Embodiment Construction
[0019] The present invention will be further described below with reference to the drawings and embodiments.
[0020] See figure 1 , figure 2 with image 3 , A cleaning device provided with a delivery nozzle plug, comprising a syringe 1, a piston that is sealed and slidably connected in the syringe 2, a push rod 3 extending from one end of the syringe connected to the piston, and a delivery nozzle cover 4. The other end of the syringe is provided with a delivery nozzle 11 and a connecting sleeve 12 sheathed outside the delivery nozzle. Internal threads are arranged on the inner surface of the connecting sleeve. The delivery nozzle cover 4 includes a tube body 41 and a flexible sealing sheet 42 that seals and isolates the inner space of the tube body into two parts. The pipe body is provided with an external threaded sleeve section 411 sheathed on the delivery nozzle and a grasping means 412 extending from the connecting sleeve. The outer threaded sleeve section is threadedly ...

The invention relates to a cleaner with a conveying nozzle plug. The cleaner comprises a syringe, a piston which is connected with the inner part of the syringe in sealing and sliding manners and a push rod which is connected with the piston and extends out from one end of the syringe, wherein a conveying nozzle is formed in the other end of the syringe; a conveying nozzle filling head is arrangedon the piston; the conveying nozzle is detachably connected with a conveying nozzle cover which can be used for enclosing the conveying nozzle; a liquid storage chamber is formed among the syringe, the piston and the conveying nozzle, and cleaning liquid is stored in the liquid storage chamber; the piston is moved to resist against one end, provided with the conveying nozzle, of the syringe, andthe volume of a space formed between the syringe and the piston is zero; and the conveying nozzle filling head is arranged in the conveying nozzle in a penetrating manner. The cleaner with the conveying nozzle plug provided by the invention has the advantages that the problems that the time consumption is long and the cleaning liquid is wasted heavily because a saline solution is extracted by adopting an existing injector to wash a catheter are solved.
Description
Technical field [0001] The invention relates to medical equipment, in particular to a cleaning device provided with a delivery nozzle plug and a tank drainage method. Background technique [0002] When inserting a needle into the patient to inject different medical solutions, it is sometimes necessary to clean the catheter on the needle with a cleaning solution (usually normal saline). The existing method for flushing the catheter is accomplished by taking a part of the saline from the whole package of saline by a syringe and then injecting it into the catheter. Since the normal saline solution must be extracted before the flushing can be performed, the flushing operation takes a long time; the air in the delivery nozzle will be mixed into the cleaning liquid during extraction, and the cleaning liquid must be discharged in order to discharge the gas, which will cause waste; There is cleaning fluid remaining in the delivery nozzle, causing waste. Summary of the invention [0003]...
