Description

Disposable gas-liquid dual-purpose one-way closed drainage bag

Technical Field

The utility model belongs to the technical field of medical consumptive material, in particular to disposable gas-liquid dual-purpose one-way closed drainage bag.

Background

Closed thoracic drainage is a therapeutic means that one end of a drainage tube is placed in a thoracic cavity, the other end of the drainage tube is connected into a drainage bottle which is lower than the drainage tube, and the drainage bottle discharges gas or collects liquid in the thoracic cavity by taking gravity drainage as a principle, so that lung tissues are expanded again to restore functions. The purpose is to better improve the negative pressure of the pleural cavity, discharge the air, blood and liquid from the pleural cavity, prevent the reflux of the air, promote the re-expansion of the lung and close the pleural cavity; balancing pressure, preventing mediastinal shift and pulmonary compression.

The drainage bottle is a water-sealed bottle which is a wide-mouth glass bottle, and the drainage quantity is observed and recorded at any time according to the scales (marks) outside the drainage bottle; the bottle mouth is sealed by a rubber bottle plug, a drainage tube and an exhaust tube penetrate through the bottle plug, generally speaking, the drainage tube is far longer than the exhaust tube, the drainage bottle is 50-60cm lower than a pleural cavity, sterile saline or cold boiled water is placed in the bottle, and the bottle is marked after the water is placed in the bottle. One end of the drainage tube is connected with the thoracic cavity, and the other end is 1-2cm below the horizontal plane of the drainage bottle. The working principle is that the sum of the thoracic cavity pressure and the water column height pressure is equal to the atmospheric pressure. When the pressure in the chest cavity is higher than the atmospheric pressure, the gas in the chest cavity can overflow from the water-sealed bottle. When the pressure in the thoracic cavity is lower than the atmospheric pressure, the water column in the drainage tube rises, and when the pressure in the thoracic cavity plus the pressure generated by the rising water column of the drainage tube is equal to the atmospheric pressure, the balance is achieved, so that air cannot enter the thoracic cavity.

In the prior art, the drainage bottle has a single bottle, double bottle or triple bottle structure, as shown in fig. 1, 2 and 3.

Referring to fig. 1, in the single bottle structure, the pleural fluid is drained by placing the water-sealed bottle 101 below the thoracic cavity (e.g., when the patient is in a semi-recumbent position, the water-sealed bottle 101 is placed on the ground). Therefore, when only the hydrothorax is drained, a single bottle can be used, and only one drainage bag is usually used clinically. However, in the single bottle structure, as the liquid level rises due to the accumulation of the drainage liquid in the bottle, accordingly, the depth of the drainage tube 11 in the water becomes deeper, and it becomes difficult to leak gas and to prevent the lung from expanding, so that the operation is very troublesome and troublesome to adjust the insertion depth of the drainage tube 11 or to remove the liquid in the bottle at any time, and thus, it is rarely used.

Referring to fig. 2, in the double bottle structure, two bottles are connected in series through a connecting pipe, the first bottle is a collecting bottle 102, a drainage tube 11 connected to the thoracic cavity is provided on the stopper thereof, the second bottle is a water-sealed bottle 101 in which water is provided, one end of a first connecting pipe 104 in the water-sealed bottle 101 is located below the horizontal plane, and an exhaust pipe 4 is provided on the stopper of the water-sealed bottle 101. The double-bottle structure can drain pleural fluid and gas, the gas comes out from the thoracic cavity, the thoracic cavity liquid and gas pass through the collecting bottle 102 → the collecting liquid → the water seal bottle 101 → the gas comes out of the water surface from the water → the atmosphere, and the double-bottle structure is commonly used clinically. Therefore, even if the amount of drainage liquid is large, the drainage liquid only stays in the collection bottle 102, and the function of the water-sealed bottle 101 is not affected, so that the insertion depth of the first connection pipe 104 into the water-sealed bottle 101 does not need to be adjusted at any time. However, the two-bottle drainage device is not perfect, and when the patient still has no obvious re-expansion after 1 week of closed drainage, negative pressure continuous suction is needed. Negative pressure aspiration requires a "limited pressure" bottle, or problems can arise because the negative pressure is too great.

A three bottle configuration is proposed to overcome this problem and with reference to figure 3, it employs three bottles in series, in turn a collection bottle 102, a water-sealed bottle 101 and a pressure-limiting bottle 103. A drainage tube 11 connected with a thoracic cavity is arranged on a bottle stopper of a collecting bottle 102, water is arranged in a water-sealed bottle 101, a first connecting tube 104 is connected with the collecting bottle 102 and the water-sealed bottle 101, one end in the water-sealed bottle 101 is positioned below a horizontal plane, water is also arranged in a pressure limiting bottle 103 for limiting pressure, and the water depth can be 8-12cm; the second connecting pipe 105 connects the water-sealed bottle 101 and the pressure-limiting bottle 103, and one end of the water-sealed bottle 101 and one end of the pressure-limiting bottle 103 are both located above the horizontal plane, and a pressure adjusting pipe 106 and an exhaust pipe 4 are further arranged on the bottle plug of the pressure-limiting bottle 103, wherein the pressure adjusting pipe 106 is located below the horizontal plane, the exhaust pipe 4 is located above the horizontal plane, and the pressure adjusting pipe 106 can be connected with a negative pressure suction device (suction machine). When the negative pressure suction device is used, if the negative pressure suction is not needed, the pressure adjusting pipe 106 does not need to be connected with the negative pressure, and the atmospheric pressure can be directly connected. If negative pressure suction is required, the pressure regulating tube 106 is connected to a negative pressure suction device. Therefore, the three-bottle structure is that by adding 1 pressure-limiting bottle 103, when the broken pleura is still not healed after the pneumothorax is drained by the water-sealed bottle 101, the drainage of gas needs to be accelerated, and then the negative pressure suction device is used to apply an outward pulling force to the gas in the pleural cavity, so that the gas is more favorably discharged by pushing and pulling, and the healing of the broken pleura of the pneumothorax is favorably realized. However, the three-bottle structure has the disadvantages of being too complex, requiring a large amount of space for the three bottles, and wasting equipment especially when negative pressure suction is not required.

According to different scenes, the above-mentioned several kinds of structures of traditional thorax closed drainage bottle can be selected for use, however it all has following shortcoming:

1. large volume and inconvenient carrying and transportation.

2. The puncture point and each bottle body must keep gravity drainage and must keep a vertical distance of 50-60 cm.

3. Each drainage bottle can only be upright and cannot be inclined, and gas-liquid countercurrent can occur when the operation is improper.

4. It is inconvenient to use in wartime or emergency.

5. The drainage bottle and the liquid in the drainage bottle need to be replaced and disinfected every day.
