Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of liquid transfusion device that ends automatically.
Background technology
At present, when hospital carries out venous transfusion to clinical patients, generally use disposable transfusion device, like this, to preventing that the cross infection between the patient from playing a good role, yet, use this disposable transfusion device also to exist weak point, be that current disposable transfusion device does not have automatic sealing process when transposing infusion bottle and transfusion end, will in time change dressings liquid bottle or pull out transfusion needle, otherwise can entering tube for transfusion, air can bring unsafe factor to the patient, in case the nursing staff does not note or inadvertent at this moment a little, the backflow of blood of clinical patients returns tube for transfusion and causes patient's fear, and simultaneously thrombosed dangerous meeting bring the factor that is absolutely unsafe to clinical patients and cause malpractice and the treatment that is unfavorable for clinical patients easily, has increased nursing staff's stress and operating pressure.At present, good solution is not also arranged.
The utility model content
Technical assignment of the present utility model is to provide a kind of liquid transfusion device that ends automatically at above-mentioned deficiency of the prior art, should end the liquid transfusion device automatically has when medicinal liquid is totally lost or is changed the medicinal liquid bottle, can automatically infusion channel be closed, stop air admission patient vein, both guaranteed the infuse safety of overall process of patient, alleviate patient and medical worker's stress and operating pressure again, can prevent the reflux characteristics of formation of the panic and thrombosis of the patient cause of blood effectively.
The technical scheme that its technical problem that solves this utility model adopts is: it comprises tube for transfusion, perforator, dropping funnel, flow regulator and transfusion needle, described perforator and transfusion needle are separately positioned on the two ends of tube for transfusion, described dropping funnel and flow regulator are separately positioned on the tube for transfusion, tube for transfusion between described dropping funnel and the flow regulator is provided with one and ends liquid device automatically, the described liquid device that ends automatically comprises connector and ends liquid film, described connector comprises upper connector and following connector, the described liquid film that ends comprises front diaphragm and rear film, the two ends, the left and right sides of described front diaphragm and rear film link to each other, two ends link to each other with following connector with upper connector respectively up and down, described upper connector and following connector the other end link to each other with tube for transfusion respectively, the inner chamber of described upper connector and following connector respectively with the tube for transfusion intracavity inter-connection.
The described connector that ends the liquid film outside is provided with a guard shield.
Described perforator is provided with the perforator medicated cap, and described transfusion needle is provided with the pin medicated cap.
Automatically the liquid transfusion device that ends of the present utility model is compared with prior art; have following outstanding beneficial effect: tube for transfusion is provided with and ends liquid device automatically; when medicinal liquid is totally lost or is changed the medicinal liquid bottle; can automatically infusion channel be closed; stop air admission patient vein; both guaranteed the infuse safety of overall process of patient; patient and medical worker's stress and operating pressure have been alleviated again; to reach the usefulness of vein safe infusion; can prevent the reflux formation of the panic and thrombosis of the patient cause of blood effectively; help the treatment to clinical patients, this is for further minimizing and avoid the very positive meaning that has of malpractice, characteristics such as easy to use.
