Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a novel infusion connects.
Background
In clinical medicine, when a patient needs to be transfused for many times, an external indwelling needle is usually used; the in vitro indwelling needle has better effect in clinical transfusion, and is particularly used for long-term transfusion of infant scalp needles and critically ill patients; the external indwelling needle adopted for the infant scalp needle can reduce the pain and psychological fear brought to infants by repeated puncture; the operation intensity of medical staff can be reduced besides the pain caused by repeated puncture for severe patients, the general transfusion time for the patients is longer, and the types of the used medicines are more, therefore, the traditional external indwelling needle needs the medical staff to inject the medicine into the main pipeline by using the side pipe at each time, and the labor intensity of the medical staff is greatly increased.
In the prior art, the external indwelling needle (commonly called as an infusion connector) generally comprises a main catheter with a puncture needle head (trocar), and the common external indwelling needle is divided into a positive pressure type and a negative pressure type, generally speaking, the negative pressure type is common, the side surface of the main catheter can be communicated with a side tube, the puncture needle of the main catheter extends into the vein of a patient, the other end of the main catheter is communicated with an infusion bag or an infusion bottle, if a medicament is required to be added, medical workers need to open the side tube, then the medicament is injected into the main catheter by using an injector, and the patient can be nursed by repeating the above operations.
In addition, hospital rescue is common and takes seconds for minutes. In rescue, 2-4 first-aid medicines are often applied at the same time. Generally, after the venous access is quickly established, a tee joint is connected between the infusion set and the trocar, and nurses statically push various emergency medicines into the bodies of patients through tee joint measuring holes according to medical orders.
There are problems: 1. the following process is carried out for each administration: the flow of opening the three-way knob, pushing the medicine and closing the three-way knob is easy to delay the rescue opportunity. 2. About 2 to 4 kinds of emergency drugs are commonly used in rescue, each drug is used for about 2 to 8 times, and the process is repeated repeatedly for a long time. 3. After the tee joint is closed, the connector is opened and is easy to be polluted. 4. When a plurality of medicines are applied at the same time, two or more tees are usually connected in series, and the connection position is easy to loosen, so that blood return and bleeding are caused. 5. The common tee joint is large in thickness and not easy to fix due to the adjusting device, and the bottom of the common tee joint is easy to press local skin to cause discomfort after the adhesive tapes are fixed.
The endovascular stent implantation operation is common, two tee joints are conventionally connected before an operation to be used by emergency medication or general anesthesia (multiple medicines are pumped simultaneously) in the operation, and four transfusion passages are usually required to be established within 24 hours after the operation: respectively used for inputting conventional medicines (removing oxygen free radicals), heparin sodium pump (preventing thrombosis in the stent), hydration medicines (promoting the excretion of contrast agent) and vasoactive medicines (controlling blood pressure), so that the tee joint is temporarily closed after the operation is finished, and the patient is reserved to return to a ward for continuous application. The above problems still remain.
