Described catheter body is made by medical silication latex material.
The wall thickness of described sacculus I is preferably 2～3 times of wall thickness of sacculus II.
The design of the sacculus I in the two airbag safety type catheters of described two-chamber and the wall thickness of sacculus II obtains through Theoretical Calculation; at the cyst wall of sacculus I, be 2～4 times of wall thickness of sacculus II; particularly, in the time of 2～3 times, the two airbag safety type catheters of two-chamber can meet requirement fixing and protection urethra simultaneously.When sacculus I thickness is when the twice of sacculus II is following, injected media in sacculus, the volume that sacculus I and sacculus II swell is more or less the same, need to inject abundant medium and just can reach sacculus and the two airbag safety type catheters of two-chamber are fixed on to the requirement of urethra, but lose the function of protection urethra simultaneously; Sacculus I thickness sacculus II more than 4 times time; injected media in sacculus; sacculus II morphotropism is large, and volumetric expansion is larger, can play the two airbag safety type catheters of two-chamber are fixed on to the effect in urethra; and sacculus 1 morphotropism is little; when the sacculus II after swelling is under pressure, can not in time medium be clamp-oned in sacculus I, so when external force is drawn catheter; sacculus II is stressed and change in volume is little, does not have the effect of (transfer resistance) protection urethra.
Described catheter body main body is a hollow conduit, inserts urethra one end be provided with conduction hole at catheter body, and the catheter body other end is urethral catheterization chamber, by urethral catheterization chamber accent, can connect drainage bag.
Described airbag chamber terminal is the front end of catheter body.
The use principle of the two airbag safety type catheters of this practical novel two-chamber: the airbag chamber of the two airbag safety type catheters of two-chamber in catheter body front end edge airbag chamber terminal to airbag chamber accent direction successively adjacent sacculus I and the sacculus II of being provided with, because the wall thickness of sacculus I is 2～4 times of wall thickness of sacculus II, the ability that sacculus I bears pressure is large, and when injecting the media such as distilled water or normal saline or air in sacculus, sacculus I volumetric expansion is very little, and sacculus II volumetric expansion is larger, catheter is inserted into bladder from urethra, again in sacculus after injected media, relying on sacculus II volume to swell is fixed on catheter in bladder, prevent that the two airbag safety type catheters of two-chamber from skidding off from urethra, when unexpected use external force or while pulling out catheter by larger external force, sacculus II is under pressure, medium in sacculus II is under pressure and pushes the laggard sacculus I of entering, the smaller volume of sacculus II, it is large that sacculus I volume becomes, until sacculus I and sacculus II volume differences are when few, even extract the two airbag safety type catheters of two-chamber from urethra, can not cause compared with macrolesion urethra yet.
The beneficial effects of the utility model: this utility model is some defects that double channel foley balloon indwelling catheter of the prior art is existed, as, catheter inserts urethra, through sacculus, be fixed in bladder, can cause that patient is uncomfortable, patient is when careless, particularly when sleep, feel distending pain or when uncomfortable, often can remove to pull out catheter with hands, cause injury of urethra very large, simultaneously, when catheter inserts urethra, insertion depth relies on doctor's experience completely, and insert, deeply can cause that patient was uncomfortable, inserted shallow, sacculus incarceration causes patient's injury of urethra in urethra.This utility model has overcome the drawback that Foley catheter of the prior art exists completely, the two airbag safety type catheters of this utility model two-chamber are provided with inconsistent pair of sacculus of wall thickness, can play well catheter one end is fixed on to the effect in bladder on the one hand, the patient's injury of urethra causing in the time of effectively preventing from the other hand surprisingly extracting catheter under external force.In further preferred scheme of the present utility model, in double channel foley balloon indwelling catheter body insertion end, be designed with scale, greatly improve doctor's operation convenience, accuracy, also reduce patient due to the improper discomfort causing of Foley catheter intubating length, injury of urethra.
