Abstract
The invention discloses a drainage apparatus and relates to the technical field of medical instruments. The drainage apparatus comprises a venous catheter and a drain catheter. An adapter is connected between the venous catheter and the drain catheter and comprises an adapting sheet internally provided with a through hole. The diameter of an upper outlet of the through hole is greater than that of a lower outlet. The upper outlet is connected with an upper round tube big end down. The lower outlet is connected with a lower round tube big end up. The drainage apparatus is applicable to draining hydrops. Compared with the prior art, the drainage apparatus allows the poor tightness problem of the connection of the venous catheter and the drain catheter to be solved.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of device for drain hydrops.
Background technology
General hydrops drain is with being drained into external by device by the hydrops in patient, the paper that nursing magazine the 13rd volume the 4th in 2007 in Shandong is interim: central venous catheter is used for disclosing a kind of venous drainage device in drain pleural effusion Clinico-pathological study, comprise puncture needle, and the syringe to be connected with this puncture needle and venous duct, this venous duct is connected with drainage bag by drainage catheter, can be drained by hydrops when not carrying out multiple punching.The shortcoming existed is: venous duct does not mate with the interface of drainage catheter, connects imprecision, easily occurs coming off and leaking gas, and causes sepage, sufferer infection equivalent risk.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of drainage system, and it can solve venous duct and be connected imprecise problem with drainage catheter.
In order to solve the problem, the technical solution adopted in the present invention is: this drainage system, comprise venous duct and drainage catheter, conversion head is connected with between described venous duct and drainage catheter, described conversion head comprises in it conversion sheet being provided with through hole, the diameter of the upper outlet of described through hole is greater than the diameter of lower outlet, and described upper outlet is connected with up-small and down-big upper pipe, and described lower outlet is connected with up big and down small lower pipe.
In technique scheme, technical scheme can also be more specifically: described upper pipe comprises column casing, and described column casing is provided with the up-small and down-big flexible pipe be connected with described venous duct.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The conversion head be communicated with siphunculus by through hole is housed between venous duct and drainage catheter, the two ends of this conversion head are mated with venous duct and drainage catheter respectively and are connected, hydrops is made to flow out to conversion head from venous duct, drainage catheter is flow into again by conversion head, enter in drainage bag, solve venous duct and be connected imprecise problem with drainage catheter, be not easy to occur that connection comes off and leaks gas.

Fig. 2 is the top view of embodiment 1.
Fig. 3 is the A-A direction view of embodiment 1.
Fig. 4 is the structural representation of embodiment 2.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Embodiment 1:
The embodiment of drainage system as shown in Figure 1, Figure 2 and Figure 3, comprise venous duct and drainage catheter, conversion head is connected with between described venous duct and drainage catheter, described conversion head comprises in it conversion sheet 1 being provided with through hole, the diameter of the upper outlet 1-1 of described through hole is greater than the diameter of lower outlet 1-2, described upper outlet 1-1 is connected with up-small and down-big upper pipe 2, and described lower outlet 1-2 is connected with up big and down small lower pipe 3.
During work, be connected by upper pipe 2 with venous duct, be connected with drainage catheter by lower pipe 3, hydrops flows into conversion head from venous duct, flows through pipe 2 successively, upper outlet 1-1, lower outlet 1-2, lower pipe 3, then flows into drainage catheter.
Embodiment 2:
Described upper pipe 2 comprises column casing 2-1, and described column casing 2-1 is provided with the up-small and down-big flexible pipe 2-2 be connected with described venous duct, and described column casing 2-1 and flexible pipe 2-2 forming station scalariform, other features are identical with embodiment 1.
Claims (2)
