Abstract
The utility model provides a water sealing safe transfusion catheter, which comprise a dropper tube body, wherein a liquid outlet on the lower end of the tube body is provided with a water sealing tube; the tube wall of the water sealing tube higher than the liquid outlet of the tube body is provided with a fluid passage; a closed sleeve tube is arranged outside the water sealing tube; the inside diameter of the closed sleeve tube is longer than the outside diameter of the water sealing tube; the contact surface of the lower end of the closed sleeve tube and the inner wall of the lower part of the tube body is lower than the fluid passage; the upper end of the closed sleeve tube is connected with a floater; the distance between the top part of the floater and the top part in the tube body is smaller than the height of the water sealing tube. The utility model, which has the advantages of simple structure and use safety, is used for human body transfusion.
Description
Technical field
This utility model relates to medical tube for transfusion, is meant a kind of hydrolock 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 guiding buoy type safe transfusion tube easy to use, safe.
The purpose of this utility model is achieved in that a kind of hydrolock safe transfusion tube, comprise the minim pipette body, wherein: the liquid outlet of described body lower end is provided with water sealing (sealing water) pipe, be provided with fluid passage at the water sealing (sealing water) pipe tube wall that is higher than the body liquid outlet, be provided with closed casing outside water sealing (sealing water) pipe, the internal diameter of closed casing is greater than the external diameter of water sealing (sealing water) pipe; The contact surface of closed casing lower end and body lower inner wall is lower than fluid passage; Be connected with float in the closed casing upper end, the distance between float top and the body inner top is less than the height of water sealing (sealing water) pipe.
Water sealing (sealing water) pipe described in the above-mentioned hydrolock safe transfusion tube is that the outlet tube by the body lower end extends in body and forms, and fluid passage is the groove that extends along the water sealing (sealing water) pipe tube wall, and so easy processing is to reduce manufacturing cost.
This utility model utilizes between closed casing and the water sealing (sealing water) pipe and forms water-stop, and utilize water sealing (sealing water) pipe as the upper and lower mobile guide way of closed casing after adopting said structure, and is simple and practical; After transfusion is finished, the intravital liquid level position of minim pipette pipe reduces gradually, the guide effect that float is reduced in water sealing (sealing water) pipe with liquid level down and closed casing move down, when the lower end of closed casing contacts with inboard wall of tube body, form water-stop between closed casing and the water sealing (sealing water) pipe, 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 water sealing (sealing water) pipes, 2A fluid passage, 3 closed casings, 4 floats.
The specific embodiment
As shown in Figure 1, hydrolock safe transfusion tube of the present utility model comprises minim pipette body 1, and the liquid outlet in body 1 lower end is provided with water sealing (sealing water) pipe 2, and water sealing (sealing water) pipe 2 is that the outlet tube by body 1 lower end extends in body 1 and forms; Be provided with fluid passage 2A at water sealing (sealing water) pipe 2 tube walls that are higher than body 1 liquid outlet, fluid passage 2A is the groove that extends along water sealing (sealing water) pipe 2 tube walls; Be provided with closed casing 3 outside water sealing (sealing water) pipe 2, the internal diameter of closed casing 3 is greater than the external diameter of water sealing (sealing water) pipe 2; The contact surface of closed casing 3 lower ends and body 1 lower inner wall is lower than fluid passage 2A; Be connected with float 4 in closed casing 3 upper ends, the distance between float 2 tops and body 1 inner top is less than the height of water sealing (sealing water) pipe 2.
As shown in Figure 1 and Figure 2, this utility model is when concrete the use, liquid level during normal infusion in the body 1 is higher, float 4 up moves under buoyancy function, drive on the closed casing 3 and move, at this moment the lower end of closed casing 3 is than the fluid passage 2A height of water sealing (sealing water) pipe 2 tube walls, after transfusion liquid is crossed body 1 top and entered, gap between closed casing 3 and water sealing (sealing water) pipe 2, fluid passage 2A 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, float 4 constantly descends with liquid level under the effect of gravity own, driving closed casing 3 moves down, when the liquid level of body 1 bottom arrives certain position, when the lower end of closed casing 3 is low than the fluid passage 2A of water sealing (sealing water) pipe 2 tube walls, form water-stop between closed casing 3 and the water sealing (sealing water) pipe 2, 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.
