Detailed description of the invention
As shown in Figure 1, a kind of balloon dilatation pressure pump, comprises Pressure gauge 4 and high-voltage tube 5 that push rod 1, the pump housing 3, the pump housing 3 are arranged, and the two ends of high-voltage tube 5 are connected with the outlet 31 of the pump housing 3 and threaded connector 6 respectively.The other end of threaded connector 6 is screw thread mouths, can be connected with other apparatuses such as foley's tubes easily.
Push rod 1 end arranges handle 11, and the top of push rod 1 is provided with buckle 13, and this buckle 13 can snap in piston seat 12, can rotate freely between buckle 13 and piston seat 12, but can not relative movement.The outer surface cover of piston seat 12 has piston 15, and piston 15 is positioned at the pump housing 3, and the two can move forward and backward along the inwall of the pump housing 3 simultaneously.Buckle 13 and piston seat 12 can rotate freely, and can ensure in pressure process, and piston 15 linearly moves with the surface of internal cavity of the pump housing 3, ensures good sealing property.Push rod 1 outer surface is provided with external screw thread 14.
The pump housing 3 is provided with locking device, generally be arranged on the top of the pump housing 3, locking device comprises button 2 and clamping block 30, button 2 and clamping block 30 link together, described clamping block 30 inserts in the pump housing 3 along the pump housing 3 radial direction, described button 2 is arranged on outside the pump housing 3, and button 2, clamping block 30 can move radially along the pump housing 3, but button 2, clamping block 30 cannot moving axially along the pump housing 3.
Spring 22 is provided with between the top of clamping block 30 and the pump housing 3 inwall, clamping block 30 is provided with the inserting hole 31 being greater than push rod 1 body of rod, push rod 1 passes through inserting hole 31, and the hole wall of described inserting hole 31 is provided with the screw thread curved surface 21 corresponding with external screw thread 14 on push rod 1; Under the effect of spring 22, the screw thread curved surface 21 of inserting hole 31 is meshed with external screw thread 14 on push rod 1, stops push rod 1 to move along the axial push-and-pull of the pump housing 3; When pressure is applied to button 2, clamping block 30 is to the pump housing 3 internal motion, the screw thread curved surface 21 of inserting hole 31 is separated with external screw thread 14 on push rod 1, push rod 1 is no longer by the constraint of inserting hole 31 female thread curved surface 21, can move along the axial push-and-pull of the pump housing 3, push rod 1 can move along the axial push-and-pull of the pump housing 3.During the release of button 2 upward pressure (release button 2), spring 22 promotes button 2, clamping block 30 resets, and the screw thread curved surface 21 of inserting hole 31 is meshed with external screw thread 14 on push rod 1, stops push rod 1 to move along the axial push-and-pull of the pump housing 3.
When the pump housing 3 being arranged two locking devices, when two buttons 2 are pressed simultaneously, on clamping block 30, the screw thread curved surface 21 of inserting hole 31 is separated disengagement with the external screw thread 14 of push rod 1, can freely be pushed in the pump housing 3 by handle 11 or withdraw push rod 1.
When two buttons 2 are not pressed simultaneously, can guarantee to have at least the screw thread curved surface 21 of inserting hole 31 on a clamping block 30 to keep and the engaging of the external screw thread 14 of push rod 1.Push rod 1 can not move along the axial push-and-pull of the pump housing 3, the external screw thread 14 of push rod 1 can only be moved along screw thread curved surface 21 spiral of inserting hole 31 by swing handle 11.When push rod 1 spiral moves, the piston 15 of its front end also can realize moving forward and backward, and effectively can prevent the operation of pressure release by mistake like this.
The inner chamber 32 of the pump housing 3 can pour into the solution such as contrast agent or normal saline, when rotating handles 11 mobile piston 15, the pressurization of the solution of the pump housing 3 inner chamber 32 can be infused into assigned address.The outer surface of the pump housing 3 has scale, the distance of observable piston movement.
Pressure gauge 4 can show the pressure of the solution of the pump housing 3 inner chamber 32, and the dial plate of Pressure gauge 4 is with fluorescent functional.
When normally using, can first by the infusion such as contrast agent or normal saline in compression pump.First press two buttons 2 simultaneously, remove the screw-threaded engagement between external screw thread 14 on screw thread curved surface 21 on inserting hole 31 hole wall and push rod 1, then pumpback push rod 1 makes the inner chamber 32 of the pump housing 3 form negative pressure, and solution enters after compression pump can release button 2, locked piston 15.
In pressurization, under the effect of spring 22, button 2 is in the state of upspringing, and push rod 1 cannot along the pump housing 3 axially rectilinear movement.Rotating handles 11, push rod 1 can threadingly spiral shift-in, thus drive piston 14 axially straight line move forward, realize the object of pressurization.Pressure gauge 4 can the size of monitoring pressure.
During pressure release, can press two buttons 2, the screw thread curved surface 21 on disengagement inserting hole 31 hole wall engages with the external screw thread 14 on push rod 1, and push rod 1 can freely move forward and backward simultaneously.Owing to being subject to the effect of internal pressure, piston 15 can withdraw, and realizes the object of pressure release.
Above-described embodiment limits this utility model never in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection domain of the present utility model.
