Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical instruments, in particular to a portable dry-sealed drainage bottle. Background Art
[0002] Most existing drainage devices have a separated liquid storage bottle and a water seal bottle, and use a water seal to achieve safe drainage. The drainage fluid accumulates in the drainage bottle, and the outside air does not enter the human body. This drainage bottle using a water seal is large in size and complex in structure, and is prone to failure. In addition, multiple partition chambers need to be set inside the drainage bottle. It is inconvenient for patients to use this water seal bottle to exercise with a large range of motion. At this time, the water seal bottle is easy to tip over, causing the drainage fluid to flow back into the body, which is not conducive to the patient's rehabilitation exercise and physical recovery. Incomplete drainage forces early extubation; it is not easy to observe whether the patient is expelling gas normally after connecting the drainage bottle. Medical staff or the patient's family members need to look at the bubbles in the bottle cavity through the bottle wall to identify the patient's expulsion. Utility Model Content
[0003] The technical problem to be solved and the technical task proposed by the utility model are to provide a portable dry-sealed drainage bottle, the bottle cavity of the drainage bottle is small in size, there is only one bottle cavity without complicated partitions inside the bottle body, no water seal is required during use, there is no risk of the drainage bottle tipping over and the drainage fluid flowing back into the human body, the safety and convenience of drainage are improved, and the patient can carry the utility model with him for rehabilitation exercises and daily activities, which is beneficial for the patient to leave the bed early for rehabilitation exercises and shorten the hospitalization time. At the same time, the utility model is also provided with an exposed exhaust observation structure to easily distinguish whether the patient has exhausted gas.
[0004] The utility model adopts the following technical scheme: a portable dry-sealed drainage bottle, including a drainage bottle body and a drainage joint connected to the bottle cavity, characterized in that the drainage bottle body is a single bottle cavity, an exhaust channel connected to the bottle cavity is horizontally arranged at the side wall position on the upper part of the drainage bottle body, a sealing valve that can block flow and exhaust one-way outward is arranged in the exhaust channel, and an open liquid storage tank is arranged around the outer surface of the drainage bottle body at the opening of the outer end of the exhaust channel. The drainage bottle described in the utility model has a simple internal structure with only one bottle cavity, and does not need to add water sealing liquid during operation. It can store liquid and exhaust gas outward at the same time. Even if the patient's activities cause the drainage bottle to tip over, the drainage liquid will not flow out, which is conducive to the patient leaving the bed early for rehabilitation exercises. Further, the utility model can also easily observe whether the patient is exhausting gas, which is suitable for home rehabilitation and clinical simple pneumothorax, avoiding the risks caused by too many functions and complex structure. During operation, the drainage connector drains and exhausts the patient through the drainage tube, and the drained liquid flows into the bottle cavity for temporary storage. The gas can be discharged outward through the exhaust channel through the one-way exhaust sealing valve, and the sealing valve simultaneously prevents the drainage liquid from flowing out; a small amount of normal saline is injected into the liquid storage tank to observe whether there are bubbles to determine whether the patient is exhausting. The utility model is suitable for patients with general pneumothorax, no effusion or chest cavity that has not yet healed, and the drainage has not been thorough but has reached the conditions for transfer to another hospital or home rehabilitation, such as clinical simple pneumothorax.
