Abstract
The utility model discloses a dual-chamber drop funnel used for blood transfusion device, which includes a drop funnel kettle, a dropper and a filter which are arranged in the drop funnel kettle, wherein, the dropper is arranged in the middle of the drop funnel kettle and is connected with the inner wall of the drop funnel kettle in a sealing manner, while the dropper divides the inner cavity of the drop funnel kettle into an upper cavity and a lower cavity as the extrusion cavities, and the filter is arranged in the lower cavity of the drop funnel kettle. As the utility model adopts the technic proposal, in the blood transfusion process, the peripheral wall of the upper cavity of the drop funnel kettle can be pinched back and forth to input the blood in the human body compulsively and rapidly, thus to make the pressure of the upper cavity of the drop funnel kettle push downward, then the utility model can greatly increase the blood transfusion volume in the unit time for the patients with the urgent need of substantial blood transfusion, thereby providing the convenience to save the critical patients and alleviating the sufferings of the patients.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to the double-cavity drop funnel on a kind of blood exchange transfusion set of being used for.
Background technology
Existing medical blood exchange transfusion set comprises needle for inserting bottle, flexible pipe, dropping funnel, flow regulator and venoclysis needle etc., needle for inserting bottle is by hose connection upper end to the dropping funnel kettle, the dropping funnel (see figure 1) is made up of dropping funnel kettle 1 and the dropper 2 and the filter 3 that are arranged in the dropping funnel kettle 1, dropping funnel kettle 1 is generally made with injection moulding or plastic uptake and expressing technique by PVC material, has certain elasticity; Dropper 2 is positioned at the upper end of dropping funnel kettle 1, and dropper 2 oozes 20 liquid of bleeding and is about 1ml; Filter 3 is positioned at the bottom of dropping funnel kettle 1, and it is blocked in the impurity in the blood on the filter and the energy blood clean.But, coagulation matters in the blood and impurity can be in the blood transfusion process blocking filter 3, influencing transfusion speed even occlude blood filters, when the critical patient need quicken to transfuse blood, usually the maneuver of taking in clinical is to pinch the perisporium of dropping funnel kettle 1 back and forth, to inflation in the dropping funnel kettle 1 its pressure is increased, to guarantee finishing smoothly of the process of transfusing blood.But because the construction features of existing dropping funnel and the restriction of dropper 2 flows, under the effect of squeeze pressure, its transfusion speed does not still satisfy the critical illness human needs.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the double-cavity drop funnel on a kind of blood exchange transfusion set of being used for is provided, and it can make blood force to import human body fast to being badly in need of the patient of a large amount of blood transfusions.
The purpose of this utility model is achieved by following technical scheme, a kind of double-cavity drop funnel that is used on the blood exchange transfusion set, comprise the dropping funnel kettle, be arranged on dropper and filter in the dropping funnel kettle, wherein, described dropper is positioned at the middle part of dropping funnel kettle and is connected with the inner wall sealing of dropping funnel kettle and dropping funnel kettle inner chamber is divided into epicoele and cavity of resorption as extrusion chamber, and described filter is arranged in the cavity of resorption of dropping funnel kettle.
The above-mentioned double-cavity drop funnel that is used on the blood exchange transfusion set, wherein, the epicoele of described dropping funnel kettle and the length ratio of cavity of resorption are 0.9～1.2: 1.
The above-mentioned double-cavity drop funnel that is used on the blood exchange transfusion set, wherein, described dropper is a funnel-form, it is to connect by hot pressing that its inner wall sealing with the dropping funnel kettle is connected.
The above-mentioned double-cavity drop funnel that is used on the blood exchange transfusion set, wherein, described filter is filtering screen or web plate.
Owing to adopted the technical solution of the utility model, in the blood transfusion process, when the critical patient need quicken to transfuse blood, force to import human body fast for making blood, can pinch the perisporium of dropping funnel kettle epicoele back and forth, the pressure of dropping funnel kettle epicoele is pushed away downwards, can increase the transfusion volume of unit interval greatly, provide convenience for rescuing the critical patient, alleviated patient's misery.
Description of drawings
Fig. 1 is the structural representation that is used for the dropping funnel on the blood exchange transfusion set of prior art;
Fig. 2 is the structural representation of the double-cavity drop funnel on the blood exchange transfusion set of being used for of the present utility model.
The specific embodiment
See also Fig. 2, double-cavity drop funnel on the blood exchange transfusion set of being used for of the present utility model comprises dropping funnel kettle 1, dropper 2 and filter 3, dropping funnel kettle 1 is generally made with injection moulding or plastic uptake and expressing technique by PVC material, wherein, dropper 2 is positioned at the middle part of dropping funnel kettle 1 and is connected with the inner wall sealing of dropping funnel kettle 1 and dropping funnel kettle 1 inner chamber is divided into epicoele 11 and cavity of resorption 12, epicoele 12 is as extrusion chamber, the epicoele 11 of dropping funnel kettle 1 is 0.9～1.2: 1 with the length ratio of cavity of resorption 12, dropper 2 preferably is positioned at the length center of dropping funnel kettle 1, this dropper 2 is a funnel-form, and it is to connect by hot pressing that its inner wall sealing with dropping funnel kettle 1 is connected.
Described filter 3 is arranged in the cavity of resorption 12 of dropping funnel kettle 1, and it can be filtering screen or web plate.
Owing to adopted the technical solution of the utility model, in the blood transfusion process, when the critical patient need quicken to transfuse blood, force to import human body fast for making blood, can pinch the perisporium of dropping funnel kettle epicoele 11 back and forth, the pressure of dropping funnel kettle epicoele 11 is pushed away downwards, can increase the transfusion volume of unit interval greatly.
Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
