Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to infant patient special use takes rotatory safe carousel type closed phlegm pipe of inhaling.
Background
The sputum suction tube is used as a therapeutic tool, and is used for sucking out sputum in the trachea under the condition that the sputum is accumulated in the respiratory tract of a patient.
Mechanical ventilation is often used in critically ill or severely compromised patients and has a superior effect on maintaining respiratory function in such patients. However, mechanical ventilation requires insertion of a tracheal cannula or tracheotomy tube, and sputum produced in the lung of such patients will enter the tracheal cannula or tracheotomy tube through the trachea, causing respiratory blockage or contamination of the cannula. Therefore, the nursing staff needs to frequently and manually suck the sputum for the patients, because the manual sputum suction method is mostly adopted, an operator needs to supply oxygen at high concentration, prepare to suck the sputum tube, disconnect the breathing machine, and then suck the sputum in the gas tube, the process is more complicated and time-consuming, the sputum suction method is often completed by 2 persons under the conditions of mechanical ventilation and the like, the problems of treatment interruption of the breathing machine, cross infection, environmental pollution and the like are found by clinical use, the sputum suction under the condition not only brings pain to the patients, causes great waste of medical resources, but also increases the workload of the nursing staff.
The use of the closed sputum suction ensures the continuous mechanical ventilation of the patient; the closed sputum suction system relatively isolates the airway of a patient from the outside, and can prevent the patient and medical staff from being polluted when the closed sputum suction system is used for sucking sputum; the operator does not need to prepare to suck the sputum tube and disconnect the breathing machine every time, can be completed smoothly by only 1 person, is short in time, and improves the working efficiency of nursing staff. Therefore, the research on the enclosed sputum suction technical scheme in the trachea is significant.
The existing sputum suction tubes in the market are of two types, one type is a common open type sputum suction tube, one end (hereinafter referred to as a patient end) is opened to go deep into a respiratory tract, and the other end (hereinafter referred to as a machine end) is connected with a negative pressure source, but the open type sputum suction tube is easy to have the following problems when mechanical ventilation is used: the patient end is easy to contact with the inner wall of the respiratory tract, so that the port is blocked, and the aim of sucking phlegm cannot be fulfilled; airway pollution and environmental pollution; arrhythmia, hypoxemia; the pressure of an airway is greatly reduced, the lung is easy to descend, and the blood oxygen saturation is reduced; development of ventilator-associated pneumonia (VAP), and the like. The other type is a closed sputum suction tube, a water injection valve of the sputum suction tube in the market has no flow direction control, gas and liquid are easy to overflow, and the phenomena of microbial contamination and sealing failure caused by forgetting to close a liquid injection port cover in the operation process of an operator are easy to occur; some devices have no safety switch, and the washing liquid can flow back into the airway of the patient during washing; some have a simple and easy push-pull switch, open after this type of switch mistake is touched very easily to cause the risk of patient's oxygen deficiency, simultaneously, because of its structure reason, often can not effectual reaching seal the effect, the seepage of flush fluid can appear when washing, phlegm pipe is inhaled to this type of push-pull switch's closed when inserting patient's operation, can produce great vibrations because of pushing away, can bring very big uncomfortable sense to the patient. The patient end of the two types of sputum suction tubes in the current market is provided with a side opening, when the main hole is blocked by thick sputum in the sputum suction process, the side opening can easily cause the wall suction of the sputum suction tube due to the pressure generated by negative pressure sputum suction, so that the tracheal tract is damaged.
In addition, the existing closed sputum suction tubes in the market are provided with a large three-way or four-way joint, the joint consumes a part of tidal volume of a breathing machine, the influence on adults is small, the tidal volume of premature infants or large infants is small, dead space is increased due to the large joint, the breathing of a patient is influenced, and carbon dioxide retention of the patient can be caused due to the fact that exhaled carbon dioxide and inhaled oxygen are intersected at the large joint. At present, no closed sputum suction tube specially used for infant patients exists in the market.
