Disposable anti-liquid residue formula pressurization blood transfusion/liquid device

Technical field

This utility model relates to a kind of medical disposable bionic type pressurization blood transfusion/liquid device, especially a kind of disposable anti-liquid residue formula pressurization blood transfusion/liquid device.

Background technology

Traditional transfusion device (referring to nineteen ninety transfusion device in the past) can be infused and also can transfuse blood (because of medicinal liquid has 1,100 kinds, blood also belongs to liquid, belongs to a kind of of medicinal liquid), and is to reuse behind the cleaning and sterilizing, and its defective is: 1. cleaning and sterilizing extremely bothers; 2. the long-term public cross infection that easily causes; 3. because of its tube for transfusion is the glue goods, dropping funnel is a glass, and does not have blood filter, and the fat drop in its blood or the erythrocyte of cohesion and clot have the danger that causes thromboembolism.Guangdong People's Hospital, Guangdong Provincial TCM Hospital, the Guangdong Province traditional Chinese medical science Second Academy, Guangzhou General Hospital Guangzhou Military Command, hospitals such as each Affiliated Hospital of Guangzhou Zhongshan Medical Univ. and attached Nanfang Hospital of No.1 Military Medical Univ. have adopted " disposable use blood exchange transfusion set " (manufacturer: Guangdong dragon heart medical treatment device machine company limited of a kind of advanced person in recent years, factory site: Bulbus Lilii town, Kaiping City, Guangdong Province, postcode: 529375. phones: 0750-2510676. fax: 0750-2510688), this " disposable use blood exchange transfusion set " is actually a kind of " Y " shape blood transfusion/liquid device, and (following conduit with dropping funnel/Dripper type blood filter top is called dropper, and the conduit of below is called tube for transfusion; Switch on the dropper is called switch, switch on the tube for transfusion is called flow regulator), during use, transfusion bottle stopper puncture needle on one of them dropper (blood dropper) is injected in the interface of bags of blood lower end, transfusion bottle stopper puncture needle on another dropper (medicinal liquid dropper) is injected in the mouth of infusion bottle, at first open the medicinal liquid dropper and set up the row blood transfusion more afterwards of venous transfusion passage, when blood transfusion finishes, bags of blood is inverted and reduces its position, the interior medicinal liquid of infusion bottle this moment washes owing to liquid level difference (drop) enters in the bags of blood, and then bags of blood hung up, just major part can be sticked to the remained blood input human body on the bags of blood inwall, not only avoid waste but also guaranteed curative effect, and set up blood filter in the lower end (also can say above dropping funnel) of total dropper, compared marked improvement with traditional transfusion device, but it is the same with anything, also need constantly perfect, its existing major defect is: 1. do not have liquid medicine filter on the medicinal liquid dropper, can not filter medicinal liquid; 2. when patient's changing position (as: hang bottle is gone up a toilet, the auxiliary examination or in the open air of transferring from one department to another), in case the infusion bottle position is lower, the danger of generation blood reflux (because of there is pressure in intravenous) is arranged, the possibility that the blood coagulation tube for transfusion stops up takes place if untimely processing has, again operation not only very bothers, and also can incur loss through delay rescue opportunity and cause waste; 3. when blood transfusion/liquid is last eventually, the liquid residue phenomenon is often arranged in the tube for transfusion, its main cause exists the individual variation of pressure and venous pressure relevant with intravenous, especially blood, precious liquid and therapeutic dose is had medicinal liquid residual of strict demand, not only can affect the treatment, but also can cause the blood transfusion/liquid of waste, particularly infant, original total amount of liquid just seldom often affects the treatment because of residual; 4. when needs pressurize fast blood transfusion/liquid, owing to the defective of self structure aspect, must be by special pressurized equipment or utensil, not only the randomness of its operation is poor, and its special pressurized equipment or utensil usually be public for a long time, easily causes cross infection; 5. when a large amount of blood transfusions (generally more than 800ml), its blood filtration net is often stopped up by fat drop in the blood or the erythrocyte that gathers, if change the blood exchange transfusion set again, and its operation trouble comparatively not only, and often have blood residual and waste in the depleted blood exchange transfusion set of institute;
