Description
Technical field
The invention belongs to technical field of medical equipment, be specifically related to a kind of tapping valve structure of urine drainage bag.
Background technology
Aforesaid urine drainage bag also can be described as urinary bag, patient's urethral catheterization of can not taking care of oneself for urinating in medicinal or home care uses, the urine derived by patient's intravesical by catheter imports in urine drainage bag, opens supporting tapping valve on urine drainage bag and urine in urine drainage bag got rid of after the full liquid of urine drainage bag.Aforesaid tapping valve also claims bleeder valve.
Technical information about urine drainage bag can be seen in disclosed Chinese patent literature, as CN201101619Y(reversed flow preventing urine collecting bag), CN2721101Y(flow controllable urine collected bag), CN201492789U(filter-type urine collection bag), CN203220624U(Novel urine collecting bag) and CN203861243U(coordinate urine metering instrument use urine drainage bag), etc.These patented technology contents from being not limited to exemplify: no matter the concrete structure of urine drainage bag, shape, material etc. occur how to change, but be not equipped with tapping valve at middle position, the bottom place of urine drainage bag exceptionally.
Consider from thrifty angle, the tapping valve be provided on urine drainage bag comprised in the prior art of the patent exemplified above can repeat to open and close, specifically, when after the full liquid of urine drainage bag, open tapping valve by medical worker or patient entourage urine drainage bag is emptying, then close tapping valve continuation collection urine.But, consider from the angle of medical safe and sanitary, urine drainage bag reuse the anxiety that safe and sanitary is lost in existence, infection is caused because the antibacterial in bag very likely attacks patient, typical in urinary tract infection, and can because of urinary tract infection cause do not wish to occur but be difficult to the complication avoided, this type of example is not rarely seen on medicinal.
In disclosed Chinese patent literature, the tapping valve structure about urine drainage bag can be seen in equally, as Authorization Notice No. CN201091743Y recommendation has " water-spreading bag liquid valve ", although this patent formula can embody the technique effect that its description page 1 last 1 walks to page 2 the 7th row, but it is can be reusable due to this water-spreading bag liquid valve structures shape, specifically can see the Instructions Page 2 final stage of this patent (explicitly pointing out: " unlatching or the closedown of valve can be realized "), thus there is the applicant in the above mentioned problem losing safe and sanitary.
And for example Authorization Notice No. CN201299902Y " disposable medical drainage bag, the urinal rotating bleeder valve " that provide, disposable concept alleged by this patent formula is aimed in fact same patient and uses, different patients can not being diverted to, repeating to open and close from understanding its valve known to the full text of this patent; For another example application for a patent for invention publication No. CN10308302A discloses " medical liquid discharge valve ", the achievement of this patent application scheme is easy to operate (one-hand operation), but from its overall structure, be can be reusable, thus there is the aforesaid drawback losing safety and sanitation in these two patent formula equally.
Certainly, be equipped with not reproducible use and irreversible tapping valve structure to urine drainage bag can significantly reduce and even stop to cause the factors such as patient's urinary tract infection, although medical expense that patient bears slightly can be increased to a certain extent and increase the consumption of resource, but from people-oriented and the theory of patient safety first is considered, the latter obviously overweights the former.
Seem to there is not any technology barrier for designing the tapping valve structure that unlatching can not be closed again only theoretically, specifically, when urine drainage bag is in the process of collection urine, tapping valve has been in the closed condition of designed when being manufactured by medical device production firm (also can claim to arrange), and after urine drainage bag is expired liquid and opened tapping valve eliminating urine, just tapping valve can not be returned to the state of again closing, just urine drainage bag cannot be made in this condition again to reuse, old cloth can only be abandoned new, to meet an enforceable instructions for use.But, because medical device manufacturer is difficult to avoid the spool of tapping valve to occur the situation of improper movement in the valve pocket of valve body in the link of producing, pack and transporting, storing and so on, thus once spool moves to opening in the chamber valve of valve body, whole urine drainage bag so will be caused to use, produce the wasting of resources.Especially as the industry's knowledge of the reason, valve pocket (the i.e. valve body chamber of spool and valve body, as follows) necessarily movably coordinate, so because rigging error and the natural cause of to expand with heat and contract with cold etc. cannot be avoided, thus spool becomes because of mobile and cannot get rid of the probability of the opening in valve body chamber in aforesaid links.From and caused the design difficulty how making to be in closed condition the link of spool beyond non-discharge opeing all the time, to this disclosed China and foreign countries' patent and non-patent literature all enlighten without referential technology through looking into up to now.
For above-mentioned prior art, the applicant has done positive and useful design, finally define technical scheme described below, and carried out the simulation test of non-limited number of times in the test center of the applicant taking under secrecy provision, result proves practicable.
