Description

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 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.

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or Drainage-fluid liquid measure causes error big, affects to clinical monitoring quality, therefore gradually by superseded.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, due to for the box of box body is endoceliac Liquid for example urine discharge box body bleeder valve be made of valve seat, valve sleeve, screw-casing and spool, valve seat by thermofussion welding mode with The bottom wall of box body is fixed, and is communicated in the valve support chamber of valve sleeve insertion valve seat and with the box body chamber of box body, and the lower end of valve sleeve Be stretched over outside the valve support chamber of valve seat, screw-casing is matched with the screw thread on the outer wall of valve sleeve lower end, spool by valve core case with The spiral mantle cavity of screw-casing is integrally formed structure, when tapping, is held and is pinched and turn screw-casing with finger, leave spool to valve sleeve Closure, otherwise same example, thus whether tapping is also off tapping, and the operation to screw-casing is very laboriously (specific It can be found in the 0030th to 0031 section of the patent specification)；Second, the position due to box body bleeder valve is located at box body bottom, again Since finger turn screw-casing need to be made when operation such as tapping, due also to the small volume of entire box body bleeder valve, thus in tapping When the careless slightly finger that can pollute tapping person, especially when being threadedly engaged for both the inner wall of screw-casing and the outer tube of valve sleeve is deficient When good, during tapping, liquid can be seeped from the fit clearance of the two be let out, and (usually patient accompanies by dirty and tapping operator Shield personnel)；Third, due to the abundant tightening state for needing to be back to screw-casing with valve sleeve after tapping, so as to spool The liquid outlet of valve sleeve is sufficiently blocked, thus the degree that screws of both screw-casing and valve sleeve is determined with feel entirely, and it is different The entourage of physical efficiency and different age group or even different sexes to the aforementioned perception for screwing degree and judgement often it is each not It is identical, thus the endoceliac liquid of box improper feelings for seeping drop at box body bleeder valve are difficult to avoid that during clinical use Shape；Fourth, since a pair of of hook of the structural system of device for hanging bag is integrally formed structure with hanger plate, and hanger plate passes through under it The hanging bag that portion extends the connection strap implantation liquid storing bag constituted is intracavitary, and due to also having one to hang in the structural system of device for hanging bag Rope, with benefit in actual use according to field condition a pair of hook lanyard between flexible choice (referring specifically to saying for the patent The 0039th to 0040 section of bright book), thus when select hung with lanyard when, a pair of hook is not only at extra burden, but also meeting Interference effect nearby being generated to hanging, in particular, shaking pendulum together with box body because will lead to liquid storing bag when hitting hook accidentally, influencing precision The delicate metering effect of measurement chamber, because the intracavitary liquid of delicate metering can be abnormally from separation during aforementioned rolling pendulum Plate overflow port flows into the large capacity measurement chamber of box body；Fifth, due in a state of use only by being connected to liquid storing bag top The hanging of aforementioned device for hanging bag, thus liquid storing bag together with box body balance it is opposite be short of, and the superiority and inferiority of balanced degree equally can Metering effect is had an impact.

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.
