Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, in particular to a one-way valve type chest drainage device. Background Art

[0002] In patients with pneumothorax, patients undergoing thoracoscopic surgery routinely use water seal bottles for drainage. The commonly used three-chamber water seal bottles are composed of three tanks. The first tank is used to store drainage fluid, the second tank allows one-way airflow by pouring liquid, and the third chamber is connected for negative pressure suction. The water seal bottle is large in size and needs to be infused with sterile solution. The placement of the water seal bottle has strict requirements and cannot be tilted excessively, which may cause the pneumothorax to worsen. When the patient is connected to the water seal bottle and can get out of bed and move around, the water seal bottle severely restricts the patient's movement. In this era that advocates rapid recovery and some thoracoscopic surgeries require getting out of bed and moving around immediately after surgery, the water seal bottle seems a bit slow.

[0034] like Figure 1-5As shown, a one-way valve chest drainage device includes a drainage tube 100, a drainage bottle 200 and a one-way drainage assembly. The drainage bottle 200 is only provided with a liquid storage cavity, and a liquid inlet tube 201 and an air outlet tube 202 are provided on the top of the drainage bottle 200. The drainage tube 100 is connected to the liquid inlet tube 201, and the drainage tube 100 is sleeved on the liquid inlet tube 201 by its own elastic force, thereby being fixed on the liquid inlet tube 201, and the one-way drainage assembly is connected to the air outlet tube 202.

[0035] A surrounding plate 204 is provided at the bottom of the drainage bottle 200, and the surrounding plate 204 is provided at the bottom of the air outlet pipe 202. A second through hole 2041 is provided on the side wall of the surrounding plate 204. With the setting of the surrounding plate 204, even when the drainage bottle 200 is completely tilted, the surrounding plate can block the liquid, and only a small part of the liquid will flow into the air outlet pipe 202 from the second through hole, which effectively prevents liquid leakage and ensures normal gas circulation.

[0036] A drainage tube 205 is provided at the bottom of the drainage bottle 200 . A sealing plug is provided inside the drainage tube 205 . The drainage tube 205 is used to discharge the accumulated fluid in the drainage bottle 200 .

[0037] The one-way drainage component includes a first tube body 301, a second tube body 302, a one-way valve and a filter 303. The one-way valve is arranged in the first tube body 301, the filter 303 is arranged in the second tube body 302, and a connecting groove corresponding to the second tube body 302 is arranged on the side wall of the first tube body 301.

[0038] A support ring 304 is provided in the second tube body 302 . When the second tube body 302 is connected to the first tube body 301 , the filter screen 303 is clamped between the support ring 304 and the first tube body 301 , so that the filter screen 303 can be easily assembled and disassembled.

[0039] The one-way valve includes an upper cover 305, a lower cover 306, a partition 307 and a film 308, wherein the partition 307 and the film 308 are located between the upper cover 305 and the lower cover 306, the upper cover 305 is provided with an air inlet 3051, the lower cover 306 is provided with an air outlet 3061, the partition 307 is provided with a plurality of first through holes, the partition 307 is also provided with a second protrusion 3071, the second protrusion 3071 is provided with a limit plate 3072, and the cross section of the limit plate 3072 is larger than the cross section of the second protrusion 3071; the film 308 is provided with a third through hole The third through hole is sleeved on the second protrusion 3071, and the setting of the limiting plate 3072 prevents the film from detaching from the second protrusion; a pressure ring 309 is provided in the lower cover 306, the film 308 is made of silicone, and the pressure ring 309 is made of PE; the setting of the pressure ring 309 allows the film 308 to be more effectively attached to the partition 307, thereby playing the role of closing the one-way valve; the one-way valve is closed when the patient inhales and opens when the patient exhales, effectively discharging the gas entering the drainage bottle 200 and preventing the gas from flowing back.

[0040] A drying element 310 is provided in the first tube body 301, and the drying element 310 is provided on one side of the one-way valve; the drying element 310 is an annular drying paper; a convex ring 311 and a first convex block 312 are provided on the inner wall of the first tube body 301, and the drying element 310 is located between the convex ring 311 and the first convex block 312; the drying element 310 is used to absorb the liquid entering into the first tube body 301, and even if a small amount of liquid enters into the first tube body when the drainage bottle is tipped over, the drying element 310 can be used to absorb the liquid entering into the first tube body 301, thereby avoiding liquid leakage.

[0041] When indoors, the drainage bag can be placed beside the bed, and the drainage tube 100 can be directly connected to the drainage bag for use. By observing the expansion of the drainage bag, medical staff can observe the patient's recovery status.

[0042] The drainage tube 100 can also be connected to a conventional three-chamber water seal bottle for use, or directly connected to a one-way drainage component for use when the patient has no fluid accumulation.

[0043] When in use, the drainage tube 100 can be connected to a soft tube at one end to meet the patient's daily activity needs and enhance the patient's comfort.

[0044] The size of the drainage bottle 200 is preferably 5cm*2cm*8cm, which is far from the ideal size and weight, and meets the current needs of rapid recovery and early getting out of bed.
