Invention content
The technical problem to be solved by the present invention is to：A kind of autocontrol catheter is provided to solve and secrete without wearing urinalThe painful topic of urinary system Disease, the quality of life to improve patient provide a kind of reliable utensil, and highly practical.
Technical solution is used by the present invention solves the above problems：Autocontrol catheter, including the ball that is connected on tube bodyCapsule, air valve and switching device, the switching device by switch valve, switch module through be cased with outside the valve rod of spring shaft connect into it is wholeBody is constituted, and the switch valve, which is matched by the steel ball to link into an integrated entity with valve rod one end with the valve seat for being connected with silica gel sheath, to be combined into, instituteSwitch valve is stated in one end of tube body；The switch module by installed in evacuating catheter button, be connected with the cross of springAxis, spring base, fixed seat and evacuating catheter connection form, and the switch module is mounted in the other end of tube body；The button withDescribed cross axle one end tight fit connection, the overall structure that the valve rod is pressed by flexible axle and needle tubing, the top of the valve rodThe lower end of steel ball is fixed on laser welding, the other end of valve rod passes through the through-hole in valve seat tube, and the end of needle tubing is put into springIn axis, the through-hole on cross-member ends convex block is passed through, then fixed after the end for being inserted into through-hole inner needle tube on convex block is bent 90 degreeOn cross axle, and adding additives make its fixation not fall out.
Compared with the prior art, the advantages of the present invention are as follows：This autocontrol catheter is not required to urinal is hung, and men and women, old and young are equalIt can be used, solve the painful topic of disease in the urological system patient, first pressing button is only needed, then through urinating mouth as normal personUrine in tube body is directly discharged in urinal and toilet, after urine is drained, hand button is unclamped and replys under spring forceTo original position, drain time oneself can grasp control, adjust, be put several times if urine is mostly just multiple rows of, if oliguria interval drain time is just grownA bit, protective cap is covered when not used, and protective cap is permanently affixed on catheter to lose, operate with it is simple and convenient,This autocontrol catheter selects silica gel and stainless steel material to make, and can be used two, three in catheter implantation patient's urethraMonth, it is durable, greatly reduce stress and the financial burden of patient, to substantially increase the quality of life of patient.
Specific implementation mode
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
Protective cap 1, the overall structure connected by urine lid 1-2, button cover 1-1, fixed ring 1-3, to make it when not usedWill not lose, be fixed on evacuating catheter 2 by fixed ring 1-3 snares, be mounted on evacuating catheter, button outer end face on, as Fig. 1,Shown in Fig. 2.
Evacuating catheter 2, a side external surface have urine mouth 2-1, have flange 2-2 among inner wall.
Embed sealing ring 15 in 11 outer periphery groove of button, an end periphery has a uniformly distributed four paws 11-1, among four paws end faceButton on have a blind hole, the end faces four paws 11-1 coordinate with evacuating catheter upper flange 2-2, the stroke that control button 11 moves inward.
There are the through-hole of polygon in spring base 4, centre, pass through convenient for urine.
Fixed seat 6, both ends are size cylinder, the intermediate rectangle being open for one side, viscous with lid 5 at the rectangular aperture of fixed seatConnect closing opening.
Cross axle 16 extends cross rib among plastic shaft and coordinates with the flange 2-2 on evacuating catheter, control button 11The stroke being displaced outwardly, does not allow it to deviate from from evacuating catheter, and one end is inserted into evacuating catheter 2 and is fastened blind among button 11In hole, there are the convex block 16-1 with cross through hole, and connecting spring 17,4 end face of spring base and 6 gluing of fixed seat on another endConnection, another end face are connected on evacuating catheter 2 with supersonic welding and constitute switch module, as shown in Figure 3.
Valve seat 14 is made of with frame 14-2 of the laser welding with pipe 14-3 two openings on seat 14-1, and ensures to manageOn center present 14-3, it is convenient for the connection with valve rod 13, spring shaft 12, the shape of groove and pipe 14-3 among frame 14-2Shape matches, as shown in Figure 4.
The overall structure that valve rod 13 is pressed by flexible axle 13-2 and needle tubing 13-1.
The top of the valve rod 13 is fixed on the lower end of steel ball 10 with laser welding, and the other end of valve rod 13 passes through valve seat 14The end of through-hole on pipe 14-3, needle tubing 13-1 is put into spring shaft 12, passes through the through-hole on cross-member ends convex block 16-1, thenIt is fixed on cross axle 16 after the end for being inserted into through-hole inner needle tube 13-1 on convex block is bent 90 degree, and adding additives make it fixIt does not fall out.One end of spring shaft 12 is tightly inserted into 6 small end cylinder of fixed seat, is integrally fixed with binder, spring shaft 12Other end laser welding is on pipe 14-3.
Lid 5 is sealed to binder the opening in fixed column 6, valve rod passes through cross axle 16 and button 11 after all installingEntirety moving up and down is connected into, as shown in figs. 3 and 5.
Switch valve increases leakproofness by the fixed silica gel sheath 9 in 14 upper end of valve seat, is connected with the steel ball 10 and valve seat 14 of valve rod 13Cooperation is formed, as shown in Figure 5.
Air valve 3, by installing the spring base 3-4 with spring 3-3, sealing ring 3-2, valve shaft lid 3-6, and valve in valve pocket 3-1The overall structure that set 3-1 and valve casing 3-5 is connected into supersonic welding.
Tube body 7, is made by silica gel material, one end You Liang branches, and air valve 3 is installed in short branch, is pacified on one end of long branchSwitch module is filled, is tightly inserted into long branch and is bonded using the fixed seat 6 on switch module, the other end installs the gas communicated with tube bodyCapsule 8 and switch valve, as shown in Figure 1.
First catheter is inserted into the urethra of patient, physiological saline is filled to sacculus 8 by air valve 3, catheter is made to be located inDo not deviate from urethra, when not used, button cover, the urine lid difference the cover on protective cap 1 in the end face of button 11 and is urinated into mouth 2-1On, it avoids touching the generation maloperation of button 11.
In use, taking away protective cap 1 reveals urine outlet 2-1, and make urine mouth face urinal or toilet, lifts catheter with handOn button 11, the valve rod 13 integral with button connects, which also follows, to be moved inward, make 13 top of valve rod steel ball 10 be detached fromContact between valve seat 14, i.e. switch valve are opened, and no longer cover tube body 7, and at this moment the urine in bladder enters tube body 7, and passes throughUrine mouth 2-1 is excreted, and until drained, is then unclamped hand, so that button 11 is displaced outwardly under the action of 17 power of spring, return to originalPosition, while the steel ball 10 for being connected thereto integral valve stem tip is driven by button, it moves down seal tube end outward, that is, openIt closes valve to close, urine cannot be excessive.So constantly interval uses, and is not required to wear urinal.
Air valve 3, the switch module that this catheter only has 7 front end of tube body stay in outside patient body, because its it is small can be by clothingClothes cover in not exposed, and patient can freely walk about, and social activity is carried out as normal person, then go to toilet and bleed off urine, completeThe full difficult situation for solving patient's painful topic, it is a kind of effective to be provided for patient, and the good utensil of using effect,Substantially increase the quality of life of patient.
