only volatile substances such as NO, ...
