Abstract
The utility model discloses a one-way valve tee-joint for drainage and injection instruments, to resolve the problem of the prior art that the drainage and injection operations are inconvenient. The main technique solution for resolving the technique problem is that provide a one-way valve tee-joint for the drainage device, the structure of the one-way valve tee-joint comprises a tee-joint valve body, which is provided with three channels inside, the three channels are connected with the injection connector, the one-way input valve, and the one-way output valve respectively. The utility model is mainly used to perform puncturing drainage therapy for the effusion and pneumatorsis in the human body, is also suitable for medicine injection therapy for vascular and body cavity through guidance tube or puncturing needle, and can also be used for air injection to the body cavity. The utility model is simple in operation and practical, improves the efficiency of work dramatically, and the effect is reliable.
Description
Technical field: this utility model belongs to medical check valve threeway technical field, particularly a kind of drain, injecting apparatus check valve threeway.
Background technology: pathologic pneumatosis, hydrops are common disease performances in the body, need aspiration drainage during treatment more.In clinical position, the drainage equipment of drain and injection generally is that syringe, drainage tube and puncture needle directly are connected use.In use, drain for a large amount of pneumatosis hydrops, or medicine, gas etc. are to intravital injection, the operator needs under the assistant assists, use syringe repeated multiple times and drainage tube to peg graft and disconnection, so that extraction, drain pneumatosis and hydrops, or inject gas, liquid and accurately quantitative, it is very inconvenient to operate.
Summary of the invention: the technical problems to be solved in the utility model is that injection and drain need to peg graft repeatedly to disconnect operation inconvenience in clinical.
The technical scheme of this utility model technical solution problem is, for drainage device provides a check valve threeway, the structure of check valve threeway comprises triple-valve body, be provided with three passages in the triple-valve body, three passages are connected with syringe union joint, one-way input valve, unidirectional delivery valve respectively, form input channel and output channel, be respectively equipped with input union joint and output union joint on one-way input valve and the unidirectional delivery valve, the input union joint is respectively applied for puncture needle with the output union joint and is connected with drainage bag.
Input channel is linked in sequence by syringe union joint, threeway main body, one-way input valve and input union joint and forms.
Be linked in sequence by syringe union joint, threeway main body, unidirectional delivery valve and output union joint in output channel and form.
When exchanging above-mentioned check valve and operating, can oppositely finish to intravital implant operation with being connected of puncture needle.Be that puncture needle is connected with the output union joint of delivery valve, the input union joint of transfer valve is connected with medication device.
During use, drainage procedure can will be imported union joint and be connected with the puncture needle end after puncture successfully, and syringe links to each other with the syringe union joint; The output union joint can link to each other or not have and be connected with drainage bag etc.During syringe pump, one-way input valve is opened, and unidirectional delivery valve cuts out, and aspirate enters syringe by puncture needle through input union joint, one-way input valve, triple-valve body, syringe union joint; When syringe was injected, one-way input valve was closed, and unidirectional delivery valve is opened, and drain is discharged through syringe union joint, triple-valve body, check valve delivery valve and output union joint by syringe, and the amount of drain can be shown by syringe graduation.Take out repeatedly and finish drain and quantitative work when pushing away syringe.Implant operation is similar to the drainage procedure principle.
This utility model is mainly used in the puncture drainage treatment of hydrops in the human body, pneumatosis, also be applicable to through conduit or puncture needle in blood vessel, endoceliac medicine injects treatment, also can be used for injecting to endoceliac gas.Have simple to operate, practical, significantly improve work efficiency and advantage reliable for effect.
