Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-knotting anesthesia breathing tube. Background Art

[0002] Breathing tubes can provide stable oxygen and airway pressure, and multiple treatment modes. They are frequently used in anesthesia and respiratory surgery.

[0003] Anesthesia and respiratory surgeries require the use of ventilators and anesthesia machines. The medical gases in the breathing circuits cannot reach the temperature and humidity required by the human body's internal respiratory tract, causing airway damage and increased sputum production, leading to airway obstruction. Furthermore, the breathing circuits cannot filter bacteria and viruses, causing lung infections. Furthermore, the breathing tubes often bend or kink during surgery, causing airway obstruction, seriously endangering the lives of doctors and patients, and reducing ventilation effectiveness.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an anti-knot anesthesia breathing tube. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tangle-resistant anesthesia breathing circuit to solve the problem of being unable to filter bacteria and viruses in the circuit, which can lead to lung infections in patients. Furthermore, breathing tubes often bend or tangle during surgery, causing airway obstruction, seriously endangering the lives of doctors and patients, and reducing ventilation effectiveness.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] An anti-knot anesthesia breathing tube comprises a heat and moisture exchange filter housing lower cover, wherein a heat and moisture exchanger housing upper cover is provided on one side of the heat and moisture exchange filter housing lower cover;

[0008] The heat and moisture exchange filter housing lower cover is provided with a heat and moisture exchange medium and a filter membrane, and one side of the heat and moisture exchange housing upper cover is provided with a breathing tube 1 and a breathing tube 2.

[0009] Preferably, the upper cover of the heat and moisture exchanger housing further includes two parallel inner conical joints that comply with the provisions of the YY. standard.

[0010] Preferably, the heat and moisture exchange medium is composed of polyurethane soft foam coated with calcium chloride.

[0011] Preferably, the heat and moisture exchange medium is composed of corrugated moistening paper.

[0012] Preferably, the filter membrane is composed of electret polypropylene staple fibers.

[0013] Preferably, the inner cavities of the breathing tube 1 and the breathing tube 2 are both equilateral triangular holes that are anti-knotting.

[0014] Preferably, the breathing tube 1 and the breathing tube 2 are installed side by side and bonded with plastic.

[0015] Preferably, a patient end interface is provided at one end of the lower cover of the heat and moisture exchange filter housing.

[0016] Preferably, one end of the breathing tube is provided with a machine end interface.

[0017] The above technical solution has the following beneficial effects:

[0018] When ventilating medical gases such as anesthetic gases, the device first passes through a breathing tube with regular triangular holes, filters bacteria and viruses through a filter membrane, and then exchanges heat and moisture through a heat and moisture exchange medium, achieving a gas temperature and humidity suitable for inhalation before ultimately reaching the patient's airway. This reduces dead space, avoids nosocomial infection of bacteria and viruses, and prevents bending and kinking of the breathing tube. It also simplifies the installation process and facilitates operation for doctors. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0024] See also Figure 1 As shown, the utility model is an anti-knot anesthesia breathing tube, comprising a heat and moisture exchange filter housing lower cover 1, and a heat and moisture exchanger housing upper cover 2 is provided on one side of the heat and moisture exchange filter housing lower cover 1;

[0025] The heat and moisture exchange filter housing lower cover 1 is provided with a heat and moisture exchange medium 3 and a filter membrane 4 inside, and the heat and moisture exchanger housing upper cover 2 is provided with a breathing tube 1 5 and a breathing tube 2 6 on one side.

[0026] In order to solve the problem of connecting the upper cover 2 of the heat and moisture exchanger housing with the outside, the upper cover 2 of the heat and moisture exchanger housing further includes two parallel inner conical joints that comply with the provisions of the YY1040.1 standard.

[0027] In order to solve the problem of heat and moisture exchange, the heat and moisture exchange medium 3 is composed of polyurethane soft foam coated with calcium chloride.

[0028] In order to solve the problem of heat and moisture exchange, the heat and moisture exchange medium 3 is composed of corrugated moist paper.

[0029] In order to solve the problem of heat and moisture exchange, the filter membrane 4 is composed of electret polypropylene short fibers.

[0030] In order to solve the problem of heat and moisture exchange, the inner cavities of the breathing tube 1 5 and the breathing tube 2 6 are both equilateral triangular holes that are anti-knotting.

[0031] In order to solve the problem of connecting the breathing tube 1 5 and the breathing tube 2 6 , the breathing tube 1 5 and the breathing tube 2 6 are installed side by side and bonded with plastic.

[0032] In order to solve the connection problem of the lower cover 1 of the heat and moisture exchange filter housing, a patient end interface 7 is provided at one end of the lower cover 1 of the heat and moisture exchange filter housing. The patient end interface 7 is an outer conical joint that complies with the YY1040.1 standard.

[0034] Working Principle: Connect the patient-side interface 7 on the HMEF housing lower cover 1 to the patient or anesthesia mask. The two connectors on the HMEF housing lower cover 1 connect to the outer conical connector of breathing tube 1 5, and the inner conical connector of breathing tube 1 5 connects to the anesthesia / ventilator. Medical gas delivered from the anesthesia / ventilator passes through breathing tube 1 5, the HMEF housing lower cover 1, the filter membrane 4, and the HMEF medium 3, before entering the patient's body. If gas monitoring is required, an auxiliary connector on the HMEF housing lower cover 1 can be opened to connect the gas monitoring line. During ventilation, anesthetic and other medical gases first pass through the breathing tube with a regular triangular hole, filter the membrane 4 for bacteria and viruses, and then pass through the HMEF medium 3 for heat and moisture exchange, achieving a suitable temperature and humidity for inhalation before finally reaching the patient's airway. This reduces dead space, prevents nosocomial bacterial and viral infections, and avoids kinking and kinking in the breathing tube. It also simplifies the installation process and facilitates operation for doctors.
