Description

Technical Field

[0001] The utility model relates to a safe closed chest drainage device, belonging to the technical field of medical products. Background Art

[0002] The chest closed drainage bottle is a drainage device routinely placed in patients after thoracotomy. Its purpose is to drain the accumulated air and fluid in the pleural cavity, reestablish the negative pressure in the pleural cavity, maintain the normal position of the mediastinum, and promote lung re-expansion. In the care of chest closed drainage, the drainage bottle is required to be 60-100cm lower than the plane of the chest wall drainage port, and rely on gravity drainage to prevent the liquid in the bottle from flowing back into the pleural cavity and prevent retrograde infection.

[0003] The shortcomings of the above products are as follows:

[0004] 1. It is inconvenient for patients to carry the water seal bottle when they get out of bed: When patients get out of bed or need to go out for examination, there is no suitable place to put the water seal bottle. It is inconvenient for patients to carry the drainage bottle. Medical staff sometimes let patients hold it to their chests, and sometimes let patients clamp the water seal bottle with their feet, causing the drainage bottle to be placed too high, which can easily cause the liquid in the bottle to flow back, and easily cause the liquid in the drainage bottle to tip over and affect the nursing staff's observation of the drainage volume; sometimes in order to accurately observe the drainage volume again, the drainage bottle needs to be replaced for the patient, which increases the economic burden on the patient and is also prone to nursing risks.

[0005] 2. The drainage bottle is prone to tipping over: When the patient gets out of bed and moves around, the bottle cannot always remain vertical. If it tilts, the liquid in the effusion cavity will tip over, affecting the medical staff's observation of the drainage volume.

[0006] 3. The steps for nurses to prepare chest closed drainage bottles are complicated, time-consuming and laborious. They need to prepare physiological saline and empty needles separately, and inject the liquid into the chest closed drainage bottle after multiple suctions. In addition, they must ensure aseptic techniques during the operation, and the cost cannot be included. In addition, in order to prevent dust in the air from entering the drainage bottle, nurses need to cover the chest closed drainage bottle filling port and pressure regulating channel with gauze, which is time-consuming.

[0007] It is necessary to design a safe closed chest drainage bottle to facilitate the safety of patients when they get out of bed or go out for examination, so as to better ensure the safety of patients and promote their recovery. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 The present invention is a schematic diagram of the structure of a safe closed chest drainage device. DETAILED DESCRIPTION

[0022] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.

[0023] The utility model provides a safe chest closed drainage device, such as Figure 1 As shown, it includes a drainage device body 6 and a liquid injection device 25. The drainage device body 6 is provided with a plurality of cavities, namely, a first liquid accumulation cavity 2, a second liquid accumulation cavity 4, a third liquid accumulation cavity 5, a pressure regulating channel 9, a suction controller cavity 10, a water seal cavity 11, and a water column fluctuation observation unit 12. Any two adjacent liquid accumulation cavities of the first liquid accumulation cavity 2, the second liquid accumulation cavity 4, and the third liquid accumulation cavity 5 are incompletely separated by a partition 3, that is, a through hole is provided at the top position between the first liquid accumulation cavity 2 and the second liquid accumulation cavity 4, and between the second liquid accumulation cavity 4 and the third liquid accumulation cavity 5 to allow the two adjacent liquid accumulation cavities to flow, and a one-way valve 22 is provided in the through hole, so that the patient's body fluid can only enter from the liquid accumulation cavity close to the output end of the drainage pipe 1 to the direction of the liquid accumulation cavity away from the output end of the drainage pipe 1, thereby avoiding the backflow of body fluid. The problem that the liquid in the liquid accumulation cavity will flow sideways after the drainage device body 6 is tilted is solved, thereby affecting the observation of the drainage volume by medical staff.

[0024] Now this anti-backflow valve is one-way, with a fixed upper end and an open lower section, and it exceeds the interval length of the cavity so that it can only move to the right but not to the left.

[0025] The top of the third fluid accumulation chamber 5 is connected to the output end of the drainage pipe 1. The drainage pipe 1 is provided with an anti-overflow valve 23 to prevent the body fluid in the drainage device from flowing back into the patient's body.

[0026] The top of the liquid accumulation chamber (i.e., the first liquid accumulation chamber 2) located at the very end is connected to the top of the water column fluctuation observation unit 12 through a connecting pipe 21, and the bottom of the water column fluctuation observation unit 12 is connected to the bottom of the water seal chamber 11. The top of the water seal chamber 11 is provided with two passages, one is connected to the top of the suction controller chamber 10, and the other is connected to the water seal liquid filling port 16 and the suction and exhaust port 20 respectively through the passage control valve 15. The passage control valve 15 can enable the water seal chamber 11 to selectively connect to the water seal liquid filling port 16 or the suction and exhaust port 20, and adjust the passage size of the suction and exhaust port 20. A sealing cover 17 is provided on the water seal liquid filling port 16, and a safety dust cap 13 is provided on the suction and exhaust port 20. At least one (in this embodiment, 2-3) vents 18 are provided on the side of the safety dust cap 13 to facilitate the discharge of gas. The safety dust cap 13 is a long cylindrical structure with a sealed top surface and openings on the bottom and sides. The sealing cover 17 and the safety dust cap 13 on the suction and exhaust port 20 are connected to the drainage device body 6 through the connecting line 19 to prevent them from falling and being lost. The bottom of the suction controller chamber 10 is connected to the bottom of the pressure regulating channel 9. Another safety dust cap 13 is provided on the top of the pressure regulating channel 9, and a vent 18 is also provided on its side. A circle of supporting feet 7 is provided around the bottom of the drainage device body 6, and a base 8 for supporting the drainage device body 6 is provided in the middle of the bottom of the drainage device body 6.

[0027] In this embodiment, the injection device 25 is an injection bag, and its injection port is funnel-shaped, which is convenient for the liquid in the injection bag to flow into the water seal cavity 11 without overflowing. The injection bag contains 80 ml of physiological saline or water for injection. Before use, the liquid can be added to the water seal cavity 11 by directly squeezing the injection device 25. The existing problem that nurses need to prepare physiological saline, empty needles, disinfectant, etc. and perform multiple suctions before injecting liquid into the water seal cavity 11 is solved.

[0028] A handle 24 is provided at the middle position of the top of the drainage device body 6, which makes it easier for patients to use and carry, thereby solving the problem that the hooks on both sides of the bottle body need to be connected with ropes to assist patients in carrying the device when getting out of bed.

[0029] The use process of the utility model is as follows:

[0030] First, remove the blocking cover 17 on the water seal filling port 16, insert the infusion port of the injection device 25 into the water seal filling port 16, and squeeze the physiological saline or water for injection in the injection bag (i.e., the injection device 25) into the water seal cavity 11 as required, so that the liquid level in the water seal cavity 11 is at least higher than the water level line (and the connecting port between the water column fluctuation observation unit 12 and the water seal cavity 11). When the required liquid is reached, adjust the passage control valve 15 so that the water seal filling port 16 is not connected to the water seal cavity 11, and the water seal cavity 11 is connected to the suction and exhaust port 20, and connect the drainage pipe 1 to the patient's body fluid output port.

[0031] When the patient's body fluid flows to a certain extent in the drainage device body 6, the liquid level in the water column fluctuation observation unit 12 is close to the connecting port between the water column fluctuation observation unit 12 and the water seal cavity 11, or the liquid level in the water column fluctuation observation unit 12 is lower than the liquid level in the water seal cavity 11 to a certain extent (as the body fluid enters the drainage device, the air between the effusion cavity and the water column fluctuation observation unit 12 will be compressed. As the pressure increases, the liquid level in the water column fluctuation observation unit 12 will be pressed into the water seal cavity 11 with lower pressure, so that the water column fluctuation observation unit 12 When the liquid level in the water column fluctuation observation unit 12 gradually decreases), adjust the passage control valve 15 so that the water seal liquid filling port 16 is connected with the water seal chamber 11, and the water seal chamber 11 is not connected with the air intake and exhaust port 20, squeeze the injection bag again, and add more physiological saline or water for injection into the water seal chamber 11, so that the liquid level in the water column fluctuation observation unit 12 is close to or flush with the liquid level in the water seal chamber 11, adjust the passage control valve 15 to the state where the water seal liquid filling port 16 is not connected with the water seal chamber 11, and the water seal chamber 11 is connected with the air intake and exhaust port 20, and continue to wait for the inflow of body fluid.
