Description
technical field:
This utility model relates to a kind of o urethral catheterization device, belongs to medical product technical field.
background technology:
At present within the hospital, patient for dysuric patient and long-time needs operation all needs to use catheter to help patient urinates, o urethral catheterization device of the prior art is mostly by catheter, urinal urine collector is formed, when Medical Technicians carries out urethral catheterization intubation to patient, first be that urethra is stretched in catheter end, then adhesive plaster bonding is around in catheter, glued on the external genitalia with patient again, urine is Natural excrement from catheter, but in this process, just there is a lot of problem and operating defect, as not easily intubate, due to the existence of catheter pipe shaft self friction power, great misery is brought to patient in catheterization procedure, corresponding psychological shade is brought to patient, after intubate, catheter is not easily fixed, easily surprisingly skid off from urethra, operation inconvenience is brought to medical operator, misery is brought to patient, simultaneously, in this process, easily cause the superinfection of catheter, cause the damage of urethral mucosa, meanwhile, when immobilization with adhesive tape, due to the existence of people self perspiration or other body fluid, can cause being pasted not strongly, easily loosen, and there is most patient corresponding in the whole process of rubberized fabric adhere, easily cause skin allergy etc. problem, more existing products can fix catheter to reach the object of some improvement by button bit, catheter is pasted and is fixed on skin by the application of dressings also having some products to pass through research and development and skin-compatible, but above-mentioned technological improvement all exists, structure is too complicated, production cost is too high, troublesome poeration, and do not reach the drawbacks such as desired effect.
utility model content:
In order to overcome the many drawbacks existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of convenient insertion, and after intubate, catheter can be fixed spacing, prevent its unexpected o urethral catheterization device skidded off from urethra, its structure is simple, easy to operate, practical function, is convenient to the marketization.
The technical scheme that this utility model adopts to achieve these goals is as follows:
A kind of o urethral catheterization device, comprise urinal and catheter, it is characterized in that: on urinal opening, be provided with spacing non-return mechanism, described spacing non-return mechanism inside is provided with hollow connecting pipe, its opening being positioned at urinal inside is provided with flake structure, arrange through hole at flake structure center, through-hole diameter is less than the external diameter of catheter, and catheter is movably installed on spacing non-return mechanism.By arranging the through hole more smaller than the catheter external diameter matched at flake structure center, through hole and catheter is made to form slight Interference contact, the concrete magnitude of interference is between the scope of 0.15mm to 0.20mm, during operation, because through-hole structure is less than catheter external diameter, when catheter stretches out, with flake structure Interference contact, in catheter moving process, the trend of the Direction distortion of flake structure oriented catheter movement can be made or slight stretch out Direction distortion to catheter, now, there is deformation tendency or have the flake structure of slight deformation, counteracting force can be formed to catheter, limit catheter to move backward, a spacing non-return effect is played to catheter, effectively prevent catheter back to slide.
This utility model is set to further:
Being separated by between flake structure certain even distance, is linear contact lay or point cantact with catheter pipe shaft, and the jag of flake structure forms circular.
Preferably, described flake structure is circular shape, and the jag of flake structure can be linear contact lay with catheter pipe shaft.
Described flake structure is triangle, and the jag of flake structure can be point cantact with catheter pipe shaft.
Described spacing non-return mechanism can be arranged on urinal opening by the mode of welding.
Described welding manner is sweat soldering or heat seal welding, and welding position arranges reinforcement; By arranging corresponding muscle position to the position that urinal carries out welding, add the contact area of spacing non-return mechanism and urinal, being convenient to spacing non-return mechanism can be weldingly fixed on urinal more firmly.
Described urinal is the transparent membrane urinal of band urine volume scale, and its urine to derive more more convenient than common urinal carries out the observation of the character such as color, amount of urine.
The opening being positioned at urinal outside at spacing non-return mechanism is set with silica gel connector, in position, silica gel connector top end opening hole or cross cutter spacing gap, is convenient to catheter and stretches out, also serve certain fixation simultaneously; Silica gel connector is movably installed with medicated cap.
In urinal, apply one deck hydrodynamic lubrication material, this hydrodynamic lubrication material has good biocompatibility.By applying one deck hydrodynamic lubrication material at urinal inner homogeneous, because catheter is arranged at urinal inside, when catheter stretches out along spacing non-return mechanism from urinal, catheter pipe shaft applies one deck greasing substance, reduce the frictional force of catheter pipe shaft, effectively can alleviate the misery of patient in catheterization procedure, facilitate the operation of medical worker.
The beneficial effects of the utility model:
1, this utility model structure is simple, by arranging spacing non-return mechanism at urinal mouth, at the flake structure center of spacing non-return mechanism, the through hole more smaller than the catheter external diameter matching suitable is set, through hole and catheter is made to form slight Interference contact, during operation, because through-hole structure is less than catheter external diameter, when catheter stretches out, with flake structure Interference contact, in catheter moving process, the trend of the Direction distortion of flake structure oriented catheter movement can be made or slight stretch out Direction distortion to catheter, now, there is deformation tendency or have the flake structure of slight deformation, counteracting force can be formed to catheter, limit catheter to move backward, a spacing non-return effect is played to catheter, effectively prevent catheter back to slide.Catheter effectively can be avoided in indwelling catheter process surprisingly to skid off urethra, decrease the nursing work load of medical worker, also alleviate the psychological burden of patient to a great extent;
2, easy to operate, by urinal internal coat one deck hydrodynamic lubrication material, decrease the size of catheter pipe shaft frictional force, effectively alleviate the misery of patient in catheterization procedure; Meanwhile, due in operating process, all do not need Medical Technicians to touch catheter, all drawbacks that medical cross infection and secondary pollution bring can be efficiently avoid.
Below in conjunction with the drawings and specific embodiments, this utility model is further described, be intended to help relevant those skilled in the art to understand content of the present utility model better, but protection domain of the present utility model is not limited thereto.
