Description

The introducing pipe joint structure of modularized combination type medical semi-automatic drainage metering device

Technical field

The utility model belongs to technical field of medical equipment, and in particular to a kind of modularized combination type medical semi-automatic drain The introducing pipe joint structure of metering device.

Background technique

Medical semi-automatic drainage metering device above-mentioned measures for urine of the medicinal to urethral catheterization patient and may be used also To the drain liquid metering of the postoperative patient of splanchnocoel, so that medical worker understands the pathological condition of patient and according to pathological condition Reasonably adjust medication and therapeutic scheme；It is above-mentioned introduce pipe fitting be set on drainage tube for by drainage tube be inserted in The intravesical catheter connection of urethral catheterization patient is connect with the drainage-fluid fairlead of the splanchnocoel of insertion splanchnocoel postoperative patient Transition member.

Previously, medicinal drainage generallys use drainage bag, and structure is by plastic tube (also known as drainage tube) and with large capacity The plastics liquid storing bags of Calibrated markings forms, this drainage bag due to cannot correctly measure and can only essence slightly estimate patient urine volume or Drainage-fluid liquid measure causes error big, affects to clinical monitoring quality, therefore gradually by superseded.

Then, it there has been the liquid meter reservoir similar to the structure type as disclosed in following documents.Such as: China " medical semi-automatic urine metering storing apparatus " that patent ZL02123886.3 is introduced " disposably may be used disclosed in ZL91225245.6 " the disposable essence of " electronic body fluid measuring instrument ", ZL94242826.9 announcement that metering plastics urinal ", ZL93224818.7 are related to " the row of " a kind of metering urine bottle ", ZL99209573.5 recommendation that really metering double-cavity urine drainage device ", ZL97211613.3 are provided Urinate recorder jar ", ZL00221285.4 disclose " patient urine discharge monitoring meter " and ZL01225226.3 and " a kind of urinal and urine meter of accurate measurement ", etc. that ZL01268645.X recommends respectively.

It is not limited to be short of jointly existing for patent formula exemplified above and be cured by invention Authorization Notice No. CN1282451C( With semi-automatic urine metering storing apparatus) it makes up, for details, reference can be made to the patent specification the 6th rows of page 1 to the inverse the 5th of page 3 Row.And defect existing for the CN1282451C is stored by Authorization Notice No. CN200994924Y(medical semi-automatic drain liquid metering Device) technical solution eliminated, for details, reference can be made to the specification of CN200994924Y final stages of page 4 to page 6 the 4th Row.In addition, CN202207340U(medical semi-automatic drainage metering device) it is lacked also for other existing for aforementioned CN1282451C Regret proposes improvement.

Above-mentioned CN1282451C, CN200994924Y and CN202207340U and including unmentioned above A kind of urine storing metering device of CN2778276Y() there is following shortcoming: first, hard due to being all made of unique one Matter box body, therefore urine storage capacity is limited, however, if easily causing manufacture and use cost to increase box body volume Increase, and raw material expends big, eventually leads to the medical expense that patient undertakes and increases；Second, since metering method is shown as As a result it measures, thus is difficult to embody the delicate metering effect that process is mutually helped with result, third, since the structure of box body bleeder valve has Lose rationally, therefore be easily damaged in finished product packing, transport and storage, once and bleeder valve cause damage to will lead to entire dress It sets and scraps；Puzzlement fourth, due to not having to the stochastical sampling function of drainage-fluid, thus when medical worker being caused to sample.

" the primary-secondary type medical half that the shortcoming of aforementioned four aspect is announced by invention patent mandate notification number CN103203044B Automatic jet metering device " is eliminated, and the CN103203044B has objectively fulfilled in the technical effect column of its specification The technical effect for five aspects recorded, but still remain following shortcoming: first, since only setting takes on introducing pipe fitting Sampling device (the 0034th and 0036 section of specification) and without gas-permeable, liquid-impermeable device, thus be unfavorable for making in drainage process introducing and manage Interior air outwardly releases；Second, due to the box body bleeder valve for the endoceliac liquid of the box of box body such as urine to be discharged It is made of valve seat, valve sleeve, screw-casing and spool, valve seat is fixed by the bottom wall of thermofussion welding mode and box body, valve sleeve insertion It is communicated in the valve support chamber of valve seat and with the box body chamber of box body, and the lower end of valve sleeve is stretched over outside the valve support chamber of valve seat, spiral Set is matched with the screw thread on the outer wall of valve sleeve lower end, and spool is integrally formed knot with the spiral mantle cavity of screw-casing by valve core case Structure when tapping, is held with finger and is pinched and turn screw-casing, spool is made to leave the closure to valve sleeve, otherwise same example, thus whether Tapping is also off tapping, and the operation to screw-casing is that very laboriously (for details, reference can be made to the patent specifications the 0030th To 0031 section)；Third, since the position of box body bleeder valve is located at box body bottom, and due to that finger need to be made to revolve when operation such as tapping Dynamic screw-casing, due also to the small volume of entire box body bleeder valve, thus the careless slightly hand that can pollute tapping person in tapping Refer to, especially when both the inner wall of screw-casing and the outer tube of valve sleeve are when being threadedly engaged not good enough, during tapping, liquid can be from The fit clearance infiltration of the two is let out, and dirty and tapping operator (the usually entourage of patient)；Fourth, due to being finished in tapping The abundant tightening state for being back to screw-casing with valve sleeve is needed afterwards, so that liquid outlet of the spool to valve sleeve sufficiently blocks, because And the degree that screws of both screw-casing and valve sleeve is determined with feel entirely, without same physical efficiency and different age group or even dissimilarity Other entourage is often different to the aforementioned perception for screwing degree and judgement, thus is difficult to during clinical use Avoid the endoceliac liquid of box improper situation for seeping drop from box body bleeder valve；Fifth, due to the structural system of device for hanging bag A pair of of hook be integrally formed structure with hanger plate, and hanger plate extends the connection strap implantation liquid storing bag of composition through its underpart Hanging bag is intracavitary, and due to also having a lanyard in the structural system of device for hanging bag, is existed according to field condition in actual use with benefit Flexible choice (referring specifically to the 0039th to 0040 section of the patent specification) between a pair of hook and lanyard, thus when selecting with hanging When rope hanging, a pair of hook can nearby generate interference effect to hanging not only at extra burden, in particular, because not It is careful will lead to liquid storing bag when hitting hook and shaken together with box body put, the delicate metering effect of delicate metering chamber is influenced, because aforementioned During shaking pendulum, the intracavitary liquid of delicate metering can abnormally flow into the large capacity measurement chamber of box body from demarcation plate overflow port It is interior；Sixth, due to only being hung in a state of use by being connected to the aforementioned device for hanging bag on liquid storing bag top, thus liquid storing bag connects It is opposite with the balance of box body to be short of, and the superiority and inferiority of balanced degree can equally have an impact metering effect.

For shortcoming existing for above-mentioned CN103203044B, it is necessary to then improve, for this purpose, the applicant made it is beneficial Design, forms technical solution described below finally.
