Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a sputum collecting device for a tracheotomy cannula opening. Background Art

[0002] Tracheotomy is widely used in laryngeal dyspnea, respiratory dysfunction or dyspnea caused by retention of lower respiratory tract secretions; after the operation, one end of the tracheotomy cannula needs to be inserted into the patient's airway, and the other end is used to connect to a ventilator to provide oxygen for the patient or to perform treatment and care such as humidification and atomization of the patient's airway. However, for some patients with autonomous breathing function who do not need to be connected to a ventilator for assisted ventilation but need to survive with a long-term indwelling tube, the following problems often occur clinically:

[0003] 1. The other end of the tracheotomy cannula is directly open to the outside, and bacteria and dust can directly enter the patient's airway, increasing the risk of infection; even foreign objects may fall into the patient's airway, endangering the patient's life. Generally, covering with a wet gauze is commonly used clinically, but the gauze also brings another problem. For patients with more sputum, it may cause unsmooth expectoration, and the sputum may flow back into the lungs, aggravating pulmonary infection;

[0004] 2. If not covered, for patients with a certain cough ability or more sputum, the sputum is also extremely easy to spray and splash upward and around, causing sputum to adhere around the trachea. This not only increases the difficulty of cleaning, but also increases the nursing work of repeatedly replacing the square gauze of the tracheal intubation. Moreover, the sputum repeatedly enters and exits the opening of the tracheotomy cannula, increasing the possibility of contamination, easily aggravating respiratory tract infection, making the infection difficult to control, further increasing the patient's pain and consuming more treatment costs;

[0005] 3. Ordinary tracheotomy cannulas do not have the function of collecting sputum, and the measurement of the amount and characteristics of sputum is not objective, accurate, which is not conducive to doctors observing and judging the condition and adjusting the use of antibiotics.

[0006] Therefore, a sputum collecting device for a tracheotomy cannula opening is proposed. Content of the Utility Model

[0007] Aiming at the deficiencies of the prior art, the utility model provides a sputum collecting device for a tracheotomy cannula opening, which solves the problems of single function of the tracheotomy cannula and inconvenient use when a patient who does not need to be connected to a ventilator for assisted ventilation but needs to survive with a long-term indwelling tube wears the tube.

[0008] The present utility model also provides a sputum collection device for a tracheotomy cannula orifice, which includes a mounting plate. Elastic bandages are fixedly connected to both ends of the mounting plate. A tracheal connecting pipe is fixedly connected to the mounting plate. A pipeline is installed at the outer end of the tracheal connecting pipe. The pipeline is L-shaped, and breathing devices are installed on both the horizontal section and the vertical section. A one-way valve is fixedly connected to the inner wall at the lower end of the pipeline, and a collection device is threadedly connected to the outer wall. The collection device includes a disc. A connecting ring is fixedly connected to the upper side of the disc, and a collection bag is fixedly connected to the lower side. A scale bar is provided on the collection bag.

[0009] According to the sputum collection device for a tracheotomy cannula orifice, the breathing device includes a protective cover and a base. The lower end of the base is fixedly connected to the pipeline, and the upper end is threadedly connected to the protective cover.

[0010] According to the sputum collection device for a tracheotomy cannula orifice, an inhalation check valve is installed in the base on the vertical section of the pipeline, and an exhalation check valve is installed in the base on the horizontal section of the pipeline.

[0011] According to the sputum collection device for a tracheotomy cannula orifice, the surface of the protective cover is provided with ventilation holes, and an annular groove is provided on the inner side wall. A filter cotton is installed in the annular groove.

[0012] According to the sputum collection device for a tracheotomy cannula orifice, there are several ventilation holes, and they are evenly distributed.

[0013] According to the sputum collection device for a tracheotomy cannula orifice, the rear end of the tracheal connecting pipe is connected to a tracheal cannula.

[0014] The present utility model has the following beneficial effects:

[0015] 1. In the present utility model, by connecting an L-shaped pipeline and a collection bag to the outer end of the tracheal cannula, it is small in volume, simple in structure, and convenient to carry. At the same time, a scale bar is provided on the collection bag, which is convenient for observing the amount of sputum.

[0016] 2. In the present utility model, by installing a breathing device on the pipeline, when exhaling, the exhaled gas is exhaled from the breathing device with an inhalation check valve. When inhaling, the gas is inhaled from the breathing device with an exhalation check valve. At the same time, under the action of the filter cotton, the inhaled gas is filtered to avoid causing secondary infection of the respiratory tract, and the safety is good.

[0017] The additional aspects and advantages of the present utility model will be partially given in the following description, partially will become obvious from the following description, or will be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS
