Abstract: A filter needle for a syringe including a syringe needle having a needle, a fixing member for fixing the needle and an inner space formed in the fixing member, and a syringe body having a cylinder, a piston and a front end separably installed in the inner space of the fixing member of the syringe needle, is provided. The filter needle includes a filter structure installed in the inner space of the fixing member of the syringe needle and including an one-way inlet path having an inlet and an one-way outlet path having an outlet, each of which has a check valve function, and a filter installed in the outlet path at a rear end of the outlet to filter a foreign substance, which is input through the inlet together with a medicament liquid, from the medicament liquid such that the medicament liquid is only injected into a patient through the outlet when injecting the medicament liquid into the patient.

Abstract: Disclosed is a filter needle in which a filter structure is embedded in the inner space of a fixing member of a syringe needle. The filter structure has an inlet and an outlet, each of which functions as a check valve, and an inlet path and an outlet path provided with a filter, wherein the inlet path and the outlet path are formed at the rear end of the filter structure. Thus, when a medicament liquid flows out from the ampoule and injected into a patient, foreign substances, such as powder generated during the opening of an ampoule, which otherwise might be introduced into the main body of a syringe and injected into a patient, are filtered by a filter. The filter needle enables the medicament liquid to be injected into the patient without exchanging the syringe. The filter needle is integrally formed of medical silicone to enable easy assembly and safety during use.

Abstract: The present invention relates to a syringe, and more particularly, to a syringe, in which, when liquid medicine for treatment such as an analgesic is suctioned into a syringe by using a syringe needle and injected into a human body through the syringe needle, foreign substances generated in an ampule and the like are filtered in the syringe when the liquid medicine is injected into the human body when the foreign substances are suctioned into the syringe through the syringe needle. In addition, the filter for the filtering has a simple structure so that the filter can be simply installed into the syringe.

Abstract: Provided are a virtual computing accelerator and program downloading method for server-based virtual computing. The virtual computing accelerator divides a program allocated to a virtual memory into groups, such as pages or segments, and downloads the groups of program data in sequence. Here, the groups of program data are downloaded after download sequence is estimated on the basis of statistical data accumulated in a hash table, or only a part that must be first downloaded is downloaded in advance. Thus, a program-execution wait time of a client can be reduced. In addition, only a part of a possibly required program is transferred in advance, and the client can execute the application program using only a small amount of virtual memory.
