Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-6, the present utility model provides a technical solution:
In a first embodiment of the present invention,
An integrated peritoneal dialysis solution sample collector comprising:
the plastic shell 2 is fixedly connected to the outer side of the storage tube 1, the plastic shell 2 and the storage tube 1 can be detachably connected in a threaded mode or in a fastening mode, and a hollow needle head 3 is fixedly connected to the inner part of the plastic shell 2;
The protection mechanism 4, protection mechanism 4 installs between plastic casing 2 and cavity syringe needle 3, and protection mechanism 4 pierces the protection before the waste liquid bag to cavity syringe needle 3, can protect to cavity syringe needle 3 before not getting the sample liquid through protection mechanism 4, in cavity syringe needle 3 also can retract protection mechanism 4 after the sample, and then can reduce medical personnel's danger under the prerequisite of conveniently gathering the sample liquid.
The protection mechanism 4 comprises a rubber plug 41 which is slidably connected in the plastic shell 2, the needle tip of the hollow needle 3 is inserted into the rubber plug 41, the outer sides of the rubber plug 41 and the plastic shell 2 are wrapped with a protection cap 42, and the protection cap 42 can protect the rubber plug 41 and the hollow needle 3, so that the risk of injury to medical staff before the product is not used is reduced.
The outside fixed connection rubber circle 43 of plastic casing 2, protection cap 42 is seted up flutedly corresponding to rubber circle 43 positions, and the external diameter of recess is less than the external diameter of rubber circle 43, and rubber circle 43 can be when protection cap 42 inserts plastic casing 2 outside, and is spacing to protection cap 42, reduces the unexpected possibility that drops of protection cap 42, further makes things convenient for the lock of protection cap 42.
