Above-mentioned nook closing member entrance is one or more.
When above-mentioned nook closing member entrance was a plurality of, described Lacrimal passage tube also comprised the second nook closing member, and described the second nook closing member and nook closing member are symmetricly set on body inside.
Above-mentioned body is the lumbar anesthesia pipe.
The material of above-mentioned nook closing member is rustless steel, rubber tube or medical plastics.
Advantage of the present invention is:
The present invention is improved to the aseptic Lacrimal passage tube of unpacking and just can directly use with the auxiliary tube body of traditional field fabrication, can be safe and reliable be used on the patient; Simultaneously, this Lacrimal passage tube is owing to being plugged with in advance the nook closing member in drag-out hole at the body internal direct, and the one or both ends of body pour into liquid all with side opening by the nook closing member water inlet that exposes, and is very easy to use.The 3rd, this body can be that one or both ends are provided with nook closing member simultaneously, is more convenient for medical and nursing work person, has shortened operating time, has simplified operation process.
Description of drawings
Fig. 1 is the structural representation of Lacrimal passage tube provided by the present invention;
Wherein:
The 1-body; The 2-side opening; The 3-nook closing member; 4-nook closing member entrance; The 5-lock valve; The 6-liquid injection port; The 7-liquid outlet.
The specific embodiment
Referring to Fig. 1, the invention provides a kind of Lacrimal passage tube, this Lacrimal passage tube comprise end sealing or closed at both ends body 1, be arranged on one or more nook closing member entrances 4 and nook closing member 3 on the body 1; Nook closing member 3 comprises liquid injection port 6 and liquid outlet 7; Nook closing member 3 stretches into the body 1 from nook closing member entrance 4; Body 1 also is provided with side opening 2 near the position of the liquid outlet 7 of nook closing member 3; The liquid injection port 6 of nook closing member 3 is exposed in body 1 outside, the purpose that one or more nook closing member entrances 4 are set is exactly so that the length of Lacrimal passage tube is adjustable, can be according to the needs of different condition, nook closing member 3 can directly stretch into from different nook closing member entrances 4 body 1, perform the operation, need not be again to again carrying out the pore-creating operation on the body 1.
The present invention in use, to the liquid injection port perfusion fluid on the nook closing member 3, enter body 1 inside behind the liquid outlet 7 via nook closing member 3, when liquid is full of or partly be full of body 1, because body 1 internal pressure effect, so that the liquid of body 1 inside is from being arranged on side opening 2 ejections on the body 1.
Lacrimal passage tube also comprises the lock valve 5 that is arranged on the liquid injection port 6 that is used for locking nook closing member 3 on the nook closing member 3, and the effect of this lock valve 5 is exactly, to make it be difficult for flowing out via the control of the liquid in the liquid injection port 6 within it.
In order to guarantee being perfectly safe of body 1, specially an end setting that contains liquid outlet 7 on the nook closing member 3 is blunt circle, can easily nook closing member 3 be slided to efficiently the position of required arrival.
For the ease of two lacrimal passage tubules are performed the operation simultaneously, the present invention also improves the nook closing member 3 of Lacrimal passage tube, and except above-mentioned nook closing member 3, the present invention also comprises the second nook closing member, and the second nook closing member and nook closing member 3 are symmetricly set on body 1 inside.
No matter be above which kind of embodiment, the material of body 1 can be lumbar anesthesia pipe or the superfine tube for transfusion of bore of commonly using.Material for nook closing member can be rustless steel, rubber tube or medical plastics.
Because the selected material of the present invention all is medical, sterilizable, so the present invention is in use, just can not cause various injuries to human body, very safe.
