Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0024] Example 1

[0025] The utility model solves the problem of the inconvenience of storing the second hose 5 after the patient has finished suctioning sputum by providing a hose clamp 62 for winding the second hose 5 and providing a test tube 61 for fixing the end of the second hose 5. At the same time, by removing the hose clamp 62 from the fixing plate 63, the test tube 61 can be disinfected and cleaned.

[0026] like Figure 1 As shown, a sputum suction negative pressure drainage device includes a negative pressure gauge valve 1, a negative pressure bottle 2, a liquid collecting bag 3, a first hose 4 and a second hose 5, and the negative pressure gauge valve 1 is installed on the negative pressure bottle 2. The negative pressure bottle 2 and the liquid collecting bag 3 are connected to each other through the first hose 4. One end of the second hose 5 is connected to the liquid collecting bag 3, and the other end is used for suctioning sputum from patients. A storage device 6 for storing the second hose 5 is provided on one side of the negative pressure bottle 2. The storage device 6 includes a test tube 61, a hose clamp 62 and a fixing plate 63, and the fixing plate 63 is arranged on the outside of the negative pressure bottle 2. The hose clamp 62 is clamped on the fixing plate 63 and is used to wrap and fix the second hose 5 that is too long. The test tube 61 is arranged on the side of the hose clamp 62 away from the fixing plate 63, and is used to insert the port of the second hose 5.

[0027] Since the hose clamp 62 and the fixing plate 63 are clamped together, the clamping structure can be unlocked by an external force, so that the hose clamp 62 and the fixing plate 63 can be detached from each other.

[0028] like Figure 2As shown, a fixing frame 611 is further provided at the inner top of the test tube 61. A rubber ring 612 is mounted on the fixing frame 611 to squeeze the end of the second hose 5. The rubber ring 612 narrows the entrance of the test tube 61, allowing the second hose 5 to squeeze the rubber ring 612 when inserted into the test tube 61. The friction generated by the rubber ring 612 on the second hose 5 prevents the second hose 5 from easily falling out of the test tube 61. The fixing frame 611 also supports the rubber ring 612, preventing it from falling into the test tube 61.

[0029] like Figure 3 As shown, further, the hose clamp 62 includes a first clamping plate 621 , a second clamping plate 622 and a hose winding roller 623 disposed between the first clamping plate 621 and the second clamping plate 622 .

[0030] Furthermore, at least four sets of arcuate grooves 624 are provided on the opposing sides of the first and second clamping plates 621, 622. These arcuate grooves 624 are used to hold the second hose 5 wound between the first and second clamping plates 621, 622. The arcuate structure conforms to the curved outer wall of the second hose 5, securing it more securely and preventing it from falling off.

[0031] Furthermore, the test tube 61 is arranged on a side of the first clamping plate 621 away from the second clamping plate 622 .

[0032] Furthermore, a sliding plate 6221 is provided on one side of the second clamping plate 622 close to the fixed plate 63. At least one clamping block 6222 is provided on both sides of the sliding plate 6221.

[0033] Furthermore, a sliding groove 631 for mounting the sliding plate 6221 is provided on one side of the fixing plate 63 close to the second clamping plate 622 .

[0034] like Figure 4 As shown, further, at least one latching groove 6311 is provided on both inner walls of the sliding groove 631. The sliding plate 6221 is fixed in the sliding groove 631 by means of a latching block 6222 and the latching groove 6311 being engaged with each other. Furthermore, the number of the latching grooves 6311 is the same as the number of the latching blocks 6222.

[0035] Working principle:

[0036] When in use, the negative pressure gauge valve 1 is opened to extract the gas in the negative pressure bottle 2 to form a negative pressure environment, thereby extracting the air in the liquid collection bag 3, so that the liquid collection bag 3 also forms a negative pressure environment. The liquid collection bag 3 absorbs the patient's sputum through the second hose 5.

[0037] After a patient has finished using the sputum suction negative pressure drainage device, the medical staff can wrap the excess second hose 5 around the hose winding roller 623 between the first clamping plate 621 and the second clamping plate 622. The end of the second hose 5 is then inserted into the test tube 61 for the next use. Alcohol disinfectant can be placed in the test tube 61 to disinfect the end of the second hose 5. This completes the storage of the second hose 5.

[0038] During disassembly, the hose clamp 62 is moved upward out of the sliding groove 631. During installation, the hose clamp 62 is inserted downward from the top of the sliding groove 631.
