Description
Technical field
The invention belongs to technical field of medical instruments, especially relate to a kind of negative pressure o urethral catheterization device and urethral catheterization method.
Background technology
At present, some critically ill patients apply general anaesthetic Post operation or during hospitalization handicapped it is impossible to leave the bed from
Row urinate, at this time generally require urethral catheterization or cite approvingly urine device carry out aid urination, otherwise urine alluvial overlong time can lead to
Double hydronephrosis damage renal function.And if when running into the Urology Surgeries such as urinary system calculus, tumor, wound common hematuria symptom, blood
The high urine of urine concentration is deposited in intravesical and is formed clottage urinary tract, heavy then lead to acute renal failure threat to life, thus
For above-mentioned patient, reliable and effective urethral catheterization is most important for the treatment of patient, and traditional urethral catheterization mode is by catheter
Through per urethram inserting bladder, drain the process of urine, occurred in that in prior art using negative pressure mode urethral catheterization, improved effect
The mode of fruit, but current Clinical practice drainage tube quality is soft, and connecing negative pressure makes tube wall sunken it is impossible to effectively realize the effect of negative pressure often
Really, and existing negative pressure o urethral catheterization device is often required to use the devices such as vacuum pump, complex structure, operation is not easy, and cost is also relatively
High.
Content of the invention

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
A kind of negative pressure o urethral catheterization device, including negative pressure cylinder 1, catheter 2, evacuating catheter 3, the first check valve 4, the second check valve 5,
Pedal 6, push rod 7, push pedal 8, oil groove 9, the 3rd check valve 10, the first spring 11, orientation triangle block 12, second spring 13, positioning
Groove 14.
Described negative pressure cylinder bottom is conical cavity, and negative pressure cylinder is provided with catheter and evacuating catheter, and catheter height is higher than
Evacuating catheter, evacuating catheter is located at conical cavity bottom, and catheter is provided with the first check valve, and evacuating catheter is provided with the second check valve,
Negative pressure cylinder top is provided with pedal, pedal to connect and connects push pedal under push rod, push rod, and push pedal embeds oil groove, and push pedal lower surface is near negative pressure
It is provided with the 3rd check valve opening oil groove, the two ends of push pedal adopt tool flexible material springy such as gum elastic at cylinder inwall,
(the first back-moving spring is divided in push pedal, and (the first back-moving spring bottom connects circular cone cavity, and negative pressure cylinder inwall is provided with 3 highly differences
Orientation triangle block, there is inside described orientation triangle block corresponding locating slot, it is fixed that second back-moving spring two ends connect respectively
Position corner block and locating slot inwall, orientation triangle block can under push pedal effect retraction locating slot；Orientation triangle block is equipped with leads
Above urinary catheter,
It is provided with rigid casing, catheter, evacuating catheter bond with rigid casing respectively outside described catheter and evacuating catheter.
Catheter, when using, is connected bladder or the pudendum to patient, subsequently steps on pedal 6, pass through by the present invention first
Push rod promotes push pedal to move down, now the first closed check valve, and the second check valve is opened, and in cavity, gas is discharged, the 3rd check valve
Open, in oil groove, lubricating oil stays along oil groove, both made the lubrication between push pedal and negative pressure barrel, serve sealing prevents gas again
Body leakage effect, push pedal when moving down, the first spring-compressed, when push pedal moves down into first orientation triangle block, reach first
Level negative pressure value, now user have sensing, if do not need increase negative pressure value, unclamp pedal, pedal is in (the first back-moving spring
In the presence of upper move, if necessary to continue to increase negative pressure value, then continue lower pedal, orientation triangle block compression second spring enters
Locating slot, push pedal continues to move down, until reaching the 2nd, 3 orientation triangle blocks.
After unclamping pedal, push pedal (the first back-moving spring effect under on move, now first check valve open, the second check valve
Close, form negative pressure, the 3rd closed check valve in cavity, sealing lubricating oil no longer flows out, and Urine in Patients is under the suction of negative pressure
Enter cavity along catheter, and flow into conical cavity along cavity wall, after urethral catheterization terminates, again step on pedal, promoted by push rod
Push pedal moves down, now the first closed check valve, and the second check valve is opened, and the urine in cavity flows into after conical cavity along cavity wall
Discharged through the second check valve by evacuating catheter.
Present invention design is ingenious, by three one-way valve designs, pushes pedals twice, completes negative pressure formation, urethral catheterization, row
The function of urine, the first closed check valve when forming negative pressure, it is to avoid to patient's bladder or pudendum build-up of pressure, when urinating, first is unidirectional
Valve cuts out, and effectively prevent the misery that urine reflux back causes to patient, and the design of conical cavity makes urine discharge conveniently,
Avoid urine and accumulate in negative pressure cylinder, the design of three orientation triangle blocks, so that the space of compression is different in cavity, discharges gas
The scale of construction is also different, thus the negative pressure value being formed is also different, different patients can select different negative pressure value, has both avoided negative pressure
Power is too small, and to lead to draw urine effect bad, turn avoid that negative pressure is excessive to cause suffering to patient, and orientation triangle block is equipped with urethral catheterization
Above pipe, it is to avoid step on below catheter by push pedal, if the 3rd orientation triangle block still can not meet negative pressure value and require by mistake,
Unclamping pedal makes shifting, and now in catheter, gas enters inner chamber, continues to step on, gas is discharged, now bears after reaching top
Pressure value will be further increased.The design of the 3rd check valve makes push pedal, and movement has sealing lubricating oil to flow in negative pressure cylinder each time
The front end of wall push pedal, and move into formation oil film in push pedal and the gap of negative pressure cylinder inwall with push pedal, both can lubricate, keep away
Exempt from push pedal and the abrasion of inwall, played sealing again, prevent the effect of gas effusion.
Catheter, evacuating catheter bond with rigid casing respectively, it is to avoid it is sunken to connect tube wall during negative pressure, effectively achieves negative pressure
Effect.
The two ends of push pedal enter such as gum elastic using having flexible material springy, play good sealing and reduce friction
Effect.
The method that the negative pressure o urethral catheterization device of the present invention is carried out is also very simply it is only necessary to be connected to water pipe by catheter
Or bucket, repeat above-mentioned trample process twice, water can enter inside cavity cleaning cavity wall discharging.
In addition pedal not only can be stepped on foot, and can be positioned on bed with handss by the patient of convenient bed uses.
The above, be only presently preferred embodiments of the present invention, not the present invention imposed any restrictions, every according to the present invention
Any simple modification, change and equivalent structure change that technical spirit is made to above example, all still fall within skill of the present invention
In the protection domain of art scheme.
