Description
Technical field
This utility model relates to the sealed safe transfusion tube of medical tube for transfusion, particularly thrum.
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 elastic packing formula safe transfusion tube easy to use, safe.
The purpose of this utility model is achieved in that a kind of elastic packing formula safe transfusion tube, comprises the minim pipette body, and wherein: be provided with dividing plate in the described body, dividing plate is provided with at least one middle part through hole, liquid sealing between the neighboring of dividing plate and the inboard wall of tube body; Be provided with float in the body on dividing plate top, the lower end of float is connected with closure plate; Body internal fixation at the lower partition has support, and support is provided with fluid passage, is provided with at least one elastomer between support and closure plate, and this elastomer passes dividing plate, and its upper/lower terminal is fixedlyed connected with support with closure plate respectively; The big I of closure plate covers the through hole on the dividing plate fully, contacts sealing between the lower surface of closure plate and the upper surface of dividing plate.
Elastomer described in the above-mentioned elastic packing formula safe transfusion tube is good with spring, is preferably disposed on support and closure plate middle part.
After this utility model adopts said structure, because of the lower surface of closure plate can with the upper surface of dividing plate between form and contact sealing, after transfusion is finished, the intravital liquid level position of minim pipette pipe reduces gradually, float is with moving down under liquid level reduction and the elastomeric elastic force, the drive closure plate moves down, when the lower surface of closure plate with form sealing after the upper surface of dividing plate contacts, can guarantee like this tube for transfusion after transfusion is finished can with air insulated, prevent in the air admission body, simultaneously also can prevent backflow of blood, 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 is a user mode sketch map of the present utility model.
Among the figure: 1 body, 2 dividing plates, 2A through hole, 3 floats, 4 closure plates, 5 supports, 5A fluid passage, 6 elastomers.
The specific embodiment
A kind of elastic packing formula safe transfusion tube comprises minim pipette body 1, is provided with dividing plate 2 in body 1, and dividing plate 2 is provided with a middle part through hole and a plurality of liquid through-hole 2A, liquid sealing between the neighboring of dividing plate 2 and body 1 inwall; Be provided with float 3 in the body 1 on dividing plate 2 tops, the lower end of float 3 is connected with silica gel closure plate 4, and the big I of closure plate 4 covers the through hole 2A on the dividing plate 2 fully, contacts sealing between the upper surface of the lower surface of closure plate 4 and dividing plate 2. Body 1 internal fixation in dividing plate 2 bottoms has support 5, support 5 is provided with fluid passage 5A, is provided with an elastomer 6 between support 5 and closure plate 4 middle parts, and elastomer 6 is a spring, elastomer 6 passes the middle part through hole 2A of dividing plate 2, and its upper/lower terminal is fixedlyed connected with support 5 with closure plate 4 respectively.
As shown in Figure 1 and Figure 2, when this utility model specifically uses, liquid level during normal infusion in the body 1 exceeds dividing plate 2, float 3 overcomes elastomer 6 under buoyancy function elastic force up moves, the lower surface of silica gel closure plate 4 is not contacted with the upper surface of dividing plate 2, and transfusion liquid flows to body 1 bottom through the through hole 2A of dividing plate 2, the through hole 5A of support 5 after entering through body 1 top, outlet output from body 1 lower end enters human body then, realizes 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, float 3 constantly descends with liquid level under the combined effect of the elastic force of gravity own and elastomer 6, driving silica gel closure plate 4 moves down, when the liquid level of body 1 bottom arrives certain position, the lower surface of silica gel closure plate 4 contacts with the upper surface of dividing plate 2, form the contact sealing, make tube for transfusion and air insulated, prevent in the air admission body 1, also can prevent backflow of blood simultaneously, reach the purpose of safe handling.
