Description
Technical field
This utility model relates to transfusion device technical field, especially a kind of medical Transfusion device with blood return prevention function.
Background technology
Transfusion device is a kind of medical apparatus and instruments of infusing, traditional infusion method is that the liquid be contained in bottle is suspended on eminence, the effect of gravity is utilized to make liquid flow into intravenous by infusion rubber tubing, the size of flow by the clip be placed on leather hose to carry out manual adjustment, after the medicinal liquid in bottle terminates, as medical personnel pull out syringe needle not in time, due to the diffusion of liquid, the blood of human body can be back in the tube for transfusion of transfusion device, cause the bacteriological infection even various malpractice such as septicemia, the personal safety of harm patient.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem of transfusion device blood back, now provides a kind of medical Transfusion device with blood return prevention function.
This utility model solves the technical scheme that its technical problem adopts: a kind of medical Transfusion device with blood return prevention function, comprise perforator, dropping funnel, flow regulator, venoclysis needle and conduit, tubes connection is passed through between described perforator and dropping funnel, also comprise thin slice and pole, described perforator is made up of inner core and urceolus, described inner core and described tubes connection, the top of described urceolus is angle, the top of described inner core is flat mouth, one end of described pole is fixedly connected with described thin slice, the described pole other end inserts in the inner core of perforator, described thin slice can cover the flat mouth of inner core completely, the angle urceolus of perforator is used for piercing vials, pole is very long close with the height of infusion bottle, pole is inserted in the inner core of perforator, pole can ensure that thin slice can not disorderly waft in infusion bottle, and transfusion can drop in the flat mouth of the inner core of perforator after terminating, when there being liquid in infusion bottle, thin slice can float on a liquid, thus liquid can flow out from the flat mouth of inner core, along with liquid slowly reduces, thin slice also can follow decline, when liquid flows to end, thin slice can block the flat mouth of inner core, thus the thing of blood back would not be had to occur.
In order to make thin slice provide enough floatage energies to drive pole better to float further, the middle part of described thin slice is provided with protruding bubble.
In order to make thin slice better fit perforator inner core flat mouth further, the diameter of described protruding bubble is greater than the diameter of the flat mouth of inner core.
Preferably, described protruding bubble is ball-type.
The beneficial effects of the utility model are: the medical Transfusion device structure with blood return prevention function of the present utility model is simple, successful, by inserting the middle thin slice with protruding bubble in the inner core of perforator, thin slice declines along with liquid level and declines, realize infusing and terminate rear thin slice the flat mouth of inner core is blocked, effectively solve the problem of blood backflow.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is enforcement schematic diagram of the present utility model;
In figure: 1, protruding bubble, 2, urceolus, 3, infusion bottle, 4, thin slice, 5, inner core, 6, pole.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
Embodiment 1
A kind of medical Transfusion device with blood return prevention function as shown in Figure 1, comprise perforator, dropping funnel, flow regulator, venoclysis needle and conduit, tubes connection is passed through between perforator and dropping funnel, also comprise thin slice 4 and pole 6, perforator is made up of inner core 5 and urceolus 2, inner core 5 and tubes connection, the top of urceolus 2 is angle, the top of inner core 5 is flat mouth, one end of pole 6 is fixedly connected with thin slice 4, pole 6 other end inserts in the inner core 5 of perforator, and thin slice 4 can cover the flat mouth of inner core 5 completely.
Embodiment 2
With the difference of embodiment 1, embodiment 2 is that the middle part of thin slice 4 is provided with protruding bubble 1 as shown in Figure 1, and protruding bubble 1 is ball-type, and the diameter of protruding bubble 1 is greater than the diameter of the flat mouth of inner core 5.
Operation principle:
When there being liquid in infusion bottle 3, thin slice 4 can be suspended on liquid, thin slice 4 is positioned at the top of pole 6, pole 6 is very long close with the height of infusion bottle 3, pole 6 is inserted in the inner core 5 of perforator, pole 6 can ensure that thin slice 4 can not disorderly waft in infusion bottle 3, and transfusion can drop in the flat mouth of inner core 5 of perforator after terminating, when starting to infuse, piercing vials, thus liquid can flow out from the flat mouth of inner core 5, along with liquid slowly reduces, thin slice 4 also can follow decline, when liquid flows to end, thin slice 4 can block the flat mouth of inner core 5, protruding bubble 1 on thin slice 4 can well be fitted the flat mouth of inner core 5.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
