Description

Sting device is arranged outside internal hydrops

Technical field

The utility model is related to medical apparatus, and sting device is arranged outside more particularly, to a kind of internal hydrops being conveniently operated.

Background technology

When a certain position prevents hydrops bacterium infection, take out there are progress puncture suction hydrops when hydrops, is needed in patient body The hydrops gone out can be also detected, with auxiliary diagnosis disease property.It is existing clinically as follows to the operation of the aspiration procedure of hydrops：It is first First quasi- point of puncture is anaesthetized with lidocaine；Then it is punctured according to preoperative imaging localization with an elongated puncture needle corresponding Depth, puncture needle rear end are connected with syringe, after can pump out liquid from puncture needle, seal wire are inserted into out of puncture needle and is worn Point is pierced, puncture needle is extracted later, conduit is inserted into patient body along seal wire；Finally extract seal wire, fixed catheter, external drainage Operation can be completed in bag；Whole operation step is various, and operating process is very cumbersome, and the operating time is long；In a variety of instrument insertion bodies, Operational risk is big（Such as carry out being easy air inlet when thoracentesis, easily lead to pneumothorax；Since operation walks when for another example carrying out abdominocentesis It is rapid more, therefore the possibility for damaging abdominal viscera increases, the risk of human infection increases）；In addition, due to the drainage channel of conduit Diameter is smaller, and when containing impurity in drainage-fluid, easily obstruction conduit, and the mode pumping liquid of external drainage bag is easy out Existing reflux, leads to human infection.

Invention content

The utility model aim is that provide internal hydrops a kind of simple in structure, easy to operate arranges sting device outside.

To achieve the above object, the utility model can take following technical proposals：

It arranges sting device outside internal hydrops described in the utility model, including soft punctures conduit and is led from described puncture The puncture guiding needle that pipe rear end penetrates, front end is pierced by is communicated with drainage pipe, in the drainage tube close to puncturing at rear end of conduit Road outer end is communicated with rubber sacculus, and clip is provided on drainage pipe；In the connection of the rubber sacculus and the drainage pipe Place is provided with breather cheek valve, and the row with one-way exhaust valve is offered on the rubber sacculus side wall opposite with the breather cheek valve Gas port；A pair of anti-reflux device is arranged at intervals in drainage pipe between the clip and the rubber sacculus, described in two A bar shaped draining hole is offered on drainage pipe tube wall between anti-reflux device along its length, is sealed on the draining hole It is fixed with the soft drainage bag being connected with drainage pipe, rigid support rib is provided at the opening's edge of the draining hole；Institute It states drainage bag bottom and is communicated with the drain pipe with end cap.

The utility model advantage be it is simple in structure, it is easy to operate, without repeatedly carry out puncture procedure, simplify operation step Suddenly, the operating time is saved, reduces operational risk.The rubber sacculus of the external one-way ventilating in drainage pipe outer end, by squeezing rubber Sacculus can play the role of vacuum suction hydrops in patient body, and suction greatly increases, and avoid impurity from blocking and puncture conduit and draw Flow tube road；Bar shaped draining hole is opened up on drainage pipe tube wall, and seals the drainage bag that is connected on draining hole, is not necessarily to external drainage Bag, avoids draining hole open in air, prevents germ contamination draining hole；In addition, being set in the drainage pipe of draining hole both sides Anti-reflux device is set, hydrops reflux is avoided；Meanwhile rigid support rib is set at the opening's edge of draining hole, supporting drainage mouth avoids Rubber sacculus suction is excessive to cause draining hole to occlude, and prevents pressure from can not conduct to patient's body cavity, ensures that drainage is unobstructed.

Specific implementation mode

As shown in Figure 1, 2, sting device is arranged outside internal hydrops described in the utility model, including the soft puncture of slender type is led Pipe 1 and from puncture conduit 1 rear end penetrate, the puncture guiding needle 2 that front end is pierced by, draws close to puncturing 1 rear end of conduit and being communicated with Flow tube road 3（Drainage pipe 3 can be soft pipeline or hard pipeline）, it is communicated with rubber sacculus 4 in 3 outer end of drainage pipe, Clip 5 is provided on drainage pipe 3；The junction of rubber sacculus 4 and drainage pipe 3 is provided with breather cheek valve 6, and it is unidirectional The exhaust outlet 8 with one-way exhaust valve 7, breather cheek valve 6 and unidirectional row are offered on opposite 4 side wall of rubber sacculus of intake valve 6 The setting of air valve 7 can ensure that rubber sacculus 4 only has the function of attracting hydrops when squeezing；Clip 5 and rubber sacculus 4 it Between drainage pipe 3 in be arranged at intervals with a pair of anti-reflux device 9（Anti-reflux device 9 can prevent hydrops reflux）, two anti-reflective A bar shaped draining hole 10 is offered on 3 tube wall of drainage pipe between stream device 9 along its length, sealing is solid on draining hole 10 It is connected with the soft drainage bag 11 being connected with drainage pipe 3, rigid support rib 12 is provided at the opening's edge of draining hole 10, is helped Supporting drainage mouth 10 avoids 4 suction of rubber sacculus is excessive draining hole is caused to occlude, and ensures that drainage is unobstructed；In 11 bottom of drainage bag It is communicated with the drain pipe 14 with end cap 13, facilitates the discharge of hydrops in drainage bag 11.

It is as follows that sting device operating process is arranged outside internal hydrops described in the utility model：

Quasi- point of puncture is anaesthetized with lidocaine first；Then in the external syringe 15 in the rear end of puncture guiding needle 2, According to the paracentesis depth of preoperative imaging localization, conduit 1 will be punctured and puncture guiding needle 2 is pierced into patient body, until syringe 15 can pump out extraction puncture guiding needle 2 after hydrops；Drainage pipe 3 and drainage bag 11 are fixed later, squeeze rubber sacculus 4, Pass through negative-pressure ward hydrops.Hydrops can be flowed into through draining hole 10 in drainage bag 11, and when hydrops is more in drainage bag 11, clamping is drawn Clip 5 on flow tube road 3 opens the end cap 13 on drain pipe 14, hydrops is expelled in collection vessel；When 11 inner product of drainage bag When liquid is drained, end cap 13 can be closed, unclamps clip 5, continues to squeeze 4 suction hydrops of rubber sacculus, operation is until patient repeatedly Internal hydrops is all discharged.
