[0016] Beneficial effects

[0017] 1. When the device is in use, the negative pressure component can realize automatic suction operation, which is convenient and flexible to use. At the same time, the suction rate of the device can be freely set and adjusted, which can meet the treatment needs of patients with different conditions. It is highly flexible, adaptable and practical.

[0018] When the diaphragm is in the reset state, the piston block is at the top under the action of the reset top spring. At this time, pressing the pressure rod downward can drive the piston block to move downward and store energy for automatic suction. During the pressing process of the pressure rod, external gas enters the piston cavity at the top of the piston block through the air inlet channel and the damping bleed hole, and the air inside the piston cavity at the bottom of the piston block can be discharged through the exhaust channel. During this process, the negative pressure one-way valve is always in a closed state. When the pressure rod is pressed to the bottom and the pressure rod is released, the piston block can be reset upward under the action of the reset top spring. When the piston block moves upward, the negative pressure generated inside the piston cavity realizes suction and decompression treatment of the patient through the negative pressure channel, and the exhaust one-way valve is in a closed state at this time, thereby stably realizing automatic suction and decompression treatment of the patient, which is convenient and flexible to use.

[0019] 3. When the piston block moves upward under the action of the return spring, the air intake one-way valve on the top of the piston cylinder is also in a closed state. Therefore, the air inside the piston cavity at the top of the piston block will be slowly discharged through the damping bleed hole, providing a damping effect for the upward movement of the piston block, thereby realizing the function of slow suction treatment for the patient and improving the patient's comfort during treatment.

[0020] 4. The upward movement of the piston block of the device allows the damping force (i.e., the suction rate) to be freely adjusted, thereby being able to adapt to the treatment of patients with different medical conditions. When it is necessary to adjust the damping force when the piston block of the device moves upward, it is only necessary to rotate the pressure rod. When the pressure rod rotates, the synchronization block can drive the adjusting rod to rotate through the synchronization groove, so that when the adjusting rod rotates, it can drive the positioning plate to move up and down through the rod body thread. When the positioning plate moves up and down, the initial compression degree of the reset spring is changed, thereby changing the force and rate of the piston block when it rebounds, and the adaptability is extremely strong.

When the device is in the reset state, a return spring 3021 is provided at the bottom of the piston block 302, and the two ends of the return spring 3021 are fixedly connected to the interior of the piston block 302 and the top of the positioning plate 303 respectively. At this time, the piston block 302 is at the top under the action of the return spring 3021, so that pressing the pressure rod 301 downward can drive the active The piston block 302 moves downward to store energy for automatic suction. During the pressing process of the pressure rod 301, external gas enters the piston chamber 2015 at the top of the piston block 302 through the air inlet channel 2013 and the damping air vent hole 2014, and the air inside the piston chamber 2015 at the bottom of the piston block 302 can be discharged through the exhaust channel 2012, and the negative pressure one-way valve 20111 is always in a closed state during this process. When the pressure rod 301 is pressed to the bottom and the pressure rod 301 is released, the piston block 302 can reset upward under the action of the reset spring 3021. When the piston block 302 moves upward, the negative pressure generated inside the piston chamber 2015 realizes suction and decompression treatment for the patient through the negative pressure channel 2011, and the exhaust one-way valve 20121 is in a closed state at this time, thereby stably realizing automatic suction and decompression treatment for the patient, which is convenient and flexible to use.

The piston block 302 and the positioning plate 303 are both inserted into the piston cavity 2015, and the positioning plate 303 is located at the bottom of the piston block 302. During use, the piston cavity 2015 can limit the movement trajectory of the piston block 302 and the positioning plate 303, so that the piston block 302 and the positioning plate 303 will not be skewed, twisted or rotated during movement, resulting in the device being stuck and failing or the adjustment function failing, and the use is stable.

[0040] The adjusting rod 202 has a threaded exterior, and the adjusting rod 202 is screwed to the interior of the positioning plate 303 through the threaded exterior of the rod body. In use, the upward movement of the piston block 302 of the device allows the damping force (i.e., the suction rate) to be freely adjusted, thereby being able to adapt to the treatment of patients with different medical conditions.
