Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.
Referring to the accompanying drawings 1-2, an improved medical tee assembly is shown, the tee assembly is formed by sequentially connecting a plurality of medical tees 1, each medical tee 1 is provided with a first through hole 1a, a second through hole 1b and side holes 1c which are mutually communicated, and the distance between the side holes 1c of the connected medical tees 1 is preferably 1.8cm. The side wall of the medical tee joint 1 at one end and the symmetrical position of the side hole 1c thereof are detachably provided with plugging components which are connected with and plugged by the side hole 1c of the medical tee joint 1. As shown in figure 1, the medical three-way component is formed by sequentially connecting 4 medical three-ways 1 in series. It can realize 5 venous access, and when needs stop temporarily a route infusion, through will shutoff subassembly is dismantled, with the medical tee bend 1 that treats to close side opening 1c is connected the shutoff that realizes this side opening 1c, and then realizes that this venous access blocks fast. Similarly, when other passages need to be blocked, the side hole 1c of the corresponding medical tee 1 is connected with the blocking component to perform corresponding blocking operation. This tee bend subassembly has higher flexibility to and higher infection risk when avoiding conventional separation single pass, still reduce nurse's work load simultaneously, improve work efficiency, and save patient's medical expense.
Specifically, as shown in fig. 1, an assembly column 11 (preferably, 1cm in length) is arranged on a side wall of the medical tee 1 at one end, and the plugging component is a spare protective cap 2 (preferably, a cylinder shape with 1cm in length, width and height) detachably sleeved on the assembly column 11. Preferably, the spare protective cap 2 is connected with the assembling column 11 in a threaded fit manner, and when a certain venous access needs to be blocked by the spare protective cap 2, the spare protective cap 2 is rapidly disassembled and assembled to the corresponding side hole 1c of the medical tee joint 1 (preferably, the spare protective cap 2 is also sealed by the threaded connection with the side hole 1c of the medical tee joint 1), so that rapid sealing and plugging are performed.
In order to further effectively shorten the assembly time of the spare protective cap 2 and the corresponding side hole 1c and reduce the risk of infection, as shown in fig. 1, a blind hole (not shown in the figure, the aperture of which is preferably 0.5 cm) is formed in the assembly column 11, and a positioning plugging head 21 extending into the blind hole is arranged in the spare protective cap 2, and the positioning plugging head 21 can be tightly fitted and arranged in each side hole 1 c. After the standby protective cap 2 and the assembling column 11 are quickly rotated and disassembled, the positioning plugging head 21 of the standby protective cap 2 is arranged in the corresponding side hole 1c in a penetrating mode (the preferable positioning plugging head 21 is slightly attached to and slidable with the inner wall of the side hole 1 c), the standby protective cap 2 and the side hole 1c are coaxially positioned, quick threaded matching of the standby protective cap 2 and the side hole 1c can be achieved, the problem that the standby protective cap 2 and the side hole 1c jump, clamping stagnation and sliding of threads and damage of inner and outer threads due to rotation deflection of the standby protective cap 2 during manual operation is avoided, the plugging duration is prolonged, the infection risk is increased, and the problems that the standby protective cap 2 and the side hole 1c jump, and the inner and outer threads are damaged can be further caused.
In order to avoid the problem of air bubbles caused by liquid delivery of a main pipeline after the side hole 1c of the single medical tee joint 1 is plugged, the outer end of the positioning plugging head 21 is flush with the inner side wall of the medical tee joint 1 in the state that the side hole 1c is fixedly penetrated. The device aims to extend the positioning plugging head 21 to the port of the side hole 1c and avoid the defect of liquid conveying bubbles caused by the fact that a cavity is formed in the side hole 1c after plugging.
The utility model discloses the principle of nature is: the main realization of the three-way component is that when one passage needs to be temporarily stopped for infusion, the standby protective cap 2 is rotationally disassembled and connected with the side hole 1c of the medical three-way 1 to be closed, so that the side hole 1c is blocked, and the vein passage is quickly blocked.
Similarly, when other passages need to be blocked, the spare protective cap 2 is connected to the side hole 1c of the corresponding medical tee 1 to perform corresponding blocking operation. This tee bend subassembly has higher flexibility, can increase and decrease the vein route at will to and higher infection risk when avoiding the single route of conventional separation, still reduce nurse's work load simultaneously, improve work efficiency, and save patient's medical expense.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
