Description

Drainage bottle with dual purposes of dry sealing and water sealing

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a dry-sealing and water-sealing dual-purpose drainage bottle.

Background

Most of the existing commonly used drainage bottles need to be pre-filled with water sealing liquid for sealing, so that the safe exhaust of the thoracic cavity is ensured during continuous drainage, and the pneumothorax is prevented from being caused by the direct communication of the external air through the thoracic cavity of a patient. When the drainage bottle with the water seal liquid is inclined to one side or completely topples over in use, most of the water seal liquid flows to one side to cause water seal failure, so that the outside air is directly communicated with the thoracic cavity of a patient, the patient is uncomfortable if the outside air is light, and the pneumothorax danger is generated if the outside air is heavy.

SUMMERY OF THE UTILITY MODEL

The drainage bottle can select dry sealing drainage without using water sealing or water sealing drainage by switching a switch, can prevent external air from directly passing through the chest of a patient to cause discomfort or cause pneumothorax under the action of a dry sealing valve even if the bottle body inclines or completely topples under the condition of water sealing drainage, is convenient to drain and good in safety, is suitable for patients who leave a bed early and take exercise actively to help quick recovery, and can still keep all advantages of water sealing functions such as clear water column fluctuation and the like under the action of the water sealing in clinical use.

The utility model adopts the following technical scheme: a drainage bottle with dual purposes of dry sealing and water sealing comprises a sealed bottle body, wherein a communicating liquid accumulation cavity and a water sealing cavity are arranged in the bottle body, a drainage joint communicated with the liquid accumulation cavity and a negative pressure suction joint communicated with the water sealing cavity are arranged on the bottle body, and a sealed liquid feeding hole communicated with the water sealing cavity is arranged on the bottle body. The negative pressure suction connector is communicated with the upper-layer exhaust pipe section, the upper-layer exhaust pipe section and the lower-layer exhaust pipe section are communicated through the anti-overflow device, when the dry seal valve is opened, the lower-layer exhaust pipe section is unidirectionally discharged to the upper-layer exhaust pipe section through the anti-overflow device, the anti-overflow pipe is communicated with the lower-layer exhaust pipe section and the anti-overflow device and can prevent water seal liquid from flowing into the anti-overflow device, an exhaust hole passage communicated with the lower-layer exhaust pipe section is arranged on the bottle body, and an exhaust hole passage communicated with the lower-layer exhaust pipe section is provided with a switchable switch capable of opening/closing the hole passage. The drainage device can select dry sealing or water sealing drainage, and the pre-stored water sealing liquid can keep effective and reliable water sealing even if the bottle body inclines or completely topples over under the condition of water sealing drainage, so that discomfort or pneumothorax caused by external air directly reaching the thoracic cavity of a patient is prevented, and the drainage is convenient and safe. When the corresponding exhaust duct is opened by the change-over switch, the lower exhaust pipe section butted with the water seal cavity is directly communicated with the outside through the exhaust duct, at the moment, a proper amount of water seal liquid needs to be injected into the water seal cavity through the liquid adding hole in advance, the drainage bottle conducts water seal drainage, accumulated liquid drained from the thoracic cavity of the patient is stored in the accumulated liquid cavity, the accumulated gas is drained through the opened exhaust duct after sequentially passing through the communicating pipe, the buffer cavity and the water seal cavity, at the moment, water column fluctuation is clear, and the water seal advantage is obvious; when the corresponding exhaust duct is closed by the change-over switch, a small amount of liquid is required to be injected at the moment and is only displayed as water column fluctuation and not used as water seal liquid, the drainage bottle is used for dry seal drainage, the drained accumulated liquid is still stored in the accumulated liquid cavity, the accumulated gas sequentially passes through the communicating pipe, the buffer cavity, the water seal cavity, the lower exhaust duct section and the anti-overflow device and then enters the upper exhaust duct section, and then is discharged from the negative pressure suction connection suction head to the central negative pressure suction; the buffer cavity, the flow stop valve and the communicating pipe are used for preventing water seal liquid from flowing back into the accumulated liquid cavity to lose the water seal effect under the condition that a drainage bottle topples during water seal drainage, because two ends of the communicating pipe respectively extend into the upper parts of the buffer cavity and the accumulated liquid cavity, under the condition that the bottle body inclines or even completely topples, the water seal liquid slowly flows into the buffer cavity through the flow stop valve, and only can flow into the accumulated liquid cavity from the pipe orifice at the other end of the communicating pipe after the liquid level exceeds the pipe orifice at one end of the communicating pipe and penetrates through the communicating pipe, a small amount of water seal liquid is stored even if the liquid level of the water seal liquid flows into the buffer cavity and is far lower than the port of the communicating pipe at one side, once the bottle body is righted, the small amount of water seal liquid can be quickly replenished into a water column fluctuation pipe section through the flow stop valve, and therefore the water seal liquid cannot flow back into the accumulated liquid cavity to cause water seal failure; the dry sealing valve in the anti-overflow buffer device can realize that accumulated air of drainage is exhausted to one side of the upper exhaust pipe section in a one-way mode, outside air cannot reversely enter the anti-overflow buffer device through the dry sealing valve, the anti-overflow pipe is used for preventing water sealing liquid from flowing into the anti-overflow buffer device under the condition that the drainage bottle is toppled over, and water sealing failure caused by water sealing liquid loss is avoided. In addition, the exposed open ends of the suction connector and the drainage connector can be additionally provided with dustproof plugs for covering and protecting, the two connectors are separated from the outside, and the dustproof plugs are removed to be connected with the central negative pressure suction pipe or the drainage pipe when the corresponding connectors are needed.
