Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adjustable chest drainage device. Background Art

[0002] In clinical treatment, chest drainage is a common medical procedure, primarily used to drain chest diseases such as hemothorax, pneumothorax, and empyema, as well as during recovery after thoracotomy. This technique involves placing a drainage tube in the patient's chest cavity, connected to a closed drainage bottle or bag, to remove air and fluid from the chest cavity, thereby helping the lungs to resume normal function.

[0003] The chest drainage devices currently on the market generally have a relatively simple structure, mainly consisting of a drainage tube and a drainage bottle (bag). However, this traditional chest drainage system has some shortcomings in practical applications:

[0052] Working principle:

[0053] Medical staff move the support rod 7 to a suitable position and then use the hook 72 to fix the support bracket 6 to the support frame. The dual-brake universal wheel 40 can be locked or unlocked to fix or move the support frame. The hook 72 is convenient for hanging an infusion bottle to facilitate infusion.

[0054] Medical staff controls the motor 80 to rotate the lead screw 8, thereby driving the sliding rod 62 on the support frame 6 to move up and down, thereby adjusting the height of the support frame 6. The height of the support frame 60 is 60cm-100cm from the ground. In this way, the position of the drainage bottle 1 can be precisely controlled to meet the needs of different patients.

[0055] Monitor the drainage liquid volume. By observing the first scale line 4 on the drainage tube 2, medical staff can intuitively understand the volume of the liquid in the drainage tube 2, thereby judging whether the drainage is smooth and whether it can flow into the drainage bottle 2, and thus know the patient's chest fluid discharge status;

[0056] Adjust the drainage speed. According to the liquid volume displayed on the first scale line 4, the medical staff can adjust the adjustment mechanism 3 to change the opening and closing degree of the drainage tube 2, thereby controlling the drainage speed to meet the specific needs of the patient.

[0057] When a new drainage bottle 1 needs to be replaced, the new drainage bottle 1 is placed on the temporary storage plate 9 for temporary storage, the bolt 610 is rotated to make it away from the side plate 61, and the full drainage bottle is replaced;

[0058] Rotating the adjusting wheel 35 can drive the adjusting wheel 35 to move tiltedly under the guidance of the inclined groove 33, thereby squeezing the drainage tube 2, which can not only adjust the opening and closing degree of the drainage tube 2, but also adjust the drainage and discharge speed, thereby improving practicality;

[0059] One end of the drainage tube 2 is inserted into the top of the drainage bottle 1 and fixed by the connecting cap 13 and the insertion tube 14, ensuring the sealing and stability of the drainage system. The bottom of the bottle body 11 is protected by the base 17. The exhaust pipe 18 is used to discharge the gas in the drainage bottle 1 to prevent gas accumulation from affecting the drainage effect. It is convenient to balance the internal and external air pressure and facilitate drainage.

[0060] The second scale line 16 monitors the total volume of the drainage liquid. The second scale line 16 helps medical staff monitor the total volume of the liquid in the drainage bottle 1, thereby better managing the drainage process and avoiding overfilling of the drainage bottle 1;

[0061] The drainage effect can be evaluated by comparing the readings of the second scale line 16 at different time points, so that the medical staff can evaluate the drainage effect and determine the recovery of the patient.

[0062] The basic principle and main features of the present application and the advantages of the present application are shown and described above. It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
