Abstract
The utility model provides a floater type safe transfusion catheter, which comprises a dropper tube body, wherein a floater is arranged in the tube body; the lower end part of the floater is provided with an elastic sealing sheet; at least two fixed connection points are arranged between the elastic sealing sheet and the inner wall of the tube body; a partition board is also arranged in the tube body on the lower side of the elastic sealing sheet; the middle part of the partition board is provided with a liquid through hole; the periphery of the partition board and the inner wall of the tube body are sealed through liquid; the size of the elastic sealing sheet can cover the liquid through hole on the partition board; the lower surface of the elastic sealing sheet and the upper surface of the partition board are sealed through contacts. The utility model, which has the advantages of use convenience and safety, is used for human body transfusion.
Description
Technical field
This utility model relates to medical tube for transfusion, is meant a kind of buoy type safe transfusion tube especially.
Background technology
At present, widely used traditional tube for transfusion in clinical treatment, its dropper (Jimo Fes pipe) needs medical personnel constantly to observe liquid level in use, preventing that transfusion from finishing in the air admission tube for transfusion of back reaches backflow of blood, there is use inconvenience in this traditional tube for transfusion, increased medical personnel's labor intensity, the application's designer is through research, invented can seal automatically after a kind of transfusion is finished, tube for transfusion safe in utilization.
Summary of the invention
The purpose of this utility model is to provide a kind of a kind of guiding buoy type safe transfusion tube easy to use, safe.
The purpose of this utility model is achieved in that a kind of buoy type safe transfusion tube, comprise the minim pipette body, wherein: be provided with float in the described body, be connected with elastic sealing strip in the float bottom, be provided with at least two fixed connection point between this elastic sealing strip and the inboard wall of tube body, also be provided with dividing plate in the body of elastic sealing strip downside, the dividing plate middle part is provided with liquid through-hole, liquid sealing between the neighboring of dividing plate and the inboard wall of tube body; The big I of elastic sealing strip covers the liquid through-hole on the dividing plate, contacts sealing between the lower surface of elastic sealing strip and the upper surface of dividing plate.
Elastic sealing strip described in the above-mentioned buoy type safe transfusion tube with square be good, fixedly connected with inboard wall of tube body for its four jiaos.
After this utility model adopts said structure, can be under the buoyancy tractive of float because of elastic sealing strip, disengage between the lower surface that makes elastic sealing strip and the upper surface of dividing plate, thereby form fluid passage, the realization normal infusion; After transfusion is finished, liquid level position reduces, the buoyancy of float is not enough to the tractive elastic sealing strip, make the lower surface of elastic sealing strip contact the formation sealing with the upper surface of dividing plate, can guarantee like this tube for transfusion after transfusion is finished can with air insulated, prevent in the air admission body, also can prevent backflow of blood simultaneously, improve the usage safety performance of tube for transfusion.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing this utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of this utility model;
Fig. 2 be among Fig. 1 A-A to the sectional structure sketch map;
Fig. 3 is a user mode sketch map of the present utility model.
Among the figure: 1 body, 2 floats, 3 elastic sealing strips, 4 dividing plates, 4A liquid through-hole.
The specific embodiment
Embodiment 1
As shown in fig. 1, buoy type safe transfusion tube of the present utility model, comprise pipe shape minim pipette body 1, in body 1, be provided with spherical float 2, be connected with square silica gel elastic sealing strip 3 in float 2 bottoms, four jiaos of this elastic sealing strip 3 with body 1 inwall between fixedly connected, in the body 1 of elastic sealing strip 3 downsides, also be provided with dividing plate 4, dividing plate 4 middle parts are provided with liquid through-hole 4A, liquid sealing between the neighboring of dividing plate 4 and body 1 inwall; Contact sealing between the upper surface of the lower surface of elastic sealing strip 4 and dividing plate 2.
As Fig. 1, shown in Figure 3, when this utility model specifically uses, liquid level during normal infusion in the body 1 is higher, float 2 is tractive elastic sealing strip 3 under buoyancy function, the upper surface of elastic sealing strip 3 and the upper surface of dividing plate 4 are disengaged, and transfusion liquid flows to body 1 bottom through the liquid through-hole 4A of dividing plate 4 after entering through body 1 top, enter human body from the outlet output of body 1 lower end, realize normal infusion; When in the infusion bottle during no liquid, body 1 top no liquid flows into, the liquid level of body 1 bottom descends gradually, the buoyancy of float is not enough to tractive elastic sealing strip 3, make the upper surface of elastic sealing strip 3 contact the formation sealing with the upper surface of dividing plate 4, make tube for transfusion and air insulated, prevent in the air admission body 1, simultaneously also can prevent backflow of blood, reach the purpose of safe handling.
Claims (2)
