Description
Technical Field
The invention relates to the field of medical appliances, in particular to a dual-purpose duplex mixing injector connecting piece and a duplex mixing injector.
Background
The existing duplex mixing injector on the market cannot be simultaneously suitable for two use modes of a coating type and a cavity mirror type, so that doctors cannot switch the use modes at any time according to the use requirements in the operation process. The common method is to simultaneously configure two products, namely a coating type special duplex mixing injector and a cavity mirror type special duplex mixing injector, and a doctor can only use one specific type duplex mixing injector according to the needs when using the special duplex mixing injector. If two using modes of coating type and endoscope type are needed for one operation, two sets of duplex mixing syringes with different types are usually needed to be prepared, and two sets of medical spraying reagents are simultaneously prepared, and the medical spraying reagents are generally expensive, so that unnecessary waste is caused, and the economic burden of a patient is increased; or when a doctor needs to switch the use mode, the two injection barrels are manually detached from one type of duplex mixing injector and then are assembled on the other type of duplex mixing injector again, so that the operation is extremely inconvenient in operation, the operation time is prolonged, and the operation risk is increased.
In order to avoid the advanced mixing of two medicaments, the mixing position is arranged at the nozzle position of the cavity mirror type duplex mixing injector, and the factor determines that the connection between the three-way pipe module of the duplex mixing injector and the long nozzle is required to be designed into an integrated structure with good sealing property, so that the advanced mixing of the two reagents before reaching the nozzle is avoided. The common solution is to integrate the whole duplex mixing injector tee pipe module with the long nozzle, but the solution cannot be processed by injection molding due to the limitation of the processing technology of plastic products. Therefore, most manufacturers have employed the addition of metal lumen tubes to address this problem. However, the metal cavity tube has no good sterilization scheme at present, and only can be sterilized by gas, which is a sterilization mode with low efficiency.
Another possible solution is to design the duplex mixing syringe tee module to be detachably connected to the long nozzle. However, as the nozzle part of the cavity mirror type duplex mixing injector is in common threaded connection, the two channels of the three-way pipe module of the duplex mixer are difficult to be in just sealing butt joint with the two channels of the long nozzle in the threaded rotation process. Once the docking inaccuracy occurs, the two liquids of the duplex mixer are mixed in advance without reaching the nozzle, and the problem of gel blocking occurs.
Therefore, the existing duplex mixing injector cannot quickly switch between the coating type and the cavity mirror type using modes. There is a need to design a dual hybrid syringe connector and dual hybrid syringe that can be adapted for both coated and endoscopic applications and that can be quickly switched.
