Detailed Implementation

[0021] The specific embodiments of this utility model will be further described and illustrated below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a user-friendly manual suction device includes a suction tube 1, a suction cylinder 2, a handle 3, a suction valve cylinder 4, and a sputum collection assembly 5. The handle 3 is connected to the suction cylinder 2 and is equipped with a piston rod 6, which is slidably installed in the suction cylinder 2. The suction cylinder 2 is connected to the suction valve cylinder 4. A spring body 61 is fitted onto the piston rod 6 in the suction cylinder 2, allowing the piston rod 6 to return to its original position automatically, making operation more flexible and convenient. The front end of the suction valve cylinder 4 has a liquid inlet 41, which is movably connected to the suction tube 1. The suction tube 1 has a connector 11 at its connection point. The lower end of the suction valve cylinder 4 has a liquid outlet 42, which is movably connected to the liquid outlet 42. One-way valve bodies 7 are respectively provided at the liquid inlet 41 and the liquid outlet 42.

[0023] like Figures 1 to 4 As shown, the sputum collection assembly 5 includes an upper cover 51, an annular retaining ring 52, and a sputum collection bag 53. The upper end of the upper cover 51 has a connecting port 511, which is movably connected to the outlet 42. The sputum collection bag 53 is movably fitted within the annular retaining ring 52, with the upper cover 51 movably retaining the upper part of the annular retaining ring 52 and fixing the sputum collection bag 53 to the annular retaining ring 52. The connecting port 511 is movably screwed into the outlet 42. An external thread 512 is provided on the outer wall of the connecting port 511, and an internal thread 421 is provided on the inner wall of the outlet 42. The external thread 512 and the internal thread 421 are correspondingly screwed into each other. The outer side wall of the annular retaining ring 52 is provided with a retaining rubber ring 521, which is fitted and secured to the inner side wall of the upper cover 51.

[0024] When using:

[0025] Assembly of the sputum collection assembly: First, cover the clean sputum collection bag 53 onto the annular retaining ring 52, and fold the opening of the sputum collection bag 53 downwards onto the upper part of the outer side wall of the annular retaining ring 52. Then, movably retain the upper cover 51 onto the upper part of the annular retaining ring 52, and fix the sputum collection bag 53 onto the annular retaining ring 52.
