The specific embodiment

Combine accompanying drawing that the present invention is further described at present:

By Fig. 1, shown in Figure 2ly know; The present invention is a kind of embodiment of the dosing adapter with stealthy needle tubing; Comprise pedestal 2; This pedestal 2 has first port and second port of mutual perforation, and usually pedestal is made up of top base 21 and base 22, on the external diameter of top base 21, be provided with screw thread 211 with being threaded of screw socket syringe 4; Said first port 211 is located at the male luer cone 41 that is used for socket syringe 4 on the top base 21, and said second port 221 is located at and is communicated with a fluid conduit systems fluid on the base 22; Slip is arranged with sealing-plug 1 in first port 211; The lower end of sealing-plug 1 is provided with orders about the elastic reset spare 11 that sealing-plug 1 moves to first port, 211 upper ends; Described base 22 internal fixation are arranged with needle tubing 3; The outlet 33 of this needle tubing 3 interlinks with second port 221 all the time; Under the section of first port, sealing-plug 1 has downward slippage and is made the top of needle tubing needle point 31 seal up the second position of first port 211 down by needle tubing 3 pierces through and the import 32 of needle tubing is exposed to sealing-plug 3 primary importance and elastic reset spare 11 elastic reactions the needle point 31 of this needle tubing 3 towards first port and lower.When adapter was in not dosing state, sealing-plug 1 was dosing mouth sealing with first port 211 under the elastic force of elastic reset spare 11, and when dosing; The male luer cone 41 of syringe 4 is moved at the top sealing-plug 1 downwards, needle tubing 3 puncture through seal plugs 1 and being inserted in the injection port 411 of male luer cone 41, thus medicinal liquid promptly can flow into second port 221 and then flow in the fluid conduit systems from needle tubing 3; Thereby accomplish dosing work, this dosing adapter utilizes built-in hiding needle tubing to replace the puncture function of entry needle on the common syringe in the past, its needle tubing not have to expose outside (being that needle point is under first end face that connect all the time) all the time; The situation that therefore people can not occur stabbing; In addition, structure is also simple, and processing is also convenient; In addition; Compare general Needleless connector, the medicinal liquid residual quantity is also less, is fed directly to needle tubing and flow into second port again and enter into fluid conduit systems because medicinal liquid is a male luer cone from syringe 4; The passage that flows through of medicinal liquid is less like this, and the passage of general Needleless connector can be bigger.

Needle tubing on the dosing adapter can be the needle tubing of common tilted mouth shape; The import that is needle tubing is on the axle center; But during the puncture of this needle tubing import is stopped up, so present embodiment adopts like Fig. 3, syringe needle shown in Figure 4, that is: described needle point 31 is positioned at the shaft core position of needle tubing 3; The side that the import 32 of needle tubing 3 is positioned near needle point 31 is provided with; Because the import 32 of needle tubing 3 is provided with in the side of needle tubing 3, and therefore needle tubing 3 is punctured thing and is difficult for stopping up import 32 along puncturing in the axis direction.

Described elastic reset spare can be spring independently; But the extra spring that is provided with both can cause dress to take trouble; Also have the alignment problem in addition and cause needle tubing to sting inclined to one side sealing-plug, so illustrated embodiment is set to the corrugated tube 11 that is wholely set with sealing-plug 1 with elastic reset spare, corrugated tube both elasticity is good; Be wholely set also with sealing-plug in addition and can effectively guarantee both axialities, and be wholely set the dress take also more convenient.
