The invention relates to a medical transfusion switch, which belongs to the technical field of medical equipment and comprises a switch body and a poking handle, wherein the switch body comprises a switch sleeve, a liquid inlet joint and a liquid outlet joint, the switch sleeve is provided with a cavity, the cavity is provided with a liquid inlet hole and a liquid outlet hole, the liquid inlet joint is directly formed on the switch sleeve and is corresponding to the liquid inlet hole, the liquid outlet joint is directly formed on the switch sleeve and is corresponding to the liquid outlet hole, the poking handle is matched with the switch sleeve in a rotating mode, and the poking handle is provided with an arc-shaped sealing plate. The medical transfusion switch is characterized in that an arc-shaped supporting plate is arranged in the cavity and in the position corresponding to the liquid inlet hole, the arc-shaped supporting plate is formed on the bottom plate of the cavity, a sealing plate rotating groove is maintained above the arc-shaped supporting plate, the arc-shaped sealing plate is matched with the sealing plate rotating groove, a central line of the liquid inlet joint and an axial central line of the cavity are not in the same plane, one side of the poking handle, which faces the switch sleeve, is provided with a poking handle pivoting groove, and the poking handle pivoting groove is matched with the switch sleeve.
Description
Technical field
The invention belongs to the medical devices technical field, be specifically related to a kind of medical infusion switch
Background technology
such as industry the reason of knowledge, transfuse switch on infusion pipeline, is equipped with usually, the structure of transfuse switch roughly has two kinds: the one, pushing block or pinch roller formula structure, this switch autokinetic phenomenon occurs easily under slightly touching; The 2nd, what have 90 ° of angles of revolution dials the wushu transfuse switch; This transfuse switch can not occur changing because of slightly touching; But in the use of reality, still expose shortcoming, especially at night, patient self or entourage fail switch dialled and go to 90 °; The just disconnected liquid of tube for transfusion so, promptly obstructed liquid.Again, for example prolonged illness bed person, people with disability or the like often are difficult to the degree of dialling switching to 90 correctly ° owing to be short of physical strength for the weakling.
On
mirror, be necessary the structure of the transfuse switch of dialling wushu in the prior art is improved, for this reason, the applicant has done literature search, but in disclosed patent and non-patent literature, all is not seen in referential teachings.Yet the applicant has done repeatedly and good try has found the way of dealing with problems, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is to provide a kind of and helps to enlarge markedly an angle of revolution of dialling and use the convenient commentaries on classics and the medical infusion switch smoothly of guaranteeing to infuse dialled of the weak patient of donor.
task of the present invention is accomplished like this, and a kind of medical infusion switch comprises a Switch main body and group handle that matches with Switch main body; Described Switch main body comprises switch cover, liquid inlet joint and fluid joint; The switch cover has a cavity volume, on cavity volume, offers an inlet opening and a liquid outlet, and liquid inlet joint is formed in directly that switch puts and is corresponding with inlet opening; The fluid joint is formed in equally directly that switch puts and is corresponding with liquid outlet; Dial being rotatably assorted, and this group handle has one and is used for said inlet opening sealing or the arc sealing plate opened are characterised in that: in described cavity volume and at the position corresponding to inlet opening, one arc pallet is arranged with the switch cover; This plate shape supporting plate is formed on the cavity volume base plate of cavity volume; Above arc pallet, maintain a sealing plate swivelling chute, described arc sealing plate matches with the sealing plate swivelling chute, and the centrage of described liquid inlet joint and the longitudinal center line of said cavity volume are not at grade; Described group of handle offers one group the pivot groove towards a side of switch cover, and this group matched the pivot groove with the switch cover.
of the present invention group of notch position the pivot groove constitutes a spacing bead, and described switch cover constitutes a spacing bead groove on the outer wall of an end of said group of handle, and said spacing bead matches with this spacing bead groove.
technical scheme provided by the invention is by dialling the unlatching that realizes the unspecified angle of inlet opening in 180 ° of scopes, thereby the oneself that can satisfy the weakling operates requirement, guarantees that transfusion carries out smoothly.
Description of drawings
Fig. 1 is embodiments of the invention and application examples structure chart.
The specific embodiment
please be referring to Fig. 1; Provided a Switch main body 1; This Switch main body 1 is made up of switch cover 11, liquid inlet joint 12 and fluid joint 12; On the cavity volume 111 of switch cover 11, offer an inlet opening 1111 and a liquid outlet 1112, liquid inlet and outlet hole 1111,1112 is apart 180 ° of the circumferencial direction of switch cover 11, and liquid inlet joint 12 extends directly that switch overlaps on 11 and be corresponding with aforesaid inlet opening 1111; Fluid joint 13 equally directly is formed on the switch cover 11, and corresponding with aforesaid liquid outlet 1112.On the cavity volume base plate 1114 of cavity volume 111, constitute an arc pallet 1113; This arc pallet 1113 is corresponding to the position of inlet opening 1111; Maintaining spacer above the arc pallet 1113 and between the wall body of cavity volume 111, using by this spacing and constitute sealing plate swivelling chute 1115.On dialling, constitute the spacing bead groove 112 that one ring leads at switch cover 11 the outer wall of an end of 2.
There are skew in
centrage of aforesaid liquid inlet joint 12 and the centrage of cavity volume 111, promptly not at grade.
Dial
has an arc sealing plate 21 to 2, when dial 2 with switch overlap 11 match after, arc sealing plate 21 just matches with aforesaid arc pallet 1113, that is, this arc sealing plate 21 matches with sealing plate swivelling chute 1115.Be able to 2 overlap 11 good fit and ensure dial in order to make to dial 2 pivots with switch; Therefore on dialling, constitute one group pivot groove 22 2; And constitute one to the notch position of pivot groove 22 and be limited in bead 221 dialling; When the wall body of the right-hand member of switch cover 11 insert dial pivot groove 22 in the time, spacing bead 221 matches with aforesaid spacing bead groove 112 just.
can be known by above-mentioned explanation; Can in 180 ° scope, rotate owing to dial 2; Therefore also can guarantee transfusion even rotate small angle, and for example be in opening to 2, seal even the also unlikely so that inlet opening 1111 of situation occurs touching when dialling.The transfusion bag of illustrating among the figure 3 is used for connecting with liquid inlet joint 12
