Description

Portable one-way valve closed thoracic drainage device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a portable one-way valve closed thoracic drainage device.

Background

At present, a water-sealed bottle is generally adopted in the chest and heart surgery as an exhaust part of a closed thoracic drainage device (namely, physiological saline is used for isolating air and evacuating pneumatosis or/and hydrops in the thoracic cavity in a one-way mode). The novel medical water-sealed bottle is large in size and heavy in weight, needs to be fixed on the chest wall of a patient in a sewing mode, can leave scars, and can draw the sewing position to cause pain and discomfort of the patient due to the fact that the water-sealed bottle which is heavy to 1 jin + can also draw the sewing position. In addition, the closed drainage device for exhausting the water-sealed bottle greatly limits the movement of the patient, is not convenient for the patient to get out of bed for movement and walk after the operation, and influences the lung re-expansion process of the patient. And due to the weight, the tube is in danger of being pulled out, namely, the patient can tear the suture part of the chest wall by over-pulling when not paying attention to the tube, and further the adverse events such as unplanned tube drawing and the like of the pull-out of the chest tube are caused.

In addition, the patients who use the water-sealed bottle to carry out thoracic closed drainage can only carry out hospitalization, wherein one type of the patients is the patients who are partially youngsters and young people who have spontaneous pneumothorax and refuse surgical treatment, and the patients mostly have no special treatment. But delays the work and study of patients, and the hospitalization time of the patients is usually 3-5 days. The other is a patient with poor lung quality or lung function before operation, the delayed and unhealed lung surface laceration can occur after operation, the patient needs to be hospitalized for a long time with a tube to wait for the natural healing of the laceration, no special treatment is needed, and the hospitalization time of the patient is calculated by taking a month as a unit. The portable one-way valve closed drainage device for the thoracic cavity is provided for solving the problems that the thoracic cavity needs to be sealed by a water sealing bottle device and other treatment is not needed, namely the patient needs to be sealed by the water sealing bottle device, the patient can not be maintained in a hospital by himself due to the safety, the attractiveness and the portability, medical resources are wasted while inconvenience is caused to treatment, life and study of the patient, the hospitalization cost is increased, the unplanned tube drawing risk is increased, and the portable one-way valve closed drainage device for the thoracic cavity is inconvenient to maintain and replace.

Among the above-mentioned devices, pigtail 1 has now been widely used in thorax closed drainage, and other devices all select medical material, and do not get into the human body, and the security is high.

The using method and the steps are that whether the patient has pneumothorax (1, symptoms, namely cough, weight increase, severe exercise and other inducements frequently existing in the patient, typical symptoms are sudden onset of disease, severe chest pain at the affected side, then dyspnea and irritative dry cough occur, the onset of disease is slow in a small number of patients, no obvious symptoms exist, dyspnea is obvious in tension pneumothorax patients, severe cyanosis patients can have shock and coma 2, signs, namely, the signs are not obvious in small pneumothorax, the pneumothorax is more than 30 percent, the patient has a full chest contour, the intercostal space is widened, respiratory exercise is weakened, percussion is drumbeating, heart and liver voiced regions disappear, and trembling and respiratory sound are weakened or disappear in small pneumothorax at the left side, the snapping sound synchronous with the heart at the left edge can be heard, hamman is called, the patient inhales at the left side most clearly, the large pneumothorax can shift the heart and trachea to the healthy side, and water can be smelled in the hydropneumothorax 3, And (3) x-ray inspection: the transparency of the affected part of the pneumothorax is increased, and no pulmonary striation exists; the lung collapses towards the hilum and leaves when the lung is not shrinking. Sometimes, a streak or band-like adhesion on the pleural surface is seen, and a lung compression is clearly seen with a lung ct). After the diagnosis is definite, the improved closed thoracic drainage (puncture indwelling pigtail) on the affected side can be performed, and the second intercostal space on the midline of the clavicle is often selected as the puncture point. After the pipe is successfully placed, the first connecting sleeve 2 is connected to assemble the three-way pipe 4, and then the third connecting sleeve 11 is connected to assemble the one-way valve drainage device. If the patient does not incorporate the pleural fluid, the rotary switch 14 is closed, otherwise the second connecting sleeve 7 is connected with the fluid drainage device and the rotary switch 14 is opened. Finally, the three-way pipe 4 and the shell 17 are respectively fixed on the chest wall through transparent application. The drainage bag 9 is fixed inside the clothes of the patient by a pin. The patient coughs and observes the amplitude and the activity time of the integrated rubber valve 13. If the amplitude is large and the duration is long, the patient still has air leakage. If the integral rubber valve 13 does not move obviously when the patient coughs, the adjusting button 15 can be closed to clamp the second bent pipe 12, if the symptoms such as chest tightness, dyspnea and the like do not exist within 24 hours after the pipe is clamped, the pigtail 1 can be pulled out after the chest film is rechecked and no obvious pneumothorax symptom is found.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
