Embodiment Construction
[0015] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] Depend on Figure 1-6 It can be seen that the present invention includes a housing 1, and the housing 1 is provided with a cylinder 2 that is placed horizontally and can move up and down in the housing 1. The cylinder 2 is provided with a piston 3 that can slide left and right in the cylinder 2. The piston 3 The left side of 3 and the cylinder body 2 form a suction chamber 4, the first spring 5 is connected between the right end of the piston 3 and the right side wall of the cylinder body 2, and the first spring 5 is always in a stretched state, and the right end of the piston 3 is connected with a piston The rod 10, the right end of the piston rod 10 runs through the right side wall of the cylinder body 2 and is placed outside the cylinder body 2. The casing 1 is provided with a top block 6 which is placed on the...

The utility model relates to a stable thoraco-abdominal puncture drainage device, which can replenish the negative pressure in the suction chamber at any time during the suction process to ensure thesuction stability and efficiency. The technical scheme comprises a shell, a cylinder block is arranged in the shell, a piston is arranged in the cylinder block, a first spring is connected between theright end of the piston and the right side wall of the cylinder block, a piston rod is connected at the right end of the piston, a top block is arranged in the shell, a screw rod is inserted into theupper and lower end faces of the top block, and the screw rod is rotatably connected with the top block; the end face of the top block near the cylinder block is provided with a groove, An upper sidewall in that groove is hinge with a top plate, the top plate is inclined to the right and the bottom, the top block is located at the lower part in the initial state, the first spring is in the longest stretching state, the cylinder block is moved downward so that the piston rod can be pushed against the top plate, the piston rod can always contact with the top plate under the action of the firstspring, the cylinder block is moved downward, the piston is moved to the right, and the volume of the suction chamber is increased; the invention is novel in conception and use.
Description
technical field [0001] The invention relates to the technical field of thoracoperitoneal puncture and drainage, in particular to a stable drainage device for thoracoperitoneal puncture. Background technique [0002] Negative pressure drainage is widely used in clinical practice. It is mainly aimed at postoperative patients. There are many pressure drainage devices, such as artificial negative pressure drainage balls, artificial negative pressure drainage bottles, central negative pressure drainage bottles, etc. [0003] These negative pressure drainage devices will not be able to stabilize the negative pressure and adjust the negative pressure according to the patient's own conditions during the negative pressure manufacturing process; the central negative pressure drainage bottle can only rely on external power such as negative pressure suction devices to generate negative pressure. At this time, the negative pressure suction device will not work. [0004] Therefore, it i...
