Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a novel balloon expansion pressure pump. Background Art

[0002] The balloon pressure pump is used to inflate the medical balloon, causing it to expand. The expanded medical balloon directly expands the stenosis, or the expanded medical balloon expands the stent placed on it, which then expands the stenosis. After the expansion surgery is completed, the balloon pressure pump is used to depressurize the medical balloon so that the medical balloon can be removed from the human body cavity.

[0003] A Chinese patent with authorization publication number CN215231477U discloses a balloon dilatation pressure pump, comprising a measuring cylinder, a sleeve installed on the back of the measuring cylinder, a threaded push rod installed through the back thread of the sleeve, a steering shaft installed on the inner bottom wall of the sleeve, a stop plate connected to the outer surface of the steering shaft, a paddle installed on the top of the stop plate through the sleeve, a connecting tube installed on the front of the measuring cylinder, a test tube installed on the front of the connecting tube, and an air supply pipe installed on the front of the test tube.

[0004] In order to control the amount of gas filled and the pressure inside the medical airbag, the above patent installs a pressure gauge on the equipment to detect the pressure. When inflating, the staff needs to observe the value of the pressure gauge at all times, which is a cumbersome operation and also increases the cost of the equipment. Summary of the Invention

[0005] The purpose of the present invention is to address the technical problems existing in the background technology, and the present invention proposes a new type of balloon expansion pressure pump.

[0007] Preferably, a sliding block is slidably mounted on the inner side of the mounting tube, the spring abuts against the sliding block, an adjusting bolt is threadedly connected to the mounting tube, and the end of the adjusting bolt abuts against the sliding block.

[0008] Preferably, the end of the mounting tube away from the spring is connected to an exhaust pipe A, to which a sealing cover A is detachably connected; the air supply pipe B is connected to an exhaust pipe B, to which a sealing cover B is detachably connected.

[0009] Preferably, an anti-slip strip is bonded to the outer wall of the cylinder.

[0013] Preferably, the gas pipe A and the gas pipe B are respectively vertically connected to both sides of the installation pipe.

[0014] Compared with the prior art, the above-mentioned technical scheme of the present invention has the following beneficial technical effects: when working, the push plate is pulled to move outward, and at this time, the external gas enters the inner cavity of the cylinder through the air inlet pipe, and then pushes the push plate inward to a limited position. The movement of the push plate drives the movement of the piston plate, so that the gas in the cylinder passes through the air supply pipe A, the air vent, the air supply pipe B and the air supply connector in turn into the medical balloon. At the same time, a part of the gas enters the interior of the mounting tube through the air supply pipe, thereby slowly pushing the cylindrical piston to move toward the side of the spring.

The design of this structure can prevent overfilling of the medical airbag, has the function of overfill protection, and is safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1

[0019] like Figure 1-2 As shown, the present invention proposes a new type of balloon expansion pressure pump, including a cylinder 1, a mounting tube 8 and a gas supply connector 20; an anti-slip strip 19 is bonded to the outer wall of the cylinder 1; a piston plate 2 is slidingly provided inside the cylinder 1, a sealing rubber 3 is provided on the piston plate 2, one end of the piston plate 2 is connected to a piston rod 4, and the other end of the piston rod 4 is movable through the side wall of the cylinder 1 and connected to a push plate 5; the two ends of the cylinder 1 are respectively connected to an external pipe 21 and an air inlet pipe 22, and the air inlet pipe 22 is installed One-way valve C24; an air supply pipe A7 is connected between the end of the cylinder 1 away from the external communication pipe 21 and the mounting pipe 8, and a one-way valve B23 is installed on the air supply pipe A7. A air supply pipe B9 is connected between the other end of the mounting pipe 8 and the gas connection head 20. The air supply pipe A7 and the air supply pipe B9 are respectively connected vertically to the two sides of the mounting pipe 8. The air supply pipe B9 is connected to the exhaust pipe B15. The exhaust pipe B15 is detachably connected to the sealing cover B151. When the sealing cover B151 is opened, the inner side of the mounting pipe 8 can be opened. The gas is discharged, so that the cylindrical piston 10 is reset; the cylinder 1 and the mounting tube 8 are made of transparent materials, so that the staff can easily observe the situation inside the cylinder 1 and the mounting tube 8; the cylindrical piston 10 is slidably provided inside the mounting tube 8, and the cylindrical piston 10 is matched with the internal clearance of the mounting tube 8. A vent 1001 is provided on the cylindrical piston 10, and a spring 18 is provided on the inner side of the mounting tube 8. A limit ring 13 is provided on the side of the cylindrical piston 10 away from the spring 18 to limit The positioning ring 13 is fixed on the inner wall of the mounting tube 8. The positioning ring 13 can limit the cylindrical piston 10. A ventilation pipe 11 is provided between the end of the mounting tube 8 away from the spring 18 and the air supply pipe A7, and a one-way valve A12 is installed on the ventilation pipe 11; the end of the mounting tube 8 away from the spring 18 is connected to the exhaust pipe A14, and the exhaust pipe A14 is detachably connected to the sealing cover A141. The sealing cover A141 is opened to discharge the gas filled in the medical air bag.

[0020] The inner side of the external tube 21 and the inner side of the air inlet pipe 22 are both provided with a partition net; a sealing rubber ring 6 is fixed to the side of the cylinder 1, and the piston rod 4 is clearance-matched with the inner side of the sealing rubber ring 6; the provided partition net and sealing rubber ring 6 can prevent dust and debris from entering the interior of the cylinder 1.
