Abstract

The utility model relates to a medical device, particularly a sealed type negative pressure sucking water sealing bottle for the drainage of thoracic and abdominal cavities. The utility model comprises a liquid loading bottle, a water sealing pressure adjusting bottle, a bottle cap of the water sealing pressure adjusting bottle, a drainage tube and a communicating tube. The bottle cap of the liquid loading bottle is provided with a drainage connecting column and a communication connecting column, and the water sealing pressure adjusting bottle cap is provided with a connecting column of a water sealing tube, a liquid feeding connecting column and a pressure regulating connecting column. The water sealing tube and the adjusting tube on the lower ends of the connecting columns need to be inserted in the bottle bottom and are sealed by water. The pressure adjusting connecting column is connected with a negative pressure ball. The negative pressure ball can adjust the negative pressure value in a negative pressure chamber without the limitation of regional conditions. The utility model overcomes the defects of oversize volume and complicated manufacture of the water sealing bottle with three chambers existing in the prior art, and un-adjustable negative pressure value when a patient uses the water sealing bottle during shifting. The utility model is particularly suitable for primary hospitals.

Description

Practical enclosed vacuum suction water-sealed drainage bottle

This utility model relates to a kind of medical apparatus and instruments, the vacuum suction water-sealed drainage bottle that the patient that particularly being applicable to needs closed drainage behind spontaneous pneumothorax, traumatic pneumothorax, hemothorax, empyema, tumor and the thoracic surgery is used.

The present vacuum suction water-sealed drainage bottle that uses, mostly being greatly of adopting comprises that diversion chamber, negative pressure chamber, negative pressure adjust the structure that three Room, chamber are formed, as the disposable closed thoracic vacuum suction water-sealed drainage bottle of Chinese patent CN2102752 bulletin, it is adjusted the chamber, is had negative pressure chamber and the bottle cap of adjusting pipe and formed by splanchnocoel drainage tube, flow liquid amount container, vacuum suction pipe, filling opening, suction pump adapter, negative pressure chamber, negative pressure.The weak point of this water-sealed drainage bottle is: 1, to take volume excessive in three Room, makes complicated; 2, take over when being connected on the outer suction pump when suction pump, the mobility of water-sealed drainage bottle is just poor, during particularly patient performs the operation afterwards transfer process, just can not connect outer suction pump; 3, in the place that does not have outer suction pump, particularly in basic hospital or patients home, use, the drainage effect of water-sealed drainage bottle is relatively poor.

Task of the present utility model is the deficiency at the said goods, a kind of need two Room is provided, is convenient to observe the drain result, has the negative pressure regulatory function, is convenient to move the middle practical enclosed vacuum suction water-sealed drainage bottle that uses.

Two Room of the present utility model are by the hydrops bottle, water seal adjust blood pressure bottle is formed, fixing several posts that connect on two bottles the bottle cap respectively, be to have a drain to connect post on the hydrops bottle cap and connection connects post, drain connects the post upper end and is connected with the drainage tube that inserts splanchnocoel, there is water sealing (sealing water) pipe to connect post on the water seal adjust blood pressure bottle cap, liquid feeding connects post and adjust blood pressure connects post, water sealing (sealing water) pipe connects post upper end and connects pole interconnection with being communicated with on a connecting pipe and the hydrops bottle cap, at the bottom of water sealing (sealing water) pipe connects the post lower end and has a water sealing (sealing water) pipe to be inserted into bottle, it is a funnel that liquid feeding connects the post upper end, adjustable pipe at the bottom of the lower end is connected to and is inserted into bottle, adjust blood pressure connects negative pressure ball of termination on the post.

Compare with existing product, this utility model has quantitatively reduced than original product at bottle, on function except that the function that has kept existing product, the place that also is specially adapted to need the patient who moves and does not have outer suction pump, strengthen the practicality of vacuum suction water-sealed drainage bottle, and be not subjected to the restriction of regional condition.

Fig. 1 is this utility model structural representation;

Fig. 2 is a kind of example structure cutaway view of check valve in the negative pressure ball;

Fig. 3 is the vertical view of Fig. 2.

Be described further below in conjunction with accompanying drawing: operation principle of the present utility model is to utilize the pressure differential between vacuum suction water-sealed drainage bottle and the human body splanchnocoel to carry out drain.As shown in Figure 1, the bottle of this device is connected as a single entity with polyethylene or the disposable moulded section of pvc material, hydrops bottle 1 and water seal adjust blood pressure bottle 16.In the hydrops bottle 1 available dividing plate be divided into three every, a bottle wall is marked with scale, is convenient to observe the drain result, and can measure correctly, distinguish that drawing liquid color attitude changes; Water seal adjust blood pressure bottle 16 need fill the normal saline of certain altitude when using, the top of bottle can form negative pressure chamber.Fixing drain on the bottle cap that hydrops bottle 1 and water seal adjust blood pressure bottle are 16 two bottles respectively connects post 2, is communicated with and connects that post 4, water sealing (sealing water) pipe connect post 6, liquid feeding connects post 8 and adjust blood pressure connects post 10, drain connects and connects drainage tube 3 on the post 2, the intravital hydrops of people is introduced hydrops bottle 1, connection connects post 4 and water sealing (sealing water) pipe connects the communicating pipe 5 that an interconnection is arranged between the post 6, negative pressure channel in linking up two bottles, water sealing (sealing water) pipe connect post 6 lower ends to be had at the bottom of a water sealing (sealing water) pipe 14 straight cutting bottles; It is that a funnel 9 is straight-through with atmosphere that liquid feeding connects post 8 upper ends, the lower end patches the adjustable pipe 15 at the bottom of the bottle, when the water seal liquid level was certain in the water seal adjust blood pressure bottle 16, the negative pressure space in the negative pressure chamber was also certain, kept stable negative pressure value when therefore the adjustable pipe 15 that communicates with atmosphere can make water-sealed drainage bottle work; Adjust blood pressure connects post 10 lower ends and communicates with negative pressure chamber, its upper end is connected with a negative pressure ball 12, this negative pressure ball is the air bag that respectively there is a check valve at two ends, two check valves 11,13 are settled in the same way, guarantee gas only export but no import in the adjust blood pressure bottle 16 during work, the negative pressure value in the negative pressure chamber is increased, when negative pressure ball 12 is not subjected to the external force extruding, check valve in the negative pressure ball is inoperative, and the vacuum suction water-sealed drainage bottle is nature constant drainage state.When patient's state of an illness more surely, need not move and have under the situation of electric suction apparatus, suction pump outside can connecting at the end of negative pressure ball, negative pressure ball then becomes a passage.

In order to prevent that liquid pours in down a chimney to the hydrops bottle in the water seal adjust blood pressure bottle, can be in two bottles of connecting pipelines check valve 7 of adjunction.
