Description
Technical field
This utility model relates to a kind of catheter threshold pressure switching device with safety valve function and exercise bladder capacity function, belongs to technical field of medical equipment.
Background technology
Clinically, for medium-term and long-term urethral catheterization patient, be protection wall of urinary bladder baroreflex, prevent bladder capacity atrophy gradually, in nursing, often need timing alternation switch catheter valve.The workload of the nursing staff that this operation increases greatly, and quantitative management cannot be accomplished for intravesical pressure, the effect of protection bladder function is also more weak.
In addition, for loss of consciousness or paralytic patient, because it can not the autonomous urine meaning that formed by wall of urinary bladder pressure receptor of perception, and bladder excessive expands inducible pain, once forget for a long time and open urinary catheter switch in nursing, very easily cause bladder excessive to expand, the lighter damages wall of urinary bladder function, and serious even has the risk causing rupture of bladder.
For solving this problem, the people such as Sun Yong devise " a kind of catheter pressure switch apparatus of tempering patient urinates ability " (application number: CN201410556147), adjustable pressure switch apparatus is introduced in this design, first can preset a critical pressure, when patient has urine meaning, initiatively start micturition reflex by patient conscious, shrink bladder, improve intravesical pressure, when intravesical pressure triggers catheter valve higher than during the critical pressure preset, thus get rid of urine.This design to some extent solves the problem of tempering bladder function.
The design of the people such as Sun Yong is mainly for the training of the critical state of urinating of bladder, the i.e. contractile function of detrusor of bladder, when urine portion is discharged, when bladder capacity declines, intravesical pressure can reduce rapidly, now rely on merely detrusor of bladder also cannot maintain intravesical pressure, the pressure switch of therefore its design can be closed rapidly, and now intravesical major part urine is not yet discharged.Should say that its design is a device of well tempering detrusor of bladder function, but be not " a threshold pressure switch " truly.
In addition, inapplicable for loss of consciousness or paralytic patient for this design, because it does not possess the ability producing urine meaning and initiatively start micturition reflex, detrusor of bladder function cannot be tempered.When pressure switch is closed, intravesical major part urine is not yet discharged, and can not reach the effect of discharging urine.

detailed description of the invention:
As Figure 1-4, this detailed description of the invention is by the following technical solutions: it comprises catheter body 1, catheter local interface A, first sliding shoe B, the second sliding shoe D, 3rd sliding shoe I, first elastomeric spring C, second elastomeric spring E, 3rd elastomeric spring J, first lightweight stiff rod F, rotating fulcrum G, chock H, passage K, catheter remote interface L, manual embolus M and attachment device i, catheter body 1 is provided with catheter local interface A and catheter remote interface L, the first sliding shoe B is provided with in catheter local interface A, one end of first sliding shoe B contacts with one end of the first elastomeric spring C, the other end of the first elastomeric spring C contacts with attachment device i, the below of the first sliding shoe B contacts with the upper end of the second sliding shoe D, the lower end of the second sliding shoe D contacts with the upper end of the second elastomeric spring E, and the lower end of the second sliding shoe D contacts with one end of the first lightweight stiff rod F, the middle part of the first lightweight stiff rod F is provided with rotating fulcrum G, the other end of the first lightweight stiff rod F is arranged on the top of chock H, the below of chock H is embedded in the draw-in groove above the 3rd sliding shoe I, 3rd sliding shoe I is provided with passage K, one end of 3rd sliding shoe I contacts with the 3rd elastomeric spring J, and the other end of the 3rd sliding shoe I contacts with manual embolus M, it is inner that 3rd sliding shoe I is arranged on catheter remote interface L.
As preferably, described attachment device i comprises the second lightweight stiff rod P, the first disk N, the second disk O, bolt Q with a scale and nut R, connected by the second lightweight stiff rod P between first disk N and the second disk O, and the middle part of the first disk N, the second disk O is interted and is provided with bolt Q with a scale, and bolt Q with a scale is provided with nut R.
The operation principle of this detailed description of the invention is: when urine through catheter local interface A enter and filling device after, under the effect of pressure, promote the first sliding shoe B and compress the first elastomeric spring C, the degree that first elastomeric spring C compresses can reflect the power of pressure, along with the increase of intravesical urine, pressure increases gradually, and the displacement of the first sliding shoe B also increases gradually; The slip of the first sliding shoe B can promote the second sliding shoe D and move, and the second elastomeric spring E is the resistance spring of the second sliding shoe D movement, and the movement of the second sliding shoe D can drive the first lightweight stiff rod F with rotating fulcrum G for fulcrum drives chock H to move; 3rd sliding shoe I is stuck in closed position by chock H, after chock H removes, 3rd sliding shoe I ejects under the effect of the 3rd elastomeric spring J, now, passage K on 3rd sliding shoe I and device inner chamber UNICOM, urinary catheter switch open, urine starts to flow out through catheter remote interface L, device from closed condition, enter starting state; Along with urine flows into catheter flowing out from intravesical, urethral catheterization intraductal pressure is less than intravesical pressure, now the first sliding shoe B sets back gradually under the effect of the first elastomeric spring C, and then the second sliding shoe D, chock H set back, but the 3rd sliding shoe I is still in enable possition, and this timer is in open state; 3rd sliding shoe I can promote manual embolus M when opening ejection and eject, and when manually promoting manual embolus M and compressing the 3rd elastomeric spring J, the draw-in groove on the 3rd sliding shoe I can be blocked by chock H, thus recovery device closed condition.
The reduction length of the first elastomeric spring C determines the sliding distance of the first sliding shoe B, thus finally determine device and whether open, the effect of attachment device i is the reduction length of adjustment first elastomeric spring C, first disk N is connected by the second lightweight stiff rod P with the second disk O, the device that formation can freely be slided in device wall and bolt Q with a scale, first elastomeric spring C is compressed rear promotion first disk N, second disk O and the second lightweight stiff rod P moves, nut R can fixed position thus restriction the first disk N, the movement of the second disk O and the second lightweight stiff rod P, when diverse location is fixed in nut R rotation, namely the compression degree of the first elastomeric spring C is determined, thus have impact on the sliding distance of the first sliding shoe B, finally determine device when to open, relation according to nut R and urethral catheterization intraductal pressure can mark scale on nut Q.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
