Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a negative pressure suction device after pneumothorax surgery. Background Art

[0002] Pneumothorax occurs when air enters the pleural cavity, causing a buildup of air. This condition is often caused by lung disease or external forces, resulting in rupture of lung tissue and the visceral pleura, or the rupture of tiny emphysematous bubbles near the lung surface, allowing air from the lungs and bronchi to escape into the pleural cavity. The incidence of pneumothorax is high in patients undergoing surgery, as their immune system is weakened and they are not adapted to the external air pressure environment. Treatment of pneumothorax in postoperative patients is typically achieved with a continuous negative pressure drainage device with adjustable negative pressure.

[0003] The patent specification with the announcement number CN209253749U discloses a continuous negative pressure drainage device for neonatal pneumothorax, including a bottle body, wherein the bottle body contains a negative pressure drainage chamber, a negative pressure suction chamber, and a negative pressure regulating chamber, wherein the negative pressure drainage chamber, the negative pressure suction chamber, and the negative pressure regulating chamber are connected by a catheter, wherein the negative pressure drainage chamber is connected to a drainage tube, and wherein the negative pressure regulating chamber is connected to a negative pressure regulator and a negative pressure aspirator. The above-mentioned device reduces the overall volume of the negative pressure drainage device by combining the traditional negative pressure drainage bottle, negative pressure suction bottle, and negative pressure regulating bottle into one, and most of the catheters are set in the bottle body, and the few exposed ones are also sealed to ensure a sterile sealed environment in the bottle body. The structure is simple and easy to operate. In addition, the negative pressure in the negative pressure drainage chamber can be adjusted accordingly by observing the changes in the liquid level in the first catheter by comparing with the scale stripes.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when the above device is used with a negative pressure suction device, if the negative pressure generated by the suction machine is too large and there is no pressure regulating tube, then this excessive negative pressure will be directly transmitted to the chest cavity, which may cause damage to the lung tissue in extreme cases. In addition, when the patient coughs during negative pressure suction, water will spray out from the water addition hole, causing water to be all over the ground, affecting the surrounding environment. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a negative pressure suction device for post-pneumothorax surgery, which solves the problems in related technologies of being inconvenient to suction and discharge gas and liquid in the patient's chest cavity and preventing water from spraying out of the water supply hole when the patient coughs during negative pressure suction, resulting in water all over the ground.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] 1. The utility model opens the sealing cover and injects sterile water for injection or normal saline into the interior of the water seal bottle through the liquid inlet, then seals the sealing cover and the liquid inlet, and then injects sterile water for injection or normal saline into the interior of the pressure regulating bottle through the suction device interface. At this time, the suction device interface can be connected to the external negative pressure suction device, and then the drainage tube interface is connected to the drainage tube, and then the drainage tube is placed in the patient's chest cavity.

Because there is water inside the collection bottle, the water of the second water liquid will not splash significantly when entering the collection bottle, which solves the problem of preventing water from spraying out from the water adding hole when the patient coughs during negative pressure suction, resulting in water all over the ground.

[0023] Furthermore, a first bottle cap 2 is provided at the upper end of the fluid effusion bottle 1, and a drainage tube interface 3 and a connecting tube 4 are connected through the upper end of the first bottle cap 2. The drainage tube interface 3 is externally connected to the drainage tube, and the connecting tube 4 facilitates the flow of gas in the fluid effusion bottle 1 to the first water liquid 7 in the water seal bottle 6, thereby causing the first water liquid 7 to generate escaping bubbles.

[0024] Furthermore, a choke valve 5 is provided inside the connecting tube 4, and one end of the connecting tube 4 passes through the second bottle cap 8 and is connected with the first water liquid 7 inside the water seal bottle 6. The choke valve 5 is used to prevent the first water liquid 7 in the water seal bottle 6 from flowing back into the interior of the fluid collection bottle 1 through the connecting tube 4.

[0025] Furthermore, a first water liquid 7 is provided inside the water seal bottle 6 , and the first water liquid 7 is used to absorb the gas entering the first water liquid 7 through the connecting pipe 4 .

[0026] Furthermore, a second bottle cap 8 is provided at the upper end of the water seal bottle 6, and a liquid inlet 9 is connected to the upper end of the second bottle cap 8. The liquid inlet 9 facilitates the injection of the first water liquid 7 into the interior of the water seal bottle 6 through the liquid inlet 9 when the first water liquid 7 in the water seal bottle 6 is insufficient.

[0027] Furthermore, a sealing cover 10 is provided at the upper end of the second bottle cap 8 , and the sealing cover 10 is located at the upper end of the liquid inlet 9 . The sealing cover 10 is used to seal the liquid inlet 9 to prevent external bacteria from entering the interior of the water seal bottle 6 through the liquid inlet 9 .

[0028] Furthermore, a through tube 13 is opened through the side wall of the water seal bottle 6, one end of the through tube 13 passes through the side wall of the pressure regulating bottle 11, and the through tube 13 is located above the first water liquid 7. The through tube 13 facilitates the gas inside the water seal bottle 6 to enter the interior of the pressure regulating bottle 11 through the through tube 13.

[0029] Furthermore, a second water liquid 12 is provided inside the pressure regulating bottle 11 . The second water liquid 12 is located below the through pipe 13 .

[0030] Furthermore, a third bottle cap 14 is provided at the upper end of the pressure-regulating bottle 11, and a pressure regulating tube 15 and an aspirator interface 16 are connected through the upper end of the third bottle cap 14. The aspirator interface 16 is externally connected to a negative pressure suction device. The lower end of the pressure regulating tube 15 is located inside the second water liquid 12. The pressure regulating tube 15 is used to adjust the pressure inside the pressure-regulating bottle 11, thereby reducing the negative pressure that the patient's chest cavity needs to bear. The pressure regulating tube 15 can also be used to inject the second water liquid 12 into the pressure-regulating bottle 11.

[0031] Furthermore, the upper end of the pressure regulating tube 15 is fixedly connected to a curved connecting tube 17 , and the lower end of the curved connecting tube 17 is fixedly connected to an extension tube 18 , which is placed inside a collecting bottle 19 .

[0032] The working principle and instructions for use of the present invention are as follows: When it is necessary to perform negative pressure suction on a postoperative patient with pneumothorax, first the staff needs to take out the three-chamber closed drainage bottle, and then the staff needs to open the sealing cover 10 and inject sterile water for injection or normal saline into the interior of the water seal bottle 6 through the liquid inlet 9, and add 200ml of liquid to the 0 water level line of the water seal bottle 6. At this time, the lower end of the connecting tube 4 is submerged in the liquid surface by about 1-2cm, and then the sealing cover 10 and the liquid inlet 9 are sealed, and then sterile water for injection or normal saline is injected into the interior of the pressure regulating bottle 11 through the pressure regulating tube 15, and 500ml of liquid is added to the 8-12 water level line of the pressure regulating chamber. At this time, the pressure regulating tube is submerged in the liquid surface by about 11cm, and the aspirator interface 16 can be connected to the external negative pressure suction device, and then the drainage tube interface 3 is connected to the drainage tube. Then, the drainage tube is placed in the patient's chest cavity. At this time, under the action of the negative pressure suction device, the gas and liquid in the patient's chest cavity can be passed through the drainage tube and the drainage tube interface 3 into the interior of the fluid collection bottle 1. At this time, the fluid in the patient's chest cavity accumulates inside the fluid collection bottle 1, and its gas enters the first water liquid 7 in the water seal bottle 6 through the connecting tube 4. At this time, the first water liquid 7 produces escaping bubbles, thereby completing the suction and discharge of the gas and liquid in the patient's chest cavity. When the patient coughs, under the action of negative pressure suction, the water in the second water liquid 12 will continue to move upward through the pressure regulating tube 15, and then the second water liquid 12 will fall into the interior of the collection bottle 19 through the curved connecting tube 17 and the extension tube 18. Because there is water inside the collection bottle 19, the water of the second water liquid 12 will not be splashed significantly when entering the collection bottle 19.
