Abstract
The utility model relates to detachable syringe filter and digestion instrument and to draw a design the joint design of head.This joint design comprises (1) buckle, connects digestion instrument and to draw a design head; (2) handle, is convenient to installation and removal; (3) interface, connects detachable syringe filter suitable for reading.Joint component in laboratory in available disposable filter, disposable light proofing infusion apparatus and disposable syringe (VACLOK 30mL) obtains voluntarily.This joint can connect digestion instrument and to draw a design head and detachable syringe filter, replaces disposable syringe filter, greatly reduces experimental cost.
Description
Technical field
The utility model relates to the detachable syringe filter that uses before the sample introduction of laboratory and digestion instrument and to draw a design the joint design of head.
Background technology
Pharmaceutical Analysis room and each drug test unit, all need various chromatographic apparatus and digestion instrument sampling collection system.All need to carry out sample pre-treatments before drug-eluting liquid sample introduction.Disposable filter can be directly installed on drawing a design between head and sampling probe of digestion instrument, but due to disposable filter cost high, need a large amount of disposable filters when carrying out stripping curve comparison, disposable filter be restricted in the use in laboratory.
Utility model content
The purpose of this utility model is to provide a kind of detachable syringe filter (Fig. 3) and digestion instrument and draws a design the joint of head (Fig. 1), this joint is made up of buckle (1), handle (2) and interface (3), wherein buckle (1) and digestion instrument head of drawing a design is connected, handle (2) is convenient to installation and removal, and interface (3) is connected with detachable syringe filter.This inner nosepiece wall is smooth cavity, and upper cavity can be combined with tapped standard luer fittings, and lower cavity can insert the top of another same joint, and leakproofness is good.Connect digestion instrument with it to draw a design head and detachable syringe filter, replace and use disposable filter, realize filtered sample, reduce laboratory cost.
In order to the problem existing for technical solution background, the utility model is by the following technical solutions:
1. the excision of disposable filter center section is discarded, the otch of the first half and the latter half is polished flat, is bonded together.
2. the parts of connecting needle and woven hose in disposable light proofing infusion apparatus are taken off, this parts the latter half is polished applicable detachable syringe filter is suitable for reading.
3. the flexible pipe excision in the middle of the line member in disposable needle tubing is discarded, polish the otch of two end portions, be bonded together with bonding agent, then the buckle outside outlet is excised.
4. removed by the movable buckle of the switch block head in disposable needle tubing, these parts are more satisfactory joint, because these parts are with switch, if experimental session changes filter membrane, can closing switch, and drip so as not to liquid.
Accompanying drawing illustrates:
Fig. 1 to draw a design head for sampling collection system, and Fig. 2 is structural representation sketch of the present utility model, and Fig. 3 is detachable syringe filter.
Embodiment:
Below in conjunction with example, the utility model is elaborated.Digestion instrument sampling collection system mentioned in this article is RZQ-8D.Disposable filter cited below is for buy on the market, and disposable light proofing infusion apparatus is derived from Shandong Xinhua Ande Medical Articles Co., Ltd., and disposable syringe is
vACLOK30 mL syringes.
Embodiment 1:
With reference to Fig. 1, the parts of connecting needle and woven hose in disposable light proofing infusion apparatus are taken off, this parts the latter half is polished applicable detachable syringe filter is suitable for reading.
Embodiment 2:
With reference to Fig. 1, the excision of disposable filter center section is discarded, the otch of the first half and the latter half is polished flat, is bonded together.
Embodiment 3:
With reference to Fig. 1, the flexible pipe excision in the middle of the line member in disposable needle tubing is discarded, polishes the otch of two end portions, be bonded together with bonding agent, then the buckle outside outlet is excised.
Embodiment 4:
With reference to Fig. 1, removed by the movable buckle of the switch block head in disposable needle tubing, these parts are more satisfactory joint, because this component locations (3) place is with switch, experimental session needs to change filter membrane, can closing switch, drips so as not to liquid.
Connect digestion instrument sampling collection system in application in turn to draw a design head (Fig. 1), utility model (Fig. 2) and detachable syringe filter (Fig. 3).
Claims (2)
1. detachable syringe filter and digestion instrument are drawn a design the joint design of head, it is characterized in that this joint is made up of buckle (1), handle (2) and interface (3), wherein buckle (1) and digestion instrument head of drawing a design is connected, handle (2) is convenient to installation and removal, and interface (3) is connected with detachable syringe filter.
2. joint design as claimed in claim 1, it is characterized in that inwall is smooth cavity, upper cavity can be combined with tapped standard luer fittings, and lower cavity can insert the top of another same joint, and leakproofness is good.
