Lock Part 4 comprises end and near-end, is arranged on the near-end of push rod 2, and the end of Lock Part 4 is fixedly connected with the near-end of cavity 1, and the near-end of Lock Part 4 is fixedly connected with sleeve 5.Lock Part 4 is used to lock push rod 2, and the centre of Lock Part 4 has the open-work that push rod 2 is passed through, and its bottom has the screw thread with the threaded engagement of push rod 2; And Lock Part 4 is provided with the button 41 of locking push rod 2, when lifting button 41; The screw thread of the screw thread of push rod 2 and Lock Part 4 bottoms intermeshes; Push rod 2 is locked, and push rod 2 can not move and be merely able to carry out front and back rotatably through rotary handle 3 freely through the open-work of Lock Part 5; When pushing button 41 the time, push rod 2 is released, push rod 2 can be freely before and after action pass the open-work of Lock Part 5.Need to prove that the front and back of push rod 2 or spinning movement are all accomplished through operating grip 3.

Be provided with sleeve 5 in the handle 3, sleeve 5 is used for ccontaining push rod 2, and sleeve 5 is fixedly connected with the near-end of Lock Part 4.When pulled backwards handle 3, drive also action backward of push rod 2.At this moment, push rod 2 is just in the internal actions of sleeve 5.

Please refer to Fig. 3 A and Fig. 3 B, Fig. 3 A is the axial section of the balloon pressure pump of this utility model embodiment, and shown in Fig. 3 A, this balloon pressure pump comprises: cavity 1; Push rod 2, handle 3, Lock Part 4, button 41; Button spring 42, halfnut 43, sleeve 5, packing holder 6; Snap ring 7, O RunddichtringO 8, the first high-voltage tubes outlet 9, the second high-voltage tubes outlet 10.

Parts identical with Fig. 2 among Fig. 3 A repeat no more here.In addition, snap ring 7 is fixedly connected with packing holder 6, and snap ring 7 is used to connect push rod 2 and packing holder 6, and the end of push rod 2 designs for boss, and snap ring 7 is connected to the boss of push rod 2, thereby push rod 2 closely is connected with packing holder 6.And,, also be provided with O RunddichtringO 8 on the packing holder 6 for guaranteeing good sealing effectiveness.

The high-voltage tube that the end of cavity 1 is provided with in first high-voltage tube outlet, 9 and second high-voltage tube outlet, 10, the first high-voltage tubes outlet 9 is connected with pressure-display device, and the high-voltage tube in second high-voltage tube outlet 10 is connected with the foley's tube of inserting human body.

Wherein, pressure-display device further comprises: pressure transducer is used to detect the pressure signal in the pump housing and the foley's tube, and converts this pressure signal into the signal of telecommunication; Display unit is used to receive the signal of telecommunication, and shows pressure data according to the signal of telecommunication, parameters such as time and pressure curve, and can print through the data of exterior PC with whole process.

Fig. 3 B is the A-A radial section figure of Fig. 3 A, shown in Fig. 3 B, halfnut 43 is set in the Lock Part 4 is used to lock push rod 2, and the top of Lock Part 4 is buttons 41, and the bottom is provided with button spring 42.Locking push rod 2 when button 41 is lifted, push rod 2 are by halfnut 43 lockings, and push rod 2 is merely able to relative halfnut 43 rotations, and directly front and back action; Discharge push rod 2 when button 41 is pressed, push rod 2 is discharged by halfnut 43, directly front and back action of push rod 2.

In actual application, when actuating rod 2 backward, owing to need to produce negative pressure, so need be to push rod 2 pulled backwards, this is very inconvenient concerning user.Therefore, according to the embodiment of this utility model, on push rod 2, spring is set, the position of concrete spring setting please refer to Fig. 4 A.

As shown in Figure 4, according to an embodiment of this utility model, spring 11 is set at the near-end of push rod 2, spring 11 is enclosed in the sleeve 5 by push rod 2.When reality is used, at first, the button 41 of Lock Part 4 is made as down state (being that push rod 2 is released); Spring 11 is (near-end) driving handle 3 backward; Suck medicinal liquid in the cavity 1, inevitably also can suck little air, cavity 1 end is upwards lifted and driving handle deaeration forward; Foley's tube is sent into human body, and the balloon pressure pump is connected with foley's tube, and 41 springs, the 11 back pushing handles 3 that push button suck cavity 1 to form negative pressure with gas in the foley's tube and liquid.At this moment, downwards terminal because of cavity 1, medicinal liquid intercepts gas; (end) driving handle 3 forward pushes away and lifts button 41 when motionless and pin push rods 2, and rotary handle 3 moves forward push rod 2 rotations; Promote packing holder 6 simultaneously and move forward, make medicinal liquid get into foley's tube, medicinal liquid is pressed into foley's tube; Along with the increasing that is opened of the increase sacculus of pressure, support is expanded shaping, and spring 11 is compressed simultaneously; Under the supervision of X-ray machine, push button 41 once more, push rod 2 is released; Handle 3 forms negative pressure once more in motion backward under the effect of compressed spring 11 in the foley's tube, the liquid in the foley's tube is drawn out of; Sacculus shrinks with support and breaks away from, and extracts conduit out, accomplishes the installation of support.

In sum, through the balloon pressure pump that provides according to this utility model embodiment, pressurizeing, during operation such as pressure release and negative pressure, having simplified operating procedure, be very easy to user through simple structure.

The embodiment that the above is merely this utility model is not limited to this utility model, and for a person skilled in the art, this utility model can have various changes and variation.All within the spirit and principle of this utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of this utility model.
