Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a portable sputum suction device. Background Art

[0002] Coughing and sputum are common symptoms of respiratory inflammation. Patients need to use a suction pump for auxiliary treatment during the treatment process to be able to suction out sputum in time. As a medical device, the suction pump inserts a straw into the mouth, nasal cavity, artificial airway, etc., uses negative pressure to suck out respiratory secretions, thereby keeping the respiratory tract unobstructed and preventing certain diseases and complications. There are mainly electric negative pressure suction pumps and simple manual suction pumps on the market. Manual suction pumps have the advantages of high portability and low cost compared to electric suction pumps.

[0003] When using a manual suction device, you need to hold the suction device and repeatedly pull the handle, and operate the suction tube to suction sputum. During the suction operation, the suction tube should be appropriately rotated or moved up and down according to the actual situation to facilitate all-round suction. The sputum after suction should be cleaned at any time to avoid entering the suction device. However, its structural design is a gun-shaped structure composed of a suction tube, a piston, and a sputum bottle, which occupies a certain storage space and is inconvenient to carry. For this reason, we propose a portable suction device. Utility Model Content

[0006] Preferably, a threaded structure corresponding to the sputum bottle is provided on the outside of the mounting block, the sputum bottle is detachably connected to the outside of the mounting block, a connecting pipe is fixedly connected to the top of the sputum bottle, and a one-way valve is provided inside the connecting pipe.

[0007] Preferably, a threaded structure corresponding to the fixed shell is provided inside the mounting base, the fixed shell is detachably connected to the inside of the mounting base, the tail end of the fixed shell is fixedly connected to a limiting ring, the movable shell is slidably connected to the inside of the fixed shell, and the top of the movable shell is fixedly connected to a second sealing ring.

[0008] Preferably, a piston is slidably connected to the interior of the movable housing, a sealing ring is fixedly connected to the exterior of the piston, a pull rod is fixedly connected to the bottom of the piston, and a pull block is fixedly connected to the bottom of the pull rod.

[0009] Preferably, the sealing plug is rotatably connected to the top of the mounting base via a rotating shaft, a hole corresponding to the reserved hole is provided inside the first sealing ring, and the gas inside the fixed housing can be discharged through the reserved hole.

[0010] Preferably, the top cross-sectional area of ​​the limiting ring is larger than the bottom cross-sectional area of ​​the limiting ring, the height of the limiting ring is equal to the height of the pull block, and the pull block can be clamped inside the limiting ring.

[0011] Preferably, a hole corresponding to the pull rod is opened at the bottom of the movable housing, and the pull rod is slidably connected to the inside of the hole. The pull block can pull the pull rod to drive the piston to move.

[0012] Beneficial effects:

[0013] 1. The portable sputum suction device forms a sealed cavity by installing a base, a fixed shell, and a movable shell. The piston is pulled to move inside the sealed cavity to suck sputum into the sputum bottle. During this process, it is necessary to hold the fixed shell and press the reserved hole with a finger to avoid air leakage, and then cancel pressing the reserved hole. Under the action of the one-way valve, the gas is discharged from the inside of the sealed cavity through the reserved hole to complete the resetting of the piston. After use, the sputum bottle is removed, the fixed shell is installed, and the pulling block is pressed to move the mobile shell into the fixed shell, and the pulling block moves to the inside of the limiting ring, thereby reducing the space occupied by the sputum suction device and increasing portability.

[0014] 2. The portable sputum suction device uses a spiral tube to prevent backflow. When holding the fixed shell and using the sputum suction tube, the fixed shell will be placed at an angle, and the spirally arranged pipe can effectively prevent the material in the sputum bottle from flowing back into the sputum suction tube, thereby achieving the effect of preventing backflow. The plug can seal the installation base when the device is idle to prevent dust from falling in. The structure is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS
