Summary of the invention
Technical problem to be solved by this invention is: provide a kind of autocontrol catheter, without the need to wearing urinal, solves the painful topic of diseases of urinary system patient, for the quality of life of improving patient provides a kind of utensil reliably, and practical.
The present invention's adopted technical scheme that solves the problem is: autocontrol catheter, comprise sacculus, air valve and switching device that body connects, the entirety that described switching device has the valve rod of spring shaft to connect into by switch valve, switch module through overcoat is formed, described switch valve to be coordinated with the valve seat being connected with silica gel sheath by the steel ball linked into an integrated entity with valve rod one end and forms, and is arranged in one end of body; Described switch module is by button installation in evacuating catheter, the cross axle being connected with spring, and spring base and holder, evacuating catheter connect to form, be arranged in the other end of body, described button and described cross axle one end tight fit connection, the other end of described valve rod is fixed on the other end of described cross axle.
Compared with prior art, the invention has the advantages that: this autocontrol catheter does not need to join extension urinal, men and women, old and young all can use, solve the painful topic of diseases of urinary system patient, only need first pressing button, then the same with normal person through urine mouth the urine in body is directly discharged in urinal and toilet, urinate drained after, unclamp hands button and be returned to original position under spring force, but drain time oneself is grasped and is controlled, regulate, discharge several times if frequent micturition just more, if oliguria interval drain time is just long, protective cap does not cover by the used time, and protective cap is fixed on catheter and can not loses always, operate easy to use, this autocontrol catheter selects silica gel and stainless steel material to make, can two be used in a catheter patients with implantation urethra, three months, durable in use, greatly reduce stress and the financial burden of patient, thus substantially increase the quality of life of patient.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are further described.
Protective cap 1, the entirety connected into by urine lid 1-1, button cover 1-2, retainer ring 1-3 is formed, and in order to make it, the used time can not lose, and is fixed on evacuating catheter 2 by retainer ring 1-3 snare, is arranged on the outer face of evacuating catheter, button, as shown in Figure 1 and Figure 2.
Evacuating catheter 2, a side external surface has urine mouth 2-1, has flange 2-2 in the middle of inwall.
Embed sealing ring 15 in the groove of button 11 neighboring, an end periphery has uniform four paws 11-1, and the button in the middle of four paws end face has blind hole, and four paws 11-1 end face coordinates with evacuating catheter upper flange 2-2, the stroke that control knob 11 moves inward.
Spring base 4, there is polygonal through hole centre, is convenient to urine and passes through.
Holder 6, cylinder sized by two ends, centre is the rectangle of an opening, the bonding closing openings of rectangular aperture place lid 5 of holder.
Cross axle 16, extend cross rib in the middle of plastic shaft to coordinate with the flange 2-2 on evacuating catheter, the stroke of the outside movement of control knob 11, do not allow it deviate from from evacuating catheter, one end to be inserted in evacuating catheter 2 and is fastened in the blind hole in the middle of button 11, another termination has the projection 16-1 of band cross through hole, and linking springs 17, spring base 4 one end face is connected with holder 6 is gluing, and the supersonic welding of another end face is connected on evacuating catheter 2 and forms switch module, as shown in Figure 3.
Valve seat 14, be made up of the frame 14-2 of two opening part laser weld on seat 14-1 with pipe 14-3, and ensure, on the center that pipe 14-3 is present, to be convenient to the connection with valve rod 13, spring shaft 12, groove in the middle of frame 14-2 and the form fit of pipe 14-3, as shown in Figure 4.
The entirety that valve rod 13 is pressed into by flexible axle 13-2 and needle tubing 13-1.
The top laser weld of valve rod 13 is fixed on the lower end of steel ball 10, the other end of valve rod 13 is through the through hole on valve seat 14 pipe 14-3, be connected with the end of the needle tubing 13-1 of valve seat 14 and steel ball 10, put into spring shaft 12, through the through hole on cross-member ends projection 16-1, one end of spring shaft 12 is tightly inserted in holder 6 small end cylinder, be integrally fixed with binding agent, the other end laser weld of spring shaft 12 is on pipe 14-3, be fixed on cross axle 16 after again the end inserting through hole inner needle tube 13-1 on projection being bent 90 degree, and adding additives makes it fix to deviate from.
All install rear binding agent and lid 5 is sealed opening on fixed leg 6, valve rod connects into entirety moving up and down, as shown in Fig. 3, Fig. 5 by cross axle 16 and button 11.
Switch valve tightly overlaps silica gel sheath 9 by valve seat 14 upper end, and increase sealing, the steel ball 10 being connected with valve rod 13 coordinates with valve seat 14 and formed, as shown in Figure 5.
Air valve 3, by the spring base 3-4 installed in valve pocket 3-1 with spring 3-3, sealing ring 3-2, valve shaft lid 3-6, and the entirety that valve pocket 3-1 and valve casing 3-5 supersonic welding are connected into is formed.
Body 7, is made by silica gel material, one end You Liang branch, short branch installs air valve 3, switch module is installed in one end of long branch, utilize the holder 6 on switch module tightly to insert bonding in long branch, the other end installs the air bag 8 and switch valve that communicate with body, as shown in Figure 1.
First catheter is inserted in the urethra of patient; fill normal saline to sacculus 8 by air valve 3, make catheter be positioned in urethra not deviate from, not the used time; by the button cover on protective cap 1, urine lid difference cover cap on the end face and urine mouth 2-1 of button 11, avoid touching button 11 and maloperation occurs.
During use, take away protective cap 1 and reveal urine outlet 2-1, and make urine mouth just to urinal or toilet, the button 11 on catheter is lifted with hands, the valve rod 13 linked into an integrated entity with button is also followed and is moved inward, the steel ball 10 on valve rod 13 top is departed from and contact between valve seat 14, namely switch valve is opened, no longer cover body 7, at this moment the urine in Guang wing enters body 7, and excrete through urine mouth 2-1, until drained, then hands is unclamped, button 11 outwards movement is made under the effect of spring 17 power, get back to original position, driven the steel ball 10 of the valve stem tip linked into an integrated entity with it by button simultaneously, outwards move down and seal body end, namely switch valve cuts out, urine can not be excessive.So constantly interval uses, and does not need to wear urinal.
This catheter only has the air valve 3 of body 7 front end, switch module is stayed outside patient body, can be covered in by clothes because its volume is little and not expose, patient can freely walk about, doings are carried out as normal person, then go to toilet and bleed off urine, completely solve the difficult situation of patient's painful topic, for patient provide a kind of effective, and the good utensil of result of use, substantially increase the quality of life of patient.
