Background technology
Medical tee joint generally comprises into two, medicine passage, one of apocenosis passage.In operating process, there is a lot of hidden danger in existing Medical tee joint.Especially in the time being used in conjunction with central venous catheter, existing Medical tee joint is directly connected with central venous catheter, and while replacing, need to throw off conduit and threeway every day, in this process, the opening of central venous catheter is exposed in air, has greatly increased the chance of germ contamination.The technical problems such as in addition, existing Medical tee joint also exists in the time of the situations such as transfusion end or the violent cough of patient, and blood samples of patients can flow back in threeway and infusion pipeline, and medicinal liquid, blood are easily residual, rinse well, and its operation is very complicated.
Summary of the invention
This utility model, for shortcoming of the prior art, provides a kind of Medical tee joint.
In order to solve the problems of the technologies described above, this utility model is solved by following technical proposals:
Medical tee joint, comprises threeway, wherein two logical is respectively equipped with two flexible pipes, flexible pipe is provided with flow-stopping clip, and the flexible pipe other end is provided with calparine cap, and threeway is provided with connection tube, in connection tube, be provided with entry needle, entry needle comprises the needle body with tapered needle, and needle body upper end sidewall is provided with at least two side openings.
Connection tube in this utility model is connected with the calparine cap end of central venous catheter, entry needle in connection tube is directly inserted on the calparine cap of central venous catheter, reach simplification device, simplified the beneficial effect of nurse operation, greatly reduce infusion pipeline in prior art and often thrown off link, thereby reduce the technical problem of easy residual liquor, blood in germ contamination and Medical tee joint, the safety that improves critical patients central venous catheter.
The unidirectional wealthy lobe being provided with in this utility model threeway, has solved the technical problem that in prior art, blood easily refluxes; Needle body sidewall is provided with the side opening of different directions, in the time of punching envelope central venous catheter, and can be by clean drug irrigation residual the calparine cap inwall of central venous catheter.
As preferably, be provided with unidirectional valve at two flexible pipe opening parts.
As preferably, the root of at least one flexible pipe is provided with hand holding handle.The hand holding handle being provided with in this utility model, for nurse's operation has brought convenience, prevention, rushing in tube sealing or small dose drug intravenous injection process, when injection needle thrusts syringe pipe silicone rubber cap, is inserted nurse on hand by syringe needle because of carelessness.
As preferably, also comprise syringe pipe, syringe pipe is provided with silicone rubber cap.The syringe pipe being provided with in this utility model rushes tube sealing while end for low dose of intravenous injection medicinal liquid, transfusion.
As preferably, connection tube medial wall is provided with bayonet socket.The bayonet socket that connection tube medial wall is provided with, has guaranteed that connection tube is connected with the calparine cap of central venous catheter more firm, for operation has brought convenience, has also guaranteed patient's safety.
As preferably, entry needle top is lower than connection tube top.Entry needle top is lower than connection tube top, and after connection tube is connected with the calparine cap end of central venous catheter, side opening can reach the bottom of calparine cap completely.The damage of syringe needle, lower than the design on connection tube top, has not only been prevented in entry needle top, and can stab by preventive injection.
As preferably, the inner diameter of connection tube is identical with the outer diameter of calparine cap.Connection tube is connected with the calparine cap end of central venous catheter.
As preferably, side opening is circular side opening or oval side opening.
As preferably, in calparine cap, be provided with silicone rubber pad.
This utility model is owing to having adopted above technical scheme, there is significant technique effect: the connection tube in this utility model is connected with the calparine cap end of central venous catheter, entry needle in connection tube is directly inserted on the calparine cap of central venous catheter, reach simplification device, simplified the beneficial effect of nurse operation, reduce the link that in prior art, infusion pipeline is thrown off, bring thus in the chance of germ contamination and Medical tee joint the easily technical problem of residual liquor, blood, the safety that improves critical patients central venous catheter thereby reduce.This utility model needle body sidewall is provided with the side opening of different directions, in the time rushing tube sealing, reduces medicinal liquid, blood residual in the calparine cap of central venous catheter.The hand holding handle being provided with in this utility model, for nurse's operation has brought convenience, reduces pricking wound.And this utility model apparatus structure compactness, easy to operate.
