Abstract
The utility model discloses a liquid drainage valve capable of being fixed in an inserted-connection mode. The liquid drainage valve capable of being fixed in the inserted-connection mode comprises a one-way inserted-connection protrusion (1) which surrounds a valve shell and a switch handle (2). The liquid drainage valve capable of being fixed in the inserted-connection mode is characterized in that a segment which is perpendicular to the axis of the one-way inserted-connection protrusion (1) is arranged in the one-way inserted-connection protrusion (1) segment, wherein the outer edge of the cross section of the segment is not circular. The liquid drainage valve capable of being fixed in the inserted-connection mode is convenient to operate, saves effort, avoids cross contamination and is simple in structure and manufacturing technology. After the liquid drainage valve capable of being fixed in the inserted-connection mode is connected with a liquid storage bag in an inserted mode, rotation and disengagement of the liquid drainage valve can be effectively limited.

Technical field
This utility model relates to medical instruments field, relates in particular to a kind of fixing tapping valve of pegging graft.
Background technology
The tapping valve of existing liquid storing bag mainly contains cross valve, roll-over valve etc., and they are provided with unidirectional grafting projection, and the passable grafting pipeline grafting with on the liquid storage bag is assembled, and we find that in producing and using its shortcoming is:
The first, as shown in Figure 3, the unidirectional grafting projection of the tapping valve cross section outer rim vertical with unidirectional grafting projection axle center all is circular, although can seal and limit the effect that tapping valve breaks away from liquid storing bag, but because the vertical cross section outer rim in unidirectional grafting projection axle center is circular configuration, tapping valve is easy to around the axle center rotate, and particularly tapping valve often occurs in transportation, operating process and the rotational displacement situation occurs, the impact operation, need manual setting, trouble is bothersome; If bonding with glue, because the volatilization of organic solvent, abnormal smells from the patient is heavy, brings certain harm for operator's health, and possibility shutoff pipeline in the bonding process, waste product occurs.
The second, there is not fixing switch handle, majority needs bimanualness, in conventional the use, often need to be put on the other hand on the adjacent draining valve of leakage fluid dram and fix, and console switch is opened on the other hand.Like this operation, liquid storing bag rocks easily, needs simultaneously collaborative having an effect of two handss, operates cumbersomely, and two hand operateds have also increased the chance that touches with leakage fluid dram, and particularly fixedly hands false touch leakage fluid dram chance is larger, causes cross-contamination.
The 3rd is the operation effort, although main cause is that the arm of force of swing handle is long, but because tapping valve does not have special-purpose fixed position, often need a hand-held tapping valve body of holding, keep tapping valve relatively static, counteracting force when resisting simultaneously another hands and opening or close in the practical operation, and does not think laborsaving; The tapping valve of existing one-hand operation need to directly overcome the frictional force that promotes spool, also relatively requires great effort.
The applicant has done corresponding retrieval for the prior art of stipulating in the patent regulation, retrieve immediate prior art and be patent name that Jiang Sukang advances the application of medical device company limited and be the utility model patent with the liquid storing bag of through hole cross valve, the application number of above patent is: 201120258779.9, the applying date is: 2011.07.21, Granted publication number are: CN202191517U.The utility model that the independent claims of above prior art need protection is created point: a kind of liquid storing bag with the through hole cross valve; comprise bag; feed liquor conduit and cross valve; cross valve is by valve body; transverse pipe and slide bar form; the length of slide bar is greater than transverse pipe; valve body is with the transverse pipe cross and be connected; one end of valve body is provided with inlet; the other end is provided with liquid outlet; the inner chamber of transverse pipe is communicated with inlet and liquid outlet respectively; slide bar and transverse pipe are pegged graft; and the cylindrical of junction surface slide bar matches with the inwall of transverse pipe; it is characterized in that: slide bar is provided with manhole, and when slide bar is pushed an end to, manhole and inlet and liquid outlet staggered positions; when slide bar was pushed the other end to, manhole and inlet and liquid outlet were connected simultaneously.The purpose of above prior art is: a kind of convenient liquid storing bag with the through hole cross valve that uses, also can avoid clogging is provided.
The applicant is at a kind of drainage bag tapping valve utility model patent of front declaring, application number: 201210374473.9, and the applying date is: 2011.09.28, Granted publication number are: CN202876087U.The utility model that the independent claims of above-mentioned prior art need protection is created point: a kind of drainage bag tapping valve, and it comprises the leakage fluid dram of valve casing and below; It is characterized in that: the valve casing sidewall is provided with the inlet that leads to valve casing inside; The switch touch control part connects the closure member of bottom by drive mechanism.The purpose of above prior art is: a kind of easy to operate drainage bag tapping valve is provided, avoids operator, user owing to the tapping valve improper use causes cross infection.Immediate prior art is created the identical or similar utility model that does not belong to mentioned in the patent examination guide with this utility model and is created.
Summary of the invention
For the problem that exists in the background technology, the purpose of this utility model provide a kind of easy to operate, avoid cross-contamination, simple in structure, a kind of and liquid storing bag that manufacturing process is easy to peg graft after effective restriction tapping valve a kind of fixing tapping valve of pegging graft of rotating, coming off.
For realizing above purpose, the technical solution adopted in the utility model is: a kind of fixing tapping valve of pegging graft, comprise unidirectional grafting projection, switch handle around valve casing, it is characterized in that: it is non-circular section that the cross section outer rim vertical with unidirectional grafting projection axle center arranged in unidirectional grafting projection section.
Above-mentioned " unidirectional grafting projection " refers to that the grafting pipeline of tapping valve and liquid storing bag is pegged graft when assembling, and the longitudinal section that insert easily pipeline, is difficult for withdrawing from is trapezoidal structure.
Above-mentioned " unidirectional grafting projection section " refers to be higher than between the axial area of unidirectional grafting projection of tapping valve case surface, and above-mentioned " section " is the part of " section ".
Under more excellent enforcement state, described cross section outer rim is ellipse or polygon.
" limit " in above-mentioned " polygon " is straight line or curve or both combinations.
Under more excellent enforcement state, described switch handle comprises fixed handle and swing handle.
Above-mentioned " fixed handle " refers to when the opening and closing tapping valve, with respect to the fixed handle of tapping valve.
Under more excellent enforcement state, described switch handle is positioned at the tapping valve upper end.
The beneficial effects of the utility model: production technology is easy, directly peg graft with the grafting pipeline of liquid storing bag, just can effectively connect, spacingly fix and seal; Because fixed handle is set, leaving leakage fluid dram has certain distance, avoids cross-contamination; Because the existence of fixed handle and swing handle, can exert oneself simultaneously in both sides, and rapid operation is steady.
