AI Technical Summary
Existing balloon inflation pressure pumps require two-handed operation during depressurization, which increases the complexity and difficulty of the operation, affects surgical efficiency, and is prone to slippage, leading to pressure deviation.
A balloon-expanded pressure pump was designed. By installing a clutch on the push rod assembly and using an elastic structure to separate the clutch from the push rod assembly, automatic and rapid pressure relief is achieved, reducing the difficulty of operation.
It enables automatic and rapid decompression operation, reduces the difficulty of decompressing the balloon expansion pressure pump, improves surgical efficiency, and reduces pressure deviation.

Abstract
Claims
1. A balloon inflation pressure pump characterized by, include: Housing assembly; The push rod assembly is partially inserted into the housing assembly; A clutch component has a sleeve hole, the clutch component is sleeved on the push rod assembly through the sleeve hole, the bottom of the sleeve hole has a clutch internal thread, the clutch internal thread is used to engage with the push rod assembly; A pressing structure is provided on the housing assembly and abuts against the clutch; The clutch component is connected to the housing assembly at its bottom via an elastic structure, and the tooth crest height of the sleeve hole is greater than the thread outer diameter of the push rod assembly. This allows the elastic structure to be compressed when the clutch component is pressed by the pressing structure, thereby separating the clutch component from the push rod assembly.
2. The balloon inflation pressure pump of claim 1, wherein, The housing assembly includes a housing structure and a limiting member disposed within the housing structure; The limiting member is sleeved on the push rod assembly. The limiting member has a limiting cavity that extends from top to bottom. The clutch is disposed in the limiting cavity through the elastic structure. When the clutch is engaged, its height is higher than the upper surface of the limiting member, so that the clutch abuts against the pressing structure.
3. The balloon inflation pressure pump of claim 2, wherein, The side wall of the limiting cavity is provided with a limiting slot, and the outer side of the clutch is provided with a limiting buckle. When the clutch engages with the push rod assembly, the limiting buckle engages with the limiting slot.
4. The balloon inflation pressure pump of claim 2, wherein, The sidewall of the limiting cavity is provided with multiple limiting bones, the clutch is inserted between the multiple limiting bones, and there is a preset limiting gap between the limiting bones and the clutch.
5. The balloon inflation pressure pump of claim 2, wherein, The shell structure includes: The pump casing is spindle-shaped and has anti-slip textures on it; Pump bottle, connected to the pump housing; The connecting component has one end connected to the pump bottle and the other end used to connect to the balloon catheter.
6. The balloon inflation pressure pump of claim 5, wherein, The housing structure also includes a digital pressure gauge, which is located at the front of the pump bottle.
7. The balloon expansion pressure pump according to claim 1, characterized in that, The pressing structure includes: A button is mounted on the housing assembly; The force-applying rod is flat and has an upward-protruding pressing protrusion at one end near the button for abutting against the button. The other end away from the button is hinged to the housing assembly. The middle part of the force-applying rod has a downward-protruding central protrusion for abutting against the top of the clutch.
8. The balloon inflation pressure pump of claim 7, wherein, The button includes: Press the panel; Two pressing columns are connected to the pressing panel and pass through the housing assembly; The pressing support bone is connected to the pressing panel, located between the two pressing columns, and abuts against the pressing protrusion; The pressing column near the force-applying rod has a rod groove for the force-applying rod to pass through.
9. The balloon inflation pressure pump of claim 2, wherein, The elastic structure includes an elastic substructure arranged symmetrically along the axis of the push rod assembly, the elastic substructure comprising: A groove is provided at the bottom of the clutch component; A guide post is located at the bottom of the limiting and receiving cavity; The elastic element has one end embedded in the groove and the other end sleeved on the guide post.
10. The balloon inflation pressure pump of claim 1, wherein, The push rod assembly includes: A drive push rod with external threads and a drive disc at one end; A sealing component, connected to the end of the drive push rod away from the drive disc, is used to seal the drive push rod and the housing assembly.
