[0002] The Department of Cardiovascular Medicine is a clinical department set up by the Department of Internal Medicine of hospitals at all levels for the purpose of diagnosing and treating cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, irregular heartbeat, myocardial infarction, cardiomyopathy, myocarditis, myocardial infarction and other cardiovascular diseases. During the treatment process, the Department of Cardiovascular Medicine sometimes needs to use drainage devices to drain patients.
[0003] After searching, it is found that a drainage device is disclosed in Chinese patent documents [Application No.: 201920204066.0; Announcement No.: CN 209630299 U]. This drainage device relates to the field of medical technology. The drainage device comprises a shell, a control mechanism is fixedly connected to the left side of the shell, a catheter is provided through the right side of the top of the shell, a joint is fixedly connected to the end of the catheter away from the shell, a partition is provided in the inner cavity of the shell, a transformer mechanism is provided between the partition and the left side of the inner cavity of the shell, a driving mechanism is fixedly connected to the left side of the top of the shell, and a rotating bolt is fixedly connected to the output end of the driving mechanism through a coupling. The drainage device, through the improvement of the transformer mechanism, and the coordinated use of the side tube, the flow control valve, the partition, the driving mechanism and the rotating bolt, enables the drainage device to monitor the air pressure in the catheter well, avoiding damage to the patient's body due to the failure to stop decompression in time after the joint adsorbs the inner wall of the patient's body.
[0004] Although this patent can monitor the air pressure in the catheter very well, when performing drainage operation, the medical staff places the drainage bottle on the nursing table or holds the drainage bottle in hand, and squeezes the air bag with the other hand to discharge the air in the air bag, thereby generating negative pressure in the drainage bottle, so that the accumulated water enters the drainage bottle through the puncture needle and drainage tube. However, the existing drainage bottles are usually unable to be fixed, resulting in the risk of falling or tipping over, thereby affecting the efficiency of the drainage operation and posing a safety hazard.

An air valve 1 is fixed in the air bag 2, and a puncture needle 14 is connected to the drainage tube 15.
[0029] The working principle of the utility model is: the medical staff squeezes the airbag 2 with one hand, and the air in the airbag 2 is discharged, thereby causing the drainage bottle 4 to generate negative pressure, so that the accumulated water enters the drainage bottle 4 through the puncture needle 14 and the drainage tube 15, completing the drainage work, and then the clamping groove is buckled into the nursing bed board, and then the regulating wheel is rotated to make the bolt 8 continuously push the pressure block 7, and the pressure block 7 further presses the nursing bed board, thereby realizing the fixed connection between the clamping frame 9 and the nursing table board, so that the medical staff does not need to hold the drainage bottle 4 all the time, thereby improving the drainage efficiency.
[0030] A plurality of fine ratchet teeth 6 are fixed on the top surface of the pressing block 7 .
[0031] By adopting the above structure, the contact friction between the pressing block 7 and the nursing table board can be increased through the ratchet 6, so as to better achieve the fixing stability of the clamping frame 9 and the nursing table board.
