Abstract
The utility model discloses a disposable self-exhausting precision liquid-stop transfusion device which comprises a puncture outfit, a drip chamber, a liquid flow regulation device, a liquid medicine precision filter, a split-type spiral connector and a terminal self-exhaust protective jacket. A first transfusion catheter is in serial connection with a second transfusion catheter. The first transfusion catheter before the drip chamber is provided with a plurality of medicine feeding transfusion connectors. The second transfusion catheter between the liquid flow regulation device and the liquid medicine precision filter is provided with a medicine feeding transfusion connector. According to the disposable self-exhausting precision liquid-stop transfusion device, transfusion is carried out on clinical patients, and meanwhile combined with treatment requirements, other liquid medicine can be conveniently and quickly added through the various medicine feeding transfusion connectors arranged on the first transfusion catheter and the second transfusion catheter. In terms of medical treatment, the disposable self-exhausting precision liquid-stop transfusion device can be widely applied to transfusion of clinical central venous catheters and peripheral intervention central veins and others.
Description
One, technical field
This utility model belongs in a kind of medicine and hygiene fields the infusion set of using when carrying out venous transfusion to clinical patients, and specifically relating in venous transfusion can secondary filter gas, the disposable infusion set tool of safe infusion and medication.
Two, background technology
At present, in medical treatment is clinical, by venipuncture transfuse blood, transfusion or drug injection are modal method in the treatment clinical disease patient process.Yet, existing medical personnel carry out in the treatment of venipuncture blood transfusion, transfusion or drug injection for the clinical disease patient, be generally venous transfusion, because the various diseases situation is different or be subjected to the restriction of the condition of clinical disease patient own, long-term repeatedly transfusion needing repeatedly can occur or in the single transfusion, will repeatedly add injecting medical liquid and the situation of frequent transfusion device or medicine container temporarily, easily pollute thereby increase very large workload and transfusion device to medical personnel, cause increase medical personnel's pressure and bring infection to cause unnecessary misery to the clinical disease patient.
Three, utility model content
The purpose of this utility model is to provide a kind of disposable use from the accurate liquid transfusion device that ends of aerofluxus, with overcome existing venoclysis needle, entry needle is carrying out the clinical disease patient in the treatment of venipuncture blood transfusion, transfusion or drug injection, may need prolonged and repeated repeatedly puncture transfusion or in the single transfusion, will repeatedly add injecting medical liquid and frequent transfusion device or medicine container temporarily, bring very large pressure and clinical disease patient to bring the defective of unnecessary misery to medical personnel.
The purpose of this utility model is achieved in that the disposable use of this utility model is from the accurate liquid transfusion device that ends of aerofluxus, comprise that perforator, dropping funnel, fluid flow regulator, precise liquid medicine filter, split type screwed union and terminal are from exhaust jacket, they are cascaded by the first transfusion catheter and the second transfusion catheter, it is characterized in that: also be provided with several medicine-adding infusion connectors on the first transfusion catheter before described dropping funnel.
Further, this utility model also can arrange medicine-adding infusion connector by the second transfusion catheter between described fluid flow regulator and precise liquid medicine filter.
This utility model is when giving clinical disease patient transfusion, combined treatment needs, can be by being arranged at each medicine-adding infusion connector on first, second transfusion catheter, other medicinal liquids of easily and quickly annotating, because need not to change transfusion device or medicine container can not increase medical personnel's operating pressure, can not cause transfusion device to infect yet, it is safe and reliable, easy to use, can effectively avoid the non-artificial viral and pathogenic cross infection that causes, have the meaning that is highly profitable to stopping malpractice.It can be widely used in the clinical center venous duct in aspect medical and periphery gets involved the transfusions such as central vein.
Four, description of drawings
Fig. 1, be according to the structural representation that the utility model proposes.
Five, the specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is further described:
Labelling among the figure: 1, perforator; 2, the first transfusion catheter; 2-1, the second transfusion catheter; 3, dropping funnel; 4, fluid flow regulator; 5, precise liquid medicine filter; 6, split type screwed union; 7, terminal is from exhaust jacket; 7-1, ventilation type sheath; 7-2, ventilated membrane; A, medicine-adding infusion connector.
In the drawings, the disposable use of this utility model is from the accurate liquid transfusion device that ends of aerofluxus, comprise that perforator 1, dropping funnel 3, fluid flow regulator 4, precise liquid medicine filter 5, split type screwed union 6 and terminal are from exhaust jacket 7, they are cascaded by the first transfusion catheter 2 and the second transfusion catheter 2-1, it is characterized in that: also be provided with several medicine-adding infusion connectors A on the first transfusion catheter 2 before described dropping funnel 3.
Further, this utility model also can arrange medicine-adding infusion connector A by the second transfusion catheter 2-1 between described fluid flow regulator 4 and precise liquid medicine filter 5.
In actual applications, this utility model is when giving clinical disease patient transfusion, combined treatment needs, can be by being arranged at each medicine-adding infusion connector A on the first transfusion catheter 2 and the second transfusion catheter 2-1, other medicinal liquids of easily and quickly annotating, thereby effectively the clinical disease patient is treated, further improved quality of medical care and usefulness.
In addition, in order further to strengthen the safety of transfusion, this utility model has also been done optimization process to the terminal that is connected in split type screwed union 6 from exhaust jacket 7, described terminal is designed with ventilation type sheath 7-1 and ventilated membrane 7-2 from exhaust jacket 7 in its end, in order to can effectively gas filtrations all in the transfusion device be fallen, thereby realized the self-purging purpose of transfusion device.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that to those skilled in the art, under the prerequisite that does not break away from this utility model principle, can also make some modification and improvement, this also is considered as belonging to protection domain of the present utility model.
