Abstract
The utility model relates to a prefilled-type wash pipe syringe with an external-conicity-and top-sealed locked cap used to wash catheters. The prefilled-type wash pipe syringe is characterized in that a fixing drum is processed on the upper portion of a sleeve, a fixing-drum top plate is processed at the top of the fixing drum, a rubber seal ring is disposed above the fixing-drum top plate, a fixing-drum outer conical surface is processed on the outer side of the fixing drum, a fixing-drum thread is processed on the inner side of the fixing drum, and can be further connected with a cap thread in a matched manner. A cap conical surface is processed on the outer side of the cap thread, a cap seal plate is processed above the cap thread, and the cap conical surface is disposed on the outer side of the fixing-drum outer conical surface of the fixing drum. In conclusion, due to the fact that the cap conical surface is disposed above the fixing-drum outer conical surface of the fixing drum and the rubber seal ring is disposed between the fixing-drum top plate and the cap sealing plate, bacteria can be blocked from entering the insides of the locked cap and the sleeve.
Description
Technical field
The present invention relates to a kind of syringe, relate in particular to a kind of when irrigating catheter the locking of employed a kind of external taper and the top seal pre-filled washing pipe syringe of blocking a shot.
Background technology
Venous duct is a kind of therapy equipment commonly used, arranging of venous duct can conveniently be treated, for example can medicine be input in the human body by venous duct, and these conduits need wash in order to keep catheter patency and complete, the fluid of irrigating catheter is housed in the pre-filled washing pipe syringe, as pump pickle solution, heparin etc.
There are some problems in pre-filled washing pipe syringe on the market at present, the easy microbiological contamination in locked joints place, in case the joint microbiological contamination of a washing pipe syringe, in use have bacterial infection on venous duct and connector that the washing pipe syringe is connected, as positive pressure connector etc., when washing venous duct again, the antibacterial on the connectors such as positive pressure connector can be punched in the conduit, thereby enters human body.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming, and the locking of a kind of external taper that provides and the top seal pre-filled washing pipe syringe of blocking a shot, this invention is used for flushing, sealing venous duct.
The present invention is achieved in that the locking of a kind of external taper and the top seal pre-filled washing pipe syringe of blocking a shot, it is characterized in that: the top at sleeve is processed with stationary magazine creel, be processed with the stationary magazine creel top board at the top of stationary magazine creel, on the stationary magazine creel top board, rubber seal ring is installed, be processed with the stationary magazine creel male cone (strobilus masculinus) in the outside of stationary magazine creel, be processed with the stationary magazine creel screw thread in the inboard of stationary magazine creel, the stationary magazine creel screw thread can further be connected with the block threaded engagement, outside at the block screw thread is processed with the block conical surface, be processed with the cap sealed plate at block above the screw thread, in the outside of the stationary magazine creel male cone (strobilus masculinus) of stationary magazine creel the block conical surface be installed.
According to the locking of above-mentioned a kind of external taper and the top seal pre-filled washing pipe syringe of blocking a shot, owing on the stationary magazine creel male cone (strobilus masculinus) of stationary magazine creel, the block conical surface is installed, between stationary magazine creel top board and cap sealed plate, rubber seal ring is installed, and two the conical surface under the effect of block screw thread and stationary magazine creel screw thread, can produce accurate contact pressure between the two, so can stop antibacterial to enter the inside of locking block and sleeve, thereby guarantee that the effect for the treatment of is safe and reliable.
Description of drawings
Fig. 1 is the A-A cutaway view of Fig. 2 of the present invention
Fig. 2 is the vertical view of Fig. 1.
Each label declaration is as follows among the figure:
1, locking block, 2, the stationary magazine creel top board, 3, the block screw thread, 4, the stationary magazine creel screw thread, 5, stationary magazine creel, 6, the block conical surface, 7, rubber seal ring, 8, piston, 9, push rod, 10, sleeve, 11, push-rod handle, 12, the cap sealed plate, 13, the stationary magazine creel male cone (strobilus masculinus).
The specific embodiment
Locking block 1, block screw thread 3 and the block conical surface 6 are all selected polypropylene material time processing molding in mould for use, and rubber seal ring 7 selects for use the rubber processing of high-quality to make.The effect of locking block 1 is exactly the fastening effect by block screw thread 3 and stationary magazine creel screw thread 4, make between stationary magazine creel male cone (strobilus masculinus) and the block conical surface and produce accurate contact pressure, so can stop antibacterial to enter the inside of locking block and sleeve, thereby stop antibacterial to enter the inside of locking block 1 and sleeve 10.
Sleeve 10, stationary magazine creel 5, stationary magazine creel screw thread 4, stationary magazine creel top board 2, stationary magazine creel male cone (strobilus masculinus) 13, push rod 9 and push-rod handle 11 are all selected polypropylene material time processing molding in mould for use.Rubber seal ring 7 is installed on stationary magazine creel top board 2, rubber seal ring 7 selects for use the rubber processing of high-quality to make, its effect is exactly after stationary magazine creel male cone (strobilus masculinus) 13 and the conical surface 6 tight contacts of blocking a shot, this moment, rubber seal ring 7 produced compression, can further stop antibacterial to enter the inside that locks block and sleeve like this.The effect of stationary magazine creel 5 and stationary magazine creel screw thread 4 is exactly fixedly locked block 1.The effect of sleeve 10 is exactly to store medicinal liquid, sleeve 10 inside push rod 9 is installed, below push rod 9, be processed with push-rod handle 11, piston 8 is installed on push rod 9, piston 8 and push rod 9 are fixing by being threaded, the effect of push rod 9 is exactly fixed piston 8, and piston 8 is selected the top-quality rubber processing and fabricating for use.Mobile in sleeve 10 by catch bar handle 11 drive push rods 9 and piston 8 in use, thus the medicinal liquids in the sleeve 10 are sent in patient's the body by conduit.
In sum, the present invention is owing to be equipped with the block conical surface on the stationary magazine creel male cone (strobilus masculinus) of stationary magazine creel, between stationary magazine creel top board and cap sealed plate, rubber seal ring is installed, and two the conical surface under the effect of block screw thread and stationary magazine creel screw thread, can produce accurate contact pressure, so can stop antibacterial to enter the inside of locking block and sleeve.
