Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
As shown in Figs 1-4, it is to include in the embodiment of the present invention:
Air bag body 1, the air bag body 1 its volume satisfaction under unaerated form can be entered in bladder by ureter, the gas
In the deflated condition, shape is adapted utricule 1 with the shape size of bladder inner cavity；
Be connected with air inlet-outlet pipe 2 on air bag body 1, the present embodiment air inlet-outlet pipe 2 using removable plug connection type or
Integrally connected mode is connect with air bag body 1.
In addition, further including having injection needle unit 3, which includes needle tubing 31, the needle stand for installing needle tubing
32 and connect needle stand liquid supply pipe 33.The injection needle unit 3 can be conventional bladder needle size, be connected on air bag body 1
Enter the inserting needle channel 4 of air bag body 1 for injection needle unit 3, the inner wall of air bag body 1 is provided at least one injection point 11, injects
The periphery of point 11 and inserting needle channel 4 are fixedly connected with the traction rope 5 that band has a margin length between the import 41 of air bag body 1, institute
The needle stand 32 for the injection needle unit 3 stated is fastened on one end of the corresponding injection point 11 of traction rope 5, the confession of the injection needle unit 3
Liquid pipe 33 is placed in the inserting needle channel 4 and frees in and out setting, the injection needle list described under unaerated form of air bag body 1
The needle point 34 of member 3 is located at the gap adjacent inner side of injection point and is directed at injection point 11, and traction rope described in the present embodiment is elasticity
The elastic string of coefficient smaller (elasticity that micro-elasticity, the i.e. elasticity of the traction rope are less than air bag body), the elastic elongation of the elastic string
Length constitute the surplus length, the traction rope can also use medical flexible cord certainly.The traction rope
Effect is can to pull out the liquid supply pipe of injection needle unit 3 from inserting needle channel 4 when air bag body is inflated expansion,
And as air bag body moves together, to ensure that liquid supply pipe keeps feed flow to connect with needle stand.
As preferentially, the injection point 11 is multiple with the injection needle unit 3, and is arranged in a one-to-one correspondence,
And the liquid supply pipe 33 of multiple injection needle unit 3 is passed in and out from the inserting needle channel 4 side by side, by this setting, facilitates progress
It is injected while multiple injection points.
In addition, the air inlet-outlet pipe 2 and inserting needle channel 4 is arranged in parallel, and it is integrally placed at one and is connected to air bag
On body 1 and sectional area meets out of, ureter disengaging passes through integrated pipe 6.
In addition, be provided on the side wall of needle stand 32 described in the present embodiment longitudinal side channel 321 and with longitudinal side channel
One end of the transverse groove 322 of transverse intersection, the corresponding injection point 11 of the traction rope 5 is embedded on longitudinal side channel 321 and passes through
The binding strap (not shown) for being set to transverse groove 322 is fixed on needle stand.In addition, the end face that needle stand is connect with needle tubing 31 is set
It is equipped with shoulder face, to go out depth to the thorn of needle tubing and limit when needle tubing to puncture air bag body and is pierced by and is pierced into bladder inner wall
Safety is improved in position.In addition, needle tubing 31 punctures during air bag body passes through, the inner wall of air bag body 1 wraps needle tubing outer wall, two
Cooperation is sealed between person.
Include following steps by the implementing injection operating method of above-mentioned bladder medicament injection apparatus:
(1) the air bag body 1 of unaerated state is moved in bladder by ureter, air inlet-outlet pipe 2 and inserting needle channel 4 are set
In ureter；Before carrying out injection operation, decided by detection techniques such as the CT or X-ray of medicine or scopes
The position of the injection to be performed of bladder inner wall, and the injection point 11 on label air bag body, these above-mentioned inspections are gone according to these positions
Survey technology is conventional method medically, and the present embodiment is no longer described in detail；
(2) air bag body 1 is inflated by air inlet-outlet pipe 2, in gas replenishment process, with being gradually expanded for air bag body 1,
Traction rope 5 is stretched and is pulled corresponding liquid supply pipe 33 in air bag body 1 by drawing needle stand 32, until air bag body 1 is inflated
To close neighbour's bladder inner wall, stop inflation, the bladder inner wall injection position that the injection point on air bag body 1 as needs to inject；
(3) it is deflated in a small amount to air bag body 1, so that air bag body 1 is miniature, in the case where air bag body is miniature, needle tubing movement is slower than
The deflation of air bag body is miniature, and needle point punctures air bag body and is pierced by injection point and is pierced on the injection position of bladder inner wall；This setting
The discharge quantity so that the diameter sinking of the corresponding injection point position of air bag body 1 is adapted with the length of needle tubing 31 so that
Needle tubing can directly puncture air bag body 1 and be pierced into bladder inner wall；In deflation course, 1 rapid desufflation of air bag body, and it is corresponding
Needle tubing is shunk relatively slowly under the support of its liquid supply pipe, and therefore, air bag body 1 is punctured by needle point, and needle point is inserted into bladder inner wall
On；
(4) transfusion operation is carried out to liquid supply pipe, thus by drug injection to bladder inner wall；
(5) after injecting, by drawing liquid supply pipe 33 outward, needle tubing 31 is extracted from bladder inner wall,
And synchronous deflation, needle tubing is fallen back on into initial unaerated state；
(6) it after deflating to air bag body 1, is taken out from ureter by air bag body 1.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
