Abstract
The utility model belongs to the technical field of medical instruments and particularly relates to a transfusion apparatus. The transfusion apparatus comprises a transfusion tube, a drip tube, and a transfusion catheter. The transfusion tube is connected between the upper end of the drip tube and a medicine flask. The transfusion catheter is connected with the lower end of the drip tube. The drip tube, the transfusion tube, and the transfusion catheter are integrated. The transfusion apparatus is characterized in that a hollow floating ball is arranged in the drip tube. The radius of the floating ball is larger than the radius of the transfusion catheter. When liquid in the drip tube drains away, the floating ball drops with the liquid and is absorbed at a transfusion catheter mouth below the drip tube to jam the transfusion catheter, and thus blood backflow is avoided. The transfusion apparatus is simple in structure and safe in use.
Description
Technical field
This utility model relates to and belongs to the medical instruments technical field, is a kind of transfusion device specifically.
Background technology
Transfusion device in existing field comprises that connection-peg, tube for transfusion, weeping pipe, adjustment switch, syringe needle and muffler form, be connected with the air cleaning chamber between muffler, muffler also is connected with the adjustment switch, is provided with air vent on the air cleaning chamber, and capping is arranged on air vent.If transfusion device is the untimely syringe needle of pulling up after infusion-completed, endovascular blood will flow back in transfusion device, thereby produces adverse consequences.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of simple in structure, transfusion device of using safety is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of transfusion device, comprise tube for transfusion, weeping pipe and transfusion catheter, be connected with tube for transfusion between the upper end of weeping pipe and transfusion bottle, transfusion catheter is connected to the lower end of weeping pipe, weeping pipe and tube for transfusion, transfusion catheter are integrated, it is characterized in that being provided with in described weeping pipe a hollow ball float, the radius of described ball float is greater than the body radius of transfusion catheter.When weeping pipe liquid flows to end, thereby ball float is adsorbed on the transfusion catheter mouth of weeping pipe below along with liquid descends, and transfusion catheter is stopped up, and avoids backflow of blood.
This utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, after liquid in transfusion bottle flows to end, ball float is along with the interior liquid level of weeping pipe descends, thereby be adsorbed on the transfusion catheter mouth of weeping pipe below, reach the effect of cutout, thereby avoid occurring the phenomenon of backflow of blood.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment when infusing.
Fig. 2 is this utility model embodiment transfusion structural representation when completing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and this utility model is not limited to following examples.
Referring to Fig. 1 to Fig. 2, transfusion device in the present embodiment comprises transfusion bottle 1, tube for transfusion 2, weeping pipe 3, transfusion catheter 4 and ball float 5, be connected with tube for transfusion 2 between the upper end of weeping pipe 3 and transfusion bottle 1, transfusion catheter 4 is connected to the lower end of weeping pipe 3, weeping pipe 3 is integrated with tube for transfusion 2, transfusion catheter 4, be provided with a hollow ball float 5 in weeping pipe 3, the radius of ball float 5 is greater than the body radius of transfusion catheter 4.Ball float 5 can adopt ball, and the proportions such as baton round are less than the material of water.When weeping pipe 3 has liquid, ball float 5 floats (with reference to figure 1) under the effect of buoyancy, after the liquid in transfusion bottle 1 flow to end, ball float 5 was along with the liquid level in weeping pipe 3 descends, thereby be adsorbed on 4 mouthfuls of the transfusion catheters of weeping pipe 3 belows, transfusion catheter 4 is stopped up (with reference to figure 2).
In addition, need to prove, the specific embodiment described in this description, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this description is only to the explanation of this utility model structure example.All equivalence variation or simple change of doing according to the described structure of this utility model patent design, feature and principle are included in the protection domain of this utility model patent.
