Object of the present invention is achieved by the following technical programs:
A kind of bone cement mixer provided by the invention, comprises stirred vessel, upper cover, rocker arm, handle, shaft coupling, support member, fixed gear, moving gear, stirring vane; Described handle is arranged on the operating side of rocker arm, and the link of described rocker arm is positioned at and covers; Described shaft coupling has the connector stretching laterally and is down " T " font in its lower end, described shaft coupling is being arranged on the middle part in upper cover and being connected with the link of rocker arm through its upper end around the mode of its central shaft rotation; Described support member is fixed in upper cover and is set in the outside of shaft coupling; Described fixed gear and shaft coupling coaxially arrange and be set on support member and be positioned at its connector of shaft coupling above; Described moving gear be positioned at connector above and mesh with fixed gear; Described stirring vane be positioned at stirred vessel, connector below, and by its upper end being connected with moving gear around the mode of its central shaft rotation.
Bone cement mixer of the present invention, stirring vane is connected in the connector place of shaft coupling lower end and is and is eccentrically set in stirred vessel, by shaking rocker arm, shaft coupling is rotated around its central shaft, and then drive stirring vane around shaft coupling axis (being also stirred vessel central axis), to be circumferential revolution motion in container; Meanwhile, through the engagement of moving gear and fixed gear, stirring vane carries out spinning motion in above-mentioned revolution motion, thereby realizes omnibearing stirring.
For further reducing distributing of irritative gas, between stirred vessel of the present invention and upper cover, be provided with sealing ring.
In such scheme, on of the present invention, cover and be provided with steam vent, by this steam vent, through connection tube, be connected with negtive-pressure implement with filter, with the bubble producing in emptying whipping process, the gas sucking-off of penetrating odor is drained simultaneously, thereby effectively avoid the impact of irritative gas.
The present invention has following beneficial effect:
(1) stirring vane of the present invention had both been circumferential revolution motion in stirred vessel, meanwhile also had rotation function, thereby can be comprehensive, without ground, the dead angle bone cement that thoroughly stirs, use effect and the life-span of having guaranteed bone cement application.
(2) drive mechanism of the present invention utilizes lever principle to coordinate by shaft coupling, big or small external gear revolution and the rotation that realizes stirring vane, has both improved applicable velocity of rotation, has reduced again shared spatial volume.Compactness rational in infrastructure, is convenient to manufacture and install, and stable operation, laborsaving convenience, improved service efficiency.
(3) connector of its lower end of shaft coupling of the present invention, both be convenient to the assembling of fixed gear, moving gear and stirring vane, there is baffle effect simultaneously, can intercept bone cement because stirring the granule diffusion causing, thereby reduce infringement and the loss that bone cement floating particle brings.
(4) the present invention has good sealing property, can utilize vacuum suction to form vacuum environment, the bubble that emptying bone cement and adhesive whipping process produce effectively, use effect and the life-span of having guaranteed bone cement application; Meanwhile, can effectively get rid of penetrating odor gas, thereby intercept distributing of gas, avoid the impact on medical personnel's health and medical procedures in use procedure.
Accompanying drawing explanation
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail:
Fig. 1 is the profile schematic diagram of the embodiment of the present invention;
Fig. 2 is structural representation embodiment illustrated in fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is use assembling schematic diagram embodiment illustrated in fig. 1.
In figure: stirred vessel 1, upper cover 2, rocker arm 3, handle 4, shaft coupling 5, connector 5a, support member 6, fixed gear 7, moving gear 8, stirring vane 9, locating button 10,11, sealing ring 12, steam vent 13, connection tube 14, filter 15, negtive-pressure implement 16
The specific embodiment
Fig. 1～Figure 4 shows that the embodiment of a kind of bone cement mixer of the present invention, as shown in Figure 2, comprises stirred vessel 1, upper cover 2, rocker arm 3, handle 4, shaft coupling 5, support member 6, fixed gear 7, moving gear 8, stirring vane 9.
As depicted in figs. 1 and 2, handle 4 is arranged on the operating side of rocker arm 3, and the link of rocker arm 3 is positioned on upper cover 2.As shown in Figure 2, shaft coupling 5 has the connector 5a stretching laterally and is down " T " font in its lower end, shaft coupling 5 is being arranged on the middle part in upper cover 2 and being connected with the link of rocker arm 3 by locating button 10 through its upper end around the mode of its central shaft rotation.
As shown in Figure 2, support member 6 is fixed in upper cover 2 and is set in the outside of shaft coupling 5.Fixed gear 7 coaxially arrange and be set on support member 6 with shaft coupling 5 and be positioned at shaft coupling 5 its connector 5a above.Moving gear 8 be positioned at connector 5a above and with fixed gear 7 engagement (seeing Fig. 2 and Fig. 3).Stirring vane 9 be positioned at stirred vessel 1, connector 5a below, and by its upper end through locating button 11 being connected with moving gear 8 around the mode of its central shaft rotation.
As shown in Figure 2, between the present embodiment stirred vessel 1 and upper cover 2, be provided with sealing ring 12.On upper cover 2, be provided with steam vent 13(and see Fig. 1), as shown in Figure 4, during use, by this steam vent 13, through connection tube 14, be connected with negtive-pressure implement 16 with filter 15, with the bubble producing in emptying whipping process, the gas sucking-off of penetrating odor is drained simultaneously.
The present embodiment operation principle is as follows:
Cover upper cover 2, stirred vessel 1 bottom surface is steadily placed on platform, take stirred vessel 1 center is axis, with hands circumference swinging handle 4, drives rocker arm 3 to rotate around stirred vessel 1 central axis together with shaft coupling 5.Due to moving gear 8 with stirring vane 9 integral installations on shaft coupling 5, so moving gear 8 rotates around stirred vessel 1 central axis with shaft coupling 5 with stirring vane 9 integral body, thereby realizes the circumferential revolution of stirring vane 9.Meanwhile, by the engagement of the fixed gear 7 on moving gear 8 and support member 6, moving gear 8 rotatablely moved around the central axis of self with the whole while of stirring vane 9, thereby realized the rotation of stirring vane 9.Therefore, the existing revolution that is axis around stirred vessel 1 center of stirring vane 9 itself, also has the rotation around the central axis of self, thus reach comprehensive, without the thorough stirring at dead angle.
As shown in Figure 4, by steam vent 13, through connection tube 14, be connected with negtive-pressure implement 16 with filter 15, open the negtive-pressure implement 16 formation vacuum of can bleeding, the bubble producing in emptying whipping process is drained the gas sucking-off of penetrating odor simultaneously.Filter 15 can filter and intercept the bone cement floating particle that may kick up in whipping process, to avoid being adsorbed in negtive-pressure implement 16 and destruction equipment.
