Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an integrated artificial airway warming and humidifying pipeline. Background Art

[0002] When a patient has difficulty breathing due to a tumor or foreign body blocking the pharynx or larynx, or respiratory dysfunction causing secretions to block the lower respiratory tract, the patient will suffer from hypoxia and a large amount of carbon dioxide will be retained in the blood, leading to the risk of suffocation and death. At this time, simply giving the patient oxygen cannot relieve the patient's hypoxia, but will make breathing more suppressed. Therefore, tracheotomy is needed to relieve the obstruction of the patient's respiratory tract, establish an artificial airway, and relieve breathing difficulties in order to achieve the purpose of auxiliary treatment.

[0003] Artificial airways are used clinically to simulate normal human breathing. Under normal circumstances, the gas exhaled by people will pass through the nasal cavity, pharyngeal cavity and respiratory tract in sequence, and finally flow into the human trachea after being heated and humidified by the nasal cavity and pharyngeal cavity. However, the artificial airway established through clinical surgery completely loses the heating and humidification function and requires the use of expensive high-flow oxygen therapy devices, which greatly increases the medical costs of patients.

[0004] In order to solve the problem of high cost of artificial airway, the prior art with publication number CN218529505U provides a method for humidifying and heating the gas exhaled into the artificial airway at a relatively low cost by using a heating humidifier to simulate the effects of the human nasal cavity, pharyngeal cavity and respiratory tract. Although this technical solution can reduce the cost of heating and humidifying the gas in the airway, since the breathing action of the human body causes the gas in the artificial airway to enter and exit, the gas exhaled by the human body is discharged through the third threaded pipe left in this technical solution, but since the pipe is directly connected to the outside world, the patient can also suck the gas directly exposed to the environment through the pipe. For patients in the ward, there are often multiple patients in the ward, and bacteria are easily bred in the air, so the gas directly sucked into the artificial airway through the pipe is not clean and is likely to cause other diseases. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an integrated artificial airway humidification pipeline, which utilizes the fact that when a patient inhales, a plastic ball will be adsorbed and move downward to block the exhaust port at the bottom of the plastic ball, thereby preventing the patient from directly inhaling the gas in the environment into the artificial airway, thereby helping to ensure the health of the patient.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an integrated artificial airway temperature and humidification pipeline, comprising an oxygen tube connected to the gas outlet end of the oxygen cylinder, the gas outlet end of the oxygen tube away from the oxygen cylinder is connected to a venturi tube for balancing the oxygen flow, and the side of the venturi tube away from the oxygen tube is provided with two heating tube assemblies for heating oxygen, one end of one heating tube assembly is connected to the gas outlet end of the venturi tube, a humidifying assembly for humidifying oxygen is provided between the two heating tube assemblies, the gas outlet end of the other heating tube assembly is connected to a trachea and an inhalation restriction assembly through a three-way pipe a, the trachea is connected to the artificial airway, and the inhalation restriction assembly is used to discharge the gas exhaled by the patient;

[0009] Preferably, a charging cable for energizing the electric heating wire is provided on the rear side of the thermal insulation sleeve, and the electric heating wire can be powered by inserting a plug at one end of the charging cable into a socket.

[0013] Compared with the prior art, the utility model provides an integrated artificial airway temperature and humidification pipeline, which has the following beneficial effects:

[0014] 1. The patient's exhaled gas is discharged by utilizing the provided curved pipe, and a lightweight plastic ball is provided at the top of the curved pipe, so that the patient's exhaled gas can blow the plastic ball upward, exposing the exhaust port at the bottom of the hollow column, thereby ensuring smooth exhaust.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, the utility model provides an integrated artificial airway temperature and humidification pipeline, including an oxygen tube 2 connected to the air outlet end of an oxygen cylinder 1, and oxygen is supplied to the patient by means of the oxygen released in the oxygen cylinder 1 to meet the patient's breathing needs; the air outlet end of the oxygen tube 2 away from the oxygen cylinder 1 is connected to a venturi tube 3 for balancing the oxygen flow, and the side of the venturi tube 3 away from the oxygen tube 2 is provided with two heating tube assemblies 4 for heating oxygen, one end of one heating tube assembly 4 is connected to the air outlet end of the venturi tube 3, and the air outlet end of the other heating tube assembly 4 is connected to a trachea 7 through a three-way pipe a6. When the utility model is in use, the trachea 7 is connected to the artificial airway;

[0029] Specifically, Figure 2 , 4 As shown in Figures 5 and 6, each heating tube assembly 4 includes a heat-insulating tube sleeve 41, a heat-conducting tube 42 is arranged inside the heat-insulating tube sleeve 41, an electric heating wire 43 for heating is wound around the outer end of the heat-conducting tube 42, the electric heating wire 43 is located between the heat-insulating tube sleeve 41 and the heat-conducting tube 42, the two heat-insulating tube sleeves 41 are connected by a three-way tube b45, and a charging line 44 for energizing the electric heating wire 43 is arranged on the rear side of the heat-insulating tube sleeve 41;

[0030] During use, the plug at one end of the charging cable 44 is inserted into the socket to supply power to the electric heating wire 43, so that the electric heating wire 43 can generate heat to heat the heat conducting tube 42, and then the heat conducting tube 42 can heat the oxygen flowing into the heat conducting tube 42 to prevent the temperature of the gas inhaled into the artificial airway from being too low and causing discomfort to the patient. In addition, the heat conducting tube 42 in the utility model is made of a heat conducting material and has good heat conducting properties. The heat insulating tube sleeve 41 is made of a heat insulating material and can isolate the heat emitted by the electric heating wire 43 to prevent scalding the patient.

[0031] In order to humidify the oxygen inside the heat-insulating tube sleeve 41, a humidifying assembly 5 for humidifying oxygen is provided between the two heating tube assemblies 4. Specifically, Figure 2As shown, the humidifying assembly 5 includes a humidifier water tank 51 containing distilled water, a humidifier head 52 powered by a built-in battery is threadedly connected to the top of the humidifier water tank 51, an air outlet pipe 53 is fixed to one side of the humidifier head 52, the top of the air outlet pipe 53 is connected to the interface at the bottom of the three-way pipe b45, and the air outlet pipe 53 is connected to the inside of the heat-insulating pipe sleeve 41 through the three-way pipe b45;

[0032] When the utility model is used, the oxygen cylinder 1 is opened to supply oxygen and the humidifier head 52 is started at the same time. The distilled water in the humidifier water tank 51 is absorbed by the humidifier head 52 to be atomized, and then the atomized water vapor is introduced into the insulation pipe sleeve 41 through the air outlet pipe 53 to increase the humidity of the oxygen, so as to achieve the effect of humidifying the oxygen, so that the utility model can simulate the effects of the nasal cavity, laryngeal cavity and respiratory tract during normal breathing of the patient, and can reduce the cost of heating and humidifying oxygen in the artificial airway. Moreover, the humidifier water tank 51, the humidifier head 52 and the insulation pipe sleeve 41 in the utility model are fixed together by the three-way pipe b45 to form an integrated arrangement, which can help reduce the volume of the utility model and make it convenient to use in ordinary wards.

[0033] The patient's breathing action not only requires the inhalation of oxygen, but also the exhalation of carbon dioxide, that is, exhaust. Therefore, in the present invention, the outlet end of another heating tube assembly 4 is connected to an inhalation restriction assembly 8 through a three-way pipe a6. The inhalation restriction assembly 8 can discharge the gas exhaled by the patient, and the inhalation restriction assembly 8 in the present invention can also prevent the patient from inhaling the gas in the ward, such as Figure 3 As shown, the air intake restriction assembly 8 includes a bend pipe 81 connected to an interface of the three-way pipe a6, a hollow column 82 is fixed to one end of the bend pipe 81 away from the three-way pipe a6, an exhaust port connected to the inside of the bend pipe 81 is opened at the bottom of the hollow column 82, and a plurality of air holes 83 connected to the outside are opened at the top of the bend pipe 81, and a plastic ball 84 is arranged at the bottom of the hollow column 82. The plastic ball 84 in the utility model is a hollow ball made of plastic and is light in weight;

[0034] When the patient exhales, the gas enters the hollow column 82 through the curved tube 81 and pushes the plastic ball 84 upward, exposing the exhaust port at the bottom of the hollow column 82. The exhaled gas is then discharged into the external environment through the air vent 83. Conversely, when the patient inhales, as the patient draws air, the bottom of the plastic ball 84 moves downward and blocks the exhaust port, preventing the patient from inhaling the germ-laden gas in the ward, thereby helping to ensure the patient's health.

[0035] Because the patient's breathing needs to continue, the distilled water in the humidifier water tank 51 needs to be replenished with new distilled water after it is used up. Figure 2As shown, a water supply pipe 54 for injecting water into the humidifier water tank 51 is connected to one side of the humidifier head 52, and a pipe cap 55 for sealing the pipe opening at the top of the water supply pipe 54 is threadedly connected to the top of the water supply pipe 54. When adding water, the pipe cap 55 needs to be removed from the top of the water supply pipe 54, and the pipe cap 55 needs to be re-covered on the top of the water supply pipe 54 after the water is added, so as to prevent bacteria in the ward from entering the humidifier water tank 51 through the water supply pipe 54 to cause contamination of the distilled water and threaten the health of the patient;

[0036] In addition, a type-c interface 56 is provided on one side of the humidifier head 52 where the water filling pipe 54 is installed. The type-c interface 56 is located at the bottom of the water filling pipe 54. The setting of the type-c interface 56 can facilitate medical staff to charge the humidifier head 52 using an ordinary mobile phone charging cable, thereby enhancing the convenience of the utility model.

The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
