Compared with the prior three-way connecting vessels(shorted for three-way), the innovative structure changes the three-way to four-way, five-way and even six-way without increasing cost obviously. The utility model releases the necessity of using a plurality of three-ways at the same time in a clinical multi-way transfusion, which reduces the bother of connecting and fixing. Meanwhile, the multi-way connecting vessel also has the function of heparin cap which can realize a direct injection of medicines, blood sampling, sealing and indwelling without disconnecting the transfusion path. Thereby, the operation and nursing of clinical multi-way transfusion become more convenient. More important, the chance of bacterial contamination of blood can be reduced and the costs can be saved.
Description
This utility model is the multidirectional linker of a kind of medical infusion, belongs to medical mechanical domain.
In curative activity, be very important treatment measure through venous transfusion, and under a lot of situation, also need multiple liquid of infusion and medicine simultaneously.At this moment, a transfusion path is obviously not enough, generally uses a kind of three-dimensional linker (abbreviation threeway) to solve this a kind of problem clinically.But a threeway can only increase a transfusion and administration path, just can satisfy the demand for two or three so often need use simultaneously, is connected and fixed, and operation and nursing are all cumbersome, spend also high.And old-fashioned threeway do not possess the function of traditional calparine cap, can not direct injection, and blood sampling and sealing inlying catheter etc., carry out these operations, all will disconnect the transfusion path, not only trouble, and increase the chance that blood is invaded in germ contamination, obviously this is all very unfavorable to patient and medical personnel.
The purpose of this utility model is a kind of novel multidirectional linker of design.Under the situation of not obvious increase manufacturing cost, make old-fashioned threeway expand to four-way, five-way and even clematis stem, have the function of traditional calparine cap simultaneously concurrently, thereby make being connected and fixed of clinical multi-path transfusion administration, operation and nursing are more easy, and can direct injection, blood sampling and sealing inlying catheter etc. reduce the chance that blood is invaded in germ contamination, reduce medical expense simultaneously.
The novel multidirectional linker of this utility model design is compared with old-fashioned threeway, and agent structure still is made up of valve seat and spool two parts.The standard thread joint that has inflow and outflow for liquid and angiographic neeclle to be connected on the valve seat with other transfusion devices, its circular cylindrical interior surface and spool face closely cooperate, and the lower end can be sealed also and can open.For making spool be difficult for deviating from and prevent leakage, spool and valve seat cooperation place go up or and lower end (during the opening of valve seat lower end) the small annular projection and the groove that cooperatively interact are arranged.Spool can freely rotate, and the duct of inflow and outflow is for liquid also arranged on it, can communicate at the same time or separately with the duct on the valve seat and disconnect by rotation, thereby control the connection and the disconnection of many transfusion paths.All there is arrow the position of corresponding each aperture with the indication direction of rotation in the spool upper end, and a groove arranged respectively also above annular projection, when it goes to valve seat when connecing vein end (promptly being threaded an end of medicated cap), can match with a small embossment at its place, be rotated in place to show.Consider clinical different needs, this utility model has designed two kinds of structures.First kind changes spool into hollow type, be cylindric, lower end closed, the certain thickness rubber cap of lid is carried out in the upper end, and fixing seal, forms the structure of traditional calparine cap, both can increase the transfusion path by the puncture mode of rubber cap of venipuncture needle, make common threeway possess the function of calparine cap again, can direct injection, blood sampling and sealing inlying catheter etc.On the same horizontal plane of spool sidewall, in 180 ° of scopes, 90 ° have three apertures at interval, and it is corresponding with three apertures on the valve seat sidewall, can communicate simultaneously, constitute complete liquid communication duct, with these three same horizontal planes of aperture, avoiding and they positions of 90 ° and 180 ° at interval, also have an aperture, when spool rotates, when the aperture that connects vein end on this aperture and the valve seat is communicated, just can realize unidirectional drug administration by injection or transfusion, can not communicate with other two paths simultaneously, can not occur liquid refluence phenomenon during injection through rubber cap.90 ° aperture is when three apertures on the valve seat all communicate when three intervals on the spool, and multidirectional linker just is in the all-pass state, and all paths can be infused and administration simultaneously.Second kind of multidirectional linker increased a path again on first kind basis.Promptly on the bottom surface of valve seat sealing, open a scallop hole, connect a standard thread joint again by it.This moment, the cylindrical side wall and the bottom surface of valve seat and spool all closely cooperated, and scallop hole less scallop hole on can be by the spool bottom surface on the certain angle in valve seat bottom surface communicates with the cavity of spool.Aperture on the spool sidewall also is increased to five, and wherein three are still at interval 90 ° apertures, can be simultaneously with valve seat at interval three apertures of 90 ° communicate.At this moment, two scallop holes on the bottom surface also keep clear, and multidirectional linker is in the all-pass state, and all paths can be infused simultaneously.When spool rotates to an angle, when the aperture that one of two other aperture on the sidewall and valve seat connect vein end communicated, two scallop holes of bottom surface still kept communicating, and this moment, other four Kong Jun do not communicate with aperture on the valve seat, can realize the single-pass transfusion through this path of scallop hole.Spool continues rotation, and when a remaining aperture communicated with the valve seat vein end on the spool, the scallop hole that comprises the bottom surface all no longer communicated with aperture on the valve seat at other all apertures on the inner spool, can realize infusing through the single-pass of this path of rubber cap.Need to prove, two aperture position on the spool sidewall except that the aperture at 90 ° at three intervals should be avoided the position with 90 ° of these three spans and 180 °, and the interval angle between these two apertures also should be avoided 90 ° and 180 °, and when one of them when aperture on the valve seat communicates, other four apertures all do not communicate with three apertures on the valve seat.Directly be fixed on the inconvenience that may bring on the skin of vascular puncture position for fear of bigger linker in addition, also in order to operate the convenience of nursing, this utility model has designed one and has prolonged pipe, be used to connect venipuncture needle and linker, also have a tubing clamp on it, be used for interim blocking-up transfusion.
The multidirectional linker of this utility model design can select two kinds of different structures separately or be used according to clinical needs in use.First kind of function that calparine cap can be provided, and can increase by one to two transfusion path by mode with venoclysis needle puncture rubber cap; Path of second kind of then comparable first kind of more increase of linker.Prolonging Guan Ze is the use of cooperation linker, makes bigger linker can leave the venipuncture position, is convenient to fixing and operation, and the tubing clamp of outfit can be blocked venous channel temporarily when changing linker.
The advantage of the multidirectional linker of this utility model design is: 1. make old-fashioned threeway possess the function of traditional calparine cap simultaneously.In the spool design one-tenth with old-fashioned threeway
Empty, repack the structure of a traditional calparine cap dexterously into.This just makes new linker possess
Direct injection, the function of blood sampling and sealing inlying catheter but also can be by using vein
The mode of transfusion needle puncture rubber cap increases the transfusion path.2. make old-fashioned threeway can become four-way, five-way and even clematis stem.The novel linker of first kind of structure can increase by one to two transfusion path by the puncture rubber cap at least; Second kind then can path of more increases.And new linker still can be realized the conversion of all-pass state and every path single-pass state when increasing path.3. easy and simple to handle, nursing easily, the chance of blood is invaded in germ contamination in the minimizing infusion process.A novel linker can substitute the function of two or three old-fashioned threeways and a calparine cap at least, this has just been avoided using simultaneously a plurality of threeways to be connected with calparine cap and fixed trouble, prolong the also feasible operation of use of pipe and nurse convenient, especially reduced connecting link, needn't disconnect the transfusion path during administration blood sampling, just reduce the chance of germ contamination intrusion blood.4. economical and practical, reduce medical expenses.The manufacturing cost of novel linker and not obvious increase can substitute a plurality of old-fashioned threeways and calparine cap, obviously can reduce medical expenses.
