Description

Technical Field

[0001] The utility model belongs to the technical field of thoracic water seal drainage bottles, and in particular relates to a thoracic water seal drainage bottle. Background Art

[0002] A thoracic water seal drainage bottle is suitable for patients with pneumothorax, pleural effusion caused by various reasons and those who need closed drainage after surgery. Common types include single-chamber, double-chamber and triple-chamber. Currently in domestic hospitals, three-chamber thoracic water seal drainage bottles are more common. A three-chamber thoracic water seal drainage bottle usually consists of an effusion chamber, a water seal chamber and a suction control chamber, including a drainage pipe, an anti-backflow valve, a connecting pipe, a water seal, an exhaust and suction interface, an automatic positive pressure release valve, a water column fluctuation observation unit, a pressure regulating channel and a base.

[0003] In the prior art, only one drainage tube interface is provided for the chest drainage bottle, which can be connected to one drainage tube for drainage. However, after open lung surgery, two drainage tubes need to be used simultaneously to drain the upper and lower parts of the chest cavity respectively. After heart surgery, two drainage tubes are also needed to drain the pericardium and mediastinum respectively. In this case, in order to ensure the drainage efficiency, two drainage bottles need to be used simultaneously to connect the two drainage tubes respectively, resulting in a higher cost for using the drainage bottles. In addition, it may be necessary to collect the patient's pleural fluid during drainage. Usually, the pleural fluid is collected from the drainage tube interface, which requires the drainage tube to be separated from the interface. After separation, droplets from the drainage tube are likely to drip and contaminate the outside and the table of the drainage bottle, and the operation is also inconvenient. Therefore, a chest water seal drainage bottle is proposed, which can insert two drainage tubes at the same time and is convenient for sampling. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] See also Figure 1 , Figure 2 and Figure 3 As shown, a thoracic water seal drainage bottle comprises:

[0032] The liquid accumulation chamber 1, the water seal chamber 2 and the suction control chamber 3 are all fixedly mounted on the upper surface of the base 4, and the tops of the adjacent sides of the water seal chamber 2 and the suction control chamber 3 are connected;

[0033] Drainage ports 5, two drainage ports 5 are fixedly mounted on one side of the top of the effusion chamber 1, and are communicated with the interior of the effusion chamber 1;

[0034] A water column fluctuation observation unit 6, the lower end of which is connected to one side of the bottom of the water seal chamber 2, and the top of which is connected to the other side of the top of the liquid accumulation chamber 1 through an anti-backflow valve and a connecting pipe 7;

[0035] The water seal liquid adding and air suction and exhaust interface 8 is fixedly installed on the top of the water seal cavity 2 and communicated with the interior of the water seal cavity 2;

[0036] An automatic positive pressure release valve 9, which is fixedly mounted on the top of the suction control chamber 3, and whose lower end is communicated with the interior of the suction control chamber 3;

[0037] A pressure regulating channel 10, the lower end of which is communicated with one side of the bottom of the suction control chamber 3;

[0038] A sampling port 14, which is opened on a side of the liquid accumulation chamber 1 and has a rubber stopper 15 installed thereon;

[0039] The liquid accumulation chamber 1, the water seal chamber 2, the suction control chamber 3, the water column fluctuation observation unit 6 and the pressure regulating channel 10 are all made of transparent plastic material.

[0040] As can be seen from the above, by setting two drainage ports 5 at the top of the effusion cavity 1, not only can the number of drainage tubes connected to a single drainage bottle be increased, the number of drainage bottles used can be reduced during chest drainage, thereby reducing medical costs, but the unit flow rate of the liquid in the drainage tube can also be guaranteed. Compared with the design of installing a three-way connector on the drainage port 5, the flow rate of each drainage tube can be guaranteed to avoid the drainage speed being too low. By setting the sampling port 14 and the rubber stopper 15, when it is necessary to sample the drained liquid, the needle of the syringe can be directly used to pierce the rubber stopper 15 for sampling.

[0041] Specifically, by Figure 1 It can be seen that the upper ends of the drainage port 5, the anti-backflow valve and the connecting pipe 7, the water seal liquid filling and suction and exhaust interface 8, the automatic positive pressure release valve 9 and the pressure regulating channel 10 all extend to the same height.

[0042] As can be seen from the above, when using the drainage bottle, the liquid heights in each chamber can be relatively close, thereby avoiding the occurrence of liquid interruption and additional overflow.

[0043] Specifically, by Figure 3 It can be seen that the interior of the liquid accumulation chamber 1 is divided into three overflow chambers connected at the top by two half partitions 11.

[0044] As can be seen from the above, by providing the half partition 11 to separate the overflow chamber, the liquid entering the liquid accumulation chamber 1 can be filtered by sedimentation and overflow.

[0045] Specifically, by Figure 3 It can be known that the drainage ports 5 are all connected to the interior of the overflow chamber far away from the water column fluctuation observation unit 6 .

[0046] It can be seen from the above that the liquid entering the liquid accumulation chamber 1 from the drainage port 5 will enter from a position far away from the water column fluctuation observation unit 6, thereby ensuring the effect of overflow filtration.

[0047] Specifically, by Figure 1 It can be seen that hooks 12 are installed on the sides of the liquid accumulation chamber 1 and the pressure regulating channel 10.

[0048] As can be seen from the above, the hook 12 is provided to hang the drainage bottle for use.

[0049] Specifically, by Figure 2 It can be seen that support blocks 13 are rotatably mounted at the four corners of the lower surface of the base 4 .

[0050] As can be seen from the above, when the support block 13 is rotated to open, the drainage bottle can be placed more stably on the ground or the table.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
