Abstract
The utility model provides a medical bi-way transfusion device for the technical field of the medical device, which is characterized in that both sides of the upper end of a cone are provided with an air outlet and a liquid inlet whose position is lower than the air-out port position. Compared with the prior art, the utility model has the advantage that the air in the transfusion bottle cannot enter the human body with the medical liquid via the vein.
Description
Technical field:
This utility model belongs to technical field of medical instruments, is a kind of medical bilateral transfusion device.
Background technology:
One end of existing medical bilateral transfusion device is provided with a cone that is used for inserting infusion bottle, empty in the cone, and be provided with dividing plate, dividing plate will bore the chamber be divided into about two passages, the lower end of two passages links to each other with tube for transfusion with air inlet pipe respectively, offer gas outlet and inlet respectively two passage upper ends, because the position of gas outlet and inlet is on same horizontal plane, the size of suffered pressure is the same, so in infusion process, in the time of near the medicinal liquid in the infusion bottle drops to inlet, air enters human body with medicinal liquid by vein easily in the bottle, and patient body is caused damage.
Summary of the invention:
The purpose of this utility model provides a kind of in infusion process, and in the time of near the medicinal liquid in the infusion bottle drops to inlet, air can not enter human body to the hurtful medical bilateral transfusion device of patient body by vein with medicinal liquid in the bottle.
The technical scheme that this utility model adopted is: improved on the basis of existing medical bilateral transfusion device, have cone, its main feature is: offer gas outlet and inlet on the both sides of cone upper end, the position, gas outlet is higher than the inlet position.
The medical bilateral transfusion device that adopts technique scheme to make, the position, gas outlet is higher than the inlet position, and inlet place pressurized is powerful in the gas outlet, compared with prior art has the interior air of infusion bottle and can not enter characteristics such as human body with medicinal liquid by vein.
Description of drawings:
Fig. 1 represents cone structure sketch map of the present utility model.
The specific embodiment:
This utility model is improved the cone 3 of existing medical bilateral transfusion device, the position of air inlet 1 is opened on the position that is higher than inlet 2, because the position of air inlet 1 is higher than inlet 2, the suffered hydraulic pressure of air inlet 1 is less than the suffered hydraulic pressure of inlet 2, so air in air inlet 1 enters bottle, in the time of near medicinal liquid is reduced to inlet 2, can be in tube for transfusion enter patient's body with medicinal liquid.
In this case embodiment 1, the position consistency of gas outlet on the cone of 1 position, gas outlet and existing transfusion device, inlet 2 is opened in the 1 pair of side lower part in gas outlet, differs one centimetre with 1 position, gas outlet.Reduce to inlet 2 when the bottle herb liquid and should in time stop transfusion when following.
Claims (1)
1, a kind of medical bilateral transfusion device is improved on the basis of existing medical bilateral transfusion device, has cone, and it is characterized in that: offer gas outlet and inlet on the both sides of cone upper end, the position, gas outlet is higher than the inlet position.
