Description

A kind of catheter with washed bladder switch

Technical field

The utility model belongs to a kind of catheter with washed bladder switch.

Background technique

Currently, used in hospital to patient's urethral catheterization catheter front end be contact pin, rear portion trident be formed separately drainage tube, Washed bladder pipe and closing charging pipe, drainage tube are held in urine bottle for leading to urine in patient's bladder, and closing water-filling is effective Processing solution is injected into patient's bladder when necessary in patient's bladder, washed bladder is effective in positioning insertion pin head.In use, The nozzle of drainage tube and closing charging pipe is sealing closed state, and the nozzle for having washed bladder pipe only is aperiodically to infuse at any time Enter processing solution to need in open state, be to prevent bacterium or urine into and out from the nozzle of washed bladder pipe when clinical, Now using manually with the method for husky cloth temporary plug.Nonetheless, due to bad sealing, still there is pipe of the bacterium from washed bladder pipe Mouthful entering infected patient bladder event occurs, and urine also often oozes out pollution environment from the nozzle of washed bladder pipe, when from flushing When the nozzle of bladder tube injects medical fluid into patient's bladder, the husky cloth of temporary plug need to be first taken out, this operation is more difficult, delay The state of an illness, and need to operate repeatedly, time-consuming and laborious, sealed sunitary condition.

Summary of the invention

The purpose of this utility model is to design a kind of catheter with washed bladder switch, has structure simple, design is closed Reason, saves labor, and fungi-proofing sanitary condition is good, easy to use, the at low cost and good advantage of using effect.

For this reason, the utility model is made of catheter, the open end of the washed bladder pipe of catheter is equipped with washed bladder Switch, the front cone cylinder body shape in a tubular form of washed bladder switch set guide card body in tubulose round estrade, the front end of guide card body to valve port Between tubulose round estrade in space form switch gear room, the middle part of guide card body is equipped with the through-hole for guide post slide fit, guide card body periphery It is located at water hole in spacing distance, is located in valve port in the valve plug of round estrade, one end of guide post is fixed in the middle part of the rear end of valve plug On, the other end of guide post passes through through-hole, spring is arranged on the guide post between the rear end and guide card body front end of valve plug, before valve plug End middle part sets press column, and the front end for pressing column is located at outside valve port.

The valve plug is made of rubber.The rear portion of the washed bladder switch is plugged in the open end of washed bladder pipe It is interior.

Said structure design has reached the purpose of this utility model.

The utility model has structure simple, and design rationally, saves labor, and fungi-proofing sanitary condition is good, easy to use, at This low and good advantage of using effect.The utility model washed bladder switchs opening and closing washed bladder pipe port, dispenses artificial With the method for husky cloth temporary plug, that is, manpower is saved, and health is fungi-proofing, and easy to operate rapid, there is good using effect.

Detailed description of the invention

Fig. 1 is the rear structure schematic diagram of the catheter of the utility model.

Fig. 2 is the structural schematic diagram that the washed bladder of the utility model switchs.

Specific embodiment

As shown in Figure 1 to Figure 2, a kind of catheter with washed bladder switch is made of catheter, and catheter 3 rushes The open end for washing bladder tube 2 is equipped with washed bladder switch 1.The front cone cylinder body shape in a tubular form of washed bladder switch.Tubulose rotary table Guide card body 10 is set in vivo, space forms switch gear room 7 in the front end to the tubulose round estrade between valve port 8 of guide card body.Guide card body Middle part is equipped with the through-hole for 9 slide fit of guide post, and guide card body periphery is located at water hole 6 in spacing distance.In valve plug 12 of round estrade In in valve port.On one end of guide post is fixed in the middle part of the rear end of valve plug, the other end of guide post passes through through-hole.The rear end of valve plug with lead Spring 11 is arranged on guide post between sheet body front end.The front center of valve plug sets press column 13, and the front end for pressing column is located at valve Outside mouthful.

The valve plug is made of rubber.The rear portion of the washed bladder switch is plugged in the open end of washed bladder pipe It is interior.

The front end of the catheter of the utility model is contact pin (for traditional structure, therefore omitting), the rear portion trident point of catheter Open form is at drainage tube 5, washed bladder pipe and closing charging pipe 4.Drainage tube holds urine bottle for leading to urine in patient's bladder In.Charging pipe is closed for positioning insertion pin head in patient's bladder.Washed bladder is effective to be injected into patient's bladder when necessary Processing solution.

When processing solution need to be injected into patient's bladder with washed bladder pipe, the processing solution communicated with medicinal liquid bottle is led Pipe sleeve is in the valve port outer end wall that washed bladder switchs, the press of the press mesh sheet press valve plug front end in processing solution conduit Column is retracted into switch gear room, and valve plug is opened, while the spring contraction on the rear end face press guide post of valve plug stores up power, due to guide post Rear end passes through through-hole, and guide post plays guiding valve plug.After valve plug is opened, the medical fluid in medicinal liquid bottle enters valve from processing solution conduit Mouthful, then flow successively through valve plug periphery, switch gear room, guide card body water hole after, then entered in patient's bladder by washed bladder pipe Inject processing solution.After flushing, only processing solution conduit, the press column of valve plug front end need to be pulled away from washed bladder switch Pressure is lost, the spring on guide post is upheld, and spring press valve plug recloses valve port, and washed bladder switch reseals closing punching Wash bladder pipe port.

In short, the utility model has structure simple, design rationally, saves labor, fungi-proofing sanitary condition is good, user Just, the at low cost and good advantage of using effect.
