Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and specifically, this utility model relates to a kind of human body end harvester of blood collection slightly.
Background technology
Medical institutions often need gather the human body end slightly blood chemically examine, at present be to inhale the elongated collection tube of ball after gather slightly at the human body end basically with band, again the collection tube mouth of pipe is stretched in the collecting pipe, with the end slightly blood pressure be put in the collecting pipe, collecting pipe is placed on the laboratory is detected, chemical analysis, this method is simple, easy to operate, but there are some problems in this method: the one, gather the end slightly during blood, after needing to gather with collection tube earlier, repress is put in the collecting pipe, collection and collection process need be shifted and finish, and easily cause biochemical the pollution in moving process; The 2nd, need sometimes to gather repeatedly, the end that just can collect specified volume is blood slightly, gathers, acquisition time is longer; The 2nd, at present domestic elongated collection tube is generally made by glass, with this collection tube the child is carried out the end slightly during the blood collection, if child's hands is touched the easier child's of scratching of elongated collection tube who is made by glass hands then.
The utility model content
This utility model is at the deficiencies in the prior art, proposes a kind of simple in structurely, and safety is good, can realize gathering, collects continuously, " locked in " operation, thereby avoid gathering, cause biochemical self-closed type end of polluting blood collection tube slightly because of shifting function in the gatherer process.
This utility model is achieved through the following technical solutions technical goal.
The self-closed type end is the blood collection tube slightly, and it comprises both ends open, leptosomatic collection tube and collecting pipe, and described collecting pipe is an open-topped tubular container; Its improvements are: described collection tube adopts polypropylene to make, and inwall is through silicidation; The pipe cap that is nested and closes with the collecting pipe top mouth of pipe is set, and described pipe cap is made by elastomeric material, and it is made of cap and medicated cap body; Described medicated cap body is that axial cross section is the circle tube member of " H " type, and cap is the flange that turns up that is connected medicated cap body top; 3～5 protruding circular arc rings are set on the outer wall of medicated cap body lower end constitute the elastic tensioning structure, protruding circular arc ring external diameter bottom is than the big 0.5～0.9mm of collecting pipe internal diameter, and all the other protruding circular arc ring external diameters are than the big 0.2～0.4mm of collecting pipe internal diameter; Port is provided with the taper guiding structure in medicated cap body lower end, is connected with protruding circular arc ring bottom is slick and sly; Connect seal cover in medicated cap body inwall middle and lower part, described seal cover is that axial cross section is " V " type thin-wall member, 3～6 vertical masonry joints by the center is set constitutes self-enclosed structure.
In the said structure, described pipe cap is made by T-shaped glue.
This utility model compared with prior art has following good effect:
1. simple in structure, easy to operate;
2. gather, collection process is in continuously, closed state, avoid gathering, cause biochemical pollution because of shifting function in the collection process;
3. collection tube is made by polypropylene, has improved safety;
4. gather, collection process is continuous, gather finish after, collection tube is extracted, the collecting pipe seal cover is sealing voluntarily immediately, gathers, acquisition time is short, efficient is high.
Description of drawings
Fig. 1 is this utility model structural profile sketch map, and collection tube runs through pipe cap and inserts in the collecting pipe, is in collection, collection status.
Fig. 2 is this utility model structural profile sketch map, and collection tube is extracted from pipe cap, and pipe cap is in closed state voluntarily.
Fig. 3 is pipe cap 2.2 generalized sections.
Fig. 4 is Fig. 3 vertical view.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Self-closed type shown in the drawings end is the blood collection tube slightly, and it comprises both ends open, leptosomatic collection tube 1 and collecting pipe 3, and described collecting pipe 3 is an open-topped tubular container; Described collection tube 1 adopts polypropylene to make, and inwall is through silicidation; The pipe cap 2 that is nested and closes with the collecting pipe 3 top mouths of pipe is set, and described pipe cap 2 is made by T-shaped glue, and it is made of cap 2.1 and medicated cap body 2.2; Described medicated cap body 2.2 is the circle tube member of " H " type for axial cross section, and cap 2.1 is for being connected the flange that turns up at medicated cap body 2.2 tops; 3～5 protruding circular arc ring 2.2.1 are set on medicated cap body 2.2 lower end outer walls constitute the elastic tensioning structure, protruding circular arc ring 2.2.1 external diameter bottom is than the big 0.5～0.9mm of collecting pipe 3 internal diameters, present embodiment is 0.7mm, all the other protruding circular arc ring 2.2.1 external diameters are than the big 0.2～0.4mm of collecting pipe 3 internal diameters, and present embodiment is 0.3mm; At medicated cap body 2.2 lower end ports taper guiding structure 2.2.3 is set, with slick and sly connection of protruding circular arc ring 2.2.1 bottom; Connect seal cover 2.2.2 in medicated cap body 2.2 inwall middle and lower parts, described seal cover 2.2.2 is that axial cross section is " V " type thin-wall member, 3～6 vertical masonry joints by the center is set constitutes self-enclosed structure, and present embodiment is 4.
Using this utility model to gather the end slightly during blood, collection tube 1 is run through pipe cap 2.2 inserts in the collecting pipes 3, with collection tube 1 upper end near the end slightly blood gather the position, end blood slightly flows in the collection tube 1.Because collection tube 1 inwall is through silicidation, inwall is very sliding, makes the end blood is very fast slightly to slip into the collecting pipe 3 from collection tube 1 inwall, therefore gathers continuously, and acquisition time is very short; Gatherer process is in closed state, because of collection tube 1, collecting pipe 3 separate, needs displacement during collection when avoiding gathering, and causes biochemical the pollution.
After finishing collection, collection tube 1 is extracted out from pipe cap 2.2, seal cover 2.2.2 seals voluntarily in the medicated cap body 2.2, and collecting pipe 3 is in sealing state.Just finished end collection, the approved sample work of blood slightly like this, in a short period of time.
Collection tube 3 is made by polypropylene, reduces and touch the probability of scratching child's hands because of child's hands in gatherer process.
Collection is finished, and when chemically examining, sample introduction needle directly penetrates from pipe cap 2.2, need not to open pipe cap 2.2 or punctures pipe cap 2.2, and is easy to operate, rapid.
